Under the condition that the current 5G core network NGC (Next Generation CORENGC, the next generation core network) is not ready, in order to rapidly deploy 5G services, operators preferably adopt NSA (non-independent networking) architecture networking, an option3x is used as a main stream networking scheme, the scheme is upgraded through an LTE station to support a signaling anchor point serving as NSA, a mobile terminal needs to be firstly accessed into an anchor point LTE base station, the anchor point LTE base station sends 5G base station cell configuration information to the terminal, namely after SCG (Secondary Cell Group, auxiliary cell group) cells are added, the terminal can normally acquire the 5G services.
Because of the imperfect deployment and planning of the current network, not all LTE sites are upgraded to signaling anchor points of NSA, many LTE base stations do not support providing 5G services, but only 4G services. From the current network test situation, a plurality of LTE cells are often covered at the same position, but the signaling anchor point updated to NSA is few, so that the existing mobile terminal can only be resident in a non-anchor cell.
In the prior art, the mobile terminal needs to decode the system message of the cell to determine whether the cell is an NSA anchor cell, and according to the current standardized searching scheme, the 5G mobile terminal can often only stay in a non-anchor cell after the actions such as starting up, cell reselection, cell switching and the like occur, so that the user can not acquire 5G network service easily. How to make a 5G mobile terminal stay in an NSA anchor cell as much as possible and use a 5G network service, so as to ensure that a 5G user obtains a network service with good perception and experience is a current urgent problem to be solved.

step S202, the mobile terminal compares the current position information with position information corresponding to each anchor point cell in a history stored anchor point cell list to judge whether the distance difference value is smaller than a preset threshold value;
specifically, the distance difference value is obtained by calculating the difference value between the longitude value and the latitude value of the current position and the longitude value and the latitude value in the history anchor point cell list;
the size of the preset threshold is related to the coverage radius of the LTE cell, and the comparison with the preset threshold is used for judging whether the current position is in the coverage of the LTE cell in the history anchor point cell list.
Step S2021, when the distance difference is smaller than the predetermined threshold, indicating that there may be an NSA anchor cell in the environment where the mobile terminal is located;
step S2022, when the difference in distance is greater than the predetermined threshold, indicates that there may be no anchor cell in the environment where the mobile terminal is located.

Referring to fig. 3, a flowchart of a method for adding NSA anchor cell information to a neighbor cell list for cell reselection based on a NSA anchor cell list stored in history after cell reselection occurs in a mobile terminal according to a third embodiment of the present invention is shown.
In the third embodiment, the mobile terminal has a GPS (global positioning system) function. As shown in fig. 3, when the mobile terminal decodes the system message of the cell after cell reselection, if the cell is confirmed to be a non-NSA anchor cell, current position information is obtained, and whether the distance difference value is smaller than a predetermined threshold value is judged by comparing the current position information with position information corresponding to each anchor cell in a history anchor cell list, so as to detect and judge whether available anchor cells possibly exist in the environment where the mobile terminal is located, and the NSA anchor cell is added to a neighbor cell list of cell reselection.
The processing of the third embodiment is specifically described below.

Here, the location information of the mobile terminal refers to a longitude value and a latitude value of the current location of the mobile terminal;
step S302, the mobile terminal compares the current position information with the position information corresponding to each anchor point cell in the history anchor point cell list one by one, and judges whether the distance difference value is smaller than a preset threshold value;
specifically, the distance difference value is obtained by calculating the difference value between the longitude value and the latitude value of the current position and the longitude value and the latitude value in the history anchor point cell list;
the size of the preset threshold is related to the coverage radius of the LTE cell, and the comparison with the preset threshold is used for judging whether the current position is in the coverage of the LTE cell in the history anchor point cell list.
Step S3021, when the distance difference is smaller than a predetermined threshold, indicating that an NSA anchor cell may exist in the environment where the mobile terminal is located;
step S3022, when the distance difference is greater than the predetermined threshold, it indicates that there may be no anchor cell in the environment where the mobile terminal is located.

when the distance difference value is smaller than a preset threshold value, indicating that NSA anchor point cells possibly exist in the environment where the mobile terminal is located; the mobile terminal adds the NSA anchor point cell to a neighbor cell list of cell reselection, sets the neighbor cell list as the highest priority, facilitates the mobile terminal to detect the signal strength of the neighbor cell, and updates the NSA anchor point cell after the signal strength reaches a preset threshold;
when the distance difference value is larger than a preset threshold value, indicating that an anchor point cell possibly does not exist in the environment where the mobile terminal is located; when the judging result shows that the mobile terminal is in the environment where the anchor point cell is probably not present, the IDLE state measurement is carried out by using the neighbor cell list of the cell reselection configured in the system message of the cell standard.
In the embodiment of the present application, when a mobile terminal decodes a system message of a cell after finding an LTE cell in an NSA network through the mobile terminal, the decoding judging unit 501 judges whether the current cell is an NSA anchor cell, if the current cell is confirmed to be an NSA anchor cell, the acquiring location unit 502 acquires location information of the current mobile terminal, the comparing and analyzing unit 503 compares the location information corresponding to each anchor cell in a NSA anchor cell list stored in history with the cell information, judges whether the cell exists in the NSA anchor cell list stored in history, if the anchor cell does not exist in the NSA anchor cell list stored in history, the storing unit 504 adds the anchor cell into the NSA anchor cell list stored in history, and stores the updated NSA anchor cell list in the mobile terminal, thereby ensuring that the mobile terminal satisfies the NSA anchor cell as much as possible and uses 5G network service, and ensuring that a 5G user obtains a perceived excellent and experienced network service.
