S1AP protocol on the S1-MME interface as specified in ETSI TS 136 413 [1] in compliance with the relevant

5.1.1 TP naming convention
TPs are numbered, starting at 01, within each group. Groups are organized according to the TSS.

ERR Unknown, Unforseen and Erroneous Protocol Data

= sequential number (01 to 99)

5.1.2 Test strategy
As the base specification in ETSI TS 136 413 [1] contains no explicit requirements for testing, the TPs were generated
as a result of an analysis of the base standard and the PICS specification ETSI TS 103 497-1 [2].
5.1.3 TP structure
Each TP has been written in a manner which is consistent with all other TPs. The intention of this is to make the TPs
more readable and checkable. A particular structure has been used which is illustrated in Table 2. Table 2 should be
read in conjunction with any TP, i.e. please use a TP as an example to facilitate the full comprehension of Table 2.

TP to the next.
NOTE 2: All messages are considered as "valid and compatible" unless otherwise specified in the test purpose.
This includes the presence of all mandatory IEs as specified in ETSI TS 136 413 [1].
NOTE 3: An IE can be embedded into another IE. This is expressed by indentations, e.g. if Message1 contains IE1
and IE2 where IE1 has IE3 embedded this will be expressed like this:
sends/receives Message 1
 containing IE1
  containing IE3
  indicating .
 containing IE2

NOTE 4: IE value fields used for e.g. identification or address should be equal in the scope of TP if not stated
otherwise.

5.2.1 PICS references
All PICS items referred to in this clause are as specified in ETSI TS 103 497-1 [2] unless indicated otherwise by
another numbered reference. PICS items are only meant for test selection, therefore only PICS items with status
optional or conditional are explicitly mentioned.
