- the MME 320A that has received the CSFB location registration request signal performs location registration in the 3.9G network 300 with respect to the subscriber accommodation station 400 in which subscriber information including location registration information and contract information of each mobile communication terminal is stored.
- Request (S002 in FIG. 1).
- the subscriber accommodation station 400 that has received the location registration request performs location registration in the 3.9G network 300, and then transmits subscriber information such as contract information of the mobile communication terminal 100 that has requested location registration to the MME 320A. (S002 in FIG. 1).
- subscriber information such as contract information of the mobile communication terminal 100 that has requested location registration to the MME 320A.
- S002 in FIG. 1 an E-UTRAN line identifier (S-TMSI) is generated by the MME 320A and included in a response signal described later.
- S-TMSI E-UTRAN line identifier
- the MME 320A that has received the CSFB location registration request signal also requests location registration from the MSC / VLR 220A via the line 500 (S003 in FIG. 1).
- the MSC / VLR 220A requests the subscriber accommodation station 400 to perform location registration in the 2G / 3G network 200 (S004 in FIG. 1).
- the subscriber accommodation station 400 performs location registration in the 2G / 3G network 200, and then sends subscriber information such as contract information of the mobile communication terminal 100 that has requested location registration to the MSC / VLR 220A. (S004 in FIG. 1).
- a UTRAN or GERAN line identifier (TMSI, CS-IMSI) is generated by the MSC / VLR 220A.
- the MSC / VLR 220A that has generated the line identifier transmits a location registration response signal in the 2G / 3G network 200 of the mobile communication terminal 100 to the MME 320A through the line 500 (S005 in FIG. 1).
- This response signal includes UTRAN and GERAN line identifiers (TMSI, CS-IMSI) by the MSC / VLR 220A, and the location registration in the 2G / 3G network 200 is completed by including this line identifier. It is shown.
- the MME 320A receives a location registration response signal including both the E-UTRAN channel identifier generated in response to the location registration in step S002 and the UTRAN and GERAN channel identifiers acquired in step S005. Generate. Then, the MME 320A transmits the location registration response signal to the mobile communication terminal 100 (S006 in FIG. 1). Thereby, the mobile communication terminal 100 that can receive the notification information from both the mobile communication networks 200 and 300 is set to be in the both mobile communication networks 200 and 300, and the mobile communication network such as CSFB is switched. It can be performed.
- the mobile communication system 1 that does not support CSFB does not have a function of making the location registration information of mobile communication terminals located in both mobile communication networks 200 and 300 correspond to each other through a line 500. Except for this point, it has the same configuration as the CSFB-compatible mobile communication system 1A.
- the 2G / 3G network 200 and the 3.9G network 300 form independent mobile communication networks due to the absence of such location registration information support function.
- a procedure in which the CSFB-compatible mobile communication terminal 100 performs location registration in the CSFB-incompatible mobile communication system 1 will be described with reference to FIG.
- the MSC / VLR 220 and MME 320 shown in FIG. 2 have the same configuration as the MSC / VLR 220A and MME 320A shown in FIG. 1 except for the function corresponding to the location registration information.
- a CSFB location registration request signal is transmitted from the CSFB-compatible mobile communication terminal 100 to the MME 320 of the 3.9G network 300 (S001 in FIG. 2).
- the MME 320 that has received the CSFB location registration request signal requests the subscriber accommodation station 400 to perform location registration in the 3.9G network (S002 in FIG. 2).
- the subscriber accommodation station 400 Upon receiving the location registration request, the subscriber accommodation station 400 performs location registration in the 3.9G network 300, and then transmits subscriber information such as contract information of the mobile communication terminal 100 that has requested location registration to the MME 320. (S002 in FIG. 2).
- subscriber information such as contract information of the mobile communication terminal 100 that has requested location registration to the MME 320.
- an E-UTRAN line identifier is generated as in the CSFB-compatible mobile communication system 1A.
- the MME 320 since the MME 320 that has received the CSFB location registration request signal does not have a location registration information support function unlike the CSFB-compatible mobile communication system 1A, the MME 320 responds to the signal related to the location registration request in the 2G / 3G network 200. Do not process. As a result, location registration in the 2G / 3G network 200 is not performed, and the MME 320 generates a location registration response signal including only the E-UTRAN line identifier corresponding to the location registration in step S002. Then, the MME 320 transmits the location registration response signal to the mobile communication terminal 100 (S007 in FIG. 2).
- the mobile communication terminal 100 Due to the location registration response signal including only the E-UTRAN line identifier, the mobile communication terminal 100 is set to be located only in the 3.9G network and cannot switch the mobile communication network as described above. In addition, it is impossible to receive a voice call service by CSFB.
- the CSFB-compatible mobile communication terminal 100 has a communication function capable of receiving broadcast information from both mobile communication networks 200 and 300, but is set to preferentially reside in the 3.9G network 300. ing. For this reason, in the mobile communication system 1 not compatible with CSFB, the mobile communication terminal 100 has been in the 3.9G network 300 before being in the 2G / 3G network 200, and in addition, in the 2G / 3G network 200. Since the outgoing call to the mobile communication terminal 100 is not made through the 3.9G network 300, the mobile communication terminal 100 cannot be located in the 2G / 3G network 200.
- the mobile communication terminal 100 has a function to be described later in order to eliminate such a state, and the mobile communication system 1 that does not support CSFB can also receive a voice call service.
- the mobile communication terminal 100 that can receive the voice call service even in the CSFB non-compliant mobile communication system 1 will be described in detail.
- the mobile communication terminal 100 can receive both the data communication service and the voice call service by the CSFB in the CSFB-compatible mobile communication system 1A.

This is realized by reading and writing data in the main storage devices 12 and 13.
- FIG. 4 is a schematic configuration diagram of the mobile communication terminal 100.

- the mobile communication network can be selectively located, and when data communication is performed, it is set to be preferentially located in the 3.9G network 300, and when performing a voice call, 2GB / 3G by CSFB.
- This is a mobile communication terminal compatible with CSFB in which the mobile communication network can be switched so as to be in the network 200.
- the mobile communication terminal 100 is connected to both mobile communication networks 200 and 300. Since each of the broadcast information can be received, the mobile communication terminal 100 can be located in the 2G / 3G network 200 without performing CSFB when receiving a voice call service by each function described later. Depending on the roaming area, there may be a mobile communication system in which only the 3.9G network 300 exists. In this case, of course, the voice call service cannot be received. The mobile communication terminal 100 determines that it is an area where it cannot receive such a voice call service because it cannot receive broadcast information from the 2G / 3G network 200.
- the CSFB non-compliant network permissible setting unit 110 does not know whether the location of the user of the mobile communication terminal 100 is a region corresponding to the CSFB compatible mobile communication system 1A or a region corresponding to the CSFB non-compatible mobile communication system 1. Whether to select a communication mode in which only data communication can be performed is set.
