Abstract: A method (300) and communication device (106) capable of streamlining call setups to a wireless mobile unit (102) may include a transceiver (520) and a controller (502). In various embodiments of the invention, the controller detects (302) a modified request for a communication resource, optionally monitors (304) a communication system loading parameter, and sends (406 or 408) an assignment for a larger than anticipated allocation of the communication resource upon detecting the modified request or when the system loading parameter falls below a predetermined threshold. The controller may also receive (410) via the larger than anticipated allocation of the communication resource both an anticipated initial data transmission and an initial user data transmission in a first data transmission from the mobile wireless unit.

Abstract: Various embodiments are described to address the need for an apparatus and method for communication resource acquisition that reduces the delay in acquiring resources without unduly wasting resources. In general, the described embodiments attempt to obtain desired resources in a just-in-time manner by using reasonably available information to characterize future packet transfers and calculate when resource acquisition should begin. The various embodiments involve calculating when to begin communication resource acquisition by considering a transfer-complete time, a ready-for-next-transfer time, an anticipated start time, and/or an anticipated acquisition time. In wireless communication systems (100), either the RAN (121) or the remote units (101) may be determining when to begin communication resource acquisition involving their air interface (111).
