Abstract

A method includes receiving, by an equipment identity register application in the target mobile network, an International Mobile Equipment Identity (IMEI) of a user equipment (UE) associated with the subscriber and a Subscriber Identity Module (SIM) identifier (ID) identifying an inactive SIM card inserted into the UE or an inactive electronic SIM (eSIM) profile installed at the UE, determining that the UE is attempting to attach to the target mobile network for a first time based on the IMEI and the SIM ID, adding an event to an event queue of the target mobile network, and processing the event by accessing subscriber data stored at the source mobile network to validate that the IMEI of the UE is indicated in the subscriber data stored at the source mobile network, wherein the subscriber data includes a subscriber account indicated by the IMEI of the UE.

First claim

What is claimed is:

1. A method for migrating a subscriber from a source mobile network associated with a source mobile network operator to a target mobile network associated with a target mobile network operator, wherein the method comprises:
adding, by an equipment identity register application in the target mobile network, an event to an event queue of the target mobile network, wherein the event indicates an International Mobile Equipment Identity (IMEI) of a user equipment (UE) associated with the subscriber and a Subscriber Identity Module (SIM) identifier (ID) identifying a SIM card inserted into the UE or electronic SIM (eSIM) profile installed at the UE;
processing, by a network event orchestration manager application in the target mobile network, the event by accessing subscriber data stored at the source mobile network to validate that the IMEI of the UE is indicated in the subscriber data stored at the source mobile network, wherein the subscriber data includes a subscriber account indicated by the IMEI of the UE;
when the IMEI of the UE is indicated in the subscriber data:
transmitting, to the UE using a target mobile network application program interface (API), an instruction to activate the SIM card or eSIM profile at the UE; and
transmitting, to the UE using the target mobile network API, SIM data and an instruction to the UE to program and activate the SIM card or the eSIM profile at the UE, wherein the SIM data associates the SIM card or the eSIM profile to the subscriber.

2. The method of claim 1 , further comprising:
determining, by the network event orchestration manager application, a source service for the subscriber that is to be migrated from the source mobile network operator to the target mobile network operator;
determining, by the network event orchestration manager application, a target service provided by the target mobile network operator, wherein the target service matches the source service; and
accessing, by the network event orchestration manager application, service data associated with the source service at the source mobile network to provide the target service to the UE.

3. The method of claim 2 , wherein the source service and the target service are associated with at least one of billing services, voicemail services, text messaging services, or third-party application services.

4. The method of claim 1 , further comprising sending, by the network event orchestration manager application, a companion device eSIM profile of the target mobile network and corresponding activation instructions to a companion device based on activating the SIM card or the eSIM profile at the UE.

5. The method of claim 1 , wherein the subscriber data remains stored at the source mobile network, without being stored at the target mobile network, while the UE accesses the target mobile network.

6. The method of claim 1 , further comprising:
receiving, by the target mobile network API, the subscriber data from the source mobile network; and
storing, by the network event orchestration manager application, the subscriber data in a memory of the target mobile network.

7. The method of claim 1 , wherein the SIM data includes a Mobile Subscriber Integrated Services Digital Network Number (MSISDN) identifying the subscriber.

8. The method of claim 1 , further comprising deactivating, by the network event orchestration manager application, a cellular subscription of the subscriber from the source mobile network.

9. A method for migrating a subscriber from a source mobile network associated with a source mobile network operator to a target mobile network associated with a target mobile network operator, wherein the method comprises:
adding, by an equipment identity register application in the target mobile network, an event to an event queue of the target mobile network, wherein the event indicates an International Mobile Equipment Identity (IMEI) of a user equipment (UE) associated with the subscriber and a Subscriber Identity Module (SIM) identifier (ID) identifying a SIM card inserted into the UE or electronic SIM (eSIM) profile installed at the UE;
processing, by a network event orchestration manager application in the target mobile network, the event by accessing subscriber data stored at the source mobile network to validate that the IMEI of the UE is indicated in the subscriber data stored at the source mobile network, wherein the subscriber data includes a subscriber account associated with the IMEI of the UE;
migrating, by the network event orchestration manager application, the subscriber data at the source mobile network to the target mobile network by authorizing the target mobile network to access the subscriber data stored at the source mobile network; and
transmitting, to the UE using a target mobile network application program interface (API), SIM data and an instruction to activate the SIM card or the eSIM profile, wherein the SIM data associates the SIM card or the eSIM profile to the subscriber when the IMEI of the UE is indicated in the subscriber data.

10. The method of claim 9 , further comprising:
determining, by the network event orchestration manager application, a source service for the subscriber that is to be migrated from the source mobile network operator to the target mobile network operator;
determining, by the network event orchestration manager application, a target service provided by the target mobile network operator, wherein the target service matches the source service; and
accessing, by the network event orchestration manager application, service data associated with the source service at the source mobile network to provide the target service to the UE.

11. The method of claim 10 , wherein the source service and the target service are associated with at least one of billing services, voicemail services, text messaging services, or third-party application services.

12. The method of claim 9 , further comprising sending, by the network event orchestration manager application, a companion device eSIM profile of the target mobile network and corresponding activation instructions to a companion device based on activating the SIM card or the eSIM profile at the UE.

13. The method of claim 9 , wherein the SIM data includes an MSISDN identifying the subscriber.

14. The method of claim 9 , further comprising deactivating a cellular subscription of the subscriber from the source mobile network.

15. A system comprising:
at least one processor;
at least one non-transitory memory; and
a network event orchestration manager application, stored in the at least one non-transitory memory, which when executed by the at least one processor, causes the at least one processor to be configured to:
process an event from an event queue by accessing subscriber data stored at a source mobile network to validate that an International Mobile Equipment Identity (IMEI) of a user equipment (UE) is indicated in subscriber data stored at the source mobile network, wherein the event indicates the combination of the UE with a SIM card inserted into the UE or electronic SIM (eSIM) profile installed at the UE, and wherein the subscriber data includes a subscriber account of a subscriber associated with the IMEI of the UE,
transmit, to the UE using a target application program interface (API), SIM data and an instruction to activate the SIM card or eSIM profile at the UE, wherein the SIM data associates the SIM card or the eSIM profile to the subscriber,
determine a source service for the subscriber that is to be migrated from the source mobile network to the target mobile network,
