b63685a584764961b7ae3e51726522bc
104 081
8.1.1 Introduction of 'root scope'
To simplify scoping rules for predefined functions (see clauses C.1 to C.6 in ETSI ES 201 873-1 (V4.17.1) [i.1]) and Useful TTCN-3 types (see clause E.2 in ETSI ES 201 873-1 (V4.17.1) [i.1]) a 'root' scope will be introduced. In the hierarchy of scope units 'root' scope will be above the 'module definitions part' scope...

104 081
8.1.2 Module parameters
All parameterization (see clause 5.4 in ETSI ES 201 873-1 (V4.17.1) [i.1]) in TTCN-3 takes effect dynamically at runtime, except for the module parameters that are supplied by the test environment at the beginning of the execution, and then they do not change their values during test execution. Because of this differen...

8.1.3 Bitstrings, Hexstrings and Octetstrings
Values of types bitstring, hexstring and octetstring (see clause 6.1.1 in ETSI ES 201 873-1 (V4.17.1) [i.1]) will not only be denoted by the uppercase 'B, 'H, 'O characters, but their lowercase equivalents 'b, 'h, 'o will also be enabled, like: '0101'b, 'ABCD'h and 'ABCD'o.
b63685a584764961b7ae3e51726522bc
104 081
8.1.4 Character strings
The default string type will be the current universal charstring type. The new and shorter string will be introduced for it, but for backward compatibility reasons the universal charstring keyword will also be kept. The current charstring type will be defined as a subtype of the new string type. This will allow to simp...

104 081
8.1.6 Communication port types
Since procedure-based communication will be moved to ETSI ES 201 873-12 (V5.1.1), in the core language only the message-based port type (see clause 6.2.9 in ETSI ES 201 873-1 (V4.17.1) [i.1]) will remain. In message-based port type definitions the keyword message will be optional (it will be kept only for backward comp...

The proposed backward-compatible modifications related to templates (see clause 15 in ETSI ES 201 873-1 (V4.17.1) [i.1]) are the following: • Templates without a (possibly empty) parameter list are static templates. They will be evaluated only once, at the place of their declaration. NOTE 1: A static template retains t...

8.1.10 Number of elements of lists (sizeof predefined function)
The functionality of the sizeof predefined function (see clause C.2.2 in ETSI ES 201 873-1 (V4.17.1) [i.1]) will be extended. It will be applicable not only for record or set type values and templates, but also for string and record of or set of values or templates. If it is applied for values and templates of: • recor...
b63685a584764961b7ae3e51726522bc
104 081
8.1.11 Conversion functions
Because the universal charstring becomes the 'default' string type, all the to/from character string conversion functions (see clause C.1 in ETSI ES 201 873-1 (V4.17.1) [i.1]) will have to/from universal string equivalents. Currently the following conversion functions of this kind are missing: int2unistr, bit2unistr, h...

8.2.6 Range-based loops
The specification of the range-based loops (see clause 19.4.2 in ETSI ES 201 873-1 (V4.17.1) [i.1]) will be clarified. In order to be able to iterate over partially initialized range expressions, and to keep the existing functionalities of the assignments (see clause 19.1 in ETSI ES 201 873-1 (V4.17.1) [i.1]), the spec...

5.1.3 Relationship
Given that an armed DP was encountered, the gsmSSF provides an information flow via a relationship. A relationship between the gsmSSF and the gsmSCF for the purpose of operator specific service processing is considered to be a CAMEL relationship. There are two types of CAMEL relationships: - A CAMEL control relationshi...
