MetroPCS Communications has chosen Tekelec to provide SIGTRAN, SIP and Diameter session management as well as Number Portability and Performance Management solutions. 
Tekelec said its Diameter Signaling Router (DSR) creates a Diameter signaling core that relieves LTE and IMS endpoints of routing, traffic management and load balancing tasks and provides a single interconnect point to other networks. In addition, MetroPCS will use Tekelec’s performance management solution to gain visibility into network services and subscriber usage. MetroPCS will use the solution to monitor Quality of Service (QoS) for subscribers, as well as Service Level Agreements (SLAs). The solution provides key performance indicators (KPIs) in both pre-built and customer-defined reports, giving MetroPCS the flexibility to examine traffic, troubleshoot issues and analyze subscriber activity — the foundation for measuring the quality of experience.
