When the connection between the caller communication terminal 1 1 0 and the communication terminal 1 2 0 used by the callee is completed, communication is started between the two communication terminals (step S 3 0 5).

On the other hand, when it is confirmed that there is no response from the called party or that the answer has been rejected by the called party (step S 3 0 4), the communication application returns to the state before the designation of the called party. .

Next, the operation for controlling the call of communication terminal 120 according to the present embodiment will be described.

FIG. 4 is a flowchart for explaining the operation for controlling the call of communication terminal 120 according to the present embodiment. In the following description, reference will be made to the required parts of Figure 1 as necessary.

Before starting system operation, the system administrator designated by the provider providing the communication service uses the call management means 1 0 1 of the server 10 to identify the communication terminal 1 2 0 of the provider providing the communication service. Register in advance. Further, the identification information of the mobile terminal 50 carried by the user who uses the communication system is similarly pre-registered. Here, the identification information of the communication terminal 120 or the mobile terminal 50 includes telephone number data, network address data, and individual identification number data that can uniquely identify the terminal. In addition, metadata (for example, latitude data, longitude data, altitude data, address data, etc.) indicating the location of the communication terminal is pre-registered as ancillary information of the communication terminal identification information. Referring to FIG. 4, first, the call management means 1 0 1 provided in the server 10 receives a call request from the caller's communication terminal 1 1 0 (step S 4 0 1).

The call request includes callee information. The called party information is identification information of the mobile terminal 50 carried by the called party, and includes telephone number data, network address data, and individual identification number data that can uniquely identify the mobile terminal 50.

When the call management means 10 0 1 receives the call request, it checks whether the called party information included in the call request is pre-registered in the server 10 (step S 4 0 2). If the call management means 10 01 determines that the called party information included in the call request is not pre-registered, it proceeds to the operation of step S 4 16 (step S 4 0 3). When the caller information is pre-registered, if the ID that identifies the called party in addition to the identification information of the mobile terminal 50 carried by the called party is also registered, in step S 4 0 1 , The called party's own ID may be used as the called party information.

In this case, in step S 4 0 2, the call management means 1 0 1 can also search for identification information of the mobile terminal 50 pre-registered with the ID of the called party included in the call request.

When it is confirmed in step S 4 0 3 that the specified called party information has already been registered in advance (step S 4 0 3), the call management means 1 0 1 The callee information is provided. The location status detecting means 10 2 causes the location information providing server 1 40 to search for location information of the mobile terminal 50 corresponding to the called party information (step S 4 0 4).

If the location information providing server 1 4 0 can determine the location of the mobile terminal 50 (step S 4 0 5), the location status detection means 1 0 2 sends the corresponding movement from the location information providing server 1 4 0. The current location information of the terminal 50 is acquired (step S 4 0 6). Here, the position information is composed of either a combination of latitude data and longitude data or a combination of latitude data and longitude data.

If the location of the corresponding mobile terminal 50 cannot be determined in step S 4 0 4 (step S 4 0 5), the location status detection means 1 0 2 receives the location information via the location information providing server 1 4 0. Inquires the caller's mobile terminal 50 about detailed current location information. In this case, the mail function of the mobile terminal 50 is used.

For example, if you are on the 5th floor of a building where the called party is located and the location parameters provided by the location information provision server 14 0 are only latitude and longitude parameters, the caller will move. Ask terminal 50 about the floor of the building. The called party responds by email to the inquiry. It should be noted that the reply of the e-mail shall be made in a format that allows the position status detection means 1 0 2 to analyze the position information from the e-mail in order to determine the exact position by the position situation detection means 1 0 2.

The location status detection means 1 0 2 determines the exact location of the called party, and organizes the search results of communication terminals that can be used by the called party based on the determined location.

If the caller's mobile terminal 50 is queried for detailed current location information, but the caller's exact location cannot be determined, the call management means 1 0 1 has failed to call. A response result indicating that is sent to the caller's communication terminal 1 1 0 (step S 4 1 6).

Next, the flow after the current location information of the mobile terminal 50 is acquired in step S 40 6 will be described.

Location status detection means 1 0 2 provides location information of mobile terminal 50 to incoming terminal search means 1 0 3

To do. Receiving terminal search means 1 0 3 is based on the location information of the mobile terminal 50 corresponding to the called party information, and from the pre-registered communication terminal information, the location of the corresponding mobile terminal 5 0 The terminal information of the communication terminal 1 2 0 installed in the vicinity is acquired (step S 4 0 7).

In step S 40 07, a flexible search can be performed by setting a search policy for searching for an appropriate communication terminal according to the caller's situation. For example, set a search policy that determines whether to narrow down the communication terminals to be searched according to the length of the call waiting time. The search policy is set by the caller. 'If the caller has specified that the call waiting time should be shortened, the communication terminal installed closest to the caller's mobile terminal 50 is searched. In addition, if it is specified that the call waiting time is not specified (the waiting time may be long), a communication terminal installed within several hundred meters from the location of the mobile terminal 50 of the called party is selected. Search for. The search policy data is stored in the data base 1 0 5 by the call management means 1 0 1 or the receiving terminal search means 1 0 3.

The called party can use a communication terminal that satisfies the above search policy and is not currently in use.

The called terminal searching means 1 0 3 checks whether or not there is a communication terminal 1 2 0 that can be used by the called party (step S 4 0 8). ,

If the terminal information of the communication terminal 120 that can be used by the called party is not obtained, the operation proceeds to step S 4 16 (step S .4 0 9).

When the communication terminal 1 2 0 used by the called party is determined in step S 4 0 9, the incoming terminal search means 1 0 3 calls the called terminal's mobile terminal 5 0 from the calling party. Information that there is a request and a response request are transmitted (step S 4 1 0).

For response requests, install a communication terminal 1 2 0 used by the called party to respond to the call. Contains location information.

FIG. 12 is a flowchart for explaining the operation of the communication system until the calling party calls the called party according to this embodiment. In the following description, reference will be made to the required parts of Figure 8 as necessary.

The caller is the application program installed on the communication terminal 2 1 0. Log into Ram 2 1 2 by entering the caller's user name and specify the caller's user name and search criteria. Here, the user name of the called party and the search condition are used as the called party information. The called party information is identification information of the IP telephone 2 30 carried by the called party. FIG. 13 is a diagram showing an example of a screen for setting a calling condition from the communication terminal 210 according to the present embodiment.

The calling party designates the user name and search condition of the called party on the call setting screen 400. In this operation example, “y a m a d a” is set as the user name, “Urgent” is set as the search condition, and the button displaying “Call” is pressed. As a result, a call request is made by the caller.

The call request includes caller information and callee information. The caller information includes the caller's user name data and the IP address data of the communication terminal 2 10.

Referring to FIG. 12, the call request input by the caller is transmitted to the server 30 via the network strength 2 1 1 of the communication terminal 2 1 0 (step S 1 2 0 1). . When the call management means 1 0 1 of the server 30 receives the call request, the user name data of the called party is stored in the database 1 0 7. It is confirmed whether it is registered in the data of the name 3 1 1 (step S 1 2 0 2).

If the user name of the called party included in the received called party information is registered as IP phone identification information 3 1 0 in the device 1 0 7 (step S 1 2 0 3 ), The call management means 1 0 1 acquires the data of the telephone number 3 1 2 of the called party (step S 1 2 0 4).

If the call management means 1 0 1 searches the database 1 0 7 based on the caller information specified by the caller, but the user name of the callee is not registered Will be described later.

The call management means 1 0 1 provides the acquired telephone number 3 1 2, the called party information, and the calling party information to the location status detection means 1 0 2.

The position status detection means 1 0 2 requests the position information providing server 1 60 to search for the position information of the IP telephone 2 3 0 corresponding to the telephone number (step S 1 2 0 5). In-house, the called party always carries the IP phone 2 3 0, and the location information transmission device 2 3 2 of the IP phone 2 3 0 periodically sends radio waves to the location information providing server 1 6 0. is doing.

The location information providing server 160 identifies the location of each IP phone based on the strength (field strength) and direction of the radio wave received from each IP phone, and stores the latest location information of each IP phone in a memory or the like. It is recorded on a medium (not shown). A plurality of location information providing servers 160 may be installed. In this operation example, the case where the location information of the IP phone is composed of latitude data, longitude data, and altitude data will be described. When the position information search device 1 6 2 receives a position information search request for the IP telephone 2 3 0 from the position status detection means 1 0 2, the position information providing server 1 6 0 It searches the information recorded in the server and notifies the server 30 of the position status detection means 10 02 (step S 1 2 0 6).

The location information providing server 160 receives the latest location information of the corresponding IP phone 2 3 0 after receiving the location information search request for the IP phone 2 3 0 from the location status detection means 1 0 2. It is also possible to notify the position status detection means 1 0 2.

When the location information detecting means 1 0 2 obtains the location information of the IP telephone 2 3 0 from the location information providing server 1 6 0, the location status detection means 1 0 2 and the call management means 1 0 1 obtain the location information. The caller information and the callee information are provided to the callee terminal search means 10.3.

The called terminal search means 1 0 3 is the latitude 3 0 of the communication terminal registered in the database 1 0 7 based on the location information of the IP phone 2 3 0 received from the location status detection means 1 0 2. 3. Compare with the data of longitude 3 0 4 and altitude 3 0 5 and search for communication terminals satisfying the search condition 3 2 1 included in the callee information (step S 1 2 0 7).

In this operation example, search condition 3 2 1 is “urgent”, so search policy information with search policy information 3 1 0 registered in database 1 0 7 is “urgent” is searched. The search range of the search policy information 3 2 0 is acquired.

As shown in Fig. 1 1. Search policy 3 2 1 registered as “urgent” Search policy information 3 2 0 search range 3 2 2 is “minimum”, so called terminal search Means 1 0 3 finds a communication terminal 2 2 0 close to the location of IP telephone 2 3 0 (step S 1208

There are multiple communication terminals 220 and 225, but here the communication terminal 220

1 It will be described as being close to the position of the P telephone 230.

In addition, when the callee terminal search means 103 cannot find the communication terminal 220 that meets the search condition 32 1 designated by the caller (step S 1208), this will be described later.

The called terminal search means 103 obtains the data of the IP address 301, the machine name 302 and the installation location 306 of the communication terminal 220 from the database 107, and the data of the machine name 302 and the installation location 306 and the position status detection means. A response request including the caller information obtained from 102 is transmitted to IP telephone 230 (step S 1

209).

When the callee receives a response request from the IP telephone 230, the display (not shown) attached to the IP telephone 230 has a call from the caller and the communication terminal 220 used to answer the call. Information is displayed.

FIG. 14 is an example of a response request displayed on the screen of the IP telephone 230 according to the present embodiment. In the response request, the data of the machine name 302 and the installation location 306 of the communication terminal 22 Q are displayed. The called party looks at the response request screen 500 and presses the “OK” button (step S 12 1 1) when answering the call (step S 1210). When the called party answers the response request through the IP telephone 230, the response result is notified to the called party terminal searching means 103 of the server 30 (step S 1212).

If the called party does not answer the call by looking at the response request screen 500 (step S 1210), the “cancel” button is pressed (step S 1211).

The called party terminal search means 103 passes the received response result and the data of the IP address 301 of the communication terminal 220 acquired from the database 107 to the incoming terminal control means 104.

The incoming terminal control means 104 confirms that the call has been successful from the response result received from the called party terminal searching means 103, and the IP address 301 of the communication terminal 220 received from the called party terminal searching means 103. Based on the data, it connects to the communication terminal 220 via the network card 106¾. In addition, incoming server 30 The terminal control means 10 4 transmits a command for remotely starting the application program 2 2 2 installed in the communication terminal 2 2 0 to the communication terminal 2 2 0 (step S 1 2 1 3).

The communication terminal 2 2 0 receives the start command of the application program 2 2 2 via the network card 2 2 1 and executes it (step S 1 2 1 4). On the other hand, the called party searches for the communication terminal 2 20 installed in the company based on the terminal information presented on the response request screen 500. A tag with the machine name is affixed to the communication terminal 2 20, so if several terminals are installed near the installation location shown, you can search using the tag.

Since the application program 2 2 2 has already been activated in the communication terminal 2 2 0, the callee inputs his / her user name and logs in to the application program 2 2 2. Then, the connection between the communication terminal 2 2 0 and the caller's communication terminal 2 1 0 is established, and multimedia communication is started (step S 1 2 1 5). When the call management means 1 0 1 searches the database 1 0 7 based on the called party information specified by the calling party, the user name of the corresponding called party does not exist (step S 1 2 0 3), or when the caller terminal search means 1 0 3 cannot find the communication terminal 2 2 0 that matches the search condition specified by the caller (step S 1 2 0 8), or when a response to reject the call is received from the caller's IP telephone 2 3 0 (step S 1 2 1 1), in either case, the callee terminal of the server 3 0 A search result indicating that the call has failed is transmitted from the search means 1 0 3 to the caller's communication terminal 2 1 0 (step S 1 2 1 6).

The application program 2 1 2 that receives the response result from the server 30 displays a message of the response result on the display (not shown) attached to the communication terminal 2 1 0.

In the above embodiment, an example in which multimedia communication is performed between a calling party and a called party is described. However, this embodiment is also applied to communication using a communication method other than multimedia communication. Needless to say, it can be applied to the above.

According to this embodiment, an incoming call in which a caller moves within an organization such as a company, a store, or a school. The called party can use the communication terminal 220 to perform multimedia communication with the calling party.

The reason for this is that the IP phone 2 3 0 that is always carried by the called party is used to determine the position of the called party that moves dynamically, and the communication terminal used by the called party 2 2 0, 2 2 5 This is to search automatically.

The server 30 of the semiconductor integrated circuit according to the present invention can be realized in software by executing the communication control program 35 for executing the above-described means on the server 30 which is a computer processing device.
