摘要： The invention relates to a wireless network defined as a group of wireless terminals and an assigned central station. After receiving requests for the wireless transmission of packets between a transmitting and a receiving terminal during a time multiplex frame, the central station assigns time slots within a following time multiplex frame for the transmission of packets from transmitting to receiving terminals. After reception of all the transmission requests, the central station determines a first subset of the group that intend to transmit to receiving terminals, and a second subset containing all transmitting terminals (of the group) that are not contained in the first subset. An order in which the transmitting terminals of the first subset will transmit is determined in accordance with the decreasing number of receiving terminals assigned to each transmitting terminal. The receiving terminals of the first subset are subdivided into a first group, and into a second group where the second group contains all the receiving terminals not contained in the first group, and the receiving terminals of the second group are selected for reception first in time.

摘要： Centrally controlled wireless networks require reliable communications between the central controller and each of the stations within the wireless networks. The structure of a wireless network is often dynamic, or ad-hoc, as stations enter and exit the network, or are physically relocated. The selection of the central controller for the network may also be dynamic, either because the current central controller desires to exit the network, or because the communication between the current central controller and one or more of the stations is poor. This invention discloses a method and apparatus for assessing the quality of the communication paths among all stations in the network. This assessment is useful as a continual monitor of the quality of the network, and can be utilized to select an alternative central control station based upon the quality of communication paths to and from this station. Additionally, the quality assessment can be utilized to establish relay communication paths, as required.

摘要： The present invention provides a wireless communication system capable of managing peer-to-peer (P2P) communications. In one embodiment of the invention, upon receiving a request for initiating a call, the system determines whether P2P communication can be established between the two mobile terminals. The system also determines an operating mode of the two mobile terminals for P2P communication. If the P2P communication can be established between the two mobile terminals and both mobile terminals are in a default mode for P2P communication, the system establishes P2P communication between the two mobile terminals. On the other hand, if any one of the mobile terminals is in a prompt mode, the system sends a prompt to the mobile terminal in the prompt mode, along with information about incentives for using P2P communication services. If the user of the mobile terminal in the prompt mode selects the P2P communication services, the system allocates resources for setting up a P2P link between the two mobile terminals. After the P2P communication is completed, the system sends discounted billing information to the mobile terminals.

摘要： A wireless network is disclosed including at least one base station and a plurality of assigned terminals for exchanging user data and control data. The base station is arranged for transmitting the start time of at least one signaling sequence of at least terminal. For evaluating the signaling sequences transmitted by the terminals, the base station includes a device for correlating a received signaling sequence and for detecting the pulse evolving from a received and correlated signaling sequence.

摘要： The invention relates to a wireless network with several network nodes which each comprise a radio device and of which one forms a transfer network node which is designed for the transmission of data between at least one concealed network node and all other network nodes. One of the network nodes forms a central network node for the control of the radio traffic. The central network node is designed for transmitting frame synchronization data for the formation of frames used in each radio device. The transfer network node serves for the exchange of certain data of the central network node with the concealed network node. The central network node is designed to carry out the exchange of the data between the transfer network node and concealed network nodes as regards the assignation of a sub-frame lying within a frame.
