ABSTRACT:
A method in a communication network comprising a core network and a radio access network. At least one target cell is defined for at least one originating cell controlled by a first radio access network node. A request for a packet switched communication address of a second RAN node of the target cell is delivered to the second RAN node, and a response comprising the requested address is returned. The request and the response are transferred between the first radio access network node and the second radio access network node in information containers that are transparent to the core network. The received address information is stored in the first radio access network node for facilitating delivery of data packets between the originating cell and the target cell. Based on the stored cell-specific information, information may be exchanged between the nodes controlling the cells without congesting the essential core network elements and interfaces.
