Then, the communication server generates an image on behalf of the client device in response to an image generation request from each communication terminal.

JP 2002-223332 A

  However, the conventional server system described above has the following problems. In other words, when the communication server receives an image generation request, even if the calculation processing is simple enough to be processed on the communication terminal side or when there is a margin for the calculation processing on the communication terminal side, the communication server is uniformly substituted. Processing will be performed. For this reason, there are cases where the processing resources in the server system cannot be used effectively.

  Therefore, the present invention has been made to solve the above-described problems, and an object of the present invention is to provide a server system in which arithmetic processing resources are effectively used, a communication terminal used for the server system, and a communication server.

  The communication server according to the present invention is a communication server that transmits processing information to be processed to the communication terminal, and the processing load status of the communication terminal when processing the processing information repeatedly sent from the communication terminal And an instruction generation unit that generates a proxy instruction according to the calculation load status, and receives the proxy instruction generated by the command generation unit, and processing information to be transmitted to the communication terminal based on the received proxy instruction A proxy processing means for performing arithmetic processing on behalf of the communication terminal, and processing result transmission means for transmitting processing information calculated by the proxy processing means to the communication terminal. .

Then, the proxy processing means performs processing of the processing information to be transmitted to the communication terminal based on different proxy instructions, and the processing result transmission means transmits the result of the processing information subjected to the calculation processing to the communication terminal. The communication terminal receives the processing information that has been processed. That is, since the instruction generation unit can generate the proxy instruction according to the calculation load situation, the degree of the proxy calculation process in the proxy processing unit can be changed flexibly, so that the calculation processing resources such as the calculation element of the communication terminal Can be used effectively.

  The instruction generation unit generates a proxy instruction only when the computation load situation sent from the communication terminal exceeds a predetermined load situation, and the proxy processing unit accepts the proxy instruction generated by the instruction generation unit. In this case, it is preferable to perform arithmetic processing instead of the communication terminal. In this case, since the proxy processing means performs the proxy calculation process only when the proxy processing of the communication terminal is necessary, it is possible to significantly avoid the proxy calculation process when the necessity is low.

  Moreover, it is preferable that an instruction | indication production | generation means receives the load factor of the arithmetic element of a communication terminal as a calculation load condition of a communication terminal, and produces | generates the substitute instruction | indication according to this load factor.

  A server system according to the present invention is a server system that includes a communication terminal and a communication server that is communicable with the communication terminal and transmits processing information to be processed with respect to the communication terminal.

  In this server system, when the detection means repeatedly detects the calculation load situation of the communication terminal, the instruction generation means generates a substitute instruction according to the calculation load situation. For this reason, the instruction generation unit can generate different proxy instructions depending on whether the communication terminal is performing an overload calculation process and the communication terminal has a sufficient calculation process. Then, the proxy processing means performs processing of the processing information to be transmitted to the communication terminal based on different proxy instructions, and the processing result transmission means transmits the result of the processing information subjected to the calculation processing to the communication terminal. The communication terminal receives the processing information that has been processed. That is, the instruction generation unit generates a proxy instruction according to the calculation load situation, so that the degree of the proxy calculation process in the proxy processing unit can be flexibly changed. Therefore, in this server system, it is possible to effectively use arithmetic processing resources such as arithmetic elements of the communication terminal.

  The instruction generation unit generates a proxy instruction only when the calculation load status detected by the detection unit exceeds a predetermined load status, and the proxy processing unit accepts the proxy instruction generated by the command generation unit. In some cases, it is preferable to perform arithmetic processing instead of the communication terminal. In this case, since the proxy processing means performs the proxy calculation process only when the proxy processing of the communication terminal is necessary, it is possible to significantly avoid the proxy calculation process when the necessity is low.

  Moreover, it is preferable that a detection means detects the load factor of the calculation element of a communication terminal as a calculation load condition of a communication terminal.

  A server system according to the present invention is a server system including a plurality of communication terminals and a communication server that is communicable with the communication terminals and transmits processing information to be processed for each communication terminal. A detection unit that repeatedly detects the calculation load status of each communication terminal when processing the processing information received from the server, a comparison unit that compares the calculation load status of each communication terminal detected by the detection unit, and a comparison unit Of the processing information to be transmitted to the first communication terminal, the instruction generation unit generates a proxy instruction according to the calculation load status of the first communication terminal determined to have a large load.

It is characterized by that.

  In this server system, when the detection means repeatedly detects the calculation load status of each communication terminal, the comparison means compares the calculation load status detected by the detection means. And the instruction | indication production | generation means produces | generates the substitute instruction | indication according to the calculation load condition of the 1st communication terminal judged with the load being large by the comparison means. Therefore, the instruction generation unit may generate different proxy instructions depending on whether the overload calculation process is performed in the first communication terminal and the calculation process of the first communication terminal has a margin. it can. Then, the proxy requesting means sends the processing information of the parts corresponding to the different proxy instructions to the second communication terminal determined to have a low load by the comparing means. Subsequently, the proxy processing means performs processing of the processing information sent from the proxy requesting means, and the processing result transmitting means transmits the result of the processing information subjected to the calculation processing to the first communication terminal. Thus, the first communication terminal receives the processed processing information. That is, the instruction generation unit generates a proxy instruction according to the calculation load status of the first communication terminal, so that the degree of the proxy calculation process in the proxy processing unit can be flexibly changed. Therefore, in this server system, it is possible to effectively use arithmetic processing resources such as arithmetic elements of the first communication terminal.

  This communication terminal repeatedly detects the calculation load status of the proxy communication terminal and accepts a proxy instruction from a communication server that generates a proxy instruction according to the calculation load status. This proxy instruction is different depending on whether an overload calculation process is performed at the communication terminal or when there is a margin in the calculation process. Then, the proxy processing means performs calculation processing of processing information to be transmitted to the proxy communication terminal based on different proxy instructions, and the processing result transmission means outputs the result of the processing information calculated to the proxy communication terminal.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, a server system according to the present invention, a communication terminal used for the server system, and a communication server and a form considered to be best will be described in detail with reference to the accompanying drawings. In addition, the same code | symbol is attached | subjected about the same or equivalent element, and the description is abbreviate | omitted when description overlaps.

(First embodiment)
As shown in FIG. 1, the server system 1A according to the first embodiment includes a communication server 10A connected to the Internet NT and a communication terminal 20A. The server system 1A is a system for providing various services using a communication terminal to a user, for example, installed on a vehicle such as a large vehicle or a ship, and provides services such as access to the Internet and games. Is done.

  The communication server 10A mainly includes an information processing device including a computing element (for example, a CPU), a storage device such as a memory and a hard disk, and a wireless communication device as physical components. Further, the communication server 10A includes, as functional components, a processing information transmission unit 11, a load factor detection unit 12 (detection unit), an instruction generation unit 13 (instruction generation unit), a proxy processing unit 14 (substitute processing unit), A processing result transmission unit 15 (processing result transmission means) is provided.

  The processing information transmission unit 11 is a part that transmits processing information necessary for providing the service to the communication terminal 20A. The communication terminal 20A that has received the processing information performs various arithmetic processes according to the processing information. This is done using the CPU. The processing information is, for example, a source program for displaying characters on the communication terminal 20A (hereinafter referred to as a character source) and a source program for displaying images on the communication terminal 20A (hereinafter referred to as an image source). ), A source program (hereinafter referred to as an audio source) for outputting sound from the communication terminal 20A.

  The load factor detection unit 12 is a part that detects a load factor (calculation load status) of the CPU of the communication terminal 20A at a fixed period in the communication server 10A using a known communication protocol. This load factor is a CPU operating rate calculated based on the maximum arithmetic processing capability of the CPU, and the larger the load factor is, the larger the processing load is applied to the CPU. The CPU operating rate can be obtained from a CPU operating signal output when the CPU is operating. The CPU operating rate can also be calculated from the ratio of execution / pause when writing predetermined data using software.

  The instruction generation unit 13 generates a substitute instruction according to the load factor of the CPU of the communication terminal 20 </ b> A detected by the load factor detection unit 12. In addition, the proxy processing unit 14 performs a calculation process for a part of information transmitted from the processing information transmission unit 11 to the communication terminal 20 </ b> A based on the proxy instruction generated by the instruction generation unit 13. Here, the substitute instruction generated by the instruction generation unit 13 is instruction information indicating the degree of the substitution calculation process performed by the substitution processing unit 14.

  Here, the proxy instruction will be described in more detail by taking as an example a case where a character source, an image source, and a sound source are transmitted from the processing information transmitting unit 11 to the communication terminal 20A as processing information to be subjected to arithmetic processing. When the load factor of the CPU of the communication terminal 20A is low, the instruction generation unit 13 generates instruction information that substitutes for arithmetic processing of a character source with a relatively low load on the CPU as a substitute instruction. In this case, the proxy processing unit 14 performs the arithmetic processing of the character source in the information transmitted from the processing information transmitting unit 11 to the communication terminal 20A based on the proxy instruction. On the other hand, when the load factor of the CPU of the communication terminal 20A is high, the instruction generation unit 13 generates instruction information that substitutes for arithmetic processing of an image source and an audio source that impose a heavy load on the CPU. In this case, the proxy processing unit 14 performs the arithmetic processing of the image source and the audio source in the information transmitted from the processing information transmitting unit 11 to the communication terminal 20A based on the proxy instruction.

  The processing result transmission unit 15 obtains, as an arithmetic processing result, character information obtained as a result of the arithmetic processing of the character source, image information obtained as a result of the arithmetic processing of the image source, and a result of the arithmetic processing of the audio source. The received voice information is transmitted to the communication terminal 20A.

  The communication terminal 20A mainly includes, as physical components, an information processing device including an arithmetic element (for example, a CPU), a storage device such as a memory and a hard disk, a display unit such as a liquid crystal display, a microphone, a speaker, and a wireless communication device. It has. Further, the communication terminal 20A includes an arithmetic processing unit 21 and a processing result receiving unit 22 as functional components.

  The arithmetic processing unit 21 is a part that receives the above-described character source or the like sent from the processing information transmitting unit 11 of the communication server 10A as processing information to be processed and performs arithmetic processing of the processing information. Moreover, the process result receiving part 22 is a part which receives the calculation process result transmitted from the process result transmission part 15 of 10 A of communication servers mentioned above.

  Next, the proxy process in the server system 1A described above will be described with reference to the flowchart of FIG.

  When the load factor of the communication terminal 20A is detected by the load factor detector 12 of the communication server 10A (S10), an instruction generation unit 13 generates a substitute instruction according to the load factor detected by the load factor detector 12 (S12). When the substitution instruction is generated by the instruction generation unit 13, a part of the processing information transmitted from the processing information transmission unit 11 to the communication terminal 20A is arithmetically processed by the substitution processing unit 14 based on the substitution instruction (S14). . Then, the calculation processing result processed by the proxy processing unit 14 is transmitted from the processing result transmitting unit 15 to the communication terminal 20A (S16). The communication terminal 20A accepts the arithmetic processing result sent from the processing result transmission unit 15 of the communication server 10A by the processing result receiving unit 22 (S18), and the arithmetic processing unit 21 receives the sent arithmetic processing result. The calculated processing information is reflected in the calculation processing result (S20).

  As described in detail above, in the server system 1A, the instruction generation unit 13 of the communication server 10A has a high load factor when the load factor of the CPU detected by the load factor detection unit 12 at a certain period is low. In some cases, different proxy instructions are generated, and the proxy processing unit 14 performs proxy calculation processing based on the proxy instructions. Therefore, when the CPU of the communication terminal 20A transitions from a state where the processing load is hardly applied to an overload state, or conversely, the CPU of the communication terminal 20A transitions from an overload state to a state where the processing load is hardly applied. Even in this case, the degree of the substitution calculation process in the substitution processing unit 14 changes flexibly. Therefore, in the server system 1A, effective use of arithmetic processing resources such as the CPU of the communication terminal 20A is realized.

  The instruction generation unit 13 may generate the proxy instruction described above only when the communication terminal 20A has a predetermined load factor (for example, 0.8) or more. That is, since the instruction generation unit 13 generates a substitution instruction when a certain threshold value is exceeded, the substitution processing unit 14 performs the substitution calculation process only when the substitution calculation process of the communication terminal 20A is necessary. It is possible to avoid proxy processing when there is a shortage.

  Here, in a conventional server system including a plurality of communication terminals, when there is a proxy request from a plurality of communication terminals, a great load is placed on the communication server. There was a need for more processing power than necessary. On the other hand, in this server system 1A, even when the number of communication terminals 20A is increased as appropriate, the proxy processing unit 14 of the communication server 10A flexibly changes the degree of proxy calculation processing, and therefore, more processing than necessary. There is no need to prepare a communication server having the capability.

(Second Embodiment)
Next, a server system 1B according to the second embodiment will be described with reference to FIG.

  The server system 1B includes a communication server 10B and a communication terminal 20B. The communication server 10B includes, as functional components, a processing information transmission unit 11, an instruction generation unit 13, a proxy processing unit 14, a processing result transmission unit 15, and a load factor reception unit 16, and the communication terminal 20B A processing unit 21, a processing result receiving unit 22, a load factor detecting unit 23, and a load factor transmitting unit 24 are provided. That is, the communication server 10B is different from the communication server 10A only in that it includes a load factor receiving unit 16 instead of the load factor detecting unit 12, and the communication terminal 20B includes a load factor detecting unit 23 and a load factor transmitting unit 24. Is different from the communication terminal 20A only.

  The load factor detection unit 23 of the communication terminal 20B is a part having substantially the same function as the load factor detection unit 12 of the communication server 10A described above, and detects the load factor of the CPU of its own communication terminal 20B at a constant cycle. . The load factor transmission unit 24 of the communication terminal 20B is a part that transmits the load factor detected by the load factor detection unit 23 to the communication server 10B. Furthermore, the load factor receiving unit 16 of the communication server 10B is a part that receives the load factor sent from the load factor transmitting unit 24 of the communication terminal 20B. Note that the instruction generation unit 13 in the communication server 10B generates a substitute instruction according to the load factor received by the load factor reception unit 16.

  The proxy process in the server system 1B will be described with reference to the flowchart of FIG.

  When the load factor of the communication terminal 20B is detected by the load factor detector 23 of the communication terminal 20B (S30), the detected load factor is transmitted to the communication server 10B by the load factor transmitter 24 (S32). The communication server 10B receives the load factor transmitted from the load factor transmitting unit 24 of the communication terminal 20B by the load factor receiving unit 16 (S34). Then, the instruction generation unit 13 generates a substitute instruction according to the load factor received by the load factor receiver 16 (S36). When the proxy instruction is generated by the instruction generator 13, a part of the processing information transmitted from the processing information transmitter 11 to the communication terminal 20B is calculated by the proxy processor 14 based on the proxy instruction (S38). . Then, the calculation processing result processed by the proxy processing unit 14 is transmitted from the processing result transmitting unit 15 to the communication terminal 20B (S40). The communication terminal 20B receives the calculation processing result sent from the processing result transmission unit 15 of the communication server 10B by the processing result receiving unit 22 (S42), and the calculation processing unit 21 receives the calculation processing result sent thereto. The calculation processing result is reflected in the calculation processing result (S44).

  As described above, also in the server system 1B, as in the server system 1A, the instruction generation unit 13 of the communication server 10B is detected by the load factor detection unit 23 of the communication terminal 20B at a constant cycle. Different proxy instructions are generated depending on whether the load is low or the load factor is high, and the proxy processing unit 14 performs proxy calculation processing based on the proxy instructions. Therefore, since the degree of the substitution calculation processing in the substitution processing unit 14 changes flexibly, the server system 1B also realizes effective use of calculation processing resources such as the CPU of the communication terminal 20B.

(Third embodiment)
Next, a server system 1C according to the third embodiment will be described with reference to FIG.

  The server system 1C includes a communication server 10C, a communication terminal 20C, and a communication terminal 30C. The physical components of the communication terminal 30C are the same as those of the communication terminal 20A described above.

  The communication server 10C includes, as functional components, a processing information transmission unit 11, a load factor detection unit 12, an instruction generation unit 13, a comparison unit 17 (comparison unit), a substitution request unit 18 (substitution request unit), and a transfer. The communication terminal 20 </ b> C and the communication terminal 30 </ b> C include an arithmetic processing unit 21, a processing result receiving unit 22, a proxy processing unit 25, and a processing result transmitting unit 26. That is, the communication server 10C differs from the communication server 10A only in that it includes a comparison unit 17, a substitution request unit 18, and a transfer unit 19 instead of the substitution processing unit 14 and the processing result transmission unit 15, and the communication terminal 20C and the communication terminal 30C. Is different from the communication terminal 20 </ b> A only in that the proxy processing unit 25 and the processing result transmission unit 26 are provided.

  The load factor detection unit 12 in the server system 1C detects the load factors of both the communication terminal 20C and the communication terminal 30C. Then, the comparison unit 17 compares the load factor of the communication terminal 20C detected by the load factor detection unit 12 with the load factor of the communication terminal 30C. Hereinafter, for convenience of explanation, the communication terminal whose load factor is determined to be larger by the comparison unit 17 is determined as the first communication terminal 20C (substitute communication terminal), and the load factor is determined to be smaller by the comparison unit 17. One communication terminal will be described as the second communication terminal 30C.

  The instruction generation unit 13 generates a proxy instruction according to the load factor of the first communication terminal 20C. The proxy requesting unit 18 transmits the processing information of the part corresponding to the proxy instruction generated by the instruction generating unit 13 among the processing information to be transmitted from the communication server 10C to the first communication terminal 20C, to the second communication terminal 30C. Send against.

  The proxy processing unit 25 of the communication terminal 20C and the communication terminal 30C is a part having substantially the same function as the proxy processing unit 14 of the communication server 10A described above, and processing information sent from the proxy request unit 18 of the communication server 10C. Performs the substitute operation processing. The processing result transmission unit 26 is a part that sends the arithmetic processing result processed by the proxy processing unit 25 to the communication terminal 20C (or the communication terminal 30C) via the communication server 10C.

  In addition, the transfer unit 19 of the communication server 10C is a part that transfers a calculation processing result sent from the first communication terminal 20C to the second communication terminal 30C.

  In the server system 1C, a proxy process in which the second communication terminal 30C performs the calculation process of the first communication terminal 20C will be described with reference to the flowchart of FIG.

  When the load factors of the communication terminal 20C and the communication terminal 30C are detected by the load factor detector 12 of the communication server 10C (S50), the comparator 17 compares the load factors of both the communication terminals 20C and 30C (S52). ). Then, the instruction generation unit 13 generates a proxy instruction according to the load factor of the first communication terminal 30C having the smaller load factor (S54), and among the processing information of the first communication terminal 20C, Processing information corresponding to the proxy instruction is sent to the second communication terminal 30C by the proxy request unit 18 (S56). The processing information sent from the proxy request unit 18 to the second communication terminal 30C is processed by the proxy processing unit 25 (S58), and the processing result transmission unit 26 of the second communication terminal 30C passes through the communication server 10C. It is sent to the first communication terminal 20C (S60). The first communication terminal 20C receives the calculation processing result sent from the transfer unit 19 of the communication server 10C by the processing result receiving unit 22 (S62), and receives the sent calculation processing result as the calculation processing unit 21. Is reflected in the calculation processing result of the processing information calculated by (S64).

  As described above, also in the server system 1C, as in the server system 1A and the server system 1B, the instruction generation unit 13 of the communication server 10C is periodically transmitted by the load factor detection unit 23 of the first communication terminal 20C. Different proxy instructions are generated depending on whether the detected load factor of the CPU is low or high, and processing information of a part corresponding to the proxy instruction is substituted by the proxy processing unit 25 of the second communication terminal 30C. Arithmetic processing is performed. Accordingly, since the degree of the proxy calculation process of the second communication terminal 30C that performs the proxy calculation process of the first communication terminal 20C changes flexibly, the calculation of the CPU of the first communication terminal 20C and the like also in the server system 1C. Effective use of processing resources is realized.

  Note that the instruction generation unit 13 of the communication server 10C may generate the proxy instruction described above only when the communication terminal 20C has a predetermined load factor (for example, 0.8) or more. At this time, the proxy request unit 18 sends processing information to the second communication terminal 30C when the proxy instruction is generated by the instruction generation unit 13, and the proxy processing unit 25 of the second communication terminal 30C When processing information is sent from the proxy requesting unit 18, the calculation processing is performed instead of the first communication terminal 20C. In this case, since the proxy processing unit 25 of the second communication terminal 30C performs the proxy calculation process only when the proxy calculation process of the first communication terminal 20C is necessary, the proxy calculation process when there is little necessity is significantly performed. It can be avoided.

  Further, in this server system 1C, the second communication terminal 30C acts as a substitute for the arithmetic processing of the first communication terminal 20C with a larger load, so that the communication processing capacity of the CPU of the communication server 10C is low, Even when the CPU of the server 10C is in an overload state, the communication processing can be performed between the communication terminals 20C and 30C. Note that, since the communication terminal 20C and the communication terminal 30C have the same configuration with respect to physical components and functional components, it goes without saying that one can perform the other proxy calculation processing as necessary. Nor. Moreover, the server system 1C can also add the communication terminal similar to the communication terminal 20C and the communication terminal 30C suitably.

To detect. Moreover, the load factor transmission part 24 of communication terminal 20D, 30D is a part which transmits the load factor detected by the load factor detection part 23 with respect to the communication server 10B. Furthermore, the load factor receiving unit 16 of the communication server 10D is a part that receives the load factor transmitted from the load factor transmitting unit 24 of the communication terminal 20D and the communication terminal 30D. The comparison unit 17 in the communication server 10D compares the load factor of the communication terminal 20D received by the load factor reception unit 16 with the load factor of the communication terminal 30D.

  In the server system 1D, a proxy process in which the second communication terminal 30D performs the calculation process of the first communication terminal 20D will be described with reference to the flowchart of FIG. For convenience of explanation, the communication terminal whose load factor is determined to be larger by the comparison unit 17 of the communication server 10D is the first communication terminal 20D (substitute communication terminal), and the load factor is smaller by the comparison unit 17. The communication terminal that is determined as “second communication terminal 30D” will be described.

  When the load factor of each communication terminal 20D, 30D is detected by the load factor detector 23 of each communication terminal 20D, 30D (S70), the detected load factor is transmitted to the communication server 10D by the load factor transmitter 24. (S72). When the communication server 10D receives the load factor transmitted from the load factor transmission unit 24 of the communication terminal 20D and the communication terminal 30D by the load factor reception unit 16 (S74), the comparison unit 17 causes both communication terminals 20D and 30D to be received. Are compared (S76). Then, the instruction generation unit 13 generates a proxy instruction according to the load factor of the first communication terminal 30D having the smaller load factor (S78), and among the processing information of the first communication terminal 20D, Processing information corresponding to the proxy instruction is sent to the second communication terminal 30D by the proxy request unit 18 (S80).

  The processing information sent from the proxy request unit 18 to the second communication terminal 30D is processed by the proxy processing unit 25 (S82), and the processing result transmission unit 26 of the second communication terminal 30D passes through the communication server 10D. It is sent to the first communication terminal 20D (S84). The first communication terminal 20D receives the calculation processing result sent from the transfer unit 19 of the communication server 10D by the processing result receiving unit 22 (S86), and receives the sent calculation processing result as the calculation processing unit 21. Is reflected in the calculation processing result of the processing information calculated by (S88).

  As described above, also in the server system 1D, as in the server system 1C, the instruction generation unit 13 of the communication server 10D is a CPU that is detected at a constant cycle by the load factor detection unit 23 of the first communication terminal 20D. Different proxy instructions are generated when the load factor is low and when the load factor is high, and the processing information of the part corresponding to the proxy instruction is subjected to proxy calculation processing by the proxy processing unit 25 of the second communication terminal 30D. . Accordingly, since the degree of the proxy calculation process of the second communication terminal 30D that performs the proxy calculation process of the first communication terminal 20D changes flexibly, the calculation of the CPU of the first communication terminal 20D and the like also in the server system 1D Effective use of processing resources is realized.

  Also in this server system 1D, similarly to the server system 1C, the second communication terminal 30D performs the arithmetic processing of the first communication terminal 20D with a larger load, so that the arithmetic processing capability of the CPU of the communication server 10D Even if the CPU is low or the CPU of the communication server 10D is in an overloaded state, the communication processing can be performed between the communication terminals 20D and 30D. Note that, since the communication terminal 20D and the communication terminal 30D have the same configuration with respect to physical components and functional components, it goes without saying that one can perform the proxy operation processing of the other as necessary. Nor. Moreover, the server system 1D can also add the communication terminal similar to the communication terminal 20D and the communication terminal 30D suitably.

  The present invention is not limited to the above embodiment, and various modifications are possible. For example, the communication between the server and the communication terminal is not limited to wireless and may be wired. Further, the calculation load status of the communication terminal can be defined not only by the CPU load factor but also by the usage rate of the allowable CPU resource assigned to each application used in the communication terminal. Furthermore, the instruction generation unit is not necessarily on the communication server side, and may be on the communication terminal side.
