[0097] see figure 1 As shown, the first embodiment of the present invention provides a communication cooperation method for a cooperation source base station, including the following steps 101 to 103, which are described in detail below.

[0098] Step 101: Determine a cooperation target base station.

[0099] In the embodiment of the present invention, when the cooperation source base station determines the cooperation target base station, the following methods can be adopted:

[0100] First, the cooperation source base station interacts with the initial target base station to obtain the cooperation parameters of the initial target base station. The initial target base station is a base station covering mobile communication terminals in the service area; then, the cooperation source base station uses the obtained cooperation parameters from all A base station that satisfies the cooperation screening condition is selected from the initial target base stations as the cooperatio...

[0162] see Figure 8 As shown, the second embodiment of the present invention provides a communication cooperation method for the cooperation target base station, including the following steps 801 to 802, which are described in detail below.

[0163] Step 801: Receive a multi-connection request message sent by a cooperation source base station.

[0164] In the embodiment of the present invention, the multi-connection request message is used to request the cooperation target base station to allow mobile communication terminals that have accessed the cooperation source base station to simultaneously access the cooperation target base station.

[0165] Specifically, before the step 801, the communication cooperation method further includes:

[0166] Sending cooperation parameters to the cooperation source base station, so that the cooperation source base station can select the cooperation target base station from all initial target base stations according to the cooperation para...

Abstract

The invention provides a communication cooperation method and device. The communication cooperation method comprises the steps of determining a cooperative target base station, and sending a multi-connection request message to the cooperative target base station, sending a multi-connection command to a mobile communication terminal, when a multi-connection request response message which is returned by the cooperative target base station and allows access of the mobile communication terminal is received, so that the mobile communication terminal can be connected to the cooperative target base station according to the multi-connection command, and cooperative transmission of the data service is realized through a cooperation source base station and the cooperative target base station. Compared with a multi-connection base station method of a mobile communication terminal in the prior art, the scheme provided by the invention has the advantages that the signaling overhead can be reduced,the processing burden of the base station can be relieved, and the switching time delay can be avoided.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a communication cooperation method and device. Background technique [0002] In order to ensure the continuity of network coverage, 3GPP standardization proposes a method of adding micro base stations within the coverage area of ​​macro base stations. In hotspot areas with high density of mobile communication terminals, with the assistance of micro base stations, mobile communication terminals can be dual-connected to macro base stations and micro base stations. Through the mobility management of macro base stations, they can obtain better network services, thereby improving the network Coverage quality, improve load balancing between base stations, and increase system throughput to a certain extent. [0003] However, this dual-connection base station method is limited by the network capacity between the macro base station and the micro base station. It is...
