Embodiment 1

[0032] figure 1 A flowchart of an embodiment of a method for locating and paging a black hole cell in the present invention, such as figure 1 As shown, the method may include:

[0033] S101. Every time when the terminal moves from the first cell where it resides to the second cell, the terminal records the correspondence between the identity of the terminal, the information of the second cell, and the time of entering the second cell Relational tables;

[0034]In the GSM / CDMA / TD-SCDMA network, after the terminal is turned on, the first task is to search for a suitable cell to access the network. Firstly, a PLMN selection process automatically or manually selects a Public Land Mobile Network (PLMN), and after the PLMN is selected, cell search within the PLMN starts. Usually, the terminal will read the information of the PLMN and a certain cell stored in the memory before the last shutdown, such as frequency point, scrambling code, etc., and the terminal can use this informat...

Embodiment 2

[0047] An embodiment of the present invention provides a method for locating and paging a black hole cell, such as figure 2 shown, including:

[0048] S201. The server receives the corresponding relationship table of the terminal identifier, the information of the second cell, and the time of entering the second cell, which is recorded each time the terminal moves from the first cell to the second cell, sent by the terminal. ;

[0049] Wherein, the correspondence table includes: the IMSI of the terminal, the time of entering the cell, and the cell number. For convenience of description, the cell where the terminal currently resides is defined as the first cell, and the new cell to which the terminal moves is defined as the second cell. It should be noted that the first cell and the second cell are not two fixed cells, but are only used to distinguish the cell where the terminal currently resides and the new cell to which it moves. For example, if the terminal currently res...

Embodiment 3

[0056] Such as image 3 As shown, in this embodiment, the flow of the method for locating and paging a black hole cell is as follows:

[0057] S301. The terminal records the corresponding relation table among the identifier of the terminal, the information of the second cell, and the time of entering the second cell;

[0058] In the GSM / CDMA / TD-SCDMA network, after the terminal is turned on, the first task is to search for a suitable cell to access the network. Firstly, a PLMN selection process automatically or manually selects a Public Land Mobile Network (PLMN), and after the PLMN is selected, cell search within the PLMN starts. Usually, the terminal will read the information of the PLMN and a certain cell stored in the memory before the last shutdown, such as frequency point, scrambling code, etc., and the terminal can use this information to simplify the cell search process. When a suitable cell is found and camped on, the terminal records the information of the cell cur...

Abstract

An embodiment of the invention provides a method of positioning a paging black hole cell. The method comprises the following steps that when moving from a first cell to a second cell, a terminal records a corresponding relation table of an identification of the terminal, information of the second cell and time of entering the second cell; the recorded corresponding relation table is sent to a server so that the server carries out association analysis on the recorded corresponding relation table and unresponsive call recording after acquiring the unresponsive call recording of network equipment so as to position the paging black hole cell. Correspondingly, the embodiment of the invention also provides a terminal, the server and a system of positioning the paging black hole cell. In the prior art, accuracy of the paging black hole cell positioning is low. By using the method, the apparatus and the system of the invention, the above problem is solved and reliability of a positioning result is increased.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a method, device and system for locating and paging a black hole cell. Background technique [0002] The process of wireless paging, that is, the communication process in which the Mobile Services Switching Center (MSC) finds the mobile station (Mobile Station, MS) through paging. Only after the mobile user is found, the MSC can proceed to the next step. The call continues to work. In the mobile communication system, the basic signaling process of wireless paging is as follows: when the MSC obtains the location area where the MS is currently located from the Visitor Location Register (VLR), it will send a message to all base station controllers in this location area. (Base Station Controller, BSC) sends a paging (Paging) message, and after receiving the paging message, the BSC sends a paging command message (PagingCommand) to all cells belo...
