User authorization of implicit registration of multiple identities

A network device, comprising:

• a communication interface;
• and
• a processing unit configured to:
• receive, via the communication interface, a first Mobile Directory Number (MDN) associated with an individual subscriber, wherein the individual subscriber is further associated with one or more subscriber devices,
• receive, via the communication interface, an additional MDN newly assigned to the individual subscriber;
• cause a notification, requesting the individual subscriber's acceptance of the additional MDN, to be sent via the communication interface to at least one of the one or more subscriber devices;
• receive, via the communication interface from one of the one or more subscriber devices, an acceptance of the additional MDN by the individual subscriber;
• and
• link, via the communication interface, the additional MDN, the first MDN, and the one or more subscriber devices, within an Implicit Registration Set (IRS) at a Home Subscriber Server (HSS) in an Internet Protocol Multimedia Subsystem (IMS) network for routing calls to the individual subscriber's first MDN or additional MDN at the one or more subscriber devices.

A method, comprising:

• receiving, at a device from a first remote network device via a network, a notification that requests an individual subscriber's acceptance of a second MDN newly assigned to the individual subscriber, in addition to a first MDN assigned to the individual subscriber;
• receiving, by the individual subscriber at the device, an acceptance of the additional MDN;
• sending, based on the acceptance of the additional MDN, a first message from the device to a second remote network device;
• receiving, at the device from the second remote network device, a second message that includes an identification of multiple Mobile Directory Numbers (MDNs) linked to the individual subscriber associated with the device, where in the multiple MDNs include the first MDN and the second MDN;
• and
• obtaining, at the device, a MDN-specific calling 113, an address book, and a voice mailbox for each of the multiple MDNs identified in the second message.

A device, comprising:

• a user interface;
• a communication interface coupled to an external network;
• and
• a processing unit configured to execute a phone client to:
• receive, via the communication interface from a first remote network device, a notification that requests an individual subscriber's acceptance of a second Mobile Directory Number (MDN) newly assigned to the individual subscriber, in addition to a first MDN assigned to the individual subscriber,
• receive, from the individual subscriber via the user interface, an acceptance of the second MDN,
• send, based on the receipt of the subscriber acceptance of the second MDN, a first message from the phone client to a second remote network device via the communication interface,
• receive, at the phone client from the second remote network device via the communication interface, a second message that includes an identification of multiple MDNs linked to the individual subscriber associated with the device, wherein the multiple MDNs include the first MDN and the second MDN, and
• obtain a MDN-specific calling ID, an address book, and a voice mailbox for each of the multiple MDNs identified in the second message.
