Combining differing transport technologies in a telecommunications system

For use in a telecommunications system having an application layer and a transport layer, the system comprising a first node which utilizes a first transport technology and a second node which utilizes a second transport technology, a method comprising:

• interworking the first transport technology and the second transport technology to facilitate establishment of a transport bearer between the first node and the second node without terminating or interworking with auplication control signaling in the application layer;
• executing at the application layer a radio network layer procedure to establish the transport bearer in a radio access network (RAN) of a wireless telecommunications method.

For use in a telecommunications system having an application layer and a transport layer, the system comprising a first node which utilizes a first transport technology and a second node which utilizes a second transport technology, a method comprising:

• interworking the first transport technology and the second transport technology to facilitate establishment of a transport bearer between the first node and the second node without terminating or interworking with application control signaling in the application layer;
• using q.aal2 signaling to interwork the first technology and the second technology.

For use in a telecommunications system having an apnlication layer and a transport layer, the system comprising a first node which utilizes a first transport technology and a second node which utilizes a second transport technology, wherein the first node is an IP-connected node, a method comprising:

• interworking the first transport technology and the second transport technology to facilitate establishment of a transport bearer between the first node and the second node without terminating or interworking with application control signaling in the application layer:
• the first node attempting to establish the transport bearer using application level signaling, but when unsuccessful the first node invoking an interworking function for establishing the transport bearer.

For use in a telecommunications system having an application layer and a transport layer, the system comprising a first node which utilizes a first transport technology and a second node which utilizes a second transport technology, wherein the first node is an IP-connected node, a method comprising:
