CTOnews.com, August 15, according to the China Communications Standardization Association, the 25th meeting of the Mobile Communications Core Network and artificial Intelligence Application working Group (WG12) of the Wireless Communications Technology working Committee was held in Kunming from August 2 to 3, 2022. This meeting reviewed and approved the industry standard "Technical requirements for Community Broadcasting Service equipment of 5G Mobile Communication Network".

CTOnews.com learned that community broadcasting is a function in which information (such as geographical location, weather conditions, etc.) is transmitted to the mobile phone through the cell broadcast channel (CBCH), and then selected by the user to receive. Through this function, users can provide users with location information, weather forecast, early warning information and other services, and all the information received by users through the cell broadcast is free of charge.

In recent years, various departments of the state have become more and more urgent to strengthen the capacity-building of emergency early warning information for the public. The release of public early warning information through community broadcasting technology has the characteristics of timeliness and regionality, which can effectively reduce the loss of life and property caused by public emergencies to the country and the people.

The meeting reviewed and approved the industry standard Technical requirements for Cell broadcast Service equipment of 5G Mobile Communication Network, which stipulated the functional requirements, interface protocol requirements, service requirements, performance index requirements and operation and maintenance requirements of end-to-end equipment (including PWS-IWF, CBC, CBCF, AMF, gNB and UE) for cell broadcast service of 5G mobile communication network.

This standard is the first industry standard of 5G mobile communication network cell broadcasting service, which marks the initial maturity of domestic 5G mobile communication network cell broadcasting service. At the same time, the meeting also reviewed the draft of a series of industry standards for cell broadcasting, such as "Technical requirements for Cell broadcast Service equipment based on LTE Mobile Communication Network" and "Test method for Cell broadcast Service equipment of 5G Mobile Communication Network". The above series of standards will lay a solid foundation for 5G and 4G mobile communication systems to support the release of emergency early warning information.
