Description

  The present invention relates to a communication control system and a communication control method.

  A mobile communication terminal such as a mobile phone or a PHS has a feature that, unlike a fixed telephone, it can communicate with other communication terminals while freely moving without being restricted to a specific place. On the other hand, when the other party of communication is a mobile communication terminal, the other party's mobile communication terminal can also move, so it is difficult to make a call by sensibly grasping the relative positional relationship between each other. Therefore, when there are customers from a distance or when meeting in an unfamiliar place, how close you are to each other when you contact each other using a mobile communication terminal before arriving at a destination such as a meeting place Such a relative positional relationship cannot be grasped, which may cause anxiety to the user of the mobile communication terminal. Therefore, there is a demand for a technique that can be sensuously grasped by, for example, sound, etc., to notify how close you are to a partner when making a call with a mobile communication terminal.

  In order to meet such a demand, for example, in the invention described in Patent Document 1, the identification number (CS-ID) of the base station in the wireless zone where one mobile communication terminal (waiting side) is located is determined at a predetermined timing. It is transmitted to the other mobile communication terminal (mobile side), and the other mobile communication terminal compares the transmitted CS-ID with the CS-ID of the base station where the mobile station is located. In other words, the mobile communication terminals are notified that they are close to each other. In the invention described in Patent Document 2, when both mobile communication terminals include a GPS information acquisition unit and a short-range communication unit and the short-range communication unit receives the GPS information of the other mobile communication terminal, it is based on the GPS information. The position was reported.

  However, the notification method described in Patent Document 1 determines whether a mobile communication terminal on the mobile side has entered the wireless zone in which the mobile communication terminal on the standby side is located, thereby determining the proximity region (for example, a radius of 200 to 300 m). In this case, the positional relationship between the two is grasped and notified. In addition, the notification method described in Patent Document 2 uses the short-range communication unit to exchange mutual GPS information so that the positional relationship between the two in a close-up area (for example, an area having a radius of 10 m where wireless communication is possible). It was a thing to grasp and notify. For this reason, in the notification methods described in Patent Documents 1 and 2, although it is possible to perform notification at the final stage immediately before both meet, the intermediate distance region (for example, the radius is several hundreds to 10 km) which is the previous stage. In the stage where both mobile communication terminals are located, the relative positional relationship between the two is grasped and notified, and the user of the mobile communication terminal is not relieved from a relatively early stage.

  Therefore, the present invention grasps the relative positional relationship between the two mobile communication terminals at an early stage, and performs notification according to the grasped positional relationship to at least one of the two mobile communication terminals. It is an object of the present invention to provide a communication control system capable of performing communication and the communication control method.

  In order to solve the above-described problems, a communication control system according to the present invention is a communication control system that controls communication between a transmitting terminal serving as a transmitting side and a receiving terminal serving as a receiving side among a plurality of mobile communication terminals.

A plurality of communication control systems comprising: location information storage means; and proximity information storage means for storing, for each identification number, neighboring cell information indicating neighboring cells located in the vicinity of the serving cell of each of the plurality of mobile communication terminals. Communication control method for controlling communication between a caller terminal serving as a caller and a callee terminal serving as a callee among the mobile communication terminals of the mobile communication terminal, wherein a call request signal including terminal specifying information for specifying the callee terminal is transmitted to the caller terminal If the call request signal is received in the reception step and the reception step, the cell information and neighboring cell information of the calling terminal and the receiving terminal specified by the terminal specifying information are stored. The acquisition step acquired from the information storage means and the proximity information storage means; the in-zone cell information of the calling terminal acquired in the acquisition step; the originating side cell group indicated by the neighboring cell information; and the presence of the receiving terminal acquired in the acquisition step. A determination step for determining whether or not at least a part of the receiving side cell groups indicated by the serving cell information and the neighboring cell information match, and the determination step determines that the calling side cell group and the receiving side cell group are at least a part of A sound change step for changing at least one of a ringing sound to the calling terminal and a ringing sound at the receiving terminal when it is determined that the call has been made.

  According to this communication control system or communication control method, in addition to the serving cell of each mobile communication terminal, information on neighboring cells located in the vicinity of the serving cell is stored, and the stored serving cell information and the neighborhood are stored. The relative positional relationship between the transmitting terminal and the receiving terminal is determined based on the cell information, and notification according to the determination result is performed. For this reason, the relative positional relationship between both mobile communication terminals can be grasped in a wide range. For example, the mutual positional relationship is grasped at a relatively early stage such as a distance of several hundred m to 10 km. And notification according to the grasped positional relationship can be performed to at least one of both mobile communication terminals. As a result, according to the communication control system and the communication control method described above, it is possible to give a sense of security to the user of the mobile communication terminal at a relatively early stage.

  The sound changing means may change the sound volume level according to the determination by the determining means, or may change the type of sound according to the determination by the determining means. In this case, since the contents of the sound by the sound changing means differ depending on the determination result, it is possible to grasp sensuously that both are approaching gradually.

  Further, it is preferable to further include an updating unit that updates the serving cell information stored in the serving information storage unit and the neighboring cell information stored in the neighboring information storage unit according to the movement of each of the plurality of mobile communication terminals. .

  Next, the communication control system 10 will be described. The communication control system 10 is a system that controls communication between the transmitting terminal 20A and the receiving terminal 20B. The communication control system 10 performs communication exchange between the mobile communication terminals 20, information on each area of the mobile communication terminal 20, and the like. It consists of an HLR (Home Location Register) to be stored. As shown in FIG. 1, the communication control system 10 functionally has a location information storage unit 11 (location information storage unit), an adjacent information storage unit 12 (neighbor information storage unit), and an update unit 13 (update). Means), an exchange control unit 14, an acquisition unit 15 (acquisition unit), a determination unit 16 (determination unit), and a sound change unit 17 (sound change unit).

  As shown in FIG. 2, the communication switching apparatus and the HLR constituting the communication control system 10 physically transmit / receive data to / from main storage devices such as the CPU 10a, ROM 10b, and RAM 10c, the mobile communication terminal 20, and the like.

Each function of the communication control system 10 reads predetermined computer software on hardware such as the CPU 10a, ROM 10b, RAM 10c, etc., thereby operating the communication module 10d under the control of the CPU 10a and the main storage devices 10b, 10c. And by reading and writing data in the auxiliary storage device 10e.

  The in-zone information storage unit 11 stores in-zone cell identification numbers (in-zone cell information) indicating the in-zone cells of the plurality of mobile communication terminals 20, and terminal identification numbers (such as IMEISV) for identifying the plurality of mobile communication terminals 20. It is a part to store every. As data indicating such a serving cell, for example, data as shown in FIG. 3A is stored in the visiting information storage unit 11.

  The adjacent information storage unit 12 stores, for each terminal identification number (such as IMEISV), an adjacent cell identification number (neighboring cell information) indicating an adjacent cell (neighboring cell) adjacent to a serving cell of each of the plurality of mobile communication terminals 20. Part. As data indicating such adjacent cells, for example, data as shown in FIG. 3B is stored in the adjacent information storage unit 12. Since adjacent cells in the data stored in the adjacent information storage unit 12 are adjacently arranged so as to cover one in-zone cell, there are usually a plurality of adjacent cells for one in-zone cell. It comes to correspond.

  The updating unit 13 updates the serving cell identification number stored in the serving information storage unit 11 and the neighboring cell identification number stored in the neighboring information storage unit 12 according to the movement of each of the plurality of mobile communication terminals 20. Part. When the location registration of the mobile communication terminal 20 is newly performed, the update unit 13 is located in the mobile communication terminal 20 in which location registration has been performed among the cell-specific numbers stored in the location information storage unit 11.

Following the update of the serving cell identification number, the update unit 13 changes the neighboring cell identification number of the mobile communication terminal 20 in which the serving cell is updated to the neighboring cell identification number corresponding to the updated serving cell identification number. And update. In addition, when updating the adjacent cell identification number, the update unit 13 performs update processing with reference to information (adjacency map) of the adjacent relationship of each cell stored in advance.

  The exchange control unit 14 includes a receiving unit 18 that receives a call request signal including terminal specifying information for specifying the receiving terminal 20B from the calling terminal 20A, and controls communication (circuit switching) between the calling terminal 20A and the receiving terminal 20B. It is a part to do. When receiving unit 18 receives a call request signal from call terminal 20A, exchange control unit 14 generates a call request signal and transmits the generated call request signal to call terminal 20B. In response to the transmission of the incoming call request signal, the exchange control unit 14 performs ringback (ringing of a ringing tone) to notify the calling terminal 20A that the receiving terminal 20B is being called. After receiving the incoming request signal, exchange control unit 14 receives the incoming response signal indicating that the incoming request is accepted from incoming terminal 20B, and transmits the received incoming response signal to outgoing terminal 20A. Thereby, the exchange control unit 14 ends the circuit exchange work between the transmitting terminal 20A and the receiving terminal 20B, and a call between both terminals is started.

  The acquisition unit 15 is a part that acquires the serving cell identification number and the neighboring cell identification number of each of the transmitting terminal 20A and the receiving terminal 20B. When the transmission request signal is received by the reception unit 18 (exchange control unit 14), the acquisition unit 15 receives a determination start signal for starting determination of the relative positional relationship between the terminals 20A and 20B from the exchange control unit 14. Receive. When receiving the determination start signal, the acquiring unit 15 stores the in-zone cell specifying number and the adjacent cell specifying number of the receiving terminal 20B specified by the transmitting terminal 20A and the terminal specifying information, and the in-zone information storing unit 11 and the adjacent information storing unit. 12 from. The acquisition unit 15 outputs the acquired in-zone cell identification number and adjacent cell identification number to the determination unit 16 in a state in which the acquisition cell 15 is associated with the terminal identification numbers of both terminals 20A and 20B.

  The determination unit 16 is configured to identify the serving cell group A indicated by the serving cell identification number and the neighboring cell identification number of the calling terminal 20A acquired by the acquiring unit 15 and the serving cell specification of the receiving terminal 20B acquired by the acquiring unit 15. This is a part for determining whether or not the called-side cell group B indicated by the number and the adjacent cell identification number is at least partially matched. In the present embodiment, when the determining unit 16 determines that the originating side cell group A and the terminating side cell group B are at least partially matched, the serving cells of both the originating side cell group A and the terminating side cell group B are A first determination that matches, a second determination that one in-zone cell of the originating side cell group A and the terminating side cell group B matches the other neighboring cell, an originating side cell group A and the terminating side cell group The determination is divided into the third determination in which only both adjacent cells of B match.

  In the first determination, it is determined that both terminals 20A and 20B are located in the same cell, and the distance between both terminals 20A and 20B is determined to be a very close distance such as 0 to 300 m, for example. The In the second determination, it is determined that both terminals 20A and 20B are located in different adjacent cells, and the distance between both terminals 20A and 20B is determined to be a short distance such as 300 m to 600 m, for example. The In the third determination, it is determined that both terminals 20A and 20B are located in different cells that are not adjacent to each other across one cell, and the distance between both terminals 20A and 20B is, for example, 600 m to It is determined as a medium distance such as 900 m. That is, the determination unit 16 determines the relative positional relationship between the two terminals 20A and 20B in the order of the first determination, the second determination, and the third determination step by step from the shortest distance between the both terminals 20A and 20B. To do. The determination unit 16 outputs the determination result thus determined to the sound change unit 17.

  The sound changing unit 17 is a part that changes the ringing tone to the calling terminal 20A and the ringing tone at the receiving terminal according to the determination result by the determining unit 16. When the determination result is input from the determination unit 16 and the determination unit 16 determines any one of the first to third determinations, the sound changing unit 17 uses a different ringing sound as the ringing sound. The volume information of the first ringback tone is generated. In addition, the sound changing unit 17 is normal when the determination unit 16 determines none of the first to third determinations (when the calling side cell and the called side cell do not match at all). Volume information of a second ringback tone that is a ringing tone is generated. The sound changing unit 17 outputs the generated volume information to the exchange control unit 14. The exchange control unit 14 to which the volume information is input includes the input volume information in the information for causing the ringback to be performed, and performs ringback to the transmission terminal 20A.

  In the volume information of the first ringback tone, the volume differs according to the three types of determinations of the first to third determinations, and the volume of the sound corresponding to the first determination is the largest, The volume decreases in the order of the sound corresponding to the second determination and the sound corresponding to the third determination. Each volume in the volume information of the first ringback tone is larger than the volume in the volume information of the second ringback tone. The user of the transmitting terminal 20A can perceive, for example, that the user of the calling terminal 20B is approaching (or moving away) from the user of the receiving terminal 20B, for example, by the volume of the ringing tone.

  The sound changing unit 17 receives the determination result from the determining unit 16 and, when the determination unit 16 determines any one of the first to third determinations, the ringing sound to be generated by the receiving terminal 20B. Is set in the incoming request signal generated by the exchange control unit 14. In the present embodiment, the ringing tone at the receiving terminal 20B is made to vary in volume according to the three types of determinations of the first to third determinations by this special flag, and the volume of the sound corresponding to the first determination Is the largest, and the volume is decreased in the order of the sound corresponding to the second determination and the sound corresponding to the third determination. In addition, the sound changing unit 17 does not set a special flag so that a normal ringing tone sounds at the receiving terminal 20B if none of the first to third determinations is made by the determination unit 16. . Each volume of the ringtone when the special flag is set is larger than the ringtone when the special flag is not set. The user of the receiving terminal 20B can perceive, for example, that the user of the receiving terminal 20B is approaching (or moving away) from the user of the transmitting terminal 20A due to the volume of the ringtone.

  Next, a communication control method in the communication control system 10 will be described with reference to FIG.

  When starting a call between the calling terminal 20A and the receiving terminal 20B, the calling terminal 20A generates a call request signal (step S1). The generated call request signal includes information such as a terminal identification number that identifies the calling terminal 20A and a terminal identification number that identifies the receiving terminal 20B. 20 A of transmission terminals transmit such a transmission request signal to the communication control system 10 (step S2).

  When the transmission request signal is transmitted in step S2, the receiving unit 18 of the communication control system 10 receives the transmitted transmission request signal (reception step, step S3). When receiving the transmission request signal, the exchange control unit 14 of the communication control system 10 extracts information such as a terminal identification number for identifying the transmission terminal 20A and the reception terminal 20B included in the transmission request signal from the transmission request signal. When each terminal identification number is extracted, the exchange control unit 14 generates an incoming call request signal corresponding to the call request signal and outputs a determination start signal including information such as the extracted terminal identification number to the acquisition unit 15.

  When the determination start signal is input, the acquisition unit 15 acquires the in-zone cell identification number and the adjacent cell identification number of both terminals 20A and 20B from the in-zone information storage unit 11 and the adjacent information storage unit 12 (acquisition step, Step S4). The acquisition unit 15 outputs the acquired cell identification numbers to the determination unit 16. When each cell identification number is input, the determination unit 16 determines whether or not the originating side cell group A and the incoming side cell group B are at least partially matched (determination step, step S5). When determining with the determination part 16 being in agreement, it divides into three steps like the 1st-3rd determination mentioned above, and determines a coincidence degree.

  If it is determined in step S5 that the originating side cell group A and the terminating side cell group B are at least partially matched, the process proceeds to step S6, and the sound changing unit 17 determines the first ringback tone according to the degree of coincidence. Is generated in three stages (sound changing step), and if it is determined that the originating side cell group A and the terminating side cell group B do not match at all, the process proceeds to step S7, where the second ringing sound, which is a normal ringing tone, is generated. Generate ringback tone volume information. The generated volume information is output to the exchange control unit 14. When volume information of the first ringback tone is generated in step S6, a special flag for changing the volume of the ringtone to one of three levels is set in the paging information used for the incoming request signal ( Sound changing step, step S8).

  Subsequently, the exchange control unit 14 transmits an incoming call request signal to the incoming terminal 20B (step S9). The receiving terminal 20B receives the transmitted incoming request signal (step S10), and determines whether or not a special flag is set in the incoming request signal. When it is determined that the special flag is not set, the receiving terminal 20B rings a normal ringing tone. When it is determined that the special flag is set, the receiving terminal 20B The ring tone corresponding to any one of the three levels corresponding to the degree of coincidence is determined (step S11).

  Subsequently, when the user of the receiving terminal 20B inputs an instruction to respond to the incoming call to the incoming terminal 20B in response to the ringing tone in step S11, the incoming terminal 20B generates an incoming call response signal (step S12). It transmits to the communication control system 10 (step S13).

  If it is determined in step S5 that the originating side cell group A and the terminating side cell group B match at least partly, the exchange control unit 14 sends the first ringback tone to the originating terminal 20A. The ringback according to the second ringback tone is performed on the calling terminal 20A when it is determined that the calling side cell group A and the called side cell group B do not match at all. Perform (step S14).

  When the ringback according to the first ringback tone is performed, the calling terminal 20A, the ringing tone according to any one of the three stages according to the degree of coincidence determined by the determination unit 16 Is ringed as a ringback tone, and when ringback according to the second ringback tone is performed, a normal ringing tone is ringed as a ringback tone (step S15). Thereafter, when the incoming call response signal is transmitted from the exchange control unit 14 of the communication control system 10 to the outgoing terminal 20A (step S16), the outgoing terminal 20A receives the incoming call response signal (step S17). When the calling terminal 20A receives the incoming call response signal, the line exchange between the calling terminal 20A and the receiving terminal 20B is completed, and the call between the both terminals 20A and 20B is started (step S18).

  According to the present embodiment, in addition to the serving cells of the mobile communication terminals 20A and 20B, information on neighboring cells adjacent to the serving cell is stored, and the stored serving cell identification number and neighboring cell identification number are stored. The relative positional relationship between the transmitting terminal 20A and the receiving terminal 20B is determined based on the above, and notification according to the determination result is performed. For this reason, the relative positional relationship between the two mobile communication terminals 20A and 20B can be grasped in a wide range. For example, the positional relationship between the two at a relatively early stage such that the mutual distance is 0 m to 900 m. And at least one of the mobile communication terminals can be notified according to the grasped positional relationship. As a result, according to the communication control system and the communication control method described above, it is possible to give a sense of security to the users of the mobile communication terminals 20A and 20B at a relatively early stage. In addition, since the determination is made using the location information that is centrally managed by the communication control system 10, it is not necessary to perform, for example, GPS positioning or complicated determination processing in each mobile communication terminal 20A, 20B. Battery consumption at the terminal can be suppressed.

  In addition, when the determination unit 16 determines that the originating side cell group A and the terminating side cell group B are at least partially matched, the determination unit 16 matches the serving cell of both the originating side cell group A and the terminating side cell group B. Both the determination of 1, the second determination that one cell in the originating cell group A and the terminating cell group B matches the other neighboring cell, and both the originating cell group A and the terminating cell group B The determination is divided into the third determination in which only the adjacent cells match. Then, the sound changing unit 17 changes the volume level of the ringing tone and the ringing tone in accordance with the stepwise determination as described above by the determining unit 16. For this reason, the two mobile communication terminals 20A and 20B are gradually approaching, such that the distance between the two is a medium distance such as 600 m to 900 m, a short distance such as 300 m to 600 m, and a very short distance such as 0 m to 300 m. The users of both mobile communication terminals 20A and 20B can be made to sense with a sound that both are gradually approaching according to the determination result. As a result, it is possible to give a sense of security to the users of the mobile communication terminals 20A and 20B.

  The updating unit 13 updates the serving cell identification number stored in the serving information storage unit 11 and the neighboring cell identification number stored in the neighboring information storage unit 12 according to the movement of each of the plurality of mobile communication terminals 20. Is further provided. For this reason, even if the mobile communication terminal 20 moves, each specific number is updated. Therefore, if the mobile communication terminal 20 on the waiting side has moved from the destination for some reason, the mobile communication terminal on the other side 20 can grasp the fact sensuously by the content of the notification.

  As mentioned above, although this invention was concretely demonstrated based on the embodiment, this invention is not limited to the said embodiment. For example, in the above embodiment, both the ringing tone and the ringing tone are changed according to the determination by the determination unit 16, but at least one of the ringing tone and the ringing tone is determined by the determination unit 16. You may make it change according to it. Further, in the above embodiment, the content of the sound has been changed by changing the volume of the ringtone or ringtone, but the content of the sound may be changed by changing the type of the ringtone or ringtone. .

  In the above embodiment, the determination unit 16 determines the match between the originating side cell group A and the terminating side cell group B, which is composed of the serving cell and the neighboring cell adjacent thereto, In addition, the determination unit 16 determines whether or not the calling side cell group A and the called side cell group B, each of which includes a neighboring cell including the adjacent cell (the cell adjacent to the cell in the neighboring cell) and the cell in the serving cell, coincide with each other. Alternatively, all cells within a predetermined distance range from the serving cell are regarded as neighboring cells, and a matching unit between the originating side cell group A and the terminating side cell group B composed of this neighboring cell and the serving cell is determined. You may make it determine by 16. In this case, since the distance between the transmitting terminal 20A and the receiving terminal 20B is farther away, the relative positional relationship between the two mobile communication terminals 20A and 20B can be grasped. Information corresponding to the grasped positional relationship can be given to at least one of them.
