The contents of the present document are subject to continuing work within the TSG and may change following formal TSG

44、 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 where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approva

45、l; 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 is incremented when editorial only changes have been incorporated in the document.

46、 TR 133 969 V15.0.0 (2018-07)83GPP TR 33.969 version 15.0.0 Release 151 Scope The present document studies security features and mechanisms for protection against false Base Stations broadcasting False Warning Notifications. The default terminal behaviour is to accept all Warning Notifications even

47、if their authenticity is unknown (i.e. no security protection). The default terminal behaviour is therefore open to the presentation of false Warning Notifications issued by false BSs even in countries without a Public Warning System (PWS) deployed. Examples of false BS risks include, but are not li

48、mited to: g882 False Warning Notifications to induce panic; g882 Abuse of warning system broadcast channel to send advertising / spam.
