Problems solved by technology

[0006] In the process of adjusting the frequency point above, if the frequency point of the macro cell changes frequently, manual configuration cannot adjust the frequency point of the micro cell in real time, which will increase the co-channel interference between the macro cell and the micro cell and affect the frequency point of the micro cell. The maintenance and configuration workload of

Embodiment 1

[0029] Embodiment 1 of the present invention provides a frequency point adjustment method, such as figure 1 As shown, the method may include:

[0030] S101. Determine that the frequency point of the served macro cell group changes;

[0031] Wherein, the macro cell group includes at least one macro cell.

[0032] The serving macro cell group refers to a collection of all macro cells served by a micro cell; a micro cell may serve one or more macro cells.

[0033] Specifically, the change of the frequency point of the serving macro cell group means that the frequency points of one or more macro cells in the macro cell group served by the micro cell change.

[0034] Optionally, if the frequency of the serving macro cell group changes, the frequency of macro cells in the macro cell group serving the micro cell is changed; where the preset threshold can be determined according to actual needs , the present invention does not specifically limit it.

[0035] Preferably, the preset...

Embodiment 2

[0082] Embodiment 2 of the present invention provides another frequency point adjustment method, such as figure 2 As shown, the method may include:

[0083] S201. The frequency point of the macro cell group that the micro cell determines to serve changes;

[0084] It should be noted that the change of the frequency point of the macro cell group that is determined to be served has been described in detail in S101 and will not be repeated here.

[0085] S202. The micro cell obtains the current frequency point set of the macro cell group serving;

[0086] It should be noted that the current frequency point set of the macro cell group that obtains the service has been described in detail in S102, and will not be repeated here.

[0087] S203. The micro cell sorts each of the available frequency points of the micro cell according to the number of times the frequency points are included in the current frequency point set of the serving macro cell group;

[0088] Am...

example 1

[0093] Example 1. Suppose the available frequency points of the micro cell are f1, f2, f3, f4, f5, f6, f7, f8, f9, f10, f11;

[0094] Assume that the current frequency occupancy of the macro cell group served by the micro cell is as shown in Table 1:

[0095] Table 1

[0096] Macro cell ID

Identification of occupied frequency point information

macro cell 1

Abstract

The invention discloses a frequency point regulating method and device and relates to the technical field of communication. The frequency point regulating method and device realize to duly regulate frequency points of a micro cell so as to lower the same frequency interference between a macro cell and the micro cell and reduce the workload for maintaining and configuring the frequency points of the micro cell. According to the technical scheme, the frequency point regulating method includes that confirming that frequency points of a served macro cell group are changed, wherein the macro cell group comprises at least one macro cell; acquiring the current frequency point set of the served macro cell group; selecting N frequency points from available frequency points of the micro cell according to the carrier number N of the micro cell, wherein the included times of the N frequency points in the current frequency point set of the macro cell group are increased in sequence in the available frequency points, and N is larger than or equal to 1; regulating the frequency points of the micro cell according to the selected N frequency points. The frequency point regulating method and device are used for regulating the frequency points of the micro cell.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for adjusting a frequency point. Background technique [0002] With the rapid development of smart terminals and mobile Internet technologies, users have higher and higher requirements for wireless data traffic. The existing spectrum and sites can no longer meet the needs of users. Therefore, operators deploy a large number of low-power The edge-shaped cellular access point (micro cell) forms a low-power node layer and reuses the existing spectrum resources of the system in large quantities. [0003] Due to the large reuse of existing spectrum resources in the system between macro cells and micro cells, micro cells and micro cells, co-frequency interference will occur between macro cells and micro cells, and between micro cells and micro cells; in order to minimize For co-channel interference, when configuring frequency points, the frequency po...
