The disclosure discloses a method for Device to Device (D2D) resource pool measurement and reporting. A User Equipment (UE) measures a D2D resource pool, and sends measurement information of the D2D resource pool. The disclosure also discloses another method, Evolved Node B (eNodeB), UE and storage medium for D2D resource pool measurement and reporting.

Methods and apparatuses for event reporting are disclosed. According to an embodiment, an access and mobility management function (AMF) entity detects a status of a terminal device changing from unreachable to reachable and sends, to a first entity, a report indicating that the terminal device is reachable. The report contains a maximum availability time until which the terminal device is expected to be reachable.

Various communication systems may benefit from handling of various connection states. For example, certain wireless communication systems may benefit from a hybrid release that may enable any access management function to process a user equipment transaction. A method can include determining, by an access management function, whether to remain a serving node for a user equipment. The method can include taking an action with respect to an NG2 association for the user equipment based on the determination.

Disclosed are various embodiments that provide distributed user plane functions for radio-based networks. In one embodiment, data is received from a client device connected to a radio access network of a radio-based network. The data is forwarded to a user plane component of a user plane function. The user plane component is implemented in a computing device of the radio access network. The data is processed by the user plane component. The data that has been processed is then routed to a data network.
