Description

  The present invention relates to a technique for transferring data transmitted and received between communication carriers.

  In communication for interconnecting communication carriers, not only data but also media data transfer processing such as audio and video data is important. However, there are a plurality of encoding methods for communication of media data, and the encoding method adopted by each communication carrier is not unified.

  In particular, in communication such as audio / video data, there is no codec unified among communication carriers, and each communication provider provides a media data communication service by an arbitrary encoding method. For example, as shown in FIG. 9, the communication carrier A adopts AMR (Adaptive Multi-Rate), and the communication carrier B uses ITU-T (International Telecommunication Union Telecommunication Standardization Sector) G. It is assumed that 711 is adopted. In this case, in order to connect the users of the communication carrier A and the communication carrier B, it is necessary to perform codec conversion at a connection point (POI: Point Of Interface).

  FIG. 10 shows a general communication system for connecting communication carriers in such media data communication. A general communication system includes a transfer control device and a transfer processing device. The transfer control device is, for example, a SIP (Session Initiation Protocol) server. The transfer processing device is, for example, a media gateway. The communication system connects communication terminal A and communication terminal B. The communication terminal A is a terminal that uses the communication carrier A. The communication terminal B is a terminal that uses the communication carrier B. The transfer processing device is provided with a media processing unit. The media processing unit is configured by, for example, a DSP (digital signal processor). The media processing unit performs transmission / reception processing and digital processing on information including the encoded media data. The transfer control device identifies the communication terminal A and the communication terminal B in the session establishment process. Here, when the codec is different between the communication terminals, the transfer control device issues a transfer instruction with codec conversion to the transfer processing device. On the other hand, if the codecs between the communication terminals match, the transfer control device issues a transfer instruction without codec conversion to the transfer processing device. As a result, the communication system realizes a media data communication service between communication carriers adopting different encoding methods. Generally, the transfer processing device operates in accordance with instructions from the transfer control device. In general, the transfer control device monitors the status of resources in the transfer processing device.

  FIG. 11 is a schematic diagram illustrating transmission / reception processing and digital processing of the transfer processing device. First, the transfer processing device extracts encoded data from reception information and starts reception processing for absorbing fluctuations and delays by a jitter buffer. After that, when codec conversion is necessary, the transfer processing device performs digital processing for decoding the extracted encoded data using the transmission source codec and encoding it according to the transmission destination codec. Then, after assembling the encoded data as transmission information, the transfer processing device performs transmission processing for transmitting the transmission information to the transmission destination.

  An example of a technique related to media data communication between such communication carriers is described in Patent Document 1. In the communication system described in Patent Document 1, when the originating side codec and the terminating side codec are the same, and the carrier of the relay network is a codec that allows connection, the originating side codec and the originating side codec Determine the destination codec. As a result, this related technology does not perform useless codec conversion while guaranteeing connectivity between various carriers.

JP2013-12856A

  Here, in the transfer processing apparatus in the communication system that connects the communication carriers as described above, the performance is required to increase with the increase in users. However, the related art described above has the following problems when enhancing performance.

  When enhancing the performance of a general transfer processing device, a media processing unit is added to the transfer processing device as shown in FIG. As described above, the media processing unit is often configured with dedicated hardware such as a DSP. For this reason, when enhancing the performance of a general transfer processing apparatus, it is necessary to add new hardware. That is, in this case, capital investment and actual work of adding hardware are required each time performance is increased. Furthermore, work such as additionally registering a new media processing unit occurs in the transfer control device. As described above, a general transfer processing apparatus has a problem that new equipment investment and local adjustment work are required for performance enhancement.

  Furthermore, a general transfer processing device has a problem that the resources of the media processing unit cannot be fully utilized. Here, as shown in FIG. 13A, in a media processing unit such as a DSP, in general, resources used for transmission / reception processing and resources used for digital processing are respectively fixedly mapped. However, in a media processing unit such as a DSP, the amount of resources used for digital processing differs depending on the type of encoding (codec). For example, ITU-T G.I. Compared to the digital processing related to 711, the amount of resources required for digital processing related to AMR and EVRC (enhanced variable rate codec) is large. For this reason, the performance of the transfer processing device is determined based on a codec with a large resource usage. For example, most telecommunications carriers used by communication terminals that actually relay are ITU-T G.264. Even when 711 is adopted, it is necessary to set the performance value of the transfer processing device assuming that codec conversion such as AMR / EVRC with a large resource usage is performed. In this case, as shown in FIG. 13B, there is a problem in that useless resources that are not actually consumed are generated.

  Further, in Patent Document 1, although the codec conversion is not necessary when the codec is the same on the calling side and the called side and the processing cost is reduced, the problem regarding the waste of resources that occurs in that case is as follows. There is no description.

  The present invention has been made to solve the above-described problems. That is, the present invention relates to a transfer processing apparatus that relays communication of encoded data transmitted and received between communication carriers, and a technique for further improving resource use efficiency while reducing work costs related to performance enhancement. The purpose is to provide.

  The transfer processing apparatus according to the present invention uses a resource allocated to a processor group to perform a transfer process on received information including encoded data, and an encoding transmitted / received between communication carriers. Reception that receives information including data, determines the transfer processing content based on the encoding scheme of the transmission source and the transmission destination of the received information, and causes the encoded data processing unit to execute the determined transfer processing content An information processing unit, and a resource control unit that adjusts an amount of each of the resources allocated for the transmission / reception processing and the digital processing based on a use situation of the resource regarding each of the transmission / reception processing and digital processing in the transfer processing; .

  Also, the transfer processing method of the present invention receives information including encoded data transmitted / received between telecommunications carriers, and details of transfer processing based on the encoding scheme of the source of the received information and the encoding scheme of the destination The transfer processing content determined for the received information is executed using the resources allocated to the processor group, and based on the use status of the resources for each of the transmission / reception processing and digital processing in the transfer processing Then, the amount of each of the resources allocated for the transmission / reception processing and the digital processing is adjusted.

  Further, the transfer processing program of the present invention is based on a reception step for receiving information including encoded data transmitted / received between telecommunications carriers, an encoding scheme of a transmission source of the received information, and an encoding scheme of a transmission destination A transfer process determining step for determining the transfer process contents, a transfer process step for executing the transfer process contents determined for the received information using a resource allocated to the processor group, a transmission / reception process in the transfer process, and Based on the use status of the resource regarding each of the digital processing, the computer apparatus is caused to execute a resource control step of adjusting an amount allocated for the transmission / reception processing and the digital processing among the resources.

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

(First embodiment)
FIG. 1 shows a functional block configuration of a transfer processing apparatus 1 as a first embodiment of the present invention.
In FIG. 1, the transfer processing device 1 includes an encoded data processing unit 11, a reception information processing unit 12, and a resource control unit 13. The transfer processing device 1 is connected to the transfer control device 4, the terminal 3a, and the terminal 3b so as to be able to communicate with each other.

  The transfer processing device 1 receives information including encoded data transmitted from the transmission source terminal 3a via the network of the communication carrier A, performs transfer processing on the received information, and performs the transfer processing of the communication carrier B. This is a device for transferring to a destination terminal 3b via a network. An example of information including encoded data includes, but is not limited to, an RTP (Real-time Transport Protocol) packet. Hereinafter, the received information is also referred to as received information.

  In the present embodiment, the transfer processing device 1 is described as transferring information transmitted from the terminal 3a to the terminal 3b. However, the direction in which the information transferred by the transfer processing device 1 flows is not limited. . All the following explanations are similarly explained by replacing terminal 3a and carrier A with terminal 3b and carrier B, and replacing terminal 3b and carrier B with terminal 3a and carrier A. The

  The transfer process includes a transmission / reception process and a digital process. In the transmission / reception process, the encoded data is extracted from the received information, the jitter buffer absorbs fluctuations and delays, and then the encoded data that has been digitally processed as necessary is assembled as transmission information and transmitted to the transmission destination. It is. The digital processing is processing for decoding encoded data extracted from received information in accordance with a transmission source codec and encoding in accordance with a transmission destination codec.

  The transfer control device 4 is a device that establishes a session between the terminal 3a and the terminal 3b and instructs the transfer processing device 1 to perform transfer processing on encoded data transmitted from the terminal 3a to the terminal 3b.

  Here, an example of the hardware configuration of the transfer processing apparatus 1 is shown in FIG. In FIG. 2, the transfer processing device 1 is configured by a computer device including a CPU (Central Processing Unit) 1001, a memory 1002, a network interface 1003, a processor group 1004 including a plurality of processors, and a memory 1005. The processor group 1004 includes processors # 1 to #n. However, hereinafter, when any one of the processors # 1 to #n is indicated, the same reference numeral as that of the processor group is used and described as “processor 1004”. The memory 1002 includes a RAM (Random Access Memory), a ROM (Read Only Memory), an auxiliary storage device (such as a hard disk), and the like. The network interface 1003 is an interface connected to the network. The processor group 1004 is provided to execute processing on the encoded data under the control of the CPU 1001 and includes, for example, a plurality of digital signal processors. The memory 1005 is configured by a RAM or the like used by the processor group 1004.

  In this case, the encoded data processing unit 11 is configured by a processor group 1004 that reads and processes computer programs and data stored in the memory 1005. The reception information processing unit 12 and the resource control unit 13 include a network interface 1003 and a CPU 1001 that reads a computer program and data stored in the memory 1002 and performs processing to control each unit. The hardware configuration of the transfer processing device 1 and each functional block thereof is not limited to the above-described configuration.

  Next, details of each functional block of the transfer processing apparatus 1 will be described.

  The encoded data processing unit 11 uses the resources allocated to the processor group 1004 to execute a transfer process for received information including encoded data.

  Here, as described above, in a general transfer processing device, resources (memory, etc.) that can be used by a processor such as a DSP (digital signal processor) are fixed for each use of the transmission / reception processing function and the digital processing function. Mapped to On the other hand, the encoded data processing unit 11 according to the present embodiment is realized on the processor group 1004 using a virtual technique. The transmission / reception processing resources and digital processing resources used by the encoded data processing unit 11 are adjusted in the allocation amount by the resource control unit 13 described later. In this embodiment, the resource is a processor and memory 1005 of the processor group 1004.

  That is, the encoded data processing unit 11 executes the transmission / reception process among the transfer process contents determined for the reception information using the transmission / reception processing resource. Specifically, the encoded data processing unit 11 executes the transmission / reception process by the processor 1004 assigned to execute the transmission / reception process using the memory 1005 assigned for the transmission / reception process. Also, if there is a digital process among the transfer process contents determined for the received information, the encoded data processing unit 11 executes the process using the digital processing resource. Specifically, the encoded data processing unit 11 performs digital processing by the processor 1004 assigned to perform digital processing using the memory 1005 assigned for digital processing. Hereinafter, “the processor 1004 allocated to execute the processing using the memory 1005 allocated for transmission / reception processing or digital processing” is referred to as “the processor to which resources for transmission / reception processing or digital processing are allocated”. 1004 ". Each processor 1004 can execute transmission / reception processing for one or more pieces of received information in parallel when transmission / reception processing resources are allocated. Further, each processor 1004 can execute digital processing on one or more pieces of received information in parallel when resources for digital processing are allocated.

  The reception information processing unit 12 receives information including encoded data transmitted from the terminal 3a. Then, the reception information processing unit 12 determines the transfer processing content based on the encoding scheme of the transmission source of the reception information and the encoding scheme of the transmission destination. Then, the reception information processing unit 12 causes the encoded data processing unit 11 to execute the determined transfer processing content.

  The reception information processing unit 12 may acquire information representing the transmission source encoding method and the transmission destination encoding method from the transfer control device 4. Alternatively, the reception information processing unit 12 may store the encoding method in association with information specifying the transmission source and the transmission destination. In this case, the reception information processing unit 12 analyzes the received information to acquire information for specifying the transmission source and the transmission destination, and acquires the encoding method stored corresponding to the acquired information. May be.

  Specifically, the reception information processing unit 12 is configured to encode the encoded data from the terminal 3a (the codec of the communication carrier A) and the encoding method of the encoded data that can be received by the terminal 3b (the communication carrier). The content of the transfer process is determined according to the combination with the codec (B). If the codec on the terminal 3a side and the codec on the terminal 3b side are the same, the reception information processing unit 12 determines the transfer processing content that codec conversion (digital processing) is not necessary when performing transmission / reception processing. Also good. If the codec on the terminal 3a side and the codec on the terminal 3b side are not the same, the reception information processing unit 12 determines the transfer processing content that codec conversion (digital processing) is necessary when performing transmission / reception processing. Also good.

  The resource control unit 13 adjusts the amount of each of the resources allocated for transmission / reception processing and digital processing based on the usage status of the resources related to transmission / reception processing and digital processing. Specifically, the resource control unit 13 adjusts the number of processors 1004 and the size of the memory 1005 allocated for transmission / reception processing and digital processing, respectively. For example, when it can be determined that the amount of resources used for transmission / reception processing tends to increase (or decrease), the resource control unit 13 expands (or reduces) the allocation of resources to the usage of transmission / reception processing. Also, for example, when it can be determined that the amount of resources used for digital processing tends to increase (or decrease), the resource control unit 13 expands (or reduces) the allocation of resources to digital processing applications. To do. In the initial stage, the resource control unit 13 allocates some of the resources for transmission / reception processing and allocates other portions for digital processing. At this time, the resource control unit 13 does not have to allocate all of the resources to any application.

  The operation of the transfer processing apparatus 1 configured as described above will be described with reference to FIG.

  First, the reception information processing unit 12 receives information including encoded data addressed to the terminal 3b from the terminal 3a (step S1).

  Next, the reception information processing unit 12 determines the transfer processing content according to the encoding scheme of the transmission source of the reception information and the encoding scheme of the transmission destination (step S2).

  Next, the reception information processing unit 12 causes the encoded data processing unit 11 to execute the transfer processing content determined in step S2 (step S3).

  Specifically, the encoded data processing unit 11 extracts encoded data from the reception information, and executes a reception process that absorbs delay and fluctuation by a jitter buffer using resources for transmission / reception processing. When the transfer processing content includes digital processing, the encoded data processing unit 11 performs codec conversion (digital processing) on the extracted encoded data using digital processing resources. Then, the encoded data processing unit 11 assembles encoded data subjected to codec conversion as necessary as transmission information, and executes transmission processing to transmit to the terminal 3b using resources for transmission / reception processing.

  Next, the resource control unit 13 adjusts the resource amount allocated to the transmission / reception process and the resource amount allocated to the digital process according to the resource usage status for each of the transmission / reception process and the digital process (step S4).

  As described above, for example, if the resource control unit 13 can determine that the amount of resources for transmission / reception processing tends to increase (or decrease), the resource control unit 13 expands (or reduces) the allocation of resources for transmission / reception processing. Further, for example, when it is possible to determine that the amount of resources for digital processing tends to increase (or decrease), the resource control unit 13 expands (or reduces) the allocation of resources for digital processing.

  Thus, the transfer processing device 1 ends the operation. In FIG. 3, it has been described that the operation is performed in the order of steps S1 to S4. However, the resource control operation in step S4 is not necessarily performed following step S3. The transfer processing device 1 may execute step S4 at every arbitrary timing.

  Next, effects of the first exemplary embodiment of the present invention will be described.

  The transfer processing device according to the first embodiment of the present invention is a transfer processing device that relays communication of encoded data between communication carriers, and uses resources while reducing the work cost related to performance enhancement. Efficiency can be further improved.

  The reason will be described. In the present embodiment, the reception information processing unit determines the transfer processing content according to the encoding method of the transmission source and transmission destination of the reception information including the encoded data, and the determined transfer processing is performed on the processor group. The encoded data processing unit that operates using the allocated resources is executed. This is because the resource control unit adjusts the amounts to be allocated as the transmission / reception processing resource and the digital processing resource based on the usage status of the resources related to the transmission / reception processing and the digital processing in the transfer processing.

  Thereby, this Embodiment can perform resource mapping more efficiently in the transfer processing apparatus which relays the information containing the coding data transmitted / received between communication carriers. Further, according to the present embodiment, it is possible to effectively use resources by suppressing waste of deployed resources. Furthermore, in this embodiment, it is not necessary to add hardware or perform registration work to increase resources, and it is possible to reduce capital investment and work costs.

  As described above, the present embodiment realizes an encoded data processing unit using a virtual technology on a plurality of processors mounted on a transfer processing device, so that the transmission / reception processing function and the digital processing function are used. Thus, resource allocation can be autonomously performed.

(Second Embodiment)
Next, a second embodiment of the present invention will be described in detail with reference to the drawings. Note that, in each drawing referred to in the description of the present embodiment, the same reference numerals are given to the same configuration and steps that operate in the same manner as in the first embodiment of the present invention, and the detailed description in the present embodiment. Description is omitted.

  First, FIG. 4 shows the configuration of a transfer processing device 2 as a second embodiment of the present invention. In FIG. 4, the transfer processing device 2 is replaced with the reception information processing unit 22 and the resource control unit 13 in place of the reception information processing unit 12 with respect to the transfer processing device 1 as the first embodiment of the present invention. And the resource control unit 23 is different. The transfer processing device 2 further includes a processing content holding unit 24 and a resource usage status holding unit 25.

  The processing content holding unit 24 stores a processing content table representing transfer processing content for a combination of a transmission source and a transmission destination. For example, the processing content table indicates whether or not codec conversion (digital processing) is necessary for a combination of information that can identify the communication carrier of the transmission source terminal and information that can identify the communication carrier of the transmission destination terminal. It may represent.

  An example of the processing content table is shown in FIG. In the example of FIG. 5, the processing content table includes a transmission source IP (Internet Protocol) address, a transmission destination IP address, a transmission source codec, a transmission destination codec, transmission / reception processing necessity, and digital processing necessity. It consists of information representing each. In FIG. 5, a transmission source IP address and a transmission destination IP address are examples of information for specifying a transmission carrier and a transmission destination communication carrier, respectively. For example, the transmission source IP address and the transmission destination IP address may represent a range of IP addresses assigned to the use terminal by the communication carrier.

  For example, the processing content holding unit 24 may store information predetermined as a data transfer policy in connection between communication carriers as such a processing content table. Further, for example, the processing content holding unit 24 may add, update, or delete such a processing content table based on information notified from the transfer control device 4. For example, in the example of FIG. 5, the ITU-T G. In the case of H.711, the transfer processing content that transmission / reception processing is necessary and digital processing is unnecessary is determined. Even when the transmission source codec and the transmission destination codec are the same, the ITU-T G. In the case of other than 711 (for example, between AMR-NBs (narrowbands) or between EVRCs), a transfer process content that transmission / reception processing and digital processing are required is defined. Further, when the transmission source codec and the transmission destination codec are different from each other, a transfer processing content that transmission / reception processing and digital processing are required is defined.

  The reception information processing unit 22 analyzes the reception information and acquires information indicating the transmission source and the transmission destination. Then, the reception information processing unit 22 refers to the transfer processing content table to determine the transfer processing content determined for the combination of the transmission source and the transmission destination of the reception information. Then, the reception information processing unit 22 causes the encoded data processing unit 11 to execute the determined transfer processing content.

  Note that the reception information processing unit 22 may discard the reception information as an illegal request when the information regarding the combination of the transmission source and the transmission destination of the reception information is not defined in the processing content table.

  The resource usage status holding unit 25 holds a resource usage status table representing the resource usage status. For example, the resource usage status table may hold information (resource transmission / reception processing or digital processing) currently assigned to each processor 1004 and information related to the processing amount. An example of the resource usage status table is shown in FIG. In the example of FIG. 6, the resource usage status table includes information representing processor identification information, allocated resources, and the number of communication channels in use. Here, the number of communication channels in use corresponds to the number of received information being processed by the processor, and is information related to the processing amount. For example, in the first line of FIG. 6, a resource for transmission / reception processing is assigned to the processor 1004 having the identification number 1, and this processor 1004 performs transmission / reception processing for each received information using 190 communication channels. It shows that you are doing. That is, it can be said that the resource usage status table represents the status (traffic trend) of the communication service by the transfer processing device 2.

  Further, the resource usage status holding unit 25 may hold a history of such a resource usage status table. In this case, the resource usage status holding unit 25 may store the time when the contents of the resource usage status table are updated and the updated resource usage status table in association with each other. In this case, the resource usage status holding unit 25 may discard a past resource usage status table after a predetermined period has elapsed.

  The reception information processing unit 22 updates the resource usage status table according to the transfer processing content by the encoded data processing unit 11. For example, the reception information processing unit 22 may cause the encoded data processing unit 11 to execute the transfer process, and then update the resource usage status table according to the content of the transfer process that has been executed. In addition, the reception information processing unit 22 may update the resource usage status table every time there is a change in the resources allocated to the processor 1004 that configures the encoded data processing unit 11.

  Based on the resource usage status table, the resource control unit 23 predicts future usage status of resources used for transmission / reception processing and digital processing, respectively. Then, the resource control unit 23 expands the amount of resources to be allocated for processing for which a future shortage of resources is predicted based on the predicted future resource usage status. Further, the resource control unit 23 reduces the amount of resources to be allocated for processing in which it is predicted that resources will remain in the future, based on the predicted resource usage status. For example, the resource control unit 23 may predict the future increase / decrease in resource usage and the increase / decrease in the transmission / reception processing and digital processing. If the resource usage status holding unit 25 holds a history of resource usage status, the resource control unit 23 performs transmission / reception processing and digital processing based on the statistical information of the resource usage status in a predetermined period until now. What is necessary is just to predict the future resource usage. In addition, a well-known technique is employable for a prediction process.

  Here, in the initial stage, the resource control unit 23 does not have to allocate all of the resources to the use of each process. The resource control unit 23 allocates a predetermined amount to each process. That is, in the initial stage, there may be a resource that is not assigned to any processing use. Then, when the resource control unit 23 increases the resource amount of the process whose increase is predicted, if there is a resource that is not allocated to any of the processing uses, an amount corresponding to the predicted increase amount Resources may be allocated. Further, the resource control unit 23 may reduce the amount of processing resources for which increase is not predicted and increase the amount of processing resources for which increase is predicted.

  For example, the resource control unit 23 detects that a large number of communications that do not require codec conversion occupy the service state of the transfer processing device 2 based on the resource usage status table. In this case, the resource control unit 23 predicts that the amount of resources necessary for digital processing will be smaller than the current amount. Based on the prediction result, the resource control unit 23 reduces the amount of resources allocated to the digital processing.

  Further, for example, the resource control unit 23 detects an increase in communication that does not require codec conversion. In this case, the resource control unit 23 predicts that the resource amount necessary for the transmission / reception process exceeds the current state. Based on the prediction result, the resource control unit 23 increases the amount of resources allocated to the transmission / reception process.

  Further, for example, the resource control unit 23 detects an increase in communication that requires codec conversion. In this case, the resource control unit 23 predicts that the resource amount necessary for digital processing exceeds the current state. Based on this prediction result, the resource control unit 23 expands the amount of resources allocated to digital processing.

  The resource control unit 23 autonomously adjusts the resource allocation amount as described above without receiving an instruction from the transfer control device 4.

  Note that the resource control unit 23 may adjust the resource amount at the timing when the resource usage status table is updated. Alternatively, the resource control unit 23 may adjust the resource amount at predetermined timings asynchronously with the update process of the resource usage status table.

  The operation of the transfer processing device 2 configured as described above will be described with reference to the drawings.

  First, the transfer processing operation of the transfer processing device 2 is shown in FIG.

  In FIG. 7, first, the reception information processing unit 22 receives information including encoded data addressed to the terminal 3b from the terminal 3a (step S1).

  Next, the reception information processing unit 22 analyzes the reception information, acquires information indicating the transmission source and the transmission destination, and determines the transfer processing content defined in the processing content table for the combination of the transmission source and the transmission destination. (Step S22).

  Next, the reception information processing unit 22 causes the encoded data processing unit 11 to execute the transfer processing content determined in step S22 (step S3).

  Next, the reception information processing unit 22 updates the resource usage status table (step S24).

  Thus, the transfer processing device 2 ends the transfer processing operation.

  Next, the resource control operation of the transfer processing device 2 is shown in FIG.

  In FIG. 8, first, the resource control unit 23 predicts a future resource usage status in the transmission / reception process and the digital processing based on the resource usage status table (step S31).

  Next, the resource control unit 23 determines whether it is necessary to adjust (enlarge or reduce) the resource amount allocated to the transmission / reception process and the digital process, based on the resource usage situation predicted in step S31. (Step S32).

  Here, when it is not necessary to adjust the resource amount, the transfer processing device 2 ends the resource control operation.

  On the other hand, when it is determined that the resource amount of the transmission / reception process needs to be adjusted (Yes in step S32, “transmission / reception process” in step S33), the resource control unit 23 adjusts the resource amount allocated to the use of the transmission / reception process (step S32). S34).

  On the other hand, if it is determined that adjustment of the amount of resources for digital processing is necessary (Yes in step S32, “digital processing” in step S33), the resource control unit 23 adjusts the amount of resources allocated to the use of digital processing (step S32). S35).

  Thus, the transfer processing device 2 ends the resource control operation. The transfer processing device 2 may repeat such a resource control operation at every predetermined timing.

  Next, the effect of the second exemplary embodiment of the present invention will be described.

  The transfer processing apparatus according to the second embodiment of the present invention is a transfer processing apparatus that relays communication of encoded data between communication carriers, while using resources while reducing work costs related to performance enhancement. Efficiency can be further improved.

  The reason is that, in addition to the configuration similar to the first embodiment of the present invention, the reception information processing unit is determined for the combination of the transmission source and the transmission destination of the reception information based on the processing content table. This is because the transfer processing content is determined. As a result, in the present embodiment, for the transmission source and the transmission destination of the combination defined in the processing content table, the transfer control content autonomously is notified without being notified of the codec to be adopted by the transfer control device. Can be determined.

  In addition, the reception information processing unit updates the resource usage status table according to the content of the transfer processing by the encoded data processing unit. Then, the resource control unit predicts a future resource use state based on the resource use state table, and predicts a transmission / reception process or a digital process that requires resource adjustment (expansion or reduction). This is because the resource control unit adjusts (enlarges or reduces) the allocation of the resource amount for the processing that is determined to require resource adjustment.

  As described above, the present embodiment expands the resource amount for a process in which an increase in the processing amount is predicted in the transmission / reception process and the digital process, and the resource is predicted to be insufficient with the current allocation amount. Further, according to the present embodiment, a reduction in the processing amount is predicted among the transmission / reception processing and the digital processing, and the resource amount is reduced with respect to the processing in which the resource is predicted to remain with the current allocation amount. As a result, in the present embodiment, it is possible to effectively use the entire resource including a plurality of processor groups and memories, as compared with the case where the fixedly allocated resources are used for transmission / reception processing and digital processing in each processor. it can.
