Abstract:

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.
