Description

A method, device and system for locating and paging a black hole cell

technical field

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

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 belonging to the location area under the BSC. When the base station receives the paging command, it will send a paging request message (Paging Request) on the paging subchannel of the paging group where the International Mobile Subscriber Identity (IMSI) of the wireless channel is located. The message carries the IMSI or temporary mobile subscriber identity (Temporary Mobile Subscriber Identity, TMSI) number of the paged user. After receiving the paging request message, the MS requests allocation of an independent control channel SDCCH through a random access channel (RACH). After confirming that the base station has activated the required SDCCH channel, the BSC assigns the SDCCH channel to the MS through an immediate assignment message on the access grant channel AGCH. The MS uses the SDCCH channel to send a paging response message (Paging Response). The BSC forwards the paging response message to the MSC to complete a successful radio paging.

The success rate of wireless paging is an important network quality indicator of GSM/CDMA/TD-SCDMA network, which directly affects the quality of other network quality indicators such as call connection rate and system connection rate. Good paging performance is very critical for all mobile phone users to be able to make calls successfully.

However, due to the change of wireless network coverage and wireless environment, the uncertainty of the location of mobile users, and the signaling process and mechanism adopted by wireless paging, it is difficult to find the wireless paging black hole (Black Hole) existing in wireless network coverage. become more difficult. Therefore, it is more and more important to find out the wireless paging black hole and optimize the corresponding network, and to evaluate the paging performance at the user cell level in a real-time, comprehensive and effective manner to optimize the mobile communication network.

In the prior art, the A interface signaling of the network device can be collected, analyzed and decoded by the server, and call records are associated and generated, and entered into the database. For example, the paging failure event can be taken as the origin, and the event cell of one minute or five minutes before and after can be traced back to obtain the paging black hole cell list. If the paging success rate of the cell list in the cell list is lower than the set value, it is defined as paging. Black Hole District. The paging black hole cell analyzed by the prior art belongs to the suspected paging black hole cell, the accuracy is low, and the result is unreliable.

Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Embodiment one of the present invention:

Fig. 1 is a flowchart of a method embodiment of positioning and paging a black hole cell according to the present invention. As shown in Fig. 1, the method may include:

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;

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 currently camped on. When the terminal moves in standby mode, it may leave the coverage of the cell it is currently camping on and enter a new cell. At this time, the terminal needs to leave the original cell and re-determine the camping relationship with the new cell. The terminal uses the cell reselection mechanism to complete the selection of a new cell. For the convenience of description, the cell where the terminal 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 resides in cell A and moves to cell B after 5 minutes, the first cell is cell A and the second cell is cell B; if the terminal moves from cell B to cell C after 5 minutes, the first cell The cell becomes cell B, and the second cell becomes cell C. Every time when the terminal moves from the first cell to the second cell, the terminal records the correspondence table of the terminal's identity, the information of the second cell, and the time of entering the second cell, that is, the terminal records the correspondence between the B cell and the terminal A relationship table and a corresponding relationship table between the C cell and the terminal. The identifier of the terminal is the International Mobile Subscriber Identity IMSI, and the information of the second cell is the number of the second cell.

The terminal records the corresponding relationship table of the terminal's identity, the information of the second cell, and the time of entering the second cell. Specifically, it can be realized by installing a third-party recording software, or it can be realized in other ways, and the embodiment of the present invention is not limited . In the process of recording the correspondence table, the cell information where the terminal resides may be collected in real time, and once the terminal changes from the first cell where it resides to the second cell, it records the correspondence table. The recorded information is shown in Table 1:

serial number IMSI Time to enter the community District number 1 460131109000228 2012/4/23 15:20:00 1100 2 460131109000228 2012/4/23 16:10:00 1101 3 460131109000228 2012/4/23 17:20:00 1102 4 460131109000228 2012/4/23 17:30:00 1200

Table 1

S102. Send the correspondence table of the record to the server, so that after the server acquires the non-response call record of the network device, perform correlation analysis on the correspondence table of the record and the non-response call record, and locate Paging the black hole community.

The terminal collects the information of the second cell, and may send the recorded correspondence table to the server at regular intervals. The terminal can directly send the corresponding relationship table recorded during this period to the server, or can first send the corresponding relationship table recorded during this period to a third-party device, and then send it to the server through the third-party device. method is not limited.

During a call, the network device will associate and generate call detail records (Calling Detail Records, CDR). In the embodiment of the present invention, the network device may be a signaling monitoring system composed of monitoring servers. A CDR is a database record containing data about a particular call, used to create billing records, and contains various details such as called and calling parties, originating switch, terminating switch, call duration, occurrence time etc. Through the further analysis and processing of some important parameters in the records, it can provide the basis for analysis for fixed telephone network or mobile telephone network services. The server obtains the paging non-response call record of the network device. Specifically, it can send a request to obtain the paging non-response call record to the network device. After receiving the request, the network device sends the non-response call record to the server, or it can be initiated by the network device. Send the CDR to the server, and the server screens out non-response call records. The unresponsive call record includes the IMSI of the unresponsive terminal, the first paging time, the paging end time, and the location area number of the unresponsive terminal, as shown in Table 2:

Table 2

It should be noted that, as can be seen from Table 2, the unresponsive call records of the network equipment can only go to the location area level. In the GSM/CDMA/TD-SCDMA network, the coverage of the location area is usually larger than the coverage of the cell. Therefore, it is impossible to draw which cell is a paging black hole cell simply from Table 2.

After the server obtains the record correspondence table of the terminal and the non-response call record of the network device, the specific paging black hole cell can be located through correlation analysis. The server uses the IMSI of the non-responsive terminal in the non-response call record, the first paging time, and the paging end time as parameters, queries the corresponding relationship table of the terminal record, obtains the cell location number matched by the parameter, and the cell location number matched by the parameter That is, the located paging black hole cell. The specific method of obtaining the location number of the cell whose parameter matches can be: when the first paging time and the paging end time are both within the period from the time when the terminal enters the first cell to the time when the terminal enters the second cell, or when the first paging time When the paging time is equal to the time of entering the first cell, the first cell is the located paging black hole cell, and the server obtains the number of the first cell to complete the operation of locating and paging the black hole cell. For example, in Table 1, the serial number 2 is recorded as: the terminal whose IMSI is 460131109000228 resides in the cell number 1101 at 16:10:00 on April 23, 2012; in Table 2, the serial number 4 is recorded as: the terminal whose IMSI is 460131109000228 The terminal failed to call during the period from 16:10:00 on April 23, 2012 to 16:10:10 on April 23, 2012, and the current location area number is 460001114. Then the server can locate that in the location area numbered 460001114, the cell numbered 1101 is a paging black hole cell, if the record number 2 in Table 1 becomes: the terminal with IMSI 460131109000228 at 16:09 on April 23, 2012 :50, the number of the resident cell is 1101, and the cell numbered 1101 is also a paging black hole cell.

In the method for locating and paging a black hole cell provided by this embodiment, the terminal records the identity of the terminal after moving to the second cell, the information of the second cell, and the corresponding relationship table of the time of entering the second cell, and sends it to the server, The server collects the non-response call records sent by the network equipment, and locates the paging black hole cell by associating and analyzing the correspondence table of the terminal records and the non-response call records of the network equipment. The problem of low accuracy in positioning and paging black hole cells in the prior art is solved, and the reliability of positioning results is improved.

Embodiment six of the present invention:

An embodiment of the present invention provides a system for locating and paging a black hole cell, as shown in FIG. 6 , including a terminal and a server, wherein,

The terminal 601 is configured to record the identity of the terminal, the information of the second cell and the time of entering the second cell each time the terminal moves from the first cell where it resides to the second cell The corresponding relationship table of the three, sending the corresponding relationship table of the records to the server, so that after the server obtains the non-response call record of the network device, it performs the corresponding relationship table of the record and the non-response call record. Correlation analysis to locate the paging black hole cell;

Wherein, the information of the cell to which the terminal moves includes the IMSI of the terminal, the time of entering the cell, and the serial number of the cell. For the convenience of description, the cell where the terminal 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 resides in cell A and moves to cell B after 5 minutes, the first cell is cell A and the second cell is cell B; if the terminal moves from cell B to cell C after 5 minutes, the first cell The cell becomes cell B, and the second cell becomes cell C.

The server 602 is configured to receive the identity of the terminal, the information of the second cell, and the information of entering the second cell that are recorded each time the terminal moves from the first cell to the second cell and sent by the terminal.

After receiving the corresponding relationship table sent by the terminal, the server needs to obtain the paging non-response call record of the network device. Specifically, it can send a request to obtain the paging non-response call record to the network device. After receiving the request, the network device will record the non-response call The CDR may be sent to the server, or the network device may actively send the CDR to the server, and the server screens out non-response call records.

After the server obtains the record correspondence table of the terminal and the non-response call record of the network device, the specific paging black hole cell can be located through correlation analysis. The server uses the terminal's IMSI, first paging time, and paging end time in the non-response call record as parameters, queries the corresponding relationship table of the terminal record, and obtains the cell location number matched by the parameter. The cell location number matched by the parameter is The located paging black hole cell. The specific method of obtaining the location number of the cell whose parameter matches can be: when the first paging time and the paging end time are both within the period from the time when the terminal enters the first cell to the time when the terminal enters the second cell, or when the first paging time When the paging time is equal to the time of entering the first cell, the first cell is the located paging black hole cell, and the server obtains the number of the first cell to complete the operation of locating and paging the black hole cell.

In the system for locating and paging a black hole cell provided in this embodiment, the terminal records the correspondence table of the identifier of the terminal after moving to the second cell, the information of the second cell, and the time of entering the second cell, and The server collects the unresponsive call records sent by the network equipment, and locates the paging black hole cell by analyzing the correspondence table recorded by the terminal and the unresponsive call records of the network equipment. The problem of low accuracy in positioning and paging black hole cells in the prior art is solved, and the reliability of positioning results is improved.
