LTE to prompt telecoms to spend $282 mn on CSRC: Infonetics

LTE 4G network expansion will prompt telecom operators to spend a cumulative $282 million globally on centralized signaling and routing control (CSRC) equipment from 2014 to 2018, said Infonetics Research.

Vendors in CSRC, which help operators relieve congestion and simplify network management as they bridge legacy networks and next-generation IP, including Italtel, NetNumber, and Sonus will benefit from this Capex plan of telecoms.

CSRC platforms facilitate interworking between the two by enabling operators to manage both legacy and next-gen signaling protocols, including SIP, Diameter, SS7, and Radius.”

The report said CSRC platforms have primarily been adopted for IP interexchange with Session Initiation Protocol (SIP) redirect utilizing local policy.

A number of applications can be integrated in a CSRC platform to broaden capabilities, including ENUM / Domain Name System (DNS), breakout gateway control function (BGCF), home subscriber server (HSS), Diameter signaling control, IMS call session control function (CSCF), and policy and charging rules function (PCRF).
