Description
REMOTE PROGRAMMING OF A RADIOTELEPHONE
Field of the Invention The present invention relates generally to the field of communications and particularly to cellular radiotelephones.
B~k~round of the Invention A radiotelephone has two unique numbers ~si~ned to it to identify that particular unit to the cellular carrier: a 15 telephone number and an Electronic Serial Number (ESN).
The radiotelephone must be programmed with the telephone number prior to use and can be reprogrammed later. The ESN is programmed when the unit is manufactured and typically stays with that particular unit throughout its service a~ life.
In order to assign a telephone number to the radiotelephone, the cellular radiotelephone carrier must know the radiotelephone's ESN. Since both the ESN and the telephone number are transmitted to the carrier when the 25 radiotelephone requests service, the radiotelephone will not be allowed access to the cellular system if the telephone number does not correspond to the correct ESN.
When the telephone number is programmed into the radiotelephone, the programmer tells the carrier the ESN and 30 the carrier responds with the new telephone number ?~ssi~ned to that ESN. This progr~mming process can cause problems.
If the programmer _isreads the ESN while informing the carrier or if the carrier copies it incorrectly, the radiotelephone will be denied access to the cellular system '~' 204~057 since the telephone number and ESN stored in the radiotelephone will not match the nllmbers in the carrier's data base. Additionally, access can be denied if the telephone number is programmed incorrectly. There is a resulting need 5 for a more reliable method of progr~mming a telephone number into a radiotelephone.
Sllmm~ry of the Invention The present invention enables the progr~mming of a radiotelephone from a remote location. The present invention is co,~ ised of a computer coupled to a data transceiving device such as a modem. The data transceiving device couples the computer to the telephone lines. The 15 radiotelephone to be programmed is coupled to an interface box that couples the radiotelephone to the telephone lines. The computer can communicate with the radiotelephone to be programmed through the telephone lines.
The present invention en~bles point of sale (POS) 20 progr~mming of the radiotelephone's telephone number, the system ID of the system in which the radiotelephone will be used, the unlock code, radio diagnostics, and other data. The computer, located at the carrier, interrogates either the POS
operator or the radiotelephone, depending on the information 25 needed. The POS operator responds using a telephone keypad while the radiotelephone responds automatically, acting like a peripheral of the computer. Using the present invention, the carrier's computer can read the radiotelephone's ESN and program the new telephone number automatically, 30 substantially reducing or eliminating errors made during manual progriqmming.

T)etailed Descril~tion of the P~efelled Emhodiment ao The present invention provides progr~mming of a radiotelephone from a remote location, such as the cellular carrier. By allowing the carrier to communicate with and program the radiotelephone over telephone lines or the cellular system, the chance for error is substantially reduced.
The point of sale (POS) progr~mming network, illustrated in Figure 1, is comprised of a computer (102) and modem (103) located at the cellular carrier's location. The co l~uler (102), hereinafter referred to as the base, has digitized voice comm~nll~ stored on its disk. These comm~n-l~ are sent over the telephone lines or cellular system at the appropriate time to request information from the POS
operator. The modem (103) couples the computer (102), via the telephone lines, to the progr~mmer's location. If the radiotelephone is progr?.mme-1 through the telephone line, the 20~0~7 telephone line is interfaced to the radiotelephone (104) being programmed by a POS interface box (100).
The POS interface box (100), illustrated in Figure 4, is comprised of a telephone interface (401), modem (402), and bus 6 interface (404) coupled to a microprocessor (403). The telephone interface (401) couples the outside telephone lines and a telephone (101) to the interface box (100). The telephone (101), having an integral keypad, is used to respond to certain requests for information by the base. The bus interface (404) is 10 a three-wire bus interface that couples the radiotelephone (104) being programmed to the interface box (100). For more information on the three-wire bus interface, see Kowalski, U.S. Patent No.4,654,655, Byrns U.S. Patent No. 4,369,516, and Wilson et al., U.S. Patent No. 4,616,314, all ~signed to 15 Motorola, Inc.
The progr~mming procedure followed by the base computer (102) is illustrated in Figures 3A and 3B. The base first checks for an incoming call (301) from a POS
progr~mming location. Once the call is established, the base ao requests a hardware identification number (302) from the POS
interface box. Each interface box has a unique ID number assigned to it to ~evellt unauthorized access to the base computer. If the interface box responds with an invalid ID
number (303), the progr~mming procedure ends without 25 allowing the radiotelephone to be programmed. The base then requests the customer's credit information (304). This can consist of a credit card or other financial information used for billing and verification of the customer's identity. The base next verifies the credit information with a credit validation 30 service and receives a validation code (306).
If the code is valid, the base prompts the POS operator for the security code and unlock code (306) that the customer wants ~ssigned and programmed into the radiotelephone.
The unlock code is a sequence of digits that must be input to 2045~57 allow operation of the radiotelephone if it has been previously locked. The security code i8 another sequence of digits that must be input by the cll~tomer whenever certain features of the radiotelephone, such as the unlock code, are changed.
The base next prompts the POS operator for the system irlsnt;fic~t;on number (307). The POS operator then responds with the system ID of the system in which the customer has chosen to operate. This system ID will be different for each carrier. For example, in the Chicago area, Ameritech Mobile Communications has a system ID of 20 and Cellular One has a system ID of 1.
If the system ID is a valid number (308), the base next reads the radiotelephone's Number A~sienment Module (NAM) data from the radiotelephone (309). The NAM data contains the system ID number, security codes, station class mark, and group ID mark in addition to the telephone number assigned to that particular radiotelephone. Once the base has the NAM data, it searches its data base for a new telephone number to be ~siene-l to the radiotelephone (310).
ao The base then reads the ESN from the radiotelephone (311).
The ESN is encrypted, using a conventional encryption routine, by the interface box before being sent over the telephone lines. This will l~revel,t unauthorized access to the customer's telephone number. The ESN read will now be associated with the new telephone nllmber. The NAM data is ~p~3~ted (312) with the new telephone number and programmed into the radiotelephone. To complete the progr~mmine, the base reads the NAM data again (313) to verify proper progr~mming.
The procedure followed by the interface box is illustrated in Figures 2A and 2B. The microprocessor initially checks for an offhook signal from the telephone (201) indicating that the POS operator is c~llin~ the base computer.
If the telephone is off hook, the procedure waits until a carrier - 6 - 204~0~7 (202) from the base is detected by the modem. Once the carrier is detected, contact with the base has been est~blished and the microprocessor waits for a message from the base.
An incoming message is checked to determine if it is one of the mess~ges allowed by the progr~mming procedure (203). Once it i8 determined that the meSsAge is within this range of messages, the procedure determines what the m9SS~Fe i8 and how to respond. If the base requests the interface box ID number (204), the interface box responds. If the base requests the customer's credit information (205), system ID (207), unlock code (207), security code (207), or to power up (206) or down (208) the radiotelephone, the POS
operator is prompted by voice comm~n~l over the telephone and can respond by either plmchin~ in the data on the telephone's keypad or pulling a credit card through a card reader. If the base requests radiotelephone data such as the NAM data or ESN, this request is passed on to the radiotelephone which then responds to the base.
In addition to progr~mming a radiotelephone, the ao present invention enables a technician at a remote site to troubleshoot a defective radiotelephone. The technician can determine the radiotelephone's condition by requesting the radiotelephone to respond with failure codes stored within the radiotelephone.
While the preferred embodiment of the present invention uses a telephone's integral keypad to respond to base comm~nds, an alternate embodiment uses the keypad integral to the radiotelephone being programmed. Another alternate embodiment, illustrated in Figure 5, uses an RF link (501 and 502) between the base colllp~lter (102) and the POS
interface box (100) instead of the telephone line link using the modem. Yet another alternate embodiment would allow progr~mming of the radiotelephone over the cellular system.
In this embodiment, illustrated in Figure 6, the POS interface ~0 45 0 ~ 7 box C;lC~ can be built into the radiotelephone (601). In another alternate embodiment, illustrated in Figure 7, the modem of the preferred embodiment is replaced by a DTMF
encoder/decoder (703) and the interface box (700) contains a 5 DTMF encoder/decoder in place of the modem allowing the radiotelephone (104) to be programmed using DTMF.
In sllmm~ry, the present invention provides remote progr~qmming of a radiotelephone. This reduces or elimin~tes the errors that commonly occur during manual 10 progr~mming. An additional benefit is that the present invention allows a customer to use the radiotelephone immediately after purchase instead of waiting to have the unit progr~mmed in a different location.
