The technology of this disclosure relates generally to reliability of a wireless distribution system (WDS), and more particularly to techniques for enhancing quality of service (QoS) and metrics of communication signals which may be used in a wireless distribution system.
Wireless communication is rapidly growing, with ever-increasing demands for high-speed mobile data communication. As an example, local area wireless services (e.g., so-called “wireless fidelity” or “Wi-Fi” systems) and wide area wireless services are being deployed in many different types of areas, e.g., coffee shops, airports, libraries, and the like. Wireless distribution systems (WDSs) communicate with wireless devices called “clients,” “client devices,” “wireless client devices,” or “wired client devices,” which reside within the wireless range or “cell coverage area” in order to communicate with an access point device. More generally, a client is computer hardware or software that accesses a service made available by a server. One example of a wireless distribution system is a distributed antenna system (DAS). DASs are particularly useful for deployment inside buildings or other indoor environments where client devices may not otherwise be able to effectively receive radio-frequency (RF) signals from a source, such as a base station, for example. Exemplary applications where distributed antenna systems can be used to provide or enhance coverage for wireless services include public safety, cellular telephony, local access network (LANs), wireless local access networks (wireless LANs), distributed antenna systems (DAS), location tracking, and medical telemetry inside buildings and over campuses.
Wireless communications services are expanding rapidly into an ever-wider array of communications media. Wi-Fi or wireless fidelity systems, for example, are now commonplace, used in a variety of commercial and public settings, such as homes, offices, shops, malls, libraries, airports, and the like. Distributed antenna systems are commonly used to improve coverage and communication of cellular and Wi-Fi communication systems. Distributed antenna systems typically include a plurality of spatially separated antennas. The distributed antennas systems communicate with a variety of such commercial communications systems to distribute their services to clients within range of the distributed antenna system.
These antenna systems provide efficient distribution of communications services to clients, or a set of client devices, in a desired area of a location, such as a building, an array of buildings or an even larger service area, such as an airport, an outdoor park or a stadium. Within the client area, distribution of the services may be provided by an internal distribution network that is a part of the distributed antenna system. The network may include optical fibers and conventional wired cables for distributing a variety of communications services.
What is needed is a better way to improve Quality of Service (QoS) and QoS metrics in wireless and wired distribution systems.

These communications services can include cellular services, wireless services such as RFID tracking, Wireless Fidelity (Wi-Fi), local area network (LAN), WLAN, and combinations thereof, as examples. The coverage areas 10(1)-10(N) may be remotely located. In this regard, the remote coverage areas 10(1)-10(N) are created by and centered on remote antenna units 14(1)-14(N) connected to a central unit 16 (e.g., a head-end controller or head-end unit).

The wireless service processors 2281 through 228n facilitate communicating application level information received through the communications interface 226 in a wireless distribution system (WDS). The wireless service processors 2281 through 228n also facilitate the client device 200 being able to communicate application level information, wired or wirelessly, to other systems (not shown) outside the wireless distribution system, if desired. Wireless service processors 2281 through 228n may be digital signal processors.
With continuing reference to
The application level information is stored by the processor 212 in the internal memory 222. The power management module 218 of the multiple applications processor 212 manages power consumption in the multiple applications processor to achieve the desired performance levels. The one or more physical communications ports 220 provide wired communications to and from the equipment, if desired. For example, a technician may connect a wired communication device to one of the physical communications ports 220 to retrieve application level information or to load or update application layer applications.

In other embodiments, any computing device containing a multi applications processor configured to execute a mobile application 250 to provide a data service according to this disclosure may be used as the computing device of this disclosure.
The data service 250 comprises the software and hardware that provides for the service previously described.
The head end unit (HEU), optical input unit (OIU), RAUs 1-3, and mobile user equipment 430 operate as previously described in
Multiple application module (MAM) 403 and multiple application unit (MAU) 432 may be located throughout the distributed antenna system (DAS). Advantageously, the multi applications processor of each multiple application module (MAM) 403 and multiple application unit (MAU) 432 is configured to execute a data service according to this disclosure. For example, the multiple application module (MAM) 403 in the HEU/OIU provides a data service from the vantage point of the HEU/OIU where the MAM 403 is located. A provider may call the data service as described in connection with
In the example depicted in
As indicated, each MAM and MAU of this disclosure may be advantageously accessed by a service provider to perform one or more or other specified application processes as explained below. Hence, the service provider can interrogate the MAMs and MAU which may provide data service on the overall Quality of Service (QoS), as well as bit rate and bit error rate of the signal provided by the carrier as explained below. Effectively,
In addition, the network may be extended by deploying MAMs or MAUs beyond the RAU coverage area and networking back to the MAM or MAU in the coverage area of the RAU via wired or wireless interfaces of the client device of the MAM or MAU of this disclosure.
The MAMs or MAUs may be configured as client or master. A client MAM or MAU may automatically detect MAMs or MAUs in its vicinity using different optional communication interfaces and media and configure/change configuration accordingly.
The Wi-Fi capabilities/Bluetooth/wired interface of the user equipment or like equipment of the client of this disclosure may further be used to extend the WDS network. For example, the Wi-Fi hotspot capability of the user equipment or like equipment to a network may allow a client to act as a hotspot external to the RAU. In certain applications, more than one MAM or MAU may serve as a Wi-Fi hotspot client to in the WDS.
Using internal sensors of the user equipment or like equipment, the orientation of the MAM or MAU may be known and used to optimize antenna radiation to achieve communication media optimization. Bluetooth may be used to extend the MAM or MAU deployed network beyond the RAUs to provide extended network for better coverage, capacity and accuracy applications. For example, a MAM at the edge of coverage of an RAU may be used to extend the coverage of the RAU to include the coverage provided by Bluetooth.
Applications running on the MAM or MAU may change over time, periodically or otherwise, to different applications to allow the MAM or MAU to communicate with different components in the network or other MAMs or MAUs. For example, an application on one MAM may switch from hotspot configuration to client and vice versa to enable different communications and networks. Alternatively, more than one application may be running on an MAM or MAU. The applications running on the MAM or MAU may be used to change the cellular backhaul of the MAM or MAU to wired intranet of the WDS. The USB-to-Ethernet to fiber optic network feature of the user equipment or like equipment may be used to extend the network of MAMs and MAUs. Similarly, the USB-to-fiber optic network feature of the user equipment or like equipment may also be used to extend the network.
The internal high processing capabilities and memory of the MAMs and MAUs may be used to share the work load of WDS component modules/units. A MAM or MAU as a network element of the WDS may collect information relevant to specified application process number as previously described by doing the following and executing processes guided by these inputs and prioritization and execution policies. For example, a specified application process may cause the data service to (i) communicate with its internal sensors/processes/events using existing hardware and software methodologies similar to those of the user equipment or like equipment; (ii) consolidate requests from (a) users/appliances within its coverage area (b) from the users/appliances in the WDS coverage area via the network of MAMs and MAUs and form the other relevant WDS network elements utilizing standard communication interfaces on the user equipment or like equipment; (iii) provide for an overall mitigation and consolidation of specified application(s) processes based on the requests from individual users received by the individual MAMs and MAUs; (iv) consolidate relevant requests from the users/events/appliances outside the WDS via relevant communication systems; (v) automatically or otherwise correlate relevant information on the internet and related indoor parameters and corresponding decision making.
For example, a user equipment or like equipment of the client of this disclosure may be used to minimize/optimize electric/battery power consumption by, for example, (i) leveraging the user equipment or like equipment's ‘multi-radio in a single package’ to enable the Wi-Fi, Bluetooth, ZigBee technologies and related networks within the WDS; (ii) continuously charging the stationary MAM or MAU with constant power feed and run power hungry processes via direct electric power feed rather than utilizing the battery; (iii) coordinating scheduling of MAM's or MAU's wireless radio activation/deactivation and processes execution (a) with power usage monitoring and correlation, (b) by delegating the execution load to other MAMs via distributed process execution, (c) by using ‘power utilization-process execution’ emergent knowledge to further refine the prioritization and execution policy, (d) by correlating heat dissipation trends indicated by temperature sensors of the MAM and MAU and their peripherals to processes running on the MAM to extend the battery life and MTBF of the MAM itself; (iv) in case of electric power loss from the constant power feed, activating different execution policies that are designed to minimize the power consumption and execute emergency services only; (v) sharing and extending the work load of WDS component modules/units by utilizing the MAM's and MAU's internal high processing capabilities and memory. Depending on the needs of the application on the user equipment or like equipment, a portion of the hardware and/or software of user equipment or like equipment may be modified or added to enable/add other applications.
Additional embodiments of the MAM and MAU is given in
A further advantage of this configuration is possible and desirable, if both the remote antenna unit and the multiple application module use the same operating system. In this scenario, additional apps and software for the MAM may then be developed by developers using the same software development kit to develop wireless distribution system applications using known techniques and methods. With this focus, centralized application software can be automatically generated or developed for quick adaption to the apps already used in the MAMs. This technique thus leverages existing people, programs and applications for further development and better apps.
Incorporating wireless modules with their greater communications capabilities thus allows manufacturers and users to scale their networks. The network or system is extended by deploying MAMs beyond the remotes in the coverage area and wirelessly networking back to the MAM in the RAU. The MAMs can be configured as client or master and client to automatically detect other MAMs in the vicinity using different optional media and can configure or change configuration accordingly. Such automated correlation with the available information and related indoor and outdoor parameters and corresponding decision making will enable proactive actions rather than reactive actions.
The advantage is that incorporating the MAM into the remote antenna unit, just like incorporating the MAM into the head-end equipment, will make additional applications possible in the wired networks. For example, one would not expect to access wireless services over a typical office or home phone. As discussed above, however, connecting a multiple application module into a remote antenna unit can enable wireless services such as Wi-Fi, Bluetooth® and ZigBee®. Thinking of a multiple application module as a compact supercomputer, e.g., a smart phone, these applications become available and greatly expand and scale-up the choices and options available to users connected to such a system.
One example is the ability to offload Wi-Fi to the (wireless) IP network via the gigabit Ethernet module and the central Ethernet unit. Enabling a MAM to connect to IP network via GEM and CEU would allow for continuous monitoring of the link to IP network and the Wi-Fi connection between the MAM in the RAU and the extensions by test calls. A distinct advantage would be communicating the call metrics with the Wi-Fi offload server. This would allow standard operation of a wired network's quality of service (QoS), with traceability and tracking as well. This is also known as enabling a backhaul capability between an end user and a service provider, such as a cellular telephone network provider.
Another example is creation of a Wi-Fi hot spot using the MAM and the RAU. A Wi-Fi hotspot can be used to create machine-to-machine network communications between MAMs wired to the wireless distribution systems (WDS) and those MAMs that are wirelessly connected to extend the WDS network. Connecting the multiple application module creates a wired connection which may have a higher bandwidth than the wireless connection. By enabling a wired backhaul with a better backhaul bandwidth, the capabilities of the network may be beyond the typical cellular backhaul. Thus, a high-bandwidth Wi-Fi hotspot can be achieved. An additional advantage is that applications running on the MAM can change to different wireless networks (identified by their service set identifier, SSID) to communicate with different clients and networks. Users or equipment can thus switch from hotspot configuration to client and vice versa to enable different communications. Simultaneous operations may also be possible, if there is sufficient bandwidth capability. It should also be clear that using applications running on the MAM, the cellular backhaul of the MAM for Wi-Fi hotspot can be improved. This would provide an ability to monitor and measure spectrum information, e.g., signals, within the wireless distribution system, tracking quality of the service to all served portions of the distribution system.
One embodiment is a communication system as described above, wherein the client device is a peripheral interface port configured to interface a peripheral device to the client device. Another embodiment is the communication system as described above, wherein the client device is a physical communication port configured to allow a physical connection to the client device; another embodiment is the communication device as described herein, wherein the physical communication port is a PoE+ port; another embodiment is the communication device as described herein, wherein the physical communication port is a PoE+ port on the client device, the PoE+ being connected via GEM to the PoE+ on the remote antenna unit (RAU).
Additional options of leveraging existing systems will become apparent with the disclosure of
For instance, a provider may request the data service on MAM 603 to establish a communication with a service being provided by the RDC 609 to determine the QoS of that service. In so doing, the data service could employ the call origination application on the MAM to place the call to a receiver in the RDC. The RDC would have an application that would allow such a call to be made and processed. The data service on the MAM would then receive the service using the call reception application on the MAM. An application on the MAM, such as a data application, could do a QoS analysis of the signal such as determining its power level, error bit rate, etc. The data service could then employ either the Short Message Service (SMS) texting or Instant Messaging (IM) of the MAM to send the requesting provider the details of the analysis. The MAM could communicate the results to a web portal and may export the results to a social media website using a social media application. The analysis of the data could be formatted, manipulated and reported to the requesting provider via a word processing application on the MAM. The report could be provided via an email application on the MAM.
The provider may make additional requests to the MAM using the applications available on the MAM. For instance, the provider may request the MAM to take a picture of the RDC 609 with which it is located to allow a provider to verify the physical integrity of the RDC. The MAM 603 may be requested to take a video using a video application on the MAM and then play the video back using the video playback application for some purpose. For instance, the MAM may take multiple videos and play back one video feed at a time to extract data from each feed to then report back to the provider. The MAM may provide the provider with one or more video streams as part of any reporting operation.
The hands-free mode of a utility or like application may be used by the provider in a number of ways. For instance, the hands free mode detects the presence or absence of a connection (typically the hands free device). In this disclosure the hands-free mode of operation may be used to detect the presence of absence of a connection. For instance, the connection or no connection of various settings in the RDC may be emulated by the hands free application of the MAM to alert the provider making a request of the settings in the RDC.
In other embodiment, the presence application of the MAM may be used to indicate the presence or non-presence of a connection in the RDC. A voice command mode may allow a provider to make requests and receive reports from the MAM using voice commands.
In one example, a provider may be interested in the quality of a gaming application provided on a service. Using this disclosure, the data service may access the service and access the gaming application provide by the service. The provider may then perform tests on the QoS of the gaming service, for example, with bit checks done on the gaming service provided. Alternatively, the provider may interact with the game service in real time by playing the game using the data service of the MAM. Similarly, a provider may request the MAM to download a stream of music. The data service may then employ the music playback application of the MAM to play the music to the provider in real time. Alternatively, the music feed may be sent to the provider using the previously described reporting mechanisms for the provider to do further analysis.
In many of the foregoing examples, the reporting by the MAM is illustratively performed in response to a request by a provider. Alternatively, a provider might subscribe to the data service of the MAM in order to have the MAM provide such reports to the provider automatically on the occurrence of an event or periodically. In this way, a provider may receive reports from a MAM without the need for making requests.
It is thus seen that the applications that are available on a user equipment or like equipment may be advantageously employed according to this disclosure to generate data on a wireless distribution system and improve the QoS of the WDS. Further the platform provided by the user equipment or like equipment advantageously lends itself to widespread application development to leverage the foregoing and other applications for specific applications. Examples of illustrative applications are described later below
A more expansive view of network possibilities is disclosed in the wireless distribution system (WDS) of
The system of
For example, any of the remotes can use the Wi-Fi hotspot capability of the mobile user equipment to network with the MAMs external to the remote units with the latter acting as Wi-Fi clients. For certain applications, external MAMs such as 717, 721, 723, can create Wi-Fi hotspot to which MAMs in remote units, such as 719, 725, 731 and other wired components of the WDS can join as clients. The system can also achieve communication media optimization by optimizing antenna radiation. This can be accomplished by knowing the orientation of an MAM using internal sensors of the MAM. In a similar fashion, the MAMs can use Bluetooth® to extend the MAM network beyond the remote units 715, 719 to provide extended network for better coverage, capacity and accuracy applications. For example, applications running on the MAM may change to different IDs transmitted periodically to communicate with different clients and networks. MAMs can switch from hotspot configuration to client and vice versa to enable different communications and networks. The remotes and intermediate equipment, as well as the head-end equipment, can use applications running on the MAM to change the cellular backhaul of the MAM to wired intranet of the WDS.
Other advantages include using a USB or micro-USB-to-Ethernet to fiber optic network to extend the MAM network and using a USB or micro-USB-to-fiber optic network to extend the MAM network. There are many additional possibilities, such as sharing workloads and collecting service information. Capacity steering may be used to improve traffic on the network. For example, location-based information from one or more multiple application modules may be used to gauge traffic density and whether capacity can be increased by switching some users to different bands. It may also be determined that a permanent increase in capacity is needed. An example would be a network whose traffic is sufficiently dense and slow that a cable upgrade may be needed, e.g., to a larger cable or to a high capacity fiber-optic cable.
Using the techniques described herein, one can monitor traffic on the wireless distribution system. It is then possible to use one or more of the multiple application modules to scan available or used bands and the quality of service in the various bands and services provided. For example, the common pilot channel (CPICH) can be used to determine which bands are more-used or less-used and which bands may be better for quality of service at a given time. The collected information, such as CPICH and similar, may be used for SON (self-organized network) applications and MACRO seepage information and adjustment.
Some of the advantages of the present disclosure may be seen in
Head end equipment 805, including head-end unit 807 and optical input unit 827, is equipped with multiple application modules 817, 819 in the manner discussed previously in this disclosure. Using the multiple application modules 817, 819, the carrier 831 is able to interrogate the head-end equipment. The carrier may also use multiple application unit 833 to communicate with the head-end equipment 805 through multiple application modules 817, 819 to obtain further data on the WDS. For instance the data service of MAU may in response to a request from an MAM 817 or from the provider (such request is not shown) employ the data service of MAM 827 to obtain data on the RDC 823 or to communicate with cloud server 835 or carrier 831. The manner in which a data service is requested and the response of the data service in response to achieve the foregoing and other data metrics and intelligence on WDS occur as previous described.
The data from multiple application modules 817, 819 may also be available through the Internet to a cloud-based service 835, such as a file backup service or files intended for the carrier 831. Without the multiple application modules, the back haul routes discussed above are not available. With the multiple application modules, the carrier is easily able to send information back and forth, including identification information of the end-users and data on the performance of the system, including the quality of the calls or other communication services provided.
In addition to communicating directly with the service providers or carriers 901, the multiple application units 905 can communicate indirectly, and perhaps more conveniently, using the Internet and a cloud server 907 that is available to the multiple application units 905, almost regardless of their location; but with location-based services, able to report on their location as well as their service.
In
The architecture of wireless distribution system 1201 as part of a network 1200 is useful in sharing the workload of the WDS components. This structure is useful in sharing the work load of WDS component modules or units 1213 external to the MAM by utilizing the MAM's internal high processing capabilities and memory. By acting as an element of the network 1200, the multiple application module 1203 collects information relevant to the application or task at hand in several ways to follow processes and execute processes and actions, while guided by the inputs and by the prioritization and execution policies 1205. Multiple application module 1203 communicates with its internal sensors/processes/events 1207 using existing hardware and software in methodologies similar to those of a mobile user equipment. Module 1203 also consolidates requests from the users and applications within its coverage area, and also from the users and applications in the coverage area of the wireless distribution system 1201. Module 1203 accomplishes these tasks with the network of MAMs with which it is in communication, utilizing standard communication interfaces of the module.
Just as module 1203 includes a prioritization and execution policy, additional multiple application modules in the network of MAMs will include their own prioritization and execution policies, such as guidelines for assisting other modules in the network. The guidelines for the MAMs may include an overall mitigation and consolidation application based on the requests from individual users received by the individual MAMs, including module 1203. The guidelines will assist in consolidating relevant requests from the users, events and applications, even from those outside the wireless distribution system 1201 via relevant communication systems, e.g., the internet 1210. The guidelines will assist in automated correlation of the relevant information from all sources, including the Internet, with related local parameters and corresponding decision making.
Another example of such a distributed system is depicted in
In one embodiment, in the communication system as described above, the mobile application includes an instance that provides management of heat dissipation of a location, the sensor is a temperature sensor; and the multi applications processor is configured to execute the instance to provide management of heat dissipation of a location based on data from the temperature sensor.
Power consumption monitoring is important not only for the module itself, but for the processes and devices it may control or monitor. Thus, if the module itself includes a temperature sensor, at least its own temperature, a first indication of power consumption, can be monitored. The module may also be within Bluetooth® or ZigBee® range of a device or a process whose power consumption or temperature is being monitored or controlled using the module. The remote process, its temperature and its power consumption may be monitored and reported by the module. Action may be taken if the process or the temperature or the power consumption goes out-of-bounds.
In some locations, there may be no power available except for batteries, with no means available for recharging the batteries. In other locations, power may be available to operate the equipment or to recharge the battery or batteries, but it may still be desirable to minimize power consumption. One option, if power is available, is to continuously charge the stationary module 1301 with a constant power feed and to run power-hungry processes via direct electric power feed rather than utilizing the battery. Other options available may include scheduling the activation and deactivation times of the module, and if possible, timing the execution of the various processes to be performed by the module. For example, if the site is subject to time-of-day surcharges, it may be possible to schedule battery recharging at night, when rates are lower. Even if the site and the module must be active during high-surcharge times, it may be possible to re-charge when rates are lower, or when additional power is available. While charges for one site may be small, the charges, and possible savings, may be significant for a large network with a plurality of sites.
Power consumption may also be minimized by monitoring power usage and correlating with other modules in the network and by delegating the execution load to other modules via distributed process execution. It may also be possible to use “power utilization-process execution” emergent knowledge to further refine the prioritization and execution policy. It is also possible to monitor the temperature of the heat sink(s) of the module and to correlate heat dissipation trends indicated by temperature sensors of the module and its peripherals to processes running on the module. At a minimum this may be a clue to power consumption and may help to extend the battery life and the mean time between failures (MTBF) of the module itself.
One possible control process for monitoring power consumption is depicted in
In the illustrative embodiment, the control process is for monitoring power consumption. However, it will be appreciated that similar control processes may be implanted to perform other tasks within a network. In addition, any prioritization execution policies used in connection with these processes and the frequency of their updates is a matter of design choice.
For example, another embodiment is a communication system as described above, wherein the mobile application includes an instance that provides management of signals from a base station based upon GPS coordinates, the sensor is a GPS sensor, and the multi applications processor is configured to execute the instance to provide management of signals from a base station based on data from the GPS sensor. Alternatively, position coordinates, such as GPS coordinates, for example, may be manually entered. Another embodiment is a communication system as described above, wherein the mobile application includes an instance that provides tracking of emergency equipment and the multi applications processor is configured to execute the instance to provide tracking of emergency equipment. Another embodiment is the communication system as described above, wherein the mobile application includes an instance that manages power consumption by the client device, the instance being configured to toggle a power feed to the client device between a power source and a battery.
In another embodiment, the mobile application includes an instance that: monitors a predetermined event; detects a predetermined parameter; and manages the predetermined event based upon the detected predetermined parameter
In general, the multiple application modules disclosed herein are useful for sharing and extending the work load of wireless distribution systems by utilizing the high processing capabilities and memory of the modules. Smart phones are sufficiently smart that their computing and communications capabilities are underutilized. The present disclosure show how to utilize the multiple wired and wireless media connections of a mobile user equipment, such as a smart phone, to provide redundant backhaul options. Backhaul refers to the ability of a network to send data from end users to the network backbone. It may also refer to the use of wireless communications to transport data from an end user to a node in a major network, such as the Internet or a proprietary communications network, e.g., a large company, academic institution or a government agency. This enables the network to reach out and monitor quality of service (QoS) to the end user, e.g., data concerning the bit rate and bit rate errors.
This ability helps network providers to achieve network robustness by enabling multiple back-haul options on the module namely, Wi-Fi, Bluetooth®, ZigBee® and the cellular network of the mobile user equipment. Useful connectors may include a USB-to-fiber connector, or a micro-USB-to-fiber, or other connector, in order to use the module's USB or similar communication port. The backhaul application on a multiple application module continuously monitors different backhauls and routes traffic via the best option as guided by the “priority and execution policy” discussed above, and routes the traffic accordingly. This capability can help carriers to maintain a high quality of service to end users who previously did not have an available backhaul route.
Other uses also attach to the modules disclosed herein. Depending on the needs of the users for a (stationary) multiple equipment module, a part of the hardware and software may be modified or added to enable or to add non-mobile applications. These may include emulation and simulation, e.g., mobility, using the GPS sensing and location sensing capabilities of the module. Another example may be leveraging GPS sensor-generated x, y, z coordinates of the module or similar x, y, z coordinates. In this example, either system-generated or manual entry of a location may be used to locate other multiple application modules, multiple application units and the wireless distribution system components they are associated with. This information may be used for context generation and communication.
As discussed above, using GPS sensors and having an ability to locate a given device or multiple application module in real time is of course useful in delivering location-based services. A service provider may be identified and a better service provider may be located using automatic SSID (service set identifier) identification and coding. Multiple application modules may include multiple wireless interfaces for hosting a plurality of location-based services. The multiple application modules of the present disclosure will unobtrusively collect user equipment (module) location information, e.g., the x, y, z coordinates mentioned above, from one or more location-based services running on the module(s).
This may also be useful in enabling correlation or tracking of one or more carriers that provide service to the system. Present mobile user equipment is able to receive telephone calls from multiple carriers and connect with multiple carriers in making calls. Using this technology as a stationary multiple application module or a mobile multiple application unit, its GPS locating capability enables carrier correlation with user location. Thus, user equipment performance to a remote wireless distribution system can be quantified. It is also possible to adjust the performance of the wireless distribution system using industry standards that apply to user equipment, such as smart phones. These adjustments may use industry-standard communication protocols and industry-standard communication interfaces. By enabling access to different communication media supported by the multiple application module, a carrier or provider can utilize built-in redundancy to control the wireless distribution system and the downstream distributed antenna system (DAS).
In another embodiment, the first interface is further configured to store the selected network performance in the memory 222 and/or 224 and the second interface is further configured to allow remote access to the selected network performance data stored in the memory.
The selected network performance data acquired by the first interface 1620 illustratively includes data on a signal that may indicate Quality of Service (QoS). For example, the data may include data on the band on which the user equipment 200 is operating. The data may include signal strength, signal quality, bit rate and bit error rate of the signal. The data may also include data on other signals that the user equipment 200 may scan when tuning to a channel for communication. The data to be selected may be determined by a carrier, a provider, a third party, or the like.
The remote access interface 1630 may include remote access user configuration data associated with the user equipment 200. The remote access user configuration data restricts users who may remotely access the selected network performance data to authorized users, such as a service carrier, a provider, or other authorized parties. Illustratively, the configuration data may be set in the user equipment at the point of sale of the user equipment. For example, a user may agree to have such configuration data programmed into the user equipment as part of a contract for service. Alternatively, a user may download an application for the data service and set user permissions for remote access as part of the download, registration, and/or during use of the application. In this and other ways, the remote access interface 1630 manages data traffic it allows to the user equipment.
Remote access to the selected network performance data may be wirelessly via the wireless service processor 228. Alternatively, the remote access to the selected network performance data may be via the peripheral interface port 214.
In the embodiment wherein the first interface is further configured to store the selected network performance in the memory 222 and/or 224 and the second interface is further configured to allow remote access to the selected network performance data stored in the memory, it is advantageous for the stored data to be correlated to the user equipment.
Advantageously, the unique identifier associates the network performance data to some attribute of the user equipment which may be the user equipment itself, a GPS location, a base station tower, or some other network parameter that defines the user equipment at the point of the acquired data. Any data that is remotely exported from the user equipment may carry an origination stamp of the user equipment such as the cell number of the user equipment. Alternatively, the data may carry an origination stamp of a GPS location, a base station tower, an access point, or some other attribute that the data is associated with. Any combination of these or other origination stamps may be associated with the data to allow the network to better manage exported data taken from a network of user equipment.
To enable the functionality described, the instance of the data service configured with the first interface and the second interface would need to be downloaded onto the user equipment. As previously explained, the instance may come with the user equipment on purchase or be downloaded to the user equipment at a later time. In addition, remote access permission configurations may illustratively be set at the point of sale or subsequently as part of the download installation or operation of the application.
When the utility equipment 200 is operating, data is sent and received across the communication interface 226. As shown in
The second interface 1630 provides the remote access to the acquired network performance data by either the carrier 901 or the cloud server 907 in this illustrative embodiment provided that the carrier 901 and the cloud server 907 have the permissions required by the user equipment configuration data to remotely access the acquired network performance data.
Access by the carrier 901 or the cloud server 907 or through the peripheral interface port 214 may occur in real time. The remote access may occur by polling the user equipment. For example, the remote wireless access may occur by polling of the second interface by the server. The polling of the second interface by the server may occur at a predetermined period of time.
In addition, the second interface may be further configured to provide a scheduled uploading of the selected network performance data stored in the memory to the server. Further, the second interface may be configured to download from the server updates to the second interface. Moreover, the second interface or another instance may be configured to install the downloaded updates on the user equipment.
As shown in
In one illustrative embodiment, user equipment 1920 is communicating wirelessly with the network as shown by communication links depicted in dashed line in
In
In either and other examples, the selected network performance data may include data on a signal that may indicate Quality of Service (QoS). For example, the data may include data on the band on which the user equipment 200 is operating. The data may include signal strength, signal quality, bit rate and bit error rate of the signal. The data may also include data on other signals that the user equipment 200 may scan when tuning to a channel for communication. The data to be selected may be determined by a carrier, a provider, a third party, or the like.
In either and other examples, remote access of the selected network performance data may be wirelessly via a wireless service processor. Alternatively, the remote access may be via wire using the peripheral interface port 214.
