Geo-location based dynamic uplink traffic channel allocation

摘要

Spectral efficiency is improved by assigning uplink channels according to expected receive signal levels at a serving base station. A first subscriber device detects a new call request indication, and then determines, as a function of its transmit power level and current location relative to the serving base station, an expected receive signal strength indication (RSSI) at its serving base station. Depending on whether it is determined that the expected RSSI is greater than or less than a RSSI threshold: one of (i) transmitting a call request to the serving base station requesting an assignment to a respective designated high-power or low-power channel for the new call and (ii) transmitting the new call on a respective pre-allocated high-power or low-power channel.

1. A method for improving spectral efficiency by assigning uplink channels according to expected receive signal levels at a serving base station providing wireless communications to a first subscriber device, the method comprising:
detecting, at the first subscriber device, a new call request indication; determining, as a function of the first subscriber device transmit power level and its current location relative to the serving base station, an expected receive signal strength indication (RSSI) of signals transmitted by the first subscriber device and received at the serving base station; if it is determined that the expected RSSI is greater than a pre-determined RSSI threshold:
one of (i) transmitting a call request to the serving base station requesting an assignment to a designated high-power channel for the new call and (ii) transmitting the new call on a pre-allocated high-power channel; and if it is determined that the expected RSSI is less than the pre-determined RSSI threshold:
one of (i) transmitting a call request to the serving base station requesting an assignment to a designated low-power channel for the new call and (ii) transmitting the new call on a pre-allocated low-power channel.
