At this time, the mobile communication switch (120, 130) performs a home location register (121, 131: Home Location Register) responsible for providing all the information of the subscriber to the mobile communication switch (120, 130), and the mobility control logic for location registration It is connected to the VLR (122,132: Visitor Location Register).

The base station 112 is a device for performing a radio access function with the mobile station 111 and performs radio communication with the mobile station 111. And, the base station controller 113 is a plurality of base stations (first base station, ⃛ (Nth base station), which is located between the base station 112 and the mobile communication exchange (120,130) to deliver a message to the mobile communication exchange (120,130) or to receive a message from the mobile communication exchange (120,130), and Performs message transmission and reception with the base station.

In such a mobile communication system, since the base station 112 and the base station controller 113 are expensive to construct for each unit, in recent years, the base station and the base station controller are shared between each mobile communication service provider (Hansol, Freetel, etc.). The movement to be made is becoming visible. However, even in this case, the mobile communication exchangers 120 and 130 of each mobile communication provider are separately provided to provide their own services.

On the other hand, from the viewpoint of service processing requested from any mobile subscriber, the service request made from the mobile station 111 currently in the area managed by the first base station controller 113 is applied to the base station 112 and the first base station controller. It passes through 113 to the first mobile communication exchange 120.

However, when the first mobile communication switch 120 is unable to perform the currently requested service, the service cannot be provided, thereby lowering the overall service completion rate of the mobile communication system, thereby reducing the service to the subscriber. There was a problem that the quality is lowered.

Accordingly, the present invention has been made to solve the above problems, in a mobile communication system in which a plurality of mobile communication providers that provide mobile communication services such as PCS service or cellular service share a base station and a base station controller, mobile communication An object of the present invention is to provide a method for establishing a path for providing a mobile communication service requested by a subscriber.

In order to achieve the above object, the service rerouting method in the mobile communication system according to the present invention requests a mobile communication service from one mobile communication subscriber to one of the mobile communication service providers through a mobile station. Becoming; Forwarding the attempted service request message to a predetermined first mobile communication exchange; The first mobile communication exchange providing the service if the requested service is available; otherwise, sending a predetermined service redirection message to the base station controller to reset the service path; Sending the service rerouting message to the mobile station, the mobile station re-requesting the mobile communication service for a predetermined other mobile communication provider; Forwarding the re-requested service request message to a predetermined second mobile communication exchange; And the second mobile communication exchange comprises performing the requested service.

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

2 is a flowchart illustrating a service rerouting method in a mobile communication system according to the present invention, in which a state of a corresponding mobile communication switch 120 to process a mobile communication service requested by a mobile subscriber is not sufficient to provide this service. In this case, a process of providing a service using the new mobile communication switch 130 at the request of the mobile communication system is shown.

First, a mobile communication subscriber located in an area managed by the first base station controller 113 requests a predetermined mobile communication service such as an outgoing signal setting request or a location update request through the corresponding mobile station 111 (step S21).

The service request message requested by the mobile station 111 is wirelessly transmitted to the corresponding base station 112, and the base station 112 also transmits the service request message to the first mobile communication exchanger through the first base station controller 113. 120) (step S22).

Receiving the service request message, the first mobile communication switch 120 determines whether it can currently provide the corresponding service (step S23), and if the service is available, performs the procedure of providing the corresponding service (step S24).

However, when the requested service cannot be provided, a service redirection message is sent to the first base station controller 113 to reset the service path (step S25).

The service rerouting message is a message indicating that the service is provided through the other mobile communication exchange because it is currently difficult to provide the service in the first mobile communication exchange 120.

The service rerouting message sent from the first mobile communication switchboard 120 is transmitted to the mobile station 111 through the first base station controller 113 and the first base station 112, and the mobile station 111 returns to another mobile communication provider. The service is requested (step S26).

The service request message regarding the service requested again by the mobile station 111 is transmitted to the predetermined second mobile communication exchange 130 of another mobile communication operator through the first base station 112 and the first base station controller 113 (step). S27)

Then, the second mobile communication exchange 130 receiving the service request performs the service requested by the mobile communication subscriber, so that the first service requested by the mobile communication subscriber is processed without being rejected (step S28).

Of course, if the second mobile communication exchange 130 cannot provide this service, the service request of the mobile subscriber will not be made in the end, but the likelihood of receiving the service increases.

Now, as an embodiment of the present invention shown in FIG. 2, a case in which the mobile communication subscriber requests the call setting is described.

First, a mobile communication subscriber located in an area managed by the first base station controller 113 attempts to set an outgoing signal through the corresponding mobile station 111 (step S21).

A predetermined call signal message about an originating call attempted by the mobile station 111 is transmitted to the base station 112, and the base station 112 also sends a first service request message for the attempted call signal to the first base station controller 113. It sends to the first mobile communication switch 120 via (step S22).

The first mobile communication switch 120 checks whether it is possible to provide the call setting service to the mobile station 111 that has requested the originating service (step S23), and if so, performs the call setting setting process (step S24). ).

However, when the call setting service is not available, a service redirection message for resetting the service path is sent to the first base station controller 113 (step S25).

The service path resetting message is a message for attempting to set up an outgoing signal through another mobile communication exchange because the outgoing call setting service is currently difficult in the first mobile communication exchange 120.

The first base station controller 113 transmits the service rerouting message sent from the first mobile communication switch 120 to the mobile station 111 through the base station 112, and the mobile station 111 makes an outgoing signal to another mobile communication provider. The setting is attempted (step S26).

Then, the re-requested outgoing signal is transmitted to the base station 112, and the base station 112 sends a predetermined service request message for the outgoing signal through the first base station controller 113 to the predetermined second mobile communication of another mobile communication provider. Transmit to exchange 130 (step S27).

The second mobile communication exchange 130 performs the calling signal setting service requested by the mobile communication subscriber, thereby processing the first call made by the mobile communication subscriber without being rejected (step S28).

Now, as another embodiment of the present invention shown in FIG. 2, the case where the mobile communication subscriber requests the location update will be described.

First, the mobile communication subscriber located in the area managed by the first base station controller 113 attempts to update the position of the mobile station 111 (step S21).

A Location Updating Request Message regarding the location update attempted by the mobile station 111 is transmitted to the base station 112, and the base station 112 also sends the received location update request message to the first base station controller 113. Is sent to the first mobile communication switch 120 (step S22).

The first mobile communication switch 120 checks whether it can perform a location update service at present (step S23), and performs a location update procedure if the service is available (step S24).

However, when the location update service is not available, a service redirection message for resetting the service path is sent to the first base station controller 113 (step S25).

The first base station controller 113 transmits the service rerouting message sent from the first mobile communication switch 120 to the mobile station 111 through the base station 112, and the mobile station 111 updates the location with respect to other mobile communication providers. (Step S26).

Then, the re-requested location update request message is transmitted to the base station 112, and the base station 112 transmits the location update request message to the second mobile communication switch of another mobile communication operator through the first base station controller 113. Transfer to 130 (step S27).

Finally, the second mobile switching center 130 performs the location update service requested by the mobile subscriber, thereby performing the location update service requested by the mobile subscriber (step S28).

As described above, the present invention can co-process mobile communication services among certain mobile operators, thereby increasing the overall service completion rate of the mobile communication system, thereby providing more improved services to customers. It can be effective.
