Embodiment 1

[0030] refer to image 3 , shows a flow chart of steps of a method for exchanging load information of base stations according to Embodiment 1 of the present invention.

[0031] The base station load information interaction method in this embodiment includes the following steps:

[0032] Step S202: the first base station receives the resource status update message reported by the second base station according to the first time period.

[0033] When the base station needs to implement load balancing due to the lack of its own resources, the load information of the base station can be transmitted between the base stations through the X2 interface. For example, the first base station sends a Resource Status Request message to the second base station, requesting the second base station to report Resource status information, which includes the resource content that the second base station needs to report, such as radio resource status (Radio Resource Status), S1 interface transmiss...

Embodiment 2

[0044] refer to Figure 4 , shows a signaling interaction diagram of base station load information interaction according to Embodiment 2 of the present invention.

[0045] In this embodiment, the first base station is represented by eNB1, and the second base station is represented by eNB2. A timer t3 is added to eNB1, and the information carried in the RESOURCE STATUS UPDATE (resource status update) message reported by eNB2 by t3 satisfies one of the following conditions One, then eNB1 starts timer t3:

[0046] (1) radio resource usage (wireless resource usage) (can be UL / DL GBR PRB usage (uplink / downlink guaranteed bit rate physical resource block usage), or UL / DL non-GBR PRB usage (uplink / downlink non-guaranteed Bit rate physical resource block usage), or UL / DL total PRB usage (uplink / downlink total physical resource block usage)), that is, UL / DL PRB usage (uplink / downlink physical resource block usage) exceeds this area (ie eNB1) The preset threshold for judging the overl...

Embodiment 3

[0095] refer to Figure 5 , shows a flow chart of steps of a method for exchanging load information of base stations according to Embodiment 3 of the present invention.

[0096] In this embodiment, the first base station is still denoted by eNB1, the second base station is still denoted by eNB2, and the start condition of the timer t3 in eNB1 is still as described in the second embodiment.

[0097] The base station load information interaction method in this embodiment includes the following steps:

[0098] Step S402: eNB1 determines that load balancing needs to be implemented according to its own load status, and sends a Resource Status Request message to eNB2.

[0099] For example, eNB1 detects that the load of the cell reaches or exceeds the set threshold, where the load of the cell can be one or more of radio resources, transport network layer load, hardware load, or comprehensive available capacity group, or it can be a A parameter that generally characterizes the cell ...

Abstract

The invention provides a base station load information interaction method and a base station. The base station load information interaction method includes the steps that a first base station receives resource state update information reported by a second base station according to a first time period; when the second base station is determined to be in a load prewarning state or a high-load state according to the resource state update information, a preset timer is started; whether all the received resource state update information, reported according to the first time period, of the second base station indicate that the second base station is in the load prewarning state or the high-load state in a second time period set by the timer is judged; if the answer is yes, when the second time period set by the timer is overtime, information used for indicating that reporting of the resource state update information is stopped is sent to the second base station, so that the second base station stops reporting the resource state update information to the first base station. By means of the method, X2 link resource waste caused by continuous interaction and influences on normal switching on an X2 link are reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a load information interaction method between base stations and a base station. Background technique [0002] In the field of communication, due to the difference in propagation characteristics, the F frequency band (1880-1920MHZ) has the advantage of larger coverage than the D frequency band (2575-2615MHZ), but the F frequency band has fewer frequency resources than the D frequency band. If only the F-band is deployed in the TD-LTE (Time Division-Long Term Evolution) network, the system capacity will be insufficient in hotspot areas with relatively large data flow requirements. When using the double-layer networking method with the same coverage of D-band and F-band, the coverage advantages of F-band and the frequency resource advantages of D-band can be used at the same time to achieve coverage through F-band in the edge area and load sharing through D-band in the centra...
