Description

一种进行业务传输的方法和终端
本申请要求在2016年4月25日提交中国专利局、申请号为201610264240.1、发明名称为“一种进行业务传输的方法和终端”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本发明涉及无线通信技术领域,特别涉及一种进行业务传输的方法和终端。
背景技术
3GPP(3rd Generation Partnership Project,第三代移动通信标准化组织)中,D2D(设备到设备)接近服务不同于传统的蜂窝网络通信。对于传统蜂窝网络通信,所有数据传输都需要经过网络;而对于D2D,终端之间可以建立直接通信的链路,如图1所示。
D2D包括以下两大类:
D2D Discovery(接近服务发现):UE(终端)使用E-UTRA(演进的通用移动通信系统陆地无线接入网络)来确认另外一个UE在其附近。例如,D2D UE可以使用该服务来寻找附近的出租车、寻找在其附近的朋友等。在3GPP系统中D2D链路也称为Sidelink,因此D2D Discovery也称为Sidelink Discovery。
D2D Communication(接近服务通信):相互接近的UE,通过在两个UE之间直接建立链路(如图1所示),这样将原本通过网络传输的通信链路转化为本地的直接通信链路,节省了大量的带宽和网络效率;或者两个相互接近的UE,可以利用直接链路通信来获得稳定高速低廉的通信服务。接近服务通信一般是在网络侧控制或者辅助下进行的,eNB(演进基站)甚至可能会为进行接近服务通信的UE动态的分配资源。在3GPP系统中D2D链路也称为Sidelink,因此D2D Communication也称为Sidelink Communication。
参与D2D Discovery/Communication的UE分为两种角色:
D2D发送UE:即发送D2D Discovery/Communication消息的UE;
D2D接收UE:即接收D2D发送UE发送的D2D Discovery/Communication消息的UE。
对于R13以及之前版本的D2D接收UE,UE根据系统广播或者预配置的D2D接收资源池进行D2D Discovery或者Communication信号的接收。系统广播或者预配置的D2D接收资源池由于要包含所有D2D发送UE的D2D发送资源池,因此一般会比较大,这样D2D接收UE就需要持续监听系统广播或者持续监听预配置的D2D接收资源,非常费电。
综上所述,目前D2D接收UE需要持续监听系统广播或者持续监听预配置的D2D接收资源,耗电量很大。

具体实施方式
本发明实施例进行直接通信的终端根据DRX配置及标识信息确定激活时间,所述激活时间位于没有业务传输的时间段内,使得进行直接通信的终端只需要在激活时间之后开启收发机,从而不需要持续监听系统广播或者持续监听预配置的D2D接收资源,节省了电量。
为了使本发明的目的、技术方案和优点更加清楚,下面将结合附图对本发明作进一步地详细描述,显然,所描述的实施例仅仅是本发明一部份实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有 其它实施例,都属于本发明保护的范围。
如图2所示,本发明实施例进行业务传输的方法包括:
步骤200、直接通信的终端根据DRX配置和标识信息,确定激活时间,所述激活时间位于没有业务传输的时间段内;
步骤201、所述终端在所述激活时间之后开启收发机,用于进行直接通信业务传输。
在实施中,为了更好地适应不同的应用场景,可以根据是否配置DRX,确定是否采用本发明实施例的方案。
具体的,直接通信的终端如果确定已配置DRX,则采用本发明实施例的方案;否则可以采用现有的方案,也可以采用其他方案。
其中,本发明实施例的终端是具有直接通信接口的终端。
可选的,所述终端在所述激活时间之后开启收发机时,可以在所述激活时间之后的第N个资源调度周期开启收发机进行业务传输;其中,N为正整数,比如N为1。
具体N的值可以根据需要、经验、仿真等方式确定。后续在应用过程中也可以对N的值进行调整。
在实施中,如果N为1,有可能出现一种情况是激活时间与第1个资源调度周期的起始时间相同,如果出现个这种情况,则在激活时间到达后可以立即开启收发机。
如果所述终端对应多个资源池,则所述终端在所述激活时间之后的每个资源池对应的第N个资源调度周期开启收发机。
其中,本发明实施例的直接通信业务包括但不限于下列业务中的部分或全部:
一对多的组通信业务、一对一的通信业务、发现业务。
