Description

一种设备到设备通信的监听方法及装置、 计算机存储介质 技术领域
本发明涉及无线通信技术领域， 尤其涉及一种设备到设备通信的监听 方法及装置、 计算机存储介质。 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 面社交网络、 近距离数据共享、 本地广告等应用的流行使得人们对了解附 近感兴趣的人或事物并与之通信， 即邻近服务（Proximity Services )的需求 逐渐增加。 传统的基于小区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（D2D， Device-to-Device )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, D2D User Equipment ), 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或直接通信。 D2D 的 应用场景主要有三种：
1 ) UE1和 UE2在蜂窝网络的覆盖下进行通信， 如图 1的模式 1， 用户 面数据不经过网络基础设施；
2 )在弱覆盖区域或无覆盖区域的 UE通过有网络覆盖的 UE中继进行 通信， 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；
3 )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
UE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：
1 ) D2D发现技术是指用于判断或确定两个或多个 D2D用户设备之间 相互邻近（例如在可进行 D2D直接通信范围之内 )或用于判断或确定第一 D2D用户设备邻近第二 D2D用户设备的技术。
2 ) 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。
D2D通信中， 一方面， D2D UE需避免错过可能的需要接收的 D2D通 信数据， 另一方面， 由于 D2D UE接收 D2D SA釆取盲检测的方式， 若需 要监听的 D2D SA接收资源池较大， 将造成大量的 UE电量消耗。 另外， D2D UE监听 D2D SA接收资源池时， 并不能同时进行蜂窝通信或 D2D发 送， 因此 D2D SA的监听时间过长将影响蜂窝通信或 D2D发送。 发明内容
为解决现有存在的技术问题， 本发明实施例主要提供一种设备到设备 通信的监听方法及装置、计算机存储介质，使 D2D UE能够有效的进行 D2D 资源的监听。
本发明实施例的技术方案是这样实现的：
本发明实施例提供的一种设备到设备 D2D通信的监听方法， 该方法包 括：
D2D用户设备（UE )获取 D2D接收资源池信息， 根据所述 D2D接收 资源池信息进行 D2D资源的监听。
本发明实施例提供的一种设备到设备通信数据的监听装置， 该装置包 括： 获取模块、 监听模块； 其中，
获取模块， 配置为获取 D2D接收资源池信息，将获取的 D2D接收资源 池信息发送给监听模块；
监听模块，配置为根据所述 D2D接收资源池信息进行 D2D资源的监听。 本发明实施例还提供一种计算机存储介质， 其中存储有计算机程序， 该计算机程序用于执行上述的设备到设备通信数据的监听方法。
本发明提供了一种设备到设备通信的监听方法及装置、 计算机存储介 质， D2D UE获取 D2D接收资源池信息， 根据所述 D2D接收资源池信息进 行 D2D资源的监听； 如此， 能够使 D2D UE有效的进行 D2D资源的监听， 以实现 D2D UE节电， 并避免错过可能需要接收的 D2D通信数据。 附图说明

图 5 为本发明实施例二提供的设备到设备通信数据的监听方法流程示 意图。 具体实施方式
在有蜂窝网络覆盖的场景下， D2D通信资源通常由基站进行调度分配， 这样可以提高资源复用效率， 同时保证网络侧对 D2D通信的控制以及 D2D 通信与蜂窝通信之间扰协调的效果。 D2D发送资源可以由基站动态调度， 或者基站可为 D2D UE分配半持续调度资源。 有蜂窝网络覆盖下， D2D UE 还可以通过基于竟争的方式获取 D2D发送资源。 公共安全场景下， D2D通 信要求具有很强的鲁棒性， 能够在当前通信资源短缺或者拥塞或者网络基 础设施瘫痪的情况下仍然能够最大限度的提供服务。 因此公共安全要求 D2D通信不仅在有网络覆盖场景下工作， 也要求在部分覆盖以及无网络覆 盖场景下工作。 在无网络覆盖场景下， D2D用户设备可以通过自组织的方 式工作， 并通过竟争方式获取 D2D发送资源。 无网络覆盖下 D2D UE的发 送资源的竟争资源池可以由 UE位于网络覆盖时从 Prose服务器或核心网网 元事先获取， 例如从 Prose功能实体 ( Prose function )或 Prose应用服务器 ( Prose APP server )处菝得。
D2D通信中， 发送方 D2D UE发送 D2D数据之前要先发送 D2D控制 信息，该 D2D控制信息通常称为 D2D调度信息（ SA， scheduling assignment )0 D2D SA中可包含其关联的 D2D数据的资源相关信息，例如， 资源块（RB ) 分配信息、 调制与编码策略（MCS )等。 D2D SA中还包含调度信息 L1接 口标识（ SA LI ID ) (由 Prose ID生成）， 用于在 D2D UE之间的 PC5接口 进行标识，使得接收方 D2D UE可在物理层过滤出其想要接收的 D2D数据。 接收方 D2D UE在进行 D2D通信数据的接收前需获取 D2D接收资源池信 息， 其中包括用于接收的 D2D SA资源池信息。 然后， D2D UE可在用于接 收的 D2D SA资源池上监听 D2D SA,并通过监听到的 D2D SA获取其感兴 趣的 D2D通信数据的资源相关信息，如资源占用情况。在公共安全场景下， 无论接收的 D2D UE是否位于蜂窝网络覆盖下， 都需要接收有网络覆盖下 或无网络覆盖下的 D2D UE发送的 D2D通信数据。 若 D2D UE位于蜂窝网 络覆盖下， 则 D2D接收资源池信息可从服务基站获取； 若 D2D UE位于蜂 窝网络覆盖之外， 则 D2D接收资源池信息由 D2D UE位于网络覆盖时从 Prose服务器或核心网网元事先获取， 例如从 Prose function或 Prose APP server处菝得。
本发明实施例中， D2D UE获取 D2D接收资源池信息， 根据所述 D2D 接收资源池信息进行 D2D资源的监听， 从而， 可以解决 D2D UE如何有效 的进行 D2D资源的监听， 并实现 D2D UE节电和避免错过可能需要接收的 D2D通信数据。
