摘要： A method is disclosed for routing packets in an intermediate node between a mobile node and a correspondent node in a packet-switched network, only one of said nodes being macro-mobility enabled, comprising at the intermediate node: —exchanging lower-layer-address-update-related messages with said macro-mobility enabled node; —mapping source address, destination address and potentially protocol parameters of lower-layer packets exchanged between the mobile node and the correspondent node in such a way that the macro-mobility enabled node can communicate with the other node as if the other node is also macro-mobility enabled, and such that the other node can communicate with the intermediate node as if the intermediate node is a non-macro-mobility-enabled node. Also associated devices, update methods for devices, and servers are disclosed.

摘要： At least one base station of a wireless network adjusts its access area so as to drive at least one measure of utilization of a resource or resources of that cell toward, but not to exceed, a specified maximum level. The adjustment is dynamic in that it responds in real time to traffic fluctuations. The adjustment is autonomous in that it is not directed from outside the cell. The access area of the cell is determined by the received strength, at the respective users, of a beacon channel transmitted from the base station. In specific implementations, the access area may be adjusted by adjusting the effective signal transmit strength of the beacon signal, or by adjusting the tilt of the antenna that transmits to the cell.

摘要： Location-based services are provided in a communication system comprising at least a portion of at least one wireless network. In one aspect of the invention, particular ones of a plurality of mobile user devices associated with a wireless network are identified for which sufficient location-indicative information is available from which a general location of said devices can be inferred without performing actual location measurements for said devices. The delivery of location queries to the identified mobile user devices is prevented, such that a number of location queries required for provision of a given location-based service is reduced relative to a number of location queries which would otherwise be required without the delivery prevention.

摘要： Techniques for determination of network parameters in, e.g., a processor-implemented system for characterizing, adjusting or optimizing the performance of a wireless network. In an illustrative embodiment, values of one or more link parameters of the wireless network are interpolated along edges in a mesh of data points derived at least in part from road location data characterizing an area serviced by the wireless network. A measure of network performance, e.g., a coverage measure based on pilot signal-to-interference ratio, may be generated using the interpolated values. The edges of the mesh have associated therewith a set of edge weights representative of traffic in the wireless network. The edge weights may be adjusted so as to be in agreement with available network traffic data. Interpolating between the data points of the road-based mesh permits the network performance measure to be computed as a smooth, differentiable function of the one or more link parameters, thereby simplifying network characterization, adjustment and optimization.

摘要： The invention is a device that provides a phase-tunable antenna feed network that allows beam-steering and beam-width variation with simple actuation, at low cost, and with high rf performance. The device provides a series-feed where signal power splitters and phase-shifters are alternately disposed in series. Each phase-shifter consists of reflection-mode phase-shifter elements that operate in conjunction with an isolation device. This avoids the critical resonance condition between periodically aligned phase-shifters over the entire tuning range, since the isolation devices can easily be matched and/or aligned with non-resonant spacing. The main feed-line interconnections have the same impedance, thereby enabling the utilization of the same phase-shifter design for the entire network. Moreover, a common driving mechanism can be used for the phase-shifters to steer the antenna beam. Splitting the array into two sub-arrays with individual collective driving mechanism further allows beam-width variation by steering the beams of both sub-arrays in opposite directions. The device is further compatible with symmetrical series network designs that have better frequency response. The series feed network preferably uses a phase-shifter for shifting a signal propagating through a transmission line by moving a conductive construct between an active line and a ground plane of the transmission line. The conductive construct capacitively couples with either the active line and/or the ground plane, forming a capacitive shunt that reflects a significant part of the signal. The remaining portion of the signal is reflected at a terminated end of the transmission line, resulting in substantially no signal loss.
