BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to call processing of mobile phones, and more particularly, to display a call processing process between a cellular base station (mobile station) and a cellular phone (terminal: mobile station) so that the data state between the cellular base station and the cellular phone is normal. The present invention relates to an apparatus and a method for displaying a call process between a mobile base station and a cellular phone so as to analyze whether transmission and reception are performed.

The call processing process between the conventional mobile phone base station and the cellular phone (terminal) is specified to follow the protocol specified in the call processing of the Electronic Industries Association (EIA), and the accompanying drawings 1 to 5 When described in detail with reference to as follows.

First, the mobile station transmits the status information of the current system, the terminal registration information message, the terminal control message, etc. in the data format as shown in FIG. 1 through a forward control channel for transmitting a message from the mobile phone base station to the cellular phone.

Here, the basic call processing process of the forward control channel connects the call according to the protocol specification format of the EIA so that the call connection between the mobile phone base station and the cellular phone can be made.

The data format of the above-described forward control channel will be described in more detail as follows.

Busy / Idle (B / I) means that the call loop is not opened while in the busy state, and the mobile phone base station checks the cellular phone call status at any time to check each cell. When a plurality of users of the phone attempts to make a call, the mobile phone base station sequentially establishes a call path.

Even in the cellular standby state, when a cell phone base station and a plurality of cellular phones in a cell site attempt to make a call at the same time, and the call attempt data is sent to the mobile phone branch station, only the first cell phone accepted by the mobile phone base station is in a standby state. And other cell phones create a busy state.

The B / I is inserted every 10 bits, and used to indicate the current state of the reverse control channel (RECC) .If the bit of the B / I is 0, the B / I is recognized as a busy state, and the B / I If the bit is 1, it is recognized as a RECC valid state (IDLE).

The bit position of B / I is inserted every 10 bits. It is located at the start point of 1 bit in B / I, and is inserted at the starting point of Dotting Sync. And the starting point of each Word Sync. It is inserted at the first repetition start point of (Word A) and every tenth message bit to indicate the status of the B / I.

In the above, the dotting function of the communication rule EIA in the forward control channel is for synchronization, and the synchronization of the 10-bit dotting sequence is represented by a binary pulse of 1010101010.

The decimal number 1010101010 + 11100010010 (consisting of 11 bits) is obtained by adding the dot sequence and the word sequence.

These dotting sequences and word sequences are transmission data for enabling the cellular phone to synchronize with received data received from the mobile phone base station.

Each word consists of 40 bits, including parity bits (12 bits), and is transmitted five times.

Next, a message such as a command response message, a call origination message, a terminal registration, and the like are transmitted from the cellular phone to the mobile base station in the second degree and data format through the reverse control channel.

The basic call processing procedure of the reverse control channel is also connected in accordance with the protocol specification format of the basic EIA so that the call connection can be made between the cellular phone and the mobile phone base station.

The format of the reverse control channel will be described in more detail as follows.

The signal transmission format (Singnaling Format) of the RECC is composed of 48 bits, 30 of which are dotting bits, 11 word sync signal bits, and 7 of which are digital color code (DCC) bits.

Each information word is composed of 48 bits, and each word block is composed of 20 bits as five repeated information words.

The maximum data length consists of one Seizure Precusor and five word blocks (A, B, C, D, and E), and consists of a total of 1248 bits.

In each information word consisting of 48 bits, 36 bits are information bits and the remaining 12 bits are parity search bits.

The 48-bit table of information words in the RECC channel format is as follows.

The 7-bit code DCC (Digital Color Field) is a digital signal transmitted through a control channel to a RECC to prevent cellular phone reception errors due to frequency interference with respect to mobile phone base station transmission data.

The error is prevented by different binary code types from the neighboring mobile phone base station to minimize the frequency error of the mobile phone base station in the center and surroundings of the mobile phone base station cell.

On the other hand, on a voice channel obtained as a result of a call call or a call on the control channel, the data is transmitted in a data format as shown in FIG. 3 through a forward voice channel for transmitting voice from the mobile telephone base station to the cellular phone.

In the forward voice channel data format, the basic voice channel call processing process forms a voice channel in accordance with the basic EIA protocol so that a voice channel between the mobile phone base station and the cellular phone can be formed.

The forward voice channel will be described in more detail as follows.

The FVC, which is a forward voice channel, is used to transmit broadband data from the mobile base station to the cellular phone through the voice channel.

Like FOCC, 10Kbps ± 0.1bps is transmitted. Each word consists of 28 information bits and 12 parity bits, and has a total of 40 bits.

In the cellular phone, the word registration signal is repeatedly transmitted 11 times to ensure that the call channel switching message can reach the terminal before the received signal falls below the unreceivable signal.

The FVC signal is mainly used for switching the call channel, and the terminal reception signal at the time when the channel should be switched is usually very weak and needs repeated transmission.

In addition, the reverse voice channel for transmitting voice from the cellular phone to the mobile telephone base station is transmitted in the data format as shown in FIG.

Likewise, in the reverse voice channel, the basic voice channel call processing process connects the call in accordance with the basic EIA protocol specification format so that the voice channel between the cellular phone and the mobile telephone base station can be formed.

The signal type of the reverse voice channel uses 101 toning bits to accurately synchronize the transmission message, followed by 11 bits of word synchronization and 48 words.

There are two kinds of words (Word1, Word2), and each word is transmitted five times.

According to the format of each of these formats, data communication and voice transmission and reception between the mobile base station and the cellular phone are performed in four channel forms.

That is, there are four access channels between the mobile base station and the cellular phone: the forward control channel (base station → terminal), the reverse control channel (terminal → base station), the forward voice channel (base station → terminal), and the reverse voice channel (terminal → base station). To be.

In other words, it transmits the status information of the current system of the corresponding mobile base station, the registration information message of the cellular phone and the control message of the terminal in the data format as shown in FIG. The mobile terminal transmits the command response message, the call origination message, and the registration message of the cellular phone in the data format as shown in FIG. 2 through the reverse control channel for transmitting the message from the cellular phone to the mobile phone base station.

In addition, the voice channel acquired as a result of a call or a call on the control channel is transmitted from the mobile phone base station in the data format as shown in FIG. 3 through a reverse voice channel transmitting voice from the cellular phone to the mobile phone base station. Transmission is performed in the data format as shown in FIG.

FIG. 5 is a flowchart illustrating a call processing process of a conventional cellular phone (terminal). When a mobile phone number is called in order to call a cellular phone that is subscribed to a cellular telephone communication network, the mobile telephone network (PSTN) moves. The mobile telephone terminal is called by a call origination to a MTSO, and the MTSO requests a paging to the mobile telephone base station to which the cellular phone is registered.

The mobile telephone base station receiving the call request transmits a call signal using the control channel.

The cellular phone always monitors the call message of the mobile phone base station transmitting through the control channel, and the mobile phone base station answers the call when the phone number of the cellular phone is called.

The telephone number and the electronic serial number (ESN) sent by the cellular phone are received by the mobile telephone base station and transmitted to the MTSO, which is transferred to the subscriber database. When it is recognized as a valid subscriber compared with the information of, the call channel is composed by allocating a number of voice channels set up by a general telephone network.

However, such a conventional cellular system firstly has a problem in that the call processing process between the mobile phone base station and the cellular phone is not known. Second, the cause of the call connection failure between the mobile phone base station and the cellular phone cannot be known, and the third move. There was a problem that the cause of the call disconnection during the call due to the call connection between the telephone base station and the cellular phone is unknown.

In order to analyze the cause of such a problem, conventionally, a call processing process was measured using a specific frequency measuring instrument. However, this method has a problem in that the measurement data varies depending on the actual measurement area and environmental measurement equipment.

Accordingly, the present invention is to solve the above-mentioned problems of the prior art, an object of the present invention to display the call processing process between the cellular base station (mobile station) and the cellular phone (mobile station) The present invention provides an apparatus and method for displaying a call process between a mobile base station and a cellular phone so as to analyze whether data correspondence between a cellular base station and a cellular phone is normally transmitted and received.
