Description

Internet protocol IP address allocation method and device

Technical field

The present invention relates to the field of communications, and in particular to a method and an apparatus for allocating an IP address of an Internet Protocol.

Background technique

With the rapid development of the Internet, especially the rapid development and popularization of 3G/4G and WLAN services, the Customer Premise EquIPment (CPE) device is a relatively portable communication terminal capable of one or more Users provide network access. For ordinary users, after the CPE dials successfully and accesses the CPE to obtain the assigned private network IP (for example, 192.168.0.100), it can access the Internet. For enterprise users, you need to obtain the public IP address (such as 74.125.239.15) assigned by the network side after the CPE dials successfully after accessing the CPE, instead of the private IP address assigned by the CPE, so as to implement enterprise-level applications. At this time, the CPE acts as a bridge connecting the wan side network card and the network cable NIC. In order to meet the needs of enterprise users, the traditional approach is to use the CPE as a HUB hub so that the client accessing the CPE product can directly apply for an IP address to the fixed network, saying that the CPE is in the "traditional bridge mode" state. However, the traditional bridge mode has the following problem: all clients accessing the CPE (including some non-enterprise users) cannot access the CPE intranet resources because the client obtains the IP address assigned by the public network instead of the IP address assigned by the Router product. And the Router product does not process the data packet at this time. Assume that there are some video resources available for access on the intranet at this time. However, because the client obtains the public IP address, the intranet resources cannot be accessed. Switching from the traditional bridge mode to other modes requires manual assignment of an IP address and other complicated operations, and the user experience is not good.

In view of the above problems in the related art, an effective solution has not yet been proposed.

detailed description

It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. The invention will be described in detail below with reference to the drawings in conjunction with the embodiments.

In this embodiment, a method for allocating an Internet Protocol IP address is provided. FIG. 1 is a flowchart of a method for allocating an Internet Protocol IP address according to an embodiment of the present invention. As shown in FIG. 1, the process includes the following steps:

Step S102: The physical network card inside the CPE of the user equipment is divided into a first preset mode of the first logical network card and the second logical network card;

Step S104: When the client requests access to the CPE, the client is assigned a private network IP address of the CPE through the first bridge connected to the first logical network card, or the second bridge connected to the second logical network card is used as the client. The end assigns a public network IP address.

Through the steps S102 and S104 in this embodiment, the physical network card inside the CPE is divided into a first logical network card and a second logical network card, and the internal network IP address and the public network IP address are respectively assigned to the client through the two logical network cards. At the same time, it solves the problem that some clients in the related technology only access the public network resources while other clients cannot access the resources in the Router product, thereby improving the user experience.

The second bridge involved in the embodiment is connected to the WAN side network card of the wide area network. Therefore, the second bridge connected to the second logical network card in step S104 in this embodiment allocates a public network IP to the client. The way of the address can be achieved as follows:

Step S11: receiving a request sent by the client for applying for a public network IP address;

Step S12: Obtain a public network IP from the WAN side network card through the second bridge according to the request, and allocate the same to the client through the second logical network card.

In an application scenario of the embodiment, the manner of the foregoing steps S11 and S12 may be: after the dialing is successful, the CPE responds to the request of the application IP address sent by the client, and the current connection is performed. The second logical network card of the enterprise-level client is in the same local area network as the network-side network card. Therefore, the broadcast request for the application IP address sent by the enterprise-level client reaches the network-side network card through the second logical network card, and then reaches the network side through the network-side network card. After receiving the request for the IP address, the network side allocates the public network IP address to the client, so that the CPE can assign the public network IP address to the client.

In another optional implementation manner of this embodiment, the first logical network card involved in this embodiment includes: a network cable network card and a wireless fidelity WIFI network card. That is to say, the WIFI user and the network cable user respectively access the CPE through the WIFI network card and the network cable, and the two network cards are mounted under the same bridge, and the client obtains the private IP address assigned by the CPE.

In the embodiment, the private network IP address of the CPE is allocated to the client through the first logical network card, or the public network IP address is allocated to the client through the second logical network card. After the address, the method in this embodiment further includes:

Step S21: When receiving a request sent by the client for switching the current preset mode, the triggering client accesses the web application user interface webUI of the CPE according to the private network IP address;

Step S22: After triggering the operation corresponding to the request on the webUI, restart the CPE.

Through the above steps S21 and S22, it is known that the client only needs to access the CPE through the WIFI network card or insert the network port through the network cable to access the network port of the CPE internal network, perform corresponding operations on the webUI, and then the device automatically restarts to complete the mode switching, and saves the process. The "traditional bridge mode" allows the client to access the CPE manually by specifying the IP address through the network cable to implement professional and cumbersome operations such as logging in to the CPE webUI.

In addition, before the physical network card of the user equipment CPE is divided into the first preset mode of the first logical network card and the second logical network card, the method in this embodiment further includes: selecting the first pre-selection from the plurality of preset modes. Set the mode to initialize. That is to say, after the CPE device is powered on, it needs to perform mode judgment, and perform different initialization work for different modes.

It should be noted that the first logical network card involved in this embodiment includes: a network cable and a wireless fidelity WIFI network card.

4 is a block diagram 2 of an optional structure of an Internet Protocol IP address allocation apparatus according to an embodiment of the present invention. As shown in FIG. 4, a private network IP address of a CPE is allocated to a client through a first logical network card, or After the second logical network card allocates the public network IP address to the client, the device further includes: a triggering module 42 coupled to the distribution module 24, configured to receive the request sent by the client for switching the current preset mode by the client, The triggering client accesses the web application user interface webUI of the CPE according to the private network IP address; the restarting module 44 is coupled to the triggering module 42 and is configured to restart the CPE after triggering the operation corresponding to the request on the webUI.

Optionally, before the physical network card inside the CPE is divided into the first preset mode of the first logical network card and the second logical network card, the device further includes: selecting the first preset mode from the multiple preset modes. Initialize.

The invention is exemplified below in conjunction with an alternative embodiment of the invention;

This alternative embodiment proposes a new mode "LTE-Bridge mode" for meeting the different needs of ordinary consumers and enterprise users, and at the same time being more user-friendly and better user experience in mode switching.

The LTE-Bridge mode must be able to provide access to the internal network resources (such as accessing the webUI) for other clients accessing the CPE while accessing the CPE to obtain access to the external network. Service, at this time, the CPE internal bridge structure diagram in 4G gateway mode needs to be modified;

FIG. 5 is a block diagram of a 4G gateway mode bridge in the related art: as shown in FIG. 5, after the CPE dials successfully, the module The IP address obtained by the public network base station (for example, 74.125.239.15) is allocated to the WAN side network card usb0 of the large board; the WIFI user and the network line user respectively access the CPE through the network card ra0 and eth2, and the two network cards ra0 and eth2 are mounted on the network card. Under the same bridge br0, the client obtains the private IP assigned by the CPE (for example, 192.168.0.100). When the user accesses the external network, the private network IP packet arrives at br0, and the CPE performs NAT conversion internally, and converts the private IP address 192.168.0.100 into a public network IP address: 74.125.239.15 and then sends it to the external network, thereby realizing access to the network.

The bridge structure can only assign a private IP address to the client through the CPE. Because the public IP address on the network side cannot be assigned to the client, it does not meet the needs of enterprise users. The bridge structure needs to be modified. 6 is a block diagram of a CPE internal bridge structure in an LTE-Bridge mode according to an alternative embodiment of the present invention. As shown in FIG. 6 , a physical network eth2 is first divided into two logical NICs according to a port by using a VLAN technology. Eth2.1 and eth2.2, where eth2.1 is used to access clients that can access only the intranet resources of the CPE, and eth2.2 is used to access clients that can access external network resources.

Figure 6 retains the bridge in Figure 5 for accessing intranet resources. At the same time, the two network cards ra0 and eth2.1 mounted under br0 are used to access wifi users and network cable users to form a local area network. However, unlike FIG. 5, FIG. 6 deletes the path between the bridge br0 and the wan side network card usb0, which means that the user accessing through ra0 and eth2.1 cannot access the external network resources and can only access the internals of the CPE. Resources, which meet the needs of some users to access intranet resources (such as: open webUI) at any time.

On the other hand, CPE equipment should be able to provide Internet access services to clients accessing CPE, especially for enterprise-level users accessing enterprise-level clients (such as Cisco routers). Public network IP address, so add a new bridge network card br1, mount the wan side network card usb0 and another network cable network card eth2.2 connected to the CPE to the same bridge br1, and then make eth2.2 and usb0 Make up another LAN. After the dialup is successful, the CPE module acts as the Dynamic Host Configuration Protocol (DHCP) server in the process of assigning IP addresses, and responds after receiving the request for the IP address sent by the client. The network card eth2.2 and usb0 currently connected to the enterprise client are in the same local area network. Therefore, the broadcast request of the application IP sent by the enterprise client reaches the wan side network card usb0 via eth2.2, and then reaches the module through usb0, and the module receives the application IP. After the request is made, the client is assigned a public network IP, so that the CPE can allocate the public IP address to the enterprise client. After obtaining the public IP address, the client can access the network and implement related applications of the enterprise router.

In addition, when the user wants to switch the CPE from the LTE-Bridge mode to another mode, the client only needs to access the CPE through the WIFI or insert the network cable through the network cable to access the network port of the CPE intranet (corresponding to eth2.2 in Figure 6). NIC), the corresponding operation is performed on the webUI, and then the device automatically restarts to complete the mode switching, eliminating the need for the "traditional bridge mode" to connect the client to the CPE manually designated IP through the network cable to realize the professional and cumbersome operation of logging in to the CPE webUI.

The method steps of assigning a public network IP address by bridging in combination with the optional embodiment are described in detail below. Explain that the steps of the method include:

Step S202: Perform mode determination after the device is powered on, and perform different initialization operations for the LTE-Bridge mode and other modes (including 4G gateway mode, traditional bridge mode, etc.).

It should be noted that the present optional embodiment is discussed in detail in the LTE-Bridge mode, and other modes are not specifically discussed.

Step S204: For the LTE-bridge mode, the bridge configuration is performed as shown in FIG. 6 above. First, two bridge network cards br0 and br1 are configured, and two network cards ra0 and eth2.1 mounted under br0 are passed through the two. Users accessing the NIC can only access the internal resources of the CPE. Two NICs usb0 and eth2.2 are mounted on the br1. The usb0 is the CPE wan side network card. The client accessing the eth2.2 obtains the public network after the CPE dials successfully. The assigned IP address is used to access the Internet. The eth2.1 NIC corresponds to the LAN cable socket of the device enclosure, and the eth2.2 NIC corresponds to the LAN/WAN cable socket on the device enclosure.

Step S206: The CPE successfully dials, and the dialing action here is performed by the user accessing the CPE through the wifi or eth2.1 network card to log in to the webUI of the CPE.

Step S208: After the dialing is successful, for the LTE-Bridge mode, only the users accessing the eth2.2 network card can access the external network resources, and the users accessing through the WIFI and the users accessing the eth2.1 network card can only access the network. Intranet resources.

Step S210: If the user needs to complete the mode switching, only the client that can log in to the webUI logs in to the webUI to complete the mode switching, and the mode switching succeeds after the device restarts.

According to the manner adopted by the foregoing embodiment, 1) the purpose of allocating the public network IP to the client is achieved, which satisfies the needs of the enterprise user. That is, a network card and a CPE wan side network card are mounted on the same bridge to form a local area network, so that the client directly applies for IP to the CPE module and obtains the public network IP. 2) While allocating the public network IP to some clients, the private network IP can be allocated to other clients, which satisfies the purpose of other users accessing the CPE intranet resources; that is, the wifi network card and the network cable are attached. The other bridge is formed under the same bridge, and the IP address of the bridge is configured as the gateway address of the CPE, which realizes the purpose of some users accessing the CPE intranet resources. 3) Switching between different modes is more convenient and the user experience is better. In LTE-Bridge mode, the client can access the intranet IP address allocated by the CPE through the wifi or network cable to access the CPE intranet, so as to log in to the webUI for mode switching. This circumvents the cumbersome operation of manually specifying an IP address in the traditional bridge mode, and the user experience is better.
