Description

technical field

[0001] The present invention relates to interworking WLANs, and more particularly to methods and nodes for communicating initiation information. Background technique

[0002] IP Multimedia (IPMM) is an example of a service that provides a dynamic combination of voice, video, messaging, data, etc. within the same session. By increasing the number of possible combinations of media and basic applications, the number of services offered to end users will increase and the human-to-human communication experience will be enriched. This will lead to new generation of personalized and rich multimedia communication services, such as peer-to-peer multimedia communication, IPTV and so on. These services may be based on the IP Multimedia Subsystem (IMS) architecture, which is a technology defined by the Third Generation Partnership Project (3GPP) to provide IP multimedia services over mobile communication networks (3GPP TS 22.228, TS 23.228, TS24.229, TS 29.228, TS 29.2...
