Edge continued evolution, improved channel request method and system

摘要

The present invention is a method and system adapted to facilitate, between a mobile station (MS) and network, an indication of support for reduced time transmission interval (RTTI). The MS can provide a base station system (BSS) with an indication of its multislot capability within an access burst sent at the start of a contention based access. In another aspect, the MS can indicate support for a new Immediate Assignment message as the conventional Immediate Assignment message can only assign single timeslots. The present invention enables the Radio Access Network (RAN) to assign RTTI and more than one timeslot for GPRS/EDGE temporary block flows (TBFs) during an Access Grant Channel (AGCH) assignment. The method of the present invention can be implemented in a computer program product or distributed software adapted to be loaded into at least one or a plurality of memory locations and executed by at least one or a plurality of respective computer processors.

主权项

1. A method of reducing latency in a communications channel, comprising the steps of:
receiving, by a Radio Access Network (RAN), an indication in a packet channel request from a mobile station (MS) where the indication indicates that the MS supports a reduced time transmission interval (RTTI); including, by the RAN, an additional field in an Immediate Assignment message sent on an Access Grant Channel (AGCH); and, using, by the RAN in response to receiving the indication, the additional field to allocate to the MS more than one time slot (TS) on an uplink of the communications channel and one or more time slots on a downlink of the communications channel.
