IMT-2000 MOBILITY FUNCTION TEST APPARATUS AND OPERATION METHOD |
摘要 |
PURPOSE: An IMT-2000 mobility function test apparatus and an operation method of the same are provided to verify a GSM Phase 2+ based mobility function of an ATM mobile switch without additionally constructing a physical apparatus like a mobile terminal and a base station and adapt a No.7 signal system which is a standardized and commercial command line signal method. CONSTITUTION: An IMT-2000 test apparatus(1) uses a TCP/IP and is connected with a LAN(Local Area Network)(4) and is used in any place in which a test apparatus is accessed using a personal computer. The IMT-2000 test apparatus(1) includes an ATM adaptation card and is connected with an ATM mobile switch(3) using an optical cable(2) and includes an NNI-M(Network-Network Interface with Mobility) of a wide band ISDN having a mobility. An IMT-2000 bearer process block(114) transmits and receives a mobility function related message with an IMT-2000 mobile call process(112) which processes a mobile terminal function in a test apparatus, namely, a transmission and receiving operation of a mobile call when performing a mobility function test and an IMT-2000 mobility management process(113) which processes a mobility management, and manages a base station operation, namely, a communication way. |
