组通信中组优先级通知方法、设备及系统 技术领域
本发明涉及无线通信技术领域，尤其涉及一种组通信中组优先级通知方法、设备及系统。
背景技术
设备到设备(英文：device to device，缩写：D2D)通信是一种在系统的控制下，允许用户设备之间通过复用小区资源直接进行通信的新型技术；其中，它的一个最重要的应用场景是组通信(group communication)。在组通信中，用户设备(英文：user equipment，缩写：UE)可以和与该UE处于同一群组内的其他多个UE通过一对多(one-to-many)的D2D通信方式进行数据传输。
在实际应用中，当UE在一群组内进行组通信之前，需要基站(英文：base station，缩写：BS)根据所述群组的组优先级，为UE事先分配用于组通信的相应资源(如时频资源)。但是，由于基站自身事先并未存储有群组的组优先级，因此，如何使基站获得群组的组优先级成为组通信中的关键问题。

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。
图1示出了本发明实施例提供的组通信中组优先级通知方法的应用场景，该应用场景可以包括：多个通信群组、基站、演进的分组核心(英文：evolved packet core，缩写：EPC)网络设备以及应用服务器；其中，在该应用场景中，一个基站可以覆盖多个通信群组，即一个基站可以为多个群组同时调度通信资源；每个通信群组可以包含多个用户设备UE，所述UE可以为蜂窝式电话、寻呼器、个人数字助理(英文：personal digital assistant，缩写：PDA)、膝上型计算机、或其它支持即时即通(英文：push to talk，缩写：PTT)通信的手持式、静止或便携式通信设备；EPC网络设备可以为近距离业务功能实体(英文：proximity service function，缩写：ProSe Fuction)，可以为归属签约服务器(英文：home subscriber server，缩写：HSS)，还可以为策略与计费规则功能单元(英文：policy and changing rules function，缩写：PCRF)；应用服务器可以为某个行业或某个部门内部使用的、用于在组通信过程中确定组优先级的设备；优选的，该应用服务器可以处于关键任务对讲通信(英文：mission critical push to talk，缩写：MCPTT)系统(如公安部门、消防部门)中。
需要说明的是，图1所示应用场景中的EPC网络设备在接收到应用服务器发送的群组的组优先级后，并不是直接将组优先级通知给基站，而是将组优先级通过其他一些设备(此部分未在附图1中示出)发送至基站；例如，如图1A所示，EPC设备为ProSe Fuction时，ProSe Fuction通过HSS和移动性管理实体(英文：moblity management entity，缩写：MME)；或者UE将组优先级通知给基站； 如图1B所示，EPC网络设备为HSS时，HSS通过MME将组优先级通知给基站；如图1C所示，EPC网络设备为PCRF时，PCRF通过分组数据网络网关(英文：packet data network gateway，缩写：PGW)和MME将组优先级通知给基站。
下面通过实施例一、实施例二、实施例三、实施例四分别对各设备执行本发明提供的组通信中组优先级通知方法进行介绍。
实施例一
如图2示出了本发明实施例提供的一种组通信中组优先级的通信方法的流程图，应用于ProSe Fuction，所述方法可以包括：
201、ProSe Function接收应用服务器发送的第一消息；所述第一消息包含：用户设备的第一用户标识、所述用户设备所处群组的第一组标识以及所述群组的组优先级。
其中，所述第一用户标识用于标识所述用户设备，可以为：第三代合作伙伴计划(英文：3rd generation partnership project，缩写：3GPP)定义的一种外部标识，如：移动用户号码(英文：Mobile Subscriber International ISDN/PSTN number，缩写：MSISDN)，ISDN为综合业务数字网，是integrated service digital network的简称，PSTN为公共交换电话网络，是public switched telephone network的简称。
所述群组可以为用户设备签约的多个群组中的任一群组；所述用户设备可以为所述群组中组通信的发起者；第一组标识可以为应用层组标识，用于标识所述群组在行业或部门中的小组名称；例如，一消防部门中的某一用户同时签约有群组1(紧急小组)，群组2(领导小组)，群组3(服务小组)等，则当该群组为服务小组时，第一组标识为消防部门-群组3。
所述组优先级可以为所述应用服务器根据所述群组的当前属性、与所述当前属性对应的属性值以及预设的优先级等级划分关系动态确定的，用于表示所述群组在通信系统中的级别，以保证确定出的组优先级符合群组通信的需求；通常情况下，组优先级可以分为高、中、低三级。
其中，所述当前属性包含静态属性和/或动态属性；所述静态属性为所述群组自身固有的属性，不会随着群组的变化而变化，包含但不限于所述群组的类型、所述群组的运行时间、所述群组的默认最小优先级中的一种或多种；
所述动态属性为随着群组内所发生的事情的变化而变化的属性，包含但不限于所述群组内发生的事件类型、所述事件的严重性中的一种或多种。
优选的，ProSe Function可以通过PC2接口接收应用服务器发送的第一消息。
202、ProSe Function根据接收到的所述第一消息，向基站发送通知消息；所述通知消息包含：所述用户设备的第二用户标识、所述群组的第二组标识以及所述群组的组优先级。
其中，所述第二用户标识也用于标识所述用户设备，可以为3GPP系统定义的一种内部标识，如：国际移动用户识别码(英文：international mobile subscriber identification number，缩写：IMSI)。
所述第二组标识可以为网络层组地址，如：层2(Layer 2)地址，用于标识用户设备进行组通信的目的地址。优选的，所述ProSe Function可以在步骤202之前，根据所述第一组标识，从ProSe Function内部存储的组地址中选择任一组地址作为所述群组的第二组标识，并建立所述第二组标识和所述群组的组优先级之间的对应关系。
示例性的，本实施例中，所述ProSe Function向基站发送通知消息可以包括：
所述ProSe Function先通过PC4a接口向归属签约服务器(英文：home subscriber server，缩写：HSS)发送所述通知消息，所述HSS通过S6a接口向MME发送所述通知消息，再由所述MME通过S1接口向所述基站发送所述通知消息；
或者，所述ProSe Function先通过PCx接口向MME发送所述通知消息，再由所述MME通过S1接口向所述基站发送所述通知消 息。
需要说明的是，HSS向MME转发的通知消息、以及MME向基站转发的通知消息中可以增加除所述用户设备的第二用户标识、所述群组的第二组标识以及所述群组的组优先级之外的其他一些信息，本发明实施例对此不进行限定，但在转发过程中，该通知消息必须要包含所述群组的组优先级，以保证基站能够接收到群组的组优先级。
具体的，本发明实施例中，所述ProSe Function可以被动地直接接收应用服务器发送的第一消息，但作为一种更通用的实现方式，在步骤201之前，所述ProSe Function也可以先向应用服务器发送用于指示应用服务器向ProSe Function发送组优先级的消息后，再接收应用服务器发送的第一消息，具体实现如下：
所述ProSe Function接收所述用户设备发送的第二消息；所述第二消息包含：所述用户设备的第二用户标识、所述群组的第一组标识以及应用标识；
所述ProSe Function根据所述应用标识，向所述应用服务器发送第三消息，所述应用服务器在确定所述群组的组优先级后，向所述ProSe Function发送所述第一消息；所述第三消息包含所述用户设备的第一用户标识、所述群组的第一组标识。
其中，所述应用标识用于标识所述应用服务器。
优选的，本发明实施例中，所述ProSe Function接收到的第二消息，及向应用服务器发送的所述第三消息中还可以包括：所述群组的当前属性及与所述当前属性对应的属性值，以便于应用服务器根据所述群组的当前属性及所述当前属性对应的属性值，确定所述群组的组优先级。
此外，在ProSe Function接收到所述用户设备发送的第二消息后，所述方法还包括：所述ProSe Function与HSS之间认证所述用户设备的合法性、及对所述用户设备发起的组通信进行授权检查。
进一步的，本发明实施例中，所述方法还可以包括：
所述ProSe Function向所述应用服务器发送所述群组的第二组标识，以便于应用服务器根据所述第二标识，建立所述第二标识与所述群组的组优先级的对应关系，并将该对应关系直接通过用户设备向基站发送。
进一步的，本发明实施例中，所述ProSe Function除通过HSS、MME等设备向基站发送包含组优先级的通知消息之外，作为一种更通用的方法，所述ProSe Function还可以通过用户设备向基站发送包含组优先级的消息，具体实现如下：
所述ProSe Function在接收到应用服务器发送的第一消息之后，向所述用户设备发送第四消息，所述用户设备向基站发送包含所述群组的第二标识和所述群组的组优先级的消息；其中，所述第四消息包含所述第二组标识和所述群组的组优先级。
由上可知，本发明实施例提供一种组通信中组优先级通知方法，当ProSe Function接收到应用服务器发送的包含：用户设备的第一用户标识、所述用户设备所处群组的第一组标识以及所述群组的组优先级的第一消息后，根据接收到的所述第一消息，向基站发送包含：所述用户设备的第二用户标识、所述群组的第二组标识以及所述群组的组优先级的通知消息，以使得基站根据组优先级为组通信分配相应的通信资源。如此，通过ProSe Function将群组的组优先级通知给基站，解决了组通信中如何将群组的组优先级通知给基站的问题，为用户设备进行组通信打下基础；并且，由于该组优先级是应用服务器根据群组的当前属性动态确定的，使得基站可以根据该群组优先级为群组分配能够满足群组当前通信需求的通信资源。
实施例二
如图3示出了本发明实施例提供的一种组通信中组优先级的通信方法的流程图，应用于应用服务器，所述方法可以包括：
301、应用服务器确定用户设备所处群组的组优先级。
其中，所述组优先级用于表示所述群组在通信系统中的级别；可以分为高、中、低三级；可实现的，本发明实施例中，应用服务 器在向ProSe Function发送第一消息之前，可以由应用服务器根据所述群组的当前属性、与所述当前属性对应的属性值以及预设的优先级等级划分关系确定所述群组的组优先级。
其中，所述当前属性包含静态属性和/或动态属性；所述静态属性为所述群组自身固有的属性，不会随着群组内事件的变化而变化，包含但不限于所述群组的类型、所述群组的运行时间、所述群组的默认最小优先级中的一种或多种；所述动态属性为随着群组内所发生的事情的变化而变化的属性，包含但不限于所述群组内发生的事件类型、所述事件的严重性中的一种或多种。
需要说明的是，在实际的组通信过程中，应用服务器在初次确定群组的优先级时，会根据群组的静态属性进行确定，而后，则会根据群组的动态属性不断更新群组的优先级，以使得群组的组优先级与群组的动态属性相符合，保证基站根据群组的当前优先级为用户设备的群组分配合理的通信资源。
例如，下表1存储有应用服务器所在部门内各群组、各群组的组标识以及各群组的静态属性的对应关系；表2为预设的优先级等级划分关系表，则可知群组1的组优先级为中优先级；此时，若群组1内的用户设备接收到火灾报警，且事件比较严重等动态属性，则应用服务器更新群组1的组优先级为高优先级。

进一步的，本发明实施例中，除通过步骤302向ProSe Function发送第一消息，以使得ProSe Function向基站发送包含组优先级的通知消息之外，作为一种更通用的方式，还可以通过用户设备向基站发送包含组优先级的消息，具体实现如下：
所述应用服务器向所述用户设备发送第三消息；其中，所述第三消息包含所述群组的第二组标识和所述群组的组优先级。
其中，所述第二组标识可以为网络层组地址，如：层2(Layer2)地址，用于标识用户设备进行组通信的目的地址。
优选的，应用服务器可以根据所述第一组标识，从所述应用服务器内部存储的组地址中选择任一组地址作为所述群组的第二组标识，并建立所述第二组标识和所述群组的组优先级之间的对应关系；

进一步的，本发明实施例中，应用服务器还可以向HSS或者PCRF发送所述第一消息，HSS或者PCRF向基站发送包含组优先级的消息。
由上可知，本发明实施例提供一种组通信中组优先级通知方法，由应用服务器向ProSe Function发送包含：用户设备的第一用户标识、所述用户设备所处群组的第一组标识以及所述群组的组优先级的第一消息，以使得ProSe Function将群组的组优先级通知给基站，解决了组通信中如何将群组的组优先级通知给基站的问题，为用户设备进行组通信打下基础；并且，由于该组优先级是应用服务器根据群组的当前属性动态确定的，使得基站可以根据该群组优先级为群组分配能够满足群组当前通信需求的通信资源。
