MOBILE WIRELESS REMOTE COMMUNICATION SYSTEM USING ENHANCED HARD HAND-OVER

摘要

PROBLEM TO BE SOLVED: To provide a mobile wireless remote communication system such as a generic mobile phone system or a blanket mobile communication. SOLUTION: A TRNC 54 in a UMTS directly transmits a takeover instruction signal to an SRNC 52 via an Iur link 50 to realize takeover of control of a mobile body from the RNC 52 handling the mobile body to an object RNC 54. Even when a link is present in advance or not present, the TRNC may transmit a request and a protocol to set the link stated above. A core network no longer takes participation in the takeover and a considerable time can be saved.
