Description
The application is a divisional application with the application number of 201710195422.2, the application date of 2017, 3 and 29, and the name of 'a method and a system for configuring adjacent cells'.
Technical Field
The present invention relates to the field of mobile communications, and in particular, to a method and a system for configuring a neighboring cell, which improve cell switching efficiency.
Background
Through the development of several generations, the mobile communication technology becomes the communication mode which is the most widely used in daily life. Global 4G networks, represented by LTE networks, continue to increase, users are steadily growing, and the global 4G market has entered a rapid growth from the inception stage. With the development of LTE, base stations are increasing, and complex neighboring cell relations will result in missed cells and wrong cells, which in turn will result in failure and call drop when cells are switched, so accurate neighboring cell relation configuration is a basic requirement for ensuring mobile network performance.
The existing method for configuring the neighboring cell relationship mainly includes the following two methods:
the first is manual maintenance, that is, a neighboring cell around the source cell is manually added by a human. With the development of wireless networks, especially the deployment of small base stations, the method is more difficult and more costly.
The second method is to automatically configure the neighbor cell in an ANR manner, that is, the terminal switches and measures the missed neighbor cell, and obtains the missed neighbor cell information in a manner reported by the terminal, and adds the missed neighbor cell information to the neighbor cell list. However, the ANR method has many limitations, for example, if a terminal that supports CGI reporting needs to detect the missing neighbor cell information, the measurement is based on a frequency point instead of a neighbor cell list, and only the neighbor cell of a preconfigured frequency point can be measured, and the collection of the neighbor cell information is incomplete due to these limitations; more importantly, the measurement information reported by the terminal does not include the type of the base station and the type of the link included between the base station corresponding to the source cell and the base station corresponding to the neighboring cell; when cell switching is carried out, the type of a base station corresponding to a target cell needs to be configured, if the type of the base station is configured wrongly, the cell switching fails, the phenomenon of call drop is caused, and the user experience is influenced; in addition, the X2 link can enable adjacent base stations to communicate directly, so that seamless switching of users in the whole network is guaranteed, the S1 link can enable the base stations to communicate with the core network, and the core network forwards data to other base stations, so that the communication efficiency of the S1 link is lower than that of the X2 link; since each LTE base station includes an S1 link but does not necessarily include an X2 link, when performing cell handover, the source base station generally tries to establish an X2 connection with the target base station, and sends data of the mobile terminal to the target base station through the X2 link, and if the X2 connection fails to be established, then communicates with the target base station through the S1 link. Therefore, if it is not known whether the X2 link is included between the base station corresponding to the source cell and the base station corresponding to the target cell before the cell handover is performed, the efficiency of the cell handover may be reduced.

s1, detecting a neighbor cell of a source cell by using more than two modes;
s11, when a second base station corresponding to a source cell is started, detecting a neighboring cell according to a preset frequency sweeping point; the method comprises the following specific steps:
obtaining a corresponding physical cell identification code according to the preset frequency sweeping point; the preset frequency points of the sweep frequency comprise frequency points automatically collected by a base station in the operation process and frequency points configured according to frequency point information commonly used by communication operators, for example, 379000, 38098, 38400 and 38950 are frequency points commonly used by communication operators; acquiring LTE cell system information corresponding to the physical cell identification code; analyzing the LTE cell system information to obtain the neighbor cell information;

For example, as shown in fig. 3, when the second base station (base station a) is started, the second base station starts a network probing function, traverses a preset frequency sweeping frequency point, and searches for a physical cell identifier (including physical cell identifiers of base stations B, C, and G) corresponding to the frequency sweeping frequency point within the coverage area of the second base station (base station a) to form a physical cell identifier list; and traversing the searched physical cell identification code list, acquiring corresponding information such as MIB and SIB, and analyzing the MIB and SIB information to obtain neighboring cell information. The method utilizes the network detection function of the base station, so that the base station can actively monitor the cell signals of the adjacent base stations in the coverage area of the base station, obtain corresponding frequency points, physical cell identification codes and the like, has high accuracy and has great auxiliary effects on the aspects of base station switching, PCI optimization and the like. Therefore, when the second base station is started, namely when the second base station is initialized, the method is firstly used for scanning the cell information of the adjacent base stations in batch;
s12, in the running process of the second base station, adopting a method for acquiring adjacent cell information according to the preset frequency sweeping frequency point at a preset time interval, and analyzing one or more than two combinations in an X2 interface signaling method by a terminal reporting measurement information method, an S1 switching signaling method and an X2 interface signaling method;
the method for acquiring the neighbor cell information according to the preset frequency sweeping frequency point by adopting the preset time interval specifically comprises the following steps: monitoring frequency point information in the coverage range of a second base station (base station A) according to a preset sweep frequency point at regular time according to a set scanning period; for example: the source cell base station collects the frequency point information in SIB5 (LTE adjacent cell information) and SIB7 (GERAN adjacent cell information) of adjacent cells, collects the frequency point information in the information reported by the terminal, collects the frequency point information in S1/X2 interface signaling, and starts the network detection function of the base station to detect the adjacent cell information under the corresponding frequency point by taking the automatically collected frequency points as frequency sweeping frequency points;

in the operation process of the second base station, the method for acquiring the neighbor cell information by analyzing the X2 interface signaling specifically comprises the following steps: the method comprises the steps that a missing neighbor cell initiates an X2 connection establishment request to a base station corresponding to a source cell, and the base station corresponding to the source cell analyzes an establishment request signaling to obtain the information of the missing neighbor cell; for example, as shown in fig. 3, a base station G initiates an X2 establishment request to a second base station (base station a), and if X2 is successfully established, the second base station (base station a) adds the base station G to a neighbor cell list and identifies an X2 interface switching; otherwise, identifying the switching of the S1 interface; if the X2 is successfully established, the base station G informs the neighbor cell information (base station E) of the second base station (base station A) through the X2 configuration updating command, and the second base station (base station A) adds the base station E into a neighbor cell list to identify a second-order neighbor cell;
after the second base station is installed in a new environment for a period of time, a method for acquiring neighbor cell information according to preset sweep frequency points at preset time intervals is adopted, a method for reporting measurement information by a terminal, a method for analyzing S1 switching signaling and a method for analyzing X2 interface signaling are adopted, and one or more than two combinations of the methods are used for detecting the information of peripheral cells in real time, so that the integrity of collecting neighbor cell information is improved, and the success rate of switching the mobile terminal in a neighbor interval is improved.

And S4, setting the level of the adjacent region.
The adjacent cell directly adjacent to the base station corresponding to the source cell is a first-order adjacent cell, and the adjacent cell which is two hops away from the base station corresponding to the source cell is a second-order adjacent cell; for example, the neighbor cell detected by the method for analyzing the X2 interface signaling is marked as a second-order neighbor cell.
S5, updating the neighbor cell to neighbor cell list; and sending the neighbor cell list to a base station corresponding to the neighbor cell.
For example, as shown in fig. 4, the base stations X, Y, Z establish an X2 relationship with each other, at this time, a new base station W is added, the base station W establishes an X2 connection with the base station Z, the base station Z informs the base station X and the base station Y through a configuration update signaling after collecting cell information of the base station W, and similarly, the base station Z also sends its own neighbor list to the base station W, so that efficiency and integrity of obtaining neighbor information can be improved.
S6, maintaining the base station types of the adjacent cells in the adjacent cell list; and switching the S1 interface between the base station corresponding to the source cell and the adjacent cell with the base station type attribute of failure in the adjacent cell list, if the switching is successful, the base station type attribute of the adjacent cell is converted into success if the set base station type of the adjacent cell is correct, if the switching is failed, comparing the switching failure frequency with a preset switching threshold value, and if the switching failure frequency exceeds the preset switching threshold value, modifying the base station type of the adjacent cell.
