A mobile content delivery system that optimizes the delivery of especially bandwidth-consuming content (or the flow of any peak-hour data traffic) in a way that best utilizes the free capacity in the radio network, thus enabling considerably more efficient usage of the radio capacity. It also allows new services and pricing structures to be used in the cellular network, that otherwise would not be possible. The class of delivery of message content can be selected by the user on a transaction basis, or subscription-based and pre-defined in a user profile. By choosing a scheduled delivery the user can receive the content at a fraction of the price compared to instant delivery, since the content is sent at a time when the network is least utilized.

A method of facilitating the lawful interception of an IP session between two or more terminals 12,13, wherein session uses encryption to secure traffic. The method includes storing a key allocated to at least one of terminals 12,13 or to at least one of the subscribers using one of the terminals 12,13, at the terminal 12,13 and at a node 5,8 within a network 1,6 through which session is conducted, or a node coupled to that network. Prior to the creation of session, a seed value is exchanged between the terminal 12,13 at which the key is stored and node 5,8. The key and the seed value are used at both the terminal 12,13 and the node 5,8 to generate a pre-master key. The pre-master key becomes known to each of the terminals 12,13 involved in the IP session and to the network node 5,8. The pre-master key is used, directly or indirectly, to encrypt and decrypt traffic associated with IP session.

What is proposed is a method of implementing a security system (Packet Sentry) addressing the internal security problem of enterprises having a generalized approach for inferential determination and enforcement of network policy with directory service based group correlation with transparent authentication of the connected customer and the policy enforcement inside the network. The security system enables the network to analyze and enforce policy using any bit or bits in a stream or a packet, conduct Flow Vector analysis on the data traffic, provide Application Monitoring, Normalization and user authentication validation. The system enables the network to implement Group relationship Analysis and correlation using combination of Network inferences and Directory service data resulting in generation of Group norms using statistically significant relationships. These will provide a more secure enterprise environment where data security levels can be enforced and the usage monitored effectively in the infrastructure.

Devices, networks and methods relating to routing gateway traffic in a mesh network for wireless access. A mesh network has multiple nodes in at least one gateway node through which all incoming and outgoing data traffic pass through. The nodes provide wireless access to wireless and user devices, each of which is associated with a node in the mesh network. Each gateway node contains a record detailing which nodes are providing wireless access to which wireless end user device and which nodes are associated with which end user devices. This record of each end user device's location is periodically updated as the gateway node periodically receives data from the nodes which detail the device is being serviced by which node. Any incoming data traffic destined for an end user device is encapsulated and routed to the proper node servicing that end user device.

Methods and systems are provided for evaluating atypical user data access activities within the scope of an automatically generated file security policy in organizations with multiple diverse access control models and multiple diverse file server protocols. The system monitors access to storage elements within the network. The recorded data traffic is analyzed to assess simultaneous data access groupings and user groupings, which reflect the actual organizational structure. The learned structure is then transformed into a dynamic file security policy, which is constantly adapted to organizational changes over time. The system provides a decision assistance interface for tracking abnormal user behavior.

A method and system for monitoring traffic flow includes assigning a subset of sampling points to a node or unique pair of nodes. The sampling points are determined to be the most likely to monitor data traffic, and preferably all data traffic, associated with the node or node pair. The sampling point subset may automatically be determined and assigned to the node or node pair, based, for example, on historical traffic within the network. The method further includes collecting diagnostic network traffic data from the sampling points, and obtaining sampled traffic flow counts for a flow associated with a node pair from the diagnostic traffic data collected from the sampling points assigned to the source and destination nodes of the node pair. The method further includes performing a function on the sampled traffic flow counts to obtain an estimated traffic flow count for the respective flow.
