context: a MODIFY PDP CONTEXT ACCEPT message to ensure the context has been set up. Expected sequence Specific message contents Step 2: TI flag (octet 1, Bit 8) in TI IE is set to â0â and value of TIO (octet 1, Bits 765) is set in range 0-6. Step 3: TI flag in TI IE is set to â1â and value of TIO is the same as in Step 2. Step 5: The Linked TI information element in ACTIVATE SECONDARY PDP CONTEXT REQUEST message specifies the TI for the PDP context already activated. The SS can derive PDP address for the secondary PDP context from the Linked TI, TI flag in TI IE is set to â0â and value of TIO is the same as in Step 2 and 3 NSAPI IE value is different from NSAPI value in Step 2 Step 6 and 8: TI flag in TI IE is set to â1â and value of TIO is the same as in Step 5. Step 9: TI flag in TI IE is set to â0â and value of TIO is the same as in Step 5. 11.1.4.1.1.5 Test requirements To pass the test the UE shall: - when the SS responds to Secondary PDP context activation request initiated by the UE,
description: The Test Interface (TI) is a specific interface used in testing scenarios within the 3GPP specification, particularly for Quality of Service (QoS) and PDP context management. It involves the exchange of messages with specific flags and values to ensure proper setup and activation of contexts.
explanation: Given the context from 3GPP TS 34.123, section 11.1.4.1.1, TI is clearly described as an interface element (IE) involved in the modification and activation of PDP contexts, with specific flags and values being set to facilitate testing and ensure QoS. This indicates that TI plays a role in communication between network components, fitting the definition of an Interface.
