Abstract
The need for reducing the time required for call setup in a wireless communication system (100) is addressed herein. A base station (BS 104) sends a channel assignment message to a mobile station (MS 102) and performs traffic channel initialization procedures with the MS. After completing the traffic channel initialization procedures, the BS sends a base station acknowledgment message to the MS and proceeds to transmit signaling to the MS without waiting to receive an MS acknowledgment in response to the base station acknowledgment message. Thus, the time normally taken to receive the MS acknowledgment is saved and call setup time reduced.
Claims18
A method for reducing call setup time comprising:
- sending a channel assignment message to a mobile station (MS);
- performing traffic channel initialization procedures with the MS;
- after completing traffic channel initialization procedures, sending a base station acknowledgment message to the MS;
- proceeding to transmit signaling to the MS without waiting to receive an MS acknowledgment in response to the base station acknowledgment message;
- after proceeding to transmit signaling to the MS receiving an MS acknowledgement in response to the base station acknowledgment message.
A base station comprising:
- wireless transceiver equipment (WTE) adapted to transmit and receive messaging to a mobile station (MS);
- a controller, communicatively coupled to the WTE,
- adapted to send, via the WTE, a channel assignment message to the MS,
- adapted to perform, via the WTE, traffic channel initialization procedures with the MS,
- adapted to send, via the WTE, a base station acknowledgment message to the MS, after completing traffic channel initialization procedures,
- adapted to proceed to transmit signaling, via the WTE, to the MS without waiting to receive an MS acknowledgment in response to the base station acknowledgment message, and
- adapted to receive, via the WTE, an MS acknowledgment in response to the base station acknowledgment message, after proceeding to transmit signaling to the MS.
