IPLOOK and SigScale Partner to Deliver Low-Cost, Standards-Based Mobile Network Solution for Emerging Operators
IPLOOK Technologies Co., Ltd (“IPLOOK”), a global provider of 3G/4G/5G converged mobile core network solutions for Operators, MVNOs, WISPs, and Enterprises, has announced a strategic partnership with SigScale Global Inc (“SigScale”), an open-source software company specializing in OSS/BSS solutions for Communications Service Providers (CSPs). Together, they are launching a cost-efficient, end-to-end mobile network solution built entirely on 3GPP and TM Forum standards—ideal for new and emerging operators.
Validated Interoperability: IPLOOK EPC + SigScale OCS
The joint solution integrates:
- IPLOOK’s 4G infrastructure: including eNodeB and the Evolved Packet Core (EPC)
- SigScale’s Online Charging System (OCS): a real-time, TM Forum-compliant charging platform
Recently, the two companies successfully completed interoperability testing between IPLOOK’s EPC and SigScale’s OCS, confirming seamless integration and standards compliance.
Solution Highlights
IPLOOK EPC offers:
- Fully integrated, scalable 4G core with smooth upgrade path to 5GC
- Open support for all major eNodeB vendors
- Multi-charging mode support (RADIUS, OCS, CG)
- Standardized 3GPP interfaces for roaming with MNOs
SigScale OCS provides:
- Real-time prepaid charging for voice, data, and SMS
- TM Forum-standard APIs (e.g., Open Digital Architecture compliant)
- Highly scalable, fault-tolerant microservices architecture built in Erlang
Together, the solution delivers a complete, interoperable, and affordable stack—reducing total cost of ownership (TCO) while accelerating time-to-revenue for new operators in emerging markets.
“We are delighted to collaborate with IPLOOK and eager to help operators advance market opportunities with this powerful joint solution,” said Vance Shipley, CEO at SigScale. “SigScale OCS complements IPLOOK EPC with a business support layer that enables immediate commercialization of the network.”
