摘要： A power-supply expansion system includes a primary power-supply unit for providing a main power supply, a secondary power-supply unit for providing an auxiliary power supply, a power unit having a first and a second input terminal and an output terminal, and a control unit connected to the primary and the secondary power-supply unit. The control unit, based on a load value of the primary power-supply unit, selectively performs a power-supply expansion process for the secondary power-supply unit to feed the auxiliary power supply to the second input terminal. In the power-supply expansion process, the first input terminal receives the main power supply and the second input terminal receives the auxiliary power supply, and the power unit integrates the main and the auxiliary power supply into an output power supply, which is output via the output terminal. A power-supply expansion method applicable to the power-supply expansion system is also disclosed.

摘要： A method that allows for rapid inter base station handoffs in IP based wireless networks is disclosed. More specifically a technique to address the problem of accurate location management during rapid handoff across multiple base stations is described in this invention disclosure. The idea proposed uses a combination of Timestamp and Sequence number along with a message exchange protocol over the network to maintain the registration with only a single base station at any point of time.

摘要： In wireless networks where the goal is to support a large number of VOIP based cellular calls, large overhead headers in RTP voice packets are not acceptable. In wireless networks where multiple base stations are deployed, handsets may handoff from one base station to the other while in a voice call creating a large overhead. This disclosure describes an efficient way to extend a header compression algorithm and lower the overhead when the handset is in a voice call and hands off from one base station to another.

摘要： An extension to a heterogeneous MAC protocol that makes provisions for multi-frequency system architecture is described. A new frame structure for a multi-frequency xMAX system is introduced. Multi-frequency xMAX system is an extension of a single-channel xMAX system, where the available bandwidth is split into multiple channels to provide additional capacity and range. The new frame structure is followed by all channels and is designed to fulfill the requirements of multiple frequency operation. The new frame structure incorporates features that allow the handset to leverage the advantages of multiple frequency channels, especially in the event of interference. Also, a new mechanism to reduce the power consumption in the handset is discussed that significantly reduces the number of unnecessary receive operations at the handset.

摘要： This disclosure describes a dynamic pattern elimination compression method to eliminate redundant patterns, the content of which is not known a priori, by identifying the candidate dynamic patterns and marking them, then checking to see if there are any duplicate occurrences within the entire message by searching for markers, if a marker is found, checking to see if the pattern occurred before, if not, assigning a unique variable to the pattern, if so replacing the pattern with the variable that was assigned for this pattern, and if a pattern is found only once, removing the variable assigned to it.
