Image Share
Image Share is a service for sharing images between users during a mobile phone call. It has been specified for use in a 3GPP-compliant cellular network by the GSM Association in the PRD IR.79 Image Share Interoperability Specification.[1] According to the specification, "The terminal interoperable Image Share service allows users to share Images between them over PS connection with ongoing CS call, thus enhancing and enriching end-users voice communication." An Image Share session begins by end-users setting up a normal circuit switched (CS) voice call.
