Abstract

A method in a first user terminal (300, 500) for supporting provision of capabilities of the first user terminal to a second user terminal (302) is provided.

The method comprises receipt (402) of a capability request from the second user terminal. Upon receipt of the capability request, filtering rules are used (406) on the capabilities of the first user terminal, wherein the filtering rules have been pre-configured for the first user terminal to control exposure of said capabilities. Thereafter a capability message is transmitted (408) to the second user terminal, wherein at least one of the capabilities of the first user terminal have been omitted from the capability message based on the filtering rules.

Claims

1. A method in a first user terminal for supporting provision of capabilities of the first user terminal to a second user terminal, the method comprising:

receiving a capability request from the second user terminal,

use filtering rules on the capabilities of the first user terminal, wherein the filtering rules have been pre-configured for the first user terminal to control exposure of said capabilities, and

transmitting a capability message to the second user terminal, wherein at least one of the capabilities of the first user terminal have been omitted based on the filtering rules.

2. A method according to claim 1, wherein the capability request is a Session Initiation Protocol, SIP, Options message and/or the capability message is a SIP 200 OK message.

3. A method according to claim 1, further comprising checking if a capability privacy parameter is set, said capability privacy parameter indicating that said filtering rules shall be used on the capabilities of the first user terminal.

4. A method according to claim 3, wherein the capability privacy parameter pertain to an identity of a user of the second user terminal.

5. A method according to claim 4, wherein the capability privacy parameter pertain to an identity of users not present in a contact book of the first user terminal.

6. A method according to claim 4, wherein the capability privacy parameter pertain to an identity of one or more users present in a contact book of the first user terminal.

7. A method according to claim 1, wherein the filtering rules pertain to one or more of;

a current status or activity of the first user terminal and its user, current geographical location of the first user terminal, time or day, and type of service.

8. A method according to claim 1-7, wherein the filtering rules are configurable by any of:

a client in the first user terminal, a downloadable application, and an interactive web interface.

9. A first user terminal configured to support provision of capabilities of a first user terminal to a second user terminal, comprising:

a receiving circuit configured to receive a capability request from the second user terminal,

a logic circuit configured to use filtering rules on the capabilities of the first user terminal, wherein the filtering rules have been pre-configured for the first user terminal to control exposure of said capabilities, and

a transmitting circuit configured to transmit a capability message to the second user terminal, wherein at least one of the capabilities of the first user terminal have been omitted based on the filtering rules.

10. A user terminal according to claim 9, wherein the logic circuit is further configured to check if a capability privacy parameter is set, said capability privacy parameter indicating that said filtering rules shall be used on the capabilities of the first user terminal.

11. A user terminal according to claim 10, wherein the capability privacy parameter pertain to an identity of a user of the second user terminal.

12. A user terminal according to claim 11, wherein the capability privacy parameter pertain to an identity of users not present in a contact book of the first user terminal.

13. A user terminal according to claim 11, wherein the capability privacy parameter pertain to an identity of one or more users present in a contact book of the first user terminal.

14. A user terminal according to claim 9, wherein the filtering rules are configurable by any of:

a client in the first user terminal, a downloadable application, and an interactive web interface.

15. A user terminal according to claim 9, wherein the filtering rules pertain to one or more of;

a current status or activity of the first user terminal and its user, current geographical location of the first user terminal, time or day, and type of service.
