Mobile unit supervisory control sequencer and method

摘要

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.
