Abstract
A data service providing method for use a communications system which has a forward traffic channel including a fundamental channel and a supplemental channel. The total transmission power of a base station is detected, and when it is complemental a reference transmission power data is transmitted on a forward link via a predetermined complemental channel. The complemental data is received from the forward link, and processed in a terminal.
Claims30
A method for providing complemental service in a CDMA communications system, comprising the steps of:
- detecting a total transmission power of currently used supplemental channels;
- comparing the total transmission power with a predetermined reference value;
- and
- determining supplemental channels available for the complemental service and inserting the supplemental channels as complemental channels when the total transmission power is smaller than the reference value.
A complemental service providing device in a CDMA communication system comprising:
- a power measurer for measuring the total transmission power of currently used supplemental channels;
- a comparator for comparing the total transmission power with a predetermined reference value;
- and
- a complemental channel inserter for determining supplemental channels available for the complemental service and inserting the supplemental channels as complemental channels when the total transmission power is smaller than the reference value.
A method for providing complemental service in a CDMA communication system comprising the steps of:
- detecting a total transmission power of currently used supplemental channels;
- comparing the total transmission power with a predetermined first reference value, determining supplemental channels available for the complemental service when the total transmission power is smaller than a first reference value, and inserting the supplemental channels as complemental channels;
- and
- comparing the total transmission power with a predetermined second reference value and removing the complemental channels when the total transmission power is larger than the second reference value.
A complemental service providing device in a CDMA communication system comprising:
- a power measurer for measuring the total transmission power of currently used supplemental channels;
- a first comparator for comparing the total transmission power with a predetermined first reference value;
- a complemental channel inserter for determining supplemental channels available for the complemental service and inserting the supplemental channels as complemental channels when the total transmission power is smaller than the first reference value;
- a second comparator for comparing the total transmission power with a predetermined second reference value;
- and
- a complemental channel remover for removing the complemental channels when the total transmission power is larger than the second reference value.
