Problems solved by technology

That is to say, the RADIO LINK ADDITIONRESPONSE / RADIO LINK ADDITION FAILURE message structure of the current 433 protocol is flawed, and NODEB cannot correctly inform the RNC of the current user link status, which makes the signaling processing of the IUB port (interface between RNC and Node B) incorrect

Embodiment Construction

[0047] The basic principle of the present invention is: in the mobile communication handover, in the case of needing to perform softer merger and need to report RNC establishment / increase of related services, change the way that the existing 433 protocol notifies RNC through RL ADDITION signaling, that is, simultaneously notifies RNC Softer combination and establishment of E-DCH service related information, specifically by carrying the DCH softer combination information and adding E-DCH service information not in the same diversity indication selection field in the RADIO LINK ADDITION RESPONSE message to notify the radio network controller ; or notify the radio network controller by simultaneously carrying the DCH softer combination information and adding E-DCH service information in the Combining field under the diversity indication selection field in the RADIO LINK ADDITION RESPONSE message.

[0048] The present invention will be described in detail below in conjunction with ...

Abstract

The invention discloses a mobile communication handoff method and system, base station thereof. The method comprises steps: based on the first link only bearing DCH service, increasing the second link for bearing DCH and E-DCH services; softer combining the DCH service of the first and the second links; carrying the DCH softer combining information which selects fields in different diversities in the RADIO LINK ADDITION FAILURE message and adding E-DCH service messages to notify a radio network controller. The invention can improve mobile communication handoff success rate to keep communication services continuously.

Description

technical field [0001] The present invention relates to a communication method, a system thereof, and a base station, in particular to a mobile communication switching method, a system thereof, and a base station. Background technique [0002] Referring to Fig. 1, the wireless network related to cell handover in the prior art includes a radio network controller (RNC.Radio Network Controller) 110, a node (NODEB, a base station of a WCDMA system) 120, and a user terminal (UE, User Equipment) under the node 120 140. When the UE 140 is handed over between the cells 130, the node 120 notifies the RNC 110 of adding related information in a radio link addition (RADIO LINK ADDITION, RLADDITION) signaling process. [0003] Referring to FIG. 2, in a prior art handover situation, the process of performing DCH / E-DCH (Enhanced UL DCH, enhanced uplink dedicated channel) service handover between cells 130 includes the following steps: [0004] 201. In phase 1, UE140 establishes radio lin...
