Method for managing emergency wireless sessions by conditionally disabling user plane security protections based on emergency indicators and null ciphering detection.

Patentradars sammanfattning

This patent describes a method for a core network (CN) node to determine user plane (UP) security activation for wireless devices during emergency sessions. Upon receiving a UP session establishment request with an indication of emergency status or null ciphering/integrity protection on the control plane, the CN node determines whether to configure the UP without activating integrity and confidentiality protection, then provides this security policy to the radio access network (RAN) node. This approach allows flexibility in security posture during critical emergency communications.
