Method and system for supplemental channel request messages in a wireless network
A method and system for obtaining reverse channel resources for a mobile device, the method filtering a closed loop correction power value; calculating a data rate utilizing the filtered closed loop correction power value; and sending a supplemental channel request message, including the calculated data rate, to a base station transceiver system.
1. A method for obtaining reverse channel resources for a mobile device comprising:
filtering a closed loop correction power value, the closed loop correction power value being a closed loop correction value for network conditions (TX_AGC_ADJ) for a code division multiple access network;
calculating a data rate utilizing the filtered closed loop correction power value, the calculating including calculating a power budget value (TX_EXTRA_GAIN) using the TX_AGC_ADJ value; and
sending a supplemental channel request message, including the calculated data rate, to a base station transceiver system.
2. The method of claim 1 , wherein the filtering utilizes a moving average filter.
3. The method of claim 2 , wherein the moving average filter uses a sample set of between 10 and 50 samples.
4. The method of claim 3 , wherein each sample is taken at an interval of 20 milliseconds.
5. The method of claim 1 , wherein the filtering uses an infinite impulse response filter.
6. The method of claim 5 , wherein the infinite impulse response filter calculates a new filtered value being equal to a filter length minus 1, times an output of the filter in a previous invocation of the filter, plus a new sample, all divided by the filter length.
7. The method of claim 1 , wherein the data rate is calculated for a reverse supplemental channel.
8. The method of claim 1 , wherein the mobile device utilizes a radio technology selected from a Global System for Mobile communications radio technology, a Code Division Multiple Access radio technology, a Universal Mobile Telecommunications System radio technology or a Long Term Evolution radio technology.
9. A mobile device configured to obtain reverse channel resources, the mobile device comprising:
a processor configured to:
filter a closed loop correction power value, the closed loop correction power value being a closed loop correction value for network conditions (TX_AGC_ADJ) for a code division multiple access network; and
calculate a data rate utilizing the filtered closed loop correction power value, the calculating including calculating a power budget value (TX_EXTRA_GAIN) using the TX_AGC_ADJ value; and
a communications subsystem configured to send a supplemental channel request message, including the calculated data rate, to a base station transceiver system.
10. The mobile device of claim 9 , wherein the processor utilizes a moving average filter.
11. The mobile device of claim 10 , wherein the moving averaged filter uses a sample set of between 10 and 50 samples.
12. The mobile device of claim 11 , wherein each sample is taken at an interval of 20 milliseconds.
13. The mobile device of claim 9 , wherein the processor uses an infinite impulse response filter.
14. The mobile device of claim 13 , wherein the infinite impulse response filter calculates a new filtered value being equal to a filter length minus 1, times an output of the filter in a previous invocation of the filter, plus a new sample, all divided by the filter length.
15. The mobile device of claim 9 , wherein the data rate is calculated for a reverse supplemental channel.
16. The mobile device of claim 9 , wherein the mobile device utilizes a radio technology selected from a Global System for Mobile communications radio technology, a Code Division Multiple Access radio technology, a Universal Mobile Telecommunications System radio technology or a Long Term Evolution radio technology.
