Abstract

A method including determining whether a subscriber identification profile (SIDP) is stored within a UE; sending an initial attach request along with a default network access key to a MME, upon determining that the SIDP is not stored; receiving a first authorization in response to the initial attach request, the first authorization restricts connectivity of the UE to an M2M activation system accessed by a dedicated APN associated with the default network access key; receiving, from a subscription management system, a SIDP generated by the M2M activation system; detaching from the M2M activation system and the network; sending a second attach request to the network based on the received SIDP; and receiving a second authorization to the network in response to the second attach request; the second authorization provides unrestricted APN connectivity and access to services associated with the subscriber identification profile.

First claim

What is claimed is:

1. A method, comprising:
obtaining, by a user equipment (UE) device, a first authorization from a network based on a default network access key, wherein the first authorization is obtained without providing an international mobile subscriber identity (IMSI) and allows restricted access of the UE device through a dedicated access point name (APN) determined by a mobility management entity (MME) based on the default network access key;
receiving, at the UE device, a subscriber identification profile from a subscription management system associated with the dedicated APN; and
obtaining, by the UE device, a second authorization from the network based on the received subscriber identification profile, wherein the second authorization provides unrestricted APN connectivity and access to services associated with the subscriber identification profile.

2. The method of claim 1 , wherein obtaining the first authorization comprises:
sending, from the UE device, an initial attach request along with the default network access key to the MME within the network; and
receiving, at the UE device, the first authorization in response to the initial attach request, wherein the first authorization restricts connectivity of the UE device to a machine-to-machine (M2M) activation system.

3. The method of claim 2 , wherein obtaining the second authorization comprises:
detaching the UE device from the M2M activation system and the network;
sending, from the UE device, a second attach request to the network based on the received subscriber identification profile; and
receiving, at the UE device, the second authorization to the network in response to the second attach request.

4. The method of claim 1 , further comprising:
determining, by the UE device, whether the subscriber identification profile is stored within the UE device.

5. The method of claim 4 , wherein upon determining that the subscriber identification profile is stored in the UE device, further comprising:
determining whether a predetermined command was received to reset the stored subscriber identification profile, and in response to determining the predetermined command was received:
discarding the stored subscriber identification profile from the UE device;
sending an initial attach request along with the default network access key to an MME within the network; and
performing an attach procedure upon determining that the predetermined command was not received.

6. The method of claim 5 , wherein determining whether the predetermined command was received further comprises:
identifying at least one of an activation of a switch sequence, a simultaneous activation of a combination of switches, an activation of a dedicated switch, or a switch actuation lasting a predetermined period of time.

7. The method of claim 5 , wherein determining whether the predetermined command was received further comprises:
receiving the predetermined command upon powering on the UE device.

8. The method of claim 2 , further comprising:
receiving instructions via the network for generating the default network access key, wherein the instructions generate the default network access key based on at least one of the international mobile equipment identity (IMEI) of the UE device, an individual subscriber authentication key (Ki, Kix), encryption algorithm identifier values, or integrity algorithm identifier values;
generating the default network access key by automatically activating the instructions upon an initial powering on of the UE device and determining that the subscriber identification profile is not stored in the UE device; and
saving the default network access key in the UE device.

9. The method of claim 8 , wherein the IMEI of the UE device used in generating the default network access key includes at least one of a specific mobile country code (MCC) prefix or a specific mobile network code (MNC) prefix which is anchored to the M2M activation system.

10. The method of claim 2 , further comprising:
receiving a request to provide customer consent for a service subscription associated with the subscriber identification profile generated by the M2M activation system;
prompting a user to provide customer consent after receiving the first authorization; and
sending customer consent to the network in response to the prompting.

11. A user equipment (UE) device, comprising:
a chipset configured to store a subscriber identification profile and a default network access key;
at least one memory configured to store instructions; and
at least one processor configured to execute the instructions to:
obtain a first authorization from a network based on the default network access key, wherein the first authorization is obtained without providing an international mobile subscriber identity (IMSI) and allows restricted access of the UE device through a dedicated access point name (APN) determined by a mobility management entity (MME) based on the default network access key;
receive a subscriber identification profile from a subscription management system associated with the dedicated APN; and
obtain a second authorization from the network based on the received subscriber identification profile, wherein the second authorization provides unrestricted APN connectivity and access to services associated with the subscriber identification profile.

12. The UE device of claim 11 , wherein the instructions that obtain the first authorization further cause the at least one processor to:
send an initial attach request along with the default network access key to the MME within the network; and
receive the first authorization in response to the initial attach request, wherein the first authorization restricts connectivity of the UE device to a machine-to-machine (M2M) activation system.

13. The UE device of claim 12 , wherein the instructions to obtain the second authorization further causes the at least one processor to:
detach the UE device from the M2M activation system and the network;
send a second attach request to the network based on the received subscriber identification profile; and
receive the second authorization to the network in response to the second attach request.

14. The UE device of claim 11 , wherein the instructions further cause the at least one processor to:
determine whether the subscriber identification profile is stored within the UE device.

15. The UE device of claim 14 , wherein in response to the processor determining that the subscriber identification profile is stored in the UE device, the instructions further cause the at least one processor to:
determine whether a predetermined command was received to reset the stored subscriber identification profile, and in response to determining the predetermined command was received:
discard the stored subscriber identification profile from the UE device; and
send the initial attach request along with the default network access key to the MME within the network; and
perform an attach procedure upon determining that the predetermined command was not received.

16. The UE device of claim 15 , wherein the instructions to determine whether the predetermined command was received further cause the at least one processor to:
identify at least one of an activation of a switch sequence, a simultaneous activation of a combination of switches, an activation of a dedicated switch, or a switch actuation lasting a predetermined period of time.

17. The UE device of claim 15 , wherein the instructions to determine whether the predetermined command was r
