Prioritizing Random Access Procedures for Mobile Terminated Access Attempts in Paging Message (18033467)

Main Inventor

Malgorzata Tomala

Brief explanation

The abstract of this patent application describes a method for a user equipment (UE) in a wireless system to receive and apply random-access priority information. When a random access is triggered, the UE uses the random-access priority received in a paging message. The network node in the wireless system generates this random-access priority information for the UE to use during a random-access procedure.

• The UE receives random-access priority information in a paging message.
• When a random access is triggered, the UE applies the random-access priority received in the paging message.
• The network node in the wireless system generates the random-access priority information for the UE.
• The network node sends the random-access priority information to the UE in a paging message.

Potential Applications

• This technology can be applied in various wireless systems, such as cellular networks, to improve the efficiency of random-access procedures.
• It can be used in IoT networks to prioritize random access requests from different devices based on their assigned random-access priority.

Problems Solved

• Prioritizing random access requests in wireless systems can be challenging without a standardized method.
• Without the random-access priority information, the UE may not be able to efficiently handle random-access procedures.

Benefits

• The UE can prioritize its random access requests based on the received random-access priority information, leading to improved system efficiency.
• The network node can assign different random-access priorities to UEs based on their requirements or importance, allowing for better resource allocation and management.

Abstract

A UE receives, in a paging message, information corresponding to random-access priority. The UE applies, in response to a random access being triggered, the random-access priority according to the information received in the paging message. A network node in a wireless system generates information corresponding to random-access priority for a UE to use for a random-access procedure. The network node sends, in a paging message, information corresponding to the random-access priority toward the user equipment.
