Abstract: Applications in a broadcast environment distribute events in real-time to a large number of receivers within specified geographic locations while efficiently sharing bandwidth resources with other applications using the same broadcast network. Applications need not be aware of the other applications sharing the resources, nor of the methods, protocols, and other mechanisms used to actually broadcast the data over the broadcast medium. Server-side applications that serve data, send notifications, or distribute events to specific locations within the network use a broadcast location manager. Client applications that receive such data, notifications, or events use a client location filter to obtain events that are relevant based on the location of the device. The broadcast location manager and client location filter work together to reliably and efficiently transmit data, notifications, and events to specific locations over the broadcast network for all applications involved.

Abstract: A distributed multi-channel TDMA MAC time slot and channel allocation algorithm for wireless networks is provided. The time slot and channel allocation includes a distributed allocation phase and an allocation adjustment phase. Each phase begins allocation at a first node and continues node-by-node until the last node in the network. The allocation then reflects back from the last node to the first node.

Nodes that are within range of the wireless network but are not on the path do not initiate resource allocation but instead participate in the resource allocation initiated from other nodes.

Abstract: An object is, when a mobile terminal performs a handover, to more quickly reset a path after the handover and reduce interrupt time (particularly interrupt time of a QoS path) of packet communication. For example, in a state in which a MN 101 has not acquired an address (NCoA) of a new connection destination (AR 109), the MN 101 requests that a QNE (proxy) 123 start a process of establishing a QoS path used when the MN 101 is connected to a new connection destination. The QNE (proxy) makes a resource reservation between the ONE (proxy) itself and a CN 121. As a result, in an upper stream above a QNE (CRN 115), new path information (filter B) is correlated with path information (filter A) used when the MN is connected to an AR 105. Until when the MN uses the actual new CoA and updates the QoS path after movement, the data packet is encapsulated by a proxy node and transmitted based on the path information (filter B).

Each signaling device in receipt of the signal request sends a signal response having a unique ID which is chosen to be characteristically attenuated by the surroundings of the environment. Because the controlling device can only be in one environment at a given time, and given the attenuation characteristics of the signal response from each signaling device, only one signal response will be received by the controlling device in each environment. Location definitions associated with the received unique ID may be used by programming in the controlling device to recall saved devices states, commands sets, macros, and even to dynamically generate commands based on the location information.

Abstract: The present invention relates to an apparatus and method of controlling power of a terminal in a mobile communication system. According to an exemplary embodiment of the present invention, a code division multiple access (CDMA) code is transmitted to a base station to perform an initial ranging process. Then, when a response signal to the transmitted CDMA code is not received from the base station, the initial ranging process is attempted again a predetermined number of times that is set beforehand. When the initial ranging process that is performed the predetermined number of times fails, a status of the terminal is switched to a sleep mode in which the terminal is completely turned off. Then, when the sleep mode ends, only a predetermined functional unit of the terminal that can measure the propagation environment between the terminal and the base station is turned on to measure the propagation environment.

Abstract: Even when transmitted waves of multiple systems become approximately out of phase while diversity transmission is performed in a W-CDMA wireless system, synchronization establishment determination is more adequately performed. In a W-CDMA wireless system 1, even if it is determined in a normal synchronization establishment determination that synchronization cannot be established, when a phase difference in a common channel of a 0-system and a 1-system is within a certain range and a reception quality of the common channel (or a dedicated channel) has reached a certain level, it is determined that the synchronization can be established. Therefore, even when the transmitted waves of the multiple systems become approximately out of phase while the diversity transmission is performed in the W-CDMA wireless system, the synchronization establishment determination can be more adequately performed depending on whether or not communication is possible in an actual state.

A call originating from a circuit-switched network is passed through a gateway computer to a backbone packet-switched network, and then through a second gateway computer to a second circuit-switched network where it terminates. The voice of both the originating party and the terminating party is converted to data packets by the near-end gateway computer and then converted back to voice by the far-end gateway computer. In an alternative scenario, the originating party uses a computer on the packet-switched network, which replaces the originating circuit-switched network, and the originating computer.
