Description

Technical Field

[0001] The embodiments of the present invention relate to the field of communication network technology, and in particular to a message retrieval method, apparatus, electronic device and storage medium. Background Technology

[0002] With the continuous development of communication technology, staff often need to perform business analysis work using a large number of signaling messages generated between network elements. Therefore, Hadoop, a distributed file system used to store large amounts of signaling messages, plays an important role in this process.

[0003] In existing solutions, when conducting business analysis, customers first need to query relevant signaling message data using Hadoop, and then retrieve the corresponding signaling messages based on this data. However, Hadoop not only consumes a large amount of CPU and memory when storing signaling messages, but also affects the retrieval of signaling messages as the data space usage increases. This results in low efficiency in both storing and retrieving signaling messages, severely impacting the user experience. Summary of the Invention

[0004] This invention provides a message retrieval method, apparatus, electronic device, and storage medium. By introducing an index file, it not only solves the problem of large data space occupation caused by the large amount of signaling message data, but also improves the retrieval efficiency of signaling messages and the user experience.

[0005] In a first aspect, embodiments of the present invention provide a message retrieval method, the method comprising:

[0006] Based on the detected triggering operation, determine the target external data representation data;

[0007] When a message retrieval instruction is received, the target index file and the target message file to be retrieved are determined based on the timestamp corresponding to the target external data representation data.

[0008] Based on the data identifier corresponding to the target external data representation data, target index information is determined from the target index file, and at least one target signaling message is determined from the target message file to be retrieved based on the target index information.

[0009] Secondly, embodiments of the present invention also provide a message retrieval device, the device comprising:

[0010] The target external data representation determination module is used to determine the target external data representation data based on the detected triggering operation.

[0011] The target index file determination module is used to determine the target index file and the target message file to be retrieved based on the timestamp corresponding to the target external data representation data when a message retrieval instruction is received.

[0012] The target signaling message determination module is used to determine target index information from the target index file based on the data identifier corresponding to the target external data representation data, and to determine at least one target signaling message from the target message file to be retrieved based on the target index information.

[0013] Thirdly, embodiments of the present invention also provide an electronic device, the electronic device comprising:

[0014] one or more processors;

[0015] Storage device for storing one or more programs.

[0016] When the one or more programs are executed by the one or more processors, the one or more processors implement the message retrieval method as described in any of the embodiments of the present invention.

[0017] Fourthly, embodiments of the present invention also provide a storage medium containing computer-executable instructions, which, when executed by a computer processor, are used to perform the message retrieval method as described in any of the embodiments of the present invention.

[0018] The technical solution of this invention determines the target external data representation data, i.e., the XDR data to be analyzed, based on the detected trigger operation. When a message retrieval instruction is received, the target index file and the target message file to be retrieved are determined based on the timestamp corresponding to the target external data representation data. Furthermore, the target index information is determined from the target index file based on the data identifier corresponding to the target external data representation data, and at least one target signaling message is determined from the target message file to be retrieved based on the target index information. In the process of storing and retrieving signaling messages, by introducing an index file, not only is the problem of large data space occupation caused by the large amount of signaling message data solved, but it is also conducive to quickly locating the content of the signaling message, improving the retrieval efficiency of signaling messages and the user experience.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0026] Example 1

[0027] Figure 1 This is a flowchart illustrating a message retrieval method provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where a large number of signaling messages are stored and retrieved. The method can be executed by a message retrieval device, which can be implemented in the form of software and / or hardware. The hardware can be an electronic device, such as a mobile terminal, a PC, or a server.

[0028] like Figure 1 As shown, the method specifically includes the following steps:

[0029] S110. Based on the detected trigger operation, determine the target external data representation data.

[0030] In this embodiment, the system can detect user-triggered operations and determine whether a signaling message retrieval operation needs to be performed. For example, a signaling message retrieval control is pre-developed within the system. When the system detects that a user clicks on this control, the subsequent signaling message retrieval operation can be performed according to the scheme of this embodiment.

[0031] In this embodiment, signaling data packets generated by each network element device are first acquired according to a preset time interval. Then, a message file to be retrieved corresponding to each time period and at least one external data representation method are generated based on the signaling data packets. The signaling data packets contain a large number of signaling messages, which can be request and response messages associated with one or more sessions. For example, when the preset time interval is five seconds, the system needs to use the signaling acquisition module to acquire signaling data packets between network elements devices every five seconds in a splitting or mirroring manner. Of course, in practical applications, the system can also acquire signaling messages generated between network elements devices in real time; this will not be elaborated further in this embodiment.

[0032] Furthermore, the system can use the acquired signaling data packets as a data foundation to generate a message file to be retrieved and external data representation data. The message file to be retrieved is a file containing the specific content of request and response messages. The external data representation data is XDR (X Data Recording) data. Specifically, XDR evolved from Call Data Recording (CDR). It can be understood that CDR is a record of key network information during a call in traditional communication networks. Correspondingly, XDR, as an extension of the CDR concept, broadly refers to the record of key information about data traffic in mobile networks and bearer networks, i.e., traffic logs. When using user sessions as a unit, one session can form one XDR record. Furthermore, because the field format and number of fields in XDR documents are relatively uniform, the system can store the generated XDR documents in Hadoop to support various upper-layer applications. Specifically, when generating the aforementioned message files to be retrieved and external data representation data, signaling data packets can be parsed, and message files to be retrieved corresponding to each time period can be generated based on the parsed signaling messages; according to the session identifier carried by each signaling message, signaling messages belonging to the same session can be associated separately; target fields can be extracted from each signaling message, and multiple target fields can be integrated according to the association relationship between each signaling message to obtain at least one external data representation data.

[0033] For example, the system can pre-allocate a certain amount of storage space (e.g., 200MB) in the operating system's memory using the signaling message storage module, and then manage file handles according to a certain time granularity (e.g., 5 minutes). Based on this, after acquiring signaling data packets, the system can use the message decoding module to decode the signaling messages, determine each request message and response message, and then store these signaling messages in the storage space corresponding to the file handles within the aforementioned time period. Simultaneously, the system can use the message association module to associate request messages and response messages belonging to the same session, and extract the target fields from each associated message into the XDR document. For example, the determined device IP address, port number, serial number, and user location information can be extracted into the XDR document. Further, after assigning a unique identifier (XDR ID) to the XDR document, it can be sent to the document storage module for storage. It should be noted that the timestamp in the XDR document is obtained from the signaling message associated with generating the XDR document. It is also understood that the corresponding message file to be retrieved also carries the XDR ID and timestamp, which will not be described in detail in this embodiment.

[0034] In this embodiment, after generating the message file to be retrieved and at least one XDR data, the system also needs to establish a corresponding index file based on the timestamp and data length corresponding to the target external data representation data, and establish a message file corresponding to the index file based on at least one signaling message. When a message retrieval instruction is received, the system determines the target index file based on the retrieval time corresponding to the message retrieval instruction, and then retrieves at least one target signaling message from the corresponding message file based on the index information in the target index file. The index information includes the timestamp, data identifier, signaling data length, and the offset of the starting storage position of the signaling data within the corresponding storage space. This can be understood as follows: after storing the signaling message in the storage space corresponding to the file handle, the system can also confirm and record its data packet length and the offset of the starting storage position within that storage space. Furthermore, by combining the XDR ID and the timestamp, the index file can be generated. During the generation of the index file, the index file storage module can also first allocate a certain size of memory space (e.g., 200M) and write the aforementioned attribute information into that space. When the memory is full, the content is then written into the index file. This process can also be understood as constructing corresponding index information based on the timestamp and data length of at least one external data representation. It should be noted that when generating the index file, the system can also sort the index information according to the timestamp; and generate index files corresponding to each time period based on the sorted index information. The advantage of this approach is that in subsequent message retrieval processes, the index content in the index file can be quickly located using a fast search method.

[0035] In this embodiment, after the XDR document, the message file to be retrieved, and the index file are stored in the manner described above, when a specific signaling message is retrieved according to user needs, the system can determine the retrieval time information or retrieval identification information based on the detected trigger operation; and determine the target external data representation data from the data storage module based on the retrieval time information or retrieval identification information. For example, the system can determine the target XDR document to be analyzed in the XDR document database based on the retrieval time information input by the user through a web application, and then perform subsequent message retrieval operations based on the XDR ID and timestamp carried by the data.

[0036] S120. When a message retrieval instruction is received, the target index file and the target message file to be retrieved are determined based on the timestamp corresponding to the target external data representation data.

[0037] In this embodiment, when a message retrieval instruction is received, the system can determine the XDR ID and timestamp carried by the target XDR data. At the same time, it determines the target time period based on the timestamp corresponding to the target external data representation data. It then determines the target index file corresponding to the target time period from the storage space and the target message file to be retrieved corresponding to the target time period from the internal memory.

[0038] For example, once the timestamp carried by the target XDR data is determined, the time period it represents can be determined based on the timestamp. Further, the target index file is determined based on the retrieval time corresponding to the retrieval command, and then the message file corresponding to the index file is determined. It can be understood that once the above two types of files corresponding to the XDR document are determined, the subsequent message retrieval operation is also a drill-down analysis operation targeting the XDR document. Those skilled in the art should understand that this operation is an analysis operation in a data warehouse, that is, based on a specific XDR document, descending along a specific attribute dimension to obtain more detailed data. In this embodiment, through drill-down analysis of the target XDR document, the corresponding signaling messages can be displayed to staff in a visual form, thereby facilitating staff to solve specific problems or optimize the network based on the parsed signaling messages.

[0039] S130. Based on the data identifier corresponding to the target external data representation data, determine the target index information from the target index file, and determine at least one target signaling message from the target message file to be retrieved based on the target index information.

[0040] In this embodiment, after determining the target message file to be retrieved and the target index file based on the timestamp carried by the target XDR document, the target index file can be traversed according to the XDR ID of the target XDR document. Optionally, the target signaling data length and the target starting storage location offset are determined based on the target index information; based on the target signaling data length and the target starting storage location offset, the signaling data position is determined from the target message file to be retrieved, and the data at the signaling data position is decoded to obtain at least one target signaling message.

[0041] Specifically, after the web application sends a message retrieval request to the message retrieval module, the module determines the target index file based on the timestamp carried by the target XDR document. After loading this file into memory, the module can determine the corresponding data packet length and starting storage location offset within the index content based on the XDR ID of the target XDR document. Simultaneously, the target message file to be retrieved is loaded into memory, and the target signaling message can be located based on the determined data packet length and starting storage location offset. Finally, the message interpretation module can convert the signaling message content into a readable format and send it to the corresponding web client for user viewing.

[0042] The technical solution of this embodiment determines the target external data representation data, i.e., the XDR data to be analyzed, based on the detected trigger operation. When a message retrieval instruction is received, the target index file and the target message file to be retrieved are determined based on the timestamp corresponding to the target external data representation data. Furthermore, the target index information is determined from the target index file based on the data identifier corresponding to the target external data representation data, and at least one target signaling message is determined from the target message file to be retrieved based on the target index information. In the process of storing and retrieving signaling messages, by introducing an index file, not only is the problem of large data space occupation caused by the large amount of signaling message data solved, but it is also conducive to quickly locating the content of the signaling message, improving the retrieval efficiency of signaling messages and the user experience.

[0043] Example 2

[0044] As an optional embodiment of the above embodiments, Figure 2 This is a schematic diagram of the signaling message storage principle provided in Embodiment 2 of the present invention. Figure 3 This is a schematic diagram illustrating the signaling message retrieval principle provided in Embodiment 2 of the present invention. To clearly illustrate the technical solution of this embodiment, an example can be given of a scenario involving the storage and retrieval of a large number of signaling messages. However, this is not limited to the above scenario and can be applied to various scenarios requiring the retrieval of signaling messages generated between network elements.

[0045] See Figure 2 The signaling message storage process involves the system's data acquisition module, message decoding module, message association module, document storage module, database, signaling message output module, signaling message storage module, and index file storage module. The following section describes the signaling message storage process in conjunction with these modules.

[0046] See also Figure 2 The data acquisition module can collect signaling data packets generated between network elements via optical splitting or mirroring. The message decoding module decodes the collected signaling messages to obtain key fields. Furthermore, the message association module can associate request and response messages belonging to the same session based on the signaling identifiers within the signaling messages. It extracts key fields from the request and response messages into an XDR document, assigns a unique identifier (XDR ID) to this XDR document, and sends the XDR document to the document storage module. The request and response messages, tagged with the XDR ID, are then sent to the signaling message output module. To ensure consistency in the storage lifecycle of message files and index files, the signaling message output module is responsible for the unified management of signaling message storage and index file storage. To improve storage speed, the signaling message storage module first requests a certain amount of storage space, and then manages file handles according to a certain time granularity. After receiving a signaling message with an XDR ID and a timestamp from the message association module, the message storage module first locates the file handle of the time granularity based on the message's timestamp, stores the message in the storage space corresponding to the file handle, records the message and data packet length and the starting position offset of the storage space, and then sends the message's XDR ID, timestamp, data packet length, and position offset to the index file storage module.

[0047] See also Figure 2 Once the index file storage module receives the above information, it can store it in the corresponding index file. To improve storage speed, the index file storage module can also first allocate a certain amount of memory space, write the content to be stored into that memory, and then write the memory content to the index file when the memory is full. To improve retrieval speed, in practical applications, the index content can be sorted by message timestamps and saved before the index file is closed, so that the content of the index file can be quickly located using a fast search method when searching the index file content.

[0048] See Figure 3 The signaling message retrieval process involves the system's database, message interpretation module, and message retrieval module. The following section will combine these components... Figure 3 The above process will be explained in detail.

[0049] See also Figure 3 When a user retrieves the required XDR document from the database using the web application based on query criteria, the system can perform drill-down analysis on the XDR document for which signaling messages need to be retrieved. Specifically, after the web application sends a signaling retrieval request to the message retrieval module, the module can locate the corresponding index file based on the timestamp carried in the request. After loading the index file into memory, a fast lookup method is used to retrieve the data packet length and position offset of the corresponding XDR ID. Simultaneously, the message retrieval module can load the message file into memory, and further, based on the position offset and data packet length, retrieve at least one target signaling message. Finally, the message interpretation module can convert the message content into a readable format and send it to the corresponding web application for user viewing.

[0050] The beneficial effects of the above technical solution are as follows: In the process of storing and retrieving signaling messages, by introducing index files, not only is the problem of large data space occupation caused by the large amount of signaling message data solved, but it is also conducive to quickly locating the content of signaling messages, improving the retrieval efficiency of signaling messages and the user experience.

[0059] Based on the above technical solutions, the signaling data packet acquisition module includes a message file generation unit to be retrieved, a signaling message association unit, and an external data representation data generation unit.

[0061] The signaling message association unit is used to associate signaling messages belonging to the same session according to the session identifier carried by each signaling message.
