INITIATION OF SECONDARY AUTHENTICATION FOR A SUBSCRIBER ENTITY

Abstract

There is provided techniques for initiating a secondary authentication process for a subscriber entity. A method is performed by a UPF entity. The method includes monitoring user plane traffic of an already established PDU session for the subscriber entity. The user plane traffic is monitored for a request from the subscriber entity to access an application service of a data network. Observing the request triggers the UPF entity to initiate the secondary authentication process for the subscriber entity for allowing the subscriber entity to access the application service. The method includes sending a notification to an SMF entity to initiate the secondary authentication process for the subscriber entity upon having observed the trigger.
