Description

  The present invention relates to a location registration control system for performing location registration control of a mobile terminal by relaying a base station in a mobile radio network, in particular by dynamically changing the location registration area according to the remaining battery level of the mobile terminal, The purpose of the present invention is to provide a location registration control system that suppresses battery consumption of mobile terminals and extends battery life.

  A network control device that performs wireless communication between mobile terminals by relaying a base station transmits broadcast information for starting wireless communication to the mobile terminal, and sends a location registration request that is a response to the broadcast information from the mobile terminal. Received and performs location registration of the mobile terminal in response to the location registration request. The location registration is performed by selecting a Location Area; a location registration area (hereinafter referred to as LA) that specifies the location of the mobile terminal. The LA is composed of one or a plurality of cells as an area partitioned as a range where the radio waves of the base station can reach. In addition to periodic transmission from the mobile terminal, the location registration request is received from the mobile terminal when the mobile terminal is turned on or when the mobile terminal moves to a different LA across the boundary of the LA. Sent to the base station.

  However, each time the mobile terminal moves between LAs, the mobile station requests the base station for the location registration, so that the battery is wasted when moving compared to when stationary. For this reason, if the mobile terminal frequently moves between LAs, the mobile terminal has a problem that battery consumption increases in proportion to the movement frequency. Since mobile terminals are currently provided with various applications, the battery life is required to be significantly prolonged and the problem of battery consumption is required to be solved.

Some conventional location registration control systems improve the increase in control traffic on the network side by changing the location registration area according to the location registration of the mobile terminal and the number of incoming calls (see, for example, Patent Document 1). In addition, there is a conventional location registration control system in which the mobile terminal detects the remaining battery level and changes the reception frequency of the notification information and the location registration request frequency by control on the mobile terminal side (for example, Patent Documents). 2). In addition, the conventional location registration control system holds the number of times that the mobile terminal repeats cell reselection as cell-to-cell movement for a cell as a location registration area, and when the threshold for the number of cell reselection is exceeded. Some change the cell range (see, for example, Patent Document 3).

  However, the conventional location registration control system promotes running out of charge for a mobile terminal with a low battery level when the battery level of the mobile terminal is ignored and the location registration area is changed depending on the number of location movements and incoming calls. It has a problem of making it happen. Also, some conventional location registration control systems change the location registration area of only the mobile terminal according to the remaining battery level. In this case, communication between mobile terminals is reduced by reducing the frequency of location registration requests. There is a possibility that a time lag may occur in the communication synchronization between the network control device that relays the mobile terminal and the mobile terminal, and there is a possibility that a non-communication period during which the mobile terminal cannot be received may occur.

Thus, since the mobile terminal disclosed in the present application selects the location registration area of the optimal management level according to the remaining battery level, it is possible to perform the minimum required location registration request corresponding to the remaining battery level, Battery consumption can be suppressed.

  In addition, the mobile terminal disclosed in the present application includes a movement detection unit that detects whether movement between the location registration areas has occurred based on the location registration area specified by the area selection unit, if necessary, The location registration request generating means generates the location registration request information including the remaining battery level when the remaining battery level changes or when movement between the location registration areas occurs. As described above, the mobile terminal disclosed in the present application generates the location registration request information including the remaining battery level when the remaining battery level changes or when movement between the location registration areas occurs. The location registration request information reflecting the latest situation is transmitted to the network control device, so that cooperation accuracy of the location registration area with the network control device can be improved, and battery consumption can be more efficiently suppressed.

  Further, the mobile terminal disclosed in the present application is based on a periodic report unit that periodically outputs the location registration request information to the terminal-side transmission unit based on a certain periodic time, and on the basis of the remaining battery level. Reporting interval changing means for dynamically changing the period time. As described above, the mobile terminal disclosed in the present application periodically transmits the location registration request information to the network control device based on a cycle time dynamically set according to the remaining battery level. The location registration request information is periodically transmitted to the network control device at a frequency according to the remaining amount, and the latest location registration area is linked with the network control device while suppressing battery consumption. be able to.

  Further, the mobile terminal disclosed in the present application is provided with an incoming frequency detection means for detecting an incoming frequency based on the number of incoming calls that occurred within a certain time if necessary, and in the location registration request information as the incoming frequency increases. The battery is provided with an increased battery remaining amount and a battery remaining amount imitating means for imitating. As described above, the mobile terminal disclosed in the present application detects the incoming call frequency and considers that the battery remaining amount included in the location registration request information has increased with the increase of the incoming call frequency, and therefore frequently receives incoming calls. When receiving, the incoming call is made to the location registration area whose range is narrowed from the network control device, and the network load between the network control devices can be reduced.

  In addition, the mobile terminal disclosed in the present application may use the remaining battery level simulation unit based on the remaining battery level detected by the remaining battery level detection unit and the incoming call frequency detected by the incoming call frequency detection unit. Adjustment means for adjusting the degree of imitation of the remaining battery level is provided.

  The location registration control system disclosed in the present application is configured by combining the network control device and the mobile terminal. Thus, since the location registration control system disclosed in the present application is configured by combining the network control device and the mobile terminal, the location registration request information reflecting the latest situation can always be set, and the network The difference in recognition of the location registration area due to the time lag between the control device and the mobile terminal is suppressed to increase the setting accuracy of the location registration area, the battery consumption of the mobile terminal is suppressed, and the network load on the network control device is reduced. It can be realized efficiently.

  As shown in FIG. 2A, the battery remaining amount information 23a may include a battery remaining amount item and a battery remaining amount level item. This remaining battery level item indicates the remaining battery level as the remaining battery level of the mobile terminal 20 in watts. This battery remaining level item indicates the remaining battery level divided according to the remaining battery level. For example, the remaining battery level 1 to the remaining battery level 1, the remaining battery level 2 and the remaining battery level are determined. It can be divided into 3 and 3 stages.

  The user list DB can include a subscriber number item, a contract information item, an LA item, and a remaining battery level item, as shown in FIG. This subscriber number item indicates a number for identifying a user who is a subscriber who has contracted with the mobile terminal 20. The contract information item indicates contract information related to the user's mobile terminal 20. Further, this LA item indicates to which LA the mobile terminal 20 currently exists. Further, this battery remaining level item indicates the remaining battery level of the mobile terminal 20.

  Further, the terminal-side location registration area information 24a can include an LA item and a paging transmission destination cell item, as shown in FIG. This LA item indicates the LA name that identifies the LA. The paging transmission destination cell item indicates a cell included in the specified LA.

  Further, as shown in FIG. 3, the location registration control system according to the present embodiment can include an upper node 10A, a radio network device 10B, a base station 10C, and the mobile terminal 20. Here, the higher-level node 10A, the radio network device 10B, and the base station 10C correspond to the functional division of the network control device 10, and the control-side transmission unit 11 and the control Side receiving means 12 and the area setting means 13 for managing the control side location registration area information 13a. Further, each base station 10C recognizes a cell that is divided into a plurality of areas in which radio waves reach, for example, cells in a range in which radio waves reach from cells A to E.

  The upper node 10A includes the user list DB 13a-2 and performs user management and incoming call control of the mobile terminal 20. The wireless network device 10B includes the paging list DB 13a-1 and performs paging control. Further, the base station 10C transmits radio waves in units of the cell, and relays radio communication with the mobile terminal 20 according to control from the upper node 10A and the radio network device 10B.

The operation of the location registration control system of the present embodiment based on the above configuration will be described below.
First, as shown in FIG. 4A, the wireless network device 10B creates a paging list that defines the base station 10C and cells corresponding to each LA in the paging list DB 13a-1 (S1).

  This paging list is defined for each remaining battery level as shown in FIG. For example, LA defined by “LA1” includes cells 1-1 to 1-n of the base station 1 in the battery remaining level 1 with the largest remaining battery level, and in the battery remaining level 2 in the battery remaining level 2. The area of the base station 1 is expanded from the cell 1-1 to the cell 2-n.

  Further, LA defined by “LA1” includes an area expanded from the cell 1-1 of the base station 1 to the cell 4-n of the base station 2 at the battery remaining level 3 where the remaining battery level is the smallest. To do. As described above, since the LA as the location registration area is controlled for each mobile terminal 20 in accordance with the remaining battery level of the mobile terminal 20, the minimum required location registration corresponding to the remaining battery level can be performed. Resources can be used efficiently.

  Next, as shown in FIG. 4A, the wireless network device 10B notifies the base station 10C of LA information based on the paging list DB 13a-1 (S2). The base station 10C transmits the broadcast information to the mobile terminal 20 based on the LA information (S3).

  The mobile terminal 20 receives the notification information, detects the battery-remaining battery level indicated in the battery remaining amount information 23a by the battery remaining amount detection unit 23, and uses the area selection unit 24 to change the notification information to the notification information. Among the included LA information, LA information that matches the remaining battery level is registered in the terminal-side location registration area information 24a (S4). The remaining battery level is obtained by, for example, regularly using the remaining battery level information 23a to determine the remaining battery level and the threshold value by the remaining battery level detection means 23 using a threshold value for dividing the remaining battery level. It can be calculated in comparison. Further, the remaining battery level detecting means 23 registers the calculated remaining battery level in the remaining battery level information 23a. For example, when the remaining battery level is the remaining battery level 2, the area selecting unit 24 determines the LA shown in FIG. 5 (a-2) among the three LA information described in FIG. 5 (a). Information is selected and registered in the terminal side location registration area information 24a.

  Next, the mobile terminal 20 detects a change in remaining battery level when the movement detection unit 25 detects movement between LAs based on the terminal-side location registration area information 24a or when the remaining battery level detection unit 23 detects a change in remaining battery level. If the occurrence of a periodic timing corresponding to the period time is detected by the period report means 27, the position registration request information including the remaining battery capacity is generated by the position registration request generation means 26. This inter-LA movement is recognized, for example, when the mobile terminal 20 moves from cell A to cell D belonging to an LA different from cell A, as shown in FIG. As described above, since the mobile terminal 20 selects the LA with the optimum management level according to the remaining battery level, the mobile terminal 20 can perform the minimum location registration request according to the remaining battery level, thereby suppressing battery consumption. can do.

  As shown in FIG. 4B, the mobile terminal 20 sends the location registration request information including the battery remaining amount to the upper node 10A based on the terminal location registration area information 24a. (S11). As described above, the terminal-side transmission unit 21 transmits the position registration request information when the movement between LAs occurs or when the battery remaining amount changes in addition to the periodic transmission regarding the transmission of the position registration request information including the battery remaining amount. Since the information is transmitted, the location registration request information reflecting the latest situation is transmitted to the upper node 10A, and the cooperation accuracy of the LA with the upper node 10A is improved, and the battery consumption is more efficiently suppressed. be able to.

  Further, the reporting interval changing unit 271 can dynamically change the cycle time based on the remaining battery level detected by the remaining battery level detecting unit 23. For example, the reporting interval changing unit 271 can set the cycle time longer as the remaining battery level decreases. As described above, the mobile terminal 20 periodically transmits the location registration request information to the upper node 10A at a frequency according to the remaining battery capacity by dynamically setting the cycle time by the report interval changing unit 271. Thus, the latest battery remaining amount and LA can be linked with the upper node 10A while suppressing battery consumption.

  The upper node 10A receives the location registration request by the control-side receiving means 12, and registers the mobile terminal 20 in the user list DB 13a-2 based on the location registration request (S12). For example, as shown in FIG. 5B, the user list DB 13 a-2 is a user whose subscriber number is “bbbbbbbbbbbb” and whose contract information is “low class” and whose remaining battery level is “level 2”. When a location registration request located in LA indicated by “LA1” is received, the received content is registered by the area setting means 13. Further, the upper node 10A completes the location registration related to the mobile terminal 20 by the registration, and transmits a notification of the completion of the location registration to the mobile terminal 20 (S13). When receiving the notification, the mobile terminal 20 determines that the content of the transmitted location registration request is confirmed, and registers the content of the location registration request in the terminal-side location registration area information 24a (S14). .

  Next, as shown in FIG. 6, the upper node 10A receives the paging request as the incoming signal by the control side receiving means 12 when the incoming call arrives at the mobile terminal 20 (S21). Based on the user list DB 13a-2, the upper node 10A confirms the LA and the remaining battery level to which the destination mobile terminal 20 belongs by the area setting means 13 (S22).

  The upper node 10A transmits a paging request including the confirmed LA and remaining battery level to the wireless network device 10B (S23). The wireless network device 10B makes a paging request to the base station 10C belonging to the LA corresponding to the remaining battery level based on the paging list DB 13a-1. (S24).

  When the mobile terminal 20 that is the destination of the paging request is included in a cell managed by the base station 10C, the base station 10C transmits an incoming call request to the mobile terminal 20 (S25). The mobile terminal 20 receives the incoming call request from the base station 10C, makes an incoming call response to the wireless network device 10B, and starts communication (S26).

  In this way, the location registration control system, for example, as shown in FIGS. 7 and 8, the cells from cell A to cell E according to the remaining battery level divided into three remaining battery levels. Can be set for LA. As shown in FIG. 7A, the network control device 10 has a one-to-one correspondence with each cell from the cell A to the cell E when the remaining battery level is 1 as the maximum remaining battery level. With LA, LA from LA1 to LA5 can be set. In this case, the mobile terminal 20 transmits the location registration request to the network control device 10 for every inter-cell movement.

  Further, as shown in FIG. 4B, the network control device 10 sets the cell A and the cell B to LA1 when the remaining battery level is the battery remaining level 2 that is lower than the remaining battery level 1. The cell C and the cell D can be LA2, the cell E can be LA3, and the LA can be set for each base station. In this case, since the mobile terminal 20 transmits the location registration request to the network control device 10 every time the mobile station moves between base stations, the mobile terminal 20 transmits a frequency of transmission compared to when the location registration request is sent every time the mobile device moves between cells. Therefore, in a situation where the remaining battery level is relatively low, waste of battery consumption can be suppressed as compared with a case where the remaining battery level is sufficient.

  Further, as shown in FIG. 8, the network control device 10 sets the cell A, cell B, cell C and cell D as LA1 in the case of the battery remaining level 3 as the division with the smallest remaining battery. The cell E can be LA2 and the LA can be set across the base stations. In this case, since the mobile terminal 20 transmits the location registration request to the network control device 10 in a wider range of movement than between base stations, the mobile terminal 20 transmits a location registration request for each movement between base stations. In comparison, the transmission frequency is further suppressed, and waste of battery consumption can be minimized in a situation where the remaining battery level is considerably low.

  As described above, since the location registration control system disclosed in the present application is configured by combining the network control device 10 and the mobile terminal 20, it is possible to always set LA as location registration request information reflecting the latest situation. Thus, recognition differences due to setting time lags in the network control device 10 and the mobile terminal 20 are prevented to increase LA setting accuracy, and the battery consumption of the mobile terminal 20 is suppressed and the network load in the network control device 10 is reduced. It can be realized efficiently.

  The hardware configuration of the mobile terminal 20 according to the present embodiment includes a CPU, a memory, a storage device, a display, a wireless communication device, a numeric keypad, and a bus that connects the above-described units. The hardware configuration of the network control device 10 according to the present embodiment includes a CPU, a memory, a storage device, a display, a wireless communication device, and a bus connecting the above-described units.

(Second embodiment of the present invention)
Hereinafter, a location registration control system according to a second embodiment of the present invention will be described with reference to FIG. FIG. 9 is a block diagram showing the configuration of the location registration control system according to the second embodiment of the present invention.

Based on the remaining battery level detected by the remaining battery level detection unit 28 and the incoming frequency, In this configuration, an adjustment unit 291 that adjusts the degree of simulation of the remaining battery level by the remaining battery level simulation unit 29 is additionally provided.
The incoming call count information 28a counts and holds the incoming call count. The incoming call count information 28a again counts and holds the incoming call count from zero when a predetermined time has elapsed.

  Further, the location registration control system including the network control apparatus 10 and the mobile terminal 20 according to the present embodiment is similar to the upper node 10A and the wireless network, as in FIG. 3 describing the first embodiment. A device 10B, the base station 10C, and the mobile terminal 20 can be provided.

Hereinafter, an operation added to the first embodiment in the location registration control system of the present embodiment based on the above configuration will be described.
As shown in FIG. 6 described in the first embodiment, when the mobile terminal 20 receives an incoming request from the base station 10C in S25, the mobile terminal 20 sets the incoming number in the incoming number information 28a. Processing to count and hold is added. The incoming call frequency detection means 28 calculates and detects the incoming call frequency in a predetermined time based on the incoming call frequency information 28a.

  Next, as shown in FIG. 4B described in the first embodiment, the mobile terminal 20 receives the incoming call regarding the remaining battery level included in the location registration request information transmitted in S11. A process for calculating the remaining battery capacity according to the frequency is added. This deemed calculation is performed by the battery remaining amount simulation means 29 on the assumption that the remaining battery level included in the location registration request information has increased with the increase in the incoming call frequency.

  For example, the battery remaining amount simulation means 29 sets a threshold value for the incoming call frequency, and increases the remaining battery amount included in the location registration request information when the incoming call frequency exceeds the threshold value. it can. As described above, the battery remaining amount imitation means 29 considers that the battery remaining amount included in the location registration request information has increased with the increase in the incoming call frequency. Suppresses the expansion of the LA as a location registration area, and can reduce the network load due to communication with the network control device 10 at the time of an incoming call.

  In addition, the adjustment unit 291 may further adjust the value of the remaining battery level based on the absence calculation of the remaining battery level simulation unit 29 in consideration of the actual remaining battery level detected by the remaining battery level detection unit 23. it can. For example, the adjustment unit 291 is a case where the remaining battery level detected by the remaining battery level detection unit 23 is small even when the remaining battery level included in the location registration request information is increased by the deemed calculation. In this case, the increase amount of the remaining battery capacity can be reduced. As described above, the adjustment unit 291 adjusts the remaining battery level based on the battery level simulation unit 29 based on the remaining battery level, so that the optimum balance between the incoming call frequency and the actual remaining battery level is obtained. Therefore, only the remaining battery level calculation included in the location registration request information is adjusted, and optimal balance between reduction of network load and suppression of battery consumption by communication with the network control device 10 is realized. be able to.
