ABSTRACT:
A method for distributing a session key across GateKeeper (GK) zones in a direct-routing mode, including the following steps: a caller's GK and a callee's GK determine a session key distributing mode for a caller and a callee to distribute the session key according to information contained in a received message and pre-configured rules for selecting the session key distribution mode. An embodiment of the present invention also provides a system for distributing a session key across GK zones in a direct-routing mode. The method and the system make it possible for the caller's GK and the callee's GK to select the session key distribution mode, and improves the flexibility of the session key distribution for the GKs.
