摘要： The present invention relates to the technique of handover in mobile telephony. A new Transcoder and Rate Adaptation Unit (100 FIG. 3) is introduced which provides two uplink (230, 250 respectively, FIG. 3) and two downlink (240, 260 respectively, FIG. 3) channels. The use of these two channels (230, 250 respectively, FIG. 3) on the uplink during handover provides for the use of distributed handover on the uplink. The result minimizes the audible interruption during handover by minimizing the loss of Traffic Channel frames to what is possible within the GSM standard. Additionally, interruption of the speech or background noise during these lost frames is masked by an error concealment algorithm, since the Transcoder and Rate Adaptation Unit (100 FIG. 3) still has information from the Base Transceiver Station responsible for transmission before the handover.
摘要翻译：本发明涉及移动电话中的切换技术。引入了新的代码转换器和速率适配单元（100图3），其提供两个上行链路（分别为230,250，图3）和两个下行链路（分别为240,260，图3）信道。在切换期间在上行链路上使用这两个信道（分别为230,250，图3）提供了在上行链路上使用分布式切换。该结果通过最小化在GSM标准中可能的业务信道帧的损失来最小化切换期间的可听到的中断。另外，在这些丢帧中的语音或背景噪声的中断被错误隐藏算法掩蔽，因为代码转换器和速率适配单元（100图3）仍然具有来自负责在切换之前发送的基站收发信机的信息。

摘要： The invention concerns an arrangement for the supervision of a number of devices belonging to a group of devices in a telecommunication system, concerning seizure statistics, i.e. the ratio between the number of normal seizures and the total number of seizures, which devices, (relays, relay sets, registers etc) alternately are seized and released. Two counters are connected to each of the individual devices, a first counter for the registration of the total number of seizures of the device, and a second counter for the registration of the number of seizures of the device exceeding a certain minimum time. A first quotient between these numbers is periodically established for each individual device. A first adder adds the total number of seizures for each device belonging to the device group. A second adder adds the number of seizures exceeding a certain minimum time for each device in said the group. A second quotient is established between such two numbers concerning the whole device group. In a comparing circuit a comparison is made in turn between said first quotient for the individual devices and said second quotient. An alarm arrangement delivers alarm signals when the difference between these quotients exceeds a certain value.
