iBasis, a KPN company, announced the launch of its LTE Signaling Exchange (LSX), which will allow MNOs to connect to hundreds of other operators through a single interconnect and assure LTE roaming interoperability across multiple vendors.

Demand for the LSX is a result of the disruptive nature of LTE and the evolution from traditional SS7 (MAP) signaling to IP-based Diameter signaling. The iBasis LSX runs on iBasis’ IPX network, a multiservice, global IP network that delivers high quality voice and data services for mobile operators.

A number of mobile network operators, including UNE, a leading telco based in Colombia, and Dutch operator KPN have agreed to connect to iBasis’ LSX Sandbox, which provides a comprehensive trial environment in preparation for launching commercial LTE roaming services.

The LSX Sandbox enables testing of a full range of technical operations, including basic roaming, policy control and charging, Diameter interoperability, signaling accounting and MAP-Diameter interworking.

The iBasis LSX reduces complexity and cost while ensuring high quality of service for roaming customers. The LSX allows MNOs to connect to hundreds of downstream operators through a single interconnect and normalizes messages to enable interoperability on behalf of each roaming partner. It also interworks with existing SS7 networks.
