Abstract
Abstract To test a cell in a cellular telecommunication network, a test mobile station is placed in the network near the cell and a server is connected to fixed communication devices of the network via a switched telephone network. The cell is confirmed to be operating correctly if a first call requested by the server to the test mobile station is set up and then cleared down by the test mobile station after first parameters transmitted by the server are received in the test mobile station, and thereafter if a second call requested by the test mobile station to the server via the cell under test is set up and then cleared down by the test mobile station after second parameters emitted by the test mobile station are received in the server. If this is not the case, the server reports incidents during the first or second call.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
181 words
A method of testing a cell in a cellular telecommunication network comprising fixed communication means serving a plurality of base transceiver stations respectively associated with cells of said network, a test mobile station being placed in said cellular telecommunication network, and a terminal means being connected to said fixed communication means, said method comprising the following steps: setting up a first call requested by said terminal means between said terminal means and said test mobile station, transmitting first parameters from said terminal means to said test mobile station if said first call is set up, clearing down said first call by said test mobile station if said first parameters are received in said test mobile station, setting up a second call requested by said test mobile station between said test mobile station and said terminal means via said cell after said first call is cleared down, emitting second parameters from said test mobile station to said terminal means if said second call is set up, and clearing down said second call if said second parameters are received in said terminal means.
Claim 2
Independent Claim
181 words
A method of testing a cell in a cellular telecommunication network comprising fixed communication means serving a plurality of base transceiver stations respectively associated with cells of said network, a test mobile station being placed in said cellular telecommunication network, and a terminal means being connected to said fixed communication means, said method comprising the following steps: setting up a first call requested by said terminal means between said terminal means and said test mobile station, transmitting first parameters from said terminal means to said test mobile station if said first call is set up, clearing down said first call by said test mobile station if said first parameters are received in said test mobile station, setting up a second call requested by said test mobile station between said test mobile station and said terminal means via said cell after said first call is cleared down, emitting second parameters from said test mobile station to said terminal means if said second call is set up, and clearing down said second call if said second parameters are received in said terminal means.
Claim 3
Dependent Claim
129 words
A method as claimed in claim 1, comprising a termination of at least one of said first call and second call by said terminal means in response to detection of at least one of the following incidents by said terminal means: failure to set up said first call, absence of clearing down of said first call after expiry of a first time-delay set after said step of transmitting said first parameters, failure to set up said second call after expiry of a second time-delay set after said step of clearing down said first call, absence of reception of said second parameters after expiry of a third time-delay set after said step of setting up said second call, and an error in said second parameters received in said terminal means.
Claim 4
Dependent Claim
57 words
A method as claimed in claim 2 wherein said error in said second parameters received by said terminal means is one of the following errors: incorrect number of digits representing one of said second parameters, erroneous predetermined digit at one of ends of one of said second parameters, and an erroneous parameter out of said second parameters.
Claim 5
Dependent Claim
55 words
A method as claimed in claim 2 wherein said terminal means executes said following steps cyclically to test said cell periodically, cumulatively counts occurrences of each of said following incidents thereby providing cumulative counts of incident occurrences and produces an alarm if one of said cumulative counts exceeds a predetermined number during a predetermined period.
Claim 6
Dependent Claim
71 words
A method as claimed in claim 1 comprising a clearing down of said first call by said test mobile station in response to any of the following events: absence of reception of said first parameters after expiry of a predetermined time-delay set by said test mobile station after said step of setting up said first call, and an error in one of said first parameters received in said test mobile station.
Claim 7
Dependent Claim
67 words
A method as claimed in claim 1 comprising a clearing down of said second call by said test mobile station in response to any of the following events: anticipated termination of said second call before said step of emitting said second parameters from said test mobile station, and expiry of a predetermined time-delay set by said test mobile station after said step of emitting said second parameters.
Claim 8
Dependent Claim
34 words
A method as claimed in claim 1 wherein at least one of said first parameters received correctly by said test mobile station is one of said second parameters emitted from said test mobile station.
Claim 9
Dependent Claim
74 words
A method as claimed in claim 1 wherein: said first parameters include at least one of following numbers: a number of said cell, a telephone number of said terminal means, a predetermined number identifying said terminal means, and a number identifying said first call, and said second parameters include at least one of following numbers: said number of said cell, said predetermined number identifying said terminal means, and said number identifying said first call.
Claim 10
Dependent Claim
50 words
A method as claimed in claim 1 wherein said first parameters are transmitted from said terminal means in the form of a sequence of digits in multifrequency code, and said second parameters are emitted from said test mobile station in the form of a sequence of digits in multifrequency code.
Claim 11
Dependent Claim
23 words
A method as claimed in claim 1 wherein said terminal means is connected via a switched telephone network to said fixed communication means.
Claim 12
Dependent Claim
27 words
A method as claimed in claim 1 wherein said terminal means executes said following steps cyclically for predetermined cells to be tested in said cellular telecommunication network.
