摘要： The present invention provides a wireless communication system capable of managing multi-hop communications. In one embodiment, upon receiving a request from a mobile terminal for initiating a call, the system determines whether the mobile terminal can use multi-hop communication services and its operating mode for multi-hop communication. The system also determines whether relaying can be provided by other mobile terminals. Then, the system will establish multi-hop communication between the mobile terminal and the system based on the operating mode of the mobile terminal. In a default mode, multi-hop communication can be established without the user's knowledge. In a prompt mode, however, the system sends a prompt to the mobile terminal for selection of the multi-hop communication services, along with information about incentives for using the services. After the multi-hop communication is completed, the system records information relating to the multi-hop communication services for the originating and relaying mobile terminals in the HLR/VLR.

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 time reference point can be determined in a radio system by sending a synchronization sequence s(i), i=0, . . . N−1, from transmitter X, 40 to receiver Y, 48, and by detecting the peak value at the output of a matched-filter, 44, h(i)=s(N−1-i) on Y. In practical systems the accuracy of this peak detection is limited by interference and noise on the radio channel. To increase the peak detection accuracy, we propose to repeat the transmission of the same synchronization sequence K times. The interval L between repetitions is constant and the amplitude of the synchronization sequence in each repetition varies according to a given variation pattern a(jL), j=0, . . . , K−1. The receiver Y, 48 knows L and a(jL), j=0, . . . , K−1. After comparison to a threshold, the matched-filter 44 at the receiver 48 may deliver peaks resulted from repeatedly received synchronization sequences or peaks caused by interference and/or noise.

摘要： The invention relates to a wireless network which includes a plurality of network nodes, each of which includes a radio device with a respective radio clock supply and is arranged to exchange data via a wireless medium, and also includes a user interface for the exchange of data between the associated radio device and at least one user. At least one user of a network node receives a user clock, being independent of the radio clock, from a user clock supply of the relevant network node. Each network node is arranged to determine, in response to events specified by a central network node, a time value related to the relevant application clock. The central network node transmits at least the last time value formed by a selected network node. Each network node forms the difference between the last two time values determined and synchronizes the frequency of its user clock supply in dependence on the comparison of the difference between its last two time values determined with the difference between the last two time values of the selected network node.
