Method, system and network nodes for transferring existing process information during a relocation procedure
First Claim
1. A method for transferring existing process information during a relocation procedure in a mobile telecommunication network comprising a core network node, a source radio access network node and a target radio access network node, the method comprising:
- starting a first process by sending a Radio Access Network Application Part Core Network Invoke Trace message from a core network node to a source radio access network node;
starting a second process by sending a Radio Access Network Application Part Location Reporting Control message from said core network node to said source radio access network node;
including a context of said first process and second process in at least one of a standard Radio Access Network Application Part and Radio Network Subsystem Application Part message in one of said core network node and said source radio access network node;
sending said at least one of said standard Radio Access Network Application Part and Radio Network Subsystem Application Part message from one of said core network node and said source radio access network node to a target radio access network node; and
handling said context in said target radio access network node as being received in said Radio Access Network Application Part Core Network Invoke Trace message and a Radio Access Network Application Part Location Reporting Control message.

Abstract
The invention describes a method, system and network nodes for transferring already started process information to a target radio access network node during a relocation procedure. Currently ongoing RANAP processes (location reporting and trace) are currently lost in the UTRAN at a successful SRNS Relocation. If they shall continue also after the relocation has been performed, their initiating RANAP procedures shall thus be reinitiated from the core network towards the target RNC after the Relocation Resource Allocation procedure has been successfully executed. In the invention the context of the two ongoing RANAP processes is transferred to the target RNC during SRNS relocation via existing RNSAP and RANAP messages. This will allow relocating of the processes on the target side without the extra Iu signaling to reinitiate them.
