Abstract:
1. A method for controlling communication between a number of first terminal modules connected to a multimedia IP network, comprising the steps of: establishing a first communications session between the first terminal modules, wherein the first communications session is a call session having a call session token; storing information related to the first communication session; receiving a request signal from one of the first terminal modules including a request to establish a second communication session, wherein the request signal is not a call request signal; selecting an application server based on a service type corresponding to the request signal; creating a service session token corresponding to the second communication session based on the service type; relating the service session token with the call session token; establishing the second communication session between at least a subset of the first terminal modules; storing relation information relating the first and the second communication sessions in an application session relation storage separate from the first terminal modules, wherein the relation information includes the call session token of the first communication session and the service session token of the second communication session; and automatically handing over the second communication session when the first communication session is handed over.
