Patent number: 6108519Abstract: A mobile communications system includes a service-providing base station for providing down-link communication to the mobile station to transmit broadcast service data to a mobile station. In a switch device of the mobile communications system, it is determined whether the mobile station can communicate with the service-providing base station based on available base station information received from the mobile station. The available station information indicates an available base station with which the mobile station can communicate. The mobile station is instructed to change a receive channel to a down-link channel of the service-providing station when the mobile station can communicate with the second base station.Type: GrantFiled: April 24, 1998Date of Patent: August 22, 2000Assignee: NEC CorporationInventor: Yoshio Nitta

Patent number: 6108530Abstract: A system (100) that is capable of transmitting a displayable message to a short message entity (102, 104 or 105) in more than one data package over a conveying network. The system (100) uses a capacity determiner (206) to determine a capacity of the conveying network for transmitting data. Based on this capacity of the conveying network, a fragmenter (204) divides the displayable message into fragments at an application protocol layer. The size of a fragment does not exceed the capacity of the conveying network. Finally, a packager (208) packages the fragments into data packages. The data packages are operable to be separately transmitted by a short message service over the conveying network. The data packages may include a reference parameter corresponding to the position of the fragment in the displayable message. Further, a reference parameter may indicate the total size of the displayable message being fragmented and packaged.Type: GrantFiled: December 14, 1995Date of Patent: August 22, 2000Assignee: Lucent Technologies Inc.Inventors: Benson S. Ayabe, Sharat Subramaniyam Chander, Semyon B. Mizikovsky

Patent number: 6108549Abstract: A method and apparatus for passing network device operations between a source and a target network device which are associated with a mobile communication unit in a radio communication system is provided. This passing of network device operations is accomplished by converting a first form of information to a second form in the source network device. Subsequently, the source and the target network device are notified that operations associated with the mobile communication unit will be passed at a particular time. At that particular time the information converting is bypassed such that the first form of information is provided to the target network device. In addition, the target network device begins to monitor incoming information for the first form of incoming information. In response to a presence of the first form of incoming information at the target network device, the first form of information is converted into the second form in the target network device.Type: GrantFiled: August 12, 1997Date of Patent: August 22, 2000Assignee: Motorola, Inc.Inventor: Jeffrey D.

Patent number: 6094584Abstract: A method for operating a wireless telecommunications system whereby communication channels are efficiently allocated to cells of the system is provided. In accordance with an illustrative embodiment of the present method, call demand information is obtained for each cell in the wireless system and converted to a channel demand. Once the channel demand for each cell is known, a tentative channel allocation is performed. Call demand information can be obtained as frequently as desired to update channel allocation throughout the wireless system. In some embodiments, the method for channel allocation described herein can be used alone to allocate channels. In other embodiments, the present method for channel allocation can be used on an hourly, daily, or other temporal basis, as appropriate, to provide a channel allocation which is then updated on a substantially continuous basis by any conventional dynamic channel allocation scheme.Type: GrantFiled: March 26, 1998Date of Patent: July 25, 2000Assignee: Lucent Technologies, Inc.Inventors: Sanjeev Khanna, Krishnan Kumaran

Patent number: 6085083Abstract: 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.Type: GrantFiled: January 11, 1997Date of Patent: July 4, 2000Assignee: Tandem Computers, Inc.Inventor: James A.

Patent number: 6070070Abstract: A command, such as an application specific command, is communicated from a central host to a remote station via a cellular mobile radio network. The station may be a fixed or roaming device. The central host sends the command a network switch, such as an SS7 SSP, wherein the command comprises a mobile identification number (MIN) and an electronic serial number (ESN). The network switch queries an associated HLR database to locate the remote station, the query specifying the MIN and the ESN. If the HLR does not recognize the MIN/ESN combination, it so informs the network switch, as well as the VLR associated with the MSC serving a remote station identified by the ESN. In response to the notification from the HLR, the VLR removes any entry in its database relating to the ESN and updates its database with the new MIN/ESN combination transmitted by the HLR to the VLR.Type: GrantFiled: January 20, 1999Date of Patent: May 30, 2000Assignee: Aeris.netInventor: Christoph Karl Ladue

Patent number: 6064874Abstract: A mobile telephone, or personal communication services subscriber who wishes directory assistance services is connected in the conventional manner to an operator who identifies a destination telephone number desired by the subscriber. As known in the prior art, the operator then initiates a call connecting the subscriber to the destination telephone number. In a preferred embodiment, the operator locates a desired destination telephone number in a computer database, and can select automatic dialing of the located number. Further, rather than dropping all further involvement with the call, the preferred embodiment of the present invention continually monitors the connection thereby established for a predetermined DTMF signal issued by the customer, such as that obtained by pressing the "*" button. If such a signal is detected, the customer is transferred to a directory assistance operator, who can then provide whatever further assistance is needed (e.g., providing further directory assistance).Type: GrantFiled: February 12, 1999Date of Patent: May 16, 2000Assignee: Metro One Telecommunications, Inc.Inventors: Patrick M.

Patent number: 6058295Abstract: A tuning circuit which has a wide tuning bandwidth. The tuning bandwidth or the tuning frequency can be easily changed. The tuning circuit 1 is imposed of two cascade-connected tuning amplifier sections 2 and 3. Each of the sections 2 and 3 is provided with cascade-connected phase-shifting circuits 10C and 30C, a non-inverting circuit 50, a voltage dividing circuit 160, and an adding circuit composed of a feedback resistor 70 and an input resistor 74. Prescribed tuning operation is performed by shifting the prescribed frequency 360.degree. by means of the phase shifting circuits 10C and 30C and setting the open loop gain of a feedback loop at less than 1 when the output of the voltage dividing circuit 160 is feedback. The resistance ratio between the feedback resistor 70 and the input resistor 74 of each section 2, 3 is adjusted so that the maximum damping of each section 2, 3 may become smaller and the tuning bandwidth of each section 2, 3 becomes wider.Type: GrantFiled: June 23, 1997Date of Patent: May 2, 2000Assignee: Takeshi IkedaInventors: Takeshi Ikeda, Tadataka Ohe, Tsutomu Nakanishi
