An example of hardware constitutions of information processor 200 is shown roughly.

  Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention.

  FIG. 1 schematically shows an example of a communication environment of the communication system 10. FIG. 1 shows an example in which the communication system 10 according to the present embodiment is applied to a W-CDMA mobile communication network. The communication system 10 includes a relay apparatus 100, an information processing apparatus 200, an MSC (Mobile Switching Center) 300, an RNC (Radio Network Controller) 400, and a BTS (Base Transceiver Station) 500.

  The relay device 100 relays communication between the BTS 500 and the MSC 300. The relay apparatus 100 communicates with the BTS 500 via the RNC 400 that controls the BTS 500. The MSC 300 may be an example of a switching center. The BTS 500 may be an example of a radio base station. Although FIG. 1 schematically illustrates an example in which the relay device 100 is connected to two RNCs 400, the relay device 100 may be connected to three or more RNCs 400. Further, the number of BTSs 500 and communication terminals 600 is not limited to the number shown in FIG.

  The information processing apparatus 200 receives and processes a RANAP (Radio Access Network Application Part) signal transmitted and received between the MSC 300 and the RNC 400 via the relay apparatus 100 from the relay apparatus 100. The RANAP signal may be an example of communication data communicated via the relay device 100. Although FIG. 1 schematically illustrates an example in which the information processing device 200 is connected to one relay device 100, the information processing device 200 may be connected to two or more relay devices 100.

  When relaying the RANAP signal transmitted from the RNC 400 to the MSC 300, the relay apparatus 100 transmits the RANAP signal to the MSC 300 and the information processing apparatus 200. Further, when relaying the RANAP signal transmitted from the MSC 300 to the RNC 400, the relay device 100 transmits the RANAP signal to the RNC 400 and the information processing device 200.

  The information processing apparatus 200 may generate quality information related to the quality of communication provided to the communication terminal 600 by the BTS 500 based on the Disconnect signal, the Cause value, and the base station identification information included in the RANAP signal. The Disconnect signal is a signal indicating that the call by the communication terminal 600 has ended. The Disconnect signal may be an example of disconnection information indicating that communication by the communication terminal 600 wirelessly connected to the BTS 500 has been completed.

  The Cause value is a value indicating the reason why a specific event occurs in the RANAP protocol. The Cause value includes a value indicating the reason why communication by the communication terminal 600 is terminated. For example, “Release Due To UE Generated Signaling Connection Release”, which is one of the Cause values, indicates that the communication is normally terminated by the termination instruction from the communication terminal 600. Also, “Radio Connection With UE Lost”, which is one of the Cause values, indicates that communication has been terminated due to disconnection of the radio link. The Cause value may be an example of cause information indicating a cause of termination of communication by the communication terminal 600 wirelessly connected to the BTS 500.

  The base station identification information is information for identifying a base station related to the RANAP signal. For example, the base station identification information in the RANAP signal including the Disconnect signal is identification information for identifying the BTS 500 to which the communication terminal 600 to which the call has ended belongs. The base station identification information may be LAC (Location Area Code). Further, the base station identification information may be SAC (Service Area Code).

  When the information processing apparatus 200 receives a RANAP signal including a Disconnect signal, the information processing apparatus 200 may determine which communication terminal 600 belonging to which BTS 500 has ended by referring to the base station identification information. Further, the information processing apparatus 200 may determine the cause of the end of communication by referring to the Cause value.

  The information processing apparatus 200 may count the number of times of a plurality of types of Cause values for each BTS 500. Then, the information processing apparatus 200 may generate quality information regarding the quality of communication provided to the communication terminal 600 by the BTS 500 based on the number of Cause values for each BTS 500. For example, the information processing apparatus 200 may calculate, as the quality information, the ratio of the number of times communication is normally terminated by the termination instruction from the communication terminal 600 out of the number of communications terminated within a predetermined time. Further, the information processing apparatus 200 may calculate, as the quality information, the ratio of the number of times communication is terminated due to the disconnection of the wireless link among the number of communications terminated within a predetermined time.

  The information processing apparatus 200 may present the quality of communication provided to the communication terminal 600 by each BTS 500 by presenting the generated quality information to the operator. For example, the information processing apparatus 200 uses the BTS 500 to communicate with the communication terminal when the ratio of the communication end number due to the disconnection of the radio link exceeds a predetermined threshold among the number of communication ends within a predetermined time. The operator is informed that the quality of the communication provided to 600 has deteriorated. Thereby, the operator can grasp that communication by the BTS 500 is unstable.

  The information processing apparatus 200 may update the quality information and present it to the operator each time a RANAP signal is received. Thereby, the operator can grasp | ascertain the quality information by each BTS500 in real time.

  FIG. 2 schematically shows a functional configuration of the information processing apparatus 200. The information processing apparatus 200 includes a reception unit 202, a storage unit 204, a quality information generation unit 206, a display control unit 208, a display unit 210, an input unit 212, a transmission unit 214, and a control unit 216.

  The receiving unit 202 receives a RANAP signal from the relay device 100. The storage unit 204 stores the RANAP signal received by the receiving unit 202. The quality information generation unit 206 generates quality information related to communication quality provided to the communication terminal 600 by the BTS 500 based on the plurality of RANAP signals stored in the storage unit 204.

  The quality information generation unit 206 may extract the base station identification information and the Cause value from the RANAP signal including the Disconnect signal, and count the number of times of each of a plurality of types of Cause values for each BTS 500. The quality information generation unit 206 may register the count result in the count table stored in the storage unit 204. In addition, the quality information generation unit 206 may update the count table every time a RANAP signal is received.

  The display control unit 208 maps an image representing the BTS 500 on the map image and causes the display unit 210 to display the image. The display control unit 208 may map an image representing the BTS 500 at a position on the map image corresponding to the place where the BTS 500 is actually installed. In addition, the display control unit 208 may map an image schematically representing the communication area of the BTS 500 on the map image and cause the display unit 210 to display the image.

  The display control unit 208 may display quality information indicating the communication quality of the BTS 500 in association with an image representing the BTS 500. For example, the display control unit 208 displays the number of times for each type of cause of communication disconnection in association with an image representing the BTS 500. The display control unit 208 may display the number of times by an image such as a graph. The display control unit 208 may change at least one of the color of the image representing the BTS 500 and the image representing the communication area of the BTS 500 in accordance with the high quality indicated by the quality information.

  The input unit 212 receives input from an operator, for example. The input unit 212 may accept a display content change instruction from the operator. Then, the display control unit 208 may change the content displayed on the display unit 210 in accordance with the change instruction received by the input unit 212. For example, the input unit 212 receives a setting instruction for the BTS 500 from the operator. The setting instruction may include at least one of a tilt angle change instruction, a radio wave intensity change instruction, and a reset instruction.

  The transmission unit 214 transmits the setting change instruction for the BTS 500 received by the input unit 212 to the RNC 400. The transmission unit 214 may transmit control data instructing a setting change for the BTS 500 to the RNC 400. This allows the RNC 400 to change the setting of the BTS 500. The transmission unit 214 may transmit instruction data for instructing the operator of the RNC 400 to change the setting for the BTS 500. Thereby, it is possible to instruct the operator of the RNC 400 to change the setting of the BTS 500.

  The control unit 216 controls the reception unit 202, the storage unit 204, the quality information generation unit 206, the display control unit 208, the display unit 210, the input unit 212, and the transmission unit 214.

  FIG. 3 shows an example of a plurality of types of Cause values. CauseNo. 14 "Failure in the Radio Interface Procedure" indicates that the call has ended due to a procedure error such as an error in the communication destination. CauseNo. 15 "Release Due To UTRAN Generated Reason" indicates that the call is terminated due to a cause occurring in the UTRAN section. For example, it indicates that the telephone call has been terminated due to equipment maintenance work or equipment failure in the UTRAN section.

  CauseNo. 40 "Release Due To Generated Signaling Connection Release" indicates that the call has been normally terminated by a termination instruction from the communication terminal. CauseNo. “Resource Optimization Relocation” 41 indicates that the call has been terminated due to resource reallocation. CauseNo. 46 "Radio Connection With UE Lost" indicates that the call is terminated due to the disconnection of the wireless connection.

  FIG. 4 shows an example of a counting table stored in the storage unit 204. The count table shown in FIG. The example which counted the number of times of 14, 15, 40, 41, 46 is shown. The number of times registered in the count table may include the number of other Cause values.

  The quality information generation unit 206 may generate quality information of the BTS 500 based on the counting table. For example, the quality information generation unit 206 determines the cause No. for the number of communications completed within a predetermined time. A ratio of 40 times may be calculated as quality information. As a result, the ratio of the number of times communication is normally terminated by the termination instruction from the communication terminal in the number of communications terminated within a predetermined time can be generated as quality information.

  In addition, the quality information generation unit 206 determines the cause No. for the number of communications completed within a predetermined time. The ratio of 46 times may be calculated as quality information. As a result, the ratio of the number of times communication is terminated due to the disconnection of the radio link in the number of communications terminated within a predetermined time can be generated as quality information.

  In addition, the quality information generation unit 206 determines the cause No. for the number of communications completed within a predetermined time. A ratio of 15 times may be calculated as quality information. As a result, the ratio of the number of times communication is completed due to equipment failure or equipment maintenance work in the number of communications finished within a predetermined time can be generated as quality information. Note that the count table may be registered with cumulative values since the start of counting, or may be generated every predetermined time.

  5 and 6 schematically show display examples by the display control unit 208. FIG. 5 and 6 show an example in which an image 222 representing the BTS 500 and an image 224 representing the communication area of the BTS 500 are displayed on the map image. The image representing the communication area may be an image representing a pre-registered area. The area registered in advance may be an area derived from a theoretical value. Moreover, it may be registered in advance by a provider who provides the information processing apparatus 200.

  The display control unit 208 may change the display mode of at least one of the image 222 and the image 224 for each BTS 500 in accordance with the quality level indicated by the generated quality information. For example, the display control unit 208 identifies and displays at least one of the image 222 and the image 224 depending on whether the high quality indicated by the quality information exceeds a predetermined threshold. In the example shown in FIGS. 5 and 6, identification display is performed by hatching the image 224 corresponding to the BTS 500 whose quality information is lower than a predetermined threshold. As a result, among the plurality of BTSs 500, the operator or the like can easily recognize the BTS 500 in which the quality of communication to be provided is degraded.

  In addition, although the example which identifies and displays by hatching was given and demonstrated here, it is not restricted to this. The identification display may be performed based on the difference in color, or the identification display may be performed based on the difference in shape. Further, the identification display may be performed in multiple stages instead of two stages. For example, the quality may be evaluated in five levels and may be identified and displayed in five levels.

  FIG. 6 shows an example in which the property information 226 of the BTS 500 is displayed. The property information 226 may include a service area identifier (SAI), the current number of communications, the status of the BTS 500, and a predicted state. In the example of FIG. 6, it is indicated that the status is unstable and the radio wave intensity may be weak. The information processing apparatus 200 is predicted when, for example, the ratio of the number of times communication is terminated due to disconnection of a wireless link exceeds a predetermined threshold among the number of communications completed within a predetermined time. The radio wave intensity may be weak.

  For example, when the input control unit 212 detects that the mouse cursor is placed on the image 222, the display control unit 208 displays the property information 226 corresponding to the BTS 500 on which the mouse cursor is placed. Further, the display control unit 208 may display the property information 226 corresponding to the BTS 500 displayed on the display unit 210 when a zoom-in operation is performed.

  Further, the display control unit 208 may display a setting menu (not shown) for giving a setting instruction to the BTS 500 at a position corresponding to the designated BTS 500. The setting menu may include a tilt angle change instruction, a radio wave intensity change instruction, and a reset instruction.

  FIG. 7 schematically shows a display example by the display control unit 208. The display control unit 208 may cause the display unit 210 to display only quality information of a predetermined BTS 500 among the plurality of BTSs 500. FIG. 7 shows an example in which only predetermined 15 BTS 500 quality information is displayed.

  The predetermined BTS 500 may be designated by the operator. For example, a plurality of candidate BTSs 500 may be displayed on the display unit 210 and selected by the operator. At this time, the display control unit 208 may display the BTSs 500 connected to the same RNC 400 as one group so that they can be selected for each group.

  FIG. 8 shows an example of a flowchart of processing by the information processing apparatus 200. The flowchart shown in FIG. 8 will be described with the state where the information processing apparatus 200 is turned on as a start state. In step S802, the reception unit 202 receives a RANAP signal from the relay device 100.

  In step S804, the control unit 216 determines whether or not the received RANAP signal includes a Disconnect signal. If the Disconnect signal is not included, the process returns to step S802. If a Disconnect signal is included, the process proceeds to step S806.

  In step S806, the quality information generation unit 206 updates the count table by counting up the number of times corresponding to the Cause value included in the RANAP signal. In step S808, the quality information of the BTS 500 corresponding to the base station identification information included in the RANAP signal is updated based on the updated count table.

  In step S810, the control unit 216 determines whether to change the display. For example, the control unit 216 determines to change the display when the quality information exceeds or falls below a predetermined threshold by updating the quality information. If it is determined not to change the display, the process returns to step S802. If it is determined to change the display, the process proceeds to step S812.

  In step S812, the display control unit 208 changes the display. For example, when the quality information is less than a predetermined threshold due to the update of the quality information in step S808, the colors of the image 222 and the image 224 corresponding to the BTS 500 indicated by the base station identification information are changed. In step S814, the control unit 216 determines whether an end instruction has been received. If it is determined that an end instruction has not been received, the process returns to step S802. If it is determined that an end instruction has been received, the process ends.

  Thus, by updating the quality information every time a RANAP signal is received and changing the display, the operator can grasp the quality information by each BTS 500 in real time. Note that the information processing apparatus 200 may execute the count of the cause value, the update of the quality information, and the presentation each time a predetermined number of RANAP signals are received instead of every time one RANAP signal is received. .

  According to the communication system 10 according to the present embodiment, real-time quality information update and presentation are executed by the information processing apparatus 200 instead of the MSC 300. Thereby, real-time quality information can be updated and presented without increasing the processing load of the MSC 300.

  FIG. 9 shows an exemplary hardware configuration of the information processing apparatus 200. The information processing apparatus 200 includes a host controller 902, a CPU 904, a RAM 906, an input / output controller 908, a ROM 910, and a communication interface 912.

  The host controller 902 connects the RAM 906 and the CPU 904 that accesses the RAM 906. The CPU 904 operates based on programs stored in the ROM 910 and the RAM 906 to control each unit. The input / output controller 908 connects the host controller 902, the ROM 910, and the communication interface 912.

  A program installed and executed in the information processing apparatus 200 works on the CPU 904 and the like, and the information processing apparatus 200 is described with reference to FIGS. 1 to 8. The receiving unit 202, the storage unit 204, the quality information generation unit 206, and the display It functions as a control unit 208, a display unit 210, an input unit 212, a transmission unit 214, and a control unit 216.

  Each unit included in the relay device 100 according to the present embodiment may be configured by installing a program for performing various processes and causing the computer to execute the program. That is, by causing a computer to execute a program that performs a process of relaying communication between the BTS 500 and the MSC 300 and a process of transmitting communication data to the information processing apparatus 200, the computer functions as each unit included in the relay apparatus 100. Thus, the relay device 100 may be configured.

  In the present embodiment, when an RANAP signal is received from the MSC 300 or the RNC 400, an example in which the RANAP signal is transmitted to the information processing device 200 has been described. However, the relay device 100 transmits the RANAP signal to the information processing device 200. May be filtered. For example, the relay apparatus 100 transmits the RANAP signal to the information processing apparatus 200 only when the Disconnect signal is included in the RANAP signal received from the MSC 300 or the RNC 400. Thereby, the processing load of the information processing apparatus 200 can be reduced.

  In the present embodiment, the display control unit 208 has been described with an example in which the quality information is displayed on the display unit 210 included in the information processing apparatus 200. However, the present invention is not limited to this. The display control unit 208 may display the quality information on a display unit included in another device.

  In the present embodiment, the example in which the reception unit 202 receives the RANAP signal has been described. However, the reception unit 202 further includes information indicating the signal strength of a signal transmitted and received between the BTS 500 and the communication terminal 600. You may receive it. Then, the quality information generation unit 206 may generate quality information based on the Disconnect signal, the Cause value, and the signal strength.

  For example, when the Cause value is “Release Due To UE Generated Signaling Connection Release”, the quality information generation unit 206 separately counts when the signal strength is higher or lower than the predetermined strength. Good. As a result, it is possible to distinguish between a case where the call is normally terminated and a case where the call is unavoidably terminated due to a decrease in the call quality.

  In addition, the reception unit 202 may further receive communication source identification information indicating the communication source communication terminal 600 and communication destination identification information indicating the communication destination communication terminal 600 for each communication. Then, the quality information generation unit 206 may generate the quality information based on the number of times communication with the same communication source and communication destination has started before a predetermined time has elapsed after the end of communication. For example, when the Cause value is “Release Due To UE Generated Signaling Connection Release” and the signal strength is lower than the predetermined strength, the quality information generation unit 206 has a predetermined time after the end of communication. Before the time elapses, the number of times communication with the same communication source and communication destination has started may be counted. Thereby, when communication is terminated by a termination instruction from the communication terminal, it is possible to improve the accuracy with which it is unavoidable that the call has been terminated due to a decrease in call quality.

  In the above-described embodiment, an example in which the communication system 10 is applied to a W-CDMA mobile communication network has been described. However, the present invention is not limited to this and may be applied to other mobile communication networks. For example, the communication system 10 may be applied to an LTE (Long Term Evolution) mobile communication network. In particular, the communication system 10 may be applied to VoLTE (Voice over LTE).

  When the communication system 10 is applied to an LTE mobile communication network, the relay device 100 may relay communication between an ENodeB and an MME (Mobility Management Entity). Further, the information processing apparatus 200 may receive and process communication data transmitted and received between the Node B and the MME via the relay apparatus 100 from the relay apparatus 100. The communication data may be an S1AP (S1 Application Protocol) signal. The ENodeB may be an example of a radio base station. The MME may be an example of an exchange.

  When changing the setting of the Node B, a setting change instruction may be transmitted from the information processing apparatus 200 to the Node B. For example, the information processing apparatus 200 may log in to the Node B via Telnet and transmit a setting change instruction to the Node B.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above embodiment. It is apparent from the description of the scope of claims that embodiments with such changes or improvements can be included in the technical scope of the present invention.
