Method of setting up master call

Abstract

The method comprises: a) the users equipment (UE) needing to build a calling sends a request for building connection of radio resources control (RRC) to the serving radio network controller (SRNC) through an random access channel (RACH) of the existed public channels; b) the serving radio network subsystem (SRNS) sends RRC building message carrying RRC connection building message to the UE through the forward access channel (FACH) of the existed public channels; c) according to RRC connection building message, after the UE builds the RRC connection, it sends a message of completing the RRC build through RACH; d) after building a connection of non-access stratum (NAS)signaling between the UE and the core network (CN) and completing the assignation of radio access bearer (RAB), the build of UE calling is completed.

Description

Technical field [0001] The present invention relates to a technology for establishing a call under a wideband code division multiple access (WCDMA) system or a time division synchronous code division multiple access (TD-SCDMA) system, and particularly relates to a call establishment under a WCDMA system or a TD-SCDMA system Methods. Background technique [0002] With the development of wireless communication technology, WCDMA and TD-SCDMA, as the mainstream third-generation (3G) communication standards, have gradually received widespread attention. [0003] At present, the process of establishing a calling party for WCDMA or TD-SCDMA is as follows: figure 1 As shown, the network entities involved in the procedure for establishing a calling party include: the user equipment (UE) that initiates the calling party establishment, the serving radio network subsystem (NodeBSRNS) of the Node B to which the UE belongs, and the serving radio network controller (SRNC) governing the NodeBSR...

AI Technical Summary

Problems solved by technology

[0008] use figure 1 Described process establishes caller, although can set up relatively safe and reliable caller, the process of caller establishment is longer: at first, SRNC needs to re-establish wireless link and Iub interface between SRNC and NodeBSRNS in RRC connection establishment process The data transmission link, and the physical layer synchronization is required to confirm that the RRC connection is successfully established, which takes a long time; secondly, during the establishment of the NAS signaling connection between the UE and the CN, between the UE and the CN The interaction of direct transmission messages has been carried out many times, and each interaction of direct transmission messages takes a long time; finally, during the RAB assignment process, the wireless link, the data transmission link of the Iub interface and the Iu interface need to be re-established data transmission link, which also takes a long time
