摘要： A method for handling, by a ring node of a network having a ring topology, a data transfer of data packets through the network via which the data packets are transmitted to their destination node, wherein each ring node has two neighboring ring nodes. The method includes detecting data packets of an incoming data transfer received from a non ring node to be transmitted through the network to their destination node. Furthermore, a ring direction is added to the data packets of the incoming data transfer, the indication indicating in which direction the data packets of the incoming data transfer are passed through the network having the ring topology. The data packets of the incoming data transfer are forwarded to one of the two neighboring ring nodes based on the added indication.

摘要： A routing system transfers data packets of real time communication services of a call, and includes a converter receiving media gateway control protocol encoded first control data and processing the first control data to obtain second control data. The system, based on the first control data, allocates a first transport address for a first routing port for incoming data packets, and allocates a second transport address for a second routing port for outgoing data packets. A central control entity controls a central control entity controlled network of forwarding elements, and determines a static pathway through the network of forwarding elements based on the second control data. A first end of the static pathway corresponds to the first routing port and a second end corresponds to the second routing port. The central control entity controls a data plane flow of a stream of the data packets along the static pathway.

摘要： A method, a control node and a program unit for controlling the establishment or modification of a connection for a subscriber having a subscription in a communication network are disclosed. The connection is to be established or modified between nodes that are adapted to employ a coding scheme selected from a plurality of supported coding schemes potentially affecting connection quality. In accordance with the invention a subscribed quality level indicating a target quality level for the subscriber associated with the subscription is determined, and a node controlling the connection checks the subscribed quality level when it selects a coding scheme to be employed for the connection.

摘要： The invention relates to a technique for controlling establishment of a tandem free operation (TFO) for transfer of TFO frames including content frames between a first and a second transcoder unit without transcoding of the content frames. A method aspect of the technique comprises the steps of transmitting, in case a remotely used codec does not meet a codec compatibility condition, a first transparent mode message indicating to in-path equipment a transparent mode for subsequent transparent TFO negotiation, and transmitting, in the transparent mode, a TFO configuration frame indicating a local TFO codec list.

摘要： The invention proposes several methods for codec handling. In specific, methods involving providing a supported codec list of a Call Control Server are described. A node receives information, whether a terminal supports a wideband codec, wherein the information is received in call set up signaling from the terminal of the subscriber. Furthermore, configuration information is retrieved, whether a Radio Access Node supports the wideband codec. Additionally, information is retrieved, whether a media gateway supports the wideband codec, wherein the information is either provided by the operator or retrieved from the media gateway (MGW1, MGW2, MGWx). The information is analyzed and in response to the analysis a supported codec list is provided. Furthermore, alternative embodiments and devices adapted for the methods are disclosed.
