for Public Warning System (MBSP)

ToC      3GPP‑Page      Help       
V14.0.0 (Wzip)    2014/12    22 p.

Rapporteur:  Mr. Hall, Edward
See also:  PWS-related TS/TR    

This TR considers enhancements to 3GPP PWS via the addition of multimedia broadcast capability. The use cases for this capability are documented and derived requirements are gathered and consolidated. This TR does not cover use cases or potential requirements for specific PWS based systems (i.e. ETWS, CMAS, EU-ALERT, and Korean Public Alert System).

This TR covers:
  • Scenarios and use cases to provide multi-media information supplemental to PWS;
  • UE awareness of, and ability to receive, multi-media information via PWS;
  • Handling of UEs in limited service mode;
  • Priority of multimedia information
