SIGNAL PROTOCOL STRUCTURE OF HOME LOCATION REGISTER

摘要

PURPOSE: A signal protocol structure of an HLR(Home Location Register) is provided to reduce delay generated in setting up a packet signal by taking an identical protocol structure for the signal plane and transmission plane of a GGSN(Gate GPRS Support Node) and a SGSN(Serving GPRS Support Node) and to achieve the simplification of a protocol by excluding a complicated common line signaling(CCS No.7) protocol. CONSTITUTION: The signal protocol structure of a packet data service node and a packet data gateway node is composed of a layer 1(570), a layer 2(560), an IP layer(550), a TCP/UDP layer(540), a TCAP layer(530), a MAP(Mobile Application Part) layer(520). The TCP in the TCP/UDP layer(540) is used for traffic in a transmission plane and the UDP is used for traffic in the transmission plane and for a signal message in a signal plane in common.
