Method for processing service bearing while communication system sponsor service request

Abstract

The present invention discloses service loaded processing method in communication system originating service request. It contains A, configuring service bearing configuration item and corresponded identification in terminal and access network; in terminal side establishing said service bearing identification service type mapping relation; B, terminal originating service request, notifying access network current request service type mapped service bearing; C, access network finding said service bearing corresponded service bearing configuration item, according to service request executing to said service bearing establishment or reconfiguration process. Said invention can effectively shorten service request switching time delay.

Description

Technical field [0001] The invention relates to a service call processing technology of a communication system, in particular to a method for processing service bearers when a communication system initiates a service request. Background technique [0002] Connection delay is an important issue in wireless communication systems, especially third-generation wireless communication systems, such as wideband code division multiple access (WCDMA) systems. Excessive connection delay will directly affect users’ subjective feelings and affect users’ communication operations Online loyalty. [0003] In the existing WCDMA technical solutions of the Third Generation Partnership Project (3GPP), service establishment is generally divided into two stages, one is the establishment of an RRC connection, and the other is the establishment of a radio bearer RB. In order to maintain the flexibility when establishing a service, the access network sends all relevant parameters through the air interfac...

Problems solved by technology

[0019] However, the existing RRC connection request message does not have an information element used to identify the established RB, and the UE cannot immediately notify the UTRAN of the RB type that the current service wants to handle. The UTRAN needs to wait until the UE and the CN negotiate, and the CN will send it Only when the radio access bearer (RAB) assignment message reaches UTRAN, UTRAN can complete the mapping from RAB to RB according to the assignment of the message, learn the RB information to be established or reconfigured by UE, start RB resource preparation, and send corresponding message to

[0020] The UE can complete the RB establishment or reconfiguration process; therefore, the resource preparation and establishment of the prior art RB is limited by when the UTRAN receives the RAB assignment from the CN, resulting in a long connection delay for existing service request calls
