Core Interworking Gateway

About Core Interworking Gateway

Core Interworking Gateway (CIG) provides a seamless pathway to resell your mobile services.

It enables you to onboard wholesale partners simply, securely, and rapidly, so you can expand your wholesale business by accelerating partner time-to-market. It does so by providing you with a single central integration point to connect wholesale partner systems such as OCSs and PCRFs to your network

CIG excels at integrating wholesale partner systems with your mobile network to propel your success:

  • Operator-focused: CIG is the only solution on the market that specifically caters for the MNO’s interests when integrating with wholesale partners. It especially addresses the security issues and integration complexities that complicate projects.
  • Seamless Integrations: CIG enables seamless integration with any standards-based third-party charging systems, expanding your potential market and making your wholesale offering more competitive.
  • Shorter ROI: CIG lowers onboarding costs for each wholesale partner, shortening your ROI and payback period. This enables onboarding of even marginally profitable partners, helping you scale your wholesale services effectively.
  • Accelerated Deployments: CIG enables much quicker deployment of services for wholesale partners, which dramatically quickens their time to market and reduces costs.

  • Built-In Diameter Routing Agent (DRA): Routes Diameter traffic to the required endpoints, saving the cost of a separate Diameter routing solution.

Why CIG?


In today's digital world, more and more wholesale partners like MVNOs, MVNEs, and resellers are emerging. This is great news because they bring wholesale revenue to mobile operators and added value to customers.

Supporting wholesale partners requires an interworking solution. This solution enables them to use their own Online Charging Systems and Policy and Charging Rules Functions to control and charge their customers for your mobile services.

CIG is a robust interworking solution that is key to enabling wholesale partners to operate seamlessly on your network. It is a crucial enabler for a successful wholesale product offering, helping you monetise your network while managing risks and reducing costs:

  • Grow Revenue: Generate revenue through a wholesale business solution:
  • New Customers: Grow your customer base through wholesale partnerships to gain access to new customers.
  • Excess Network Capacity: Maximise the utilisation of your current network capacity and achieve revenue growth without adding additional network costs.
  • Niche Markets: Expand into niche markets by engaging partners with existing customer bases.
  • Manage Risks: Address deployment time and security concerns when connecting wholesale partners:
  • Quick and Simple Integrations: Easy activation and deactivation of partners reduces the risk of new MVNO or reseller failures by lowering onboarding costs.
  • Single Point of Control: CIG provides you with one core point for third party integration, configuration, reporting, monitoring, and troubleshooting.
  • Core Network Topology Hiding: CIG’s architecture hides the mobile operator’s core network topology from the outside world.
  • Offline Partner Charging: When a partner’s OCS goes offline, a partner can request temporary Charging Bypass activation, allowing customers to use MNO services within set credit limits.
  • Reduce Costs: Reduce your costs by streamlining integration efforts and making more effective use of network resources:
  • Easier Support: A centralised control point reduces support workload by streamlining setup, leading to fewer and easier issues.
