Future-proof privacy

A wireless device comprising:

• communication circuitry configured to send uplink signals to a network node in a Home Network (HN) and receive downlink signals from the network node;
• and
• one or more processing circuits configured to:
• obtain a priority list defining a different priority for each of a plurality of parameter sets, wherein each parameter set is different from a null parameter set and comprises one or more parameters used for calculating a subscription identifier identifying a subscription of the wireless device;
• calculate the subscription identifier using a parameter set selected from among the plurality of parameter sets and the null parameter set, the parameter set being selected responsive to the defined priorities;
• and
• inform the HN of the subscription of the wireless device by sending the calculated subscription identifier to a network node in the HN.

A non-transitory computer program product stored in a non-transitory computer readable medium for controlling a wireless device in communication with a network node in a Home Network (HN), the computer program product comprising software instructions, which, when run on at least one processing circuit in the wireless device, causes the wireless device to:

• obtain a priority list defining a different priority for each of a plurality of parameter sets, wherein each parameter set is different from a null parameter set and comprises one or more parameters used for calculating a subscription identifier identifying a subscription of the wireless device;
• calculate the subscription identifier using a parameter set selected from among the plurality of parameter sets and the null parameter set, the parameter set being selected responsive to the defined priorities;
• and
• inform the HN of the subscription of the wireless device by sending the calculated subscription identifier to a network node in the HN.
