Radio telecommunication apparatus with a plurality of system identification informations

Claim 2

Radio telecommunication apparatus for use in a radio telecommunication system, wherein the radio telecommunication system emcompasses a plurality of areas each having one or more base units which broadcast a system identification information over one or more radio channels within the area of the base units characterised in that the radio telecommunication apparatus comprises: receiving means for receiving a system identification information; storing means for storing one or more system identification informations; comparing means coupled to the receiving means and the storing means for comparing the received system identification information with each of one or more stored system identification informations, and enabling means responsive to the comparing means for enabling a communication with the base unit if the received system identification information coincides with one of one or more system identification informations.

Claim 3

The apparatus of claim 1 further comprising urging means responsive to the comparing means for urging a user to input an indicating information necessary for selecting either enabling the communication or disabling the communication if the received system identification information does not coincide with any one of one or more stored system identification informations and selecting means responsive to the indicating information for selecting either enabling the communication or disabling the communication.

Claim 4

The apparatus of claim 2 further comprising means responsive to the urging means for disabling the communication if the indicating information is not inputted with a predetermined period of time and means responsive to the urging means for enabling the communication if the indicating information is inputted within a predetermined period of time.

Claim 5

The apparatus of claim 1 wherein the comparing means further generates an output signal, the apparatus further comprising informing means, such as display means, responsive to the comparing means for informing a user of an information relating to the output signal if the received system identification information does not coincide with any one of one or more stored system identification informations.

Claim 6

The apparatus of claim 1 wherein the comparing means further generates an output signal, the apparatus further comprising voice synthesis means responsive to the comparing means for generating a synthesized voice corresponding to an information relating to the output signal.

Claim 7

The apparatus of claim 1 wherein the enabling means further generates an output signal, the apparatus further comprising informing means, such as display means, responsive to the enabling means for informing a user of an information relating to the output signal.

Claim 8

Radio telecommunication apparatus as claimed in claim 1 including disabling means responsive to the comparing means for disabling a communication with the base unit if the received system identification information does not coincide with any one of one or more stored system identification informations.

Claim 9

The apparatus of claim 1 including selecting means responsive to the comparing means for selecting either enabling a communication with the base unit or disabling the communication with the base unit.

Claim 10

The apparatus of claim 8 wherein the selecting means further generates an output signal, the apparatus further comprising informing means, such as display means, responsive to the selecting means for informing a user of an information relating to the output signal.

Claim 11

The apparatus of claim 8 wherein the selecting means further generates an output signal, the apparatus further comprising voice synthesis means responsive to the selecting means for generating a synthesized voice corresponding to an information.

Claim 12

Radio telecommunication apparatus for use in a radio telecommunication system, in which the apparatus selects a first channel from a base station associated with a radio system, detects a first system identification information over the first channel, the apparatus comprising: storing means for storing one or more system identification informations; first enabling means responsive to the storing means for enabling a communication with the base unit if the first system identification information coincides with one of one or more stored system identification informations; selecting means responsive to the first enabling means for selecting a second channel; receiving means responsive to the selecting means for receiving a second system identification information over the second channel; and second enabling means responsive to the receiving means and the stored means for enabling the communication with the base unit if the second system identification information coincides with one of one or more stored system identification informations.

Claim 13

Radio telecommunication apparatus for use in a radio telecommunication system, in which the apparatus selects a first channel from a base station associated with a radio system, detects a first system identification information over the first channel, the apparatus comprising: storing means for storing one or more system identification informations; first enabling means responsive to the storing means for enabling a communication with the base unit if the first system identification information coincides with one of one or more stored system identification informations; selecting means responsive to the first enabling means for selecting a second channel; receiving means responsive to the selecting means for receiving a second system identification information over the second channel; and second enabling means responsive to the receiving means and the stored means for enabling the communication with the base unit if the second system identification information coincides with one of one or more stored system identification informations.
