TECHNIQUES FOR MANAGING SUBSCRIPTION IDENTIFICATION FOR EMERGENCY CALL - A simplified explanation of the abstract

This abstract first appeared for US patent application 18351382 titled 'TECHNIQUES FOR MANAGING SUBSCRIPTION IDENTIFICATION FOR EMERGENCY CALL

Simplified Explanation

The patent application discusses a method for a mobile device to make emergency calls when equipped with multiple service subscriptions in a cellular communication system.

  • The mobile device can have multiple User Services Identity Modules (USIMs) to support multiple service subscriptions.
  • The device can obtain services from one or more wireless networks with each of the subscriptions.
  • When the device needs to make an emergency call, it needs to identify and determine which service subscription to use for the call.
  • The device is implemented with a communication processor (modem) and an application processor (AP).
  • Some information necessary to identify the most suitable service subscription for the emergency call may only be available at the communication processor.
  • The patent application discloses enhanced techniques for the communication processor and the application processor to interact and determine the appropriate service subscription for the emergency call.


Original Abstract Submitted

A UE in cellular communication system may be equipped with multiple User Services Identity Modules (USIMs) to support multiple service subscriptions. The UE having multiple service subscriptions may obtain services from one or more wireless networks with each of the subscriptions. When the UE having multiple service subscriptions needs to make an emergency call, the UE may identify and determine a service subscription to make the emergency call, so that the emergency call can be successfully made. The UE may be implemented with a communication processor (modem) and an application processor (AP). Some information that is useful to identify a service subscription more suitable for the emergency call may be available only at the communication processor. Enhanced techniques for identifying and determining a service subscription to make the emergency call from the multiple service subscriptions through interaction between the communication processor and the application processor are disclosed.
