Problems solved by technology

[0011] The existing ANR function is found in actual network applications. After the function is turned on, the system will automatically add some unnecessary super-distant neighbors (over-area coverage cells) or other types of redundant neighbors, and the addition of redundant neighbors It may cause a decrease in the success rate of UE handover in this area or increase unnecessary handovers, and occupy neighbor list resources and other negative effects

Embodiment 1

[0058] see figure 2 , the figure shows a method for optimizing the relationship between neighboring cells, the specific steps are as follows:

[0059] Step 201, obtaining the current neighboring cell relationship table of the serving cell;

[0060] In this embodiment, the current neighbor relationship table of the serving cell may be acquired in an existing acquisition manner, which will not be described here.

[0061] Step 202, obtaining the number of handover times and handover success rate of each pair of neighboring cell relationships, and / or obtaining the number of neighbor cell discovery times of each pair of neighboring cell relationships;

[0062] For example, take the first predetermined time interval as the handover KPI statistical period, and count the number of handovers and the handover success rate of each pair of adjacent cell relationships. Optionally, the first predetermined time interval can be in units of hours, such as 1 hour, of course It is not limited...

Embodiment 2

[0081] see image 3 , the figure shows the processing flow of the method for automatically optimizing the neighbor relationship attributes, and the specific steps are as follows:

[0082] Step 301, obtaining the current neighboring cell relationship table of the serving cell serving cell;

[0083] Step 302, taking Th as the handover KPI statistical period to count the number of handovers HoNum(i) and handover success rate HoSuccRate(i) of each pair of neighboring cell relations SC-Nc(i);

[0084] Step 303, judging whether the number of handovers HoNum(i) is greater than the set handover number of times threshold HoNumThresh and whether the handover success rate HoSuccRate(i) is less than the set handover success rate threshold HoSuccRateThresh, if the number of handovers HoNum(i) is greater than the set handover The number of times threshold HoNumThresh and the handover success rate HoSuccRate(i) is less than the set handover success rate threshold HoSuccRateThresh, enter ste...

Embodiment 3

[0100] see Figure 5 , the figure shows the structure of a device for optimizing the relationship between neighboring cells, and the device 500 includes:

[0101] The first obtaining module 501 is used to obtain the current neighboring cell relationship table of the serving cell;

[0102] The second acquiring module 502 is configured to acquire the number of handovers and handover success rate of each pair of neighboring cell relationships, and / or acquire the number of neighboring cell discovery times of each pair of neighboring cell relationships;

[0103] An optimization module 503, configured to perform an operation on the current neighbor relationship table of the serving cell according to the number of handovers and the success rate of handovers for each pair of neighbor relationships, and / or the number of neighbor discovery times for each pair of neighbor relationships Optimized handling.

[0104] In this embodiment, optionally, the second obtaining module includes:

Abstract

An embodiment of the invention provides a method and device for optimizing relations between adjacent cells. The method comprises the following steps: a current table for relations between the adjacent cells is obtained, switching frequency and switching success rates of a relation between each pair of adjacent cells are obtained, and / or adjacent cell discovering frequency of the relation betweeneach pair of neighboring cells is obtained; the current table for relations between the adjacent cells is optimized according to the switching frequency and switching success rates of the relation between each pair of adjacent cells and / or adjacent cell discovering frequency of the relation between each pair of neighboring cells; switch between unreasonable adjacent cells that are automatically added in actual network application of an existing ANR function can be reduced, and redundant adjacent cells can be reduced.

Description

technical field [0001] The present invention relates to the field of wireless technology, in particular to a method and device for optimizing neighbor cell relations. Background technique [0002] ANR (Automatic Neighbor Relation), that is, "automatic neighbor relationship", means that the network side can automatically complete the neighbor relationship by using the UE's measurement and reporting function of the surrounding neighbor PCI (Physical Layer Cell Identity) and CGI (Cell Unique Identity) Table configuration and optimization. [0003] see figure 1 , the figure shows a complete ANR neighbor cell automatic addition process, which is applicable to the addition of intra-frequency neighbor cells and inter-frequency neighbor cells at the same time. [0004] After the UE accesses the network, the base station will deliver the measurement configuration (generally A3 measurement event parameters) to the UE as the threshold and basis for neighbor cell measurement and repor...
