Definitions

  • the present invention relates generally to telecommunication systems, and more particularly to connecting analog communications devices to a mobile communications network using a mobile telephone to emulate wireline communications services.
  • conventional mobile telephone service does not allow for the easy connection of communications devices when at a fixed location, such as at home or at work.
  • An improved apparatus for connecting communications devices to a mobile communications network using a mobile telephone would also meet the needs of those users desiring a single telephone number.
  • the present invention is directed to an apparatus for connecting communications devices to a mobile communications network using a mobile telephone.
  • a serial interface couples the mobile telephone to BORSCHT means that provides BORSCHT functionality.
  • BORSCHT Battery, Overvoltage, Ringing, Supervision, Hybrid
  • a two-wire line port couples the BORSCHT means to an analog communications device, such as a standard telephone, referred to herein as a "plain old telephone" (POT), a fax machine, or a computer modem.
  • Conversion means coupled between the two-wire line port and the serial interface, converts the digital signals from the mobile telephone into analog two-wire line signals, and vice versa.
  • the present invention allows a communications device to place or receive a call over the mobile communications network, using the mobile telephone's radio unit to establish a wireless connection, in the same manner as if the communications device were connected to a wireline service.
  • a feature of the present invention is that a mobile telephone can be used to provide wireline-like functionality in areas where wireline service is unavailable or cost prohibitive.
  • Communications devices designed to operate over a wireline network communicate via a two-wire line port.
  • the present invention allows these devices to access a mobile communications network in the same manner they would if connected to a wireline network.
  • the present invention can provide connections to multiple telephones in a home or business, that appear to the user to operate as though they were connected to a wireline service. For example, a dial tone is provided when the handset is picked up, and a call is connected automatically after the appropriate number of digits have been entered — functions typically associated with wireline service but not associated with many mobile telephones.
  • the present invention includes a docking unit and a mobile telephone. Combining, or "docking", the mobile telephone with the docking unit activates the attached communications devices. However, the user is free to remove the mobile telephone and use it like any other mobile telephone when away from the docking unit. From a marketing perspective, many users who do not already have a mobile telephone might be enticed to become mobile subscribers once they experience the advantages of mobile telephone use.
  • the docking unit can be removed once wireline services become available, but for those desiring to enter into a mobile subscriber agreement, the mobile telephone can be left behind.
  • the present invention therefore allows a telephone provider to leverage wireline services to capture new, higher-margin mobile telephone subscribers.
  • Another feature of the present invention is that multiple and varied communications devices can be connected to a mobile communications network using a single mobile telephone.
  • the present invention when placed in a home can provide wireline-like connections for a fax machine, a computer modem, and multiple POTs.
  • the mobile telephone can be used in normal fashion for conventional mobile applications, for 4 example, while driving in the car.
  • the mobile telephone can then be docked with the docking unit to "activate" the attached communications devices.
  • Such a docking unit can be used wherever wireline services would typically be used, such as in a home or business. Now, however, since all calls are routed through the mobile telephone, the user can always be reached at the same telephone number.
  • Another advantage of the present invention is that the functionality of the mobile telephone is used in conjunction with the functionality provided by the BORSCHT means in the docking unit to provide the desired connection to the mobile communications network. Those functions provided by the mobile telephone do not need to be replicated in the BORSCHT means, which results in a cheaper, smaller, less complex docking unit. Design time of the docking unit is also reduced because those functions provided by the mobile telephone do not have to be re-designed in the docking unit.

  • the two- wire line that would be plugged into a wireline wall socket is plugged into a two-wire line port 116 in docking unit 102.
  • the combination of mobile telephone 104 and docking unit 102 provides all the functionality one would expect from wireline service, including, but not limited to, a dial tone, automatic /immediate "send” to eliminate the need for a SEND command after digits are dialed (referred to herein as call origination), and lighting the telephone keypad.
  • Wireline functionality is referred to collectively within the 6 art as BORSCHT functionality, and describes the "look and feel" of wireline telephone service.
  • mobile telephone 104 provides some BORSCHT functionality, and also provides the radio and antenna necessary to communicate with mobile communications network 106 via wireless link 108.
  • Docking unit 102 provides the necessary interfaces /ports between mobile telephone 104 and communications devices 110, as well as whatever BORSCHT functionality is not provided by mobile telephone 104.
  • Docking unit 102 is preferably built to match a particular mobile telephone 104, or with a particular family of mobile telephones 104 that share certain functionality, in the sense that docking unit 102 preferably provides whatever BORSCHT functionality is not provided by mobile telephone 104. As mobile telephones 104 become more sophisticated and provide greater BORSCHT functionality, docking unit 102 can become less sophisticated, less expensive, and more compact. This design allows for the maximum leveraging of the functionality of sophisticated mobile telephones.
  • Docking unit 102 can also provide a charging interface for charging the mobile telephone's battery, a standard AC adapter, an external antenna jack (for improved reception), and an RS-232 data port for connecting digital communication devices.
  • Mobile communications network 106 is preferably an IS-95 code division multiple access (CDMA) wireless network, and wireless link 108 represents an appropriate CDMA modulated signal transmitted over the air. It will be apparent to those skilled in the art that the present invention will be operable with other wireless communications systems, such as time division multiple access (TDMA), GSM, etc., systems.
  • CDMA code division multiple access
  • TDMA time division multiple access
  • GSM Global System for Mobile communications
  • mobile telephone 104 must therefore be capable of transmitting and receiving the CDMA modulated signals used by mobile communications network 106.

  • docking unit 102 has a single two-wire port 116. A port extender could then be used to attach multiple communications devices 110, but would effectively operate in the same manner as the preferred embodiment.
  • docking unit 102 When mobile telephone 104 is not docked with docking unit 102 (that is, when mobile telephone serial port 114 is not coupled with docking unit serial port 112), docking unit 102 remains in an inactive state. Without the radio transmitter of mobile telephone 104, docking unit 102 has no way of communicating with mobile communications network 106.
  • docking unit 102 remains in an active state.
  • Mobile telephone 104 does not ring in the active state when incoming calls are received from mobile communications network 106. Rather, the incoming call is passed along to 8 communications devices 110, just as though they were attached to a single line for wireline service.

Abstract

L'invention concerne un appareil (102, 104) destiné à connecter des dispositifs (110) de communications à un réseau (106) de communications mobiles à l'aide d'un téléphone mobile. Une interface série (112, 114) couple le téléphone mobile (104) à un dispositif BORSCHT (204) assurant des fonctions BORSCHT. Un port (116) pour ligne deux fils permet de coupler le dispositif BORSCHT à un dispositif (110) de communications analogiques, tel qu'un téléphone classique, un télécopieur, ou un modem informatique. Un convertisseur (202) monté entre le port (116) pour ligne deux fils et l'interface série (112,114) transforme en des signaux pour ligne deux fils les signaux numériques en provenance du téléphone mobile, et vice-versa. Le dispositif (110) de communications peut alors établir ou recevoir un appel via le réseau (106) de communications mobiles, en utilisant le module radio (208) du téléphone mobile pour établir une connexion radio, de la même manière que si le dispositif de communications était connecté à un service filaire.
