Methods and systems for managing bearer configuration of user equipment with en-dc capability

Abstract

The present disclosure relates to a communication method and system for converging a 5-Generation (5G) communication system for supporting higher data rates beyond a 4-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Methods and systems for managing bearer configuration of user equipment (UE) with Evolved-Universal Terrestrial Radio Access Network-New Radio-Dual Connectivity (E-UTRAN-NR-DC) (EN-DC) capability. The UE detects connectivity issues in the UE itself and in interfaces connecting between a NR network with the UE, a LTE network, or an EPC that require disabling NR capability of the UE. The bearer configuration is determined and updated based on the detected connectivity issues. The UE signals the LTE network about the disabling of NR capability, requests enabling of data transfer through bearers of a MCG bearers associated with the LTE network in a current MCG RRC session, and prevents addition of SCG bearers associated with the NR network. The UE recovers data in the SCG bearers, lost due the issues in the NR network, through the MCG bearers. The UE can send a Tracking Area Update (TAU) to indicate the disabling of NR capability if the connectivity issues persist.
