International Carrier Sales & Solutions (ICSS), the international wholesale arm of Deutsche Telekom (DT), has announced its new LTE Diameter Signaling service, which gives customers the ability to roam over 4G networks while travelling internationally. The service gives end users the ability to take advantage of 4G services, such as higher speeds, enhanced performance and expanded connectivity capabilities. The LTE Diameter Signaling service was made possible through the dedicated IP exchange (IPX) platform from ICSS; it solves the interoperability problems caused by the wide range of technologies and infrastructures and allows seamless roaming across differing mobile standards. Via its IPX network, ICSS can connect its LTE roaming customers with more than 800 mobile networks and over one million hotspots for global signaling roaming connectivity.
