Method for the routing of multimedia communication related signaling in a communication system

摘要

The invention relates to a method for the routing of multimedia communication related signaling in a communication system. In the method a signaling message is received to a first network node. The signaling message provides an identity associated with a user. A hash key is computed from the identity. The hash key is matched to a number of key ranges, each key range being associated with a network node. A second network node is determined by detecting that said hash key belongs to the key range of the second network node. A signaling message is provided to the second network node. Subscriber data associated with the identity is obtained in from the second network node. The signaling message is processed in the second network node based on information in the subscriber data.
