Sector selection for F-SCH

A CDMA wireless communication network providing a packet data call to at least one mobile terminal on a Forward Supplemental Channel (F-SCH), comprising:

• a Base Station Controller (BSC) controlling at least one Base Station (BS) defining a cell having a plurality of sectors;
• and
• a processor in said BSC operative to dynamically select a F-SCH serving sector for said packet data call, said processor performing the steps of:
• monitoring the radio channel conditions on a plurality of potential F-SCH serving sectors to obtain one or more radio channel condition measurements;
• applying infinite impulse response (IIR) filtering to said radio channel condition measurements to obtain filtered radio channel condition measurements;
• monitoring the load on said plurality of potential F-SCH serving sectors to obtain sector load measurements;
• and
• determining a new F-SCH serving sector based on said sector load measurements and said filtered radio channel condition measurements.

A method of dynamically selecting a Forward Supplemental Channel (F-SCH) serving sector for a packet data call to a mobile terminal in a CDMA wireless communication network, comprising:

• monitoring the radio channel conditions on a plurality of potential F-SCH serving sectors to obtain one or more radio channel condition measurements;
• applying infinite impulse response (IIR) filtering to said radio channel condition measurements to obtain filtered radio channel condition measurements;
• monitoring the load on said plurality of potential F-SCH serving sectors to obtain sector load measurements;
• for each said potential F-SCH serving sector, predicting the sector load for each possible F-SCH data rate, based on said filtered radio channel condition measurements and said sector load measurements;
• and
• selecting a new F-SCH serving sector based on said predicted sector loads and said data rates.

A method of dynamically selecting a serving sector for serving a mobile station on a Forward Supplemental Channel (F-SCH) from a plurality of sectors comprising:

• receiving radio condition information for each sector relative to the mobile station;
• applying infinite impulse response (IIR) filtering to said radio condition information to obtain filtered radio condition information;
• receiving sector loading information for each sector;
• identifying a best sector for serving the mobile station on the F-SCH based on the sector loading and filtered radio condition information;
• and
• selecting a new serving sector if the best sector is not the current serving sector.
