【摘要】：IMS网络强调终端智能,通常每一类应用业务都需要使用专用的IMS终端,以便进行IMS业务的特征展现和功能交互。IMS业务多样化,如数据会议业务、在线教育业务、高清视频业务、视频监控业务等等。当在一个IMS用户设备(智能手机、PC等)上,运行多个不同IMS业务终端时,这实际上对IMS终端技术提出了挑战。带来的主要问题是：(1)多重注册和信令冗余：每一个业务终端都需要将IMS用户身份注册到IMS核心网,独立的注册流程必然造成额外的信令开销,导致信令冗余,缺乏效率。(2)资源争用：多个业务终端进行通信时,依据业务特性的不同,需要占用不同的设备资源(如麦克、扬声器、显示设备等)。当多个业务终端要同时进行通信时,使得各个业务对设备上资源的争用难以避免。(3)业务重叠和应用冲突：用户设备上所有业务终端共用同一个公共用户标识,即所有的业务终端使用同一个账号与外界进行通信。由于IMS业务重叠,不同的业务终端具有一些相似的功能,当其他用户对该用户发起呼叫请求时,可能激活不合适的业务终端与之通信,而导致会话异常,严重影响用户体验。本文从三个方面深入研究多终端协同技术,设计统一注册机制,规范IMS终端的资源管理规则,设计业务终端触发机制,并提出一种基于B2BUA功能实体的协同设计方案。本文主要完成如下工作：1)通过提取注册消息中的相关信息构造注册管理信息表,依据注册管理信息表设计协同注册规则,并设计针对多业务终端的协同注册流程。2)针对不同的业务终端对资源的需求,设计资源管理协调规则,包括构造终端资源信息表以及资源占用信息。3)根据IMS业务过滤规则,并结合IMS业务特性,针对业务终端设计新的终端触发条件,根据触发条件对不同的业务终端进行匹配,选出合适的业务终端进行通信。4)通过对B2BUA功能实体的深入研究,提出一种基于B2BUA功能实体的解决方案。设计协同模块包括：实体模块(my_entity);逻辑模块(my_logic)。通过该协同模块实现对多终端注册和会话流程的管控,以及对设备资源进行统一管理。通过搭建原型系统进行测试验证,结果表明本文所提出的解决方案具有合理性和可行性,能够解决同一用户设备上的多个业务终端的协同问题。
[Abstract]:The IMS network emphasizes terminal intelligence, and each application service needs to use a special IMS terminal, so as to display the features of IMS service and diversify its function interaction, such as data conference service, online education service, high-definition video service, etc.Video surveillance business and so on.When running multiple different IMS service terminals on a IMS user device (smart phone PC etc.), this actually challenges the IMS terminal technology.The main problems are: 1) multiple signalling and signalling redundancy: every service terminal needs to register the IMS user identity into the IMS core network, and the independent registration process will inevitably cause additional signaling overhead and lead to signaling redundancy.Lack of efficiency. 2) Resource contention: when multiple service terminals communicate, different equipment resources (such as Mike, loudspeaker, display device, etc.) need to be occupied according to different service characteristics.When multiple service terminals want to communicate at the same time, it is difficult for each service to compete for resources on the device to avoid overlapping services and application conflicts: all service terminals on the user equipment share the same common user identity,That is, all business terminals use the same account to communicate with the outside world.Because of the overlap of IMS services, different service terminals have some similar functions. When other users initiate a call request to the user, they may activate an inappropriate service terminal to communicate with them, resulting in a session exception, which seriously affects the user experience.In this paper, the cooperation technology of multi-terminal is deeply studied from three aspects, the unified registration mechanism is designed, the resource management rules of IMS terminal are standardized, the trigger mechanism of business terminal is designed, and a collaborative design scheme based on B2BUA functional entity is proposed.The main work of this paper is as follows: (1) the registration management information table is constructed by extracting the relevant information from the registration message, and the cooperative registration rules are designed according to the registration management information table.According to the resource requirement of different service terminals, the coordination rules of resource management are designed, including constructing terminal resource information table and resource occupying information. 3) according to the IMS service filtering rules, this paper designs a collaborative registration process for multi-service terminals.A solution based on B2BUA functional entity is proposed.The design cooperation module includes: entity module and logic module.Through the cooperative module, the multi-terminal registration and session flow can be controlled, and the equipment resources can be managed uniformly.The results show that the solution proposed in this paper is reasonable and feasible, and can solve the cooperation problem of multiple service terminals on the same user equipment.
