Policy node, radio device and methods in a communications network

A method performed by a radio device for handling policies related to the radio device in a communications network, the radio device supporting proxy server functionality, the method comprising:

• receiving, from a policy node, a message, the message comprising:
• an indication requesting the radio device to activate the proxy server,
• one or more rules comprised in the polices, and
• a configuration related to the proxy server,
• handling policies related to the radio device by activating the proxy server in the radio device based on the received message, which proxy server enables the radio device, even though not being application aware or domain aware, to apply the one or more rules comprised in the policies related to the radio device.

A policy node configured to handle policies related to a radio device in a communications network, the radio device being adapted to support proxy server functionality, the policy node comprising processing circuitry and a memory, the processing circuitry operable to:

• during a session establishment of the radio device, determine that obtained policies adapted to be related to the radio device comprises one or more rules, wherein the respective one or more rules are adapted to comprise any one or more out of:
• an application descriptor adapted to be related to the one or more rules, and
• a domain descriptor adapted to be related to the one or more rules,
• determine, based on received capability information, that the radio device is not aware of any or more one out of an application and a domain, and that the radio device supports proxy server functionality,
• handle the policies adapted to be related to the radio device by activating a proxy server in the radio device by sending a message to the radio device, the message being adapted to comprise:
• an indication adapted to request the radio device to activate the proxy server,
• the one or more rules, and
• a configuration adapted to related to the proxy server,
• which proxy server is adapted to enable the radio device, even though not being application aware or domain aware, to apply the one or more rules comprised in the policies adapted to be related to the radio device.
