The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method for coordinating an unavailability period parameter of User Equipment (UE) in wireless network is provided. The method includes determining, by an Application Function (AF) of a network apparatus in the wireless network, the unavailability period parameter for the UE based on at least one event to be performed at the UE. Further, the method includes sending, by the AF of the network apparatus, the unavailability period parameter for the UE to an Access and Mobility Management Function (AMF) of the network apparatus. Further, the method includes configuring the unavailability period parameter at the UE. In an embodiment, UE detects it has to execute the event, UE initiates a non-access stratum (NAS) procedure to indicate it will become unavailable by indicating the unavailability period parameter to the 5th generation core (5GC), 5GC forwards the unavailability period parameter to the AF, with this the co-ordination between UE, 5GC and AF is achieved.

In an example, a Dynamic Host Configuration Protocol (DHCP) lease request from a client device connected to a network is received. Based on the DHCP lease request, an Internet Protocol (IP) address is assigned to the client device for a lease time. A first lease renewal request is received. A probability of utilization for a lease time block is predicted based on a historical lease pattern, device characteristics, traffic information, and DHCP information. Based on a combination of the probability of utilization and a reward value, the lease time block is allotted for lease renewal. For each allotment, the reward value is adjusted based on deployment characteristics and traffic load in the network, and a network connection duration of the client device. A normalized reward value for the lease time block is determined based on reward values for the lease time block over multiple allotments.

A User Equipment (UE) processing method and device is provided. The method includes that: a forwarding device receives an indication message for managing a UE sent by a controller; and the forwarding device manages the UE according to the received indication message.

A system includes: a server; and a terminal. The server manages a first connection state indicating a state of connection with the terminal based on whether the connection with the terminal is determined as established, and performs deallocation or reuse of a server-side resource allocated by the server, based on whether the first connection state is synchronized with a second connection state managed in the terminal. The terminal repeatedly checks a connection with the server using the connection path including the at least part in which the wireless communication is performed, and manages the second connection state indicating a state of the connection with the server, based on whether the connection with the server is determined as established. The terminal performs deallocation or reuse of a terminal-side resource allocated by the terminal, based on whether the second connection state is synchronized with the first connection state.

A method for IP [=Internet Protocol] communication between a mobile terminal and its correspondent node in a mobile radio network. The method comprises establishing an IP connection between the mobile terminal and its correspondent node. After detecting a period of inactivity in the IP connection, keep-alive messages are sent via the IP connection at predetermined intervals, which are varied. The method comprises monitoring the lengths of several periods of inactivity at which the mobile radio network disconnects the IP connection.

A method may be performed by a network entity of a wireless communication network. A first PDU session may be established for a wireless terminal (UE) using a first NodeB base station (MgNB) and a first user plane function entity (UPF1). A second PDU session may be established for the wireless terminal (UE) using a second NodeB base station (SgNB) and a second user plane function entity (UPF2). The first and second PDU sessions may be established for the wireless terminal (UE) using the first and second NodeB base stations so that the first and second PDU sessions are provided concurrently using dual connectivity DC to provide redundant data paths for communication of data for the wireless terminal (UE) through the wireless communication network.

A method for setting a value of an inactivity timer for transitioning between states of a data session in a network comprising a first entity and a second entity providing network analytics is provided. The method includes obtaining, by the second entity, input data comprising communication description information for at least one user equipment (UE), and providing, by the second entity to the first entity, output analytics generated based on the input data, the output analytics comprising UE communications analytics for each data session where the output analytics are used to determining whether to update a value of an inactivity timer for a data session.
