To provide cellular communications for a large number of Internet of Things (IoT) devices, the mobile core system, called evolved packet core (EPC) in the case of a 4G system, requires a large amount of computational resources. This is because the EPC needs to maintain communication state information for IoT devices, even if they rarely send data. This paper proposes a method for reducing state information...
To provide cellular communications for a large number of internet of things (IoT) devices, the mobile core system, called as evolved packet core (EPC) in the 4G system case, emerges to equip a large amount of computational resources. This is because the EPC needs to maintain state information on the communications of the IoT devices, even if they rarely send data. This paper proposes a method for...
In this study, we propose a method for improving the scalability of sharing the flow rules, which are used to inspect and direct packets, between gateway functions in a mobile network virtualization infrastructure. The proposed method enhances the centralized management mechanism, where a controller reactively installs rules based on receiving the first packet of each flow, to reduce the load in the...
This paper proposes a service-specific network virtualization to address the tremendous increase in the signaling processing load in the evolved packet core and IP multimedia subsystem of a fifth-generation mobile communication system. The proposal creates several virtual networks that are composed of functions specialized for particular services on a mobile communication network and efficiently forwards...
A large number of attractive services, which combine the functionality of mobile terminals with existing services on the Internet, are spreading. The service delivery platform (SDP) can provide more attractive services by collaborating with telecommunication carrier services. SDP-based services are provided through collaboration among reusable service components, referred to as "enablers"...
Mobile users' demand for using the best available network connection encourages mobile network operators (MNOs) to construct multi-access networks managed by all-IP based mobile networks. For such an MNO, the IP Multimedia Subsystem (IMS) is a promising service control infrastructure to provide IP-based multimedia services with QoS guarantee in the multi-access network. The service centralization...
