Abstract: The invention relates to a technique of operating a call control node controlling at least one section of a call path. The call path includes between two opposite edge nodes a multi-section harmonization path along which codec selection is to be harmonized. A method embodiment of the technique, wherein the call control node is a transfer node in the harmonization path between the edge nodes, comprises the steps of determining if the call control node is a transfer node of the harmonization path; determining if a codec used for the at least one section controlled by the call control node fulfils a predefined harmonization criterion; and providing, in case the used codec does not fulfill the harmonization criterion, a harmonization trigger indication to at least one of the edge nodes of the harmonization path for initiating harmonization.

Abstract: 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 neighbouring 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 neighbouring ring nodes based on the added indication.

Abstract: 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.

Abstract: A system and method are described for controlling the setup of a connection in a communication network that includes a set of nodes, such as Mobile Switching Centers (MSCs) and Media Gateways (MGWs). In one example, a speech connection is established between MGWs subject to the control of the MSCs, which can selectively activate or deactivate codecs along the connection. The codecs are selected from a list of supported codecs, each potentially affecting connection quality by differing amounts. A Total Accumulated Impairment (TAI) element is forwarded between the MSCs and step by step updated by these MSCs that includes individual partially accumulated impairment values corresponding to each of the supported codec candidates. Each individual indicator value provides information representative of the expected accumulated impairment along a candidate connection path leading up to, and including, the corresponding codec. By providing information pertaining to the expected accumulated impairment along each candidate connection path, the MSCs can determine an optimum sequence of codecs so as to minimize the overall connection impairment.

Abstract: The invention relates to the setting up of a connection between an originating terminal and a terminating terminal. Both terminals may connect via the same access network. The access network accesses a core network through an access gateway. The access gateway transmits and/or receives connection set-up signalling transmitted along a signalling path through at least the core network. Using an information element in the connection set-up signalling, information on media plane access needs of nodes in the signalling path is collected and provided for determining whether a local shortcut of a media path can be established in the access network.
