Referring to FIG. 1, a UE 101 accesses an intranet 107 through a Node B 103 and a Node B controller (ACR) 105. In addition, the intranet application server 109 is connected to the intranet 107 to provide various applications. The service requester 111 is an entity for developing an application through an open application service according to the present invention. The present invention can support both SOAP and REST. In the present invention, the base station controller 105 is configured to provide the service requester 111 with information for an open application. 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, requests service elements required for the application and receives the corresponding service elements, and then generates an application using the received service elements. In the present invention, the service requestor may be included in the base station controller 200. This is shown at 215 in FIG. Such a case will be described later.

The open service interface unit 201 provides an interface function for disclosing a service provided by the base station controller 200 to the service requestor 213. [ Upon receiving the service request message of the service requester 213, the service requester 213 analyzes the message and transmits the message to the multiple ACR control unit 207 to inquire whether the requested service is the service currently provided by itself. Upon receipt of a response to the inquiry from the multi-ACR control unit 207, if the requested service is a service provided by itself, the service control unit 208 delivers the service request message to the open service controller 208, The service request message is transmitted to the multiple ACR control unit of the corresponding base station controller provided with the service. The service request message may be a SOAP or REST protocol type message, but may be a message of a different protocol depending on the system.

The multiple ACR control unit 207 receives the service request message from the open service interface 201 and transmits the information of the base station controller in which the service exists to the open service interface unit 201. That is, it is determined which base station controller the service requested by the service requester 213 exists, and the information of the base station controller in which the service exists is transmitted to the open service interface 201. If the information is provided in the other base station controller Transmits the service request message received from the open service interface 201 to another base station controller, receives the result, and responds to the service requestor 213. To this end, the multiple ACR control unit 207 shares identification information (ID) between the multiple ACR control units in other base station controllers and the terminals managed by each base station controller. This is to provide a seamless open service to the service requester 213 in a system in which a plurality of base station controllers exist. The manner in which the multiple ACR control unit 207 shares the identification information of the other ACR control units with the terminals will be described later with reference to FIGS. 4A and 4B.

The open service control unit 208 receives the service request message from the open service interface unit 201 and calls the service corresponding to the service request message from the service configuration unit 205. [

The service configuration unit 205 responds to the open service controller 203 with information on the service corresponding to the service request message. The service configuration unit 205 shown in 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 merely an example and other services may be added in addition to the service. Meanwhile, as described above, the service requester 215 may be located in the base station controller 200 in the present invention. When 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 in the base station controller 200, Can be reduced. However, in the present invention, the application hosting unit 209 is further configured to place a service requester in the base station controller 200.

The application hosting unit 209 and the service requester 215 are physically located in the base station controller 200 but are logically connected to the general operation of the base station controller 200 and the above- In a virtual space separated from the virtual space. This is to prevent various errors that may occur due to placing the service requester 215 inside the base station controller 200. [

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

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

The message analyzing unit 301 receives the service request message from the service requester 213, parses the service request message, and transmits the parsed service message to the service checking unit 303. The service checking unit 303 transmits the analyzed service request message to the multiple ACR control unit 207 to inquire which base station controller the service requested in the service request message is provided. If the requested service is a service provided by the multi-ACR controller 207, the ACR controller 207 transmits the service request message to the open service controller 203. The service deciding unit 305 delivers the requested service information to the open service control unit 208 according to the service request message received from the service checking unit 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 illustrate a first base station controller 401 and a second base station controller 409. The following description assumes that the first base station controller 401 transmits a service request message to the second base station controller 409 Assume the situation of delivering. That is, the first base station controller 401 becomes a source base station controller and the second base station controller 409 becomes a destination base station controller.

First, the first multiple ACR controller 403 of the first base station controller 401 receives the system setup data (PLD) from the OAM 407 (Operation, Administration and Maintenance) unit in order to acquire the list of the neighboring base station controllers in step 413 And opens and initializes a UDP socket to receive IP subnet information from the neighboring BS controller. In step 415, it transmits its own subnet information including a request message (Req flag) to the second multiple ACR control unit 411 in the second base station controller 409.

In step 417, the second multi-ACR controller 411 updates the ACR / IP subnet information using the received information, and in step 419, transmits the subnet information of its own to the first multiple ACR controller 403 , The first multiple ACR controller 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.

In the following description, a procedure for sharing the IP subnet information of the first base station controller 401 and the list of neighboring base station controllers with the second base station controller 409 is shown.

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

In step 429, the first multiple ACR control unit 403 transmits its subnet information to the second multiple ACR control unit 411 in order to inform that the subnet information of the first multi-ACR control unit 403 is changed. In step 431, Updates the ACR / IP subnet information using the received information.

If the information of the neighboring base station list of the first base station controller 401 is changed, the OAM 433 transmits the changed neighboring base station controller list information to the first open service interface unit 405 in step 433, The first open service interface unit 405 transmits the neighboring base station controller list information to the first multiple ACR control unit 403, and the first multiple ACR control unit 403 updates the information. 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. 4B, it is assumed that the information of the second base station controller 409 is changed. Accordingly, when the information is transmitted to the second multiple ACR controller 411, the second multiple ACR controller 411 updates the information using the received information do.

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

In step 523, the service requestor 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 525, the first open service interface unit 505 Analyzes the requested service type, and if necessary, transmits a message to the first multiple ACR controller 503 inquiring whether the requested service is a service that can be provided by the first base station controller 501, which is its own base station controller, Step < / RTI > The response of step 527 may be one of three. A response indicating that the corresponding service is provided by the first base station controller 501, a response indicating that the corresponding service is provided by the other base station controller when the corresponding service is provided, And the base station controller does not provide the corresponding service.

If the first base station controller 501 can provide the corresponding service according to the first response, operations of steps 529 to 537 will be described below.

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 will be described later.

Thirdly, if any of the base station controllers does not provide the corresponding service, operation of step 553 is performed. That is, in step 553, the first open service interface unit 505 receives from the first multiple ACR control unit 503 a response that the base station controller address is 0. 0. 0 in the sense that the corresponding service is not provided in any of the base station controllers. And transmits a service failure message to the service requestor 521 when the service request is received.

If the corresponding service is provided by the first base station controller 501, steps 529 through 537 will be described.

In step 529, the first open service interface unit 505 transmits a service request message to the open service control unit 507. In step 531, the open service control unit 507 transmits the service request message to the open service control unit 507, In step 533, it receives the necessary information according to the requested service, and transmits the requested information to the service provider 521 through steps 535 and 537.

Second, the operation when the service is not provided by the first base station controller 501 and the corresponding service is provided by the second base station controller 511 will be described with reference to steps 539 to 551. [

In step 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 step 541, the second open service interface unit 513 transmits a service request message to the second open service controller 515. In step 543, the second open service controller 515 transmits the service request message to the second open service controller 515 The second service configuration unit 517 requests information about the service, receives the corresponding service information in step 545, and delivers the corresponding service information to the second open service interface unit 513 in step 547. The second open service interface unit 513 transmits the corresponding service information to the first open service controller 505 in step 549. In step 551, the first open service controller 505 notifies the service requestor 521 And the corresponding service information is transmitted.

However, if the second base station controller 511 does not provide the requested service, the second open service controller 515 may transmit the requested service to another base station controller The service request message should be transmitted to the mobile terminal. However, if a base station controller does not provide the requested service, the process of transmitting a service request message to another base station controller may be repeated infinitely.

In order to prevent this, when the base station controller transmits a service request received from the service requestor to another base station controller, the base station controller changes the type of the service included in the service request message, So that 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 the service type A, and the second base station controller 511 provides the service type A. [ If the service requestor 521 requests the service A in step 523, the first open service interface unit 505 transmits the service type to the first multiple ACR control unit 503 in step 525, And the response will be received in step 527. If the < RTI ID = 0.0 > Since the service A is not provided by the first base station controller 501, the first multiple ACR controller 503 transmits a response indicating that the service A is provided by the second base station controller 511 to the first open service interface (505). ≪ / RTI >

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. At this time, Change the service type included in the message from A to A '. The service type A 'has the same function as the service type A, but only the service type is changed. If the second open service interface unit 513 receives the service request message and does not directly receive the service request message from the service requestor 521, And may no longer retransmit the service request message to another base station controller even if it does not actually provide the corresponding service. Thus, it is possible to solve the problem that the service request message is repeatedly retransmitted. Accordingly, the second open service interface unit 515 directly calls the corresponding service in the second service configuration unit 517 in step 541 without a separate inquiry to the second multiple ACR control unit 519.

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

6 illustrates an embodiment in which a service requester is located in the first base station controller 601. Therefore, as described above with reference to FIG. 2, in the first base station controller 601, (603) are further included. Accordingly, the service requester 623 operates in a similar manner to that described with reference to 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 the API.

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

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

Meanwhile, when the requested service is not available in the first base station controller 601, the operations of steps 645 to 655 are the same as those of steps 539 to 549 of FIG. The corresponding service information provided by the second base station controller 613 is transmitted to the first open service interface unit 607 through these steps. Thereafter, the 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 response message of rejection in step 651 in order to prevent the time delay of retransmitting the service request message to another base station controller. If the rejection message is generated as described above with reference to FIG. 5, a service response rejection message is transmitted to the service requester 623 through steps 661 and 663.

7 is a view for explaining the operation of the originating base station controller according to the embodiment of the present invention.

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

In step 705, it is determined whether the requested service is supported by the current BS controller. If not, the MS proceeds to step 711 and transmits the service request to the BS controller supporting the corresponding service using the shared information. If the requested service is supported by the current BS controller, the selected service is selected and information about the selected service is extracted and provided to the service requester.

8 is a view for explaining the operation of the receiving base station controller according to the embodiment of the present invention.

Upon receipt of the service request of the service requestor from the neighboring base station controller in step 801, it is determined whether the requested service is supported by the neighboring base station controller in step 803. If the service is not supported, the flow proceeds to step 809 to transmit a response of rejection to the neighboring base station controller. If the service is supported, the service proceeds to step 805 to select the service, and in step 807, information on the selected service is returned to the neighboring base station controller.
