Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments, but not all embodiments, of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 2 is a schematic flow chart of a method for guaranteeing continuous adsorption of terminals in a dense group according to an embodiment of the present invention, as shown in fig. 2, including:
201. acquiring target International Mobile Subscriber Identity (IMSI) information of an adsorption terminal through a reselection process;
202. when the terminal needs to be released, sending an NAS message carrying a rejection reason value #10 to the terminal, so that the terminal measures the co-frequency cells of the current cell of the monitoring equipment based on the rejection reason value #10, and determines a target cell meeting an access condition to be adsorbed on the monitoring equipment corresponding to the target cell again.
It should be noted that the execution subject of the embodiment of the present invention is a monitoring device, and the application environment of the embodiment of the present invention is applied to a dense networking, in which a terminal cannot be effectively adsorbed according to the method provided by the prior art. For example: assuming that 2 sets of 4G monitoring devices are networked and the terminal is captured in one of the devices, the monitoring device will issue a reject cause value #13 or a cause value #15 to release the terminal by adopting the scheme of the prior art. After receiving the cause value, the terminal adds a tac (tracking Area code) value to the TAI forbidden list, and does not measure the cell of the frequency point within 300 s. Therefore, the terminal cannot be captured again when moving to the next station in the time period, and the motion track of the terminal cannot be accurately judged.
In step 201, in the embodiment of the present invention, during the process of performing terminal adsorption, the detecting and controlling device captures IMSI information of the terminal in a reselection manner. It can be understood that, after the terminal resides in the public network, the frequency point measurement of the monitoring equipment with higher priority than the serving cell is constantly kept, and reselection is initiated to the monitoring equipment cell after the condition is met, so that connection is established and adsorption is completed, and the IMSI information reported by the terminal can be received after the terminal is adsorbed.
Further, it can be understood that, when the terminal is far away from the cell or needs to release the terminal in the cell for other reasons, the snooping device issues the NAS message from the network side. The embodiment of the invention carries the delivered NAS message as a rejection reason value # 10. It should be noted that, according to the 3GPP protocol, the rejection cause values sent by the core network are different in different scenarios, and the terminal has different behaviors after receiving the NAS rejection cause values. For the rejection reason value #10, the terminal measures the co-frequency cell of the current cell of the monitoring equipment, determines a target cell meeting the access condition, and adsorbs the target cell again on the monitoring equipment corresponding to the target cell. In essence, the terminal provided in the embodiment of the present invention performs the same-frequency reselection after receiving the NAS message carrying the reject cause value #10, that is, the frequency point of the cell of the monitoring device is consistent with the frequency point that resides before the target is adsorbed.
Compared with the prior art, the embodiment of the invention adopts the rejection reason value #10 in the dense networking environment, and adopts the rejection reason value #13 in the prior art, so that the problem that 300s cannot be adsorbed again when the rejection reason value #13 is adopted can be solved by adopting the rejection reason value #10, and the effect of continuously adsorbing the terminal can be achieved. Meanwhile, for the rejection cause value #10, the embodiment of the invention adsorbs the rejection cause value in a common-frequency reselection mode, while in the prior art, the adsorption rate of the network is often improved by using different cell frequency points of the monitoring equipment, but in the scheme of the prior art, the terminal is continuously adsorbed by the monitoring equipment, so that the terminal network is poor, and even has no service. This does not occur with the same frequency reselection.
Therefore, the method for ensuring the continuous adsorption of the terminal in the dense group provided by the embodiment of the invention can ensure the continuous adsorption of the terminal and has small influence on the quality of a terminal communication network by adopting the reject cause value #10 and a same-frequency reselection mode.
On the basis of the above embodiment, before the obtaining of the target international mobile subscriber identity IMSI information of the adsorption terminal through the reselection procedure, the method further includes:
the rejection reason value sent by the network side is locally modified from #13 to # 10.
As can be seen from the content of the foregoing embodiment, in the embodiment of the present invention, when the terminal is released, the NAS message sent by the snooping device carries the reject cause value # 10. It can be understood that, in the prior art, for the reject reason value carried in the NAS message when the terminal is released is generally #13, in essence, in the embodiment of the present invention, before obtaining the IMSI information, the local snooping device needs to modify the issued command value on the network side through a program code, and modify the reject reason value from #13 to # 10.
On the basis of the foregoing embodiment, the acquiring, by a reselection process, the target international mobile subscriber identity IMSI information of the adsorption terminal includes:
receiving a connection establishment request sent by the terminal after the local signal strength meets the reselection condition;
according to the connection establishment request, sending access permission information to the terminal so that the terminal can reply access completion information;
receiving the access completion information replied by the terminal, and sending NAS information carrying the IMSI information to the terminal;
and receiving the IMSI information reported by the terminal.
Specifically, the IMSI information acquisition process provided in the embodiment of the present invention includes the following steps:
1. when the terminal resides in the public network, the frequency point measurement of the monitoring equipment with higher priority than the serving cell is kept all the time;
2. and when the signal strength (RSRP) of the monitoring equipment measured by the position of the terminal meets the reselection condition, the cell of the monitoring equipment is reselected. Initiating a connection establishment request (RRCConnectRequest) to the intercept equipment during reselection;
3. the monitoring device issues an RRCConnectSetup message for the connection establishment request, which indicates that the terminal can access.
4. The terminal replies RRCConnectSetupCompute to the monitoring equipment to complete the access of the monitoring equipment side.
5. The detection and control equipment requires the terminal to report the IMSI through NAS information Ientity Request;
6. the terminal sends an Identity Response to report the IMSI to the detection device to complete the IMSI information acquisition.
Fig. 3 is a schematic flow chart of another method for ensuring continuous adsorption of terminals in a dense group according to an embodiment of the present invention, as shown in fig. 3, including:
301. receiving an NAS message which is sent by the monitoring equipment and carries a rejection reason value # 10;
302. and measuring the same-frequency cells of the monitoring equipment based on the rejection reason value #10, and determining the target cells meeting the access conditions so as to be adsorbed on the monitoring equipment corresponding to the target cells again.
It should be noted that, the main execution body in the embodiment of the present invention is the terminal, and it is understood that, when the terminal cannot satisfy the core network attach condition, the terminal attach request fails, and the NAS message sent by the snooping device is received when the terminal fails, specifically in step 301, the reject cause value included in the NAS message received by the terminal in the embodiment of the present invention is # 10. The specific snooping device issues the reject cause value through the Tracking area update reject.
Further, in step 302, after the terminal receives the rejection cause value #10, due to the terminal behavior specified by the rejection cause value #10, the terminal may re-measure the public network cell after being released from the monitoring device, determine a next target cell meeting the access condition, and then re-initiate an access request to the target cell to complete access.
It can be understood that if the same-frequency reselection is not adopted, for example, the frequency points are established as the frequency point and the second-frequency point of the strongest cell in the public network, the terminal will be continuously adsorbed by the monitoring and controlling device, resulting in a poor network of the terminal, or even no service. The situation can not occur by adopting the same-frequency reselection mode, and the problem of larger interference on a target terminal network in the existing adsorption rate improving scheme can be solved by combining the rejection reason value # 10.
The method for ensuring the continuous adsorption of the terminal in the dense group provided by the embodiment of the invention can ensure the continuous adsorption of the terminal and has less influence on the quality of a terminal communication network by adopting the rejection cause value #10 and a same-frequency reselection mode.
On the basis of the foregoing embodiment, after measuring the intra-frequency cell of the sensing device based on the reject cause value #10, and determining a target cell that meets an access condition to be re-attached to the sensing device corresponding to the target cell, the method further includes:
and sending the IMSI information to the monitoring equipment corresponding to the target cell through a reselection process.
As can be seen from the content of the foregoing embodiment, after receiving the NAS message carrying the reject cause value #10, the terminal provided in the embodiment of the present invention may re-determine the target cell for access, and then, in essence, for the re-determined target cell, the embodiment of the present invention may initiate a reselection procedure again to obtain the IMSI information again, thereby improving the acquisition rate.
On the basis of the embodiment, in the same networking, the frequency points of all the detecting and controlling equipment cells are the same, and the frequency point of the detecting and controlling equipment cell is the frequency point of the cell with the strongest signal in the public network.
It can be understood that the frequency points of all the cells of the monitoring equipment provided by the embodiment of the present invention are the same, so that when the same-frequency reselection is performed, the frequency point of the cell of the monitoring equipment is consistent with the resident frequency point before the target is adsorbed, and then the cell meeting the access condition is determined, so that the terminal is continuously adsorbed. Generally, in the embodiment of the present invention, the frequency point of the cell of the monitoring and controlling device is set as the frequency point of the cell with the strongest signal in the public network.
Fig. 4 is an interaction schematic diagram of a method for ensuring continuous terminal adsorption in a dense group according to an embodiment of the present invention, and as shown in fig. 4, an interaction flow of the method for ensuring continuous terminal adsorption in a dense group according to an embodiment of the present invention mainly includes steps (i) - (c), where:
the method comprises the following steps: when the terminal resides in the public network, the frequency point measurement of the monitoring equipment with higher priority than the serving cell is kept all the time;
step two: and when the signal strength (RSRP) of the monitoring equipment measured by the position of the terminal meets the reselection condition, the cell of the monitoring equipment is reselected. Initiating a connection establishment request (RRCConnectRequest);
step three: the monitoring device sends an RRCConnectSetup message to indicate that the access is available. The terminal replies RRCConnectSetupCompute to the monitoring equipment to complete the access of the monitoring equipment side.
Step IV: the detection and control equipment requests the terminal to report the IMSI information through the NAS message Ientity Request.
Step five: the terminal sends an Identity Response to report the IMSI information to the equipment.
Step (c): the terminal fails to complete the core network attach request, and receives the NAS message, which carries the reject cause value # 10. The snooping device issues the reject cause value by Tracking area update reject.
After the step (c), the terminal releases from the monitoring equipment according to the rejection reason value #10 and initiates a re-access request to the frequency point cell in the public network. And the signal of the detection and control equipment is stronger, and the terminal can initiate access to the detection and control equipment of the target cell again after being released. And the terminal moves to the control range of the detection and control equipment of the target cell, the process repeats the steps from the first step to the sixth step, the target IMSI is obtained again, and the capture rate is improved.

the reselection acquisition module 501 is configured to acquire target international mobile subscriber identity IMSI information of the adsorption terminal through a reselection process;
