Abstract: A technique is used for providing additional information about a broadcast presentation that allows a user interested in the additional information to acquire it easily, using a selective call device or a television remote control device to easily acquire an information address during the broadcast when a prompt is presented during the broadcast. An advertiser can send the additional information over a wide area radio selective call communication system or can post it at a universal resource locator of a computer network. The information address is used to acquire the additional information. The information address can be stored, selected and deleted in the selective call device or remote control device. The prompt can be disabled or enabled manually or based on location.

Abstract: An improved home location register (HLR) that includes a switch capability mediation module for implementing switch capability mediation between different mobile switching centers (MSCs). According to the invention, when one MSC (home MSC of a receiving party) attempts to communicate with another MSC (serving MSC) via the HLR serving the home MSC, the mediation module determines whether the two MSCs are provided by different vendors and whether they implement different capabilities, based on the MPCM (MSC ID Point Code Map) file records of both the originating and serving MSCs. The MPCM files store MSCs' network configuration information.

Abstract: A method and apparatus for allowing an Authentication Center (AC) in a cellular telephone system to order SSD update and unique challenge operations only if the receiving MSC/VLR is receptive to performing them. The AC has access to an MPCM file that indicates the circumstances under which each MSC/VLR in the system will perform SSD updates and unique challenges. Thus, whenever the AC determines that it is desirable to send either an SSD update or a unique challenge, the AC first checks the MPCM file to determine whether the message should be sent. If the database indicates that the MSC/VLR will not attempt the operation, the AC does not request the operation.

Abstract: The present invention provides an improved home location register (HLR) that includes an application program for implementing configurable call forwarding bins in a mobile telephone system. According to the invention, a number of call forwarding bins are provided for subscribers. Each forwarding bin must be individually authorized to become available to a subscriber. Furthermore, if a bin is authorized, depending on whether a bin is locked or not, either the cellular carrier or the subscriber can activate the bin and/or modify a forward-to number in the bin. Moreover, a priority list is provided, corresponding to a particular status of the subscriber's cellular phone. (i.e. busy, no answer, etc.) and whether the subscriber is in the home area or a roaming area. The priority list identifies selected bin numbers that the application program needs to check. The bin that has the highest priority on the list and is authorized and activated will be selected.

Abstract: The system and method of the present invention facilitates an improved Home Location Register (HLR) that includes a fraud protection mediation module for use in a mobile telephone system. The fraud protection mediation module operates in any one of the following situations: (1) a registration notice (REGNOT) is received by the HLR from a Mobile Switching Center (MSC) currently serving a subscriber in a roaming area; (2) a qualification request (QUALREQ) is received by the HLR from a serving MSC for obtaining a subscriber's profile; and (3) the HLR sends a qualification directive to a serving MSC, with the updated or modified profile of the subscriber. By using the improved HLR of the present invention, a carrier may have the HLR bypass the fraud protection processing in areas that support authentication processing to provide convenience to the subscribers so that they do not have to enter their PINs to use their cellular phones.

Abstract: A remote controlled lock system (100) includes a computer (111), a system controller (102), a transmitter (109), and at least one remote controlled lock device (105). The system controller (102) generates one of a digital lock or unlock code upon a change of a user access condition of the computer (111). The transmitter (109) transmits a radio signal including the lock code or the unlock code, and a selective call receiver address. The remote controlled lock device (105) includes a selective call receiver (310) and an electromechanical lock (311). The electromechanical lock (311) has a locking member (1205) which is switched to a mechanically stable lock or unlock position in response to the lock or unlock code when the radio signal when the transmitted selective call receiver address matches a predetermined address stored in the selective call receiver (310).

Abstract: A logic circuit (260) includes recursive elements (470, 1070, 1400, 1600) interconnected in a matrix (300), and M data inputs (490), and a logic circuit output (475). In one embodiment, N+1 binary column setup inputs (485), and M-N binary row setup inputs (480) are also included. The matrix (300) is an arrangement of the recursive elements (470) in rows, columns, and diagonals. The M data inputs (490) are for coupling the M bits of the binary word to the recursive elements (470). The logic circuit output (475) includes an output (810) of one of the recursive elements (470, 1070, 1400, 1600). The logic circuit output (475) has a binary value determined by a comparison of the number of bits having a first binary value within the binary word, to the predetermined number, N. In the one embodiment, the comparison is determined by the values of the setup inputs (480), (485).

Abstract: In a communications system utilizing binary messages, a modulator for differentially modulating the messages, i.e. a change in the differentially encoded data is produced for every "one" in the data stream and no change occurs for every "zero" in the data stream, the differentially encoded data is modulated by a square wave signal having a predetermined number of cycles per bit of information, and the output is passed through a band pass filter to remove a substantial portion of the upper side band, and the DC. In the demodulator the modulated, differentially encoded message is applied to one input of an exclusive OR and the same message is delayed one bit and applied to a second input of the exclusive OR to remove the modulation and differential encoding, after which the message is integrated and shaped to place the message in the original binary form.
