Abstract
An apparatus, method, system and computer program product is configured for optimizing usage of bandwidth extension. Codecs to be used in a communication connection between communication network nodes are negotiated. The negotiating includes indicating a capability of a communication network node to expand bandwidth by indicating support of the communication network node for a wideband codec towards another communication network node; and indicating a lack of codec transparency for the wideband codec at the communication network node.

1-27. (canceled)
An apparatus, comprising:
- a codec negotiation means configured to negotiate codecs to be used in a communication connection between communication network nodes, and to indicate, in negotiation, a capability of a communication network node to expand bandwidth by indicating support of the communication network node for a wideband codec towards another communication network node, and indicating a lacking of codec transparency for the wideband codec at the communication network node.
An apparatus, comprising:
- detection means configured to detect via an interface connection a capability of a terminal to expand bandwidth.
A mobile services switching center server system, comprising:
- an apparatus having a codec negotiation means configured to negotiate codecs to be used in a communication connection between communication network nodes, and to indicate, in negotiation, a capability of a communication network node to expand bandwidth by indicating support of the communication network node for a wideband codec towards another communication network node, and indicating a lacking of codec transparency for the wideband codec at the communication network node.
A communication node system, comprising:
- a first apparatus having a codec negotiation means configured to negotiate codecs to be used in a communication connection between communication network nodes, and to indicate, in negotiation, a capability of a communication network node to expand bandwidth by indicating support of the communication network node for a wideband codec towards another communication network node, and indicating a lacking of codec transparency for the wideband codec at the communication network node, said codec negotiation means further configured to indicate the capability of the communication network node to provide narrowband-wideband transcoding by at a same time including the wideband codec in a category of indirect codecs and including a narrowband codec in a category of direct codecs in a codec negotiation list for use in a communication node codec negotiation;
- and
- a second apparatus having a detection means configured to detect via an interface connection a capability of a terminal to expand bandwidth, a further codec negotiation means configured to negotiate codecs to be used in the communication connection between the communication network nodes, and a bandwidth expansion capability activation means configured to activate a bandwidth expansion capability.
