Embodiment Construction

[0040] In the following description, for purposes of explanation and not limitation, specific details are set forth (eg, particular software, techniques, etc.) in order to provide a thorough understanding of the invention. However, those skilled in the art will recognize that the present invention may be practiced in other embodiments that do not depart from these specific details. In other instances, detailed descriptions of well-known methods, devices, and circuits are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0041] figure 1 is a block diagram scheme illustrating an interworking network and nodes according to the present invention, and Figure 8 is an example of a network 50 supporting SIP. Figure 8 Schematically illustrates how IMS fits into a mobile network architecture in the case of a 3GPP PS access network. The Call / Session Control Function (CSCF) operates as a SIP proxy with the IMS. The 3GPP architecture def...

Abstract

The present invention relates to a node and a method for transmitting initiation information related to a SIP-proxy server between an IMS-client stored in a user equipment (UE) and a Gateway GPRS Support Node (GGSN) via a Access Network (AN) and a Tunnelling Termination Gateway (TTG) node in IP core network. The present invention offers smooth transfer between different protocols and Interworking between different networks.

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...
