Base station repeater

摘要

A cellular telecommunications network base station repeater for a mobile terminal in a network having a power control function causes, during an active communication session, mobile terminal uplink transmit power to decrease in response to an increase in signal strength of the received uplink signal. The gain of the repeater is increased in response to an increase in the uplink signal received at the repeater above a threshold, and subsequently decreasing the gain until the measured power in the received uplink signal exceeds the threshold. Due to the power control function, increasing the gain causes the transmit power of the mobile terminal, and hence the uplink signal received at the repeater, to decrease. Decreasing the gain causes the transmit power, and hence the received uplink signal, to increase. The threshold not being exceeded is indicative of the communication no longer being active, and the repeater will eventually deactivate.

1. A method of operating a cellular telecommunications network base station repeater for a mobile terminal in a cellular telecommunications network, which network has a power control function which during an active communication tends to cause the mobile terminal uplink transmit power to vary in response to a variation in signal strength of an uplink signal associated with that mobile terminal received at the network, the method comprising:
increasing gain of the repeater to cause the power control function to consequently instruct the mobile terminal to decrease the mobile terminal uplink transmit power, wherein the power control function instructs the mobile terminal individually to decrease the mobile terminal uplink transmit power of the mobile terminal independently of other mobile terminals in the cellular telecommunications network; and deactivating the repeater when a consequential decrease in the mobile terminal uplink power does not occur, wherein the deactivating of the repeater is automatically controlled at the repeater based on the mobile terminal uplink power monitored at the repeater not decreasing in response to increasing the gain of the repeater.
