First Claim
1. A Radio Network Controller, RNC, for assisting a handover of a data session from a first routing path, associated with a first access network and a first data port of said RNC, to an alternative routing path, associated with an alternative access network and a second data port of said RNC (said RNC being arranged to route data of said session over said first access network via said first data port, to a User Terminal, UT, by binding a session identifier identifying said data session to a first routing identifier, wherein said session identifier and said first routing identifier are defined in accordance with a standard protocol routing scheme of said first access network;
- said RNC being further arranged to carry out the following steps;
receiving a capability message uniquely identifying said UT according to a standard protocol routing scheme of said first access network and according to an alternative protocol routing scheme of said alternative access network, said capability message indicating that said UT is capable of establishing a data session through said alternative access network,creating an alternative routing identifier for said session complying with the protocol routing scheme of said alternative access network and associating said alternative routing identifier with said UT and said second port,associating at least said session identifier with said alternative routing identifier, andreceiving from the UT, for the purpose of a handover decision by the RNC, either a measurement report, said measurements are performed by an MRRM application provided in the UT, or radio resource management parameter received by the UT from an AP of the alternative radio access network;
orreceiving from the UT a handover decision taken by the MRRM application provided in the UT on the basis of radio resource management parameters received from an AP of the alternative radio access network, and/or MRRM parameters measured by the UT.

Abstract
The invention provides a method, to be used by a RNC (230), for assisting a handover of a data session from a first routing path, associated with a first access network, to an alternative routing path, associated with an alternative access network, wherein data is routed over said first access network to a UT (240) by binding a session identifier to a first routing identifier, wherein said session identifier and said first routing identifier are defined in accordance with a standard protocol routing scheme of said first access network, the method comprising the following steps: —receiving a capability message uniquely identifying said UT (240) according to a standard protocol routing scheme of said first access network and according to an alternative standard protocol routing scheme of said alternative access network, —creating an alternative routing identifier for said session complying with the standard protocol routing scheme of said alternative access network and associating said alternative routing identifier with said UT (240), and, —associating said session identifier with said alternative routing identifier. The invention also provides an RNC (230), a UT (240), software and software media for realising the invention.

14. A method to be used by a User Terminal, UT, for assisting a handover of a data session from a first routing path associated with a first radio access network and a first data port of said UT, to an alternative routing path associated with an alternative radio access network and a second data port of said UT, said data session uniquely identified by a session identifier at said UT, said first data port associated with a first routing identifier according to a first radio access network standard protocol routing scheme, said second data port associated with an alternative routing identifier according to an alternative radio access network protocol routing scheme, wherein said UT is arranged to route data of said data session to a Radio Network Controller, RNC, over said first routing path by binding said session identifier to said first routing identifier, said first routing identifier associated with said UT at said RNC, said method comprising the following steps:
-
forming a capability message uniquely identifying said UT according to a standard protocol routing scheme of said first access network and according to a protocol routing scheme of said alternative radio access network, said message indicating that said UT is capable of establishing a data session through said alternative radio access network, sending said capability message to said RNC over said first or alternative routing path, and utilising an MRRM, Multi Radio Resource Management, application provided in the UT for retrieving radio resource management parameters from the alternative network, on which parameters handover decision is based. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
