It requires that user have to verify and conform with user authentication Protocol on non-meet face to face internet services offered by mobile terminal which user make known user's own intention, and user be using the normal. It is more operation time authentication protocol than Access control Protocol. That is what need to be user authentication protocol have verified security. non-reputation, and improved high-performance in operation time for mobile terminal. In order to solve the above demand, in this paper, we would design for mobile terminal of TCP User Authentication ECC Algorithm Protocol with a performance test. Algorithm has 160 bit key and designed IPv4 & IPv6 frame architecture. We should conclude that the proposed protocol have more verified security, non-reputation, confidentiality, and improved high-performance in operation time of mobile terminal from 1 to 17 times than before.

Due to the explosive popularization of the Internet, it has been researched for many mobile terminals how to receive various multimedia information. Especially, it has been considered that a mobile terminal is serviced with multimedia information through a inherent IP address. In this paper we have proposed the Handover Signaling Method and analyzed the Handover delay time of this proposed method in wireless section. This proposed method is appropriate to Broadband systems with Mobile IP. We have simulated Handover delay time with respect to the distance between a terminal and base stations

The mobile terminal system plays a key role in medical industries which require in fast and accurate diagnosis from heterogeneous acquisition equipment. The demand for PACS (picture archiving and communication systems) has continued to increase in major hospitals and private clinics. Patient care depends on how fast the medical imaging system provides images and how accurately the images are interpreted by physicians. In this paper, we propose an efficient method to decipher the hundreds of images required by physicians to accurately diagnose patients. By exploring Motion- JPEG (M-JPEG), this paper has demonstrates the possibilities for efficient management of medical images with a newly designed image file format and improvement in imaging diagnoses through the replaying of moving pictures of a patient in a mobile environment.

Purpose: The aim of this study was to examine the effect of providing information using a mobile internet terminal on anxiety, discomfort and satisfaction with education among patients undergoing a coronary angiogram. Methods: Data were collected from July 27, 2016 to February 23, 2017. A total of 64 participants (34 for the experiment group and 30 for the control group) admitted to a department of cardiology internal medicine for coronary angiography were recruited. Data were analyzed by SPSS Window 22.0 Program. Results: Information provided through mobile internet terminal did not affect anxiety and objective and subjective discomfort of the participants for coronary angiography, it was effective in satisfaction with education. Conclusion: Based on the results, it is indicated that video education using a mobile internet terminal could be an effective method to improve nurses' work efficiency and quality and to raise satisfaction with education.

In this paper, person monitoring and personal identification information management by using the location positioning device and the location management system based on GPS is analysed and developed. Mobile HTE(Mobile HTE : Mobile Home Terminal Equipment) of the developed system uses the module for transmitting PID(Personal Identification Device) information and the module based on GPS's location information. HTE transmits the received information from Mobile HTE to the Location Management System through the internet system. The Location Management System is developed for person location management and information management.

This paper describes the LBS Terminal Standard Platform based on WIPI. The LBS Terminal Standard Platform based on WIPI is API for obtaining the location information in the mobile standard platform providing the environment which is mounted on the mobile communications terminal and can platform an application. The mobile Platform consists of HAL API, C API and Java API that it is able to process Location Information data among wireless network. It is defined and developed at the HAL sections and C sections based on Generic I/O, and It describes in details in this paper. This standard Platform is expected to be utilized as the base specification in developing the LBS Terminal development technology and standard method to LBS application developers.

In this paper, we proposed availability evaluation of network in mobile communication network that have hand off structure. Radio mobile communication network is essential hand off action to keep communication that is no discontinuance by transfer of terminal. Part by state and hand off state ago hand off by transfer of terminal and communication network is estimated performance according to the hand off rate and hand off completion rate of system. we applied MS, SM, MM communication structure in radio CORBA for network availability evaluate. System availability in mobile communication network that can repair that propose in this study uses the hand off rate and hand off completion rate of system by transfer of terminal and availability of whole system did evaluate.

One of the particulars to be considered for providing wireless web service with PC web page is the hardware environment between PC and mobile device. It is because time cost is required in producing mobile contents to suit environment of the connected terminal. Therefore, server side should take account of response time and disk capacity of server. Response time is delayed by content conversion and disk capacity need to store various versions about one content. This paper suggests a pre-service and post-transcoding method to provide faster response time for a mobile terminal. The pre-service is to minimize response time by placing the top priority in servicing contents saved in cache as much as possible even if the quality of contents serviced to mobile terminal may be low. After pre-service is provided, the mobile content is transcoded for the terminal later. Performance level of method proposed was compared through experiment and the result of analysis was described.

In wireless mobile networks, the service area is partitioned into several registration areas (RAs). Every RA is associated with a mobility database called Visitor Location Register (VLR). The VLR is used to achieve the location management of the mobile terminals. When a mobile terminal enters a new RA, the VLR stores the current location information of the mobile terminal before serving any mobile services. At that time, if the VLR is full, the registration procedure fails, and the system can not deliver services to the mobile user under the existing cellular technology To resolve this problem, we propose a VLR overflow control scheme considering mobility of mobile users to accomodate incoming users during VLR overflow. The performance of the proposed scheme is evaluated by an analytic model in terms of costs for the location search and the location update, and compared with those of the overflow control scheme proposed by Lin[1].

Our paper deals with a method for supporting multiple call/sessions in a mobile terminal. The different identifier for each protocol layer is assigned to each session when a mobile terminal sets SDP for multimedia services. In particular, QoS based tasks are used for managing the traffics in radio interface. Also, queuing, admission control, load control, resource allocation and scheduling are done based on the priority of sessions. The various multimedia services which is different in the requirement of resource allocation are able to be serviced simultaneously because a mobile terminal can provide the various services based on this scheme.
