摘要： A method for monitoring packets in a communication network includes at an ingress point, classifying at least one packet of a traffic received at the ingress point for determining whether packets of the traffic are to be monitored and, in the affirmative, associating them with a service of monitoring; at the ingress point, creating a selection policy to identify a packet flow of the packets to be monitored according to the service of monitoring. The method also includes installing the selection policy at one or more measuring points within the communication network, and at each measuring point, identifying the packet flow on the basis of the selection policy. The method further includes at each measuring point, applying monitoring actions associated with the service of monitoring to the identified packet flow.

摘要： A method for providing one-way delay measurements on a bidirectional packet flow exchanged between two nodes of a packet-switched network. Each packet of the bidirectional packet flow comprises a marking field. At predefined times, the two nodes start transmission of respective measurement packet blocks made of packets with marking field set equal to a measurement value. Each node continues transmission of the respective measurement packet block, until it starts receiving the measurement packet block transmitted by the other node. In response thereto, each node ends transmission of the respective measurement packet block. A measurement point placed on the path of the bidirectional packet flow detects the measurement packet blocks and provides one-way delay measurements based on their time properties. For example, the end-to-end one-way delay in a given direction may be measured as the duration of the measurement packet block transmitted in the opposite direction.

摘要： A method for delivering to a user a dedicated service restricted to a predefined service area includes, performing an access request to a dedicated service. The dedicated service is delivered from a server through a data network between a user device and the server. The method also includes determining a service profile associated with the user, and assigning to the user device a dedicated communication channel for the dedicated service. The method further includes starting a communication session with the server through the data network according to the assigned dedicated communication channel, and performing an authentication request to the server. If the service authenticates the user successfully, the position of the user is obtained, and the dedicated service is delivered to the user device.

摘要： A method for determining a Quality of Experience associated with a real-time communication session between user devices includes monitoring the real-time communication session and determining at least one quality indicator of the Quality of Experience, at least one first performance indicator of a Quality of Service, and at least one second performance indicator of the Quality of Service. Based on the quality indicator and the first performance indicator, the method determines, among a family of correlation functions indicative of the correlation between the Quality of Experience and a Quality of Service in respect of a generic real-time communication session, a correlation function which is indicative of the correlation between the Quality of Experience and the Quality of Service in respect of the monitored real-time communication session. Then the method applies the first performance indicator and the second performance indicator to the correlation function to determine said Quality of Experience.

摘要： A method for delivering to a user, through a mobile communication network, a dedicated service restricted to an access-controlled service area includes, upon detection of an access of the user into the access-controlled service area by an access control system, controlling accesses of users to the access-controlled service area, identifying a connectable device associated with the user. The connectable device is connected to the mobile communication network. Then a position of the connectable device is determined. If, based on the position of the connectable device, the connectable device is within the access-controlled service area, the dedicated service is delivered to the user by, providing, through the mobile communication network, one or more digital contents to the connectable device.

摘要： A method for a wireless network, including a node and a first device covered by the node, the node acting as serving node for the first device, and the first device transmitting first data to the node over a first link, includes determining presence of a second device covered by the node, the second device transmitting second data to a serving node over a second link, determining radio quality of the first link, determining radio quality of the second link, and determining radio quality of a third link between the second device and the first device. If the radio quality of the third link is higher than the radio quality of the second link, the second device transmits the second data to the first device over the third link and the first device retransmits, over the first link, the second data to the node.

摘要： It is disclosed a method for enabling a performance measurement in a packet-switched communication network. A first node and a second node exchange packets comprising a marking value, which they alternately switch between two alternative marking values. The second node in particular switches the marking value applicable to the packets addressed to the other node depending on the marking value comprised in packets received therefrom. The first node writes a sampling value in one packet addressed to the second node for each marking period. Upon reception of each packet comprising the sampling value, the second node copies the sampling value in a packet addressed to the first node. One or more measurement points may be provided between the two nodes, which provide performance parameters for the packets comprising the sampling value in both directions. Such performance parameters may be used for providing round trip time measurements.
