Description

集群用户服务器和终端以及区域受限业务的处理方法 技术领域
本发明涉及集群通讯技术领域，特别是涉及一种基于GCSE(Group Communication System Enabler，群组通信系统推动器)框架的MCPTT(Mission Critical Push To Talk，关键任务一键通)集群语音业务标准的集群用户服务器和终端以及区域受限业务的处理方法。
背景技术
集群移动通信系统是一种专用业务调度系统，系统中多个用户(部门、群体)共用一组无线电信道，并动态地使用这些信道的专用移动通信系统，主要用于指挥调度通信。集群通讯系统具有共享资源、分担费用、共用信道设备及服务的多用途、高效能等特点。
集群移动通讯系统的业务应用需要根据业务类型为集群用户设定业务范围，该类业务范围可称之为区域限定业务。例如在现有铁路的GSM-R(Global System for Mobile Communications-Railway，铁路的全球移动通信系统)系统中的VGCS(Voice Group Call Service，语音组呼业务)业务与VBS(Voice Broadcast Service，语音广播业务)业务。这类业务在发起、建立、释放时需要在限定的区域中进行。业务进行时，组内用户如果离开限定区域，业务将发生中断。在GSM-R系统中，区域限定业务与GSM网络合设，需要专用GSM网络、专用手机以及特制SIM(Subscriber Identity Module，客户识别模块)卡之间相互协同完成区域限定业务。
随着通讯技术的不断发展以及用户需求的不断增加，组通信/集群通信已从传统的专网应用逐渐向公网应用转变，在此背景下，3GPP(3rd Generation Partnership Project，第三代合作伙伴计划)在LTE(Long Term Evolvement，长期演进)技术之上提出了应用于组通信/集群通信标准框架GCSE。制订了MCPTT集群语音业务标准和eMBMS(enhaused Multimedia Boardcast Multicast Service，增强型多媒体广播多播业务)规范。MCPTT规 范了LTE网络中PTT(Push To Talk，一键通)业务的实现标准，在应用层设计呼叫控制过程，实现完善的语音集群功能。
伴随着通讯技术的演进的，各集群行业运营商为了进一步提高运营效率、改善服务质量，提出的行业集群通信业务需求与日俱增。如应用于铁路中GSM-R系统，其数据业务能力、带宽及频段干扰越来越难以满足行业通讯发展的要求。另一方面，随着LTE的快速发展，GSM-R市场规模不断萎缩。预测GSM-R预计将于2020年开始走向衰落。各行业集群通信面临着迫切的产业升级换代的要求，基于LTE承载网下的集群通讯技术已成大势所趋，移动通信产业正处于快速发展中。
现有的GCSE框架如图1所示，GCSE Application(GCSE应用)与GCSE AS(GCSE Application Server，GCSE应用服务器)通过C/S(Client/Server，客户机/服务器)模式进行交互，实现了业务应用与承载网络的分离，使业务更加充分地利用eMBMS技术的高带宽、低时延、低成本的特点，给用户提供高品质、多样性、大容量的集群业务体验，同时这样的交互模式也使用户的管理与维护更加灵活高效。
发明人在实现本发明时发现，在实际的集群业务应用中，仍然存在业务区域受限的业务需求，例如铁路上用于行车指挥的调度部门，如编组场、调度车站。集群用户组需要在业务区域内处理大量的调车作业，其业务区域较为集中，而组内不在业务区域内的集群用户无需参与业务。根据目前3GPP组织提出的MCPTT业务定义时，没有对区域受限业务的给出明确定义系统方案与通讯方法。

本发明实施例通过在MCPTT服务器预先设定受限区域、集群用户实时上报ECGI位置信息、GCSE AS维护业务区域内、业务区域外的组成员实例的方式，完成了集群区域业务的管理，满足了在MCPTT业务中对区域受限业务的需求。本发明定义了基于GCSE框架的受限区域业务的系统与系统管理方法，基于数据、语音以及多媒体的集群业务均可使用该组区域的设定方法，集群应用与LTE承载网络分离，架构更加合理。本发明填补了3GPP标准中MCPTT受限区域业务的空白，满足了业务严格受限集群用户的需求。另外，本发明的受限区域业务的定义放在应用层，与空口技术单播、多播技术无关；本发明中区域内人员的过滤管理与组成员中采用何种方式建立业务做到最低耦合，受限区域设定时可包含支持多播方案的区域，也可包含支持单播方案的区域，区域的单位为LTE网络的ECGI作为位置单位，兼容了大势所趋的多播技术方案的实现。再有，本发明的受限区域业务系统可融合到现有协议中的MCPTT业务架构，系统中区域管理与业务流程分离，模块设计合理，符合低耦合高内聚的设计思想，不影响3GPP协议的演进。

具体实施方式
为了解决现有技术不能满足在MCPTT业务中对区域受限业务的需求的问题，本发明提供了一种集群用户服务器和终端以及区域受限业务的处理方法，以下结合附图以及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不限定本发明。
本发明提供一种基于GCSE框架的MCPTT区域限定业务的通讯系统，包括基于MCPTT Client的区域限定业务集群用户终端与集群用户服务器。其中，MCPTT定义了LTE网络下PTT业务的实现标准，在应用层设计呼叫控制过程，实现完善的语音集群功能。而PTT又称“一键通”，是一种移动电话服务，源于集群通信技术。PTT实现了步话机的移动语音业务，具有呼叫建立时间短，讲话才占用信道，接听只监听信道，接收方无需摘机即可随时接收呼叫信息。MCPTT Server为GCSE AS的一个实例，用以集中化管理MCPTT关键业务功能，例如，集群用户组管理、组播广播业务管理、发言权控制、紧急呼叫管理、私密呼叫管理等业务。实际部署时， MCPTT Server可以集中部署，也可以分布式部署，采用MCPTT Server伙伴管理的形式，由2个或者2个以上的MCPTT Server组成，其中一个MCPTT Server作为主系统，其它系统均作为伙伴系统，用户的管理信息均存储在主系统中，包含用户配置、用户业务权限等。下面对该通讯系统及通讯方法进行详细描述：
实施例1
本发明实施例的一种集群用户服务器如图2所示，包括MCPTT服务器和群组管理服务器。所述MCPTT服务器包括位置信息获取单元、区域业务管理单元和融合互通网关单元，所述群组管理服务器包括受限区域设置单元、位置信息分析单元和群组管理单元。
位置信息获取单元设置为接收集群用户终端的用户标识信息与用户位置信息，所述用户位置信息为用户上报的ECGI。
区域业务管理单元设置为处理业务的发起、业务上下文的建立、用户业务的加入和用户业务的释放。业务建立时刻，区域业务管理单元向位置信息分析单元请求区域内用户列表与此用户列表当前驻留的位置信息列表，向该用户一一发送业务建立流程；业务进行时，根据位置信息分析单元上报的用户位置信息更新通知，加入用户或者释放用户业务，该通知携带加入/释放的用户标识列表与该用户列表所属位置信息列表。
融合互通网关单元设置为完成多个MCPTT服务器之间的控制面消息传送；
受限区域设置单元设置为以集群用户组为单位预先设定并存储受限区域；受限业务区域包括ECGI列表、受限区域中存储区域与用户组的关联关系。
位置信息分析单元设置为以集群用户组为单位，根据预设受限区域与集群用户终端提供的位置信息(即ECGI)，判定用户的位置信息与受限区域的关系；位置信息分析单元维护区域内用户列表、区域外用户列表以及位置信息变化用户列表；业务进行时，根据用户位置更新时，通知区域业 务管理单元，及时通知用户参与集群业务或者退出集群业务。
群组管理单元设置为以集群用户组为单位设置集群用户组内签约的用户。
实施例2
本发明实施例的一种集群用户终端如图3所示，包括位置信息上报单元和区域业务处理单元。
位置信息上报单元设置为向集群用户服务器上报用户标识与用户位置信息，所述用户位置信息为当前驻留的LTE网络中ECGI；上报方式可以为实时上报，也可以周期上报。
区域业务处理单元与MCPTT服务器配合完成MCPTT业务流程控制。用于MPCTT业务的发起、离开、结束和一键通抢占等控制面流程控制，并处理来自集群用户服务器的业务控制消息下发的业务接入通知、业务建立通知和业务中断通知。
实施例3
当采用图2所示的集群用户服务器时，本发明实施例的一种区域受限业务的服务器端处理方法如图4所示，包括以下步骤：
步骤s401，以集群用户组为单位预先设定并存储受限区域。本实施例中，业务提供商授权部分业务管理用户预先在MCPTT Server中设定受限区域，存储到受限区域设置单元中，受限区域由若干ECGI列表组成，并存储与用户组的映射关系。另外，在预先设定受限区域时，对组内权限高的成员设定区域不受限。
步骤s402，接收集群用户终端发送的业务发起消息，所述消息携带ECGI信息、用户标识、组标识和业务标识。本实施例中，在接收到该消息后，还需完成用户信息与组信息校验。
步骤s403，判断所述用户终端是否是在受限区域内发起的业务；如果是，则转步骤s404，否则通知用户业务区域受限，业务建立失败。本实施 例中，可以采用两种方式判断用户终端是否是在受限区域内发起的业务。一种方式是获取区域内用户列表，判定所述用户终端是否在区域内列表内；具体为：查询位置信息分析单元，获取区域内用户列表，判定发起用户是否在区域内列表内。另一种方式首先根据所述组标识获取对应集群组的受限区域，然后比较所述用户终端的ECGI信息与所述受限区域的关系；具体为：区域业务管理单元根据其携带的字段，与受限区域设置单元交互，获取用户组对应的受限区域，判定用户携带的ECGI信息与受限区域的关系。
步骤s404，根据业务类型建立业务上下文。本实施例中，根据业务类型建立业务上下文包括分配呼叫标识、为发起用户分配IP地址与端口。
步骤s405，通知所述受限区域内的组内用户终端加入所述业务。本实施例中，MCPTT Server区域业务管理单元向位置信息分析单元请求区域内用户列表及其用户位置信息列表，通知区域内的组内用户加入业务。
本实施例中，在所述通知受限区域内的组内用户终端加入所述业务之后，还包括实时接收用户上报的位置信息，当用户位置信息变化时，及时进行用户业务的加入或用户业务的释放。具体包括：
业务进行时，MCPTT Server位置信息获取单元实时接收用户上报的位置信息即ECGI信息，位置信息分析单元实时维护集群用户实例的位置信息；用户位置信息变化时，需及时向位置信息获取单元上报，便于MCPTT Server区域业务管理单元维护用户业务，及时通知用户加入或者退出集群业务。
业务进行时，MCPTT Server区域业务管理单元接收到来自位置信息分析单元的用户位置区域更新通知时，向更新到受限区域内的用户下发业务接入消息，包括：
(1)业务进行时，当组内用户从受限区域外移动到受限区域内时，位置信息分析单元向区域业务管理单元发送位置更新至区域内通知，区域业务管理单元通知该用户加入业务；
(2)业务进行时，组内用户执行终端开机，首次进入网络，位置信息分析单元向区域业务管理单元发送位置更新至区域内通知，MCPTT Server业务管理单元通知该用户加入业务。
同时，业务进行时，组内用户释放/拒绝业务后，MCPTT Server区域业务管理单元周期通知用户加入网络。
另外，业务进行时，组内用户出受限区域时，位置信息分析单元向区域业务管理单元发送位置更新至区域外通知，MCPTT Server业务管理单元需结束用户的业务，必要时，结束整个区域受限业务。
本实施例中，所述方法还包括跨MCPTT Server管理区域限定业务的通讯方法：当多个关键任务一键通MCPTT服务器管理的集群组重组时，MCPTT服务器接收其归属用户上报的位置信息，并管理各自的集群组的区域受限业务。具体为：MCPTT支持用户组之间的重组操作，该操作允许将两个用户组临时合并为一个组，如此以来，就可能存在跨MCPTT Server管理区域限定业务时。此时的管理方式为，用户向归属的MCPTT Server上报位置信息，各自的MCPTT Server管理签约组的区域限定业务。当临时组业务发起时，通过融合互通网关传递业务请求，各自的MCPTT Server建立业务上下文信息，各自的MCPTT Server管理自身签约组的用户区域限定业务。
本实施例还包括业务空闲状态的通讯方法，具体包括：
MCPTT Server位置信息获取单元接收用户发送的ECGI，位置信息分析单元与群组管理单元交互获取用户所属用户组标识，再与受限区域设置单元交互，获取该用户组标识对应的受限区域。从而，位置信息分析单元通过与所配置的受限区域对比，判定用户是否在受限区域内。通过此手段，位置信息分析单元针对每一个用户组，维护三张列表，即区域内用户列表、区域外用户列表、位置信息更新用户列表。
实施例4
当采用图3所示的集群用户终端时，本发明实施例的一种区域受限业 务的用户终端处理方法如图5所示，包括以下步骤：
步骤s501，向集群用户服务器上报用户标识与用户位置信息，所述用户位置信息为ECGI。本实施例中，向集群用户服务器上报用户标识与用户位置信息的过程包括：在登录或退出对应的GCSE应用或位置发生变化时，主动向集群用户服务器发送用户标识与用户位置信息；或周期向集群用户服务器上报用户标识与用户位置信息；或在集群用户服务器主动查询组内各个组成员所在的位置信息，并根据组标识判定属于所述组时，将用户标识与用户位置信息返回所述集群用户服务器。本实施例中用户在业务发起时，由区域业务处理单元向MCPTT Server请求业务，消息携带当前驻留LTE小区的ECGI信息、用户标识、组标识以及业务标识。
步骤s502，根据集群用户服务器下发的业务接入通知，加入所述业务。
本实施例还包括业务空闲状态的通讯方法，具体包括：位置信息上报单元向归属MCPTT Server上报当前驻留的LTE小区ECGI信息；在用户终端小区切换或者重选时，位置信息上报单元实时上报自身驻留的目标ECGI信息与用户标识信息，结合周期传送方式，向MCPTT Server周期上报。
实施例5
本实施例为集中部署的MCPTT Server的区域限定业务的通信方法，包括以下步骤：
步骤一、授权用户预先在针对集群用户组设定受限区域，存储到受限区域设置单元中，受限区域由若干ECGI组成的列表，并存储受限区域与用户组的关联关系。本实施例中，区域受限业务受限区域设置流程如图6所示，由授权用户通过网管软件在GCSE AS中根据该集群用户对应的工作区域设置受限区域。例如，对铁路车站所管辖范围，边场站中工作人员调车作业的工作区域等。这些区域在LTE网络中，部署为若干ECGI的列表，列表中至少存在一个ECGI。
步骤二、用户向MCPTT Server上报自身的用户位置信息。用户终端 承载用户的信息，通过用户终端实时、周期向MCPTT Server上报自身的ECGI；
具体来说，用户终端向MCPTT Server上报位置信息有几种方式：
1)主动上报式：即当集群用户终端在登录或退出其对应的GCSE Application时，或者该集群用户终端的位置发生变化时，主动向GCSE AS发送其用户标识信息，以便GCSE AS获取与分析用户的位置信息；当处于连接状态的集群用户进行小区切换；或处于空闲状态的集群用户进行TAU(Tracking Area Update，跟踪区更新)，或处于空闲状态的集群用户进行TAC(Tracking Area Code，跟踪区重选)等。集群用户终端向GCSE AS发送用户标识信息时，通过协议中定义的GC1接口，即SIP(Session Initiation Protocol，会话初始协议)消息，经过LTE承载网络透明传送至MCPTT Server。
2)周期上报式：通过MCPTT Client周期向MCPTT Server上报该集群用户终端的ECGI信息。周期上报时携带用户的标识、组标识以及ECGI信息。
3)被动查询时：MCPTT Server主动查询组内各个组成员所在的位置信息，携带组标识，组成员接收到后，判定自身位于这个组，将自身的ECGI信息与用户标识返回MCPTT Server。
步骤三、MCPTT Server接收到用户所在的ECGI后，与所配置的受限区域ECGI列表对比，判定用户所在终端是否属于受限区域。
具体来说，位置信息获取单元获取到用户的位置信息后，将用户标识、位置信息传送到位置信息分析单元，位置信息分析根据用户标识获取用户所属的组标识，再根据组标识获取对应集群组的受限区域，然后比较用户的ECGI信息与受限区域的关系，其中位置信息的上报与分析流程如图7所示。进一步地，维护区域内用户列表及其用户ECGI列表、区域外用户列表以及区域信息更新用户列表。MCPTT Server接收一次来自用户位置上报信息，则触发更新一次区域内用户列表及其用户ECGI列表、区域外 用户列表以及区域信息更新用户列表。
为了防止同一用户频繁更新位置信息，MCPTT Server可设置保护定时器X，定时时长为Y，用户第一次上报位置信息后，在时长Y内再没有收到该用户的位置信息，则更新一次区域内用户列表及其用户ECGI列表、区域外用户列表以及位置信息更新用户列表。
步骤四、集群用户向MCPTT Server请求业务时，携带当前驻留LTE小区的ECGI信息、用户标识、组标识、业务标识等业务属性信息；
具体的，所属用户在发起集群业务时，通过MCPTT Client中的位置信息上报单元读取终端所驻留的LTE小区的ECGI信息。也可以采用回调的形式，当驻留的ECGI发生变化时LTE网络通知MCPTT Client位置信息上报单元。位置信息上报单元将对应的LTE的ECGI信息发给MCPTT Server。
步骤五、MCPTT Server区域业务管理单元接收到用户标识与ECGI后，判定用户是否在受限区域内。
本发明实施例的区域限定业务建立流程如图8所示，具体来说，根据用户发起业务时携带的组标识，在受限区域业务单元中查找用户组关联的受限区域，比较用户发起的位置信息是否所属受限区域，属于受限区域，则根据业务类型建立业务上下文(分配呼叫标识、为发起用户分配IP与端口)；否则，通知用户业务区域受限，业务建立失败；进一步的，区域业务管理单元向位置信息分析单元请求区域内用户标识及其用户所在的当前ECGI信息列表，以便通知区域内的组内用户加入业务；
步骤六、业务进行时，MCPTT Server位置信息获取单元仍需要实时接收用户上报的位置信息，位置信息分析单元实时维护集群用户实例的位置信息；业务进行时，用户位置信息变化时，仍需及时向位置信息获取单元上报，便于MCPTT Server区域业务管理单元维护用户业务，及时通知用户参与集群业务或者退出集群业务。
具体来说，业务进行时，MCPTT Server区域业务管理单元接收到来 自位置信息分析单元的用户位置区域更新通知时，向更新到受限区域内的用户下发业务接入消息，本发明实施例的区域限定业务过程管理流程如图9所示，具体包括：
1)业务进行时，当组内用户从受限区域外移动到受限区域内时，位置信息分析单元向区域业务管理单元发送位置更新至区域内通知，区域业务管理单元通知该用户加入业务；
2)当业务进行时，组内用户执行终端开机，首次进入网络，位置信息分析单元向区域业务管理单元发送位置更新至区域内通知，MCPTT Server业务管理单元通知该用户加入业务；
MCPTT Server区域业务管理单元根据用户的数量与网络的配置，采用单播技术或者多播技术向受限区域内用户发起业务建立流程。单播技术下，LTE承载网为每一个用户分配特定的频率，MCPTT Server受限区域内组内用户一一发送业务建立流程，携带业务标识、呼叫类型、组标识；多播情况下，多播区域内的组内用户共同在广播信道上接收通知，统一在公共信道上接收业务。
步骤七，业务进行时，组内用户释放/拒绝业务后，MCPTT Server区域业务管理单元周期通知用户加入网络；
步骤八、业务进行时，组内用户出受限区域时，位置信息分析单元向区域业务管理单元发送位置更新至区域外通知，携带出组呼区域的用户标识，MCPTT Server业务管理单元需结束用户的业务，必要时，结束整个区域受限业务。
实施例6
本实施例为分布式部署的MCTT Server的区域限定业务的通讯方法，本发明实施例的跨MCPTT Server的区域业务建立流程如图10所示，包括以下步骤：
这里我们假设用户1、用户2、用户3签约到MCPTT Server1，签约到Group1，并设置受限区域为Area1；用户4、用户5、用户6签约到MCPTT  Server2，签约到Group2，受限区域为Area2。
授权用户将MCPTT Server1将Group1与Group2合并为一个临时组Group3，根据3GPP协议，MCPTT Server1与MCPTT Server均存储临时组信息，包含临时组号Group3以及组优先级等信息。应当可以理解的，这里使用用户X来区分不用的用户，GROUPX用来区分集群组，采用这些术语来区分用户与组内用户个数，但用户、个数、组标识不应限于这些术语。
Area1为用户业务受限区域，通过网管后台配置完成后，存储为若干ECGI的列表，并关联Group1。
同样的，Area2为用户业务受限区域，通过网管后台配置完成后，存储为若干ECGI的列表，并关联Group2。
集群用户1、用户2、用户3位置更新时，将自身的ECGI信息以及用户标识上报给归属MCPTT Server，MCPTT Server位置信息获取单元接收到这些用户的位置信息后，转交给位置信息分析单元处理。首先通过群组管理单元解析临时组号，得到用户所属的组标识，即Group1，再根据Group1获取预先设置的受限区域Area1，分析每一个用户的位置信息ECGI是否属于Area1。因此，可以得到区域内用户列表及其当前位置区域，以及区域外用户列表，位置信息更新用户列表。
当用户1在受限区域外发起业务时，携带当前驻留的LTE的ECGI信息以及临时组号Group3，MCPTT Server1区域业务管理单元接收到用户信息与临时组号后，解析临时组Group3标识，查找到该用户归属于自身的用户组Group1，通过组标识获取自身配置的受限区域Area1，发现用户1的ECGI不在区域Area中，MCPTT Server业务区域管理单元提示用户1区域业务发起失败。
当用户1位置移动到Area1内时，用户的位置信息实时更新到MCPTT Server的区域分析单元，该单元维护区域内用户列表及其当前位置信息、区域外用户列表。此时，用户1发起临时组业务，携带用户标识、临时组 标识Group3以及当前的位置信息ECGI，MCPTT Server业务区域管理单元发现用户在所属区域内，对用户及临时组鉴权，通过融合互通网关传递业务建立请求，携带临时组标识Group3。MCPTT Server2区域业务管理单元解析临时组号Group3，并解析归属于自身MCPTT Server的用户组，即Group2，区域业务管理单元再从位置信息分析单元获取对应区域内用户成员，携带Group2，获取完成后，对组内成员一一鉴权后，下发业务建立通知。
于此同时，MCPTT Server1进行同样的工作，分解临时组Group3标识，得到归属于自身的用户组Group1；通过Group1从位置信息获取单元获取Area1内组内成员，对组内成员一一鉴权后，下发业务建立通知。
MCPTT Server1与MCPTT Server2中的位置信息单元实时获取用户位置信息，位置信息分析单元根据用户上报的位置信息与其限定区域分析区域内用户列表及其当前位置信息、区域外用户列表、位置信息更新用户列表。当用户的位置信息从区域内更新到区域外时，或者从区域外更新到区域内时，均需要通知区域业务管理单元通知用户释放业务或者重新建立业务。业务进行时，包括的位置信息变化包括：
1)组内用户从受限区域外移动到受限区域内时，用户归属MCPTT Server中位置信息分析单元向区域业务管理单元发送位置更新至区域内通知，区域业务管理单元通知该用户加入业务；
2)组内用户执行终端开机，首次进入网络，用户归属MCPTT Server位置信息分析单元向区域业务管理单元发送位置更新至区域内通知，MCPTT Server业务管理单元通知该用户加入业务；
3)组内用户出受限区域时，用户归属MCPTT Server位置信息分析单元向区域业务管理单元发送位置更新至区域外通知，MCPTT Server业务管理单元需结束用户的业务，必要时，结束整个区域受限业务。
同时，业务进行时，组内用户释放/拒绝业务后，MCPTT Server区域业务管理单元周期通知用户加入网络。
实施例5和实施例6是区域严格受限的业务流程与框架，根据这个功能框架与流程，较容易地，业务受限区域可以设置为ECGI小区、GPS、公里标等形式，区域业务的管理仍然可以采用上述框架与分析过程，上述方法包含于此但是不限制于此。可以设置区域非严格受限的MCPTT业务需求，受限用户可在区域受限设置单元中设置组内人员权限，对组内权限高的成员设定区域不受限，部分组成员设定严格区域限制，MCPTT Server位置信息分析时，过滤区域不受限的用户的位置信息，仅仅分析严格受限的组成员，为业务区域管理单元提供区域管理人员参数，此种方法将更加灵活的满足实际集群用户组织的需要，同时，可防止移动业务用户位置信息上报过于集中带来的对网络的冲击。
本发明通过在MCPTT服务器预先设定受限区域、集群用户实时上报ECGI位置信息、GCSE AS维护业务区域内、业务区域外的组成员实例的方式，完成了集群区域业务的管理，满足了在MCPTT业务中对区域受限业务的需求。本发明定义了基于GCSE框架的受限区域业务的系统与系统管理方法，基于数据、语音以及多媒体的集群业务均可使用该组区域的设定方法，集群应用与LTE承载网络分离，架构更加合理。本发明填补了3GPP标准中MCPTT受限区域业务的空白，满足了业务严格受限集群用户的需求。另外，本发明的受限区域业务的定义放在应用层，与空口技术单播、多播技术无关；本发明中区域内人员的过滤管理与组成员中采用何种方式建立业务做到最低耦合，受限区域设定时可包含支持多播方案的区域，也可包含支持单播方案的区域，区域的单位为LTE网络的ECGI作为位置单位，兼容了大势所趋的多播技术方案的实现。再有，本发明的受限区域业务系统可融合到现有协议中的MCPTT业务架构，系统中区域管理与业务流程分离，模块设计合理，符合低耦合高内聚的设计思想，不影响3GPP协议的演进。
尽管为示例目的，已经公开了本发明的优选实施例，本领域的技术人员将意识到各种改进、增加和取代也是可能的，因此，本发明的范围应当不限于上述实施例。
