Abstract

PROBLEM TO BE SOLVED: To provide a call processing server capable of suppressing convergence resultant from positioning start request not relying upon third person retrieval.SOLUTION: When a MO receiving section 106 receives a MO call, i.e., a positioning start request, from a portable terminal 200, a regulation control section 102 performs regulation control based on the identification information (e.g., IMSI) of the portable terminal 200, and the searched person information (e.g., IMSI) of the search object of a positioning request (transmission of MT call) by third person retrieval. Consequently, positioning start request not corresponding to third person retrieval can be rejected. A determination can be made that a positioning start request not corresponding to third person retrieval is not relatively important processing. Consequently, convergence can be reduced in call processing server.SELECTED DRAWING: Figure 2

JP 2001-69565 A

  By the way, by using a mobile communication network, a positioning request from a third party is transmitted to an arbitrary portable terminal, and a positioning start request by SUPL positioning is received from the portable terminal, whereby a positioning request from a third party is received. In general, a service for acquiring position information of an arbitrary mobile terminal is known.

  When such a service is to be used when the mobile communication network or the server is in a congested state, the position determination request by the third party search is a degree of urgency by the method described in Patent Document 1. Can be regulated by. On the other hand, a positioning start request, which is a response to a positioning request based on a third party search with high urgency, is subject to regulation in a congested state because the transmission source is not registered. Therefore, there may be a case where position measurement by a highly urgent third party search is not performed.

Therefore, in order to solve the above-described problems, an object of the present invention is to provide a call processing server that can make a positioning start request by a third party search even in a congested state.
The purpose is to provide.

  In order to solve the above-described problem, the call processing server of the present invention stores a search target person information that is a search target of a positioning request by a third party search in a call processing server that communicates with a terminal. And when the call processing server is in a congested state, when receiving a positioning start request from the mobile terminal, the positioning is based on the identification information of the mobile terminal and the search target person information stored in the storage unit. A restriction control unit that performs restriction control on the start request.

  According to the present invention, when a positioning start request is received from a mobile terminal, restriction control is performed based on the identification information of the mobile terminal and the search target person information stored at the time of a position positioning request by a third party search. Thereby, for example, the request for the positioning start according to the third party search is accepted, and the restriction control for restricting the other positioning start requests is made possible. Positioning start requests according to third-party search are important processes, so such requests should be processed with priority, and other requests will be subject to regulation. The positioning process can be performed reliably and congestion in the call processing server can be reduced.

  ADVANTAGE OF THE INVENTION According to this invention, even if a call processing server is a congestion state, the positioning start request | requirement by a third party search can be made possible.

  Embodiments of the present invention will be described with reference to the accompanying drawings. Where possible, the same parts are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 1 is a system configuration diagram of a communication system including a call processing server 100 according to the present embodiment. As shown in FIG. 1, a plurality of call processing servers 100 are arranged on the network. When a third party search request for positioning is sent from the CP (content provider) or the emergency call organization 210 in accordance with a request from the search requester, via the GW 220 and the LB (load balancer) 230, A third party search request is transmitted to one call processing server 100. Note that the GW 220 can identify the mobile terminal 200 as a destination by referring to the subscriber information stored in the subscriber information device 220a. Further, the LB 230 selects one call processing server 100 from among the plurality of call processing servers 100 so that the processing is distributed, and transmits a third party search request to the one call processing server 100. .

  The call processing server 100 determines whether or not to transmit a third party search request to the mobile terminal 200 to be searched according to the congestion state and the degree of urgency of the call processing server 100. In response to a request from the call processing server 100, the SMS storage / distribution server 240 transmits a control SMS indicating a third party search request to the mobile terminal 200, and the mobile terminal 200 transmits a third party based on the control SMS. Start positioning according to the search request. In the present embodiment, the mobile terminal 200 transmits a positioning start request to the call processing server 100 in order to perform positioning processing by SUPL. The LB 250 selects one call processing server 100 and transmits a positioning start request, similarly to the LB 230 described above. Instead of the SMS storage / distribution server 240, a push notification server for starting an application by WAP or the like may be used.

  When receiving the positioning start request, the call processing server 100 determines whether the positioning start request is to be regulated according to the congestion state of the call processing server 100 and the degree of urgency of the positioning start request. To do.

  Next, functions of the call processing server 100 will be described. FIG. 2 is a functional block diagram showing functions of the call processing server 100. As shown in FIG. 2, the call processing server 100 includes an MT receiving unit 101, a regulation control unit 102 (a regulation control unit, a congestion state judgment unit), a call management unit 103 (an identification information judgment unit, a broadcast processing unit, a deletion unit). ), An MT call table (TBL) 104 (storage unit), a timer 104a (timer unit), an MT control unit 105, an MO reception unit 106, and an MO control unit 107.

  The MT receiving unit 101 receives an MT-LR (Mobile Terminated Location Request: hereinafter referred to as an MT call), which is a search request by a third party for position measurement transmitted from the CP / emergency call organization 210. Part. The positioning process using this MT call is defined in 3GPPTS 23.271.

  When the call processing server 100 is in a congested state (for example, when the CPU usage rate exceeds the congestion threshold or the total amount of data is restricted, the restriction control unit 102 determines the number of signals to be processed at the same timing. If the MT call is received, an emergency call organization such as an emergency call organization is in an emergency state based on the source of the MT call. It is a part that determines whether or not the call originates from a sender having a characteristic and performs processing based on the determination. When the restriction control unit 102 receives an MT call from an urgent organization in a congested state, the restriction control unit 102 passes the MT call (emergency MT call) to the call management unit 103. Further, when an MT call (general MT call) from an organization with less urgency is received in a congested state, the MT call is discarded without being passed to the call management unit 103. Furthermore, when not in a congestion state, all MT calls (general MT calls and emergency MT calls) are passed to the call management unit 103.

  In addition, the restriction control unit 102 responds according to the type of MO-LR (Mobile Originated Location Request: hereinafter referred to as an MO call) indicating a positioning start request by SUPL transmitted from the mobile terminal 200 and the congestion state. The restriction process is performed. As will be described later, the type of the MO call is determined by the call management unit 103. In addition, as a restriction process, when a predetermined number of signals (the number of signals transmitted / received to / from the call processing server including the MT-MO call and the MO call) is equal to or greater than a predetermined value, a process that restricts further processing is performed. Yes, but not limited to that.

  The call management unit 103 determines that the restriction control unit 102 has received an emergency call MT call that is urgent in a congested state, or all MTs including an MT call that has no urgency when the congestion state is not present. When it is determined that a call (general MT call and emergency MT call) has been received, identification information (for example, IMSI, MSISDN) to be searched is determined whether the call is a general MT call or an emergency MT call. The indicated call type and the elapsed time since storage in the MT call table 104 are associated with each other and stored in the MT call table 104.

  FIG. 3 is a diagram illustrating a specific example of information stored in the MT call table 104. As shown in FIG. 3, the MT call table 104 stores the call type, IMSI, MSISDN, and elapsed time. The elapsed time is time information indicating how much time has elapsed since the call type was stored in accordance with the timer function of the timer 104a.

  Note that both IMSI and MSISDN are stored, but either one may be used to identify the mobile terminal. Moreover, what is necessary is just the information which identifies the portable terminal used not only for these but to be searched.

  Instead of the elapsed time, the time when the call type or the like is stored in the MT call table 104 or the time when the MT call is received by the MT receiving unit 101 may be stored in association with each other. The call management unit 103 may grasp the elapsed time by comparing this time with the current time, and delete the corresponding record in the MT call table 104 when a predetermined time has elapsed.

  In addition, in order to synchronize with the MT call table of another call processing server 100, the call management unit 103 receives the MT call by the MT receiving unit 101 and stores the information in the MT call table 104. The call processing server 100 is notified of the call type, IMSI, and MSISDN. The elapsed time is also managed in association with other call processing servers 100.

  Further, when an MO call is received by the MO receiving unit 106, the call management unit 103 refers to the MT call table 104, and the identification information of the mobile terminal 200 that is the source of the MO call is stored in the MT call table 104. It is determined whether or not it matches the stored search target. If they match, it is determined as an MO call corresponding to an emergency MT call or a general MT call. If they do not match, it is determined that the MO call does not correspond to the MT call, that is, the MO call alone.

  In the present embodiment, the MT call table 104 is provided in each call processing server 100 and is configured to be synchronized with each other, but is not limited thereto. The MT call table 104 may be described in one shared disk (corresponding to a database) arranged so as to be accessible to each call processing server 100. By being described in such a single shared disk, when the process for restricting the MT-MO call is completed, the timer process can be eliminated by deleting the corresponding record. Of course, record management may be performed by timer processing.

  The MT control unit 105 receives the MT call stored in the MT call table 104 in the call management unit 103 and transmits it to the SMS accumulation / distribution server 240. The SMS / distribution server 240 causes the positioning process to be performed by transmitting a control SMS indicating an MT call to the mobile terminal 200 to be searched.

  The MO receiving unit 106 is a part that receives an MO call indicating a positioning start request by SUPL transmitted from the mobile terminal 200. The positioning process using the MO call is defined in 3GPPTS 23.271.

  The MO control unit 107 transmits the MO call to the GW 220 when the restriction control unit 102 does not restrict the MO call. The transmitted MO call is subjected to processing for SUPL positioning, and assist data for GPS positioning of the mobile terminal 200 is provided to the mobile terminal 200.

  Next, the operation of the call processing server 100 will be described. 4 and 5 are flowcharts showing the operation of the call processing server 100. FIG. FIG. 4 is a processing flow when received by the MT receiving unit 101 in the call processing server 100.

  When the MT call is received by the MT receiver 101 (S101), the restriction controller 102 determines whether the call is an emergency call or a general call based on the caller (S102). Then, the restriction control unit 102 determines whether the CPU is in a congestion state based on, for example, whether the usage rate of the CPU exceeds a congestion threshold (S103). If it is determined that the number is exceeded, it is determined that the restriction is in effect, the MT call that is a general call is discarded, and the MT call that is an emergency call is passed to the call management unit 103 without being discarded. (S104). If it is determined that the number does not exceed, all MT calls are transferred to the call management unit 103 without distinguishing between general calls and emergency calls.

  Depending on the congestion state, the call management unit 103 stores only the emergency MT call or the general MT call and the emergency MT call in the MT call table 104 in association with the identification information and the elapsed time of the search target. (S105). The call management unit 103 notifies the other call processing server 100 of call type information, identification information to be searched, and elapsed time, and synchronizes the MT call table 104 (S106).

  Then, the MT call is transmitted to the mobile terminal 200 that is the search target (S107). In portable terminal 200, when an MT call is received, processing for starting positioning (transmission of an MO call) is performed.

  FIG. 5 is a flowchart showing processing of the call processing server 100 when an MO call for starting positioning is received from the mobile terminal 200. When the MO reception unit 106 receives an MO call indicating a positioning start request by SUPL from the mobile terminal 200 (S201), the call management unit 103 reads the MT call table 104. Then, the call management unit 103 determines whether or not the identification information of the mobile terminal 200 that is the source of the MO call is stored in the MT call table 104, and based on this, the call type of the MO call is determined ( S203).

  Here, when stored in the MT call table 104, it is an MO call corresponding to an emergency MT call (emergency MT-MO call) or an MO call corresponding to a general MT (general MT-MO call). To be judged. If it is not stored, it is determined that the MO call does not correspond to the MT call, that is, the positioning start by the user of the mobile terminal 200 itself. In this specification, such an MO call is referred to as an MO call alone.

  Then, the restriction control unit 102 determines the degree of congestion of the call processing server 100 (CPU usage rate, etc.) (S204, S205). The restriction control unit 102 executes temporary restriction, two-time restriction, or no restriction according to the state of congestion. When the restriction control unit 102 determines that the congestion state exceeds the primary threshold and also exceeds the secondary threshold (secondary threshold> primary threshold), the MO call alone and the general MT-MO call are Discarded (S206). The emergency MT-MO call is delivered to the MO control unit 107 without being discarded, and processing for positioning by SUPL is performed (S208). The primary threshold value and the secondary threshold value described above are different from the threshold values shown in S103 of FIG. Since the number of calls and the processing load are different between the MT call and the MO call, it is necessary to manage the congestion state separately.

  If the restriction control unit 102 determines that the congestion state exceeds the primary threshold but does not exceed the secondary threshold, only the MO call alone is discarded (S207), and the general MT-MO call The emergency MT-MO call is passed to the MO control unit 107 without being discarded. Then, processing for positioning by SUPL is performed (S208).

  In addition, when the restriction control unit 102 determines that the congestion state does not exceed the primary threshold, it is not restricted, and therefore, all the MO calls are not discarded and the positioning by SUPL is performed. Is performed (S208). Note that the processing of S204 to S206 may be omitted. Regardless of the degree of urgency, only a single MO call may be discarded during congestion.

  In this flowchart, the processing for positioning by SUPL is to send a start instruction for SUPL positioning.

  Although the present embodiment is described on the assumption that an MO call is received, the position information itself measured by the GPS in the mobile terminal 200 may be received.

  Next, timer management of the MT call table 104 will be described. FIG. 6 is a flowchart showing timer management processing performed by the call management unit 103. When the call management unit 103 stores the call type, IMSI, and MSISDN in the MT call table 104, the timer 104a performs counting (S301). When the call management unit 103 determines that the timer 104a in each record has timed (S302), the corresponding record is deleted from the MT call table 104. (S303). In this way, information regarding old MT calls does not remain in the MT call table 104, and memory efficiency can be improved.

  Instead of such timer management, when an MO call corresponding to an MT call is received by one of the call processing servers 100, the record of the MT call table 104 of the other call processing server 100 is deleted. May be. That is, the call processing server 100 that has received the MO call notifies the other call processing server 100 of the identification information of the originator of the MO call, and the other call processing server 100 records the record corresponding to this identification information. Is deleted.

  The block diagram used in the description of the above embodiment shows functional unit blocks. These functional blocks (components) are realized by any combination of hardware and / or software. Further, the means for realizing each functional block is not particularly limited. That is, each functional block may be realized by one device physically and / or logically coupled, and two or more devices physically and / or logically separated may be directly and / or indirectly. (For example, wired and / or wireless) and may be realized by these plural devices.

  For example, the call processing server 100 according to an embodiment of the present invention may function as a computer. FIG. 7 is a diagram illustrating an example of a hardware configuration of the call processing server 100 according to the present embodiment. The call processing server 100 described above may be physically configured as a computer device including a processor 1001, a memory 1002, a storage 1003, a communication device 1004, an input device 1005, an output device 1006, a bus 1007, and the like.

  In the following description, the term “apparatus” can be read as a circuit, a device, a unit, or the like. The hardware configuration of the call processing server 100 may be configured to include one or a plurality of devices illustrated in the figure, or may be configured not to include some devices.

  Each function in the call processing server 100 is such that a predetermined software (program) is read on hardware such as the processor 1001 and the memory 1002 so that the processor 1001 performs an operation to perform communication by the communication device 1004, memory 1002, and storage. This is realized by controlling reading and / or writing of data in 1003.

  For example, the processor 1001 controls the entire computer by operating an operating system. The processor 1001 may be configured by a central processing unit (CPU) including an interface with peripheral devices, a control device, an arithmetic device, a register, and the like. For example, the restriction control unit 102 and the call management unit 103 may be realized by the processor 1001.

  Further, the processor 1001 reads a program (program code), software module, and data from the storage 1003 and / or the communication device 1004 to the memory 1002, and executes various processes according to these. As the program, a program that causes a computer to execute at least a part of the operations described in the above embodiments is used. For example, the call processing server 100 may be realized by a control program stored in the memory 1002 and operated by the processor 1001, and may be realized similarly for other functional blocks. Although the above-described various processes have been described as being executed by one processor 1001, they may be executed simultaneously or sequentially by two or more processors 1001. The processor 1001 may be implemented by one or more chips. Note that the program may be transmitted from a network via a telecommunication line.

  The memory 1002 is a computer-readable recording medium and includes, for example, at least one of ROM (Read Only Memory), EPROM (Erasable Programmable ROM), EEPROM (Electrically Erasable Programmable ROM), RAM (Random Access Memory), and the like. May be. The memory 1002 may be called a register, a cache, a main memory (main storage device), or the like. The memory 1002 can store a program (program code), a software module, and the like that can be executed to implement the wireless communication method according to the embodiment of the present invention.

  The storage 1003 is a computer-readable recording medium, such as an optical disc such as a CD-ROM (Compact Disc ROM), a hard disc drive, a flexible disc, a magneto-optical disc (eg, a compact disc, a digital versatile disc, a Blu-ray). (Registered trademark) disk, smart card, flash memory (for example, card, stick, key drive), floppy (registered trademark) disk, magnetic strip, and the like. The storage 1003 may be referred to as an auxiliary storage device. The storage medium described above may be, for example, a database, server, or other suitable medium including the memory 1002 and / or the storage 1003.

  The communication device 1004 is hardware (transmission / reception device) for performing communication between computers via a wired and / or wireless network, and is also referred to as a network device, a network controller, a network card, a communication module, or the like. For example, the MT reception unit 101, the MT control unit 105, the MO reception unit 106, the MO control unit 107, and the like described above may be realized by the communication device 1004.

  The input device 1005 is an input device (for example, a keyboard, a mouse, a microphone, a switch, a button, a sensor, or the like) that accepts an external input. The output device 1006 is an output device (for example, a display, a speaker, an LED lamp, etc.) that performs output to the outside. The input device 1005 and the output device 1006 may have an integrated configuration (for example, a touch panel).

  Each device such as the processor 1001 and the memory 1002 is connected by a bus 1007 for communicating information. The bus 1007 may be configured with a single bus or may be configured with different buses between apparatuses.

  The call processing server 100 includes hardware such as a microprocessor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a programmable logic device (PLD), and a field programmable gate array (FPGA). A part or all of each functional block may be realized by the hardware. For example, the processor 1001 may be implemented by at least one of these hardware.

  Next, operational effects of the call processing server 100 of the present embodiment will be described. In the call processing server 100, when the MO receiving unit 106 receives an MO call that is a positioning start request from the mobile terminal 200, the restriction control unit 102 receives the identification information (for example, IMSI) of the mobile terminal 200 and the third information. Restriction control is performed based on search target person information (for example, IMSI) that is a search target of a position positioning request (transmission of MT call) by person search. This makes it possible to accept a positioning start request according to a third party search even in a congested state.

  In the call processing server 100 of the present embodiment, when the call processing unit 103 receives a positioning start request from the mobile terminal 200 when the call processing server 100 is in a congested state, the identification information of the mobile terminal 200 is It is determined whether or not the search target person information stored in the MT call table 104 matches. When the call control unit 103 determines that they do not match, the restriction control unit 102 discards the positioning start request from the portable terminal 200, and when determined to match, the restriction control unit 102 is based on the positioning start request from the portable terminal 200. Thus, the MO control unit 107 is controlled so as to perform the SULP process for assisting the positioning.

  Thus, by accepting a request from the portable terminal 200 for identification information stored in the MT call table 104, a third party search that seems to be a highly urgent positioning request even when the call processing server is in a congested state. The positioning start request by can be accepted. Therefore, while reducing congestion in the call processing server, positioning processing by third party search that is highly urgent processing is enabled.

  Further, in this call processing server 100, the MT call table 104 stores information (call type) indicating whether or not the positioning request by the third party search requires urgency. Then, the restriction control unit 102 performs restriction control based on information (call type) indicating whether or not urgency is stored, which is stored in the MT call table 104.

  As a result, emergency MT-MO calls with urgency are not subject to regulation, and general MT-MO calls are subject to regulation, so that emergency MT-MO calls with high urgency are accepted even in a congested state. Make it possible.

  In this call processing server 100, the call management unit 103 stores the search target person information that is the search target of the positioning request by the third party search in the other call processing server 100. In general, there are a plurality of call processing servers 100, and MO calls are distributed to the respective call processing servers 100 by the LB 250 in such a manner that the processing load is evenly distributed. Therefore, the call processing server 100 that receives an MT call may be different from the call processing server 100 that receives an MO call. Even in such a case, by making the stored contents of each MT call table 104 the same, even if each call processing server 100 is in a congested state, an emergency MT-MO call or a general MT-MO call can be obtained. Can be accepted.

  The technique for synchronizing the MT call table 104 in this way is independent of the performance of the access processing for the shared disk, as compared with the case where the MT call table 104 is described in one shared disk described above. High-speed processing on the memory storing the table 104 is possible.

  In this call processing server 100, the timer 104 a measures the time for deleting the search target person information stored in the MT call table 104. When the timer 104 a counts a predetermined time, the call management unit 103 deletes the search target person information from the MT call table 104. Thereby, the search target person information is not stored in the MT call table 104 indefinitely, and the memory efficiency can be improved.
