The present invention relates to a technology for checking a call path in a service server in a mobile communication system. More particularly, the present invention relates to a technique for checking whether a call path is well set so that a message or a call can reach a destination, The routing path is automatically checked from the originating service server to the final destination service server on the basis of the prefix using the routing information and the route sequence information to detect whether looping or routing errors And more particularly to an apparatus and method for detecting a call path error in a mobile communication system suitable for use in a mobile communication system.

2. Description of the Related Art Generally, a service server in a mobile communication system is a mobile switching center (MSC), which is a mobile switching center (MSC), for processing origination and reception requests from mobile communication terminals included in each base station, Performs network interworking, and performs inquiry about a subscriber of a mobile communication terminal with a home location register (HLR).

If the subscriber is confirmed through the inquiry about the subscriber, the originating service server requests the call from the origination request mobile communication terminal to the final destination service server including the mobile communication terminal desiring to receive the call, and the final destination service server When a call is requested by requesting a call to a called mobile communication terminal through a base station, the call between the calling mobile communication terminal and the called mobile communication terminal is connected and the call between the mobile communication terminals is performed do.

In the service server, the call path means a route that is a set of trunk lines connected between the service server and the service server, and thus routing in the service server means routing in a call to another service server.

If the routing is wrong, the call connection may not be established, and connection delays and incorrect call connection may occur.

A method of checking whether a conventional call path is well set and detecting an error is to determine whether an operation is abnormal by registering a new station number with a service server and calling a test number directly to confirm whether or not the connection is established It is judged whether there is an abnormality from the originating service server to the final destination service server.

However, the call path is not composed of a single path but is divided into several routes in consideration of the amount of calls, or configured as a bypass path for connection in case of failure. That is, at least one of a single path, a call distribution path, and a bypass path.

In the method of checking the call path in the service server according to the related art operating as described above, the operator registers the new station number in the service server and calls the test number directly to confirm whether or not the connection is established. Therefore, there is a problem that the test can not be performed on the bypass path in case of failure. In case of the call distribution path, even if the call connection is made through the test, all normal operation paths I was not able to confirm that there was no problem.

Here, the call path error detection apparatus 100 may be included in the service server or may be associated with the service server as a component in the mobile communication system.

Specifically, the data collection unit 102 collects at least one of a prefix, a route, a special sequence, and a route sequence in the service server, and stores the collected information in a DB It is the role of

The configuration information collected here will be described in detail below.

The dictionary meaning of a prefix is defined as "A Telephone Office Number", "precedent", and "office". The prefix in the mobile switching network includes an international telephone number, a public switched telephone network (PSTN) relay number, that is, a local number (for example, 02, 0342, , A number capable of identifying a registered service server, an emergency telephone number, a number capable of distinguishing a special service type provided to a subscriber, an additional service (for example, a call transfer, a call park, Call, etc.) registration, cancellation number, etc.

A route is a transmission line connecting two service servers, and a group of a plurality of trunks is a route. That is, a set of trunks connected between two service servers can be defined as a root.

The Special Sequence is implemented for the purpose of outgoing call processing by distributing a call to a plurality of root sequences in a specific time period or a specific rate or a combination of time and rate according to the call distribution method.

Route Sequence consists of a set of multiple routes. One root sequence consists of one direct route (DR) and eight or less alternate routes (AR). The direct route is the route that is preferentially selected to occupy the trunk line in the case of the routing request, and the bypass route (AR1 to AR8) is the route for the second to third trunk to the 9th trunk line occupancy request when the trunk occupancy in the direct route fails.

The call path generation unit 104 creates routing information on a system-by-system basis using the configuration information data collected from the data collection unit 102 and connects the information to the end-to- End Create the path.

That is, a call route of a direct route or a bypass route connected to a source service server on the basis of a prefix is connected to each service server unit to generate all call paths that can be connected to the final destination service server.

The error detection unit 106 analyzes all the call paths in the end-to-end path generated by the call path generation unit 104, and if there is a call that does not reach the final destination service server in the middle, If an error occurs, it is displayed on the end-to-end path map.

That is, when no further path movement occurs in a specific service server, it is indicated as a path not set error, and if a call is repeatedly moved more than a predetermined number of times within a specific number of service servers, have. In addition, if the gateway server goes to the final destination service server through a plurality of gateway service servers more than necessary, the network resources are wasted and it may be indicated as an error.

The detection result inquiry unit 108 outputs the final call path detection result to the predetermined application when the error analysis for each call path is completed from the error detection unit 106, and provides the function that operators can easily check.

Here, the application can be generally represented in the form of a web page on the Internet, and the call path for each system unit is displayed in a tree structure, and the detected error is displayed in a different color such as red so that the operator can grasp the error at a glance Can be implemented.

2, in step 200, the data collecting unit 102 in the call path error detecting apparatus 100 determines a call path from a specific service server, that is, an originating service server to an end destination service server at the end, It performs status check on all call paths such as route, call distribution route, bypass route, etc., and collects configuration information data for each call path to DB.

In step 202, the call path generation unit 104 generates a routing map on a system-by-system basis using the collected configuration information data, connects the routing map information generated in step 204, and transmits the routing information from the originating service server to the final destination service server, -to-End Generate a path map.

In step 206, the error detection unit 106 analyzes the end-to-end path maps generated through the call path generation unit 104 to determine whether there is an error on the path. If an error occurs, Display it in the path map.

In step 208, the detection result inquiry unit 108 outputs the final call path detection result to the predetermined application when the error analysis for each call path is completed, so that the operator can easily confirm the result.

3 is a diagram illustrating a data collection method according to an embodiment of the present invention.

3, the data collecting unit 102 collects configuration information data (prefix, route, special sequence, root sequence information, and the like) from the service servers 300 of all call paths from the originating service server to the final destination service server, And collects configuration information data by distributing a predetermined number of service servers through a distributed collection server, that is, a plurality of distributed collection servers 302, in order to collect data smoothly from a plurality of service servers Thereafter, the collected configuration information data are all stored in the configuration management unit 304, which is a central DB server.

The configuration management unit 304 may be included in the data collection unit 102. If the data collection unit 102 is separated from the configuration management unit 304, When the call path configuration information data is requested, the configuration management unit 304 collects the configuration information data of the call path and transmits the configuration information data to the data collection unit 102.

4 is a diagram illustrating a call path generation process in a call path generation unit according to an embodiment of the present invention.

Referring to FIG. 4, the call path generation process in the call path generation unit 104 will be described in detail. First, as the sequence type information based on the prefix information 400 of the service server, special sequence information 402, Information 404, route information 406, and the like.

When the sequence type is the root sequence, the service route to the service server is determined by referring to the value of the direct route. In the route gateway service server, the next route service server is determined through the same step, . This is the same way as the bypass route.

If the sequence type is a special sequence, the route to the final destination is searched for by the call distribution route distributed by the plurality of route sequences, and the route search method is performed in the same manner as the route sequence method.

Routing information in each service server is generated by the system unit routing information 408. The generated routing information is used to connect the generated system unit routing information 408, 410, 412, and 414 for each service server, End-to-end path map 416 to the final destination service server.

5 is a diagram illustrating a call path generation method in a call path generation unit according to an embodiment of the present invention.

5, the prefix information 400, the special sequence information 402, the root sequence 404, and the route information 406 are collected on the basis of the prefix in the originating service server and are DB, As a result, the systematic routing map 408 is generated.

6 is a diagram illustrating a case of a call path loop occurrence in an error detection unit according to an embodiment of the present invention.

Referring to FIG. 6, in the case of a loop occurrence, for example, a service server A is set to go to a service server B by a prefix 111, And the server is set to go to the A service server with respect to the 111 prefix.

This means that the prefix 0023 started in the service server # 1 600 is transmitted to the terminal RTE 612 via the gateway service server # 1 602, the gateway service server # 2 604 and the gateway service server # When a failure occurs in the direct route of the gateway service server # 3 (606), the route is returned to the bypass route connected to the gateway service server # 4 (608) and the gateway service server # 5 (610) do. However, if the gateway service server # 5 610 on the detour route erroneously sets the route of the prefix 0023 to go to the gateway service server # 3 606 without going to the terminal RTE 612, The prefix 0023 initiated from the gateway service server # 3 606, the gateway service server # 4 608, and the gateway service server # 5 610 are continuously looped.

7 is a diagram showing a case where a call path route is not registered in the error detection unit according to the embodiment of the present invention.

Referring to FIG. 7, there is a case of a route mismatch due to an information registration error. If the prefix is not registered in the specific exchange or the route is not registered in the prefix, the call connection is terminated if the prefix is missing. If the route is not directly registered in the specific exchange, the bypass route If you try to connect but both are disconnected, the call connection ends.

That is, the prefix 0023 started from the service server # 1 700 is directly routed from the gateway service server # 1 602 to the gateway service server # 4 708, from the gateway service server # 4 708 to the gateway service server # Via the detour route of the service server # 1 700 to the terminating RTE 712 or via the detour route to the gateway server # 2 704 via the detour route, The gateway service server # 2 704 is routed through the gateway service server # 3 706 directly to the root RTE 712.

In this case, when the gateway service server # 4 (708) passes directly through the gateway service server # 5 (710) as a route, the route or bypass route is not set directly in the gateway service server # 5 (710) Even if the service server # 5 710 attempts to connect to each route, the call connection is terminated as an unset route.

If the call connection is not established as shown in FIG. 6 and FIG. 7, it can be detected as a call path error. In addition, when the number of HOPs is exceeded, the number of HOPs passes through several gateway service servers To the final destination service server. In this case, there is no problem in the call connection, but since the network resources are used more than necessary, the number of the maximum number of relay service servers relative to the network resource is set from the originating service server to the final destination service server, And if the call path is set to the final destination service server, it is determined as a call path error.

8 is a diagram illustrating a call path inquiry method through a detection result inquiry unit according to an embodiment of the present invention.

8, the detection result inquiry unit 108 in the call path error detection apparatus 100 includes an originating service server recognition number input unit interlocked with the call path error detection apparatus 100, a prefix input unit, Unit-based routing information 802 for providing service server information of a direct route and a bypass route interlocked with an originating service server, an input unit 800 including an excel storage unit for storing the result of the excel- And an end-to-end path unit 804 for generating an end-to-end path map in a tree structure on the basis of each system unit routing information, and the like.

For example, as shown in FIG. 8, two detour routes of the MSC 1xx indicate that a loop 806 has occurred in one CGSxx. In the other CGSxx, there is one unconfigured route information 808, and in the other CGSxx (810) connected to the final destination service server via seven systems exceeding a preset number of routes (for example, 6) among the connected call paths.

Accordingly, the end-to-end path unit 804 can grasp the connection state of the system-unit routing information as a tree structure at a glance.

That is, the loop 806 generated in the CGSxx, which is the bypass route of the MSC 1xx, is known as the loop generated in the CGS99 812, and the state of the path not set 814 generated in the other CGSxx as the bypass route of the MSC 1xx . Further, the excess call path information 810 is displayed in a different color together with the record that the other CGSxx has passed through [07] KT-HH seven times, so that it can be grasped easily.

In this way, the application of the detection result inquiry unit 108 can be displayed in the form of a web page through the web, and the call paths of each system unit are displayed in a tree structure, and the detected errors are displayed in red, And the like.

In addition, only an error part detected through the mobile communication network is provided to the mobile communication terminal of the operator in the form of a text message, so that a quick error check can be made possible.

As described above, according to the present invention, it is possible to determine whether a call path is well set so that a message or a call can reach a destination in a mobile communication network using a prefix, a route, and a root sequence information of each service server, To the final destination service server, and detects whether looping or routing errors occur.

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments, but is capable of various modifications within the scope of the invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the scope of the appended claims, and equivalents thereof.
