摘要:
A method for monitoring a status in a form of presence and/or absence of a subscribed network entity in a network by a presence service, wherein the network is a software defined network having one or more forwarding elements being configurable for recognizing and applying one or more actions on packets being forwarded by the forwarding elements and one or more network entities, includes monitoring the status of the subscribed network entity. The monitoring the status of the subscribed network entity includes providing the presence service with a status update of the selected network entity only when at least one of the one or more forwarding elements, to which the selected network entity is directly connected, has detected a change in the presence status of the subscribed network entity; and dropping packets of the subscribed network entity destined for the presence service.

A method for service management for terminals with broadband connections, wherein the terminal is connected through a home gateway to a service connected in an operator network, the home gateway being attached to an access node of the operator network, includes the steps of monitoring whether the terminal is temporarily not using the service, delegating the service and transferring its current status and/or data to the access node, and tearing down the connection between the home gateway and the access node while operating the service in the delegated service host.

A method for measuring network operation related parameters in a mobile communication network with a core network and a radio-access network, preferably in form of a LTE- or UMTS-network, includes the steps of a) configuring an entity in the mobile communication network for measuring including network operation related parameters to be measured, b) selecting a measuring entity, c) measuring the network operation related parameters by the measuring entity, and d) analyzing the measured parameters wherein a filtering is performed prior to step d), wherein the filtering is performed on an entity in the radio access network of the mobile communication network and wherein the filtering reduces the amount of data of the measured network operation related parameters for step d). A system for measuring network operation related parameters is also described.
摘要:
A method for providing a public key/secret key pair for encrypting and decrypting data, wherein the public key of the public key/secret key pair and a master secret key are generated based on predefined policy information, and wherein the secret key of the public key/secret key pair is generated based on the generated master secret key and predefined attribute information. A method for accessing a system in an untrusted environment and a system for providing a public key/secret key pair for encrypting and decrypting data as well as a use for access control are also described.
摘要:
A method for optimizing network performances, wherein the network includes one or more network nodes (1), performance parameters of the network nodes (1) being controlled by element of dedicated optimization modules (3), wherein each optimization module (3) monitors at least one performance parameter of the network node (1) to which the optimization module (3) is associated and generates a change request for the current value of the performance parameter on the basis of preset rules, is characterized in that the change requests generated by different optimization modules (3) of the network node (1) are forwarded to a shared controlling element (2), wherein the shared controlling element (2) enforces a coordination of the received change requests on the basis of a configurable algorithm. Furthermore, a corresponding system is disclosed.
摘要:
A method and system for detecting anomaly of user behavior in a network with a hierarchical topology, including a plurality of users, at least two bridges to each of which at least one user is connected to and wherein the bridges are configured to be operable to connect the corresponding users to the network, and at least one predetermined profiling network entity, the method includes the steps of: a) determining common behaviors of the users connected to the respective bridges; b) transmitting the determined common behaviors to the profiling network entity; c) determining an overall profile based on the transmitted common behaviors; d) transmitting back the determined overall profile to the bridges; and e) detecting anomaly of user behavior of the users connected to the corresponding bridges based on the overall profile.
摘要:
A method for controlling the admission of a flow to a network, particularly a WiMAX (Worldwide Interoperability for Microwave Access) network, wherein an estimation of maximum capacity required within a link of the network and/or within the network will be performed for examining, whether the flow requesting to enter the network with at least one QoS (Quality of Service) reservation of resources can be admitted, by finding first sets of intersections between all pairs of QoS reservations, i.e. the QoS reservations already accepted within the link and/or within the network and the at least one QoS reservation requested by the flow. The method is characterized by structuring the found sets of intersections by building a matrix of intersections of QoS reservations and—based on the matrix—deriving the rest of the sets of intersections between the intersections found, based on information obtained regarding the QoS reservations involved in each intersection.
摘要:
A method of supporting power control in a communication network, the network including a plurality of network elements (1) that perform packet forwarding, wherein each network element (1) includes one or more ports—element ports (2)—, is characterized in the steps of assigning a flow table (4) to each of the network elements (1), wherein the flow table (4) includes flow entries (5) that specify via which element ports (2) to forward packets the network element (1) receives, deriving target sets from the flow tables (4), wherein a target set characterizes either a network element (1) as a whole—element target set—or an individual element port (2)—port target set—in terms of its utilization, and based on changes in the respective target sets, deciding on the enforcement of power states on the network elements (1) and/or the element ports (2).
摘要:
A method and system for providing service access to a user, includes the steps of: a) Registering a local identity provider located in al local network at a global identity provider with a local identifier of the local identity provider, b) Requesting service access requiring identity authentication to a service provider by a user located in the local network, c) Requesting an identity management service from the global identity provider by the service provider, d) Redirecting the user's access request to the local identity provider according to the provided local identifier within the local network, e) Checking if the local identifier corresponds to the local network of the user, f) Providing the requested identity management service to the service provider by the global identity provider in accordance with a result of the checking according to step e), and g) Granting service access for the user to the service provider.
摘要:
For allowing an intelligent and/or resource efficient delivery of video content and/or determining of video content popularity and/or user behavior a method for determining user behavior during delivery of video content is claimed, wherein a user is requesting a delivery of a video content from a provider via a network. The method is characterized in that the provider exploits information transmitted between the user and the provider due to the execution of a trick play function by the user for scheduling the delivery and/or determining video content popularity and/or user behavior. Further, an according network is claimed, preferably for carrying out the above mentioned method.
