Description

一种上行数据处理的方法及装置 技术领域
本发明涉及无线通信领域，特别涉及长期演进(LTE：Long Term Evolution)系统内站间切换过程中启动全配置full configuration时对于上行数据的处理方法及装置。
背景技术
图1是现有技术提供的上行数据处理的传统识别X2切换请求的full configuration切换流程图，如图1所示，当用户设备(UE：User Equipment)从高版本的基站切换或者重建立到低版本的基站中，低版本的基站无法知道UE当前的配置情况。这种情况下，目标基站D-ENB可以通过下发full configuration(通过切换请求响应携带full configuration标识给源侧基站S-ENB，并由源侧基站S-ENB通过下发切换命令原封不变给UE)，来让UE清空在源侧基站S-ENB下的专用资源配置，防止出现不可预期的异常。
UE在收到full configuration的无线资源控制协议重配置(RRCConnection Reconfiguration：Radio Resource Control Connection Reconfiguration)的配置消息时，必须清空所有专用资源包括测量配置和其他配置Otherconfig，但是必须保留小区无线网络临时识别(CRNTI：Cell Radio Network Temmporary Identify)/安全参数/无线链路控制(RLC：Radio Link Control)/分组数据汇聚协议(PDCP：Packet Data Convergence Protocol)/逻辑信道配置以保证后续可能的重建立流程。
在确认模式AM下，切换过程中由源侧在接到数据反传请求后上行不连续的数据都需要反传到目标侧。终端由高版本的基站切换到低版本的基站，则目标基站即低版本的基站，通过判断需要启动full configuration配置，以防止出现不可预期的异常，对于上行数据的处理，目标侧基站则是可以丢弃也可以直接把反传数据进行投递到服务网关(SGW：Service Gateway)。但是，在终端由高版本基站切换到低版本基站过程中，目标站启动了full configuration配置，则源侧对于上行报文反传到目标侧，而目标侧或者是丢弃 或者是直接投递给服务网关，这样就浪费了X2接口的带宽，也增加了源侧基站和目标侧基站无谓的处理流程给系统带来了额外开销。
发明内容
