技术领域technical field
本发明涉及通信领域，尤其涉及一种数据传输方法、网络设备及用户设备。The present invention relates to the communication field, in particular to a data transmission method, network equipment and user equipment.
背景技术Background technique
随着移动通信技术的不断发展，长期演进(英文：Long TermEvolution，简称：LTE)已成为目前主流的无线通信技术，其中的设备到设备(英文：Device to Device，简称：D2D)技术已被作为重要特性且进行了标准化工作。D2D技术是一种端到端直接通信的技术，其与传统的蜂窝通信技术最大的不同在于，采用D2D技术的用户设备(英文：UserEquipment，简称：UE)之间不再需要基站的中转便可以直接进行通信。另外，随着社会的不断发展，移动通信网络中UE的数量也在急剧的增长，这无疑大大增加了移动通信网络的网络负荷。此时，D2D技术由于其独特的优势，成为了减小移动通信网络负荷的首选技术。With the continuous development of mobile communication technology, Long Term Evolution (English: Long Term Evolution, referred to as: LTE) has become the current mainstream wireless communication technology, and the device-to-device (English: Device to Device, referred to as: D2D) technology has been used as Important features and standardization work has been carried out. D2D technology is an end-to-end direct communication technology. The biggest difference between it and the traditional cellular communication technology is that the user equipment (English: User Equipment, referred to as: UE) using D2D technology no longer needs the transfer of the base station. communicate directly. In addition, with the continuous development of society, the number of UEs in the mobile communication network is also increasing rapidly, which undoubtedly greatly increases the network load of the mobile communication network. At this time, due to its unique advantages, the D2D technology has become the preferred technology for reducing the load of the mobile communication network.
在现有技术中，采用D2D技术的UE在采用广播或组播模式进行数据传输时，主要采用的是单跳传输方式，具体的是，发送端采用广播或组播模式将数据包传输至接收端之后，接收端不会继续将接收到的数据包进行转发。In the prior art, when the UE using D2D technology adopts the broadcast or multicast mode for data transmission, it mainly adopts the single-hop transmission mode. Specifically, the sending end uses the broadcast or multicast mode to transmit the data packet to the receiver After the end, the receiving end will not continue to forward the received data packets.
现有技术中至少存在如下问题：由于采用D2D技术的UE采用的是单跳传输方式进行数据传输的，这样会使得由发送端发出的数据包的传输范围非常有限，从而限制了D2D技术的应用范围和应用场景。There are at least the following problems in the prior art: since the UE adopting the D2D technology uses a single-hop transmission method for data transmission, this will make the transmission range of the data packet sent by the sender very limited, thereby limiting the application of the D2D technology scope and application scenarios.

本文中结合终端和/或基站和/或基站节点来描述各种方面。Various aspects are described herein in connection with terminals and/or base stations and/or base station nodes.
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(RemoteTerminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Equipment)。The user equipment may be a wireless terminal or a wired terminal. The wireless terminal may be a device that provides voice and/or data connectivity to the user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem. The wireless terminal can communicate with one or more core networks via a radio access network (English: Radio Access Network, RAN for short), and the wireless terminal can be a mobile terminal, such as a mobile phone (or called a "cellular" phone) and a The computer of the mobile terminal, which may be, for example, a portable, pocket, hand-held, built-in computer or vehicle-mounted mobile device, exchanges language and/or data with the radio access network. For example, personal communication service (English: Personal Communication Service, abbreviated: PCS) telephone, cordless telephone, session initiation protocol (English: Session Initiation Protocol, abbreviated: SIP) telephone, wireless local loop (English: Wireless Local Loop, abbreviated: WLL) station, personal digital assistant (English: Personal Digital Assistant, referred to as: PDA) and other equipment. A wireless terminal can also be called a system, a subscriber unit (Subscriber Unit), a subscriber station (Subscriber Station), a mobile station (Mobile Station), a mobile station (Mobile), a remote station (Remote Station), an access point (Access Point), Remote Terminal (RemoteTerminal), Access Terminal (Access Terminal), User Terminal (User Terminal), User Agent (User Agent), User Equipment (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。A base station (eg, access point) can refer to a device in an access network that communicates with wireless terminals over the air interface through one or more sectors.

For example, the base station may be a base station (English: Base Transceiver Station, BTS for short) in GSM or CDMA, may also be a base station (NodeB) in WCDMA, or may be an evolved base station (English: evolutional Node B, Abbreviation: NodeB or eNB or e-NodeB), which is not limited in this application.
另外，本文中术语“系统”和“网络”在本文中常被可互换使用。Additionally, the terms "system" and "network" are often used herein interchangeably.
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。As we all know, as shown in Figure 1, D2D technology is an end-to-end direct communication technology, which can not only share the heavy network load of the mobile communication network and unload cellular services, but also based on the natural advantages of short-distance communication, it can also improve The spectrum efficiency of the mobile communication network can enable the mobile communication network to obtain higher throughput performance and lower transmission delay. Therefore, the D2D technology has become a key research topic for those skilled in the art.
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：socialapplication)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。However, in the existing D2D technology, when the UE uses the broadcast or multicast mode for data transmission, it only supports a single-hop transmission mode, and this transmission mode will result in a very limited transmission range of the data packet sent by the sender. Therefore, the application range and application scenarios of the D2D technology are limited to a large extent. For example, in the mobile local advertisement (English: mobile local advertisement) scenario, retailers need to broadcast their own discount information through user equipment using D2D technology. However, since the existing D2D technology only supports single-hop transmission, the broadcasted The coverage is only one hop, that is to say, the discount information can only be broadcast from the source node to other nodes, and other nodes that receive the discount information will not forward it again. This transmission method makes the broadcast range of advertisements extremely limited, thus affecting The effectiveness of advertising. For another example, in a social application (English: social application) scenario, the UE broadcasts its own friendship needs through the D2D application. In this case, the broadcast range is limited because the existing D2D technology only supports a single-hop transmission mode. As a result, the probability of finding friends with the same interests is reduced.
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。The above-mentioned problems can be well solved by adopting the data transmission method provided by the present invention.
