摘要： PROBLEM TO BE SOLVED: To provide a system and method for synchronizing transmission of compressed headers in data packets between a transmitter and a receiver having a preferred wireless application which is an improvement of RFC2508. SOLUTION: In a system having a transmitter transmitting a plurality of packets each containing a header to a receiver, a method with which synchronization of the transmission of the compressed headers between the transmitter and the receiver is established includes a step in which the transmitter transmits a current packet from the transmitter to the receiver containing information indicating that the transmitter is prepared to send subsequently transmitted packets having the headers to be compressed in comparison with the header contained in the current packet and a step in which the receiver transmits an acknowledgement packet indicating that the receiver has received the current packet from the receiver to the transmitter.

摘要： Methods and apparatuses are provided for facilitating gesture recognition. A method may include constructing a matrix based at least in part on an input gesture and a template gesture. The method may further include determining whether a relationship determined based at least in part on the constructed matrix satisfies a predefined threshold. In an instance in which the relationship does not satisfy the predefined threshold, the method may also include eliminating the template gesture from further consideration for recognition of the input gesture. In an instance in which the relationship satisfies the predefined threshold, the method may further include determining a rotation matrix based at least in part on the constructed matrix. Corresponding apparatuses are also provided.

摘要： A system and method for transmitting content such as electronic mail from a sending electronic device to a recipient electronic device. When content is to be sent, it is first determined whether the sending electronic device possesses a reference content item that has redundancy with the current content item. If so, it is determined whether the recipient electronic device includes a copy of the reference content item. If the recipient electronic device possesses a copy of the reference content item, a compression algorithm is used to compress the current content item, with the compression being based upon the reference content item existing in both the sending electronic device and the recipient electronic device. The compressed current content item is then transmitted to the recipient device, where it is decompressed and made available.

摘要： A method and device for multiplexing a stream of packets containing uncompressed and compressed packets. In a compressed packet, an identification bit pattern is inserted between the compressed payload data and the transport header so that a decompressor can determine whether the packet is compressed based on the presence of the identification bit pattern. Because the compressed packet carries the original transport header of a packet with minor modification, an intermediate node on the path of packet can see information in the transport header. In contrast, the transport header in an IPComp packet is part of IP payload and thus compressed.
摘要翻译：一种用于复用包含未压缩和压缩分组的分组流的方法和装置。在压缩分组中，在压缩的有效载荷数据和传输报头之间插入识别位模式，使得解压缩器可以基于识别位模式的存在来确定分组是否被压缩。由于压缩包携带少量修改的分组的原始传输报头，所以分组路径上的中间节点可以看到传输报头中的信息。相比之下，IPComp包中的传输报头是IP有效载荷的一部分，因此被压缩。

摘要： The present invention concerns methods for efficiently supporting Voice over Internet Protocol (VoIP) on the Forward Packet Data Channel (F PDCH) in CDMA 2000 1xEV-DV systems. Active speech in VoIP is encoded using, for example enhanced variable rate codec (EVRC), which produces 171, 80 and 16 bits per 20 ms of speech for Rate 1, Rate %2 and Rate 1/8, respectively. However, about 60% of the time a user is inactive during a speech session, so an inordinate amount of system bandwidth is comprised of rate 1/8 VoIP packets. In one embodiment of the present invention the apparatus of the present invention identifies the Rate 1/8 voice frame packets and discards them. In another embodiment of the present invention, the apparatus of the present invention identifies the Rate 1/8 voice frame packets and selects some of them for further transmission. In both embodiments the efficiency of channel utilization is increased since the amount of channel band width used to communicate relatively little information, e.g., gaps of silence, is decreased.
摘要翻译：本发明涉及在CDMA 2000 1xEV-DV系统中有效支持前向分组数据信道（F PDCH）上的因特网协议语音（VoIP）的方法。 VoIP中的活动语音使用例如增强型可变速率编解码器（EVRC）进行编码，其分别为速率1，速率％2和速率1/8的每20毫秒的语音产生171,80和16位。然而，在用户在语音会话期间不活动的时间的大约60％，因此系统带宽的过多是由速率1/8的VoIP分组组成的。在本发明的一个实施例中，本发明的装置识别速率1/8语音帧分组并丢弃它们。在本发明的另一个实施例中，本发明的装置识别速率1/8的语音帧分组，并选择其中一些用于进一步传输。在两个实施例中，信道利用的效率增加，因为用于传达相对较少的信息的信道带宽的量，例如，沉默的间隙被减少。

摘要： A method and device for compressing a text string into a compressed string, taking into account case sensitivity of the text string. Compression can be performed in lossy mode or lossless mode. In lossy mode, the text string is parsed to determine its case sensitivity so that a search for finding a match for the text string in a reference source is based on the case sensitivity. Alternatively, the case configuration of the characters in the text string is transformed into a target case, and a case-sensitive search is performed to find a match for the case-transformed text string. In lossless mode, a case-insensitive search is performed for finding a match for the text string regardless of its case sensitivity, and a case-info-element is attached to the compressed string so that the compressed string can be reconstructed based on the case-info-element.

摘要： A method and system for in-band signaling between network nodes that uses a state announcement mechanism or a header field in a message to signal one of a plurality of possible events. A first network node containing a decompressor defects an event and assigns the detected event a state. The first network node assigns the state an identifier and transmits the identifier in-band to a second network node containing a compressor. The second network node processes the identifier to obtain the event. The first network node receives and de-compresses messages compressed and sent by the second network node. The in-band transmission uses a state announcement mechanism or a header field in a message between the second network node and the first network node to signal events.
