Embodiment 1

[0051] Embodiment 1 Handover process between base stations (inter eNB) in cooperative mode based on X2 interface

[0052] Such as figure 2 As shown, it is the handover process between base stations (inter eNB) in the joint processing (JP) cooperation mode in the cooperation mode based on the X2 interface. The steps and status of the whole process are described in detail below:

[0053] First, the data packet of the user service is transmitted from the SGW (Signaling GateWay, signaling gateway) to the source cell (ie, the serving base station, which includes the serving cell), and is sent to the user terminal (ie, UE) after being processed by the source cell;

[0054] 1. Measurement report: UE measures various channel information according to the measurement method configured by the base station, and reports the measurement results that meet the reporting requirements;

[0055] The measurement configuration and measurement result reporting criteria need to consider the requir...

Embodiment 2

[0076] Embodiment 2 Handover process in the base station (intra eNB) in the cooperative mode of joint processing (JP)

[0077] In the joint processing (JP) cooperation mode, the handover process information interaction in the base station (intra eNB) is basically the same as that in Embodiment 1, the only difference is that the source cell and the target cell belong to the same base station eNB, so the source cell and the target cell communicate It is not necessary to transmit information through the X2 interface, and it is directly completed through the communication mechanism inside the eNB. The way of sending information and the processing when receiving information are consistent with the first embodiment.

Embodiment 3

[0078] Embodiment 3 In the cooperation mode of joint processing (JP), the handover process between base stations (intereNB) based on the S1 interface.

[0079]In the joint processing (JP) cooperation mode, the handover process information interaction of the inter eNB through the S1 interface is basically the same as that in Embodiment 1. The only difference is that the source cell and the target cell cannot communicate directly, and the information needs to be forwarded through the S1 interface. The signaling form Follow the relevant standards of the S1 interface. Information and its processing between the source cell and the target cell and between the UE and the core network are consistent with those in Embodiment 1.

[0080] The resource allocation optimization method for CoMP JP cooperation technology switching in the present invention utilizes the characteristics of JP type cooperation, reduces unnecessary steps compared with the existing switching process, avoids repeate...

Abstract

The invention discloses a radio communication system and a method of resource configuration optimization during switching in a coordination set in the system, used for carrying out resource configuration optimization during switching in the coordination set. In the process of switching in a joint processing coordination set, when a target cell learns that a switched user is a coordinated user, the switched user is directly judged to be accessed and only a signalling radio bearer is established; after finishing the resource configuration, the target cell generates a radio resource control connection reconfiguration message comprising the signalling radio bearer and transmits the message to user equipment through a source cell; the user equipment carries out resource configuration, maintains a data radio bearer established in the coordinated process and establishes the signalling radio bearer. According to the invention, unnecessary steps are omitted, operations of repeated establishment and resource deletion are avoided and the efficiency of a terminal and a base station is improved.

Description

technical field [0001] The present invention relates to the technical field of digital communication, in particular to a wireless communication system and a method for optimizing resource allocation during cooperative set switching in the wireless communication system.
