Abstract

Method and system for identifying contacts of a user of a device, wherein the user is a registered user of an application which is implemented at the device. Contact identifiers are retrieved from a contact list stored at the device, wherein the contact identifiers identify contacts of the user of the device. The retrieved contact identifiers are transmitted to a server associated with the application. The server determines which of the contacts identified by the transmitted contact identifiers are registered users of the application. Indications of the contacts of the user of the device which are determined by the server to be registered users of the application are transmitted from the server to the device.

Claims

1. A method of identifying contacts of a user of a device, the user being a registered user of an application which is implemented at the device, the method comprising:

retrieving contact identifiers from a contact list stored at the device, said contact identifiers identifying contacts of the user of the device;

transmitting the retrieved contact identifiers to a server associated with the application;

determining, at the server, which of the contacts identified by the transmitted contact identifiers are registered users of the application; and

transmitting, from the server to the device, indications of the contacts of the user of the device which are determined by the server to be registered users of the application.

2. The method of claim 1 wherein the step of determining which of the contacts identified by the transmitted contact identifiers are registered users of the application comprises comparing the transmitted contact identifiers with a list of registered users of the application.

3. The method of claim 1 further comprising:

determining, at the server, presence information relating to the contacts of the user of the device which are also registered users of the application; and

transmitting the determined presence information from the server to the device.

4. The method of claim 1 further comprising:

determining, at the server, device capabilities relating to respective devices of the contacts of the user of the device which are also registered users of the application; and

transmitting the determined device capabilities from the server to the device.

5. The method of claim 1 further comprising displaying, at the device, a list of the contacts of the user of the device which are determined by the server to be registered users of the application.

6. The method according to claim 5 further comprising:

receiving at the device, from the user of the device, a selection of one of the contacts from the displayed list; and

using the application to establish a call with the selected contact.

7. The method of claim 6 wherein the call is established in dependence upon presence information or device capabilities transmitted from the server to the device.

8. The method according to claim 1 wherein the server maintains a first contact list comprising contact identifiers identifying contacts of the user of the device.

9. The method according to claim 8 further comprising determining whether the contact identifiers transmitted from the device to the server differ from the contact identifiers stored in the first contact list, and if the contact identifiers transmitted from the device to the server do differ from the contact identifiers stored in the first contact list updating the first contact list in accordance with the transmitted contact identifiers.

10. The method according to claim 8 wherein the server maintains a second contact list comprising contact identifiers which are present in the first contact list and which identify registered users of the application.

11. The method of claim 10 wherein the step of determining which of the contacts identified by the transmitted contact identifiers are registered users of the application comprises retrieving the second contact list.

12. The method of claim 1 further comprising transmitting a request from the application implemented at the device to the server, wherein the step of determining which of the contacts identified by the transmitted contact identifiers are registered users of the application is performed responsive to receiving the request at the server.

13. The method of claim 11 further comprising transmitting a request from the application implemented at the device to the server, wherein the step of determining which of the contacts identified by the transmitted contact identifiers are registered users of the application is performed responsive to receiving the request at the server and further comprising updating the second contact list, responsive to receiving the request at the server, if the first contact list has been changed since the second contact list was last updated or if a list of registered users of the application has been changed since the second contact list was last updated.

14. The method of claim 1 wherein the step of transmitting the retrieved contact identifiers to the server is performed repeatedly while the application is implemented at the device.

15. The method of claim 1 wherein the indications transmitted from the server to the device are identifiers associated with the application.

16. The method of claim 1 wherein the contact identifiers retrieved from the contact list stored at the device comprise at least one of:

(i) a landline telephone number, (ii) a mobile telephone number, and (iii) an email address.

17. A system comprising a device and a server associated with an application which is implemented at the device, the system being for identifying contacts of a user of the device, the user being a registered user of the application, wherein the device is configured to:

retrieve contact identifiers from a contact list stored at the device, said contact identifiers identifying contacts of the user of the device; and

transmit the retrieved contact identifiers to the server; and

wherein the server is configured to;

determine which of the contacts identified by the transmitted contact identifiers are registered users of the application; and

transmit, to the device, indications of the contacts of the user of the device which are determined by the server to be registered users of the application.

18. A method of identifying contacts of a user of a device, the user being a registered user of an application which is implemented at the device, the method comprising:

receiving, at a server associated with the application, contact identifiers which have been retrieved from a contact list stored at the device, said contact identifiers identifying contacts of the user of the device;

determining, at the server, which of the contacts identified by the transmitted contact identifiers are registered users of the application; and

transmitting, from the server to the device, indications of the contacts of the user of the device which are determined by the server to be registered users of the application.

19. A server for identifying contacts of a user of a device, the user being a registered user of an application which is implemented at the device wherein the server is associated with the application, the server being configured to:

receive contact identifiers which have been retrieved from a contact list stored at the device, said contact identifiers identifying contacts of the user of the device;

determine which of the contacts identified by the transmitted contact identifiers are registered users of the application; and

transmit, to the device, indications of the contacts of the user of the device which are determined by the server to be registered users of the application.

20. A computer program product for identifying contacts of a user of a device, the user being a registered user of an application which is implemented at the device, and the computer program product being embodied on a non-transitory computer-readable medium and configured so as when executed on a processor of a server associated with the application to perform the steps of:

receiving contact identifiers which have been retrieved from a contact list stored at the device, said contact identifiers identifying contacts of the user of the device;

determining which of the contacts identified by the transmitted contact identifiers are registered users of the application; and

transmitting, to the device, indications of the contacts of the user of the device which are determined by the server to be registered users of the application.
