네트워크 사용자들의 다양한 요구를 수용하고 신뢰성이 있는 서비스를 제공하기 위하여 많은 통신 사업자들은 SLA(Service Level Agreement)를 제공하고자 하고 있다. 통신 사업자들은 다양한 네트워크 서비스를 제공하고 있으며 각 네트워크 서비스에 대한 SLA 를 제공하기 위한 SLA 시스템은 유연한 구조를 가져야 한다. SLA 서비스는 계속적인 상황 감시를 통해 서비스 이용자와 계약 상황이 지켜질 수 있도록 해야 한다. 이를 위해서는 SLA 시스템 운용자의 부재시에 운용자에게 긴급 상황을 알려 주는 SMS(Short Message Service) 제공이 필요하다. SLA 시스템 운용자는 여러 등급이 존재하며 관리해야 하는 사항과 서비스도 다양하다. 이런 경우를 고려하여 효과적인 SMS 기능을 SLA 시스템 운용자에게 제공하는 SMS 기능을 본 논문에서 설계하고 구현하였다.

We have used SMS to exchange messages between mobile phones. Since the network evolved to the ALL-IP network, the next generation messaging service, RCS, has emerged to the market. Because SMS and RCS coexist, we need to inter-work the messages between SMS users and RCS users. This paper introduces a message inter-working framework(MIWF) that can inter-work SMS and RCS without changing end user's UX. It defines the call flows between the network equipment and MIWF. Also, it shows how MIWF converts messages between 3 protocols. Performance evaluation proves that MIWF does not add loads to the existing network.

The Short Message Service (SMS) is one of the most popular communication tools in the world. As the cost of SMS decreases, SMS spam has been growing largely. Even though there are many existing studies on SMS spam detection, researchers commonly have limitation collecting users' private SMS contents. They need to gather the information related to social network as well as personal SMS due to the intelligent spammers being aware of the social networks. Therefore, this paper proposes the Social network Building Scheme for SMS spam detection (SBSS) algorithm that builds synthetic social network dataset realistically, without the collection of private information. Also, we analyze and categorize the attack types of SMS spam to build more complete and realistic social network dataset including SMS spam.

In this paper planed Secret Single Message Service using MVLS(Multipurpose Visual Language System) for conceal contents to other persons that based on national institutions and private organizations report. This system is not persue to important contents like national or company's secret, but merely just decode to general and conceal SMS that using peoples at real life. This system is have an advantage that encoding to message like between lover's conversations or dislike contents to view the other persons, only can see own users that is to keep private life. Also, this system offers convenience to users that using general SMS service and only activate On-Off function for secret mode to user's needs.

SMS service is widely used for providing the approval information of a credit card when the payment is made by a credit card. But the message contained in the SMS is very simple and includes one time approval information. Although detailed approval informations could be retrieved by means of wire-network or mobile network services, the wire-network service could not be used on moving and the mobile network service requires high cost. In this paper, a WIPI application program managing the approval informations of a credit card based on the accumulated SMS messages in the cell phone has been developed. A cell phone user can conveniently can get the useful information such as the approval list on last month, the approval list on this month, the total amount on this month and the information about payment by installment from the developed program without any cost.

The network configuration of SMS number moving service is a very important factor to improve the user convenience to Internet Telephone. To provide the service, The SMSC system is required the the function of DB process and management of the subscriber, In case of SMSG system to interconnects with the other network and SMSC, the function of the call processing of subscriber who has changed his number by interconnecting with NPDB(Number Portability DB) is required. This paper had studied the way to consist the efficient network by the number moving technique.

Purpose: The purpose of this study was to determine the effects of self-care program using Short message service (SMS), e-mail, or telephone call on self-care compliance and nutritional status in maintenance of hemodialysis patient. Methods: Nonequivalent pretest-posttest control experimental design was used. Ninety-six patients were allocated to control (n=24), SMS (n=24), e-mail (n=24), or telephone (n=24) group from four hospitals. Experimental groups received self-care program about hemodialysis diet, drug administration, exercise, and fistula care by SMS, e-mail, or telephone call respectively at 3 times a week for 4 weeks. Results: Subjective self-care compliance, and objective self-care compliance including interdialytic weight of SMS and telephone groups were significantly increased than those of control groups. However, nutritional status of SMS and e-mail groups were significantly improved than those of control groups in albumin and protein level. Conclusion: Self-care program using SMS and telephone call were effective on promoting self-care compliance, while SMS and e-mail were effective on improving nutritional status. The pop-up remaining effect and easy accessible effect of SMS message in busy daily life was considered as an alarm to control fluid and diet.

Purpose: The purpose of this study was to investigate the effect of a short message service intervention on adherence to maximal barrier precautions (MBP) and catheter-related blood stream infections. Method: The data were collected from March to September, 2008, at an 826-bed university-affiliated hospital in Daejeon. The study participants were 24 physicians who were inserting central catheters and 133 patients (control group 78 and intervention group 55) with central catheter insertions. The researcher sent the message (adherence to MBP and optimal recommendations) to each internal medicine doctor using the short message service (SMS) for cellular phones. Messages were sent monthly for 3 months. Data were analyzed by chi-square test and t-test using SPSS 12.0 windows program. Result: Adherence to maximal barrier precautions was significantly increased from 44.9% to 69.1% (p=.006) after the SMS intervention. But changes in the rate of CRBSI (catheter related blood stream infection) between the intervention group (1.89) and the control group (4.45) were not significant (p=.323). Conclusions: The results indicate that the SMS intervention is effective in increasing the adherence to maximal barrier precautions and the SMS intervention can be recommended for utilization in infection control nursing practice.

무선 단문전송 서비스(SMS : Short Message Service)란 이동 통신 세계화 시스템의 규격을 따른 무선 호출 서비스로 별도의 부가장비 없이도 40자 내외의 짧은 문장을 주고받을 수 있는 문자 서비스이다. 휴대전화의 보급이 급속도로 확산되면서 이에 비례해 문자 서비스 이용 인구도 급속히 늘어나고 있는데, 이메일과 달리 발송 시점과 거의 동시에 내용 전달이 가능하기 때문에 현재 통신수단의 하나로 이미 확고한 자리를 굳힌 상태다. 또한 근래에는 산업현장에서도 알람이나 FAULT정보 등의 신속한 전달을 위해 SMS에 대한 요구가 높아지고 있다. 이러한 시장의 동향에 따라 본 연구소에서는 산업 현장에서 알람이나 알림, 시스템 FAULT등 긴급한 사항에 대한 단문전송 프로그램을 개발하게 되었다.

This dissertation proposes method for development technology of voice and SMS(Short Message Service) alarming system based on modbus protocol. The proposed technology is composed of the following 3 stages; hardware development based on microprocessor, development of input and output driver for modem, mp3 decoder, making modbus protocol stack. In the stage of hardware development based on microprocessor, we develop hardware which receives alarm from modbus master and transmit sms message, play mp3. In the stage of development of input / ouput device driver such as modem, mp3 decoder, we develop program which control each devices. In the stage of making modbus protocol stack, voice and sms alarm system is made for receiving alarm via modbus protocol. To evaluate performance of proposed technology, we issued alarm to voice and sms alarming system on purpose. As a result, response speed of detecting alarm was 10.7ms, communication distance was 1.2Km, operating temperature was from $-25^{\circ}C$ to $70^{\circ}C$, we confirmed supporting modbus protocol. And we verified that proposed voice and sms alarming system in the thesis has a performance to be used as an industrial building alarming system.
