USER EQUIPMENT AND CALL RECOVERY METHOD EXECUTED BY THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18084061 titled 'USER EQUIPMENT AND CALL RECOVERY METHOD EXECUTED BY THE SAME

Simplified Explanation

The abstract describes a patent application for a user equipment and a call recovery method. The method involves determining if a PDU session is activated in the user equipment and an AMF based on PDU session information. It also determines if there is no DRB for bearing IMS signaling based on radio bearer configuration information. If these conditions are met, the method requests the base station to re-transmit the radio bearer configuration information.

  • The patent application is for a user equipment and a call recovery method.
  • The method involves determining if a PDU session is activated in the user equipment and an AMF.
  • It also determines if there is no DRB for bearing IMS signaling.
  • If the conditions are met, the method requests the base station to re-transmit the radio bearer configuration information.

Potential Applications

  • This technology can be applied in telecommunications networks.

Problems Solved

  • The technology solves the problem of call recovery in the event of a failure or interruption.
  • It addresses the issue of missing DRB for bearing IMS signaling.

Benefits

  • The technology ensures that calls can be recovered and communication can continue seamlessly.
  • It improves the reliability and quality of telecommunications services.


Original Abstract Submitted

A user equipment and a call recovery method executed by the user equipment are provided. The call recovery method executed by the user equipment includes: determining whether a protocol data unit PDU session is activated in the user equipment UE and an access mobility management function entity AMF based on PDU session information, and determining whether there is no data radio bearer DRB for bearing International protocol multimedia subsystem IMS signaling based on radio bearer configuration information; and requesting a base station gNB to re-transmit the radio bearer configuration information including the DRB for bearing the IMS signaling if the PDU session is activated in the UE and the AMF and there is no DRB for bearing the IMS signaling.
