Communication system and method for multi-line, multi-device service with user capability discovery
View Patent ↗Communication systems and methods suitable for use with multiple lines associated with one or more devices are disclosed. Exemplary systems and methods provide multi-line, multi-device device capability discovery that allow capability discovery of devices with shared lines.
1. A communication system comprising:
a network configured to support a multi-line, multi-device service enabling at least one of (i) a single user device to use multiple lines of the network, and (ii) multiple user devices to use one line of the network, the network comprising:
a network contact point, wherein each user device of the network is communicatively coupled to the network contact point;
a proxy service node (PSN) communicatively coupled to the network contact point; and
at least one presence application server (PAS);
wherein at least one user device of the network comprises a client configured to allow a user to select for registration one or more lines from a plurality of lines available for the multi-line, multi-device service on the network;
wherein the PSN sends a publish message for each line registered by the user, the publish message comprising communication capability information of each registered line; and
wherein the at least one PAS receives the publish message for each registered line.
2. The communication system of claim 1 , wherein the registration of a line corresponds to registration of an IMS Public User Identity (IMPU).
3. The communication system of claim 1 , wherein the at least one user device comprises a client configured to display device capability information of at least one other device, the device capability information comprising information regarding registered lines associated with the at least one other device.
4. The communication system of claim 1 , wherein the communication system further comprises an I-CSCF and an S-CSCF, wherein the I-CSCF sends the publish message for each registered line to the S-CSCF.
5. The communication system of claim 4 , wherein each line is served by a separate S-CSCF.
6. The communication system of claim 4 , wherein each line is served by a separate presence application server.
7. The communication system of claim 1 , wherein the PSN aggregates a plurality of responses from an I-CSCF into a header.
8. The communication system of claim 1 , wherein the at least one presence application server disseminates to a second user received communication capability information of each registered line.
9. The communication system of claim 1 , wherein, in response to a request from a second user, the presence application server provides communication capabilities of at least one of (i) the user's registered lines, and (ii) the user's shared lines.
10. A communication method performed with the aid of a network configured to support a multi-line, multi-device service enabling at least one of (i) a single user device to use multiple lines of the network, and (ii) multiple user devices to use one line of the network, the method comprising the steps of:
using a client associated with a first user device of the network, enabling a first user to select for registration one or more lines from a plurality of lines available for the multi-line, multi-device service on the network;
sending, by a proxy service node (PSN) of the network, a publish message for each line registered by the user, the publish message comprising communication capability information of each registered line; and
receiving and storing the communication capability information of each registered line in a presence application server.
11. The communication method of claim 10 , wherein the registration of a line corresponds to registration of an IMS Public User Identity (IMPU).
12. The communication method of claim 10 , wherein at least one line registered by the user is shared with a second device.
13. The communication method of claim 10 , wherein device capability information of the first user device is provided for display on a second user device, the device capability information comprising information regarding registered lines associated with the first user device.
14. The communication method of claim 13 , wherein:
the registration of a line corresponds to registration of an IMS Public User Identity (IMPU);
the first user device registers a plurality of lines among the lines available for the multi-line, multi-device service on the network; and
the device capability information of the first user device associated with the plurality of registered lines is provided for display on the second user device.
15. The communication method of claim 14 , wherein the proxy service node forks the publish messages corresponding to the plurality of registered lines.
16. The communication method of claim 10 , wherein the proxy service node aggregates multiple publish messages.
17. The communication method of claim 10 , wherein the proxy service node authorizes one or more lines for use on the first user device.
18. The communication method of claim 10 , further comprising a step of using a client associated with a second user device to enable a second user to select for registration one or more lines from a plurality of lines available for the multi-line, multi-device service on the network, wherein at least one line registered by the second user is a shared line also registered by the first user.
