Open Architecture based ATM Switch Control Method in IMT-2000 Asynchronous RNC

摘要

PURPOSE: A method for controlling an ATM switch having an open-type structure within an RNC(Radio Network Controller) of a mobile communication system is provided to enable an additional function, and to add an interface function only with a GSMP(General Switch Management Protocol) of a control processor, without influencing an independent model function when replacing with a common ATM switch, thereby easily interworking with an open-type ATM switch. CONSTITUTION: An RNC sets a switch model identifier, and requests a connection setup/cancellation of an ATM switch control block(410). The ATM switch control block assigns necessary parameter values according to the switch model identifier(420), and distinguishes the switch model identifier. If the switch model identifier is a GSMP-based independent model, the control block directly transmits an IPC message used during inter-processor communication in a GSMP-based independent model ATM switch, and performs a switch control function(430). If connected to a GSMP complying switch, the block converts an IPC type into a message type(450), and transmits an additional message to a switching processor(460). A GSMP message is encapsulated(470). The additional message is supplied with a function, depending on whether the GSMP complying switch(480).
