Description
The present invention relates to a prepaid billing processing system and method for roaming overseas and a home location register for the same. More particularly, when a home location register receives a called terminal status inquiry request message from a home network exchange, the called terminal state is sent to a visited network exchange. If an inquiry message is sent and the home location register receives the called terminal status message from the visited network exchange, the called terminal is sent to the home network exchange if the called terminal is in a normal state based on the received terminal status message and the called terminal user is a prepaid billing subscriber. Prepaid billing processing system and method for transmitting a prepaid billing request message for a prepaid billing request message at a home network exchange, requesting prepaid billing for an incoming call to a service control device of a home network, and the same Relates to a home location register.
In general, a mobile communication system is a system that enables communication between mobile subscribers regardless of a subscriber's location by using space radio waves, and transmits and receives messages between a mobile communication terminal and a mobile communication terminal moving in an unspecified area. A base station that manages resources, a base station controller that controls and manages multiple base stations, and a switch that performs a switching role in conjunction with such a base station controller and other communication networks and performs an overall function according to call processing and data exchange of a mobile communication system. do. One of the most important features of such a mobile communication system is to ensure the mobility of the mobile communication terminal.
In addition, in the above mobile communication system, the billing process is generally charged to charge the calling terminal user. However, when the called terminal is roamed by being located in an overseas visited network, the billing process may be charged to the called terminal user. have.
On the other hand, one of the functions of the intelligent network has recently been provided a function to perform the prepaid billing process in real time. In general, the prepaid billing function allows a mobile communication terminal user to purchase a prepaid card in which a certain amount of currency limit is specified and perform a call as much as that amount. A mobile terminal user with a prepaid card can use the prepaid billing function in the same way as a normal call using his mobile terminal, and prepaid billing using a feature code to another mobile terminal. Function is available. In addition, the user of the mobile communication terminal may check his / her prepaid card balance and may charge the balance.
However, when the called terminal is located in the overseas visited network, the overseas visited network should be able to perform the intelligent network function in order to process the prepaid billing as described above. There is a problem that cannot be handled.
An object of the present invention is to receive the destination terminal status inquiry request message from the home network exchange transmits the destination terminal status inquiry message to the visited network exchange, the destination terminal is in a normal state based on the destination terminal status message received from the visited network exchange, If the terminating terminal user is a prepaid billing subscriber, a home location register for transmitting a prepaid billing request message for the incoming call to a home network exchange, and sends a terminating terminal status inquiry request message to a home location register, and processes the prepaid billing from a home location register. When the request message is received, the home network switch requesting the prepaid billing processing of the incoming call to the service control device of the home network, so that the destination terminal is located in the overseas visited network, even if the overseas visited network does not perform the intelligent network function. Prepaid billing through service control unit To provide a prepaid billing processing system and method for roaming abroad.
Another object of the present invention is a routing information providing unit for receiving a destination terminal status message by transmitting a destination terminal status inquiry message to a visited network exchange when receiving a destination terminal status inquiry request message from a home network exchange, based on the received terminal status message. Therefore, when the destination terminal is in a normal state and the destination terminal user is a prepaid billing subscriber, a home location register including a prepaid billing request unit for transmitting a prepaid billing request message for the incoming call to the home network exchange.
According to an aspect of the present invention to achieve the above objects, in the system for processing prepaid billing for incoming calls when roaming overseas, when the receiving terminal status inquiry request message from the home network exchange receiving terminal state to the visited network switch A home that transmits an inquiry message and transmits a prepaid billing request message for an incoming call to the home network exchange if the called terminal is in a normal state and the called terminal user is a prepaid billing subscriber based on the called terminal status message received from the visited network exchange. A home network switch which transmits an incoming terminal status inquiry request message to a location register and the home location register, and requests a prepaid billing process for an incoming call to a service control device of a home network upon receiving the prepaid billing request message from the home location register. Prepaid billing when roaming overseas, including A system is provided.
The home location register receives a location request message from the routing exchange when the routing exchange receives a call setup request message from the originating exchange, and if the home location register receives the location request message, whether the called terminal is located in an overseas visited network. If it is located in the overseas visited network, the routing request message including the home network exchange information capable of prepaid billing is transmitted to the routing exchange, and when the routing exchange receives the routing request message, the call is sent to the home network exchange capable of prepaid billing. It characterized in that the routing.
The home network switch is characterized in that the switch in conjunction with the service control device for performing the intelligent network processing function including the prepaid billing processing function.
The routing exchange is a switch that does not interwork with a service control device that performs an intelligent network processing function including a prepaid billing processing function.
The home network exchanger performs a call setup process in association with the visited network exchanger, and provides real time deduction processing by the service control apparatus by providing call start information and call end information for the corresponding call from the home network exchanger to the service control apparatus. It is characterized by that.
When the home location register fails to process prepaid billing in the visited network, the home location register may set a message parameter for processing prepaid billing for an incoming call in the home network.
When the home network exchange fails to process the prepaid billing in the visited network, the home network exchanger may set a message parameter for processing the prepaid billing for the incoming call in the home network.
