interoperability with legacy radio access technologies for next-generation core network connectivity

摘要

Aspects of the invention relate to mechanisms for interoperability between legacy and new generation radio access technologies (rats) in a communication network. In some examples, a handover from a legacy access network to a new generation access network may be performed over a new generation core network. A handover request received on a new generation core network support node can include an identifier of a new generation target cell. The next-generation core network support node can identify another next-generation core network support node to which the handover can be routed based on the target cell identifier or can select the next-generation access network based on the target cell identifier. The next-generation core network support node can then communicate with the next-generation access network to complete the handover.
