Abstract: PURPOSE: A proxy server device for a mobile multimedia service is provided to enable a proxy server to function as a termination of a mobile multimedia subsystem by separating functions of a mobile communication network and a mobile multimedia network, thereby easily adding a service logic or expanding a network node in the mobile multimedia network. CONSTITUTION: An SIP(Session Initiation Protocol) processor(111) receives an SIP message from a mobile terminal. An SIP access processor(112) interfaces the SIP processor(111) with an upper application layer. A DNS access processor(114) is used to know an address of a location register having location information of the mobile terminal. A policy controller(113) controls a new QoS bearer setup with a mobile communication network according to QoS changes. A proxy server call controller(115) carries out a call processing procedure. A subscriber information manager(116) connects the proxy server call controller(115).

Abstract: PURPOSE: A device for performing IPC(Inter Process Communication) under a distributed process environment is provided to process received wireless traffic data and control data by an interrupt method, and to transmit the data within suggested time through a buffer, thereby easily transceiving the data. CONSTITUTION: An IPC module(200) receives wireless traffic data and control data received from a lower device driver(100) by an interrupt method to process the data, and transmits the processed data within time suggested according to transmission order. An IPC API(Application Program Interface)(300) interfaces the transmitted data, transmits the interfaced data to an application module(400), and interfaces transmission data of the application module(400), then transmits the data to the IPC module(200).

Abstract: PURPOSE: A method for embodying an I/O is provided to implement a high availability by using a real time operating system for developing a system satisfying a high availability and a middle ware being operated at the upper portion thereof rapidly and cheaply. CONSTITUTION: A HAC(high availability channel) transmits and receives high availability control data at the least significant layer. An Ethernet interface block transmits and receives an Ethernet. An ATM interface block is provided for ATM transmission/receipt. In addition, a hierarchy for processing a BSP(board support package), a RTOS(real time operating system) and kernel hierarchy, and a HAM(high availability manager) are provided. An area storing IOHT(I/O history table)(synchronization information) sharing for adjusting a synchronism between an active node and standby node is separated from a general memory area, and continuously flushing of the area is performed. A synchronism is adjusted by transmitting and receiving IOHT prepared based on an I/O through the HAC. Messages are transmitted and received between the HAMs of the active node and the standby node, and if a trouble is generated, a switching is performed from the active node performs to the standby node.

Abstract translation: 目的：提供一种实现I / O的方法，通过使用实时操作系统来开发满足高可用性的系统和在其上部快速且便宜地操作的中间件来实现高可用性。 构成：HAC（高可用性通道）在最低有效层发送和接收高可用性控制数据。 以太网接口块发送和接收以太网。 ATM接口块用于ATM发送/接收。 此外，还提供了用于处理BSP（板支持包），RTOS（实时操作系统）和内核层次以及HAM（高可用性管理器）的层次结构。 存储用于调整主动节点和备用节点之间的同步的IOHT（I / O历史表）（同步信息）共享的区域与一般存储区域分离，并且连续地刷新该区域。 通过HAC发送和接收基于I / O编写的IOHT来调整同步。 在主动节点的HAM和备用节点之间发送和接收消息，如果生成故障，则从主动节点执行到备用节点的切换。
