Back~round of the Invention The use of cellular mobile telecommunications has undergone 10 substantial growth over the past few years. Due to a growing cellular customers base, cellular telephone service providers and cellular telephone service resellers are faced with serving an increased number of new subscribers demanding diversified cellular services. Also, a growing number of existing cellular subscribers tend to switch back and forth between various service providers depending on the marketing 15 and sales incentives offered by any one of such providers to newly signed-up cellular subscribers. The foregoing shifts and variations in customer - supplier and customer - reseller relationships require progldm~ g, as well as reprogramming, of the cellular telephone sets each time a customer subscriber desires a change.
Typically, cellular service providers require that any prospective 20 customer take the cellular telephone set, after purchasing it, to an authorized service center for programming so that such telephone set becomes an authoriæd cellular service user set. In the case of cellular service resellers, prospective subscribers are often asked to send the telephone set, after purchasing it, to an authorized agent for progr~mming In either case, the procedure is cumbersome and costly to the 25 customer, as well as to the provider or reseller, because delays are encountered prior to the start of service. Therefore, there exists a need for a method and an apparatus for programming wireless telephone sets in a manner that quickly, reliably and cost-effectively provides telephone service to new or existing customers.
Summary of the Invention The foregoing need is met in an illustrative embodiment wherein a method for programming a wireless telephone set comprises the steps of establishing a wireless bidirectional communication path between the wireless telephone set and a distant control center; activating the wireless telephone set to receive signals from the distant control center over the c~-mmllnication path; receiving, over the 35 communication path, a set of predetermined signals allocated to the wireless `- 204S800 telephone set; and storing in the wireless telephone set the received signals.
In accordance with another embodiment, a remotely programmable wireless telephone set comprises means for establishing a wireless bidirectionalvoice communication path between the wireless telephone set and a distant control S center, actuating means for selectively enabling the wireless telephone set to receive signals from the distant control center over the voice co~ ic~tion path; means for receiving, over the voice communication path, a set of predetermined signals allocated to the wireless telephone set; and means for storing in the wireless telephone set the received signals.
In accordance with a further embodiment, a method for remotely authorizing telecommunication service to a mobile telephone set from a control center comprises the steps of establishing a wireless bidirectional voice co""nllnication path between the control center and the mobile telephone set fortransmitting and receiving multifrequency tone signals therebetween over the voice 15 cnmmllnication path; receiving, at the control center, predetermined i(lentification indicia associated with the mobile telephone set; and tr~nsmitting from the control center, over the voice colllmunication path in response to the received identifi~tion indicia, service authorization tone signals allocated to the mobile telephone set.
Upon receipt, at the mobile telephone set, of the service authorization tone signals, 20 digital representations of such tone signals are stored in a permanent memory within the set.
In accordance with a particular illustrative embodiment of the invention, a mobile telephone set for transmitting and receiving voice and tone signals over co"~"~ ications channels comprises a radio transceiver; a tone signals receiver 25 connected to the radio transceiver; actuating means for selectively placing the mobile telephone set in a program mode; means responsive to the actuating means for enabling the tone signals receiver to receive, over the voice communication channel and via the transceiver, tone signals representative of mobile service authorization codes; and means for storing the received tone signals, thereby programming the 30 mobile telephone set with corresponding mobile service authorization codes.

Further features and advantages of the present invention will become a~par~nt from the following detailed description taken together with the drawings in which:
FIG. 1 is a schematic block diagram representation of a wireless telephone co"""~ ic~tion configuration in accordance with an embodiment of the invention; and FIG. 2 is a block diagram configuration of a wireless telephone set in accordance with a preferred embodiment of the invention.
10 Detailed Description Shown in FIG. 1 is a schematic representation of a wireless cu"~",l,nication configuration which illustratively includes a telephone switching office (TSO) 100 which is adapted to link a wireless telephone set 101 into a regional or nationwide telephone network (not shown). A base station 102, coupled to the 15 TSO 100, via a bidirectional communication link 103, is arranged to be in radio frequency co"~"lllnications with the wireless telephone set 101 via a radio frequency antenna 104. Also shown in schematic form, is a co"".,llnications service provider center 105 adapted to be coupled to the TSO 100 via another bidirectional link 106.
The service provider center 105 includes, inter alia, a telephone private branch20 exchange (PBX) 107, and a service attendant station 108 coupled to the PBX 107. It is well within the spirit and scope of the present invention that the wireless telephone set 101 may include a fixed wireless telephone station, a mobile/cellular telephone set, or a cordless-type telephone set.
The principles and features of the present invention shall be hereafter 25 described in connection with FIG. 1 Upon the purchase or lease of the wireless telephone set 101, a prospective subscriber would be assigned by the vendor or lessor a valid wireless telephone number which typically would include an area or regional code number followed by a station number. In order for the subscriber to be able to use the wireless telephone set 101, a telephone service provider or reseller, of 30 the subscriber's choice, must authorize such use by prog~ g the set 101 so that it is identifiable within the wireless telephone network as an authoriæd and legitimate wireless service subscriber/user. The programming of the set 101 is achieved by having the subscriber dial, out of the set 101, a predetermined service center number to first establish a coll"llllnication path with the service provider 35 center 105 via the radio antenna 104 and base station 102, the bidirectional link 103, -2~ 00 the TSO 100 and the other bidirectional link 106. Once the communir~tion path isestablished between the telephone set 101 and the service provider center 105, the subscriber/user can verbally, or by means of the telephone set dial, convey to an ollel~ol at the service attendant station 108 any requested subscriber-specific 5 information. In accordance with an illustrative embodiment, the telephone set 101 is equipped with a program activating key 109 adapted to bridge an audio signal receiver (not shown), which is located within the telephone set 101, onto the then currently established communication path with the service center 105. In turn, the operator at the attendant station 108 would bridge an audio signal transmitter located 10 at the center onto the communication path. The foregoing in effect couples the tr~n~mitter at the center 105 with the telephone set signal receiver so that the service Op~,ldlOl can remotely enter information directly into the set 101. As mentionedabove, the information intended to be entered and stored in the telephone set 101 is specific to the subscriber owner or lessee. In the case of cellular mobile 15 communication services, such information is referred to as Number Assignment Module (NAM) designation parameters. A sample of such NAM designations that can be remotely downloaded into the telephone set 101 are listed in the following table:
System Identification 00022 Telephone Number 2013866366 Access Overload Class 06 Group Identification 10 Initial Paging Channel 0334 Security Lock Code 6366 Local Use Flag A/B System Selection Min Mark Flag The service operator at the station 108 can either use a telephone keypad as means for generating and transmitting the above NAM designation parameters, or 30 alternatively can enter the above-listed information into a data termin~l, e.g. a colllpul~;l, that is coupled to a signal transmitter, e.g. a DTMF generator. In the above example, a total number of NAM characters to be tr~nsmitted includes 30 digits, with each digit having a value of 0 through 9. With the addition of an initial character to denote the beginning of transmission (e.g. "*"), an ending character to 35 indicate the end of transmission (e.g. "#"), and, for example, a three-digit cyclic - 204~800 redundancy check (CRC) coding segment, the information is tr~n~mitted as follows:
*000222013866366061003346366111#BBB
wherein BBB is a CRC 8 checksum byte. Once the above information is received, detected and stored in the telephone set 101, the latter is switched back into normal 5 (i.e., voice) telephone service operation at which point the subscriber user is informed by the service operator that the telephone set 101 is fully programmed and ready for use.
Referring now to FIG. 2, there is shown in functional block diagram form, a wireless telephone 200 in accordance with a plerelled embodiment of the 10 invention. The wireless telephone 200 comprises a radio transceiver portion 201 which includes a radio frequency receiver/transmitter 202 coupled to an antenna 203 and adapted to receive and transmit signals from and to a base station, e.g. a mobile cell site, or another wireless telephone. Coupled to the receiver/transmitter 202, via a bidirectional message connecting lead 204, is a processor 205 capable of receiving 15 and processing system message-type signals. Also coupled to the receiver/transmitter 202, via another bidirectional lead 206, is a processor 207adapted to process data signals as well as audio signals originating or received at the wireless telephone 200. Audio and data signals present on lead 206 are those signals intended for and derived from the antenna 203.
Within the radio transceiver 201, a controller 208 is coupled to the message processor 205 and the audio processor 207, via a control bus 220, which is also coupled to the receiver/tr~n~mitter 202. A voice handset interface circuit 209 interconnects the audio processor 207 and a telephone handset 210. In accordancewith one illustrative embodiment, interposed between the voice handset interface209 and the radio transceiver 201 is a mode switch 211, which in turn is coupled to a signals receiver 212. The latter is coupled via lead 214, to the transceiver controller 208. During the remote programming, or NAM designation parameters downloading, of the telephone set 200, the mode switch 211 diverts signals received at the antenna 203 and present on output lead 213 of the audio processo} 207 to the signals receiver 212. The signals receiver 212 may be selected among known commercially available receivers, such as, for example, the Hitachi HD404678 4-bit microprocessor with an integral DTMF receiver. In the case where the progl~mmillg signals out of the audio processor 207 and present on lead 213 are in digital form, the signals receiver 212 couples such digital signals to the controller 208 wherein an internal controller processing unit 215 directs such digital information for storage in a memory circuit within the controller 208, such as, for example, permanent read-only memory 216. Alternatively, if the programming information received at the antenna 203 is in the form of a sequence of tone signals, the receiver 212 (which in S such case would be a tone signals receiver) would connect such signals to an analog-to-digital converter 217 located within the controller 208. The digital output signals generated by the converter 217 would next be stored in the memory circuit 216 under the control of the processing unit 215.
Although the present invention has been described in connection with 10 particular embodiments thereof, additional embodiments, modifications and applications which will be apparent to those skilled in the art are included within the spirit and scope of the invention. For example, although the remotely pro~ m.llillg of a wireless phone is described above with reference to touch tone-type signaling, other signaling techniques and sequences, whether digitally encoded or not, may be 15 used to accomplish the remote downloading of NAM designation parameters.
