The contents of the prese
30、nt document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the present document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z
31、 where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit
32、 is incremented when editorial only changes have been incorporated in the document. Introduction Although network nodes in the IMS Core Network should have a very high availability, some maintenance downtime and occasional failures are unavoidable. Communication links although designed with robust p
33、rotocols between the network elements are also subject to failures. This document specifies a set of standardized procedures for automatic restoration after loss or corruption of data reducing the impact of these problems in order to improve service to the users. The scenarios covered here for the I
34、MS Domain are similar to those covered in 3GPP TS 23.007 2 for the CS and PS Domains. ETSI ETSI TS 123 380 V13.2.0 (2016-04)63GPP TS 23.380 version 13.2.0 Release 131 Scope The present document specifies the procedures required in 3GPP IMS to handle a S-CSCF or a P-CSCF service interruption scenario
35、 with minimum impact to the service to the end user. NOTE: IMS Restoration Procedures covering service interruption of other network elements are not defined in this version of the specification. 2 References The following documents contain provisions which, through reference in this text, constitut
36、e provisions of the present document. References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific.
