Abstract: A device determines a user equipment, associated with the device, to move to a target device provided in a pool of other devices, where the user equipment has an ongoing session. The device also moves the user equipment to the target device, via a handover procedure and without interrupting the ongoing session, when the user equipment cannot be moved to the target device via direct signaling to the user equipment. The device further moves the user equipment to the target device, via direct signaling to the user equipment and without interrupting the ongoing session, when the user equipment can be moved to the target device via direct signaling to the user equipment.

Abstract: A device estimates a load on the device based on static and dynamic load information associated with the device, provides the estimated load to the other devices in a pool of devices, and estimates, based on the estimated load, a weight of the device in the pool. The device also detects a load imbalance in the pool based on the estimated weight and weights associated with the other devices in the pool, and determines, based on the estimated load, a number of subscribers to offload from the device. The device further determines, based on the estimated weight and the weights associated with the other devices, to which of the other devices to offload the determined number of subscribers, and offloads, to address the load imbalance, the determined number of subscribers to the determined other devices in the pool.

Abstract: Communication nodes, systems and methods are described which manage and process management information using dynamic semantic variable entities governed by a formal logic and upon which computations can be performed. Such semantic variable entities include, for example, management infons and or management situations which can be used, for example, to manage policy enforcement in communication networks. Action logic is amalgamated with static situation semantics to enable dynamic policy enforcement in such networks.

Abstract: The invention relates to a computer readable medium containing a management infon modeling an execution result of a management activity in a communications network. The management infon comprises a descriptor of the management activity, at least one value representing a managed object involved in the management activity and an indication of the execution result of the management activity. The invention further relates to a method for workflow management in a communications network comprising the steps of executing a management activity defined by at least one workflow, creating a management infon modeling an execution result of the management activity and managing said at least one workflow using said management infon. The invention also relates to a computer system in a communications network comprising a processor for executing a function creating a management infon modeling an execution result of a management activity.

Abstract: A method and node for supporting PDSN load optimization in a CDMA2000 network. The Packet Core Network Manager calculates network statistics and uses the resulting numbers to set the PPP inactivity timer depending on the load on the PDSN. In a preferred embodiment, the calculation gives the mean value of the durations of the PPP sessions (KPI1), and the corresponding standard deviation (KPI2). The PPP inactivity timer is then set to M*(KPI1+KPI2) during low load, to M*KPI1 during normal load, and to M*(KPI1?KPI2) during heavy load, where 0<M<=1, preferably depending on the distribution of the subscriber inter-arrival time.

Abstract: A method, network entity and test controller for establishing a Session Initiation Protocol (SIP) session between a plurality of SIP-based network entities and performing test measurements over the SIP session. The test controller instructs the network entities to establish the SIP session and specifies which test measurements are to be performed. The SIP session is established between the network entities, the test measurements are carried out, and the results are reported back to the test controller by at least one of the network entities, which may be terminals or packet data nodes such as a CDMA2000 Packet data Switched Node (PDSN) or Base Station Controller (BSC). The network entities may comprise SIP user agents and test modules in the forms of software and/or hardware.

Abstract: A method for analyzing a traffic of encrypted packet data sent over a Packet Core Network (PCN) and a traffic analysis device are provided. The method utilizes a traffic analysis device for listening to the traffic of encrypted packet data. The method further authenticates the traffic analysis device with at least one packet data node of the PCN, and sends a code from the at least one packet data node to the traffic analysis device for allowing decryption of the encrypted packet data at the traffic analysis device. The traffic analysis device analyzes the decrypted packet data. Afterwards, the method utilizes the traffic analysis device for separating instrumentation and a packet data node function for at least one packet data node.

Abstract: A method, system and Policy Decision Point (PDP) for policy-based test management wherein high-level test goals are first defined, and high-level test policies are next created based upon the test goals. The test policies are then converted into vendor and technology specific test scripts which are transmitted, along with the test policies, from a test management tool, to a PDP such as for example to a test server, to an Element Manager/Network Manager (EM/NM), or to a Network Element (NE), where they are stored. Upon detection of a given condition, the PDP-stored test policies trigger execution of one or more associated test scripts for testing a given network entity of a monitored network, and the test results are reported back to the test management tool.
