Description

  The present invention relates to a message delivery system, a server device, and a message delivery method for delivering a short message and an instant message between incompatible networks via an IP network.

Conventionally, communication is performed between incompatible networks, for example, between an IMT-2000 network and a PDC network by transmitting and receiving short messages (hereinafter referred to as SM) and instant messages (hereinafter referred to as IM). For example, when SM message delivery is performed, since the SM format is different in each mobile network (incompatibility), it is necessary to convert the SM format to a format suitable for each network, and the conversion is performed. As a device, a short message gateway that is a device using a specific protocol is installed to transmit and receive SM (for example, refer to Patent Documents 1, 2, and 3). This short message gateway is an expensive device because of its unique device.

Communication costs and gateway installation costs can be reduced.

  Furthermore, since the distribution server can perform mutual conversion between a mail address for an IP network (for example: xxx@yy.ne.jp) and a telephone number, incompatibility connected via an IP network such as the Internet. When the SM is distributed between networks having different characteristics, not only the mail address for the IP network as the destination / source, but also the address of the destination / source can be distributed to the user by specifying the telephone number.

  The best mode for carrying out the present invention will be described below in detail with reference to the accompanying drawings.

(Characteristics of the invention)
In the present invention, when SM or IM distribution is performed between incompatible mobile networks, the conventional No. 1 is used. A distribution server that can distribute SM received from the SMSC to the IP network without using a short message gateway that uses a special protocol on a common line signal is installed in front of the IP network of a different SMSC. As a result, the SM is set to No. No special protocol on the common line signal is converted to a protocol suitable for the IP network. 7 Communication can be performed using an IP network without using a common line signal.
Further, conventionally, the SM from the mobile network via the Internet cannot be distributed if the destination is designated by a telephone number. However, the present invention is not limited to the IP network mail address (for example: xxx @ yy.) Held in the distribution server. ne.jp) and a database in which telephone numbers are associated with each other, mutual conversion is performed, and even when a terminal is transmitted to a destination of a different mobile network by specifying a telephone number, the destination telephone is transmitted by the transmission server of the transmission source. When the SM is distributed between incompatible mobile networks by converting the number into an Internet e-mail address, and by converting the e-mail address into a telephone number at the receiving distribution server, The destination / source is not only the email address for the IP network, but also the address of the destination / source Scan can be the delivery is carried out in the phone number specified.
