METHOD AND DEVICE FOR SUPPORTING VOICE HANDOVER IN WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 17995844 titled 'METHOD AND DEVICE FOR SUPPORTING VOICE HANDOVER IN WIRELESS COMMUNICATION SYSTEM

Simplified Explanation

The present disclosure is about a method and device for supporting voice handover in a wireless communication system, specifically in a 5G or pre-5G system. The aim is to increase service quality and support higher data transmission rates compared to 4G systems like LTE.

  • The method involves a UE (User Equipment) connected to a first network communicating with a second network in a wireless communication system.
  • The UE connects a voice call to the second network using circuit switching (CS).
  • The base station of the second network sends a message to the UE, which includes control information for controlling wireless access of the UE.
  • The UE uses the control information to determine the radio access technology (RAT) and the Public Land Mobile Network (PLMN) to be used after the voice call is completed.
  • The first network and the second network use different RATs for communication.

Potential applications of this technology:

  • Enhanced voice call handover in 5G or pre-5G communication systems.
  • Improved service quality and higher data transmission rates for voice calls.
  • Seamless transition between different networks and RATs during voice calls.

Problems solved by this technology:

  • Ensures smooth handover of voice calls between different networks and RATs.
  • Provides a method for controlling wireless access and determining the appropriate RAT and PLMN for the UE after the voice call.
  • Addresses the need for higher data transmission rates and improved service quality in 5G or pre-5G communication systems.

Benefits of this technology:

  • Enhanced user experience with improved voice call quality and reliability.
  • Efficient utilization of different networks and RATs for seamless communication.
  • Supports higher data transmission rates, enabling faster and more reliable voice calls in 5G or pre-5G systems.


Original Abstract Submitted

The present disclosure relates to a 5G or pre-5G communication system for supporting higher data transmission rates than 4G communication systems such as LTE. The present invention relates to a method and device for supporting voice handover in a wireless communication system and increasing service quality in a mobile communication system, and more specifically, to a method for a UE connected to a first network to communicate with a network in a wireless communication system, the method comprising the steps of: connecting a voice call to a second network; receiving, from a base station of the second network, a message including control information for controlling wireless access of the UE; and using the control information to determine the radio access technology (RAT) to be used and the PLMN to be accessed after the voice call is completed, wherein the first network and the second network communicate using different RATs, and the voice call is connected to the second network by circuit switching (CS).
