Abstract
The present invention relates to a method and system for activating a context in a first network so as to transfer a call and/or a transaction via said first network and a second network. Initially, an application protocol such as H.323, H.248 or SIP is set up using a signaling or default context within the first network. Based on a message of the application protocol transmitted from the second network, a capability information is determined and used to activate the context. Thereby, the capabilities can be agreed in advance and the context can be activated e.g. as a secondary context for both mobile-originated and mobile-terminated calls and/or transactions. Accordingly, a reservation protocol is no longer required to signal the capability requirements to the second network, and signaling load can be decreased.
