Access network resource assignment rate data collection and management method using the audit procedure of bearer channel connection protocol

The present invention relates to a method for collecting and managing subscriber network resource allocation history information using an audit procedure of a bearer channel access protocol, and a computer-readable recording medium having recorded thereon a program for realizing the method.

In particular, in the case of a conventional subscriber network consisting of a switch and a subscriber transmission device that accommodates a V5.2 interface, a provisioning fee is provided for sharing a limited network resource of a V5.2 interface E1 link by multiple subscribers when the device is installed. The set value is hardly changed except when a physical failure of the V5.2 interface occurs, and the operator who manages the subscriber network uses the existing V5.2 interface bearer channel access (BCC) protocol to evaluate the aggregation cost. Information could not be collected.

Thus, if the subscriber access rate continues to exceed the predefined collection rate for the provisioned collection rate at the initial installation of the device, some subscribers may not be able to provide communications services for any amount of time, especially for times of high volume. There was a problem that it could not be provided and it was difficult for the operator to quickly take action to solve the problem.

In summary, the aggregation function of the V5.2 interface is performed by provisioning the aggregation cost when the subscriber network transmitter and the switch are initially installed, and this aggregation function is a network resource (E1 link time) in which all subscribers connected to the subscriber network transmitter are limited. This technology was introduced to promote efficient use of network resources under the assumption that the number of slots is not used at the same time.However, the subscriber access rate may continuously exceed the predefined collection rate compared to the provisioning collection rate provisioned at the initial installation of the device. In some cases, for some time, it is possible that some subscribers cannot be provided with the communication service, especially during times of high call volume. However, the operator managing the subscriber network cannot collect the historical information for the aggregation cost evaluation through the existing V5.2 interface BCC protocol, so it is difficult to know that this is happening. Accordingly, some subscribers connected to the subscriber network transmission device for a certain time may not be able to receive the service smoothly.

The present invention has been proposed to solve the above problems, and generates an alert to the operator when the historical information and the threshold value of the resource allocation rate are exceeded in relation to the aggregation rate of the interface link, so as to generate an alarm in the interface having a low resource allocation rate. A computer program that records and manages the subscriber network resource allocation history information using the bearer channel access protocol's audit procedure, which allows the link to be relocated to some subscribers connected to the alerted link, and a program for realizing the method. The purpose is to provide a recording medium that can be used.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary configuration diagram of a subscriber network accommodating a V5.2 interface to which the present invention is applied.

The V5.2 interface 104 can have up to 16 2048 Kbps links 105, and the operation of the switch 106 and subscriber network transmission device 102 that accommodates these links is the respective operating system 103, 107. In order to efficiently manage the resources of the distributed subscriber network transmission device, the overall subscriber network resource management is performed by the pressurizer network operator 108 of the exchange operating system under responsibility.

The subscriber 101 of the V5.2 interface consists of a subscriber of a landline and ISDN service.

2 is a functional structure diagram for network resource management using a bearer channel access (BCC) protocol to which the present invention is applied.

The bearer channel access (BCC) protocol entity 202, 204 is a procedure for allocating a bearer channel or releasing an assigned bearer channel to a subscriber 101 connected to a subscriber network. Basically, there is a procedure for checking a path related to a connection, and performs an AUDIT procedure for collecting subscriber network resource allocation information using the information element of FIG. 5. This AUDIT procedure is performed on the responsibility of the exchange resource management entity 201 to efficiently manage distributed subscriber network resources.

The V5.2 interface provides aggregation to allow multiple subscribers to share limited subscriber network resources, and each link must be configured at initial installation of the subscriber network transmitter and switch that accommodates the V5.2 interface to take advantage of this aggregation. It is performed through provisioning of a aggregation ratio indicating the ratio of the number of access subscribers and the number of bearer channels (time slots) available.

The present invention performs the AUDIT procedure using the information element proposed in the present invention among the V5.2 interface BCC protocol to allocate the network resource (time slot) allocation rate of the subscriber network transmission device to flexibly manage the provisioned aggregation cost. Collect and manage. If the subscriber access rate exceeds the resource allocation rate threshold, which indicates when a subscriber who cannot be provided with a service first occurs, an alert is generated to the subscriber network operator. This resource allocation threshold is provisioned by the subscriber network operator, and the alerted subscriber network operator can relocate some subscribers of the link that exceed the aggregation cost to a V5.2 interface link with a relatively low subscriber access rate. Perform the procedure. That is, in order to smoothly provide communication services to all subscribers connected to the subscriber network accommodating the V5.2 interface, the subscriber network operator provides the basis information necessary for flexible network resource allocation according to the utilization of the subscriber network resources. Obtain basic information necessary for evaluating existing collection costs in subscriber network and designing collection costs.

The procedure for managing resource allocation history information proposed by the present invention is as follows. First, when the subscriber network operator 108 provisions the aggregation cost of each link of the V5.2 interface through the switch operating system 107, the resource allocation threshold and the network indicating the time when a subscriber who cannot be provided for the first time may occur. Enter the resource allocation rate measurement time interval as well.

The subscriber network operator 108 must input the same aggregation rate as the exchange through the subscriber network transmission device operating system 103. For efficient network resource management of a subscriber network transmission device having a distributed structure that is distributed to various regions through a V5.2 interface to one exchange, it is performed by a subscriber network operator through an exchange operation system. Accordingly, resource management of the entire subscriber network of the V5.2 interface is handled by the exchange resource management entity 201.

The exchange resource management entity 201 receives a threshold value of each link from the exchange operating system 107, a resource allocation threshold, and a measurement time interval, and then sends a threshold value of each link to the exchange operating system. The MDU_BCC_LE primitive 206 is sent to the bearer channel connection (BCC) protocol entity 202 using the V5.2 interface E1 link identifier and the measurement time interval as parameters.

Then, the bearer channel access (BCC) protocol entity 202 receiving it configures the information element of FIG. 5 using the received parameters, but puts a meaningless value in the "total timeslot allocation number" 505. Configure an AUDIT message of 4a and send it to the bearer channel access (BCC) protocol entity 204 of the subscriber network transmission device.

The bearer channel access (BCC) protocol entity 204 that received the AUDIT message recognizes the time slot allocation rate information element in the message, and the " V5.2 2048 kbps link identifier " Time interval "504 is sent to the subscriber network resource management entity 203 using the MDU_BCC_AN primitive 207.

The subscriber network resource management entity 203 uses the measurement time interval received through the MDU_BCC_AN primitive 207 as a start and stop time input value of a timer for monitoring resource allocation. When started, the total number of timeslots allocated in the link is counted, and if the timer stops, it is determined that the measurement time interval has ended, and the subscriber network resource management entity 203 determines the MDU_BCC_AN primitive 207. Sends the corresponding link identifier, the total number of timeslots assigned and the measurement time interval to the bearer channel access (BCC) protocol entity 204.

After the bearer channel connection (BCC) protocol entity 204 configures the timeslot allocation rate information element using the received information, it creates an AUDIT COMPLETE message of FIG. 4B to exchange side bearer channel connection (BCC) protocol entity. Send to (202).

The exchange side bearer channel connection (BCC) protocol entity 202 interprets the message and uses the MDU_BCC_LE primitive 206 as the exchange resource management entity 201 to " V5.2 2048 kbps link identifier. "," Measurement time interval "," total time slot allocation ".

The exchange resource management entity 201 calculates a network resource allocation rate using the received contents as shown in Equation 1 below.

Network resource allocation rate (%) = {(total timeslots allocated to subscribers in V5.2 interface E1 link) / (total timeslots allocated to bearer channel in E1 link)} X {1 (sec) / t (sec)} X 100

Where t represents the measurement time interval.

The exchange resource management entity 201 compares the calculated network resource allocation rate with the resource allocation threshold and, if the network resource allocation rate exceeds the resource allocation threshold, passes through the exchange management system 107 to the subscriber network operator 108. It sends an alert and notifies the exchange operating system 107 of the allocation rate calculated for each link to generate historical information related to the allocation rate.

After the notification of the history information, the resource management entity 201 of the exchange sends an MDU_BCC-LE primitive to the bearer channel access (BCC) _protocol entity 202 again at a measurement time interval to perform an AUDIT procedure. And, the subscriber network operator during the service may change the network resource allocation rate history information generation period, that is, the measurement time interval.

When the subscriber network operator 108 receives an alert through the exchange operating system 107, if the content of the alert indicates that the resource allocation threshold is exceeded, the subscriber network operator 108 searches for and relocates some subscribers of the link with a low resource allocation rate. The vision procedure is performed and periodic resource allocation history information of each link can be provided.

3 is a flowchart illustrating a method for collecting and managing subscriber network resource allocation history information using an AUDIT procedure of a bearer channel access (BCC) protocol according to the present invention.

The subscriber network operator may be the same person as the operator of the exchange. The subscriber network first inputs the aggregation cost and resource allocation threshold of the subscriber network. Here, the aggregation cost and resource allocation threshold are changeable, and the aggregation cost and resource allocation threshold are sent to the resource management entity so that the exchange resource management entity can perform all functions related to the subscriber network resource.

When the subscriber network operator inputs a resource allocation checking command, which takes the identifier of the E1 link and a network resource allocation rate measurement time interval as a parameter, through the exchange operating system, the exchange operating system receiving the resource allocation checking command is transferred to the exchange resource management entity. In step 301, a resource allocation rate retrieval request is reported using the identifier of the E1 link and a network resource allocation rate measurement time interval as parameters.

After the exchange resource management entity configures an MDU_BCC_LE primitive for an AUDIT request by adding a network resource allocation measurement time as a parameter to an existing parameter for a resource allocation retrieval request, the exchange side Transmit to bearer channel connection (BCC) protocol entity (302).

The exchange side bearer channel access (BCC) protocol entity receives an MDU_BCC_LE primitive for an AUDIT request, and then retrieves the content of the parameter to request resource allocation retrieval if there is a resource allocation rate measurement time. In step 303, the information element of FIG.

Then, an AUDIT message including the configured information element is sent to the subscriber network side bearer channel access (BCC) protocol entity (303).

After receiving the AUDIT message, if the BCC protocol entity determines that the message is normal after the protocol error check, the BCC protocol entity for the AUDIT request for the resource allocation rate retrieval request After configuring the MDU_BCC_AN primitive and transmits to the subscriber network resource management entity (304).

After receiving the MDU_BCC_AN primitive, the subscriber network resource management entity starts monitoring the total time slot allocations based on the measurement time interval for the link. At the end of the measurement time, an AUDITresponse MDU_BCC_AN primitive is sent to the subscriber network bearer channel access (BCC) protocol entity, which parameters the total number of timeslot allocations and measurement time intervals of the link. (305).

After receiving the AUDIT response MDU_BCC_AN Prompt, the subscriber network bearer channel access (BCC) protocol entity configures the information element of FIG. 4 and constructs an AUDIT COMPLETE message. And sends it to the exchange side bearer channel connection (BCC) protocol entity (306).

The exchange side bearer channel access (BCC) protocol entity receives an AUDIT COMPLETE message, recognizes that the message has performed a resource allocation rate check through the information element content, and then sends an AUDIT response. The L (MDU_BCC_LE) primitive constructs and sends it to the exchange side resource management entity (307).

The exchange resource management entity receives the MDU_BCC_LE primitive and then calculates the resource allocation rate using Equation 1 above (308), and if the monitored resource allocation rate exceeds the resource allocation threshold. Inspect (309).

As a result of the check, if the resource allocation rate exceeds the resource allocation threshold, the switching management system alerts the operator 310, notifies the operator of the resource allocation rate, and generates historical information about the resource allocation rate (311). .

As a result of the check, if the resource allocation rate does not exceed the resource allocation threshold, the switching management system notifies the operator of the resource allocation rate, and generates history information on the resource allocation rate (311).

4A and 4B are diagrams illustrating an example of a message format used in an AUDIT procedure of a bearer channel access (BCC) protocol used in the present invention, and illustrates an AUDIT of a bearer channel access (BCC) protocol. Indicates the format of the message used to collect time slot allocation rate related information during the procedure.

A time slot allocation rate information element (FIG. 5) is optionally attached to each message of the AUDIT (FIG. 4A) and AUDIT COMPLETE (FIG. 4B) message formats. Therefore, the implementation is simple because it uses the format of the existing message.

In other words, AUDIT and AUDIT COMPLETE messages consist of information elements such as protocol identifier, bearer channel access (BCC) reference number value, message type, and time slot allocation rate.

FIG. 5 is an exemplary diagram illustrating an information element for collecting time slot allocation rate information used in the present invention, and is a bearer channel access (BCC) for collecting time slot allocation rate information of an E1 link of a V5.2 interface. Represents an information element included in a message related to a protocol audit (AUDIT) procedure. That is, the time slot allocation rate information element of FIGS. 4A and 4B consists of an information element identifier, an information element length, a link identifier, a measurement time interval, and a total time slot allocation number.

The information element identifier 501 is a binary code uniquely identifying the information element and uses a code not used by existing information elements of a bearer channel access (BCC) protocol message.

The information element length 502 is the total number of bytes of the information element, and the length of the information element is 5 bytes.

V5.2 2048 Kbps (E1) Link Identifier 503 is an identifier of a link to collect allocation information. This value uses the value assigned to each E1 link in provisioning.

The measurement time interval 504 defines a time period for measuring the number of timeslot allocations of a corresponding link. The measurement time interval 504 is expressed in seconds and uses a binary notation.

The total timeslot allocation 505 is the total timeslot allocation measured by the subscriber network resource management entity, which uses binary numbers, the value in the AUDIT message is meaningless, only the AUDIT COMPLETE message. Only has meaning.

In summary, in order to manage the aggregation ratio of the V5.2 interface link providing the aggregation function, the AUDIT procedure of the BCC protocol is performed using the information element proposed in the present invention, and history information related to the network resource allocation ratio is obtained. Collect. At this time, if the network resource allocation rate exceeds the resource allocation rate threshold indicating the first occurrence of a subscriber who cannot receive the service, an alarm is generated to the subscriber network operator. .2 use the subscriber network resource allocation-related historical information provided by the present invention to relocate the links in the interface to some subscribers connected to the alerted link. Accordingly, the subscriber network operator can secure basic information for the evaluation of the design of the provisioned collection cost of the subscriber network and the design of the subscriber network later, and enable the flexible operation of the subscriber network resources.

The method of the present invention as described above may be implemented as a program and stored in a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.).

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited by the drawings.

The present invention as described above, in particular, in order to efficiently manage the distributed resources of the subscriber network to accommodate the V5.2 interface, the exchange side history information and threshold value of the resource allocation rate in relation to the aggregation cost of the V5.2 interface link to the operator By providing an alarm in the event of exceeding, the subscriber network operator can obtain the basic information for the evaluation of the design of the subscriber network's pre-provisioned collection costs and the design of the subscriber network later, and the flexible operation of subscriber network resources. There is an excellent effect that can be made possible.
