Abstract: A video-communication service in a mobile communication network using a packet-switched connection, in which a monitoring of a radio channel portion is performed at the mobile stations of the users involved in the communication. Parameters of the video communication (e.g. the coding rate) are adjusted based on a result of the monitoring of the radio channel portion.

Abstract: A method for generating a network address in a communication network includes at least one user equipment and a network equipment. The method includes: a) providing a same shared secret key both at the at least one user equipment and at the network equipment; and b) generating at least a portion of the network address at the at least one user equipment and at the network equipment based upon at least the shared secret key.

Abstract: A method of operating a wireless communications network is adapted to provide services to users exploiting a first and a second different radio communications technologies, for example, an enhanced general packet radio service network. The method includes: providing, in a user profile available at the network, a subscription indication adapted to indicate that the user has subscribed for being provisioned with the network services through the first radio communication technology, upon reception by the network of a capability indication from the user adapted to indicate to the network that the user supports the first radio communications technology, looking up the user profile for the presence of the subscription indication; and in case the subscription indication is not found, handling the user as if supporting the second radio communications technology but not the first radio communications technology.

Abstract: A video-communication service in which a separation in different components of the video-communication is caused at the telephone equipment of the users, e.g., a separation in a video and in a voice component. The different components are transmitted on different connections between the telephone equipment of the users. The users have the possibility of selectively dropping any one of the different connections.

Abstract: To measure the quality of service at the application level in a telecommunication network (N), a function (A) is provided for carrying out sessions at the application level on said network (N). Through this activation function (A), sessions are then carried out, measuring (F) and also storing (HK in a set of points (S1, . . . , Sk, Sn) of the network (N) data indicative of the behavior of said network. The possible occurrence of critical situations relating to quality of service is verified (B) and, upon the occurrence of a said critical situation, a trigger signal (Trigger) is generated. By effect of the generation of said trigger signal, the data indicative of the behavior of the network measured and stored in the aforesaid set of points of the network (N) are collected in centralized fashion (H). The data thus collected are indicative of the end-to-end quality of service of the network (N) itself. Preferential application to packet networks like mobile telephony network such as GPRS or UMTS networks.
