摘要： The soft state of a header compression scheme in a communication system carrying packet traffic including a real time communication signal can be updated during periods of communication signal inactivity, during which there is no need to transmit the communication signal. The header compression soft state can also be updated by stealing bits from the communication signal to carry the header update information. If the communication signal includes source encoded data, the header compression soft state can be updated selectively based on the bit rate of a codec that produced the source encoded data.

摘要： In packet communication paths that include header compression, header fields of packets to be communicated are altered. The alteration of the header fields does not disturb their functionality, and is transparent to the header compression scheme of the packet communication path. The altered header fields are provided for compression by the header compression scheme, resulting in improved performance of the header compression scheme. Performance improvements can also be achieved in packet communication paths that do not use header compression, by violating the integrity of header fields in packets to be transmitted over the packet communication path.

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.

摘要： Network devices, servers, and modules operating within MCA capable to selectively defer delivery of non-time sensitive content are provided. A network device (315) includes a communication interface (410) configured to enable communication with a client device (310), and to receive a request for a content delivery from the client device (310). The network device also includes a processing unit (420) configured to determine whether to defer the request depending on a network load at a time when the request has been received.
