| 摘要 |
The present invention relates to a method, system and network element for providing an address transition if a connection point at one end of a connection is changed from a first network node to a second network node of a cellular network. An address information and at least one alternative address information are transmitted in a signaling message from said first network node to said second network node. One of said address information and said alternative address information is selected at the second network node and used for re-establishing said connection towards the other end of said connection. Thereby, the new point of connection is allowed to re-establish the connection towards the other end of the connection, even if it can only communicate using one of the two addresses. Furthermore, signaling messages, e.g. messages relating to charging, lawful interception, and/or customized applications, received from different network nodes can be correlated based on the alternative addresses. |
