From Wikipedia, the free encyclopedia

3G-324M is the 3GPP umbrella protocol for video telephony in 3G mobile networks.

The 3G-324M protocol operates over an established circuit switched connection between two communicating peers. 3G-324M is an umbrella specification to enable conversational multimedia communication over Circuit Switched (CS) networks and has been adopted by the 3GPP. 3G-324M is based on the ITU-T H.324 specification for multimedia conferencing over Circuit switched networks. 3G-324M is composed of the following sub-protocols:

  • ITU-T H.245 for call control
  • ITU-T H.223 for bit streams to data packets multiplexer/demultiplexer
  • ITU-T H.223 Annex A and B for error handling of low and medium BER detection, correction and concealment
  • ITU-T H.324 with Annexes A and C for operating in wireless environment

The 3G-324M specification using the Circuit switched network allows delay sensitive conversational multimedia services such as:

  • Video Conferencing for personal and business use
  • Multimedia entertainment services
  • Telemedicine
  • Surveillance
  • Live Video Broadcasting– Cable TV On-the-Go
  • Video-on-demand (movies, news clips)

3G-324M is agnostic to the actual Circuit switched network that uses it. It can run as easily over UMTS as well as TD-SCDMA networks.

3G-324M is a proven solution for conversational multimedia based services that packet-based wireless networks cannot deliver because of inherent overhead, BER sensitivity, and variant routing delays. 3G-324M operating over a circuit switched channel between two communication peers guarantees the fixed-delay quality of service for multimedia communications. Combining Circuit switched 3G-324M services with packet-based SIP services such as presence can leverage the strength of both networks to enable new types of differentiated and innovative mobile 3G services.
