With the development of the mobile internet, in order to meet the demand of traffic growth in the network, an IP (IP Radio Access Network, abbreviated as IPRAN) network of a radio access network based on an elastic pipe becomes a main local transport network. For the IPRAN network, not only the access loop but also the topology of the network needs to be satisfied. When the IPRAN network does not meet the topology structure of the network, interruption of related services or influence on the communication quality of users can be caused. Therefore, the topology standardization rate of the IPRAN network is an important index for evaluating the security of the IPRAN network.

In an exemplary embodiment, when determining the topology structure in the IPRAN network, network information of the IPRAN network may be obtained from a professional network management server through a northbound interface, where the network information includes network element information of each network element in the network and fiber connection information of each network element. The network element information includes information such as a branch company where each network element is located, a device model of the network element, a network element name, and the like.

102. And determining a network relation according to the network element information and the network element fiber connection information, wherein the network relation characterizes the topological relation among all network elements forming the IP network of the wireless access network.

For example, after acquiring the network element information and the connection information of each network element, a network relationship between the network elements, that is, a connection topology relationship between the network elements may be determined.

In one example, the network relationship may be determined sequentially according to the network element name relationship of each network element and the connection relationship between each network element and the rest of the network elements in the connection relationship of each network element, that is, one network element may be determined randomly, another network element connected with the network element may be found in the connection relationship of the network element, the network element name of another network element connected with another network element may be determined according to the connection relationship of another network element, and so on until all network elements of a ring network are found, and then the next ring network is found until all ring networks are found, thereby obtaining the topology relationship between all network elements in the IPRAN network, that is, the network relationship of the IPRAN network.

103. And determining topology error information on the network relation according to the network relation.

After the network relationship in the IPRAN network is found, it may be sequentially determined whether the topology relationship between the network elements meets the preset topology standard of the IPRAN network, that is, whether the number of network elements in each ring network or the network element connection identified in step 102 meets the preset topology standard of the IPRAN network is sequentially identified, and the network elements with the number of network elements or the connection not meeting the standard are selected from the network elements, so as to determine topology error information on the network relationship.

104. Generating and sending early warning information according to the topology error information, wherein the early warning information is used for prompting the occurrence of the topology error on the network relation.

After determining the topology error information on the network relationship, the method sends early warning to related personnel in time through network equipment, characterizes that the topology information error exists in the current IPRAN network, and reminds the related personnel of correcting the topology information error in time.

Fig. 2 is a flow chart of another early warning method applied to an IP network of a radio access network according to an embodiment of the present application. As shown in fig. 2, the method includes:

201. network information on an IP network of the wireless access network is obtained, wherein the network information characterizes network element information and network element fiber connection information of network elements on the IP network of the wireless access network.

Illustratively, this step may refer to step 101 in fig. 1, and will not be described in detail.

202. The network relation comprises a position identifier and a ring network number identifier of each network element, and the position identifier and the ring network number identifier of each network element are determined according to the network element information and the network element fiber connection information; wherein the location identifier characterizes a network hierarchy class of the network element; the ring network number identification characterizes that the network element belongs to a core ring, a convergence ring or an access ring.

In one example, the location identification includes the following identification: the system comprises core equipment, extension equipment, convergence equipment, N-level convergence equipment, access equipment and M-level access equipment; wherein N, M is an integer of 1 or more; step 202 specifically includes the following steps:

the first step, according to the network element information and the network element fiber connection information, determining the position mark in each network element as the network element of the core equipment, the expansion equipment, the convergence equipment, the N-level convergence equipment and the access equipment.

And a second step of determining the ring network number identification of each network element according to the network element information, the network element fiber connection information and the network elements with the position identifications.

And thirdly, according to the network element information, the network element fiber connection information and the ring network number identification of each network element, if the position identification of the network element in the same access ring is determined to be the access equipment, the position identification of the network element in the access ring is determined to be changed into the secondary access equipment.

And a fourth step, if the second-level access equipment in one access ring belongs to another access ring and the convergence equipment or the N-level convergence equipment exists in the other access ring, the position mark in the other access ring is changed into the first-level access equipment by the access equipment.

The second step specifically comprises the following steps: according to the network element information, the network element fiber connection information and the network element with the position identification, determining a core ring, a convergence ring and an access ring in the IP network of the wireless access network; according to a preset dividing mode, ring network number identifiers are set for each network element in a core ring, a convergence ring and an access ring in the IP network of the wireless access network.

The preset dividing mode comprises the following contents: setting ring network number identification for network elements under the access ring in each core ring in sequence; setting ring network number identifiers for network elements of access rings under each convergence ring under the core ring according to the sequence of the convergence rings under the core ring; setting an access ring sequence for an access ring under the convergence ring according to the slot board card identifier and the slot board bayonet identifier of the convergence device in the convergence ring; and setting ring network number identifiers for network elements of each access ring under the convergence ring according to the sequence of the access rings under the convergence ring.

After obtaining the network element information and the fiber connection information of each network element, the network level of each network element and the ring network of each network element can be determined, the network level of each network element is used as the position identifier, and the ring network number identifier of each ring network is determined according to the position identifier of the network element in each ring network, wherein the ring network number identifier represents that the network element in the ring network belongs to a core ring, a convergence ring or an access ring.

In one example, the network level of each network element may be found sequentially according to the preset relationship between the network element name of each network element and the network level of the network element, the network level is used as the location identifier of each network element, then all ring networks in the IPRAN network may be found according to the fiber connection relationship of each network element, and the ring network number identifier of each ring network may be determined according to the network location identifier of the network element in the ring network.

In one example, determining the location identifier and the ring network number identifier of each network element according to the network element information and the network element linking information may further be performed according to the following steps.

Firstly, because the number of network elements belonging to core equipment, expansion equipment, convergence equipment and N-level convergence equipment in the IPRAN network is small, and the connection between the network elements is relatively fixed, the network elements belonging to the core equipment, the network elements belonging to the convergence equipment and the network elements belonging to the N-level convergence equipment can be sequentially searched according to the preset relation between the position identifiers and the network element names, then the position identifiers of the network elements which have the connection relation with the core equipment and the connection with the core network are set as expansion equipment, and the rest network elements without the position identifier are endowed with the position identifiers of the access equipment. Or determining the looped network where each core device, extension device, convergence device and N-level convergence device are respectively located according to the looped network information where the preset storage core device, extension device, convergence device and N-level convergence device are located, and then marking the rest looped networks as access loops.

In determining the ring network number identifier of each network element according to the network element information, the network element fiber connection information and the network element with the position identifier, in one possible implementation manner, when determining the ring network number identifier, firstly determining the network element included in each ring network in the IPRAN network according to the fiber connection relationship among the network elements, and then in each ring network, firstly determining whether the network element in the ring network contains the access device, and if so, determining the ring network as the access ring. And if the unrecognized looped network comprises convergence equipment or primary convergence equipment or secondary convergence equipment, the looped network is a convergence ring. And finally the rest looped netowrk is a core loop.

And setting ring network number identifiers for each core ring, each convergence ring and each access ring according to a preset dividing mode, wherein the preset dividing mode can be marked according to the sequence of the acquired network elements. For example, when the ring network number identifier is set for the network element in each core ring for the identified core ring, the ring network number identifier of the core ring 1 is firstly assigned to each network element in the core ring where the first identified core device is located, then another core ring where another core device without the ring network number identifier of the core ring is located is sequentially searched, the ring network number identifier of the core ring 2 is assigned to each network element in the core ring, and so on until all the core rings are assigned. And then, setting a convergence ring identifier for each network element in a convergence ring under the core ring according to the sequence from the small label to the large label of the core ring.

In one possible implementation manner, the preset dividing manner may further include the following: when the ring network number identification is given to the network element under the access ring, firstly, the label is started from the access ring under the core ring with the smaller core ring label according to the sequence from the smaller core ring network number to the larger core ring network number. For network elements in the access ring under the same core ring, the network elements in the access ring under each aggregation ring are sequentially endowed with the ring network number identification of the access ring according to the sequence of the aggregation rings. When ring network number identifiers are given to the access rings hung under the same convergence ring, the sequence of the access rings is set according to the sequence from small to large of the slot board card identifiers of the convergence equipment and the sequence from small to large of the slot board card identifiers of the same slot board card identifiers. If N levels of convergence devices exist in the access ring under the convergence ring, setting the sequence of the access ring according to the sequence from small N to large N. After the access ring sequence is acquired, a ring network number identifier is set for each network element in each access ring, for example, an access ring 1, an access ring 2, and the like.

After the ring network number identification is given to each network element, if the network elements in the same access ring, namely, the position identifications of all the network elements with the same access ring network number are all access devices, the position identifications of the network elements in the access ring are modified into secondary access devices.

Then, if the network element in the same access ring, i.e. the network element with the same access ring network number, when the position identifier is the second-level access device and the network element also has the ring network number identifier of another access ring, and in addition, the position identifiers in all the network elements with the ring network number identifiers of another access ring have convergence devices or N-level convergence devices, the position identifier of the access device of the network element still in another access ring in the ring network is changed into the first-level access device.

203. And determining topology error information on the network relation according to the network relation.

In one example, the network relationship includes a location identifier and a ring network number identifier of each network element; the location identity characterizes a network level class of the network element; the ring network number identification characterizes that the network element belongs to a core ring, a convergence ring or an access ring.

The topology error information includes one or more of the following: the core ring is in a non-mouth-shaped connection mode, the core ring is in a net-shaped connection mode, the core ring is in a cross-core interconnection connection mode, the converging ring is in a non-mouth-shaped connection mode, the converging ring is in a net-shaped connection mode, the two-stage converging super-large ring is in a connection mode of cross-stage converging interconnection, the access ring is in a connection mode of accessing the super-large ring, the access ring is in a connection mode of accessing the cross-converging, and the access ring is in a connection mode of accessing the single-unit.

For example, it is required to sequentially identify whether the number of network elements or the network element connection in each ring network meets the preset topology standard of the IPRAN network, and select the network elements whose number or connection does not meet the standard, so as to determine topology error information on the network relationship. The topology error information comprises errors of a core ring, errors of a convergence ring and errors of an access ring. Error of a core ring, comprising: the core ring is in a non-square connection mode, the core ring is in a net-shaped connection mode, and the core ring is in a cross-core interconnection connection mode. Aggregating errors of a ring, comprising: the converging ring is in a non-mouth-shaped connection mode, the converging ring is in a net-shaped connection mode, the two-stage converging super-large ring is in a connection mode of crossing primary converging interconnection. An error of an access ring, comprising: the access ring is a connection mode of accessing the ultra-large ring, the access ring is a connection mode of accessing the cross-aggregation, and the access ring is a connection mode of accessing the single-unit.

Step 203 may include the following:

the first case. If the topology error information includes that the core ring is in a non-mouth-shaped connection mode, the core ring is in a net-shaped connection mode, and the core ring is in a cross-core interconnection connection mode, step 203 includes:

For each core ring, determining a first number of core devices and a second number of convergence devices in network elements with the same ring network number identification according to the network elements with the same ring network number identification; if the first number or the second number is not the first preset value, determining that the core ring is in a non-Chinese character 'kou' type connection mode.

For each core ring, if it is determined that at least one core device is connected with two expansion devices or at least one expansion device is connected with two core devices according to the position identifier and the ring network number identifier of each network element under the core ring, determining that the core ring is in a netlike connection mode.

For example, for network elements in a core ring, that is, for network elements with the same network number identifier of the core ring, if the first number of network elements with the location identifier of the core device in the core ring or the second number of network elements with the location identifier of the extension device in the core ring is not equal to the first preset value, the connection manner that the connection relationship between the core device and the extension device in the core ring is in a non-mouth shape is indicated, where the first preset value is 2.

In the same core ring with the same ring network number identification, if one core device is found to be connected with two expansion devices through the fiber connection relation of the core device or one expansion device is found to be connected with two network elements with the core device position identification through searching the fiber connection relation of the expansion device, the core device or the expansion device in the core ring is determined to be in a net-shaped connection mode.

In the same core ring with the same ring network number identification, if the network element connected with a certain expansion device comprises the network element with the expansion device and the ring network number identifications of the two expansion devices are different, the current core ring connection mode is a cross-core interconnection connection mode.

The second case. If the topology error information includes that the aggregation ring is in a non-mouth-shaped connection mode, the aggregation ring is in a net-shaped connection mode, the connection mode of the second-level aggregation super-large ring, and the aggregation ring is in a connection mode of cross-level aggregation interconnection, step 203 includes:

for each convergence ring under the core ring, determining a third number of convergence devices under the convergence ring and a fourth number of first-level convergence devices under the convergence ring; if the third number or the fourth number is not the second preset value, the convergence ring is determined to be in a non-square connection mode.

For each convergence ring under the core ring, determining that at least one convergence device under the convergence ring is connected with two core devices or at least one primary convergence device under the convergence ring is connected with two core devices, and determining that the convergence ring is in a net-shaped connection mode.

For each convergence ring under the core ring, if the fifth number of the secondary convergence devices under the convergence ring is greater than or equal to a first threshold, determining that the convergence ring is a connection mode of the secondary convergence super-large ring.

For example, for network elements in the aggregation ring with the same ring network number identifier, if the third number of aggregation devices and the fourth number of primary aggregation devices are determined according to the position identifier of the network element in each aggregation, whether the third number or the fourth number is a second preset value is judged, if not, the connection mode of the aggregation ring is a non-square connection mode, wherein the second preset value is 2.

For network elements in the aggregation ring with the same ring network number identification, according to the position identification, the aggregation equipment, the core equipment and the primary aggregation equipment are found, whether a connection relation exists between one aggregation equipment and two core equipment or between one primary aggregation equipment and two core equipment is judged through the fiber connection relation of the network elements, and if the connection relation exists, the current connection mode of the aggregation ring is a net-shaped connection mode.

And counting the fifth number of network elements with the second-level aggregation equipment in the aggregation ring with the same ring network number identification according to the position identification, judging whether the fifth number is larger than or equal to a first threshold value, and if so, indicating that the connection mode of the current aggregation ring is the connection mode of the second-level aggregation super-large ring, wherein the first threshold value is 4.

And for network elements in the convergence ring with the same ring network number identification, determining the secondary convergence equipment and the core equipment according to the position identification, and if the connection relation between the identified secondary convergence equipment and the core equipment is found in the fiber connection relation, indicating that the connection mode of the current convergence ring is a connection mode of cross-primary convergence interconnection.

And a third case. If the topology error information includes a connection mode in which the access ring is an access oversized ring, a connection mode in which the access ring is an access cross-aggregation connection mode, and a connection mode in which the access ring is an access single-return connection mode, step 203 includes:

For example, for network elements in the access ring with the same ring network number identifier, determining the access device therein according to the position identifier of the network element, counting the sixth number of the access devices, and if the sixth number is greater than or equal to a second threshold, indicating that the connection mode of the current access ring is the connection mode of the access super-large ring, wherein the second threshold is 8.

For network elements in the access ring with the same ring network number identification, determining convergence equipment in the access ring according to the position identification, determining convergence equipment with the access ring network number identification and the convergence ring network number identification in the convergence equipment according to the ring network number identification of each convergence equipment, further counting the number of the convergence equipment with the access ring network number identification and the convergence ring network number identification, and if the number is larger than a third threshold, indicating that the current connection mode of the access ring is an access cross-convergence connection mode, wherein the third threshold is 2; if the number is equal to the third preset value, the current connection mode of the access ring is indicated to be the connection mode of the access list.

Illustratively, this step is referred to step 104 in fig. 1, and will not be described in detail.

205. Generating an error report according to the topology error information; wherein the error report includes the network error rate.

For example, after the topology error information is obtained, a correction report may be generated, where the correction report includes the network element name, the branch company where the network element is located, the ring network number identifier where the network element is located, and the topology error information of the network element. And counting the number of network elements in the topology error information in the IPRAN network and the number of all network elements in the IPRAN network, and taking the ratio of the network elements as the network error rate. And subtracting the network error rate from the preset value to obtain the topology standardization rate of the IPRAN network.

In the embodiment of the application, firstly, network element information and a fiber connection relation of network elements are acquired, and a position identifier and a ring network number identifier are assigned to each network element according to the acquired network element information and the fiber connection relation. In the process of assigning ring network number identifiers, ring network number identifiers are assigned to each ring network according to a preset sequence, and then topology error information in network element connection at the positions is quickly and orderly searched according to the assigned ring network number identifiers, position identifiers and fiber connection relations, so that early warning is generated, and related personnel are reminded of carrying out network maintenance and overhaul as soon as possible. In addition, when the topology error information is judged, the topology error information is divided for each error type, and the information such as each error type, network elements connected with errors and the like is timely generated into a correction report, so that relevant personnel can quickly know the error type of the network element connection after acquiring the report, and the error correction time is shortened.
