A communications system is provided that uses a multiple access packet reservation type of protocol. The physical channels required for the packet transfers are specially allocated to one mobile station (referred to as a "VIP MS"). The VIP MS has the exclusive priority to use these allocated physical channels for packet data as needed. Consequently, the VIP MS always has the negotiated bandwidth available for the packet transfers. Furthermore, since the VIP MS is given the highest exclusive priority to access these physical channels ("VIP priority"), by allocating a reserved random access channel dedicated to the VIP MS (e.g., on one allocated uplink channel), the variable random access delays experienced by prior systems no longer exist Since the VIP MS is always scheduled first for transmissions on the downlink, and reserved access is provided for the VIP MS on the uplink, only a constant delay period for the uplink and downlink is involved. In other words, the VIP MS is guaranteed both a bandwidth for the packet transfers and a constant uplink and downlink delay.

[ What is claimed is:] [1.] A method for improving performance of a mobile communications system that uses at least a multiple access packet reservation protocol, comprising the steps of:allocating to a first mobile station an exclusive use of at least a first channel in said mobile communications system, for carrying downlink packet traffic;reserving for said first mobile station a second channel in said mobile communications system, for enabling uncontended access by uplink packet traffic;allocating to said first mobile station an exclusive use of at least a third channel in said mobile communications system, for carrying said uplink packet traffic; andwherein said first mobile station has exclusive use of said first and third channels and reserved access to said second channel during a same service interval.
