Abstract: A wireless device, a network node, a core node and methods therein, for managing reachability of the wireless device. The wireless device starts an AS (Access Stratum) reachable timer when entering an inactive state. If the AS reachable timer expires while still in the inactive state, the wireless device sends to the network node a reachable notification indicating that the wireless device is reachable.

Abstract: In exemplary embodiments of the present invention, a router determines whether or not to establish a stateful routing session based on the suitability of one or more candidate return path interfaces. This determination is typically made at the time a first packet for a new session arrives at the router on a given ingress interface. In some cases, the router may be configured to require that the ingress interface be used for the return path of the session, in which case the router may evaluate whether the ingress interface is suitable for the return path and may drop the session if the ingress interface is deemed by the router to be unsuitable for the return path. In other cases, the router may be configured to not require that the ingress interface be used for the return path, in which case the router may evaluate whether at least one interface is suitable for the return path and drop the session if no interface is deemed by the router to be suitable for the return path.

Abstract: Computational methods and systems that troubleshoot and localize failures in data storage of a multitenant application are executed in a multitenant database management system that comprises a control plane of control plane nodes and a data plane of independent and isolated data plane nodes. Each control plane node receives data requests and data queries. Each data plane node maintains data storage for tenants of the multitenant application and executes data storage and data query operations requested by the control plane nodes.

Abstract: For managing a traffic overload in a software defined network having an SDN controller, when an indication of a traffic overload is received, there are steps of identifying traffic flows which contribute to this, identifying nodes of the network controllable by the SDN controller and located along a path of the identified traffic flows before the location of the traffic overload. The SDN controller is used to control the identified nodes to control the identified traffic flows to reduce the traffic overload. By using the SDN controller to control the reduction compared to diverting suspicious traffic flows to a separate external security server, the extra network resources used for carrying the diverted traffic flows are not needed, the separate security server is not needed, and the risk of such diverted traffic flows themselves causing overloads is reduced. It can be applicable to a range of causes of overload, including denial of service attacks.

Abstract: Embodiments of the present disclosure disclose a method for determining a frequency resource, and an apparatus. The method includes: first determining, by user equipment (UE), a power headroom report; and subsequently sending, by the UE, the power headroom report (PHR) to a base station in a random access process, where the power headroom report may be carried by a related information segment of message 3 (Message 3) sent by the UE to the base station. According to the solutions provided in the present disclosure, a base station can obtain, in a timely manner, a basis for performing scheduling configuration when UE performs current uplink data transmission, and can more accurately configure power control and scheduling information for the UE. This avoids allocating the UE a channel that exceeds an uplink transmission capability of the UE, and thereby avoids an uplink bandwidth waste.
