26.4.1 Introduction
The text in this subclause is intended to develop a standardized way of creating lower layer failures whilst testing the performance of Layer 3 signalling. There are two groups of lower layer failures: 1) Detected by analysis of reception at Layer 1 (3GPP TS 05.08, 3GPP TS 04.08 / 3GPP TS 44.018), 2) Data link layer fa...

26.4.2 Layer 1 reception failures
The absence of reception of correct frames on the SACCH until the S counter reaches value 0 will be interpreted as a Layer 1 failure.
683b5b8a98f7b1390ddd5516ea9247a2
51.010-1
26.4.3 Data link layer failures
Many kinds of error cases can be caused in Layer 2. For example too many "T200 - time-out/retrying" - pairs. NOTE 1: All types of data link failures are indicated similarly to the RR layer (Release Indication). NOTE 2: All types of L1 failures are indicated similarly to each layer (Abort Indication, Error Indication).

26.4.4 Lower layer failures, used for the tests in clause 25
For L3 testing different lower layer failures are performed: 1) T100 time-out in Layer 1. 2) Too many T200 time-outs consecutively in Layer 2.

26.5 Handling of unknown, unforeseen, and erroneous protocol data, and of parallel transactions
683b5b8a98f7b1390ddd5516ea9247a2
51.010-1
26.5.1 Handling of unknown, unforeseen, and erroneous protocol data, and of parallel transactions / unknown protocol discriminator
An MS ignores messages with unknown protocol discriminator. This allows for the introduction of new messages which will be ignored by MS of earlier phases.

51.010-1
26.5.1.1 Conformance requirements
If the mobile station receives a standard L3 message with a protocol discriminator different from those specified in table 9.2/3GPP TS 04.07, the mobile station shall ignore the message. References 3GPP TS 04.07, subclause 11.2.1.

26.5.5.2.2.2 Test purpose
To verify that an MS having been paged and having an RR connection established ignores an MM message with syntactically incorrect IE except for the fact that it sends an MM STATUS message with reject cause #96. This is tested in the special case of an IDENTITY REQUEST message in which the (mandatory) identity type IE s...

26.5.5.2.3 Non-semantical mandatory IE errors / MM / comprehension required
The "comprehension required" mechanism allows for the introduction of essential new information elements into messages, such that a message is ignored and a report is sent if the new information element is not understood.
