Detailed Description

The inventor finds that, in the prior art, a user terminal needs to actively send a Dynamic Host Configuration Protocol (DHCP) message or an Address Resolution Protocol (ARP) message to a BRAS device to request to get online. When receiving the on-line request message of DHCP or ARP, BRAS device establishes on-line user information for user terminal, thereby completing on-line processing of user terminal and realizing accessing user terminal to network. The user terminal can then communicate with the network-side device. However, for many user terminals such as smart home devices, these user terminals cannot actively send an online request message of DHCP or APR to the BRAS device. Therefore, the user terminals cannot access the network and cannot communicate with the device on the network side, which often results in that some functions of the user terminals cannot be realized. For example, for the smart home device, it cannot receive a control instruction sent by a device such as a mobile phone, a tablet computer, or a personal computer on the network side, and therefore, a user cannot remotely control the smart home device through the network side.

Based on this, in the embodiment of the present invention, for the network device for providing the network access function for the user terminal, in the case that no online user information has been established for the user terminal in the network device, the network device may obtain the IP address of the user terminal, the MAC address of the user terminal, and the interface information of the user terminal by actively sending an ARP request to the user terminal and receiving an ARP reply after receiving a message addressed to the user terminal, or, the network device may also obtain the IP address of the user terminal, the MAC address of the user terminal, and the interface information of the user terminal by receiving configuration information issued by a server, therefore, the network equipment can establish the online user information of the user terminal based on the IP address of the user terminal, the MAC address of the user terminal and the interface information of the user terminal. Therefore, for a user terminal which cannot actively send an online request, such as an intelligent home device, network equipment can acquire the IP address of the user terminal, the MAC address of the user terminal and interface information of the user terminal and establish online user information for the user terminal under the condition that the online request of the user terminal is not received, so that the user terminal can be actively accessed into a network, and the user terminal can be communicated with equipment on the network side. For example, for the smart home device, the smart home device can receive control intelligence sent by a device such as a mobile phone, a tablet computer, and a personal computer on the network side, so that a user can remotely control the smart home device on the network side.

As an example, one of the scenarios of the embodiment of the present invention may be applied to a network system as shown in fig. 1. In the network system, a network device 101 is used to provide a user terminal 102 with a network access service, such as a BRAS device. The user terminal 103 on the network side may send a first message to the network device 101, where a destination address of the first message is an Internet Protocol (IP) address of the user terminal 102. After receiving the first message, the network device 101 may locally search for online user information of the user terminal 101 according to the IP address of the user terminal 102. If the online user information of the user terminal 102 cannot be found locally, the network device 101 may send an ARP request to the user terminal 102 based on the IP address of the user terminal 102. The user terminal 102 sends an APR response to the network device 101 after receiving the ARP request. After receiving the APR, the network device 101 may obtain a Media Access Control (MAC) address of the ue 102 and interface information of the ue based on the ARP reply. Then, the network device 101 may establish online user information of the user terminal 102 based on the IP address of the user terminal 102, the MAC address of the user terminal, and the interface information of the user terminal.

As another example, the second scenario of the embodiment of the present invention may be applied to a network system as shown in fig. 2. In the network system, a network device 201 is used for providing a user terminal 203 with network access service, such as BRAS equipment. The server 202 is used to configure the network device 201, such as a Portal server. The server 202 may send configuration information to the network device 201, where the configuration information carries an IP address of the user terminal 203, a MAC address of the user terminal, and interface information of the user terminal. After receiving the configuration information, the network device may establish online user information of the user terminal 203 based on the IP address of the user terminal 203, the MAC address of the user terminal, and the interface information of the user terminal under the instruction of the configuration information.

It can be understood that the above two scenarios are only two scenario examples provided by the embodiment of the present invention, and the embodiment of the present invention is not limited to these two scenario examples.

The following describes in detail a specific implementation manner of the method, apparatus, and system for controlling the user terminal to be online according to the embodiment of the present invention with reference to the accompanying drawings.

Fig. 3 is a flowchart illustrating a method for controlling a user terminal to be online according to an embodiment of the present invention. In this embodiment, for example, the method may specifically include:

301. the network equipment receives a first message, the network equipment is used for providing network access service for the user terminal, and the destination address of the first message is the Internet Protocol (IP) address of the user terminal.

In specific implementation, the device on the network side may initiate the first packet to the user terminal through the internet, that is, the destination address of the first packet is the IP address of the user terminal. Since the network device is configured to provide a network access service for the user terminal, the first packet is sent to the network device through the internet. The Network device may be a BRAS device, or may also be a Broadband Network Gateway (BNG) device.

302. And the network equipment searches online user information of the user terminal according to the IP address of the user terminal.

In specific implementation, after the network device receives the first packet, the IP address of the user terminal may be obtained by identifying the destination address of the first packet. In order to forward the first packet, the network device may search for online user information that matches the IP address of the user terminal. The online user information is online user information of the user terminal, and can be used by the network device to forward the first message to the user terminal. The online user information matched with the IP address of the user terminal is online user information including the IP address of the user terminal.

303. And if the online user information of the user terminal cannot be searched in the network equipment, the network equipment sends an Address Resolution Protocol (ARP) request to the user terminal based on the IP address of the user terminal.

It can be understood that, if the network device does not find the online user information of the user terminal locally, that is, the network device does not store the online user information matched with the IP address of the user terminal locally, the user terminal is not in an online state and does not access the network. At this time, the network device may transmit an ARP request to the user terminal based on the IP address of the user terminal to request the MAC address of the user terminal and the interface information of the user terminal. And the ARP request carries the IP address of the user terminal so that the user terminal can identify the ARP request. The interface information of the user terminal represents an interface on the network equipment, and the interface is used for information interaction between the network equipment and the user terminal.

In addition, if the network device can locally find the online user information of the user terminal, that is, the network device locally stores the online user information matched with the IP address of the user terminal, the user terminal is already in an online state and has access to the network. At this time, the network device may also send the first packet to the user terminal according to the interface information of the user terminal in the online user information, thereby implementing a transmission process of the first packet from a network side device to the user terminal.

304. And the network equipment receives an ARP response returned by the user terminal based on the ARP request, and acquires the MAC address of the user terminal and the interface information of the user terminal based on the ARP response.

In specific implementation, after receiving the ARP request, the user terminal may generate an ARP reply carrying its own MAC address and interface information according to the APR request, and send the ARP reply to the network device. After receiving the ARP reply, the network device may obtain the MAC address of the user terminal and the interface information of the user terminal from the ARP reply.

305. And the network equipment establishes online user information of the user terminal based on the IP address of the user terminal, the MAC address of the user terminal and the interface information of the user terminal.

After the establishment, the network device stores the online user information of the user terminal. The online user information includes an IP address of the user terminal, an MAC address of the user terminal, and interface information of the user terminal.

It can be understood that the on-line user information of the user terminal stored in the network device may have at least two roles. On the one hand, the network device can verify whether the user terminal is on line according to the on-line user information when receiving the message related to the user terminal. The messages related to the user terminal comprise messages sent to the user terminal and messages sent by the user terminal. On the other hand, when the network device receives the message addressed to the user terminal, the network device may identify the interface information of the user terminal according to the online user information, and forward the message addressed to the user terminal based on the interface information of the user terminal.

In some embodiments, in combination with the function of the online user information, after 305, this embodiment may further include: and the network equipment sends the first message to the user terminal according to the interface information of the user terminal in the online user information.

In combination with the function of the online user information, in other embodiments, after 305, this embodiment may further include: the network equipment receives a second message sent by the user terminal; and if the online user information of the user terminal is found in the network equipment, the network equipment forwards the second message. The second packet carries the IP address of the user terminal and the MAC address of the user terminal, so that the network device can search the online user information of the user terminal according to the IP address of the user terminal and the MAC address of the user terminal.

It should be noted that, in a scenario of a Virtual Customer end device (vCPE for short), the network device provides network access service for all devices of the home users, and each device of the home user is located in a network, which is a home network. Wherein the network device may assign an identity to each home network. This identification is used by all devices of the home network in order for the network device to identify devices within the home network. This identifier may be referred to as a home identifier (hereinafter, Family ID), for example. Thus, all devices within the same home network use the same home identification.

It is understood that the present embodiment may be applied to vCPE scenarios, for example. Specifically, in a vCPE scenario, the user terminal may be a device of a home user, and is located in a home network, and at this time, the user terminal uses an identifier of the home network, so that the network device identifies the user terminal in the home network. Wherein the network device identifies and determines the user terminal according to the identification of the home network, the IP address of the user terminal, and the MAC address of the user terminal. Therefore, on one hand, the online user information of the user terminal may include an identifier of the home network in addition to the IP address of the user terminal, the MAC address of the user terminal, and the interface information of the user terminal. On the other hand, the packet related to the user terminal may also carry an identifier of the home network. For example, the first packet may carry an identifier of the home network in addition to the IP address of the user terminal.

It can be understood that, in a vCPE scenario, after the network device receives the first message, the online user information to be searched needs to be matched with not only the IP address of the user terminal, but also the identifier of the home network. Thus, in a vCPE scenario, the 302 may be, for example: and the network equipment searches online user information matched with the identification of the home network and the IP address of the user terminal and takes the online user information as the online user information of the user terminal. More specifically, the 302 may include: and the network equipment searches online user information matched with the identifier of the home network, and if the online user information is found, the online user information matched with the IP address of the user terminal is searched in the online user information matched with the identifier of the home network. The 303 may be, for example: if the online user information matched with the IP address of the user terminal cannot be searched in the online user information matched with the identification of the home network, the network equipment sends an Address Resolution Protocol (ARP) request to the user terminal based on the IP address of the user terminal.

In addition, in the vCPE scenario, the second packet may also carry an identifier of the home network in addition to the IP address of the user terminal and the MAC address of the user terminal. After the network device receives the second message, the online user information to be searched needs to be matched with not only the IP address of the user terminal and the MAC address of the user terminal, but also the identifier of the home network.

With the method provided by this embodiment, for a network device that provides a network access function for a user terminal, when no online user information has been established for the user terminal in the network device, the network device may obtain an IP address of the user terminal, an MAC address of the user terminal, and interface information of the user terminal by actively sending an ARP request to the user terminal and receiving an ARP response after receiving a message sent to the user terminal, so that the network device may establish the online user information of the user terminal based on the IP address of the user terminal, the MAC address of the user terminal, and the interface information of the user terminal. Therefore, for a user terminal which cannot actively send an online request, such as an intelligent home device, network equipment can acquire the IP address of the user terminal, the MAC address of the user terminal and interface information of the user terminal and establish online user information for the user terminal under the condition that the online request of the user terminal is not received, so that the user terminal can be actively accessed into a network, and the user terminal can be communicated with equipment on the network side. For example, for the smart home device, the smart home device can receive control intelligence sent by a device such as a mobile phone, a tablet computer, and a personal computer on the network side, so that a user can remotely control the smart home device on the network side.

Fig. 4 is a flowchart illustrating a method for controlling a user terminal to be online according to an embodiment of the present invention. In this embodiment, for example, the method may specifically include:

401. the server acquires configuration information;

402. the server sends the configuration information to the network equipment;

the network device is configured to provide a network access service for a user terminal, the configuration information is used to instruct the network device to establish online user information of the user terminal based on an IP address of the user terminal, an AC address of the user terminal, and interface information of the user terminal, and the configuration information carries the IP address of the user terminal, the MAC address of the user terminal, and the interface information of the user terminal.

In some embodiments, if the network device receives a first message whose destination address is the IP address of the user terminal, the network device may search for online user information of the user terminal according to the IP address of the user terminal. If the first message is received after the network device establishes the online user information for the user terminal, the online user information of the user terminal can be found in the network device, and at this time, the network device can send the first message to the user terminal according to the interface information of the user terminal in the online user information.

In other embodiments, if the network device receives the second packet sent by the user terminal, the network device may search for online user information of the user terminal according to the IP address of the user terminal and the MAC address of the user terminal. If the first message is received after the network device establishes the online user information for the user terminal, the online user information of the user terminal can be found in the network device, and at this time, the network device can forward the second message.

In addition, in a vCPE scenario, the user terminal may be located in a home network, for example, and in the configuration information and the online user information of the user terminal, besides the IP address of the user terminal, the MAC address of the user terminal, and the interface information of the user terminal, for example, an identifier of the home network may also be included.

It can be understood that the difference between this embodiment and the embodiment shown in fig. 3 is that, in this embodiment, the network device establishes online user information for the user terminal under the trigger of the configuration information sent by the server, and the network device obtains data used for establishing the online user information, such as the IP address of the user terminal, the MAC address of the user terminal, and the interface information of the user terminal, through the configuration information sent by the server. In addition, in the embodiment, for the description related to the online user information, reference may be made to the embodiment shown in fig. 3, and details of the embodiment are not repeated herein.

It should be noted that the server may acquire the configuration information through interaction with a user, for example. Specifically, the present embodiment may further include: the server acquires a configuration instruction, wherein the configuration instruction is used for indicating the configuration of online user information for the user terminal; and the server generates configuration information according to the configuration instruction. The configuration instruction may be, for example, a configuration instruction sent by a user to a server through a device such as a mobile phone or a PC, where the configuration instruction includes an IP address input by the user, a MAC address of the user terminal, and interface information of the user terminal. In addition, in a vCPE scenario, the configuration instruction may further include an identifier of the home network.

In order to enable the server to determine whether the network device establishes online user information of the user terminal, the network device may further feed back to the server after establishing the online user information. Specifically, in some embodiments, the present embodiment may further include, for example: and the server receives a configuration success message sent by the network equipment, wherein the configuration success message is used for indicating that the network equipment establishes online user information of the user terminal. In addition, if the server does not receive the configuration success message sent by the network device, the server may determine that the online user information of the user terminal is not established on the network device.

In some embodiments, the server issues the configuration information of the configuration information amount, for example, the configuration information may be issued through a Portal protocol message. That is, the configuration information is carried in a request message of a Portal protocol sent by the server to the network device. Wherein, in the attribute field of the request message, the identifier of the home network, the IP address of the user terminal, and the MAC address of the user terminal may be carried. For example, the request message may be represented as REQ-INFO information of a Portal protocol, and the attribute field is specifically an attribute field of the REQ-INFO information. The attribute may specifically include a User-Mac field, a User-IP field, and a vCPE-Family-ID field. The User-Mac field is used for carrying the Mac address of the User terminal, the User-IP field is used for carrying the IP address of the User terminal, and the vCPE-Family-ID field is used for carrying the identifier of the home network.

In other embodiments, the configuration success message returned by the network device to the server may also be reported, for example, through a Portal protocol packet. Namely, the configuration success message is carried in a response message of a Portal protocol reported to the server by the network device. Wherein, the attribute field of the response message may carry the identifier of the home network, the IP address of the user terminal, and the MAC address of the user terminal. For example, the reply message may be represented as ACK-INFO information of a Portal protocol, and the attribute field is specifically an attribute field of the ACK-INFO information. The attribute may specifically include a User-Mac field, a User-IP field, and a vCPE-Family-ID field. The User-Mac field is used for carrying the Mac address of the User terminal, the User-IP field is used for carrying the IP address of the User terminal, and the vCPE-Family-ID field is used for carrying the identifier of the home network. It should be noted that, if the response message returned to the server by the network device does not carry the identifier of the home network, the IP address of the user terminal, and the mac address of the user terminal, the server may determine that the network device does not establish online user information for the user terminal, that is, the response message is a configuration unsuccessful message.

With the method provided by this embodiment, for a network device providing a network access function for a user terminal, in a case that no online user information has been established for the user terminal in the network device, the network device may obtain an IP address of the user terminal, an MAC address of the user terminal, and interface information of the user terminal by receiving configuration information issued by a server, thereby establishing online user information of the user terminal. Therefore, for a user terminal which cannot actively send an online request, such as an intelligent home device, network equipment can acquire the IP address of the user terminal, the MAC address of the user terminal and interface information of the user terminal and establish online user information for the user terminal under the condition that the online request of the user terminal is not received, so that the user terminal can be actively accessed into a network, and the user terminal can be communicated with equipment on the network side. For example, for the smart home device, the smart home device can receive control intelligence sent by a device such as a mobile phone, a tablet computer, and a personal computer on the network side, so that a user can remotely control the smart home device on the network side.
