  In the modern society, with the progress of computerization, the amount of information processing resources (resources) such as server devices for building a social infrastructure is increasing year by year. As such information processing resources increase, there arises a problem that the power consumption of the system increases or the number of management steps for the system increases. Therefore, a technology for improving the use efficiency of information processing resources is expected.

  As an example of such a technology, Patent Document 1 discloses a virtual machine control device for the purpose of improving the use efficiency of information processing resources. This apparatus stores a table for storing performance information on a plurality of hardware resources on which a plurality of virtual machines can operate. This device measures the resource usage of hardware resources currently used by a virtual machine. After migrating the virtual machine between hardware resources, the apparatus calculates the resource usage used by the virtual machine. When the calculated resource usage after migration is smaller than the measured current resource usage, the device migrates the virtual machine between hardware resources.

  Further, Patent Document 2 discloses a virtual machine placement device for improving aggregation efficiency and preventing resource contention when a virtual machine is placed on a physical server. This apparatus extracts, as a destination physical server, a physical server for which a service interruption time generated when a virtual machine to be executed is moved is determined to be within an allowable service interruption time. If the resource usage of the physical server is expected to exceed the upper threshold, this device is used as a candidate for the virtual machine to be moved in order from the virtual machine with the highest resource usage so that the resource usage is below the upper threshold. Extract. When the resource usage of the physical server is lower than the lower threshold for a predetermined time or more, the device moves the virtual machine allocated to the physical server to another physical server.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

<First embodiment>
FIG. 1 is a block diagram conceptually showing a communication connection system 1 according to a first embodiment of the present invention. The communication connection system 1 according to the present embodiment roughly includes virtual machines 11 to 13. These virtual machines are executed by an information processing device (such as a server device) not shown. These virtual machines may be executed by the same information processing device or may be executed by different information processing devices. Note that the number of virtual machines included in the communication connection system 1 according to the present embodiment is not limited to three.

  FIG. 2 illustrates a hardware configuration of these information processing apparatuses according to the present embodiment. The execution environment described below can be adopted not only in the present embodiment but also in each embodiment described later.

The information processing device 900 illustrated in FIG. 2 includes the following as components.
CPU (Central_Processing_Unit) 901,
ROM (Read_Only_Memory) 902,
RAM (Random_Access_Memory) 903;
A hard disk (storage device) 904,
A communication interface 905 with an external device;
A bus 906 (communication line),
A reader / writer 908 capable of reading and writing data stored in a recording medium 907 such as a CD-ROM (Compact_Disc_Read_Only_Memory);
An input / output interface 909;

  That is, the information processing apparatus 900 including the above components is a general computer in which these components are connected via the bus 906.

  Then, after the virtual machines 11 to 13 are provided as computer programs, the information processing apparatus 900 reads the computer programs to the CPU 901 of the hardware, interprets and executes the computer programs. The computer program may be stored in a readable and writable volatile storage memory (RAM 903) or a nonvolatile storage device such as a hard disk 904.

  Further, in the above case, the method of supplying the computer program into the hardware can employ a general procedure at present. As the procedure, for example, there is a method of installing in the device via various recording media 907 such as a CD-ROM or a method of downloading from the outside via a communication line such as the Internet. Then, in such a case, the present invention can be considered to be constituted by a code constituting the computer program or a recording medium 907 storing the code.

  The virtual machine 11 illustrated in FIG. 1 is a communication connection that connects, for example, terminal devices 401-1 to 401-n1 (n1 is an integer of 1 or more) connected via a wireless access network to a communication network such as the Internet. Perform control. The virtual machine 12 performs communication connection control for connecting the terminal devices 402-1 to 402-n2 (n2 is an arbitrary integer of 1 or more) to a communication network such as the Internet. The virtual machine 13 performs communication connection control for connecting the terminal devices 403-1 to 403-n3 (n3 is an integer of 1 or more) to a communication network such as the Internet. The terminal device described above is, for example, a mobile phone or a tablet terminal device.

  When performing the above-described communication connection control, the virtual machines 11 to 13 use the terminal connection information on the terminal device to be controlled. The terminal communication connection information is, for example, information such as an IMSI (International Mobile Subscriber Identity), a telephone number, an IP (Internet Protocol) address, and a connection destination APN (Access Point Name).

  The virtual machine 11 realizes the terminal connection information management device 110 by executing software in a hardware environment as illustrated in FIG. The terminal connection information management device 110 can access the used storage area 115 and the unused storage area 116 arranged in the RAM 903 in the information processing apparatus 900 that executes the virtual machine 11. The in-use storage area 115 is an area in which terminal connection information regarding the terminal devices 401-1 to 401-n1 already connected to the Internet is stored. The unused storage area 116 is an unused storage area that can store terminal connection information on the terminal device when the terminal device is newly connected to the Internet by the virtual machine 11.

  Similarly to the virtual machine 11, the virtual machines 12 and 13 also implement the terminal connection information management devices 120 and 130 in order by executing software in a hardware environment as illustrated in FIG. The terminal connection information management device 120 can access the in-use storage area 125 and the unused storage area 126 arranged in the RAM 903. The terminal connection information management device 130 can access the used storage area 135 and the unused storage area 136 arranged in the RAM 903. The virtual machines 11 to 13 according to the present embodiment have equivalent functions. That is, the terminal connection information management apparatuses 120 and 130 perform the same processing as the processing performed by the terminal connection information management apparatus 110 on the virtual machine 11.

  The terminal connection information management device 110 includes a use state determination unit 111, an unused state determination unit 112, and a movement unit 113 (that is, these components are configured by hardware such as software illustrated in FIG. 2). In the environment).

  The use state determination unit 111 determines that the size of the in-use storage area 115 is equal to or smaller than the threshold indicated by the threshold information 114 at a predetermined timing (for example, at regular time intervals or when instructed by the user). It is determined whether or not. The threshold information 114 is stored in the RAM 903 of the information processing device 900. This threshold is a value set by the system administrator based on, for example, the operation results of the communication connection system 1 and the like. The use state determination unit 111 inputs the determination result to the moving unit 113.

  The unused state determination unit 112 communicates with the virtual machines 12 and 13 at the timing to determine whether the total size of the unused storage areas 126 and 136 is larger than the size of the used storage area 115. Is determined. The unused state determination unit 112 inputs the determination result to the moving unit 113. The unused state determination unit 112 also inputs the size of each of the unused storage areas 126 and 136 to the moving unit 13.

  When the size of the in-use storage area 115 is equal to or smaller than the threshold indicated by the threshold information 114 and the sum of the sizes of the unused storage areas 126 and 136 is larger than the size of the in-use storage area 115 The terminal connection information stored in the used storage area 115 is moved to the unused storage areas 126 and 136.

  At this time, the moving unit 113 distributes the terminal connection information stored in the used storage area 115 to the unused storage areas 126 and 136 according to the sizes of the unused storage areas 126 and 136. For example, when the ratio of the sizes of the unused storage areas 126 and 136 is 2: 1, the moving unit 113 allocates about two-thirds of the terminal connection information stored in the used storage area 115 to the unused storage area 115. About one third is moved to the unused storage area 136 in the used storage area 126. That is, in this case, the moving unit 113 stores the terminal connection information on (2 * n1) / 3 terminal devices among the n1 terminal devices in the unused storage area 126 and the n1 / 3 terminal devices. The terminal connection information is moved to the unused storage area 136. Here, “*” is an operator indicating multiplication, and “/” is an operator indicating division.

  After moving the terminal connection information to the unused storage areas 126 and 136, the virtual machine 11 takes over the communication connection control for the terminal devices 401-1 to 401-n1 to the virtual machines 12 and 13. For example, when the virtual machine 11 moves the terminal connection information on the terminal device 401-i (i is an integer from 1 to n1) to the unused storage area 126, the virtual machine 11 performs communication connection control on the terminal device 401-i, The virtual machine 12 takes over. The virtual machines 12 and 13 start the communication connection control after taking over the communication connection control regarding the terminal devices 401-1 to 401-n1 from the virtual machine 11.

  Next, the operation (process) of the terminal connection information management device 110 according to the present embodiment will be described in detail with reference to the flowchart of FIG.

  The use state determination unit 111 determines whether the size of the in-use storage area 115 is equal to or smaller than the threshold indicated by the threshold information 114 at a predetermined timing (step S101). If the size of the in-use storage area 115 is not equal to or smaller than the threshold (No in step S102), the process returns to step S101. If the size of the used storage area 115 is equal to or smaller than the threshold (Yes in step S102), the unused state determination unit 112 determines that the sum of the sizes of the unused storage areas 126 and 136 is equal to the size of the used storage area 115. It is determined whether it is larger than the threshold value (step S103).

  If the total size of the unused storage areas 126 and 136 is not larger than the size of the used storage area 115 (No in step S104), the process returns to step S101. If the sum of the sizes of the unused storage areas 126 and 136 is larger than the size of the used storage area 115 (Yes in step S104), the moving unit 113 connects the terminal connection stored in the used storage area 115. The information is moved to the unused storage areas 126 and 136, and the entire process ends.

The terminal connection information management device 110 according to the present embodiment can prevent a situation in which the use efficiency of the information processing resources is reduced from occurring in the communication connection system with a simple configuration. The reason is that the terminal connection information management device 110 operates as follows. That is,
The use state determination unit 111 determines whether the size of the in-use storage area 115 is equal to or smaller than a threshold.
The unused state determination unit 112 determines whether the total size of the unused storage areas 126 and 136 is larger than the size of the used storage area 115.
The moving unit 113 determines that the size of the used storage area 115 is equal to or smaller than the threshold indicated by the threshold information 114, and the sum of the sizes of the unused storage areas 126 and 136 is larger than the size of the used storage area 115. If it is larger, the terminal connection information stored in the used storage area 115 is moved to the unused storage areas 126 and 136.

  Hereinafter, effects realized by the terminal connection information management device 10 according to the present embodiment will be described in detail.

  A communication connection system that connects a terminal device such as a mobile phone to a communication network such as the Internet generally includes a plurality of information processing devices that perform communication connection control. In such a communication connection system, the number of terminal devices to be controlled by each information processing device greatly varies with time. As a result, there may be a case where an information processing apparatus that is larger than the number of information processing apparatuses originally required for performing the communication connection control is in a state of performing the communication connection control. The occurrence of such a state is not preferable from the viewpoint of the use efficiency of information processing resources. Therefore, in a communication connection system, it is required to avoid a situation in which the use efficiency of information processing resources is reduced by a simple configuration.

  In such a background, in the terminal connection information management device 110 according to the present embodiment, as described above, the use state determination unit 111 determines whether the size of the in-use storage area 115 is equal to or smaller than the threshold indicated by the threshold information 114. It is determined whether or not it is (step S101). The unused state determination unit 112 determines whether the total size of the unused storage areas 126 and 136 is larger than the size of the used storage area 115 (step S103). When the size of the used storage area 115 is equal to or smaller than the threshold value and the sum of the sizes of the unused storage areas 126 and 136 is larger than the size of the used storage area 115, the moving unit 113 stores the used storage area. The terminal connection information stored in the area 115 is moved to the unused storage areas 126 and 136 (step S105). Since the virtual machines 12 and 13 have a function of performing communication connection control for connecting the terminal device to the Internet, the terminal devices associated with the terminal connection information moved from the virtual machine 11 can be quickly disconnected without disconnecting the communication. Can take over the communication connection control. At this time, the communication connection control is centralized in the virtual machines 12 and 13, so that the virtual machine 11 can intensively perform another process other than the communication connection control. That is, in this case, the use efficiency of the information processing resources in the communication connection system 1 is improved. Therefore, the terminal connection information management device 110 according to the present embodiment can prevent the occurrence of a state in which the use efficiency of the information processing resources is reduced in the communication connection system with a simple configuration.

  Further, the terminal connection information management apparatus 110 according to the present embodiment performs communication connection control performed by the virtual machine 11 on the basis of the fact that the size of the in-use storage area 115 is equal to or smaller than the threshold indicated by the threshold information 114. The opportunity to consolidate to. Accordingly, the terminal connection information management device 110 according to the present embodiment can centralize the communication connection control performed by the virtual machine 11 in the virtual machines 12 and 13 without missing an appropriate timing. Note that the threshold represented by the threshold information 114 does not have to be a fixed value, and may be, for example, a fluctuation value that varies depending on a time zone or the like. Alternatively, the use state determination unit 111 according to the present embodiment may determine, for example, whether a time-series change regarding the size of the in-use storage area 115 satisfies a predetermined criterion.

  Further, the moving unit 13 according to the present embodiment converts the terminal connection information stored in the used storage area 115 into the unused storage areas 126 and 136 according to the size of each of the unused storage areas 126 and 136. Distribute to Accordingly, the terminal connection information management device 110 according to the present embodiment can prevent the load related to the communication connection control from being biased to one of the virtual machines 12 and 13 that has taken over the communication connection control from the virtual machine 11.

  Further, the unused state determination unit 112 according to the present embodiment may determine whether any of the unused storage areas 126 and 136 is larger than the used storage area 115. In this case, the moving unit 113 stores the terminal connection information stored in the used storage area 115 in one of the unused storage areas 126 and 136 whose size is determined to be larger than the size of the used storage area 115. To move. Accordingly, the terminal connection information management device 110 according to the present embodiment uses the information processing resources with a simpler configuration than when distributing the terminal connection information according to the size of each of the unused storage areas 126 and 136. It is possible to avoid a state in which the efficiency is reduced. Alternatively, the unused state determination unit 112 according to the present embodiment may determine whether the size of the unused storage areas 126 and 136 is larger than the size of the used storage area 115 by a predetermined value or more. .

  Note that the communication connection system 1 according to the present embodiment may include, instead of the virtual machines 11 to 13, real machines that realize the same functions as those virtual machines. In this case, the use state determination unit 111, the unused state determination unit 112, and the movement unit 113 may be electronic circuits, or may be realized by a computer program and a processor that operates according to the computer program.
