Description

  The present invention relates to a call control device and a restriction presence / absence determination method for performing priority control for each service.

  In the conventional call control device, when the load of the device exceeds a preset threshold value, that is, when congestion occurs, it is assigned to the subscriber who is the user of the subscriber terminal that transmits the signal. Depending on the subscriber priority assigned, regulation is performed. For example, when regulation is performed, processing is performed for signals up to a predetermined number of signals per unit time (for example, signal transfer), and processing for excess signals is not performed. Thereby, it is possible to reduce the load on the call control device in which congestion occurs.

  FIG. 1 is a connection diagram of a communication system according to the present embodiment.

  The traffic monitoring control system 1 is connected to the management system 2 via a communication line. The management system 2 is connected to two relay call control devices 3. Each relay call control device 3 is connected to a corresponding subscriber call control device 4. Each subscriber call control device 4 is connected to each other. Each subscriber call control device 4 may be connected to a subscriber call control device 4 that is not connected to any relay call control device 3. Each subscriber call control device 4 is connected to one or more subscriber terminals 5. Each relay call control device 3 is connected to the public switched telephone network 6. The user of the subscriber terminal 5 is called a subscriber. In the communication system, there may be more relay call control devices 3 than the two relay call control devices 3 illustrated. The same applies to the subscriber call control device 4 and the subscriber terminal 5, and there may be more subscriber call control devices 4 and subscriber terminals 5 than shown in the figure.

  The traffic monitoring and control system 1 is a device that monitors and controls traffic in a communication system. The management system 2 receives traffic information from each relay call control device 3 and transfers it to the traffic monitoring control system 1. The relay call control device 3 terminates the common line signal of the public switched telephone network 6 and transmits and receives signals to and from the subscriber call control device 4. The subscriber call control device 4 has a SIP proxy server function, a SIP location server function, and a SIP register server function, and controls IP telephones and the like.

  In the communication system shown in FIG. 1, a normal quality telephone service, a high quality telephone service, a videophone service, and a video on demand service are provided to the subscriber terminal 5. The provision of the service means that the subscriber can use the subscriber terminal 5 to make a call, a video conference, a video viewing, or the like.

  At that time, the subscriber terminal 5 transmits a signal to the subscriber call control device 4 in response to a subscriber operation or a signal transmitted from the subscriber call control device 4. The subscriber call control device 4 performs processing on the signal. For example, the subscriber call control device 4 transfers the signal to the relay call control device 3.

A restriction determination unit 42 for determination, a restriction level storage unit 43 for storing a restriction level indicating the degree of restriction, and a restriction information storage unit 44 for storing restriction information for determining presence / absence of restriction are provided.

  The restriction level storage unit 43 stores a restriction level indicating a degree of restriction so that the above-described processing such as signal transmission is not performed. The regulation levels are expressed as “primary”, “secondary”, and “tertiary” in order of the degree of regulation.

  The restriction information storage unit 44 includes a service priority storage unit 441 illustrated in FIG. 3A and a restriction information storage unit 442 illustrated in FIG.

  As shown in FIG. 3A, the service priority storage unit 441 has a service priority indicating the degree to which the corresponding service is preferentially provided for the service identification information indicating each of the plurality of services. It is stored in association. The service priority is represented by a numerical value such as “1”, “2”,.

  In FIG. 3B, the ◯ marks are information indicating that processing is performed as much as possible, that is, no restriction. On the other hand, the x mark is information indicating that processing is allowed with n signals per X second, that is, there is a restriction (however, the number of seconds X and the number n are preset). In addition, information that can be marked as “X” or “◯” (information of one cell) is referred to as “regulation information”. That is, the restriction information is for determining whether or not there is a restriction.

  In the restriction information storage unit 442, restriction information (regulation information for determining whether or not there is a restriction) for processing of the corresponding service is stored in association with each service priority.

  That is, in the restriction information storage unit 44, restriction information is associated with each service identification information.

  Further, the subscriber who is the user of the subscriber terminal 5 shown in FIG. 1 is assigned a subscriber priority indicating the degree of receiving the service preferentially. The subscriber priority is expressed as “GN”, “UR”, or “UR1” in ascending order.

  As shown in FIG. 3B, in the restriction information storage unit 442, restriction information is also associated with each subscriber priority. That is, in the restriction information storage unit 442, restriction information is associated with service identification information and subscriber priority.

  Further, the signal received by the subscriber call control device 4 is assigned signal type identification information indicating the type of the signal. The signal type identification information includes “general INV”, “emergency INV”, “REGIST”, “MESSAG”, and the like.

  As shown in FIG. 3B, in the restriction information storage unit 442, restriction information is also associated with each signal type identification information. That is, in the restriction information storage unit 442, restriction information is associated with service identification information and signal type identification information.

  Moreover, as shown in FIG. 3B, in the restriction information storage unit 442, restriction information is associated with each restriction level. That is, in the restriction information storage unit 442, the restriction information is associated with the service identification information and the restriction level.

  In FIG. 2, when a signal (hereinafter simply referred to as “signal”) is transmitted from the subscriber terminal 5 (hereinafter simply referred to as subscriber terminal 5) (S1), the signal processing unit 41 performs a service corresponding to the signal. Service identification information, signal type identification information of the signal, and subscriber priority of a subscriber who is a user of the subscriber terminal 5 are acquired. For example, the signal processing unit 41 acquires these according to the content of the signal. The signal processing unit 41 transmits the acquired service identification information, signal type identification information, and subscriber priority to the restriction determination unit 42, and requests the determination of the presence or absence of restriction (S3).

  When the restriction determination unit 42 is requested by the signal processing unit 41 to determine whether or not there is a restriction, the restriction determination unit 42 acquires the restriction level stored in the restriction level storage unit 43 (S5), and stores the service priority in the restriction information storage unit 44. The service priority associated with the transmitted service identification information is acquired from the unit 441 (S7). In addition, the restriction determination unit 42 acquires restriction information associated with the acquired service priority, the transmitted signal type identification information, the subscriber priority, and the acquired restriction level from the restriction information storage unit 442 ( S9) Based on the acquired restriction information, it is determined whether or not there is a restriction on the corresponding process (process corresponding to the signal).

  In the example of FIG. 3B, the restriction determination unit 42 associates, for example, service priority “1”, signal type identification information “general INV”, subscriber priority “UR”, and restriction level “tertiary”. Since the given restriction information (x mark) indicates that there is a restriction, a determination result that there is a restriction is obtained, and the determination result is transmitted to the signal processing unit 41 (FIG. 2: S11).

  The signal processing unit 41 sends a signal indicating that the processing cannot be performed to the subscriber terminal 5 if the determination result that there is a restriction is transmitted and the processing related to n signals has already been performed in the past X seconds. Transmit (S13). On the other hand, even if a determination result indicating that there is a restriction is transmitted, if processing regarding n signals has not yet been performed in the past X seconds, or if a determination result indicating that there is no restriction is transmitted, in step S1 Processing corresponding to the transmitted signal is performed.

  In the communication system of FIG. 1, the relay call control device 3 has the same function. However, in the case of the relay call control device 3, an IAM signal (a signal of a general call type in a normal quality telephone service) may be received from the public switched telephone network 6, and a determination result that there is a restriction is obtained. When processing corresponding to the signal cannot be performed, a disconnection signal (REL) is transmitted to the subscriber terminal 5.

  As described above, according to the subscriber call control device 4 and the relay call control device 3 of the present embodiment, whether or not there is a restriction on the processing of the corresponding service based on the restriction information associated with the service identification information. For example, in the case of a service that should be preferentially provided, processing is performed without restriction, and in the case of a service that is not so, processing is performed without restriction, so that the former service is performed. Can be preferentially provided.

  In addition, this Embodiment is an example, For example, you may make it not use one or more in a regulation level, subscriber priority, service priority, and signal type identification information. When the service priority is not used, the service priority storage unit 441 is eliminated, and the restriction information storage unit 442 may replace the service priority with service identification information.

  In addition, interactive services such as videophones are all the same service, and unidirectional services such as video-on-demand services are all the same service. Also good. In addition, services may be classified according to a difference in bandwidth value necessary for communication.

  For example, the type of voice, video, data, etc. can be specified by m = row of the signal (SDP), and the service may be classified by that type. Moreover, the direction of bi-directional, transmission only, reception only, no transmission / reception can be specified by a = line, and the service may be classified by the direction. Further, the bandwidth value can be specified by b = row, and the service may be classified by the bandwidth value.
