Abstract: A method for subscribing a first communicating entity to a second communicating entity. The method is implemented by the first entity and includes: requesting subscription to the second entity in order to obtain information regarding at least one event monitored by the second entity, this subscription request indicating at least one encoding format supported by the first entity; and following detection by the second entity of a the event corresponding to the subscription request, receiving, from the second entity, a notification comprising information relating to the detected event and encoded by way of a the encoding format supported by the first entity and indicated in the subscription request.

Abstract: A method for the management, by a network control entity, of a plurality of application entities offering services in the network. The management method includes: receiving, from a first entity, a bootstrapping request aimed at discovering services offered by the control entity and/or resources managed thereby; and sending a response to the bootstrapping request from the first entity, the response furthermore including at least one encoding format supported by the control entity.

Abstract: An entity for implementing a service in a network, an application device, and a method for executing an operation of a service are described. An entity is configured to implement a first service implemented by a first application device of a communications network, the entity including a management module configured to acquire, via an application programming interface of a second service implemented in the network, data managed by the second service, said management module being configured to store said acquired data in a primary cache of the entity, an update module configured to update, following a modification of one of said data managed by said second service, the primary cache to reflect said modification using said programming interface, and a processing module, configured to use at least one of said data from the primary cache when executing at least one operation of the first service.
