摘要： There is elucidated a method of communicating data packets (210; 520) within a data communication network (10). The network (10) comprises communication nodes (30a, 30b, 30c, 40), wherein a first nodal set (30a, 30b, 30c) comprises nodes which are operable to communicate via a communication medium with a second nodal set (40) comprising at least one of said nodes (30a, 30b, 30c, 40). The method comprises steps of: (a) mutually synchronizing together two or more nodes of said first nodal set; and (b) simultaneously in a synchronized manner transmitting one or more data packets from the mutually synchronized two or more nodes of said first nodal set via said communication medium for substantially simultaneous reception at said second nodal set (40). The network (10) is susceptible to being simpler to implement in comparison to comparable contemporary communication networks, as well as potentially providing a better quality-of-service (QoS) especially when handover from one access point node to another is considered.

摘要： The present invention provides a 3D handwriting recognition system that allows users to freely write words or characters in a 3D space in a touchless manner, without requiring any physical medium such as a pad or a tablet. The users' handwriting input in a 3D space will be tracked by an input device of the system that generates corresponding 3D motion data and wirelessly transfers the 3D motion data to a recognition device of the system. The 3D motion data will be converted and then mapped onto a 2D plane to generate corresponding 2D images for handwriting recognition. In this way, the users' inputting will never be limited to any screen, pad or plane, and the users will have more flexibility and enjoyable writing experience.

摘要： A wireless network employs at least a base station (1 to 3) and a plurality of assigned terminals (4 to 14) for exchanging user data and control data. That base station (1 to 3) includes a device (21, 22) for correlating a signaling sequence transmitted by at least one terminal (4 to 14) to indicate the wish to use a contention channel and for detecting the pulse evolved from a received and correlated signaling sequence. After a signaling sequence has been detected, the base station (1 to 3) transmits a provision message over a contention channel to be utilized by the assigned terminals (4 to 14).

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 takes the advantage of the WLAN resources in hotspots for voice and data connections and enables seamless handover between WWAN and WLAN and vice versa. This allows two users in the hotspots to communicate with each other by making a voice over IP (VoIP) or video call, thus achieving cost savings for the end users and WWAN resources savings for the wireless operators. According to one embodiment of the invention, a mobile terminal has wireless wide area network (WWAN) and wireless local area network (WLAN) interfaces. The mobile terminal via a WWAN. If a WLAN is present, the mobile terminal sends a handover request together with its network address to the called mobile terminal, using a short message service (SMS) technique or a watermarking technique, for initiating a WLAN call with the called mobile terminal via a WLAN. After the WLAN call is established with the called mobile terminal, the mobile terminal releases the WWAN call.

摘要： Interference cancellation in a mobile terminal (4) in telecommunication systems like Direct Sequence-Code Division Multiple Access systems or DS-CDMA systems can be improved by providing the mobile terminal (4) with a multi-user detector (41,42,43). These multi-user detectors require the spreading codes of other mobile terminals (2,3,5,6,7,8,9), which spreading codes are available in base stations (1) and thus need to be sent to said mobile terminal (4). By further transmitting power information of other mobile terminals (2,3,5,6,7,8,9) to the mobile terminal (4), a selector (52) can make an intelligent selection in said mobile terminal (4) and select the most important spreading codes thereby reducing the computational complexity. By locating a selector (22) in a base station (1), an intelligent selection can also be made in said base station. Preferably a selection is made per antenna sector and/or in dependence of antenna sectors, in which case direction information of other mobile terminals (2,3,5,6,7,8,9) need to be used.

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.
摘要翻译：集中控制的无线网络需要中央控制器与无线网络内的每个站之间的可靠通信。无线网络的结构通常是动态的或临时的，因为台站进入和离开网络，或者被物理地迁移。网络的中央控制器的选择也可以是动态的，这是因为当前的中央控制器希望退出网络，或者因为当前中央控制器与一个或多个站之间的通信差。本发明公开了一种用于评估网络中所有站之间的通信路径的质量的方法和装置。该评估作为对网络质量的连续监视是有用的，并且可以用于基于到达和来自该站的通信路径的质量来选择替代的中央控制站。此外，可以根据需要利用质量评估来建立中继通信路径。

摘要： The invention relates to a local area network comprising a plurality of sub-networks and a plurality of bridge terminals, which bridge terminals are each provided for transmitting data between the terminals of a at least two sub-networks via a wireless medium. Once it has been put into operation, a bridge terminal determines the sub-networks that can be reached and establishes a list of groups that have each n elements as an identification for the sub-networks, from all the m sub-networks that can be reached, where m>n and n>1. The groups in the list are sorted according to a predefined criterion. The bridge terminal then connects the sub-networks whose identification occurs in the first group of the sorted list.
