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.

Apparatus and methods for over the air provisioning of a single PDP context mobile communications device

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.
