As Long Term Evolution (LTE) networks are getting rolled out, both service providers and users are expecting significant benefit from considerably faster data rates, reduced latency, enhanced spectral efficiency and a simpler IP-based network architecture — which collectively facilitates the delivery of new broadband services.

To handle exponential growth in data traffic from growing number of bandwidth-intensive applications and data-intensive devices, IP Multimedia Subsystem (IMS) has been selected as the technology to provide full convergence at all operational layers across fixed/wireless operations and to maximize network utilization.

DIAMETER is the signaling protocol for this all-IP based IP Multimedia Subsystem (IMS) in the 3G network and Evolved Packet Core (EPC) networks for 4G LTE. Today DIAMETER has been standardized as the protocol for policy management, charging, subscription and mobility management in next generation networks.

teleSys' offerings for LTE / IMS signaling networks allows Network Equipment Providers, System Integrators and Service Providers a wide range of solution options to meet signaling-based service requirements.

teleSys' Intelligent Diameter Controller for LTE/IMS networks:

teleSys' Intelligent Diameter Controller (iDC) offers efficient control of upsurging DIAMETER signaling traffic to telecom operators.

It is a state-of-the-art signaling transfer solution for DIAMETER signaling with intelligent routing, address translation and security while resolving scalability, interoperability and high-availability challenges efficiently. It plays a key role in managing DIAMETER signaling for Authentication, Authorization, Charging, Mobility Management and QoS control.

Built on teleSys' carrier-proven High Available and Scalable framework, iDC platform has been already deployed and can be offered for several solution needs including:

  • Centralized Routing in CORE network
  • Policy Routing as Diameter Routing Agent(DRA)
  • Edge Routing in compliance with Diameter Edge Agent(DEA)
  • LTE Roaming
  • Load Balancer for Diameter signaling to Applications
  • Diameter Signaling Mediation
  • Service mediation with legacy network elements(SS7, RADIUS, LDAP etc.)

teleSys' DIAMETER Stack for LTE/IMS networks:

teleSys DIAMETER stack offers a highly customizable and flexible signaling protocol solution with an easy-to-integrate programming interface for 3G/4G applications and network elements to meet increasing demands for capacity and throughput performance.

Applications and Network elements which can utilize teleSys DIAMETER stack includes:

  • AAA Server
  • Policy Controllers (PCRF)
  • Diameter Routing & Edge Agent (DRA/DEA)
  • Diameter Load Balancer
  • Home Subscriber Server (HSS)
  • Application Server (AS)
  • Femto Gateway
  • Online/Offline Charging System (OCS/OFCS)
  • Mobility Management Entity (MME)
  • Subscription Locator Function (SLF)
  • Call Session Control Function (CSCF)
  • Service Delivery Platform (SDP)
  • Serving Gateway(SGW)
  • Packet Data Network(PDN) Gateway(PGW)

teleSys DIAMETER protocol stack is offered in both C and Java programming language to fulfill different categories of application needs, and distributed in either source code or binary licensing model.
