Embodiment Construction

[0107] The present invention provides a downlink radio bearer mapping method for radio access bearers in the PS domain, the core of which is: when constructing the corresponding IP message bearer structure through the initial call connection establishment process of the PS domain, establish the PDP The context and the corresponding radio access bearer RAB, and downlink mapping the RAB corresponding to the PDP context to the high-speed downlink shared channel HS-DSCH.

[0108] The first embodiment provided by the present invention corresponds to the case where the received IP message is distributed by the GGSN and transmitted to the corresponding RAB, and the priority of the message is distinguished by the PDCP layer. The main idea is: when constructing the corresponding IP packet bearer structure through the call connection establishment process of the initial packet-switched PS domain, establish a primary PDP context and a secondary PDP context between the UE and the RNC, and ...

Abstract

The related down mapping method for RAB comprises: when constructing IP message load structure according to initial PS calling connection, first building DPD text and relative RAB, and down mapping RAB of PDP text to HS-DSCH; then, transferring IP message based on of RAB. This invention can provide proper bandwidth to adapt IP network feature, reduces waste and delay, and decreases or eliminates different conflicts.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for downlink mapping of radio access bearers in a packet switching domain. Background technique [0002] In a Wideband Code Division Multiple Access (WCDMA) system, access and transmission of a broadcast domain (BC), a circuit switched domain (CS) and a packet switched domain (PS) are provided. The BC domain is used to provide broadcasting in the system, the CS domain is used to provide access and transmission of circuit-switched services, and the PS domain is used to provide access and transmission of packet services (mainly IP packets) . The network structure of the WCDMA system is as shown in Figure 1, including: [0003] User equipment (UE), UMTS system terrestrial radio access network (UTRAN), core network (CN) and extranet. The CN includes GGSN and SGSN; the UTRAN includes a radio network controller (Radio Network Controller; RNC) and a system base station (Nod...
