Description

Prepaid Call Routing Method in Mobile Communication System

The present invention relates to a prepaid call routing method for routing a prepaid call in a mobile communication system.

First, the prepaid service is to reduce the usage fee every time a mobile communication user pays a predetermined amount in advance, and is similar to a public telephone card of a landline telephone.

The biggest advantage of the prepaid service is that users who cannot receive the mobile communication service due to bad credit can use the mobile communication, and there is no fear of unpaid fees for the service providers and can reduce the fee storage cost.

In addition, it is accepted as a convenience to control the call volume in the case of a person using a short-term mobile phone lease.

Meanwhile, in Korea, a code division multiple access mobile communication system has been introduced, but many people still do not enjoy the benefits of mobile phones due to the burden of subscription fees and radio wave usage fees.

Therefore, by providing the prepaid service through a code division multiple access mobile communication system, more mobile phone demand can be created.

Conventional methods of providing prepaid service are largely classified into a method using a calling card mainly used in the United States and a subscriber identity module (SIM) card used in the pan-European digital mobile phone camp.

However, such prior art has not yet been disclosed to the general public, and there has been a continuous demand for the development of a method for providing a new prepaid service.

Accordingly, the present invention devised to meet the above-described needs, in order to provide a prepaid service, the call is first divided into a general call and a prepaid call, and in the case of a prepaid call, The present invention provides a prepaid call routing method in a mobile communication system that allows a mobile telephone exchange to prepaid a prepaid call and to make an online billing at a prepaid server. There is a purpose.

A method of the present invention for achieving the above object is a prepaid call routing method applied to a mobile communication system, wherein the mobile communication switch is configured to check whether an outgoing telephone number of a prepaid call received from a subscriber is effectively registered. Stage 1; A second step of displaying a prepaid call in a subscriber data field according to the result of the checking of the first step; A third step of adding the prepaid routing number to the called number and processing the incoming call to the prepaid server; And a fourth step of performing an incoming call to the original called number after checking the validity of the prefade number.

Hereinafter, a preferred embodiment according to the present invention will be described in detail with reference to FIGS. 1 and 2.

1 is a block diagram illustrating a configuration of a network providing a prefade service in a code division multiple access mobile communication system to which the present invention is applied.

As shown, the network providing the prepaid service receives a code division multiple access (CDMA) by receiving a prepaid call by dialing the subscriber 100 and the subscriber 100 requesting to provide the prepaid service. Access) The pre-fade call is input from the code division multiple access base station 110 and the code division multiple access base station 110, which output to the exchange 130 and transmit the output of the code division multiple access exchange 130 to the subscriber 100. When the calling telephone number is retrieved from the code division multiple access visitor location register (HLR) 140, the calling telephone number of the subscriber 100 is sent to the visitor location register (VLR) 140. If it is not there, check whether the current subscriber number is valid in the home location register 120 again, and add the pre-fade routing number to the called number. Checking the prepaid routing number of the incoming call from the code division multiple access exchanger 130 and the code division multiple access exchanger 130 output to the ellular gateway switch) 150, the call is received by the prepaid server 170. A mobile telephone interconnection exchange 150 for processing, a prepaid server 170 and a public network 160 which first check whether a prepaid number is valid for an incoming prepaid call and process the incoming call to the original called number if valid. have.

2 is a flowchart of a prepaid call routing method in a code division multiple access mobile communication system according to an embodiment of the present invention.

As shown in the figure, a method of routing a prepaid call is performed when the prepaid subscriber dials (210), and the code division multiple access exchange retrieves the outgoing telephone number received from the visitor location register (211). It is determined whether the incoming outgoing call number is registered in the visitor location register (212).

As a result of the determination, if it is not registered in the visitor location register, check whether the outgoing call number registered in the home location register is valid (213), and determine whether the outgoing call number registered in the home location register is valid (214), and outgoing call number If is not valid, after rejecting the incoming call (216), if the outgoing call number is valid, after displaying "Prepaid Call" in the subscriber data field (OriginationIndicator or CallingFeatureIndicator) (215), The result is notified to the access exchange (219).

On the other hand, if the incoming outgoing call number is registered in the visitor's location register, after confirming that the outgoing call number is valid (217), it is determined whether the outgoing call number is valid (218). Repeat from the process of checking whether the registered outgoing telephone number is valid (213), and if the outgoing telephone number is valid, after displaying " prepaid call " in the subscriber data field (215), the result is returned to the code division multiple access exchange. Notify (219).

Subsequently, if the PDM exchange determines that it is a "prepaid call" in the subscriber data field (OriginationIndicator or CallingFeatureIndicator) (220), it adds the prepaid routing number to the called number and transmits it to the mobile telephone interconnection exchange (221). ).

The mobile telephone interconnection exchange then checks the prepaid routing number of the incoming call and forwards it to the prepaid server (222).

Thereafter, the prefade server searches for whether the incoming prefade number is valid (223) and determines whether the prefade number is valid (224).

If it is determined that the result is invalid, the process terminates. If valid, the process terminates after receiving the incoming call to the original called number (225).

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited to the drawing.

The present invention as described above, by developing a method for routing the pre-paid call to the pre-fade server to perform the pre-fade service in the code division multiple access mobile telephone system while minimizing the change of the conventional code division multiple access network Provide fade mobile phone service and provide mobile communication service to more people by accommodating subscriber demand (customer who feels burden on initial mobile phone entry cost and short-term mobile phone use) that cannot be accommodated in conventional mobile phone service. It can work.
