Method for announcing services in a communication network

A method implemented by a communication device of a communication system, said communication device being connected via a communication network to other communication devices of said communication system,

• wherein the communication device, on detection of a change in availability of at least one of its hardware resources, implements an announcement phase comprising the following steps:
• obtaining a list of possible local services corresponding to actions that said communication device is able to implement relying on its hardware resources;
• obtaining a list of hardware resources of said communication device that are necessary for offering said local services;
• obtaining a list of local services available among the possible local services, according to the hardware resources necessary for offering said local services and according to the actual availability of its hardware resources;
• and
• announcing, via the communication network, the list of available local services obtained, in order to enable at least one managing device to present services globally available in the communication system via lists of available local services announced by the communication devices of said communication system.

A communication device configured to be used in a communication system, said communication device being intended to be connected via a communication network to other communication devices in said communication system:

• Wherein the communication device comprises means for implementing an announcement phase, on detection of a change in availability of at least one of its hardware resources, using
• means for obtaining a list of possible local services corresponding to actions that said communication device is able to implement by relying on its hardware resources;
• means for obtaining a list of hardware resources of said communication device that are necessary for offering said local services;
• means for obtaining a list of local services available among the possible local services, according to the hardware resources necessary for offering said local services and according to the actual availability of its hardware resources;
• and
• means for announcing, via the communication network, the list of available local services obtained, in order to enable the at least one managing device to present services globally available in the communication system by means of lists of available local services announced by the communication devices of said communication system.
