Abstract: A method comprises receiving network slice information from a core network entity, the network slice information related to a network slice which is not supported in one or more cells of a first tracking area, but which is supported in one or more cells of a second tracking area. The method further comprises triggering a procedure at a user equipment to access said network slice based on said network slice information when said user equipment is in one or more cells of the first tracking area.

Abstract: Methods and apparatus, including computer program products, are provided for congestion management and service continuity. In some example embodiment, there may be provided a method comprising sending, by a user equipment, an indication of whether the user equipment supports an automatic re-mapping of a network slice to a fallback network slice; and receiving, by the user equipment, an acknowledgment from a network in response to the sent indication. Related systems, methods, and articles of manufacture are also disclosed.

Abstract: There is provided an apparatus, said apparatus comprising means for providing a first registration request from a user equipment to a first visited network for a first network slice provided by the first visited network and providing a further registration request from the user equipment to at least one second visited network for at least one second network slice provided by the second visited network, wherein the first network slice and at least one second network slice are mapped to subscribed network slices in a home network and the at least one second network slice is not provided by the first visited network.

Abstract: Methods, apparatuses, and computer program products are described that support access to multiple mutually exclusive, isolated, and/or disjointed network slices by User Equipment, UE, across one or more networks. The UE connects (1102) to multiple network slices via a Radio Access Network, RAN, by way of one or more Radio Resource Control, RRC, connections. The RRC connections are maintained (1104) between the UE and a respective network slice by switching the connection to inactive or idle when another RRC connection needs to be established. The UE and/or the RAN switches (1106) an RRC connection from an inactive state to an active state based on a trigger condition such as receipt of a notification that downlink data is available over the inactive RRC connection. A Unified Data Management Function, UDM, stores and updates registration state information for the UE and multiple Access and Mobility Management Functions, AMFs.

Abstract: There is provided an apparatus, said apparatus comprising means for at a user equipment registered with a first network and a second network, accessing the second network and receiving at the user equipment from the second network a downlink data notification associated with the first network.

Abstract: A system that automatically reduces test cycle time to save resources and developer time. The present system selects a subset of tests from a full test plan that should be selected for a particular test cycle, rather than running the entire test plan. The subset of tests is intelligently selected using metrics such as tests associated with changed code and new and modified tests.

Abstract: A system and method for dynamically adjusting the amount of memory allocated to a virtual machine includes generating, by a memory resizing system, a current memory usage profile for the virtual machine. The memory resizing system and the virtual machine are part of a virtual computing system and the current memory usage profile is generated by mapping, as a function of time, memory usage information from the virtual machine. The system and method also include computing an upper baseline based upon a peak memory usage in the current memory profile, updating an initial memory allocation of the virtual machine based upon the upper baseline and a predetermined threshold for obtaining an initial revised memory allocation, determining a moving average of memory usage from a historical memory usage profile, and updating the initial revised memory allocation based upon the moving average of memory usage for obtaining a final revised memory allocation.

Abstract: A system and method include providing backup and restore capability to a cluster node. The cluster node includes a controller virtual machine (CVM) that is communicably coupled to a plurality of cloud platforms and provides the capability of carrying out backup and restore at the cloud platforms without having to run a CVM at the cloud platform. The CVM can backup objects to the cloud platform and store metadata information related to the object in storage. The CVM also takes snapshots of the object and stores the snapshots. The CVM also determines a changed data chunks that include the changes made to the object from the last snapshot. To restore the object, the CVM restores the object based, in part, on the snapshots, the changed data chunks, and the metadata stored at the node.
