Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone call and multimedia communication system.

[Prior Art] There are mainly two types of terminals: a mobile call communication terminal having an IP mobile phone function, and a mobile call communication terminal having an IP mobile phone function and a general mobile phone function at the same time. A portable telephone communication terminal having an IP telephone function has the convenience of portability, and makes use of the speed of wireless LAN communication speed to enable a telephone call by packet conversion. The mobile phone communication terminal having both the IP phone function and the mobile phone function has further expanded the call range of the mobile phone and added high quality.

In addition to the full power mode (Active Mode) that can be received anytime during terminal standby, there are two techniques for terminal standby power control. One is a method in which, when the terminal is in the wireless LAN area, the access point throws a beacon at regular intervals to make the terminal communicable (Power Save Mode). The other is a method in which when the terminal is outside the wireless LAN area, the terminal basically checks whether there is an access point every predetermined time in the sleep state (Sleep Mode).

A technique for increasing the number of terminals that can be accessed simultaneously is a method in which packets at the same destination are collectively transmitted on the access point side, and data is transmitted quickly by shortening the waiting time on the terminal side.

Problems to be solved by the invention

The first problem is that there is no provision for controlling power between a mobile communication terminal having an IP telephone function and an access point or it is not yet sufficient. Since the terminal side does not know when there is an incoming call, in the active mode, when it is in the area, it can always be received while it is awake, but the standby time is shortened due to high power consumption. Therefore, since it is unsuitable for long-time use in a place where charging is inconvenient, convenience from the portability of the mobile phone is lowered. It is currently used only as an extension telephone on the premises.

In the case of Power Save Mode, when the terminal is in the wireless LAN area, power consumption is suppressed by repeating a low power consumption state and a full power state where communication is possible. However, since the full power state with high power consumption is frequently used, the effect is insufficient.

In the sleep mode, it is used when the terminal is outside the wireless LAN area, and it is checked whether the terminal has entered the wireless LAN area by using a timer of the terminal itself, so that the basic state is that little power is consumed. Therefore, although power can be effectively suppressed, there is a problem that the terminal cannot be intentionally started from the access point side.

The second problem is that cellular phone communication terminals having IP telephone functions use a wireless LAN, but the frequency band that can be used in the wireless LAN is narrow, so if a large number of access points are concentrated in a narrow area, interference occurs. End up. Since the installation density of access points is low, the number of terminals that can be accessed simultaneously is reduced. Therefore, the voice quality is likely to fluctuate, and the call is interrupted at the time of handover. Although there are methods such as improving the packet transmission method, the processing capacity is clearly inferior to that of the mobile phone base due to the scale of the access point equipment, so it is not a fundamental solution.

The third problem is that, unlike a general mobile phone, an IP mobile phone cannot currently be assigned a telephone number, and therefore cannot receive a call from a general subscriber phone or a mobile phone. A terminal equipped with a conventional mobile phone function and IP phone function in one mobile call communication terminal can access the mobile phone number of the other terminal when using the mobile phone call communication route, It can also be displayed. However, when using the IP call communication route, the access destination is not the phone number of the other party's mobile phone, but the ID of the IP mobile phone, and only the mutual ID can be displayed. For this reason, there is a disadvantage that the operation is more complicated than a conventional mobile phone and the convenience and recognizability are lacking.

Means for solving the problem

In order to solve the first problem, the system of the present invention has a function of a general mobile phone and a function of an IP phone using a wireless LAN in one mobile call communication terminal, and one of them is in an active state during standby. Exchange necessary information with mobile phone base or IP phone access point (AP), put the other side into sleep state, switch both states after a certain period of time, repeat it, and wait in time Means is provided for assigning more active states to those with less power consumption.

In order to solve the second problem described above, the system of the present invention has a function of a general mobile phone and a function of an IP phone using a wireless LAN in one mobile call communication terminal, and a priority route from both call communication routes. And a means of waiting for connection at the time of outgoing / incoming calls and during call communication.

In order to solve the third problem, the system of the present invention has a function of a general mobile phone and a function of an IP mobile phone using a wireless LAN in a single mobile call communication terminal and Regardless of the type, regardless of the type of the caller's caller ID display function, the mobile phone number of each terminal is displayed, and access can be made using only the mobile phone number of each other's terminal. It is characterized by providing a function.

[Operation] By providing the power control means, it is possible to keep a state of low power consumption for a long time when the terminal is on standby.

By providing means for waiting for call communication connection, it becomes possible to connect a plurality of routes, so that the connection is more reliable, and further, when the call sound quality deteriorates or the signal is weak, it is possible to connect to another route. Switching is more reliable and smooth. Therefore, the call quality is improved and the call is less likely to be interrupted during handover.

By providing the means for attempting the simultaneous connection of multiple routes, even if the IP mobile phone part of the waiting terminal is in the sleeve state, since the general mobile phone part in the terminal is in the active state, reception is possible. If a signal is received through a general mobile phone route, the IP mobile phone portion can be intentionally raised inside the terminal. Therefore, the connection of the priority route is ensured in a short time.

By providing a function for unifying the display and access means of the mobile phone and the IP mobile phone to the mobile phone number, the functions of the general mobile phone and the IP mobile phone can be operated in almost the same manner as a conventional general mobile phone. A terminal having functions can be operated at the same time.

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, an embodiment of the present invention will be described with reference to FIGS.

FIG. 1 shows a basic configuration example of the present invention. A receiving / transmitting device and an information processing device for an IP mobile phone using a general mobile phone and a wireless LAN are provided in one portable terminal. The terminal is connected to a general mobile phone base station or a wireless LAN access point (AP), and calls and communications are performed through the terminal.

FIG. 2 shows a configuration example of the power consumption control in the terminal standby mode according to the present invention. While the terminal is in a standby state, use either of the two communication routes to exchange information with the mobile phone base station or wireless LAN access point regarding whether or not it is within an area where reception and transmission can be performed. I do.

Since information communication between the terminal and the mobile phone base station consumes less power than information communication between the terminal and the access point (AP) of the wireless LAN, the information communication route between the terminal and the mobile phone base station is used as the main communication route. The information communication route between the terminal and the LAN AP is set as a sub route.

In both communication routes, one side is always in the active state and the other is in the sleep state, and the switching of both states is controlled. In order to reduce standby power consumption, the active state of the main communication route with low power consumption is allocated more in time. For example, main: sub is set to 9: 1.

The mobile phone base station registers and manages wireless LAN AP information within the area covered by the base station. Information indicating which mobile phone base station is within the area of the wireless LAN AP is registered and managed.

When the main communication route is used, the mobile phone base station can obtain information including the location of the terminal by checking information with the terminal. Based on this, it is possible to determine the superiority of the communication state between a plurality of wireless LAN APs that can cover the terminal and the wireless LAN AP and the terminal. The information is transmitted to the terminal using the main communication route in use. At the same time, each piece of information of the terminal is transmitted to a plurality of LAN APs that can cover the terminal.

By transmitting the above information, it is effective to smoothly establish sub-communication with a short time. At the time of sub-communication, the terminal confirms information with a plurality of wireless LAN APs that can cover the terminal based on the obtained information, and determines the possibility and superiority of the communication state with the plurality of wireless LAN APs. Check.

A description will be given of outgoing / incoming calls, telephone calls, and data communications of terminals in the present invention. First, a function is provided for setting one of a route using a mobile phone base station and a route using a wireless LAN as a priority route.

For example, when the wireless LAN route is set to a low charge, the low-charge wireless LAN route is usually given priority. However, when the communication state of the wireless LAN route becomes unstable, the non-priority mobile phone base station route is automatically set. An automatic mode for switching automatically is provided. Then, if the user himself / herself wants to maintain call communication quality during high-speed movement or in areas where there are many obstacles, the mobile phone base station route is the preferred route, data downloads such as data downloads, and usage charges. When it is desired to suppress this, a manual setting mode in which the wireless LAN route can be set as a priority route is provided.

FIG. 3 shows a configuration example of a mechanism for transmitting and receiving between terminals of the same type as described above when the wireless LAN route is set as a priority route. In order to ensure reliable connection between terminals, if priority and non-priority routes are available when making and receiving calls between terminals, not only priority routes but also non-priority routes can be used simultaneously. Try to connect.

When the connection of the priority route is established first, the connection of the priority route is executed in order from the highest priority to perform a call and communication. If the connection of the non-priority route is established first, the connection is not executed, but the connection is kept waiting. Within a certain time, it waits for the establishment of the priority route connection. If the connection of the priority route is established within the time, the connection of the priority route is executed. If the connection of the priority route within the time cannot be established, the waiting state of the established non-priority route is released and the connection of the non-priority route is executed.

FIG. 4 shows a configuration example of a mechanism during a call and during communication between terminals of the same type as described above when the wireless LAN route is set as a priority route. In order to improve the call and communication quality between terminals and reduce the phenomenon that the call is interrupted when a handover is performed, a connection waiting state for a plurality of other routes is created in addition to the route being used.

For example, when the connection of the priority route is established and the connection is executed, in addition to the route being used, connection of a plurality of priority routes and non-priority routes is attempted, and among them, the connection of several established routes is awaited Keep on.

When the connection status of the route being used becomes poor, for example, the number of accesses to the AP of the LAN being used increases, the data communication speed decreases, or the connection status becomes unstable due to movement of the terminal In such a case, before the call and communication are interrupted, the waiting route is released from the descending order of priority, the connection is executed, and switching to the use of a new connection route is performed.

An access function between terminals of the same type will be described. A function for automatically recognizing the mobile phone number of the same terminal and the ID of the mobile IP phone in order to improve the display recognizability and the convenience of operation of the access method. A function for simultaneously using the LAN route, and an information management function for converting packet information containing the ID information of the transmitting terminal at the time of reception into mobile phone information of the transmitting terminal are provided.

By simply dialing the other party's mobile phone number or accessing the other party's mobile phone mail address, not only the route that the calling terminal uses the mobile phone base station, but also the wireless LAN automatically Attempt to connect to the other terminal through the route to be used, and execute the connection from the priority order.

When connection to the terminal on the receiving side becomes possible, regardless of whether the connection is executed or waiting for connection, the mobile phone route information is received for the mobile phone route, and the IP mobile phone ID information is received for the wireless LAN route. To your device.

When the receiving terminal receives the mobile phone number information, the mobile phone number of the calling terminal is displayed as before. When the ID information of the calling terminal is received but the mobile phone number information cannot be received or the reception is delayed, the packet information conversion function of the terminal converts the ID information of the IP mobile phone of the calling terminal, The mobile phone number of the calling side terminal is displayed on the display panel of the receiving side terminal instead of the information that can recognize the mobile phone number of the calling side terminal.

When the terminal receives from a terminal that does not have an IP function, or when the terminal makes a call to a terminal that does not have an IP function, the wireless LAN route cannot be used, so the conventional access method and display method can be used.

The invention's effect

Since the standby power control means can maintain a state with low power consumption for a long time, the power consumption during the standby state of the terminal can be significantly reduced. Since it can be used for a long time even in places where charging is inconvenient, the advantage of portability of the portable terminal can be further utilized.

Since the number of routes to be established is increased by providing means for waiting for call communication connection, reliable connection establishment and stable call communication can be maintained without increasing the number of access points in the area.

By providing a function for unifying display and access means to the mobile phone number, the terminal can be recognized and accessed by the mobile phone number as before. In addition, by greatly reducing the complicated operation methods unique to IP mobile phones, the terminal can be operated with little new knowledge.
