Description

一种集群业务处理方法和***  Cluster business processing method and system
技术领域 Technical field
本发明涉及 LTE ( long term evolution, 长期演进） 集群***， 尤其涉及 一种集群业务处理方法和***。  The present invention relates to an LTE (long term evolution) cluster system, and in particular, to a cluster service processing method and system.
背景技术 Background technique
LTE集群是指使用 LTE相关的技术， 完成集群功能。 集群通信***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 ***， ***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***。 集群通信***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。  LTE cluster refers to the LTE-related technology to complete the cluster function. The trunking communication system is a dedicated wireless communication system developed for industrial users' command and dispatching needs for specific industry applications. A large number of wireless users share a small number of wireless channels in the system, and the command and dispatch is the main application. It is a multi-purpose and high-efficiency system. Wireless communication system. The trunking communication system has a wide application market in the fields of government departments, public security, emergency telecommunications, electric power, civil aviation, petrochemicals and military.
集群通信***经历了与蜂窝移动通信***类似的发展历程。 第一代集群 ***是模拟集群通信***， 主要支持语音通信。 最早进入我国的模拟集群通 信***是 Nokia公司的 Actionet***，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。  The trunked communication system has undergone a similar development process as cellular mobile communication systems. The first generation cluster system is an analog trunking communication system that mainly supports voice communication. The first analog trunk communication system that entered China was Nokia's Actionet system, which used MPT-1327 signaling and was applied in the 450MHz band. Since then, F. A. S. T of Japan and Smartnet of Motorola of the United States have entered China.
第二代集群***是窄带数字集群通信***，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***。 数字集群 通信***支持语音和低速数据（最高 28.8kbps )通信， 代表***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 ) ***、 美国 Motorola的综合 数字增强型网络 ( Integrated Digital Enhanced Networks, iDEN ) ***， 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 ) ***、 华为技术有限公司基于 GSM开发的 GT800***。 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。  The second-generation cluster system is a narrow-band digital trunking communication system. It started in the 1990s and began to be deployed in China around 2004. It is the most widely used cluster communication system in China. The digital trunking communication system supports voice and low-speed data (up to 28.8 kbps) communication. The representative system is the Terrestrial Trunked Radio (TETRA) system defined by the European Telecommunications Standards Institute (ETSI), and the integration of Motorola in the United States. Integrated Digital Enhanced Networks (iDEN) system, ZTE Corporation's Global Open Trunking Architecture (GoTa) system based on CDMA1X, and GT800 system based on GSM developed by Huawei Technologies Co., Ltd. Domestically, the TETRA network has experienced the fastest growth in the last two or three years. In the digital trunking communication network built nationwide, the number of TETRA networks accounts for about two-thirds.
从目前我国集群通信***的发展来看， 集群通信***的发展远远落后于 公众蜂窝***的发展， 其技术创新和产业链等方面都还不尽完备。 在数据传 输能力和多媒体业务的支持能力方面， 目前的数字窄带集群通信***仍然比 较落后。例如， iDEN***对时隙和调制方法进行改进后而推出的宽带综合数 字增强型网络（Wide-iDEN, WiDEN ) , 将峰值传输速率提高至 384kbps; TETRA增强型数据业务（ TETRA Release 2 Enhanced Data Service, TEDS ) , 理想情况下可支持不超过 700kbps的峰值传输速率；均未达到 Mbps的数量级。 此外， 在频谱利用率和覆盖方面， 现有的数字集群***也不能很好的满足需 求。 From the perspective of the development of China's trunking communication system, the development of the trunking communication system lags far behind the development of the public cellular system, and its technological innovation and industrial chain are still not complete. Data transmission In terms of capacity and multimedia service support capabilities, the current digital narrowband trunking communication system is still relatively backward. For example, the iDEN system improves the time slot and modulation method and introduces a broadband integrated digital enhanced network (Wide-iDEN, WiDEN) to increase the peak transmission rate to 384 kbps. TETRA Enhanced Data Service (TETRA Release 2 Enhanced Data Service) , TEDS ) , ideally supports peak transmission rates of up to 700 kbps; none of them reach the order of Mbps. In addition, existing digital trunking systems are not well suited to demand in terms of spectrum utilization and coverage.
LTE技术推出之后，***带宽下行超过 100Mbps,上行带宽超过 50Mbps, 呼叫建立时间短， 小于 100ms, 这样满足宽带集群***的特征： 集群通信系 统以半双工方式通信， 工作时通过即按即说（Push To Talk, PTT )键控制信 道的获取和释放， 信道利用率高， 呼叫接续快； 组内用户共享下行信道， 资 源利用率高。 而且， 集群通信***可以通过话音加密保证通话的私密性和安 全性； 为高优先级用户或业务优先分配信道； 通过故障弱化功能保证紧急状 态下的通信； 通过动态重组实现灵活的多级别分组调度指挥功能； 宽带集群 通信***围绕 "语音" 、 "数据" 、 "视频" 这三个基本服务拓展宽带业务 类型， 包括： 组呼 /可视组呼、 单呼 /可视单呼、 紧急呼叫等语音类业务； 移动 信息服务、 高速数据查询、 网络浏览、 移动办公、 定位服务等数据类业务； 视频会议、 移动视频监控等视频类业务； 具有群呼、 直呼等快速指挥调度能 力； 集语音、 数据、 图像和视频的多业务传输能力； 具有网络互联和脱网通 信能力， 以支持直通或终端构建 Mesh 网络等； 网络可靠性高， 具有强故障 弱化和抗毁能力； 支持大热点地区、 热点时段的大话务量能力； 呼叫建立短， 单***呼叫建立时间小于 300ms。  After the introduction of LTE technology, the system bandwidth downlink exceeds 100Mbps, the uplink bandwidth exceeds 50Mbps, and the call setup time is short, less than 100ms, which satisfies the characteristics of the broadband cluster system: The trunking communication system communicates in a half-duplex mode, and the push-and-talk is performed during work ( Push To Talk, PTT) key control channel acquisition and release, high channel utilization, fast call connection; users in the group share the downlink channel, high resource utilization. Moreover, the trunking communication system can guarantee the privacy and security of the call through voice encryption; preferentially allocate channels for high-priority users or services; ensure communication under emergency conditions through fault weakening function; realize flexible multi-level packet scheduling through dynamic reorganization Command function; Broadband trunking communication system expands broadband service types around three basic services: "voice", "data", and "video", including: group call/visual group call, single call/visible single call, emergency call, etc. Voice services; mobile information services, high-speed data query, web browsing, mobile office, location services and other data services; video conferencing, mobile video surveillance and other video services; with group call, direct call and other fast command and dispatch capabilities; Multi-service transmission capability of data, image and video; with network interconnection and off-network communication capability to support direct or terminal construction of Mesh network; high network reliability, strong fault weakening and anti-destruction capability; support for hot spots, Large traffic capacity during hotspots; call setup Short, single system call setup time is less than 300ms.
LTE集群将继承 LTE技术的先进性， 釆用扁平的网络架构， 降低业务接 入延迟。 如图 1所示， LTE集群网络包含 MME、 SGW ( serving gateway, 服 务网关）、 eNB ( evolved Node B演进的基站）和集群调度部分， 以及集群终 端。现有技术中， LTE集群引入了两个传输信道：集群控制信道（ Trunk Control Chanel, TCCH )和集群业务信道（ Trunk Traffic Chanel, TTCH ) , 在 TCCH 上实现组呼的建立和释放、 话语权的通知， 这种方法在单向信道传输信令存 在很大风险， 例如， 如果消息丟失， 会造成状态机出现问题， 多个终端的状 态出现不一致；在 TCCH发送 TTCH的配置，在 LTE***中一般不这样实现， LTE釆用盲检的方法实现，简化配置，目前这样的实现方式没有充分利用 LTE 的特性。 如何将集群和 LTE充分结合， 发挥 LTE在集群的优势， 这是一个需 要商榷的内容。 The LTE cluster will inherit the advanced nature of LTE technology and adopt a flat network architecture to reduce service access delay. As shown in FIG. 1, the LTE cluster network includes an MME, a SGW (serving gateway), an eNB (evolved Node B evolved base station), and a cluster scheduling part, and a cluster terminal. In the prior art, the LTE cluster introduces two transport channels: a trunk control Chanel (TCCH) and a trunk traffic Chanel (TCCH), which implements group call establishment and release, and voice rights on the TCCH. It is noted that this method has a great risk in transmitting signaling on a unidirectional channel. For example, if a message is lost, it will cause a problem with the state machine. The state is inconsistent; the configuration of transmitting TTCH in the TCCH is generally not implemented in the LTE system, and the LTE is implemented by the blind detection method, which simplifies the configuration. Currently, such an implementation does not fully utilize the characteristics of the LTE. How to fully integrate cluster and LTE, and take advantage of LTE in the cluster, this is a content that needs to be discussed.
