Description

服务节点建立方法和设备 技术领域
本发明实施例涉及通信技术领域,尤其涉及一种服务节点建立方法和设备。
背景技术
目前,车辆可以通过车辆与路边基础设施通信(vehicle to infrastructure,V2I)或者车辆与车辆之间通信(vehicle to vehicle,V2V)来及时获取路况信息或接收信息服务,可以将V2V/V2I通信所使用的网络称为车联网。其中,V2V/V2I信息可以通过长期演进(long term evolution,LTE)网络来传输,上述的车联网可以称为基于LTE的车联网。基于LTE的车联网可以将网络分为宏网络和微网络,如图1所示,演进型基站(evolved node B,eNB)控制宏网络,服务节点控制微网络;当车辆进入宏网络覆盖的区域时,eNB通过广播信息或发送无线资源控制(Radio Resource Control,RRC)信令等方式向车辆提供服务节点的接入信息,以使车辆可以根据该接入信息接入服务节点并驻留到微网络,服务节点负责车辆的传输资源分配,然后车辆可以通过微网络的传输资源进行V2I/V2V通信。
然而,当车辆进入至无服务节点覆盖的区域时,车辆以自由竞争的方式选择时频资源来用于进行V2I/V2V通信,这样存在多个车辆选择同一时频资源来进行通信的情况,产生传输时频资源碰撞的问题,从而造成V2I/V2V通信失败。
