Radio system and a subscriber terminal for a radio system
First Claim
1. A radio system providing a wireless local loop, said system comprising:
- a fixed network includingat least one exchange,at least one subscriber database, andbase stations, andsubscriber terminals communicating with the fixed network via a radio path, each subscriber terminal comprising a radio transceiver, a power source connected to an external power supply, a battery backup unit for the power source, means for measuring and providing test results concerning the signal level and signal quality on the radio path between a base station and the subscriber terminal, and means for measuring and providing test results concerning the charge level of the battery backup unit of the power source,each subscriber terminal being arranged to transmit the test results concerning at least one of the battery backup unit and the state of the power supply, to the fixed network, in a predetermined report message at predetermined intervals or in response to a predetermined test result,said at least one subscriber database of the radio network being arranged to maintain information about at least one of the charge level of the battery backup unit and the state of the external power supply, and abut the signal level and signal quality measured by each respective subscriber terminal.

Abstract
A radio system providing a wireless local loop, including a fixed network having at least one exchange, at least one subscriber database and base stations, and subscriber terminals communicating with the fixed network via a radio path. Each subscriber terminal includes a radio transceiver, a power source with a battery backup unit, a measurer for measuring the signal level and signal quality on the radio path between a base station and the subscriber terminal, and a measurer for measuring the charge level of the battery backup unit of the power source. The subscriber terminal transmits the test results concerning at least one of the battery backup unit and the power supply to the fixed network in a predetermined report message at predetermined intervals or in response to a predetermined test result. The at least one subscriber database of the radio network maintains information about at least one of the charge levels of the batteries and failures in the power supply of the subscriber terminals, and about the signal level and signal quality measured by the subscriber terminal.
