It is determined whether or not the connection to the SIP server is possible (S101 and S102).
- step S102 if a reply signal is acquired, it is determined that communication can be continued with the current registration contents, and the current state is maintained and line monitoring is continued ("N" in S102). ) If the return signal is not acquired, it is determined that the connection state of the line has changed (“Y" in S102), the process proceeds to step S103, and connection to the IP network 4 is possible (broadband connection). It is possible to continue).
- step S103 When it is determined in step S103 that IP connection is possible ("Y" in S103), registration update is started as an IP line (IP phone number such as "050" is available) (S104). ). First, make a call to IVR8 on PSTN5 and connect to IVR8.
- the IVR8 stores the terminal information
- the connection information acquired from the unit 13 and the information acquisition unit 82 is transmitted to the change registration unit 72 of the registrar system 7 (S107 and S201a). At this time, if the user moves within the same service, for example, the IP phone number can be searched based only on the terminal identifier such as the MAC address, so transmission / reception of unnecessary information is omitted.
- step S105 voice response by the IVR 8 is started by calling the IVR 8, and necessary information is obtained by dial push or voice utterance according to the voice correspondence. Transmit to the IVR 8 (S106 and S201b).
- all the terminal information is not entered, but only the user ID, password, and IP number are entered, for example, the registrar system 7 or location Sano 3 using the user, password, etc.
- Other information (MAC address etc.) may be obtained by making an inquiry to the server!
- step S103 if it is determined in step S103 that IP connection is not possible (“N" in S103), registration update is performed as a public line (only 0AB to J numbers can be used) (S108). That is, a call is made to the IVR8 on the PSTN5, connected to the IVR8, and the user selects whether to use the automatic update function provided in the telephone terminal la or manual operation by the user (S109).
- automatic update (“Y” in S109)
- the connection information acquired by the terminal information storage unit 13 and the information acquisition unit 82 is transmitted from the IVR 8 to the change registration unit 72 of the registrar system 7 (S110 and S202a). ).
- necessary information is transmitted by dial push or voice utterance according to voice correspondence (SI 11 and S202b).
- the IVR 8 reports to the registrar system 7 the change in the connection information of the destination acquired in this way, and the registrar system 7 responds to this report by the user of the location server 3.
- One management database 3a is updated (S301, S302 and S401). In other words, when an IP phone is available at the destination, the destination public telephone number and the terminal identifier such as the MAC address are updated and registered, and when the IP phone cannot be used at the destination, Only the destination public telephone number is registered, and other terminal identifiers necessary for IP telephones are deleted.
- a call is made to the IVR 8 on the PSTN 5 and connected to the IVR 8 (S501). Then, according to the guidance of IVR 8, necessary information is transmitted by dial push or voice utterance (S502). In this manual update, you do not have to enter all the terminal information, for example, just enter the user ID, password, and IP number.
- the public line telephone number that is currently used by the user X is acquired using, for example, a number notification service, and the acquired telephone number is notified to the registrar system 7. (S601). If the destination public line does not provide the number notification service, the user manually inputs the telephone number of the public line and sends it.
- the registrar system 7 uses the user ID, password, IP number, and public line telephone number obtained in this way, and the corresponding SIP server (the SIP server to which user X belonged at the source). To obtain other information (MAC address, IP address, etc.). At this time, if the IP phone cannot be used at the destination, connection information for the IP phone is not acquired and only the destination public line telephone number becomes the connection information.
- the registrar system 7 Using the connection information of the destination acquired in this way, the registrar system 7 -Update the user management database 3a of the server 3 (S701, S702 and S801).
- the public telephone number of the destination and a terminal identifier such as a MAC address are updated and registered, and when the IP phone is not available at the destination, the mobile phone Only the previous public telephone number is registered, and other terminal identifiers necessary for IP telephone are deleted.
- FIG. 7 is a flowchart showing a procedure for making a call to the user X at the movement destination.
- a case where a call is made from user Y who can use an IP phone will be described.
- the user Y makes a call to the user X (S901).
- user Y makes a call with the IP phone number ("050-xxx-xxxx") that user X used at the source.
- This call processing is transmitted to the SIP server 6c to which the user Y belongs, and the connection exchange is started in the SIP server 6c.
- the SIP server 6c first, it is determined whether or not the user X is in the same network as the user Y (or in the same service by the same communication company) (S902). If both user X and user Y are in the same service ("Y" in step S902), normal connection processing is performed using only the connection information held by the SIP server 6c (S908). .
- SIP server 6c makes an inquiry to location Sano 3 (S903).
- Server 6c sends the IP phone number ("05 0-xxx-xxxx") of user X called by user Y to location server 3, and is linked to the IP phone number ("050-xxx-xxxx").
- Other connection information is acquired (S904).
- this SIP server 6c analyzes the acquired connection information and selects a connection method (S905). Specifically, it is determined whether or not the line to which User X moves can use the IP phone. That is, the connection information acquired in step S904 is only the destination public line telephone number ("Oab-xxx-xxxx"), and other information necessary for the IP phone (for example, MAC address and IP address). Is not connected, connect to the public network (S909). Select ("N" in step S905).
- connection information acquired in step S904 is the destination public line telephone number ("Oab-xxx-xxxx") and other information necessary for the IP telephone associated therewith. Sometimes this information is used to select a connection to the IP network ("Y" in step S905).
- Y When connecting to this IP network, user X can only connect via another SIP server, so connect to the relevant SIP server (S906) and establish communication. With the above procedure, a call with the destination user X is started (S907).
- connection information public line telephone number, IP telephone number, terminal identifier
