Tekelec Cites Tier One Selection for Diameter Signaling supporting VoLTE

Tekelec has been selected by a Tier One mobile operator in the U.S. to expand its new Diameter network. The service provider will implement two new Tekelec Diameter Signaling Router (DSR) systems, in addition to the one announced in June 2011. The name of the customer was not disclosed.


The Tekelec Diameter Signaling Router (DSR) centralizes subscriber routing data and dynamically maps identification information, such as an MSISDN or IMSI, with the correct IMS Home Subscriber Server (HSS). Tekelec said its approach gives the service provider flexibility to move subscribers between databases and update databases when a new IMS HSS is added to the network, supporting future Voice over LTE (VoLTE) deployment.
