COMMUNICATION APPARATUS, AND COMMUNICATION METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18515888 titled 'COMMUNICATION APPARATUS, AND COMMUNICATION METHOD

Simplified Explanation

The communication apparatus described in the patent application is designed to communicate with multiple networks using multiple subscriber identity modules. It includes a communicator and a controller that work together to manage the transition of a radio resource management (RRC) state.

  • The communicator receives information from a network to set a timer for RRC state transition and sends information back to indicate the RRC state transitioning.
  • The controller starts the timer upon receiving the second information and transitions the RRC state to an RRC idle state when the timer expires.

Potential Applications

This technology could be applied in:

  • Mobile communication devices
  • Internet of Things (IoT) devices

Problems Solved

This technology helps in:

  • Efficient management of radio resources
  • Seamless transition between RRC states

Benefits

The benefits of this technology include:

  • Improved network efficiency
  • Enhanced user experience with smoother transitions

Potential Commercial Applications

Optimizing RRC state transitions for:

  • Mobile network operators
  • IoT device manufacturers

Unanswered Questions

How does this technology impact battery life in mobile devices?

The patent application does not address the potential impact on battery life due to the management of RRC states.

Are there any compatibility issues with existing network infrastructures?

The patent application does not mention any potential compatibility issues with current network setups.


Original Abstract Submitted

A communication apparatus configured to communicate with a plurality of networks by using a plurality of subscriber identity modules comprises a communicator and a controller. The communicator is configured to receive, from a network included in the plurality of networks, first information for setting a value of a timer relating to transition of a radio resource management (RRC) connected state, and transmit, to the network, second information to be used to indicate an RRC state transitioning from the RRC connected state. The second information can indicate an RRC inactive state as the RRC state. The controller is configured to start the timer on the basis of transmission of the second information, and cause the RRC state to transition to an RRC idle state on the basis of expiration of the timer.
