Detailed ways

In this embodiment, firstly, the network element device through which the service passes establishes a communication connection, and then sends a query command for related information to the network element device, obtains the service access code analysis result of the network element device, and calculates the next-hop network element The global unique identifier of the device, according to the global unique identifier, establishes a communication connection with the next-hop network element device, sends a query command for related information to the next-hop network element device, ..., and repeats the above steps until Find the landing network element of the service access code, so as to further obtain a complete voice topology of the switching network.

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

As shown in Figure 1, it is a flowchart of a method for establishing a communication connection in an embodiment of the present invention, and the specific steps are as follows:

Step 101. Establish a communication connection with the network element equipment that the service passes through, and send a query command to the network element equipment to obtain the call origination information or incoming call information of the network element equipment;

The above call origination information includes: conditional parameters required for subsequent query of routing information, such as call source name. The number of parameters and parameter names included in the call information may vary due to different equipment manufacturers. In this embodiment, the corresponding call initiation information can be obtained according to specific situations (for example, equipment from different manufacturers).

The above incoming information includes: condition parameters required for subsequent analysis, such as adjacent office number, trunk group name, call source name, number prefix set, number analysis selector, etc. The above parameters may vary with different adjacent network element devices. In this embodiment, the corresponding incoming information can be obtained according to specific situations.

Step 102, according to the calling information or incoming information, and the service access code of the service, by querying the call number analysis configuration, the service access code analysis result of the network element device is obtained, and the service access code analysis result includes the outbound route index;

The above service access code analysis results refer to condition parameter values required for subsequent calculations, such as outbound routing index, number conversion index, number type, and the like.

Step 103, extracting outbound routing information from the analysis result of the service access code according to the outbound routing index;

That is, according to the outbound route index obtained in step 102, the outbound route configuration of the system is queried, and the outbound route information and load sharing ratio are extracted from the service access code analysis results. The outbound route information is an index required for subsequent query of system data, and the load sharing ratio refers to the proportion of business allocated to each outbound route when there are multiple outbound routes.

Step 104. According to the outgoing routing information, query the outgoing routing configuration, and obtain the globally unique identifier of the next-hop network element device of the network element device;

The above outbound routing configuration includes globally unique identifiers of all adjacent network element devices. According to the outbound routing information obtained in step 103, the required identifiers can be extracted from the output results of the system through system query instructions.

The global unique identifier of the above network element equipment may be the No. 7 signaling point code of the network element equipment.

Step 105: Establish a communication connection with the next-hop network element device according to the globally unique identifier of the next-hop network element device, and then return to step 101;

The above steps 101-105 are repeated until the network element device of the service access code is found, so as to obtain the complete voice path topology of the switching network.

In this embodiment, in step 101, it can also be judged whether the network element device is the first hop network element device that initiates the service, and if the network element device is the first hop network element device, then the network element device The device sends a query command to obtain the call origination information or incoming call information of the network element device;

If the network element device is not the first hop network element device, the incoming information of the network element device is obtained according to the information of the previous hop network element device of the network element device, and then step 102 is executed.

The above-mentioned first-hop network element device is the network element device that initiates the service, that is, the network location where the service is initiated, and can be determined by the user of the switching network system.

Because in some cases, for some special business analysis, multiple trunk groups (that is, grouping) are set up between the same adjacent offices, and the services on these different trunk groups may be handled differently after entering the office, so The configured incoming information will be different, so you can also judge whether the selected incoming information is accurate.

In this embodiment, when it is determined that the network element device is not the first hop network element device, it may be further determined in step 101 whether there are multiple incoming trunk groups, and if there are multiple incoming trunk groups, and the When the incoming information of the two incoming trunk groups is consistent, then obtain the incoming information of the network element device;

If there are multiple incoming trunk groups, and the incoming information of multiple incoming trunk groups is inconsistent, the incoming information can be reselected according to the circuit identification code (CIC) of the last hop network element device of the network element device, and then perform the steps 102;

In this embodiment, before step 103 is executed, it can be judged whether the analysis result of the service access code is the landing number of the local office (the step of judging whether it is the landing number of the local office), if so, the network element device is the telephone line of the switching network The end point of the topology; if not, step 103 can be performed;

Of course, before performing the above step of judging whether it is the landing number of the local office, it is also possible to judge whether the service access code analysis result needs to be changed. Index, by checking the number conversion configuration, perform number conversion on the analysis result of the service access code, and then perform step 103.

If it is not necessary to change the number, then perform the step of judging whether it is the landing number of the local office.

It can be known from the above technical solution that firstly, the network element equipment that the business passes through establishes a communication connection, and according to different equipment manufacturers, send relevant information query instructions to the network element equipment, obtain the output information of the network element equipment, and calculate the next hop network element The global unique identifier of the device, according to the global unique identifier, establishes a communication connection with the next-hop network element device, and sends a query command for relevant information to the next-hop network element device... Repeat the above steps until the service is found The landing network element of the access code can calculate a complete switching network topology. Since the global unique identifier of the network element device is used in the process of calculating the switching network topology, it can effectively shield the equipment of different manufacturers. The difference between them improves the versatility of computing the topology of the switched network.

Referring to FIG. 2 , this figure shows a schematic diagram of a method for automatically calculating the topology of a switching network. Before performing the following steps, you can predetermine the service access code to be calculated and the specific network location where the service is initiated. After establishing a communication connection with the network element device that initiated the service, follow the steps below to perform corresponding query operations and calculation operations ,Specific steps are as follows:

Step 201, determine whether the network element device to be queried is the first hop network element device that initiates the service, if so, perform step 202; otherwise, perform step 203;

The above-mentioned first-hop network element device, that is, the initial network element device of the service, that is, the network location where the service is initiated, can be preset by the switching network system user.

Step 202: If it is the first hop network element device, query the system data configuration according to the predetermined network location (such as a certain wireless cell) where the service is initiated, and obtain relevant call origination information.

That is, according to the wireless cell name or logo or code input by the user, the condition parameters (such as the name of the call source) required for subsequent analysis are obtained by querying the data configuration of the system. Since the specific system parameters used by different equipment manufacturers are different , so the specific configuration to be queried is also different.

The above call origination information includes: conditional parameters required for subsequent query of routing information, such as the name of the call source, and the number and names of the above parameters will vary due to different device manufacturers.

Step 203, if it is not the first hop network element device, query system data according to the information of the previous hop network element device, and obtain relevant incoming information.

That is, according to the globally unique identifier of the previous hop network element device (such as the No. 7 signaling point code), and the connection information (such as the circuit identification code CIC) with the current hop network element device, etc., the system data is queried to obtain Condition parameter values (incoming information) required for subsequent analysis.

The above system data refers to the data required for the connection between adjacent offices, such as office direction data, trunk group data, sub-routing data, call source data, etc. Since the system data structures of different equipment manufacturers are different, the required The configuration data for queries is also different. In this embodiment, the system data can be preset according to specific conditions.

The above incoming information includes conditional parameter values required for subsequent analysis, such as: adjacent office number, trunk group name, call source name, number prefix set, number analysis selector, etc. The above parameter values will vary depending on different adjacent network It is different depending on the meta-device. In this embodiment, the corresponding incoming information can be selected according to the specific situation.

Step 204, if there are multiple incoming trunk groups, compare whether the incoming information is consistent, if consistent, execute step 206, if not, execute step 205;

Because in some cases, for some special business analysis, multiple trunk groups (that is, grouping) are set up between the same adjacent offices, and the services on these different trunk groups may be handled differently after entering the office, so The configured incoming information will be different.

Step 205 , if the incoming information of multiple trunk groups is inconsistent, it may be determined which trunk group's incoming information should be selected according to the outgoing route identification code selected by the last hop network element device.

In traditional circuit transmission, a circuit device between adjacent offices can be uniquely pointed out according to the circuit identification code. That is, the range of CIC values is compared to determine the call source of the desired trunk group.

Step 206, according to the calling information or incoming information, and the service access code, query the system data, obtain the service number analysis result, and then perform step 207;

In this step, the system data to be queried is mainly the call number analysis configuration, that is, the system will output the query result by querying the call number analysis configuration command, and the query result output from the system according to the call origination information or incoming call information obtained in the above steps Extract the business number analysis results required for subsequent calculations.

The analysis result of the above business number refers to the conditional parameters required for subsequent calculations, such as outbound routing index, number conversion index, number type, etc.

Step 207, judging whether the service number analysis result needs to be changed, if it needs to be changed, then execute step 208; otherwise, execute step 210;

The business number analysis result acquired in step 206 includes an indication of whether number conversion is required.

Step 208, if number change is required, query the number change configuration, and perform number change, and then perform step 209;

According to the number change index in the business number analysis result obtained in step 206, the number change configuration is checked through the system query command, and the change is performed according to the output result of the system.

Step 209, according to the number conversion configuration, determine whether the number analysis needs to be performed again after the number conversion, if yes, return to step 206; otherwise, execute step 211;

In the output result of the system in step 208, it will be displayed whether the number analysis needs to be carried out again, if it is displayed that the number analysis needs to be carried out again, then after step 209 is judged, return to step 206; otherwise, execute step 211.

Step 210, if it is not necessary to change the number, then judge whether the service number analysis result is the landing number of this office, if yes, then end this process; if not, then execute step 211;

The above landing number of the local office refers to the number sent from the core network by the network element device, which means that the network element device is the end point of the calculated switching network topology.

Step 211, if it is not the landing number of the local office, then continue the outbound route configuration, obtain the outbound route and the load sharing ratio, and then perform step 212;

According to the outbound route index obtained in step 206, the outbound route information and the load sharing ratio are extracted from the output result of the system through the system query command.

The above outbound route refers to an index required for subsequent query of system data. The above load sharing ratio refers to the ratio of services allocated to each outgoing route when there are multiple outgoing routes.

In this embodiment, serial query can be performed on hop-by-hop network element devices in the topology, and parallel query can be performed on multiple load-sharing network element devices in the same hop in the topology.

Step 212, according to the outbound routing information, continue to query the outbound routing configuration or office direction configuration, obtain the global unique identifier of the next-hop network element device (such as signaling point No. 7), and then perform step 213;

The global unique identifiers of all adjacent network element devices are included in the office route configuration or office direction configuration. According to the outbound route obtained in step 211, the required next-hop network is extracted from the output result of the system through the system query command. A globally unique identifier for the metadevice.

Step 213: Continue the configuration of the outgoing trunk group to obtain relevant outgoing information.

According to the outbound route obtained in step 211, the system query command is used to extract information such as the circuit identification code and other information required by the next-hop network element device in calculating the topology of the switched network from the output result of the system.

Steps 201 to 213 are repeated until the network element device corresponding to the local office landing number of the service number is found, that is, the network element device to which the service ultimately belongs. The landing network element device is the network element device corresponding to the landing number of the local office, that is, the end point of the calculated switching network topology.

In the embodiment of the present invention, the corresponding system data query operation can be performed according to the type of the device manufacturer being queried. The following three specific embodiments are introduced. Embodiment 1, Embodiment 2 and Embodiment 3 respectively list the examples of the manufacturers that are widely used at present——Huawei, Ericsson, and ZTE equipment.
