Abstract: A method and device for reducing an input image by modifying the palette used in image compression. The reduction process involves mapping one or more colors of the original palette to a single color in a new palette. The image size of the reduced image is estimated from the entropy of the input image and that of the modified palette. A scaling factor, which can be computed from the image statistics inherent to the input image, is also used for adjusting the estimated image size of the reduced image.

Abstract: Method for compressing a HTTP message, including at least one field name and at least one field value, comprising Receive parsing said HTTP message, to identify said at least one field name and said at least one field value, mapping each field name onto at least one binary octet (byte), the most significant bit (MSB) of said octet being set to “one”, mapping each field values onto at least one binary octet (byte), the most significant bit (MSB) of said octet being set to “zero”, and outputting said binary octets (bytes) to provide the HTTP message in compressed format. The method uses binary tagging instead of complex compression algorithms, making it extremely efficient if the processing power requirements (low) or latency-time (low) is considered.

Abstract: A receiver module 11 comprises a loop antenna 14 for receiving signals from a digital broadcast network 3. The receiver module 11 may be an integral component of, or attached to, a mobile terminal 1 that comprises a cellular transceiver 8. For example, the receiver module 11 may be incorporated in a battery pack and inserted into a battery compartment of the mobile terminal 1, so that the receiver module 11 and mobile terminal 1 are powered by battery 13. The loop antenna 14 is substantially resistant to electric fields produced by the transceiver 8 and other sources, and may be arranged within the receiver module 11. Where an external loop antenna 41 is provided instead of, or in addition to, loop antenna 14, the receiver module 11 may be arranged to monitor the quality of signals received from the digital broadcast network 3 and alert a user to deploy the external antenna 41 if the signal quality is low or decreasing.

Abstract: A method and device are disclosed for reporting capability of a mobile device, in order to improve experiences of the user of the mobile device. This capability reporting is accomplished by a web service that makes available a device profile from a device profile repository located within the mobile device. The web service utilizes reverse hypertext transfer protocol (HTTP) binding for simple object access protocol (SOAP). Enhanced content is subsequently received at the mobile device, such as content in an improved format, and the enhanced content is based at least partly upon the capability of the mobile device disclosed by the web service. If a characteristic of the mobile device changes, thereby causing a modification of the capability of the mobile device for accepting a type of enhanced content, an update signal is sent to the device profile. The device profile is a user agent profile or variation thereof.

Abstract: Apparatus, and an associated method, for facilitating selection of antenna pattern characteristics to be exhibited by an antenna assembly of a communication station, such as a base transceiver station operable in a cellular communication system. Indications of channel conditions on an uplink channel are utilized in the determination of antenna weighting values by which to weight antenna weighting elements of the antenna assembly. In one implementation, an uplink channel correlation matrix is reformulated into vector form to reduce the computational complexity of calculations required to select the antenna weighting values. In another implementation, a discrete Fourier transform operation is performed using fast Fourier transform techniques to select the antenna weighting values.

Abstract: Apparatus, and an associated method, having a packet zone list timer embodied at a mobile node operable in a packet radio communication system. The packet zone list timer provides hysteresis to reduce the possibility of a ping-pong effect when a mobile node is operated at, or crosses, a packet zone boundary. A timer value used by the packet zone timer is selected at the mobile node without the need for network-generated commands to notify the mobile node of the timer value. Comparisons are made at the mobile node, and determinations are made at the mobile node as to whether registration of the mobile node is required.

Abstract: A method and system for processing information data in a wireless communications system for reducing the complexity in spatial multiplexing of signals over different transmit antennas. In orthogonalized spatial multiplexing with the resolution of one, encoded data are interleaved and converted into a plurality of parallel sub-streams. Each sub-stream is then spreaded with a user specific spreading code with an intentional delay offset of few chips prior to modulating the encoded data for transmission. Likewise, in orthogonalized spatial multiplexing with the resolution of two, encoded data are interleaved and converted into a plurality of parallel sub-stream pairs. Each sub-stream pair is spreaded pairwise with a user specific spreading code with an intentional delay offset of few chips.

Abstract: A method is disclosed for operating a device having a numeric keypad to provide intelligent text input for Indian scripts, such as Hindi. In this method predetermined number keys, such as 2 and 3, are reserved for vowels. These keys produce either independent vowels or dependent vowels (matras) depending on the character preceding the text buffer insertion point. If the character preceding the insertion point is a consonant, keys 2 and 3 produce dependent vowels, in all other cases these keys produce independent vowels. If the user wishes to change the dependent vowel into an independent vowel, the user can do this by pressing a context switch key, such as *, and the dependent vowel in sequence. As a result, the vowel is inserted as an independent vowel, thereby overriding the context into which the vowel is being entered. Other number keys, in the preferred embodiment 4,5,6,7,8 and 9, are reserved for consonants. If the user presses any of these keys, a consonant is inserted into the display.
