The present document identifies the 3GPP system specifications for Release 17. The specifications and reports of this Release have a major version number 17 (i.e. 17.x.y). The listed Specifications are required to build a system based on the Evolved Packet System.
The high-level architecture of such a system is defined in TS 23.002 (Figure 1b).
The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
References are either specific (identified by date of publication, edition number, version number, etc.) or non specific.
For a specific reference, subsequent revisions do not apply.
For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.
