Hereinafter, embodiments of the present invention will be described in detail.

2 is a diagram illustrating a configuration of a base station controller for an open application service according to an embodiment of the present invention.

The service requester 213 is located outside the base station controller 200 to request the service elements required for the application, and after receiving the corresponding service elements, generates an application using the received service elements. Meanwhile, in the present invention, the service requester may be included in the base station controller 200. This is shown at 215 in FIG. 2. This case will be described later.

The open service interface unit 201 provides an interface function for publishing a service provided by the base station controller 200 to the service requester 213. To this end, upon receiving the service request message of the service requester 213, the message is analyzed and transferred to the multiple access control router (ACR) control unit 207 to inquire whether the requested service is currently provided by the service. When the response to the inquiry is received from the multi-ACR controller 207, if the requested service is a service provided by the user according to the response, the service request message is transmitted to the open service controller 208, If it is not a service, the service request message is transmitted to the multiple ACR controller of the corresponding base station controller provided with the service. The service request message is generally a message in the form of a SOAP or REST protocol, but may be a message of another protocol according to a system.

The multi-ACR controller 207 receives a service request message from the open service interface 201 and delivers information of the base station controller in which the service exists to the open service interface 201. That is, when the service requester 213 determines which base station controller the requested service exists in, and transmits the information of the base station controller in which the service exists in the open service interface 201, if the corresponding information is provided from another base station controller The service request message received from the open service interface 201 is transmitted to another base station controller, and the result is transmitted to the service requester 213. To this end, the multi-ACR control unit 207 shares identification information (ID) of terminals managed by each base station controller with the multi-ACR control unit in another base station controller. This is to provide a seamless open service to the service requester 213 in a system where a plurality of base station controllers exist. A method of sharing the identification information of UEs with other ACR controllers 207 will be described later with reference to FIGS. 4A and 4B.

The open service controller 208 receives a service request message from the open service interface unit 201 and calls a service corresponding to the service request message from the service component 205.

The service configuration unit 205 responds to the open service control unit 203 with information about a service corresponding to the service request message. The service configuration unit 205 of FIG. 2 is assumed to support the location tracking service 205-1, the paging service 205-2, the QoS service 205-3, and the broadcast service 205-4. . However, this is exemplary and other services may be provided in addition to the above services. Meanwhile, as described above, in the present invention, the service requestor 215 may be configured to be located inside the base station controller 200. If the service requester 213 is located outside the base station controller 200, there may be a time delay for receiving an open service. However, if the service requester 215 is located inside the base station controller 200, such a time delay may occur. Can be reduced. However, in the present invention, the application hosting unit 209 is further configured to allow the service requester to be located inside the base station controller 200.

This is to prevent various errors that may occur due to the location of the service requestor 215 inside the base station controller 200.

The service requester 215 located in the base station controller 200 is connected to the open service interface 201 through the application hosting unit 209 rather than directly to the open service interface 201. That is, the service requester 215 provides the service requester 215 with an API for providing a service through a library that the service requester 215 has. Examples of the API may be C, Java, Python, Perl languages, and the like.

3 is a diagram illustrating a configuration of an open service interface unit among components of a base station controller according to an embodiment of the present invention.

The message analyzer 301 receives the service request message from the service requester 213, parses it, and delivers the service request message to the service inspector 303. The service checking unit 303 transmits the analyzed service request message to the multi-ACR control unit 207 to inquire which base station controller the service requested in the service request message is provided. Thereafter, the multi-ACR controller 207 receives a response to the query, and if the requested service is a service currently provided by the multi-CRC controller 207, the service request message is transmitted to the open service controller 203. The service determiner 305 transfers the service requested service information to the open service controller 208 according to the service request message received from the service checker 303.

4A and 4B are flowcharts illustrating a method of sharing information between multiple base station controllers according to an embodiment of the present invention.

4A and 4B assume a first base station controller 401 and a second base station controller 409. The following description will be given by the first base station controller 401 to send a service request message to the second base station controller 409. Assume a situation to convey. That is, the first base station controller 401 becomes the originating base station controller and the second base station controller 409 becomes the destination base station controller.

First, in step 413, the first multiple ACR controller 403 of the first base station controller 401 obtains system configuration data (PLD) from the OAM 407 (Operation, Administration and Maintenance) unit to obtain a list of neighboring base station controllers. Read and open UDP socket to receive IP subnet information from neighbor base station controller. Thereafter, in step 415, its own subnet information including a request message (Req flag) is transmitted to the second multiple ACR controller 411 in the second base station controller 409.

In step 417, the second multi-ACR control unit 411 updates the ACR / IP subnet information using the received information, and in step 419, the second multi-ACR control unit 403 updates its subnet information in response to the request message. ), The first multi-ACR control unit 403 receives the subnet information, and updates the ACR / IP subnet information using the received subnet information in step 421. Through this process, information between base station controllers is updated in real time.

On the other hand, the following description shows a procedure for sharing its IP subnet information and neighbor base station controller list in the first base station controller 401 with the second base station controller 409.

If the OAM 407 transmits a message indicating that the IP subnet information of the first base station controller 401 has changed in step 423 to the first open service interface unit 401, the first open service interface unit 401 in step 425. ) Reads the changed IP subnet according to the received message and transmits the changed IP subnet information to the first multi-ACR control unit 403 in step 427 so that the first multi-ACR control unit 403 transmits its own IP subnet. Update the information.

When the first multi-ACR control unit 403 transmits its own subnet information to the second multi-ACR control unit 411 in step 429 to notify that its own subnet information has been changed, the second multi-ACR control unit 411 in step 431. The ACR / IP subnet information is updated using the received information.

On the other hand, if the information of the neighbor base station list of the first base station controller 401 is changed, in step 433 OAM 433 transmits the changed neighbor base station controller list information to the first open service interface unit 405, step 435 When the first open service interface unit 405 transmits the neighbor base station controller list information to the first multiple ACR controller 403, the first multiple ACR controller 403 updates this information. Thereafter, in step 437, the first multiple ACR controller 403 transmits the subnet information of the first base station controller 401 to the second multiple ACR controller 411 of the second base station controller 409. In FIG. 4B, it is assumed that the information of the second base station controller 409 has been changed, and when the corresponding information is transmitted to the second multiple ACR controller 411, the second multiple ACR controller 411 is updated using the received information in step 439. do.

5 is a diagram illustrating a procedure of receiving an open service when a service requester is outside the base station controller according to an embodiment of the present invention.

When the service requester 521 transmits a service request message including the IP of the terminal, the type of service, and the like to the first open service interface unit 505 in step 523, the first open service interface unit 505 in step 525. After analyzing the requested service type, if necessary, the first multi-ACR controller 503 transmits a message inquiring whether the requested service is a service provided by the first base station controller 501, which is its base station controller. Receive the response in step. The response of step 527 may be one of three types. One is a response that the corresponding service is provided by the first base station controller 501, the second is a response that informs information about the base station controller provided by the corresponding service when the other base station controller is provided, and the third is which The response is that the base station controller does not provide the service.

According to the first response, if the corresponding base station controller 501 can provide the corresponding service, operations of steps 529 to 537 will be performed.

If the corresponding service is not provided by the first base station controller 501 according to the second response, and the corresponding service is provided by the second base station controller 501, the operations of steps 539 to 551 are performed, which will be described later.

Third, if no base station controller provides the corresponding service, operation 553 is performed. That is, in step 553, the first open service interface unit 505 receives a response from the first multiple ACR controller 503 that the base station controller address is 0.00.0, indicating that the corresponding service is not provided to any base station controller. In the case of reception, the service failure message is transmitted to the service requester 521.

Then, when a corresponding service is provided by the first base station controller 501, it will be described with reference to steps 529 to 537.

In operation 529, the first open service interface unit 505 transmits a service request message to the open service control unit 507. In operation 531, the open service control unit 507 uses the first service component unit according to the requested service type. In step 509, a service is requested, and in step 533, necessary information is received according to the requested service and delivered to the service provider 521 in steps 535 and 537.

Secondly, an operation when a service is not provided in the first base station controller 501 and a corresponding service is provided in the second base station controller 511 will be described with reference to steps 539 to 551.

In operation 539, the first open service interface unit 539 transmits a service request message to the second open service interface unit 513 in the second base station controller 511. In operation 541, the second open service interface unit 513 transmits a service request message to the second open service control unit 515. In operation 543, the second open service control unit 515 corresponds to the second base station controller 511. If the service is provided, the second service component 517 requests the information on the corresponding service, and receives the corresponding service information in step 545, and transmits the corresponding service information to the second open service interface unit 513 in step 547. In operation 549, when the second open service interface unit 513 transmits the corresponding service information to the first open service control unit 505, the first open service control unit 505 informs the service requester 521 in step 551. The service information will be delivered.

However, in relation to step 545, when the second base station controller 511 does not provide the requested service, in the present invention, the second open service controller 515 provides another base station controller for providing the requested service. The service request message will have to be sent. However, if no base station controller provides the requested service, the process of transmitting a service request message to another base station controller may be repeated indefinitely.

In order to prevent this, when the base station controller forwards the service request received from the service requester to another base station controller, the other base station controller receives the service request message using a method of changing the type of service included in the service request message. The base station controller no longer retransmits the service request message to another base station controller.

For example, assume that the first base station controller 501 does not provide a service type A, but the second base station controller 511 provides the service type A. In this case, if the service requester 521 requests the service A in step 523, the first open service interface unit 505 informs the first multiple ACR control unit 503 of the base station controller in step 525. It will ask if it is provided and will receive the response in step 527. As assumed, since the service A is not provided by the first base station controller 501, the first multi-ACR controller 503 responds that the service A is provided by the second base station controller 511. Will send to section 505.

Thereafter, the first open interface unit 505 of the first base station controller 501 transmits a service request message to the second open interface unit 513 of the second base station controller 511 in step 539. Change the service type included in the message from A to A '. The service type A 'has the same function as service type A, but changes only the type of service. If only the service type is changed and the service request message is included and transmitted, the second open service interface unit 513 which receives the service type is not directly received from the service requester 521, but receives another base station controller. Recognizing that it has been received through the service, even if he does not actually provide the service may no longer retransmit the service request message to another base station controller. In this way, the service request message may be repeatedly retransmitted. Accordingly, the second open service interface unit 515 directly calls the corresponding service from the second service component 517 in step 541 without inquiring the second multiple ACR controller 519.

6 is a diagram illustrating a procedure of receiving an open service when a service requester is inside a base station controller according to an embodiment of the present invention.

Accordingly, the service requester 623 operates similarly to that described in FIG. 5 except that the service requester 623 is connected to the first open service interface unit 605 through the application hosting unit 603 to receive an API.

That is, in step 625, the service requester 623 transmits a service request message including the IP and the service type of the terminal to the first open service interface unit 605 through the application hosting unit 603. Operations of steps 627, 629, and 631 are the same as those of steps 523, 525, and 527 of FIG. If the service requested by the service requester 623 is available from the first base station controller 601, the operations of steps 633 to 643 are performed, and if the service is not provided, steps 645 to 659. The operation of is performed.

In the case where the requested service can be provided by the first base station controller 601, the operations of steps 633 to 639 are the same as the operations of steps 529 to 535 of FIG. 5, through which the requested service information is determined. It is delivered to the open service interface unit 607. In operation 609 and 611, the service information is transmitted to the service requester 623 through the application hosting unit 609.

On the other hand, when the requested service is not available from the first base station controller 601, the operations of steps 645 to 655 are the same as the operations of steps 539 to 549 of FIG. Through these steps, corresponding service information provided from the second base station controller 613 is transferred to the first open service interface unit 607. Thereafter, corresponding service information is provided to the service requester 623 through steps 657 and 659.

However, if the second base station controller 613 does not provide the requested service, the second base station controller 613 generates a rejection response message in step 651 to prevent a time delay of retransmitting the service request message to another base station controller. As described above with reference to FIG. 5, when the rejection message is generated, the response message of the denial of service service is transmitted to the service requester 623 through steps 661 to 663.

In step 701, shared information is received from a neighbor base station controller and updated. The shared information includes subnet information managed by each base station controller. In step 703, a service request is received from a service requester. The service requester may be located outside the base station controller or inside the base station controller. When located inside, the base station controller includes an application hosting unit in a logical space that is logically separated so that the service requester receives a service request through the application hosting unit.

In step 705, it is determined whether the requested service is currently supported by the base station controller. If it is not supported, the process proceeds to step 711 and the service request is transmitted to the base station controller supporting the service using the shared information. If the requested service is currently supported by the base station controller, the service is selected and information about the selected service is extracted and provided to the service requester.

8 is a diagram illustrating an operation of a receiving base station controller according to an embodiment of the present invention.

In step 801, when the service request of the service requester is received from the neighbor base station controller, in step 803, it is determined whether the service is supported. If the corresponding service is not supported, the process proceeds to step 809 and a response of rejection is transmitted to the neighbor base station controller. On the other hand, if the corresponding service is supported, the process proceeds to step 805 to select the service and in step 807 responds to the information about the selected service to the neighbor base station controller.
