Privacy protection in network slice as a service

A method for wireless communication, comprising:

• authenticating, by a credential service node, a mobile device having a mobile directory number associated therewith for access to multiple network slice instances, wherein each network slice instance of the multiple network slice instances corresponds to one or more of access network network functions and one or more core network network functions in a wireless communication network;
• generating, by the credential service node, a first pseudonymous identifier of the mobile device corresponding to a first network slice instance of the multiple network slice instances;
• and
• generating, by the credential service node, a second pseudonymous identifier of the mobile device corresponding to a second network slice instance of the multiple network slice instances, the second pseudonymous identifier being different than the first pseudonymous identifier,
• wherein the first pseudonymous identifier is different from the second pseudonymous identifier,
• wherein the first pseudonymous identifier is used in place of the mobile directory number for communications associated with the first network slice instance,
• wherein the second pseudonymous identifier is used in place of the mobile directory number for communications associated with the second network slice instance,
• wherein the first pseudonymous identifier is associated with a first level of anonymity,
• wherein the second pseudonymous identifier is associated with a second level of anonymity, the second level different from the first level,
• wherein the first pseudonymous identifier does not include the mobile directory number,
• wherein the second pseudonymous identifier does not include the mobile directory number,
• wherein the first pseudonymous identifier cannot be determined to be associated with a user of the mobile device without additional information,
• wherein the second pseudonymous identifier cannot be determined to be associated with the user of the mobile device without additional information,
• wherein the first pseudonymous identifier and the second pseudonymous identifier are generated based at least in part on subscription information comprising a level of desired privacy protection.

A method for wireless communication, comprising:

• registering with a credential service node by a user device having a mobile directory number associated therewith to be authenticated for access to multiple network slice instances, wherein each of the multiple network slice instances corresponds to one or more of access network functions and one or more core network functions in a wireless communication network;
• obtaining, by the user device from the credential service node, a first pseudonymous identifier of the user device corresponding to a first network slice instance of the multiple network slice instances;
• performing, by the user device, communication using the first network slice instance using the first pseudonymous identifier,
• obtaining, by the user device from the credential service node, a second pseudonymous identifier of the user device corresponding to a second network slice instance of the multiple network slice instances, the second pseudonymous identifier being different than the first pseudonymous identifier;
• and
• performing, by the user device, communication using the second network slice instance using the second pseudonymous identifier,
• wherein the first pseudonymous identifier is different from the second pseudonymous identifier,
• wherein the first pseudonymous identifier is used in place of the mobile directory number for communications associated with the first network slice instance,
• wherein the second pseudonymous identifier is used in place of the mobile directory number for communications associated with the second network slice instance,
• wherein the first pseudonymous identifier is associated with a first level of anonymity,
• wherein the second pseudonymous identifier is associated with a second level of anonymity, the second level different from the first level,
• wherein the first pseudonymous identifier does not include the mobile directory number,
• wherein the second pseudonymous identifier does not include the mobile directory number,
• wherein the first pseudonymous identifier cannot be determined to be associated with a user of the mobile device without additional information,
• wherein the second pseudonymous identifier cannot be determined to be associated with the user of the mobile device without additional information,
• wherein the first pseudonymous identifier and the second pseudonymous identifier are generated based at least in part on subscription information comprising a level of desired privacy protection.
