IA and key services, MIHF module is logically defined as a thin layer mobility management protocol stack in the terminal and the network plays in the handover decision process help function; to provide for multi-mode terminal, to the upper MIHF module needs to be done and how to make a handover decision information necessary handover decision, based on the upper and context MIHF module input link selection and handover decision made, in order to achieve seamless handover ; MIHF module mainly provides the following services to help users switching process:

[0004] 媒体无关事件服务(Media Independent Event Service,MIES):提供关于链路特征、链路状态和链路质量的动态变化事件的分类、过滤和报告; [0004] media independent event service (Media Independent Event Service, MIES): provides dynamic changes in the classification of events on link characteristics, link status and link quality, filtering and reporting;

[0005]媒体无关命令服务(Media Independent Command Service,MICS):提供MIH用户管理和控制与切换及移动性相关的链路行为的手段; [0005] Media Independent Command Service (Media Independent Command Service, MICS): means MIH user management and control of switching and mobility-related behavior of a link provided;

[0006]媒体无关信息服务(Media Independent Information Service,MIIS):提供服务网络和周围网络的特征和业务的详细信息,这些信息用于有效的系统接入和切换决定。 [0006] The media independent information service (Media Independent Information Service, MIIS): details and operational characteristics of the network services and the surrounding network, the information for system access and effective handover decisions.

[0007] 参阅图IA和图IB所示,通信系统中的用户终端和网络侧的各网元中均包含媒体无关切换(Media Independent Handover, MIH)用户模块和MIHF模块,MIH用户模块是属于层三(U)的移动性管理和应用协议,包括移动因特网协议(Mobile Internet Protocol, MIPv4/v6)和会话初始化协议(Session InitiatedProtocol, SIP)等移动性管理协议和切换策略、传输和应用等,MIHF模块就是提供媒体无关事件服务、媒体无关命令服务和媒体无关信息服务的媒体无关切换协议层。 [0007] Referring to FIG IA and FIG IB, the communication system of each network user terminal and the network element comprises both a media independent handover (Media Independent Handover, MIH) MIHF module and a user module, MIH layer belongs to the user module three (U) mobility management and application protocols, including mobile Internet protocol (mobile Internet protocol, MIPv4 / v6) and session Initiation protocol (session InitiatedProtocol, SIP) and other mobility management protocol and switching strategy, transfer and applications, MIHF module is to provide media independent event service, media independent media independent command service and information services media independent handover protocol layer. 其中,MIH用户模块与本地的MIHF模块之间通过MIH 原语(包括切换完成请求原语、切换完成指示原语、切换完成响应原语和切换完成确定原语)进行信息交互,本地的MIHF模块与远端对等的MIHF模块之间通过MIH消息(包括切换完成请求消息和切换完成响应消息)进行信息交互。 Wherein, between the MIH user module with local MIHF module MIH primitive (including a handover complete request primitive, a handover complete indication primitive, the handover complete response primitives and primitive handover completion determination) to exchange information, the local MIHF module between remote peer MIHF module exchanges information through MIH message (request message comprises a handover complete message and a handover complete response).

[0008] 在用户终端从源节点(如源网络)切换至目标节点(如目标网络)的过程中,当切换完成时,用户终端需向目标节点发送用于表示切换操作完成的切换完成请求消息,并由该目标节点通知相应的源节点释放关于该用户终端的网络资源,而所述切换完成请求消息是由用户终端上的MIHF模块根据本地的MIH用户模块下发的切换完成请求原语生成的, 目前,所述切换完成请求原语中未添加该用户终端的切换状态信息(包括切换失败、切换成功或切换拒绝),所以该用户终端不能通过切换完成请求消息将自身的切换状态信息发送给所述目标节点,因此,该目标节点也不能通知相应的源节点释放或/和维持所述用户终端的网络资源,这样,将造成所述源节点的承载负担;另一方面,由于源节点并未对该用户终端的网络资源作出任何处理,因此,该源节点无法 [0008] In the user terminal from a source node (e.g., source network) to the target node (e.g., target network) in the process, when the handover is completed, the user terminal to be sent to the target node for indicating completion of the switching operation of the handover complete request message by the corresponding notification destination node the source node to release network resources on the user terminal, and request the handover complete message by the user terminal MIHF module according completion issued by the local MIH user module handover request primitive is generated currently, the handover request primitive to complete the handover status information is not added to the user's terminal (including handover failure, or a handover reject successful handover), so that the user terminal can not complete the handover request message through its switching state information to the target node, and therefore, can not inform the target node of the corresponding source node to release network resources and / or maintain the user terminal, this will result in the source node carries the burden; on the other hand, since the source node did not make any deal with the network resources of the user terminal, therefore, can not be the source node 将用于表示处理结果的资源状态信息发送给所述目标节点,从而该目标节点无法通知相应的用户终端应如何继续相应的网络会话,这影响了整个切换流程的正常进行,进而影响了用户的使用体验。 Used to indicate the resource state information of the processing result is transmitted to the target node, such that the target node can not be notified how the respective user terminal should continue appropriate network session, which affect the normal operation of the entire switching process, thereby affecting the user's experience. 此外,当前标准中定义的机制,只能够处理终端只有单个会话切换的情况,对于用户终端有多个会话同时发生切换的情况不适用。 In addition, the mechanism defined in the current standard, where only capable of handling only a single terminal session switching, for the case where the user terminal has multiple sessions simultaneously switching is not applicable.
