Abstract

A attach request for a device may be received. The request may include a subscriber identity for the device. The subscriber identity may be matched to a subscriber identity pattern. The subscriber identity pattern may be used to retrieve a subscriber record. Subscriber data from the subscriber record may be returned in response to the attach request.

Claims

1. A subscriber data server, comprising:

a subscriber record database to store a subscriber record comprising a primary subscriber identity, a subscriber identity pattern covering a range of subscriber identities, including a range size associated with the primary subscriber identity to encompass a range of different subscriber identities, and subscriber data including subscriber profile data, the subscriber data including various subscriber profile data stored in a Home Location Register (HLR) to enable devices to connect to cellular networks; and

control software stored on a non-transitory computer readable medium to;

receive an attach request for a device as part of a location update procedure, the request including a subscriber identity for the device, and the subscriber identity being different than the primary subscriber identity;

retrieve the subscriber record by matching the subscriber identity to the subscriber identity pattern when the subscriber identity is within the range of subscriber identities; and

return the subscriber profile data from the subscriber record, wherein the control software is to;

receive a second attach request for a second device while the first device is still attached to the network, the second request including a second subscriber identity matching the subscriber identity pattern; and

when the first device has been connected for at least a minimum period of time;

disconnect the first device and return the subscriber data from the subscriber record to allow the second device to connect.

2. The subscriber data server of claim 1, further comprising:

an authentication record database to store a single authentication record for a plurality of subscriber identities matching the subscriber identity pattern.

3. The subscriber data server of claim 1, further comprising:

an authentication record database to store a separate authentication record for separate subscriber identities matching the subscriber identity pattern.

4. The subscriber data server of claim 1, further comprising:

a log to store, for a device, connection attempt times, connect times, disconnect times, device subscriber identity, and primary subscriber identity.

5. A method, comprising:

receiving an attach request for a device as part of a location update procedure, the request including a subscriber identity for the device;

matching the subscriber identity to a subscriber identity pattern by determining when the subscriber identity is within a range of subscriber identities covered by the subscriber identity pattern;

retrieving a subscriber record using the subscriber identity pattern;

retrieving subscriber data from the subscriber record, the subscriber data including subscriber profile data and various subscriber profile data stored in a Home Location Register (HLR) to enable devices to connect to cellular networks; and

returning the subscriber data, wherein the method further includes;

receiving a second attach request for a second device while the first device is still attached to the network, the second request including a second subscriber identity for the second device matching the subscriber identity pattern; and

when the first device has been connected for at least a minimum period of time;

disconnecting the first device and returning the subscriber data from the subscriber record in a response to the second attach request to allow the second device to connect.

6. The method of claim 5, further comprising:

retrieving authentication information keyed to the primary subscriber identity or the subscriber identity pattern, the authentication information being shared between devices matching the subscriber identity pattern; and

returning the authentication information.

7. The method of claim 5, further comprising:

retrieving authentication information keyed to the subscriber identity for the device, the authentication information being unique to the device; and

returning the authentication information.

8. The method of claim 5, further comprising:

when the first device has been connected for less than the timeout period;

returning a refusal to grant the second attach request.

9. The method of claim 5, further comprising retrieving the timeout period from the subscriber record.

10. The method of claim 5, further comprising disconnecting the first device by transmitting a cancel location message to a visitor location register, mobile service center, or serving general packet radio service support node to which the first device is currently associated.

11. A non-transitory computer readable medium storing instructions to:

obtain a subscriber identity pattern corresponding to a range of subscriber identities;

obtain a primary subscriber identity corresponding to the subscriber identity pattern;

obtain subscriber data for a set of devices having subscriber identities within the range of subscriber identities matching the subscriber identity pattern, the subscriber data including subscriber profile data and various subscriber profile data stored in a Home Location Register (HLR) to enable devices to connect to cellular networks;

provision a subscriber record keyed to the primary subscriber identity and including the subscriber identity pattern and the subscriber data

receive an attach request for a requesting device having a first subscriber identity matching the subscriber identity pattern as part of a location update procedure;

determine when a currently attached device having a second subscriber identity matching the subscriber identity pattern has been attached for more than a minimum period of time;

when the currently attached device has been attached for less than the minimum period of time, deny the attach request;

when the currently attached device has been attached for at least the minimum period of time, disconnect the currently attached device, grant the attach request and return the subscriber data from the subscriber record to allow the second device to connect.

12. The non-transitory computer readable medium of claim 11, storing instructions to:

provision separate authentication records for a set of devices matching the primary subscriber identity.
