Description

Call processing test method between personal mobile switching center and home location register

The present invention relates to a call processing test method between a personal mobile communication exchange and a home locaion register (HLR) of a personal communication service exchange (PCX), in particular, the SS NO.7 scheme. In addition, the present invention relates to a call processing test method between a personal mobile communication exchange and a home location register simulator for transmitting data.

Personal mobile communication exchange is a next-generation mobile communication service (PCS) service, which is a next-generation mobile communication service, which is expected to be a pedestrian-oriented universal and diverse service, whereas existing cellular mobile communication is a vehicle-oriented service in the 800 MHz band. It is an exchanger. Such a personal mobile communication exchange uses the SS NO.7 scheme when transferring data between different exchanges or home location registers.

The SS NO.7 scheme used is a map (mobile application part: MAP) 120, a question-and-answer processing unit (transaction) with the application part (AP) 110 as a top layer as shown in FIG. capability application part: hereinafter abbreviated as ticap) (130) Signaling connection control part (hereinafter abbreviated as SCCP) (140). The message transfer part (hereinafter, referred to as MTP) 150 has a hierarchical structure.

Application service unit 110 is at the top and serves to connect the system of the exchange to provide direct application services to the communication users, the map 120 is implemented using a special facility, the question and answer function for mobile communication The TCAP 130 performs a question-and-answer function, and does not directly correspond to the control of the communication line, but a mobile communication function to various applications distributed in exchanges and special centers such as databases, OA & M centers, and the like. And protocol. SCCP 140 is to enable the transmission of various signals and data in addition to the control signal for the normal line, and to provide additional services for information transfer between the exchange and the special center, and for transmission of line and non-line related signal information. Provides connectionless and connected network services. The MTP 150 is then responsible for sending a signaling message to the counterpart signal station, i.e., the home location register 160.

In the call processing test between the personal mobile communication exchanger 100 and the home location register 160 using the SS NO.7 method having a hierarchical structure, the message received from the application service unit 110 is processed in a map and then the T-cap And the home location register to the home location register via SCCP and MTP, and the response of the home location register to the transmitted data is again passed from the lower layer to the upper layer of SS NO.7. It is transmitted to the application service unit 110 to determine the call processing test results.

As such, when the call processing test between the exchange and the home location register is performed through all the electric field layers of SS NO.7, it takes a lot of time, and because the test is performed while occupying the line, the corresponding line is not available and hard. There was a drawback that the call processing test was impossible when the home location register was not connected by wear.

Accordingly, the present invention has been made to solve the above-mentioned shortcomings, and when the call processing test between the personal mobile communication exchange and the home location register, the home location register simulator is operated inside the exchange to call between the personal mobile communication exchange and the home location register. The purpose is to provide a treatment test method.

In order to achieve the above object, a call processing test between a personal mobile communication exchange and a home location register simulator according to the present invention is directed to a call processing test method between a personal mobile communication exchange and a home location register which transmits information by the SS NO.7 method. 1. The method of claim 1, wherein, if a call processing test is required, the subscriber matching unit transmits the requested message in the order of an application service unit and a map layer, which are the highest layers in SS NO. A second step of performing a simulation on the message which has been processed for transmission; The home location register simulator results include a third step of transmitting the map layer processing to the application service unit, thereby providing a call processing test method for the home location registration period.

The above and other objects and various advantages of the present invention will be described in more detail from the preferred embodiments of the present invention described below with reference to the accompanying drawings by those skilled in the art.

Next, the operation of the present embodiment will be described with reference to FIGS. 2 to 4.

Referring to FIG. 2, the exchange is largely referred to as an access switching subsystem (hereinafter referred to as ASS) 220, an interconnection network sub-system (hereinafter referred to as INS), 210, It consists of a central control subsystem (hereinafter referred to as CCS) (200) and exchange information between each other.

CCS (200) is a subsystem that performs the overall operation and maintenance of the system, as well as system-wide maintenance, testing and measurement, billing, statistical functions, as well as cartridge tape (CT), magnetic tape (MT), hard disk It performs mess storage control management of (hard disk), etc., various control from the operator, control of output text, and data channel connection with other systems.

The INS 210 is located at the center of the system and serves to connect the ASS 220 with each other or between the ASS 220 and the CCS 200.

The ASS 220 is subject to matching of the base station in case of subscriber and relay line (personal mobile communication exchange (hereinafter, abbreviated as exchange)). Most call processing functions and self-operation are provided with matching, time switch, and various signaling devices. By performing the maintenance function, etc., the system has a horizontally distributed structure.

The home location register simulator 226 is configured to perform the process from the ticap to the home location register 230 during the call processing test between the conventional exchanger and the home location register 230.

3 shows that when a call processing test command between the exchange and the home location register 230 is applied to the ASS 220 via the INS 210 and the CCS 200, the ASS 220 receives the home call processing test command. Check whether it is a test performance request using the location register (step 300).

As a result of the check, when the test using the electric field of the existing SS NO.7 is required, the process proceeds to step 310 and performs a call processing test between the switch and the home location register 230 in the existing manner, and ends the operation.

However, if the check result of the 300 step is required to perform a test using the home location register simulator 226, the flow proceeds to step 320.

In step 320, the ASS 220 transmits the corresponding message to the map 224 through the application service unit 222 of SS NO.7. In operation 330, the signal received by the map 224 is processed into a signal suitable for the home location register simulator 226, and transmitted to the home location register simulator 226.

In operation 340, the home location register simulator 226 is driven. The home location register simulator 226 accesses the home location register 230 from the layer below the TCAP layer of the SS N0.7 layer and the message between the exchange and the home location register 230 after connecting to the home location register 230. Message transmission and reception processing is performed as shown in FIG. 4 by simulating the transmission and reception processing as in the actual situation.

That is, when the message is received from the map 224 while the home location register simulator 226 is idle, the content of the received message is analyzed in operation 400 of FIG. 4.

As a result of the analysis, when the location request message is received, the process proceeds to step 410 to step 412 to retrieve a location request message response to the mobile communication subscriber call control unit (not shown) from the map 224, where The location information or the failure message generated by the virtual home location register due to the failure or success of the request message request is transmitted (step 414), and returned to the idle state.

In addition, as a result of the analysis, when the request for additional service information is received, the process proceeds to step 420 to step 422 to retrieve additional service information to be sent to the mobile communication subscriber call controller (not shown) from the map 224. In step 424, the server returns to the idle state after transmitting the additional service information or the failure message generated by the virtual home location register 230 due to the failure or success of the request for the additional service information.

As a result of the analysis, when the forwarding number information request message is received, the process proceeds to step 430 to step 432 to retrieve a location request message response to be sent to the mobile communication subscriber call control unit (not shown) from the map 224. The server transmits the forwarding number information or the failure message generated by the virtual home location register due to the failure or success of the forwarding number information request message request (step 434), and returns to the idle state.

In operation 350 of FIG. 3, the map 224 receives a response signal from the home location register simulator 226 from the home location register simulator 226 and uses the received message in the exchange, that is, the application. The service unit 222 processes the processable signal and then proceeds to step 360.

In operation 360, the map 224 transmits the message converted into a signal that can be processed by the application service unit 222 to the application service unit 222, and then proceeds to operation 370.

Then, in step 370, the application service unit 222 receives the processed response message from the home location register simulator 226 for the call test message received from the map 224, and in the subscriber matching unit 220 of the exchange. The processor, for example, the ASP, receives the response message tested by the application service unit 410 and analyzes the message.

As described above, the present invention, by using the home location register simulator 226, it is possible to attempt a call without the home location register 230, so in the case of a personal mobile communication exchange switch exchange interworking test, TCAP ( 130, the SCCP 140, the MTP 150, and the like through the home location register and the personal mobile communication exchange interworking test without the above steps, the application service unit 222, map 224 and home By directly processing in the location register simulator 226, there is an effect that is faster than the previous personal mobile communication switch call test environment.
