Description
Technical Field
The present invention relates to the field of internet of things communications, and in particular, to an access configuration method, an access method, and an access device.
Background
With the popularization of 4G and 5G communication technologies, more and more internet of things devices directionally access services on public clouds through internet of things cards. Namely, by installing the corresponding internet of things card, the internet of things equipment can only access specific cloud services, but cannot access other addresses.
When a user has such a directional access requirement, a dedicated APN (Access Point Name ) network needs to be applied to the operator. For example, as shown in fig. 1, user a applies for an APN network to an operator. And the operator creates an APN for the user A, allocates a plurality of terminal IP addresses for accessing the APN, writes the APN and the IP addresses into the Internet of things card, and issues the Internet of things card to the user A. And, a special tunnel (such as GRE tunnel, L2TP tunnel, etc.) is established between the operator device and the user's server a, so that the operator device communicates with the user's server a. Therefore, the Internet of things equipment A of the user A can realize the directional access to the service end A by installing the Internet of things card recorded with the APN and the IP address.
At present, the period of opening an APN network and creating a special tunnel by an operator is long, which usually requires more than 2 weeks, and the efficiency is low, so that the flexibility of user service is seriously affected. In addition, the APN network opened by the operator for the user is independent and fixed, and cannot be flexibly adjusted according to the traffic. For example, in fig. 1, the period of creating the GRE/L2TP tunnel is long, and the APN networks of the user a and the user B are independent of each other, and the number of devices that each user accesses to its service end is limited by the number of IP addresses (internet of things cards) allocated by the operator, so that flexible adjustment cannot be implemented according to the traffic.

Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Aiming at the problems in the prior art, the invention provides an access configuration method, an access method and an access device, so as to improve the opening efficiency of access service and the flexibility of user service.
In order to implement the access configuration method of the present invention, a dedicated APN network needs to be applied to an operator in advance by an access server. The access service provider is a provider for providing the directional access service for the user in the invention; the operators are providers of network services, such as chinese trunks, chinese mobile, chinese telecommunications, etc.
The application flow of the dedicated APN network depends on the service provided by the operators, and the APN application flows of different operators may be different. Currently, application for a dedicated APN network is typically done on-line (off-line). For example, the application for opening a dedicated APN network is performed by filling in an APN application table. The APN application table generally includes information such as an applicant (i.e., an access service provider), an application date, an application reason, a specific access point name (i.e., an APN name), an IP address number, a specific access point server address (i.e., an APN server address), a contact person and a contact way, and a signature or a seal of the applicant. In other embodiments, application of a private APN network may also be done on-line, i.e. the applicant submits APN application information through a specific network interface provided by the operator (e.g. an operator application or a certain page in a website).
The operator opens a special APN network for the applicant based on the APN application submitted by the applicant. Specifically, the provisioning of an APN network includes two steps as shown in fig. 2.
In step ①, a private access point is created for the applicant and a pool of IP addresses for accessing the private access point server is allocated. The names of the special access points are special access point names appointed by the applicant, and the number of the IP addresses in the IP address pool is the number appointed by the applicant. And creating a plurality of Internet of things cards according to the special access point names and the IP address pools, wherein each Internet of things card is recorded with one IP address in the special access point names and the IP address pools. The internet of things card is installed in the terminal equipment, and the terminal equipment can access the corresponding special access point service end through the IP address recorded in the internet of things card.
For example, as shown in fig. 2, if the IP address pool includes n IP addresses, n internet of things cards are correspondingly generated, and each internet of things card records an IP address and a dedicated access point name. The internet of things card is then delivered to the applicant, for example by in-plane delivery or mailing.
In step ②, a dedicated tunnel is established between the carrier device 210 and the dedicated access point server 220 specified by the applicant, where the tunnel may be, for example, a GRE (Generic Routing Encapsulation, generic routing encapsulation protocol) tunnel, an L2TP (Layer 2Tunneling Protocol, layer two tunneling protocol) tunnel, or the like, but is not limited thereto.
Through steps ① and ② above, the operator opens a private APN network for the applicant, i.e. the access server, which private APN network comprises a private access point name and a pool of IP addresses for accessing the private access point server.
Based on the operator created private APN network, the corresponding device of the access facilitator can perform the access configuration method 400 and the access method 600 of the present invention, multiplex the private APN network, and provide access services to a plurality of users.
Specifically, the configuration server 320 of the access service provider executes the access configuration method 400 of the present invention, subdivides the private APN network established by the operator, selects a plurality of IP addresses from the IP address pool as terminal IP addresses to be allocated to the user, and stores the selected terminal IP addresses in association with the server addresses of the user, so that the terminal device of the user accesses the server thereof.
The dedicated access point server 220 executes the access configuration method 600 of the present invention, and based on the association relationship between the terminal IP address and the server address configured in the method 400, when the dedicated access point server 220 receives the access data from the terminal IP address, it can determine the server address corresponding to the IP address, and forward the access data to the server, thereby implementing the access from the terminal device of the user to the server thereof.
Specific implementation steps of the access configuration method 400 and the access method 600 will be described in detail below.
FIG. 3 shows a schematic diagram of an access configuration system 300 according to one embodiment of the invention. As shown in fig. 3, the access configuration system 300 includes a requesting device 310 and a configuration server 320.
The requesting device 310 is a device located at the user side for requesting access configuration from the configuration server 320 of the access facilitator. The requesting device 310 may be, for example, a personal configured computer such as a desktop computer, a notebook computer, or a terminal device such as a mobile phone, a tablet computer, an intelligent wearable device, or an internet of things device, but is not limited thereto.
The configuration server 320 is a device located at the side of the access server for performing access configuration for the user. The configuration server 320 may be implemented as a cloud server, or a computing instance deployed in the cloud server, for example, but is not limited thereto.
The user may send an access configuration request to the configuration server 320 through the requesting device 310 to request the configuration server 320 to perform a corresponding configuration, so that the terminal device of the user can access the server in a targeted manner, but cannot access other addresses.
The terminal device of the user is a device for user production, management, service or use, including but not limited to a mobile phone, a tablet computer, an internet of things device, etc. The terminal device of the user has a corresponding service end for providing data and method call to the terminal device (specifically, the service end provides data and method call to the client program deployed in the terminal device) so that the terminal device realizes the corresponding function.
For example, in one embodiment, the terminal device is an industrial environment monitoring device for monitoring an industrial production environment, such as monitoring structured data of temperature, humidity, air pressure, etc. of a production plant. The industrial environment monitoring device can access a relational database server (Relational Database Service, RDS) for example, and upload the collected structured data such as temperature, humidity, air pressure and the like to the relational database for storage.
In another embodiment, the terminal device is, for example, a smart access device, which includes a camera, a storage module, a voice call module, and the like, and is capable of collecting and storing unstructured data such as images, videos, and audios. The intelligent access control device can access an object storage server (Object Storage Service, OSS) for example, and upload unstructured data such as images, videos, audios and the like acquired by the intelligent access control device to the object storage service for storage.
In yet another embodiment, the terminal device may be, for example, an intelligent vehicle-mounted device with edge computing capabilities capable of performing tasks such as wireless communication, navigation planning, video entertainment, etc. The intelligent vehicle-mounted equipment can access a simple log server (Simple Log Service, SLS) for example, and upload data such as the online time, the offline time, the running state and the like to the simple log server for storage; and inquiring the uploaded historical information from the simple log server.
The above three embodiments of the terminal device and its corresponding service end are given, and it should be understood by those skilled in the art that the present invention is not limited to the specific type of terminal device and its corresponding service end. For example, although in the above-described embodiment, the terminal device is an internet of things device such as an industrial environment monitoring device, an intelligent access control device, an intelligent vehicle-mounted device, or the like, the terminal device is not limited to the internet of things device. In addition to the internet of things device, the terminal device may also be a personal configured computer such as a desktop computer, a notebook computer, or a mobile terminal such as a mobile phone, a tablet computer, an intelligent wearable device, an intelligent multimedia device, or the like. These terminal devices may also implement access to their servers based on the access configuration method 400 and the access method 600 of the present invention. Regardless of the type of the terminal device and the corresponding server, the access configuration method 400 and the access method 600 of the present invention can be applied to access the terminal device to the server, i.e. the terminal device is within the protection scope of the present invention.
After the request device 310 sends an access configuration request to the configuration server 320, the configuration server 320 executes the access configuration method 400 of the present invention to perform the related configuration of access, so that the terminal device of the user can only access the server and cannot access other addresses, thereby improving the communication efficiency and security of the terminal device and reducing the communication cost.
Fig. 4 shows a flow chart of an access configuration method 400 according to one embodiment of the invention. The method 400 is performed by the configuration server 320. As shown in fig. 4, the method 400 begins at step S410.
In step S410, an access configuration request is received, the configuration request including a number of terminal IP addresses and a server address, the terminal IP addresses being used to access the server.
As described above, the access configuration request is sent by the requesting device 310, and is used to request the configuration server 320 to perform a corresponding configuration operation, so as to implement access from the terminal device to the server.
The access configuration request includes the number of terminal IP addresses and the server address. The number of the terminal IP addresses included in the configuration request is set by the user. Generally, the number of terminal IP addresses is determined according to the service scale of the user, i.e., the number of terminal devices of the user, and the number of terminal IP addresses is equal to or greater than the number of terminal devices. For example, 128 industrial environment monitoring devices are included in the application scenario of the user, and then the number of terminal IP addresses may be set to 128 or a value greater than 128.
The address of the server is the address of the server accessed by the terminal equipment. Taking the terminal equipment as industrial environment monitoring equipment and the server as a relational database server as an example, the address of the server is the address of the relational database server.
In step S410, the configuration request includes the number of terminal IP addresses and the server address, and is used to request the configuration server 320 to perform a corresponding configuration operation, so as to implement directional access from the terminal device to its server, that is, make the terminal IP address used for directional access to the corresponding server, and cannot access other addresses.
Subsequently, in step S420, in response to the configuration request, the number of IP addresses is selected from a preset IP address pool as the terminal IP address, where the IP address pool is used to access a preset dedicated access point server.
Referring to the above, the access server applies for opening a dedicated APN network to the operator in advance, where the APN network includes a dedicated access point name and an IP address pool for accessing a dedicated access point server, where the IP address pool is a preset IP address pool in step S420, and the dedicated access point server is a preset dedicated access point server in step S420. Further, the IP address pool is used for directionally accessing a preset dedicated access point server, and the dedicated access point server is only allowed to be accessed by the IP addresses in the IP address pool.
In step S420, the configuration server 320 selects the above number of IP addresses from the preset IP address pool as the terminal IP addresses in response to the configuration request sent from the requesting device 310. For example, if the number of the specified terminal IP addresses in the configuration request is 128, 128 IP addresses in the IP address pool in the configuration server 320 are selected to be allocated to the user, and are used as terminal IP addresses of the user.
According to one embodiment, step S420 further comprises the steps of: dividing an IP address pool into a plurality of sub-network segments, wherein each sub-network segment comprises a plurality of IP addresses; and selecting one or more sub-network segments from the plurality of sub-network segments as the terminal IP addresses according to the number of the terminal IP addresses specified in the configuration request.
For example, the IP address pool for directional access to the dedicated access point server is 10.0.0.0/8,/8 indicates that the first 8 bits of the network mask are 1, i.e., the network mask is 255.0.0.0, and correspondingly, the address range of the IP address pool is 10.0.0.0-10.255.255.255. The IP address pool is divided into a plurality of sub-network segments, and it should be noted that the number of IP addresses included in each sub-network segment is not limited by the present invention. For example, a 10.0.0.0/8 pool of IP addresses may be partitioned into multiple sub-segments of different sizes, such as 10.1.0.0/16, 10.2.0.0/25, 10.3.0.0/26, 10.4.0.0/27. Then, one or more sub-network segments are selected from the sub-network segments as terminal IP addresses according to the number of terminal IP addresses specified in the configuration request. For example, if the number of terminal IP addresses specified in the configuration request is 128, the user may be assigned a subnet segment 10.2.0.0/25 as the terminal IP address, the subnet segment including 10.2.0.0 to 10.2.0.127 total 128 IP addresses. For another example, if the number of terminal IP addresses specified in the configuration request is 192, then subnets 10.2.0.0/25 and 10.3.0.0/26 may be allocated to the user as terminal IP addresses, where subnets 10.2.0.0/25 include 10.2.0.0-10.2.0.127 for 128 IP addresses and subnets 10.3.0.0/26 include 10.3.0.0-10.3.0.63 for 64 IP addresses, and two subnets for 192 IP addresses.
After determining the terminal IP address from the IP address pool in step S420, step S430 is performed.
In step S430, the terminal IP address is stored in association with the server address, so that after the dedicated access point server receives the access data from the terminal IP address, the access data is forwarded to the corresponding server.
For example, if the terminal IP address determined in step S420 is 10.2.0.0/25 and the server address executed in the configuration request in step S410 is server_addr, the terminal IP address 10.2.0.0/25 is stored in association with the server_addr.
According to one embodiment, step S430 further comprises: determining a router corresponding to the terminal IP address, and storing the terminal IP address, the router address and the server address in an associated mode so that the special access point server forwards the access data to the corresponding server through the corresponding router after receiving the access data from the terminal IP address.
For example, the router corresponding to the terminal IP address 10.2.0.0/25 and 10.2.0.0/25 determined in step S420 is router1, the address is router_addr, and the server address executed in the configuration request of step S410 is server_addr, and then the terminal IP address 10.2.0.0/25, the router address router_addr and the server address server_addr are stored in association.
In the above embodiment, it is necessary to determine the router to which the terminal IP address corresponds. It should be noted that, the present invention is not limited to the determination method of the router, and any determination method is within the protection scope of the present invention. In one embodiment, the router corresponding to the terminal IP address may be determined according to the subnet segment where the terminal IP address is located. For example, 256 routers are provided, each router corresponding to a portion of IP address pool 10.0.0.0/8, router 0 corresponding to subnet segment 10.0.0/16, router 1 corresponding to subnet segment 10.1.0.0/16, router 2 corresponding to subnet segment 10.2.0.0/16, and so on. Since the terminal IP address 10.2.0.0/25 is located within the subnet segment 10.2.0.0/16, the terminal IP address 10.2.0.0/25 corresponds to router 2.
Through the access configuration method 400, the configuration server 320 configures an association relationship between the terminal IP address and the server address. Based on the association relation, when the special access point server receives the access data from the terminal IP address, the access data can be forwarded to the corresponding server to realize the access from the terminal equipment to the server.
Based on the access configuration method 400, the configuration server 220 may divide the IP address pool of the private APN network established by the operator into different network segments, each corresponding to one user, so as to multiplex the private APN network established by the operator and provide the directional access service for multiple users. This corresponds to subdividing the actual private APN network established by the operator, creating a virtual APN network corresponding to each user in the actual APN network, and allowing the terminal device of the user to access the virtual APN network in a directional manner. The directional access configuration process of the user is completed through SDN (Software Defined Network ) technology, no docking with operators is needed, the opening efficiency of the directional access service is greatly optimized, the second-level opening of the user service is supported, and the flexibility of the user service is greatly improved.
In addition, the access configuration method 400 of the present invention provides the directional access service for the user by configuring the association relationship between the terminal IP address and the server address. The number of terminal equipment accessed to the service end can be adjusted by adjusting the number of terminal IP addresses, thereby realizing the dynamic expansion and contraction of the user service scale.
According to one embodiment, in addition to the association relationship between the terminal IP address and the server address, the internet of things card corresponding to the IP addresses needs to be delivered to the user, the user installs the internet of things card in the terminal device, and the terminal device can realize access to the server.

Subsequently, in step S620, the target server address corresponding to the IP address of the terminal device is determined according to the association relationship between the pre-stored terminal IP address and the server address.
Subsequently, in step S630, the access data is forwarded to the target server.
For example, as shown in fig. 5, in step S610, the access data transmitted from the terminal device 510-1 includes the IP address 10.2.0.22. Subsequently, in step S620, according to the association relationship between the terminal IP address and the server address stored in the configuration server 320, the server address corresponding to the terminal IP address 10.2.0.0/25 is the address of the server 530-1, and the IP address 10.2.0.22 is within the address range 10.2.0.0/25, so that the target server address corresponding to the IP address 10.2.0.22 is the address of the server 530-1. Subsequently, in step S630, the access data is forwarded to the target server, i.e., to the server 530-1.
According to one embodiment, as shown in FIG. 5, the access system 500 further includes a router 520. Accordingly, step S620 further includes: and determining a target router address and a target server address corresponding to the IP address of the terminal equipment according to the association relation between the pre-stored terminal IP address, the router address and the server address. Step S630 further includes: and sending the access data and the target server address to the target router so that the target router forwards the access data to the target server.
For example, as shown in fig. 5, in step S610, the access data transmitted from the terminal device 510-1 includes the IP address 10.2.0.22. Subsequently, in step S620, according to the association relationship between the terminal IP address stored in the configuration server 320 and the router address and the server address, the router address corresponding to the terminal IP address 10.2.0.0/25 is the address of the router 520-1, the corresponding server address is the address of the server 530-1, and the IP address 10.2.0.22 is within the address range of 10.2.0.0/25, so that the destination router address corresponding to the IP address 10.2.0.22 is the address of the router 520-1, and the destination server address is the address of the server 530-1. Subsequently, in step S630, the dedicated access point server 220 sends the access data and the address of the server 530-1 to the router 520-1, so that the router 520-1 forwards the access data to the server 530-1.
