The GSM Association (GSMA) and China Mobile completed multi-vendor trials of interoperable "Image Share" services.
This service, which allows mobile customers to share images with the person they are talking to on a phone call, was tested using mobile applications and devices provided by Nokia, Ericsson, Siemens, Motorola, Samsung and Comneon on an Internet Protocol (IP) multimedia subsystem (IMS) provided by Nokia Siemens Networks in China Mobile’s laboratories in Beijing.
The ability to send images across Global System for Mobile Communications (GSM) networks was also verified using interworking capabilities provided by Aicent.
The GSMA said it envisages that Image Share services, together with voice and video streaming, will form an important part of the multimedia communication experience enjoyed by both consumers and business users.
There is a demand to be able to share images while engaged in an ongoing communication, whether it is people discussing pictures from a party or other social event, or an estate agent sending pictures of a house during a conversation with a prospective buyer.
The GSMA, drawing on input from operators and vendors, developed guidelines for the Image Share service.
These guidelines are based on Internet Engineering Task Force (IETF)-developed protocols such as Message Session Relay Protocol (MSRP), Real-Time Transport Protocol (RTP), Session Initiation Protocol (SIP) and, in particular, file transfer for SIP, as well as 3rd Generation Partnership Project (3GPP) specifications for IMS and combinational services.
These protocols and systems enable near real-time communication over wireless and wireline IP networks and are also the basis for ongoing work on other services such as instant messaging in the Open Mobile Alliance standards body, said the GSMA.

"Although these tests were the first of their kind, they showed that the world's leading vendors have taken significant steps towards interoperability," said Alex Sinclair, chief technology officer of the GSMA. "Interoperability across networks and across devices is the key to the success of any new person-to-person service and these tests bode well for the development of an exciting range of IMS-enabled communications services."
