Description

Measurement Statistics Verification Method of Base Station Control Processor in Mobile Communication System

The present invention relates to a mobile communication system, and more particularly, to a method for verifying a software block that is responsible for measurement and statistics on resource allocation of a base station control processor (BCP).

In general, a mobile communication system is a system that allows a mobile station (mobile terminal) to communicate while moving. In addition, the base station control processor performs call processing control, selector management, and system maintenance tasks such as call setup, call release, soft handoff support, hard handoff support, paging support, selector management, overload control, and resource (vocoder). A processor that performs management and so on.

Such a mobile communication system includes a mobile station (MS) 10 that is operated while moving or stopping at a point not specified, as shown in FIG. A base transceiver station (BTS) 20 which receives a call processing request of the mobile station 10 and transmits a call transmission request of a base station control processor 30 to the mobile station 10; A base station control processor (BCP) for controlling the base station 20 to perform signal processing between the base station 20 and the switching center 40; It is connected to the base station control processor 30 and transmits the call processing request of the mobile station 10 to a public switching network (PSTN) or another mobile network and AMPS (Advanced Mobile Phone Service) through a public or dedicated network Mobile Switching Center (MSC) 40 to enable a mobile communication service.

In the general mobile communication system configured as described above, if the subscriber intends to use the mobile communication service while having the mobile station 10 within the service radius of the switch 40, the switch 40 is in control of the base station control processor 30. Accordingly, the mobile station 10 was operated to identify the location of the mobile station 10 and to perform a voice / fax information service according to the request of the mobile station 10 or to connect with another communication network to perform a mobile communication service.

In the general mobile communication system configured and operated as described above, the conventional outgoing signal processing method, as shown in Figure 2, when the call setup request is transmitted from the mobile station 10 to the base station control processor 30 through the access channel, the base station The control processor 30 responds to the call setup of the mobile station 10 via the paging channel (ST1) (ST2); The base station control processor 30, after making the call setup, allocates a channel to the traffic channel to make a call between the mobile stations 10 (ST3); When the call between the mobile stations 10 is completed, requesting release of the call to the base station control processor 30 in the traffic channel to release the call (ST4).

In the conventional signal processing method configured as described above, in order to test the measurement statistics block, in the laboratory, people pick up the mobile terminal (mobile station) 10 and attempt to make a call, hang up and repeat the recorded number of attempts and the result of the measurement statistics block. The measurement statistics block was tested in comparison.

However, if the average number of call attempts of the base station 20 is 20,000 calls per hour, it is not an easy task in terms of time and cost. In addition, in the case of handoff or location registration, it is very difficult to obtain a testable situation. And it is more difficult for a person to generate a call more if it is a measurement item when the frequency of occurrence is rare or when a call is generated by a combination of several situations. In general, even when applied in the field, its accuracy cannot be measured. If the measurement statistics are inaccurate, there is a difference in the service quality indicators of the operator and the call quality felt by the user, resulting in economic loss by failing to obtain indicators of user complaints or operators' excessive facility investment. .

Most systems work well under light loads, but are prone to errors under heavy loads. However, when a person makes a call to a terminal, it is difficult to prepare a manpower and the number of terminals required to create an overload condition. Eventually, after the functional test in the state of low load is applied to the field to observe, there is a problem in that it is difficult to determine the error itself and the cause is also difficult because various situations occur.

In addition, in order to apply the software in general, the service should be interrupted, but the test is not good, and repeated application causes a problem of poor service quality.

Accordingly, the present invention has been proposed to solve the conventional problems as described above, and an object of the present invention is to verify a software block that is responsible for measurement and statistics on resource allocation of a base station control processor (BCP). The present invention provides a method for verifying measurement statistics of a base station control processor in a mobile communication system.

Hereinafter, an embodiment according to the technical concept of the method for verifying measurement statistics of a base station control processor in the mobile communication system configured as described above will be described in detail.

3 is a flowchart illustrating a method for verifying measurement statistics of a base station control processor according to the present invention.

As shown therein, initializing the system and setting a call generation interval timer (ST11-ST15); Setting a call interval timer and then setting up a call setup and a traffic channel on a mobile channel (ST16-ST23); If the mobile channel is set up, maintaining the call state until the end of the test time, transmitting a call release request and recording the statistics of the call state (ST24-ST26)

Initializing the system and setting a call generation interval timer (ST11-ST15) includes: initializing data and a work window of the RS-422 interface card and the channel card (ST12-SR13); Inputting a call generation interval and a test time after performing the initialization (ST14); After inputting the call generation interval and the test time, the call generation interval timer is set.

In step ST16 to ST23, the call setup request and the traffic channel setup for the mobile channel may include: determining whether a call setup request has been received by transmitting a call setup request (ST16); Determining whether a request for establishing a traffic channel (14) has been received (ST18) when the call setup request is received; Transmitting a setting request to the traffic channel 14 upon receiving the setting request of the traffic channel 14, and determining whether a call setting request of the call processing processor 16 has been received (ST19); Transmitting a call setup request to the call processing processor 16 when receiving a call setup request from the call processor 16, and determining whether a setup request for a mobile channel has been received (ST21) (ST22); Upon receiving the setup request for the mobile channel, a setup completion is transmitted to the mobile channel to set up a call and traffic (ST23).

The operation of the method for verifying the measurement statistics of the base station control processor in the mobile communication system according to the present invention configured as described above will be described in detail with reference to the accompanying drawings.

First, the present invention provides the All Receive mode in the local test node of the base station 20. When the personal computer is connected to the node, the interprocessor communication (IPC) message sent from the base station control processor to the channel card is intercepted. As a result, a virtual call simulator can be created using a personal computer, and a personal computer can be manipulated outside of the system to create various situations in a base station control processor to test a measurement statistics block.

So we initialize the system and set the call interval timer. That is, the data and work windows of the RS-422 interface card and the channel card are initialized (ST11 to ST13), the call generation interval and the test time are input (ST14), and the call generation interval timer is set (ST15).

After setting call interval timer, call setup and traffic channel are set up for mobile channel. That is, the call setup request is transmitted to determine whether the call setup request has been received (ST16) (ST17), and when the call setup request is received, it is determined whether the setup request of the traffic channel 14 has been received (ST18). Therefore, upon receiving the setup request for the traffic channel 14, the setup request is transmitted to the traffic channel 14, and it is determined whether the call setup request of the call processing processor 16 has been received (ST19) (ST20). Upon receiving the call setup request from the call processor 16, the call setup request is transmitted to the call processor 16, and it is determined whether the setup request of the mobile channel is received (ST21) (ST22), and the setup request of the mobile channel is requested. When receiving the signal, the set-up is transmitted to the mobile channel to set up call and traffic (ST23).

When the mobile channel is set up as described above, the call state is maintained until the test time ends, the call release request is transmitted, and the statistics of the call state are recorded (ST24-ST26).

So if you want to make 20,000 units per hour, just make a call every time calculated using a timer, and simply hang up and 20,000 units are automatically generated. If you want to perform a handoff, you need to create an address and ID and request a handoff, as if you were sending a channel card that is currently in progress.

This will be described with reference to the processing flow between the personal computer and the base station control processor of FIG.

First, the test node of the base station local network called BIN (BTS Interface Network) is changed to All Receive mode so that the base station control processor can receive IPC messages sent to other devices. It connects to a personal computer using an RS-422 interface cable and an RS-422 High-Level Data Link Control (HDLC) interface card, and defines the messages sent from the base station control processor to the personal computer. Respond appropriately according to the flow of call processing, or make appropriate requests to make the desired state.

So you can simply answer the message A with the message B, but by adding various responses, you can perform complex case tests. By modifying the program according to the test plan, you can perform verification with a large number of calls or test for a long time without a lot of manpower and terminals.

As such, the present invention verifies a software block that is responsible for measurement and statistics on resource allocation of the base station control processor.

As described above, in the mobile communication system according to the present invention, the method for verifying the measurement statistics of the base station control processor is applied to the base station control processor by applying various situations such as the number of handoffs between base stations, the number of handoffs between sectors, and subscriber location registration. By placing the virtual call, the measurement error of the base station control processor can be predicted in case of the unexpected due to the change of the base station environment.

In addition, the present invention can perform various call attempts and overload conditions, interactions by combinations of various states, and long-term tests, thereby minimizing manpower and service interruptions required to perform the test in the field. do.
