PCT No. PCT/SE96/00210 Sec. 371 Date Aug. 15, 1997 Sec. 102(e) Date Aug. 15, 1997 PCT Filed Feb. 16, 1996 PCT Pub. No. WO96/25830 PCT Pub. Date Aug. 22, 1996The position of a mobile station in a cellular mobile telephone system, particularly a GSM system, is determined by carrying out a simulated call setup, i.e., the call setup is interrupted subsequent to a telephone switching center (MSC) having received a paging response containing the identity of the cell and, optionally, a timing advance. The simulated call setup is initiated by generating a modified short message signal (SMS) which is not registered in the SMS catalogue of the mobile station and which is not shown to the user of the mobile station. The SMS commands the mobile station to carry out a position determining sequence in order to establish parameters for use in establishing the position of the mobile station, for example by commanding the mobile station to connect itself to a base station contained in its neighbor list, analyze the geographical position of the base station, and subsequently send the position determining parameters to a position handler. The geographical position of the base station is analyzed from the cell identity and, if available, the timing advance, the position of the mobile station being presented graphically on a picture screen and constantly updated after each call setup. The call setups are generated by the position handler.

This invention relates to the use and proper placement in a vehicle of a mobile wireless phone having cellular or GPS positioning capability and an impact sensor, e.g. triaxial accelerometer. Said sensor instantly detects a serious vehicular accident or theft, then and without driver or passenger intervention, automatically transmits an emergency appeal for assistance to appropriate Police/Emergency Medical Services (PEMS), or Fire Rescue units, apprizing the PEMS of said exigency and location. Otherwise, the integrated mobile phone system will function in a manner that is similar to a conventional wireless mobile phone. Optionally, the integrated mobile wireless phone may include means for receiving an emergency medical signal and automatically communicates an appeal for emergency assistance when the user having said unit and having a predisposed life threatening medical condition, encounters a life threatening anomaly, e.g., heart attack. System provides means to mitigate multi-vehicle collisions that are normally associated with environmental road hazards fog, ice, etc., by instantly alerting authorities and/or drivers in the region of the location of said hazard when an accident occurs.

An improved electronic lock system is provided for use with real estate lock boxes where there is the need for many people to access the secured compartment of the lock box in a controlled manner. Each user has an identification card with a non-volatile secure memory (known as a “smart card”), for exchanging data with the lock box, and with a portable computer capable of reading data from the smart card; or a cell phone can be used to gain access information from a central computer. The user first inserts the smart card into the connector attached to the lock box; the lock box reads the user's ID stored in the smart card memory and records this information in lock box memory. The lock box then transfers its access code information and other data to the smart card for further processing. The user then inserts the smart card in a portable card reader to learn the access code, or calls a central computer via a mobile phone system and interacts with the computer to elicit the necessary access code information. The access code is then manually keyed into the lock box keypad by the user to obtain access to the secure compartment.

In response to a call from a telephone terminal (4) to a mobile terminal (1), a mobile phone network (2) confirms the moving state of the mobile terminal (1). If the mobile terminal (1) is found to be moving, the mobile phone network (2) notifies the mobile terminal (1) of the fact that a call was received by the mobile terminal (1) and also notifies the caller's telephone terminal (4) of the fact that the called party's mobile terminal (1) is moving, and causes the caller's terminal (1) to call again after the lapse of a predetermined time. If the called party's terminal (1) is found to be not moving, the mobile phone network (2) transmits a calling signal to the mobile terminal (1).

A method of measuring the distance between a mobile phone and a base station based on the round-trip delay (RTD) of a prescribed message transmitted from the base station to the mobile phone in a cellular mobile telephone system (CMTS), comprising the steps of calculating a mean error distance to adjust the distance between the base station and the mobile phone within the cell boundary of the base station, measuring the RTD between the base station and the mobile phone positioned at an arbitrary point within the cell, calculating the RTD distance between the base station and the mobile phone based on the RTD measurement by subtracting the mean error distance from the RTD distance.

A mobile telephone system provides a subscribe with services, for instance call barring and call forwarding, in dependence on the circumstances of the subscriber's mobile station. For instance, if the mobile station has a first network as its home network, the services provided are modified if it is detected that the mobile station has registered with a second network. In particular, international calls may be barred when on the home network, but permitted when on the second network so that the user may call his home country. This is carried out by having a number of different service profiles stored in the home network, for controlling the interactions between the mobile telephone and the current network, these service profiles being selected according to which network the mobile telephone is currently working to.

A pseudo-random number generator (PRNG) for a cryptographic processing system is disclosed in which the PRNG is reseeded at each instance of input entropy and in which a standard timestamp variable used in determining random sequence outputs is replaced with a running counter. The method employed by the PRNG demonstrates increased resistance to iterative-guessing attacks and chosen-input attacks than those of previous technologies. The PRNG is suitable for use in, for example, a mobile telephone system for accomplishing secure communications.

A security procedure for a Universal Mobile Telephone Service (UMTS) mobile communication system includes detecting a communication failure between a Radio Network Controller (RNC) which controls radio coverage within a prescribed geographical area and a Mobile Station (MS) in the geographic area, authenticating the MS and setting a new security parameter in response to the communication failure. The security parameter to be changed may be a ciphering key CK or an integrity key IK. Moreover, the steps of authenticating and setting a new security parameter may be performed separately or simultaneously.

A mobile telephone system providing general packet radio service (GPRS) includes a radio network controller (RNC) (2A) and/or a base station controller (BSC) and an associated serving GPRS support node (10A) for each domain. The RNCs (2A) and the SGSNs (10A) are interconnected by an Internet protocol (IP) network. When a mobile telephone (6A) moves from one domain to another, the RNC, in the new domain, takes over handling the mobile telephone. The current SGSN (10A) has a detector (20) which detects whether the existing transmission is a real-time transmission and, if it is, a diverter (22) comes into operation to couple the RNC in the new domain to the current SGSN (10A) rather than its associated SGSN (10A). When the call ends, the current SGSN (10A) hands-over the call to the SGSN (10A) in the new domain. This procedure ensures minimal interruption to real-time services by keeping the call anchored to the current SGSN (10A).

A procedure to transmit information at a telephone answering service, especially in mobile telephone systems. The telephone answering service has a voice mailbox for recording of speech, and also transmits a text message to the mobile telephone especially via SMS (short Message Service). The procedure makes possible an improved functionality in the system in so far as the text message is transmitted in parallel to the mobile telephone from which listening to the voice mailbox is performed. The text message usually contains a telephone number which can be connected with applications in the mobile terminal. The procedure makes it possible that telephone numbers or personal messages, manually or automatically, are stored in the mobile answer function and are transmitted to the listening mobile terminal.

Base stations exchange information with users over first wireless communication links. A mobile switching center provides mobile telephone service. An Internet access system provides Internet access service. A data system provides a data service. An Ethernet backhaul system uses an Ethernet format to exchange the information between the base stations and the mobile switching center, the Internet access system, and the data system. Wireless interfaces are coupled to the base stations and are configured to exchange the information over second wireless links. Individual base stations detect a fault in the Ethernet backhaul system, and in response, to route the information away from the Ethernet backhaul system and to the wireless interfaces to provide service restoration.

The digital data can be from a digital camera that is integrated with the mobile, or cellular, phone. The discontinuous transmission system of the mobile phone system is modified to include a transmission handler that is used to control the packetizing of the digital data to be transmitted within the voids in the transmitted speech determined by a voice activated detector. A reception handler is added to the discontinuous transmission system to allow the extraction of the digital data from the transmitted mobile phone system signal.

An apparatus and a method for interacting with a mobile telephone are provided. A remote control unit receives a user command and transmits it to a TV system which recognizes the user command as a telephone function command and transmits the function command to the mobile telephone if the TV system is set to Telephone Mode. The TV system may also output data received from the mobile telephone in response to the transmitted function command. Thus, a user may interact with a mobile telephone using an interactive TV system by displaying text/image data received from the telephone and by inputting various telephone function commands using a remote control unit. Upon receiving a function command from the TV system, the mobile telephone generates output data in response to the function command and transmits itto the TV system. A display unit of the TV system displays the text/image data, and a speaker outputs the sound data. As a result, a user may conveniently interact with a mobile telephone using a display unit and a speaker of an interactive TV system with a remote control unit.
