Abstract

A portable communication terminal by which the user can select either communication through a private base station or communication trhough a public base station. In a call-in detecting mode, whether the communication is made through a private base station or through a public base station, base station switching is automatically carried out such that when the terminal is in the service area of a private base station, the call-in is detected through the private base station; and when the terminal is in the service area of a public base station, the call-in is detected through the public base station. Therefore, the user is not required to make complicated base station switching operation. When the terminal is in both the service areas of private and public base stations, the user can receive the call-in through either of the base stations according to the selection of the user. When the user makes a call, the user can preferentially select the private base station through which the charge is low.

Description

(A terminal device and its control method)

The present invention relates to a mobile communication terminal device and a control method thereof, and more particularly to a mobile communication terminal device selectively connectable to at least two wireless base stations having different charge systems, management systems, and the like, and a control method thereof. Background technology

Conventionally, a mobile terminal device that can be selectively connected to a plurality of types of wireless base stations having different fee structures, management systems, and the like is installed, for example, on a street corner, and has a portable communication terminal device. Mobile communication terminal device that can be selectively connected to a public base station that connects to the network using the terminal number of the network and a private base station that is installed in offices and homes and has wired line infrastructure It has been known.

By the way, in the portable telephone terminal that can be set to switch between communication using the public base station and message using the private base station, the cost is low when calling. It is preferable to set the switch to use the base station. In addition, when making a call, the other party can make a call using the terminal number of the portable communication terminal itself, so the switch is made to use the public base station. There are platforms that you would prefer to set.

Generally, the service area of the public base station is larger than the service area of the private base station. For example, when the portable communication terminal is within the area of the private base station, the private base station is used. In many cases, the portable communication terminal device is switched to use a public base station when the portable communication terminal device leaves the service area of its own base station.

However, for example, this portable telephone terminal is used by the service area of the private S local station.

The operation of the control unit 48 of the terminal device is inconsistent with the flowchart.

In this case, the control unit 48 of the portable communication terminal device continues until the portable communication terminal device enters either the service area of the public base station 30 or the service area of the private base station 20. The process shown in FIG. 3 is periodically repeated.

That is, when this process is started (step 100), first, the incoming call detection mode setting unit 483 sets the incoming call detection setting mode to the private incoming call detection mode or the public incoming call detection mode. Check which one is set (step 101). Here, if the incoming call verification setting mode is set to the private use i-detection mode, first, an attempt is made to receive the control signal (control wave) from the private use base station 20. (Step 102)

Next, it is checked whether or not a control signal (control wave) from the private base station 20 is received (step 103), and here, the control signal (control wave) from the private base station 20 is received. If this fails, the next step is to obtain the control word (control wave) ii— from the public base station 30 (step 106).

Next, it is checked whether or not a control signal (control wave) from the public base station 30 has been received (step 107). Here, the control signal (control wave) from the public base station 30 is determined. If the reception of the message fails, this process ends (step 110).

In step 103, a control signal (control wave) from the private base station 20 is received. If it is determined that the communication has succeeded, monitoring of the incoming call signal included in the control signal (control wave) from the private base station 20 is started (step 104). This state is a connection control state by the private base station connection control unit 482 of the control unit 48. After that, this process ends (step 1◦5).

Also, in step 107, when it is determined that the control signal (control wave) from the public base station 3◦ has been successfully received, the destination signal included in the control signal (control wave) from the public base station 3◦ is received. Start monitoring the word (step 108). This state is a connection control state by the public base station connection control section 481 of the control section 48. Thereafter, this processing ends (step 109).

If it is determined in step 101 that the incoming call test setting mode is set to the public call detection mode, the control signal (control wave) from the public base station 30 is first received. Attempt (steps 1 1 1).

Next, it is checked whether or not a control signal (control wave) from the public base station 30 has been received (step 112). Here, the control signal (control wave) from the public base station 3 ° is received. If unsuccessful, an attempt is made to receive a control signal (control wave) from the private base station 20 (step 115).

Next, it is determined whether or not a control signal (control wave) from the private base station 20 has been received (step 116). Here, the reception of the control signal (control wave) from the private base station 20 has failed. Then, this process ends (step 117).

If it is determined in step 112 that the control signal (control wave) from the public base station 30 has been successfully received, the incoming signal included in the control signal (control wave) from the public base station 3 ° is determined. Start monitoring (step 113). This state is a connection control state by the public base station connection control section 481 of the control section 48. After that, this process ends (step 114).

If it is determined in step 116 that the control signal (control wave) from the private base station 20 has been successfully received i, the control signal (control wave) from the private base station 20 is received.監視 Start monitoring the word (step 118). This state is a connection control state by the base station connection control section 482, which is operated by the control section 48 independently. After that, this processing ends (step 119). As described above, when the private call detection mode is set as the incoming call verification setting mode, first, an attempt is made to receive a control signal (control wave) from the private base station 2◦, and if that fails, Then, an attempt is made to receive a control signal (control wave) from the public base station 30. This processing is performed by receiving a control signal (control wave) from the private base station 20 or by using the public base station 30. Repeat until one of the control signals (control waves) is successfully received. Similarly, when the incoming call detection mode is set as the incoming call verification setting mode, first, an attempt is made to receive a control signal (control wave) from the public base station 30 and this fails. Then, next, an attempt is made to receive a control signal (control wave) from the private base station 20, and this processing is performed by receiving a control signal (control wave) from the public base station 30 or using the private base station 2. Repeat until one of the control signals (control waves) from 0 is successfully received.

By this processing, if the private call detection mode is set as the incoming call verification setting mode, when the portable communication terminal first enters the service area of the private base station 20, the control unit is given priority. The connection control state of the private base station connection control unit 48 is switched to the connection control state. For example, before the portable communication terminal enters the service area of the private base station 20, the public base station is connected. Upon entering the service area 30, the connection is automatically switched to the connection control state by the public base station connection control section 481 of the control section 48.

The connection is switched to the connection control state by the public base station connection control unit 481 of the control unit 48.For example, before the portable communication terminal device enters the service area of the public base station 30, the self-owned ffl base station Upon entering the service area of the station 20, the connection is automatically switched to the connection control state by the private base station connection control section 482 of the control section 48. That is, regardless of whether the incoming call verification setting mode is set to the private ringtone detection mode or the public call detection mode, this portable communication terminal device can be used as a private ffl base station 20 or a public ffl base station. When the vehicle enters the service area of 30 and becomes communicable via the private base station 20 or the public base station 30, the connection control state by the private base station connection control unit 4 82 or the public The connection is automatically switched to the connection control state by the base station connection control section 481, thereby receiving a call or a call via the 1: 1 management base station 20. It can respond to any incoming call through the public base station 30. By the way, in this embodiment, even if the mobile communication terminal device is within the service area of the private base station 2〇 and the connection is controlled by the private base station connection When the communication terminal device is in the service area of the public base station 3 ◦, the connection can be switched to the connection control state by the public base station connection control section 481.

When this process is started (step 120), the incoming call detection mode setting section 483 sets the incoming call detection setting mode to either the private use incoming call detection mode or the public incoming call detection mode. Find out if they are (steps 1 2 1). Here, when the private-use incoming call detection mode is set, there is no instruction to switch to the connection control state by the public base station connection control unit 481, so that the private base station connection control unit 48 The connection control state by 2 is continued, and this processing ends (step 1311).

If it is determined in step 122 that the incoming call verification setting mode is set to the public incoming ringing mode, the control signal (control wave) from the public base station 30 is first transmitted. Attempt to receive the message (steps 122).

Next, it is checked whether or not a control signal (control wave) from the public base station 30 has been received (step 123), and the control signal (control wave) from the public base station 30 is determined here. Upon successful reception of the control signal, monitoring of the incoming signal included in the control signal (control wave) from the public base station 30 is started (step 124). This state is a connection control state by the public base station connection control section 481 of the control section 48. Thereafter, this processing ends (step 125).

In addition, if it is determined in step 123 that the control signal from the public base station 30 has failed to be received i, the control signal from the private S base station 20 is determined. Control wave) Attempt to receive (step 126) o

Next, it is checked whether or not a control signal (control wave) from the private base station 2 ° has been received (step 127), and the reception of the control signal (control wave) from the private base station 20 has failed. If this is the case, the process ends (step 130).

In step 127, if the control signal (control wave) from the private base station 2 ° is successfully received, the monitoring of the incoming signal included in the control signal (control wave) from the private base station 20 is started. Yes (step 128). This state is a connection control state by the private base station connection control unit 482 of the control unit 48. Thereafter, this processing ends (step 129).

Also, in this embodiment, the portable communication terminal device is in the service area of the public base station 3J, and in the connection control state by the public base station connection control unit 481, the portable communication terminal If the device is within the service area of the private base station 30, the connection can be switched to the connection control state by the private base station connection control unit 482.

FIG. 5 is a flowchart showing a process of switching to the connection control state by the private base station connection control unit 482 when the portable communication terminal device is in the connection control state by the public base station connection control unit 481. is there.

When this process is started (step 140), the incoming call detection mode setting section 483 first sets the incoming call detection setting mode to either the private use incoming call detection mode or the public incoming call detection mode. Check whether it is set (step 141).

In a case where connection is possible, for example, even if the portable telephone terminal is set to switch to use the first base station, it is not within the service area of the first base station, and The base station within the service area of the base station can be automatically switched so as to be able to respond to an incoming call using the second base station.

Conversely, even if the portable call terminal is set to switch to use the second base station, it is not within the service area of the second base station and the service area of the first base station. It is possible to automatically switch and set the pedestal located within to be able to respond to the incoming call using the first base station.

Also, when the service area of the first base station and a part of the service area of the second base station overlap, this portable communication terminal uses the first base station. Even if the switch is set, the second base station will respond in response to ffl It is possible to make the switching setting so that it can be changed.

Conversely, even if this portable communication terminal device is set to switch to use the second base station, it can be set to switch from this state so that it can respond to an incoming call using the first base station. become.

Also, when a call is made from this portable communication terminal device, even if this portable communication terminal device is set to use the first base station or the second base station, It is possible to perform control so that a call is made using a base station having a higher priority set in advance among the one base station and the second base station. Industrial availability

As described above, according to the present invention, in a portable communication terminal device that can be switched and set to use at least one of two radio base stations and a control method thereof, any one of the radio base stations is used. Even if the switching is set to, when the switching is not within the service area of the set wireless base station, the control is automatically switched to control using another wireless base station, and the other wireless base station is used. It is possible for you to speak.

In addition, when at least the two wireless base stations are in the service area of both, the mobile terminal is automatically switched and set so as to be able to make a call using a predetermined wireless base station. This allows outgoing / incoming calls using a desired wireless base station. For example, in a portable communication terminal device that can be set to switch between a private base station and a public base station, if either the private base station or the public base station is used as the arrival detection mode, Even if the switching is set, when the portable telephone terminal is within the service area of the private base station, the portable telephone terminal uses the private base station, and when the portable terminal is within the service area of the public base station, Switching is automatically set so that incoming calls using a public base station are possible. This eliminates the need for the user to perform complicated setting operations for switching base stations.

If the mobile terminal is located in both the service area of the public base station and the service area of the private river base station, the user can select the public fflll local station and the private terminal. Incoming calls can be made using any of the base stations.
