Abstract

This paper presents an extension for Broadband Satellite Multimedia (BSM) to support Mobility Management (MM). To support seamless handovers, mobility related entities are proposed in the Satellite Independent Access Function (SIAF) defined over the SI-SAP interface. This enables the mapping of the mobility related primitives between the higher layer and the satellite dependant lower layers via the Satellite Dependent Access Function (SDAF). The proposed MM architecture incorporates the Media Independent Handover Services defined in the IEEE802.21 to support handover between different satellite systems. This includes definition of the Media Independent Handover Function (MIHF) which provides interworking between heterogeneous 802 networks and between 802 and other terrestrial mobile networks through the support of three services for handover, namely, Media Independent Event Services (MIES), Media Independent Command Services (MICS) and Media Independent Information Services (MIIS). A detailed description of the function architecture and a case study showing the signalling interaction between MIH and SI-SAP primitves are presented.

宽带卫星多媒体的移动扩展

本文提出了宽带卫星多媒体(BSM)支持移动管理(MM)的扩展方案。为了支持无缝切换，在SI-SAP接口上定义的卫星独立访问功能(SIAF)中提出了与移动性相关的实体。这使得可以通过卫星依赖访问函数(SDAF)在高层和依赖卫星的低层之间映射与移动性相关的原语。提出的MM架构结合了IEEE802.21中定义的媒体独立切换服务，以支持不同卫星系统之间的切换。这包括媒体独立切换功能(MIHF)的定义，该功能通过支持三种切换服务，即媒体独立事件服务(MIES)、媒体独立指挥服务(MICS)和媒体独立信息服务(MIIS)，在异构802网络之间以及802与其他地面移动网络之间提供交互。详细描述了功能架构和一个案例研究，显示了MIH和SI-SAP原语之间的信号交互。
