Carrier IOT (Interoperability Test)
The Carrier Interoperability Test (IOT) allows equipment suppliers to put mobile terminals into a network. Suppliers cannot sell mobile terminals unless the terminals pass the test specified by the carrier. In Japan, carriers usually define the carrier IOT for manufacturers, whereas overseas carriers use conformance tests developed by third parties (e.g., PTCRB and GCF) as the carrier IOT.

Test environment
Tests are done by changing the test environment as follows:
Mobile terminal protocol conformance tester (BS simulator) → Test laboratory → Real network (Field test)

Carrier IOT – Test flow
- Test plan
- Examines details of the latest test specifications.
- Identifies the differences from former test specifications.
- Verifies the test method.
- Verifies the test items.
- Develops the questionnaire for the carrier.
- Develops the questionnaire for the manufacturer.
- Test –
Implementation
/Execution - Executes the test.
- Pass/Fail - Determination
- Q&A/Negotiation with carrier
- Defect report
- Evaluation
/Report - Prepares the documents to be submitted.
- Develops the formal documents to be submitted to the carrier.
