Abstract: Apparatuses and methods in a communication system for identifying transient blockage are presented. Transmission to one or more RAN nodes of parameters for the one or more RAN node is controlled to detect occurrences of sharp channel degradation events in connections served by the node. Data is received from the one or more RAN nodes, the data being related to channel or transmission events related to detected sharp channel degradation in connections served by the node. Based on the received data, likelihood is determined that one or more RAN nodes have a high level of transient blockages.

Abstract: Method, apparatuses, and computer program product for network slice minimum and maximum resource quotas with soft limits. One method may include sending by a user, a request for user connection to a network element, the request resulting in resource quota reservation in a specific network concept. The method may also include receiving from the network element, an indication of whether the request was successful or unsuccessful. The request may include at least one procedure or action indicating network resource availability. The method may further include receiving allocated resources according to resource allocation rules specific to whether the user is entitled to use the allocated resources, and whether a user connection, a session, a bearer, a signaling connection or a data radio bearer request was successful.

Abstract: Certain example embodiments provide systems, methods, apparatuses, and computer program products for emergency operations (e.g., Internet protocol multimedia subsystem (IMS) emergency calls) network slice exchange between entities in mobile networks. For example, a network node (e.g., a core network node, such as an access and mobility management function (AMF)) may provide, to a radio access network (RAN) node, information that identifies network slice(s) to be used for emergency operation(s).

Abstract: A first radio access network (RAN) accesses information indicating an availability status of an interface between an access and mobility management function (AMF) in a first wireless communication system and a mobility management entity (MME) in a second wireless communication system. The first RAN receives a trigger for a handover of a user equipment between the first RAN and a second RAN. The handover is selectively performed via the interface or a redirect via a network element shared by the first and second wireless communication systems based on the availability status. In some cases, the first RAN receive the information indicating the availability status prior to providing the request for the handover and stores the information in a database associated with the first RAN, which access the information from the database.

Abstract: A method includes receiving, from a radio access network (RAN) node within a wireless network, connection event information for one or more user devices and associated channel condition information; and determining a connection behavior status of a user device based on at least a portion of the connection event information and associated channel condition information and a connection behavior status model, wherein the connection behavior status model provides a mapping or association between connection event information and associated channel condition information for one or more user devices and a connection behavior status.
