RRC CONFIGURATION FOR SINGLE LINK, DUAL SUBSCRIBER IDENTITY MODULE DUAL ACTIVE (DSDA): abstract simplified (18005925)

The abstract describes a Single-Link DSDA (Dual SIM Dual Active) apparatus. It explains that the apparatus allows for the reconfiguration of RRC (Radio Resource Control) connections associated with two SIM cards. One SIM card is provided with its own RRC configuration, while the other SIM card uses a common configuration for its RRC connection. The abstract also mentions the establishment of a primary SIM card that can only perform certain tasks. Additionally, it states that the RRC connection establishment and release for a dual-SIM device can be done by using the primary connection to send a common configuration and utilizing both connections for different configurations.
