Patent ID: 7447776

Claim:
A method of arranging transmission of packet-switched data in a packet radio system having at least one mobile termination part operatively associated with a terminal equipment part for communication in a packet switched radio network, the method comprising: activating a first packet data protocol context between said packet radio network and the mobile termination part for reception and transmission of packet-switched data, storing parameters relating to said first packet data protocol context; activating a second packet data protocol context between the packet radio network and the mobile termination part to establish a dial-up connection by a link between the terminal equipment part and the mobile terminal part or the terminal equipment part and the packet radio network, releasing said first packet data protocol context in response to said second packet data protocol context being activated, in order to minimize processor and memory loading and avoid expense, releasing the dial-up connection, releasing said second packet data protocol context in response to the dial-up connection being released, and activating a third packet data protocol context, using said stored parameters relating to said first context, in response to said second packet data protocol context being released, and wherein the terminal equipment part and a packet network gateway support node (GGSN) support a PPP protocol (Point to Point Protocol), whereby said second context is activated for setting up a dial-up connection between the mobile termination part and the GGSN, a PPP link is set up between the terminal equipment part and the GGSN, and data associated with an application comprised by the terminal equipment part is transmitted by means of the PPP link and said second context.
