Abstract: The invention describes a methods of enabling and performing location-based services especially geomessaging. The invention describes in detail a flexible combination of multicast Internet protocol addresses and area codes in order to generate geomessaging Internet protocol addresses. The geomessaging Internet protocol address enables to receive by means of a mobile communication device (300) according to the invention geomessages and to submit the geomessages by means of the geomessaging network entity (400) according to the invention. No signaling between the mobile communication device (300) and the network or any service provider within the network is necessary to specify the current location of the mobile communication device. Furthermore, there is no need for a geomessaging message provider to know which mobile communication device is currently located within a specific first area.

Abstract: The subject innovation relates to a method and system for selecting a core network to serve a mobile communication device. An exemplary method comprises receiving in the mobile communication device a first identifier from a shared radio access network being connected to multiple core networks. The exemplary method also comprises reading second identifiers of the multiple core networks from a data item stored in the mobile communication device upon receipt of the first identifier. The data item may comprise an allocation between the first identifier and the second identifiers. The exemplary method additionally comprises selecting the core network from a group of available core networks, the group being determined based upon the second identifiers.
