Handover information sent over a public wide area network (e.g. internet)

摘要

A basestation (50) in a mobile communications network is connected to the core network of the mobile communications network over a public wide area network. In the event of a handover between the basestation and another of the network nodes of the PLMW (120), handover information (130, 132, 134) is sent between the basestation and the core network over the public wide area network, for example embedded in a SIP message or in a UMA message.
