Hereinafter, a communication service and an abnormal call collection process performed by such a mobile communication service system will be described with reference to FIGS. 1 to 3.

First, when a number such as a phone number is input through the calling terminal 101 and a call to the called terminal 161, 163, 165 occurs, the calling exchange 120 received through the wireless access network 110 receives the calling terminal 101. In order to determine whether or not to subscribe to the caller information display service of the subscriber to create a subscriber information request signal including a call signal and delivers to the calling home location register (130). Here, if the user of the originating terminal 101 is a malicious user generating a one-ring spam call, the originating apparatus 103 may be used for convenience. However, this is only an optional use for convenience and will be omitted in the following description.

Subsequently, the calling home location register 130 checks the profile information of the calling terminal 101 to determine whether it is subscribed to the caller information displaying service, and if so, creates a caller information displaying message to the caller information displaying server 140. Ask.

In addition, the caller information display server 140 creates a caller information display message including a caller information, a service activation tag, a text length tag, etc. preset by the caller and returns the message to the calling home location register 130.

Next, the originating home location register 130 transmits the caller information display message created by the caller information display server 140 to the originating exchange 120.

In addition, the originating exchange 120 requests routing information for routing the call to the called terminal 161, 163, and 165 from the called home location register (not shown), and the called home location register (not shown) receives the incoming call. Request the routing information to the exchange 150.

The destination exchange 150 then assigns routing information (i.e., the routing number that distinguishes the exchange) and returns this routing information to the destination home location register (not shown), and the destination home location register (not shown) The routing information is transmitted to the originating exchange 120.

Next, the originating exchange 120 requests a call connection with the called terminal 161, 163, and 165 based on the routing information received from the called home location register (not shown).

The destination exchange 150 transmits paging to the destination terminals 161, 163, and 165 through the wireless access network 115. At this time, the sender information display message is sent together with the paging.

Thus, the called terminal 161, 163, 165, the caller preset by the caller in the caller ID display area based on the caller information display message while notifying the occurrence of the incoming call through an alarm means such as a bell or vibration according to the reception of the paging. Display information.

When the termination signal is generated from the calling terminal 101 during the provision of such caller information display service (S301), the calling switch 120 terminates the call between the calling terminal 101 and the called terminal 161, 163, 165. .

The incomplete call generated by the originating terminal 101 is stored by the base station manager in the radio access network 110 in units of base stations.

Meanwhile, the incomplete call collecting unit 210 of the abnormal call collecting apparatus 200 collects incomplete call information stored in each base station by the base station manager in the wireless access network 110 (S303).

The arbitrary end call extracting unit 220 extracts an arbitrary end call within a preset time from among the incomplete calls collected by the incomplete call collecting unit 210. That is, in order to extract an arbitrary termination call that can be estimated as a one-ring spam call, a call terminated by the termination signal of the originating terminal 101 is extracted in a short time within a predetermined time (S305).

Next, the abnormal call determination unit 230 determines an abnormal call estimated as a one-ring spam call based on a result of comparing the number of times per unit time of the arbitrary termination call by the originating terminal 101 with a preset number. For example, if six or more arbitrary end calls are generated in one minute, the call generated by the originating terminal 101 is determined as an abnormal call estimated as a one-ring spam call (S307).

The abnormal call information stored in the abnormal call information storage unit 240 is managed.

In this way, by collecting, storing, and managing abnormal calls that can be estimated as one-ring spam calls, the operator can take action after finally determining and confirming spam calls through the collected information.

Although not shown in FIG. 2, the abnormal call collection apparatus 200 is controlled by the abnormal call determination unit 230 to display the information of the abnormal call stored in the abnormal call information storage unit 240 so as to be identified from the outside. It may further include. In this case, the operator can easily check the information of the abnormal call stored in the abnormal call information storage unit 240 through the call information display unit of the abnormal call collection device 200 without using a separate display device.

On the other hand, as described above, the abnormal call determination unit 230 may derive the determination result of the abnormal call and the normal call immediately according to the comparison result between the number of times per unit time and the preset number of times, but the subscription of the first determination result and the caller information display service. The abnormality call and the normal call may be distinguished by synthesizing the result of the second determination considering the state.

To this end, the caller information display server 140 may display information indicating whether the caller terminal displaying information of the caller terminal 101 is subscribed to and the caller information preset by the user of the caller terminal 101 of the abnormal call collection apparatus 200. The abnormal call determination unit 230 is provided.

The abnormal call determination unit 230 determines the abnormal call information only by subscribing to the abnormal call only when the subscriber is registered after checking the subscription status of the caller information display service even when it is determined as the abnormal call as the first determination result of step S307. The data storage unit 240 stores and manages the information in the storage unit S311 and S313. If it is determined to be an abnormal call as a result of the primary determination, it is recognized as a normal call and processed (S311 and S315).

Although the present invention has been described above with reference to embodiments, it is obvious that the technology of the present invention can be easily modified by those skilled in the art.

For example, in the above-described embodiment, an example of implementing an incomplete call storing means for storing an incomplete call generated by the originating terminal 101 as a base station manager in the wireless access network 110 has been described. It may be implemented to store at the originating exchange 120. In this case, the incomplete call collection unit 210 of the abnormal call collection device 200 collects incomplete call information stored by the originating exchange 120 as indicated by a dotted line in FIG. 1. If the abnormal call collection apparatus 200 according to the present invention is used in the wired communication service system, it is preferable to implement such that the exchange of the wired communication service system stores the information of the incomplete call as in the latter.

Such modified embodiments should be included in the technical spirit described in the claims of the present invention.
