Abstract:
1. A TCP/IP mobile communication network transmission and reception system for conducting transmission from a TCP/IP communication network to a mobile communication network, comprising: a provider access server for the connection of a TCP/IP communication network to receive an IP packet in which an IP address of a mobile communication terminal as a destination of transmission from the TCP/IP communication network is stored at a header; and a mobile communication switching system for extracting an IP address from a header of an IP packet sent from the provider access server and searching for a user's telephone number corresponding to the IP address to send an originating signal and a selection signal based on the searched user's telephone number to a mobile communication network on a side of said mobile communication terminal wherein said mobile communication switching system including a time-division switch for conducting time-division switching of line switching, a provider connection interworking function device for extracting said IP address of the mobile communication terminal as a transmission destination stored in the IP packet sent from the provider access server and searching for said user's telephone number corresponding to the IP address to output said selection signal and said originating signal based on the searched user's telephone number, an originating signal detection circuit for detecting said originating signal from the provider connection interworking function device, a selection signal reception circuit for receiving said selection signal from the provider connection interworking function device, and a calling processing device for executing control to send said originating signal from said originating signal detection circuit and said selection signal from said selection signal reception circuit to the mobile communication network on the side of said mobile communication terminal.
