Ip网络系统中的节点跨区域呼叫方法

Pitch point transregional call method in IP network system

Abstract

Node area crossover calling method for IP network system includes registering for each H.323 node of gatekeeper with another E.164 name in advance, which consists of the only node sequential no. of the gatekeeper plus the area prefix no.; directly calling the called node by H.323 node calling with the E.164 name of the called H.323 node; extracting the prefix no. of the called node and providing the called gatekeeper with an inquity to analyze the IP address of the called node; returning the analyzed IP address to the calling node; transmitting a set up command by the calling node and starting calling.
本发明涉及一种IP网络系统中的节点跨区域呼叫方法,可简单方便地实现跨网守(GK)区域的节点寻址与呼叫。包括:在IP网络系统中的每一个网守(GK)上预先注册网守(GK)中每一个H.323节点的E.164别名,由一个在IP网络系统中唯一的区域前缀号加上在网守(GK)中唯一的节点编号组成;主叫H.323节点利用被叫H.323节点的E.164别名直接呼叫被叫节点。主叫GK提取出被叫节点别名中的前缀号,向被叫GK发出解析被叫节点IP地址的请求;被叫GK将解析出的被叫节点IP地址,返回给主叫GK;主叫GK将被叫节点的IP地址通知主叫节点;主叫节点根据该IP地址向被叫节点发送建立指令(setup),开始呼叫。
