    • The invention relates to a digital data transmission system with a non-transparent circuit-switched data connection (V.110) between a transmitting (A) and a receiving party (B), whose nominal data transmission rate may vary during a call. The data connection uses a sliding-window data flow control protocol involving transmission of data frames in a preset order, checking the order of received data frames based on this order information, acknowledgement of properly received data frames and retransmission of incorrect or missing data frames. The transmissing party (A) may temporarily group the data frames, whereby the resulting "wrong" order of frames inside the group or between groups may cause unnecessary retransmissions. In the invention this is eliminated so that the receiving party (B), upon detection of a missing data frame, delays the transmission of a retransmission request for a period of time that will ensure that the missing frame has not been sent later.
    • 本发明涉及一种数字数据传输系统,其在发射(A)和接收方(B)之间具有不透明的电路交换数据连接(V.110),其标称数据传输速率在呼叫期间可能变化。 数据连接使用涉及以预定顺序传输数据帧的滑动窗口数据流控制协议,根据该订单信息检查接收到的数据帧的顺序,确认正确接收到的数据帧以及重发错误或丢失的数据帧。 传送方(A)可以临时对数据帧进行分组,从而导致组内或组之间的结果“错误”的帧顺序可能导致不必要的重传。 在本发明中,这被消除,使得接收方(B)在检测到丢失的数据帧之后延迟重传请求的传输一段时间,以确保丢失的帧尚未被发送。

    • The invention relates to a digital telecommunications system, and particularly a method for non-transparent data tranmission. There is a non-transparent data connection (V.110+L2R/RLP) between a transmitting party (A) and a receiving party (B), on which channel coding is employed. The transmission buffer buffers the data frames to be transmitted and stores the transmitted data frames until it receives an acknowledgement of successful reception. In accordance with the invention, this is avoided by monitoring the quality of the non-transparent connection, and if the quality of the connection drops to a specific threshold value, by changing the channel coding scheme of the connection for a more efficient one. Simultaneously, however, more channel capacity is allocated for the connection in according with the chosen channel coding scheme so that the original nominal user data rate can be maintained unchanged or nearly unchanged.
    • 本发明涉及一种数字电信系统,特别是一种用于不透明数据传输的方法。 在采用信道编码的发送方(A)和接收方(B)之间存在不透明的数据连接(V.110 + L2R / RLP)。 发送缓冲器缓冲要发送的数据帧,并存储所发送的数据帧,直到其接收到成功接收的确认。 根据本发明,通过监视不透明连接的质量,并且如果连接的质量下降到特定阈值,则通过改变连接的信道编码方案以获得更高效的连接来避免这种情况。 然而,同时,根据所选择的信道编码方案,为连接分配更多的信道容量,使得原始标称用户数据速率可以保持不变或几乎不变。

    • In a communications system, the subscriber data in a home network (HLR) of a subscriber (UE) is provided with a subscriber ciphering profile which indicates whether an unciphered call, session or data packet is to be rejected, accepted or handled in some other manner. A serving network (MSC/VLR, SGSN,UTRAN) checks the subscriber ciphering profile in one or more of the following cases: 1) for each setup of an unciphered call or connection, 2) for each unciphered packet switched data transmission session, or 3) for each packet data transmission originating from subscriber equipment, and rejects or accepts the unciphered call, connection, session, or data packet, respectively, according to the subscriber ciphering profile. As a result, unciphered calls, sessions, or packet data transmissions will be reliably rejected if the network operator or the user sets the subscriber ciphering profile accordingly.

    • A digital mobile communication system has a high-speed non-transparent data connection between a transmitting and a receiving party (MS, TAF). For the data connection, parallel subchannels (ch1-chn), corresponding in number to the nominal data transfer rate, have been allocated on the radio interface. A radio link protocol (RLP) is responsible for transmitting data over the radio interface, and for acknowledging correct data frames and for retransmitting defective data frames. A transmission buffer (63) buffers the data frames to be transmitted and stores the data frames transmitted until it receives an acknowledgement of successful reception. In order to reduce interference and power consumption, user data is transmitted by using as many of the allocated subchannels as required by the actual user data rate at any one time. On the other allocated subchannels, transmission is interrupted or discontinuous transmission is activated.
    • 数字移动通信系统在发送和接收方(MS,TAF)之间具有高速非透明数据连接。 对于数据连接,在无线电接口上分配了与标称数据传输速率相对应的并行子信道(ch1-chn)。 无线电链路协议(RLP)负责通过无线电接口发送数据,并且用于确认正确的数据帧和重发缺陷数据帧。 发送缓冲器(63)缓冲要发送的数据帧,并存储发送的数据帧,直到它接收到成功接收的确认。 为了减少干扰和功耗,用户数据在任何一个时间通过使用实际用户数据速率所要求的尽可能多的分配子信道来发送。 在其他分配的子信道上,传输中断或不连续传输被激活。
