摘要:
A Method for controlling an establishment or a modification of a connection according to a packet based transmission scheme in a communication network (100) comprising a plurality of nodes (102-112) is proposed. The connection (113) to be established or modified comprises or utilizes one or more entities potentially causing a transmission delay for a transmission over the connection. An indicator indicating an expected accumulated delay for the connection (124) is sent between nodes controlling the connection and one of the nodes controlling the connection checks the indicator when it performs a decision on the packetisation time to be applied for the connection.

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.

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.

The invention is related to a method for transmitting data in a telecommunications network and a device, e.g. a network node, utilizing that method, where said data transfer requires the application of algorithms for coding and/or decoding (“codec”) on said data, where at least one of said network nodes provides a list (25) of available codecs and transmits it to a further network node, where said further network node chooses from the received list (25) and from a corresponding set of codecs available to the further network node a combination of codecs to be used when transferring said data, and where the received list (25) not only comprises direct codecs (28) but transcoding codecs (29), i.e. codecs requiring transcoding, as well.

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.
