Abstract

PROBLEM TO BE SOLVED: To provide a priority origination/termination control system and a priority origination/termination control method, capable of performing priority origination/termination control more finely to a disaster damaged region.SOLUTION: The number of call control is established for normal business and for disasters. According to the scale of a disaster, the number of call control for disasters is secured to be large. Origination/termination processing is performed with the number of call control for normal business, until the current number of call control exceeds the number of call control for normal business. If the current number of call control exceeds the number of call control for normal business, origination/termination processing is performed with the number of call control for disasters. In addition, if the current number of call control exceeds the number of call control for normal business, a call priority of a telephone set asking an origination/termination request is compared with the lowest call priority in calls during calling. When the call priority of the origination/termination request is greater, connected call during calling is disconnected, and priority connection processing is performed with respect to the origination/termination request.

Description

  The present invention relates to a communication system, and more particularly, to a priority call control system and a priority call control method for performing priority control of outgoing and incoming calls to a disaster occurrence area when a disaster such as an earthquake occurs.

  Conventionally, when a disaster such as an earthquake occurs, telephone use is concentrated in the affected area, which makes it difficult to make a call. Therefore, Patent Document 1 restricts call connection to a communication terminal located in an earthquake occurrence area, and for a communication terminal located in a specific area having a predetermined seismic intensity or more in the earthquake occurrence area. In some cases, communication systems have been proposed that do not restrict call connections.

  Further, in Patent Document 2, when there is an emergency call request from a mobile terminal in a state where all the call channels are blocked, among the call channels used by other mobile terminals with respect to the mobile terminal that has made an emergency call A channel capturing method has been proposed in which a channel that is not transmitting and receiving audio is captured, and an emergency call is given priority to make a call.

  Next, embodiments for carrying out the invention will be described in detail with reference to the drawings. The present invention preferentially processes incoming and outgoing telephone calls in a damaged area by performing priority control of outgoing and incoming calls when a disaster such as an earthquake occurs. Also, the present invention has two methods, and one is a method of performing priority connection of calls using the number of call controls for disaster and call priority. The other is a method for preferential connection of calls using only call priority.

(First embodiment)
First, an embodiment in which call priority connection is performed using the number of call controls for disaster and call priority according to the present invention will be described in detail. FIG. 1 is a block diagram showing an embodiment of a priority call control system according to the present invention. In the following embodiments, priority control when using an IP telephone will be described as an example.

  The SIP server 100 includes telephone number information 101, telephone position information (address information) 102, priority outgoing / incoming information 103 which is priority information for outgoing / incoming calls, and a call control number control system 120. Furthermore, it comprises a disaster monitoring system 110 that receives earthquake early warnings and the like. The telephone number information 101, the telephone position information (address information) 102, and the priority outgoing / incoming information 103, which is priority information for outgoing / incoming calls, are stored in the SIP server database. In the case of an IP telephone, position information (address information) is known from the IP address.

  The disaster monitoring system 110 performs event monitoring of disaster information. When the disaster monitoring system 110 acquires a disaster occurrence event, the disaster monitoring system 110 notifies the SIP server 100 of disaster location information and seismic intensity information (when an earthquake occurs). The SIP server 100 refers to the received location information of the disaster occurrence area, and from the location information (address information) 102 of all the phones corresponding to the phone number information 101 of the SIP server database being managed, Check if it is located in the disaster area. The SIP server 100 determines priority outgoing / incoming information 103 indicating the priority information of outgoing / incoming telephone calls managed based on the location information.

  For example, the priority incoming / outgoing information 103 is set to a larger value as the telephone is located closer to the center of the disaster occurrence area (the epicenter) when an earthquake occurs, and is set to a smaller value as the distance from the center of the disaster occurrence area increases. Specifically, the SIP server 100 determines the priority call information 103 for each telephone based on the position information for each telephone to be managed. That is, when an earthquake occurs, the SIP server 100 sets the highest-priority incoming / outgoing information 103 for a telephone located in a region having a maximum seismic intensity near the epicenter (such as a municipality) based on the disaster information from the disaster monitoring system 110. To do. For example, if an earthquake with a seismic intensity of 7 occurs, the highest priority call information is set for a telephone located in an area (such as a municipality) near the epicenter where the seismic intensity is the highest.

  In addition, the next highest priority incoming / outgoing information is set for telephones located in areas with seismic intensity 6 (such as municipalities), and the seismic intensity decreases in the same manner, such as areas with seismic intensity 5 and areas with seismic intensity 4. To set the priority call information to a small value. In this way, the SIP server 100 determines the priority call information 103 for each telephone managed. In addition, although priority outgoing / incoming information is set in units of municipalities (wards) notified by earthquake bulletins or the like, the present invention is not limited to this.

  FIG. 2 is a block diagram showing details of the call control number control system 120. When the call control number control system 120 receives a disaster information event from the disaster monitoring system 110, the call control number control system 120 determines the call number threshold value 122 from the disaster scale level, and sets the maximum controllable call number 121 to the normal call control number 123 and the disaster use number. To the number of call controls 124. The disaster call control number 124 is a call line reserved for the high priority by the priority call information 103.

  FIG. 3 shows an example of the call count control table. The maximum controllable number of calls is n. The call number control table is provided in the call control number control system 120. In the example of FIG. 3, an earthquake disaster is assumed, and the scale of the disaster is normally eight levels of level 1, level 2,. In addition, there is no earthquake in normal times, level 1 is seismic intensity 1, level 2 is seismic intensity 2,... Level 7 is seismic intensity 7, and the scale of disaster is defined according to the seismic intensity.

  As shown in FIGS. 2 and 3, the maximum controllable number of calls n is the sum of the number of normal control calls and the number of disaster control calls, but the number of disaster control calls increases according to the disaster scale. Secure. Specifically, the normal control call number na and the disaster control call number a are normal, but when the disaster scale is level 1, the normal control call number n-M1, the disaster control call number M1, and the disaster scale However, in level 2, it is assumed that the number of normal control calls n-M2 and the number of disaster control calls M2.

  Furthermore, at level 3, the number of normal control calls n-M3, the number of disaster control calls M3, at level 4, the number of normal control calls n-M4, the number of disaster control calls M4, ..., at level 7, the number of normal control calls It is assumed that n-M7 and the number of disaster control calls M7. However, a <M1 <M2 <M3 <M4 <M5 <M6 <M7. That is, as shown in FIG. 2, the call threshold value 122 is changed according to the disaster scale, and the normal control call count 123 is reduced and the disaster control call count 124 is secured as the disaster scale increases. The call control number control system 120 creates a call number control table in this way. FIG. 3 is an example of the call number control table, and the present invention is not limited to this.

  When the SIP server 100 receives an incoming / outgoing request in a state where the normal call control number 123 has been reached as will be described later, the SIP server 100 uses the priority outgoing / incoming information 103 of the calling side telephone and the priority outgoing / incoming information 103 of the incoming side telephone. Determine call priority. When the call priority is high, a control line is secured from the number of disaster call controls 124, and a call for call origination / reception is established. If the call priority is low, the call connection is rejected and the remaining number of call controls is secured.

  On the other hand, when the disaster call control number 124 is also lost, the call priority during a call is compared with the call priority of the outgoing / incoming request as described later. When the call priority during a call is low, the call during a call is disconnected and a call for making / receiving a call is established. If the call priority of the outgoing / incoming request is low, the outgoing / incoming request is rejected. When the SIP server 100 transfers a call to another relay server, it assigns call priority information in the Priority header. The relay server performs priority control of call control using the Priority header.

  Next, a specific operation of the present embodiment will be described with reference to FIGS. Here, an example will be described in which priority control is performed on incoming and outgoing calls to a damaged area when an earthquake occurs based on an earthquake occurrence notification from the disaster monitoring system 110. Further, an example in which call priority connection is performed using the number of call controls for disaster and call priority as described above will be described.

  FIG. 4 is a flowchart for explaining disaster information event processing. That is, the control operation of the call count control table when the disaster monitoring system 110 notifies the SIP server 100 of an event of disaster information will be described. First, the SIP server 100 waits for an event of disaster information (S201), and when the disaster monitoring system 110 receives the disaster information of earthquake early warning (S202), it notifies the SIP server 100 of the event.

  Upon receiving the disaster information event, the SIP server 100 determines the normal call control number 123 and the disaster call control number 124 by dividing the maximum controllable call number 121 according to the disaster scale (S203). At that time, as shown in FIG. 3, the call control threshold value 122 is determined so as to increase or decrease the call control number 124 for disaster according to the disaster scale of the earthquake, thereby determining the call control number corresponding to the disaster scale. If there is already a call and the call control number 124 at the time of disaster cannot be ensured, the call is not disconnected and the call is continued until another call request is generated.

  Next, the SIP server 100 confirms the location information (address information) 102 of the registered telephone (S204), and determines whether the managed telephone is located in the damage occurrence area (S205). If it is located in the damage occurrence area, the priority of the priority call information 103 of the corresponding telephone is set (S206). As described above, the priority outgoing / incoming information 103 is set to a larger value for telephones located in areas where the disaster scale is large. Priority call information 103 is set for all registered telephones.

  Further, the call priority in the call table of FIG. 7 is updated. The call table shows a list of calls that are currently in a call, and the call priority is updated from the priority call information on the caller side and the callee side of the call being notified. The call priority will be described in detail later.

  FIG. 7 shows an example of a call table. FIG. 7 shows a call that is currently in a call as a call number, and a call priority is set for each call. The call priority is, for example, a multiplication value of the priority transmission / reception information Xn of the telephone on the calling side and the priority transmission / reception information Yn of the telephone on the reception side, and sets the call priority for each call currently in a call. . In step S206 of FIG. 4, the SIP server 100 sets the priority call information 103 for the registered telephone, and updates the call priority as described above for the call that is currently in a call. The call table is created by a control unit (not shown) in the SIP server 100. The call priority is not limited to the multiplication value.

  FIG. 5 is a flowchart for explaining the outgoing / incoming call processing. The operation of the SIP server 100 when receiving a call request is described. First, the SIP server 100 waits for an outgoing / incoming call request (S211). When the incoming / outgoing request is received (S212), the SIP server 100 determines whether the normal call control number 123 can be processed (S213). If processing can be performed with the normal call control number 123, outgoing / incoming processing is performed with the normal call control number 123 (S217). At that time, the normal call control number and the disaster call control number are set according to the disaster scale in S203 of FIG. 4, and FIG. 3 shows an example of the call number control table.

  If the normal call control number 123 cannot be processed, the call priority is determined from the priority call information 103 of the caller telephone and the priority call information 103 of the callee (S214). As shown in FIG. 7, for example, the call priority is determined by the multipliers of the priority call information 103 of the caller telephone and the priority call information 103 of the callee telephone. If the call priority is low, the call connection is rejected (S218), and the remaining number of call controls is secured.

  Here, high and low call priority refers to, for example, low and high call priority. Therefore, a high call priority means that the call priority is higher than normal, and a low call priority means that it is a normal call priority (default value). Of course, the present invention is not limited to this, and it may be determined that the value is higher or lower than a preset value.

  On the other hand, if the call priority is higher than normal, it is determined whether or not processing is possible with the call control number 124 for disaster (S216). If the process can be performed with the disaster call control number 124, the outgoing / incoming process is performed with the disaster call control number 124 (S217). When the number of disaster call control 124 is not possible (S219), the process proceeds to the process of the flowchart of FIG. 6 (proceeds from B of FIG. 5 to B of FIG. 6). FIG. 6 shows processing when the number of disaster call controls is lost when a disaster occurs.

  When proceeding to B (S219) in FIG. 6, first, the number of calls in the damaged area is compared with the number of call control for disaster, and it is confirmed whether the number of calls in the damaged area has reached the number of call control for disaster. (S220). If the number of calls in the affected area has not reached the number of disaster call controls, the call with the lowest call priority is retrieved from the connected calls currently being called from the call table shown in FIG. 7 (S221). The call priority of the call that received the incoming call request is compared with the call priority of the retrieved call (S222). As a result, if the call priority of the call that has received the call request is lower than the call priority of the search call, the call is rejected (S226), and the process returns to A of FIG. 5 and waits for the call request. .

  On the other hand, if the call priority of the search call is lower than the call priority received the call request, the connected call during the call is disconnected (S224), and the call processing is performed (S225). When the outgoing / incoming call processing ends, the process returns to A in FIG. 5 and waits for an incoming / outgoing request. In S220, when the number of calls in the damaged area has reached the number of call control for disaster, the call is rejected (S226), and the process returns to A in FIG. Become.

  In the present embodiment, the disaster call control number is set according to the disaster scale, and the priority call processing is performed based on the call priority that reflects the location information of the caller and callee telephones. It is possible to perform outgoing / incoming control according to the situation, and to perform more detailed priority outgoing / incoming control for the damaged area.

  Also, when the number of disaster call controls reserved for disaster is lost, the call priority of the caller and receiver is determined, and this call priority is the current call priority. When the call priority is higher than the lowest, the connected call in a call is disconnected, so that a call with a high call priority can be secured even if the number of disaster call controls is lost.

  Furthermore, it is possible to construct a system only by adding simple functions such as ensuring a large number of disaster call controls according to the disaster scale. Therefore, a system can be easily constructed only by extending an existing system.

(Second Embodiment)
Next, an embodiment for performing call priority connection using only the call priority of the present invention will be described. In summary, the present embodiment performs priority connection control using only the call priority described in the first embodiment. Therefore, since the number of call controls for disaster in the system configuration of FIG. 1 is not required, the call control number control system 120 and the call number control table of FIG. 3 are not required. Other system configurations are the same as those in FIG.

  Next, the operation will be described. First, the event processing of disaster information will be described with reference to FIG. When priority connection is performed using only the call priority, it is not necessary to determine the normal call control number 123 and the disaster call control number 124. Therefore, the SIP server 100 waits for an event of disaster information (S201), and when receiving the event of disaster information (S202), confirms the registered location information (address information) 102 of the telephone (S204) (That is, whether the registered telephone is located in the disaster occurrence area) (S205).

  When the registered telephone is located in the disaster occurrence area, the priority of the priority call incoming / incoming information (103) of the corresponding telephone is set (S206). Also, the call priority during the current call in the call table of FIG. 7 is updated. Up to this point, the operation is the same as that described in the first embodiment. However, the process of S203 is not necessary.

  Next, the operation of the SIP server 100 when receiving an incoming / outgoing request will be described with reference to FIGS. First, the SIP server 100 waits for an incoming / outgoing request (S211). When the incoming / outgoing request is received (S212), the SIP server 100 proceeds to S214. Determine the call priority of the incoming request.

  Next, the process proceeds from S214 to S221 in FIG. 6, and the call with the lowest call priority is retrieved from the call table shown in FIG. 7 (S221), and the call priority and retrieval that received the call request are retrieved. The call priorities of the calls are compared (S222). As a result, if the call priority that received the call request is lower than the call priority of the search call, the call request is rejected (S226), and the process returns to A in FIG. 5 to wait for the call request. On the other hand, if the call priority of the retrieval call is lower than the call priority received the call request, the call in progress is disconnected (S224), and the call processing is performed for the call request (S225). When the outgoing / incoming process is completed, the process returns to A of FIG. 5 and waits for an incoming / outgoing request.

  In the present embodiment, the same effect as in the first embodiment can be obtained, but the configuration that does not require a call count control table can be further simplified.

  In the above embodiment, the priority call control for IP telephones in the damage occurrence area has been described as an example. However, the present invention can also be used when a mobile communication terminal other than an IP telephone is used. Can do. At that time, the mobile communication terminal may be equipped with a GPS function, and the position of the mobile communication terminal may be managed using the GPS function. Moreover, although the example of the earthquake disaster was given and the priority transmission / reception control of the communication terminal was demonstrated, this invention is not limited to this. For example, the present invention can be suitably used for disasters such as typhoons.

  The present invention can be suitably used for priority call control of a communication terminal in a damaged area when a disaster such as an earthquake or a typhoon occurs.
