Abstract: An intermediate component is intermediate between mobile terminals requesting a service, such as a push service, and a service-providing server, such as an HTTP server. The intermediate component is a connection machine or hub that is able to open a session the first time it receives a request from a mobile terminal, by instantiating a communication channel for performing the communications with the mobile terminal and storing the data regarding the open session in a connection table. Then, the connection hub generates a request to a service-providing server, including connection data, and manages the communication with the service-providing server. The connection data are inserted in every communication between the connection hub and the mobile terminal and between the connection hub and the service-providing server. From that moment on, all the data (messages, requests) exchanged between the terminal and the service-providing server are routed on the instantiated channel, thus in a fast and efficient way.

Abstract: Multimedia service contents are provided to user terminals in a wireless communication network, such as, a GPRS or UMTS network, by generating delivery packets that convey both the multimedia service contents and a corresponding service logic. These delivery packets are received and interpreted by means of an interpreter at the user terminals (client) to obtain presentation of the multimedia service contents and the interaction level between client and server according to the corresponding service logic. The multimedia contents can thus be presented interactively at the terminal while new services can be designed on the server side and made available to the user terminals without modifications being required on the terminal side.
