Description

一种集群通信的方法及系统、 用户设备和网络侧设备
技术领域
本发明涉及无线通信技术, 尤其涉及一种集群通信的方法及系统、 用户 设备和网络侧设备。
背景技术
集群通信系统是为了满足行业用户指挥调度需求而开发的、 面向特定行 业应用的专用无线通信系统, 系统中大量无线用户共享少量无线信道, 以指 挥调度为主体应用, 是一种多用途、 高效能的无线通信系统。 集群通信系统 在政府部门、 公共安全、 应急通信、 电力、 民航、 石油化工和军队等领域有 着广泛的应用市场。
集群通信系统经历了与蜂窝移动通信系统类似的发展历程。 第一代集群 系统是模拟集群通信系统, 主要支持语音通信。 最早进入我国的模拟集群通 信系统是 Nokia公司的 Actionet系统,它釆用 MPT- 1327信令,应用在 450MHz 频段上。 此后, 日本的 F.A.S.T和美国 Motorola公司的 Smartnet进入我国, 并长期占领我国集群市场 80%以上的市场份额。
第二代集群系统是窄带数字集群通信系统,兴起于 20世纪 90年代, 2004 年左右开始在我国部署, 是当前国内应用最广泛的集群通信系统。 数字集群 通信系统支持语音和低速数据(最高 28.8kbps )通信, 代表系统是欧洲电信 标准组织 ( European Telecommunications Standards Institute, ETSI )定义的陆上 集群无线电 ( Terrestrial Trunked Radio, TETRA ) 系统、 美国 Motorola的综合 数字增强型网络 ( Integrated Digital Enhanced Networks, iDEN ) 系统, 中兴通 讯股份有限公司基于 CDMA1X开发的开放式集群结构( Global Open Trunking Architecture, GoTa ) 系统、 华为技术有限公司基于 GSM开发的 GT800系统。 从国内来看, 最近两三年, TETRA网络的增长最快, 在全国已建的数字集群 通信网中, TETRA网的数量约占 2/3强。
集群系统区别于公众系统的特性在于,集群系统需要具备高效的指挥调 度特性, 并且要求网络具有高可靠性和安全性。
呼叫控制: 根据用户的业务请求, 在主叫用户和被叫用户之间建立、 维 持和释放业务承载;
鉴权认证: 支持鉴权和认证, 鉴权功能包括: 网络侧对终端鉴权, 以及 网络侧对终端和终端对网络侧的双向鉴权;
故障弱化: 当网络侧与基站或网络侧内部网元之间的链路发生故障时, 基站能够为其覆盖范围下的用户终端提供受限的集群服务。
网络互联互通功能: 能够与公共电话系统 (Public Switched Telephone Network , PSTN ) 、 公众移动通信系统( GSM/CDMA、 TD-LTE等) 、 IP电 话、 其他制式的集群通信系统等互通。 在 3GPP LTE中集群通信称为组通信 服务能力 GCSE, 图 1给出了 LTE GCSE的系统架构。
为了有效地利用移动网络资源, 第三代合作伙伴计划 (3GPP , 3rd Generation Partnership Project ) 提出了多媒体广播多播业务 ( MBMS , Multimedia Broadcast Multicast Service ) , 该业务是一种从一个数据源向多个 目标移动终端传送数据的技术, 实现了网络(包括核心网和接入网 ) 资源的 共享,提高了网络资源(尤其是空中接口资源)的利用率。 3GPP定义的 MBMS 业务不仅能够实现纯文本低速率的消息类组播和广播, 而且还能够实现高速 多媒体业务的广播和组播, 提供多种丰富的视频、 音频和多媒体业务, 这无 疑顺应了未来移动数据发展的趋势, 为 3G的发展提供了更好的业务前景。
MBMS业务的特点是业务的数据量大, 移动终端接收时持续时间长, 平 均数据率恒定。上述特点决定了 MBMS业务的调度与控制信令配置都是半静 态的, 即 MBMS业务的调度信息与控制信令信息都是 "长期" 保持不变的, 这些信息通过 MBMS控制信道( MCCH, MBMS Control Channel )周期性地 发送, 统称为 MCCH信息。 演进型 MBMS ( eMBMS ) 系统可能存在多个 MCCH, 每个 MCCH对应于不同的 MBSFN区域, 其中仅承载对应 MB SFN 区域发送的 MBMS业务的控制信息。 图 2给出了 LTE中 MBMS的架构示意 图。
目前业界正在讨论釆用 MBMS技术实现集群通信的可能性。 在对相关技术的研究和实践过程中发现相关技术存在以下问题: 例如, 当通过 MBMS承载接收集群服务的 UE移动到 MBMS覆盖区域 外或 MBSFN信号质量差时, 如何通知集群应用服务器? 如何保障集群服务 连续性? MBMS承载的集群通信如何切换到单播承载的集群通信? 等等。即, 当通过 MBMS承载接收集群服务的 UE不再具备通过 MBMS承载接收集群 服务的条件时,如何实现集群通信? 这一问题在相关技术中尚没有解决方案。

本发明的较佳实施方式
下文将结合附图对本发明技术方案作进一步详细说明。 在不冲突的情况 下, 本申请的实施例和实施例中的特征可以任意相互组合。
实施例 1 本实施例提供一种集群通信的方法, 如图 3 ( a )所示, 包括如下操作: 步骤 101 , 注册到某个集群业务(GCSE group communication ) 的 UE, 简称为集群 UE, 感兴趣接收或者正在接收 MBMS承载上的集群业务;
首先说明一下 , 本发明的 MBMS是指演进的 MBMS即 eMBMS。
步骤 101之前,所述集群 UE首先注册到 GCSE AS。这样 GCSE AS可以 知道一共有多少 UE加入了一个集群业务。 UE感兴趣接收是指 UE准备接收。
所述 UE正在接收集群业务是指: UE在 MBMS覆盖区域通过 MBMS承 载接收集群服务。 所述 UE具有集群通信能力和 MBMS能力, 包括用户终端 和调度台, 用户终端包括手持终端、 车载台和固定台等; 调度台包括有线调 度台和无线调度台。 用户终端和无线调度台通过空中接口与 LTE网络相连, 有线调度台通过集群网关与网络子系统相连。
所述 MBMS承载包括核心网承载(即: EPC承载)和空口承载, RAN (基站 eNB或 MCE )配置 MBMS空口资源,并在空口发送 MBMS配置信息 和集群数据。
而本实施例中, 集群 UE感兴趣接收或者正在接收的 MBMS承载上的集 群业务是指:
集群 UE在 MBMS覆盖区域内通过 MBMS承载感兴趣接收或正在接收 的集群服务。
步骤 102, 集群 UE判断是否需要通过单播承载传输集群业务;
集群 UE判断出需要通过单播承载传输所述集群业务的过程如下: 集群 UE根据自身判断符合以下 6种情况中的任意一种,集群 UE就可以 确定需要通过单播承载传输所述集群业务:
1、 UE离开承载集群业务的 MBSFN区域,也就是 UE不在该 MBSFN区 域覆盖范围内。 在实际网络中, 不同的集群业务可以配置在不同的 MBSFN 区域, 为了描述方便, 本发明实施例中所指的 MBSFN区域, 是指: 承载步 骤 101中的集群业务的 MBSFN区域。
集群 UE判断其自身是否离开所述 MBSFN区域的方法包括:
1 ) UE在本小区没有发现或无法读取配置 MBMS参数的相关系统广播 消息 (如: SIB13或 SIB15 ) ; 2 )或 UE在本小区没有发现或无法读取 MCCH;
3 )或: UE在本小区通过读取系统广播消息(如: SIB15 ) , 发现本小区 所属于的 MBMS业务区域( SAL service area ID ) 不属于该集群业务的广播 区域。
4 )或 UE在本小区所读取 MCCH中, 没有该集群业务的配置参数。
2、 集群 UE确定 MBSFN信号质量差。
UE在 MBSFN区域,基于对 MBMS信号的测量,判断所接收到的 MBSFN 信号质量不好;
3、集群 UE位于 MBSFN区域边界小区( UE读取到 MBSFN区域边界小 区的标识) ;
其中, 所述 MBSFN区域边界小区, 是指承载步骤 101 中的集群业务的 MBSFN区域的边界小区
所述边界小区通过广播消息指示 MBSFN区域边界标识; 也可以通过专 用信令由网络指示该 UEMBSFN区域边界标识。
4、 集群 UE自身没有 MBMS能力;
5、 集群 UE向网络(如: GCSE AS ) 申请话权, 以便获得话权后发送上 行数据
一个用户先通过 MBMS承载接收下行组呼数据;
UE建立 unicast承载向 AS申请话权;
UE获得话权后发送上行数据;
上行数据传输结束时, UE可以与 AS协商,是否继续通过 unicast承载接 收数据还是回到 MBMS承载接收方式。
6、 集群 UE认为需要建立单播承载的其他原因。 例如, 高优先级任务、 延时敏感任务等。
步骤 102, 如果需要通过单播承载传输集群业务, 则向集群应用服务器
( AS )发送通过单播承载传输集群业务的请求;
步骤 103 , 当网络侧 AS与所述集群 UE建立单播承载后, 所述集群 UE 通过所述单播承载接收集群数据, 并停止接收 MBMS承载上的集群数据。 当网络侧 AS未与集群 UE建立单播承载时 , 则所述集群 UE通过已有的 MBMS承载接收集群数据即可。
集群 UE向 AS发送通过单播承载传输集群业务的请求包括: 集群 UE从 空闲态转到连接态时, 通过应用层信令或者 EPS信令向 AS发送建立单播承 载的请求, 其中, EPS信令包括空口信令和 EPC信令。
上述方法, 主要从集群 UE侧来描述集群通信的过程, 本实施例再介绍 另一种集群通信的方法, 主要从网络侧进行描述, 该方法如图 3 ( b )所示, 包括:
步骤 104, 集群应用服务器(AS )接收集群用户设备 ( UE )发送的通过 单播承载传输集群业务的请求;
步骤 105, AS根据集群 UE的请求信息和本地信息确定需要釆用单播承 载传输集群数据, 则在网络侧与集群 UE之间建立单播承载;
本实施例中, 网络侧 (AS )收到 UE的上述请求后, 判断是否需要为该 UE建立单播承载, 其判断方法是: 判断是否有可用的 MBMS承载(也就是: 多播承载, Multicast bearer, 是相对于单播承载的多播承载, 也称为 PTM点 到多点承载 )或可建 MBMS承载: 可用的 MBMS承载是指 UE在 MBMS覆 盖区域(MBMS覆盖区域就是 MBSFN area ) , 集群业务已开始还未结束; 可建 MBMS承载是指 UE在 MBMS覆盖区域, 集群业务还未开始。 如果没 有可用或可建 MBMS承载, 则建立单播承载, 如果有可用或可建 MBMS承 载, 则继续釆用 MBMS承载。
另夕卜,如果 AS根据集群 UE的请求信息和本地信息确定不需要釆用单播 承载传输集群数据, 则通过已有的多媒体广播多播业务(MBMS )承载向所 述集群 UE传输集群数据即可。
步骤 106, AS通过单播承载向集群 UE传输集群数据。
AS根据 UE的请求信息和本地信息确定是否釆用单播承载, 如果 UE指 示处于 MBMS覆盖区域之外, 且 AS中的集群服务未结束, 则 AS选择通过 单播承载发送集群服务。
UE通过单播承载接收集群数据,并停止接收 MBMS承载上的集群数据。 下面通过集群业务流程的实施例来说明本发明的方案。
针对 UE正在通过 MBMS承载接收集群服务的场景, 实现集群通信的方 法如图 4所示, 包括:
步骤 201 , UE通过 MBMS承载接收集群服务。
所述 UE在 MBMS覆盖区域, 并通过所述 MBMS承载接收集群服务。 步骤 202 , UE测量 MBMS信号质量。
所述 UE对接收的 MBMS承载信号质量进行测量, 其中 MBMS承载信 号质量参数包括以下任意一种或几种:
MBSFN 参考信号接收功率 (RSRP ) 、 MBSFN 参考信号接收质量 ( RSRQ ) 、 MBSFN接收信号强度指示 ( RSSI ) \MBSFN参考信号信嗓比 ( RS SNR ) 、 MBSFN块误码率( BLER ) 。
所述测量方法为以下任意一种: 周期测量、 事件触发测量或上述两种方 法的结合。
步骤 203 , UE判断 MBMS信号质量是否满足要求, 如果是, 转向步骤 209, 否则转向步骤 204。
所述 UE判断 MBMS信号质量是否满足集群业务接收要求, 可以以指定 门限要求为例来说明。 所述指定门限是指事先确定的数值, 如通过 OAM指 定的门限数值, 针对不同的测量参数有不同的指定门限。 如果测量参数值 MBSFN RSRP, MBSFN RSRQ, MBSFN RSSI, MBSFN RS SNR低于指定门 限,或者,如果测量参数值 MBSFN BLER高于指定门限,则均为不满足要求, 否则均为满足要求。
步骤 204, UE是否为空闲态, 如果是, 则转向步骤 205, 如果不是, 则 转向步骤 206。
所述 UE可以是空闲态或连接态。
步骤 205, UE进入连接态。
如果所述 UE为空闲态, 则 UE进入连接态。
步骤 206, UE向集群应用服务器 AS发送请求信息。
所述 UE通过应用层信令或 EPS信通知 AS:请求建立单播承载发送集群 数据。
步骤 207 , AS向 UE发送响应信息。
