摘要： Perceived interactivity in user communications is achieved by reducing a perceived delay switching the active transmitter in the communication without having to reduce actual transmission and setup delays associated with a communication exchange. A sound signal is identified in the user communication. The sound signal is analyzed to identify or estimate a sound signal segment. The sound signal segment is preferably (though not necessarily) located at the beginning or the end of the sound signal. The sound signal segment may be selected directly from the sound signal itself, from a modified version of the sound signal, or from a signal associated with the sound signal. A determination is made that a length or duration of the sound signal segment should be or can be modified. One or more modifications for the sound signal segment are determined and are provided to one or more processing units to perform the modification(s).

摘要： In packet communications that employ header compression/decompression, the computational complexity of checksum generation can be reduced by re-using static checksum information associated with header bits that do not change from header to header. The static checksum information can be used together with information about header bits that do change from header to header, in order to generate a desired checksum. The checksum can then be used to verify a reconstructed header produced from a compressed header by a header decompressor.

摘要： Header compression repair techniques are accomplished, in various aspects, modes, embodiments, and implementations, by a remote terminal (40), by a header decompressor (46) for use at a remote terminal (40), and by methods of operating the remote terminal and/or decompressor, and (optionally) in some aspects, modes, embodiments, and implementations by taking into consideration aspects of structure and operation of a header compressor (25) as well. The remote unit (40) comprises a transceiver (42) or the like which receives, over a link (36) such as an air interface (38), packets including packets having headers which have been compressed and packets which are potentially out-of-order. The header decompressor (46), upon detection of non-receipt of packets anticipated in a flow (34) of packets over the link, stores, with respect to each non-receipt, a snapshot of header decompression context information existing at the non-receipt. Then, when the header decompressor detects header decompression failure for a subsequently received packet, the header decompressor determines (e.g., by executing a repair process) whether header decompression of the subsequently received packet can be achieved using one of plural stored snapshots.

摘要： A system, method, and apparatus for increasing the efficiency of the compression of a communication protocol for use over bandwidth limited communication links. One aspect of the present invention uses the knowledge of the structure and content of communication protocols to form a static dictionary or static binary code tree. As a result, the compression efficiency can be greatly increased. Another aspect of the present invention provides a combined static and dynamic dictionary or binary code tree to perform communication protocol compression. In one aspect of the invention, the static binary code tree or static dictionary is constructed by studying flows of data protocols in the conditions of their intended usage.

摘要： A telecommunications network has first and second entities (201 and 202) which communicate by sending a packet (22) having a compressed header (24′). A header compression key (23) is associated with (e.g., included in) the packet. The header compression key has a first field (23A) which, in a first mode of the invention, is utilized exclusively for distinguishing between different flows of compressed packets (CIDs). In a second mode of the invention, the first field (23A) of the header compression key can be utilized either for distinguishing between the different flows of compressed packets or for distinguishing between different header compression identifiers. Whether the first field of the header compression key is employed exclusively for distinguishing between different flows of compressed packets (the first mode) or can also be employed for distinguishing between different header compression identifiers (second mode) depends on a value in a second field (23B) of the header compression key. In the second mode, a first subset of values for the first field of the header compression key is employed to distinguish between different header compression identifiers, while a second subset of values for the first field is employed to distinguish between the different flows of compressed packets.

摘要： Techniques are provided for efficiently compressing and reconstructing the time stamp value of a real time communications packet whose time stamp value does not fall within a normally expected sequence of time stamp values. A first part of the time stamp value is selected by the header compressor and transmitted. A second part of the time stamp value is estimated by the header decompressor based on elapsed time between receipt of consecutive packets. The header decompressor combines the second part with the first part received from the header compressor to produce a reconstructed time stamp value.
