With a 3rd Generation Partnership Project (3GPP) fifth-generation (5G) network architecture comprising smaller cell sizes, the movement of a User Equipment (UE) generates frequent signaling from a control plane (CP) to a user plane (UP) to update a user’s location. As traffic increases between a CP and a UP, the number of Packet Forwarding Control Protocol (PFCP) control messages increases, requiring a network’s nodes to perform additional socket operations. Importantly, each socket input/output (I/O) operation and system call is a costly action from a resource utilization point of view. To address the type of challenge that was described above, techniques are presented herein that reduce the number of socket I/O operations and system calls to, in turn, reduce central processing unit (CPU) and I/O utilization and increase the reliability of signaling and yield better bandwidth utilization. Use of the presented techniques provides a number of benefits including, for example, reduced CPU and I/O resource utilization (resulting a in saving of resources for a gateway node, reduced latency, improved key performance indicators (KPIs) and user experience, and reduced operator capital expenditure), better network bandwidth utilization, etc.
