Title:
METHOD AND APPARATUS FOR UPDATING NETWORK SUPPORT FOR IMS DC CAPABILITY TO UE AFTER INITIAL REGISTRATION IN A WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/214853
Kind Code:
A1
Abstract:
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein provide a method for updating IMS DC capability to a UE after an initial registration in a wireless network (1000) by the UE (100). The method includes sending a REGISTRATION request message indicating a UE support for the IMS DC capability to a network apparatus (200). Further, the method includes receiving a REGISTRATION ACCEPT message indicating that the network apparatus does not support the IMS DC capability from network apparatus. Further, the method includes storing the IMS DC capability as not supported in a memory (130) of the UE and discard initiating a DC session with the network apparatus. In an embodiment, method includes receiving an indication from the network apparatus indicating that the network apparatus is enhanced to support for the IMS DC capability, and updating a stored network IMS DC capability from not supported to supported and allow initiating a DC session with the network apparatus.
