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.

A method includes receiving, by a mobility management entity (MME), a redirection request message from an access and mobility management function (AMF) node, where the redirection request message includes key-related information. The method also includes generating, by the MME, an encryption key and an integrity protection key based on the key-related information. The redirection request message is used to request to hand over a voice service from a packet switched (PS) domain to a circuit switched (CS) domain.

Method of dynamically assigning storage locations starts with the processor updating first user's home location data. Processor selects communication session between first user and second user and determines second user's home location data. Processor determines a session location data that indicates current storage location that stores data of communication session received from first and second client devices. Processor identifies available data storage locations based on first user and second user's home location data and determines whether to update the session location data based on an average of a distance over network fiber using the first user and second user's home locations, current storage location, and available storage locations. In response to determining to update the session location data, processor updates session location data to indicate one of the available storage locations, and causes transfer of data of communication session to one of the available storage locations. Other embodiments are described.
