AI Technical Summary

Technical Problem

In the existing technology, the Radio Resource Control (RRC) connection and configuration procedures of dual-SIM configuration consume significant network bandwidth, resulting in increased user waiting time. In addition, existing single-SIM implementations are unable to support dual-SIM solutions and lack effective simplification or optimization solutions.

Method used

The RRC connection method with common configuration is adopted, by supporting RRC connection of the first and second SIMs in the base station and the user equipment, and providing message transmission of common configuration on the first RRC connection, thereby reducing repeated occupation of the network.

Benefits of technology

It significantly reduces the network occupancy of dual-SIM user devices, reduces network bandwidth consumption, improves connection and configuration efficiency, and reduces user waiting time.

Abstract

A single-link DSDA apparatus is disclosed. In one aspect of the disclosure, RRC connections associated with two SIMs have a common connection, and the two SIMs can be reconfigured by providing one SIM with the configuration of its RRC connection along with an indication that the other SIM is to use the common configuration for its RRC configuration. In other aspects of the disclosure, a primary SIM is established that can only perform specific tasks. In still other aspects of the disclosure, RRC connection establishment and release for a dual-SIM UE can be performed by using the primary connection to transmit the common configuration and using two connections for different configurations.
