Embodiment Construction

[0042] In the embodiment of the present invention, in order to reduce the access delay of the UE, it is considered that when the UE sends the RRC connection establishment request to the RNC, that is, the RRC connection establishment request carries the measurement results of the different system cells, so that the RNC can complete the RRC connection establishment. After that, the inter-system cell handover can be initiated immediately according to the measurement result of the different-system cell analyzed from the RRC connection establishment request, thereby omitting the waiting time for sending measurement control and measurement report, and reducing the UE access delay . To this end, before sending the RRC connection establishment request, the UE may measure the cells of the different system according to the measurement requirements of the cells of the different system in the system message broadcast by the cell.

Abstract

The invention discloses an intersystem cell switching method which comprises the following steps: measuring a different system cell according to a different system cell measuring requirement in a system message from a cell broadcast and reporting an obtained measuring result of the different system cell to a radio network controller (RNC) through a radio resource control (RRC) connection establishing request by using user equipment (UE); and resolving the measuring result of the different system cell from the RRC connection establishing request and initiating intersystem cell switching according to the measuring result of the different system cell after the establishment of RRC connection is completed by using the RNC. Moreover, the invention also discloses an intersystem cell switching system, the UE and the RNC. The technical scheme disclosed by the invention can reduce access delay of the UE.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a method and system for cell handover between systems, user equipment (UE) and radio network controller (RNC). Background technique [0002] In the early stage of TD-SCDMA system network construction, due to insufficient coverage and full use of 3G network for data service processing, pure AMR (voice service) users are usually directly switched to the 2G system, that is, for AMR users The mobile terminal (also called user equipment UE) performs inter-system handover after the radio link connection (Radio Resource Control [RRC] Connection) is established. [0003] In order to complete the above-mentioned inter-system handover, the UE needs to effectively report the measurement results of the neighboring cells of different systems, so that the network side can reasonably select the neighboring cells of different systems according to the measurement results reported by the ...
