Abstract

To register a mobile device located in a first network with a packet-switched services network, a registration request is received from an aggregation device in the first network. The registration request contains an identifier of the aggregation device and identification information of the mobile device, where the identification information is previously unknown to the packet-switched services network. A globally unique identifier of the mobile device is dynamically created based on the identifier of the aggregation device and the identification information of the mobile device, wherein the globally unique identifier is used for uniquely identifying the mobile device in the packet-switched services network.

Claims

1. A method of registering a mobile device located in a first network with a packet-switched services network, comprising:

receiving, from an aggregation device in the first network, a registration request containing an identifier of the aggregation device and identification information of the mobile device, wherein the identification information is previously unknown to the packet-switched services network; and

dynamically creating a globally unique identifier of the mobile device based on the identifier of the aggregation device and the identification information of the mobile device, wherein the globally unique identifier is used for uniquely identifying the mobile device in the packet-switched services network.

2. The method of claim 1, further comprising sending the globally unique identifier to an application server for storage at the application server to enable the application server to route calls directed to the mobile device.

3. The method of claim 2, wherein sending the globally unique identifier to the application server comprises sending the globally unique identifier to a voice call continuity (VCC) application server.

4. The method of claim 1, further comprising receiving the identifier of the aggregation device in response to the aggregation device performing a registration procedure with the services network.

5. The method of claim 1, wherein the identification information of the mobile device includes a mobile identity number and an electronic serial number of the mobile device, wherein receiving the registration request containing the identification information comprises receiving the registration request containing a parameter that includes a concatenation of the identifier of the aggregation device, the mobile identity number, and the electronic serial number.

6. The method of claim 5, wherein the parameter is a SIP.INSTANCE parameter.

7. The method of claim 1, wherein creating the globally unique identifier comprises creating a Globally Routable User Agent Uniform Resource Identifier (GRUU).

8. The method of claim 1, wherein creating the globally unique identifier is part of a registration procedure performed in the packet-switched services network initiated by the registration request.

9. The method of claim 8, wherein performing the registration procedure in the services network comprises performing the registration procedure in a Session Initiation Protocol (IP) network.

10. The method of claim 1, wherein the receiving and creating are performed by a node in the packet-switched services network.

11. A node for use in a packet-switched services network, comprising:

an interface to receive a registration request sent by an aggregation device associated with an enterprise network to register a mobile device in the services network, wherein a unique identifier of the mobile device is previously unknown to the packet-switched services network, wherein the registration request contains an identifier of the aggregation device and identification information of the mobile device; and

a processor to dynamically create a globally unique identifier of the mobile device based on the identifier of the aggregation device and the identification information of the mobile device, wherein the globally unique identifier is used for uniquely identifying the mobile device in the packet-switched services network.

12. The node of claim 11, further comprising logic to implement tasks of a serving call session control function (S-CSCF).

13. The node of claim 11, wherein the identification information of the mobile device includes a mobile identity number and an electronic serial number of the mobile device, wherein the registration request contains a parameter that includes a concatenation of the identifier of the aggregation device, the mobile identity number, and the electronic serial number.

14. The node of claim 13, wherein the parameter is a SIP.INSTANCE parameter.

15. The node of claim 11, wherein the globally unique identifier is a Globally Routable User Agent Uniform Resource Identifier (GRUU).

16. The node of claim 11, wherein the processor is to further:

receive a request to establish a communications session with the mobile device, wherein the request contains a mobile directory number of the mobile device;

forward the request to a voice call continuity application server; and

receive a modified version of the request from the voice call continuity application server, wherein the modified version of the request contains the globally unique identifier of the mobile device.

17. The node of claim 11, wherein the processor is to further:

send a notification to a voice call continuity application server, wherein the notification contains the globally unique identifier of the mobile device.

18. An article comprising at least one computer-readable storage medium containing instructions that when executed cause a node in a packet-switched services network to:

receive, from an aggregation device in a first network, a registration request containing an identifier of the aggregation device and identification information of a mobile device attached to the first network, wherein the identification information is previously unknown to the packet-switched services network; and

dynamically create a globally unique identifier of the mobile device based on the identifier of the aggregation device and the identification information of the mobile device, wherein the globally unique identifier is used for uniquely identifying the mobile device in the packet-switched services network.

19. The article of claim 18, wherein the aggregation device is a femtocell base station.

20. The article of claim 18, wherein the globally unique identifier is a Globally Routable User Agent Uniform Resource Identifier (GRUU).

21. The article of claim 18, wherein the identification information of the mobile device includes a mobile identity number and an electronic serial number of the mobile device, and wherein the registration request contains a parameter that includes a concatenation of the identifier of the aggregation device, the mobile identity number, and the electronic serial number.
