All the components in the network device running indicator implementation device of the embodiment of the present invention may be deployed in a physical entity, or may be deployed in combination on different physical entities as needed.

The following describes the process of implementing the network operation indicator in the embodiment of the present invention by taking the 2G acknowledgment traffic volume indicator of the cell 10 as an example:

1. Receive the input indicator input by the user, that is, the 2G utterance response traffic of the cell 10 and the calculation rule thereof, and the indicator and the metric calculation rule are input according to the format XML format provided by the GUI user interface GUI device 201.

The user requirement of the embodiment is the 2G utterance response traffic of the cell 10. Therefore, the calculation rule for the user to formulate the 2G utterance response traffic of the cell 10 includes: filtering rules of object information, filtering rules of service attributes, and filtering of measurement indicators. The rules for updating rules and measurement indicators are as follows:

The filtering rule of the object information is: the object information cell field value in the CDR is 10, and the cell field value is 10, and the filtering is performed; otherwise, no processing is required;

The filtering rule of the service attribute is: The primary and called side access types in the CDR are 2G access types, and the 2G access type is filtered, otherwise no processing is required;

The filtering rule of the measurement index is: The CONNECT message received by the called side in the CDR is set to 1. According to the sending and receiving of the key information of the call flow, the status of the current call can be judged, for example, the calling side receives the SET UP. Message, the current call is in the call state; the called party receives the ACM message. The current call is in the on state; the called party receives the CONNECT message, and the current call is in the answer state. Therefore, when the CONNECT message received by the called party is set to 1, the call has already been answered, so the response traffic is measured. The filtering rule of the indicator is that the CONNECT message received by the called side is set to 1; the update rule of the measurement indicator is: the call end time minus the called response time, for example, the call end time is 12:30, and the called response time is 10 :05 , the update rule of the measurement index is: 12:30 minus 10:05, the result is 2 hours and 25 minutes, because the calculation rule of the response traffic is the call end time minus the called response time, so the measurement index The update rule is "the call end time in the CDR minus the called response time in the CDR".

Second, analyze the received indicators and indicators calculation rules. According to the format of the index and the index calculation rule input by the user, the order of the rule calculation rule input by the user is not required, and the specific analysis process may be:

<MTName>AnswerTraffic</MTName> <! —Custom Calculation Index Name >

<PCDRFieldType>integer</PCDRFieldType>

</customMTs>

The receiving CDRs are sent by the network device 204. The network device that sends the CDRs has a plurality of network devices. The network devices output CDRs for each call. After the index calculation rules are parsed, the analysis results of the rules are calculated according to the indicators. The CDR is filtered, matched, and calculated.

In this embodiment, the index calculation process of the index calculation engine function unit 2032 is as follows:

1. Filtering of object information: Each CDR sent by the network device includes cell field information related to the call. If the cell field of the CDR is 10, the object information rule is satisfied, and the next rule is calculated by filtering, if If the CDR cell field information is invalid or the cell field information is not 10, the object information rule is not satisfied, and no processing is required;

2. Filtering of service attributes: The CDR sent by the network device includes the calling side access type field. Value, if the field value of the CDR of a call is 2G, the service attribute specification 'J is satisfied, and if the CDR of the call includes the value of the call side access type field of 3G, the service is not satisfied. Attribute rules, no need to deal with;

3. Filtering of measurement indicators: Determine whether the CONNECT flag received by the called side is 1 in the message bits in the CDR sent by the network device. If yes, it conforms to the measurement index rule, and performs the next rule operation by filtering. Otherwise, , does not meet the measurement index rules, no need to deal with;

4. Operation of the indicator update rule: After the operation of the above three filter rules is obtained, a set of CDRs conforming to the above rule is obtained, and according to the indicator update rule, that is, "call end time - called answer time", each set is taken out The call end time field and the called response time field of the CDR are calculated according to the indicator update rule (also referred to as the indicator update formula), and the value of the response traffic is calculated.

It should be noted that, in the operation process of the above indicator rules, the first three steps are not sequential.

4. Store the value of the received response traffic for analysis and use by the operator.

The following is also an example of the 2G call response traffic volume indicator of the cell 10, and the network operation indicator of the embodiment of the present invention is implemented to implement the system operation process:

1. The indicator custom graphical user interface GUI device 201 receives the 2G utterance response traffic volume of the indicator cell 10 input by the user and the calculation rule thereof, and the indicator and index calculation rule customizes the format provided by the graphical user interface GUI device 201 according to the indicator. The text format is entered and the rules are sent to the performance data server PDS 203.

The user requirement in this embodiment is that the 2G utterance of the cell 10 responds to the traffic, so the user formulates the cell.

The calculation rules of the 2G vocal response traffic include: the filtering rules of the object information, the filtering rules of the service attributes, the filtering rules of the measurement indicators, and the update rules of the measurement indicators, which are specifically:

The filtering rule of the object information is: the object information cell field value in the CDR is 10, and the cell field value is 10, and the filtering is performed; otherwise, no processing is required; The filtering rule of the service attribute is as follows: The service attribute on the primary and the called side of the CDR is the 2G access type, and the 2G access type is filtered. Otherwise, no processing is required.

The filtering rule of the measurement index is that the CONNECT message received by the called side in the CDR is set to 1, and the status of the current call is determined according to the sending and receiving of the key information of the call flow, for example, the calling side receives the SET UP message. The current call is in the call state; the called party receives the ACM message, the current call is in the on state; the called party receives the CONNECT message, and the current call is in the answer state. Therefore, when the called party receives the CONNECT message flag When the value is 1, the call has already been answered. Therefore, the filtering rule for measuring the response traffic indicator is that the CONNECT message received by the called side is 1; the update rule of the measurement indicator is: the call end time minus the called response time Since the calculation rule of the response traffic is the call end time minus the called response time, the update rule of the measurement indicator is "the call end time in the CDR minus the called response time in the CDR";

2. The index calculation rule parsing unit 2031 of the performance data server PDS 203 receives the index and the index calculation rule sent by the indicator custom graphical user interface GUI device 201, parses the index and the index calculation rule, and sends the parsed result to the index calculation engine. The function unit 2032 parses the received indicator and the indicator calculation rule. The parsing is performed according to the format of the index and the index calculation rule input by the user, and there is no requirement for the order of the index calculation rule input by the user. The specific parsing process may be:

<MTName>AnswerTraffic</MTName> <! —Custom Calculation Index Name >

<PCDRFieldType>integer</PCDRFieldType>

</property>

<property name="operator">equal to</property> <property name="value">l 0</property>

<property name="operator">minus</property>

<PCDRFieldType>integer</PCDRFieldType> </property>

</calculate>

</calculates>

</customMT>

</customMT>

</customMTs>;

3. The index calculation engine function unit 2032 receives the CDRs sent by the network device 204, and the network device 204 sends a plurality of network devices, and the network devices are lost for each call. The CDR is sent out to the index calculation engine function unit 2032. After receiving the analysis of the index calculation rule sent by the index calculation rule analysis unit 2031, the unit filters, matches, and calculates the CDR according to the analysis result of the index calculation rule.

In this embodiment, the index calculation process of the index calculation engine function unit 2032 is as follows: a) filtering of object information; each CDR sent by the network device includes cell field information related to the call, if the cell field of the CDR is 10 , the object information rule is satisfied, and if the CDR cell field information is invalid or the cell field information is not 10, the object information rule is not satisfied, and no processing is required;

b) Filtering of service attributes: The CDRs sent by the network device include the value of the calling side access type field. If the field value of the CDR of a call is 2G, the service attribute rule is met, and if a call is made, If the field value of the calling side access type field is 3G, the CDR does not satisfy the service attribute rule and does not need to be processed.

c) Filtering the measurement index: Determine whether the CONNECT flag received by the called party in the message bit sent by the network device is 1 or not. If yes, it complies with the measurement index rule and passes the filtering. Otherwise, the measurement index rule is not met. No need to deal with;

d) Operation of the indicator update rule: After the operation of the above three filter rules is obtained, a set of CDRs conforming to the above rule is obtained, and according to the indicator update rule, that is, "the call end time minus the called response time", the set is taken out The call end time field and the called response time field of each CDR are calculated according to an indicator update rule (also referred to as an indicator update formula), and the value of the response traffic is calculated.

4. The index calculation engine function unit 2032 transmits the value of the obtained response traffic to the indicator storage unit 2033.
