A communication system reduces set up time for an inter-technology handoff of a multi-mode mobile station (MS) from a source network associated with a first radio frequency (RF) technology to a target network associated with a second RF technology by pre-establishing, prior to a determination to handoff the MS, a registration state of the MS and an authentication of the MS in association with the target network and second RF technology. In order to pre-establish the registration state and authentication, the MS exchanges messaging of the second RF technology with the second network via the first network and first RF technology. To facilitate the exchange, the MS includes shims in a second protocol stack associated with the second technology, which shims intercept second protocol stack signaling and redirect the intercepted signaling to a first protocol stack of the MS, associated with the first technology, for tunneling to the source network.

Method and apparatus for inter-technology handoff of a multi-mode mobile station

A wireless data network process and system are provided based on a network with prior network-based authentication of a connected mobile node (MN) and with a network connection to a packet gateway node (PGN). The method and system establish and use an authentication mechanism between the MN and the PGN using the network connection. An encrypted channel is then set up between the MN and the PGN based on authentication established with the authentication mechanism. Configuration data is sent from the PGN to the MN using the encrypted channel. The configuration data may then be used by the MN for communication to and from the MN with the PGN via an access point. Any network connected to the PGN via any access point may then be used.

System and method for secure network roaming

A first data stream ( ) requested by a first client ( ) is received at a router ( ). A second data stream ( ) requested by a second client ( ) is also received at the router ( ). The router ( ) determines that the first data stream ( ) and the second data stream ( ) are identical. The router ( ) multicasts the first data stream ( ) and the second data stream ( ) into a single multicast data stream ( ). The single multicast data stream ( ) is transmitted to the first client ( ) and to the second client ( ).
