Description

近距离通讯发现方法、装置及系统 技术领域
本发明涉及通信领域，具体而言，涉及一种近距离通讯发现方法、装置及系统。
背景技术
为了保持第三代移动通信系统在通信领域的竞争力，并为用户提供速率更快、时延更低、更加个性化的移动通信服务，同时，为了降低运营商的运营成本，第三代合作伙伴计划(3GPP，3rd Generation Partnership Project)标准工作组正致力于演进分组系统(EPS，Evolved Packet System)的研究。整个EPS包括无线接入网(E-UTRAN，Evolved Universal Terrestrial Radio Access Network)和移动核心网(EPC，Evolved Packet Core Networking)，其中，EPC包含了归属用户服务器(HSS，Home Subscriber Server)、移动性管理实体(MME，Mobility Management Entity)、服务GPRS支持节点(SGSN，Serving GPRS Support Node)、策略计费规则功能(PCRF，Policy and Charging Rule Function)、服务网关(S-GW，Serving Gateway)、分组数据网关(P-GW，PDN Gateway)和分组数据网络(PDN，Packet Data Network)。
当两个用户设备(UE，User Equipment)通过EPS进行通信时，两个UE需要分别与EPS建立承载。但是考虑到UE以及各种移动互联网业务的快速发展，很多业务希望能够发现临近的UE并且进行通信，因此催生了设备到设备(D2D，Device to Device)业务，另外，D2D业务也被称为基于距离的业务(ProSe，Proximity-based Services)。在D2D业务中，当两个UE位置比较接近的时候，可以直接通信，其连接的数据路径可以不绕回到核心网，这样，一方面可以减少数据路由的迂回，另一方面也能够减少网络数据负荷。
目前，常用的D2D业务有D2D发现业务，D2D发现业务的通信架构如图1所示，D2D接入的两个UE只能通过E-UTRAN接入EPC，两个UE可以都属于一个公用陆地移动网络(PLMN，Public Land Mobile Network)或者分属于两个PLMN；对于一个UE，PLMN可以分为归属的PLMN(HPLMN，Home PLMN)和当该UE从其他的PLMN接入时的拜访的PLMN(VPLMN，Visited PLMN)，对于UE当前所处区域的PLMN可以统称为本地的公用陆地移动网络(LPLMN，Local PLMN)，无论该本地的PLMN是HPLMN还是VPLMN。为了实现D2D发现业务，在运营商侧不仅仅部署了EPS，还包括部署D2D发现业务的ProSe应用服务器(ProSe Application Server)，ProSe应 用服务器可以由运营D2D业务的业务提供商提供，也可以由运营EPS的网络运营商提供，在不同PLMN还部署了ProSe功能实体(ProSe Function)。
在D2D发现业务通信架构中，由于UE提供相关的ProSe应用(APP，Application)，其和ProSe应用服务器的接口为PC1接口，提供相关认证功能。UE与UE之间的接口为PC5，用于UE之间的相互直接发现和通信，而UE与ProSe功能实体之间的接口是PC3，用于通过网络的发现认证。ProSe功能实体与现有EPC之间的接口是PC4，包含与P-GW的用户面接口和与HSS的控制面接口，用于D2D发现业务发现认证。ProSe功能实体与ProSe应用服务器的接口为PC2，用于D2D发现业务的应用实现。ProSe功能实体与ProSe功能实体分别有PC6和PC7接口，分别用于UE在漫游和非漫游的两种情况，UE漫游时为PC7接口，UE非漫游时是为PC6接口，这两个接口用于UE进行D2D发现业务时执行两个ProSe功能实体之间的信息交互。
在D2D发现业务中，分为开放的发现业务和限制的发现业务，开放的发现业务即为当一个用户广播发现码时，任何UE都能无限制的接收到这个发现码，并发现该用户。目前开放的发现业务分为三个过程，在本发明中，为了方便描述，UE-A为公布(announce)UE，其对应的归属ProSe功能实体为ProSe Function A，简称PF-A，而UE-B为监控(monitor)UE，其对应的归属ProSe功能实体为ProSe Function B，简称PF-B，因此开放的发现业务分为，被发现UE-A的公布(announce)过程，发现UE-B的监控(monitor)过程，这两个过程都是向对应的归属PF发起发现请求过程，获得无线资源的分配。然后UE-A广播发现码，UE-B接收到发现码后，向PF-A进行匹配，这就是匹配过程。然而对于限制的发现业务，现有技术依然采用上述三个过程，UE-A将随时占用空口资源，广播发现码，寻求UE-B或者其他UE的发现，这将导致无线资源的浪费，不利用限制业务的开展。
针对相关技术中限制的发现业务存在的无线资源浪费的问题，目前尚未提出有效的解决方案。

步骤1402：PF-A发现如果不存在UE-A的用户上下文，则向发送归属寄存器认证请求获取UE-A的用户上下文。如果存在UE-A的用户上下文，则PF-A向应用服务器发送发现认证请求消息，所述消息携带UE-A的业务标识以及UE-A的位置信息，应用服务器认证UE-A后，向PF-A回送发现认证响应消息，所述消息携带UE-A的好友列表，即UE-A的好友对应的业务标识表。
步骤1403：PF-A向UE-A回送发现认证响应消息。
所述步骤1402可以UE-A直接在业务层上与应用层进行认证，则步骤1402先于步骤1401发生，则步骤1401还携带其好友对应的业务标识。
步骤1404：UE-B向其归属的PF-B发送发现请求消息，所述消息携带UE-B标识，所述消息携带发现类型，为限制发现，所述消息还携带本次发现的业务标识，所述消息还表示UE-B期望被好友发现，因此所述消息还可以携带期望被发现的好友或者好友列表，即好友的业务标识列表，所述好友或者好友业务标识的列表至少包含UE-A的业务标识，所述消息还包含UE-B的位置信息。
步骤1405：PF-B发现如果不存在UE-B的用户上下文，则向发送归属寄存器认证请求获取UE-B的用户上下文。如果存在UE-B的用户上下文，则PF-B向应用服务器发送发现认证请求消息，所述消息携带UE-B的业务标识，或者同时包含UE-B期望被UE-A或者其他用户发现的标识，所述消息还携带发现类型为限制的发现业务，所述消息还包含UE-B的位置信息。
步骤1406：应用服务器为UE-B分配发现标识，以及发现标识对应的有效期。所述发现标识由应用服务器标识、和应用服务器为对应UE-B的业务标识分配临时标识组成。应用服务器认证UE-B以及对应的好友列表，UE-B的好友列表至少包含UE-A，且UE-A和UE-B在同一位置区，即UE-B能够发现UE-A。则应用服务器根据UE-A的业务标识向通过PF-A向UE-A发送发现请求认证消息，所述消息携带发现标识，以及发现标识对应的有效期，所述消息还可以携带UE-B的业务标识。
步骤1407：UE-A认证UE-B的业务标识，通过PF-A向应用服务器回送发现请求认可响应消息。
步骤1408：应用服务器向PF-B回送发现认证请求响应消息，所述消息携带发现标识，以及发现标识对应的有效期。
步骤1409：PF-B向UE-B回送发现请求响应消息，所述消息携带发现标识，以及发现标识对应的有效期。
步骤1406、1407与步骤1408、1409并行进行。
步骤1410：UE-A在UE-B对应发现标识有效期中广播或者寻呼发现UE-B，所述广播或者寻呼发现消息携带UE-B的发现标识。
步骤1411：UE-B侦听到广播和寻呼发现后，向UE-A回送寻呼或者广播响应，表示UE-A发现了UE-B，所述广播为UE-B到UE-A的单播消息。
同理，如果步骤1401、1402、1403未执行，则在步骤1406之后可选的执行1401-1403的发现请求认证。
从以上的描述中，可以看出，由网络侧将被发现终端的发现标识分别发送给发现终端和被发现终端，发现终端利用网络侧为被发现终端分配的发现标识进行发现，避免了由于发现终端占用空口资源广播发现码而导致无线资源浪费的问题，节约了无线资源，利用限制发现业务的展开。
显然，本领域的技术人员应该明白，上述的本发明的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明不限制于任何特定的硬件和软件结合。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
