1. A mobile communications network, comprising:
- a PLMN, comprising a plurality of network nodes;
a core network anchor node; and
an access point, serving as a basestation in the mobile communications network, and being able to establish a tunneling connection over a public wide area network to the core network anchor node, such that, in the event of a handover between the access point and another of the network nodes of the PLMN, handover information is sent between the access point and the other of the network nodes of the PLMN over the public wide area network.

Abstract
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.

10. A core network node for use in a mobile communications network, wherein the core network node comprises an IMS-MSC, the IMS-MSC being adapted to establish a tunneling connection over a public wide area network to an access point, serving as a basestation in the mobile communications network, such that, in the event of a handover between the access point and another of the network nodes of the PLMN, handover information is sent between the access point and the IMS-MSC over the public wide area network.
- 11. A core network node for use in a mobile communications network, wherein the core network node comprises a SIP-MSC, the SIP-MSC being adapted to establish a tunneling connection over a public wide area network to an access point, serving as a basestation in the mobile communications network, such that, in the event of a handover between the access point and another of the network nodes of the PLMN, handover information is sent between the access point and the SIP-MSC over the public wide area network.

12. A core network node for use in a mobile communications network, wherein the core network node comprises a L-GANC, the L-GANC being adapted to establish a tunneling connection over a public wide area network to an access point, serving as a basestation in the mobile communications network, such that, in the event of a handover between the access point and another of the network nodes of the PLMN, handover information is sent between the access point and the L-GANC over the public wide area network.
- 13. A method of achieving a handover in mobile communications network, wherein the mobile communications network comprises a PLMN, having a plurality of network nodes, a core network anchor node, and an access point, serving as a basestation in the mobile communications network, wherein the basestation is connected over a public wide area network to the core network anchor node, the method comprising, in the event of a handover between the access point and another of the network nodes of the PLMN, sending handover information between the access point and the core network anchor node over the public wide area network.
