Abstract

DC60 (06/01/41) The communication system was provided using a multi-access group reservation protocol. The physical channel required for group transfer was specially allocated to a single mobile station (referred to as the "VIP mobile station"). This VIP mobile station had a specific priority to use this allocated physical channel for the desired group transfer. As a result, the VIP mobile station always had available bandwidth for group transfer. Furthermore, because the VIP mobile station was assigned the highest priority in accessing these physical channels ("VIP priority"), by allocating reserved random access channels to such a VIP mobile station (e.g., uplink channel, etc.), the variable random access delays present in previous systems were eliminated. Since the VIP mobile station was designated first for downlink transmission, and reserved access was provided for the VIP mobile station, the uplink only had a fixed delay period for both uplink and downlink. In other words, the VIP mobile station was guaranteed both bandwidth and downlink access. For data packet transfer and fixed uplink and downlink delays, the communication system is provided using a reserved packet access protocol. The physical channel required for data packet transfer is specifically allocated to one mobile station (referred to as the "VIP mobile station"). This VIP mobile station has a specific priority to use this allocated physical channel for the data packets as needed. As a result, the VIP mobile station always has available bandwidth for data packet transfer. Furthermore, because the VIP mobile station is assigned the highest priority for accessing these physical channels ("VIP priority"), by allocating reserved random access channels to such a VIP mobile station (e.g., uplink channels, etc.), the variable random access delays present in previous systems are eliminated. Since the VIP mobile station is designated first for downlink transmission, and reserved access is provided for the VIP mobile station, the uplink only has a fixed delay period for both uplink and downlink. In other words, the VIP mobile station is guaranteed both bandwidth and downlink access. For data transfer and delays in fixed uplink and downlink systems.
