Description

  The present invention relates to a location register for performing location registration of a mobile communication terminal, a location registration system, and a location registration method.

  In order to efficiently receive incoming calls to mobile communication terminals such as mobile phones, it is necessary to sequentially grasp where the mobile communication terminal that moves around is currently located. When a mobile communication terminal enters a different location registration area as it moves, the location information of the mobile communication terminal is moved from the mobile communication terminal A process called position registration is performed for transmitting to the register and registering the position information in the location register. Even if the mobile communication terminal stays within the same location registration area, the mobile communication terminal is not turned off, and the mobile communication terminal is not moving out of the communication range. In order to notify the location register, the location registration is performed periodically (for example, every 60 minutes).

  In the conventional location registration method, in the periodic location registration, the mobile communication terminal and the mobile communication terminal, such as transmission of location information from the mobile communication terminal to the location register, transmission of a location registration response signal from the location register to the mobile communication terminal, Information is transmitted to and received from the location register at regular intervals. Therefore, traffic is continuously generated on the data transmission path between the mobile communication terminal and the location register. In addition, due to the rapid spread of mobile phones in recent years, traffic on the data transmission path between the mobile communication terminal and the location register due to location registration is steadily increasing. Such an excessive increase in traffic may cause troubles such as communication failure.

  Here, it is also conceivable to reduce the data transmission path traffic between the mobile communication terminal and the location register due to the location registration by uniformly increasing the location registration cycle. However, if the location registration cycle is uniformly increased, the mobile communication terminal moves out of the communication range (or is turned off) even though the mobile communication terminal has moved out of the communication range (or turned off). The possibility (time zone) that the location register cannot grasp that increases. As a result, the frequency at which the location register performs invalid incoming call processing on such mobile communication terminals increases, and invalid incoming traffic increases.

  First, the configuration of the location registration system according to the present embodiment will be described. FIG. 1 is a configuration diagram of a location registration system according to the present embodiment. As shown in FIG. 1, the location registration system 10 according to the present embodiment includes a mobile communication terminal 12 configured by a mobile phone and the like, and a location register 14 that performs location registration of the mobile communication terminal 12. The The location register 14 includes a storage unit 16, a location registration cycle determination unit 18, and a location registration control unit. Hereinafter, each component will be described in detail.

  The storage unit 16 stores a position information management table 16a. FIG. 2 is a configuration diagram of the position information management table 16a. In the position information management table 16a, as shown in FIG. 2, the ID of each of the plurality of mobile communication terminals 12 managed by the location register 14, the position information of each of the plurality of mobile communication terminals 12, and the plurality of Each mobile communication terminal 12 includes the number of stagnations (information related to movement status). Here, as the location information of the mobile communication terminal 12, for example, the number of the location registration area in which the mobile communication terminal 12 currently exists corresponds to the location information, and is updated each time the location registration control unit 20 receives the location information. The number of stagnations is information indicating how long the mobile communication terminal 12 has stayed in the same location registration area. For example, the stagnation frequency is a predetermined number for the mobile communication terminal 12 to update the location information. This number corresponds to the number of periods of the period indicating the number of periods in the same location registration area.

  The location registration cycle determination unit 18 determines the location registration cycle of the mobile communication terminal 12 based on the number of stagnations of the mobile communication terminal 12 stored in the location information management table 16 a of the storage unit 16. More specifically, for example, the location registration control unit 20 performs the location registration of the mobile communication terminal 12 at a constant cycle (for example, 60 minutes), and the specific mobile communication terminal 12 has a predetermined number of times ( For example, when it is stagnant in the same location registration area for 10 times or more, the location registration cycle for the specific mobile communication terminal 12 is changed to a cycle longer than the predetermined cycle (for example, 120 minutes).

  The location registration control unit 20 transmits the location registration cycle determined by the location registration cycle determination unit 18 to the specific mobile communication terminal 12, and the specific mobile communication according to the transmitted location registration cycle. The position information of the mobile communication terminal 12 transmitted from the terminal 12 is received, and the position registration of the mobile communication terminal 12 is performed based on the received position information. That is, when performing location registration for each of the plurality of mobile communication terminals 12, the location registration control unit 20 performs location registration at different periods according to the number of stagnations for each of the plurality of mobile communication terminals 12.

  Next, the operation of the location registration system according to the present embodiment will be described, and the location registration method according to the embodiment of the present invention will be described. FIG. 3 is a diagram showing a procedure for performing location registration of the mobile communication terminal 12 in the location registration system 10 according to the present embodiment.

  In performing the location registration of the mobile communication terminal 12 in the location registration system 10 according to the present embodiment, first, a location registration request is transmitted from the mobile communication terminal 12 to the location register 14. The location registration request includes location information (location registration area) indicating the location where the mobile communication terminal 12 currently exists. The location registration request transmitted from the mobile communication terminal 12 is received by the location registration control unit 20 of the location register 14.

  When the location registration request is received by the location registration control unit 20, a location information read request for reading the location information of the mobile communication terminal 12 and the number of stagnations is output from the location registration control unit 20 to the storage unit 16. Is done.

  When such a position information read request is output to the storage unit 16, a position information read response is output from the storage unit 18 to the position registration control unit 20. Here, the position information read response includes the position information of the mobile communication terminal 12 read from the position information management table 16a (that is, the position information at the previous position registration) and the number of stagnation.

  Here, when the position information received from the mobile communication terminal 12 is the same as the position information included in the position information management table 16a, that is, when the mobile communication terminal 12 is registered at the previous position and at the current position registration. Are also present in the same location registration area, the location registration control unit 20 adds 1 to the number of stagnations of the mobile communication terminal 12. On the other hand, when the position information received from the mobile communication terminal 12 is different from the position information included in the position information management table 16a, that is, the mobile communication terminal 12 is different between the previous position registration and the current position registration. If it exists in the location registration area, the location registration control unit 20 resets the stagnation count of the mobile communication terminal 12 to zero.

  When the number of stagnations is calculated by the position registration control unit 20 (1 is added or reset to 0), the calculated number of stagnations is stored in the position information management table 16a of the storage unit 16, and The position information in the position information management table 16 a of the storage unit 16 is updated to the position information received from the mobile communication terminal 12. When the position information received from the mobile communication terminal 12 is the same as the position information included in the position information management table 16a, only the number of stagnations is stored in the position information management table 16a, and the position information is updated. It is not necessary.

  Further, when the number of stagnations of the mobile communication terminal 12 is calculated by the location registration control unit 20, a location registration cycle determination request is output from the location registration control unit 20 to the location registration cycle determination unit 18. Here, the location registration cycle determination request includes the number of stagnations of the mobile communication terminal 12 calculated by the location registration control unit 20.

  When a location registration cycle determination request is output from the location registration control unit 20, the location registration cycle determination unit 18 determines the location registration cycle of the mobile communication terminal 12. More specifically, when the number of stagnations of the mobile communication terminal 12 is less than a certain number of times (for example, 10 times), that is, when the mobile communication terminal 12 has not stayed in the same location registration area for a certain period of time, The location registration cycle of the mobile communication terminal 12 is determined as a normal location registration cycle (for example, 60 minutes). On the other hand, when the number of stagnations of the mobile communication terminal 12 becomes a certain number (for example, 10 times) or more, that is, when the mobile communication terminal 12 stays in the same location registration area for a certain time or more, the mobile communication terminal The location registration cycle of the terminal 12 is determined to be a constant cycle (for example, 120 minutes) longer than the normal location registration cycle.

  When the location registration cycle of the mobile communication terminal 12 is determined by the location registration cycle determination unit 18, the location registration cycle is output from the location registration cycle determination unit 18 to the location registration control unit 20 as a location registration cycle determination response. The The location registration cycle is transmitted from the location registration control unit 20 to the mobile communication terminal 12 as a location registration response.

  When the mobile communication terminal 12 receives a location registration response including the location registration cycle, the mobile communication terminal 12 starts a timer for the location registration cycle, and the location register 14 is sent from the mobile communication terminal 12 by the timeout of the timer. In response to this, a location registration request is transmitted, and thereafter, these processes are repeated.

  Next, operations and effects of the location registration system according to the present embodiment will be described. In the location registration system 10 according to the present embodiment, the location registration cycle determination unit 18 is based on the number of stagnations of the mobile communication terminal 12 that is a measure for the time that the mobile communication terminal 12 exists in the same location registration area. The location registration cycle of the mobile communication terminal 12 is determined, and the location registration control unit 20 performs location registration of the mobile communication terminal 12 according to the cycle. Therefore, it is possible to lengthen the period of location registration for the mobile communication terminal 12 that is mainly used in a limited area and has a low need for frequent location registration. As a result, traffic on the data transmission path between the mobile communication terminal 12 and the location register 14 can be reduced.

  Hereinafter, a first modification of the location registration system 10 according to the present embodiment will be described. In the location registration system 10 according to the above embodiment, the number of stagnations of the mobile communication terminal 12 is stored in the location information management table 16a of the storage unit 16, and the location registration cycle determination unit 18 performs mobile communication based on the number of stagnations. The location registration cycle of the terminal 12 is determined, and the location registration control unit 20 performs the location registration of the mobile communication terminal 12 based on the location registration cycle determined based on the number of stagnations as described above. As shown in FIG. 4, a location information management table 16b including the frequency of incoming calls to the mobile communication terminal 12 is stored in the storage unit 16, and the location registration cycle determination unit 18 is based on the frequency of incoming calls to the mobile communication terminal 12. The location registration cycle of the mobile communication terminal 12 is determined, and the location registration control unit 20 determines the location of the mobile communication terminal 12 based on the location registration cycle determined based on the incoming frequency as described above. It may perform the registration.

  FIG. 5 is a diagram showing a procedure for performing location registration of the mobile communication terminal 12 in the present modification. When a location registration request is transmitted from the mobile communication terminal 12 to the location registration control unit 20 of the location register 14 and a location information read request is output from the location registration control unit 20 to the storage unit 16, From the stored location information management table 16b, the location information of the mobile communication terminal 12 (that is, location information at the time of previous location registration) and the frequency of incoming calls to the mobile communication terminal 12 are read, and the location information read response is the location information. It is output to the registration control unit 20.

  Here, when the position information received from the mobile communication terminal 12 is different from the position information included in the position information management table 16b, that is, when the mobile communication terminal 12 is at the previous position registration and the current position registration. If the location information is in a different location registration area, the location information in the location information management table 16 b of the storage unit 16 is updated to the location information received from the mobile communication terminal 12. On the other hand, when the position information received from the mobile communication terminal 12 and the position information included in the position information management table 16b are the same, that is, when the mobile communication terminal 12 is at the previous position registration or at the current position registration. If they exist in the same location registration area, the location information in the location information management table 16b of the storage unit 16 is not updated.

  When the location information reading response is received by the location registration control unit 20, a location registration cycle determination request is output from the location registration control unit 20 to the location registration cycle determination unit 18. Here, the location registration cycle determination request includes the frequency of incoming calls to the mobile communication terminal 12 included in the location information read response.

  When a location registration cycle determination request is output from the location registration control unit 20, the location registration cycle determination unit 18 determines the location registration cycle of the mobile communication terminal 12. More specifically, when the incoming frequency of the mobile communication terminal 12 is a certain number of times (for example, 2 times / 1 hour) or more, the location registration cycle of the mobile communication terminal 12 is a normal location registration cycle (for example, 60 minutes). Is determined. On the other hand, when the incoming frequency of the mobile communication terminal 12 becomes less than a certain number of times (for example, 2 times / 1 hour), the location registration cycle of the mobile communication terminal 12 is a certain cycle longer than the normal location registration cycle. (For example, 120 minutes).

  When the location registration cycle of the mobile communication terminal 12 is determined by the location registration cycle determination unit 18, the location registration cycle is included in the location registration cycle determination response and output to the location registration control unit 20. And transmitted to the mobile communication terminal 12.

  When the mobile communication terminal 12 receives a location registration response including the location registration cycle, the mobile communication terminal 12 starts a timer for the location registration cycle, and the location register 14 is sent from the mobile communication terminal 12 by the timeout of the timer. In response to this, a location registration request is transmitted, and thereafter, these processes are repeated.

  As in this modification, the location registration cycle determining unit 18 determines the location registration cycle based on the information on the frequency of incoming calls to the mobile communication terminal 12, and the location registration control unit 20 determines the location of the mobile communication terminal 12 according to the cycle. By performing location registration, it is possible to lengthen the location registration cycle for the mobile communication terminal 12 that is mainly used for outgoing calls and that is not often required to perform location registration. As a result, traffic on the data transmission path between the mobile communication terminal 12 and the location register 14 can be reduced.

  In the location information management system 10 according to the embodiment and the above-described modification, the location registration cycle determination unit 18 is based on either the number of stagnations of the mobile communication terminal 12 or the frequency of incoming calls to the mobile communication terminal 12. The location registration cycle of the mobile communication terminal 12 is determined, and the location registration control unit 20 sets the location registration cycle determined based on either the number of stagnations of the mobile communication terminal 12 or the frequency of incoming calls to the mobile communication terminal 12. Based on both the number of stagnations of the mobile communication terminal 12 and the frequency of incoming calls to the mobile communication terminal 12, the location registration cycle determining unit 18 performs the movement of the mobile communication terminal 12 based on the location registration. The position registration cycle of the communication terminal 12 is determined, and the position registration control unit 20 is determined based on both the number of stagnations of the mobile communication terminal 12 and the frequency of incoming calls to the mobile communication terminal 12. And it may be carried out location registration of the mobile communication terminal 12 on the basis of the location registration period.

  The position of the mobile communication terminal 12 is determined based on both the number of stagnations of the mobile communication terminal 12 and the frequency of incoming calls to the mobile communication terminal 12, and the position of the mobile communication terminal 12 is registered based on the position registration period. A plurality of mobile communication terminals as compared with the case where the position registration cycle is determined based only on the number of stagnations of the communication terminal 12 or the case where the position registration cycle is determined based only on the frequency of incoming calls to the mobile communication terminal 12 For each of the twelve, location registration can be performed at a period extremely suitable from the viewpoints of both traffic reduction in location registration and reduction of invalid incoming traffic. As a result, it is possible to efficiently reduce the traffic on the data transmission path between the mobile communication terminal 12 and the location register 14.

  Then, the 2nd modification of the position registration system 10 concerning this embodiment is demonstrated. That is, this modification is based on the number of stagnations of the mobile communication terminal 12 stored in the location information management table 16a of the storage unit 16 in the location registration system 10 according to the embodiment. The location registration management time of the mobile communication terminal 12 is further determined, and the location registration control unit 20 registers the location of the mobile communication terminal 12 within the range of the management time determined by the location registration cycle determination unit 18. It is what I did.

  FIG. 6 is a diagram showing a procedure for performing location registration of the mobile communication terminal 12 in this modification. With respect to the point that the location registration cycle determining unit 18 determines the location registration cycle based on the number of stagnations of the mobile communication terminal 12, and the location registration control unit 20 performs location registration of the mobile communication terminal 12 according to the cycle. The operation is the same as that of the location registration system 10 according to the embodiment. In the present modification, the location registration cycle determining unit 18 determines the location registration cycle based on the number of stagnations of the mobile communication terminal 12, and the mobile communication terminal stored in the location information management table 16 a of the storage unit 16. Based on the number of stagnations 12, the location registration management time of the mobile communication terminal 12 is further determined. More specifically, when the number of stagnations of the mobile communication terminal 12 is less than a certain number of times (for example, 10 times), that is, when the mobile communication terminal 12 has not stayed in the same location registration area for a certain period of time, The location registration cycle of the mobile communication terminal 12 is determined as a normal location registration cycle (for example, 60 minutes), and the location registration management time of the mobile communication terminal 12 is longer than the location registration cycle (for example, 70 minutes). It is determined. On the other hand, when the number of stagnations of the mobile communication terminal 12 becomes a certain number (for example, 10 times) or more, that is, when the mobile communication terminal 12 stays in the same location registration area for a certain time or more, the mobile communication terminal The location registration cycle of the terminal 12 is determined to be a constant cycle (for example, 120 minutes) longer than the normal location registration cycle, and the location registration management time of the mobile communication terminal 12 is longer than the location registration cycle ( For example, 130 minutes).

  The management time determined by the location registration cycle determination unit 18 is included in the location registration cycle determination response and is output to the location registration control unit 20.

  Thereafter, the management time is output to the storage unit 16, and is stored in the storage unit 16 as a location information management table 16c as shown in FIG. 7 together with the time when the location registration was finally performed (final update time). The

  Here, if there is no location registration request from the mobile communication terminal 12 even if the above management time has passed since the last update time, it is determined that the mobile communication terminal 12 has moved out of range or turned off, and the location registration control unit The management of the location information by 20 is finished (hereinafter, the incoming operation for the mobile communication terminal 12 is not performed).

  As described above, by determining the location registration management time of the mobile communication terminal 12 based on the number of stagnations of the mobile communication terminal 12, the position registration cycle determined based on the number of stagnations of the mobile communication terminal 12 is determined. And an appropriate management time can be set.

  In this modification, the location registration cycle determination unit 18 further includes the location information of the storage unit 16 in association with a mode in which the location registration cycle of the mobile communication terminal 12 is determined based on the frequency of incoming calls to the mobile communication terminal 12. Based on the frequency of incoming calls to the mobile communication terminal 12 stored in the management table 16b, the location registration management time of the mobile communication terminal 12 is further determined, and the location registration control unit 20 is determined by the location registration cycle determination unit 18. The location of the mobile communication terminal 12 may be registered within the range of the management time.

  Such a modification also corresponds to a mode in which the period of location registration of the mobile communication terminal 12 is determined based on both the number of stagnations of the mobile communication terminal 12 and the frequency of incoming calls to the mobile communication terminal 12. The determination unit 18 manages the location registration of the mobile communication terminal 12 based on both the number of stagnations of the mobile communication terminal 12 and the frequency of incoming calls to the mobile communication terminal 12 stored in the location information management table of the storage unit 16. The time may be further determined, and the location registration control unit 20 may register the location of the mobile communication terminal 12 within the range of the management time determined by the location registration cycle determination unit 18.

  Next, a location registration system according to the second embodiment of the present invention will be described with reference to the drawings. First, the configuration of the location registration system according to the present embodiment will be described. FIG. 8 is a configuration diagram of the location registration system 30 according to the present embodiment. As shown in FIG. 8, the location registration system 30 according to the present embodiment includes a plurality of visitors that perform location registration of the mobile communication terminal 12 and the mobile communication terminal 12 located in the management area (management area) managed by the mobile communication terminal 12. A location register (hereinafter referred to as VLR 32) and a home location register (hereinafter referred to as HLR 34) for managing position information of the mobile communication terminal 12 that moves beyond the management area of each of the plurality of VLRs 32 are configured. Here, the plurality of VLRs 32 and the HLR 34 are connected via a network 36.

  Each of the plurality of VLRs 32 includes a storage unit 38, a location registration cycle determination unit 40, and a VLR location registration control unit 42. The HLR 34 includes a storage unit 44 and an HLR location registration control unit 46. Hereinafter, each component will be described in detail.

  The storage unit 38 of the VLR 32 stores a VLR position information management table 38a. FIG. 9 is a configuration diagram of the VLR position information management table 38a. In the VLR position information management table 38a, as shown in FIG. 9, the ID of each of the plurality of mobile communication terminals 12 managed by the VLR 32, the position information of each of the plurality of mobile communication terminals 12, and the plurality of movements The number of stagnation of each communication terminal 12 is included. For the mobile communication terminal 12 that is not located in the management area of the VLR 32, the position information is “vacant”, and the number of stagnation is also blank.

  The location registration cycle determination unit 40 of the VLR 32 determines the location registration cycle of the mobile communication terminal 12 based on the number of stagnations of the mobile communication terminal 12 stored in the location information management table 38 a of the storage unit 38. More specifically, for example, the location registration control unit 42 performs the location registration of the mobile communication terminal 12 at a constant cycle (for example, 60 minutes), and the specific mobile communication terminal 12 has a predetermined number of times ( For example, when it is stagnant in the same location registration area for 10 times or more, the location registration cycle for the specific mobile communication terminal 12 is changed to a cycle longer than the predetermined cycle (for example, 120 minutes).

  The VLR location registration control unit 42 of the VLR 32 transmits the location registration cycle determined by the location registration cycle determination unit 40 to the specific mobile communication terminal 12, and the specific location is determined according to the transmitted location registration cycle. The location information of the mobile communication terminal 12 transmitted from the mobile communication terminal 12 is received, and the location registration of the mobile communication terminal 12 is performed based on the received location information. That is, when performing location registration for each of the plurality of mobile communication terminals 12, the location registration control unit 42 performs location registration at different periods according to the number of stagnations for each of the plurality of mobile communication terminals 12.

  The storage unit 44 of the HLR 34 stores an HLR position information management table 44a. FIG. 10 is a configuration diagram of the HLR position information management table 44a. In the HLR location information management table 44a, as shown in FIG. 10, the ID of each of the plurality of mobile communication terminals 12 and which VLR 32 of the plurality of mobile communication terminals 12 is managed by each of the plurality of VLRs 32, That is, information on which VLR 32 of the plurality of mobile communication terminals 12 is in the management area of the plurality of VLRs 32 is included.

  The HLR location registration control unit 46 of the HLR 34 manages which VLR 32 performs location registration of the mobile communication terminal 12 when the mobile terminal 12 moves beyond the management area of each of the plurality of VLRs 32.

  Next, the operation of the location registration system according to the present embodiment will be described. FIG. 11 is a diagram showing a procedure for performing location registration of the mobile communication terminal 12 in the location registration system 30 according to the present embodiment.

  First, consider a case where the mobile communication terminal 12 enters a specific VLR 32 management zone from another VLR 32 management zone. Here, before the mobile communication terminal 12 enters the management area of the specific VLR 32, the position information of the mobile communication terminal 12 in the position information management table 38a of the storage unit 38 of the VLR 32 is “free”. The number of stagnation is also blank.

  In the above state, when a location registration request including location information of the mobile communication terminal 12 is transmitted from the mobile communication terminal 12 to the VLR location registration control unit 42 of the VLR 32, the VLR location registration control unit 42 stores the storage unit. 38, a position information read request for reading the position information of the mobile communication terminal 12 and the number of stagnations is output.

  In response to the position information read request, a position information read response is output from the storage unit 38 to the VLR position registration control unit 42. Here, the position information read response includes the position information of the mobile communication terminal 12 read from the position information management table 38a (that is, position information at the time of previous position registration = “empty”). At this time, the number of stagnations in the position information management table 38a is blank, so that the number of stagnations is not output.

  When “vacant” is obtained as the position information, the stagnation count of the mobile communication terminal 12 is set to 0 by the VLR position registration control unit 42.

  Thereafter, a VLR storage request for notifying that the mobile communication terminal 12 has entered the management area of the VLR 32 is transmitted from the VLR location registration control unit 42 to the HLR location registration control unit 46 of the HLR 34. When the VLR storage request is received by the HLR location registration control unit 46 of the HLR 34, the VLR storage request is output to the storage unit 44, and the presence of the HLR location information management table 44a of the storage unit 44 regarding the mobile communication terminal 12 is present. The area VLR column is updated.

  When the update of the in-visit VLR column of the HLR location information management table 44a is completed, a VLR storage response is output from the storage unit 44 to the HLR location registration control unit 46, and the VLR storage response is sent to the mobile communication terminal 12. It is transmitted to the location registration control unit 42 of the VLR 32 that is in the area.

  On the other hand, when the stagnation count of the mobile communication terminal 12 is set to 0 by the VLR location registration control unit 42 of the VLR 32, the stagnation count is stored in the location information management table 38 a of the storage unit 38. The position information in the position information management table 38a is updated to the position information received from the mobile communication terminal 12.

  When the number of stagnations of the mobile communication terminal 12 is set to 0 by the VLR location registration control unit 42 of the VLR 32, a location registration cycle determination request is sent from the VLR location registration control unit 42 to the location registration cycle determination unit 40. Is output. Here, the location registration cycle determination request includes the number of stagnations (= 0) of the mobile communication terminal 12 set by the location registration control unit 20.

  When a location registration cycle determination request is output from the VLR location registration control unit 42, the location registration cycle determination unit 40 determines the location registration cycle of the mobile communication terminal 12. More specifically, when the number of stagnations of the mobile communication terminal 12 is less than a certain number of times (for example, 10 times), that is, when the mobile communication terminal 12 has not stayed in the same location registration area for a certain period of time, The location registration cycle of the mobile communication terminal 12 is determined as a normal location registration cycle (for example, 60 minutes). On the other hand, when the number of stagnations of the mobile communication terminal 12 becomes a certain number (for example, 10 times) or more, that is, when the mobile communication terminal 12 stays in the same location registration area for a certain time or more, the mobile communication terminal The location registration cycle of the terminal 12 is determined to be a constant cycle (for example, 120 minutes) longer than the normal location registration cycle. In this case, since the number of stagnations of the mobile communication terminal 12 is 0, the location registration cycle of the mobile communication terminal 12 is determined as a normal location registration cycle (for example, 60 minutes).

  When the location registration cycle of the mobile communication terminal 12 is determined by the location registration cycle determination unit 40, the location registration cycle is output from the location registration cycle determination unit 40 to the VLR location registration control unit 42 as a location registration cycle determination response. Is done. The location registration cycle is transmitted from the VLR location registration control unit 42 to the mobile communication terminal 12 as a location registration response. Hereinafter, when the mobile communication terminal 12 exists in the management area of the VLR 32, the location registration procedure of the mobile communication terminal 12 by the VLR 32 is the mobile communication by the location register 14 of the location registration system 10 according to the first embodiment. This is the same as the procedure for registering the location of the terminal 12.

  On the other hand, when the mobile communication terminal 12 moves to the management area of another VLR 32 and a VLR storage request is transmitted from the VLR location registration control unit 42 of the other VLR 32 to the HLR location registration control unit 46 of the HLR 34, the HLR 34 A location registration release request indicating that location registration should be terminated is transmitted from the HLR location registration control unit 46 to the VLR location registration control unit 42 of the VLR 32 in which the mobile communication terminal 12 has existed in the management area. When the location registration cancellation request is received by the VLR location registration control unit 42, the location registration cancellation request is output to the storage unit 38, and the corresponding mobile communication terminal 12 in the VLR location information management table 38 a of the storage unit 38. Is updated to “free”.

  Also in the location registration system 30 according to the present embodiment, a modification similar to that considered in the location registration system 10 according to the first embodiment can be considered. That is, in the location registration system 30 according to the above embodiment, the location registration cycle of the mobile communication terminal 12 is determined based on the number of stagnations of the mobile communication terminal 12, and the location registration control unit 20 is based on the number of stagnations as described above. The location registration of the mobile communication terminal 12 is performed based on the location registration period determined in this manner. As shown in FIG. 12, the location information management table 38b including the frequency of incoming calls to the mobile communication terminal 12 is stored in the VLR 32. The location registration cycle determination unit 40 determines the location registration cycle of the mobile communication terminal 12 based on the frequency of incoming calls to the mobile communication terminal 12, and the VLR location registration control unit 42 As described above, the location registration of the mobile communication terminal 12 may be performed based on the location registration period determined based on the incoming frequency. In this case, unlike the number of stagnations, the incoming call frequency cannot be calculated in each of the plurality of VLRs 32. Therefore, in this case, it is necessary to store the HLR location information management table 44b including the incoming call frequency not depending on the in-service VLR as shown in FIG. 13 in the storage unit 44 of the HLR 34.

  FIG. 14 is a diagram showing a procedure for performing location registration of the mobile communication terminal 12 in this modification. First, in a state where the mobile communication terminal 12 has entered the management area of a specific VLR 32 from the management area of another VLR 32, the mobile communication terminal 12 sends the VLR location registration control unit 42 of the VLR 32 to the mobile communication terminal 12. When a location registration request including location information is transmitted, a location information read request for reading location information of the mobile communication terminal 12 is output from the VLR location registration control unit 42 to the storage unit 38.

  In response to the position information read request, a position information read response is output from the storage unit 38 to the VLR position registration control unit 42. Here, the position information read response includes the position information of the mobile communication terminal 12 read from the position information management table 38b (that is, position information at the time of previous position registration = “free”). At this time, the incoming frequency of the location information management table 38b is blank.

  When “vacant” is obtained as the location information, the VLR location registration control unit 42 notifies the HLR location registration control unit 46 of the HLR 34 that the mobile communication terminal 12 has entered the management area of the VLR 32. Is sent. When the VLR storage request is received by the HLR location registration control unit 46 of the HLR 34, the VLR storage request is output to the storage unit 44, and the presence of the HLR location information management table 44a of the storage unit 44 regarding the mobile communication terminal 12 is present. The area VLR column is updated, and the incoming frequency of the mobile communication terminal 12 is read from the HLR location information management table 44a.

  When the update of the in-service VLR column of the HLR location information management table 44a is completed, the VLR including the incoming frequency of the mobile communication terminal 12 read out as described above from the storage unit 44 to the HLR location registration control unit 46. A storage response is output, and the VLR storage response is transmitted to the location registration control unit 42 of the VLR 32 in which the mobile communication terminal 12 is located.

  On the other hand, when the VLR storage response including the incoming frequency of the mobile communication terminal 12 is received by the VLR location registration control unit 42 of the VLR 32, the incoming frequency is stored in the location information management table 38b of the storage unit 38. The position information in the position information management table 38b of 38 is updated to the position information received from the mobile communication terminal 12.

  When a VLR storage response including the incoming frequency of the mobile communication terminal 12 is received by the VLR location registration control unit 42 of the VLR 32, the location registration cycle determination is performed from the VLR location registration control unit 42 to the location registration cycle determination unit 40. A request is output. Here, the location registration cycle determination request includes the incoming frequency of the mobile communication terminal 12 received by the location registration control unit 42.

  When a location registration cycle determination request is output from the VLR location registration control unit 42, the location registration cycle determination unit 40 determines the location registration cycle of the mobile communication terminal 12. More specifically, when the incoming frequency of the mobile communication terminal 12 is a certain number of times (for example, 2 times / 1 hour) or more, the location registration cycle of the mobile communication terminal 12 is a normal location registration cycle (for example, 60 minutes). Is determined. On the other hand, when the incoming frequency of the mobile communication terminal 12 becomes less than a certain number of times (for example, 2 times / 1 hour), the location registration cycle of the mobile communication terminal 12 is a certain cycle longer than the normal location registration cycle. (For example, 120 minutes).

  When the location registration cycle of the mobile communication terminal 12 is determined by the location registration cycle determination unit 40, the location registration cycle is output from the location registration cycle determination unit 18 to the VLR location registration control unit 42 as a location registration cycle determination response. Is done. The location registration cycle is transmitted from the VLR location registration control unit 42 to the mobile communication terminal 12 as a location registration response. Hereinafter, when the mobile communication terminal 12 exists in the management area of the VLR 32, the location registration procedure of the mobile communication terminal 12 by the VLR 32 is the same as in the first modification of the location registration system 10 according to the first embodiment. This is the same as the procedure for registering the location of the mobile communication terminal 12 by the location register 14.

  The operation when the mobile communication terminal 12 moves to the management area of another VLR 32 is the same as the operation in the location registration system 30 according to the second embodiment.

  Further, in the location information management system 30 according to the above-described embodiment and the above-described modification, the location registration cycle determination unit 40 of the VLR 32 determines either the number of stagnations of the mobile communication terminal 12 or the frequency of incoming calls to the mobile communication terminal 12. The position registration cycle of the mobile communication terminal 12 is determined based on the position, and the VLR position registration control unit 42 is determined based on either the number of stagnations of the mobile communication terminal 12 or the frequency of incoming calls to the mobile communication terminal 12. The location registration of the mobile communication terminal 12 is performed based on the registration cycle. This is because the location registration cycle determination unit 40 is based on both the number of stagnations of the mobile communication terminal 12 and the frequency of incoming calls to the mobile communication terminal 12. The VLR location registration control unit 42 determines the number of stagnations of the mobile communication terminal 12 and the frequency of incoming calls to the mobile communication terminal 12. Both may be carried out location registration of the mobile communication terminal 12 on the basis of the location registration period determined based on the.

  Further, the position registration system 30 according to the present embodiment can also perform a modification corresponding to the second modification of the position registration system 10 according to the first embodiment. In this case, the VLR location information management table 38c as shown in FIG. 15 is stored in the storage unit 38 of the VLR 32, and the location registration of the mobile communication terminal 12 is performed according to the procedure shown in FIG. The specific procedure of location registration in this case is the same as the procedure of location registration in the location registration system 30 according to the second embodiment, and the procedure for determining the management time and managing the location registration based on the management time is as follows. These are the same as the procedure for determining the management time and managing the location registration based on the management time in the second modification of the location registration system 10 according to the first embodiment.

  In this modification, the position registration cycle determination unit 40 further includes position information stored in the storage unit 38 in association with a mode in which the cycle of position registration of the mobile communication terminal 12 is determined based on the frequency of incoming calls to the mobile communication terminal 12. Based on the incoming frequency to the mobile communication terminal 12 stored in the management table 38b, the location registration management time of the mobile communication terminal 12 is further determined, and the VLR location registration control unit 42 The location registration of the mobile communication terminal 12 may be performed within the determined management time range.

  Such a modification also corresponds to a mode in which the period of location registration of the mobile communication terminal 12 is determined based on both the number of stagnations of the mobile communication terminal 12 and the frequency of incoming calls to the mobile communication terminal 12. The determination unit 40 manages the location registration of the mobile communication terminal 12 based on both the number of stagnations of the mobile communication terminal 12 and the incoming frequency of the mobile communication terminal 12 stored in the location information management table of the storage unit 38. The time may be further determined, and the VLR location registration control unit 42 may perform the location registration of the mobile communication terminal 12 within the range of the management time determined by the location registration cycle determination unit 40.

  In the first and second embodiments and their modifications, the mobile communication terminal 12 is based on the number of times the mobile communication terminal 12 has stagnated, the frequency of incoming calls to the mobile communication terminal 12, or the mobile communication terminal 12. The location registration period of the mobile communication terminal 12 is set to one of two periods based on both the number of stagnations and the frequency of incoming calls to the mobile communication terminal 12. Alternatively, it may be set to any one of more cycles. Further, the location registration cycle of the mobile communication terminal 12 may be continuously changed. This makes it possible to set a finer position registration cycle.

  Similarly, in the first and second embodiments and the modifications thereof, based on the number of stagnation of the mobile communication terminal 12, the frequency of incoming calls to the mobile communication terminal 12, or the mobile communication terminal Based on both the number of stagnation of 12 and the frequency of incoming calls to the mobile communication terminal 12, the management time of the location registration of the mobile communication terminal 12 was set to one of two times. You may make it set to either four or more time. Further, the location registration management time of the mobile communication terminal 12 may be continuously changed. This makes it possible to set a finer management time.

  In the first and second embodiments, the number of stagnations of the mobile terminal 12 is used as information related to the movement status of the mobile communication terminal, and the location registration of the mobile communication terminal 12 is performed based on the number of stagnations of the mobile communication terminal 12. However, this may set the position registration period of the mobile communication terminal 12 based on other information related to the movement status of the mobile communication terminal.

  For example, as information on the movement status of the mobile communication terminal, the position registration cycle of the mobile communication terminal 12 is set based on the action pattern of the mobile communication terminal 12 (or the action pattern of the person who owns the mobile communication terminal 12). You may make it set. Here, the behavior pattern may be a time zone, the number of stagnations in the time zone, a moving direction, and the like. More specifically, for example, an action pattern table 50 showing a relationship between a time zone as shown in FIG. 17 and an action pattern in the time zone is prepared in advance, and the mobile communication terminal 12 exists for each time zone. In the location registration area where the possibility is high, the location registration cycle is lengthened, and in the location registration area where the possibility that the mobile communication terminal 12 exists is low, the location registration cycle is shortened. If it demonstrates in the example shown in FIG. 17, when the mobile communication terminal 12 exists in the position registration area of the vicinity of a house, the period of a position registration will be lengthened in the time zone of 0: 0 to 7:30, and other than that If it exists in the location registration area, the location registration cycle is shortened. The behavior pattern table 50 may be generated based on past movements of the mobile communication terminal 12 and may be sequentially updated based on past movements of the mobile communication terminal 12. Further, the behavior pattern table 50 may be configured by distinguishing between the behavior pattern of Saturday and Sunday and the behavior pattern of weekdays.

  In the first and second embodiments, the number of stagnations of the mobile terminal 12 is used as information related to the movement status of the mobile communication terminal, and the location registration of the mobile communication terminal 12 is performed based on the number of stagnations of the mobile communication terminal 12. However, this may set the management time for the location registration of the mobile communication terminal 12 based on other information related to the movement status of the mobile communication terminal, such as the behavior pattern described above.
