The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments disclosed herein relate to wireless communication networks, and more particularly to managing PDU sessions in wireless communication networks. The method maintains by a user equipment (UE), a count value for the maximum number of PDU sessions for a first access and a second access on a first network entity (NE). The UE sends a PDU session establishment request when a number of active PDU sessions is lower than the count value for the maximum number of PDU sessions or an established PDU session is released on one or more of the first access and the second access in which the maximum number of the PDU sessions has been reached.
