Abstract: The present invention is directed at a method and system for upgrading existing firmware on third party hardware. The system initially receives identification information along with a firmware version indicator from the third party hardware. The identification information is then used to obtain a stored firmware version indicator representing the expected version of firmware which the third party hardware should be executing. The two firmware version indicators are compared and if they differ, an upgrade to the existing firmware is required. The system then retrieves the upgrade firmware from a remote location. The upgrade firmware is then stored in the third party hardware.

Abstract: The present invention provides different scheduling criteria depending on overall system performance in an effort to maintain fairness among mobile terminals and sustain a required QoS level. The invention is particularly effective for multi-carrier systems, wherein scheduling must also take into consideration the carrier used to transmit the scheduled data. In one embodiment, the present invention determines the spread of throughput rates for all mobile terminals being served by a given base station and bases the scheduling criteria thereon. Preferably, a standard deviation calculation is used to measure the throughput spread. The standard deviation of throughput associated with a collective group of mobile terminals is indicative of the differences between the lowest and highest throughputs with respect to the average throughput for the collective group of mobile terminals.

Abstract: In a method and apparatus for measuring and controlling signal gain of a backward Raman amplifier having multiple pump lasers as used in optical communications networks, Raman pump power levels required to provide a uniform gain across a range of wavelengths in an optical fiber are determined by a combination of theoretical calculations and empirical measurement. A system of non-linear differential equations is solved for various pump powers and used to build a look-up table relating desired average Raman gain to the relative pump powers required to provide a uniform gain across a range of wavelengths. The linear relationship between Raman pump power and average Raman gain is determined by measuring data signal power levels at specific Raman pump powers. A desired average Raman gain is first applied to the linear relationship to determine total power required, and then applied to the look-up table to determine the required relative pump powers.

Abstract: multiple sub-streams are aharmonicaly interleaved into a high speed data signal by interleaving successive blocks of data from each sub-stream into the high-speed data signal using a predetermined interleaving pattern that is different for two consecutive sequences of N (an integer >2) blocks of data within the high-speed data signal. The resulting irregular distribution of bits of each sub-stream within the high speed data signal reduces the probability that error bursts due to low frequency noise will be localized in one or more of the recovered sub-stream extracted from the high speed data signal. This improved distribution of bit errors across the sub-streams reduces bit error rates in the most highly errored sub-streams, and thereby enables an increase in signal reach.

Abstract: Voice messages are downloaded from a voice messaging server to a handheld computing device where the voice messages may be reviewed and acted upon. The voice messages may first be converted from the file format native to the voice messaging server into a compressed data format. The result of the compression, a message file, may include a compressed audio portion and an information portion, which includes details associated with the message such as calling line ID and time of day. In one scheme, the compression is performed at the voice messaging server and the message files are downloaded to the handheld over a wireless connection. In another scheme, compression may be performed at a desktop PC which has downloaded voice messages from the voice messaging server. A connection between the handheld and the desktop PC allows a transfer of the message files to the handheld computing device. Once the message files are stored on the handheld computing device, a voice message interface application executed by the handheld computing device allows text details associated with the voice message to be displayed. The audio portion of the message files may be reviewed using audio playback capabilities that are standard on many handheld computing devices.

Abstract: A collaboration services suite is adapted to support a plurality of integrated telecommunications services accessed by geographically dispersed team members using a virtual team environment (VTE) client that generates a graphical user interface (GUI) for each of the respective team members. Communications sessions are automatically set up by the collaboration services suite in response to request messages generated by the VTE client when a team member initiates a communications session request using the GUI. Team members require no knowledge of another team member's communications device address in order to initiate a communications session. The collaboration services suite includes a VTE server that communicates with the VTE clients, a presence engine that collects and maintains a status of communications devices specified in a current profile of the team member; and, a call server for handling setup and control of a voice component of each communications session completed.
