User Equipment Having Multiple Subscriber Identity Modules with Improved Suspend / Resume Operation

This abstract first appeared for US patent application 20240197942 titled 'User Equipment Having Multiple Subscriber Identity Modules with Improved Suspend / Resume Operation

Simplified Explanation

The patent application describes devices and methods for operating a dual-SIM dual-standby user equipment device with two SIM cards. The device can switch between cellular networks to prioritize higher priority communications.

The user equipment device can communicate with a cellular network using one SIM card while receiving a request to use the other SIM card for a higher priority communication.
In response to the request, the device sends a request to suspend the current connection with the first network.
After receiving a message from the network to place the connection in an inactive state, the device initiates a timer to determine the state of the connection.

Original Abstract Submitted

devices and associated methods for operating a dual-subscriber identity module (sim) dual-standby (dsds) user equipment device (ue) configured with a first sim and a second sim. the ue performs communications with a first cellular network using the first sim and a first radio resource control (rrc) connection, and receives a request to perform a higher priority communication using the second sim. in response to the request to perform the higher priority communication, the ue transmits a request to the first network to suspend the first rrc connection. after transmission of the request to suspend the first rrc connection, the ue receives a message from the first network to place the first rrc connection in an inactive state, and initiates a timer, wherein the timer is used to determine whether the first rrc connection remains in the inactive state or transitions to an idle state.
