摘要： The invention proposes to introduce a method for a Radio Access Network for providing “Local Switching” between call legs of a call. Within said method the Radio Access Network receives a call identifier for a leg of a call from a Core Network to be handled by the Radio Access Network. The Radio Access Network stores said received call identifier, compares said received call identifier with stored call identifiers for call legs of calls via said Radio Access Network. If said received call identifier matches a stored call identifier the Radio Access Networks establish local switching of call legs identified by the matching call identifier. In an alternative embodiment, the invention proposes to introduce a method for a Core Network for providing local switching for call legs of a call. Within said method the Core Network receives or generates a call identifier for a leg of a call. The Core Network stores said received call identifier and identifies a respective Radio Access Network for said leg of said call. Thereafter, the Core Network compares said call received identifier with stored call identifiers for call legs of calls via said identified Radio Access Network. If said received call identifier matches a stored call identifier enforce local switching of call legs identified by the matching call identifier. The invention furthermore provides for respective Nodes of the respective Networks employing the invention.

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.

摘要： 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.

摘要： 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.

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： A method of modifying a call setup message for a call from a first terminal to a second terminal, the call setup message being sent from the first terminal to a network node via an intermediate node which handles at least some signaling or traffic associated with the call, wherein the network node is responsible for negotiating call setup requirements for the call to the second terminal, the method comprising the steps of: intercepting the call setup message at the intermediate node; identifying one or more preferences or capabilities associated with the intermediate node which may impact the way in which the intermediate node can handle signaling or traffic associated with the call; modifying the call setup message based on information relating to said preferences or capabilities; and sending the modified call setup message to the network node, in order that the node can effect said negotiations based on the modified message.
