Detailed Description
at present, when a mobile terminal starts an E-CID function, time for measuring and reading a neighbor system message generally needs to be scheduled by itself, and a base station does not particularly reserve time for measuring and reading a neighbor system message for the mobile terminal. That is to say, the mobile terminal usually suspends receiving the signal of the current serving cell, switches to the frequency point of the neighboring cell, and receives the system message of the neighboring cell according to a certain windowing length and windowing density. Therefore, the situation that the wireless link is out of step due to the fact that the mobile terminal cannot reasonably schedule, measure and read the system messages of the adjacent cells often occurs, and particularly when the mobile terminal receives the system messages one by one at frequency points, the mobile terminal cannot receive or timely receives corresponding information sent by a base station, and finally the wireless link connection of the mobile terminal is failed, or even a call is dropped.
In view of the above problems, embodiments of the present invention provide a method for positioning a mobile terminal, where the method enables the mobile terminal to receive system messages of a current serving cell and an adjacent cell within a preset time period configured by a base station, and further enables the mobile terminal to obtain corresponding positioning information from the received system messages and report the corresponding positioning information to the positioning server when receiving a request for obtaining the positioning information sent by the positioning server, so that the mobile terminal is prevented from being unable to receive or timely receive the corresponding information sent by the base station, and situations of radio link connection failure and call drop occurring when the mobile terminal applies an E-CID function are reduced.
in order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
As shown in fig. 1, an embodiment of the present invention provides a method for positioning a mobile terminal.
The method may comprise the steps of:
And 11, receiving a positioning capability reporting request sent by a positioning server.
In specific implementation, the positioning server may be triggered to send the positioning capability reporting request in various ways, for example, the positioning server may be triggered to send the positioning capability reporting request in a way that the mobile terminal sends the positioning request to the positioning server; the positioning server can also be triggered to send a positioning capability reporting request in a manner that the positioning server sends a positioning request to the mobile terminal. That is, both the positioning server and the mobile terminal may trigger the positioning server to send a positioning capability reporting request.
The mobile terminal may generate the positioning request in various ways, for example, the positioning request may be generated by an application program such as map software of the mobile terminal.
In the embodiment of the present invention, the mobile terminal refers to a computer device that can be used in a mobile process, and includes, but is not limited to, a mobile phone, a notebook, a tablet computer, and a vehicle-mounted computer. The mobile terminal may support two communication modes, or may support three or more communication modes. No particular limitation is imposed on the present invention regardless of the number of communication modes that the mobile terminal can support, and the present invention is within the scope of the present invention.
It should be noted that, in the embodiment of the present invention, the positioning server may be an independent dedicated server, or may provide other services at the same time, for example, a dedicated storage area and a dedicated memory area may be opened on other servers to provide the positioning service. Of course, the positioning server, regardless of the manner in which it is used, may communicate with the mobile terminal.
The mobile terminal and the positioning server may communicate with each other by using a wired connection or a wireless connection. The wireless connection method may include various communication modes such as WiFi, bluetooth, infrared and the like. No matter what the connection mode between the mobile terminal and the positioning server is, the present invention is not limited and is within the protection scope of the present invention.
And 12, reporting the positioning capacity information to the positioning server according to the positioning capacity reporting request.
And when the mobile terminal receives the positioning capacity reporting request, reporting the self positioning capacity to the positioning server. The positioning capability of the mobile terminal comprises the positioning capability of each cell under the current communication system and the positioning capability of each cell under the different system.
In a specific implementation, except for a communication system corresponding to a current communication mode, other communication systems supported by the mobile terminal are all heterogeneous systems. For example, the current communication mode of the mobile terminal is an LTE mode, and the corresponding current communication system is an LTE system. The heterogeneous System may be one or more of Wireless Local Area Network (WLAN), Global System For Mobile communications (GSM), Time Division-Synchronous Code Division Multiple Access (TD-SCDMA), Code Division Multiple Access (CDMA) 2000, and the like.
when reporting the positioning capability information, the mobile terminal can report the positioning capability information of at least one different system besides the positioning capability information of the current communication system. The at least one heterogeneous system may be one of heterogeneous systems supported by the mobile terminal, or two or more heterogeneous systems. In an embodiment of the present invention, the mobile terminal may report the positioning capability information of the current communication system and the positioning capability information of all the different systems.
And step 13, receiving a request for acquiring the positioning information generated by the positioning server according to the reported positioning capability information.
after receiving the positioning capability information sent by the mobile terminal, the positioning server can generate a corresponding request for acquiring the positioning information. For example, when the positioning capability information reported by the mobile terminal includes an LTE communication system and a WLAN communication system, the request for obtaining the positioning information obtains the positioning information related to the LTE communication system and the WLAN communication system.
And step 14, acquiring corresponding positioning information from the system information received in advance according to the request for acquiring the positioning information, reporting the positioning information to the positioning server, and positioning the geographic position of the mobile terminal by the positioning server according to the reported positioning information.
In a specific implementation, the system message received in advance is received by the mobile terminal within a preset time period configured by the base station. That is to say, before the mobile terminal accurately receives the system message, the base station may be notified to configure the receiving time for the mobile terminal, and then the system message may be received according to the receiving time configured by the base station, so that it may be avoided that the mobile terminal cannot receive or timely receives other information sent by the base station, and situations of radio link connection failure and call drop when the mobile terminal applies the E-CID function are reduced.
in particular implementations, the mobile terminal may notify the base station in a variety of ways. In an embodiment of the present invention, the base station may be notified by sending an E-CID measurement request to the base station. The E-CID measurement request may include a communication mode and a frequency point number of a cell corresponding to the positioning information, and a number of cells corresponding to each frequency point. According to the E-CID measurement request, the base station can reasonably set the preset time period. In other embodiments of the present invention, the base station may also be notified by sending other trigger messages to the base station.
In a specific implementation, the base station may send the preset time period information to the mobile terminal in a plurality of ways. In an embodiment of the present invention, the base station may send the preset time period information to the mobile terminal in a manner of a measurement configuration message. The form of the measurement configuration message may be set according to the current communication mode of the mobile terminal. In other embodiments of the present invention, the base station may further send the preset time period information to the mobile terminal by adding a new message. According to the measurement configuration message or the new message, the mobile terminal can acquire the measurement gap of the system message to be received.
it should be noted that, in a specific implementation, the mobile terminal may send an E-CID measurement request to the base station before receiving each system message, or may send an E-CID measurement request to the base station before receiving two or more system messages. That is, the mobile terminal may notify the base station of configuring the receiving time for the mobile terminal before receiving the system message every time, or may notify the base station of configuring the receiving time for the mobile terminal before receiving the system message twice or more. After receiving the E-CID measurement request, the base station may configure, in one measurement configuration message, the mobile terminal with the reception time for receiving all system messages, and may configure, in a plurality of measurement configuration messages, the mobile terminal with the reception time for receiving part of the system messages.
in a specific implementation, the positioning information may include: real-time positioning information and non-real-time positioning information. The real-time positioning information may be obtained by the mobile terminal through cell measurement, for example, signal strength of each cell. The non-real-time Location information may be obtained by the Mobile terminal reading a corresponding system message, for example, Public Land Mobile Network (PLMN), Location Area Code (LAC), Routing Area Code (RAC), Tracking Area Code (TAC), intra-PLMN unique Cell Identity (Global Cell ID), Cell frequency point (freq), physical Cell number (phy Cell ID), and other information. It can be understood that the positioning information of different communication systems is different, and the content of the specific positioning information is not limited as long as the mobile terminal can report part or all of the positioning information under the corresponding system to the positioning server.
in an embodiment of the present invention, the non-real-time positioning information may be obtained from the system message received in advance. When the mobile terminal reports the positioning information according to the request for obtaining the positioning information, on one hand, the non-real-time positioning information can be obtained from the system information received in advance, and on the other hand, the non-real-time positioning information and the real-time positioning information can be reported to the positioning server together through the real-time positioning information obtained by cell measurement.
In a specific implementation, a manner of reporting the positioning information to the positioning server by the mobile terminal is not limited, as long as the positioning server can receive the positioning information. For example, the positioning information may be sent to the positioning server in a signaling manner, or may be sent to the positioning server in an IP data link report manner.
As can be seen from the above, in the positioning method of the mobile terminal in the embodiment of the present invention, the system messages of the current serving cell and the neighboring cell are received within the preset time period configured by the base station, and then when the request for obtaining the positioning information sent by the positioning server is received, the corresponding positioning information is obtained from the received system messages and reported to the positioning server, so that the positioning server can more quickly position the mobile terminal, and the power consumption of the mobile terminal can be effectively reduced.
