Abstract

PURPOSE:To enable a user of a calling-side terminal to select a desired repeating network by providing, for example, a route table in an exchange node as the route information of repeating networks which can be connected from the exchange node and informing the calling-side terminal of the connectable repeating network selecting information. CONSTITUTION:A user dials the telephone number alpha of a called-side mobile terminal 112 from a calling-side terminal 111. Upon receiving the telephone number alpha, a calling-side exchange node 121 performs access to a data base 141 based on the telephone number and acquires the positional information of the position where the terminal 112 actually exists, such as the number of a called-side exchange node 122. The terminal 112 always registers its moving position in the data base 141. Then the calling-side exchange node 121 searches a route table 151 for connectible repeating networks and, upon finding the connectible networks, sends the number and charge information of each repeating network to the calling-side terminal 111. Upon receiving the signals, the terminal 111 displays the signals on a displaying section and the user selects one network and sends the selecting code of the selected network to the calling- side exchange node 121.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a communication route selection method in mobile communications in which a relay route desired by a user is selected from among a plurality of relay networks. (Prior art) At present, there are many relay network operators and distributors in the general telephone network, especially the relay network, and they provide different relay networks at different prices, and the users can receive only one call from the terminal. An inexpensive relay network is selected for the route in an effort to reduce communication charges. Calling side terminal power＼
If the network is fixed, the user of the calling terminal can recognize the switching node where the called terminal is accommodated from the telephone number of the called terminal, so it is economical to choose a relay network with You can tell from the phone number. That is, the user of the calling terminal first adds, for example, 0OAB as relay network selection information, dials the called terminal number, and selects the relay network and relay route based on 00AB at the switching node.

(Problem to be solved by the invention) However, in the case of a called terminal or a mobile terminal, the user of the calling terminal cannot tell from the telephone number of the called mobile terminal the switching node where the called mobile terminal is located. A problem arises in that it is unclear which relay network to select when dialing the relay network selection information.

The present invention enables the user of the calling terminal to select a relay route for a call based on an algorithm desired by the user of the calling terminal, even if the user of the calling terminal does not know whether the calling terminal is at an exchange node. It is an object of the present invention to provide a communication route selection method that enables economical communication in mobile communication in which at least one of the terminal and the receiving terminal is a mobile terminal.

(Means for Solving the Problems) In order to achieve the above object, the present invention has, for example, a route table as route information of relay networks connectable from the exchange node in a switching node, and By notifying the selection information to the originating terminal, the user of the originating terminal can select the desired relay network.

(Example) Embodiments of the present invention will be described in detail below with reference to the drawings.

I will clarify.

FIG. 1 shows an embodiment of the present invention, in which 111.112 is a terminal,
121, 122, 123 are exchange nodes, 13m 13
2, 133, and 134 are relay networks ① to ①, +41 is a database, and 151 is a route table.

When attempting to receive a call from the calling terminal 111 to the user or mobile terminal 112, the user dials the telephone number α of the receiving mobile terminal 112 from the calling terminal 111. The originating switching node +21 that received this sends the incoming telephone number α
Based on this, the database 141 is accessed to obtain location information on the actual location of the mobile terminal 112, for example, the number of the called switching node 122. Database 14
1, the location to which the mobile terminal 112 has always moved is registered. Next, the originating switching node 121 indexes the route table 151 based on this location information. An example of the configuration of the route table 151 is shown in FIG. Assuming that the number of the destination switching node is used as the location information, and if that number is X2X2, index the X2X2 column of the route table 151 and find out whether it is a connectable relay network or AB, CD, EF. When the terminal 111 learns of this number, it sends this number and charge information for each relay network to the originating terminal 111. In FIG. 2, the fee information is expressed as the number of seconds of talk per 1 degree yen. In other words, the relay network of selection code AB has switching node X2X2, 10.5 seconds/10
means a circle. When the originating terminal l11 receives this signal, it displays it on the display section.

If there is no display unit on the originating terminal 111, the originating switching node 121 may notify the user by voice. The user of the originating terminal 11 sees this display and sends the selection code of the desired relay network to the originating exchange node 121. In this example, if the user attempts to select a relay network with a lower fee, he or she will dial code AB. The originating switching node 121 sees the code AB and switches to the relay network I (131
), and transmits the number X2X2 of the destination switching node 122 and the number α of the mobile terminal 112 to the relay network I (131).
And if necessary, a relay network selection code AB is also sent. The relay network I (i31) sets up a line to the receiving switching node 122 and sends out the number α of the receiving mobile terminal 112. The terminating exchange y'l" 122 calls the mobile terminal 112 and
It is possible to communicate with the originating terminal Ill. Whether the notification from the originating switching node 121 is a voice or a signal can be easily identified by adding a special number when first transmitting the number α of the receiving mobile terminal 112. . In addition, the relay network selection code selected by the user sent from the originating terminal 111 is not used, but multiple codes are assigned priorities, and if connection is not possible due to all calls etc. to the relay network of the first priority, the It is also possible to use a relay network with two ranks. The control flow at the originating switching node is shown in FIG.

The signal sequence between the originating terminal 111 and the originating switching node 121 is as described above: first, the number α of the terminating mobile terminal 112 is sent, and then the originating switching node 1
It is preferable to receive the number of the terminating switching node from 21 or the own switching node number together with the number, and then transmit the relay network selection code, or to reduce the amount of signal. However, in the case of general fixed terminal-to-fixed terminal -\ communication, a relay network selection code and the number α of the called terminal are usually sent together. To match this signal,
When transmitting one relay network selection code from the originating terminal 111, the number α of the receiving terminal 112 may be transmitted together with AB again. This has the advantage of slightly increasing the amount of signals, or of being able to use the fixed communication processing for the processing of the switching node on the sender and sender side.

(Effects of the Invention) As described above, according to the present invention, it is possible for the user to select the relay network desired by the user even when making/receiving calls at a mobile terminal, and the optimum relay network is selected for each call for communication. Is it possible to do this?

Further, the present invention also applies when the originating terminal is a mobile terminal.
Since no special memory or equipment is required for the sending terminal, it has the advantage of being economically viable.
