WGSN: WLAN-based GPRS Support Node with Push Mechanism

Abstract

This paper proposes wireless LAN (WLAN)-based GPRS Support Node (WGSN), as a solution for integrating Third Generation (3G) and WLAN services. We show that the 3G mechanisms can be re-used for WLAN user authentication and network access without introducing new procedures and without modifying the existing 3G network components. We describe the WGSN features and show how they are designed and implemented. To reduce the power consumption and computation complexity of a mobile station (MS), the WGSN applications may not be activated in the MS if they are not used. For an MS-terminated application, a push mechanism is implemented in WGSN, which automatically activates the application at the MS side. An analytic model is proposed to investigate the requirements on the WGSN transmission delay of the push operation. A WGSN prototype has been implemented in the

QoE-Aware Mobility Management Scheme

“…In addition, a considerable amount of research effort has been dedicated to the investigation of energy management, usually called power saving, schemes in multi-interface systems [12][13][14][15][16][17][18]. However, most of this effort has been focused only on the energy saving issue of multi-interface systems without the QoE concern, i.e., delay of the incoming service through the interface already turned into the energy saving mode.…”

Secure push for mobile airline services

“…Feng et al [7] have proposed a solution for integrating 3G and WLAN services. They have made a survey indicating that 3G/WLAN interworking, more specifically accessing 3G packet-switched services over WLAN, is essential for commercial operations.…”

“…Therefore, a user must ask for the floor (the permission to speak) by pressing the push-to-talk button before he/ she starts to talk. In this paper, we implement a PoC client in the WLAN environment [1] with some variation from the open mobile alliance (OMA) PoC specifications v1.0 release [2]. The PoC architecture is illustrated in Figure 1.…”

“…Our design uses SIP instead of HTTP and RTCP, so that we can develop the PoC client directly from the standard VoIP modules. This paper proposes a PoC client architecture for mobile terminal targeted at the cellular network [6] or WLAN [1]. An OSA-based PoC server architecture is described in References [7,8].…”
