As a prior art, a user device queries a network device for a data model set identifier, and determines whether a data model set and an operation type set stored in the user device need to be updated according to the data model set identifier.

However, the user equipment can only determine that at least one of the stored data model set and the operation type set needs to be updated according to the data model set, and cannot determine whether the data model set needs to be updated or the operation type set needs to be updated.

The user equipment needs to acquire the instance data of the data model set from the network equipment under the condition that whether the data model set needs to be updated or the operation type set needs to be updated cannot be determined, whether all data model files included in the instance data of the data model set are stored locally is determined by analyzing the instance data of the data model set, whether the operation types supported by the locally-stored network equipment are consistent with the operation types determined through the instance data is determined, and finally the locally-stored data model set and/or the operation type set are determined to be updated.

Detailed Description

The technical solution in the present application will be described below with reference to the accompanying drawings.

Fig. 1 illustrates a simple network system 100, where the network system 100 includes at least a user equipment and a network device, each network device is configured with a data model set, the data model set includes at least one data model, and each data model set defines at least a part of operation types in an operation type set supported by the network device.

By way of example and not limitation, the network system 100 includes a user device 101, a network device 102, and a network device 103, where the user device 101 communicates with the network device 101 and the network device 102, respectively, the user device 101 creates, queries, modifies, or deletes data on the network device (e.g., the network device 102) based on a network configuration protocol Netconf, and when operating on data on the network device 102, the user device 101 needs to determine a set of data models configured on the network device 102 and a set of operation types supported by the network device 102, and access the network device 102 to the operation types supported by the network device 102.

A method for determining a set of data models configured on a network device and a set of operation types supported by the network device by a user equipment in the prior art is described below with reference to the network system 100 shown in fig. 1.

When the user equipment 101 accesses the network system 100, the user equipment 101 acquires a data model set, an operation type set, and a data model set identifier configured on the network equipment 102 from the network equipment 102, and stores the acquired data model set, operation type set, and data model set identifier locally. When the network device 102 needs to be accessed, the user equipment 101 determines the operation type supported by the network device 102 according to the data model set and the operation type set, and initiates access to the operation type supported by the network device 102.

When the data model set and/or the operation type set configured on the network device 102 change, the network device 102 may actively send an instance data middle set identifier of the changed data model set to the user device 101, or the user device 101 may also periodically obtain a data model set identifier corresponding to the network device 102 from the network device 102, and the user device 101 compares the locally stored data model set identifier with the data model set identifier from the network device 102:

if the two are the same, the user equipment 101 determines that the data model set configured on the network equipment 102 does not change, and the operation type supported by the network equipment 102 defined in each data model does not change, so that the user equipment 101 does not update the locally stored data model set and operation characteristic set;

if the two are different, the user equipment 101 determines that the set of data models configured on the network equipment 102 and/or the types of operations supported by the network equipment 102 defined in each data model have changed.

At this time, the user equipment 101 needs to obtain instance data of the data model set from the network device 102, compare the locally stored data model set with the data model set determined according to the instance data, determine whether all data models configured on the network device 102 are included in the locally stored data model set, and in the case that all data models configured on the network device 102 are not included locally, the user equipment 101 needs to obtain the locally non-stored data model from a specified storage address, that is, update the locally stored data model set.

Moreover, the user equipment 101 needs to compare the locally stored operation type set with the operation type set determined according to the instance data, determine whether the operation type supported by the network device 102 has changed, delete the operation type that is not supported by the locally stored network device 102, that is, update the locally stored operation type set.

It can be seen that, in the prior art, since the user equipment cannot determine whether the locally stored data model set needs to be updated or the locally stored operation type set needs to be updated according to the data model set identifier from the network device, the user equipment must analyze the instance data of the data model set acquired from the network device to determine whether the locally stored data model set and the locally stored operation type set need to be updated, respectively.

However, there is a case where only the locally stored set of data models needs to be updated, i.e. the locally stored set of operation types does not need to be updated, for the user equipment; alternatively, only the set of locally stored operation types need to be updated, i.e., the set of locally stored data models need not be updated.

In the prior art, for the above situation, since the user equipment cannot determine whether to update the locally stored data model set or the locally stored operation type set according to the data model set identification from the network device, the user equipment needs to determine whether to update the locally stored data model set and determine whether to update the locally stored operation type set according to the instance data of the data model set, thereby causing unnecessary system overhead in the case that only one of the sets needs to be updated.

Therefore, an embodiment of the present application provides an information indicating method, where first indication information and second indication information are respectively generated according to a reference file saved on a network device, where the first indication information is used by a user device to determine whether a locally stored data model set needs to be updated, and the second indication information is used by the user device to determine whether a locally stored operation type set needs to be updated, so that the user device can clearly determine which of the data model set and the operation type set needs to be updated, and thus, in a case where only one of the data model set needs to be updated, the user device only analyzes part of information in instance data of the data model set, thereby reducing unnecessary system overhead.

Fig. 2 is a schematic flow chart of a method 200 for information indication provided by an embodiment of the present application. The user equipment depicted in fig. 2 may be the user equipment 101 in fig. 1; the network device may be network device 102 or network device 103 of fig. 1. Of course, in an actual network system, the number of network devices may not be limited to the examples of the embodiment or other embodiments, and will not be described below.

By way of example and not limitation, the method is performed by user device 101 and network device 102 or network device 103. A first set of data models is configured on a network device, the first set of data models including at least one data model, each data model having at least some of a first set of operation types supported by the network device defined therein, the method 200 including at least the following steps.

Generating first indication information and second indication information according to a reference file, wherein the reference file is configured with relevant information of the first data model set and relevant information of the first operation type set, the first indication information is used for a user equipment to determine whether to update a second locally stored data model set, the second data model set is the same as at least part of data models included in the first data model set, and the second indication information is used for the user equipment to determine whether to update a second locally stored operation type set, the second operation type set is the same as at least part of operation types included in the first operation type set.

Specifically, the network device generates first indication information and second indication information according to a reference file saved locally and according to the reference file, where relevant information of a data model set (e.g., of a first data model set) configured on the network device and relevant information of an operation type set (e.g., of the first operation type set) supported by the network device defined in the first data model set are configured in the reference file.

By way of example and not limitation, the generating of the first indication information and the second indication information according to the reference file includes: determining relevant information of the first data model set from the reference file, and generating the first indication information according to the relevant information of the first data model set; and determining the related information of the first operation type set from the reference file, and generating the second indication information according to the related information of the first operation type set.

Specifically, before the network device generates the first indication information and the second indication information, the network device first needs to determine, from the reference file, the relevant information of the first data model set and the relevant information of the first operation type set, generate the first indication information according to the relevant information of the first data model set, and generate the second indication information according to the relevant information of the first operation type set.

By way of example and not limitation, the reference is instance data of the first set of data models configured on the network device.

In particular, the related information of the first set of data models may be information associated with data models in the first set of data models included in the instance data of the first set of data models, and the related information of the first set of operation types may be information associated with operation types in the first set of operation types included in the instance data of the first set of data models.

That is, the network device determines relevant information for the first set of data models from information associated with data models in the first set of data models included in the instance data for the first set of data models, and determines relevant information for the first set of operation types from information associated with operation types in the first set of operation types included in the instance data for the first set of data models.

By way of example and not limitation, the instance data of the first set of data models may include at least the following information:

a name (name) of each data model in the first set of data models, a name (name) of a sub-model of each data model, a namespace (namespace) and version (version) of each data model, a type of operation defined in each data model in the first set of data models, a type of operation defined in a sub-model of each data model, a type of correspondence-type of correspondence (deviation) of each data model and a consistency of each data model.

For example, the network device determines the name of each data model in the first set of data models, the name of the sub-model of each data model, the name space of each data model, and the version of each data model as the related information of the first set of data models.

For another example, the network device determines, as the related information of the first operation type set, the operation type defined in each data model in the first data model set, the operation type defined in the sub-model of each data model, and the type of consistency between the deviation of each data model and each data model.

It should be noted that, the above description is given by taking as an example that only the related information of the first data model set and the related information of the first operation type set include the above contents, but the embodiment of the present application is not limited to this, and the related information of the first data model set and the related information of the first operation type set may also include other contents in the example data of the first data model set, and the embodiment of the present application is not particularly limited to this.

A method for generating the first indication information according to the related information of the first data model set and generating the second indication information according to the related information of the first operation type set by the network device is described below.

Specifically, after the network device determines the relevant information of the first data model set, the network device generates first indication information according to the relevant information of the first data model set, and the first indication information is used for the user device to determine whether to update the locally stored data model set (for example, the second data model set).

By way of example and not limitation, the first indication information is generated by a Secure Hash Algorithm (SHA) using information associated with the first set of data models as input.

Specifically, after the network device determines the relevant information of the first operation type set, the network device generates second indication information according to the relevant information of the first operation type set, and the second indication information is used for the user device to determine whether to update the locally stored operation type set (for example, the second operation type set).

By way of example and not limitation, the second indication information is generated by a Secure Hash Algorithm (SHA) with information about the first set of operation types as input.

The deviation (deviation) of each data model is used for explaining the operation types which are not supported by the network equipment in the operation types defined in the data model; the consistency-type (consistency-type) of each data model is used to illustrate the difference between the data model and the data model specified by the standard.

In the embodiments of the present application, only the first instruction information and the second instruction information are generated by the above-described method, but the embodiments of the present application are not limited to this. For example, the related information of the first data model set and the related information of the first operation type set may be used as input, and the first indication information and the second indication information are generated by other algorithms, for example, a Cyclic Redundancy Check (CRC) algorithm.

202, sending the first indication information and the second indication information to the user equipment.

It should be noted that, in this embodiment of the application, the network device may actively generate the first indication information and the second indication information and send the first indication information and the second indication information to the user equipment when the data model in the first data model set changes and/or when the operation type in the operation type set (for example, the first operation type set) supported by the network device defined in the first data model set changes.

For example, when the data models in the first data model set configured on the network device are changed, for example, the number of data models in the first data model set configured on the network device increases.

At this time, the network device generates first indication information and sends the first indication information to the user device, wherein the first indication information is used for the user device to determine whether to update the second data model set stored locally.

When the user equipment determines that the locally stored second data model set needs to be updated, the user equipment first needs to obtain instance data of the changed first data model set from the network equipment, compare the locally stored second data model set with the data model set determined according to the instance data, determine whether all data models in the changed first data model set are contained in the locally stored second data model set, and when all data models in the changed first data model set are not locally stored, the user equipment needs to obtain the locally non-stored data model from a specified storage address and additionally store the obtained locally non-stored data model to the local, that is, update the locally stored second data model set.

For another example, when the operation type in the first operation type set supported by the network device defined in the first data model set configured on the network device changes, for example, a part of the operation types in the first operation type set originally supported by the network device is defined as an operation type not supported by the network device.

At this time, the network device generates second indication information and sends the second indication information to the user device, where the second indication information is used for the user device to determine whether to update the locally stored second operation type set, so that the user device updates the locally stored second operation type set according to the second indication information.

When the user equipment determines that the locally stored second operation type set needs to be updated, the user equipment needs to compare the locally stored second operation type set with an operation type set determined according to the changed instance data of the first data model set from the network device, and delete an operation type that is not supported by the network device in the locally stored second operation type set of the user equipment, that is, update the locally stored operation type set.

In addition, the network device may further be configured to, in a case where an inquiry message is received from the user device, request the network device to send the first indication information and the second indication information to the user device, generate, according to the inquiry instruction, the first indication information and the second indication information, and send the first indication information and the second indication information to the user device, so that the user device determines whether to update the second locally stored data model set according to the first indication information, and determine whether to update the second locally stored operation type set according to the second indication information.

And 203, receiving the first indication information and the second indication information sent by the network equipment.

204, according to the first indication information, determining whether to update a second locally stored set of data models, the second set of data models being of the same type as at least a portion of the data models included in the first set of data models.

And 205, determining whether to update a second set of operation types stored locally according to the second indication information, wherein the second set of operation types is the same as at least part of operation types included in the first set of operation types.

Specifically, in steps 203 to 205, the user equipment receives first indication information sent by the network equipment, and determines whether to update the second locally stored data model set according to the first indication information; and/or

In steps 203 to 205, the ue receives second indication information sent by the network device, and determines whether to update the locally stored second operation type set according to the second indication information.

Several cases in which the user equipment in the embodiment of the present application determines whether to update the second data model set and/or the second operation type set stored locally according to the first indication information and/or the second indication information are described below.

By way of example and not limitation, the user equipment locally stores third indication information, and in the case that the first indication information and the third indication information stored by the user equipment have the same content, the second data model set stored locally is determined not to be updated; or determining to update the second locally stored data model set in case the first indication information is different from the content of the third indication information stored by the user equipment.

By way of example and not limitation, the user equipment locally stores fourth indication information, and in the case that the second indication information is the same as the content of the fourth indication information stored by the user equipment, the second operation type set stored locally is determined not to be updated; or determining to update the locally stored second set of operation types in case the second indication information differs from the content of the fourth indication information stored by the user equipment.

Case 1

The first indication information is different from the third indication information stored by the user equipment in content, and the second indication information is the same as the fourth indication information stored by the user equipment in content.

Specifically, the user equipment receives first indication information sent by the network equipment, compares the first indication information with locally stored third indication information, determines that the content of the first indication information is different from that of the third indication information, receives second indication information sent by the network equipment, compares the second indication information with locally stored fourth indication information, and determines that the content of the second indication information is the same as that of the fourth indication information, and then the user equipment finally determines that the data model in the first data model set configured on the network equipment has changed, and determines that the operation type in the operation type set supported by the network equipment, which is defined in the changed first data model set configured on the network equipment, has not changed.

At this time, the user equipment acquires the instance data of the changed first data model set from the network equipment, determines the data model specifically included in the changed first data model set according to the instance data of the changed first data model set, updates the locally stored second data model set, and replaces the locally stored third indication information with the first indication information.

For example, the user equipment additionally stores the newly added data model in the changed first data model set into the second data model set.

At this time, the user equipment does not need to determine the operation types supported by the network equipment defined in the changed first data model set according to the instance data of the changed first data model set, that is, does not need to update the locally stored second operation type set.

Case 2

The first indication information and the third indication information stored by the user equipment have the same content, and the second indication information and the fourth indication information stored by the user equipment have different content.

Specifically, the user equipment receives first indication information sent by the network equipment, compares the first indication information with locally stored third indication information, determines that the content of the first indication information is the same as that of the third indication information, receives second indication information sent by the network equipment, compares the second indication information with locally stored fourth indication information, and determines that the content of the second indication information is different from that of the fourth indication information, and then the user equipment finally determines that the operation types in the first operation type set defined in the changed first data model set configured on the network equipment have changed, and determines that the data models in the changed first data model set have not changed.

At this time, the user equipment acquires the instance data of the changed first data model set from the network equipment, determines the operation types supported by the network equipment and defined in the changed first data model set according to the instance data of the changed first data model set, updates the locally stored second operation type set, and replaces the locally stored fourth indication information with the second indication information.

For example, the user equipment additionally stores the new operation type defined in the changed first data model set into the second operation type set, or the user equipment deletes the operation type defined in the changed first data model set as the operation type that is not supported by the network equipment from the second operation type set.

At this time, the user equipment does not need to determine the data model specifically included in the changed first data model set according to the instance data of the changed first data model set, that is, does not need to update the locally stored second data model set.

Case 3

The first indication information is different from the third indication information stored by the user equipment in content, and the second indication information is different from the fourth indication information stored by the user equipment in content.

Specifically, the user equipment receives first indication information sent by the network equipment, compares the first indication information with locally stored third indication information, determines that the content of the first indication information is different from that of the third indication information, receives second indication information sent by the network equipment, compares the second indication information with locally stored fourth indication information, and determines that the content of the second indication information is also different from that of the fourth indication information, and then the user equipment finally determines that the data model in the first data model set configured on the network equipment has changed, and determines that the operation type in the operation type set supported by the network equipment, which is defined in the changed first data model set configured on the network equipment, has also changed.

At this time, the user equipment obtains the instance data of the changed first data model set from the network equipment, and not only needs to determine the data model specifically included in the changed first data model set according to the instance data of the changed first data model set, but also needs to update the locally stored second data model set, and at the same time, replaces the locally stored third indication information with the first indication information.

For example, the new data model in the changed first data model set is additionally stored in the second data model set.

Moreover, it is further required to determine, according to the instance data of the changed first data model set, an operation type supported by the network device defined in the changed first data model set, update the locally stored second operation type set, and replace the locally stored fourth indication information with the second indication information.

By way of example and not limitation, the first indication information and the second indication information are carried in a character string comprising N characters, N ≧ 2, N is a positive integer.

By way of example and not limitation, the first indication information is carried in the first M consecutive characters of the N characters, the second indication information is carried in the N-M consecutive characters after the M characters of the N characters, M < N, M is a positive integer.

Specifically, for example, the information related to the first data model set is used as an input, information with a length of 160bits (bit) is generated by a secure hash algorithm, the network device represents the information with the length of 160bits in hexadecimal, that is, a character is generated for every 4 bits in the information with the length of 160bits, and finally, information including 40 characters is obtained, and the information is used as the first indication information.

The method comprises the steps that relevant information of a first operation type set is used as input, information with the length of 160bits (bits) is generated through a secure hash algorithm, the information with the length of 160bits is expressed in hexadecimal by network equipment, namely, every 4 bits in the information with the length of 160bits are generated into a character, and finally information comprising 40 characters is obtained and is used as second indication information.

And the network equipment sends a character string carrying the first indication information and the second indication information to the user equipment, wherein the character string comprises 80 characters.

By way of example and not limitation, the first 40 consecutive characters of the 80 characters are used to represent the first indication information and the second 40 consecutive characters of the 80 characters are used to indicate the second information character.

The user equipment receives the character string from the network equipment, compares the first 40 consecutive characters in the character string with the third character stored locally: if the two are the same, the second data model set stored locally is not updated; and if the two are different, determining to update the second data model set stored locally.

And comparing the last 40 consecutive characters in the string with locally stored fourth indication information: if the two are the same, not updating the second operation type set of the local storage; if the two are different, determining to update the second set of operation types stored locally.

The first indication information and the second indication information generated by the secure hash algorithm are generated by the secure hash algorithm, so that it can be ensured that the first indication information or the second indication information generated by the secure hash algorithm is the same for the same input, that is, for different network devices, if the first indication information generated by the secure hash algorithm is the same, it indicates that the first data model sets of the two are the same, and if the second indication information generated by the secure hash algorithm is the same, it indicates that the first operation type sets of the two are the same.
