Description

How to reference location information in service independent blocks

The present invention relates to a method of referencing location information in a service independent block.

In a mobile communication network, when a user moves, a communication service is controlled. However, since elements of a network providing a service are different according to a user's current location, service control must be performed accordingly.

Conventionally, for this purpose, the service related to the user location is handled between the switch and the user location register. However, in the next generation mobile communication network, service control is separated into a service control function.

Accordingly, there is a need for a method of referring to location information of a user in service logic for efficiently providing a service with a separate service control function of a next generation mobile communication network. In addition, in order to provide an intelligent network service in a mobile communication network, a current intelligent network based on a fixed network requires a service independent block related to a location of a user essential for wireless paging or messaging services in addition to the service independent blocks defined in the related art.

Accordingly, the present invention has been made in accordance with the above-described requirements, and the position information which can refer to the user location information using a service independent block referencing the user location while executing the service logic to control the intelligent network service in the mobile communication network. The purpose is to provide a reference method.

First, the call control agent function unit 101 of the mobile terminal provides service access of a user and is responsible for call processing. When the connection control agent function unit 102 does not exist, the call control agent function unit 101 also performs connection processing together with the call processing. In addition, the connection control agent function unit 102 controls the connection processing of the user, and the movement control function unit 103 is in charge of service connection control logic and processing on the core network side.

In addition, the call control function / service switching function 104 on the core network side provides functions required for controlling call processing and interacting with the service control function, and there is no connection control function 105 present. If not, the connection processing is performed in addition to the call processing, the connection control function 105 controls the connection processing, and the service access control function 106 provides call related and non-call related processing and control.

In addition, the location management function 107 on the core network side has basic terminal mobility logic and provides location management, mobility management, active state management, and identity management, and the authentication management function 108 manages storage and access of authentication data. Responsible for providing authentication and confidentiality control, the service control function unit 109 includes the overall intelligent network service control function of the next generation mobile communication network, and the service data function unit 110 stores and accesses data related to the service.

Service features c 314, service features z 313, and the like.

Each service feature consists of one or more Service Independent Blocks (SIBs). For example, service feature b 312 is composed of service independent block 2 322, and service feature z 313 is composed of service independent block 5 325 and service independent block 6 326.

On the other hand, the service can be controlled as a continuous process of arithmetic operations of the service independent blocks of these service features. For example, service A 301 may configure its service logic in each operation operation of service independent block 1 321 to service independent block 6 326, respectively.

4A and 4B are flowcharts illustrating an embodiment of a method for referring to location information in a service independent block according to the present invention, in which the service independent block performs a routing information checking operation, a location monitoring request operation, and a location change notification operation.

As shown in the figure, when the service control function requests the user's location while performing the service logic, the routing information confirmation operation transmits the routing information confirmation request signal to the location management function through the routing information confirmation operation (401), and confirms the routing information from the location management function. If it is determined that the response signal has been received (402) and if the routing information confirmation response signal is not received, it is determined whether the number of retransmissions exceeds a predetermined number (403). If the predetermined number does not exceed, the routing information confirmation request signal transmission process is repeated. .

On the other hand, if it is determined whether the routing information confirmation response signal received from the location management function unit (402) and receives the routing information confirmation response signal, it is determined whether an error exists in the received routing information confirmation response signal (404) The service logic is continuously executed and terminated using the received routing information (405), and if there is an error, whether the existing error is a retryable error such as a bursting event, a serious error such as an illegal subscriber, a lost terminal, or power. It is determined whether the error can be performed later, such as OFF (406). If it is a serious error, it is terminated. If the error is retryable, it is determined whether the number of retries exceeds a predetermined number (407). Repeats the signal transmission and if the error can be performed later, the service control function requests the position monitoring. Position management through the operation part and transmits the user location monitoring request signal 408.

Thereafter, the service control function determines whether the user location monitoring request response signal has been received from the location management function (409). If the user location monitoring request response signal is not received, it is determined whether the number of retransmissions exceeds a predetermined number (410). If the user does not exceed the predetermined number of times, the user location monitoring request signal is repeatedly transmitted. If the user location monitoring request response signal is received, the service logic stops executing and waits (411).

Subsequently, the service control function determines whether the location change notification signal has been received through the location change notification operation of the location management function (412), and if the location change notification signal is received, the service logic execution is resumed using the received location change information ( 413). That is, the location management function confirms the location of the registered user through the location change notification operation, and transmits a location change notification signal to the service control function to inform the confirmed user location, and the service control function resumes performing the service logic. do.
