Digital wireless telephone system for downloading software to a digital telephone using wireless data link protocol
A digital wireless telephone downloads software related to digital telephone services using a client browser. The digital telephone initiates a data call to an interworking unit via a digital wireless telephone network, using a prescribed wireless data protocol such as IS-95A. The interworking unit recovers the payload of the wireless data packets to establish a two-way data link with the digital telephone. The interworking unit sends data messages to a destination server across a second two-way data link in a packet switched network to establish a two way session between the digital telephone and the destination server. The user of the digital telephone can thus communicate with the server via a two-way application-layer session using hypertext-based messaging. The digital telephone can thus navigate between different servers on the packet switched network for activation of different digital telephone services, and for downloading new software or updating existing software related to the digital telephone services.
1. A method of programming digital telephone services in a digital telephone in communication with a digital wireless communications system, comprising:
initiating a two-way network link, from the digital telephone to an interworking unit via a digital wireless base station transceiver, for sending and receiving data packets according to a prescribed wireless data protocol;
establishing a two-way session between the digital telephone and a server via the two-way network link by sending from the digital telephone a network address corresponding to the server, the server being in communication with the interworking unit via a packet switched data network, wherein the establishing step includes:
(a) supplying a menu list from the server to the digital telephone; and
(b) executing a browser application stored in the digital telephone and configured for displaying the menu list on the digital telephone;
outputting by the browser application a selection input to the server in response to a user selection from the menu list; and
downloading control software associated with the digital telephone services to the digital telephone via the digital wireless base station transceiver in response to the selection input being supplied by the digital telephone during the two-way session.
2. A method of programming digital telephone services in a digital telephone in communication with a digital wireless communications system, comprising:
initiating a wireless data call from the digital telephone to an interworking unit via the digital wireless communications system in response to a user input, to initiate a two-way network link from the digital telephone to the interworking unit for sending and receiving data packets via a digital wireless base station transceiver according to a prescribed wireless data protocol, wherein the step of initiating a wireless data call includes calling the interworking unit based on a telephone number input by the user of the digital telephone;
receiving a selection input supplied via the digital wireless base station transceiver by the digital telephone, during the two-way session; and
downloading control software associated with the digital telephone services to the digital telephone via the digital wireless base station transceiver during the two-way session, in response to the received selection input.
3. The method of claim 2 , wherein the step of establishing the two-way session includes:
supplying dial-digits corresponding to an activation request from the digital telephone to the interworking unit; and
forwarding the activation request from the interworking unit to the server in response to reception of the corresponding dial-digits by the interworking unit.
4. A method of programming digital telephone services in a digital telephone in communication with a digital wireless communications system, comprising:
initiating a wireless data call from the digital telephone to an interworking unit via the digital wireless communications system in response to a user input, to initiate a two-way network link from the digital telephone to the interworking unit for sending and receiving data packets via a digital wireless base station transceiver according to a prescribed wireless data protocol, wherein the step of initiating a wireless data call includes calling the interworking unit using a telephone number stored in the digital telephone;
receiving a selection input supplied via the digital wireless base station transceiver by the digital telephone, during the two-way session; and
downloading control software associated with the digital telephone services to the digital telephone via the digital wireless base station transceiver during the two-way session, in response to the received selection input.
