Abstract: The application relates to the problem that when an HeNB switches off (HeNB1-3) while connected via a proxy (PR) as mentioned by Release 11 of 3GPP TR 37.803 to a peer X2AP entity, the X2AP entity in the HeNB can not inform its peer (eNB1) that it is no longer reachable. The problem is solved in that when the proxy detects the disconnection of the SCTP connection (SCT-P1-3) between the HeNB and itself, it transmits an X2AP STOP message to the eNB (eNB1), whereby this message indicates the end of the SCTP connection (SCTP1-3) and identifies the HeNB.

Abstract: A method of transferring messages between base stations of a wireless telecommunications network, a proxy node, a method of transmitting messages from a base station, a base station and computer program products are disclosed. The method of transferring messages comprises the steps of: receiving an X2 Application Protocol message within an incoming X2 interface IP packet over an X2 interface from a source base station; extracting, from said X2 Application Protocol message, target base station identity information identifying a target base station; and routing the X2 Application Protocol message to said target base station, said X2 Application Protocol message being carried within an outgoing X2 interface IP packet having a target IP address derived from said target base station identity information. This approach uses a modified X2 Application Protocol message which includes the target base station identity information and which is wrapped within an X2 interface IP packet.

After it has received the configuration information, the node in the first network sends the identifying information to a plurality of access nodes in the first network via which mobile devices access the first network. The invention is particularly, but not exclusively, applicable where the first network is in accordance with LTE and the second one with UMTS, and the information includes RNC-ids for use in handover from the LTE to the UMTS network.

Abstract: A method for handover of a mobile terminal from a source node to a target node in a wireless telecommunications network, including the steps of: adding an indication in the preparation phase by which source node indicates to the target node if it is the one preferred or not. If a target node is not the one preferred but is still selected by the UE, it may indicate this to the source node as by a specific new message that comes earlier in the handover process than a message requesting the source node to release resources following successful handover to a new node. The source node can then in this case cancel handover preparations to other target nodes earlier and also start data forwarding where applicable earlier.
