Abstract

A temporary (temp) dedicated channel (DCH) is used to support communications. The temp-DCH channel is a channel that is assigned to a user having a set duration. After the duration expires, the channel is automatically released to the user. Embodiments of the invention relate to establishing the temp-DCH channel, determining the data rate and duration of the channel. Other embodiments relate to establishing back-to-back temp-DCH channels and the implementation details of these embodiments. Additionally, one embodiment relates to adding a start/stop function to the medium access controller which can be used in conjunction with temp-DCH as well as other applications.

Claims5

Dependent claims

A method for establishing a temporary dedicated channel in wireless communication system, the method comprising:

collecting packet data requiring wireless transmission;
based on an amount of the packet data, determining a transmission data rate for the data;
determining a duration for a dedicated channel based on the determined transmission data rate;
sending the collected packet data over the dedicated channel for the determined duration;
and
after the set duration expires, releasing the dedicated channel;
and
wherein at the expiration of the set duration, a second dedicated channel transmission occurs, the second dedicated channel transmission having a same transport format combination than the collected racket data transmission over the dedicated channel.
