Abstract

A keyless portable cellular phone system is provided, wherein matched sets of algorithmically generated communication units are generated, each communication unit pair defining a discrete time increment of authorized communication. One set is stored on a system server (i.e. a service provider), and the pre-paid set is available for use within a keyless portable cellular phone. The phone, normally non-activated, automatically contacts the system server upon selective activation by the user, to initiate a call (outgoing or incoming). A voice recognition system allows the user to place calls and/or receive calls. During a call, the keyless portable cellular phone periodically sends the sequential discrete airtime communication units, having unique identifiers (i.e. encryption), whereby the system server allows pre-paid authorized access to time increments of system services, such as communication, based upon the receipt of the matching, uniquely identified, sequential discrete airtime communication units. The phone typically has either an internal energy supply and storage for pre-paid communication units, or a removable airtime cartridge, typically containing an energy supply and either the ability to store or to generate a set of pre-paid single use airtime communication units.

Dependent claims

A communication system, comprising:

a system server, said system server having a plurality of algorithmically generated sequential single use server communication units, each of said plurality of algorithmically generated single use sequential server communication units defining a discrete time increment of authorized communication;
and
a keyless portable wireless phone having wireless phone circuitry, an energy storage, and an airtime cartridge, said airtime cartridge having an airtime cartridge identifier, and a plurality of algorithmically generated sequential pre-paid single use airtime communication units, each of said plurality of algorithmically generated pre-paid single use communication units matching corresponding of said each of said plurality of algorithmically generated sequential server communication units at said system server, each of said plurality of algorithmically generated pre-paid single use airtime communication units defining a discrete time increment of authorized communication, each of said plurality of algorithmically generated pre-paid single use communication units having a unique identifier;
whereby sequential transmission of each of said algorithmically generated pre-paid single use airtime communication units having said unique identifiers from said keyless portable wireless phone to said system server is matched to said corresponding of said each of said plurality of algorithmically generated sequential single use server communication units at said system server, in which said system server allocates said defined discrete time increment of authorized communication for said keyless portable wireless phone based upon said matching of each of said corresponding algorithmically generated single use server communication units and said algorithmically generated pre-paid single use airtime communication units.

A process, comprising the steps of:

providing an algorithm;
generating a plurality of sequential single use server communication units using said algorithm, each of said plurality of algorithmically generated single use sequential server communication units defining a discrete time increment of authorized communication;
supplying said plurality of sequential single use server communication units to a system server;
generating a plurality of sequential single use airtime communication units having unique identifiers using said algorithm, each of said plurality of algorithmically generated sequential single use airtime communication units defining a discrete time increment of authorized communication and matching corresponding of each of said plurality of algorithmically generated single use sequential server communication units;
providing a keyless portable wireless phone having wireless phone circuitry, energy storage, and an airtime cartridge, said airtime cartridge having an airtime cartridge identifier;
establishing said plurality of sequential single use airtime communication units having said unique identifiers to said airtime cartridge within said keyless portable wireless phone on a pre-paid basis;
authorizing access to said system server based upon a receipt of transmitted airtime cartridge identifier from said keyless portable wireless phone;
and authorizing said discrete time increments of authorized communication for said keyless portable wireless phone, based upon a receipt of one or more sequentially transmitted sequential single use airtime communication units having unique identifiers, using said algorithm to retrieve each of said sequential single use airtime communication units from each of said unique identifiers, and matching each of said transmitted sequential single use airtime communication units with each of said corresponding sequential single use server communication units at said system server.
