This test case is used for validating the components of an EPC or an eNB for a valid attach procedure.
In this test case, ABot can simulate the eNB and UE and any other node of the 4G EPC like MME, SGW, PDN-GW, HSS and PCRF. The eNB and UE sends an Initial Attach request message with a valid IMSI value. The eNB and UE receives an Attach Accept message, in an ideal case. Now, UE triggered detach procedure with detach type normal detach.
The procedures completed in this test case are –
- Diameter Capabilities Exchange
- Initial UE Message
- Authentication Information Retrieval
- Authentication procedure(AKA)
- Tunnel Management
- IP CAN Session
- UE Initiated Detach
- IP CAN Session deletion.
This test case is executed as per 3GPP TS 23.401
