Patent ID: 8804662

Claim:
A method for communication between wireless telecommunications networks of different technology types, said method comprising: setting up an air interface between a mobile terminal and a first node included in a network of a first technology type; setting up a signaling interface between the first node included in a network of a first technology type and a second node included in a network of a second different technology type, wherein the first node is an access services network node belonging to the network of the first technology type and the second node is a radio access network node belonging to the network of the second different technology type; providing messaging over the air interface related to handover of a mobile terminal from the network of the first technology type to the network of the second technology type; providing signaling messaging over the signaling interface in accordance with the second technology type, the signaling messaging being related to the handover; encapsulating the signaling messaging in a container for transmission over the signaling interface; associating an identifier from the messaging provided over the air interface with the container to indicate that the container encapsulates said signaling messaging; and when the identifier is detected at the first node, sending the container over the signaling interface to the second node; wherein the identifier is a special service flow identifier.
