Call Processing System and Mobile Signal Network and Voice Signal Incoming Routing Method

The present invention relates to a call processing system in a mobile telephone network and a method for setting a voice signal incoming route, and more particularly, when a voice call is received from a caller's other telephone network to a called party's mobile telephone network, using a source telephone network from the caller to the called party. The present invention relates to a voice signal incoming path setting method for setting a path up to.

Conventionally, when attempting to make a call from the caller's other telephone network to the called party's mobile telephone network, the mobile telephone exchange service serves the area where the called party is located via the telephone network relay switch (TS) to which the caller belongs and its neighboring mobile telephone network relay switch. A call path has been established.

However, due to the amendment of the relevant law on the settlement of charges between operators, charges are settled according to the number of hops of the exchanges passed through the company's network and other carrier's networks. There is no big disadvantage because the route is set to the mobile telephone relay switch in the neighboring area by using the local network through the area code of the wired telephone network according to the route setting method. Because we do not know, we are in a very unfavorable position with respect to routing.

Meanwhile, in order to solve the problem, there is a method of notifying the calling party of the location of the called party when the incoming call is set up, which causes various difficulties such as protecting the company's network system and protecting the subscriber's information. There was a problem.

Accordingly, the present invention has been made to solve the above-mentioned problems, and other telephone network operators (wired, mobile telephone networks) that need to set up an incoming call as a mobile telephone subscriber have a mobile telephone network for other purposes such as resources, revenue, and services. The caller can make the best use of the source telephone network from the calling party to the called party so that the mobile telephone network operator can access the network from other telephone networks while securing the stability of the network, subscriber information, and the security of the company's service when the call is requested. Its purpose is to provide a method for establishing a route to the recipient relay switch of the closest In Geun.

Hereinafter, an operation process of an embodiment according to the present invention will be described with reference to the accompanying drawings.

1 is a view showing the overall configuration of a call processing system according to an embodiment for applying the present invention.

Referring to FIG. 1, a call processing system includes a home location register (HLR, 400), a common gateway (CGS, 600), a destination exchange (MSC, 500), a gateway (GW, 200), and a fixed point in a network. It includes a gateway home location register (GHLR) 300 including a database function and a gate function in a network that manages subscriber level information, location information, etc. for providing a service.

The HLR 400 includes a function for recognizing the GHLR 300, a call request call includes a basic call or other call discrimination function, and a double call discrimination function is performed when the subscriber state is idle and additional services. Is determined as a basic call when the service is inactive, and as other calls when the subscriber status is not idle, when the called party service is activated, or when roaming on the 3G network.

Hereinafter, an operation process according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

First, a home location register (HLR) accepting a called party subscriber when receiving a query message including a number to be called in order to attempt a call from the caller's exchange through the other telephone network to the called party's mobile telephone network. When the query is made, it is determined whether the requested call is a basic call or other call.

In this case, the call can be actually received by the subscriber's TLDN, and if the TL is the receiver's own network, the call is judged as a basic call, and if the additional service is activated or the receiver's TLDN cannot be received, the call is sent to the 3G network. When the roaming or the FP is operated, if it is determined as a guitar arc, each operation flow according to the determination will be described with reference to the accompanying drawings.

2 is an exemplary view showing an operation flow for basic call processing according to the present invention. As shown in FIG. 2, a number to be called to try to make a call from the caller's switch 100 to the called party's mobile telephone network through another telephone network is shown. When receiving the query message including the gateway home location register (GHLR, 300) (S100), the digits (dial-dialed) is analyzed to find the HLR that accommodates the corresponding station number, the location request request message including the digit value to the found HLR (LOC [Digits]) is transmitted (S101). At this time, the subsystem number (SSN) of the gateway home location register (GHLR) is set to 8 (MSC).

When the HLR 400 receives the location request request message (LOC [Digits]), the location request signal point recognizes a system for performing a gate function. A routing request message (RTR [MIN]) for obtaining a TLDN is output to the destination exchange (MSC) 500 (S103).

When the MSC 500 transmits the TLDN according to the request of step S103 and transmits the TLDN to the HLR 400, the MSC 500 includes the TLDN in the location request return result message and transmits the TLDN to the GHLR 300 (S104 to S105).

The GHLR 300 transmits the received TLDN to the caller switch 100 of another telephone network (S106).

Figure 3 is an exemplary view showing the operation flow for other call processing according to the present invention, as shown in the query message including a number to be called in order to attempt to make a call from the caller's switch through the other telephone network to the called party's mobile phone network When receiving (S200), the digits (digits-dialed) is analyzed to find the HLR accommodated by the corresponding station number, and transmits a location request request message (LOC [Digits]) including the digit value to the found HLR (S201).

The HLR 400 recognizes a system for performing the gate function of the requested signal point, and then, if the call corresponds to the other call by the call criterion, transfers the TL back to the GHLR 300. ) Together with the digits included in the location request is transmitted (S202).

The Roaming Area Code (RAC) value corresponding to the destination exchanger ID (MSCID) included in the message (loc [TL]) transmitted above is found, and the RAC and Dialed Digits are included in the location request return result message. When transmitting, call setup is performed by the mobile telephone network switch corresponding to the transmitted RAC or called number (S203).

If the above call cannot be handled as a basic call or other call, a method of handling an error by sending an announcement broadcast from the destination exchange office using a default roaming area code (Default RAC) value, and error and retransmission request (Reject) ) Use the method of handling the error at the sending station through forwarding.

In addition, Common Channel Signaling (CCS) No. 7, Sigtran (Signaling Transport) or MAP message is used to query the gateway home location register (GHLR) of the receiver from the originator exchange. Use a LocationRequest message, a Short Message Request (SMSrequest) message, or a separately defined message.

Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art will be able to variously modify and change the present invention without departing from the spirit and scope of the invention as set forth in the claims below. It will be appreciated.
