Abstract

Abstract A radio telecommunication apparatus to be used in a radio telecommunication system wherein one or more base units broadcast radio signals over a plurality of radio channels. The apparatus detects the availability of one or more radio channels and provides an indication representing operability of the apparatus in response to a change of the detected availability. The apparatus also provides an indication to a user in response to his request input or a call origination operation. Furthermore, the apparatus may provide an indication of which system is serving the apparatus in response to a received system identification signal.

Claim 2
Dependent Claim 118 words
A radio telecommunication apparatus for use in a radio telecommunication system, wherein one or more base units broadcast radio signals over a plurality of radio channels, comprising: selecting means for selecting at least one of the plurality of radio channels for reception of the radio signals; receiving means responsive to said selecting means for receiving radio signals transmitted from said base station over the at least one selected radio channel; characterised by: detecting means coupled to said receiving means for detecting the availability of the selected radio channel; and audible indication means coupled to said detecting means for providing an indication to a user in response to a change of the detected availability of the selected radio channel.
Claim 3
Dependent Claim 27 words
The apparatus of claim 1 wherein said audible indication means provides an indication to a user when the selected radio channel changes to a state of availability.
Claim 4
Dependent Claim 28 words

Claim 5
Dependent Claim 20 words
The apparatus of claim 1 wherein said detecting means detects whether a synchronization signal is obtained from the received signals.
Claim 6
Dependent Claim 23 words
The apparatus of claim 1 wherein said detecting means detects whether the electric field intensity of the received signals exceeds a predetermined value.
Claim 7
Dependent Claim 20 words
