WIPRO LIGHTWEIGHTLTE CORE & WIPRO LTE TEST COREReference Solutions for enabling rapid development ofnext generation LTE Evolved Packet Core (EPC)

INDUSTRY TRENDSThe wireless market today supports multiple standards such as 2G/3G, CDMA, WiMAX, WiFi and LTE. Due to data traf�c explosion in recent times, most Commu-nications Service Providers (CSPs) are enhancing their packet core for each of the access domains and incurring signi�cant OPEX/CAPEX costs which is not commensurate with the increase in their revenues. Since LTE supports multiple access convergence at the packet core level, CSPs can deploy a uni�ed LTE Converged Core which will help signi�cant reduction in CAPEX and OPEX. There is an increasing trend to deploy specialized LTE network for other vertical markets such as Defense, Public Safety and Private Enterprises which requires small footprint, ruggedized, converged system supporting multiple mobile broadband technologies for their communication needs. LTE Converged Packet Core Solution addresses both the CSP and vertical market requirements.

BUSINESS CHALLENGES

SOLUTION OVERVIEW

Capable of interfacing with multiple wireless access technologiesHelps them increase revenues by offering differentiated servicesProvide seamless migration to LTE and LTE-A technologies from existing 3G technologies Minimize their initial CAPEX and long term OPEX requirement

Communication service providers have realized the need to upgrade their packet core network to support LTE technology. The need of the hour is a LTE Packet core solution which meets the following characteristics:

Specialized software and hardware system offering enhanced security and custom features targeted towards their requirementsSmall form factor, low capacity system at reduced costSupport fast network roll out time with very low human intervention

Large enterprises in retail, utilities and energy segment,defense and public safety sector will be migrating towards LTE technologies to meet their next generation communication needs. They will be requiring specialized LTE Packet core solution meeting following characteristics:

• Wipro Lightweight LTE Evolved Packet Core (EPC) solution is a hardened reference implementation enabling rapid development of highly compact LTE Evolved Packet Core system for Public Safety, Defence, Large Enterprises and Rural Markets.• Wipro LTE Test Core is reference implementation that can be used by test equipment vendors to quickly build test equipment for LTE Evolved Packet Core• The highlights of the Wipro Lightweight LTE Evolved Packet Core solutions are:

The distributed architecture (Control plane/Applications and Bearer Plane) also enables building standalone products like MME, SGW and PGW for equipment vendors who have whitespace in their LTE Evolved Packet Core product portfolio
