Abstract
Abstract A method and apparatus for an authorized user of a cellular mobile radiotelephone to easily obtain data and performance evaluation of the telephone, such as the electronic serial number (ESN), the mobile telephone number (MID), and transmitted audio information that permits evaluation of the voice modulation performance of the telephone. By calling a dedicated telephone number, an authorized operator, such as a cellular agent, can contact a computer with voice response capability, which is associated with the electronic mobile exchange (cellular switch). The computer then transmits to the agent a voice prompt requesting a password. Upon correct entry of the password, the computer initiates a trunk trace of the incoming call. The trunk trace identifies the ESN and MID for the telephone used to make the call. The computer reports that data to the calling party, via the cellular network. Having supplied the telephone user or agent with the data, the computer then prompts the agent to record a voice sample on the system for subsequent re-transmittal to the telephne. By evaluating the re-transmitted voice sample, the agent can evaluate the voice modulation capability of the telephone.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
137 words
An apparatus for a cellular telephone system, comprising: call routing means, within a cellular switch, for directing a selected call placed by a cellular telephone and received by an input trunk of said cellular switch to an output trunk of said cellular switch, said output trunk being selectively attachable to a dedicated public switched telephone network subscriber line; data exchanging means, attached to said cellular switch, for transferring data to and from said cellular switch; and computing means, attached to said data exchanging means and to said dedicated public switched telephone network subscriber line, for initiating performance of one or more trunk traces by said switching in order to obtain one or more parameters of such cellular telephone and providing an output of said parameters to said cellular telephone, said output comprising one or more voice messages.
Claim 2
Independent Claim
137 words
An apparatus for a cellular telephone system, comprising: call routing means, within a cellular switch, for directing a selected call placed by a cellular telephone and received by an input trunk of said cellular switch to an output trunk of said cellular switch, said output trunk being selectively attachable to a dedicated public switched telephone network subscriber line; data exchanging means, attached to said cellular switch, for transferring data to and from said cellular switch; and computing means, attached to said data exchanging means and to said dedicated public switched telephone network subscriber line, for initiating performance of one or more trunk traces by said switching in order to obtain one or more parameters of such cellular telephone and providing an output of said parameters to said cellular telephone, said output comprising one or more voice messages.
Claim 3
Dependent Claim
88 words
An apparatus as recited in claim 1, wherein said computing means comprises: central processing means for managing functions of said computing means; first means, interposed between said central processing means and said dedicated public switched telephone network subscriber line, for, after establishment of a communications connection between said cellular telephone and said computing means, interactively obtaining information from said cellular telephone and providing an output of said parameters to said cellular telephone; and second means, attached to said central processing means, for obtaining said parameters from said switch.
Claim 4
Dependent Claim
30 words
An apparatus as recited in claim 1, wherein said data exchanging means comprises: means for serially transmitting data between said computing means and a switch port of said cellular switch.
Claim 5
Dependent Claim
22 words
An apparatus as recited in claim 1, wherein: said output trunk is arranged in direct outward dial, single member trunk group configuration.
Claim 6
Dependent Claim
16 words
The apparatus of claim 1, wherein the output signal is provided before said selected call terminates.
Claim 7
Dependent Claim
46 words
The apparatus of claim 1, wherein said computing means additionally comprises means responsive to transmission of an authorization code by the cellular telephone after the call is received, for selectively terminating the call in the event that the authorization code fails to match a predetermined number.
Claim 8
Dependent Claim
14 words
The apparatus of claim 6, wherein the authorization code comprises a personal identification number.
Claim 9
Dependent Claim
36 words
An apparatus as recited in claim 2, wherein: said information obtained from said cellular telephone comprises dual tone multi-frequency signals generated by said cellular telephone in response to depression of a keypad of said cellular telephone.
Claim 10
Dependent Claim
30 words
The apparatus of claim 8, which further includes means for selectively terminating said selected call in the event that said dual tone multi-frequency signals fail to match a predetermined signal.
Claim 11
Dependent Claim
14 words
An apparatus as recited in claim 2, wherein: said obtained information comprises audio signals.
Claim 12
Dependent Claim
32 words
An apparatus as recited in claim 10, wherein: said first means further comprises diagnostic testing means for recording said audio signals and subsequently retransmitting said recorded audio signals to said cellular telephone.
Claim 13
Independent Claim
163 words
A method to access data of a cellular telephone, comprising the steps of: receiving at an input trunk of a cellular switch a selected call, from said cellular telephone; routing said call to an output trunk of said switch, said output trunk being selectively attachable to a dedicated public switched telephone subscriber line, said line being attached to a computing means; interactively exchanging data between said computing means and said cellular telephone via said dedicated public switched telephone network subscriber line and a cellular network associated with said cellular switch; in response to said interactive exchanging of data, initiating performance by said cellular switch of one or more trunk traces of said selected call in order to determine one or more parameters of said cellular telephone; obtaining said parameters from said cellular switch; providing an output of said parameters to said cellular telephone, said output comprising one or more voice messages; and terminating said selected call after completion of said step of providing.
Claim 14
Independent Claim
163 words
A method to access data of a cellular telephone, comprising the steps of: receiving at an input trunk of a cellular switch a selected call, from said cellular telephone; routing said call to an output trunk of said switch, said output trunk being selectively attachable to a dedicated public switched telephone subscriber line, said line being attached to a computing means; interactively exchanging data between said computing means and said cellular telephone via said dedicated public switched telephone network subscriber line and a cellular network associated with said cellular switch; in response to said interactive exchanging of data, initiating performance by said cellular switch of one or more trunk traces of said selected call in order to determine one or more parameters of said cellular telephone; obtaining said parameters from said cellular switch; providing an output of said parameters to said cellular telephone, said output comprising one or more voice messages; and terminating said selected call after completion of said step of providing.
