Method for discovering capabilities of offline users

摘要

The invention refers to a method for discovering capabilities of a first device (10) operable to communicate with a second device (20) using a telecommunications network, the first and second devices being registered at a service platform of this network, the first device being capable of accessing the service platform through a first core network (100) and the second device being capable of accessing the service platform through a second core network (200), the method comprises the steps of:
- receiving at the first core network (100) a request from the second device (20) for discovering capabilities of the first device (10);
- determining by the first core network (100) a first status indicator of the first device (10);
the method is characterised by further comprising:
- routing the request from the second device to an application server (300) of the service platform;
- identifying the first status indicator of the first device by the application server (300) and determining a second status indicator of the first device;
- sending a response from the application server to the second device (20), the response containing a set of feature tags which describe a set of services supported by the first device.
