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.
摘要翻译：本发明提供能够管理对等（P2P）通信的无线通信系统。在本发明的一个实施例中，系统在接收到发起呼叫的请求时，确定是否可以在两个移动终端之间建立P2P通信。该系统还确定用于P2P通信的两个移动终端的操作模式。如果可以在两个移动终端之间建立P2P通信，并且两个移动终端处于用于P2P通信的默认模式，则系统在两个移动终端之间建立P2P通信。另一方面，如果移动终端中的任何一个处于提示模式，则系统在提示模式下向移动终端发送提示，以及关于使用P2P通信服务的激励的信息。如果移动终端的用户在提示模式下选择P2P通信业务，则系统分配用于在两个移动终端之间建立P2P链路的资源。在P2P通信完成之后，系统向移动终端发送打折的计费信息。

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： 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.
