Abstract: A system, method, security gateway and computer program product are provided for creating and maintaining a centralized key store. The system includes a first security gateway and a second security gateway. The first security gateway is capable of applying a security service associated with an application instance identifier to at least one packet of data to thereby transform the at least one packet of data. In this regard, the first security gateway can apply the security service to the packet based upon at least one security policy and at least one security association. The second security gateway, in turn, is capable of applying the security service associated with the application instance identifier to the transformed packet of data to thereby generate a representation of the packet of data.

Abstract: A method is disclosed for operating a RF receiver of a communications equipment, as is circuitry for implementing the method. The method includes, while operating under the control of a data processor of the communications equipment, generating a calibration signal; injecting the calibration signal into a low noise amplifier (LNA) of the RF receiver; measuring a downconverted response of the receiver at a plurality of different frequencies of the calibration signal, or measuring the downconverted response of the receiver at a plurality of different LNA tuning combinations using a fixed calibration frequency, and at least one of tuning a resonance frequency of at least one LNA resonator based on the measured downconverted response so as to compensate at least for variations in component values that comprise the at least one resonator, or adjusting the linearity of the receiver.

Abstract: A mobile station is constructed to include a transceiver comprising a transmitter circuit having a transmit RF filter that passes a transmit band of frequencies that is partitioned into transmit frequency channels and a receiver circuit having a receiver RF filter that passes a receive band of frequencies that is partitioned into receiver frequency channels. Also included is an antenna coupled through a duplexer to an output of the transmitter circuit and to an input of the receiver circuit. The mobile station further includes circuitry, responsive to a currently selected RF channel, for compensating for a non-ideal operation of the RF filters and the duplexer over a full bandwidth range of the transmit and receive frequencies. The compensating circuitry compensates for RF filter operation in a transmit RF channel that is nearest to the band of receive RF frequencies and/or compensates for RF filter operation in a receive RF channel that is nearest to the band of transmit RF frequencies.

Abstract: A method and an apparatus for improving the image quality. The method comprises steps of producing image correcting information to decrease errors in the image to be produced by a camera module (109, 111, 112) by comparing the image taken by said camera module (109, 111, 112, 113) with a test image, storing the image correcting information produced and identifying information related to said image correcting information in the memory of an electronic peripheral device (104, 106), receiving the image produced by said camera module (109, 111, 112, 113) and a second piece of identifying information related to said image in the electronic peripheral device (104, 106), comparing said identifying information with said second piece of identifying information in said peripheral device, and performing an image improvement operation on said image in said peripheral device in response to the comparison carried out.

Abstract: A method and an apparatus are described for increasing the flexibility of uplink resource allocation for a mobile station (MS) (100), that is backwards compatible with earlier standards that provide only a single data flow per MS. The method includes steps of (A) associating an allocated uplink resource (an Uplink State Flag (USF)) with one or more Temporary Block Flows (TBFs) for a Packet Data Channel (PDCH), and not with a MS per se (although a given USF is associated with only a single MS) ; and (B) using a Temporary Flow Identity (TFI) for identifying a TBF, where a TFI may be unique to a PDCH and, if not, is unique with respect to the MS on a PDCH (and hence with respect to the USF). The result is that the MS is enabled to send any of its TBFs on allocated resources of the same PDCH. An uplink resource may be allocated to the MS dynamically using the Uplink State Flag (USF) or by using a fixed allocation. A total of n Radio Bearers are associated with a single TBF, where n≦1.
