Abstract: The invention provides a route updating method which reduces the flow rate of updating notifications, which are circulated in a network, to improve the scalability. A micromobility network includes routers connected in a tree connection and radio base stations connected to the routers in the lowest layer such that an updating notification of a route from a mobile terminal is repeated in order from a radio base station to successive higher order routers to update the route and a packet is distributed along the updated route. In the mobility network, directly lower order routers to each router are numbered to the numbers 1 to n with reference to the direct lower order router accommodation number n, and a route from the radio base station to the router in the highest layer represented by a route number composed of the numbers of the thus numbered routers is applied to the radio base station.

Abstract: A system, methods, an area register and a service center for transmitting point-to-multipoint services to a geographical destination area that can be indicated by using a logical name. Logical names must be mapped to distribution addresses. The system therefor comprises memory means (AR) for mapping each predetermined logical name (71) to one or more network element addresses (72,73) of the system. In addition, the system comprises one or more service centers which are arranged to inquire, in response to a received service request, the memory means (AR) for the addresses (72, 73) of the network elements corresponding to the logical name (71) of the destination area and to transmit the point-to-multipoint service to the geographical destination area via the network elements. The service is transmitted to cells in conventional manner via network nodes, while a service request is transmitted to other service centers.

The method includes the steps of receiving voice data over the internet protocol connection at the wireless device, sending other voice data over the internet protocol connection from the wireless device, differentiating the voice data from non-voice data and non-data, differentiating the other voice data from other non-voice data and non-data, and controlling the broadcast of the voice data, and the other voice data.

Abstract: A cable retractor assembly is capable of retracting a cable onto a rotatable reel, the rotatable reel being urged to rotate in a predetermined direction by a biasing force. A moveable actuator when located in a first position is capable of overcoming the biasing force that urges the cable to be wound onto the reel. When the moveable actuator is in a second position, the moveable actuator does not impede the biasing force The retractor assembly may be integrated into or detachably secured to a portable electronic device. A sensor within the cable retractor assembly can detect when the reel rotates or the cable is extracted and thereby signal a coupled communications device to pick up an incoming call. The cable retractor assembly further comprises a pick-up actuator that when actuated signals a coupled communications device to pick up an incoming call.

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 and roaming through coverage areas of cellular base stations, wireless LANs, microcells, and other such broadcast domains. A mobile unit communicates with a network server via an air interface that supports wireless packet data. A packet filter filters local hotspot push messages to see whether they coincide with the user's preferences. In some embodiments, the push message is used to notify the user that information is available for download, and in other embodiments the push message provides the content directly to the user.

Abstract: Disclosed is a method for deriving accurate global positioning satellite (GPS) timing by calibrating frame boundaries to GPS timing. Time calibration is achieved by determining a time difference ?t between a reference GPS time (or pulse) and an nth frame boundary. The time difference ?t and a frame boundary identifier specifying the nth frame boundary are provided to a device equipped with a full or partial GPS receiver so that the GPS equipped device may synchronize itself to GPS timing. Upon synchronizing itself to GPS timing, the GPS equipped device may search for GPS signals using information provided by a geographical location server, e.g., WAG server.

Abstract: A service searching system for searching a service in a distributed system comprises a wireless server device and a wireless terminal device. The wireless server device is connected to a network and implements a master search service. On the other hand, the wireless terminal device implements a slave search service, and is capable of communicating with the server by wireless and utilizing the master search service. Besides, the wireless terminal device comprises a storage means that caches service objects obtained through the master search service. In addition, in searching the slave search service for a service, the wireless terminal device begins by searching the service objects cached in the storage means. In the case where the service is not detected, the wireless terminal device searches the master search service. The service objects are cached by being related to priority data.

Abstract: Accurate position capability can be quickly provided using a Wireless Local Area Network (WLAN). When associated with a WLAN, a wireless device can quickly determine its relative and/or coordinate position based on information provided by an access point in the WLAN. Before a wireless device disassociates with the access point, the WLAN can periodically provide time, location, and decoded GPS data to the wireless device. In this manner, the wireless device can significantly reduce the time to acquire the necessary GPS satellite data (i.e. on the order of seconds instead of minutes) to determine its coordinate position.

Abstract: The invention links or associates commands supported by application programs in the wireless device or by the platform itself to remote devices or to other application programs or similar processes by means of a software mechanism referred to as a bus. The commands can be any that a user could initiate manually or that the platform could receive from a remote device or an application program or other process.

Abstract: A framework and method for quality of service (QoS) aware resource discovery in mobile ad hoc networks are presented. Self-organized discovery agents manage the directory information that describes the network resources available for use by clients. In one embodiment, hash indexing of available resources is utilized. The discovery agents also partition the network into domains and collect intra- and inter-domain QoS information. This information is used to allow clients to select appropriate resource providers. This framework and method has low discovery latency and cost in terms of the number of packets for each resource discovery query.

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.
