Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
166 words
A method for paying for the use of a cellular telephone, said method comprising steps of: connecting a cellular telephone to a telephone network when one or more encrypted authentication signals are the same; answering the connected cellular telephone call from a cellular telephone user to establish two-way communication; formulating a response for transmission to the user requesting the input of data, that includes an access code number uniquely identifying the cellular telephone to be recharged with funds or units; processing at a central location the input data, upon receipt, to check the authenticity of the call; determining at a central location a new access code for each request for additional payment that uniquely identifies the cellular telephone; updating the user's file at a central location and in the cellular telephone to reflect the fact that the identified cellular telephone is to be recharged with additional funds or units; and transmitting the amount of funds or units requested by the caller and the new access code.
Claim 2
Independent Claim
166 words
A method for paying for the use of a cellular telephone, said method comprising steps of: connecting a cellular telephone to a telephone network when one or more encrypted authentication signals are the same; answering the connected cellular telephone call from a cellular telephone user to establish two-way communication; formulating a response for transmission to the user requesting the input of data, that includes an access code number uniquely identifying the cellular telephone to be recharged with funds or units; processing at a central location the input data, upon receipt, to check the authenticity of the call; determining at a central location a new access code for each request for additional payment that uniquely identifies the cellular telephone; updating the user's file at a central location and in the cellular telephone to reflect the fact that the identified cellular telephone is to be recharged with additional funds or units; and transmitting the amount of funds or units requested by the caller and the new access code.
Claim 3
Dependent Claim
122 words
The method claimed in claim 1, wherein the cellular telephone is equipped with ascending and descending registers, which further include the steps of: formulating a request for the transmission to the caller requesting the input of the numeric contents of the ascending and descending registers of the identified cellular telephone; summing the contents of the ascending and descending registers and comparing this total with the total of these registers held in computer memory as a result of the previous recharging of the identified cellular telephone; upon the detection of the equality there between, preceding with the determination with the next access code; and said updating step including storing in the computer memory the contents of the ascending and descending registers as entered.
Claim 4
Dependent Claim
34 words
The method claimed in claim 2, wherein the computer memory also stores the current credit balance of each cellular telephone user's account and the dollar amount to which the cellular telephone may be recharged.
Claim 5
Dependent Claim
55 words
The method claimed in claim 3, further including the steps of: prior to proceeding to the determination of the next access code, checking the credit balance of the user's account to determine if the user has sufficient funds on deposit or sufficient credit to cover the amount of funds or units requested by the user.
Claim 6
Dependent Claim
89 words
The method claimed in claim 2, which further includes the steps of: in the event an inequality is detected between the sum of registers n the cellular telephone and the sum of registers stored in computer memory, checking to determine if the ascending register of the identified cellular telephone overflowed since its previous recharging by comparing the entered cellular telephone sum of registers total with the stored registers computer readings minus ascending register size and if equality is then detected, proceeding to the determining a new access code step.
Claim 7
Dependent Claim
133 words
The method claimed in claim 2, wherein the access code number issued on the previous occasion when the identified cellular telephone sought to be recharged is stored in computer memory, which further includes in the event inequality is detected between the sum of the registers in the cellular telephone and in the sum of the registers stored in the computer memory the steps of: checking to determine if the identified cellular telephone was actually recharged on that previous occasion on the basis of the stored cellular telephone and stored register readings and the amount of units or funds by which the identified cellular telephone may be recharged, and if not; retrieving the stored access code from memory for transmission to the cellular telephone without executing the next determining a new access code step.
Claim 8
Dependent Claim
113 words
The method claimed in claim 1, wherein the cellular telephone is equipped with one or more registers, which further include the steps of: formulating a request for the transmission to the caller requesting the input of the numeric contents of the registers of the identified cellular telephone; summing the contents of the registers and comparing this total with the total of these registers held in computer memory as a result of the previous recharging of the identified cellular telephone; upon the detection of the equality there between, preceding with the determination with the next access code; and said updating step including storing in the computer memory the contents of the registers as entered.
Claim 9
Dependent Claim
31 words
The method claimed in claim 1, wherein the step of determining a new access code further includes the steps of: using a random number generator for determining a new access code.
Claim 10
Independent Claim
128 words
A system for paying for the usage of a cellular telephone, said system comprising: means for connecting a cellular telephone to a telephone network when one or more encrypted authentication signals are equal; means located at a site remote from the cellular telephone for generating one or more challenge signals; means located in a cellular telephone for generating a response to the challenge signals; means for recomputing a new challenge signal upon completion of generating a response to the challenge signal; means for comparing the challenge signals to the responses to determine the identity and authenticity of the cellular telephone; means for transferring funds or units to the cellular telephone; and means located at a site remote from the cellular telephone for recording the transferred funds or units.
Claim 11
Independent Claim
128 words
A system for paying for the usage of a cellular telephone, said system comprising: means for connecting a cellular telephone to a telephone network when one or more encrypted authentication signals are equal; means located at a site remote from the cellular telephone for generating one or more challenge signals; means located in a cellular telephone for generating a response to the challenge signals; means for recomputing a new challenge signal upon completion of generating a response to the challenge signal; means for comparing the challenge signals to the responses to determine the identity and authenticity of the cellular telephone; means for transferring funds or units to the cellular telephone; and means located at a site remote from the cellular telephone for recording the transferred funds or units.
Claim 12
Dependent Claim
147 words
The system claimed in claim 9, wherein said means for connecting comprises: means contained within the cellular telephone for generating an encrypted number that specifies to the cellular telephone containing said means; means coupled to the base station for receiving the encrypted number generated by said means; means contained within the base station for generating an encrypted number that is unique to the cellular telephone communicating with the base station; and means contained within the base station for comparing the encrypted number generated by said means contained within the cellular telephone with the encrypted number generated by said means contained within the base station, so that if the encrypted number generated by said means contained within the cellular telephone is the same as the encrypted number generated by said means contained within the base station, the cellular telephone is connected to the network to complete a call.
