摘要： A resource control system of an access network and a transmission quality control method using the system are provided to enable quality control by mediating and controlling resources of the network, thereby offering QoS(Quality of Service) requested for communication between a contents provider and a contents user. A customer information collector(140) obtains information on QoS requested by a contents service and service subscription contents of a subscriber terminal. A communication network information manager(150) obtains network information including topology information of a network. A network controller(130) receives network setup information to reflect the received information on a network device. An acceptance controller(110) accepts usage of the contents service if a usage request for the contents service of the subscriber terminal is approved. A service policy unit(120) determines approval of contents service usage by using the obtained information, delivers the approval determination to the controller(110), and provides the network setup information in accordance with the determination.

摘要： PURPOSE: An apparatus for and a method of supplying IP level connectivity between Internet access terminals using ATM name server are provided to enable the communication between the subscriber's terminal in access to Internet and the other party's terminal regardless of whether the other party's ADSL terminal is accessing to Internet, by setting an IP level connection between the two terminals with a private Internet protocol address. CONSTITUTION: A domain name server(6-1) stores the name of a domain in the server provided in ISP network(3). An Internet access server(6-3) and an access server(6) are for the access to Internet. If the access server receives a service request from the subscriber of terminal A(1), the access server transmits the message of requesting IP address to the domain name server corresponding to the domain name of the terminal B(2) to the domain name server, receives the result and transmits the IP address of the terminal B to the terminal A. If the IP address is not included in the result received, the message of requesting for ATM address corresponding to the domain name of the terminal B is sent to the ATM name server operated in the ATM network. By using the ATM address of the terminal B received, the IP address allocation request message including the domain name of the terminal B and ATM address is sent to the Internet access server. If the IP address of the terminal B is received, the address is registered in the domain name server and is sent to the terminal A. Thus, regardless of whether the terminal B is accessing to Internet, the IP levels of the two terminals are connected by using ATM name server(6-2).

摘要： A system and a method for calculating a routing path for service admission control are provided to calculate the routing path by using network connection information which can be acquired through an IP(Internet Protocol) address assigning process for subscriber terminals and a network access process of the terminals assigned with the IP addresses, thereby performing the admission control capable of securing service quality between the subscriber terminals, received in the same region access network, without using a passive routing process and an SNMP(Simple Network Management Protocol). An edge router(51) is positioned at end of a network and connects concentrators, received in the same region access network, to the network. During a dynamic IP(Internet Protocol) addresses assigning process, for subscriber terminals(11~18) received in the concentrators, and a network access process, the edge router(51) collects network connection information. A control server(52) receives the network connection information from the edge router(51), and generates a logical connection structure between the terminals(11~18) and the edge router(51). When receiving a service admission control request, the control server(52) calculates the routing path between terminals(11~18) as service objects by using the logical connection structure.

摘要： PURPOSE: An ATM ADSL subscriber connection system and a method thereof are provided to set a PPP(Point-to-Point Protocol) session with a terminal by using a new NAS(Network Access Server), when an existing NAS setting the PPP session has a defect, and to assign a dynamic IP address to the terminal, thereby recovering IP level connectivity between the terminal and the NAS within the shortest time. CONSTITUTION: A DSLAM(22) receives a signal transmitted from a terminal(21), and multiplexes the received signal. An NAS A(23) receives the multiplexed signal, and integrates the received signal in transmissible type applicable to a backbone(24). An NAS B(25) sets a new PPP session with the terminal(21) when the NAS A(23) fails, and assigns a dynamic IP address. A subscriber connection DB(26) is assigned with IP addresses from the NAS A(23) and the NAS B(25), and stores information on the terminal(21). The backbone(24) collects signals transmitted from the NAS A(23) and the NAS B(25), and quickly transmits the collected signals.

摘要： PURPOSE: An apparatus and a method for controlling QoS of video service using dynamic resource allocation are provided to allocate resources of communication networks dynamically to improve utilization of the communication network resources. CONSTITUTION: An apparatus for controlling QoS of video service using dynamic resource allocation includes a traffic predictor(120), a QoS monitor(130), a dynamic resource manager(140), and a connection control manager(110). The traffic predictor measures each input video traffic to predict the next traffic. The QoS monitor discards the video traffic when the standby time during which the video traffic remains in a buffer exceeds the maximum packet transfer delay. The dynamic resource manager determines the band to be allocated to the video traffic at the next frame time according to the next traffic predicted by the traffic predictor, the number of delayed packets standing by in the buffer and QoS degree provided up to now. The connection control manager accepts connection of a new video source when Qos provided to all of existing connections is higher than a predetermined level and the sum of average input data rates of the connections is lower than an output link capacity allowance level.
摘要翻译：目的：提供一种使用动态资源分配来控制视频服务QoS的装置和方法，以动态分配通信网络的资源，提高通信网络资源的利用率。构成：使用动态资源分配来控制视频服务的QoS的装置包括业务预测器（120），QoS监视器（130），动态资源管理器（140）和连接控制管理器（110）。流量预测器测量每个输入视频流量以预测下一个流量。当视频流量保留在缓冲区中的待机时间超过最大分组传输延迟时，QoS监视器丢弃视频流量。动态资源管理器根据业务量预测器预测的下一个业务流量，缓冲区中的延迟数据包数量和现在提供的QoS度量，确定在下一帧时间分配给视频流量的频带。连接控制管理器在提供给所有现有连接的Qos高于预定电平并且连接的平均输入数据速率的总和低于输出链路容量允许级别时，接受新视频源的连接。

摘要： PURPOSE: A moving schedule management system based on time and location and a method thereof are provided to manage the moving schedule of a protected person by a combination of time and location, thereby grasping exactly the moving state of the protected person. CONSTITUTION: An information management unit(122) receives the moving schedule of a protected person based on location and time from a protector terminal(14). A location information receiving unit(121) receives the location information of the terminal(10) of the protected person. A schedule management unit(123) compares the location information and corresponding time information with the moving schedule. If deviation is more than a predetermined reference value between the moving schedule and an actual moving state, the schedule management unit creates an event. An information transmitting unit(124) transmits an event message corresponding to the event to the protector terminal.
