The present invention relates to the communications field, and in particular, to a detecting apparatus, and a method for determining air interface resources consumed by a service.
In recent years, packet switched (Packet Switch, PS) data services develop rapidly, bringing an increase in income to operators, and at the same time, a large number of wireless network resources are occupied. A PS network carries diverse service types. For different types of data services, for example, video, social networking or other applications, a respectively unique traffic model is formed because of diversity of user groups and application characteristics of services, which directly leads to different statuses of occupation of wireless air interface resources. The operators can better use service promotions and guide configuration of network resources by determining statuses of occupation of air interface resources by different types of services.
For example, an operator considers that a service in which air interface duration consumed per megabyte of traffic is more than one hour is an inefficient service, which easily causes air interface congestion, and that a service in which a quantity of times of connection consumed per megabyte of traffic is more than 100 is an inefficient service, which easily causes a signaling storm. These services should be priorities to manage and optimize.
At present, the operator generally collects statistics, by using a manual dialing test method, about a situation of occupation of air interface resources by a service. For example, in a specialized laboratory, specialized professional personnel uses a special testing mobile phone or other tools to collect statistics about a situation of occupation of air interface resources by a service, for example, air interface duration consumed by the service or a quantity of times of air interface connection consumed by the service. This testing manner requires a lot of manpower and material resources, and has a very high cost.
In view of the foregoing problem, the operator begins to use a manner of deploying an external probe system to collect statistics about a situation of occupation of air interface resources by a service. The external probe system may collect a transmission interval of Internet Protocol (Internet Protocol, IP) packets between a user equipment (User Equipment, UE) and an access network, and calculate, according to the transmission interval of IP packets, air interface duration consumed by the service or a quantity of times of air interface connection caused by the service. Generally, the UE has a dormant time. After a wireless connection is established, if sending of IP packets between the UE and the access network is completed, the UE enters a dormant state; and when a dormant timer of the UE expires, the UE releases the wireless connection. Therefore, in order to calculate the air interface duration or the quantity of times of air interface connection, the external probe also needs to correspondingly set a dormant time. However, different UEs have different dormant times, and the external probe cannot set a different dormant time for each type of UE. Therefore, although the external probe system reduces, to some extent, the high cost generated by the manual dialing test, accuracy of a statistical result cannot be ensured.

It may be considered that within a period of time from the time point at which the UE starts transmitting the data of the service to the time point at which the UE stops transmitting the data of the service, the UE performs data transmission of the service once. The data plane entity 130 may send, to the detecting apparatus 110 at a time, multiple groups of time points at which the UE starts and stops transmitting the data of the service, or may send, to the detecting apparatus 110 at a time, one group of time points at which the UE starts and stops transmitting the data of the service, or may send, to the detecting apparatus 110 at a time, a time point at which the UE starts transmitting the data of the service or a time point at which the UE stops transmitting the data of the service. A person skilled in the art may understand that the foregoing descriptions are merely examples of manners in which the data plane entity 130 sends the service information of the UE to the detecting apparatus 110, and there may be many other manners, which is not limited in this embodiment of the present invention. The service described above includes a to-be-detected service, and may further include another service. In this embodiment of the present invention, the to-be-detected service refers to a service for which statistics about air interface resource consumption needs to be collected. The data plane entity 130 may record, only for the to-be-detected service of the UE, time points at which the UE starts and stops transmitting data of the to-be-detected service, and send the time points to the detecting apparatus 110, or may record, for all services of the UE, time points at which the UE starts and stops transmitting data of the services, and send the time points to the detecting apparatus 110, which is not limited in this embodiment of the present invention.
After receiving the air interface connection information and the service information of the UE, the detecting apparatus 110 may determine a target air interface connection set according to the received air interface connection information and service information, where the target air interface connection set includes one or more target air interface connections.
Exemplarily, the detecting apparatus 110 may determine, according to the air interface connection information, a period of time A from establishing to releasing the air interface connection, and the detecting apparatus may determine, according to the service information, a period of time B from starting to stopping one data transmission of the to-be-detected service; when the period of time A includes the period of time B, for example, the period of time A is 8:00-9:00, and the period of time B is 8:15-8:20, it may be determined that data of the to-be-detected service is transmitted on this air interface connection once. In this embodiment of the present invention, an air interface connection transmitting data of the to-be-detected service is referred to as a target air interface connection. A person skilled in the art may understand that one target air interface connection may transmit data of the to-be-detected service for multiple times. A person skilled in the art may understand that criteria for determining a target air interface connection may be different according to different requirements, for example, an air interface connection that transmits data of the to-be-detected service and whose duration exceeds a threshold is considered as a target air interface connection. Therefore, the target air interface connection may be further understood as an air interface connection that meets a particular condition and transmits data of the to-be-detected service, where the particular condition that needs to be met is not limited in this embodiment of the present invention. Although there may be different understandings about the target air interface connection, it may be understood that the target air interface connection is an air interface connection transmitting data of the to-be-detected service.
The detecting apparatus 110 may determine one or more target air interface connections according to the air interface connection information and the service information of the UE. For ease of description, the one or more target air interface connections determined by the detecting apparatus 110 may be referred to as a target air interface connection set, that is, the target air interface connection set includes one or more target air interface connections. After determining the target air interface connection set, the detecting apparatus 110 may determine air interface resource consumption information of the to-be-detected service according to the target air interface connection set. Exemplarily, the air interface resource consumption information may include consumed air interface duration, a quantity of times of air interface connection that is consumed, or consumed air interface traffic, which is not limited in this embodiment of the present invention.
As an optional solution for acquiring air interface resource consumption information of the to-be-detected service, the detecting apparatus 110 may determine air interface duration consumed by the to-be-detected service.
Exemplarily, after determining the target air interface connection set, the detecting apparatus 110 may determine, according to air interface duration consumed on each target air interface connection in the target air interface connection set by the to-be-detected service, the air interface duration consumed by the to-be-detected service. Air interface duration consumed on a single target air interface connection by the to-be-detected service may be determined by using the following method.
201: Determine connection duration of the target air interface connection according to the air interface connection information.
202: Determine, according to the air interface connection information and the service information of the UE, whether the target air interface connection transmits data of another service.
203: If the target air interface connection does not transmit data of the another service, determine that air interface duration consumed on the target air interface connection by the to-be-detected service is the connection duration of the target air interface connection.
204: If the target air interface connection transmits data of the another service, determine, according to transmission consumption of the data of the to-be-detected service on the target air interface connection, transmission consumption of the data of the another service on the target air interface connection, and the connection duration of the target air interface connection, air interface duration consumed on the target air interface connection by the to-be-detected service.
Steps 201, 202, and 203 may constitute one technical solution, and steps 201, 202, and 204 may also constitute one technical solution.
Exemplarily, in a case in which the target air interface connection does not transmit data of the another service, air interface duration consumed on the target air interface connection by the to-be-detected service may be further determined according to another condition or formula, which is not limited in this embodiment of the present invention. For example, accumulative duration of transmitting data of the to-be-detected service on the target air interface connection is used as the air interface duration consumed on the target air interface connection.
Exemplarily, in a case in which the target air interface connection transmits data of the another service, the air interface duration consumed on the target air interface connection by data of the to-be-detected service may be determined through comparison between the transmission consumption of the data of the to-be-detected service on the target air interface connection and the transmission consumption of the data of the another service on the target air interface connection. The transmission consumption in this embodiment of the present invention may be transmission duration of data, or may be a quantity of times of transmission of data, or may be another parameter that can be detected, for example, traffic. To facilitate understanding, an example is provided as follows: assuming that data of the to-be-detected service is transmitted on the target air interface connection for x times, and total transmission duration is t1, and that data of the another service is transmitted on the target air interface connection for y times, and total transmission duration is t2, and assuming that the connection duration of the target air interface connection is T, according to the exemplary solution provided by this embodiment of the present invention, the air interface duration consumed on the target air interface connection by the to-be-detected service is (x/(x+y))×T or (t1/(t1+t2))×T.
To facilitate understanding, a more intuitive example is provided below:
(1) Assume that T=5 minutes, that is, the connection duration of the target air interface connection is 5 minutes. Within the 5 minutes, the UE initiates 10 flows, where 5 flows belong to an instant chat service, and 5 flows belong to a browse service. It is assumed that the instant chat service is the to-be-detected service. In this case, the detecting apparatus may decompose the connection duration according to a proportion of a quantity of flows of the instant chat service in a total quantity of flows on the target air interface connection, to obtain that air interface duration consumed on the target air interface connection by the instant chat service is 2.5 minutes. If the browse service is the to-be-detected service, the detecting apparatus may decompose the connection duration according to a proportion of a quantity of flows of the browse service in a total quantity of flows on the target air interface connection, to obtain that air interface duration consumed on the target air interface connection by the browse service is 2.5 minutes.
(2) Assume that T=5 minutes, that is, the connection duration of the target air interface connection is 5 minutes. Within the 5 minutes, data of a video service and data of a File Transfer Protocol (File Transfer Protocol, FTP) service are transmitted. It is assumed that transmission duration of the data of the video service is 1 minute, and that transmission duration of the data of the FTP service is 1 minute. If the video service is the to-be-detected service, the detecting apparatus may decompose the connection duration according to a proportion of the transmission duration of the video service in total transmission duration, to obtain that air interface duration consumed on the target air interface connection by the video service is 2.5 minutes. If the FTP service is the to-be-detected service, the detecting apparatus may decompose the connection duration according to a proportion of the transmission duration of the FTP service in total transmission duration, to obtain that air interface duration consumed on the target air interface connection by the FTP service is 2.5 minutes.
A person skilled in the art should understand that, in a case in which the target air interface connection transmits data of the another service, there may be other calculating methods for calculating the air interface duration consumed on the target air interface connection by the to-be-detected service, which is not limited in this embodiment of the present invention.
Exemplarily, after the air interface duration consumed on each target air interface connection in the target air interface connection set by the to-be-detected service is determined, the air interface duration consumed by the to-be-detected service may be obtained. For example, a sum of air interface duration consumed on each target air interface connection in the target air interface connection set is used as the air interface duration consumed by the to-be-detected service. A person skilled in the art may understand that there may be other methods for acquiring, according to the air interface duration consumed on each target air interface connection in the target air interface connection set, the air interface duration consumed by the to-be-detected service, for example, air interface duration consumed on target air interface connections in the target air interface connection set that meet a particular condition is accumulated to obtain the air interface duration consumed by the to-be-detected service, which is not limited in this embodiment of the present invention.
As another optional solution for acquiring air interface resource consumption info Elation of the to-be-detected service, the detecting apparatus 110 may determine a quantity of times of air interface connection consumed by the to-be-detected service.
Exemplarily, after determining the target air interface connection set, the detecting apparatus 110 may determine, according to a situation of consumption of the target air interface connections in the target air interface connection set by the to-be-detected service, the quantity of times of air interface connection consumed by the to-be-detected service.
For example, for each target air interface connection in the target air interface connection set, it is determined, according to the air interface connection information and the service information, whether data that is transmitted on the target air interface connection for the first time is the data of the to-be-detected service; and if the data that is transmitted on the target air interface connection for the first time is the data of the to-be-detected service, it is determined that the to-be-detected service consumes the target air interface connection, and it may be considered that the to-be-detected service consumes the air interface connection once. Alternatively, if the data that is transmitted on the target air interface connection for the first time is not the data of the to-be-detected service, but is data of another service, it may be considered that the to-be-detected service does not consume the target air interface connection. By counting a quantity of target air interface connections consumed in the target air interface connection set by the to-be-detected service, the quantity of times of air interface connection consumed by the to-be-detected service can be obtained. A person skilled in the art should understand that there may be other methods for determining that the to-be-detected service consumes the target air interface connection, for example, if it is determined that transmission duration of the to-be-detected service on the target air interface connection is the longest or exceeds a threshold, it is considered that the to-be-detected service consumes the target air interface connection, which is not limited in this embodiment of the present invention.
To compare air interface resource consumption situations of different to-be-detected services more intuitively, consideration maybe taken as to calculating an air interface resource consumption situation of the to-be-detected service based on unit traffic, for example, air interface duration consumed by unit traffic, or a quantity of times of connection consumed by unit traffic.
Exemplarily, traffic generated by the to-be-detected service may be determined according to the service information. The service information may further include traffic information generated between the time points at which the UE starts and stops transmitting the data of the service. For example, the service information may include the following content: UE ID1, 13:01, video service, start; UE ID1, 13:04, video service, stop; and UE ID1, 13:01-13:04, video service, traffic 10 M. The traffic generated by the to-be-detected service may be total traffic transmitted on all target air interface connections in the target air interface connection set by the to-be-detected service, or maybe total traffic transmitted, by the to-be-detected service, on some target air interface connections in the target air interface connection set that meet a particular condition, or the traffic generated by the to-be-detected service may be directly determined according to a sum of traffic that is transmitted by the to-be-detected service and is recorded in the service information. The traffic generated by the to-be-detected service may specifically be determined by using different methods according to different network requirements, which is not limited in this embodiment of the present invention. After the traffic generated by the to-be-detected service is determined, air interface duration or a quantity of times of air interface connection consumed by unit traffic of the to-be-detected service may be determined according to the determined air interface duration or quantity of times of air interface connection consumed by the to-be-detected service.
In this embodiment of the present invention, according to time points at which a TIE establishes and releases an air interface connection that are collected from a control plane entity, and time points at which the TIE starts and stops transmitting data of a service that are collected from a data plane entity, a target air interface connection transmitting a to-be-detected service can be accurately obtained through matching, so that statistics about a resource consumption situation of the to-be-detected service on the target air interface connection can be collected, which is more accurate than a manual dialing test manner or a probe manner.
In addition, the control plane entity and the data plane entity may separately report the air interface connection information of the UE and the service information of the UE in real time, the detecting apparatus may analyze and determine air interface resource consumption information of the to-be-detected service in real time according to the information reported in real time, which can ensure the real-time quality of a statistical result of air interface resources consumed by the service.
Furthermore, because the data plane entity is implemented by a network element in a live network, types of various services initiated by the UE in the live network can be detected, and therefore statistics about air interface resources consumed by various to-be-detected services can be collected.
The receiving unit 310A is configured to receive, from a control plane entity, air interface connection information of a UE, and receive, from a data plane entity, service information of the UE. The air interface connection information includes time points at which the UE establishes and releases an air interface connection, the service information includes time points at which the UE starts and stops transmitting data of a service, and the service includes a to-be-detected service.
The determining unit 320A is configured to determine a target air interface connection set according to the air interface connection information received by the receiving unit 310A and the service information received by the receiving unit 310A, and determine air interface resource consumption information of the to-be-detected service according to the target air interface connection set. The target air interface connection set includes one or more target air interface connections, and the target air interface connection is an air interface connection transmitting data of the to-be-detected service.
As an optional implementation manner, the determining unit 320A may be configured to determine, for each target air interface connection in the target air interface connection set, resource consumption information of the to-be-detected service on the target air interface connection; and determine the air interface resource consumption information of the to-be-detected service according to the resource consumption information of the to-be-detected service on each target air interface connection in the target air interface connection set.
The following describes in further detail examples in which the air interface resource consumption information is separately used to indicate consumed air interface duration and a quantity of times of air interface connection that is consumed.
(1) A case in which the resource consumption information is used to indicate consumed air interface duration:
Correspondingly, that the determining unit 320A is configured to determine the resource consumption information of the to-be-detected service on the target air interface connection is specifically that: the determining unit 320A is configured to determine connection duration of the target air interface connection according to the air interface connection information; determine, according to the air interface connection information and the service information, whether the target air interface connection transmits data of another service; and if it is determined that the target air interface connection transmits data of the another service, determine, according to transmission consumption of the data of the to-be-detected service on the target air interface connection, transmission consumption of the data of the another service on the target air interface connection, and the connection duration of the target air interface connection, air interface duration consumed on the target air interface connection by the to-be-detected service, where the transmission consumption includes a quantity of times of transmission or transmission duration; or, if it is determined that the target air interface connection does not transmit data of the another service, determine that air interface duration consumed on the target air interface connection by the to-be-detected service is the connection duration of the target air interface connection.
Exemplarily, that the determining unit 320A is configured to determine, according to transmission consumption of the data of the to-be-detected service on the target air interface connection, transmission consumption of the data of the another service on the target air interface connection, and the connection duration of the target air interface connection, air interface duration consumed on the target air interface connection by the to-be-detected service may be specifically that: the determining unit 320A is configured to determine, according to the service information, the transmission consumption of the data of the to-be-detected service on the target air interface connection as C1; determine, according to the service information, the transmission consumption of the data of the another service on the target air interface connection as C2; and determine the air interface duration consumed on the target air interface connection by the to-be-detected service as C1/(C1+C2)×T, where T is the connection duration of the target air interface connection.
In addition, that the determining unit 320A is configured to determine the air interface resource consumption information of the to-be-detected service according to the resource consumption information of the to-be-detected service on each target air interface connection in the target air interface connection set may be specifically that: the determining unit 320A is configured to determine that air interface duration consumed by the to-be-detected service is a sum of air interface duration consumed on each target air interface connection in the target air interface connection set by the to-be-detected service.
To facilitate comparing air interface resource consumption situations of different to-be-detected services, the determining unit 320A may be further configured to determine air interface resource information consumed by unit traffic of the to-be-detected service.
At the same time when the data plane entity collects the time points at which the UE starts and stops transmitting the data of the service, the data plane entity may further record traffic information generated within a period of time from starting to stopping transmission of the service. Therefore, the service information may further include traffic information generated between the time points at which the UE starts and stops transmitting the data of the service. Correspondingly, the determining unit 320A maybe further configured to: determine, according to the service information, traffic generated by the to-be-detected service; and determine, according to the traffic generated by the to-be-detected service and the air interface duration consumed by the to-be-detected service, air interface duration consumed by unit traffic of the to-be-detected service.
(2) A case in which the resource consumption information is used to indicate a quantity of times of air interface connection that is consumed:
Correspondingly, that the determining unit 320A is configured to determine the resource consumption information of the to-be-detected service on the target air interface connection is specifically that: the determining unit 320A is configured to determine, according to the air interface connection information and the service information, whether data that is transmitted on the target air interface connection for the first time is the data of the to-be-detected service; and if the data that is transmitted on the target air interface connection for the first time is the data of the to-be-detected service, determine that the to-be-detected service consumes the target air interface connection once.
Furthermore, if the data that is transmitted on the target air interface connection for the first time is not the data of the to-be-detected service, the determining unit 320A may determine that the to-be-detected service does not consume the target air interface connection.
That the determining unit 320A determines the air interface resource consumption information of the to-be-detected service according to the resource consumption information of the to-be-detected service on each target air interface connection in the target air interface connection set may be specifically that: the determining unit 320A is configured to determine that a quantity of times of air interface connection consumed by the to-be-detected service is a sum of quantities of times of connection consumed on the target air interface connection in the target air interface connection set by the to-be-detected service.
The determining unit 320A may be further configured to determine a quantity of times of air interface connection consumed by unit traffic of the to-be-detected service. Therefore, the service information may further include traffic information generated between the time points at which the UE starts and stops transmitting the data of the service.
Correspondingly, the determining unit 320A may be further configured to: determine, according to the service information, traffic generated by the to-be-detected service; and determine, according to the traffic generated by the to-be-detected service and the quantity of times of air interface connection consumed by the to-be-detected service, a quantity of times of air interface connection consumed by unit traffic of the to-be-detected service.
A person skilled in the art should understand that the control plane entity may include a base station or a base station controller. The air interface connection may include a radio resource (Radio Resource, RR) connection, a radio resource control (Radio Resource Control, RRC) connection, a temporary block flow (Temporary Block Flow, TBF) bearer, or a radio bearer (Radio Bearer, RB). The control plane entity may include a mobility management network element, and the air interface connection includes an Iu/S1 connection. The data plane entity may include a serving gateway or a data gateway.

As shown in
The base station device 420 is configured to implement a function of the control plane entity in
In UMTS, the UE establishes an RRC connection before initiating a service, and releases the RRC connection after data transmission of the service is stopped. An air interface connection may be an RRC connection, and the control plane entity may be an RNC. The RNC may record time points at which the RRC connection is established and released. Furthermore, the air interface connection may also be an RB bearer, and the RNC may record time points at which the RB bearer is established and released.
In an LTE system, the UE establishes an RRC connection before initiating a service, and releases the RRC connection after data transmission of the service is stopped. An air interface connection may be an RRC connection, and the control plane entity may be an eNB. The eNB may record time points at which the RRC connection is established and released. Furthermore, the air interface connection may also be an RB bearer, and the eNB may record time points at which the RB bearer is established and released.

For example, in UMTS, the mobility management network element may be an SGSN. When a UE establishes an RRC connection, the SGSN establishes an Iu connection to an RNC. When the UE releases the RRC connection, the SGSN releases the Iu connection to the RNC. Therefore, the SGSN may record time points at which the Iu connection is established and released, so as to determine time points at which the RRC connection is established and released.
In an LTE system, the mobility management network element maybe an MME. Similar to UMTS, when a UE establishes an RRC connection, the MME establishes an S1 connection to an eNB. When the UE releases the RRC connection, the MME releases the S1 connection to the eNB. Therefore, the MME may record time points at which the S1 connection is established and released, so as to determine time points at which the RRC connection is established and released.

Based on the inventive concept of the foregoing embodiments, an embodiment of the present invention further provides a method for determining air interface resources consumed by a service. The method is not only applicable to the system exemplified in the embodiments of the present invention, but can also be applied to systems of other communications technologies along with the development of technologies.
710: Receive, from a control plane entity, air interface connection information of a user equipment UE, where the air interface connection information includes time points at which the UE establishes and releases an air interface connection.
720: Receive, from a data plane entity, service information of the UE, where the service information includes time points at which the UE starts and stops transmitting data of a service, and the service includes a to-be-detected service.
730: Determine a target air interface connection set according to the air interface connection information and the service information, where the target air interface connection set includes one or more target air interface connections, and the target air interface connection is an air interface connection transmitting data of the to-be-detected service.
740: Determine air interface resource consumption information of the to-be-detected service according to the target air interface connection set.
For content related to the determining air interface resource consumption information of the to-be-detected service according to the target air interface connection set, refer to the embodiments shown in
In this embodiment of the present invention, because time points at which a UE establishes and releases an air interface connection are collected from a control plane entity, and time points at which the UE starts and stops transmitting data of a service are collected from a data plane entity, a target air interface connection transmitting a to-be-detected service can be accurately obtained by matching according to the foregoing time information, so that statistics about air interface resource consumption information of the to-be-detected service can be accurately collected according to a resource occupation situation of the target air interface connection.
Furthermore, there are many service types in a live network, but an existing manual dialing test method only covers limited service types. In addition, with the continuous upgrade of various types of services, it is difficult to ensure the real-time quality of a statistical result.
In this embodiment of the present invention, the control plane entity and the data plane entity can separately report the air interface connection information of the UE and the service information of the UE in real time, the detecting apparatus can analyze and determine air interface resource consumption information of the to-be-detected service in real time according to the information reported in real time, which can ensure the real-time quality of a statistical result of air interface resources consumed by the service.
In addition, because the data plane entity is implemented by a network element in a live network, the data plane entity can perform comprehensive detection on types of services initiated by a UE in the live network, and therefore can cover all types of services in the live network when collecting statistics about air interface resources consumed by a service.
In this embodiment of the present invention, the control plane entity may report air interface connection information of the UE to the detecting apparatus after each air interface connection is released. In this case, the air interface connection information may include time points at which the UE establishes and releases the air interface connection. Correspondingly, the service information of the data plane entity may include time points at which the UE starts and stops transmitting the data of the service on the air interface connection. For example, in step 720, the data plane entity may immediately report the service information of the UE to the detecting apparatus after each data transmission of the service stops. Generally, the control plane entity may report the air interface connection information by using one time of air interface connection establishment and release as a granularity, and the data plane entity may report the service information by using one time of starting and stopping service transmission as a granularity; in this way, the detecting apparatus can determine the air interface resource consumption information of the to-be-detected service more efficiently. For example, one record in the air interface connection information may include a UE identity (Identity, ID), a time point at which the air interface connection is established, and a time point at which the air interface connection is released; and one record in the service information may include a UE ID, a time point at which the UE starts transmitting the data of the service, a time point at which the UE stops transmitting the data of the service, and a service type, and optionally may further include traffic generated by the data of the service. The service type may include a type of a service flow or an application (Application) type. The service type may be obtained by the control plane entity by deep packet inspection.
Furthermore, in this embodiment of the present invention, the air interface connection information and the service information may also be periodically received by the detecting apparatus, and the control plane entity may report the air interface connection information of the UE to the detecting apparatus according to a particular period. In this case, the air interface connection information may include time points at which the UE establishes and releases one or more air interface connections within the period. Correspondingly, the data plane entity may also report the service information of the UE to the detecting apparatus according to the period. And in this case, the service information may include time points at which the UE starts and stops transmitting data of one or more types of services within the period.
Exemplarily, both the control plane entity and the data plane entity may report information according to a preset period, for example, the period may be preset to half an hour. In this way, the air interface resource consumption information of the to-be-detected service determined by the detecting apparatus is air interface resource consumption information of the to-be-detected service within the period.
It can be seen that, in this embodiment of the present invention, a time granularity for collecting statistics about air interface resource consumption can be set according to an actual requirement, thereby improving service management performance.
In this embodiment of the present invention, the air interface resource consumption of the to-be-detected service is determined by using a summation manner, that is, by determining, for each target air interface connection in the target air interface connection set, the resource consumption information of the to-be-detected service on the target air interface connection, and determining air interface resource consumption information of the to-be-detected service according to the resource consumption information of the to-be-detected service on each target air interface connection in the target air interface connection set. In other words, resource consumption information of the to-be-detected service on all the target air interface connections in the target air interface connection set may be separately determined. Then statistics about the resource consumption information of the to-be-detected service on all the target air interface connections are collected, so as to determine the air interface resource consumption information of the to-be-detected service. This manner is simple and efficient to implement. It should be noted that, in this embodiment of the present invention, determining of the air interface resource consumption information of the to-be-detected service is not limited to this manner, and may also be implemented by using another algorithm.
In this embodiment of the present invention, when the target air interface connection set includes one target air interface connection, the air interface resource consumption of the to-be-detected service on the target air interface connection is the air interface resource consumption of the to-be-detected service. When the target air interface connection set includes multiple target air interface connections, the foregoing summation manner may be used.
In this embodiment of the present invention, for determining of the air interface resource consumption of the to-be-detected service on a single target air interface connection, a situation of another service is also considered. That is, according to transmission consumption of the to-be-detected service and the another service on the target air interface connection, air interface duration consumed on the target air interface connection by the to-be-detected service is determined, and therefore accuracy of the air interface resource consumption information of the to-be-detected service can be ensured.
In this embodiment of the present invention, consideration is also taken as to obtaining air interface resource consumption information of unit traffic of the to-be-detected service, for example, air interface duration consumed by unit traffic or a quantity of times of air interface connection consumed by unit traffic, which facilitates comparing air interface resource consumption information of different to-be-detected services, thereby providing a basis for network optimization; and the to-be-detected services may also be classified according to efficiency, for example, a service in which air interface duration consumed per megabyte of traffic is more than one hour may be considered as an inefficient service. For another example, a service in which a quantity of times of connection consumed per megabyte of traffic is more than 100 may be considered as an inefficient service.
