AI Technical Summary
Dual SIM dual standby (DSDS) terminal devices experience unexpected disconnection of RRC connections when one SIM card is in an RRC connected state and the other SIM card needs to perform data transmission, leading to user experience issues and ping-pong handover between RRC connections.
A wireless communication method where a terminal device sends a message to an access network device to request the establishment or resumption of an RRC connection with a second subscriber identity, including auxiliary information to determine the release or deactivation of the first RRC connection, thereby optimizing RRC connection handover and reducing signaling overheads.
The solution avoids unexpected disconnection of RRC connections, ensures user experience by maintaining stable data transmission, and reduces ping-pong handover between RRC connections by allowing for efficient RRC connection management.
