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,所描述的实施例仅仅是本发明一部分实施例,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作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
本文中描述的技术可用于各种通信系统,如当前2G,3G通信系统和下一代通信系统,例如,全球移动通信(英文:Global System for Mobile communications,简称:GSM)系统,码分多址(英文:Code Division Multiple Access,简称:CDMA)系统,时分多址(英文:Time Division Multiple Access,简称:TDMA)系统,宽带码分多址(英文:Wideband Code Division Multiple Access Wireless,简称:WCDMA)系统,频分多址(英文:Frequency Division Multiple Addressing,简称:FDMA)系统,正交频分多址(英文:Orthogonal Frequency-Division Multiple Access,简称:OFDMA)系统,单载波 FDMA(SC-FDMA)系统,通用分组无线业务(英文:General Packet Radio Service,简称:GPRS)系统,长期演进(英文:Long Term Evolution,简称:LTE)系统,以及其他此类通信系统。
本文中结合终端和/或基站和/或基站节点来描述各种方面。
用户设备,可以是无线终端也可以是有线终端,无线终端可以是指向用户提供语音和/或数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(英文:Radio Access Network,简称:RAN)与一个或多个核心网进行通信,无线终端可以是移动终端,如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。例如,个人通信业务(英文:Personal Communication Service,简称:PCS)电话、无绳电话、会话发起协议(英文:Session Initiation Protocol,简称:SIP)话机、无线本地环路(英文:Wireless Local Loop,简称:WLL)站、个人数字助理(英文:Personal Digital Assistant,简称:PDA)等设备。无线终端也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station),移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、接入点(Access Point)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Equipment)。
基站(例如,接入点)可以是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备。基站可用于将收到的空中帧与IP分组进行相互转换,作为无线终端与接入网的其余部分之间的路由器,其中接入网的其余部分可包括网际协议(英文:Internet Protocol,简称:IP)网络。基站还可协调对空中接口的属性管理。例如,基站可以是GSM或CDMA中的基站(英文:Base Transceiver Station,简称:BTS),也可以是WCDMA中的基站(NodeB),还可以是LTE中的演进型基站(英文:evolutional Node B,简称:NodeB 或eNB或e-NodeB),本申请并不限定。
另外,本文中术语“系统”和“网络”在本文中常被可互换使用。
众所周知,如图1所示,D2D技术是一种端到端直接通信的技术,其不仅能够分担移动通信网络繁重的网络负荷、卸载蜂窝业务,而且基于近距离通信的天然优势,其还可以提升移动通信网络的频谱效率,并能够使得移动通信网络获得较高的吞吐性能和较低的传输时延,因此,D2D技术已成为了本领域技术人员研究的重点课题。
但是在现有的D2D技术中,UE在采用广播或组播模式进行数据传输时,仅支持单跳的传输方式,而这种传输方式会导致由发送端发出的数据包的传输范围非常有限,从而在很大程度上限制了D2D技术的应用范围和应用场景。例如,在移动本地广告(英文:mobile local advertisement)场景下,零售商需通过采用D2D技术的用户设备广播自身的打折信息,但是,由于现有D2D技术仅支持单跳的传输方式,其广播的覆盖范围只有一跳,也就是说,仅能从源节点将打折信息广播至其他节点,接收到打折消息的其他节点不再进行转发,这样的传输方式使得广告的广播范围极为有限,从而影响了广告的效果。再例如,在社交应用(英文:social application)场景下,UE通过D2D应用广播自身的交友需求,在这种情况下,也会由于现有D2D技术仅支持单跳的传输方式使得广播范围受到限制,从而导致找到相同兴趣的好友的概率降低。
采用本发明提供的数据传输方法,可以很好的解决上述问题。并且,为了便于本领域技术人员的理解,本发明通过以下实施例对本发明提供的技术方案的具体实现过程进行说明。
本发明一实施例提供一种数据传输方法,如图2所示,该方法可以包括:

示例性的,在UE1需采用广播模式向周围的UE2发送数据包时,UE1可以将最大跳数携带在数据包中向周围的UE2进行广播,此时,在周围的UE2接收到数据包之后,可以先判断该数据包中是否携带有最大跳数,若确定出该数据包中携带有最大跳数,则将该最大跳数减一,并继续将该数据包进行转发广播,其中转发广播的数据包中携带有减一后得到的跳数,直到接收到数据包的UE确定数据包中携带的跳数为0时,停止数据包的转发广播。
