Description

添加辅小区的方法、 装置、 设备和网络系统 技术领域
本发明涉及无线通信技术， 尤其涉及一种添加辅小区的方法、 装置、 设 备和网络系统。 背景技术
一种网络部署已经被引入到下一代无线网络中， 在这种部署中一个基 站有两种不同频率的小区， 终端可以同时和一个基站的两个不同频率的小 区保持连接。 同时和一个终端保持连接的小区中有一个为主小区， 另外一 个为辅小区。 图 1为现有技术网络系统信令示意图； 如图 1所示， 终端与 基站的通信可分为以下几个步骤： 首先， 基站在主小区上向终端发送随机 接入资源分配消息， 该消息包括随机接入导频码序号和物理随机接入信道 (Physical Random Access Channel, 以下简称： PRACH )掩码序号， 该消 息使用小区无线网络临时标识 （ Cell Radio Network Temporary Identifier, 以下简称： C-RNTI )对随机接入资源分配消息加扰；其次 ,终端应用 C-RNTI 对接收的随机接入资源分配消息解扰后， 根据其接收到的随机接入资源分 配消息在辅小区上向基站发送随机接入请求消息， 该随机接入请求消息包 括随机接入导频码； 再其次， 基站根据接收到的随机接入请求消息在主小 区上向终端发送随机接入响应消息， 该随机接入响应消息包括时间提前命 令 TAC(Time Advance Command,以下简称： TAC); 最后， 终端根据基站 发送的随机接入响应消息调整自身在辅小区上的提前时间 （ Time Advance, 以下简称： TA ) 。
在实际的网络部署中， 主小区和辅小区也可能属于不同的基站， 主小 区所属的基站称为主基站， 辅小区所属的基站称为辅基站， 图 2为在现有 技术下可能出现的网络系统信令示意图； 如图 2所示， 系统整体通信的过 程为： 首先， 主基站向终端发送随机接入资源分配消息， 其次， 终端向辅 基站发送随机接入请求消息，最后，主基站向终端发送随机接入响应消息。
在实现本发明过程中， 发明人发现当出现主小区和辅小区虽有连接， 但该连接的时延比较大， 并且容量也比较小的时候， 就会出现无法进行正 常通信的情况， 该情况具体为如图 2所示， 第一， 辅基站不知道主基站发 送给终端的随机接入资源分配消息是什么而导致不能正确接收随机接入 请求消息； 第二， 主基站不知道辅基站什么时候接收到了来自终端发送的 随机接入请求消息，而无法确定何时给终端发送随机接入响应消息，第三， 因主基站不知道终端发送给辅基站的随机接入请求消息内容而无法正确 发送随机接入响应消息给终端。 发明内容
