In the present invention, the layer 2 the mobile network is an IP sub-network, the core network of the ring-shaped connecting Layer 2 switching segments independent multiple Layer 2 switching segments (31) and (31) between (32) and is adapted to be controlled is composed of a, with ...
We use Mobile-IP as the basis for providing mobility for nomadic users, and extend it to facilitate additional services for nomadic users both at the network layer and above. As an example of how Mobile-IP can be useful with other protocols at the network layer, we show how Mobile-IP ...
Mobile IP enables an IP node to retain the same IP address and maintain existing communications while traveling from one link to another. Mobile IP is an IETF standards based solution for mobility at the network layer, which is Layer 3. Mobile IP supports the following RFCs: R...
Network layer indications are not readily available upon a link change; therefore, general dependence on the network layer may introduce unnecessary delays due to network layer signaling for a simple link layer handoff. If information could be gathered at link layer to determine the need for network...
We report our results which show that fast handovers with context transfer at the network layer can support uninterrupted voice over IP (VoIP). Thus, our context transfer framework will catalyze the arrival of a unified wireless telecommunications network, with voice and data connectivity anytime,...
Because the mobility functions of Mobile IP are performed at the network layer rather than the physical layer, the mobile device can span different types of wireless and wireline networks while maintaining connections and ongoing applications. Remote login, remote printing, and file transfers are some...
Mobile IPv6 is a network-layer mobility protocol for the IPv6 Internet. The protocol includes several security mechanisms, such as the return-routability t... Tuomas AURA,Michael ROE - 《Annales Des Télécommunications》 被引量: 64发表: 2006年 Problem Statement for bootstrapping Mobile IPv6 (...
Although Session Initiation Protocol (SIP) based mobility solution is very efficient for real-time services, Mobile IP is required to handle mobility of the mobile node (MN) at the network layer. We have extensively studied and explored some existing mobility management methods integrating the ...
To easily provide consistent end-to-end QoS across a UMTS layer and an IP layer on a mobile network. ! An NOC policy server (200) is used to map QoS parameters between a mobile network (110) and a data network (140, 145) and between a UM... 3rd Generation Partnership Project (3GPP...
Mobile IP (MIP) provides efficient mobility support to applications at transport layer or above. MIP can provide better quality of service (QoS) in heterogeneous environment if it relies on layer 3 based movement detection techniques. Among the existing movement detection algorithms (MDAs), enhanced...
