Groups are organized according to the TSS. Additional references are added to i
27、dentiSl the actual test suite and whether it applies to the network or the user (see table 1). Table 1: TP identifier naming convention scheme Identifier: css-ciutcgroup-cnnn = supplementary service: e.g. “CUG“ = type of IUT: U User N Network = group = seauential number (001-999) 2 digit field repre
28、senting group reference according to TSS 5.1.2 Source of TP definition The TPs are based on EN 300 138-1 i. ETSI 9 TP part Header Stimulus Reaction Message structure ETSI EN 300 138-5 V3.1 .I (2002-04) Text tab CR Ensure that the IUT in the see below for message structure or if the action is sending
29、 see below for message structure , etc. and enters andlorand remains in the same state(s) or and enters state with CR message containing a a) information element with b) a encoded as or including 5.1.3 TP structure Each TP has been written in a manner which is consistent with all other TPs. The inte
30、ntion of this is to make the TPs more readable and checkable. A particular structure has been used and this is illustrated in table 2. This table should be read in conjunction with any TP, i.e. use a TP as an example to fully understand the table. Table 2: Structure of a single TP Example see table
31、1 slause X.X.X VOO, N10, etc. Veceiving a XXXX message :o request a. sends, saves, does, etc. using en bloc sending, . SETUP, FACILITY, CONNECT, . Bearer capability, Facility, . I and back to a orb, 5.1.4 Test strategy As the base standard EN 300 138-1 i contains no explicit requirements for testing
32、, the TPs were generated as a result of an analysis of the base standard and the PICS specification EN 300 138-2 2. The criteria applied include the following: - - only the requirements from the point of view of the T or coincident S and T reference point are considered; whether or not a test case c
33、an be built from the TP is not considered. 5.1.5 Test of call states Many TPs include a reference to the IUTs final call state after the realization of the TP. In these cases the TP includes the requirement to ensure that the IUT has entered this particular final call state. Ensuring that the IUT is
34、 in a particular call state shall be realized by following the procedures described in clause 5.8.10 of EN 300 403-1 7. According to these procedures, the IUT on receipt of a STATUS ENQUIRY message, shall respond with a STATUS message indicating, in the third octet of the Call state information elem
35、ent, the current call state of the IUT. This exchange of messages is not mentioned explicitly in each TP but is considered to be implicit in the reference to the final call state. This way of phrasing the TPs has been used to avoid over-complicating the text and structure of the TPs and to improve t
36、he readability. ETSI 10 ETSI EN 300 138-5 V3.1 .I (2002-04) 5.2 Network TPs for CUG All PICS items referred to in this clause are as specified in EN 300 138-2 2 unless indicated otherwise by another numbered reference. 5.2.1 Calling user interface 5.2.1 .I Explicit request 5.2.1.1.1 CUG call success

This combinatio
38、n is only tested in this clause as the “normal call“ output is the subject of the TPs in clause 5.2.1.2 (Default request).
