[0002]

2. Description of the Related Art In a cellular mobile radio telephone switching system in which an intra-cell communication channel is allocated and a radio line is connected,
A communication channel corresponding to the required maximum traffic volume is allocated in advance according to the traffic demand forecast of each cell.

[0003] Further, since radio equipment is arranged for each cell, the communication channel is fixed regardless of actual traffic during operation.

[0004] For this reason, an increase or decrease in the call traffic in each cell causes a surplus of the call channel or a shortage of the call channel.

[0005]

By the way, when performing packet communication in the cellular mobile radio telephone switching system, the responsiveness changes due to the increase or decrease in the call traffic described above.

In addition, when the response of the network ahead of the base station is poor, the responsiveness is deteriorated.

In this case, if it is determined that the load on the base station side is high, it is possible to wait until the load becomes light, or to move to another place and perform packet communication again.

However, it is impossible for a user of a mobile phone as a mobile station to judge such a deterioration in responsiveness. For this reason, the user has to wait until the deterioration of the response is improved, so that there is a problem that the user wastes time.

The present invention has been made in view of such circumstances, and provides a mobile phone with a traffic monitoring function capable of easily determining responsiveness due to an increase or decrease in call traffic, and a traffic monitoring method therefor. Is to be able to do.

Embodiments of the present invention will be described below.

FIG. 1 is a block diagram showing an embodiment of a mobile phone with a traffic monitoring function according to the present invention. FIGS. 2 to 5 are diagrams for explaining the operation of the mobile phone with a traffic monitoring function shown in FIG. It is.

A portable telephone with a traffic monitoring function (hereinafter simply referred to as a portable telephone) shown in FIG. 1 includes a transmitting / receiving antenna 1, a transmitting circuit 2, a receiving circuit 3, a modulating circuit 4, a demodulating circuit 5, a control unit 6, and a display unit 7. It has.

The transmitting and receiving antenna 1 transmits and receives signals. The transmission circuit 2 transmits a radio signal to the base station via the transmission / reception antenna 1. The receiving circuit 3 includes a transmitting / receiving antenna 1
To receive a transmission signal from the base station.

The modulation circuit 4 converts a binary signal "1" or "0" into a transmittable signal. The demodulation circuit 5 converts the signal received via the receiving circuit 3 into a binary signal of “1” and “0”.

The control section 6 includes a transmission management section 61, a signal encoding section 62, a signal demodulation section 63, and a CPU 64.

The transmission management unit 61 confirms whether the base station is in a receivable state when transmission data is generated, and starts transmission at a prescribed timing to the base station when receivable.

The signal encoding unit 62 performs scrambling processing on data transmitted from the CPU 64 to the base station using a scramble code predetermined by the base station.

The signal demodulation unit 63 performs a descrambling process on the signal from the base station with the determined scramble code, and outputs the result to the CPU 64, as opposed to the signal encoding unit 62.
Transmit to

The CPU 64 as control means analyzes the data received from the signal demodulation unit 63, determines whether the data is from the own station, the other station, or idle data, and counts up the other station data and idle data for a specific time.

The CPU 64 estimates the number of mobile stations performing packet communication in the same cell (same packet channel) from the result of counting up the number of other stations in a specific time.

Further, the CPU 64 calculates a time ratio other than the idle data within the specific time from the count up of the idle data, and causes the display unit 7 to display the number of mobile stations and the time ratio.

Next, the operation of the portable telephone having such a configuration will be described with reference to FIGS.

In the following description, the present embodiment will be described for the case where a physical channel for packet communication of the TDMA system is used.

Since the mobile phone as a mobile station does not know at what timing from the base station and in which subframe the data addressed to itself is transmitted, it is necessary to receive all the subframes. . Therefore, the receiving circuit 3 of the mobile phone needs to be always in the receiving state.

A radio signal from the base station is received by the receiving circuit 3 via the transmitting / receiving antenna 1 (step A).
1). The radio signal received by the receiving circuit 3 is converted by the demodulation circuit 5 into a binary signal of “1” and “0”.

The converted signal has been encrypted. Therefore, the signal demodulation unit 63 performs scrambling processing using the scramble code specified by the CPU 64.

The demodulated signal is passed to the CPU 64. The CPU 64 performs a data analysis process for each specific slot shown in FIG. Here, data analysis is performed on which mobile station is the mobile phone from the reception slot number. The analyzed data includes signal configuration information Wr =
There is a head unit, a continuation unit, and a last unit having 1 to Wr = 5.

Next, the CPU 64 extracts W (Wo) information, which is the signal configuration information shown in FIG. 4A, and determines whether or not it is an idle unit (step A2).

Here, F1 indicates a non-head unit when it is 0, and indicates a head unit when it is 1. F2 is
0 indicates a non-final unit, and 1 indicates a final unit.

Then, in FIG. 4A, the F of the W information
If 1, F2, and W0 are all 0, it is determined that the idle unit. When the data of the specific slot received is an idle unit, as shown in FIGS.
The idle unit count is incremented by one (step A3).

On the other hand, if the received data of the specific slot is not an idle unit, the F information of W information
Based on the information of F2 and W0, a unit combining process for combining the received data excluding the W information is performed at the time when all the units from the first unit to the last unit are obtained (step A).
4).

Further, the CPU 64 performs a layer 2 analysis process on the data for which unit combination has been completed, and identifies a mobile station identifier (hereinafter referred to as MSI) indicating to which mobile station the data is addressed.
Is extracted (step A5).

Further, the CPU 64 determines from the extracted MSI information whether or not the number of MSIs counted so far has the same value (step A6).

If the MSI information has not been counted, the MSI count is incremented by one (step A7). Then, the processing of (Step A1) to (Step A7) is repeated for a specific time (Step A)
8).

The specific time is set to a value determined when the power of the portable telephone is turned on. The method of calculating the specific time is obtained by, for example, the following calculation formula.

Specific time = (number of previously calculated mobile stations) ² × 10 msec However, if there is no previously calculated value, it is set to 5.

Here, the ratio between the number of slots that can be transmitted within a specific time and the number of idle unit counts is 100%.
The value subtracted from the value is the transmission ratio of the base station.

The CPU 64 causes the display unit 7 to display the ratio. A display example on the display unit 7 is as shown in FIG. Further, the CPU 64 detects the MS detected within a specific time.
The number of mobile stations that can be estimated from the I count is also displayed on the display unit 7 (step A9).

After performing display control on the display unit 7, the CPU 64 recalculates the specific time from the MSI count (step A10). Further, the CPU 64 clears the count number of the idle unit and the MSI count number to 0, and repeats the above processing until the specific time comes again.

By such processing, the latest traffic of the cell in which the cell is located is displayed on the display unit 7.

As described above, in the present embodiment, the control unit 6
The CPU 64 always receives and analyzes the downlink signal from the base station in the cell in which it is located, detects the use efficiency of the packet channel in the cell, and causes the display unit 7 to display the detection result. Therefore, it is possible to easily determine the responsiveness due to the increase or decrease of the call traffic.

Thus, when there is a lot of call traffic, not only can it be easily predicted that the responsiveness of the packet communication will deteriorate, but also the responsiveness of the packet communication can be easily determined from the display contents of the display unit 7. Since it can be predicted, wasting time is prevented.

Further, even when the mobile terminal moves to another cell, the responsiveness of the packet communication can be determined by checking the display contents of the display unit 7.

Further, if many users check the display contents on the display unit 7 and perform communication during a time period when the call traffic is small, the traffic of the packet communication can be suppressed.

[0046]

As described above, according to the portable telephone with a traffic monitoring function and the traffic monitoring method according to the present invention, the control unit always receives the downlink signal from the base station in the cell where the cell is located. In addition to the analysis, the use efficiency of the packet channel in the cell is detected, and the detection result is displayed on the display means, so that it is possible to easily determine the responsiveness due to the increase or decrease of the call traffic.
