Description

  The present invention relates to a mobile communication system, and in particular, when a mobile communication network operator allocates a communication band in order to provide a service to a contracted subscriber, priority assignment regarding the communication band is performed in consideration of past communication quality. The present invention relates to a mobile communication system and a communication band priority control method that can be performed.

  In the conventional mobile communication system, the communication quality is defined for each service to be provided through the system, and the priority of the communication band is determined according to the communication quality. The subscriber enters into a contract with the mobile communication network operator for the service to be provided. The contract content includes communication quality (communication bandwidth). When providing a service to a contracted subscriber, the mobile communication network side allocates a communication band in consideration of the load state of the network and provides the service to the subscriber.

  However, in this type of conventional mobile communication system, it is not considered whether the subscriber has been provided with service with the contracted communication quality. Therefore, depending on the subscriber, there is a problem that the contracted service may not be received with the communication quality expected. That is, there is a problem that a subscriber may be assigned only a communication band according to an actual radio wave environment or a load state of a communication network, and may not satisfy a communication band assumed by the subscriber.

  As a technique related to this type of mobile communication system, for example, Patent Document 1 discloses a wireless distribution service that can assign a communication band according to the content of a contract with a user. In this wireless distribution service, a user connects to a terminal that provides a service with a bandwidth request. Then, the terminal inquires of the server about the contract contents of the user, compares the requested bandwidth with the contract contents, and determines whether a bandwidth corresponding to the contract contents is requested. The terminal that provides the contract allocates the requested bandwidth if the requested bandwidth is within the range of the contract content, and assigns the bandwidth by changing the bandwidth according to the contract content if the requested bandwidth is outside the range of the contract content.

  On the other hand, Patent Document 2 discloses a vehicular information communication system that can efficiently perform content acquisition by changing and resetting a data communication band for receiving content according to changes in a communication environment. Yes. In this vehicle information communication system, based on the effective communication speed predicted and calculated by the effective communication speed prediction device, the allocation of the data communication band of each content is changed according to the change of the communication environment in the data communication band calculation device. I try to reset it.

  Patent Document 3 discloses a communication control device that obtains an appropriate priority according to the content of each communication and performs quality control of each communication according to the priority. In this communication control device, the priority calculation means follows the priority calculation rules based on the communication form (conference, lecture, etc.) of communication between client devices and the attributes (posts, etc.) of users participating in the communication. Calculate the priority. On the other hand, based on the calculated priority, the bandwidth calculation means calculates a communication bandwidth to be allocated to the communication of the priority according to the bandwidth calculation rule.

A step of subtracting from the priority point held for the subscriber terminal, and a step of notifying the subscriber terminal of the notification of completion of allocation of the priority allocation communication band and the priority point after the subtraction. May be.

  In this communication band priority control method, when the calculated communication band exceeds the contracted communication band, the calculated communication band is allocated to the subscriber terminal to the mobile communication network. The indicating step is executed.

  In this communication band priority control method, it is preferable that the current location of the subscriber terminal is taken into account when generating the priority point.

  In this communication band priority control method, the mobile communication system may further include a priority transaction server that mediates transfer of priority points between subscriber terminals of all subscribers. In this case, to the subscriber terminal, the calculated communication band, the priority point given to the subscriber terminal, and the priority assigned communication band are transmitted to determine whether the priority assigned communication band is used. In the inquiry step, a step of inquiring whether or not there is an intention to transfer the priority point is executed. Subsequently, when receiving a notification indicating the transfer of the priority point from the subscriber terminal, subtracting the transferred priority point from the priority point held for the subscriber terminal; and the priority transaction server The priority points to be transferred to the subscriber terminals of all subscribers upon receiving notification of the priority points to be transferred from the management server. A step of notifying that there is a point, and a notification of requesting acquisition of the priority point from one or more subscriber terminals, selecting one subscriber terminal from the one or more subscriber terminals, The subscriber terminal that makes a successful bid for the priority point is determined, the successful bid is notified to the determined subscriber terminal, and the subscriber terminal that has made a successful bid to the management server When receiving notification of the successful bid subscriber terminal from the priority transaction server, the priority point awarded for the successful bid subscriber terminal is added to the priority point held and added. And a step of notifying the successful bidder subscriber terminal of the priority point.

[First Embodiment]
A first embodiment of a mobile communication system according to the present invention will be described with reference to FIG.

  Referring to FIG. 1, the mobile communication system according to the first embodiment includes a communication band management server 20 and a mobile communication network monitoring device 30, and includes a subscriber terminal 10, a communication band management server 20, and a mobile communication network. The monitoring devices 30 are connected to each other via a mobile communication network 40.

  The subscriber terminal 10 is a mobile phone terminal, for example, and includes a GPS (Global Positioning System) device 11. The GPS device 11 has a function of calculating the current position of the subscriber terminal 10 and outputting position information to the subscriber terminal 10. The subscriber terminal 10 has a function of transmitting wireless information and position information received from the GPS device 11 to the communication band management server 20. The radio information includes information on the received field strength and quality of the common pilot channel transmitted by the mobile communication network 40, measured by the subscriber terminal 10. The subscriber terminal 10 also has a function (display) for displaying communication band information and priority communication band information provided by the communication band management server 20.

  The communication band information includes a communication band calculated as currently available in the mobile communication network 40, which is calculated from the current network load information and the wireless information received from the subscriber terminal. The priority communication band information includes point-based priority point information given to subscribers and information on communication bands assumed to be provided when priority points are used.

  In addition, the subscriber terminal 10 has a function of transmitting the presence / absence of the priority point to the communication bandwidth management server 20 via the mobile communication network 40 by the operation of the subscriber, and also intends to transfer the priority point. It has a function of transmitting presence / absence to the communication band management server 20 via the mobile communication network 40. When the subscriber terminal 10 notifies the communication band management server 20 of the use of the priority point, if the communication band management server 20 notifies that the priority assignment of the communication band is permitted, the priority assignment is permitted. On the display, and notifies the subscriber that priority assignment has been performed.

  The communication band management server 20 is realized by an information processing apparatus such as a workstation server installed on the mobile communication network 40 side. The communication band management server 20 has a function of receiving the wireless information transmitted from the subscriber terminal 10, the position information, and information indicating the presence / absence of the priority point use / intention to transfer.

  The communication bandwidth management server 20 also includes wireless information notified from the subscriber terminal 10, location information, information indicating whether or not priority points are used, and network load information in the mobile communication network 40 notified from the mobile communication network monitoring device 30. The communication band assumed to be assignable to the subscriber terminal 10 is calculated based on the communication band, and the communication band assumed to be assigned when the subscriber selects the use of the priority point (priority assigned communication band). ). The communication bandwidth management server 20 calculates the communication bandwidth assumed to be assignable to the subscriber terminal 10 under the current network conditions calculated above, and the communication bandwidth contracted between the subscriber and the mobile communication network operator. If the communication bandwidth that can be provided under the current network conditions is much lower than the contracted communication bandwidth (below a certain threshold), it has the function to generate priority points. .

  The communication band management server 20 has a function of generating a result calculated by the above calculation function as assignable band information and transmitting it to the subscriber terminal 10. Also, the communication bandwidth management server 20 generates instruction information for instructing the mobile communication network 40 to preferentially assign a communication bandwidth to the subscriber when notified from the subscriber terminal 10 of the use of priority points. It has a function of transmitting to the mobile communication network 40.

  The communication band management server 20 has a function of managing a communication band contracted between a subscriber and a mobile communication network operator and a priority point of the communication band owned by the subscriber. This priority point information includes the number of points given in one procedure, the total number of points, the given subscribers and the given date and time. The mobile communication network operator can set the expiration date of the assigned priority points and the upper limit value of the accumulated priority points, thereby preventing endless assignment of priority points. In addition, the accumulated priority points can be applied to the billing discount for the subscriber.

  The mobile communication network monitoring device 30 is realized by an information processing device such as a workstation server installed on the mobile communication network 40 side, and the subscriber terminal 10 is located in response to a request from the communication bandwidth management server 20. The network load information of the base station being generated is generated and transmitted to the communication band management server 20.

[Description of operation]
Next, the operation according to the communication band priority control method realized by the mobile communication system will be described in detail with reference to the flowchart of FIG. It is assumed that all the subscribers referred to in the following are contracted with the mobile communication network operator.

  The subscriber accesses the communication band management server 20 from the subscriber terminal 10 (step A1). Subsequently, the subscriber terminal 10 transmits the current subscriber location information and radio information such as the received field strength and quality of the common pilot channel received from the mobile communication network 40 at the current location (step A2).

  In response to this, the communication band management server 20 accesses the mobile communication network monitoring device 30 that manages the network load status in the mobile communication network 40, and the network at the base station to which the subscriber is currently connected. Request load information (step A3).

  In response to this request, the mobile communication network monitoring device 30 transmits the current network load information to the communication bandwidth management server 20 (step A4).

  The communication band management server 20 first calculates an assumed communication band as a communication band that can be currently allocated based on the network load information obtained from the mobile communication network monitoring device 30. The communication band management server 20 compares the calculation result with the communication band contracted between the subscriber and the mobile communication network operator managed by the communication band management server 20 (step A5). When the calculated communication band is below the contracted communication band by a certain threshold or more, the communication band management server 20 generates a priority point and gives it to the subscriber of the subscriber terminal 10. Here, depending on the current subscriber position (for example, a position outside the service area assumed by the mobile communication network operator), the assumed communication band, that is, the assignable communication band is lower than the contracted communication band. Since it may be unavoidable, the communication band management server 20 generates a priority point in consideration of the current location of the subscriber and gives it to the subscriber (step A6). In other words, if it is unavoidable that the assignable communication band is lower than the contracted communication band, the priority point is not generated.

  The generated priority points are added to the subscriber priority points managed by the communication bandwidth management server 20. Next, the communication bandwidth management server 20 calculates an assignable communication bandwidth when the priority point is used (step A7).

  The communication band management server 20 transmits to the subscriber terminal 10 the communication band calculated by the operation, the priority point owned by the subscriber, and the communication band when the priority point calculated by the operation is used. Transmit (step A8).

  The subscriber terminal 10 displays the communication band information and priority point information received from the communication band management server 20 in the above operation on the display (step A9).

  The subscriber refers to the displayed information and selects whether or not the priority point is used on the display (step A10). In the display of the subscriber terminal 10, it is possible to always select whether or not to use the priority point. When the priority point is always used, the communication band information and the priority are selected. It is possible not to display the point information. In this case, step A9 and step A10 can be omitted. The subscriber terminal 10 transmits priority point usage information indicating whether to use the priority point to the communication bandwidth management server 20 (step A11).

  The communication band management server 20, when instructed to use priority points based on the priority point usage information received from the subscriber terminal 10, sets the communication band for the subscriber to the mobile communication network 40. A priority allocation is instructed, and the communication bandwidth calculated in step A7 when the priority point is used is transmitted as a bandwidth allocation amount (step A12).

  The mobile communication network 40 performs preferential allocation of communication bands to the subscriber terminals 10 based on the preferential assignment instruction received from the communication band management server 20 (step A13). After completing the communication band assignment, the mobile communication network 40 notifies the communication band management server 20 of the completion of the band assignment and the assigned communication band (step A14).

  When notified of the completion of band allocation from the mobile communication network 40, the communication band management server 20 subtracts the priority points owned by the subscriber based on the allocated communication band (step A15). The communication bandwidth management server 20 also notifies the subscriber terminal 10 of the remaining priority points and the completion of priority bandwidth allocation (step A16).

  When the communication band is preferentially allocated using the priority point, the fact that the priority band has been allocated is displayed on the display of the subscriber terminal 10 (for example, an excellent character in a circle is displayed). (Step A17).

  In step A5, when the calculated communication band is not lower than the contracted communication band by a predetermined threshold or more, the communication band management server 20 does not generate a priority point and calculates the calculated communication band. Is transmitted to the mobile communication network 40. The mobile communication network 40 performs communication band allocation based on the received communication band.

  If the subscriber is provided with only a communication band that does not satisfy the communication band (communication speed) specified in the contract with the mobile communication network operator by the operation as described above, A priority point is given, and the mobile communication network can provide communication in the contracted communication band preferentially in consideration of the priority point for the subscriber at the next and subsequent communication. As a result, the subscriber can communicate at a communication band contracted with the mobile communication network operator, that is, at a communication speed close to the communication speed. The reason is that it is possible to preferentially allocate bandwidths to subscribers.

  On the other hand, the mobile communication network operator can improve the customer satisfaction of the subscriber. In addition, since the information of the place where the priority point is given can also be obtained, it is possible to obtain area information for which future network improvement is desired, and it can be used as information for future expansion of mobile communication networks. .

[Second Embodiment]
Next, a second embodiment of the present invention will be described. In the second embodiment, when the subscriber selects whether or not to use the priority point on the display of the subscriber terminal, the priority point can be transferred in the first embodiment. And different. For this purpose, the mobile communication system has a priority transaction server 50 as shown in FIG. 3 in addition to the configuration shown in FIG.

  The operation of the second embodiment will be described with reference to the flowchart of FIG. The operation steps B1 to B9 from Step B1 at which the subscriber terminal 10 accesses the communication band management server 20 to Step B9 at which the communication band information and priority point information received from the communication band management server 20 are displayed on the display are as follows. Since it corresponds to steps A1 to A9 in the first embodiment, the description is omitted.

  The subscriber can select the transfer of the priority point by displaying the selection of the priority point transfer in addition to the selection of whether or not the priority point is used on the display of the subscriber terminal 10. (Step B10). When transfer of priority points is selected, the subscriber terminal 10 notifies the communication band management server 20 of transfer of priority points (step B11).

  The communication bandwidth management server 20 is notified of the transfer of the priority points previously given (including priority points already held) from the subscriber terminal 10, and therefore the priority given first to the subscribers. The point is deleted (step B12). Subsequently, the communication bandwidth management server 20 transmits the assigned priority point to the priority transaction server 50 (step B13).

  The priority transaction server 50 lists the priority points received from the communication bandwidth management server 20 on the server (step B14), and notifies the subscriber terminals registered in the priority transaction server 50 of the listing. (Step B15).

  A subscriber terminal (only one is shown as the subscriber terminal 60 here) that has received a priority listing notification from the priority transaction server 50 declares that when it wants to obtain a listed priority point (step) B16).

  The priority transaction server 50 selects, for example, on a first-come-first-served basis, one of a plurality of subscriber terminals that have desired acquisition, determines a subscriber terminal that makes a successful bid for a listed priority point, and determines the determined subscription The person terminal 60 is notified that the priority point has been awarded (step B17). The priority transaction server 50 also notifies the communication band management server 20 that the subscriber terminal 60 has acquired the priority point in order to match the priority point information (step B18).

  The communication band management server 20 adds the bid priority point to the priority point information of the managed subscriber terminal 60 (step B19). The communication band management server 20 also notifies the subscriber terminal 60 of the priority point information added in step B19 (step B20). Upon receiving this notification, the subscriber terminal 60 knows that it has made a successful bid for the priority point based on the priority point information added to the successful bid for the priority point information displayed on the display.

  When the subscriber selects the transfer of priority points in step B10, the communication band management server 20 transmits the communication band calculated in step B5 to the mobile communication network 40. The mobile communication network 40 performs communication band allocation based on the received communication band. In step B5, even when the calculated communication band is not lower than the contracted communication band by a certain threshold or more, the communication band management server 20 moves the calculated communication band without generating a priority point. Transmit to the communication network 40. Subsequent operations are as described in the first embodiment.

  According to the second embodiment of the present invention, in addition to the above-described effects of the first embodiment, a place where priority points can be traded between subscribers is provided, so that priority is given to other subscribers. Degree points can be transferred.
