摘要： A transcoder which prevents tandem coding of speech in a mobile-to-mobile call within a mobile communication system uses a speech coding method for reducing transmission rate on the radio path. The transcoder includes a speech coder, which encodes the speech signal into speech parameters for transmission to a mobile station, and decodes the speech parameters received from the mobile station into a speech signal according to the speech coding method, as well as a PCM coder for transmitting an uplink speech signal to and for receiving a downlink speech signal from a PCM interface in the form of PCM speech samples. In addition to the normal operation, the transcoder transmits and receives speech parameters through a PCM interface in a subchannel formed by least significant bits of the PCM speech samples. Thus, it is possible to prevent tandem coding while maintaining the standard PCM interface, and the signaling and services associated thereto.

摘要： A speech signal is transmitted over a radio path by a mobile station, and is received in a first base station. The speech signal, encoded using encoding parameters, is forwarded in the information frames from the first base station to a remotely located speech decoder. Each of the information frames carries a synchronization word and a synchronization check bit recurring at predetermined intervals within the information frame. The information frames are received at the remote speech decoder. The remote speech decoder is synchronized with one of the received information frames using the synchronizing word. Speech encoding parameters are extracted from the received information frames, and the recurring synchronization check bit is monitored within the received information in order to detect an error in the recurring synchronization check bit in the received information frames.

摘要： A compression method and apparatus for a transmission link in a telecommunications network between switching centers each associated with a compression apparatus connected thereto by a number of PCM transmission channels for receiving a speech signal from each PCM transmission channel and transferring the speech signal via an interconnecting PCM link having a transmission capacity lower than the number of transmission channels received from the switching center to the other compression apparatus. The speech signal between the first switching center and the compression apparatus is either a pure PCM coded speech signal or a PCM coded speech signal in which one or more least significant bits of the PCM samples provide a sub-channel for lower-rate vocoded speech containing the same speech information as the PCM samples but in a vo-coded format. The interconnecting link has one or more PCM channels in each of which all bits of the PCM samples are utilized for providing two or more subchannels in each of which lower-rate vocoded speech or data can be transmitted. One compression apparatus is arranged, in response a PCM coded speech signal containing the subchannel, to multiplex the content of the subchannel into one of the subchannels in the interconnecting link, and, in response to a pure PCM coded speech signal, to encode the latter into a lower-rate vocoded speech signal and to multiplex the vocoded speech signal into one of the subchannels in the interconnecting link.

摘要： The invention concerns a method in a digital network system for controlling the transmission of terminal equipments. Terminal equipment includes a PTT (Push-to-Talk) function in order to at least activate the transmission to be carried out to the said network system, and wherein the terminal equipment for voice control of the said PTT function also includes a VOX (Voice Operated transmission) feature, which can be activated/passivated and which is implemented by a VRE (Voice Recognition Engine) function. In the method stops are performed—the VRE function is used to search for an established keyword from an audio signal,—the established keyword is recognised from the audio signal,—a turn to transmit is requested from the network system,—a turn to transmit is received from the network system,—the transmission is connected and the granted turn to transmit is indicated,—the transmission is carried out, and—the transmission is passivated. In the said VOX feature before the said VRE function the audio signal is monitored by a VAD. (Voice Activity Detection) function arranged in connection with terminal equipments, and whereby when activating the said VOX feature in the terminal equipment steps are performed before the said partial steps the terminal equipment's incoming audio signal is processed with the VAD function searching it for a signal form in accordance with an established criterion, and—when a signal form according to the established criterion is detected in the audio signal, the said VRE function is activated to search for an established keyword.

摘要： A telecommunication network and a routing method, wherein user data are routed via an access network (2) to a gateway device (5) of a core network (7) connected to the access network (2) via a first interface. The control of the gateway device (5) is performed by supplying a control information from the core network (7) to the gateway device (5) via a second interface, and the user data are routed directly between the access network (2) and the gateway device (5) via the first interface. Thus, the user data are routed directly from the access network (2) to the gateway (5), whereas the control can be performed via a dedicated and open control interface. Processing resources can be shared between several applications and trunking gains can be utilized. Furthermore, real-time transport capabilities can be provided by a simple method of connecting the Internet to the mobile network.

摘要： The present invention relates to a digital mobile communication system in which mobile stations (MS) and the fixed network comprise speech coders. The speech coders of the fixed network are located remote from the base stations (BTS) in transcoders (TRCU). In MMC calls, however, the transcoders are controlled to operate so that the frames received from a first base station (BTS) are forwarded with minor modifications through a pair of tandem connected transcoders to a second base station, without carrying out any speech encoding or decoding in the trancoders. Consequently, speech coding is only carried out in the mobile stations, and the speech parameters are simply passed through the mobile communication network, resulting in a significant improvement in the speech quality as compared with the conventional tandem coding.
