METHOD AND APPARATUS FOR NETWORK SECURITY - A simplified explanation of the abstract

This abstract first appeared for US patent application 17904007 titled 'METHOD AND APPARATUS FOR NETWORK SECURITY

Simplified Explanation

The abstract describes a method for a user equipment (UE) in a communication network to handle emergency protocol data unit (PDU) sessions. The method involves transmitting a control plane service request (CPSR) message to an AMF entity, receiving a security mode command message indicating a failed integrity check for the CPSR message, and then identifying whether the CPSR message includes certain types of data or not. Based on this identification, the UE transmits the CPSR message excluding certain types of data.

  • The method is designed for a pre-5G or 5G communication system.
  • It supports higher data rates beyond the 4G LTE system.
  • The method is specifically focused on handling emergency PDU sessions in idle mode.
  • The UE identifies the presence of certain types of data in the CPSR message.
  • The UE excludes certain types of data from the CPSR message when transmitting it.

Potential Applications

  • This method can be applied in emergency communication systems to ensure efficient handling of emergency PDU sessions.
  • It can be used in public safety networks to improve the reliability and effectiveness of emergency communication.

Problems Solved

  • The method addresses the challenge of handling emergency PDU sessions in idle mode in a pre-5G or 5G communication system.
  • It solves the problem of failed integrity checks for CPSR messages by identifying and excluding certain types of data.

Benefits

  • The method allows for the efficient transmission of CPSR messages in emergency situations.
  • It ensures the integrity of the communication system by identifying and excluding potentially problematic data.
  • The method improves the overall reliability and performance of emergency communication systems.


Original Abstract Submitted

The present disclosure may be related to a pre-5G or 5G communication system to be provided for supporting higher data rates Beyond 4G communication system such as LTE. A method, for a UE in a network comprising the UE and an AMF entity, is disclosed. The method comprises: identifying that the UE in idle mode, has an emergency protocol data unit (PDU) session, transmitting, to the AMF, a control plane service request (CPSR) message comprising data of a first type, receiving, from the AMF, a security mode command message indicating that an integrity check related to the CPSR message has failed, in response to receiving the security mode command message, identifying whether the CPSR message comprises the data of the first type including data of a second type, or the CPSR message comprises the data of the first type excluding the data of the second type, and transmitting the CPSR message excluding the data of the first type except the data of the second type.
