Method and device for collecting location information

TECHNICAL FIELD

The present invention relates to the field of communications technologies, and in particular, to a method and device for collecting location information.

BACKGROUND

As mobile communication network data increases explosively, operators hope that, in addition to providing a “transmission” pipe function, a current network can also provide an “information” pipe function, so as to implement information openness. In a mobile communication network, there are multiple uses for collecting location information of a mobile subscriber, for example, data analysis used in multiple industries. For example, location information may be used for transportation planning of a “smart city”. Population distribution is analyzed by using location information of mobile subscribers, so as to carry out work in, for example, smart transportation planning.

In the prior art, there is a method for acquiring location information of a user. Specifically, user equipment (UE) may locate a location of the user equipment by using a satellite, for example, locating by using a global positioning system (GPS). After a user logs in to a server by using an application program installed on the user equipment, the user equipment locates the location of the user equipment by using the satellite and reports location information to the server, and the server performs a further application operation according to the location information reported by the user equipment.

It is found that an application scenario of acquiring the location information of the user in the prior art is greatly limited, and universality is poor.

DESCRIPTION OF EMBODIMENTS

To make the objectives, features, and advantages of the present invention clearer and more comprehensible, the following describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the embodiments described in the following are merely some rather than all of the embodiments of the present invention. All other embodiments obtained by persons skilled in the art based on the embodiments of the present invention shall fall within the protection scope of the present invention.

In the specification, claims, and accompanying drawings of the present invention, the terms “include”, “comprise” and any other variants mean to cover the non-exclusive inclusion, so that a process, method, system, product, or device that includes a list of units is not necessarily limited to those units, but may include other units not expressly listed or inherent to such a process, method, system, product, or device.

Details are separately illustrated in the following.

In the present invention, an embodiment of a method for collecting location information may be applied to location information collection of user equipment, and the method may include: sending a location subscription instruction to user equipment (UE) by using a mobile communication network, where the location subscription instruction includes: instructing the UE to measure a cell detected by the UE; receiving instruction response information reported by the UE, where the instruction response information includes an identity (_ID) of the UE, an ID of the cell detected by the UE, and signal strength information of the cell detected by the UE; and acquiring location information of the UE according to the received instruction response information.

Referring to FIG. 1, a method for collecting location information provided in an embodiment of the present invention may include:

101. Send a location subscription instruction to UE by using a mobile communication network.

The location subscription instruction includes: instructing the UE to measure a cell detected by the UE.

In this embodiment of the present invention, because a device for collecting location information and the UE are on the same mobile communication network, there is a communication connection established between the device for collecting location information and the UE, so that communication between the device for collecting location information and the UE may be implemented.

First, when the device for collecting location information needs to collect a location information of the UE, the device for collecting location information may send the location subscription instruction to the UE by using the mobile communication network, and the device for collecting location information instructs, by using the location subscription instruction, the UE to measure the cell detected by the UE. It should be noted that a specific instruction format of the location subscription instruction sent by the device for collecting location information to the UE may be negotiated between the device for collecting location information and the UE, so as to determine an instruction format used for transferring the location subscription instruction, or an instruction format already constructed on the mobile communication network may be used to transfer the location subscription instruction. Specifically, how to transfer the location subscription instruction may be determined according to a network standard of the mobile communication network, or an existing signaling format on the mobile communication network may be modified or redefined, so as to be used for transferring the location subscription instruction. In addition, when the UE receives the location subscription instruction sent by the device for collecting location information, the UE may measure the cell detected by the UE.

102. Receive instruction response information reported by the UE.

The instruction response information includes an ID of the UE, an ID of the cell detected by the UE, and signal strength information of the cell detected by the UE.

In this embodiment of the present invention, after the device for collecting location information delivers the location subscription instruction to the UE, and after the UE measures, according to the location subscription instruction, the cell detected by the UE, the UE may acquire the ID of the cell detected by the UE and the signal strength information of the cell detected by the UE. The ID of the cell detected by the UE refers to an ID of a cell in which the UE is located and an ID of a neighboring cell. In addition, there may be one or more cells detected by the UE. The UE generates the instruction response information, and adds, to the instruction response information, the ID of the cell detected by the UE, the signal strength information of each cell detected by the UE, and the ID of the UE. The UE sends, by using the mobile communication network, the instruction response information to the device for collecting location information, and therefore, the device for collecting location information may receive, by using the mobile communication network, the instruction response information reported by the UE. The neighboring cell of the cell in which the UE is located refers to a cell adjacent to the cell in which the UE is located. Multiple neighboring cells of the cell in which the UE is located may be recorded in a Cell ID list of the neighboring cell. The signal strength information in each cell of the UE refers to signal strength of the cell in which the UE is located and signal strength of a neighboring cell of the cell in which the UE is located.

It should be noted that in this embodiment of the present invention, there may be multiple implementation manners of measuring, by the UE according to the location subscription instruction, the cell detected by the UE. For example, the UE may measure, in a manner that is for measuring the cell in which the UE is located and that exists in the mobile communication network, the cell detected by the UE, to generate the instruction response information of the UE and report the instruction response information of the UE to the device for collecting location information. In subsequent embodiments, for multiple standards of mobile communication networks and for different states of the UE on the mobile communication networks, that the UE measures the cell detected by the UE is described.

It should be noted that in some embodiments of the present invention, after the receiving instruction response information reported by the UE in step 102, the method may further include the following step:

encrypting the ID that is of the UE and that is included in the instruction response information, to obtain an anonymous identity, where the anonymous identity is in a one-to-one correspondence with the ID of the UE.

In some embodiments of the present invention, the ID that is of the UE and that is included in the instruction response information may be an international mobile subscriber identity (IMSI), or may certainly be another identity that identifies the UE. To avoid an unnecessary loss caused, to a user using the UE, by the location information of the UE, after receiving the instruction response information reported by the UE, the device for collecting location information may further encrypt the ID of the UE, to obtain the anonymous identity, where the anonymous identity is in a one-to-one correspondence with the ID of the UE. That is, anonymization processing on the ID of the UE may well ensure that privacy of the user is not leaked. In addition, an anonymous identity is further generated when anonymization processing is performed on the ID of the UE. Therefore, the location information of the UE may further correspond to the anonymous identity, and a further operation for the location information of the UE is not affected in subsequent application.

For example, an actual ID (the IMSI) of the user may be included when the UE reports the instruction response information to the device for collecting location information. Anonymizing the ID of the UE may implement encryption of the IMSI to obtain an IMSI′, thereby establishing a one-to-one correspondence between the IMSI and the IMSI′. When data analysis is performed on location information of UE, the IMSI′ is used to correspond to location information of the UE, and therefore, user privacy may be effectively protected from being leaked.

It should be noted that in this embodiment of the present invention, there may be multiple implementation manners of encrypting the ID of the UE. For example, the ID of the UE may be encrypted according to data encryption standard (DES). This algorithm has a relatively high speed and is applicable to a scenario in which a large amount of data is to be encrypted. Alternatively, the ID of the UE may also be encrypted according to international data encryption algorithm (IDEA). A 128-bit key is used in this algorithm, and therefore, extremely good security can be provided.

103. Acquire location information of the UE according to the received instruction response information.

In this embodiment of the present invention, after the device for collecting location information receives the instruction response information reported by the UE, the device for collecting location information may acquire the location information of the UE according to the received instruction response information. The location information refers to longitude and latitude location information of the UE. That is, the location of the UE is represented by using geographic coordinates.

There may be multiple implementation manners of acquiring the location information of the UE according to the received instruction response information. Based on the ID of the cell detected by the UE and the signal strength of each cell detected by the UE that are carried in the instruction response information, the ID of the cell detected by the UE may be acquired from the instruction response information; therefore, a base station to which the UE attaches may be determined. Because the base station is generally fixed at a location, and longitude and latitude location information is determined, first, a general location of the UE is determined, and then the location information of the UE may be obtained by means of precise calculation according to the signal strength in each cell of the UE.

It should be noted that in this embodiment of the present invention, the device for collecting location information may simultaneously deliver the location subscription instruction to multiple UEs, and each of the multiple UEs measures a cell detected by the UE, and then may acquire an ID of the cell detected by the UE. Each UE reports, by using the mobile communication network, instruction response information of the UE to the device for collecting location information, and the device for collecting location information may acquire multiple pieces of location information of the UEs, so that data analysis may further be performed on these pieces of location information of the UEs for application to a variety of industry applications such as transportation planning and marketing analysis.

It should be noted that in some embodiments of the present invention, specifically, the device for collecting location information may perform calculation on the received instruction response information, so as to acquire the location information of the UE. After obtaining the location information of the UEs by means of calculation, the device for collecting location information may send the location information to a data storage, analysis and open platform. The data storage, analysis and open platform performs further data analysis on these pieces of location information of the UEs for application to a variety of industry applications such as transportation planning and marketing analysis. The data storage, analysis and open platform, specially used for storing and analyzing big data, may be independent of an existing mobile communication network and may be a new device superimposed over the mobile communication network. In some other embodiments of the present invention, the acquiring location information of the UE according to the received instruction response information in step 103 may include the following step:

After the device for collecting location information receives the instruction response information reported by the UE, the device for collecting location information sends the received instruction response information to the data storage, analysis and open platform, and the data storage, analysis and open platform obtains the location information of the UE by means of calculation according to the instruction response information of the UE. That is, after the device for collecting location information receives the instruction response information of the UE, the data storage, analysis and open platform obtains the location information of the UE by means of calculation; therefore, distributed deployment of devices can be implemented to reduce a performance requirement on a single device, and calculation for the location information of the UE can also be implemented. For example, when the device for collecting location information has a limited calculation capability or load balancing needs to be performed, if a large amount of instruction response information reported by the UE is received, the device for collecting location information may obtain some location information of the UE by means of calculation, and sends instruction response information beyond the calculation capability of the device for collecting location information to the data storage, analysis and open platform, and the data storage, analysis and open platform obtains the other location information of the UE by means of calculation, so that distributed deployment of devices can be implemented.

It should be noted that in some embodiments of the present invention, the location subscription instruction includes: instructing the UE to measure, according to a preconfigured measurement period, the cell detected by the UE, where the receiving instruction response information reported by the UE in step 102 includes:

receiving multiple pieces of instruction response information reported by the UE according to the preconfigured measurement period; and

the acquiring location information of the UE according to the received instruction response information in step 103 includes:

obtaining location movement information of the UE by means of calculation according to the multiple pieces of received instruction response information.

If the location subscription instruction delivered by the device for collecting location information to the UE instructs the UE to measure, according to the preconfigured measurement period, the cell detected by the UE, the UE periodically measures the cell detected by the UE according to the preconfigured measurement period, and the UE generates instruction response information in every measurement period. For example, the measurement period is 12 seconds (s). Therefore the UE periodically generates multiple pieces of instruction response information. The device for collecting location information may receive the multiple pieces of instruction response information of the UE. After pieces of location information of the UE are separately obtained by means of calculation according to the multiple pieces of instruction response information of the UE, cluster analysis is performed on these pieces of location information of the UE obtained by means of calculation, and then the location movement information of the UE may be obtained by means of calculation. The location movement information refers to a movement and change status of the location of the UE within a time period, and generally, the location movement information may also be referred to as a digital footprint file; that is, a movement trail of the UE may be depicted by using the location movement information. Further data analysis performed on these pieces of information may be applied to a variety of industry applications such as transportation planning and marketing analysis. The preconfigured measurement period may be configured according to a requirement of an application service, impact on power consumption of the UE, and impact on network load, so as to achieve an optimal effect. Moreover, frequency of signaling reporting of the UE may be controlled according to the preconfigured measurement period, and therefore may be adjusted according to impact on network performance, avoiding causing too much impact on the network load. If the UE frequently reports signaling, an enormous amount of signaling needs to be processed, which increases a burden on the UE. Frequency that the UE reports the instruction response message may be adjusted by setting the measurement period, thereby not only meeting an application requirement but also avoiding increasing a great burden on the UE.

In this embodiment of the present invention, the UE is inevitably located on the mobile communication network. To locate the location of the UE, it is found by analyzing the mobile communication network that, as a cellular network, the mobile communication network may be used to locate the UE. For example, a cell to which the UE attaches on the cellular network may be used for performing locating. That is, the location of the UE is determined by using a location of the cell. Because a base station on a cellular network manages one or more cells, and UE attaches to the cell, the UE that attaches to the cell managed by the base station can be located by using a deployment location of the base station; therefore, location information of the UE is acquired.

It should be noted that in this embodiment of the present invention, collecting the location information of the UE may be implemented without requiring installing a specific application program on the UE or without requiring logging in to a server by the UE. In this embodiment of the present invention, the location information of the UE can be collected provided that the UE can normally communicate, and the method does not depend on a standard of the mobile communication network or a type of the UE. In this embodiment of the present invention, no matter whether the UE is an ordinary terminal or an intelligent terminal, provided that a wireless network signal is available, the location information of the UE can be successfully collected by using a communication connection between the device for collecting location information and the UE.

It can be learned from the foregoing description in this embodiment of the present invention that, first, a location subscription instruction is sent to UE by using a mobile communication network, so as to instruct the UE to measure, according to the location subscription instruction, a cell detected by the UE; after the UE generates, according to the location subscription instruction, an ID of the cell detected by the UE and signal strength information of the cell detected by the UE, instruction response information reported by the UE is received, where the instruction response information includes an ID of the UE, the ID of the cell detected by the UE, and the signal strength information of the cell detected by the UE; finally, location information of the UE may be acquired according to the received instruction response information. In this embodiment of the present invention, because a location subscription instruction may be delivered to UE, location information of the UE may be acquired according to received instruction response information reported by the UE, and the UE does not need to locate a location of the UE by using a satellite, electricity of the UE may be saved. For a mobile communication network, no matter whether the UE is indoors or outdoors, the instruction response information reported by the UE can be received provided that a wireless network signal is available. In addition, in this embodiment of the present invention, the location information of the UE can be acquired by using the existing mobile communication network, and the UE does not need to successfully log in to a server by using a specific application program; therefore, a problem of application program promotion does not exist. Therefore, the method for collecting location information provided in this embodiment of the present invention is not limited to an application scenario such as an indoor scenario, an outdoor scenario, or whether an application program is installed; universality is very strong.

Details are described in the following for standards of different mobile communication networks and states of the UE on the mobile networks. However, the following embodiments provide only some standards of mobile communication networks, which may be applied to other standards of mobile communication networks according to technical features described in the embodiments of the present invention. The description herein is only for an illustration purpose, and is not used to limit the present invention.

Referring to FIG. 2, when a mobile communication network is a universal mobile telecommunications system (UMTS) network, a method for collecting location information provided in another embodiment of the present invention may include the following steps:

201. When UE is in a cell-dedicated channel (Cell DCH) state on the UMTS network, a radio network controller (RNC) sends a measurement control message to the UE by using the UMTS network, so that the UE measures, according to the measurement control message, a cell detected by the UE.

When the UE is in the Cell DCH state on the UMTS network, the RNC sends the measurement control message to the UE by using the UMTS network. The sending a location subscription instruction to UE by using a mobile communication network in the foregoing embodiment may be: sending, by the RNC, the Measurement Control message to the UE by using the UMTS network, so that the UE may measure, according to an instruction of the Measurement Control message, the cell detected by the UE. After measuring, according to the Measurement Control message, the cell detected by the UE, the UE may generate an ID of a cell in which the UE is located and an ID of a neighboring cell of the cell. Afterward, the UE generates a measurement report message, and adds, to the Measurement Report message, an ID of the cell detected by the UE and signal strength information of the cell detected by the UE, and then the UE may send the Measurement Report message to the RNC.

202. The RNC receives a measurement report message sent by the UE.

The measurement report message includes an ID of the UE, the ID of the cell detected by the UE, and the signal strength information of the cell detected by the UE.

The RNC may receive, by using the UMTS network, the Measurement Report message reported by the UE, and therefore may acquire the ID of the UE, the ID of the cell detected by the UE, and the signal strength information of the cell detected by the UE, and may implement locating of the UE according to the information.

It should be noted that in this embodiment of the present invention, the UE may periodically report the Measurement Report message to the RNC, for example, report the Measurement Report message of the UE once every 12 s, and the Measurement Report message may be the instruction response information described in the foregoing embodiment. In addition, the UE also reports the Measurement Report message to the RNC when the UE initiates handover, and the Measurement Report message may also be used for location calculation for the UE. Because a piece of longitude and latitude location information of the UE may be obtained by means of calculation according to each Measurement Report message, location movement trail information of the UE may be obtained.

203. The RNC acquires location information of the UE according to the received measurement report message.

It should be noted that the measurement report message is the instruction response information reported by the UE in the foregoing embodiment. In some embodiments of the present invention, specifically, the RNC may perform calculation on the received instruction response information, so as to acquire the location information of the UE. After obtaining location information of the UE by means of calculation, the RNC may send the location information to a data storage, analysis and open platform. The data storage, analysis and open platform performs further data analysis on these pieces of location information of the UE for application to a variety of industry applications such as transportation planning and marketing analysis. The data storage, analysis and open platform, specially used for storing and analyzing big data, may be independent of an existing mobile communication network and may be a new device superimposed over the mobile communication network. In some other embodiments of the present invention, the RNC may also send the received instruction response information to a data storage, analysis and open platform, and the data storage, analysis and open platform obtains the location information of the UE by means of calculation according to the instruction response information.

After the RNC receives the instruction response information reported by the UE, the RNC sends the received instruction response information to the data storage, analysis and open platform, and the data storage, analysis and open platform obtains the location information of the UE by means of calculation according to the instruction response information of the UE. That is, after the RNC receives the instruction response information of the UE, the data storage, analysis and open platform obtains the location information of the UE by means of calculation; therefore, distributed deployment of devices can be implemented to reduce a performance requirement on a single device, and calculation for the location information of the UE can also be implemented. For example, when the RNC has a limited calculation capability or load balancing needs to be performed, if a large amount of instruction response information reported by the UE is received, the RNC may obtain some location information of the UE by means of calculation, and sends instruction response information beyond a calculation capability of the RNC to the data storage, analysis and open platform, and the data storage, analysis and open platform obtains the other location information of the UE by means of calculation, so that distributed deployment of devices can be implemented.

It should be noted that in this embodiment of the present invention, when the UE is in the Cell DCH state on the UMTS network, because the location information of the UE may be acquired by using the measurement report message sent by the UE, the location information of the UE can be acquired no matter whether the UE performs a circuit switched (CS) domain service or a packet switched (PS) domain service. In another method for collecting location information existing in the prior art, a standard Iu interface message is acquired by disposing a probe on an Iu interface, so as to acquire location information of UE. In this external probe solution, only location information existing when the UE is on a CS domain voice call is collected, and location information existing when the UE performs PS domain data communication cannot be collected. In this embodiment of the present invention, the location information of the UE can be acquired no matter whether the UE performs a CS domain service or a PS domain service.

It can be learned from the foregoing description in this embodiment of the present invention that, because an RNC in this embodiment of the present invention may deliver a location subscription instruction to UE, and may acquire location information of the UE according to a received measurement report message sent by the UE, and the UE does not need to locate a location of the UE by using a satellite, electricity of the UE may be saved. For a mobile communication network, no matter whether the UE is indoors or outdoors, the measurement report message sent by the UE can be received provided that a wireless network signal is available. In addition, in this embodiment of the present invention, the location information of the UE can be acquired by using the existing mobile communication network, and the UE does not need to successfully log in to a server by using a specific application program. Therefore, the method for collecting location information provided in this embodiment of the present invention is not limited to an application scenario such as an indoor scenario, an outdoor scenario, or whether an application program is installed; universality is very strong.

Referring to FIG. 3, when a mobile communication network is a UMTS network, in a method for collecting location information provided in another embodiment of the present invention, receiving instruction response information reported by UE may include the following steps:

301. When the UE is in an idle mode on the UMTS network, an RNC receives an RRC connection request message sent by the UE.

The RRC connection request message includes an ID of the UE, an ID of a cell detected by the UE, and signal strength information of the cell detected by the UE.

In this embodiment of the present invention, when the mobile communication network is the UMTS network, a device for collecting location information may be the RNC. Because the RNC and the UE are on the same UMTS network, there is a communication connection established between the RNC and the UE, so that communication between the RNC and the UE may be implemented. When the UE is in the idle mode on the UMTS network, the UE generates the radio resource control (RRC) connection request message, and adds, to the RRC connection request message, the ID of the UE, the ID of the cell detected by the UE, and the signal strength information of the cell detected by the UE; then, the UE may send the RRC connection request message to the RNC.

When the UE is in the Idle mode on the UMTS network, the RNC receives, by using the UMTS network, the RRC connection request message sent by the UE. After the RNC acquires, from the RRC connection request message, the ID of the UE, the ID of the cell detected by the UE, and the signal strength information of the cell detected by the UE, the RNC sends an RRC connection setup message to the UE by using the UMTS network. It should be noted that when the UE is in the Idle mode on the UMTS network, an ordinary location update, a periodic location update, and an attach process of the UE are all non-access stratum (NAS) messages from the UE to a core network. Before sending the NAS message, the UE needs to execute an RRC connection setup process first, and therefore the RNC may acquire the instruction response information of the UE by using a message in the RRC connection setup process.

302. The RNC acquires location information of the UE according to the received RRC connection request message.

It should be noted that the RRC connection request message is the instruction response information reported by the UE in the foregoing embodiment. In some embodiments of the present invention, specifically, the RNC may perform calculation on the received instruction response information, so as to acquire the location information of the UE. After obtaining location information of the UE by means of calculation, the RNC may send the location information to a data storage, analysis and open platform. The data storage, analysis and open platform performs further data analysis on these pieces of location information of the UE for application to a variety of industry applications such as transportation planning and marketing analysis. The data storage, analysis and open platform, specially used for storing and analyzing big data, may be independent of an existing mobile communication network and may be a new device superimposed over the mobile communication network. In some other embodiments of the present invention, the RNC may also send the received instruction response information to a data storage, analysis and open platform, and the data storage, analysis and open platform obtains the location information of the UE by means of calculation according to the instruction response information.

It should be noted that in this embodiment of the present invention, when the UE is in the Idle mode on the UMTS network, the UE generally cannot periodically acquire the location information of the UE as the UE does in a Cell DCH state, and therefore obtains relatively less location information. Therefore, the method is suitable for performing statistical trend analysis on clustered locations of users on the entire UMTS network.

It should be noted that in this embodiment of the present invention, when the UE is in the Idle mode on the UMTS network, because the location information of the UE can be acquired by using the RRC connection request message sent by the UE, the location information of the UE can be acquired no matter whether the UE performs a CS domain service or a PS domain service. In another method for collecting location information existing in the prior art, a standard Iu interface message is acquired by disposing a probe on an Iu interface, so as to acquire location information of UE. In this external probe solution, only location information existing when the UE is on a CS domain voice call is collected, and location information existing when the UE performs PS domain data communication cannot be collected. In this embodiment of the present invention, the location information of the UE can be acquired no matter whether the UE performs a CS domain service or a PS domain service.

It can be learned from the foregoing description in this embodiment of the present invention that, because an RNC in this embodiment of the present invention can acquire location information of UE according to a received RRC connection request message reported by the UE, and the UE does not need to locate a location of the UE by using a satellite, electricity of the UE may be saved. For a mobile communication network, no matter whether the UE is indoors or outdoors, the RRC connection request message reported by the UE can be received provided that a wireless network signal is available. In addition, in this embodiment of the present invention, the location information of the UE can be acquired by using the existing mobile communication network, and the UE does not need to successfully log in to a server by using a specific application program. Therefore, the method for collecting location information provided in this embodiment of the present invention is not limited to an application scenario such as an indoor scenario, an outdoor scenario, or whether an application program is installed; universality is very strong.

Referring to FIG. 4, when a mobile communication network is a UMTS network, in a method for collecting location information provided in another embodiment of the present invention, receiving instruction response information reported by UE may include the following steps:

401. When the UE is in a Cell FACH state, a Cell PCH state, or a URA PCH state on the UMTS network, an RNC receives a Cell Update message sent by the UE.

The Cell Update message includes an ID of the UE, an ID of a cell detected by the UE, and signal strength information of the cell detected by the UE.

In this embodiment of the present invention, when the mobile communication network is the UMTS network, a device for collecting location information may be the RNC. Because the RNC and the UE are on the same UMTS network, there is a communication connection established between the RNC and the UE, so that communication between the RNC and the UE may be implemented. When the UE is in the cell-forward access channel (Cell FACH) state, the cell paging channel (Cell PCH) state, or the Universal Mobile Telecommunications System terrestrial radio access network registration area paging channel (Universal Mobile Telecommunications System Terrestrial Radio Access Network Registration Area, URA PCH) state on the UMTS network, the UE generates the cell update message, and adds, to the Cell Update message, an ID of a cell in which the UE is located, the ID of the cell detected by the UE, and the signal strength information of the cell detected by the UE; then, the UE may send the Cell Update message to the RNC.

When the UE is in the Cell FACH state, the Cell PCH state, or the URA PCH state on the UMTS network, the RNC receives, by using the UMTS network, the Cell Update message sent by the UE. After the RNC acquires, from the Cell Update message, the ID of the UE, the ID of the cell detected by the UE, and the signal strength information of the cell detected by the UE, the RNC sends a cell update confirm message to the UE by using the UMTS network. It should be noted that when the UE is in the URA PCH state on the UMTS network, the RNC can acquire location information of the UE provided that the RNC initiates a cell update process only after a URA in which the UE is located changes.

402. The RNC acquires location information of the UE according to the received Cell Update message.

It should be noted that the Cell Update message is the instruction response information reported by the UE in the foregoing embodiment. In some embodiments of the present invention, specifically, the RNC may perform calculation on the received instruction response information, so as to acquire the location information of the UE. After obtaining location information of the UE by means of calculation, the RNC may send the location information to a data storage, analysis and open platform. The data storage, analysis and open platform performs further data analysis on these pieces of location information of the UE for application to a variety of industry applications such as transportation planning and marketing analysis. The data storage, analysis and open platform, specially used for storing and analyzing big data, may be independent of an existing mobile communication network and may be a new device superimposed over the mobile communication network. In some other embodiments of the present invention, the RNC may also send the received instruction response information to a data storage, analysis and open platform, and the data storage, analysis and open platform obtains the location information of the UE by means of calculation according to the instruction response information.

It should be noted that in this embodiment of the present invention, when the UE is in the Cell FACH state, the Cell PCH state, or the URA PCH state on the UMTS network, because the location information of the UE can be acquired by using the Cell Update message sent by the UE, the location information of the UE can be acquired no matter whether the UE performs a CS domain service or a PS domain service. In another method for collecting location information existing in the prior art, a standard Iu interface message is acquired by disposing a probe on an Iu interface, so as to acquire location information of UE. In this external probe solution, only location information existing when the UE is on a CS domain voice call is collected, and location information existing when the UE performs PS domain data communication cannot be collected. In this embodiment of the present invention, the location information of the UE can be acquired no matter whether the UE performs a CS domain service or a PS domain service.

It can be learned from the foregoing description in this embodiment of the present invention that, because an RNC in this embodiment of the present invention can acquire location information of UE according to a received Cell Update message reported by the UE, and the UE does not need to locate a location of the UE by using a satellite, electricity of the UE may be saved. For a mobile communication network, no matter whether the UE is indoors or outdoors, the Cell Update message reported by the UE can be received provided that a wireless network signal is available. In addition, in this embodiment of the present invention, the location information of the UE can be acquired by using the existing mobile communication network, and the UE does not need to successfully log in to a server by using a specific application program. Therefore, the method for collecting location information provided in this embodiment of the present invention is not limited to an application scenario such as an indoor scenario, an outdoor scenario, or whether an application program is installed; universality is very strong.

It should be noted that when a mobile communication network is a UMTS network, in the foregoing methods for collecting location information that are shown in FIG. 2 to FIG. 4 in the embodiments of the present invention, for signal strength information that is in each cell of the UE and that is included in the measurement report message, the signal strength information that is in each cell of the UE and that is included in the RRC connection request message, and the signal strength information that is in each cell of the UE and that is included in the Cell Update message, the signal strength information is received signal code power (RSCP) information or ratio of energy per modulating bit to the noise spectral density Ec/No (where Ec is energy per chip per code channel after a spectrum is expanded at a transmit end, No is a power spectral density of a band-limited white noise, and a ratio of the Ec and the No is referred to as Ec/No for short) information.

Referring to FIG. 5, when a mobile communication network is a long term evolution (LTE) network, a method for collecting location information provided in another embodiment of the present invention may include the following steps:

501. When UE is in a connected mode on the LTE network, an evolved NodeB (eNodeB) sends a measurement control message to the UE by using the LTE network, so that the UE measures, according to the measurement control message, a cell detected by the UE.

In this embodiment of the present invention, when the mobile communication network is the LTE network, a device for collecting location information may be the eNodeB. Because the eNodeB and the UE are on the same LTE network, there is a communication connection established between the eNodeB and the UE, so that communication between the eNodeB and the UE may be implemented. The eNodeB delivers the measurement control message to the UE by using the LTE network, and the UE may measure, according to an instruction of the measurement control message, the cell detected by the UE. After measuring, according to the measurement control message, the cell detected by the UE, the UE may generate an ID of a cell in which the UE is located and an ID of a neighboring cell of the cell. When the UE is in the connected mode on the LTE network, the UE generates a measurement report message, and adds, to the measurement report message, the ID of the cell in which the UE is located, the ID of the neighboring cell of the cell, an ID of the UE, and signal strength information in each cell of the UE; then, the UE may send the measurement report message to the eNodeB.

502. The eNodeB receives a measurement report message sent by the UE.

The measurement report message includes the ID of the UE, an ID of the cell detected by the UE, and signal strength information of the cell detected by the UE.

When the UE is in the connected mode on the LTE network, the eNodeB receives, by using the LTE network, the measurement report message sent by the UE. It should be noted that in this embodiment of the present invention, the UE may periodically report the Measurement Report message to the eNodeB, for example, report the Measurement Report message of the UE once every 12 s, and the Measurement Report message may be the instruction response information described in the foregoing embodiment. In addition, the UE also reports the Measurement Report message to the eNodeB when the UE initiates handover, and the Measurement Report message may also be used for location calculation for the UE. Because a piece of longitude and latitude location information of the UE may be obtained by means of calculation according to each Measurement Report message, location movement trail information of the UE may be obtained.

It should be noted that in a mobile communication network whose standard is LTE, because identity information (for example, an IMSI) of the UE cannot be acquired on a radio access network (RAN) side, each piece of location information of the UE needs to be acquired by means of coordination between the RAN side and an evolved packet core (EPC) and by using an S1 application protocol identity (AP ID) as a link of association. After receiving the measurement report message sent by the UE, the eNodeB associates a cell message of the UE with an S1 AP ID of the UE. Then, after acquiring the location information of the UE, the eNodeB forms an association between the location information of the UE and the S1 AP ID of the UE. The EPC may acquire the identity information (for example, an IMSI) of the UE, and forms an association with the S1 AP ID of the UE. Then, the eNodeB obtains, by using the S1 AP ID of the UE, a combination relationship between the location information of the UE and the ID of the UE from the two associations.

503. The eNodeB acquires location information of the UE according to the received measurement report message.

It can be learned from the foregoing description in this embodiment of the present invention that, because an eNodeB in this embodiment of the present invention may deliver a location subscription instruction to UE, and may acquire location information of the UE according to a received measurement report message sent by the UE, and the UE does not need to locate a location of the UE by using a satellite, electricity of the UE may be saved. For a mobile communication network, no matter whether the UE is indoors or outdoors, the measurement report message sent by the UE can be received provided that a wireless network signal is available. In addition, in this embodiment of the present invention, the location information of the UE can be acquired by using the existing mobile communication network, and the UE does not need to successfully log in to a server by using a specific application program. Therefore, the method for collecting location information provided in this embodiment of the present invention is not limited to an application scenario such as an indoor scenario, an outdoor scenario, or whether an application program is installed; universality is very strong.

Referring to FIG. 6, when a mobile communication network is an LTE network, in a method for collecting location information provided in another embodiment of the present invention, receiving instruction response information reported by UE may include the following steps:

601. When the UE is in an idle mode on the LTE network, an eNodeB receives an RRC connection request message sent by the UE.

The RRC connection request message includes an ID of the UE, an ID of a cell detected by the UE, and signal strength information of the cell detected by the UE.

The eNodeB sends a location subscription instruction to the UE by using the LTE network, so that the UE measures, according to the location subscription instruction, the cell detected by the UE.

602. The eNodeB acquires location information of the UE according to the received RRC connection request message.

It can be learned from the foregoing description in this embodiment of the present invention that, because an eNodeB in this embodiment of the present invention can acquire location information of UE according to a received RRC connection request message reported by the UE, and the UE does not need to locate a location of the UE by using a satellite, electricity of the UE may be saved. For a mobile communication network, no matter whether the UE is indoors or outdoors, the RRC connection request message reported by the UE can be received provided that a wireless network signal is available. In addition, in this embodiment of the present invention, the location information of the UE can be acquired by using the existing mobile communication network, and the UE does not need to successfully log in to a server by using a specific application program. Therefore, the method for collecting location information provided in this embodiment of the present invention is not limited to an application scenario such as an indoor scenario, an outdoor scenario, or whether an application program is installed; universality is very strong.

It should be noted that when the mobile communication network is the LTE network, in the foregoing methods for collecting location information that are shown in FIG. 5 and FIG. 6 in the embodiments of the present invention, for the signal strength information that is in each cell of the UE and that is included in the measurement report message and the signal strength information that is in each cell of the UE and that is included in the RRC connection request message, the signal strength information is reference signal received power (RSRP) information or reference signal received quality (RSRQ) information.

Referring to FIG. 7, when a mobile communication network is a global system for mobile communications (GSM) network, a method for collecting location information provided in another embodiment of the present invention may include the following steps:

701. When UE is in a general packet radio service transfer (GPRS Transfer) state on the GSM network, a base station controller (BSC) sends a measurement control message to the UE by using the GSM network, so that the UE measures, according to the measurement control message, a cell detected by the UE.

In this embodiment of the present invention, when the mobile communication network is the GSM network, a device for collecting location information may be the BSC. Because the BSC and the UE are on the same GSM network, there is a communication connection established between the BSC and the UE, so that communication between the BSC and the UE may be implemented. The BSC delivers the measurement control message to the UE by using the GSM network, and the UE may measure, according to an instruction of the measurement control message, the cell detected by the UE. After measuring, according to the measurement control message, the cell detected by the UE, the UE may generate an ID of a cell in which the UE is located and an ID of a neighboring cell of the cell. When the UE is in the GPRS Transfer mode on the GSM network, the UE generates a measurement report message, and adds, to the measurement report message, the ID of the cell in which the UE is located, the ID of the neighboring cell of the cell, an ID of the cell detected by the UE, and signal strength information of the cell detected by the UE; then, the UE may send the measurement report message to the BSC.

702. The BSC receives a measurement report message sent by the UE.

The measurement report message includes an ID of the UE, the ID of the cell detected by the UE, and the signal strength information of the cell detected by the UE.

When the UE is in the GPRS Transfer mode on the GSM network, the BSC receives, by using the GSM network, the measurement report message sent by the UE. It should be noted that in this embodiment of the present invention, the UE may periodically report the Measurement Report message to the BSC, for example, report the Measurement Report message of the UE once every 12 s, where the Measurement Report message may be the instruction response information described in the foregoing embodiment. In addition, the UE also reports the Measurement Report message to the BSC when the UE initiates handover, and the Measurement Report message may also be used for location calculation for the UE. Because a piece of longitude and latitude location information of the UE may be obtained by means of calculation according to each Measurement Report message, location movement trail information of the UE may be obtained.

703. The BSC acquires location information of the UE according to the received measurement report message.

It can be learned from the foregoing description in this embodiment of the present invention that, because a BSC in this embodiment of the present invention may deliver a location subscription instruction to UE, and may acquire location information of the UE according to a received measurement report message sent by the UE, and the UE does not need to locate a location of the UE by using a satellite, electricity of the UE may be saved. For a mobile communication network, no matter whether the UE is indoors or outdoors, the measurement report message sent by the UE can be received provided that a wireless network signal is available. In addition, in this embodiment of the present invention, the location information of the UE can be acquired by using the existing mobile communication network, and the UE does not need to successfully log in to a server by using a specific application program. Therefore, the method for collecting location information provided in this embodiment of the present invention is not limited to an application scenario such as an indoor scenario, an outdoor scenario, or whether an application program is installed; universality is very strong.

Referring to FIG. 8, when a mobile communication network is a GSM network, in a method for collecting location information provided in another embodiment of the present invention, receiving instruction response information reported by UE may include the following steps:

801. When the UE is in a GPRS Packet Idle mode on the GSM network, a BSC receives a connection request message sent by the UE.

The connection request message includes an ID of the UE, an ID of a cell in which the UE is located, an ID of a neighboring cell of the cell, and signal strength information in each cell of the UE.

802. The BSC acquires location information of the UE according to the received connection request message.

It can be learned from the foregoing description in this embodiment of the present invention that, because a BSC in this embodiment of the present invention can acquire location information of UE according to a received connection request message reported by the UE, and the UE does not need to locate a location of the UE by using a satellite, electricity of the UE may be saved. For a mobile communication network, no matter whether the UE is indoors or outdoors, the connection request message reported by the UE can be received provided that a wireless network signal is available. In addition, in this embodiment of the present invention, the location information of the UE can be acquired by using the existing mobile communication network, and the UE does not need to successfully log in to a server by using a specific application program. Therefore, the method for collecting location information provided in this embodiment of the present invention is not limited to an application scenario such as an indoor scenario, an outdoor scenario, or whether an application program is installed; universality is very strong.

It should be noted that when the mobile communication network is the GSM network, in the foregoing methods for collecting location information that are shown in FIG. 7 and FIG. 8 in the embodiments of the present invention, for the signal strength information that is in each cell of the UE and that is included in the measurement report message and the signal strength information that is in each cell of the UE and that is included in the RRC connection request message, the signal strength information is received signal strength indicator (RSSI) information.

It should be noted that the embodiments of the present invention are described above in detail by using multiple standards of mobile communication networks shown in FIG. 2 to FIG. 8 as examples. However, the embodiments of the present invention are not limited to the foregoing described UMTS network, LTE network, and GSM network. The method for collecting location information provided in the embodiments of the present invention may also be applied to other network standards of mobile communication networks. For example, the method for collecting location information in the present invention may also be applied to multiple standards of mobile communication networks, such as a Code Division Multiple Access (CDMA) network, a time division-synchronous code division multiple access (TD-SCDMA) network, a worldwide interoperability for microwave access (Wimax) network, and a wireless local area network (WLAN) network. On the CDMA network, the TD-SCDMA network, the Wimax network, and the WLAN network, the location information of the UE may be acquired according to a specific network architecture and a specific protocol manner. The description herein is only for an illustration purpose.

To better understand and implement the foregoing solutions in the embodiments of the present invention, the following provides detailed description by using corresponding application scenarios as examples.

Referring to FIG. 9, FIG. 9 is a schematic diagram of composition of a network architecture of a system for collecting location information that is implemented according to a method for collecting location information according to an embodiment of the present invention. The following illustrative description is made as a process of data subscription, collection and reporting.

The network architecture of the system for collecting location information that is implemented according to the method for collecting location information and that is provided in this embodiment of the present invention is divided into three layers: a source data collection layer, a data aggregation, analysis and open layer, and a data application layer.

Referring to FIG. 10, FIG. 10 is a schematic diagram of a work process of each component in a system for collecting location information according to an embodiment of the present invention, and the process mainly includes the following steps:

S01. A third-party application server enters an application-specific data subscription request into a data storage, analysis and open platform according to a requirement of the third-party application server, so as to request for location information data of a user.

S02. The data storage, analysis and open platform sends, according to the request of the application server, the data subscription request to a device for collecting location information, where an example in which the device for collecting location information refers to a network element on a mobile communication network is used for description, and each network element on the mobile communication network receives the data subscription request sent by the data storage, analysis and open platform, so as to subscribes to radio signaling required for locating a location of the user.

S03. Each network element on the mobile communication network starts a signaling collection process, that is, a network element on a radio access network (RAN) side starts an information collection process, where for a GSM network, the network element on the RAN side refers to a BSC; for a UMTS network, the network element on the RAN side refers to an RNC; and for an LTE network, the network element on the RAN side refers to an eNodeB.

S04. The network element on the RAN side delivers a location subscription instruction to UE, so as to instruct the UE to periodically measure a cell detected by the UE.

S05a. The UE reports instruction response information of the UE, where the instruction response information includes an ID of the UE, an ID of the cell detected by the UE, and signal strength information of the cell detected by the UE.

S05b. The UE reports instruction response information of the UE again according to a measurement period.

S06. The network element on the RAN side obtains location information of the UE by means of calculation according to the instruction response information reported by the UE.

S07. The network element on the RAN side reports the location information of the UE to the data storage, analysis and open platform.

S08. The data storage, analysis and open platform stores and analyzes the location information of the UE, provides an external digital footprint file that includes the location information of the UE, and uploads a data analysis result to the application server, so as to implement responding to the request of the application server. After obtaining the digital footprint file from the data storage, analysis and open platform, the third-party application server applies the information to industry analysis.

It should be noted that as described above, step S06 is described by using an example in which the network element on the RAN side obtains the location information of the UE by means of calculation. In some other embodiments of the present invention, after the network element on the RAN side receives the instruction response information reported by the UE, the network element on the RAN side may further directly upload a cell message of the UE to the data storage, analysis and open platform, and the data storage, analysis and open platform obtains the location information of the UE by means of calculation. Specifically, in some embodiments of the present invention, after obtaining a location of the UE by means of calculation, the data aggregation, analysis and open layer outputs a data analysis result to the data application layer, where as shown in Table 1, the data analysis result may include the following fields:
