Channel allocation based on random plus planned processes
View Patent ↗Wireless communication traffic channels are allocated based on random plus planned processes. A request for a traffic channel is sent on a random traffic channel that is not a dedicated random access channel. A determination is made whether to allocate a traffic channel based on status of a subscriber that sere the traffic channel request, including determining base on temps of subscription of the subscriber. An implementation at a base station includes receiving the request on a traffic channel making the determination, and assigning either the traffic channel on which the request was received, or another channel. In a user terminal, the user terminal sends the request on a random traffic channel that it is not assigned to, and receives a traffic channel allocation, or an indication that no channel is available.
1. A method of operating a base station comprising:
receiving a random access request for a traffic channel of a plurality of traffic channels on a first random traffic channel of the plurality of traffic channels, the first random traffic channel not designated as a random access channel, the traffic channels to be selectively allocatable by the base station for communication with a user terminal;
determining whether a traffic channel of the plurality of traffic channels is available to allocate to the requestor based on an evaluation of factors, including evaluating a status of a subscriber from whom the request originates including subscription terms of the subscriber; and
communicating to the requestor whether a traffic channel of the plurality of traffic channels is available.
