Description
本公开涉及无线通信技术领域,例如涉及一种信令传输方法、装置、基站及终端。
在移动蜂窝网络中,为了能明确和便利地对终端进行管理和提供服务,终端通常连接到一个基站,这个基站是为该终端服务的基站。但是,随着用户对数据业务速率要求的不断提高,用户希望终端可以连接到超过一个的基站进行数据传输。在移动通信系统中,有两种类型的数据包,一种是控制信令,另一种是用户数据。控制信令和用户数据由于本身特点的不同,因此在进行传输时的要求也不同。控制信令的发送要求更高的可靠性,更低的误码率和丢包率,数据传输速率可以相对较低。用户数据的发送则要求更高的传输速率,更有效的编码和信道传输模式。因此,在终端和基站之间分别设置了两种不同的无线承载来传输这两类数据,使用信令无线承载(Signaling Radio Bearer,SRB)作为信令发送的承载,使用数据无线承载(Data Radio Bearer,DRB)作为用户数据发送的承载。
目前,相关技术提出针对用户数据的双连接技术,支持通过两个基站进行用户数据的发送和接收。但是,相关技术中还没有针对信令承载进行双连接的方案。信令承载和数据承载不同,信令承载的类型和个数是固定的,而数据承载可以根据实际的传输需求创建多个。此外,信令承载的不同类型分别处理不同类型的信令,这与数据传输存在本质不同。因此,为了提高信令传输的高可靠性,需要一种针对信令传输的双连接方案。

基站向终端发送无线资源控制协议(Radio Resource Control,简称RRC)信令,所述RRC信令中包含用于指示终端在信令无线承载上是否采用分离发送的方式发送信令数据的参数。
在本申请一实施例中,所述RRC信令可以包括:RRC连接重配置(Radio Resource Control Connection Reconfiguration)信令。

在本申请一实施例中,所述信令无线承载分离模式参数的取值包括以下中的一种:复制模式和独立模式。
其中,所述复制模式是指终端向主基站和辅基站发送相同的数据包,独立模式是指终端向主基站和辅基站发送不同的数据包。

2)SRB_Type:信令无线承载类型,用于指示终端是否使用SRB分离发送方式。当该参数值为Split时,表示终端与主基站通信建立的SRB需要采用分离发送的方式;当该参数值为MCG(Main Cell Group,主小区组)时,表示不需要采用分离发送的方式。分离发送的方式是指终端可以同时在两个基站,即主基站和辅基站上发送承载控制信令的数据包。

4)主基站RLC配置信息;
