    • 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.
    • 为了快速建立呼叫,终端A向终端B发送由终端A支持的最高H.223多路复用器级别的填充序列和至少一个专有序列。 专有序列表示支持快速呼叫设置,并包含终端A支持的视频和音频编解码器。终端A监视由终端B发送的填充和专有序列。如果终端A从终端B接收专有序列,则终端A发送H .245 NonStandard请求消息,其中包含发送给终端B的专有序列中的信息,终端A支持的视频和/或音频功能,以及终端A使用的多路复用表的条目。终端A监测来自终端B的NonStandard请求消息 ,其中包含终端B的视频和音频功能以及多路复用表项。终端A和B已准备好在每个接收到来自另一终端的确认的终端上进行通信。

    • 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.
    • 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新发送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时段期间重传,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缓冲以进行重传以减少移动终端内的处理开销。

    • The present invention proposes a method, in a UE in wireless communication network, for communication, wherein the UE is configured one Pcell and at least one Scell, wherein a first Scell in the at least one Scell is in the state of configured but out-of-UL-synchronization, wherein the method comprises: performing no DL channel measurement. UE can trigger random access procedure according to the received MAC CE signaling, or it is mandatory that PDCCH order signaling has to be sent before MAC CE signaling, or MAC CE signaling is sent before PDCCH order signaling and the first Scell is set as de-active state in MAC CE signaling, UE changes into the state of configured and UL synchronization according to the detected PDCCH order signaling for the first Scell.
