A method for providing a context-based service in a communication network includes: at a context server cooperating with the network, receiving a query generated from a service application, indicating that the service application needs to receive from the context server a set of context information when a query condition is fulfilled; at the context server, generating an update rule indicating that a terminal has to transmit the context information to the context server when an update condition is fulfilled; transmitting the update rule from the context server to the terminal; detecting the context information and transmitting them to the terminal; at the terminal, receiving the context information and transmitting them to the context server when the update condition is fulfilled; and at the context server, forwarding the context information to the service application, thus allowing the service application to implement the context-based service.
