    摘要： A power control system in a TDMA radio communication system has traffic channels which are associated with a set of speech/channel encoding modes. Each mode has a different mix of speech encoder bit rate and data protection bit rate but the same total available gross bit rate. The transmitter includes a power control unit that replaces a mode allocated to a channel by another mode having either a higher or a lower data protection bit rate and either a lower or a higher speech encoder bit rate if the sound to be encoded requires either a lower or a higher speech encoding bit rate. The power control unit also controls a power adjustment unit that either reduces or increases the output power of the transmitter to a lower or a higher level such that an estimated decoded speech quality measure at the receiver is substantially constant.

    摘要： Low rate data signals, such as standard TTY signals and standard DTMF signals, can be effectively analyzed and encoded by speech encoders employed in conventional digital cellular system. This is accomplished by providing a low rate data encoder in the transmission path of the low rate data signal, just prior to the speech encoder used by the digital cellular system. In so doing, the standard, low rate data signal is transformed (i.e., modified) by the low rate data encoder into a signal that is more compatible with the speech encoder. Similarly, a low rate data decoder is provided at the receiving end of the transmission path to decode the modified, low rate data signal.

    摘要： In a radio communication system in a mobile to mobile call with one good (AMR102) and bad (AMR515) radio link, the good radio (AMR102) link is forced by the poor (AMR515) link to use a more robust AMR coded mode (AMR515) and thereby using excessive power (232). A capacity loss in such system is avoided by adjusting the power level (212) for the connection with the good link (AMR102).

    摘要： Techniques for discontinuous transmission (DTX) and fast in-band signaling of configuration changes and protocol messages in speech communications systems provide cost efficiency in terms of radio transmission capacity, in terms of fixed line transmission, and in terms of implementation effort. An exemplary method for performing discontinuous transmission (DTX) in a communications system in which source data is interleaved for transmission from a first component in the system to a second component in the system includes the steps of detecting periods of source data inactivity, and transmitting silence descriptor (SID) frames from the first to the second component during the periods of source data inactivity, certain of the transmitted SID frames being interleaved using a different interleaving algorithm as compared to that used for source data. For example, the source data can be block diagonally interleaved, and certain of the SID frames can be block interleaved. An exemplary method for effecting configuration changes in a communications system includes the step of transmitting an escape frame in place of a speech data frame, the escape frame including a gross bit pattern to distinguish the escape frame from speech data frames and conveying a configuration change indication. The escape frame can further include a data field to indicate a particular configuration change to be made. For example, where the communications system is an AMR system, an escape frame can be used to change an active codec mode set. Alternatively, an escape frame can be used to change a phase of codec information.

    摘要： The invention relates to a method and a device for avoiding interruptions in voice transmission in a cellular communication system. Voice data are thereby divided into segments, and the segments are associated with transmission quanta, so-called bursts. A number of segments is coded in a first transmission mode and is made available for transmission. Said first transmission mode is, for instance, for a transmission at full rate. Additional segments, which follow, are subsequently coded in a second transmission mode and are made available for transmission. The second transmission mode is, for instance, for transmission at half rate. Through the change from a first transmission mode to a second transmission mode, parts of the associated transmission quanta remain unused by applying the so-called interleaving. Said unused transmission quanta are used for performing additional functions, such as initiating a hand-over or FACCH signaling.

    摘要： The invention relates to a method for setting up a connection between an originating mobile entity and a terminating mobile entity connecting to the same radio access network of a mobile communications network, the radio access network accessing a core network through a serving access gateway serving one of the two mobile entities the method performed by the serving access gateway comprising the steps of receiving a connection setup message for establishing the connection between the originating and the terminating mobile entity, wherein the connection setup message transmitted along a signalling path in the core network comprises an information element storing media plane access needs of at least one network node in the signalling path of the core network, wherein the media plane access needs indicate the needs of a network node in the signal path of the core network to access a media plane of the connection to be set up. Additionally it is checked whether any of the network nodes in the signalling path of the core network needs access to the media plane of said connection to be set up, wherein, if none of the network nodes needs access to the media plane and if the serving access gateway needs access to the media plane at least the following steps are carried out: a media gateway that is handling a media stream of the serving access gateway is instructed to provide an uplink endpoint for the connection to the originating mobile entity and an uplink endpoint for the connection to the terminating mobile entity for the connection to be set up, and the radio access network is informed to transmit the media stream of the originating and the terminating mobile entity to the media gateway of the serving access gateway needing access to the media plane.

    摘要： The Invention proposes a method for a Control Node (MSC) of a Core Network (CN) for late activation of a User Plane between a Radio Station (eNodeB, NodeB, BTS) and a control node (RNC, BSC) of a Radio Access Network (eUTRAN, UTRAN, URAN, GERAN, GRAN, RAN) of a call to be set-up. Furthermore, a method for a control node of a Radio Access Network for late activation of a User Plane between a Radio Station and a control node of a Radio Access of a call to be set-up is proposed MSC receives an indication that a call involving said MSC and a BSC of a RAN shall be set-up. MSC gains knowledge that said BSC is adapted for a late User Plane Activation. MSC instructs said BSC that the User Plane between the Radio Station and the BSC/RNC shall be reserved. Upon detecting that the User Plane of said call shall be through connected, MSC instructs the BSC to activate the reserved User Plane between Radio Station and BSC. In addition corresponding nodes are proposed.

    摘要： A network entity for a radio communication network includes a processing unit which causes a first resource and a second resource for a terrestrial interface of the radio network to be seized, where the first resource is distinct and different from the second resource. The entity includes a network interface through which a handover request or an assignment request message identifying the first and the second resource is sent. A network entity for a radio communication network includes a network interface which receives a handover request message or an assignment request message identifying a first resource and a second resource. The first resource is distinct and different from the second resource. The entity includes a processing unit that selects one of the first and second resources, allocates a radio channel associated with the handover or assignment, selects a bearer for a terrestrial interface and seizes resources for the interface.
