具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明的一部分实施例，而不是全部实施例。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的前提下所获得的所有其他实施例，都应属于本发明保护的范围。
应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
本发明实施例的方案可以应用于现有的蜂窝通信系统，如全球移动通讯(英文全称可以为：Global System for Mobile Communication，英文简称可以为：GSM)，宽带码分多址(英文全称可以为：Wideband Code Division Multiple Access，英文简称可以为：WCDMA)，长期演进(英文全称可以为：Long Term Evolution，英文简称可以为：LTE)等系统中，所支持的通信主要是针对语音和数据通信的。通常来说，一个传统基站支持的连接数有限，也易于实现。
下一代移动通信系统将不仅支持传统的通信，还将支持机器到机器(英文全称可以为：Machine to Machine，英文简称可以为：M2M)通信，或者叫做机器类型通信(英文全称可以为：Machine Type Communication，英文简称可以为：MTC)通信。根据预测，到2020年，连接在网络上的MTC设备将会达到500到1000亿，这将远超现在的连接数。对M2M类业务，由于其业务种类千差万别，对网络需求存在很大差异。大致来说，会存在如下几种需求：
可靠传输，但对时延不敏感；
低延迟，高可靠传输。
对可靠传输，但对时延不敏感业务，较容易处理。但是，对低延迟、高可靠传输类的业务，不仅要求传输时延短，而且要求可靠，比如设备到设备(英文全称为：Device to Device，英文简称可以为：D2D)业务。如果传输不可靠，会导致重传而造成传输时延过大，不能满足要求。由于大量连接的存在，使得未来的无线通信系统和现有的通信系统存在很大差异。大量连接需要消耗更多的资源接入终端设备以及需要消耗更多的资源用于终端设备的数据传输相关的调度信令的传输。根据本发明实施例的方案能够有效解决上述资源消耗问题。
图1是本发明实施例的应用的无线通信系统100的示意图，该无线通信系统100包括可以包括至少一个网络设备110。网络设备可以是网络设备等用于与移动设备通信的设备，网络设备可以是WLAN中的接入点(英文全称为：Access Point，英文简称可以为：AP)，GSM或码分多址CDMA(英文全称为：Code Division Multiple Access，英文简称可以为：CDMA)中的基站(英文全称为：Base Transceiver Station，英文简称可以为：BTS)，也可以是WCDMA中的基站(英文全称为：NodeB，英文简称可以为：NB)，还可以是LTE中的或演进型基站(英文全称为：Evolutional Node B，英文简称可以为：eNB或eNodeB)，或者中继站或接入点，或者车载设备、可穿戴设备以及未来5G网络中的终端设备或者未来演进的PLMN网络中的网络设备等。
该无线通信系统100还包括位于网络设备110覆盖范围内的多个终端设备120。该终端设备120可以是移动的或固定的。该终端设备120也可以称为用户设备(英文全称为：User Equipment，英文简称可以为：UE)、接入 终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备可以是无线局域网(英文全称为：Wireless Local Area Networks，英文简称可以为：WLAN)中的站点(英文全称为：STATION，英文简称可以为：ST)，可以是蜂窝电话、无绳电话、会话启动协议(英文全称为：Session Initiation Protocol，英文简称可以为：SIP)电话、无线本地环路(英文全称为：Wireless Local Loop，英文简称可以为：WLL)站、个人数字处理(英文全称为：Personal Digital Assistant，英文简称可以为：PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及未来5G网络中的终端设备或者未来演进的公共陆地移动网络(英文全称为：Public Land Mobile Network，英文简称可以为：PLMN)网络中的终端设备等。
图1示例性地示出了一个网络设备和六个终端设备，可选地，该无线通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备，本发明实施例对此不做限定。此外，该无线通信系统100还可以包括移动管理实体(Mobile Management Entity，MME)、服务网关(Serving Gateway，S-GW)、分组数据网络网关(Packet Data Network Gateway，P-GW)等其他网络实体，但本发明实施例不限于此。
具体地，终端设备120可以以蜂窝通信模式或D2D通信模式进行通信，其中，在蜂窝通信模式中，终端设备可以通过网络设备与其它终端设备通信；在D2D通信模式中，终端设备可以通过D2D链路直接与其它终端设备通信。
在图1示出的多个终端设备120中，包括蜂窝终端设备、D2D终端设备和中继终端设备，其中，蜂窝终端设备采用蜂窝通信技术(即，第二通信协议所规定的通信技术的一例)与网络设备110进行通信。D2D终端设备通过中继终端设备实现与网络设备之间的数据传输，其中，中继终端设备与D2D终端设备之间具有例如，PC5接口，采用D2D通信技术(即，第二通信协议所规定的通信技术的一例)进行通信，其中，该D2D通信技术可以具体为LTE中的旁路(SL，SideLink)技术，也可以为WLAN中的WIFI或蓝牙等技术，或者为其它D2D通信技术，本发明实施例对此不做限定。中继终端设备与网络设备之间具有例如，Uu接口，采用蜂窝通信技术进行通信。
可选地，该远端设备处于该网络设备的覆盖范围外，该中继终端设备处于该网络设备的覆盖范围内。
在本发明实施例中，通信系统100中的各设备中设置有用于实现无线通信的协议栈(Protocol Stack)，并且，各设备中的协议栈可以相同也可以相异本发明并未特别限定。
作为示例而非限定，在本发明实施例中该协议栈可以是LTE等4G网络中使用的协议栈，也可以是未来的5G网络使用的协议栈，也可以是用于D2D通信的协议栈(例如，WLAN中的WIFI或蓝牙等技术所使用的协议栈)，本发明并未特别限定。以下，为了便于理解和区分，以LTE中规定的协议栈为例，进行说明。
协议栈是指网络中各层协议的总和，其形象的反映了一个网络中文件传输的过程：由上层协议到底层协议，再由底层协议到上层协议。作为实例而非限定，在本发明实施例中，无线通信所使用的协议栈可以包括以下至少一个协议层或多个协议层的组合，每层协议都可以存在多种协议实体，作为示例而非限定，本发明实施例中的协议栈可以包括以下一种或多种协议层：
