METHOD FOR CONTROLLING ASYNCHRONOUS TRANSFER MODE SWITCH DUPLEXING WITHIN RADIO NETWORK CONTROLLER IN MOBILE COMMUNICATION SYSTEM

摘要

PURPOSE: A method for controlling ATM switch duplexing within an RNC(Radio Network Controller) in a mobile communication system is provided to duplex boards and links related to switch control within the RNC, thereby continuously supplying a service even during a switching process at the request of an operator or when an error is generated in hardware or software. CONSTITUTION: An application layer performs initialization(401), and a middleware duplexing processor decides a duplexing state(402), to determine an operation mode(403) and a standby mode(404). In the operation mode(403), if the standby mode(404) is restarted, an SCP requests initial dump data of the operation mode(405). The operation mode extracts connection information(406), informs the standby mode of the initial dump data(407), and stores connection information for backup in a duplexing data region(408). If a connection setup/cancellation request is received from an ACP(409), an application layer of the operation mode generates backup data(410), and transmits a connection setup/cancellation processing result to the ACP(411), then requests duplexing data backup to the standby mode(412). The standby mode stores the connection information for backup in the duplexing data region(413), and informs the operation mode of a backup processing result(414).
