RESTON, Va.--(BUSINESS WIRE)--Concurrent with the announcement by the GSMA of nationwide joyn Rich Communications Services in Spain, Ascom Network Testing, the leader in mobile network testing, optimization and benchmarking, today announced that a mobile operator in Spain will be using its TEMS Monitor Master mobile application performance monitoring solution to efficiently deploy and assure service quality for joyn RCS services.RCS-e is a standard being driven by the GSMA that will enable consumers to have IM, live video sharing and file transfer across any device, on any network, with anyone in their mobile address book. To retain and attract subscribers, carriers will increasingly offer these premium, assured RCS-e services as an alternative to over-the-top (OTT) services.With GSMA’s announcement of joyn service availability, Spain becomes the first country in the world to offer a fully interoperable rich communications solution, supported by Spain’s three largest mobile operators: Movistar (Telefonica), Orange and Vodafone. The new joyn services enable customers to chat and enrich messaging or voice calls by exchanging images or video simultaneously during calls, in a private and secure manner, with any member of their contact list that has joyn, regardless of the user’s network or mobile device. Additional services such as voice over IP (VoIP) or IP-video calls will be introduced in the near future. These services may be used on both the operators’ mobile networks and on Wi-Fi networks.Ascom
