AI Technical Summary
When a full-block fault occurs in the voice PCF network element, the existing technology lacks an active escape path for voice services, resulting in continuous failures to establish voice services on user terminals and severely impacting user experience.
The data PCF network element receives the policy control session creation request sent by the SMF network element, and establishes the first policy control session with the SMF network element based on the IP Multimedia Subsystem Access Point Name and the pre-configured voice policy to take over the voice service of the user terminal and achieve smooth voice service takeover.
This effectively avoids prolonged interruptions to user terminal voice services caused by PCF network element failures, enhances the disaster recovery capability and high reliability of the core network system, and ensures the user's communication experience.
