ADVANCED GEOCASTING METHODS IN MOBILE COMMUNICATION NETWORKS, AND NETWORK NODES THEREFOR

摘要

The invention relates to a method performed by a network node (60) for providing a network service in a communication network (50) covering a geographical area for a plurality of mobile clients (40). The network node (60), hereinafter referred to as "proxy enabler" (60), receiving, from an application server (10), a request specifying a distribution target area. The Proxy enabler (60) queries a network node (30), hereinafter referred to as "geomessaging register" (30), for obtaining information about an appropriate service enabler (20) for handling a request associated with the specified distribution target area. The Proxy enabler (60) communicates with the appropriate service enabler (20) in order for the received request to be handled by said appropriate service enabler (20).
