Abstract:
1. A method comprising: setting up a first part of a multi-media call utilizing packet-switched resources on a communication network; setting up a second part of the multi-media call utilizing circuit-switched resources on the communication network; wherein call control for the multi-media call is handled by a single point of control, and wherein said single point of control reallocates packet-switched resources and circuit-switched resources for the multi-media call, and wherein said single point of control waits for circuit-switched resources to become available while resources are changed to packet-switched resources, and wherein said single point of control allocates packet-switched resources and circuit-switched resources independently for different parts of the multi-media call, and wherein said single point of control blocks new calls while resources are changed from circuit-switched resources to packet-switched resources.
