The regulator system (24) is configured to receive, from either an operator system (10) of a wireless communication network operator or an enterprise system of an enterprise, a record that includes information about administration of a subscription identifier associated with the wireless communication network operator. The regulator system (24) is also configured to verify whether administration of the subscription identifier as indicated by the record conforms to one or more rules (34) governing administration of subscription identifiers. The regulator system (24) is further configured to, depending on the verification, approve or reject the record for addition to a permissioned distributed database (26) (e.g., a permissioned blockchain) that is distributed at least in part between the regulator system (24) and either the operator system (10) or the enterprise system. ## Claims ### Claim 1 A method performed by a regulator system of a regulator for regulating administration of subscription identifiers associated with a wireless communication network, the method comprising: receiving, by the regulator system from either an operator system of a wireless communication network operator or an enterprise system of an enterprise, a record that includes information about administration of a subscription identifier associated with the wireless communication network operator; verifying, by the regulator system, whether administration of the subscription identifier as indicated by the record conforms to one or more rules governing administration of subscription identifiers, said verifying comprising determining whether the subscription identifier: has been administered with only one end user or end device in conformance with the one or more rules; and/or is within a set of subscription identifiers that is administrable according to the one or more rules; and/or has been administered within a time period that conforms to the one or more rules; and depending on said verifying, the regulator system approving or rejecting the record for addition to a permissioned blockchain database that is distributed at least in part between the regulator system and either the operator system or the enterprise system. ### Claim 2 (depends on 1) The method of claim 1, wherein said verifying comprises verifying whether the subscription identifier has been administered with a format that conforms to the one or more rules. ### Claim 3 (depends on 1) The method of claim 1, wherein the information in the record indicates the subscription identifier. ### Claim 4 (depends on 1) The method of claim 1, further comprising analyzing, by the regulator system and based on multiple records included in the permissioned blockchain database, whether subscription identifiers associated with the wireless communication network operator have been administered in conformance with the one or more rules. ### Claim 5 (depends on 1) The method of claim 1, wherein the permissioned blockchain database includes a regulator tier and an operator tier, wherein a set of one or more regulator-tier records in the regulator tier includes information associated with the wireless communication network operator and is linked to a set of one or more operator-tier records in the operator tier that includes the information about administration of subscription identifiers associated with the wireless communication network operator, and wherein the received record is an operator-tier record received from the operator system. ### Claim 6 (depends on 5) The method of claim 5, wherein the operator tier, but not the regulator tier, is distributed between the regulator system and the operator system. ### Claim 7 (depends on 5) The method of claim 5, wherein the set of one or more regulator-tier records comprises information indicating a home network identity (HNI) assigned to the wireless communication network operator. ### Claim 8 (depends on 5) The method of claim 5, wherein the set of one or more regulator-tier records comprises information indicating whether or not subscription identifiers associated with the wireless communication network operator are administrable. ### Claim 9 (depends on 5) The method of claim 5, wherein the set of one or more regulator-tier records comprises information associated with a contract between the regulator and the wireless communication network operator. ### Claim 10 (depends on 5) The method of claim 5, wherein the set of one or more regulator-tier records comprises information indicating one or more sets of subscription identifiers that the wireless communication network operator is permitted to administer. ### Claim 11 (depends on 5) The method of claim 5, wherein the set of one or more regulator-tier records comprises information indicating one or more frequency spectrum ranges in which the wireless communication network operator is permitted to operate. ### Claim 12 (depends on 1) The method of claim 1, wherein the permissioned blockchain database includes a regulator tier, an operator tier, and an enterprise tier, wherein a set of one or more regulator-tier records in the regulator tier includes information associated with the wireless communication network operator, wherein the set of one or more regulator-tier records is linked to a set of one or more operator-tier records in the operator tier, wherein the set of one or more operator-tier records includes information associated with one or more enterprises to which the wireless communication network operator has delegated administration of respective sets of subscription identifiers, wherein the set of one or more operator-tier records is linked to a set of one or more enterprise-tier records in the enterprise tier, wherein the set of one or more enterprise-tier records includes the information about administration of subscription identifiers as delegated by the wireless communication network operator to the one or more enterprises, and wherein the received record is an enterprise-tier record received from the enterprise system of the enterprise to which the wireless communication network operator has delegated administration of the subscription identifier. ### Claim 13 (depends on 1) The method of claim 1, wherein said verifying comprises the determining of whether the subscription identifier has been administered with only one end user or end device in conformance with the one or more rules. ### Claim 14 (depends on 1) The method of claim 1, wherein said verifying comprises the determining of whether the subscription identifier is within a set of subscription identifiers that is administrable according to the one or more rules. ### Claim 15 (depends on 1) The method of claim 1, wherein said verifying comprises the determining of whether the subscription identifier has been administered within a time period that conforms to the one or more rules. ### Claim 16 (depends on 1) The method of claim 1, wherein the information in the record indicates a set of subscription identifiers that includes the subscription identifier. ### Claim 17 (depends on 1) The method of claim 1, wherein the information in the record indicates whether and/or when the subscription identifier was assigned to an end user or end device. ### Claim 18 (depends on 1) The method of claim 1, wherein the information in the record indicates whether and/or when the subscription identifier was activated for working use. ### Claim 19 A regulator system of a regulator for regulating administration of subscription identifiers associated with a wireless communication network, regulator system comprising: communication circuitry configured to communicatively connect the regulator system to an operator system of a wireless communication network operator and/or to an enterprise system of an enterprise; and processing circuitry configured to: receive, via the communication circuitry and from either the operator system or the enterprise system, a record that includes information about administration of a subscription identifier associated with the wireless communication network operator; verify whether administration of the subscription identifier as indicated by the record conforms to one or more rules governing administration of subscription identifiers, wherein to verify the processing circuitry is configured to determine whether the subscription identifier: has been administered with only one end user or end device in conformance with the one or more rules; and/or is within a set of subscription identifiers that is administrable according to the one or more rules; and/or has been administered within a time period that conforms to the one or more rules; and depending on said verifying, approve or reject the record for addition to a permissioned distributed database that is distributed at least in part between the regulator system and either the operator system or the enterprise system.
