This paper proposes a battery life time extension method using selective data reception on smartphone according to the battery states of a smartphone. In proposed method, the battery state information of a smartphone is transmitted to the corresponding application server with keep-alive signaling or initial signaling message. The SNS application server determines whether the received data transmits...
This paper proposes a battery life time extension method which maximizes the efficiency of a battery by monitoring the available capacity of smartphone battery and by controlling the time interval for the transmission signalling of SNS application. The proposed method extends the battery life time by operating on saving mode which delays the process of sending background traffic if the battery capacity...
Multicast patching is one of the techniques to reduce the burden of a video on demand (VOD) server. A novel patching mechanism by using multi-homing has placed its logical channel into another network interface of a client terminal. The performance of proposed patching mechanism is presented via numerical analysis. In summary, our proposed scheme modifies multicast patching model using extended client...
In ubiquitous network environment, mobility is supported among various networks. When a user enjoying the media streaming service changes his attachment point, the service needs to be provided continuously. We propose a mechanism to provide seamless mobility for a user using RFID tag. We build a test bed for user mobility, and confirm that the seamless service can be provided according to the user...
We propose an integrated authentication and mobility management scheme for fast handover in NGN, and verify that the proposed scheme has lower latency time than the existing one through the integration of authentication and mobility management for handover signaling.
In this paper, we propose an information sharing algorithm to support service mobility in home network for user's convenience. The proposed algorithm creates a text file with information for service request in a personal mobile terminal. The home media terminal supports the service mobility by sharing this information file and re-requesting the service, when it connects to s personal mobile terminal...
Currently, the IPTV services are provided through a device, called as set-top box which is dependent on the service providers. This becomes a huge constraint to customers who wants to enjoy their IPTV service more than two places and also becomes a huge loss to service providers who wants to encourage more utilization by their customers. The solution for this problem is providing an IPTV service portability...
In ubiquitous network environment, the home gateway in home network will be able to support seamless service mobility about multimedia service. The multimedia service process the signal, before the transporting stream. So, we propose a multimedia signaling which supports fast signaling for the mobility of multimedia service in a home network. And we measure the latency time of signaling by simple...
