Abstract: 본발명은여러명의참여자들이존재하는그룹통신에서송신자별로다른서비스품질로데이터를송수신할수 있도록하기위한서비스품질(QoS) 협상방법에관한것이다. 이러한그룹데이터송수신에서송신자별이종서비스품질을지원하는서비스품질협상방법은, 여러명의참여자들이존재하는그룹통신에서모든송신자들이상호독립적으로수신자들과서비스품질을협상하는방법에있어서, 모든송신자들이개별적으로자신의시스템능력에맞게수신자들과서비스품질을협상하여최적의 QoS 값을설정하는제 1 단계와, 상기모든송신자들의서비스품질협상이완료되면모든송수신자가협상된모든 QoS 값들중 토큰의개수만큼의고품질의 QoS 값들을합산하는제 2 단계와, 상기합산결과값으로부터자신의시스템에서감당할수 있을만큼의토큰의개수를설정하여데이터를송수신하는제 3 단계를포함한것을특징으로한다.

Abstract: PURPOSE: A method for managing a group membership is provided to easily manage a membership in an internet multicast application based on an IP multicast description, and to accurately grasp information on participants who participate in a multicast group by partially extending an SDP, and by providing a GMP which performs a group management function. CONSTITUTION: A group manager client generates group information and transmits the information to a group manager server. The client makes requests for a group registration, and performs the group creation and the group registration. The server officially announces the group created using a multicast group address. A group manager client who knows a group identifier asks the group information of the server and obtains an answer thereof. A group manager client who doesn't know the group identifier joins a public group address and obtains group information received to the group address. The client performs a participant enrollment to the server. The client registered as the participant transmits information on a group leave. The server transmits information on a failure cause to the client. The client divides the request signal into several fragment messages.

Abstract translation: 目的：提供一种用于管理组成员身份的方法，以便基于IP组播描述容易地管理因特网组播应用中的成员身份，并通过部分扩展SDP来准确地掌握参与组播组的参与者的信息，并通过提供 执行组管理功能的GMP。 构成：组管理客户端生成组信息并将信息发送到组管理器服务器。 客户端请求组注册，并进行组创建和组注册。 服务器正式宣布使用组播组地址创建的组。 知道组标识符的组管理客户端询问服务器的组信息并获得答复。 不知道组标识符的组管理器客户端加入公共组地址，并获取接收到组地址的组信息。 客户端执行与服务器的注册。 注册为参与者的客户端在组休假时发送信息。 服务器将有关故障原因的信息发送给客户端。 客户端将请求信号分成几个片段消息。

Abstract: PURPOSE: A visualizing device and method for digital signature is provided to transfer digital signature to easy recognizable form. CONSTITUTION: A visualizing device for digital signature(2) receives an electronic document from a creation device of digital signature. A coding module(12) in the visualizing device for digital signature is composed of an interface module, a QP(Quoted Printable) module, bar coding module, and a user defined module. The coding module(12) receives and codes an open key, a coded signature value, and a tag number following variant coding method. A position selection module(22) visualizes the coded data such as open key, tag value, digital signature value a paper. Also, the position selection module(22) decides the position and the size when the coded data is visualized.
