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.
Claims20
A method of monitoring a control channel in a radio communications network comprising:
- a base station;
- a plurality of mobile stations;
- and
- first means for detecting access messages sent from mobile stations to the network;
- the method comprising:
- counting a first number of detected access messages;
- separately detecting access messages sent from said mobile stations by means of a receiver which is at least partly separate from the first means for detecting access messages;
- counting a second number of separately detected access messages;
- and
- comparing the first and second counted numbers.
Apparatus for use in a radio communications network comprising:
- a base station;
- a plurality of mobile stations;
- and
- first means for detecting access messages sent from mobile stations to the network;
- the apparatus comprising:
- means for counting a first number of detected access messages;
- a receiver, which is at least partly separate from the first means for detecting access messages, for separately detecting access messages sent from said mobile stations;
- means for counting a second number of separately detected access messages;
- and
- means for comparing the first and second counted numbers.
A method of monitoring a control channel in a radio communications network comprising:
- a base station;
- a plurality of mobile stations;
- means for detecting access requests sent from mobile stations to the network;
- and
- means for setting up calls in respect of granted access requests;
- the method comprising:
- counting a first number of granted access requests;
- separately detecting access requests sent from said mobile stations by means of a receiver which is at least partly separate from the means for detecting access requests and means for setting up calls;
- counting a second number of separately detected access requests;
- and
- comparing the first and second counted numbers.
