Abstract
A system and method for supplemental channel (SCH) assignment control in a Code Division Multiple Access (CDMA) mobile communication system. Upon request of a Mobile Station (MS) for a SCH, a maximum available data rate is determined which is less than a predetermined data threshold. The MS is notified of the determined maximum data rate. Thus, the SCH is assigned to the MS.

A method of assigning a call to a mobile station (MS) on a reverse supplemental channel (R-SCH) in a Code Division Multiple Access (CDMA) mobile communication system where a base station (BS) having a cell divided into a plurality of sectors and a plurality of MSs is located in each sector, the method comprising the steps of:
- comparing a total load of a sector in which the MS is located to a predetermined data threshold, upon request of the MS for an R-SCH;
- determining a maximum data rate available to the R-SCH which is less than the data threshold if the total load of the sector is less than the data threshold;
- and
- notifying the MS of the determined maximum data rate.
A method of assigning a call to a mobile station (MS) on a reverse supplemental channel (R-SCH) in a CDMA Code Division Multiple Access (CDMA) mobile communication system where a base station (BS) having a cell divided into a plurality of sectors and a plurality of MSs is located in each of the sectors, the method comprising the steps of:
- determining a maximum data rate available to the R-SCH in each one of the sectors and base transceiver stations (BTSs) communicating with the MS, upon request of the MS for the R-SCH at handoff;
- selecting the lowest of the maximum data rates from the sectors or BTSs;
- and
- notifying the MS of the selected data rate.
A system for assigning a call on a reverse supplemental channel in a communication system, said system comprising:
- a Mobile Station (MS), a Base Station (BS) having a cell divided into a plurality of sectors, a plurality of MSs disposed within each of said sectors, a Base Transceiver Stations (BTs) and a Base Station Controller;
- said BS is adapted to perform the following operations:
- compare a total load of a sector in which the MS is located to a predetermined data threshold, upon request of the MS for an R-SCH;
- determine a maximum data rate available to the R-SCH which is less than the data threshold if the total load of the sector is less than the data threshold;
- and
- notify the MS of the determined maximum data rate.
