The base station 12 allows the mobile terminal 11 to access the network and forwards the service request from the mobile terminal to the mobile service exchange 13. The mobile service exchanger has service logic related to call processing, and connects a call using the location information of the mobile terminal stored in the visited location register 14 and the home location register 15, or visited location register and home location register. Perform the procedure to update the location information. In such a wireless network structure, it is difficult to introduce various services quickly and efficiently because the software of the mobile service exchange must be modified to provide new services. In addition, since the interworking with the intelligent network is impossible, the mobile terminal users cannot use the intelligent network service.

On the other hand, the intelligent network is a function-centralized distributed structure that consists of several network elements such as an intelligent network service switching point (SSP), a service control point (SCP), an intelligent information system (Intellegent IP), and the like. It has the characteristics of providing economically and efficiently services by quickly implementing various and customized services. In addition, the software structure of the intelligent network service exchanger that provides a network access function to the service user and serves as a gateway to the intelligent network has a service-independent structure so that it can be used without modification when changing or adding a service.

Accordingly, an object of the present invention is to provide a service processing method of a base station capable of allowing access to an intelligent network to service users having a mobile terminal and interacting with an existing intelligent network to provide an intelligent network service.

In order to achieve the above object, the present invention provides a service processing method applied to a base station connected to an intelligent network service exchanger and a service control system, which is an intelligent network element, when a service request signal message is received from an originating mobile terminal, the received message is analyzed and serviced. The first step of analyzing the type of the service, and the second step of registering and releasing the calling terminal and notifying the service control system if it is a service requiring connection and disconnection of power, and registering and changing the location of the calling terminal, and registering user location. A third step of notifying and processing the service control system if the service is a request; a fourth step of completing the corresponding radio call processing if the calling terminal requests the handover procedure; and if the calling terminal requests the mobile call originating procedure, A fifth step of performing terminal authentication and user authentication processing and processing outgoing calls; And a sixth step of reporting a paging result response by driving a paging function upon receiving a request for requesting a terminal terminal paging procedure from the system.

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

2 is a configuration diagram of a hardware system to which the present invention is applied. As shown in the drawing, the hardware to which the present invention is applied includes an intelligent network service exchanger 23 and a service control system that use the existing wireless network structure of FIG. (24), the service data point (SDP) 26, and the intelligent network structure in which the intelligent information providing system 25 is introduced.

The intelligent network service exchanger 23 performs a function of an exchange station of an existing wireless network and a service providing an intelligent network service to a service user, and the service data system 25 provides a special network resource to the service user for providing various intelligent network services. It performs the function. In the present invention, the base station 22 requests to provide the intelligent network service by forwarding a call attempted from the mobile terminal 21 to an intelligent network service switch or a service control system, and services the location information of the mobile terminal reported from the mobile terminal. It transmits to the control system so that the service data system (SDP) manages the user's location information. Further, according to a control command of the service control system, the bearer line with the intelligent network service exchanger is standing, maintained, and released, and performs a paging function to the called terminal.

2 illustrates an interface method between the base station 22 and the service control system 24. The base station is designed assuming a network configuration by a direct connection method between the service control systems. This network configuration can directly transmit a large number of messages of the base station reporting the location change of the mobile terminal to the service control system without affecting the data transmission / reception operation between the originating and receiving subscribers.

3 is a software structural diagram of a base station and an intelligent network service exchange according to the present invention, which illustrates an interface method, and provides an intelligent network service exchanger 33, an intelligent information providing system 34, and a service control system 35 to provide an intelligent network service. Shows a software structure of the base station 32 that interacts with < RTI ID = 0.0 >

The base station 32 includes five subs of the wired / wireless interface processor 36, the paging / wireless access / track channel processor 37, the base station radio control / call controller 38, the base station application unit 39, and the protocol processor 40. It consists of a system.

The wired / wireless interface processor 36 performs a radio bearer connection / release function 45 with a mobile terminal and a wired bearer connection / release function 46 to an intelligent network service switch or a mobile service switch, and performs a paging / wireless access / traffic channel. The processor 37 is responsible for the overall management of radio resources such as physical channel allocation and release, and the functions of these two subsystems are the same as in the existing base station. The base station radio control / call control unit 38 receives a service processing request message from the mobile terminal 31 and transmits the intelligent network radio call processing request message to the base station application unit 39 in the case of a service request from an intelligent network service subscriber. In the case of a service request from a non-intelligent network service subscriber, the non-intelligent network radio call processing request message is transmitted (53) to the mobile service exchanger 52, not the intelligent network service exchanger. The base station application section 39 analyzes the type of service reported from the base station radio control / call control section 38, which interacts with the protocol processing section 40 in charge of the protocol with the service control system and controls the service. The system requests the intelligent network service processing and forwards the intelligent network service request response command from the service control system 35 to the base station radio control / call control unit 38 to advance the call.

The exchange call processor 42 of the service exchanger 33, which has received the radio call from the base station via the physical reply interface processor 41, is not responsible for the operation of the standardized basic call processing mode (BCSM). Accordingly proceed with call processing. At this time, the status of the originating call is managed as logical data by the switching center application unit 43 according to DP (Detection Point), which is a component of the basic call processing state model, and the switching center application unit 43 services the protocol processing unit 44. A message for driving the intelligent network service logic of the control system 35 is transmitted.

The protocol processing unit 44 performs an interface function for the network elements to interact with each other. An intelligent network service received from an intelligent network element such as the switching center application unit 43, the service control system 35, or the intelligent information providing system 34. The message is encoded or decoded according to the defined signaling method and delivered to the destination network element (48, 50).

4 shows an overall service operation processing flowchart of the base station.

Upon receiving 101 the service request signal message from the originating mobile terminal, the base station analyzes 102 the received message and determines 103 whether to proceed with the service. If the base station cannot proceed with the service by using the information received from the calling mobile terminal, the service is not available to the calling mobile terminal, and then the radio support and call processing assigned to the call is idle (104). . If the base station can continue to process the service by using the information received from the originating mobile terminal, if the attempt to the non-intelligence network service by analyzing 105 whether the intelligent network service call or the non-intelligent network service call is attempted (105). Request 106 for a wireless non-intelligence network service call to a mobile service exchange. When attempting an intelligent network service call, the requested type of service is analyzed 107 to perform an appropriate intelligent network service procedure.

First, when the calling mobile terminal requests a power-on procedure (108), the base station registers the calling mobile terminal as a terminal that can be controlled by the base station (115), and the terminal is connected to the service control system. Report (117). When the calling mobile terminal requests the power-off procedure (109), the base station deletes the calling mobile terminal from the terminal registration degree that the base station can control (116), and the terminal accesses the service control system. Report (117). When the originating mobile terminal requests a procedure for registering and changing a terminal location or a user location registration procedure (110-112), an intelligent network service processing request message requesting to change the profile of the service subscriber is transmitted to the service control system (118). Wait 119 for a response from the service control system. Receiving a success response message of the service processing from the service control system (120, 121) completes the radio call processing, and if receiving a failure response message retries the service processing within the range allowed by the base station (122, 123). .

If a failure response is received from the service control system even after retrying, the service is notified to the calling mobile terminal and the radio resource and call processing allocated to the call is idle (104). When the calling mobile terminal requests the handover procedure (113), the service control system sends an intelligent network service processing request message (118) requesting to change the profile of the service subscriber and process the handover service, and to control the service. Wait for a response from the system (119). Receiving a success response message of the handover service process from the service control system (124, 125), the information of the control terminal for the cell in the base station is changed (126) and the corresponding radio call processing is completed.

When the failure response message is received, the service process is retried 122 and 123 within the range allowed by the corresponding base station. If the originating mobile terminal requests the mobile call origination procedure (114), it transmits the intelligent network service processing request message (127) requesting the terminal authentication and user authentication processing procedure to provide the mobile call origination service to the service control system, and service control. Wait for a response from the system (119). Upon receiving the success response message of the authentication processing procedure from the service control system (128,129), the process proceeds 130 with the intelligent network service exchanger.

When the base station controls the mobile terminal of the called party, upon receiving the terminal paging procedure request command 131 from the service control system, the base station operates the paging function according to the information 132 of the control terminal in the base station to locate the mobile terminal. Are determined (133, 134). When the location information of the mobile terminal is collected 135, the paging result response is reported to the service control system (136).

Accordingly, the present invention is carried out as described above, the intelligent network designed mainly for the services provided in the fixed network can provide terminal mobility to service subscribers, the existing wireless network using a base station that can be accessed by the intelligent network service logic It is effective to provide a fast and efficient communication service.
