METHODS TO ESTABLISH A PROTOCOL DATA UNIT SESSION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17997357 titled 'METHODS TO ESTABLISH A PROTOCOL DATA UNIT SESSION

Simplified Explanation

The patent application describes methods, systems, and devices for wireless communications. It focuses on a user equipment (UE) operating in a dual-subscription mode with a first and second subscription. The UE has an application that wants to establish a data connection based on an access preference rule for the application.

  • The UE identifies that it is in dual-subscription mode with a first and second subscription.
  • The UE's application requests a data connection based on an access preference rule.
  • The UE determines that the access preference rule does not match any policies in the first subscription's route selection policy.
  • The UE evaluates the second subscription's route selection policy to find a matching policy for the access preference rule.
  • After finding a matching policy in the second subscription's route selection policy, the UE establishes the data connection.

Potential Applications

  • Dual-SIM smartphones or devices with multiple subscriptions can benefit from this technology.
  • Applications that require specific network access preferences can utilize this method to establish data connections.

Problems Solved

  • The technology solves the problem of efficiently establishing data connections in dual-subscription mode.
  • It addresses the issue of access preference rules not matching any policies in the default subscription's route selection policy.

Benefits

  • Users can have more control over their network access preferences in dual-subscription mode.
  • Applications can establish data connections based on their specific access preference rules.
  • Improved efficiency in establishing data connections in dual-SIM devices.


Original Abstract Submitted

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that it is operating in a dual-subscription mode that includes a first subscription and a second subscription. In some cases, the UE may include an application that is requesting to establish a data connection in accordance with an access preference rule for the application. The UE may determine that the access preference rule lacks a match among policies of a first route selection policy associated with the first subscription (e.g., a default subscription). The UE may then evaluate a second route selection policy associated with the second subscription for a policy that matches the access preference rule based on determining the lack of the match among policies of the first route selection policy. The UE may establish the data connection after evaluating the second route selection policy for the matching policy.
