針對無線區網地域性以及群播應用所設計之SIP-Based行動管理平台之實作

A SIP-Based Mobility Management Platform for WLAN Location-Aware Broadcasting and Multicasting Applications

指導教授 : 林風

摘要


隨著無線區域網路 (Wireless Local Area Network) 的快速發展,無線區域網路的使用越顯普及,同時使用者對於無線區域網路中的智慧型應用也深切期待。其中,在地性 (Location-Aware) 應用被視為未來無線網路中重要的一殺手級應用。此論文提出一針對無線區網在地性應用所設計與實作之一SIP-based行動管理平台,並將此平台命名為 “WLB”。我們設計了行動性管理、廣播與群播機制於WLB平台,以將WLB平台中的在地岍野庛穈T提供給平台中的行動使用者。WLB平台在應用層 (Application Level) 將無線區域網路區分成多個服務區域。在WLB平台中的訊號傳遞都是透過SIP (Session Initialization Protocol),使得WLB平台能夠與其他的行動通訊網路進行整合 (例如,全球行動電信系統 (UMTS) 以及一般封包式無線服務 (GPRS))。在此論文中,我們詳細的描述WLB平台之設計與實作,並針對WLB平台與全球行動電信系統整合架構進行討論。

Recently, as the service areas of Wireless Local Area Network (WLAN) increase rapidly, the usage of WLAN gets popular. People expect more intelligent applications on WLAN. The location-aware application is one of the killer applications. This paper proposes a SIP-based mobility management platform named ``WLB" for WLAN location-aware applications. The WLB accommodates the mobility management, broadcasting, and muticasting mechanisms for mobile user. Within the WLB, the coverage areas of WLANs are partitioned into several service areas on the application level. All signaling in WLB is based on Session Initialization Protocol (SIP), which extends the capability of WLB to be integrated with other mobile networks (e.g., UMTS and GPRS). In this paper, we detail the design and implementation of the WLB platform and discuss a possible integration of the WLB with UMTS all-IP network.
