Definitions

  • This invention relates to a method for facilitating retrieval of a mobile phone.
  • Cellular telecommunications devices also called mobile phones (devices that communicate with base/cell stations through wireless means), offer a level of portability and convenience that is not possible with traditional communication devices.
  • Mobile phones are increasing in complexity and functionality and will offer widespread portable computing and Internet access capability in the near future. Accordingly, it is expected that these devices will become even more valuable to their owner due to the volume and importance of information contained in the mobile phone.
  • the ability to locate a caller from a mobile phone has opened the opportunity for carriers to facilitate location-based services.
  • Some of these services include Emergency Roadside Assistance, Location Sensitive Billing and Enhanced "4-1-1" (a service that can provide location based information such as nearby gas stations, restaurants, etc). All such systems utilise information obtained from traffic during an active call from the mobile phone. These systems are not suitable for providing location information if a call is not being made from the mobile phone.
  • the present invention aims to provide another location-based service, the ability to locate and efficiently facilitate retrieval of a lost mobile phone.
  • this invention by its very nature does not rely upon a call being made from the mobile phone.
  • the loss of a mobile phone can be costly and can cause considerable inconvenience for the owner.
  • the mobile phone may contain the owner's phonebook of personal and professional contacts or more importantly, commercially sensitive information that may pose a more significant concern if accessed by an unauthorised person.
  • WTP's currently monitor the general location of mobile phones to maintain a home location register that describes the last known cell (a communications area covered by a network base station) location of all their active mobile phones.
  • This home location register is used to effectively monitor the mobile phone to maintain an efficient coverage for the user and to provide effective management of the WTP infrastructure.
  • location resolution is limited to simply knowing the cell that the mobile phone is within, which can be several square kilometres in area.
  • LSP's have developed several techniques to facilitate the more accurate location of a caller from a mobile phone within a cell. These systems typically make use of the fact that signals broadcast from the mobile phone will be received at multiple network base stations. By analysing the signal strength, angle of receipt or time of arrival, a quite accurate location (within meters) can be obtained using triangulation. Examples of such systems include Time Difference Of Arrival (TDOA), Angle Of Arrival (AOA) and Power on Arrival (PA). Other location systems include the Global Positioning System (GPS) which determines the position of the mobile phone using satellites.
  • GPS Global Positioning System
  • the present invention aims to solve the problem of an owner locating and retrieving a mobile phone if it is lost. This involves operations and procedures, which must be conducted remotely, as the mobile phone will not be in operation by the owner. This is quite different from the systems that have been developed that make use of location techniques to secure a stolen mobile phone that is actively being used by an unauthorised person.
  • US Patent 5,600,708 which describes a system for securing a stolen mobile telephone.
  • IMEI internal mobile equipment identity
  • a unique identifier of the mobile telephone referred to as the internal mobile equipment identity (IMEI) is checked against a list of stolen devices at the base station. If a match is found, a signal is sent to the telephone that locks the telephone to the SIM card that is currently in use. This prevents the telephone from being used with SIM cards other than the one that was in the telephone when the locking feature was activated.
  • IMEI internal mobile equipment identity
  • US Patent 5,748,084 describes a security system for a portable electronic device such as a laptop computer.
  • the system described includes a beacon with preferably a transmitter and a receiver, internal security logic imbedded in the mobile unit and external system elements for locating the beacon. If the device is reported stolen, a message is sent to the portable electronic device that instructs it to either transmit critical files to the owner, destroy critical files or encrypt them.
  • a beacon signal is also activated which aids in the location of the stolen portable electronic device.
  • a portable tracking device is used to home in on the beacon signal and find the device. This system does not require user intervention at the mobile unit however it requires additional hardware for locating and performing these operations.
  • the present invention interfaces with existing WTPs for the purpose of locating and efficiently retrieving a lost mobile phone. In addition it provides additional services tailored to the needs of the owner of the lost mobile phone. The methodology in which it provides these services within the current wireless infrastructure is unique.
  • a service provider facilitates retrieval of a mobile phone, the mobile phone being associated with a wireless telecommunications provider, comprising the steps of:
  • a client communicating a location request including identification information regarding the mobile phone to the service provider via means other than the mobile phone;
  • the service provider sending at least one predefined query to the wireless telecommunications provider for location information regarding the mobile phone;

  • Data transfer provides the user with a facility to obtain information from the mobile phone 24 without retrieval of the mobile phone 24. This allows any important information that is stored on the mobile phone 24 to be retrieved quickly.
  • the service provider 10 sends command instructions, using the server system 28, to the mobile phone 24 to command it to provide specified data by reply messages.
  • the command instructions include information specifying the data to be sent by the mobile phone 24.
  • the data can include contact details, stored documents, or e-mails stored in the mobile phone.
  • the data may be stored on the SIM card or in the mobile phone 24 itself.
  • Power down remotely activates minimal power mode on the mobile phone 24 to conserve battery power and therefore extend the potential retrieval period. Power is simply cut or minimised on non-essential systems such as the display allowing the power that is conserved to be used for more essential systems that aid in mobile phone 24 retrieval.
  • the service provider 10 sends command instructions, using the server system 28, to the mobile phone 24 to command it to enter power down mode and provide confirmation by reply message.
  • location information may be obtained by a stand alone location service provider that uses its own location technologies and infrastructure.
  • the invention is still applicable where the location information is obtained independently of the WTP, such as handset based location that uses GPS (General Positioning System).
  • the initial location request from the client may be made to the WTP who passes it on to the service provider.
  • future mobile phones may be provided with an off mode to enable the mobile phone 24 to be located even when the mobile phone 24 is switched off.
  • the off mode cuts power to all systems except those required to receive predefined messages. If the mobile phone 24 receives a predefined message when switched off, the mobile phone 24 activates the required systems to interpret and process the message, and thus carry out commands, such as location. It would be readily apparent to those skilled in the art that this invention may be used with such mobile phones.
