Problems solved by technology

[0009] The process of load information exchange is only used for the base station where the adjacent cell is located. In this way, the corresponding figure 1 , the heavy-loaded cells A and C only know the load information of the adjacent light-loaded cell B; and, the available load capacity in the load information (RESOURCE STATUS Update message) provided by the light-loaded cell B is used to indicate that the cell B can The resources used; therefore, as neighbors of B, A and C will transfer loads to B at the same time at a certain moment, which may cause B to be heavily loaded or even congested
And once B reaches the heavy load state, it will also trigger the adjustment of load balance, so that the load will be transferred back and forth between A, B, and C, that is, the load balance will be oscillated and adjusted.
[0010] An existing solution to load balance oscillation adjustment is to let A and C exchange load information, so as to know that B has a heavy load neighbor cell; however, whether there is an X2 interface between the base station and its own second circle base station is a problem , that is, the base stations where A and C are located cannot apply figure 2 Directly exchanging load information, and forwarding messages through cells will cause delay problems; in addition, exchanging load information with neighboring cells (A and C) in adjacent cells will lead to too many interacting nodes, which will increase the load on the network

Embodiment 3

[0122] This embodiment relates to the load balancing process in the LTE system, refer to Figure 5 Shows the topological structure of the cell, where the cell in dark color represents the cell with heavy load, the cell in light color represents the cell with light load, and the numerical value in the cell with light load represents the downlink available capacity value;

[0123] This embodiment takes the load balancing process of cell 1 as an example to introduce; for simplicity, each base station is an omni-directional base station, so each base station has only one cell, and the number of the cell is the same as the number of the base station.

[0124] Step D1, the base station 1 performs periodic load information statistics on the cell 1;

[0125] Step D2, judging whether cell 1 triggers the load balancing process;

[0126] For example, if the available uplink capacity value obtained through statistics is 15 and the available downlink capacity value is 20, which are respec...

Embodiment 4

[0137] This embodiment relates to the load balancing process in LTE and UMTS systems, refer to Figure 6 , the macro base station is TD-SCDMA, and there are multiple LTE home base stations within its coverage area for hotspot coverage. At a certain moment, HeNB2 and HeNB3 are in a heavy load state, and need to perform a balanced process, and the two home base stations are respectively in hybrid mode;

[0138] This embodiment takes the load balancing process of the home base station HeNB2 as an example to introduce; assuming that each base station is an omni-directional base station, the home base station HeNB2 has a cell 2, the home base station HeNB3 has a cell 3, and the base station NodeB1 has a cell 1

[0139] Step E1, the home base station HeNB2 periodically collects the load information of the cell 2;

[0140] Step E2, judging whether cell 2 triggers the load balancing process;

[0141] For example, if the uplink available capacity value in the statistical information ...

Embodiment 5

[0155] This embodiment mainly describes the application scenario on the expressway, refer to Figure 7 , there are 9 base stations in the map, and their numbers are 2-10. Due to the high traffic flow on the Fourth Ring Road, the load in the coverage area of ​​the cell increases;

[0156] In this embodiment, the load balancing process of the base station 4 is taken as an example for introduction, and it is assumed that each base station is an omni-directional base station.

[0157] Step F1, the base station 4 performs periodic load information statistics;

[0158] Step F2, judging whether the base station 4 triggers the load balancing process;

[0159] For example, in the load information collected by the base station 4, the uplink available capacity value is 15, and the downlink available capacity value is 20, which are respectively lower than the respective thresholds of 30, and the base station 4 triggers the load balancing process.

[0160] Step F3, for the base station 4...

Abstract

The invention provides a base station communication method and a base station, wherein the communication method of a source base station used for interaction of load information specifically comprises the following steps that: the source base station periodically counts the load information of each subordinate cell belonging to the source base station; and the source base station judges whether a cell triggers a load balancing process, if so, the source base station transmits the load information of the cell to a target base station. The method and the base station are used for reducing shock adjustment of load balancing better.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a base station communication method and a base station. Background technique [0002] In the future mobile communication system, it is hoped that by introducing a network self-optimization mechanism, the manual participation in network planning and operation and maintenance will be reduced, and the cost of network construction and operation will be reduced, that is, the network will automatically optimize parameters according to statistics. In this context, the SON (Self Organizing Networks) technology of the LTE (Long Term Evolution) system is being studied as a working topic of the 3GPP (3rd Generation Partnership Project); The SON technology may include self-configuring, self-optimizing and self-healing functions. [0003] Mobility Load Balancing (MLB, Mobility Load Balancing) is an important research in the self-optimization function of SON. Its basic goal is t...
