Abstract

PROBLEM TO BE SOLVED: To provide a smooth call origination/termination service by facilitating cut-back to a database before shift even when there is a trouble in accessing to a new database after shift of the database.SOLUTION: When access to subscriber information subjected to shift is requested while shifting (copying) the subscriber information from a subscriber information management system 140b to a subscriber information management device 150, the access request is distributed while referring to a shift information management table in which a subscriber identifier corresponding to the subscriber information subjected to shift, a state of data shift to the subscriber information management device 150, and access destination information (a distribution destination of the access request) for the subscriber information are made correspondent. In accordance with the state of shift of the subscriber information to the subscriber information management device 150, the data shift state and the access destination information are rewritten in the shift information management table. During shift processing, the subscriber information in both the subscriber information management system 140b and the subscriber information management device 150 are rewritten.

Description

  The present invention relates to an access control management apparatus, an access control management method, and an access control management system, and in particular, an access control management apparatus and an access that can provide a smooth service even when a failure occurs in access to a migration destination database. The present invention relates to a control management method and an access control management system.

  In recent years, there has been a remarkable increase in smartphones, machine communication using vending machines, communication terminals incorporated in automobiles, etc., and increase in subscribers of LTE (Long Term Evolution) services. Along with this, traffic such as subscriber information such as contract information and location information managed by the network and processing signals for outgoing and incoming calls is increasing. For this reason, the capacity of a database for managing subscriber information and the processing capacity of a CPU (Central Processing Unit) of a call processing unit that processes call processing signals for making and receiving calls tend to be tight. To cope with such a problem, conventionally, a service management apparatus including a database unit and a call processing unit has been added. However, in consideration of further increase in subscribers and diversification of services in the future, simply adding the above-mentioned service management device increases the facilities.

  In addition, when using a service management device including a database unit and a call processing unit, an additional service management device is required if there is a factor in either the database capacity limitation or the CPU processing capability limitation. For this reason, for example, even when there is a margin in CPU processing capacity, it is necessary to add a service management device including a call processing unit, which causes problems such as generation of useless equipment costs and useless increase in equipment. It was.

  Conventionally, a visited exchange has accessed a call processing unit corresponding to a database unit in which subscriber information to be referenced and updated is stored. For this reason, each time the subscriber information is transferred, information about the subscriber information accommodation destination held by the serving exchange (information about which subscriber information of which subscriber is held in the database of which service control device) It was necessary to perform update work.

Therefore, as described in Non-Patent Document 1 below, a configuration in which a database unit and a call processing unit that are associated one-to-one in the above-described service monitoring apparatus are studied. Non-Patent Document 1 describes that a database unit and a call processing unit can be freely added and removed, respectively. Therefore, it is possible to suppress an increase in useless facilities.
Non-Patent Document 1 describes that the call processing unit determines and accesses which database unit holds the subscriber information to be referenced and updated. Therefore, the visited exchange can access any call processing unit, so that it is not necessary to update the information on the visited exchange side when the subscriber information is transferred, and a rapid service introduction can be expected.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
(Mobile communication terminal network system)
FIG. 1 is a schematic diagram showing a configuration of a mobile communication terminal network system 100 to which the present invention is applied.
The mobile communication terminal network system 100 includes a mobile communication terminal 110 (mobile communication terminal A111, mobile communication terminal B112, mobile communication terminal C113), a radio base station (BTS: Base Transceiver Station) 120 (120a, 120b, 120c), The exchange 130 (130a, 130b, 130c), the subscriber information management system 140 (140a, 140b), the subscriber information management apparatus 150, and the operation apparatus 160 are comprised. The subscriber information management system 140 (140a, 140b) includes a DB 141 (141a, 141b), which is a subscriber information database (hereinafter referred to as DB as appropriate), and an access control management device 142 (142a, 142b). . The access control management device 142 has a call processing unit 143 (143a, 143b), a writing / reading unit 144 (144a, 144b), and a migration information management table 145 (145a, 145b) that correspond one-to-one with the DB 141. Prepare each.

(General operation in mobile communication terminal network system)
In the mobile communication terminal network system 100 of the present embodiment, when a call is made between the mobile communication terminal A111 and the mobile communication terminal B112 by calling from the mobile communication terminal A111, the location information of the mobile communication terminal B112 (hereinafter, Acquisition of position information) is required. In response to the connection request from the mobile communication terminal A111 received via the radio base station 120a, the exchange 130a accesses either the subscriber information management system 140 or the subscriber information management apparatus 150, and the mobile communication terminal B112 The location information is acquired, and a connection request to the mobile communication terminal B112 is transmitted to the exchange 130b corresponding to the acquired location information. Each exchange 130 has information on which subscriber information management system 140 or subscriber information management device 150 holds subscriber information of each subscriber.

  Further, in the mobile communication terminal network system 100, when the mobile communication terminal C113 moves to an area covered by the radio base station 120c, the radio base station 120c accesses the subscriber information management system 140 or the subscriber information management device 150. The position information of the mobile communication terminal C113 is registered.

(Transfer of subscriber information in this embodiment)
In the present embodiment, the migration process of copying part or all of the subscriber information corresponding to the plurality of mobile communication terminals held by the subscriber information management system 140b to the newly added subscriber information management device 150 is performed. Assumed. The subscriber information is information including a user ID (subscriber identifier), a telephone number, location information, a service contracted by each mobile communication terminal, and the like of the mobile communication terminal used by the subscriber.

Here, the subscriber information migration process (copy) is to make a copy of the subscriber information in another DB while keeping the subscriber information held in a certain DB in this DB.
The subscriber information migration process (copy) may be performed in units of subscriber information corresponding to one telephone number, and each corresponds to a plurality of telephone numbers (phone number bands) whose upper digits are a common number. It may be performed for a plurality of subscriber information units. When the subscriber information migration process is performed for each telephone number band, an instruction for the migration process is given to a plurality of subscriber information to be migrated, and the subscriber information instructed is sequentially copied one by one.

  Further, in the present embodiment, confirmation (access test) is performed as to whether or not access to a part of the subscriber information transferred to the subscriber information management device 150 is normal. It is assumed that the migration process is completed accordingly. Then, after it is confirmed that the access to the copied subscriber information is normal, the access destination for the subscriber information is transferred from the transfer source subscriber information management system 140b (DB 141b) to the transfer destination subscriber information. The management device 150 (DB 151) is switched to. Further, when it is not confirmed that the access to the subscriber information transferred to the DB 151 is normal, the access destination for accessing the subscriber information is set as the transfer source subscriber information management system 140b. Then, the subscriber information is written again in the migration destination DB 151. Note that the access destination may be switched at any timing after the normality of the access is confirmed, and it is not necessary to switch the access destination immediately after the access test. As a result, an access error occurs after switching from the subscriber information management system 140b to the added subscriber information management apparatus 150, and it is necessary to switch back from the migration destination subscriber information management apparatus 150 to the migration source subscriber information management system 140b. Disappears.

Hereinafter, each device will be described.
(Access control management device)
The access control management device 142 includes a call processing unit 143, a read / write unit 144, and a migration information management table 145. Hereinafter, each part will be described.
(Migration information management table)
The migration information management table 145 is a table in which at least a user ID (subscriber identifier) of each mobile communication terminal and access destination information are associated with each other. After the start of the transfer process, the transfer state of the subscriber information is further associated.

2A to 2C are migration information management tables 145c, 145d, and 145e showing specific examples of the migration information management table 145b.
FIG. 2A shows a migration information management table 145c before the subscriber information migration process is started. The DB 141b manages the transition state of subscriber information (telephone number band: 090-2000-xxx). FIG. 2B is a migration information management table 145d created at the start of migration processing. The migration information management table 145d is a table created by adding an item about the migration state of subscriber information to the migration information management table 145c. In the migration information management table 145d, the user ID (subscriber identifier) of each mobile communication terminal, the access destination information, and the migration state of the subscriber information are associated with each other. In FIG. 2 (b), the case where the transition status of each subscriber information to the DB 151 is “not migrated” is described as “not yet”. In the migration information management table 145e shown in FIG. 2C, part of the subscriber information has been migrated, and the migration status and part of the access destination information in the migration information management table 145d shown in FIG. It is a table.

“Access destination information” in the migration information management table 145 is information indicating either the migration source DB 141 b or the migration destination DB 151 of the subscriber information. If subscriber information is held in both the DB 141b and the DB 151 during the subscriber information migration process, the DB designated in the “access destination information” is preferentially accessed.
The migration information management table 145 is referred to by the call processing unit 143 when the call processing unit 143 receives an access request to the subscriber information to be migrated during the migration process of the subscriber information from the DB 141b to the DB 151. .

(Call processor)
The call processing unit 143 controls a call processing signal with an opposite device such as the exchange 130, and distributes an access request from the exchange 130 to either the DB 141 or the DB 151 in which the access target subscriber information is held. Have The call processing unit 143 has a function of referring to, rewriting, and reading out subscriber information held in the DB 141 or DB 151.

  The access request includes all requests that require access to the subscriber information. Examples of the access request include a subscriber information reference request, a location information registration request, and a rewrite request from the mobile communication terminal 110. In addition, a request for an access test for confirming the normality of access to subscriber information migrated from the DB 141b held by the DB 151 is included. The registration request is an aspect of a rewrite request.

  The call processing unit 143 functions as part of the subscriber information management system 140 in association with the DB 141. Then, after the migration of subscriber information from the DB 141 to another DB 151 is completed, it is disconnected from the DB 141. After being disconnected from the DB 141, the call processing unit 143 has a function of distributing access requests to a plurality of DBs without being associated with a specific DB.

  When the migration process for migrating subscriber information from the DB 141b to another DB 151 is in progress, the access request from the exchange 130 refers to the “access destination information” in the migration information management table 145 (145d, 145e) by the call processing unit 143b. Are distributed. The call processing unit 143 refers to the migration information management table 145 when distributing access requests from the exchange 130.

(Read / write unit)
The read / write unit 144 writes and rewrites the migration information management table 145. The reading / writing unit 144 rewrites the migration information management table 145 when each subscriber information has been migrated between DBs or when the access destination information is changed.
Further, the read / write unit 144 has a function of reading subscriber information from the migration source DB 141b during the migration process and writing the subscriber information to the migration destination DB 151. Even when registration of location information or the like is performed in both the DB 141b and the DB 151 during the migration process, it has a function of reading information from one DB and writing information to the other DB.
Read / write unit 144 is connected to operation device 160 and receives an instruction from operation device 160.

(Configuration of subscriber information database)
The subscriber information databases DB141 and DB151 hold subscriber information corresponding to a plurality of mobile communication terminals. In the subscriber information management system 140 that is the transfer source of subscriber information, the DB 141 is provided in association with a specific call processing unit 143. The subscriber information management apparatus 150, which is the destination of subscriber information, includes the DB 150, but the call processing unit is separated.
DBs 141 and 151 hold position information of a plurality of mobile communication terminals. In addition, the DBs 141 and 151 also hold the subscriber information on the location information rank corresponding to each mobile communication terminal.

  The location information of the mobile terminal device that is one component of the subscriber information is registered (rewritten) in the DBs 141 and 151 as needed. The location information is generally information indicating one of the exchanges 130 connected to the radio base station 120 to which the mobile communication terminal 110 is connected. The subscriber information may be distributed and held in the DB 141 of the plurality of subscriber information management systems 140 and the DB 151 of the subscriber information management apparatus 150. In this case, the subscriber information management system 140 and the subscriber information management device 150 hold the subscriber information to be managed for each telephone number band.

The DBs 141 and 151 are rewritten by referring to the subscriber information by the call processing unit 143 in response to a request from the mobile communication terminal 110. In addition, during the migration of subscriber information, when writing is required in both the migration source and migration destination DBs, the subscriber information is read from one DB by the read / write unit 144, and the other DB is The stored subscriber information is rewritten.
In addition to requests from the call processing unit 143, the DBs 141 and 151 inquire and register subscriber information in the DBs 141 and 151 and update contract information in response to data access from a customer management device (not shown). . For example, the customer management device requests registration of subscriber information corresponding to a mobile communication terminal for which a new usage contract has been made, contract information for which a new service contract has been made, and the like.

FIGS. 3A and 3B are examples of subscriber information held by each of the DBs 141a and 141b before the subscriber information migration process (before the DB 151 is installed). For example, the DB 141a of the subscriber information management system 140a holds subscriber information having a telephone number “090-1000-xxx”, and the DB 141b of the subscriber information management system 140b stores “090-2000- ×”. Subscriber information having a telephone number “XXX” is held. Here, xxxx represents an arbitrary 4-digit number. Each subscriber information is held in association with a telephone number, an identification number, a contracted contract service, and location information. For example, IMSI (International Mobile Subscriber Identity) or IMEI (International Mobile Equipment Identity) is used as the identification number.
The access control management device 142 is monitored by the operation device 160 and an instruction is transmitted. The DBs 141 and 151 are stored in a memory such as a RAM (Random Access Memory). As a result, real-time and high-speed access from the call processing unit 143 to the DB 141 is possible.

(Mobile communication terminal)
In the mobile communication terminal network system 100, the mobile communication terminal A111, the mobile communication terminal B112, and the mobile communication terminal C113 are examples of the mobile communication terminal 110, and specifically a general mobile phone or the like.
(Radio base station)
The radio base station 120 has a function of securing a communication line with a mobile communication terminal located in an area (cell) covered by itself by transmitting or receiving radio waves.

(switch)
The exchange 130 transmits a registration information registration request for the mobile communication terminal 110 located in an area covered by the radio base station 120 connected to the exchange 130 to the subscriber information management system 140 or the subscriber information management apparatus 150. In addition, the exchange 130 receives a connection request from the mobile communication terminal 110 and transmits a request for acquiring position information of an area where the communication terminal of the called party is located to the call processing unit 143. In addition, a connection request is transmitted to the corresponding exchange 130 based on the location information of the communication terminal of the called party received from the call processing unit 143.

  When each exchange 130 makes an access request to the subscriber information held in the subscriber information management system 140a, the access request is transmitted in consideration of the accommodation destination of the subscriber information to be accessed. This is because the call processing unit 143a has a one-to-one correspondence with the DB 141a that holds subscriber information, and it is necessary to distribute access requests on the exchange 130 side. Similarly, when requesting access to the subscriber information held in the subscriber information management system 140 in the state where the subscriber information is being migrated, the access is made in consideration of the location of the subscriber information to be accessed. Send a request.

  On the other hand, when each exchange 130 transmits an access request to the subscriber information held in the migration destination DB 151, it is not necessary to transmit the access request in consideration of the accommodation destination of the subscriber information to be accessed. . The call processing unit 143b and the subscriber information migration destination DB 151 are not associated one-to-one. For this reason, the call processing unit 143b appropriately distributes access requests based on the subscriber information accommodation destination information held by itself.

  The switch 130 includes a mobile management device (MME), a mobile switching center (MSC / VLR), a subscriber packet switch (SGSN). ) And the like. Here, MME is a node which comprises a LTE accommodation core network (EPC). The MSC / VLR is a node constituting the 3G core network, and is a circuit switched (CS) call switch. SGSN is a packet switching (PS) call switch.

(Operation device)
The operation device 160 has a function of monitoring the call processing unit 143, the reading / writing unit 144, the subscriber information management system 140, and the subscriber information management device 150, and transmitting instructions. The operation device 160 has a function of instructing the reading / writing unit 144 to read and write the subscriber information at the start of the subscriber information migration process. Further, when the operation device 160 performs an access test for confirming the normality of access to the subscriber information subjected to the migration process, the operation device 160 instructs the read / write unit 144 to access the destination information in the migration information management table 145. Is transmitted to the migration destination DB 151. When the normality cannot be confirmed in the access test, an instruction to rewrite the access destination information of the migration information management table 145 to the migration source DB 141b is transmitted. These instructions are transmitted according to instructions input by a maintenance person who operates the operation device 160.

(Access control method in this system)
Hereinafter, an access control method from the call processing unit 143 to the migration target subscriber information when the subscriber information is copied from the DB 141b of the subscriber information management system 140b to the DB 151 of the subscriber information management apparatus 150 will be described.
In connection with the “migration process”, the subscriber information is classified into three states: “before the migration process is started”, “migrating process is in progress”, and “migration process is completed”. In describing the operation of the present system, the states of “before start of migration processing”, “during migration processing”, and “completion of migration processing” in the present embodiment will be described first.

  “Before the start of the migration process” is a state in which the subscriber information has not received an instruction for the migration process from the operation device 160. “Migration processing complete” means that the subscriber information has been copied to the migration destination DB 151 upon receipt of the migration processing instruction from the operation device 160, and that the access to the subscriber information copied to the DB 151 is normal. This means that the migration process has been completed. The migration process may be completed immediately after the access normality for a part of the subscriber information subjected to the migration process is confirmed, but the timing of completion of the migration process may be any time after the access normality confirmation. In addition, when a plurality of subscriber information is collectively instructed to perform migration processing and an access test is performed on all subscriber information that has undergone migration processing, the access normality of all subscriber information is confirmed. It is also possible to complete the transition after waiting.

“Transition processing in progress” refers to a state in which subscriber information of a certain number band has received a transition processing instruction from the operation device 160 but has not been “completion of migration processing”. That is, the subscriber information “being transferred” includes, for example, subscriber information in the following state.
(I) Subscriber information that has received an instruction for migration processing from the operation device 160 but has not yet been copied to the DB 151. (ii) Received an instruction for migration processing from the operation device 160, and has been copied to the DB 151. But subscriber information that has not been tested for access

(Iii) Upon receiving the migration processing instruction from the operation device 160, copying to the DB 151 has been completed and an access test has been performed, but there is a problem in accessing the subscriber information held in the DB 151, and the subscriber information In response to the migration processing instruction from the subscriber information (iV) operation device 160 whose “access destination information” is written back to the DB 141b, the copy to the DB 151 is completed, the access test is performed, and the access test result is good. However, the subscriber information in which the “access destination information” of the subscriber information is written back to the DB 141b in order not to make “migration processing complete” immediately.

  When there is an access request from the exchange 130 “before the start of the migration process”, the call processing unit 143b accesses the associated DB 141b without referring to the migration information management table 145. When there is an access request from the exchange 130 during the “migration process”, the call processing unit 143b accesses either the DB 141b or the DB 151 defined in the “access destination information” of the migration information management table 145. To do. If there is an access request from the exchange 130 after the “migration processing is completed”, the call processing unit 143b accesses the migration destination DB 151.

(Operation of this system)
The operation in the access control management system in this embodiment will be described below. In the following description, an operation in the case of instructing a migration process to the DB 151 for subscriber information corresponding to a plurality of telephone numbers (phone number bands) held in the DB 141b will be described. In addition, when the access normality to a part of the plurality of subscriber information subjected to the migration process can be confirmed, all the access destinations of the plurality of subscriber information subjected to the migration process are set as the migration destination DB 151. The operation of will be described.

(Addition of migration status item to migration information management table)
The operation device 160 adds an item of the migration state of the subscriber information to the migration destination DB 151 in the migration information management table 145 with the start of the subscriber information migration process. The migration information management table 145 includes at least a user ID of the mobile communication terminal corresponding to the subscriber information to be migrated, access destination information for accessing the subscriber information to be migrated, and migration of subscriber information. The state of transition to the previous DB 151 is associated and held.
As shown in FIG. 2B, in the migration information management table 145 (145d) at the start of migration processing, the “access destination information” of all the subscriber information to be migrated is the migration source DB 141b. .

(Subscriber information migration process)
Hereinafter, a migration process in which subscriber information held in the DB 141b of the subscriber information management system 140b is copied to the DB 151 of the subscriber information management apparatus 150 will be described.
The subscriber information is copied from the DB 141b to the DB 151 in response to an instruction from the operation device 160. The subscriber information is copied one by one in order by the reading / writing unit 144 repeatedly reading out the subscriber information from the DB 141b one by one and writing it into the DB 151.
If there is an abnormality in access, it is copied again from the DB 141b to the DB 151 in response to an instruction from the operation device 160.

(Rewrite migration information management table)
The “access destination information” and “migration state” of the subscriber information in the migration information management table 145 are rewritten by the read / write unit 144. The “transition state” of the subscriber information is rewritten to “transferred” by the reading / writing unit 144 every time one copy of the subscriber information is completed. The “access destination information” of the subscriber information is rewritten to “DB 151” of the migration destination in response to an instruction from the operation device 160 at the start of the access test. Further, the “access destination information” of the subscriber information is written back to the “DB 141b” of the migration source in response to an instruction from the operation device 160 when the access to the subscriber information copied to the DB 151 is not normal.

FIG. 2C shows the rewritten migration information management table 145 (145e). Since the subscriber information corresponding to the telephone number “090-2000-1112” has already been copied to the DB 151, “migration information” is rewritten to “done”.
Since the subscriber information corresponding to the phone numbers “090-2000-1111” and “090-2000-1113” has already been copied to the DB 151, the “migration information” has been rewritten to “done”, but the access normality The “access destination information” is “DB 141b” for the reason that is not confirmed.
The subscriber information corresponding to the telephone number “090-2000-9999” is not copied to the DB 151, and “migration information” and “access destination information” are not rewritten.

(Access test)
The access test is a test for confirming whether or not the access to the subscriber information copied to the DB 151 is normal.
After the copying of all the subscriber information for which the migration process is instructed, an access test is performed on the subscriber information copied from the DB 141b to the DB 151. In response to an instruction from the operation device 160, the read / write unit 144 rewrites the migration information management table 145 and sets “access destination information” of the subscriber information to be migrated to “DB 151” as the migration destination. The normality of access is confirmed using the mobile communication terminal 110, for example. When the mobile communication terminal 110 corresponding to the subscriber information to be tested moves to an area different from the area before the migration process, the radio base station 120 that confirms the area where the mobile communication terminal 110 is located changes to the exchange 130. A location registration request is transmitted via. In response to the location registration request from the mobile communication terminal 110 of the test target user, the call processing unit 143b performs location registration on the DB 151.

At this time, if the subscriber information copy to the migration destination DB 151 is not normal, the current location information of the mobile communication terminal 110 cannot be registered. For this reason, the display of the mobile communication terminal 110 displays that the mobile communication terminal 110 is “out of range”.
If access to the migrated subscriber information is not normal by the access test, the “access destination information” of the migration information management table 145 is written back to the migration source DB 141b. The “access destination information” in the migration information management table 145 is rewritten by operating the operation device 160 according to the judgment of the maintenance person and transmitting an instruction to the read / write unit 144.

  The access test is performed on at least a part of a plurality of pieces of subscriber information for which the migration process to the DB 151 is instructed and the migration process to the DB 151 is completed. This is because when the access test is performed using the mobile communication terminal 110, it is difficult to perform the access test on all cases of a plurality of subscriber information. Further, for example, the migration processing to the DB 151 may be instructed one by one. In this case, the access test is performed on the subscriber information for which the migration process to the DB 151 has been completed.

  FIG. 4 is a flowchart showing the operation during the access test. In step S <b> 101, the read / write unit 144 rewrites “access destination information” of the subscriber information to be subjected to the access test in the migration information management table 145 to the migration destination DB 151. In step S102, the call processing unit 143b receives a location registration request via the radio base station 120 and the exchange 130 from the mobile communication terminal 110 corresponding to one of the subscriber information to be tested. In step S103, the call processing unit 143 refers to the migration information management table 145, and transmits an access request (location registration request) to the test target subscriber information held in the migration destination DB 151. Subsequently, in step S104, the call processing unit 143 receives an access response to the location registration request from the migration destination DB 151 and transmits it to the mobile communication terminal 110 corresponding to the subscriber information to be tested. In step S105, it is determined whether or not the access response to the location registration request is normal. At this time, if “out of service area” is displayed on the test mobile communication terminal 110, it is determined that the access is not normal, and if the radio wave reception level is displayed, it is determined that the access is normal. The If it is determined in step S105 that access to the migration target subscriber information held in the migration destination DB 151 is normal, the process ends. At this time, the “access destination information” for the subscriber information in the migration information management table 145 remains “DB151”. On the other hand, if it is not determined in step S105 that access to the migration target subscriber information held in the migration destination DB 151 is normal, the process proceeds to step S106. In step S106, in response to an instruction from the operation device 160, the reading / writing unit 144 writes back the “access destination information” of the subscriber information to be subjected to the access test to the migration source DB 141b, and the process ends.

(Processing of requests received from the exchange (before migration processing))
FIG. 5A is a schematic diagram showing an operation when a registration request for location information of subscriber information before the start of the migration process is received. In step S201, the call processing unit 143b receives the location registration request transmitted from the exchange 130. At this time, since it is before the start of the subscriber information migration process, it is held only in the DB 141b in which the subscriber information is held. Therefore, the process moves to step S202 without referring to the migration information management table 145. Here, a specific example of the migration information management table 145b in FIG. 5A is the migration information management table 145c in FIG. In step S202, the call processing unit 143b distributes the location registration request to the DB 141b in which the subscriber information is held. Thereafter, the “location information” of the subscriber information held in the DB 141b is rewritten.

(Processing the request received from the switch (during migration))
The subscriber information migration process is performed in parallel with the normal connection request and location registration request from the mobile terminal device. Therefore, when there is a location registration request for subscriber information during the migration process, the call processing unit 143b refers to the migration information management table 145 and accesses the access information defined by the access destination information in the migration information management table 145. Sort access requests ahead.

FIG. 5B and FIG. 5C are schematic diagrams showing an operation when a registration request for location information of subscriber information during the migration process is received. FIG. 5B shows the operation when the “access destination information” of the subscriber information requested for registration is “DB 141b” of the migration source, and FIG. 5C shows the registration request. It is the schematic which shows operation | movement in case "access destination information" of the subscriber information is "DB151" of a transfer destination.
FIG. 6 is a flowchart showing the operation of the access control management apparatus 142 when receiving a registration request for location information of subscriber information during the migration process.

  5B and 6 will be described. In step S301, the call processing unit 143b receives the location registration request transmitted from the exchange 130. In step S302, the call processing unit 143b refers to the migration information management table 145, and acquires “DB 141b” as “access destination information” of the subscriber information corresponding to the mobile communication terminal that requested the location information registration. At this time, since the subscriber information is being migrated, the subscriber information is held in both the DB 141b and the DB 151 if the migration has been completed, and is held only in the DB 141b if the migration has not been completed. . A specific example of the migration information management table 145b in FIG. 5B is the migration information management table 145d in FIG.

  In step S303, the call processing unit 143b determines that the “access destination information” of the subscriber information for which location registration is requested is “migration source DB 141b”, and distributes the location registration request to the migration source DB 141b. In step S304, the call processing unit 143b refers to the migration source DB 141b, and rewrites the “location information” of the subscriber information held in the migration source DB 141b in step S305.

  Subsequently, in step S306, the read / write unit 144 reads “location information” of the subscriber information held in the migration source DB 141b. The “position information” read at this time is the position information rewritten in step S305. In step S307, the read / write unit 144 refers to the migration destination DB 151. In step S308, it is determined whether or not the subscriber information for which location registration is requested is also stored in the migration destination DB 151. If it is determined that the subscriber information is stored, the process proceeds to step S309. In step S309, the reading / writing unit 144 rewrites the “location information” of the subscriber information held in the migration destination DB 151 with the “location information” read from the migration source DB 141b, and the process ends. In step S308, when the reading / writing unit 144 does not determine that the subscriber information for which location registration is requested is held in the migration destination DB 151, the processing is ended as it is.

  Next, FIG. 5C and FIG. 6 will be described. In step S301, the call processing unit 143b receives the location registration request transmitted from the exchange 130. In step S302, the call processing unit 143b refers to the migration information management table 145b, and acquires “DB151” as “access destination information” of the subscriber information corresponding to the mobile communication terminal that requested the location information registration. At this time, since the access destination is the DB 151, the subscriber information migration processing has been completed, and the subscriber information is held in both the DB 141b and the DB 151. A specific example of the migration information management table 145b in FIG. 5C is the migration information management table 145d in FIG. In step S303, the call processing unit 143b determines that the “access destination information” is “migration destination DB 151”, and distributes the location registration request to the migration destination DB 151. In step S314, the call processing unit 143b refers to the migration destination DB 151 and rewrites the “location information” of the subscriber information held in the migration destination DB 151 in step S315. Subsequently, in step S316, the reading / writing unit 144 reads the “location information” of the subscriber information held in the migration destination DB 151. The “position information” read at this time is the position information rewritten in step S315.

In step S307, the read / write unit 144 refers to the migration source DB 141b. In step S318, the reading / writing unit 144 rewrites the “location information” of the subscriber information held in the migration source DB 141b, and the process ends.
That is, when the call connection request subscriber information is referred to, the call processing unit 142b distributes the access request to the DB defined in the “access destination information” (hereinafter referred to as the main DB as appropriate). It is done. When subscriber information is rewritten, first, an access request is distributed to the main DB. Then, the read / write unit 144 rewrites the subscriber information held in the main DB. Subsequently, the reading / writing unit 144 reads the subscriber information (or one element such as location information constituting the subscriber information) from the main DB, and the DB not defined in the “access destination information” (hereinafter, sub-DB) Also, the subscriber information is rewritten. The main DB and the sub DB are either the migration source DB (DB 141b) or the migration destination DB (DB 151).
As a result, even when the migration source DB 141b and the migration destination DB 151 are used together as in the subscriber information migration process, the DB 141b and the DB 151 can be synchronized.

(Processing of requests received from the exchange (after completing the migration process))
FIG. 5D is a schematic diagram showing an operation when a registration request for location information of subscriber information after completion of the migration process is received. In FIG. 5D, when the call processing unit 143b receives the location information registration request from the exchange (S401), the location information registration request is distributed to the migration destination DB 151 without referring to the migration information management table 145. (Step S402). Thereafter, the “location information” of the subscriber information held in the DB 151 is rewritten. Here, a specific example of the migration information management table 145b in FIG. 5D is the migration information management table 145e in FIG.

  When all of the subscriber information held in the DB 141b that has been associated with the call processing unit 143b on a one-to-one basis is transferred to the DB 151, the association between the call processing unit 143b and the DB 141b is released. In this case, the call processing unit 143b allocates access requests to all DBs that do not have a corresponding call processing unit such as the DB 151 in consideration of the accommodation destination of subscriber information.

In addition, a request for access to subscriber information may be transmitted from the exchange 130 to the call processing unit 143b that is no longer associated with the DB 141b without being aware of the accommodation location of the subscriber information. For this reason, the call processing unit 143b may receive an access request to the subscriber information held in the DB 141a associated with the specific call processing unit 143a. Even in such a case, the call processing unit 143b distributes the access request in consideration of the accommodation destination of the subscriber information. Specifically, the call processing unit 143b distributes the access request to the subscriber information held in the DB 141a to the call processing unit 143a associated with the DB 141a. For this reason, the call processing unit 143a after the completion of the migration process holds information about the accommodation destinations of all subscriber information.
The call processing unit 143a associated with the DB 141a transmits only an access request distributed in consideration of the accommodation location of the subscriber information on the exchange 130 side, that is, an access request for the subscriber information held in the DB 141a. Is done.

(Another example of access control management apparatus and access control management method)
In the above-described embodiment, the access control management device 144 including the call processing unit 143, the read / write unit 144, and the migration information management table 145 has been described. However, the present invention is not limited to this configuration.
For example, as shown in FIG. 7, a migration information management unit 170 that manages the migration information management table 171 may be provided separately from the subscriber information management system 140. Further, the read / write unit 144 may be part of the call processing unit 143 (integrated with the call processing unit 143).
Also, the access control management method of the present invention is a subscriber to the subscriber information management device 150b from which the call processing unit is separated from the subscriber information management device 150a from which the call processing unit 143 is separated as shown in FIG. It can also be applied when transferring information.

(Other examples of migration information management table)
The migration information management table 146a shown in FIG. 9A and the migration information management table 146b shown in FIG. 9B are other examples of the migration information management table 145. Instead of the migration information management tables 145 (145c to 145e) described in FIGS. 2A to 2C, migration information management tables 146a and 146b may be used.
Another example of the migration information management table shows an example in which only a part of the subscriber information held in the DB 141b is migrated. The migration information management table 146a is created by adding an item indicating whether or not each subscriber information is “target for migration processing” to the migration information management table 145c before the migration processing shown in FIG. It is a table that was made. In the migration information management table 146a, the “migration process target” of the subscriber information (phone number band: 090-2000-1111 to 090-2000-4000) being migrated is set to “migrating process” and is not the migration process target. The “migration process target” of the subscriber information (telephone number band: 090-1000-4001 to 090-1000-9999) is set to “before the migration process is started”.

The migration information management table 146b is composed of only subscriber information that is undergoing migration processing, and is a table that manages the migration status and access destination information for subscriber information that is undergoing migration processing. The migration information management table 146b is a table that separately manages only information about subscriber information being migrated.
When the call processing unit 143 receives an access request to any of the subscriber information held in the DB 141b, the call processing unit 143 refers to the migration information management table 146a. When the “migration processing target” of the access target subscriber information is not “◯”, the call processing unit 143 distributes the access request according to the “access destination information” of the migration information management table 146a. When the “migration processing target” of the subscriber information to be accessed is “◯”, the call processing unit 143 refers to “access destination information” in the migration information management table 146b instead of the migration information management table 146a. Sort access requests.

(Modification)
The access test described in this embodiment is an example. For example, the call processing unit 143b can compare the subscriber information held in the migration source DB 141b with the subscriber information held in the migration destination DB 151 to confirm the normality of the migration of the subscriber information. .
