    摘要： The present disclosure discloses a state transition method and apparatus based on ROHC, and a computer storage medium. The method comprises: when it is determined that a state machine of a compressor is in an Initialization and Refresh (IR) state, transiting a state of the state machine of the compressor from the IR state to a First Order (FO) state when it is learned that a decompressor corresponding to the compressor can only successfully parse a static field of a service stream packet header; and transiting a state of the state machine of the compressor from the IR state to a Second Order (SO) state when it is learned that the decompressor corresponding to the compressor can successfully parse the static field and a dynamic field of the service stream packet header; when it is determined that the state machine of the compressor is in the FO state, transiting a state of the state machine of the compressor from the FO state to the SO state when it is learned that the decompressor corresponding to the compressor can successfully parse the dynamic field of the service stream packet header; and when it is determined that the state machine of the compressor is in the SO state, transiting a state of the state machine of the compressor from the SO state to the FO state when it is learned that the decompressor corresponding to the compressor fails to parse the dynamic field of the service stream packet header within a preset time threshold.

    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 provides for the sharing of context information between a compressor (214,245,415) and decompressor (225,235,435) at each communication entity (210,230,410,430) in a communication system. As a result, context information will be shared for each channel pair. In another aspect of the present invention, multiple communication sessions between communication entities (210,230,410,430) may share the same context information for the compression and decompression of communication messages.

    摘要： In various embodiments, a system comprising a network interface, a processor, and a non-transient memory medium operatively coupled to the processor is disclosed. The memory medium is configured to store a plurality of instructions configured to program the processor to receive a digital bit stream, transform the digital bit stream to an encoded digital bit stream. The encoded digital bit stream comprises at least one of a gateway channel, a composite channel, or a data channel, and any combination thereof, and provides the encoded digital bit stream to the network interface for transmission. A non-transitory computer-readable memory medium and a computer-implemented method also are disclosed.

    摘要： The invention provides a method to divide a sequence of symbols being encoded as variable lengths prefix-free code-words in a compressed image file into sub-sequences which can be decoded without referring to any other sub-sequence. Hence, it is possible to divide the original data into several sub-sequences which can be decoded in parallel and assembled to form the fully decoded sequence at the end. In particular, the invention relates to a way to determine a synchronization state in a sub-sequence allowing correct decoding of the remainder or the sub-sequence.
