Abstract: A communication terminal (10) according to the present disclosure includes: a control unit (12) configured to, in a case of a movement from a communication area formed by the 5GS to a communication area formed by the EPS or a movement from a communication area formed by the EPS to a communication area formed by the 5GS, determine whether or not a communication system forming a communication area at a movement destination can satisfy requirements of services; and a communication unit (11) configured to, when it is determined that the communication system forming the communication area at the movement destination can satisfy the requirements of the services, send a connection request message to the communication system forming the communication area at the movement destination.

Abstract: A communication terminal capable of preventing a reduction in security level that is caused at the time of establishing multiple connections via 3GPP Access and Non-3GPP Access. A communication terminal according to the present disclosure includes: a communication unit configured to communicate with gateway devices disposed in a preceding stage of a core network device via an Untrusted Non-3GPP Access; and a key derivation unit configured to derive a second security key used for security processing of a message transmitted using a defined protocol with the gateway device, from a first security key used for security processing of a message transmitted using a defined protocol with the core network device.

Abstract: A centralized service communicatively links an application provider to a plurality of different message forwarding services. The centralized service receives a request and authenticates the application provider associated with the request. Further, the centralized service delivers a message embodied by the request to a first message forwarding service with a first protocol and/or to a second message forwarding service with a second protocol different than the first protocol.

Abstract: Described are systems and methods for instrumenting configuration and system settings based on targeting configuration settings at dynamically populated groups, groups with varied membership, and objects defined in a class. The systems and methods provide for attributing a configuration setting or policy to one or more objects and then targeting the object at one or more scopes.

Abstract: One exemplary embodiment uses templates that define certain features of a given service type, wherein the features are common to all services of that service type. The template can be configured by a user to obtain a service definition for the given service. The service definition is passed to a programmability layer and provides enough information that the programmability layer can construct the various monitors, rules, classes and tasks required to monitor the given service without further customization by the user. In one embodiment, the user can also customize the service definition, a desired, in order to obtain additional monitoring.

Abstract: Model-based system monitoring includes accessing a model of a system that includes multiple components and executing a monitoring policy to monitor performance of the system. A notification of a problem is received from a first component. A determination is made regarding the cause of the problem. The determination is made, at least in part, based on the model of the system. At least one component associated with the cause of the problem is then identified.

Abstract: Model-based system monitoring includes identifying multiple monitors configured to monitor multiple components in a system, and accessing multiple health models associated with the multiple monitors. A monitoring policy is generated to monitor the system. The monitoring policy is derived, at least in part, from the multiple health models.

Abstract: Model-based system monitoring includes accessing a model of a system that includes multiple components and identifying relationships among the multiple components based on the model of the system. A proposed change to at least one of the multiple components is identified. A determination is made regarding an expected impact on the system caused by the proposed change. This determination is made, at least in part, based on the model of the system.

Abstract: In accordance with certain aspects of the model-based policy application, each of a plurality of policies is associated with appropriate parts of a model of a heterogeneous system. A deployment agent is invoked to apply each of the plurality of policies to components associated with the parts of the model. An identification of a change to one of the plurality of policies is received, and the deployment agent is also invoked to apply the changed policy to selected ones of the components associated with the parts of the model.

Abstract: Model-based propagation of attributes allows a user to define one or more attributes, policies associated with the system and particular components, constraints associated with various components, and dependencies between components of the system. The user also defines the manner in which the attributes are to be propagated throughout a model of the system. The attributes are then propagated to the appropriate components in the model using information associated with the model of the system.

Abstract: Model-based configuration management and modeling identifies violations of configuration constraints. A system includes multiple components and multiple applications defined by a model of the system. A process identifies configuration settings associated with the components and configuration settings associated with the applications. A configuration policy is created for the system based on information contained in the model of the system and the configuration settings.
