9.3.2 Usage of Private Message Mechanism for Non-standard Use
38.4233GPPNG-RANRelease 17TSXn Application Protocol (XnAP)
The private message mechanism for non-standard use may be used:
– for special operator (and/or vendor) specific features considered not to be part of the basic functionality, i.e. the functionality required for a complete and high-quality specification in order to guarantee multivendor inter-operability.
– by vendors for research purposes, e.g. to implement and evaluate new algorithms/features before such features are proposed for standardisation.
The private message mechanism shall not be used for basic functionality. Such functionality shall be standardised.
