Methods, nodes and operator network for enabling filtering of traffic from an application

A method, performed by an application node hosting an application, for enabling filtering of traffic from the application towards a user equipment, the method comprising:

• transmitting, towards a policy node, application content information relating to the filtering of the traffic and an identifier of the application to which the application content information applies, wherein the application content information comprises an indication relating to application content category and one or more of:
• an adaptability indicator specifying whether the application is able to adapt the traffic to a given user content category;
• and
• a notification indicator specifying whether the application is able to notify, to the policy node, an application content category before providing requested traffic.

A policy node configured for enabling filtering of traffic from an application hosted by an application node towards a user equipment, the policy node is being configured to:

• receive, from the application node, application content information relating to the filtering of the traffic and an identifier of the application to which the application content information applies, the application content information comprising an indication relating to application content category of the traffic, and the application content information comprising one or more of:
• an adaptability indicator specifying whether the application is able to adapt the traffic to a given user content category;
• and
• a notification indicator specifying whether the application is able to notify, to the policy node, an application content category before providing requested traffic;
• and
• transmit, to a storage node, the application content information.
