Abstract

An HLR(Home Location Register) system for supporting both a trunk-based network interface and an IP-based network interface is provided to offer voice/supplemental services to mobile subscriber, regardless of interface types, by enabling IP-based interfacing with other systems. An HLR system in a CDMA mobile communication system comprises the first network interface, the second network interface, an SCCP(Signaling Connection Control Point)(200), and an SS7(Signaling System No.7) stack management part(100). The first network interface is an E1-based network interface. The second network interface is an IP-based network interface to access an IP-based remote system. The SCCP stores received table information. If a signaling message for a mobile subscriber voice/supplemental service is generated, the SCCP confirms the received table, selects a remote system, and checks the interface type of the remote system. In case the remote system uses a trunk-type interface, the SCCP transmits the signaling message to an existing MTP3 processing part(30). However, if the remote system uses an IP-type interface, the SCCP transmits the signaling message to an M3UA processing part(300). In case that signaling messages from a remote system are received through an IP network, the SS7 stack management part manages each table so as to transmit them to an upper layer through the second network interface and to execute signaling message processing, and provides table information to the second network interface. Also the SS7 stack management part provides table information containing the network type information of the remote system to the SCCP.

TABLE 4

TABLE 5

The SCCP 200 stores network type information of the power system received from the SS7 stack manager 100 and selects a power system to send the signal message when a signaling message for mobile subscriber voice / additional service occurs. After that, the interworking method of the system is inquired, and the relay line method transmits the signal message to the existing MTP3 processing unit 30 and, in the case of IP method, transmits the signal message to the M3UA processing unit 300.

The ASE performs voice / additional service functions, and the MAP performs CDMA specification analysis and processing.

The TCAP 60 performs a transmission / reception management function of a signaling message.

General functions and detailed operations of the above-described elements will be omitted, and the operations will be described with reference to FIG. 4 based on the operations corresponding to the present invention.

First, the SS7 stack management unit 100 is ASP information, and includes a first table constituting ASPID for satisfying the M3UA standard, PIPADDR and SIPADDR for multihoming, SCTP connection port number, and COMSGPCNT and FSTSGPIDX for efficient management. 110); For SGP information in the SG system, the SGPID, IPADDR to connect with ASP, Trf mode and NwApp information including traffic mode and network appearance for connection properties, and SCTP connection port information are configured to satisfy the SG system specification.
