Method and system for activating a packet data subscriber context for packet data

A system for activating a context in a first network so as to transfer at least one of a call and a transaction via said first network and a second network, comprising:

• setup means for transmitting, from a calling equipment, a set-up message according to an application protocol using a signaling or default context within said first network;
• determination means for determining capability information based on a message of said application protocol transmitted from said second network to said first network without requiring a reservation protocol for reserving resources along an intermediate route between the first and second network;
• and
• activation means for activating said context based on said determined capability information;
• wherein said application protocol is set-up between the calling equipment and called equipment before activating said context.

A terminal device for activating a context in a first network so as to transfer at least one of a call and a transaction via said first network and a second network, said terminal device comprising:

• determination means for determining capability information based on a message, from a calling equipment, of an application protocol transmitted from said second network via said first network to said terminal device, wherein a signaling or default context is used within said first network without requiring a reservation protocol for reserving resources along an intermediate route between the first and second network;
• and
• activation means for activating said context using said determined capability information;
• wherein said application protocol is set-up before activating said context.

A method for activating a context in a first network so as to transfer at least one of a call and a transaction via said first network and a second network, said method comprising:

• transmitting, from a calling equipment, a set-up message according to an application protocol using a signaling or default context within said first network;
• determining capability information based on a message of said application protocol transmitted from said second network to said first network;
• setting up the application protocol between the calling equipment and called equipment before activating said context;
• and
• activating said context based on said determined capability information.

A terminal device for activating a context in a first network so as to transfer at least one of a call and a transaction via said first network and a second network, said terminal device comprising:

• a transmission unit configured to transmit, from a calling equipment, a set-up message according to an application protocol using a signaling or default context within said first network;
• a determination unit configured to determine capability information based on a message, from a calling equipment, of an application protocol transmitted from said second network via said first network to said terminal device;
• and
• an activation unit configured to activate said context using said determined capability information;
• wherein said application protocol is set-up before activating said context.
