Method and network node for implementing user defined policies based on device subscription identifiers in a telecommunication network

A network node comprising communication circuitry configured for transmitting from an antenna array, and processing circuitry operatively associated with the communication circuitry and configured to:

• receive a policy information request from a device comprising a subscription identifier, SID, linked to the device identifying a subscription, wherein a set of two or more policies are linked to the SID and one of the policies included in the set of policies is set as an active policy for the subscription, and wherein each policy is associated with a different user identifier, UID, the policies offering user specific policies and comprising user specific service authorizations under the subscription in the communication network;
• after receiving the policy information request comprising the SID, determine the policy that is set as the active policy for the subscription identified by the SID, determining the policy that is set as the active policy comprising determining a UID that is set as an active UID for the subscription and determining the UID that is set as the active UID comprising parsing the policy information request to obtain the active UID;
• obtain the active policy from a data base;
• in response to the policy information request, transmit a policy information response to the device comprising the obtained active policy;
• receive a first request to register a particular user, the request comprising the SID and a particular UID assigned to the user;
• after receiving the first request, add the particular UID to a set of UIDs linked with the SID;
• receive a second request to set a policy for the particular user, the request comprising the SID, the particular UID assigned to the user, and a particular user defined policy for the particular user;
• and
• after receiving the second request, store the particular user defined policy so that the particular user defined policy is linked with the particular UID.
