TIA issues New Unstructured Supplementary Service Data (USSD) Service Options for Spread Spectrum Systems: Service Options 78 and 79 Standard

TIA-4968-A Specifies Requirements for Unstructured Supplementary Service Data (USSD) Service Options for Spread Spectrum Systems: Service Options 78 and 79

Arlington, VA (July 1, 2013) – The Telecommunications Industry Association, which develops standards for the information and communications technology industry, has released a new document, TIA-4968-A, Unstructured Supplementary Service Data (USSD) Service Options for Spread Spectrum Systems: Service Options 78 and 79.

TIA-4968-A revision has been issued to address technology enhancements in USSD Service Options for Spread Spectrum Systems.  The standard defines radio interface support for USSD in cdma2000^® Spread Spectrum Systems. USSD allows the Mobile Station (MS) user and a PLMN operator defined application to communicate in a way which is transparent to the MS and to intermediate network entities. The mechanism allows development of PLMN specific supplementary services.

USSD may be initiated by the MS user, or by the network. Unlike Short Message Service (SMS) messages, USSD messages create a real-time connection during a USSD session. The connection remains open, allowing a two-way exchange of a sequence of data. Several examples of how USSD Services are used include: Pre-paid balance Inquiry, Balance Transfer (payment from one’s balance to another balance), Voting (“Please rate our customer service: 1=Good, 2=OK, 3=Bad” after a call to a Customer Service Center), and Call Me (requesting another party to call you).

TIA-4968-A was formulated under the cognizance of the TIA TR-45 Mobile and Personal Communications Systems Standards, TR-45.5 Spread Spectrum Digital Technology -- Mobile and Personal Communications Standards

For more information about TR-45 and how to participate in standards development with TIA, contact Stephanie Montgomery at standards@tiaonline.org.
