Japanese Unexamined Patent Publication No. 2001-69565

By the way, using a mobile communication network, a positioning request by a third party is transmitted to an arbitrary mobile terminal, and a positioning start request by SUPL positioning is received from the mobile terminal, so that the positioning request from the third party is performed. A service for acquiring the location information of an arbitrary mobile terminal according to the above is generally known.

When attempting to use such a service when the mobile communication network or server is in a congested state, the degree of urgency of the positioning request by a third-party search is made by the method described in Patent Document 1. Can be regulated by. On the other hand, the positioning start request, which is a response to the positioning request by a highly urgent third-party search, is subject to regulation in a congested state because its source is not registered. Therefore, there may be cases where positioning is not performed by a highly urgent third-party search.

Therefore, in order to solve the above-mentioned problems, it is an object of the present invention to provide a call processing server capable of making 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-mentioned problems, the call processing server of the present invention includes a positioning request receiving unit that receives a positioning request for a mobile terminal by a third-party search in a call processing server that makes a communication connection with the terminal. For the storage unit that stores the searched person information of the mobile terminal that is the search target of the positioning request, the broadcast processing unit that stores the searched person information in another call processing server, and the mobile terminal. receiving a positioning request unit that performs positioning request, the positioning start request receiving unit that receives a positioning start request from the mobile terminal, when the call processing server is in a congestion state, the positioning start request from the mobile terminal Then, the other call processing server includes the identification information of the mobile terminal and the regulation control unit that performs regulation control for the positioning start request based on the searchee information stored in the storage unit. When the positioning start request is received from the mobile terminal, the regulation process is performed based on the stored searchee information.

According to the present invention, when a positioning start request is received from a mobile terminal, regulatory control is performed based on the identification information of the mobile terminal and the searched person information stored at the time of the positioning request by a third party search. As a result, for example, it is possible to perform regulatory control that accepts the positioning start request in response to a third-party search and regulates other positioning start requests. Since the positioning start request according to the third party search is an important process, priority should be given to such request, and other requests should be regulated by the third party search. Positioning processing can be reliably performed, and congestion in the call processing server can be reduced.
In particular, in general, there are a plurality of call processing servers, and positioning requests and the like are allocated to each call processing server in a distributed manner so that the processing load is even. Therefore, the call processing server that receives the positioning request may be different from the call processing server that receives the positioning start request. Even in such a case, by making the stored contents of each call processing server the same, it is possible to accept the positioning start request for emergency processing even if each call processing server is in a congested state.

According to the present invention, it is possible to make a positioning start request by a third party search even when the call processing server is in a congested state.

An embodiment of the present invention will be described with reference to the accompanying drawings. When possible, the same parts are designated by the same reference numerals and duplicate description is omitted.

FIG. 1 is a system configuration diagram of a communication system including the call processing server 100 of the present embodiment. As shown in FIG. 1, a plurality of call processing servers 100 are arranged on the network. Then, when a third-party search request for positioning is transmitted from the CP (content provider) or the emergency reporting agency 210 in accordance with the request from the search requester, the third party search request for positioning is transmitted via the GW 220 and the LB (load balancer) 230. A third party search request is transmitted to one call processing server 100. The GW 220 can specify the destination mobile terminal 200 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 the 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. The SMS storage / distribution server 240 transmits a control SMS indicating a third-party search request to the mobile terminal 200 in response to a request from the call processing server 100, and the mobile terminal 200 sends a control SMS indicating a third-party search request to the mobile terminal 200 based on the control SMS. Start positioning according to the search request. In the present embodiment, in order to perform positioning processing by SUPL, the mobile terminal 200 transmits a positioning start request to the call processing server 100. Similar to the above-mentioned LB 230, the LB 250 selects one call processing server 100 and transmits its positioning start request. Instead of the SMS storage / distribution server 240, it may be a push notification server for starting an application by WAP or the like.

Upon receiving this positioning start request, the call processing server 100 determines whether or not the positioning start request is subject to regulation according to the congestion state of the call processing server 100 and the degree of urgency of the positioning start request. do.

Next, the function of the call processing server 100 will be described. FIG. 2 is a functional block diagram showing the 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 (regulation control unit, congestion state determination unit), and a call management unit 103 (identification information determination unit, broadcast processing unit, deletion unit). ), MT call table (TBL) 104 (storage unit), timer 104a (timekeeping unit), MT control unit 105, MO reception unit 106, and MO control unit 107.

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

The regulation control unit 102 has the number of signals to be processed at the same timing when the call processing server 100 is congested (for example, when the CPU usage rate exceeds the congestion threshold value or due to the total amount of data regulation). Is in a regulated state that refuses to accept more than the specified number of signals (such as when the value exceeds the specified value), and when an MT call is received, an emergency call agency or the like is urgent based on the source of the MT call. It is a part that determines whether or not the transmission is from a sexual source and performs processing based on that determination. When the regulation control unit 102 receives an MT call from an urgent institution in a congested state, the regulation control unit 102 passes the MT call (emergency MT call) to the call management unit 103. Further, in the congested state, when an MT call (general MT call) from an institution with low urgency is received, the MT call is discarded without being passed to the call management unit 103. Further, when it is not in a congested state, all MT calls (general MT call and emergency MT call) are passed to the call management unit 103.

Further, the regulation control unit 102 responds to the type of MO-LR (Mobile Originated Location Request: hereinafter referred to as MO call in the present specification) indicating the positioning start request by SUPL transmitted from the mobile terminal 200 and the congestion state. And carry out regulatory processing. As will be described later, the type of MO call is determined by the call management unit 103. In addition, as the regulation processing, when the predetermined number of signals (the number of signals transmitted to and received from the call processing server including MT-MO call and MO call) becomes a predetermined value or more, the processing beyond that is regulated. Yes, but not limited to that.

The call management unit 103 determines by the regulation control unit 102 that it has received an urgent emergency call MT call in a congested state, or when it is not in a congested state, all MTs including a non-urgent MT call. When it is determined that a call (general MT call and emergency MT call) has been received, the identification information (for example, IMSI, MSISDN) to be searched is determined as to whether the call is a general MT call or an emergency MT call. The indicated call type is associated with the elapsed time since it was stored in the MT call table 104, and stored in the MT call table 104.

FIG. 3 is a diagram showing a specific example of the 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 passed since the call type or the like was stored according to the timer function of the timer 104a.

Although both the IMSI and MSISDN are stored, either one may be used to identify the mobile terminal. Further, the information is not limited to these, and may be any information that identifies the mobile terminal to be searched.

Further, 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 after the predetermined time has elapsed.

Further, when the MT call is received by the MT receiving unit 101 and the information is stored in the MT call table 104 in order to synchronize with the MT call table of the other call processing server 100, the call management unit 103 performs another Notify the call processing server 100 of the call type, IMSI and MSISDN. The other call processing server 100 also manages the elapsed time in association with each other.

Further, when the 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, which is the source of the MO call, is transmitted to the MT call table 104. Judge whether or not it matches the stored search target. If they match, it is determined that the MO call corresponds 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 has a mechanism for synchronizing with each other, but the present invention is not limited to this. 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 writing on such a single shared disk, it is possible to eliminate the timer processing by deleting the corresponding record when the processing for restricting the MT-MO call is completed. 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 storage / distribution server 240. The SMS / distribution server 240 causes the positioning process to be performed by transmitting the control SMS indicating the 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. Positioning processing using this MO call is defined in 3GPPTS 23.271.

The MO control unit 107 transmits the MO call to the GW 220 when the regulation control unit 102 does not regulate the MO call. The transmitted MO call is processed 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. 4 is a processing flow when the call processing server 100 receives the signal by the MT receiving unit 101.

When the MT call is received by the MT receiving unit 101 (S101), the regulation control unit 102 determines whether the call is an emergency call or a general call based on the source of the MT call (S101). Then, the regulation control unit 102 determines whether or not the CPU is in a congestion state based on, for example, whether or not the CPU usage rate exceeds the congestion threshold value (S103). If it is determined that the number is exceeded, it is determined that the regulation is in progress, 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 is not exceeded, all MT calls are passed 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 searched target. (S105). Further, the call management unit 103 notifies the other call processing server 100 of the call type information, the identification information of the search target, and the elapsed time, and synchronizes the MT call table 104 (S106).

Then, the MT call is transmitted to the mobile terminal 200 to be searched (S107). When the MT call is received, the mobile terminal 200 performs a process for starting positioning (transmission of the MO call).

FIG. 5 is a flowchart showing the processing of the call processing server 100 when the MO call for starting positioning is received from the mobile terminal 200. When the MO receiving unit 106 receives the MO call indicating the positioning start request by SUPL from the mobile terminal 200 (S201), the call management unit 103 reads out 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 the call type of the MO call is determined based on the identification information. S203).

Here, when stored in the MT call table 104, it is determined that the MO call corresponds to the emergency MT call (emergency MT-MO call) or the MO call corresponds to the general MT (general MT-MO call). Judged. If it is not stored, it is determined that the MO call does not correspond to the MT call, that is, the positioning is started by the user of the mobile terminal 200. In the present specification, such an MO call is referred to as an MO call alone.

Then, the regulation control unit 102 determines the degree of congestion (CPU usage rate, etc.) of the call processing server 100 (S204, S205). The regulation control unit 102 executes temporary regulation, two-time regulation, or no regulation depending on the state of congestion. When the regulation control unit 102 determines that the congestion state exceeds the primary threshold value and also exceeds the secondary threshold value (secondary threshold value> primary threshold value), the MO call alone and the general MT-MO call are performed. It is discarded (S206). The emergency MT-MO call is passed to the MO control unit 107 without being discarded, and processing for positioning by SUPL is performed (S208). The above-mentioned primary threshold value and secondary threshold value 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.

Further, when the regulation control unit 102 determines that the congestion state exceeds the primary threshold value but does not exceed the secondary threshold value, only the MO call alone is discarded (S207), and the general MT-MO call is discarded. And 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).

Further, when the regulation control unit 102 determines that the congestion state does not exceed the primary threshold value, it means that the regulation is not performed, so that all MO calls are not discarded and positioning by SUPL is performed. Is performed (S208). 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 of SUPL positioning.

In the present embodiment, the description will be made on the premise that the MO call is received, but the mobile terminal 200 may receive the position information itself determined by GPS.

Next, timer management of the MT call table 104 will be described. FIG. 6 is a flowchart showing a timer management process 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 counts them (S301). When the call management unit 103 determines that the timer 104a in each record has timed a predetermined time (S302), the corresponding record is deleted from the MT call table 104. (S303). In this way, the information about the old MT call does not remain in the MT call table 104, and the 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 in the MT call table 104 of the other call processing server 100 is deleted. You may. 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 has the record corresponding to this identification information. To delete.

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 for other functional blocks as well. Although it has been described that the various processes described above are executed by one processor 1001, they may be executed simultaneously or sequentially by two or more processors 1001. Processor 1001 may be mounted on one or more chips. The program may be transmitted from the network via a telecommunication line.

The memory 1002 is a computer-readable recording medium, and is composed of at least one such as a ROM (Read Only Memory), an EPROM (Erasable Programmable ROM), an EPROM (Electrically Erasable Programmable ROM), and a RAM (Random Access Memory). May be done. The memory 1002 may be referred to as 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, or the like that can be executed to carry out the wireless communication method according to the embodiment of the present invention.

It may consist of at least one (registered trademark) disk), smart card, flash memory (eg, 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 input device 1005 and the output device 1006 may have an integrated configuration (for example, a touch panel).

Further, each device such as the processor 1001 and the memory 1002 is connected by a bus 1007 for communicating information. Bus 1007 may be composed of a single bus, or may be composed of different buses between devices.

Further, the call processing server 100 includes hardware such as a microprocessor, a digital signal processor (DSP: Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), a PLD (Programmable Logic Device), and an FPGA (Field Programmable Gate Array). It may be configured by, and a part or all of each functional block may be realized by the hardware. For example, processor 1001 may be implemented on at least one of these hardware.

Next, the operation and effect 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 the MO call which is a positioning start request from the mobile terminal 200, the regulation control unit 102 receives the identification information (for example, IMSI) of the mobile terminal 200 and the third party. Regulatory control is performed based on the search target information (for example, IMSI) that is the search target of the positioning request (transmission of MT call) by the person search. This makes it possible to accept a positioning start request according to a third-party search even in a congested state.

Further, in the call processing server 100 of the present embodiment, when the call management 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 changed. It is determined whether or not the information matches the searched person information stored in the MT call table 104. Then, the regulation control unit 102 discards the positioning start request from the mobile terminal 200 when the call management unit 103 determines that they do not match, and when it is determined that they match, the regulation control unit 102 is based on the positioning start request from the mobile terminal 200. The MO control unit 107 is controlled so as to perform the SULP process for assisting the positioning.

As a result, by accepting the request from the mobile terminal 200 for the identification information stored in the MT call table 104, even if the call processing server is in a congested state, a third-party search that is considered to be a highly urgent positioning request. It is possible to accept the positioning start request by. Therefore, while reducing the congestion on the call processing server, it enables positioning processing by a third-party search, which is a highly urgent process.

Further, in the 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 is urgent. Then, the regulation control unit 102 performs regulation control based on the information (call type) stored in the MT call table 104 indicating whether or not it requires urgency.

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 can be accepted even in a congested state. Make it possible.

Further, in the call processing server 100, the call management unit 103 stores the searched person information, which is the search target of the positioning request by the third party search, in the other call processing server 100. Generally, there are a plurality of call processing servers 100, and MO calls are distributed to each call processing server 100 by LB 250 so that the processing load is even. Therefore, the call processing server 100 that receives the MT call and the call processing server 100 that receives the MO call may be different. 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 made. Can be accepted.

The technique of synchronizing the MT call table 104 in this way does not depend on the performance of access processing to the shared disk, as compared with the technique of describing the MT call table 104 on one shared disk described above. High-speed processing on the memory that stores the table 104 becomes possible.

Further, in the call processing server 100, the timer 104a clocks the time for deleting the searched person information stored in the MT call table 104. Then, when the timer 104a clocks the predetermined time, the call management unit 103 deletes the searched person information from the MT call table 104. As a result, the searched person information is not stored in the MT call table 104 forever, and the memory efficiency can be improved.
