Abstract

There is described a method of detecting faults on an uplink control channel, such as an access channel. More specifically, a base station, or other network infrastructure component with a receiver for access requests, is provided with a separate receiver, which is adapted to detect and count access messages. The counted number of access messages is then compared with the number of access messages received by the first receiver. If the number of accesses received by the two receivers are significantly different, this may indicate a fault in the access channel.
