PROBLEM TO BE SOLVED: To reduce the size of information elements of a handover command message between generations. SOLUTION: The size of certain information elements in the UTRAN RRC "HANDOVER TO UTRAN COMMAND" message is made small, by reserving a subrange of IE parameter values for exclusive use by User Equipment which is performing an inter-Radio Access Technology (RAT) handover to a UTRAN. The lowest values of scrambling code number or S-RNTI number is reserved for initial assignment to a UE performing a handover from one system network to the UTRAN. Upon completion of the handover procedure, the UTRAN can assign another scrambling code number or S-RNTI number to that UE. Consequently, by significantly reducing the size of the IEs, additional parameters may also be used in the same message. COPYRIGHT: (C)2011,JPO&INPIT
