USER EQUIPMENT, NETWORK NODE, AND BASE STATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18349644 titled 'USER EQUIPMENT, NETWORK NODE, AND BASE STATION

Simplified Explanation

This patent application describes a user equipment that can communicate with multiple mobile networks using multiple subscriber identity modules (SIM cards). The user equipment includes a memory and processors that execute a program to perform certain functions.

  • The user equipment receives a paging message from a first mobile network.
  • In response to the paging message, the user equipment transmits a SERVICE REQUEST message to an AMF (Access and Mobility Management Function).
  • The SERVICE REQUEST message includes two information elements:
 - The first information element indicates that the user equipment does not prefer to receive the paging message from the first mobile network.
 - The second information element indicates that the paging message should only be transmitted for voice service if the user equipment decides not to receive the paging message from the first network.
  • If the first information element and the second information element are transmitted, the user equipment will only receive the paging message for voice service.
