Abstract
Description
Technical Field
[0001] This application relates to the field of communication technology, and in particular to a method, apparatus, electronic device, and storage medium for obtaining network addresses. Background Technology
[0002] As my country's communication network continues to expand, the number of base stations and base station equipment is gradually increasing. These base stations are usually deployed in a decentralized manner, and each base station equipment room is equipped with streaming media cameras, which can provide 24 / 7 real-time video monitoring of the equipment room.
[0003] When users need to view streaming media data within a data center, access is typically initiated based on the network address of the streaming media camera within a dedicated network. However, with the continuous increase in the number of base stations, each new base station requires the deployment of a new dedicated line, inevitably consuming significant physical line access resources. Furthermore, using the network address of a dedicated network also results in the fixed occupation of network resources. Therefore, the existing method of obtaining network addresses for base station streaming media platforms suffers from high resource consumption. Summary of the Invention
[0004] The purpose of this application is to provide a network address acquisition method, apparatus, electronic device, and storage medium to solve the problem of high resource consumption in existing base station streaming media platform network address acquisition methods.
[0005] In a first aspect, embodiments of this application provide a network address acquisition method, applied to a Network Address Translation (NAT) server in a base station streaming media platform, comprising:
[0006] The system receives an intranet binding request sent by the streaming media request unit in the base station streaming media platform. The intranet binding request carries the intranet IP address of the target edge gateway, and the target edge gateway establishes a network connection with at least one streaming media camera through the intranet.
[0007] Based on the intranet binding request, allocate an external network port to the streaming media request unit;
[0008] Bind the internal network IP address to the external network port to obtain a binding result, the binding result including the port information of the internal network IP address and the external network port;
[0009] The binding result is sent to the streaming media request unit. The binding result is used by the streaming media request unit to concatenate the internal network IP address with the port information of the external network port to form an access Uniform Resource Locator (URL), so that the streaming media request unit can obtain the streaming media of the at least one streaming media camera by accessing the URL.
[0010] Secondly, embodiments of this application provide a network address acquisition method, applied to a streaming media request unit in a base station streaming media platform, comprising:
[0011] Identify the target edge gateway;

[0013] Receive the binding result sent by the NAT server, the binding result including the internal network IP address and the external network port information, the external network port being allocated by the NAT server based on the internal network binding request;
[0014] The binding result is parsed to obtain the internal network IP address and the port information of the external network port. The internal network IP address and the port information of the external network port are concatenated to form a Uniform Resource Locator (URL). The streaming media of the at least one streaming media camera is obtained by accessing the URL.
[0015] Thirdly, embodiments of this application provide a network address acquisition device, comprising:
[0016] The receiving module is used to receive an intranet binding request sent by the streaming media request unit in the base station streaming media platform. The intranet binding request carries the intranet IP address of the target edge gateway, and the target edge gateway establishes a network connection with at least one streaming media camera through the intranet.
[0017] The allocation module is used to allocate an external network port to the streaming media request unit based on the intranet binding request;
[0018] A binding module is used to bind the internal network IP address to the external network port and obtain a binding result, wherein the binding result includes port information of the internal network IP address and the external network port;
[0019] The sending module is used to send the binding result to the streaming media request unit. The binding result is used by the streaming media request unit to concatenate the intranet IP address and the port information of the external port to form a Uniform Resource Locator (URL), so that the streaming media request unit can obtain the streaming media from the at least one streaming media camera by accessing the URL.
[0020] Fourthly, embodiments of this application provide a network address acquisition device, including:
[0021] The determination module is used to determine the target edge gateway;
[0022] The sending module is used to send an intranet binding request to the Network Address Translation (NAT) server. The intranet binding request carries the intranet IP address of the target edge gateway, and the target edge gateway establishes a network connection with at least one streaming media camera through the intranet.
[0023] The receiving module is used to receive the binding result sent by the NAT server. The binding result includes the internal network IP address and the port information of the external network port generated by the NAT server.

[0024] The splicing module is used to parse the binding result to obtain the internal network IP address and the port information of the external network port, splice the internal network IP address and the port information of the external network port to form a Uniform Resource Locator (URL), and obtain the streaming media of the at least one streaming media camera by accessing the URL.
[0025] Fifthly, embodiments of this application provide an electronic device, including: a memory, a processor, and a program or instructions stored in the memory and executable on the processor, wherein when the program or instructions are executed by the processor, they implement the steps in the network address acquisition method as described in the first or second aspect of embodiments of this application.
[0026] In a sixth aspect, embodiments of this application provide a readable storage medium storing a program or instructions, which, when executed by the processor, implement the steps in the network address acquisition method as described in the first or second aspect of embodiments of this application.
[0027] In this embodiment, the streaming media request unit in the base station streaming media platform sends an intranet binding request. This request carries the intranet IP address of the target edge gateway. The target edge gateway establishes a network connection with at least one streaming media camera via the intranet. The NAT server allocates an external network port to the streaming media request unit based on this binding request and binds the intranet IP address with the port information of the external network port to obtain a binding result. After the NAT server sends this binding result to the streaming media request unit, the unit parses the binding result to obtain the intranet IP address and the port information of the external network port, concatenates them to form a URL, and accesses the URL to obtain streaming media from at least one streaming media camera. Since the access URL generated when a user has a streaming media access need is bound in real-time between the target edge gateway's intranet IP address and the external network port allocated by the NAT server, no dedicated line is required, and no fixed network address is occupied, effectively reducing the resource consumption of the base station streaming media platform when obtaining network addresses.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

It should be understood that such usage can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0037] The network address acquisition method provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.
[0038] Please see Figure 1 , Figure 1 This is a block diagram of a base station streaming media platform provided in an embodiment of this application. The base station streaming media platform includes a streaming media request unit 101, a network address translation (NAT) server 102, an edge gateway 103, and a streaming media camera 104.
[0039] Among them, the streaming media request unit 101 is the front-end interface of the base station's streaming media platform. Users initiate access requests in the streaming media request unit. The streaming media request unit generally refers to a WEB system, but is not limited to it.
[0040] NAT server 102 is the core unit of the base station's streaming media platform. It performs internal and external network address binding based on the received streaming media requests to complete the network tunnel construction and feeds back the binding results to the streaming media request unit.
[0041] Edge gateway 103 is an intelligent device that connects to the NAT server and manages streaming media camera device 104. It can access the intranet via VPN dial-up. On one hand, the edge gateway is responsible for collecting on-site data and pulling streaming media data captured by the streaming media camera. On the other hand, the edge gateway can aggregate unstructured video data and IoT data sent from various sensing devices in the data center, perform preprocessing, trigger action responses according to predetermined rules, and upload the processing results and related data to the cloud.
[0042] The streaming media camera 104 is a terminal device that provides streaming media data and is deployed in the base station equipment room. Each edge gateway 103 establishes a network connection with at least one streaming media camera 104 through the intranet.
[0043] Please see Figure 2 , Figure 2 This is a flowchart illustrating a network address acquisition method provided in an embodiment of this application. This method is applied to a NAT server in a base station streaming media platform, such as... Figure 2 As shown, it includes the following steps:
[0044] Step 201: Receive an intranet binding request sent by the streaming media request unit in the base station streaming media platform. The intranet binding request carries the intranet IP address of the target edge gateway. The target edge gateway establishes a network connection with at least one streaming media camera through the intranet.
[0045] In this embodiment of the application, when a user needs to view streaming media data in a certain data center, they can retrieve the edge gateway device in the data center on the WEB page, and then click the streaming media view button. At this time, the WEB program will send the internal IP of the edge gateway device to the network binding interface of the NAT server to initiate an internal network binding request.
[0046] Optionally, the aforementioned edge gateway and at least one streaming media camera are connected in a serial networking mode. In this serial networking mode, the streaming media camera is directly connected to the local interface of the edge gateway, or it is aggregated through intermediate devices such as switches and routers and then connected to the edge gateway to realize real-time video monitoring, historical video playback, camera management, intelligent inspection, alarm event management, and AI intelligent analysis.
[0047] Step 202: Allocate an external network port to the streaming media request unit based on the intranet binding request;
[0048] In this embodiment, the external network port is randomly selected by the NAT server from ports 1024-65535 on the local machine and assigned to the aforementioned streaming media request unit.
[0049] Step 203: Bind the internal network IP address to the external network port to obtain the binding result. The binding result includes the port information of the internal network IP address and the external network port.
[0050] Step 204: Send the binding result to the streaming media request unit. The binding result is used by the streaming media request unit to concatenate the intranet IP address and the port information of the external port to form a Uniform Resource Locator (URL), so that the streaming media request unit can obtain the streaming media from the at least one streaming media camera by accessing the URL.
[0051] In this embodiment, an intranet binding request sent by a streaming media request unit in a base station streaming media platform is received. This intranet binding request carries the intranet IP address of a target edge gateway. The target edge gateway establishes a network connection with at least one streaming media camera via the intranet. The NAT server allocates an external network port to the streaming media request unit based on this intranet binding request and binds the intranet IP address with the port information of the external network port to obtain a binding result. After the NAT server sends this binding result to the streaming media request unit, the streaming media request unit parses the binding result to obtain the intranet IP address and the port information of the external network port, concatenates them to form a URL, and accesses the URL to obtain streaming media from at least one streaming media camera. Since the access URL generated when a user has a need to access streaming media is bound in real-time by the intranet IP address of the target edge gateway and the external network port allocated by the NAT server, no dedicated line is required, and no fixed network address is occupied, effectively reducing the resource consumption of the base station streaming media platform when obtaining a network address.
[0052] Optionally, allocating an external network port to the streaming media request unit based on the intranet binding request includes:
[0053] The intranet binding request is parsed to obtain the intranet IP address of the target edge gateway;
[0054] A probe command is periodically sent with the internal network IP address as the destination address. The probe command is used to detect whether the target edge gateway is online.
[0055] Upon receiving a response message from the target edge gateway in response to the probe command, the target edge gateway is determined to be online, and an idle port is randomly allocated from the dynamic ports of the NAT server host as the external network port of the streaming media request unit.
[0056] If no response message is received from the target edge gateway for the probe command within a preset time period, or if the number of repeated transmissions of the probe command exceeds a preset threshold, a prompt message is sent to the streaming media request unit, the prompt message indicating that the target edge gateway is offline.
[0057] In this embodiment of the application, after the NAT server resolves the internal network IP address of the target edge gateway, the curl command is first executed on the Linux system to detect whether the internal network IP address of the target edge gateway is reachable, so as to determine whether the target edge gateway device is offline.
[0058] Specifically, upon receiving a response message from the target edge gateway to the curl command, it is determined that the internal IP address of the edge gateway device is reachable. At this time, an idle port is randomly allocated from ports 1024-65535 of the NAT server host as the external port of the streaming media request unit. However, if no response message from the target edge gateway to the probe command is received within a preset time period, or if the number of repeated transmissions of the probe command exceeds a preset threshold, it is determined that the internal IP address of the edge gateway device is unreachable. In this case, a prompt message is sent to the streaming media request unit, indicating to the user that the target edge gateway is offline and cannot currently access the data of its associated streaming media camera.
[0059] In this way, by detecting whether the target edge gateway is online before binding the internal network IP address to the external network port, and only performing external network port allocation and subsequent binding and URL concatenation operations if it is confirmed to be online, it is possible to avoid the target edge gateway still trying to access when it is offline, thus further saving resource consumption.
[0060] Optionally, upon receiving feedback information from the streaming media request unit, the external network port is released, wherein the feedback information is used to instruct the streaming media request unit to acquire streaming media from the at least one streaming media camera.
[0061] In this embodiment, the NAT server periodically checks whether it receives feedback information from the streaming media request unit. This feedback information indicates whether the streaming media request unit has successfully acquired streaming media data from at least one streaming media camera. If it is confirmed that the streaming media request unit has successfully acquired streaming media data from at least one streaming media camera, the external network port is released, allowing it to be used by other processes, thus avoiding continuous occupation of network resources and further saving network resource consumption.
[0062] Please see Figure 3 , Figure 3 This is a flowchart illustrating another network address acquisition method provided in this application embodiment, applied to the streaming media request unit in a base station streaming media platform, such as... Figure 3 As shown, it includes the following steps:
[0063] Step 301: Determine the target edge gateway;
[0064] Step 302: Send an intranet binding request to the NAT server. The intranet binding request carries the intranet IP address of the target edge gateway. The target edge gateway establishes a network connection with at least one streaming media camera through the intranet.
[0065] Step 303: Receive the binding result sent by the NAT server. The binding result includes the port information of the internal network IP address and the external network port. The external network port is allocated by the NAT server based on the internal network binding request.
[0066] Step 304: Parse the binding result to obtain the intranet IP address and the port information of the external port. Concatenate the intranet IP address and the port information of the external port to form a Uniform Resource Locator (URL). Obtain the streaming media from the at least one streaming media camera by accessing the URL.
[0067] Optionally, the streaming media request unit stores a mapping relationship between at least one streaming media camera and an edge gateway, and the step of determining the target edge gateway includes:
[0068] Identify a first streaming media camera, which is the streaming media camera that the streaming media request unit wants to access;
[0069] Based on the mapping relationship between the at least one streaming media camera and the edge gateway, a target edge gateway is determined, wherein the target edge gateway is the edge gateway corresponding to the first streaming media camera.
[0070] It should be noted that this embodiment is used as... Figure 2 The implementation method of the streaming media request unit corresponding to the illustrated embodiment can be found in the following examples. Figure 2 The embodiments shown herein, and the benefits achieved therein, will not be repeated here to avoid repetition.
[0071] It should be noted that the network address acquisition method provided in this application embodiment can be executed by a network address acquisition device, or by a control module within that network address acquisition device for executing the network address acquisition method. This application embodiment uses the execution of the network address acquisition method by a network address acquisition device as an example to illustrate the network address acquisition device provided in this application embodiment.
[0072] Please see Figure 4 , Figure 4 This is a schematic diagram of the structure of a network address acquisition device provided in an embodiment of this application, as shown below. Figure 4 As shown, the device 400 includes:
[0073] The receiving module 401 is used to receive an intranet binding request sent by the streaming media request unit in the base station streaming media platform. The intranet binding request carries the intranet IP address of the target edge gateway, and the target edge gateway establishes a network connection with at least one streaming media camera through the intranet.
[0074] Allocation module 402 is used to allocate an external network port to the streaming media request unit based on the intranet binding request;
[0075] The binding module 403 is used to bind the internal network IP address to the external network port and obtain a binding result, wherein the binding result includes the port information of the internal network IP address and the external network port;
[0076] The sending module 404 is used to send the binding result to the streaming media request unit. The binding result is used by the streaming media request unit to concatenate the intranet IP address and the port information of the external port to form an access Uniform Resource Locator (URL), so that the streaming media request unit can obtain the streaming media of the at least one streaming media camera by accessing the URL.
[0077] Optionally, the allocation module can be used for:
[0078] The intranet binding request is parsed to obtain the intranet IP address of the target edge gateway;
[0079] A probe command is periodically sent with the internal network IP address as the destination address. The probe command is used to detect whether the target edge gateway is online.
[0080] Upon receiving a response message from the target edge gateway in response to the probe command, the system determines that the target edge gateway is online and randomly allocates an idle port from the dynamic ports of the NAT server host as the external network port of the streaming media request unit.
[0081] Optionally, the above-mentioned device 400 may further include:
[0082] The prompting module is used to send a prompt message to the streaming media request unit when no response message is received from the target edge gateway for the probe command within a preset time period, or when the number of repeated transmissions of the probe command exceeds a preset threshold. The prompt message is used to indicate that the target edge gateway is in an offline state.
[0083] Optionally, the above-mentioned device 400 may further include:
[0084] The release module is used to release the external network port upon receiving feedback information sent by the streaming media request unit, wherein the feedback information is used to instruct the streaming media request unit to obtain streaming media from the at least one streaming media camera.
[0085] It should be noted that the aforementioned device 400 is capable of achieving Figure 2 The various processes implemented by the device in the method embodiment will not be described again here to avoid repetition.
[0086] The apparatus in this embodiment receives an intranet binding request sent by a streaming media request unit in a base station streaming media platform. This intranet binding request carries the intranet IP address of a target edge gateway. The target edge gateway establishes a network connection with at least one streaming media camera via the intranet. A NAT server allocates an external network port to the streaming media request unit based on the intranet binding request and binds the intranet IP address with the port information of the external network port to obtain a binding result. After the NAT server sends the binding result to the streaming media request unit, the streaming media request unit parses the binding result to obtain the intranet IP address and the port information of the external network port, concatenates them to form a URL, and accesses the URL to obtain streaming media from at least one streaming media camera. Since the access URL generated when a user has a need to access streaming media is bound in real-time by the intranet IP address of the target edge gateway and the external network port allocated by the NAT server, no dedicated line is required, and no fixed network address is occupied, effectively reducing the resource consumption of the base station streaming media platform when obtaining a network address.
