Dependent Claim
47 words
A wireless base station according to claim 1 wherein the means for transmitting an adapted signal comprises means for providing a signal capable of providing information on the quality of the first part of the communication channel between the wireless base station and the fixed base station.
Claim 8
Dependent Claim
24 words
A wireless base station according to claim 1 wherein the means for transmitting comprises means for providing a signal representative of a predetermined message.
Claim 9
Dependent Claim
20 words
A wireless base station according to claim 7 wherein the signal representative of a predetermined message is a mute signal.
Claim 10
Dependent Claim
38 words
A wireless base station according to claim 1 wherein the means for transmitting an adapted signal comprises means for transmitting an indication to the radio handset that the radio handset should pause for a period before initiating handover.
Claim 11
Dependent Claim
30 words
A wireless base station according to claim 9 wherein the radio handset is adapted to pause before initiating handover in response to the indication transmitted from the wireless base station.
Claim 12
Dependent Claim
60 words
A wireless base station according to claim 1 wherein signals received by the wireless base station comprise error detection information for enabling a corrupt signal to be detected and wherein the means for transmitting comprises means for replacing the error detection information such that the error detection information indicates that the signal transmitted to the radio handset is not corrupt.
Claim 13
Dependent Claim
115 words
A cellular radio telephone system comprising a radio handset and a wireless base station for establishing a communication channel between a fixed base station and the radio handset, the communication channel comprising a first part between the fixed base station and the wireless base station and a second part between the wireless base station and the radio handset, the wireless base station comprising means responsive to an indication that the first part of the communication channel between the wireless base station and the fixed base station is corrupt for transmitting an adapted signal to the radio handset to maintain the second part of the communication channel between the wireless base station and the radio handset.
Claim 14
Dependent Claim
115 words
A cellular radio telephone system comprising a radio handset and a wireless base station for establishing a communication channel between a fixed base station and the radio handset, the communication channel comprising a first part between the fixed base station and the wireless base station and a second part between the wireless base station and the radio handset, the wireless base station comprising means responsive to an indication that the first part of the communication channel between the wireless base station and the fixed base station is corrupt for transmitting an adapted signal to the radio handset to maintain the second part of the communication channel between the wireless base station and the radio handset.
Claim 15
Independent Claim
151 words
A method of communicating between a wireless base station and a radio handset in a cellular radio telephone system in which a wireless base station is involved in establishing a communication channel between a fixed base station and a radio handset, the communication channel comprising a first part between the fixed base station and the wireless base station and a second part between the wireless base station and the radio handset, the method comprising steps of: determining that the first part of the communication channel between the wireless base station and the fixed base station is corrupt; and transmitting an adapted signal to the radio handset in response to an indication that the first part of the communication channel between the wireless base station and the fixed base station is corrupt in order to maintain the second part of the communication channel between the wireless base station and the radio handset.
