BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to data path setting in an access gateway, and in particular, one host system (HS) and a plurality of remote systems (connected via two or more gateways (G / W)). Due to the variable shape application between the Remote System (RS), it detects the gateway gateway (G / W) which is not defined yet and establishes the communication path to variably connect the internal system and the multiple remote systems (RS). An apparatus and method for automatically setting a data path at an access gateway suitable for the following.

In general, the Access Gateway system is the next generation, such as International Mobile Telecommunication in the year 2000 (IMT-2000) or Code Division Multiple Access (CDMA) 1x Evolution Data Only (EVDO). It refers to the wireless Internet infrastructure system supporting the wireless network.

1 is a block diagram showing the shape of a host-remote system in a conventional access gateway.

Here, reference numeral 10 denotes a host system (HS), 11 denotes a main processor (MP) which performs main functions in the host system 10, and 12 denotes a gateway G / in the host system 10. W).

In addition, reference numeral 20 is a plurality of remote systems (RS) connected to the gateway (G / W) 12 of the host system 10, respectively, 21 is a main processor for performing a main function in the remote system 20 (MP), and 22 is a gateway (G / W) located in the remote system 20 and connected to the gateway 12 of the host system 10.

Thus, as shown in FIG. 1, in a host-RS structured system in which a plurality of RSs 20 are connected to one HS 10, each RS 20 has its own address to communicate with the HS 10. do.

In this case, since the main processor (MP) 11 of the HS and the main processor (MP) 21 of the RS 20 cannot be directly connected to each other, they pass through one or more gateways G / W.

Therefore, each of the main processors (MPs) transfers data to a next stage gateway (G / W) which is predetermined for communicating with the target system, and then the gateway (G / W) is the next stage gateway (G). / W) continuously deliver the data, which is finally delivered to the target main processor (MP).

2 is a block diagram showing a data path setting in a conventional access gateway.

Thus, as shown in Figure 2, the conventional HS (10) and RS 20 is based on the order according to the system map (plan) of the ports of the HS gateway (G / W) 12 connected to each RS in advance Is specified.

That is, the port of HS gateway (G / W) 12 connected to RS # 0 is always Port # 0 of G / W # 0, and the port connected to RS # 15 is Port # 3 of G / W # 3. This is an example of the shape of a 4 port / 1 gateway.

Therefore, if a data transfer is attempted from the main processor (MP) 11 of the HS 10 to the main processor (MP) of RS # 0, the main processor (MP) 11 of the HS 10 is HS G / W. Data is sent only to # 0, and HS G / W # 0 checks the destination address and forwards the data to Port # 0, which is a port defined by a predetermined system map.

Thus, data leaving HS G / W # 0 is transferred to RS gateway (G / W) and transmitted to RS main processor (MP).

Even when data is transferred from the main processor MP of the RS 20 to the main processor MP 11 of the HS 10, the gateway G / W of the intermediate process is already determined. In this case, the data leaving the RS gateway (G / W) is transferred only to Port # 0 of G / W # 0 of the HS gateway 12, and this data is transferred to the main processor (MP) 11 of the HS (10). Final delivery.

However, this conventional technology has the following problems.

That is, since the system map is predetermined, it is not possible to change the system shape and waste of resources requiring an unnecessary gateway (G / W) may occur even when deleting the intermediate RS.

3 is a block diagram showing the problem shown in FIG.

So, as shown in Figure 3, because of the shape change, even when operating only two systems of RS # 0 and RS # 5 can be operated only by a predetermined system map, even though only two ports are used, two gateways (G / W) and waste the remaining six ports.

In the extreme case, four host gateway (G / W) devices must be provided to configure four RSs, and there is a problem that as many as twelve ports are wasted.

Accordingly, the present invention has been proposed to solve the above-mentioned general problems, and an object of the present invention is still due to the variable shape application between one host system and a plurality of remote systems connected through a gateway of two or more stages. The present invention provides an apparatus and method for automatically setting a data path in an access gateway capable of variably connecting an internal system and a plurality of remote systems by finding an undefined gateway gateway by itself and establishing a communication path.

This table shows an example of receiving information about.

As shown here, the host / remote discriminating unit 41 determines whether the current position belongs to the host system HS or the remote system RS by using the system identification (Identification); A host configuration information receiver 42 which receives host configuration information when the host / remote discriminating unit 41 determines that the host / remote discriminator 41 belongs to a host system HS; A gateway gateway searching unit 43 for searching for a gateway G / W if the host / remote discriminating unit 41 determines that the device belongs to a remote system RS; And a system map setting unit 44 for receiving a signal from the host configuration information receiving unit 42 and the gateway gateway searching unit 43 and setting a system map to configure a gateway (G / W). .

The automatic data path setting device in the access gateway is installed in the host system (HS).

The automatic data path setting device in the access gateway is installed in the remote system (RS).

The host configuration information receiver 42 receives the host configuration information, reads the destination address of the corresponding data, and informs the system map setting unit 44 of the host configuration information.

In the above, the gateway gateway searching unit 43 searches for the gateway of the gateway by repeatedly transmitting a polling method to the gateway of the gateway.

The second step may further include setting a system map after receiving host configuration information and reading a destination address of the corresponding data.

The third step may include: polling the gateway gateway to determine whether there is a response from the gateway that is aware of the remote system (RS) connected thereto (ST5) (ST6); If there is a response, a step of setting a system map by registering the gateway to which the response is provided as a gateway is performed (ST7).

An apparatus for automatically setting a data path in an access gateway and a method thereof according to the present invention configured as described above will be described in detail with reference to the accompanying drawings.

First of all, the present invention is intended to variably connect a domestic system with a plurality of remote systems.

Thus, while the present invention maintains the shape of the host system (HS) and the remote system (RS) as in the prior art, as shown in FIG.

To do this, the same gateway device has a selection mechanism that can be used selectively according to HS and RS.

In addition, the HS gateway 40 does not have a preconfigured system map, and operates by the host configuration information receiver 42 capable of changing the map by receiving setting information according to a situation, and the RS gateway 50 searches ( Scan) algorithm is applied to operate by the gateway gateway search unit 43 that can find the HS gateway 40 to which it is connected.

In addition, a system map setting unit 44 for constructing a system map by using the information obtained through the host configuration information receiver 42 and the gateway gateway search unit 43 is provided.

This configuration allows for interprocessor communication (IPC) transmission between HS and RS to be maintained in any variable situation.

In the present invention, the gateway (G / W) device can be used without distinguishing between HS and RS.

However, at the time of initial reset, it determines whether its current position is HS or RS based on the system ID determined by the back board, and recognizes its slot ID. Then, the gateway (G / W) device performs each operation according to the HS and RS.

Fig. 8 is a block diagram showing an example of setting a map by changing shape information according to the application of the present invention.

Thus, as shown in FIG. 8, the HS gateway G / W receives information about the RS to be connected thereto from the HS main processor 30. The received information is shown in the table of FIG.

The example in FIG. 6 is a destination RS with respect to a port number, as follows.

-Port # 0: RS # 3

-Port # 1: RS # 15

-Port # 2: RS # 7

-Port # 3: RS # 11

Thus, system shape information reception is performed at initial startup or system configuration change, and the HS gateway (HOST G / W) changes the system map managed by itself after the information reception. After receiving data transferred from the HS main processor (HOST MP) to the RS main processor (RS MP), the HS gateway (G / W) reads the destination address of the corresponding data, and the system is configured in the currently configured system map. Therefore, it transmits to the corresponding port.

In addition, a response to a search signal transmitted from the RS gateway G / W or a response to a path status check signal is performed.

Since only the HS main processor (HOST MP) knows the system configuration information, the RS gateway (G / W) cannot obtain that information before HS and RS are connected, and due to the difference in actual system capacity, Since only one port is used for / W), no port configuration is required. However, a problem arises in that the HS gateway (G / W) connected to itself when operating in a variable shape cannot be known in advance.

In order to solve this problem, the RS gateway G / W repeatedly polls transmission of a predetermined scan signal to each HS gateway G / W at an initial reset. When the HS gateway (G / W), which is aware of the RS connected to it by the dual system map, responds to the search signal, the RS gateway (G / W) matches the gateway (G / W) that gave the response. It is registered as a gateway (G / W).

As a result, both the HS gateway and the RS gateway set route information according to the system configuration.

As described above, the present invention detects the gateway gateway itself which is not yet defined due to the variable shape application between one host system and a plurality of remote systems connected through two or more gateways, and establishes a communication path. It is a variable connection between a number of remote systems.

Although the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. Accordingly, the above description does not limit the scope of the invention as defined by the limitations of the following claims.

As described above, an apparatus and method for automatically setting a data path in an access gateway according to the present invention are still defined due to the variable shape application between one host system and a plurality of remote systems connected through two or more gateways. It is effective to find out the gateway of itself not established and establish the communication path, so that it can variably connect the internal system and the multiple remote systems.

In addition, the present invention enables a flexible system configuration, unlike the prior art, and can reduce the port that can not be wasted when operating in a fixed shape, it is possible to expect a cost reduction effect.
