Conventionally, packet switching equipment has been able to have multiple office numbers per station. For example, a switching equipment installed in Tokyo could accommodate not only terminal equipment in Tokyo, but also terminal equipment in Yokohama and Chiba, and at the same time accommodate different terminal equipment for each station. Give the station number and as if
It could be treated in the same way as if a packet switch had been installed in each area. In that case, a numerical analysis table is prepared for each station number to determine the correspondence between the numbers of all the terminal equipment accommodated in the packet switch and the actual line numbers, and one numeric analysis table is prepared for each station number to determine the correspondence between the numbers of all the terminal equipment accommodated in the packet switch and the actual line numbers. The terminal subscriber number contained in the packet was extracted, and a numeric analysis table for the corresponding station number was indexed to determine the outgoing line number. When a terminal device housed in such a packet switch is relocated to another packet switch due to expansion or scale expansion, it is preferable for the subscriber not to change the terminal subscriber number, including the accommodating station number. It is. Therefore, relocation was performed in units of station numbers by transferring a numerical analysis table prepared for each station number to the destination packet switch. In this case, in order to minimize service interruption during relocation, it is necessary to relocate terminal devices with the same station number simultaneously within a short period of time.

In the conventional terminal equipment relocation method described above, if the terminal equipment is not relocated at the same time within a short period of time, the terminal equipment with the same station number will be housed in two stations during the relocation, and the connection will be interrupted. It is conceivable that there will be calls that cannot be made. Therefore, there is a problem in such re-accommodation that it requires a large number of man-hours at once in order to prepare in advance and perform the re-accommodation work in a short time.

The terminal equipment installed in each of the source packet switch that relocates the multiple terminal devices previously housed in the local station to another station, and the destination packet switch to which the multiple terminal devices are relocated, For the terminal subscriber number, the relocation source packet switching equipment uses the route number of the trunk line to the relocation destination packet switching equipment, and the relocation destination packet switching equipment uses the relocation terminal accommodating line number of the relocated terminal equipment that has not yet been relocated. For terminal subscriber numbers of multiple terminal devices not related to the relocation, calls are made using a numeric analysis table dedicated to the relocated terminal that records unimplemented indications and the numeric analysis table dedicated to the relocated terminal. If the result of analyzing the called terminal subscriber number in the request packet indicates that it is not implemented, the call request packet is normally sent to the routing module. If the result of analysis is the route number of a relay line, that route number is relayed. A routing module dedicated to the relocated terminal transmits a call request packet to the line and, if the result of analysis is a line number accommodating the relocated terminal, transmits the incoming call packet to the terminal device of the corresponding line number. Routing method exclusively for relocated terminals.
