TIA Activities Supporting Wireless Alerts

David Su

Chief, Advanced Network Technologies Division



  • On October 13th, 2006, President Bush signed the Port Security Bill (HR 4954), which includes a provision for addressing a wireless Emergency Alert System (EAS). This wireless EAS provision, Warning, Alert and Response Network (WARN) Act, is an update to the EAS created in the 1960s.

  • Pursuant to the WARN ACT, the FCC established the Commercial Mobile Service Alert Advisory Committee (CMSAAC). The Committee is responsible for developing recommendations on technical standards and protocols to facilitate the ability of commercial mobile service providers to transmit emergency alerts to their subscribers.  

  • Public documents from the CMSAAC can be found on the www.fcc.gov Website.

        • Mission is “to recommend specific public alert and warning systems for inclusion into a commercial mobile service alerting capability for CMS providers that voluntarily elect to transmit emergency alerts

        • To recommend the technical fashion by which electing CMS providers can accept these alerts for distribution within their respective networks”

        • Chair Kevin Briggs, FEMA

      • Alerting Gateway Group (AGG)

        • Mission is “to develop and submit recommendations for protocols, technical capabilities and technical procedures through which CMS providers, receive, verify and transmit alerts to subscribers”

    Cmas recommendations
    CMAS Recommendations

    • Based on Broadcast Technology

    • Text-based Alerts is the Common Denominator

      • Future Streaming audio and video, multimedia optional

    • Distinguish alert messages from other text messages delivered to subscriber

    • Common Alerting Protocol (in use today by EAS) elements used for alert initiation/distribution in wireless alerts

      • CAP is not delivered to the mobile device

    • New handsets will be required

    • Other than Presidential Alerts, subscriber may opt-in/opt-out of various classes of alerts

    • Standardized alerting tone and vibrating cadence for notification of alert message

    • Support of languages, English required, other languages under consideration

    Standards impacts
    Standards Impacts

    • No standards work has been initiated, awaiting finalization of FCC recommendations/requirements.

    • Anticipate standards will be impacted

      • Possible Impacts to Cell Broadcast

      • Terminal Requirements

        • Alert Tones, Vibration Cadence

    • Several standards-setting bodies may be affected (TIA, ATIS, OMA, 3GPP, 3GPP2)

    Tia standards initiatives

    • TIA CMSAA Working Group

      • TIA established a TIA CMSAA Committee Working group to guide and represent TIA member interests in the FCC CMSAAC

        • Provides input to designated TIA representative to CSMAAC

    • TR-45 Ad-Hoc for Wireless Alert Service

      • Keep the TR-45 member companies, particularly those that are not part of the FCC effort, informed on the discussions and recommendations coming from the FCC CMSAAC

      • To address issues affecting CMRS providers and equipment suppliers and establish technical consensus positions that could be taken into the FCC CMSAAC
