AI Technical Summary

Technical Problem

In the timer service scenario, the application network element cannot obtain the end-to-end time synchronization error information of the terminal, resulting in the inability to determine whether the delay requirement is met.

Method used

By determining in the access network device whether the end-to-end time synchronization error of the terminal meets the requirements of the timing service, and sending corresponding information to the application network element, it indicates the process of performing the deactivate or modifying the timing service.

Benefits of technology

Enable application network elements to obtain end-to-end time synchronization error information of the terminal in a timely manner, so as to promptly execute necessary business processes, avoid affecting the continuity of timed service, and reduce information interaction processes and signaling overhead.

Abstract

The present application provides a communication method and a communication apparatus, can enable an application network element to obtain information that an end-to-end time synchronization error corresponding to a terminal does not meet the end-to-end time synchronization error requirements of a timing service, and can be applied to a communication system. The method comprises: an access network device determines that an end-to-end time synchronization error corresponding to a terminal does not meet the end-to-end time synchronization error requirements of a timing service; and the access network device sends first information to an application network element, wherein the first information is used for indicating that the end-to-end time synchronization error corresponding to the terminal does not meet the end-to-end time synchronization error requirements of the timing service, and the first information is used for the application network element to determine to execute the process of deactivating the timing service or the process of modifying the timing service.
