Description

设备到设备D2D通信配置资源的处理方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种设备到设备D2D通信配置资源的处理方法及装置。
背景技术
随着无线多媒体业务的发展，人们对高数据速率和用户体验的需求日益增长，从而对传统蜂窝网络的系统容量和覆盖提出了较高要求。另一方面公共安全、社交网络、近距离数据共享、本地广告等应用场景使得人们对了解附近人或事物并与之通信邻近服务(Proximity Services，简称为PS)的需求逐渐增加。传统的以基站为中心的蜂窝网络在高数据速率以及邻近服务的支持方面存在明显的局限性，在这种需求背景下，代表未来通信技术发展新方向的设备到设备(Device-to-Device，简称为D2D)技术应运而生。D2D技术的应用，可以减轻蜂窝网络的负担、减少用户设备的电池功耗、提高数据速率，并改善网络基础设施的鲁棒性，很好地满足上述高数据速率业务和邻近服务的要求。
D2D技术可以工作在授权频段或非授权频段，允许多个支持D2D功能的用户设备(即D2D用户设备，D2D UE)在有网络基础设施或无网络基础设施的情况下进行直接发现/直接通信。D2D的应用场景主要有三种：
UE1和UE2在蜂窝网络的覆盖下进行数据交互，用户面数据不经过网络基础设施，图1是相关技术中设备直通系统发现/通信示意图，如图1的模式1；在弱/无覆盖区域的UE中继传输，如图1中的模式2，允许信号质量较差的UE4通过附近有网络覆盖的UE3与网络进行通信，能帮助运营商扩展覆盖、提高容量；在发生地震或紧急情况，蜂窝网络不能正常工作的情况下，允许设备间直接通信，如图1中的模式3，UE5，UE6和UE7间控制面和用户面都不经过网络基础设施而进行一跳或多跳的数据通信。
D2D技术通常包括D2D发现技术和D2D通信技术，其中，D2D发现技术是指用于判断/确定第一用户设备是否邻近第二用户设备的技术。通常，D2D用户设备间可通过发送或接收发现信号/信息来发现对方；D2D通信技术是指D2D用户设备之间部分或全部通信数据可以不通过网络基础设施而直接进行通信的技术。
基于D2D技术的以上特点和优势，现有技术已经提出使用蜂窝无线通信以及D2D技术来实现车联网应用的可能，支持通信的主要场景包括即时通信和车辆预警两个方面。车辆预警可能会包括碰撞预警、变道预警等，但这种场景下对时延的要求非常高，现有的D2D技术无法实现。
车联网通信中，许多场景下车辆与车辆之间的通信即车车通信(Vehicle to Vehicle，简称为V2V)需要满足低时延和高可靠的指标要求。比如：两辆车之间距离(如：车A和车B) 太近，需要注意车之间的行车安全。如果：车A先将其自身的位置/车速等信息报告给网络，再由网络通知车B，则车B获得车A的位置/车速等信息有延时，会导致车B无法迅速避让车A，图2是相关技术中车辆交通的示意图。
图3是相关技术中车联网通信的示意图，如图3所示，在车联网通信中，将这种车与网络间的通信称为车对路侧基础设施(Vehicle to Infrastructure，简称为V2I)。V2I通信也称为V2R通信，R就是路边设备(Radio Side Unit，简称为RSU)，V2I和V2R通信就是指Vehicle与网络间的通信，网络可以是：RSU，Infrastructure，eNB(节点B)，中继relay等。
目前的基于3GPP的关于车联网技术的研究，要求在车联网在同一RSU或者某一相近区域范围内，应该通过D2D技术通信快速的交换信息。为了保证终端之间V2V以及终端与RSU之间的V2I/N通信的高时延要求，就要求车联网终端应该实时监听相应的D2D通信资源。
当前3GPP网络中的D2D技术是指LTE SIDELINK direct communication(LTE近场直传通信)，其终端的D2D配置信息主要依赖从系统消息获取，和在申请D2D发送资源时从网络获取。但是随着车联网终端的高速移动，车联网终端在不同小区之间的进行迁移，不同小区中分配的D2D资源不一致。终端需要重新通过系统消息或者其他方式获取D2D监听资源，这就造成了时延。
当前的D2D的接收和发送配置的方法，无法满足车联网在高速运行中在不同小区快速切换的情况下车联网终端V2V/V2I消息的高时效性，无法保证车联网终端V2V或者V2I资源的持续性。针对相关技术中的上述问题，目前尚未存在有效的解决方案。

步骤S402-1：网络侧获取D2D终端上报的第一指示信息，和/或第二指示信息；
步骤S402-2：在第一指示信息用于指示D2D终端需要进行小区的切换，和/或第二指示信息用于指示D2D终端需要更新资源配置信息时，网络侧确定需要向D2D终端发送无线资源链接重配置消息；
步骤S402-3：在第一指示信息用于指示D2D终端不需要进行小区的切换，和/或第二指示信息用于指示D2D终端不需要更新资源配置信息时，网络侧确定不需要向D2D终端发送无线资源链接重配置消息。
由该S402-1至S402-3可知，网络侧确定是否要发送无线资源链接重配置消息的依据是终端上报的第一指示信息和第二指示信息，根据该指示信息的内容确定发送或不发送无线资源链接重配置消息。
在本实施例的另一个可选实施方式中，本实施例的方法还包括：在网络侧确定需要向D2D终端发送无线资源链接重配置消息时，网络侧向D2D终端发送携带有D2D发送资源配置信息的无线资源控制连接重配置消息，其中，D2D资源配置信息用于指示终端进行发送资源的配置。
需要说明的是，D2D资源配置信息包括以下至少之一：D2D发送资源配置信息、D2D接收资源配置信息。基于此，D2D发送资源配置信息包括以下至少之一：D2D发送信息、D2D发现发送信息；D2D接收资源配置信息包括以下至少之一：D2D接收信息、D2D发现发送信息。
也就是说，网络侧发送到终端的D2D接收资源配置信息，可以包括一般通信接收资源信息和/或发现接收资源信息。而在携带终端D2D接收资源配置信息的同时，还可以携带D2D发送资源配置信息。其中，D2D发送资源配置信息，包括一般D2D发送资源信息和或D2D发现发送资源信息。
此外，网络侧在终端需要进行小区切换时发送携带终端D2D接收资源配置信息的RRCConnectionReconfiguration无线资源控制连接重配置消息到终端。而网络侧在终端需要进行小区切换时发送携带终端D2D接收资源信息的RRCConnectionReconfiguration无线资源控制连接重配置消息到终端时，也可以同时携带D2D发送资源信息。
以及，网络侧在发现终端需要更新D2D资源信息时，发送携带终端D2D接收资源配置信息的RRCConnectionReconfiguration无线资源控制连接重配置消息到终端。而网络侧在发现终端需要更新D2D资源信息时，发送携带终端D2D接收资源配置信息的RRCConnectionReconfiguration无线资源控制连接重配置消息到终端时，也可以时携带D2D发送资源信息。
基于上述资源信息，当终端收到携带有D2D接收资源信息的无线资源控制连接重配置消息时，终端根据接收的D2D接收资源信息配置终端的D2D接收。当终端收到携带有D2D发送资源信息的无线资源控制连接重配置消息时，终端根据接收的D2D发送资源信息配置终端的D2D发送。

步骤S504：D2D终端依据D2D接收资源配置信息进行D2D接收资源的配置。
在本实施例的一个可选实施方式中，在设备到设备D2D终端接收车联网的网络侧发送的携带有D2D接收资源配置信息的无线资源控制连接重配置消息之前，方法包括：D2D终端向网络侧上报第一指示信息和/或第二指示信息，其中，第一指示信息用于指示D2D终端需要进行小区的切换，和/或第二指示信息用于指示D2D终端需要更新资源配置信息。
由上述本实施例的方法可知，在终端在状态发生变化时，可以上报指示信息到网络侧，网络侧根据指示信息向终端发送资源配置信息，以及指示终端进行资源的配置，从而使得终端在状态发生转变时进行实时的资源配置，降低了时延。
需要说明的是，在状态信息指示终端需要进行小区的切换，或终端需要更新资源信息时，D2D资源配置信息包括以下至少之一：D2D发送资源配置信息、D2D接收资源配置信息。基于此，D2D发送资源配置信息包括以下至少之一：D2D发送信息、D2D发现发送信息；D2D接收资源配置信息包括以下至少之一：D2D接收信息、D2D发现接收信息。
对于本实施例步骤S506中涉及到的终端依据D2D资源配置信息进行资源的配置的方式，在本实施例的可选实施方式中，可以通过如下方式来实现：

方式二：D2D终端依据D2D接收信息和/或D2D发现接收信息重新配置终端的D2D接收和/或D2D接收发送。
也即是说，在本实施例中当终端收到携带有D2D接收资源信息的无线资源控制连接重配置消息时，终端根据接收的D2D接收资源信息配置终端的D2D接收。当终端收到携带有D2D发送资源信息的无线资源控制连接重配置消息时，终端根据接收的D2D发送资源信息配置终端的D2D发送。
此外，如果终端接收到D2D接收资源信息的无线资源控制连接重配置消息，该D2D接收信息为常规D2D接收资源。终端根据该信息重新配置终端的常规D2D接收。如果终端接收到D2D接收资源信息的无线资源控制连接重配置消息中的，D2D接收信息为D2D发现接收资源。终端根据该信息重新配置终端的D2D发现接收。基于此，如果终端接收到D2D接收资源信息的无线资源控制连接重配置消息中，通信带有常规D2D接收信息和D2D发现接收信息；终端需要根据上述信息重新配置终端的常规D2D接收和D2D发现接收配置。
另外，如果终端接收到D2D发送资源信息的无线资源控制连接重配置消息中的，D2D接收信息为常规D2D发送资源。终端根据该信息重新配置终端的常规D2D发送。，如果终端接收到D2D接收资源信息的无线资源控制连接重配置消息中的，D2D接收信息为D2D发现发送资源。终端根据该信息重新配置终端的D2D发现发送。基于此，如果终端接收到D2D发送资源信息的无线资源控制连接重配置消息中，通信带有常规D2D发送信息和D2D发现发送信息；终端需要根据上述信息重新配置终端的常规D2D发送和D2D发现发送配置。

下面结合本发明的可选实施例对本发明进行举例说明；
为了保证当前车联网终端对于V2V，V2I/V2N通信连续性的要求，本可选实施例提供了一种LTE网络中更新终端D2D通信配置资源的方法，该方法的主要方式可以是：网络侧发送RRCConnectionReconfiguration无线资源控制连接重配置消息到终端，并在其中携带终端D2D接收资源配置信息。需要说明的是，本可选实施例中LTE网络中的D2D技术，是指LTE技术中的sidelink(近场通信)/sidelink direct communication(近场直传通信)。
下面将对本可选实施例的方法进行详细的描述，首先，发送到终端的D2D接收资源配置信息包括：通信接收资源信息和/或发现接收资源信息。此外，携带终端D2D接收资源配置信息的同时，还可以携带D2D发送资源配置信息。其中，D2D发送资源配置信息包括：D2D发送资源信息和/或D2D发现发送资源信息。
可选地，网络侧在终端需要进行小区切换时发送携带终端D2D接收资源配置信息的RRCConnectionReconfiguration无线资源控制连接重配置消息到终端。而网络侧在终端需要进行小区切换时发送携带终端D2D接收资源信息的RRCConnectionReconfiguration无线资源控制连接重配置消息到终端时，也可以同时携带D2D发送资源信息。因此，网络侧在发现终端需要更新D2D资源信息时，发送携带终端D2D接收资源配置信息的RRCConnectionReconfiguration无线资源控制连接重配置消息到终端。
此外，网络侧在发现终端需要更新D2D资源信息时，发送携带终端D2D接收资源配置信息的RRCConnectionReconfiguration无线资源控制连接重配置消息到终端时，也可以携带D2D发送资源信息。而当终端收到携带有D2D接收资源信息的无线资源控制连接重配置消息时，终端根据接收的D2D接收资源信息配置终端的D2D接收。

可选地，如果终端接收到D2D发送资源信息的无线资源控制连接重配置消息中，D2D接收信息为常规D2D发送资源。终端根据该信息重新配置终端的常规D2D发送。而如果终端接 收到D2D接收资源信息的无线资源控制连接重配置消息中的，D2D接收信息为D2D发现发送资源。终端根据该信息重新配置终端的D2D发现发送。基于此，如果终端接收到D2D发送资源信息的无线资源控制连接重配置消息中，通信带有常规D2D发送信息和D2D发现发送信息；终端需要根据上述信息重新配置终端的常规D2D发送和D2D发现发送配置。
本可选实施例还提供了一种在小区切换的情况下更新终端D2D配置的方法，该方法的步骤包括：

步骤S12：终端在接收到该消息后，完成从当前小区到目标小区的切换；更新D2D接收资源配置信息。
其中，终端的D2D接收资源配置信息，包括直传通信接收资源信息或/和直传发现接收资源信息。如果终端在切换前处于D2D通信监听状态，终端在切换后应立即利用新的D2D接收资源配置信息来进行D2D通信监听。而终端在完成D2D通信监听的更新后，发送RRCconnectionReconfigurationComplete消息到网络侧。需要说明的是，本实施例中涉及到的D2D通信监听可以是：直传通信监听和/或直传发现监听。
而在携带终端D2D接收资源配置信息的同时，还可以携带D2D发送资源配置信息，其中，D2D发送资源配置信息包括：一般D2D发送资源信息和或D2D发现发送资源信息。
如果终端在切换前处于D2D通信发送状态，终端在切换后应立即利用新的D2D发送资源配置信息来进行D2D通信发送。而终端在完成D2D通信监听和发送的更新后，发送RRCconnectionReconfigurationComplete消息到网络侧。
本可选实施例还提供了一种网络更新终端D2D配置的方法，该方法的步骤包括：
步骤S21：网络发送RRCconnectionReconfiguration消息到终端并在其中携带终端D2D接收资源配置信息，通知终端更新D2D接收资源配置信息。
步骤S22：终端在接收到该消息后，更新D2D接收资源配置信息。
其中，终端的D2D接收资源配置信息，包括直传通信接收资源信息或/和直传发现接收资源信息。而如果终端在收到重配置消息处于D2D通信监听状态，终端在切换后应立即利用新的D2D接收资源配置信息来进行D2D通信监听。

如果终端在收到重配置消息处于D2D通信发送状态，终端在切换后应立即利用新的D2D发送资源配置信息来进行D2D通信发送。而终端在完成D2D通信监听和发送的更新后，发送RRCconnectionReconfigurationComplete消息到网络侧。

下面结合附图和具体实施例对可选实施例进行详细说明；
实施例一

由上述步骤S802至步骤S810可知，车联网终端A在行驶过程中在小区1中处于连接状态。终端A由于车联网业务而处于D2D直传通信监听状态，接收附近车辆和路边设备通过D2D直传通信发送的V2V信息；在终端A行驶接近小区2的覆盖区域是，小区1根据终端A发送侧测量信息决定终端A需要切换到小区2；通信网络根据终端上报的状态信息，发现终端处于D2D直传通信监听状态。网络发送无线资源控制连接重配置消息到终端A，并在消息中携带D2D直传通信监听配置信息。
终端在接收到网络侧发送的无线资源控制连接重配置消息后，根据重配置消息的配置实现小区1到小区2的切换，并根据其中携带的D2D直传通信监听配置信息，更新终端A的当前D2D直传通信监听配置。

步骤S910：终端发送无线资源连接重配置完成消息到网络侧。
由上述步骤S902至步骤S904可知，车联网终端A在行驶过程中在小区1中处于连接状态。终端A由于车联网V2V业务处于D2D直传通信监听和直传发送状态，接收附近车辆和路边设备基于D2D直传通信发送的V2V信息，同时也在向其他车联网终端或者路边设备发送基于D2D直传通信发送技术的V2V信息。
在终端A行驶接近小区2的覆盖区域时，小区1根据终端A发送侧测量信息决定终端A需要切换到小区2。网络侧根据终端上报的状态信息，发现车终端处于D2D直传通信监听和直传发送状态。
网络侧发送无线资源控制连接重配置消息到终端A，并在消息中携带D2D直传通信接收配置信息和D2D直传通信发送配置信息。终端接收到网络侧发送的无线资源控制连接重配置消息后，根据重配置消息的配置实现小区1到小区2的切换。并根据其中携带的D2D接收和发送配置信息，更新终端A的当前D2D直传通信接收和直传发送配置。
在终端A更新了当前的D2D配置后，终端A可以接收到小区2管理下的其他车联网终端或者路边设备发送的基于D2D的V2V消息。实现了终端在小区和位置切换时，可以实现车联网V2V通信的连续性，保证车联网终端可以在很小的时延下接收到关联区域的车辆和路边设备的信息。同时终端也根据更新后的D2D发送配置信息，发送响应的V2V信息到应该关心该信息的具有小区2配置的D2D接收配置的车联网终端和/或路边设备。
终端在小区切换完成后，发送无线资源连接重配置完成消息到网络。

由上述步骤S1002和步骤S1008可知，车联网终端A在行驶过程中在小区1中处于连接状态。终端A由于车联网V2V业务，处于D2D接收和发送状态，接收附近车辆和路边设备基于D2D发送的V2V信息，同时也在向其他车联网终端或者路边设备发送V2V信息；随着车联网终端在小区内的移动或者/和小区1的网络状况，网络决定终端A需要更新D2D配置。
网络侧发送无线资源控制连接重配置消息到终端A，并在消息中携带D2D直传通信接收配置信息和D2D直传通信发送配置信息。
终端接收到网络侧发送的无线资源控制连接重配置消息后，根据其中携带的D2D接收和发送配置信息，更新终端A的当前D2D接收和发送配置。
