In other words, with the advent of the high information age, it is necessary to establish ISDN that can provide users with more economical and high-quality services, and various voice and non-voice services. As the channel (CAS: Channel Associated Signaling) method, it is difficult to transfer various comprehensive information, thereby introducing the No. 7 signal system, which is common channel signaling (CCS). Here, in the above-described No. 7 signaling system, it is inevitable to interwork with an ISDN user part (ISUP, ISDN), which is responsible for signaling functions such as line connection control, line monitoring control, and additional service control related to line connection.

As described above, the No. 7 signaling method needs to confirm the reliability of the communication path at the time of call setup in order to ensure the reliability of the communication line at the time of call setup and the quality state on the transmission path. However, in implementing No.7 signaling, there is no proper way to determine the situation except for a direct message such as a signal point down when a failure or a problem occurs in an exchange (MSC), a home location register (HLR), or the like. .

(Example)

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

1 is a schematic block diagram of a system for determining a fault location of a switching network according to an exemplary embodiment of the present invention.

As shown in FIG. 1, the system includes a plurality of exchangers 100_1 to 100_n located inside a specific mobile communication provider network; A fault information collection server 200 for receiving and storing a failure message (Trunk Seizure Fault) according to the initial call setup failure from the plurality of exchanges (100_1 to 100_n); And an operator terminal 300 for checking contents stored in the failure information collecting server 200.

Each switch 100_1 to 100n is located at a corresponding location within the specific mobile communication provider network, and transmits an initial message (IAM, Initial Address Message) for confirming the switching network to a destination exchange (MSC, not shown). If a response message (ACM, Address Complete Message) for the transmitted initial message is not received from the called party exchange, the Trunk Seizure Fault is generated accordingly. Here, look at the message format of the failure message as follows.

[Message Format]

"MSC # 107 2005-06-01 00:02:27 Wednesday

F6210 TRUNK SEIZURE FAULT

LOC: ASS08 / ASPP2 / LNK010 / CH19

INF: RTE = 801 TRK = 2323 TYPE = OGT_ISUP

SEND_DGT = 1932777220

DPC = H'2484

CIC = 0147Z

REASON = ACM_NOT_ARRIVED

COMPLELTE "

For reference, the format information indicates a case in which a specific subscriber attempts to make a call from the switch (MSC # 107) to a called party, that is, '1932777220', but fails due to an outgoing call that fails to establish a normal call. The 'SEND_DGT' is the called party's telephone number that the calling subscriber has attempted, and the '1932777220' indicates a specific exchange, for example, 'MSC # 137'. In other words, the format of the format indicates that the particular subscriber has designated 'MSC # 107'. Attempted to call 'MSC # 137' through the call, but the call setup is not completed normally.

The failure information collection server 200 receives and stores a failure message (Trunk Seizure Fault) generated when the exchange network check for initial call establishment with the destination exchange fails from each of the exchanges 100_1 to 100_n. Base 210; And an information collection unit for collecting routing information of the called exchange in accordance with a predetermined period from the failure message stored in the database 210, counting the number of occurrences of the collected routing information to the operator terminal 300. 220; has a configuration that includes. Here, the information collecting unit 220 collects the routing information including the telephone number information (Send Digit) of the called party according to the predetermined period from the failure message stored in the database 210, and the collection The number of times of duplicated phone number information is counted. That is, the information collecting unit 220, for example, only collects the upper 5 digits (Digit) or 6 digits (Digit) including the station number data (PFX) information from the telephone number information of the called party included in the failure message, By counting the number of duplicated station number data, and storing the counted number of duplicated station number data on the database 210, it is possible to read through the operator terminal (300).

The operator terminal 300 displays a duplicate number of station number data counted by the failure information collection server 200 to a system operator, thereby allowing a system operator to determine whether a specific exchange or home location register (HLR) has failed. do. That is, if the number of times of duplication of the specific station number data PFX occurs more than a predetermined threshold value, the system operator who reads it through the operator terminal 300 recognizes that a failure occurs in an exchange or a home location register in which the station number data is received. Routing, that is, call connection paths can be changed.

Hereinafter, with reference to FIG. 2, a failure location determination method in a switching network according to an embodiment of the present invention will be described. 2 is a flowchart illustrating a fault location determining method of a switching network according to an exemplary embodiment of the present invention.

First, all of the switches 100_1 to 100_n in a specific mobile communication provider network transmit an initial message (IAM) for call setup to a called side exchange (not shown) (S110).

Next, when each of the exchanges 100_1 to 100_n does not receive the response message ACM for the initial message IAM from the destination side exchange, a corresponding Trunk Seizure Fault is generated (S120).

Thereafter, the information collection server 200 collects and stores the failure message generated from each of the switches 100_1 to 100_n (S130). That is, the information collection server 200 receives a failure message generated when the initial call setup with the destination side exchange fails and stores it in the database 210.

Then, the information collection server 200 collects routing information of the destination side exchange from the failed message stored at predetermined intervals (S140). That is, the information collection server 200, the top 5 that includes the station number data (PFX) of the telephone number information (Send Digit) of the called party from the failure message stored in the database 210 through the information collection unit 220 Collect Digits or Digits.

Then, the information collection server 200 counts and stores the number of times the overlapping occurrence of the collected routing information is stored (S150). That is, the information collecting server 200 counts the number of times of duplication of the station number data PFX information through the information collecting unit 220 and stores the counted information in the database 210.

Finally, the operator terminal 300 accesses the information collection server 200 to view the number of occurrences of the duplicated routing information stored therein to determine the location of the specific exchange or home location register in which the failure occurs (S160). That is, if the number of times of duplication of the specific station number data PFX occurs more than a predetermined threshold value, the system operator who reads it through the operator terminal 300 recognizes that a failure occurs in an exchange or a home location register in which the station number data is received. The call connection path is changed. For example, if the duplicate number of the station number of the station number data '02 -111-**** 'stored in the information collection server is relatively higher than that of other station numbers, the system operator has a problem with the' KT 'exchange housed with the station number. Determine and change the call connection path. In addition, when the number of overlapping station numbers with mobile communication terminal numbers is relatively higher than other station numbers, such as' 016-99 **-****, the system operator has a failure in the mobile communication operator side operating the station number. Recognizing that it has been done, you can request the mobile operator to take action on the home location register that accommodates the station number.

As can be seen from above, the system and method for determining the fault location of the switching network according to the present invention analyzes the fault message of the ISUP protocol, thereby causing the system operator to fail the specific switch or the home location register (HLR). By quickly recognizing whether or not, the quick action is possible before the failure of the company's exchange is widened.

In addition, the present invention is possible to continue the service for the switching subscriber (Churn-in) by changing the call setup path in case of failure of the other party switching network.
