Method for implementing priority access in radio communication system

The invention discloses a method which can realize the priority access in a wireless communication system, which includes that: (1) the MAC address, the device ID, the access priority and the QoS property of users can be stored into a core network database, and authorized users can be identified by the MAC address and the device ID of the users; (2) when priority users are accessed network, the MAC address and the device ID of the priority users can be transmitted to the core network for the authorizing process; at the same time, the access priority and the QoS property of the priority users can be downloaded into a base station so as to determine the priority indication information of the priority users; at the same time, the base station can reflect the priority indication information onto the operation flow; (3) the base station can distribute slot resource for the authorized users with high priority indication information firstly when the base station is dispatched. The method solves the problem of priority access of emergency business.
