Embodiment Construction

[0039] The main features of the invention will be briefly described with reference to Figure 3, which schematically illustrates a multimedia communication session between two mobile terminals A and B. A session is performed according to a specific multimedia traffic originating from either of the two terminals, including voice and other data as described above. As in the sessions illustrated in Figures 1 and 2, terminals A and B are radio-accessed to their respective access networks via appropriate radio connections, as schematically illustrated by blocks 100A and 100B respectively. For each radio access, the different media of the multimedia session can be multiplexed onto a separate common radio channel (e.g. onto different time slots in the channel if TDMA (Time Division Multiple Access) techniques are used), or alternatively Different media are transmitted on separate radio channels, depending on the configuration of the terminal.

Abstract

A method and arrangement for controlling a multimedia communication session between a first terminal and a second terminal, the session being divided into a circuit-switched part and a packet-switched part. A notification on an event occurring in one of said circuit-switched and packet-switched parts is received in a common session server. The session server then reports to the other part of the communication session about said event, such that said other part can be controlled in response to said event.

Description

technical field [0001] The present invention generally relates to a method and apparatus for handling a multimedia communication session divided into a circuit-switched part and a packet-switched part. In particular, the invention aims to provide control of sessions between terminals involving both circuit-switched voice and packet-switched data such as video, images, text and the like. Background technique [0002] Fixed and mobile communication terminals have hitherto been mainly used to make voice calls. Standard and well-working communication technologies and protocols have been utilized to carry voice between fixed and / or mobile terminals using circuit-switched communication channels. In particular, radio-based circuit-switched channels for mobile terminals have been designed and optimized to provide acceptable quality and reliability for voice calls while requiring minimal bandwidth in order to increase network capacity. [0003] Many new telephony services are devel...
