获得无线通信系统中的通信会话发起信息

Obtaining communication session initiation information in wireless communications system

Abstract

在一实施例中,用户装备(UE)(200;1100)接收(405A;505A;505B;505C;710A;710B;710C;815;915;1015)在该UE处于休眠状态(例如,URA_PCH或CELL_PCH)时建立给定类型的通信会话的请求。该UE配置(410A;510A;510B;510C;715A;715B;715C;820;920;1020)状态转换请求消息(例如,蜂窝小区更新消息)以便:(i)请求接入网将该UE从休眠状态转换至目标状态(例如,CELL_FACH或CELL_DCH),并且获得网络指派的因服务蜂窝小区而异的标识符(例如,C-RNTI),以在该UE与该服务蜂窝小区之间交换与所述给定类型的通信会话相关联的数据,以及(ii)指示所述给定类型的通信会话。该UE向接入网传送(415A、515A、515B、515C、720A、720B、720C、825、925、1025)所述状态转换请求消息,以及该接入网基于该状态转换请求消息来确定(410B、520A、520B、520C、725A、725B、725C、830、930、1030)该给定类型的通信会话。
In an embodiment, a user equipment (UE) (200; 1100) receives (405A; 505A; 505B; 505C; 710A; 710B; 710C; 815; 915; 1015) request to set-up a communication session of a given type while the UE is in a dormant state (e.g., URA_PCH or CELL_PCH). The UE configures (410A; 510A; 510B; 510C; 715A; 715B; 715C; 820; 920; 1020) a state transition request message (e.g., a cell update message) (i) to request that an access network transition the UE from the dormant state to a target state (e.g., CELL_FACH or CELL_DCH) and to obtain a network-assigned serving cell-specific identifier (e.g., C-RNTI) for exchanging data between the UE and the serving cell in association with the communication session of the given type and (ii) to indicate the given type of the communication session. The UE transmits 415A; 515A; 515B; 515C; 720A; 720B; 720C; 825; 925; 1025) the state transition request message to the access network, and the access network determines (410B; 520A; 520B; 520C; 725A; 725B; 725C; 830; 930; 1030) the given type of the communication session based on the state transition request message.
