Bring your own network — A network management technique to mitigate the impact of signaling traffic on network resource utilization

Abstract

This paper proposes the concept of Bring Your Own Network (BYON), which could be a solution to reduce the impact of signaling traffic on the efficiency of mobile network resource utilization. The BYON would be enabled by dynamically migrating and localizing related service resources as well as configuring a service-specific wired and wireless network in a coordinated manner considering the distribution shape of the devices using the specific-service as well as their mobility tendency. The signaling traffic overhead is formulated, and how the introduction of the BYON could reduce the overhead is discussed. It is shown that a modified mobile network based on the BYON, in which the functions of P-CSCF and S/I-CSCF for IP Multimedia Subsystem (IMS) are migrated onto the location of PGW in Evolved Packet Core (EPC), could reduce the signaling traffic overhead by around 30 %. This paper also details the plan to deploy a large-scale experimental wireless network environment to demonstrate the concept of BYON, i.e., virtual wireless network facility.
