Problems solved by technology

Therefore, this will make it impossible to use beamforming technology for the UE's newly added wireless links in other cells of the same Node B
Even if the reference channels of these newly added wireless links can be reconfigured by using the synchronous wireless link reconfiguration process, this will obviously increase the complexity of signaling control and the amount of signaling transmitted, increasing the processing complexity of the system
For RNSAP, since the SRNC cannot obtain the information of the reference channel of the newly added wireless link, it cannot correctly send the reference channel information of the corresponding wireless link to the UE, which will cause the UE to be unable to correctly receive the information of the corresponding wireless link.

Embodiment Construction

[0065] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0066] The application scenario of the first embodiment of the present invention is the wireless access network of the UMTS system, and the UE is currently in the Node B subordinate to the SRNC, and the SRNC is the CRNC. The specific process is as Figure 4 shown.

[0067] In step 410, the SRNC, acting as the CRNC, sends the "RADIOLINK ADDITION REQUEST" message in the NBAP protocol to the Node B, instructing the Node B to add a radio link for the UE, wherein the reference channel information of the new radio link is added. Specifically, as shown in Table 6, IE "Primary CPICH Usage For ChannelEstimation" (basic CPICH channel estimation usage) and IE "Secondary CPICH Information" (No. Two CPICH information). Wherein, the definitions and usages of these two IEs ar...

Abstract

The invention relates to a mobile communication field, discloses a method for adding a wireless link of a wirelss accessing network so that the added wireless link can adequately use a beamforming ability of a cell. In the invention, a reference channel used in the added wireless link is configured in a wireless link adding process of an NBAP. If the cell where the wireless link is located supports a beamforming technic, the reference channel of the wireless link can be configured as a special S-CPICH for beams, thereby adequately exerting a performance of an Node B supporting the beamforming function, effectively increasing system capacity. In addition, the reference channel used in the added wireless link is returned during a wireless link adding process of an RNSAP, so as to ensure a UE can accurately receives corresponding wireless link signals.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a base station node application part (Node-B Application Part, referred to as "NBAP") and a radio network subsystem application part (Radio Network Sub-system Application Part, referred to as "NBAP") related to the increase of wireless links RNSAP") technology. Background technique [0002] The Universal Mobile Telecommunications System ("UMTS") is a global system for mobile communications (Global System for Mobile communication, "GSM") network proposed by the European Telecommunications Standards Institute ("ETSI"). Solutions based on a smooth transition to the third generation of mobile communications. In essence, it is the third generation mobile communication system. [0003] UMTS is compatible with the existing legacy GSM system. The GSM system will transition to UMTS in stages. The General Packet Radio Service (GPRS) that has been launched now provides connec...
