Detailed Description
the following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
fig. 2 is a flowchart of a terminal access tracking method according to an embodiment of the present invention; referring to fig. 2, the method includes:
S201: acquiring cell information of a current cell accessed to a terminal to be tracked;
the method of the present embodiment is executed mainly by the RNC device.
It is understood that the cell information is information for distinguishing different cells, that is, a corresponding cell may be determined according to the cell information.
s202: determining a current core network by searching a corresponding relation according to the cell information of the current cell, wherein the corresponding relation is a corresponding relation between cell information and the core network which is established in advance;
in a specific implementation, the correspondence may be implemented by a correspondence table, that is, the correspondence is stored in a table form.
It should be noted that a core network includes a set of MSCs and a set of SGSNs, and refer to fig. 3.
s203: and accessing the terminal to be tracked to the current core network, and using the current core network as the access position of the terminal to be tracked so as to realize the tracking of the terminal to be tracked.
In this embodiment, a corresponding relationship between cell information and a core network is pre-established, a current core network is determined by searching the corresponding relationship according to cell information of a current cell accessed to a terminal to be tracked, the terminal to be tracked is accessed to the current core network, and the current core network is used as an access position of the terminal to be tracked, so that the terminal to be tracked can be accessed to a fixed core network, and network maintenance, abnormal positioning discovery and abnormal troubleshooting are facilitated.
Fig. 4 is a flowchart of a terminal access tracking method according to an embodiment of the present invention; referring to fig. 4, the method includes:
S401: judging whether the Iu-flex function is started, if so, executing step S201;
in a specific implementation, if the Iu-flex function is not turned on, a default core network is selected for access according to the prior art, and certainly, the problem that which core network the terminal accesses cannot be determined does not occur.
it is understood that the Iu-Flex function is that the RNC device is connected to multiple core network nodes (MSC/SGSN), and the terminals are distributed to different core network nodes according to the principle of load balancing.
it should be noted that the core network node is identified by an NRI (network resource identifier) which is generated by the TMSI/P-TMSI information of the terminal itself.
when the terminal accesses the core network according to the Iu-Flex function, the access network equipment (namely, the RNC) routes the uplink message of the terminal to different core network nodes according to the NRI value.
s402: acquiring cell information of a current cell accessed to a terminal to be tracked;
Step S402 is the same as step S201 of the embodiment shown in fig. 2, and is not described again here.
S403: judging whether the cell information of the current cell is in the corresponding relation, if so, executing a step S404;
it can be understood that, if the cell information of all the cells is set in the corresponding relationship, in this case, the cell information of the current cell is necessarily in the corresponding relationship, but since in some cases, for example, during the process of testing the cell and the core network, or during the process of normal operation of the cell and the core network, only a part of the cell information of the cell may be set in the corresponding relationship, in this case, the cell information of the current cell is not necessarily in the corresponding relationship, if not in the corresponding relationship, the current core network cannot be determined by searching the corresponding relationship, so before searching the corresponding relationship, it may be determined whether the cell information of the current cell is in the corresponding relationship, if the cell information of the current cell is in the corresponding relationship, then step S404 is executed to search the corresponding relationship, if the cell information of the current cell is not in the corresponding relation, the core network is directly selected to be accessed according to the Iu-flex function without executing subsequent steps.
It should be noted that, in order to prevent other terminals from accessing the core network in the correspondence, the access range of the core network in the correspondence may be set to be 0, that is, only the terminal of the cell corresponding to the core network is allowed to access, and other terminals are not allowed to access.
S404: determining a current core network by searching a corresponding relation according to the cell information of the current cell, wherein the corresponding relation is a corresponding relation between cell information and the core network which is established in advance;
step S404 is the same as step S202 in the embodiment shown in fig. 2, and is not described again here.
s405: acquiring the cell information of the terminal to be tracked, matching the cell information of the terminal to be tracked with the cell information of the current cell, and executing the step S406 if the matching is successful;
it should be noted that, since the terminal to be tracked can be accessed through the current cell, the current cell is in an operating state, but in order to prevent the current cell from having an abnormal operation, in this embodiment, whether the current cell has an abnormal operation is determined by matching the cell information of the terminal to be tracked with the cell information of the current cell, and when the matching is successful, it may be understood that the current cell has no abnormal operation, and step S406 is continuously executed.
when the matching is unsuccessful, the current cell can be understood to have abnormal operation, the current core network does not exist, the current core network cannot be accessed, and the core network is directly selected to be accessed according to the Iu-flex function.
S406: judging whether the current core network is abnormal or not, if not, executing a step S407;
It can be understood that, before accessing the current core network, it is necessary to determine whether the current core network is abnormal, for example, the current core network cannot be searched, and when the current core network is not abnormal, the current core network may be accessed, and the step S407 is continuously executed;
When the current core network is abnormal, the current core network cannot be accessed at the moment, the current core network is considered to be not existed, and the core network is required to be selected to be accessed according to the Iu-flex function.
s407: and accessing the terminal to be tracked to the current core network, and using the current core network as the access position of the terminal to be tracked so as to realize the tracking of the terminal to be tracked.
Step S407 is the same as step S203 of the embodiment shown in fig. 2, and is not described again here.
Compared with the prior art, the method of the embodiment has the main advantages that:
1. Compared with the Iu-flex function, the corresponding relation between the cell and the core network is realized more flexibly, the terminal access mode is more flexible and controllable, and the network maintenance is facilitated;
2. The problem positioning of maintenance personnel when the network is abnormal is facilitated, and the cells and the core network can be isolated independently to remove obstacles;
3. The test means is richer, and the test tools of different manufacturers can be loaded to simultaneously test the RNC equipment.
