Description




TECHNICAL FIELD




The present invention relates to a system and method for wireline based registration of wireless devices.




BACKGROUND ART




In a wireless communication system, a personal communication service (PCS) system provides service to wireless devices that are in areas contained within cells or micro cells of the system. Although for any particular wireless device within the overall service area, the PCS can provide a communication path between the wireless device and a call destination, the PCS does not have the intelligence to determine the physical location of the wireless device. That is, location approximation technologies and techniques are generally not incorporated into the PCS. Existing location approximation technologies such as time-of-delivery and global positioning systems are complex in nature, and cannot be readily or easily incorporated into a PCS.




For the foregoing reasons, there is a need for a wireless communication system that overcomes the problems and limitations of the prior art.




DISCLOSURE OF THE INVENTION




It is, therefore, an object of the present invention to provide a system and method for wireline based registration of wireless devices.




In carring out the above object, a location registration system for wireless devices is provided. The system comprises a wireless device, a terminal, and an authentication center. The wireless device has a tag with a tag identity. The tag transmits a signal indicative of the tag identity. The terminal is connected to a wireline loop that defines a terminal location for the terminal. Further, the terminal is operative to receive the signal from the tag and further is operative to send a signal over the wireline loop that is indicative of the tag identity and the terminal location. The authentication center is in communication with the terminal, and receives the signals from the terminal.




In a preferred embodiment, the tag is in the form of a strip, and the wireless device includes a pair of power terminals. The strip is positioned to be in communication with the pair of power terminals to provide power to the strip for transmitting the signal indicative of the tag identity. The wireless device may be, for example, a wireless phone. Alternatively, the tag may be in another suitable form such as a microchip.




Further, in a preferred embodiment, the system includes a network configured to provide communication between the terminal and the authentication center. The network may include, for example, a circuit-switched network, a packet-switched network, or a local area network. Further, the system preferably includes a local switch connecting the wireline loop to the network.




Preferably, the wireless device has a device identity. The authentication center processes the tag identity to determine the device identity. As such, it is possible for the authentication center to determine the identity of a wireless device and the location of that wireless device, when the wireless device comes within range of the terminal. Preferably, the device identity includes an electronic serial number and a mobile identification number.




Further, in a preferred embodiment, the system includes a service location register. The authentication center communicates or registers the device identity with the service location register.




Further, in carrying out the present invention, a component for identifying a wireless device is provided. The component comprises a tag for placement on the wireless device. The tag has a tag identity, and is operative to transmit a signal indicative of the tag identity for reception by any one of a plurality of terminals. Each terminal is connected to a corresponding wireline loop defining a terminal location for that terminal. This allows a receiving terminal to send a signal indicative of the tag identity and the receiving terminal location over the wireline loop connected to the receiving terminal.




Preferably, the tag identity is a sequence of characters; and, the sequence has a length of between about 15 characters and about 28 characters. Further, the characters are preferably bar code characters that form a bar code inventory tag. Still further, preferably, the tag transmits the signal over a range having a radius that is between about 15 centimeters and about 20 centimeters.




Still further, in carrying out the present invention, a method for registering a wireless device is provided. Be method comprises transmitting a signal from a tag on a wireless device, receiving the signal at a terminal, sending a signal from the terminal over a wireline loop, and receiving the signal from the terminal at an authentication center.




The advantages associated with embodiments of the present invention are numerous. For example, systems and methods of the present invention allow the PCS carrier to locate wireless terminals to a specific wireline loop location. Unlike time of shivery, global positioning systems and other location approximation technologies and techniques, embodiments of the present invention provide systems and methods that allow the wireless device to be registed to a specific wireline loop location. Advantageously, suitable implementation of the authentication center allows the PCS carrier to place the tag on the wireless device and record the tag identity and corresponding device identity at the authentication center such that the information is readily available to register the location of the wireless device during later use by an end user.




There are many benefits that may be achieved with the embodiments of the present invention. For example, the authentication center may be used to determine a specific wireline loop location for a wireless device when the wireless device places an emergency call such as a call to the police, fire department, or any other emergency call such as 911 calls where such service, is available.




The above object and other objects, features, and advantages of the present invention are readily apparent from the following detailed description of the best mode for carring out the invention when taken in connection with the accompanying drawings.

BEST MODE FOR CARRYING OUT THE INVENTION




With reference to

FIG. 1

, a system of the present invention for dynamic location registration is generally indicated at


10


. System


10


includes a wireless device


12


having a tag


14


. Tag


14


has a tag identity. Tag


14


transmits a signal


16


indicative of the tag identity. A terminal


18


is connected to a wireline loop


20


. Wireline loop


20


defines the terminal location. That is, in order to more greatly appreciate the advantages of the embodiments of the present invention, system


10


preferably includes additional terminals


19


, with each terminal connected to a corresponding wireline loop


21


. As such, a plurality of wireline loops may cover a wide geographical area with individual terminals located throughout the area. In this way, wireless device


12


may be moved throughout the entire area of coverage, moving into and out of range with different terminals of the system. Terminal


18


operates as a receiver over a range


22


. An appropriate range for terminal


18


is based on a variety of factors including the spacing of different terminals from each other.




It is to be appreciated that the term “wireless device” as used herein is meant to include any device that receives a tag. That is, a device is wireless in that the device does not have a permanent physical connection to a terminal. That is, although wireless communication device such as wireless phones are used in one suitable implementation, the term “wireless device” is intended to be far reaching. For example, a laptop computer and personal organizer are both possible “wireless devices”. Further, for example, even a vehicle such as a truck my be tagged, making the truck a wireless device to allow location tracking thereof. The examples above are illustrative only, and the term “wireless device” shall be interpreted to encompass any device receiving a tag and lacking a permanent physical connection to a terminal. Of course, as described later herein, the wireless device preferably has a battery that provides power for the tag when the tag is placed between points of sufficient difference in potential, such as the battery terminals. In a laptop embodiment, the tag may be connect to the laptop via a Personal Computer Memory Card International Association (PCMCIA) slot or other suitable expansion slot that is present.




Wireline loop


20


, and any other wireline loops


21


are preferably routed through local switches


24


to a network


26


. Network


26


allows signal receiving terminal


18


to communicate with an authentication center


28


.




Terminal


18


is operative to receive signal


16


from tag


14


and in response, send a signal over wireline loop


20


through switch


24


and network


26


to authentication center


28


. The signal from terminal


18


is indicative of the tag identity and of the terminal location as defined by the specific wireline loop


20


. As such, the information received at authentication center


28


tells authentication center


28


the tag identity for wireless device


12


(that is, which device is present) and the terminal location of terminal


18


(that is, where wireless device


12


is at).




Of course, it is to be appreciated, that it is only neccessary that textual


18


and any other terminal


19


be in communication with authentication center


28


to allow the sending of the tag identity and terminal location from terminal


18


(or any other terminal


19


) to authecaon center


28


. As such, network


26


may include, for example, a circuit-switched network, a packet-switched network, or a local area network. Further, a circuit-switched network may include the public switched telephone network (PSTN). Still further, a packet of switched network may include an Internet protocol network such as a transmission control protocol/Internet protocol (TCP/IP) network. Even Thrice, a local area network may include a network extending through a building or building complex with the wireline loop drops located at various locations in he building or complex such as at elevators, conference rooms, etc. Of course, it is to be appreciated that any of the above-named network types or any other networks, alone or in combination, May be suitable for applications of the present invention.




In a preferred embodiment, authentication center


28


determines a device identity that corresponds to the tag identity received with the terminal location. In such an embodiment, the tag identity and device identity are preferably cataloged together at the authentication center when tag


14


is put on device


12


. As such, when authentication center


28


receives the tag identity (and terminal location), the tag identity can be matched up with the corresponding device. Preferably, the device identity includes an electronic serial number and/or a mobile identification number. By configuring authentication center


28


to determine device identities that correspond to the tag identities, implementation of embodiments of the present invention is facilitated. That is, a distributor may receive wireless devices


12


after a permanent serial number has been assigned to each wireless device. Further, the distributor may assign further identification to the device such as a mobile identification number that is preferable the same as the telephone number when the device is a phone. Still futher, a distributor may simply have a large mass produced collection of tags. Implementation of authentication center


28


allows any tag to be selected and applied to any wireless device


12


, and then a record is made of the tag identity and corresponding device identifiers (electric serial number and/or mobile identification number) at authentication center


28


. Later, when authentication center


28


receives the tag identity and terminal


18


location, authentication center


28


may readily and easily determine the device identity of the wireless device based on the tag identity, and may determine which terminal that wireless device is located at based on the terminal identity as defined by wireline loop location.




It is to be appreciated that teals


18


and


19


may be located anywhere that a wireline drop is present. Of course, it is possible, that telephones


32


or other devices are located at these wireline drops, but it is to be appreciated that this is not required. As such, it is to be appreciated that terminals


18


and


19


may be located at any wireline drop, such as, for example, at traffic lights, or wiring in a building or other structure, such as street lights. Preferably, authentication center


28


communicates or registers device identity and location at a service location register such as a wireless service location register (WSLR)


34


. Of course, WSLR


34


may include authentication center


28


or may be separated therefrom.




With reference to

FIGS. 2 and 3

, a wireless device having a tag in accordance with the present invention is generally indicated at


50


. Wireless device


50


is a wireless telephone; but, of course, it is appreciated that other devices may be tagged. Wireless device


50


includes speaker


52


and microphone


54


. Further, keypad


56


allows a user to dial out. As shown in

FIG. 2

, a tag


58


preferably is in the form of a strip. In a preferred embodiment, tag


58


is an active transmitter and is positioned across a pair of battery terminals


60


and


62


. A battery


64


has the primary purpose of powering wireless device


50


. Tag


58


is preferably configured to always draw power from battery


64


. However, power drawn by tag


58


is preferably almost negligible relative to the amount of power required to operate wireless device


50


. This is preferred to reduce the effects of tag


58


on the useful life of device


50


on a full-charged battery. As mentioned previously, in an alternative to tag


58


(FIG.


2


), as shown in

FIG. 3

, a microchip


66


may be used to transmit the tag identity. Of course, it is to be appreciated that tag


58


is the current preferred embodiment of the present invention due to the lower cost and easier implementation thereof.




Referring to

FIG. 4

, a method of the present invention for dynamically registering a wireless device location to a specific wireline loop location (or the location) is generally indicated at


80


. At block


82


, the tag transmits the tag identity for reception by a nearby terminal (preferably of a plality of terminals). At block


84


, a terminal receives the tag identity. At block


86


, the receiving terminal sends a signal over the wireline loop to an authentication center. The signal sent by the terminal indicates the tag identity and fiber indicates the terminal location. At block


88


, the authentication center receives the sent information. At block


90


, the authentication center determines device identity based on the tag identify, and advantageously notes the location of the wireless device based on the terminal location. As such, the specific wireless device and its specific location at a specific wireline loop of a potentially large network having many wireline loop drops is determined.




It is to be appreciated that the device identity as determined by the authentication center may include specific device identification items. For example, at block


92


, the electronic serial number of the tagged wireless device is detention by examining the tag identity received at the authentication center. Further, at block


94


, the mobile identification number corresponding to the wireless device sending the tag identity is determined at the authentication center by examining the tag identity received.




In one suitable bilementation the tag at the signal indicating tag identity over a range having a radius between about 15 centimeters and about 20 centimeters. Further, in a suitable implementation, the tag identity is a message that is a sequence of characters having a length of about 15 to about 28 characters. The characters are preferably bar code characters that form a bar code inventory tag. Further, a suitable bar code tag way be a metallic inventory strip. Further, in one suitable implementation, the tag draws about 7 milliamps of current from the battery of the wireless device. Still further, in a suitable implementation, the terminal broadcasting antenna draws about 50 milliamps of current and has a range of about 3 meters in radius.




Additionally, in embodiments wherein some or all of the terminals have telephones or other communication devices connected to them, it is preferred that the tag and the terminal comnunicate with each other over a bandwidth that is outside of the bandwidth used for the telephones or other devices. As such, in a preferred implementation, the terminal and tag can communicate with each other while the telephone or other device is in use. Of course, in some applications it may be appropriate to share the same bandwidth, and if desired, use appropriate techniques to allow sinmltaneous use of the bandwidth by the telephone and the terminal.




While embodiments of the invention have been illustrated and described, it is not Fin ed that these embodiments illustrate and describe all possible forms of the invention. Rather, the words used in the specification are words of description rather than limitation, and that various changes may be made without departing from the spit and scope of the invention.
