Mobile unit supervisory control sequencer and method
First Claim
1. A mobile telephone unit comprising:
- first storing means for storing aan address signal representing a telephone system subscriber;
means for displaying the stored address signal;
a manually depressable call switch for generating a call initiation signal;
second stroring means for storing said generated call initiation signal;
means for selecting one of a predetermined plurality of communication channels for broadcast of a call-up signal;
means for generating a call enabling signal in response to the selection of said one communication channel;
means for broadcasting a call-up signal including said stored address signal over the selected one of the plurality of communication channels in response to the simultaneous presence of both said call initiation signal generated through the manual depression of said call switch and said call enabling signal generated in response to the selection of said one channel;
means for receiving a response signal acknowledging said call-up signal for automatically indicating receipt of said response signal; and
means including a handset removably cooperable with a hook-switch independent of said manually depressable call switch for establishing two-way voice communication over a two-way communication channel in response to removal of said handset from cooperating relationship with said hook-switch, whereby a call may be initiated and acknowledged without removing the handset from the hook-switch.

Abstract
A mobile communication unit providing simplified calling procedures and thus an increase in the effective use of communication channels. An address signal representing a telephone system subscriber may be entered into a storage register in the mobile unit and the address signal in the register is displayed. A manually depressable call switch is depressed to generate a call initiation signal and a call-up signal including the stored and displayed address signal is broadcast in response to the generation of said call initiation signal through the manual depression of said call switch. A response signal acknowledging said call-up signal is received and receipt of said response signal is automatically indicated. Two-way voice communication is established over a two-way communication channel in response to removal of a handset from cooperating relationship with a hook-switch. The handset and hook-switch are independent of the manually depressable call switch so that a call may be initiated and acknowledged without removing the handset from the hook-switch. The mobile unit is operable to retain the last stored and displayed address signal for initiating the broadcast of subsequent call-up signals and the mobile unit includes means independent of said handset and hook-switch for clearing the stored address. Provision is made for storing a number of frequently called addresses and retrieving the addresses on demand of the mobile unit operator to further increase the ease of operation.

22. A method of initiating and establishing two-way communications between two telephone system subscribers from a mobile radio-telephone having a handset in removable cooperable engagement with a hook-switch, the method comprising the steps of:
-
storing an address signal representing a called telephone system subscriber; displaying the stored address signal for visual verification of the address signal; selecting one of a predetermined plurality of communication channels for broadcast of a call-up signal and generating a call enabling signal when said one channel has been selected; manually depressing a call switch to generate and store a call initiation signal while retaining the handset in engagement with the hook-switch broadcasting a call-up signal including the stored address signal in response to the generation of both the call initiation signal and the call enabling signal, receiving a response signal acknowledging the call-up signal; and
,automatically indicating receipt of the response signal to indicate the establishment of a communication link with the called telphone system subscriber with the handset in engagement with the hook-switch. - View Dependent Claims (23)

24. A mobile telephone unit for two-way communication over communications channels comprising:
-
means for generating a call-up signal including an address signal representing a called telephone system subscriber; and
,means for detecting the availability of a designated one of the communication channels for transmission of the call-up signal; means for generating and storing a call initiation signal; means for initiating the transmission of said call-up signal over the designated one of the communication channels in response to the simultaneous detection of the availability of the designated channel and the presence of the stored call initiation signal; said transmission initiating means being operable to initiate the transmission of said call-up signal repetitively, said transmission initiating means including means for effecting the transmission of said call-up signal a random time interval after initiation of transmission by said initiating means and introducing a random time delay between successive repeated transmissions of said call-up signal. - View Dependent Claims (25, 26, 27, 28)
