Abstract: Information for different subscribers of a service with the same modulation and channel encoding method is transmitted by allocating radio resources in a wireless portable Internet system. Also, identifier information on the subscriber of a concurrently allocated radio resource is transmitted through common control information. Therefore, information for a plurality of subscribers coexists in a single radio resource block, and it can be easily transmitted. Since a subscriber station which has received downlink information can know to which radio resource block the information for the corresponding station is allocated through the subscriber identifier information transmitted as common control information, the subscriber station can access desired information by accessing a specific radio resource block to which information for the subscriber is allocated in the received frame.

Abstract: The present invention discloses a traffic control method of a wireless mobile communication which can reduce interference of users and provide various services, by efficiently managing frequency resources in the wireless mobile communication. A reserve access channel for channel reservation is based on a spreading code method, and controlled in slot units for a voice traffic and a data traffic. In order to minimize an error due to interference of the simultaneous users in one slot, a reserve channel permission probability function is obtained from the previous frame information. Accordingly, the reserve access channel controlling of the present invention improves a transmission delay property for various information sources of voice, data and real time traffic.
