Abstract: A mobile communications device and registration server and methods of use thereof. The mobile communications device comprises means for establishing a first data context and means for establishing a second data context. The first data context is established to transmit a request for parameters from the mobile communications device to a first network node and to receive at the mobile communications device a response from the first network node including the parameters. The second data context is established by transmitting the parameters from the mobile communications device to the second network node.

Abstract: A method and apparatus for dynamically modifying the quality of service (QoS) provided to a mobile communication device are disclosed. In one embodiment, a mobile communication device comprises a secure channel driver operable to establish a secure tunnel between the mobile communication device and a remote network via a wireless network, the secure tunnel operable to support multiple sockets opened therein; a first application operable to communicate with the remote network via a first socket within the secure tunnel and associated with a first QoS; a second application operable to communicate with the remote network via a second socket within the secure tunnel and associated with a second QoS, different from the first QoS; a QoS monitor operable to identify when the second QoS is appropriate to support the second application; and a QoS modification module operable to request the second QoS from the wireless network.
