Abstract:
1. A method for a system comprising a communications device and a communications network, the method comprising: allocating, by the communications network, at least a direct cell access channel for the communications device for uplink access to the communications network, the direct cell access channel to permit the communications device to directly start sending user data on the direct cell access channel without requesting access resources when user data is available to send; providing an alternative uplink transmission mechanism for the communication device to send data to the communications network if the direct cell access channel cannot be provided; determining by the communications network conditions when the direct cell access channel is available for use at a given time; providing the communications device with a periodic availability message indication of the availability for use of the direct cell access channel during said conditions; and permitting reception of a transmission from the communications device without a channel request during said availability.
