Description

IP address configuration method, device and network system

Technical Field

The present invention relates to the field of data communication technologies, and in particular, to a method, an apparatus, and a network system for configuring an IP address.

Background

For LTE (Long Term Evolution) networks, user name and password authentication and IP (internet protocol) address delivery occur during the registration phase of the network. In the LTE Network, LAC (L2TP access concentrator ) and LNS (L2TP Network Server, L2TP Network LNS device) which communicate through a Layer 2Tunneling Protocol (L2 TP) are included. When allocating IP to a device, LNS generally randomly allocate addresses in an address pool, and the IP address obtained by the device changes every time the device comes online. If a fixed static IP needs to be specified for a device, currently, a matching is usually set separately for an identifier of the device or information such as an International Mobile Subscriber Identity (IMEI) at an LNS end, and the configuration method is inefficient and prone to errors.

Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. It should be noted that the terms "first," "second," and the like are used merely to distinguish one description from another, and are not intended to indicate or imply relative importance.

At present, if a fixed static IP is specified for a terminal device, an LNS end usually sets and matches the identifier or IMEI of the device separately. For example, if IP is assigned to the SysID (System Identity) of the terminal device, if there are a plurality of System modules in the device, the device cannot be distinguished from each other, and the terminal device needs to be replaced and reconfigured. If IP is allocated for IMEI of terminal equipment (or module), when new equipment, a problem module is replaced and equipment is replaced, the IMEI code of the module needs to be acquired in advance, and the error of the acquired IMEI code or the configuration error needs to be confirmed back and forth, so that the static IP address configuration efficiency is low and the static IP address configuration is easy to make errors.

In view of the above problems, the applicant of the present application has conducted long-term research and research to propose the following embodiments to solve the above problems. The embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 1, a network system 10 provided in the embodiment of the present application includes a terminal device 20, an LAC device 30, and an LNS device 40. The terminal device 20 may establish a communication connection with the LAC device 30 through the network to perform data interaction, and the LAC device 30 may establish a communication connection with the LNS device 40 through the network to perform data interaction. For example, the terminal device 20 may transmit the internet access request information to the LAC device 30 through the network, and the LAC device 30 may transmit the internet access request information to the LNS device 40 through the network. The internet access request information may be used for the terminal device 20 to apply for network registration and IP address allocation for network access to the LNS device 40. Additionally, the network may be, but is not limited to, a wired network or a wireless network.

Understandably, the terminal device 20, the LAC device 30, and the LNS device 40 in the network system 10 may cooperate with each other to perform or implement the IP address configuration method described below.

The terminal Device 20 may be, but is not limited to, a smart phone, a Personal Computer (PC), a tablet PC, a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), and the like. When the terminal device 20 needs to interact with other devices and platforms (e.g., an intranet, an extranet, etc.) through a private network, registration for network entry and configuration of a static IP address are required. The private network may be, but is not limited to, a 4G private network, a 5G private network, and the like.

LAC is an english abbreviation of L2TP Access Concentrator, LAC or LAC device 30 both refer to an Access Concentrator supporting L2TP (Layer 2Tunneling Protocol), LAC device 30 is a device provided by an operator, and may be used as a bridge for information interaction between terminal device 20 and LNS device 40. For example, the LAC device 30 may be configured to transmit the internet access request information received from the terminal device 20 to the LNS device 40, and transmit the static IP received from the LNS device 40 to the terminal device 20.

The LNS is abbreviated as L2TP Network Server in english, and the LNS or the LNS device 40 both refer to a Network Server supporting L2TP, and can be used to issue a static IP address to the terminal device 20 through the LAC device 30. In addition, the LNS may also be used to perform network registration for network entry of the terminal device 20.

Referring to fig. 2, the IP address configuration method provided in the embodiment of the present application may be applied to the terminal device 20 and the LNS device 40, and the terminal device 20, the LNS device 40 and the LAC device 30 cooperate to execute or implement the steps of the method. The steps of the IP address configuration method will be described in an interactive manner, wherein the method may include steps S210 to S260, as follows:

step S210, the terminal device 20 sends Internet access request information to the LAC device 30, wherein the Internet access request information comprises user information of the terminal device 20, and the user information carries specified IP information;

step S220, the LAC device 30 sends the internet access request information received from the terminal device 20 to the LNS device 40;

step S230, the LNS device 40 extracts the specified IP information carried by the user information from the user information of the internet access request information received by the LAC device 30;

step S240, the LNS device 40 determines the static IP of the terminal device 20 based on the specified IP information;

step S250, the LNS device 40 sends the static IP to the LAC device 30;

step S260, the LAC device 30 sends the static IP to the terminal device 20, so that the terminal device 20 obtains the static IP.

In this embodiment, after the terminal device 20 sends the internet access request information to the LAC device 30, the LAC device 30 may send the internet access request information to the LNS device 40. The internet access request information may be used by the LNS device 40 to allocate a static IP to the terminal device 20, and in addition, the internet access request information may also be used by the LNS device 40 to perform network registration for a private network for the terminal device 20. After the terminal device 20 completes network registration, it can access the corresponding device and platform by using the private network.

Understandably, when the terminal device 20 needs to perform network registration of the private network, the terminal device 20 may send the internet access request message to the LAC device 30. The user information in the internet access request information may include a user name and specified IP information of the terminal device 20. The user name may be determined according to the user who uses the terminal device 20. The specified IP information may be an IP address or a mask corresponding to the IP address, and may be set by the user according to the actual situation.

It should be noted that, at present, the user information of the internet access request information for network registration does not generally include the specified IP information. In the IP address configuration method provided by the application, the appointed IP information can be added in the field of the user information of the Internet access request information, so that the user information and the Internet access request information carry the appointed IP information. In the embodiment of the present application, the internet registration flow of the terminal device 20 is not changed, the specified IP information is carried in the user information of the terminal device 20 included in the existing internet request information, and the purpose of sending the specified IP information is achieved by multiplexing the user information field.

In this embodiment, the designated IP information corresponds to a designated IP, and if the designated IP information itself is an IP address, the designated IP corresponding to the designated IP information is the designated IP information itself; if the designated IP information is a mask, the designated IP corresponding to the designated IP information is an IP converted by the mask. The specified IP corresponding to the specified IP information can be understood as an IP address that the user wants the LNS device 40 to configure for the terminal device 20. After the LNS device 40 analyzes the designated IP corresponding to the designated IP information from the internet access request information, the validity of the designated IP needs to be authenticated, and after the LNS device 40 determines that the designated IP is valid, the IP address of the terminal device 20 is configured as the designated IP.

In this embodiment, the internet access request information may be a request message, and the request message may include a user name, a mask, and the like of the terminal device 20. The user name and the mask may be isolated by special characters, so that the LNS device 40 may analyze the user name and the mask from the request packet. The special characters can be characters different from english letters and numbers, and can be set according to actual conditions, for example, the special characters can be, but are not limited to, "#", "-" and the like.

It should be noted that the mask corresponds to the IP address, and may be a subnet mask. The translation between an IP address and a mask corresponding to the IP address is a means well known to those skilled in the art. For example, the class B IP address 167.194.0.0 is divided into 28 subnets, the subnet mask for the class B address is 255.255.0.0, and the host address for the class B address is the last 2 bits (i.e., 0-255.1-254). Thus, 255.255.248.0 can be obtained by setting all the first 5 bits of the host address in the subnet mask 255.255.0.0 to 1, and the set of values is the subnet mask of the class B IP address 167.194.0.0 divided into 28 subnets.

In addition, a static IP (static IP address, also referred to as a fixed IP address) can be understood as an IP address that is allocated to the terminal device 20 for a long time and used, without change. Therefore, the terminal device 20 does not need to automatically acquire the network address when connecting to the network, and the network connection of the terminal device 20 is simplified.

At present, if the LNS device 40 configures a static IP for the terminal device 20 separately for the identification code or the IMEI of the terminal device 20, the identification code or the IMEI cannot be flexibly acquired when the terminal device 20 is replaced, and in addition, an error is easily generated when the identification code or the IMEI is acquired, so that the efficiency of IP address configuration is low and an error is easily generated. In this embodiment, the terminal device 20 sends the internet access request information carrying the specified IP information to the LAC device 30, so that the LAC device 30 sends the internet access request information to the LNS device 40. After receiving the internet access request message, the LNS device 40 may issue a static IP for the terminal device 20 based on the specified IP information carried in the internet access request message, so as to avoid the LNS device 40 configuring the static IP for the terminal device 20 separately for the identification code or the IMEI of the terminal device 20. When the terminal device 20 changes, the LNS device 40 may also configure the static IP of the changed device based on the internet access request information sent by the changed device through the LAC device 30, so as to improve the problems of low efficiency and error proneness to the IP address configuration.

As an alternative implementation, step S240 may include: the LNS equipment 40 verifies the validity of the specified IP corresponding to the specified IP information; when the specified IP is valid, LNS device 40 determines the specified IP as the static IP; when the specified IP is invalid, the LNS device 40 determines an unallocated IP address from an address pool stored in the LNS device 40 as the static IP, wherein the address pool comprises at least one unallocated IP address.

In this embodiment, the LNS device 40 can authenticate the validity of the specified IP information (or the specified IP) by using its own stored address pool. For example, the LNS device 40 may directly match the specified IP information (mask) with the IP in the address pool to verify the validity of the specified IP information by specifying the IP information as the mask.

For another example, after the LNS device 40 parses the specified IP information from the internet request information, it may determine the specified IP corresponding to the specified IP information based on the specified IP information, and then compare the specified IP with the IP in the address pool to verify the validity of the specified IP. The principle of determining the designated IP corresponding to the designated IP information may be: if the designated IP information is the IP address, the designated IP corresponding to the designated IP information is the designated IP information; if the designated IP information is a mask, the designated IP corresponding to the designated IP information is an IP converted by the mask.

When it is determined that the specified IP information (or the specified IP) is valid, the LNS device 40 regards the specified IP as a static IP and transmits the static IP to the terminal device 20 through the LAC device 30. When it is determined that the designated IP information (or designated IP) is invalid, the LNS device 40 selects an IP which is not allocated for use from the address pool as a static IP, and transmits the static IP to the terminal device 20 through the LAC device 30.

If all the IPs in the address pool in the LNS device 40 are allocated and there is no static IP that is not allocated, a prompt may be sent to the terminal device 20 through the LAC device 30 to enable the user to take appropriate action (e.g., add a new IP in the address pool) to ensure that the terminal device 20 can allocate a static IP. Alternatively, LNS device 40 automatically takes appropriate action, such as adding a new IP in the address pool, or other action.

It should be noted that the address pool typically stores a plurality of IP addresses, and one or more unused IP addresses usually exist in the plurality of IP addresses. Of course, there may be one or more IP addresses that have already been assigned, among the plurality of IP addresses. The number of IP addresses in the address pool may be set according to actual conditions, and the number of IP addresses in the address pool is not particularly limited.

As an optional implementation manner, the specified IP information includes a mask corresponding to the specified IP. The process of the LNS device 40 verifying the validity of the specified IP may include: judging whether the address pool has the same IP address as the designated IP corresponding to the mask; when the IP address identical to the designated IP does not exist in the address pool, determining that the designated IP is invalid; determining that the designated IP is invalid when the same IP address as the designated IP exists in the address pool and the same IP address as the designated IP is allocated; determining that the designated IP is valid when the same IP address as the designated IP exists in the address pool and the same IP address as the designated IP is not allocated.

For example, when the IP (designated IP) corresponding to the mask is 167.194.0.0 and the LNS device 40 detects that there is no IP "167.194.0.0" in the address pool when verifying the validity of "167.194.0.0", it indicates that the designated IP "167.194.0.0" is invalid and cannot pass the verification. If it is detected that there is an IP of "167.194.0.0" in the address pool and the IP has been assigned, it indicates that the designated IP "167.194.0.0" is invalid and cannot be verified. If an IP of "167.194.0.0" is detected in the address pool and is not assigned, then the designated IP of "167.194.0.0" is valid and verified.

Optionally, the method may further comprise: the terminal device 20 determines whether the static IP is the same as the designated IP corresponding to the designated IP information; when the static IP is different from the specified IP, the terminal device 20 obtains an analysis result from the LNS device 40, where the analysis result includes a reason why the static IP is different from the specified IP.

In this embodiment, after obtaining the static IP, the terminal device 20 may determine whether the static IP is the same as the specified IP in the previous internet access request message. If not, the reason is acquired from the LNS device 40. When allocating the static IP for the terminal device 20, the LNS device 40 may record the allocation process, where the record may be an analysis result of the LNS device 40.

Understandably, the analysis results (reasons why static IP is not the same as the specified IP) may include: specifying that the IP does not exist in the address pool; the designated IP exists in the address pool but is already allocated.

The user can intuitively know the reason why the static IP is different from the specified IP from the analysis result. After the user knows the reason, when the static IP is configured for other devices, the configuration process can be improved based on the reason so as to improve the efficiency of the static IP address configuration.

As an optional implementation, the method may further include: the terminal device 20 determines whether the static IP is the same as the designated IP corresponding to the designated IP information; when the static IP is different from the specified IP, the terminal device 20 acquires and displays an address pool stored in the LNS device 40 from the LNS device 40 (or, the terminal device 20 acquires and displays an address pool stored in the LNS device 40 from the LNS device 40 through the LAC device 30), where the address pool includes a plurality of IP addresses and an allocation status corresponding to each IP address.

In the present embodiment, the allocation status of the IP address includes two statuses, allocated or unallocated. Allocated means that the IP address is already occupied and cannot be allocated to the terminal device 20 as a static IP. Being unassigned indicates that the IP address is unoccupied and may be assigned to terminal device 20 as a static IP.

When the static IP allocated to the terminal device 20 is different from the designated IP, the user can view the IP addresses in the address pool and the corresponding allocation status through the terminal device 20. Based on the viewed result, the user can select the unused IP from the address pool again as new specified IP information to cause the LNS device 40 to allocate the selected unused IP to the terminal device 20 as a static IP, thereby allowing the user to dynamically adjust the corresponding static IP on site.

In this embodiment, if the terminal device 20 supports the function of the multi-user list, different static IP segments can be dynamically switched by switching different dialing parameters.

In addition, if the terminal device 20 needs to be replaced, the device module needs to be replaced, a new device needs to be added, and the device needs to be shifted (replacing the terminal device 20, the device module needs to be replaced, the new device needs to be added, and the device shift means that the user name of network registration needs to be changed), a corresponding configuration needs to be introduced into the changed device end, so that the internet access request information sent during network registration only includes the user name and the specified IP information, and the LNS end does not need to individually configure the static IP for the changed terminal, thereby simplifying the configuration flow of the static IP and improving the configuration efficiency.

In order to facilitate understanding of the implementation process of the IP address configuration method, network registration is performed based on a smart phone (terminal device 20), and the implementation process of the IP address configuration method is exemplarily described below:

firstly, configuring an Access Point Name (APN) at a mobile phone end (terminal equipment 20), and then sending network registration internet Access request information to an internet server system (LNS) through a local area network (LAC), wherein the APN carries related information such as a static IP mask and the like, namely, the APN comprises an IP field isolated by special characters and a real user Name, and in addition, the APN is a parameter which needs to be configured when the smart phone accesses the internet and is used for determining a mode of the mobile phone accessing the network;

secondly, when receiving the request, the LNS can extract the information related to the static IP and the real user name from the internet request information;

thirdly, the LNS performs a 3A authentication check, if not by a direct return, at which point the network registration fails, wherein the 3A authentication check is a means well known to those skilled in the art, and includes: authentication (Authentication), verifying the identity of the user and the available network services; authorization (Authorization), opening network service to user according to authentication result; accounting (Accounting), which records the usage of various network services by the user and provides the usage to the charging system, which is not described herein again;

fourthly, after the 3A authentication check is passed, the LNS detects whether the extracted static IP is a valid and available IP, if the extracted static IP passes the check, the IP is allocated, and if the extracted static IP fails to pass the check, a new available IP is allocated from an address pool stored by the LNS as the static IP of the terminal device 20;

fifthly, after the 3A authentication check is passed, the mobile phone is successfully connected with the LNS, the mobile phone can also detect whether the mobile phone is successfully connected with the LNS, and after the successful connection is detected, the mobile phone end acquires the allocated IP address from the 4G module in a DHCP (Dynamic Host configuration protocol) mode, and at this time, a communication channel between the mobile phone and the LNS is already established;

and sixthly, the mobile phone compares and analyzes whether the IP is the same as the IP (specified IP) applied by the mobile phone, if the IP is not the same as the IP (specified IP), the mobile phone communicates with the LNS to inquire a specific reason, and the reason is informed to the user in a visual mode.

Seventhly, when the mobile phone inquires that the IP applied by the mobile phone is different from the static IP issued by the LNS, the related information of the current address pool can be inquired for the LNS and displayed on the mobile phone; this function can be user configurable to turn on and off.

Understandably, when the terminal device 20 needs to configure a static IP, the user may add a static IP address configuration to the terminal device 20 (that is, in the request of network registration, add specified IP information to the real user name, and isolate the real user name by a special character).

When the LNS performs static IP address configuration separately for the identification code of the device or the IMEI, the configuration is not easily performed due to an error of the identification code or the IMEI, so that the configuration efficiency is low and errors are easily caused. Based on the design, the LNS does not need to aim at the identification code of the equipment or information such as IMEI and the like independently, the equipment terminal actively applies for the designated IP to configure the static IP, the user can see the configuration result in time and can dynamically adjust the related configuration. Subsequent maintenance (including equipment replacement, new equipment addition and the like) can be performed by importing the corresponding configuration, so that the problems of low configuration efficiency and high possibility of errors can be solved.
