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 initiated secondary PDN connection procedure .
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 PDN connectivity
- IP CAN Session establishment for secondary PDN
This test case is executed as per 3GPP TS 23.401
