Abstract
Disclosed is a method for performing a handover in a communication system, comprising causing the MS to receive a ranging code including the information on a handover bandwidth request ranging code from a serving BS, the handover bandwidth request ranging code being used for the MS to get an uplink bandwidth required for the handover allocated by the serving BS in a contention-free scheme, and causing the MS to request the serving BS to allocate the uplink bandwidth for the handover by using the handover bandwidth request ranging code.
Claims8
A method for performing a handover by a mobile station (MS) in a communication system, comprising:
- causing the MS to receive a ranging code including information on a handover bandwidth request ranging code from a serving base station (BS), the handover bandwidth request ranging code being used for the MS to obtain an uplink bandwidth required for the handover allocated by the serving BS in a contention-free scheme;
- and
- causing the MS to request the serving BS to allocate the uplink bandwidth for the handover by using the handover bandwidth request ranging code.
A method for performing a handover by a serving base station (BS) in a communication system, comprising:
- enabling the serving BS to transmit ranging code information including the information on a handover bandwidth request ranging code to a mobile station(MS), the handover bandwidth request ranging code being used for the BS to allocate an uplink bandwidth required for the handover in a contention-free scheme.
A method of enabling a mobile station (MS) to request a base station (BS) to allocate a bandwidth in a communication system, comprising:
- causing the MS to receive a CDMA (Code Division Multiple Access) code information from the BS, the CDMA code information including a bandwidth allocation CDMA code for allocating a bandwidth;
- causing the MS to transmit a bandwidth request message containing the CDMA code to the BS;
- causing the MS to receive a bandwidth allocation message containing information on a bandwidth allocated by the BS according to the bandwidth request message;
- and
- causing the MS to transmit designated information through the bandwidth to the BS.
A method for enabling a base station (BS) to allocate a bandwidth in a communication system, comprising the steps of:
- causing the BS to transmit CDMA (Code Division Multiple Access) information including a CDMA code for allocating the bandwidth to a mobile station (MS);
- causing the BS to receive a bandwidth request message containing a CDMA code for requesting allocation of the bandwidth from the MS;
- and
- causing the BS to allocate the bandwidth according to the bandwidth request message and then to transmit information on the bandwidth to the MS.
