  The present invention relates to a method for realizing a mobile gateway device used in a wireless communication network.

  Currently, there are various wireless communication networks such as the most popular GSM (Global System for Mobile communication) network, GPRS network and CDMA network. Since different operators have their own wireless communication network, different services, and customer base, no single operator network is complete in service and service area. Therefore, interconnections are required to achieve optimization settings and mutual complementation between different networks of operators. In order to perform network interconnections, mobile gateway devices are typically located in different networks like portals to other networks. However, existing mobile gateway devices only have modules that handle internal services and provide only interface interconnections. Therefore, the mobile gateway device performs only an internal network connection function, and it is difficult to manage and maintain various interfaces between networks. Since there is no universal external interface between different operator networks, network structure adjustment involves difficult external coordination work such as relays, signaling links and signaling data. It will be. As a result, overall resource utilization and network processing efficiency is reduced. Inter-communication and settlement between the operator's networks using existing mobile gateway devices must be performed through the mobile gateway device. Therefore, each private network requires its own mobile gateway device, which leads to an increase in settlement points, a complicated settlement relationship, and a decrease in network construction work.

  Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

  FIG. 1 is a block diagram of an embodiment of the present invention. The integrated gateway shown in FIG. 1 is an integrated operation / maintenance / support platform for services in fixed networks, GSM networks and CDMA networks. The integrated gateway effectively integrates all existing operation / maintenance functions in the network, provides unified signaling routing, relay routing and configuration functions, and combines with the routing gateway routing functions. The importance of the integrated gateway is that it achieves resource sharing and unified management and control.

  Referring to FIG. 2, an application environment of the integrated gateway is shown. As shown in FIG. 2, the integrated gateway serves as an integrated external interface to operators in order to connect to different communication networks of other network operators. For example, in FIG. 2, the operator's integrated gateway 1 connects with GSM MSC, CDMA MSC and the operator's IP front-end unit. Like the operator's local network (GSM network, CDMA network, data network, relay network and SMS network) and the interconnection gateway between other operator's network and enterprise private network, the integrated gateway is It functions as an interface to the network and performs authentication, accounting and settlement. The integration gateway serves as a shared gateway for all the operator's local networks and as the interconnection gateway between the operator's private networks, and the integration gateway interconnects the interfaces between the local networks. And responsible for authentication, accounting and settlement of accounts between the networks. Therefore, the integrated gateway does not simply add the functionality of the original gateway within GSM and CDMA networks, but instead provides a unified process for services, signaling, resources, operations & maintenance, traffic statistics and alerts. Integrate those gateways.

  FIG. 3 is an example of networking by the integrated gateway. As shown in FIG. 3, an integrated gateway connects the operator's different communication networks (eg, GSM network and CDMA network in FIG. 3), so that the integrated gateway can handle services in different communication networks. The SPCs within must be categorized and controlled centrally.

  The integrated gateway implemented according to the above requirements is shown in FIG. The universal integrated mobile gateway device for a wireless communication network includes AMP 1, CCM 2, CDP 3, SPC 4, 5, 6 and network interface 7. CCM 2 is connected to AMP 1, CDP 3 and SPC 4, 5, 6 respectively, AMP 1, CDP 3 and SPC 4, 5, 6 are connected to network interface 7 respectively, and CCM 2 is HDLC (High Data (Link Control) protocol is connected to AMP 1, CDP 3 and SPC 4,5,6, and the SPC 4,5,6 is connected to the network interface via TCP / IP (Transfer Control Protocol / Internet Protocol) protocol. Connected.

  The SPCs 4, 5, and 6 are F_SPC, G_SPC, and C_SPC, respectively, and the F_SPC4, G_SPC5, and C_SPC6 are connected to each other via an internal bus, and traffic convergence with respect to a physical entity, a gateway function, and fixed communication A system that is configured to realize SSP for each of the network, GSM network, and CDMA network, performs protocol processing on the layer above the link layer of SS7, DSS1, and No.1 signaling in the corresponding network, and the corresponding system Perform service processing within.

  AMP1 is configured to perform data collection and status collection for other modules. AMP1 receives all maintenance commands from the background module and performs processing and transfer of related commands, as well as monitoring status, management and failure processing for other modules.

  Along with AMP, CDP and SPC, CCM2 performs management of the data switching network and control data frame switching between modules.

  CDP3 is configured to store and manage relay resources and global shared resources.

  SPC4 processes services in different networks, realizes traffic convergence for physical entities, gateway functions, and SSP, and performs layer protocol processing on the link layer of SS7, DSS1, and No.1 signaling And service processing in the mobile switching system.

  As described above, two or more SPCs that handle different services are connected to the CCM via HDLC, the SPCs are connected to each other via an internal bus, and the SPC uses the TCP / IP protocol. To another network (for example, LAN) via serial HDLC. F_SPC, G_SPC, and C_SPC are connected to the CCM by serial synchronous HDLC. The F_SPC, G_SPC, and C_SPC are connected to the LAN by serial synchronous HDLC via the TCP / IP protocol. The F_SPC, G_SPC, and C_SPC are connected to each other through an internal bus. The SPC is realized by a single board module or a rack module.

  The SPC may be matched in physical design and logical design, but generic single boards, buses, interfaces and other generic devices may be difficult to match in design and equipment. That is, the series of integrated gateways may be realized by a general-purpose single board, a bus, an interface, and other general-purpose devices.

  When SPCs that match physical and logical designs are used as functional modules for different networks, the difference between those SPCs for different services will lighten the burden of processing the corresponding network services Well, it exists in the software. As shown in FIG. 4, the SPC mainly includes a minimum control system, a network port controller, a bus conversion logic module, a serial interface communication control module, and a mailbox controller. The minimum control system includes a CPU, a PCI-ISA bridge, a BIOS, and DRAM. The CPU module includes an AMD K6-2 CPU, a level 2 cache, a register TAG, and a PCI-CPU bridge. The CPU module uses a CPU bus for internal communication, and the PCI-CPU bridge performs conversion from the PCI bus to the CPU bus and provides a DRAM access interface. The PCI-ISA bridge performs conversion from a PCI bus to an ISA bus. DRAM is a storage medium for programs and data. The BIOS stores system initialization code and built-in support software BSP for the built-in operating system PSOS. The bus conversion logic module performs PCI32 to user-defined 32-bit bus conversion, and then provides a 24-bit address bus, 32-bit data bus, and partial I / O space. Use modules. The network port controller uses an Ethernet controller to perform conversion from a PCI bus interface to a 10/100 Ethernet control interface. Other network port controllers are also acceptable.

  The mailbox part of the SPC module comprises two parts. One part is used to interface with the motherboard bus and to communicate with the back plate or other card in the module via data transfer by HDLC HCC card . The other part is used to communicate with the HDLC control module. The serial interface CCM uses an HDLC communication control module. It is realized by a pinch plate HCC on the SPC module. The HCC comprises two MPC860 systems, each providing two 2M signaling buses (HW). The SPC module communicates with other modules via the HW. HCC also provides an escape serial port and an RS232 serial port for printing debugging information. The HCC also communicates with the SPC motherboard via the mailbox.

  When the integrated gateway shown in FIG. 1 is applied in the environment shown in FIG. 2, the call processing between different networks is as follows.

  When a user in an external network calls an integrated operator's CDMA network user, the call is routed from the external network to the integrated gateway (path 1) and routed from the integrated gateway to the operator's CDMA network. (Pass 3).

  In pass 1, the user in the external network initiates a call for the operator to the CDMA network user. The call is routed through the gateway of the external network to the operator's integrated gateway. And in path 3, the integrated gateway determines whether the called user is a CDMA network user according to the characteristics of the calling user, and makes a call on the SPC that processes the CDMA service (C_SPC). to set up. The call is then routed to the internal CDMA network via a normal CDMA call procedure.

  When the operator's GSM network user calls the operator's CDMA network user, the call is routed from the GSM network to the integration gateway (path 2) and from the integration gateway to the CDMA network. (Pass 3).

  Initially, in pass 1, the GSM network user initiates a call to the CDMA network user. The call is routed to the integration gateway. Next, in path 3, the integrated gateway determines whether the called user is a CDMA network user according to the characteristics of the called user and processes the CDMA service (C_SPC). Set up the call at. C_SPC routes the call to the CDMA network via a normal CDMA call procedure.

  If an external network user calls the operator's GSM network user, and the called user roams within the operator's CDMA network, the call is routed from the external network to the integrated gateway. (Path 2) and then routed from the integrated gateway to the CDMA network (path 3).

  First, in path (1), the user in the external network initiates a call to the GSM network user. The call is routed from the gateway of the external network to the operator's integrated gateway. And in path 3, the integrated gateway determines whether the called user is a GSM network user according to the characteristics of the called user, and on the service module that processes the GSM service (G_SPC) Set up the call. When G_SPC searches for a roaming number, it can be seen that the GSM user is roaming into the CDMA network. Therefore, G_SPC forwards the call to the service module that processes CDMA service (G_SPC) by the internal interface. Finally, G_SPC routes the call to the CDMA network via a normal CDMA call procedure.
