Abstract: A system and method for a novel broadcasting scheme (NBS) in a wireless local area network are described, which can operate with or without a network connection. The system permits transmission of application-specific data through a specific field in a beacon frame, the Service Set Identity (SSID). By implementing a NBS Processor in an AP and a NBS Parser in stations, the AP can broadcast application-specific data while the stations can automatically act upon the receipt of the broadcast.

Abstract: An Ad-Hoc wireless network according to the present invention employs a TDMA based neighbor discovery protocol, where each network node is assigned a unique time slot to broadcast neighbor discovery packets or messages. A primary controller node is dynamically designated to perform the time slot assignments. A dynamic selection of a secondary or backup controller node is further provided in case of failure of the primary controller node. The present invention further includes flooding techniques based upon TDMA. A TDMA HELLO flood is used to distribute a small number of common parameters to network nodes by placing or piggybacking the information within the neighbor discovery messages. A CNR flood is based on the principles of a RAKE type receiver and used to distribute time slot assignments to the entire network.

Abstract: A computer and a method for enabling remote communication to a computer operating in a power-saving mode in which one or more one power sources to internal devices are disabled. The computer is equipped with a power management control circuit which is responsive to a first signal indicating that a device used to receive remote communication is to receive power while operating in a power-saving mode. In the event that a remote communications is detected which is targeted for the computer, a second signal is asserted by the remote communications device. The power management control circuit responds by exiting the power-saving mode and restoring power to the disabled power source to enable the computer to process the incoming communication. The remote communication may be through a wireless source such as a radio frequency channel or through a fixed wire such as a telephone network or LAN.

Abstract: A system and method for performing ranging and positioning as follows by using the procedure for packet transmission and reception between a sender and a recipient. A first radio set transmits packets to a second radio set as a recipient. The second radio set returns the packets without fail after the lapse of time (from the detection of packets) which corresponds to an integral multiple of a prescribed unit time. The first radio set counts, by using its counter, the time which has elapsed from its transmission of packets to its detection of packets from the second radio set. The remainder of the thus counted time after subtraction of the time taken by the second radio set from packet detection to packet return and the processing time of the first radio set itself is converted into the distance of propagation between the first radio set and the second radio set as a recipient.

A physical layer connection is established with the base station on the assigned subchannel. The physical layer connection corresponds to the physical layer. The method further includes releasing the assigned subchannel so that the physical layer connection is terminated, and maintaining a state of at least one other layer during the communication session after termination of the physical layer.

Abstract: The code extraction unit extracts time information from a time signal. The block determination unit determines whether the extracted time information is correct by each kind of the time information. The time information collection unit collects time information determined as correct. The time information determination unit performs logic check of the collected time information, and determines whether correct information is collected for all kinds of the time information, and if not collected, stores time information determined as logically correct in a temporary storage unit. If correct information is not collected for all kinds in the time information collection unit, a time information modification unit updates the time information in the time information collection unit by the time information stored in the temporary storage unit. If correct information is collected for all kinds of the time information, the time information determination unit corrects time information retained in a timekeeping unit.

Abstract: When a cell phone fails in location registry to a base station, it removes the base station from a candidate group. Then it searches for and captures, for the next location registry, a base station whose pilot signal has the highest electric field intensity among the updated candidate group. When the registry is yet to be successful, the cell phone prohibits the location registry with maintaining an idle (waiting) state. Here, the pilot signals are observed among the candidate group. When a certain base station whose pilot signal exceeds a preset level of electric field intensity is detected, the idle handoff to the certain base station is executed. This success of the idle handoff then resumes the location registry to the certain base station.

Abstract: An apparatus, system, and method are provided for locating a transceiver using RF communications and radio services. The apparatus, system, and method include a transceiver that receives an RF signal, decodes a serial number, and responds by transmitting either a low power signal with a unique identification code and location information, or a high power signal with a station identifier received from the RF signal and location information. The high power signal is transmitted in response to a licensed radio operator (such as a HAM, police, etc.) and is transmitted using the licensed radio operator's station identifier. Since the licensed radio operator is the control operator, the current invention may be owned and operated by the general public without a special license. The current invention allows a mobile transceiver to provide a greatly expanded transmission range that enhances the probability of locating the transceiver.

Abstract: A geographical web browser allows a user to navigate a network application such as the Word Wide Web by physically navigating in geographical coordinates. For example, a geographical web browser is implemented in a mobile unit such as a dashboard computer. The mobile unit includes one or more transducers such as antennas and is operative to receive locally broadcast signals or to operate a global positioning system (GPS) receiver. As the mobile unit navigates into different physical localities, different web pages are displayed by the geographical web browser. For example, a user desiring to buy a house can set the web browser to a real estate web page. Instead of clicking on a hyperlink to access web pages of properties in an area, the user drives into a first area and automatically receives web pages relating to homes in that area. When the mobile unit crosses town and enters a second area, a new set of web pages is downloaded relating to properties in the second area.

Abstract: An assignment section 101 determines communication resource assignment to communication terminals based on a transmission rate at which communication is possible for each subcarrier of each communication terminal, and instructs a buffer section 102 to output forward transmission data. In addition, the assignment section 101 instructs a frame creation section 103 to perform forward transmission data symbolization, and also outputs a signal indicating communication resource assignment to each communication terminal. The buffer section 102 holds forward transmission data, and outputs forward transmission data to the frame creation section 103 in accordance with instructions from the assignment section 101. The frame creation section 103 symbolizes a resource assignment signal and transmission data to create a frame, which it outputs to a spreading section 104.

Abstract: Apparatus, and an associated method, for facilitating concurrent effectuation of more than one packet data communication session at a mobile node. Both a normal packet data communication session and, for instance, an IOTA provisioning session are concurrently performed. A second packet data session initiator initiates the communication session through generation of a registration request. A communication session is formed, and a communicator communicates pursuant to the communication session, concurrent with performance of the first packet data communication session. Because both communication sessions are concurrently performable, one or the other of the communication sessions need not be terminated to permit the other of the communication sessions to be performed.
