Description

  The present invention relates to a mobile terminal, a control method, and a program. The present invention particularly relates to a mobile terminal having a function of measuring a current position, a control method in the mobile terminal, and a program for controlling the mobile terminal.

  2. Description of the Related Art Conventionally, a mobile terminal having a function of measuring a current position by GPS (Global Positioning System) or the like is known.

  For example, in Non-Patent Document 1, the current position of the mobile terminal is measured regularly in the background and automatically provided to the service provider simply by setting the mobile terminal in advance. A continuing arrangement is disclosed. In this case, the mobile terminal can obtain information related to the current position from the service provider.

  Patent Document 1 discloses a position detection device having a positioning function. The position detection device determines that the position detection device is in a stationary state when there is no change in the standby base station, and lengthens the positioning interval of GPS positioning. On the other hand, the position detection device pauses GPS positioning when GPS reception is not possible. On the other hand, when there is a change in the base station, the position detection device determines that the mobile station is in the moving state and performs GPS positioning in the normal mode. As described above, the position detection device does not use the GPS positioning result itself but determines the movement of the position detection device, and uses the communication result with the base station with low power consumption. For example, the position detection device changes whether the change in the reception level of radio waves from a specific base station and / or a neighboring base station is within a predetermined range, or changes to the position of the base station obtained by communication with the base station It is determined whether or not the camera is in a stationary state based on the determination of whether or not an error has occurred (whether or not the standby destination has changed).

  Patent Document 2 discloses a moving body monitoring system that uses GPS to monitor the entry and exit of a moving body with respect to a monitoring area. The mobile body monitoring system performs GPS positioning based on GPS signals received from GPS satellites. The mobile monitoring system stores monitoring area information representing a monitoring area. The mobile body monitoring system determines entry and exit to the monitoring area performed by the mobile body based on the current position of the mobile body obtained by GPS positioning and the previous positioning position. Furthermore, the mobile monitoring system calculates the distance between the current position and the boundary of the monitoring area. The mobile object monitoring system determines the time until the next GPS positioning using the distance as a criterion. The mobile monitoring system sequentially stores the results of GPS positioning. Thus, the mobile monitoring system reduces the number of positionings by increasing the time interval until the next GPS positioning. Thereby, the moving body can reduce power consumption.

  Currently, in 3GPP, with regard to W-CDMA (Wideband Code Division Multiple Access), LTE (Long Term Evolution), and LTE-A (Long Term Evolution Advanced), a small size is used for the purpose of expansion of service area and personal use. Standardization for the radio base station Home (e) NodeB is underway.

  The cell provided by Home (e) NB (hereinafter also referred to as “HeNB”) is an open cell that can be connected to all users, and a closed subscriber to which only a specific user is allowed access. A group cell (CSG cell: Closed Subscriber Group cell) and a hybrid cell having characteristics of both an open cell and a CSG cell exist.

  In addition, the proximity information (Proximity Indication) notified from the mobile terminal includes at least “enter” information indicating that the mobile terminal has approached the CSG cell described in the list of the mobile terminal, or the distance from the CSG cell. The information of “leave” indicating that it is to be included is included. That is, the proximity information is obtained when the mobile terminal determines that the mobile terminal has approached a CSG cell that can be accessed by handover from the macro cell, or that the mobile terminal has left the CSG cell during the handover operation. Information notified by the mobile terminal.

NTT docomo, “Auto GPS”, [online], [searched on January 23, 2011], Internet <URL: http://www.nttdocomo.co.jp/service/information/auto_gps/> 3GPP TS 36.331 v9.1.0 (2009-12): “Radio Resource Control (RRC)-Protocol Specification”

  The information related to the location information received from the service provider may include information unnecessary for the user of the mobile terminal. For example, when the user is at home, the user himself / herself is almost familiar with the information around the home, and therefore the user does not need to obtain the information so frequently. Similarly, information around the company where the user works or information around the school where the user attends school is often unnecessary for the user.

  Nevertheless, the mobile terminal periodically measures the current position of the mobile terminal, transmits position information indicating the current position to the service provider, and receives information related to the position information from the service provider.

For this reason, the mobile terminal consumes power wastefully. In the case where the mobile terminal is driven by a battery, consuming unnecessary power is a major disadvantage.

  Furthermore, since the mobile terminal stores unnecessary information related to the location information in the memory, the usable capacity of the memory is reduced. In addition, when a mobile terminal receives a service such as provision of information related to location information, it is considered that in addition to the information, the mobile terminal receives many mails related to the service. For this reason, the mobile terminal further consumes memory wastefully. In addition, mail management becomes difficult for the user.

  Further, in the position detection device of Patent Document 1, when the position detection device is stationary at the base station where the position detection device is located, it is possible to reduce power consumption by increasing the positioning interval. it can. However, the position detection device cannot reduce power consumption because the positioning interval does not become long in a moving state.

  Moreover, in the mobile monitoring system of Patent Document 2, when the mobile terminal is far from the monitoring area, the power consumption is reduced by increasing the positioning interval. However, in the mobile monitoring system, the position information of the monitoring area is managed by a monitoring server that communicates with the mobile terminal. For this reason, in a configuration such as a mobile monitoring system, it is possible to respond flexibly when a predetermined area such as a monitoring area moves or when a user of a mobile terminal easily adds an area.

  Hereinafter, a network system according to an embodiment of the present invention will be described with reference to the drawings. In the following description, the same parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

<Overview of network system>
FIG. 1 is a diagram showing an overview of a network system. Referring to FIG. 1, a network system 1 includes a mobile terminal 10, a base station 21 that constitutes a macro cell, small radio base stations (HOME (e) NodeB) 31, 32, 33, server devices 41, 42, 43. The network system 1 further includes base stations (not shown) other than the base station 21 and the small radio base stations 31 to 33. Moreover, the server apparatus with which the network system 1 is provided is not limited to three of the server apparatuses 41-43.

  The mobile terminal 10 receives signals transmitted from a plurality of GPS satellites 91, 92, 93, 94. Note that the number of GPS satellites is not limited to four. In addition, the mobile terminal 10 is communicably connected to the base station 21 in the state of FIG. The mobile terminal 10 is a mobile phone such as a smartphone. Each of the base stations 21, 31 to 33 is communicably connected to the server apparatuses 41 to 43 via a network.

  When the predetermined function is set to ON, the mobile terminal 10 performs the following process in the state of FIG. The mobile terminal 10 measures the current position of the mobile terminal 10 at a predetermined cycle (for example, 5 minutes) based on a signal transmitted from a GPS satellite. Specifically, the mobile terminal 10 receives a signal transmitted from a GPS satellite at the predetermined period and performs an operation for calculating the current position based on the reception of the signal. Next, the mobile terminal 10 wirelessly transmits position information representing the current position of the mobile terminal 10 (hereinafter also referred to as “current location information”) to the base station 21.

  The base station 21 accesses any of the server apparatuses 41 to 43 and acquires information related to the position information. The information related to the position information is various information related to the current position (for example, store information, weather information, parking lot information, sightseeing spot information, information unique to the local area). Hereinafter, information related to the position information is also referred to as “service information”. The base station 21 transmits the service information acquired from the server devices 41 to 43 to the mobile terminal 10. In this case, the mobile terminal 10 displays the service information transmitted from the base station 21 on the display.

  Hereinafter, since the operation mode of the mobile terminal 10 when the predetermined function is set to ON is an operation mode for automatically acquiring service information, it is also referred to as an “automatic acquisition mode”. .

  Next, the radio base stations 31 to 33 will be described. The radio base stations 31 and 33 are base stations that constitute a CSG cell that permits access of the mobile terminal 10. On the other hand, the radio base station 32 is a base station that constitutes a CSG cell that does not permit the mobile terminal 10 to access. The network system 1 may be configured to further include an open cell and a hybrid cell in addition to the CSG cell.

  For example, when handover from the base station 21 to the radio base station 31 is performed by the mobile terminal 10 moving in the automatic acquisition mode, the mobile terminal 10 , Referred to as “period T 1”), the current location information obtained by positioning is transmitted to the radio base station 31. Also in this case, the mobile terminal 10 receives service information based on the transmitted location information from any of the server devices 41 to 43 via the radio base station 31. The same processing is also performed when a handover from the base station 21 to the radio base station 33 is performed due to movement of the mobile terminal 10.

  On the other hand, since the mobile terminal 10 cannot access the CSG cell configured by the radio base station 32, even if the mobile terminal 10 enters the vicinity (Proximity Area) of the CSG cell, handover from the base station 21 to the radio base station 32 is not performed. Not executed. For this reason, even if the mobile terminal 10 transmits the current location information, service information based on the current location information cannot be obtained from any of the server devices 41 to 43.

Hereinafter, an outline of the operation of the mobile terminal 10 will be described with reference to FIGS.

FIG. 3A is a diagram showing a movement route of the mobile terminal 10. FIG. 3B is a diagram showing a positioning cycle. More specifically, FIG. 3B is a diagram showing the calculation period and timing of the current location information.

  With reference to FIG. 3A, the mobile terminal 10 moves along a first route 910. Specifically, the mobile terminal 10 passes through the CSG cell 310 and moves to a position in the cell 220. In this case, due to movement of the mobile terminal 10, handover from the base station 21 to the radio base station 31 and handover from the radio base station 31 to the base station 22 are performed.

  Referring to FIG. 3B, when the mobile terminal 10 is in the cell 210, the mobile terminal 10 repeats the positioning of the current position at a cycle T1. When the mobile terminal 10 moves from the cell 210 into the CSG cell 310, the mobile terminal 10 changes the positioning cycle from the cycle T1 (for example, 5 minutes) to a cycle T2 (for example, 60 minutes) longer than the cycle T1. When the mobile terminal 10 is in the CSG cell 310, the mobile terminal 10 repeats positioning at a cycle T2. Furthermore, when the mobile terminal 10 moves from the cell 310 into the cell 220, the mobile terminal 10 returns the positioning cycle from the cycle T2 to the cycle T1. When the mobile terminal 10 is in the cell 220, the mobile terminal 10 repeats positioning at a cycle T1.

  As described above, when the mobile terminal 10 detects that the mobile terminal 10 has entered the vicinity of the CSG cell 310 to which access is permitted, the mobile terminal 10 changes the positioning cycle from the cycle T1 to the cycle T2 longer than the cycle T1. change. Further, when the mobile terminal 10 detects that the mobile terminal 10 has exited from the CSG cell 310, the mobile terminal 10 changes the positioning cycle from the cycle T2 to the cycle T1.

  FIG. 4 is a diagram for explaining a positioning cycle by the mobile terminal 10 when the mobile terminal 10 moves on the second route. FIG. 4A is a diagram showing a movement route of the mobile terminal 10. FIG. 4B is a diagram showing a positioning cycle. More specifically, FIG. 4B is a diagram showing the calculation period and timing of the current location information.

  With reference to FIG. 4A, the mobile terminal 10 moves on the second route 920. Specifically, the mobile terminal 10 moves to a position in the cell 250 through the CSG cell 320 to which access is not permitted. In this case, handover from the base station 21 to the radio base station 32 is not performed due to the movement of the mobile terminal 10.

  Referring to FIG. 4B, when mobile terminal 10 is in cell 210, mobile terminal 10 repeats positioning of the current position at period T1. Even if the mobile terminal 10 moves from the cell 210 into the CSG cell 320, the mobile terminal 10 repeats the positioning cycle at the cycle T1. Further, even when the mobile terminal 10 moves from the cell 320 into the cell 250, the mobile terminal 10 repeats positioning at the cycle T1.

  As described above, the mobile terminal 10 does not change the positioning cycle when passing through the CSG cell 320 to which access is not permitted.

FIG. 5A is a diagram showing a movement route of the mobile terminal 10. FIG. 5B shows a positioning cycle. More specifically, FIG. 5B is a diagram showing the calculation period and timing of the current location information.

  With reference to FIG. 5A, the mobile terminal 10 moves along a third route 930. Specifically, the mobile terminal 10 moves to a position in the cell 260 through the CSG cell 330 to which access is permitted. In this case, due to movement of the mobile terminal 10, handover from the base station 21 to the radio base station 33 and handover from the radio base station 33 to the base station 26 are performed.

  Referring to FIG. 5B, when mobile terminal 10 is in cell 210, mobile terminal 10 repeats positioning of the current position at period T1. Even if the mobile terminal 10 moves from the cell 210 into the CSG cell 330, the mobile terminal 10 repeats positioning at the period T1. The reason why the mobile terminal 10 does not change the period is that the CSG cell 330 is associated with the period change flag “0”. Further, even when the mobile terminal 10 moves from the cell 330 into the cell 260, the mobile terminal 10 repeats positioning of the current position at the cycle T1.

  As described above, even when the mobile terminal 10 passes through the CSG cell 330 to which access is not permitted, when the acquisition cycle flag “0” is associated with the CSG cell 330, the mobile terminal 10 sets the positioning cycle. The period T1 is not changed to the period T2.

For example, the period change flag “0” is associated with the identification information “CSGC0001”, and the period change flag “1” is associated with the identification information “CSGC004”.

  FIG. 9 is a diagram showing the neighbor cell list 620. Referring to FIG. 9, neighboring cell list 620 is a list representing neighboring cells of each CSG cell that is allowed to be accessed by mobile terminal 10. For example, the identification information “CSGC0001” is associated with identification information “NBC0009”, “NBC0011”, “NBC0012”, and the like regarding the neighboring cells of the CSG cell specified by “CSGC0001”. Note that the identification information about neighboring cells is typically a physical cell ID (PCI).

  FIG. 10 is a diagram showing the position information list 630. Referring to FIG. 10, position information list 630 is a list representing position information of each CSG cell that is allowed to be accessed by mobile terminal 10. In the position information list 630, the identification information of the CSG cell to which access is permitted and the position information of the CSG cell specified by the identification information are associated for each CSG cell to which access is permitted. For example, identification information “CSGC0001” and position information “AREA0001” are associated with each other. Each piece of position information in the position information list 630 is information representing the range of the CSG cell specified by latitude and longitude.

  In the above, the storage unit 160 may store the CSG cell identification information, the period change flag, the neighboring cell identification information, and the CSG cell location information in association with each other. Need not be divided into three lists 610, 620, and 630. In addition, the mobile terminal 10 acquires CSG cell identification information, neighboring cell identification information, and CSG cell location information via a base station or a base station.

  Again, the process of the control unit 150 will be described with reference to FIG. The control unit 150 controls the operation of the mobile terminal 10. The control unit 150 controls the start and stop of positioning by the positioning unit 140, the positioning cycle, and the like. Further, the control unit 150 reads and writes data from the storage unit 160. Further, the control unit 150 controls the transmission process by the transmission unit 170 and the reception process by the reception unit 180. In addition, the control unit 150 stores the current location information calculated by the positioning unit 140 in the storage unit 160.

  The detection unit 151 of the control unit 150 uses the CSG list 610 to detect that the mobile terminal 10 has entered the vicinity of the CSG cell that is allowed to be accessed by the mobile terminal 10. Moreover, the detection part 151 detects that the mobile terminal 10 came out from the vicinity of the said CSG cell.

  The detection by the detection unit 151 can be performed by various methods. As a first example, the following technique is used. The detection unit 151 acquires information for specifying a neighboring cell from the base station that is in the area. The detecting unit 151 compares the acquired information specifying the neighboring cell with the neighboring cell list 620 (FIG. 10) stored in the storage unit 160 in advance in the CSG cell to which access is permitted. Detecting going in and out.

  As a second example, the following method is used. The detection unit 151 causes the positioning unit 140 to perform positioning. The detecting unit 151 compares the current location information obtained by positioning with the location information list 630 stored in advance in the storage unit 160, thereby detecting that access has been made to the CSG cell to which access is permitted. . Note that the detection unit 151 compares the current location information acquired at regular intervals as the current location information of the mobile terminal 10 with the location information list 630 stored in advance in the storage unit 160 to permit access. It may be detected that the user has entered or exited the CSG cell.

  The period changing unit 152 of the control unit 150 performs the following processing. When the mobile terminal 10 is detected in the vicinity of the CSG cell to which access is permitted and the period change flag of the CSG cell is “1”, the period changing unit 152 sets the positioning period as the default. The period T1 is changed to a period T2 longer than the period T1. In this case, the period changing unit 152 causes the transmitting unit 170 to transmit each current location information measured in the period T2. Typically, the period changing unit 152 causes the transmitting unit 170 to transmit each current location information at a period T2.

  Further, when the period changing unit 152 detects that the mobile terminal 10 has exited from the CSG cell, the period changing unit 152 returns the positioning period from the period T2 to the default period T1. In this case, the period changing unit 152 causes the transmitting unit 170 to transmit each current location information acquired in the period T1. Typically, the cycle changing unit 152 causes the transmitting unit 170 to transmit each current location information at a cycle T1.

  On the other hand, even if it is detected that the mobile terminal 10 has entered the vicinity of the CSG cell to which access is permitted, the period changing unit 152 has the period changing flag of the CSG cell “0”. Sometimes the positioning cycle is not changed. In this case, the period changing unit 152 continues to cause the transmitting unit 170 to transmit the current location information obtained by positioning in each period T1.

<Control structure>
FIG. 11 is a flowchart showing the flow of processing performed by the mobile terminal 10. Specifically, FIG. 11 is a flowchart showing a flow of processing after the operation mode of the mobile terminal 10 is switched to the automatic acquisition mode.

  Referring to FIG. 11, in step S2, application processor 105 performs initialization. Specifically, the application processor 105 sets all the period change flags in the CSG list 610 to “1”. In step S <b> 4, the application processor 105 determines whether an input for changing the cycle change flag from “1” to “0” is received from the user via the operation key 113.

  If the application processor 105 determines that the input has been accepted (YES in step S4), in step S6, the cycle change flag associated with the identification information of the CSG cell corresponding to the input is changed from “1” to “0”. . If application processor 105 determines that no input has been received (NO in step S4), the process proceeds to step S8.

  In step S8, the application processor 105 determines whether or not the mobile terminal 10 has entered the CSG cell in which access is permitted (specifically, in the vicinity of the CSG cell in which access is permitted). Use to detect. If application processor 105 determines that it has entered the CSG cell to which access is permitted (YES in step S8), in step S10, the period change flag associated with the CSG cell in which mobile terminal 10 has entered is “1”. It is judged whether or not. If application processor 105 determines that it is not in the CSG cell to which access is permitted (NO in step S8), it advances the process to step S8.

  If application processor 105 determines that the period change flag is “1” (YES in step S10), it changes the positioning period from period T1 to period T2 in step S12. On the other hand, when application processor 105 determines that the period change flag is “0” (NO in step S10), the process proceeds to step S8. In this case, in step S <b> 8, the application processor 105 determines whether another CSG cell to which access is permitted has been entered.

  In step S <b> 14, the application processor 105 determines whether the access has been permitted from the CSG cell by the above-described method. If the application processor 105 determines that the access has been made from the CSG cell to which access is permitted (YES in step S14), the positioning cycle is changed from the cycle T2 to the cycle T1 in step S16. That is, the application processor 105 returns the positioning cycle to the default cycle. If application processor 105 determines that it is not out of the CSG cell to which access is permitted (NO in step S14), it advances the process to step S14.

  In step S18, the application processor 105 determines whether or not an input for stopping positioning has been received. That is, the application processor 105 determines whether or not an instruction to cancel the setting of the operation mode and the automatic acquisition mode has been received from the user via the operation key 113. If application processor 105 determines that an input has been received (YES in step S18), the series of processing ends. If application processor 105 determines that no input has been received (NO in step S18), the process proceeds to step S8.

<Summary of mobile terminal 10>
(1) The mobile terminal 10 receives (i) a positioning unit 140 that measures the current position of the mobile terminal 10 in a predetermined cycle, and (ii) position information that represents the current position via the base station. A transmission unit 170 that transmits to the server device, (iii) a reception unit 180 that receives service information related to location information from the server device via the base station, and (iv) access by the mobile terminal 10 is permitted. A storage unit 160 for storing a CSG cell list (UEs CSG Whitelist) 610 including identification information (CSG IDs) of each of the CSG cells that are being accessed, and (v) the access is permitted using the CSG list 610 A detection unit 151 that detects that the mobile terminal 10 has entered the proximity (Proximity Area) of the existing CSG cell; and (vi) detection that the mobile terminal 10 has entered the vicinity of the CSG cell to which access is permitted. When A period changing unit 152 that changes the positioning period from the period T1 to the period T2 longer than the period T1.

  Therefore, when the mobile terminal 10 enters the vicinity of the CSG cell to which access is permitted, the mobile terminal 10 lengthens the positioning cycle of the current position. Therefore, the mobile terminal 10 can achieve low power consumption compared to a configuration in which the positioning cycle is not lengthened.

  In addition, the mobile terminal 10 reduces the amount of service information received that is considered unnecessary for the user, compared to a configuration in which the positioning cycle is not changed as described above. Therefore, the mobile terminal 10 can prevent the usable capacity of the memory from being reduced due to the presence of service information not intended by the user.

  Furthermore, since the mobile terminal 10 stores the CSG list 610, when a CSG cell to which access is permitted moves, or to add a CSG cell that the user of the mobile terminal 10 can easily access. Can do.

  As described above, the mobile terminal 10 can be reduced in power consumption and is a highly convenient terminal for the user.

  In particular, the CSG cell is a cell configured by a small radio base station (HOME (e) NodeB). In addition, the CSG cell to which access is permitted is usually a cell configured by a small radio base station installed in the vicinity of a place frequently used by users. Therefore, since the mobile terminal 10 lengthens the positioning cycle at a position familiar to the user, such as the user's home, work place, and school, the reception of service information related to the position can be reduced.

  (2) Moreover, the detection part 151 further detects that the mobile terminal 10 came out from the vicinity of the CSG cell to which access is permitted. When it is detected that the mobile terminal 10 has exited from the vicinity of the CSG cell to which access is permitted, the period changing unit 152 changes the positioning period to the period T2 when the positioning period is changed to the period T2. To period T1.

  Accordingly, when the mobile terminal 10 leaves the CSG cell to which access is permitted, the mobile terminal 10 returns the positioning cycle to the original cycle T1. Therefore, the user can acquire service information at more positions from the server device than the configuration in which the period T2 is maintained.

  (3) More specifically, the storage unit 160 further stores a period change flag indicating whether or not to change the positioning period from the period T1 to the period T2, in association with each of the identification information. . When the period change flag indicates that the period of positioning is changed from the period T1 to the period T2, the period changing unit 152 indicates that the mobile terminal 10 has entered the vicinity of the CSG cell to which access is permitted. When detected, the positioning cycle is changed from cycle T1 to cycle T2. On the other hand, if the period change flag does not indicate that the positioning period is changed from the period T1 to the period T2, the period changing unit 152 has entered the mobile terminal 10 in the vicinity of the CSG cell to which access is permitted. Is detected, the positioning cycle is not changed from the cycle T1 to the cycle T2.

  Therefore, the mobile terminal 10 determines whether or not to change the positioning cycle according to the state of the cycle change flag. Therefore, a user designates a CSG cell whose positioning cycle is to be changed and a CSG cell which is not to be changed among CSG cells whose access is permitted by making an input for changing the state of the cycle change flag to the mobile terminal 10. can do. For this reason, the mobile terminal 10 becomes a more convenient terminal for the user.

<Modification>
(1) In the above, when it is detected that the mobile terminal 10 has entered the vicinity of the CSG cell to which access is permitted, and the cycle change flag of the CSG cell is “1”, the positioning cycle is set to the cycle. The configuration for changing from T1 to the cycle T2 has been described.

  Below, the structure provided with a stop flag as a CSG list 610 instead of a period change flag is demonstrated. The contents of the stop flag will be described as being the same as the cycle change flag in FIG.

  In the following, when it is detected that a mobile terminal has entered the vicinity of a CSG cell to which access is permitted, and the stop flag of the CSG cell is “1”, the mobile terminal 10A that stops positioning Will be described. In other words, when it is detected that the mobile terminal 10 has entered the vicinity of the CSG cell to which access is permitted, and the stop flag of the CSG cell is “1”, the server apparatus via the base station The structure which stops transmission of the present location information to 41-43 is demonstrated. Note that the hardware configuration of mobile terminal 10A is the same as the hardware configuration of mobile terminal 10 (see FIG. 6), and therefore description thereof will not be repeated here.

  FIG. 12 is a functional block diagram showing a functional configuration of mobile terminal 10A. Referring to FIG. 12, mobile terminal 10 </ b> A includes antenna 1041, positioning unit 140, control unit 150 </ b> A, storage unit 160, transmission unit 170, reception unit 180, and antenna 101. The control unit 150A includes a detection unit 151 and a stop unit 153. That is, the mobile terminal 10A is different from the mobile terminal 10 in that the mobile terminal 10A includes the stop unit 153 and does not include the period changing unit 152.

  The stop unit 153 performs the following processing. The stop unit 153 stops positioning at the positioning unit 140 when it is detected that the mobile terminal 10A enters the vicinity of the CSG cell to which access is permitted and the stop flag of the CSG cell is “1”. Let In this case, since new current location information is not calculated, the stop unit 153 causes the transmission unit 170 to stop transmitting current location information. That is, the transmission of the current location information by the transmission unit 170 is interrupted.

  Moreover, the stop part 153 will restart the positioning by the positioning part 140, if it detects that 10 A of mobile terminals came out from the said CSG cell. In this case, the positioning unit 140 calculates current location information with a default period T1. The stop unit 153 causes the transmission unit 170 to start regular transmission of current location information.

  On the other hand, even when it is detected that the mobile terminal 10A has entered the vicinity of the CSG cell to which access is permitted, the stopping unit 153, when the stop flag of the CSG cell is “0”, Does not stop positioning. In this case, the stop unit 153 continues to cause the transmission unit 170 to transmit the current location information calculated by positioning in each cycle T1. Also, the stop unit 153 does not stop the current location information even when entering a CSG cell where access is not permitted.

  FIG. 13 is a diagram for explaining a positioning cycle by the mobile terminal 10A when the mobile terminal 10A moves along the first route. FIG. 13A is a diagram showing a movement route of the mobile terminal 10A. FIG. 13B is a diagram showing a positioning cycle. More specifically, FIG. 13B is a diagram showing the calculation period and timing of the current location information.

  With reference to FIG. 13A, the mobile terminal 10 </ b> A moves on the first route 910. Specifically, the mobile terminal 10A moves through the CSG cell 310 to a position in the cell 220. In this case, a handover from the base station 21 to the radio base station 31 and a handover from the radio base station 31 to the base station 22 are performed by the movement of the mobile terminal 10A.

  Referring to FIG. 13B, mobile terminal 10A repeats positioning at period T1 when mobile terminal 10 is in cell 210. When the mobile terminal 10A moves from the cell 210 into the CSG cell 310, the mobile terminal 10A stops positioning. When the mobile terminal 10A moves from the cell 310 into the cell 220, it resumes positioning. 10 A of mobile terminals transmit the calculated present location information to the server apparatuses 41-43 via a base station. In addition, when the mobile terminal 10 is in the cell 220, the positioning is repeated at the cycle T1.

  As described above, when the mobile terminal 10 </ b> A detects that the mobile terminal 10 has entered the vicinity of the CSG cell 310 to which access is permitted, the mobile terminal 10 </ b> A stops positioning and moves to the current location information server devices 41 to 43. Stop sending Further, when detecting that the mobile terminal 10A has exited from the CSG cell 310, the mobile terminal 10A resumes positioning and resumes periodic transmission of the current location information to the server devices 41 to 43.

  When the mobile terminal 10A moves on the second route 920 shown in FIG. 4 (a), positioning is performed at the timing shown in FIG. 4 (b). When the mobile terminal 10A moves on the third route 930 shown in FIG. 5A, positioning is performed at the timing shown in FIG. 5B.

  FIG. 14 is a flowchart showing a flow of processing performed by the mobile terminal 10A. Specifically, FIG. 14 is a flowchart showing a flow of processing after the operation mode of the mobile terminal 10A is switched to the automatic acquisition mode.

  The flowchart shown in FIG. 14 is different from the flowchart shown in FIG. 11 in that step S12A is provided instead of step S12 and step S16A is provided instead of step S16. Therefore, step S12A and step S16A will be described below, and the description of the processing contents of other steps will not be repeated.

  In step S12A, the application processor 105 temporarily stops positioning. In step S16A, the application processor 105 resumes the positioning that has been temporarily stopped.

  Similarly to the mobile terminal 10, the mobile terminal 10A can prevent the available memory capacity from being reduced due to the presence of service information not intended by the user. Furthermore, since the mobile terminal 10A stores the CSG list 610, like the mobile terminal 10, the user of the mobile terminal 10A can easily access when the CSG cell to which access is permitted moves. Additional CSG cells can be added.

  As described above, the mobile terminal 10 </ b> A can be reduced in power consumption and is a highly convenient terminal for the user.

  In addition, the detection unit 151 further detects that the mobile terminal 10A has exited from the vicinity of the CSG cell to which access is permitted. When it is detected that the mobile terminal 10A has exited from the vicinity of the CSG cell to which access is permitted, the stopping unit 153 starts the positioning when the positioning is stopped.

  More specifically, the storage unit 160 further stores a stop flag indicating whether or not to stop positioning in association with each piece of identification information. When the stop flag indicates that the positioning is stopped, the stopping unit 153 performs positioning on the positioning unit 140 when it is detected that the mobile terminal 10A has entered the vicinity of the CSG cell to which access is permitted. Stop. On the other hand, when the stop flag does not indicate that the positioning is stopped, the stopping unit 153 does not stop the positioning even if the mobile terminal 10A is detected in the vicinity of the CSG cell to which access is permitted. .

  (2) In the above description, the period T2 has been described as a fixed value. However, the period T2 may be a variable value. The value of the period T2 may be based on an input from the user, for example. The setting timing of the cycle T2 is not particularly limited. For example, the mobile terminal 10 may be configured so that the mobile terminal 10 prompts the user to input the period T2 when entering the vicinity of the CSG cell to which access is permitted. Alternatively, the mobile terminals 10 and 10A may be configured to accept settings in steps S12 and 12A.

  (3) Further, in the mobile terminal 10, the positioning cycle is changed when the mobile terminal 10 enters the vicinity of a CSG cell whose cycle change flag is “1” among the CSG cells permitted to be accessed. Further, in the mobile terminal 10A, positioning is stopped when the mobile terminal 10A enters the vicinity of a CSG cell having a stop flag “1” among the CSG cells to which access is permitted. However, the present invention is not limited to this, and when the mobile terminal 10 enters the vicinity of all the CSG cells to which access is permitted, the mobile terminal 10, so as to change the positioning cycle and stop the positioning. 10A may be configured.
