Abstract:
A base-site (304) combines baseband frequency hopping and fast-synthesizer hopping to produce an economical frequency hopping communication system (300). The base-site (304) combines the fast-synthesizer frequency hopping capability of transmitters (307-309) with baseband frequency hopping to produce a frequency hopping communication system (300) which serves the same number of subscribers served by transmitters (208-213) in a purely baseband hopping communication system (200), but with fewer transmitters (307-309). The implementation of frequency-selective cavities (312-317) having very low loss eliminates the need for wideband hybrid combiners (112-114), which in turn eliminates transmitted-signal power loss experienced in a purely fast-synthesizer frequency hopping communication system (100).
Abstract:
A method in a wireless communications network connected to a packet network including receiving (410) at a packet server handover information, e.g., neighbor measurements, from a wireless communications device, negotiating (420) with the radio communications network, e.g., with a base station controller, for a radio resource transfer for a mobile wireless communications device, and sending (440), from the packet server, radio resource information to the mobile wireless communications device.
Abstract:
A method and system of generating neighbor cell lists in a cellular environment having a first cell (cell D) (116) and a plurality of neighbor cells (cells C, E, F, and G). The first cell and the neighbor cells each include a plurality of designated active controllers associated therewith. In one embodiment, one of the controllers (RNC3) (118) in the first cell is designated as the active controller for the first cell, a first neighbor list of the active controllers (RNC1, RNC3, RNC4, and RNC4, respectively) for the neighbor cells is generated, and, upon a change in active status of any of the neighboring active controllers, a second neighbor list of the active controllers (RNC2, RNC4, RNC4, and RNC4, respectively) for the neighbor cells is generated. The lists are generated in accordance with a database of controllers link-able with the designated active controller.
Abstract:
A wireless communication system (200, 300, 400, 500) mitigates the effects of excess timing delay caused by varying lengths of communication paths. In one general implementation, a transition communication path (206, 323, 329) is used to transfer a time-advanced version of a timing reference signal so that the cumulative time delay at a transition cell (209, 325, 331) is reduced. In another general implementation, the timing reference signal is time-advanced in all communication paths (403-411), and selected communication paths (403-407) include a time delay means (423-427, 503-507) such that the cumulative time delay at an area (421) near a target coverage area (130) is reduced. By reducing the cumulative time delay at the area (421) near the target coverage area (130), a hand-off of a communication of a mobile station (128) into the target coverage area (130) can be performed.

Abstract:
The need for providing user information to content providers to enable them to authenticate user access to certain content, to perform billing, or to otherwise monitor content use is addressed by embodiments of the present invention. A content delivery server (110) sends service announcement information to user equipment (UE) (101) for a content delivery session of a content provider (120). The service announcement information indicates that user information is requested by the content provider for this session. When the UE user requests to activate the session, the UE obtains the requested user information and sends it with an activation request to the content delivery server. The content delivery server is then able to send the obtained user information, with perhaps additional user information, to the content provider when requesting session activation. The content delivery server activates (subscribes, e.g.) after receiving an indication that activation is approved by the content provider.
Abstract:
Communications are established between an originating mobile station (104) and a target mobile station (120) in an expedited manner. An initial short packet is transmitted from an originating mobile station (104) and the initial short packet is translated into an Internet Protocol (IP) packet. The IP packet is transmitted to a target Packet Control Unit (PCU) (116). An acknowledgment IP packet is responsively received from the target mobile station (120) via the target PCU (116) and a communication link is established between the originating mobile station (104) and the target mobile station (120).
Abstract:
A method (500, 600) and apparatus (200) for handover of a communication device (120) between a first network (130) and a second network (140) while the communication device is in an ongoing communication. The communication device can register with the second network (610). The communication device can also enter an ongoing communication via the first network (620). The communication device can send a transfer request to the second network to request a handover of the ongoing communication between the first network and the second network without interrupting the ongoing communication (640).
