Real-Time Monetization & Flexible Convergent Charging Engine.ระบบสร้างรายได้แบบเรียลไทม์ และ Charging Engine ที่ยืดหยุ่น

Most MVNOs start with either prepaid or postpaid and retrofit the other later — resulting in two separate billing stacks, two databases, and perpetual reconciliation headaches. Cipher Telecom's OCS eliminates this from day one.

Prepaid and postpaid accounts share a single unified database cluster. A subscriber can transition between payment models, activate a hybrid plan (postpaid core with prepaid add-on top-ups), or belong to a family-share bucket — all managed in one place, charged in real time, and reported consistently.

What this means in practice

• One customer record — no cross-system sync jobs or nightly batch reconciliation.
• Shared family buckets work naturally across mixed prepaid/postpaid members.
• Roaming costs are rated in real time against the subscriber's active plan, regardless of payment model.
• Revenue assurance: every event is authorized before delivery — no post-hoc debt write-off for prepaid.

The OCS communicates directly with the data plane using standard Diameter interfaces, implementing the full session charging loop in real time — no batch mediation, no off-path authorization proxy.

Data charging alone is not enough. Voice calls — both mobile-originated and mobile-terminated — must also be authorized and billed in real time, or the MVNO risks credit leakage on every prepaid voice session.

Cipher Telecom's OCS implements CAMEL Application Part (CAP) logic over the SS7 / SIGTRAN signaling path. When a subscriber dials, the host MNO's switch triggers a CAP interaction with our OCS before completing the call. The OCS checks the subscriber's voice balance, reserves the appropriate credit, and issues a proceed instruction — including the maximum call duration. If the credit drops below the per-minute rate during the call, the OCS sends a mid-call re-authorization and, if required, a disconnect instruction.

CAMEL capabilities

• Pre-call balance verification before call completion — zero credit overrun.
• Mid-call re-authorization with configurable reserve thresholds.
• Announcement injection via external announcement nodes (e.g. "Low balance — 2 minutes remaining").
• Intelligent call routing — redirect based on balance state, time of day, or plan type.
• International roaming voice charging via CAMEL Phase 3 / Phase 4.

The biggest competitive advantage for an MVNO is promotional agility — launching targeted offers faster than the incumbent MNO. Cipher Telecom's OCS is built around that use case.

Product managers configure rate plans, promo bundles, shared family quotas and application-specific top-ups directly from the OCS control plane. No engineering ticket. No vendor professional-services engagement. No deployment window. A campaign can be live in under an hour.
