Abstract
The invention proposes a method for routing sessions in a Session Initiation Protocol (SIP) used in a communication system, comprising the step of using a Globally Routable User Agent Uniform Resource Identifier (GRUU) for identifying the instance, wherein the Globally Routable User Agent Uniform Resource Identifier (GRUU) is related to a serving network control element of the instance. By this GRUU, a user equipment can be uniquely identified and a session can reliably be routed via the serving network control element such as an S-CSCF to the user equipment.
