FIELD: method, system and network element for providing switching of addresses, if connection point at one end of connection is changed from first network node to second network node of cell communication network.
SUBSTANCE: information about address and information about at least one alternative address are transmitted in signaling message from first network node to second network node. Information about address or information about alternative address is selected in second network node and utilized for repeated establishing of connection to other end of connection. Therefore, new connection point is allowed to repeatedly set up connection to another end of connection, even if it is capable only to maintain communication with utilization of one of two addresses. Also, signaling messages, for example, messages, related to determining costs, legitimate interception and/or specialized software applications, received from various network nodes, can be correlated based on alternative addresses.
EFFECT: engineering of method and device for providing address switching or correlation function capability, which can be used to achieve reverse compatibility of addresses.
