Abstract
A method for increasing the bandwidth within an air interface between a mobile station and a base station is disclosed. The method involves the seizing of multiple random access channels on the dedicated control channel between a single mobile station and the base station. Individual messages are then transmitted over each of the seized random access channels on a frame-by-frame basis. Up to six channels may be seized and utilized at any particular time.
Claims14
A method for transmitting messages over an air interface between a mobile station and a base station, comprising the steps of:
- seizing control of a plurality of random access channels between the mobile station and the base station;
- and
- simultaneously transmitting message frames from the mobile station to the base station on each of the plurality of random access channels.
A method for transmitting messages over an air interface between a mobile station and a base station, comprising the steps of:
- seizing control of at least a first and a second random access channel between the mobile station and the base station;
- monitoring on the first and second random access channels for a first indication of an ability to transmit a message frame from the mobile station to the base station;
- transmitting to the base station, a first message frame of a first message upon receipt of the first indication on the first random access channel;
- transmitting to the base station, a first message frame from a second message upon receipt of the first indication on the second random access channel, the first message frame from the second message transmitted in a frame slot different from the first message frame of the first message;
- and
- monitoring the first and the second random access channels for a second indication of receipt of the first message frames by the base station.
A method for increasing the uplink bandwidth on a dedicated control channel between a mobile station and a base station, comprising the steps of:
- seizing control of a plurality of random access channels on the dedicated control channel between the mobile station and the base station;
- monitoring the seized random access channels for a shared channel control flag indicating the ability to transmit a message on the random access channels;
- transmitting a message frame on a random access channel upon indication by the shared channel control flag of availability of the random access channel, wherein transmission of the message frame does not conflict with any other use of a time slot utilized by another of the seized random access channels;
- and
- monitoring the shared channel control flag for an indication of receipt of the transmitted message frame at the base station, wherein the step of monitoring for the indication comprises monitoring for the indication at least two frames after transmission of the message frame.
