Abstract

A method may include receiving, at an application server, a session initiation protocol (SIP) message including a public user identifier (ID) associated a user. The public user ID corresponds to a plurality of user devices. The method also includes determining an applicable order of alerting at least one of the plurality of user devices. The method further includes identifying at least one available user device associated with the user, based on a terminal identifier (ID) associated with each at least one available user device. The method also includes selecting a user device from the at least one available user device based on the applicable order of alerting. A SIP invite message, including a terminal ID for the selected user device, is generated. The method includes sending the SIP invite message to the selected user device based on the applicable order of alerting, and receiving a response to the SIP invite message.

1. A computer-implemented method comprising:

receiving, at a serving call session control function (S-CSCF) in a network and from a user device, a session initiation protocol (SIP) register message including a terminal identifier (ID) of the user device and a public user ID associated with a user of the user device;

sending, to a home subscriber server (HSS), a request for user authentication data, wherein the request includes the public user ID and the terminal ID;

authenticating the user device based on the user authentication data;

creating a registration context of the user device, wherein the registration context of the user device includes the terminal ID, the public user ID, a registration status of the user device, and an address of a proxy call session control function (P-CSCF) associated with the user device;

storing the registration context for the user device;

sending, to the HSS, a diameter server assignment request (SAR) message;

receiving, from the HSS, a diameter server assignment answer (SAA) message, wherein subsequent registrations from other user devices associated with the public user ID are to be directed to the S-CSCF;

sending a SIP 200 OK message to the user device;

storing, by the S-CSCF, the registration status of the user device based on a combination of the terminal ID and the public user ID, wherein the registration status includes an authentication scheme associated with the user device, and wherein storing the registration status includes;

storing the registration status and authentication scheme locally when the terminal ID is based on a device type of the user device, and

storing the registration status and authentication scheme at the HSS when the terminal ID is unique for the user; and

sending the SIP register message to an application server, wherein the SIP register message includes the terminal ID and the public user ID, and wherein the application server is to provide an incoming session to the user device based on the registration context of the user device.

2. The computer-implemented method of claim 1, wherein the terminal ID includes at least one of the device type of the user device or an Internet protocol address of the user device.

3. The computer-implemented method of claim 1, wherein sending the SAR message comprises:

sending an S-CSCF address to the HSS and indicating the S-CSCF as a serving node for the user associated with the public user ID.

4. The computer-implemented method of claim 1, further comprising:

storing, at the P-CSCF, contact information associated with the user device based on a combination of the terminal ID, the public user ID, and an address associated with the S-CSCF.

5. The computer-implemented method of claim 1, further comprising:

billing for a service associated with the user device based on the terminal ID.

6. The computer-implemented method of claim 1, wherein the received SIP register message further includes an international mobile subscriber identity associated with the user device.

7. The computer-implemented method of claim 1, wherein the received SIP register message includes a terminal ID header that identifies the terminal ID of the user device.

8. A device comprising:

a memory to store a plurality of instructions; and

a processor configured to execute instructions in the memory to;

receive a session initiation protocol (SIP) register message including a terminal identifier (ID) of a user device and a public user ID associated with a user of the user device;

authenticate the user device;

determine a registration context of the user device based on the terminal ID and the public user ID, wherein the registration context includes a registration status of the user device and an address of a proxy call session control function (P-CSCF) associated with the user device;

store the registration context for the user device;

send a diameter server assignment request (SAR) message;

receive a diameter server assignment answer (SAA) message, wherein subsequent registrations from other user devices associated with the public user ID are to be directed to the device;

send a SIP registration OK message to the user device;

store the registration status of the user device based on a combination of the terminal ID and the public user ID, wherein the registration status includes an authentication scheme associated with the user device, and wherein, when storing the registration status, the processor is configured to;

store the registration status and authentication scheme locally when the terminal ID is based on a device type of the user device, and

store the registration status and authentication scheme remotely when the terminal ID is unique for the user; and

send the SIP register message to an application server, wherein the SIP register message includes the terminal ID and the public user ID, and wherein the application server is to support an incoming session for the user device based on the registration context of the user device.

9. The device of claim 8, wherein the terminal ID includes at least one of the device type of the user device or an Internet protocol address of the user device.

10. The device of claim 8, wherein the processor is further configured to execute instructions in the memory to:

store, at the P-CSCF, contact information associated with the user device based on a combination of the terminal ID, the public user ID, and an address associated with the device.

11. The device of claim 8, wherein the processor is further configured to execute instructions in the memory to:

bill for a service associated with the user device based on the terminal ID.

12. The device of claim 8, wherein the received SIP register message further includes an international mobile subscriber identity associated with the user device.

13. The device of claim 8, wherein the received SIP register message includes a terminal ID header that identifies the terminal ID of the user device.

14. A non-transitory computer-readable medium including instructions, the instructions comprising:

one or more instructions that, when executed by a processor, cause the processor to;

receive a session initiation protocol (SIP) register message including a terminal identifier (ID) of a user device and a public user ID associated with a user of the user device;
