The present invention relates to a method for testing the establishment and release of an internet call in a radio network controller (RNC) of a broadband wireless mobile terminal (IMT-2000). The present invention relates to a method for testing Internet call establishment and release in a broadband wireless mobile station base station controller suitable for testing the establishment and release of an Internet call without interworking with a mobile communication system.

In recent years, the IMT-2000 system, which is rapidly progressing in the development of commercialization and standardization technology and application technology, has been named by the International Telecommunication Union (ITU) in the global participation in Europe, the United States, and Japan. It is a 3rd generation mobile communication system that is standardized for service between 2000 and 2000, and aims to realize a multimedia service using a broadband wireless mobile terminal.

Such an IMT-2000 mobile communication system, as shown in FIG. 1, has a mobile switching center 102, a location register 104, a base station controller 106, a base station 108/1-108 / n and a mobile terminal 110. / L-110 / n, 112/1-112 / n).

Referring to FIG. 1, the Mobile Switching Center (MSC) 102 performs control of connection (call establishment and call release, etc.) between mobile stations (MS) registered through a PSTN, an ISDN, and the like. Based on the location information of the mobile terminal provided from the base station controller 106, the mobile station performs control of location registration, change, and release of the mobile terminals, and also controls data communication and internet communication in the mobile terminal.

In addition, the location register 104 includes a home location register (HLR) and a visitor location register (VLR), which includes location information on mobility of subscribers (or mobile terminals) and additional services. And stores subscriber identity information and the like, and retrieves the request of the mobile terminal or subscriber from the mobile switching center 102 and provides the same to the mobile switching center 102.

On the other hand, the mobile switching center 102 has a plurality of base station controllers (RNC) 106 (only one base station controller is shown in FIG. 1 for convenience), and each base station controller 106 has a plurality of base stations (BS). 108/1-108 / n, and each base station (e.g., 108/1) is subject to a plurality of mobile terminals 110/1-110 / n included in the service area.

That is, each base station (BS) is in charge of the mobile communication service for each terminal in its service area, for example, various data received from the mobile terminal (MS) that requested (or requested) the service (e.g., For example, voice, text, video data, etc.) may be transmitted to the base station controller 106, and various data provided from the base station controller 106 may be wirelessly transmitted to the corresponding mobile terminal MS, and any mobile terminal MS may also be used. Provides a corresponding connection request message to the base station controller 106 when there is an Internet access service request from the mobile station. When the web site information is provided from the base station controller 106 with a call for the Internet connection, MS).

In addition, each base station (BS) detects when any mobile terminal (MS) is out of its service area and reports to the base station controller 106 in charge (ie, location change report of the mobile terminal), When a new mobile station (MS) enters its service area from another service area, it is detected and reported to the base station controller 106 (that is, the location registration report of the mobile terminal).

On the other hand, the base station controller 106 performs a function of matching between the mobile switching center 102 and the base station BS, for example, converting a 2.048 Mbps E1 signal received from the base station BS into a 155 Mbps STM-1 signal. Multiplexing is transmitted to the mobile switching center 102 through an optical cable (not shown), and the STM-1 signal provided from the mobile switching center 102 is demultiplexed into an E1 signal and transmitted to the base station BS.

In addition, the base station controller 106 connects between the Internet network and the corresponding mobile terminal (that is, the mobile terminal requesting the Internet connection) through a router when an Internet connection request message (HDLC data) is received from the base station BS, When the website information is received through the router, it is processed and delivered to the base station (BS).

Accordingly, the call set in any mobile terminal (ie, a virtual mobile terminal) is released under the control of the base station controller (RNC), that is, the call resources of the wired and wireless are released.

On the other hand, the mobile switching center simulator 306 generates a service release message (RELEASE) to release the call of the established Internet network side and delivers it to the base station controller (RNC), in response to the base station controller (RNC) in the RNC main processor 304 An Internet service connection release request message (IS_REL_ORD_REQ) is generated and delivered to the Internet service processing block 418 via a signaling processing path via My API 416 → RCC 406 → RRC 412 → IB 402. . Thus, the incoming wired resource allocated to the virtual internet network is released.

In addition, the base station controller (RNC) generates an Internet service release completion message (RELEASE COMPLETE) via the signal processing path via the RCC 406 → API 416 in the RNC main processor 304 to exchange the mobile switching center simulator 306. As a result, the Internet call is released between any virtual originating terminal and the virtual Internet network, i.e., the wired and wireless call resources are released.

Therefore, the Internet call set up between any virtual originating terminal and the virtual internet network is properly released using the base station simulator and the mobile switching center without physically interworking the base station controller with the base station and the mobile switching center through the process described above. Can be tested.

On the other hand, the test operator can monitor the test process of the release of the set Internet call through a monitor provided in a workstation (not shown) connected to the test system, and if necessary, various kinds of problems that occur during the process of releasing the set Internet call using a printer. It is also possible to output the result data for the generation of a message.

Therefore, when an error occurs in the process of releasing the established Internet call, the test operator can easily know at what stage and for what reason. The error can be reliably analyzed and healed when an error occurs.

As described above, according to the present invention, unlike the above-described conventional method of testing the establishment and release of the Internet call in the state of physically interlocking the respective equipments (base station, base station controller, mobile switching center), the base station controller is moved from the base station and the mobile station. Since the base station simulator and the mobile switching center simulator can be used to test the establishment and release of the Internet call without physically interworking with the switching center, the time and cost of testing the establishment and release of the Internet call at the base station controller are greatly reduced. Can be saved. In addition, the present invention can effectively suppress the test site constraints required for testing Internet call setup and release at the base station controller.
