METHODS PROVIDING MANAGEMENT OF EMERGENCY SESSIONS AND RELATED DEVICES AND NODES - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18203523 Titled 'METHODS PROVIDING MANAGEMENT OF EMERGENCY SESSIONS AND RELATED DEVICES AND NODES'
Simplified Explanation
This abstract describes a method for operating a CN (Core Network) node to determine the activation of UP (User Plane) security. When a request is received to establish a UP session for a wireless device, the CN node checks if the request is related to an emergency session and if null ciphering and/or null integrity protection are applied to a CP (Control Plane) session associated with the wireless device. Based on this information, the CN node determines whether UP should be configured for the session without activating integrity and/or confidentiality protection. A UP security policy is then provided to a RAN (Radio Access Network) node, instructing it to configure the UP session accordingly.
Original Abstract Submitted
A method is provided to operate a CN node to determine UP security activation. A UP session establishment request is obtained for a wireless device. An indication is obtained that the UP session establishment request is associated with an emergency session and/or that null ciphering and/or null integrity protection are applied to a CP associated with a CP session for the wireless device. It is determined that a UP should be configured for the UP session without activating integrity and/or confidentiality protection for the UP based on the indication. A UP security policy is provided to a RAN node associated with the wireless device, wherein the UP security policy indicates to configure the UP for the UP session without activating integrity and/or confidentiality protection based on determining that a UP should be configured for the UP session without activating integrity and/or confidentiality protection.
