Overview

  • USSD (Unstructured Supplementary Services Data)

    • Simple interactive services for man and machine

  • Location Services (LBS, LCS)

    • Accurate positioning with GPS

  • SMS (Short Message Service)

    • Transmission of text messages or short data packets.

USSD

  • Real time exchange of text-based data between a mobile device and a network server.

  • Compatible with GSM USSD servers.

  • Mobile or network initiated.

  • Transmitted on a traffic channel or access channel.

Location Based Services (LBS)

cdma2000 Technology Workshop


Location Based Services

  • Control Plane

    • Provides position to a network application (e.g. 9-1-1).

  • User Plan

    • Uses IP to provide location to the mobile device (or network application).

Short Message Service

cdma2000 Technology Workshop


Short Message Service (SMS)

  • SMS includes text messages and various non-real-time, low bandwidth data services (such as LBS session initiation).

  • Three solutions:

    • Traditional circuit-switched SMS (ANSI-41/SS7) using C.S0015 message format.

    • Transport level mapping using IMS and C.S0015 message format.

    • Application level mapping using an instant messaging client.

  • All solutions inter-operate
