Hereinafter, the operation of each component of the toll service system during a call will be described in detail with reference to FIG. 1.

First, the mobile station (MS) 100 is a user interface device, which moves beyond the location registration boundary in the idle state, or when the preset location registration time elapses, the MSC 106 transmits its own information to the MSC 106. The location registration information is transmitted to update and store its location registration information in the VLR (Visitor Location Register) connected to the MSC 106.

A base transceiver station (BTS) 102 is a device configured as a radio transceiver and transmits / receives voice calls and packet data through a wireless link with a mobile communication terminal 100 in a radio access network (RAN). . A base station controller (BSC) 104 manages a plurality of BTSs 102 and is responsible for radio channel setup, frequency hopping, and handover processing.

The Mobile Switching Center (MSC) 106 is responsible for mobility management, location registration / management, authentication, handover, roaming, etc. of the mobile communication terminal 100. That is, when an incoming request from the mobile communication terminal 100 is received through the base station 102, an outgoing signal is transmitted to the called party of the called party, and if there is a response from the other terminal to the incoming signal, the channel is received. By assigning to form a communication path between the mobile communication terminal (200). In addition, the MSC 106 updates and stores the location registration information of the mobile communication terminals in each base station through the VLR, and manages the location registration information of the corresponding terminal implemented in the No. 7 network. The location information of the mobile communication terminal is periodically updated by transmitting it to a home location register (HLR) 108.

In addition, when executing the toll charging service during a call according to an embodiment of the present invention, the calling party mobile switching center (MSC) 206 transmits / receives an ISUP signal to the called mobile terminal switching center (MSC) 106 according to a call request from the calling terminal. Set up a call path between terminals according to reception.

The called party's mobile switching station 106 establishes a call path between the calling terminal 200 and the called terminal 100 in response to a call request from the calling mobile terminal 206, and is in a call between the called / calling terminals. If there is a toll charging request from the called party's terminal user, inform the HLR 108, and then send a toll charging setup message responded from the HLR 108 to the originating mobile switching center (MSC) 206. Toll charging of the called terminal 100 for the call is performed.

The HLR 108 is a database center that manages the status of mobile subscribers, statistics, and various service related information, including current location information of a mobile communication terminal, and also calls from the called-party mobile switching center 106 according to an embodiment of the present invention. If the toll charge request is received, the toll-bearing setup message for the call between the incoming and outgoing terminals is generated and transmitted to the calling party switching center 206 through the called party switching center 106, the billing service center. In step 208, charging to the called terminal 100 for the call is performed.

2 is a flowchart illustrating an operation control flow for toll charging service during a call in a mobile communication network according to an exemplary embodiment of the present invention. Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

First, when the calling party mobile station 206 receives a call request from the calling party terminal 200 to the called party terminal 100, the calling party mobile station 206 sets a call to the corresponding called party mobile switching station 206 of the called party terminal 100. An ISUP_IAM (Initial Address Message) is transmitted (S200).

Then, when the state of the called terminal 100 is idle, the called party mobile switching station 106 transmits an ISUP_ACM (Address Complete Message) to the calling mobile switching station 206 in response to the ISUP_IAM. If the called party terminal 100 responds to the incoming call (S202), the called-party mobile switching center 106 transmits an ISUP_ANM (Answer Message) to the calling-party mobile switching station 206 (S204). Accordingly, a call path is formed between the calling terminal 200 and the called terminal 100 to perform a call.

At this time, when the called terminal user wants to pay the call charges toll free while performing the above call according to the present invention, the called terminal user inputs a predetermined specific key or FC (Feature Code: Additional Service Control Code) ) To request toll charges for the call.

That is, when there is a toll charge request key input from the called terminal user as described above, the called party mobile switching center 106 sends a toll charge request for the call to the HLR 108 in a MAP_Feature Request message to charge the toll charge. The request is transmitted (S206).

Then, the HLR 108 checks the information of the called / calling terminal (100,200) according to the toll charge request, and sets the MAP_Feature Request Return message to set the charge for the call to the called terminal (100). In response to the request message, the message is transmitted to the called-party mobile switching center 106 (S208).

Then, the destination mobile switching station 106 transmits to the calling mobile switching center 206 including the toll charge setting information included in the MAP_Feature Request Return message received from the HLR 108 in the ISUP_CPG or ISUP_UUI signal (S210). . Accordingly, the calling party mobile switching station 206 analyzes the toll charge setting information in the ISUP_CPG message transmitted from the called mobile switching center 106, and sends the calling terminal 200 and the called terminal (the charging service center 208). Toll charge data (CDR) for the call between 100) is transmitted so that the caller is charged for the call.

3 is a flowchart illustrating an operation control flow of toll charge billing service during a call when a call is made with a called terminal on which an incoming call is set in a mobile communication network according to another embodiment of the present invention. Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. 3.

ISUP_IAM (Initial Address Message) is transmitted (S300).

Then, when the state of the called terminal is idle, the called party's mobile station # 1 402 transmits an ISUP_ACM (Address Complete Message) to the calling mobile station 400 in response to the ISUP_IAM. An incoming call is attempted (S302). At this time, if the incoming call to the called terminal cannot be received, if the user has set up the call forwarding to another number, the called party mobile switching station # 1 402 transmits a MAP_Transfer to Number Request message to the HLR # 1 406. To request the call forwarding phone number set by the called terminal user (S304).

Accordingly, HLR # 1 (406) checks the call forwarding phone number set in the called party's terminal according to the call forwarding phone number request received from the called party's mobile switching center # 1 (402), and MAP_Transfer including the call forwarding phone number. to Number Return message is transmitted to the destination mobile switching center # 1 (402) in response to the MAP_Transfer to Number Request message (S306).

The called party's mobile switching center # 1 402 then sends an ISUP_IAM (Initial Address Message) for establishing a call from the calling mobile switching station 400 to the call forwarding telephone number. In step 308, transmission is made to (404).

Then, when the state of the called terminal is idle, the called party's mobile station # 2 404 transmits an ISUP_ACM (Address Complete Message) to the calling mobile station 400 in response to the ISUP_IAM. (S310). Subsequently, when the called terminal responds to the incoming call, the called mobile switching center # 2 404 transmits an ISUP_ANM (Answer Message) to the calling mobile switching center 400 (S312). As a result, a call path between the calling terminal and the called terminal is formed to perform a call.

At this time, when the called terminal user wants to pay the call charges toll free while performing the above call according to the present invention, the called terminal user inputs a predetermined specific key or FC (Feature Code: Additional Service Control Code) ) To request toll charges for the call.

That is, when there is a toll charge request key input from the called terminal user as described above, the called mobile switching center # 2 404 sends a toll charge request for the call to the HLR # 2 408 as a MAP_Feature Request message. To transmit the charge-sharing request (S314).

HLR # 2 (408) then checks the information of the called / calling terminal according to the toll charge request, and sets a MAP_Feature Request Return message for setting the charge for the call to the called terminal for the MAP_Feature Request message. A response message is transmitted to the called party's mobile switching center # 2 (404) (S316).

The called party's mobile switching center # 2 404 then transmits to the calling mobile switching center 400 including the toll-bearing setting information included in the MAP_Feature Request Return message received from the HLR # 2 408 in the ISUP_CPG or ISUP_UUI signal. (S318).

At this time, the called party's mobile switching station # 2 404 includes a phone number of the called mobile terminal when transmitting ISUP_ANM, ISUP_CPG or ISUP_UUI to inform the calling mobile terminal 400 of the called mobile terminal.

Accordingly, the calling party mobile station 400 analyzes the toll charge setting information in the ISUP_CPG message transmitted from the called party mobile station # 2 404, and the receiver for the call between the calling party and the called party terminal to the charging service center. By sending the charge charge, the callee is charged for the call.

Meanwhile, in the above description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the invention should be determined by the claims rather than by the described embodiments.
