20100009625 | Base Station Repeater - 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. | 01-14-2010 |

In addition to the conventional radio access network comprising macro base station, one or more additional access points are provided. The access point is connected to the network core by an IP transport broadband connection. The access point is configured to appear to the mobile terminal as a conventional base station—that is, it communicates with the mobile terminal using GSM or UMTS transport protocols and does not require any modification to a standard GSM or UMTS mobile terminal. A subscriber may be provided with a designated “home” access point to provide coverage in their premises.
