Abstract

Cellular mobile telephone stations which are intended for installation and use in public transportation facilities, e.g., taxicabs, limousines, rental cars, etc. are equipped to support credit card billing of transient customers for use of the station services. The cellular pay stations, from the viewpoint of the serving cellular carrier facilities, are indistinguishable from standard cellular mobile stations.

The activities of the credit card stations are supported by an administrative processor which is connected to a standard telephone line of the public switched telephone network. The cellular stations and the administrative processor exchange data messages over a standard telephone connection. The data messages are used to establish operating options and parameters of the credit card mobile stations, compile records in the administrative processor to permit the assignment of billing responsibility to transient customers for use of the stations and connected facilities, and control the stations for administrative and commercial reasons.

Claims

1. A cellular mobile radio subscriber station equipped to support billing of individual accounts of transient customers for their use of the station and connected facilities comprising:

a cellular mobile radio subscriber set comprising;

means for generating call signalling signals, supervisory signals, and data message signals;

display means for displaying station status information and station operating instructions; and

a radio transceiver for communicating with a cellular mobile radio system and connected transmission, switching and terminal facilities of the public switched network;

said cellular station further comprising;

means for generating control signals and billing data defining said individual customer accounts;

register means for storing said billing data;

first control means responsive to said control signals for generating administrative call request signals;

means for storing the direct dialed calling number of an administrative processor,

second control means comprising means responsive to said administrative call request signals for originating, via said mobile radio system, direct dialed administrative calls to an administrative processor identified by said stored calling nuber; and

means for conducting bi-directional data administrative message communication exchanges between said mobile station and an administrative processor called via said mobile radio system; and

third control means responsive to certain of said administrative messages from said administrative processor for selectively enabling and disabling said station for the origination of calls by customers from said station.

2. A cellular mobile radio subscriber station in accordance with claim 1, wherein said means for generating control signals and billing data is a reader for cards having billing data indicia stored therein.

3. A cellular mobile radio subscriber station in accordance with claim 1, wherein said station control means further comprises:

means for screening said billing data for plausibility, means for selectively disabling said station for the origination of calls by the customer who proffered the card if the billing data is determined to be implausible and for generating signals for selectively enabling and disabling said second control means.

4. A cellular mobile radio subscriber station in accordance with claim 3 wherein:

if said billing data is determined to be implausible, said second control means is disabled until a card with plausible billing data is presented.

5. A cellular mobile radio subscriber station in accordance with claim 1 wherein:

said station, when enabled by said third control means, remains enabled until the occurrence of a significant control event.

6. A cellular mobile radio subscriber station in accordance with claim 1 wherein:

said station further comprises a source of dial tone;

means operative when said station is enabled to permit origination of calls for coupling said source of dial tone to the receiver of the station handset; and

means responsive to registration of the first digit of a called telephone number for removing said dial tone from said receiver.

7. A cellular mobile radio subscriber station in accordance with claim 1 wherein:

said station comprises means for monitoring the time between registration of call signaling digits and for generating a send signal for transmitting the registered digits to the serving cellular system when a standard interdigital time period is exceeded.

8. A cellular mobile radio subscriber station in accordance with claim 1 wherein:

said administrative messages exchanged between said stations and said administrative processor comprise formatted, coded data messages which each comprise a message type identifier and data.

9. A cellular mobile radio subscriber station in accordance with claim 1 wherein:

certain of said messages which are transmitted from said stations to said administrative processor comprise customer registration messages which contain, as data, said billing data defining customer accounts; and

others of said messages transmitted from said stations to said administrative processor comprise station registration messages which contain, as data, a summary of station activity between the preceding station registration message and the current registration message.

10. A cellular mobile radio subscriber station in accordance with claim 9 wherein said summary of station activity data comprises:

the telephone number of the last call placed under the immediately preceding customer registration, the number of calls placed by the station between the time of the immediately preceding customer registration message and the current registration message, and the total time duration of those calls.

11. A cellular mobile radio subscriber station in accordance with claim 9 wherein:

among the messages transmitted to said mobile stations are positive and negative acknowledgment messages to respectively indicate that a customer'"'"'s request to accept responsibility for billing of subsequent calls to and from the station has been accepted or denied.

12. A cellular mobile radio subscriber station in accordance with claim 11 wherein:

said station control means in response to a negative acknowledgment message terminates the registration call, activates appropriate displays to advise the customer of the rejection of credit, and rejects further efforts to register the customer'"'"'s card that was rejected by said negative acknowledgment message.

13. A cellular mobile radio subscriber station in accordance with claim 11 wherein:

said station control means in response to a positive acknowledgment message, terminates the registration call, activates appropriate displays which advise the customer to proceed with a call and "unlocks" the station to permit a customer to complete a call.

14. A cellular mobile radio subscriber station in accordance with claim 9 wherein:

said administrative processor from time to time initiates calls to a selected one of said stations for the purpose of bi-directional data communication with said station; and

said station comprises means for differentiating between calls from said administrative processor and calls from other stations and for initiating a "handshake" procedure between the station processor and the administrative processor if a call is found to be from an administrative processor.

15. A cellular mobile radio subscriber station in accordance with claim 1 wherein:

certain ones of the administrative messages transmitted from said administrative processor to said stations comprise station "set-up" messages which, as data, define station operating options and parameters; and

said stations in response to said set-up messages selectively enable and disable the station operating options in accordance with the received data, and establish station parameters of operation in accordance with the received data.

16. A cellular mobile radio subscriber station in accordance with claim 1 wherein:

said stations comprise a repertory dialer including a memory for storing calling numbers of telephone stations to be called by use of said repertory dialer; and

wherein further one'"'"'s data messages transmitted from said administrative processor comprise "load repertory dialer memory" messages which, as data, define telephone numbers; and

said stations, in response to said load messages, store the defined telephone numbers in the memory of said repertory dialer.
