GSMA SIP Trials led by TeliaSonera proved Video Share interoperability

(3GSM World Congress, Barcelona) TeliaSonera has led the GSM Association’s SIP Trial work with the participation of other key players in the industry. Continuing trials are paving the way for advanced SIP/IMS services to function smoothly across networks, terminals, platforms and national boundaries right from launch. Video Share is the latest example of services where interoperability has been demonstrated.


Video share service enables the participant in a voice call to send live video of what they are looking at to the other participant. Video share is expected to become a very popular service used to exchange everything from live holiday greetings to other footage of free-time activities and also more business-oriented uses, for example sending video of an item for sale.

The GSMA’s programme of interoperability trials was established to ensure that end users will be able to enjoy easy-to-access and easy-to-use next generation multimedia services, with a fully reliable service experience.

The tests make use of a technology called IP Multimedia Subsystems (IMS), to allow users to share video streams across the fixed and mobile networks in a fast and efficient way. IMS, which uses the Session Initiation Protocol (SIP) to initiate and manage connections, is a network architecture that many operators plan to use to deliver new services such as instant messaging, push-to-talk, videotelephony and multiplayer games to mobile users.

Demos at 3GSM World Congress
Video share service interoperability will be demonstrated by the GSMA at the 3GSM World Congress.
