Method, device, base station and system for direct uplink access in a mobile communications network

摘要

The invention relates to a method between a communications device (110) and a communications network, which communications network generally provides at least a direct cell access mechanism and an alternative cell access mechanism for the communications device for uplink access to the communications network. The method comprises determining by the communications network and indicating (230) to the communications device (110) whether the direct cell access mechanism can at a given time be provided. This being the case, the communications device can directly start sending user data (150) on a traffic channel. In a situation in which the direct cell access cannot be provided, it is indicated to the communications device that the alternative cell access mechanism should be used.
