摘要： For quick call setup, terminal A sends to terminal B stuffing sequences for the highest H.223 multiplexer level supported by terminal A and at least one proprietary sequence. The proprietary sequence indicates support for quick call setup and contains video and audio codecs supported by terminal A. Terminal A monitors for stuffing and proprietary sequences sent by terminal B. If terminal A receives a proprietary sequence from terminal B, then terminal A sends an H.245 NonStandard request message containing the information in the proprietary sequence sent to terminal B, video and/or audio capabilities supported by terminal A, and entries for a multiplex table used by terminal A. Terminal A monitors for a NonStandard request message from terminal B, which contains video and audio capabilities and multiplex table entries for terminal B. Terminals A and B are ready to communicate upon each terminal receiving an acknowledgment from the other terminal.

摘要： This disclosure is directed to techniques for video call setup in a mobile video telephony network. In general, the call setup techniques reduce call setup delays by preemptively retransmitting NSRP packets before expiration of the timeout period ordinarily required for receipt of an NSRP ACK packet from the remote terminal. The retransmitted NSRP packets may be retransmitted during idle periods in which the modem layer in the sending mobile terminal has received no other data for transmission of the remote mobile terminal, thereby taking advantage of idle bandwidth. Multiplex data received by the modem can be locally buffered at the modem layer for retransmission. In this manner, retransmission does not require regeneration of the original call setup messages nor multiplexing. Instead, the previously generated and multiplexed data is buffered at the modem layer for retransmission to reduce processing overhead within the mobile terminal.
摘要翻译：本公开涉及用于移动视频电话网络中的视频呼叫建立的技术。通常，呼叫建立技术通过在从远程终端接收NSRP ACK分组通常需要的超时时间到期之前抢先重传NSRP分组来减少呼叫建立延迟。重传的NSRP分组可以在发送移动终端中的调制解调器层没有接收到用于远程移动终端的传输的其他数据的空闲周期期间重传，从而利用空闲带宽。调制解调器接收的多路复用数据可以在调制解调器层进行本地缓冲以进行重传。以这种方式，重传不需要再生原始呼叫建立消息或多路复用。相反，先前生成和复用的数据在调制解调器层被缓冲以进行重传以减少移动终端内的处理开销。

摘要： An improved method and system for determining round-trip time (RTT) during a radio link protocol (RLP) wireless communication link. The RTT estimate is negotiated by both sides of the RLP communication link without the need for the 3-way handshake generally required for RLP synchronization. The method includes techniques used by both sides of the RLP communication link to dynamically update and refine their initial, negotiated RTT estimates.

摘要： Techniques for avoiding data loss and reducing registration overhead in a wireless packet data communication system are disclosed. In one embodiment, a mobile station adds each connection to a connection list following registration with the PCF. The mobile station need not reregister a connection included in the connection list when it again enters the PCF's coverage area. In another embodiment, a PDSN maintains a connection table, with one or more connections for each mobile station. The PDSN transmits data to the mobile station along one of the connections. In yet another embodiment, a PDSN transmits on an active connection, if one exists. In yet another embodiment, connections in a connection list or connection table are removed when a corresponding inactivity timer expires. Various other embodiments are also presented. Benefits include allowing mobile stations to travel between PCFs without re-registering, which reduces registration overhead and increases system capacity, and avoidance of data loss from network initiated data directed to a mobile station, resulting in timely delivery of the data and reduction of system resources allocated to retransmission of data.

摘要： This disclosure describes audio decoding techniques for decoding audio information that needs to be properly clocked. In accordance with this disclosure, the number of audio samples in decoded audio output can be adjusted to compensate for an estimated error the in decoder clock. That is to say, rather than adjust the decoder clock to synchronize the decoder clock to the encoder clock, this disclosure proposes adding or removing audio samples from the decoded audio output in order to ensure that the decoded audio output is properly timed. In this way, the techniques of this disclosure can eliminate the need for an adjustable or controllable clock at the decoding device, which can save cost and/or allow legacy devices that do not include an adjustable or controllable clock to decode and output audio information that needs to be properly clocked.

摘要： A method and apparatus for conserving home agent resources in mobile Internet Protocol (IP) deployment is disclosed. In a wireless communication system supporting mobile IP, a release candidate set is generated and updated during operation of the network. When an inactivity timer associated with a mobile node satisfies a condition, the mobile node is listed in the release candidate set. Successful communication with the mobile node results in removal from the release candidate set. The release candidate set is accessed when a home agent desires to reclaim resources on an overload condition.

摘要： A method and apparatus for conserving home agent resources in mobile Internet Protocol (IP) deployment is disclosed. In a wireless communication system supporting mobile IP, a registration request message is sent by a mobile node to a home agent. The registration request includes a care-of address. A home address is provided for the mobile node and is associated with the care-of address. The home agent provides an inactivity timer for the mobile node to monitor the communication activity of the mobile node. In addition, the home agent monitors a condition of a resource. When the condition satisfies an overload condition, the home agent starts a reclaiming resources process that utilizes the inactivity timer for the mobile node.
