Abstract

PURPOSE: A method for updating local network IP addresses in a mobile switching system is provided to modify and update local network IP address using PLD(Programmable Loading Data) among the packet data transmitted to upper/lower layer systems so as to easily modify network IP addresses even though a mobile switching system does not have a domain server or a router function. CONSTITUTION: A CCP(Call Control Processor) downloads an operating system, a protocol program and other application programs from a BSM(Base Station Manager) and reboots them. In case that a modification for a network configuration element is required, the CCP updates the element after revising/modifying it(S1,S2). Then the CCP judges whether the network elements of the presently downloaded routing table and host table are newly configured(S3). If a newly configured network element exists, the CCP downloads new network configuration element information from the BSM using PLD(S5). The CCP updates the existing routing table and host table through the downloaded new network configuration element information, and modifies a network configuration value according to this new information(S6). Then the CCP resets up a network environment using the presently revised/modified network configuration element information(S7).

Description

Method for updating a local network IP of the mobile communication switching system}

The present invention relates to a method of updating a local network IP of a mobile switching system, and in particular, by modifying, changing, and then updating an IP address of a corresponding local network by using a PLD among packet data transmitted to upper and lower hierarchy systems. The present invention relates to a method for updating a local network IP of a mobile switching system that can easily change an IP address of a corresponding network even when the system does not have a domain server or a router function, thereby improving the functionality of the mobile switching system.

In general, as the industrial society develops, information communication systems are widely used to transfer data from one point to another desired more appropriately and quickly. Such communication systems are usually homogeneous or heterogeneous communication devices which are geographically dispersed. In most cases, information devices are connected to a network to enable sharing and communication of resources. In addition, such a network system, in particular, a mobile communication exchange system uses the TCP / IP protocol to transmit and receive data to different networks, wherein the system using the TCP / IP protocol is a variety of IP that the routing destination is set in the internal table It contains their information.

Then, referring to FIG. 1, a mobile communication switch system using the TCP / IP protocol is used. The ATM switch generates an internal table including various IPs for routing using the TCP / IP protocol and transmits the data to a corresponding network element. The base station 71A-N which executes a set function, for example, fault alarm data transmission by searching the packet data including the system 70 and the internal table transmitted from the ATM switching system 70 and confirming the corresponding IP. Include.

In addition, one end of the ATM switch system 70 may be connected to a gateway 73 for connecting a transmission signal to an external communication network, for example, the Internet 72.

Here, the internal table is set with a corresponding host IP address, a local host IP address, a network submask value, and an Ethernet hardware address value.

On the other hand, referring to the routing method of the mobile communication switch system using the conventional TCP / IP protocol as described above, first, when the ATM switch system 70 is set up, the operating system program for booting is an upper protocol program and other application programs. It is downloaded from the BSM (not shown: BASE STATION MANAGER) and stored in the hardware local memory area. The storage also stores a routing table and a host table including network elements according to the network configuration. When the TCP / IP protocol of the processor of the ATM switch system 70 transmits a call signal to the outside, the TCP / IP protocol searches the network-related table and transmits the IP address and network mask value of the call signal transmitted to the outside of the switch. . For example, when the call signal is transmitted to a specific base station 71A, the processor of the base station 71A retrieves a routing table of packet data transmitted from the ATM switching system 70, and their values and its local subnetwork. Determine if it matches the value. In this case, when the values of the two base stations 71A match, the functions included in the corresponding packet data are performed. On the other hand, if the value of the routing table and the value of the local subnetwork do not match, no communication is performed. During the process, if the call signal destination of the routing table is an external communication network, for example, the server 74 of the Internet 72, the processor of the ATM switch system 70 transmits the packet data of the call signal to the gateway 73. do. Then, the gateway 73 converts the input packet data into a communication signal associated with an external Internet network, and transmits the packet data to the server 74 of the IP recorded in the routing table through the Internet 72 to process a normal signal. do.

However, the routing method of a mobile communication switch system using the conventional TCP / IP protocol as described above should be updated by changing a new local subnetwork IP in a changed network element, for example, a routing table. If it doesn't exist, you have to run a new program to do this.

In addition, since the routing table is fixedly assigned to the local memory area of the TCP / IP protocol, if there is no router in charge of the gateway, the network mask value or other IP of the routing table in the routing table is fixed. Since the IP address of the packet data is changed and the IP address of the packet data is changed and transmitted and received, the newly allocated IP is not recognized and the data is lost.

Accordingly, the present invention has been invented to solve the conventional problems as described above, by modifying and changing the IP address of the corresponding local network by using the PLD of the packet data transmitted to the upper and lower hierarchical system, and then update the mobile communication switch. Even if the system does not have a domain server or router function, the purpose of the present invention is to provide a method of updating a local network IP of a mobile switching system that can easily change the IP address of a corresponding network, thereby improving the functionality of the mobile switching system. .

Another object of the present invention is to provide a method for updating a local network IP of a mobile communication exchange system, which can easily handle a network IP change function without complicated hardware operations, thereby improving convenience of a mobile communication system.

In order to achieve the above object, the present invention provides a network component updating step of updating / modifying / modifying a network component using a PLD of a BSM when there is a change in the network component during initial program loading of the mobile communication switch system. If there is a newly configured network component after the network component updating step, a new network component downloading step of downloading the updated new network component information using the PLD from the BSM, and the new network component downloading step The local network of the mobile switching system including the step of updating the network configuration information preset with the new network component information loaded from the BSM and resetting the environment of the network according to the new information. Efficient way to provide updates.

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

The mobile communication switch system to which the present invention is applied is provided in the ATM switch system 1 as shown in FIG. 2 to perform an executable file downloading function for processing call signals, and to change and delete network elements of a specific routing table. And a base station manager (BSM) for downloading a PLD (programmable loading data) to be updated, and being provided in the ATM switch system 1 to download an executable file from the BSM 2 to execute a corresponding function. A call control processor (CCP) and a base station processor (BSP) of the base stations 4A-N resetting the network environment by retrieving a routing table updated by the PLD input from the CCP 3. do.

Here, the configuration of the PLD is a database in a loading data format including routing / host information and information of network components.

Next, a method applied to the mobile communication switch system as described above will be described.

First, the method of the present invention proceeds from the initial state (S1) to the program loading step (S2) as shown in Fig. 3 to determine the operating system, protocol and application program to be run in the actual local memory of the mobile switching system from the BSM. After downloading and rebooting, if there is any change of network component, update it by modifying / changing network component using PLD of BSM.

That is, when the ATM switch system 1 is set up, a booting operating system program and a boot loader program built in the boot ROM (not shown) of the CCP 3 are initialized. The CCP 3 downloads an operating system, a protocol program, and other application programs to be run in real local memory (not shown) from the BSM 2 according to a boot loader program and stores them in a hardware local memory area. In addition, when the downloading operation from the BSM 2 is completed, the CCP 3 transmits each downloaded program to the BSP 5 of each base station 4A-N and stores it in the corresponding local memory area. Let's do it.

Then, each processor 5 reboots and lists the program loaded into the local memory area according to the boot loader program. Each of the processors 5 runs an operating system, a protocol and an application program of the local memory, in which a routing table and a host table are basically set up. During this process, if the network components in the routing table and the host table are changed or modified, such as their host IP, local host IP, network mask value, Ethernet hardware IP, number of local hosts and other network element reservation values, etc. If necessary, the network manager uses the PLD of the BSM (2) to modify / change their information and then update and apply it.

On the other hand, after the program loading step (S2) to proceed to the new network component determination step (S3) to determine whether the network elements of the currently loaded routing table and host table is newly configured. As a result of the determination during the new network component determination step (S3), if there is no newly configured network component among the network elements of the currently loaded routing table and the host table, the process proceeds to the general call signal transmission step (S4) and is currently loaded. The received call signal is transmitted to the corresponding destination according to the IP information of the network written in the routing table and the host table.

That is, the CCP 3 of the ATM switch system 1 sends the BSP 5 of each base station 4A-N when network components in the routing table and host table loaded from the BSM 2 have not changed. Transfer it and set it in the local memory area. In this case, the CCP 3 transmits packet data indicating a signal for a specific operation, for example, a failure determination data transmission request, to the BSP 5 of an arbitrary specific base station 4A, using the TCP / IP protocol. The data is sent to the BSP 5 of 4A. Then, the BSP 5 of the base station 4A receives network elements of the routing table and the host table in the packet data input from the CCP 3, for example, its host IP, local host IP, network mask value, This packet data is executed if the Ethernet hardware IP, the number of corresponding local hosts, and other network element reservations are compared with the settings previously stored in the local memory. That is, the failure determination data requested by the CCP 3 is prepared and transmitted to the CCP 3.

However, if there is a newly configured network component among the network elements of the currently loaded routing table and host table as a result of the determination in the new network component determination step S3, the process proceeds to the new network component downloading step S5. Download the updated new network component information from the BSM using the PLD. After the new network component downloading step (S5), the process proceeds to an information update step (S6) to update the existing routing table and the host table with the new network component information loaded from the BSM, and according to the new information, Change the configuration value. In addition, after the information update step (S6), the process proceeds to the update application step (S7) to reset and apply the network environment by the network component information currently changed / modified.

That is, the CCP 3 of the ATM switch system 1 sends a loading request signal to the BSM 2 when there is a newly configured network component among the network elements of the currently loaded routing table and the host table. send. When the CCP 3 receives a loading request ack signal from the BSM 2 and the BSM 2 downloads the updated new network component information using the PLD, the loading data is loaded. Format and store in local memory, and when loading is complete, the loading completion signal (loading end signal) is transmitted to the BSM (2). After downloading the new network component, the CCP 3 transmits this information to the BSP 5 of each base station 4A-N for application. That is, the BSP 5 of the base station 4A-N updates the existing routing table and the host table with new network component information transmitted from the CCP 3 and changes the configuration value of the network according to the new information. The network environment is reset and applied according to the current changed / modified network component information.

Therefore, according to the present invention, when information such as network IP address, network mask value, lower hardware address value or the like is required, a user or a network manager can easily change and update their information using the PLD of the BSM 2. If it is given, the mobile communication exchange system downloads it at the initial boot and automatically resets and applies the environment.

As described above, according to the present invention, when the IP address of the corresponding local network is modified, changed, and updated by using the PLD among the packet data transmitted to the hierarchical system, the mobile switching system does not have a domain server or router function. Even if the IP address of the network can be easily changed, there is an advantage in improving the functionality of the mobile switching system.

In addition, according to the present invention, since the network IP change function can be easily processed without complicated hardware operations, the convenience of the mobile communication system can be improved accordingly.
