Detailed Description
The following describes in detail embodiments of the present invention with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
Currently, many users have their own wireless network access devices, but the mobile terminals of the users can only transmit data through the wireless network access devices within the coverage area of the wireless network access devices. When the user leaves the coverage area of the wireless network access device, the mobile terminal of the user cannot use the wireless network access device to transmit data even if the wireless network access device is in an idle state.
Although the mobile terminal can search for a wireless network provided by another private wireless network access device which does not belong to the mobile terminal at this time, it is difficult for the other private wireless network access device to confirm the authenticity of the mobile terminal of the user. In view of access security issues, other private wireless network access devices also provide little wireless network connectivity to non-home mobile terminals.
In order to solve the problems, the invention provides a wireless network access method based on a wireless network access system. Wherein, wireless network access system includes: the system comprises an address server, a forwarding server, a wireless network access device, a mobile terminal and an operator customer service system.
The address server is a server which is established in the public network in advance, and the address server can be in signal connection with the wireless network access device.
The forwarding server is a transfer server for communication between the wireless network access devices, and is used for improving the communication security between the wireless network access devices, avoiding security holes existing in direct communication between the wireless network devices and reducing the risk of hacking of the wireless network access devices.
The wireless network access device comprises a first wireless network access device and a second wireless network access device. The first wireless network access device is a wireless network access device corresponding to the mobile terminal, for example, the first wireless network access device may be a home WiFi access point of the mobile terminal. The mobile terminal and the first wireless network access device have a shared key, and the shared key is stored in the first wireless network access device as a first preset key and stored in the mobile terminal as a second preset key.
The second wireless network access device is a wireless network access device which has no corresponding relationship with the mobile terminal, for example, the second wireless network access device may be a WiFi access point of other households. It should be noted that the network information of the wireless network corresponding to the second wireless network access device may include a shared identifier, for example, a network name of the wireless network may be suffix @ share identifier. The shared identifier indicates that the second wireless network access device corresponding to the wireless network can provide wireless network access service for the non-home mobile terminal under the condition that the non-home mobile terminal is verified to be safe.
The carrier customer service system is a customer service system of a carrier to which the wireless network access device belongs.
Fig. 1 is a wireless network access method provided in an embodiment of the present invention, which is applied to a second wireless network access device. As shown in fig. 1, the method comprises the steps of:
and step S101, receiving a wireless network access request sent by the mobile terminal.
The wireless network access request comprises first network Address information of a first wireless network access device corresponding to the mobile terminal, wherein the first network Address information comprises a first Internet Protocol (IP) Address and a first port number. The mobile terminal can be a mobile phone, a tablet or a computer and other terminals.
In the embodiment of the present invention, after a wireless Network access device (a first wireless Network device, a second wireless Network device) accesses a Network, an IP Address allocated to the wireless Network access device by an operator may be a private Network Address, or may be a public Network Address dynamically allocated from a CGN (CGN, carrier Grade Network Address Translation), that is, the IP Address may have a possibility of dynamic change. For a first wireless network device, its IP address is called a first IP address and its port number is called a first port number, and similarly, for a second wireless network device, its IP address is called a second IP address and its port number is called a second port number.
After the mobile terminal corresponding to the first wireless network access device leaves the wireless network coverage of the first wireless network access device, it is difficult for the mobile terminal to acquire the current network address information of the first wireless network access device. Therefore, the first wireless network access device may send associated terminal information to an address server disposed on the public network, where the associated terminal information includes the first network address information and a communication identifier of the mobile terminal corresponding to the first wireless network access device, and the communication identifier may be a contact address of the mobile terminal, such as a mobile phone number. After receiving the associated terminal information, the address server sends the first network address information to the mobile terminal based on the communication identifier, for example, the first network address information may be sent to the mobile terminal in a short message manner.
In one embodiment, the mobile terminal automatically searches for a wireless network when the mobile terminal is outside the coverage of the first wireless network access device. And when the searched network information of the wireless network carries the shared identifier, for example, when the @ share identifier is carried in the network name suffix of the wireless network, the mobile terminal sends a wireless network connection request to a second wireless network access device corresponding to the wireless network. The second wireless network access device performs the above step S101.
Step S102, responding to the wireless network access request, and sending a first authentication message to the first wireless network access device through the forwarding server.
The first authentication message comprises a random number and first network address information. The random number is a random number (RAND) generated by the second wireless network access device in response to the wireless network access request. Since the random number is temporarily generated by the second wireless network access device, there is uncertainty, and it is difficult for a hacker to obtain the random number in advance and perform other illegal operations.
Because the first authentication message is generated and sent by the second wireless network access device, the first authentication message also includes second network address information corresponding to the second wireless network access device, and the second network address information includes a second IP address and a second port number.
In an embodiment, the step S102 of sending, by the forwarding server, the first authentication packet to the first wireless network access device in response to the wireless network access request includes: and responding to the wireless network access request, sending a first authentication message to a forwarding server, so that the forwarding server forwards the first authentication message to a first wireless network access device based on the first network address information under the condition that the first network address information and the second network address information are subjected to security verification and pass verification through an operator customer service system.
Specifically, the step of the forwarding server performing security verification on the first network address information and the second network address information through the operator customer service system includes:
step one, after receiving the first authentication message, the forwarding server extracts first network address information and second network address information from the first authentication message, and the forwarding server sends the first network address information and the second network address information to an operator customer service system.
In some embodiments, the first wireless network access device and the second wireless network access device belong to different operators, and the forwarding server sends the first network address information to an operator customer service system of the operator to which the first wireless network access device belongs, and sends the second network address information to an operator customer service system of the operator of the second wireless network access device.
And step two, the operator customer service system inquires whether bad operation records exist in the historical operation records corresponding to the first network address information and the second network address information, and sends the inquiry result to the forwarding server.
And the query result is that the bad operation record exists or the bad operation record does not exist.
And when the inquiry result indicates that no bad operation record exists, the first network address information and the second network address information are confirmed to be safe address information, namely the safety verification of the first network address information and the second network address information is passed. After the security verification of the first network address information and the second network address information by the forwarding server through the operator customer service system is passed, the forwarding server executes the step of forwarding the first authentication message to the first wireless network access device based on the first network address information.
And when the inquiry result does not have the bad operation record, confirming that the first network address information or the second network address information possibly has potential safety hazards, namely the safety verification of the first network address information and the second network address information is not passed. In order to guarantee the safety of the first wireless network access device and the second wireless network access device, the forwarding server returns a safety risk prompt to the second wireless network access device under the condition that the safety verification of the first network address information and the second network address information is not passed. After receiving the security risk prompt, the second wireless network access device sends prompt information for refusing to provide wireless network access service due to the security risk or prompts the mobile terminal to resend a wireless network access request to the mobile terminal in order to guarantee the self security.
Step S103, receiving a first response message returned by the first wireless network device through the forwarding server.
The first response information is generated by the first wireless network device encrypting the random number by using a first preset key. Specifically, the first wireless network device encrypts, by using a first preset key and according to a predetermined encryption algorithm, the random number in the first authentication message, and generates the first response message. The embodiment of the invention does not specifically limit the pre-agreed encryption algorithm, and any appropriate encryption algorithm can be set according to actual needs.
The first preset key is a shared key which is stored by the first wireless network access device and corresponds to the mobile terminal. It should be noted that, in a case that the mobile terminal is in a coverage area of the first wireless network access device, the mobile terminal may access the first wireless network access device by using the shared key, and the shared key is stored in the first wireless network access device as the first preset key.
In one embodiment, the second wireless network access device further generates a second authentication message containing the random number after receiving the wireless network access request sent by the mobile terminal. And performs the following step S104.
And step S104, sending a second authentication message containing the random number to the mobile terminal, and receiving second response information returned by the mobile terminal.
The second response information is generated by encrypting the random number by the mobile terminal by using a second preset key. Specifically, the mobile terminal encrypts the random number in the second authentication message according to a predetermined encryption algorithm by using the second preset key, so as to generate the second response message.
The second preset key is a shared key which is stored by the mobile terminal and corresponds to the first wireless network access device. It should be noted that, in a case that the mobile terminal is in the coverage of the first wireless network access device, the mobile terminal may access the first wireless network access device by using the shared key, and the shared key is stored in the mobile terminal as the second preset key.
It should be noted that, the sequence numbers of the steps in the embodiment of the present invention do not limit the sequence of the steps in the embodiment of the present invention, and the steps are executed according to the requirements of each implementation scenario. For example, step S104 may be performed before step S102. In some implementation scenarios, step S104 may also be performed simultaneously with step S102 in order to increase the wireless network access speed.
If the first network address information and the second network address information are not verified, the second network access device may easily cause resource waste by executing step S104 before step S102 or simultaneously with step S102, and step S104 is preferably executed after step S102 or step S103 in order to avoid resource waste.
In one embodiment, the second wireless network access device receives second response information returned by the mobile terminal through a WiFi connection with the mobile terminal.
In one embodiment, after the second wireless network access device receives the first response information and the second response information, it is verified whether the first response information and the second response information are consistent. And when the first response message and the second response message are not consistent, the mobile terminal is not a mobile terminal corresponding to the first wireless network access device, the mobile terminal is not credible, and the second wireless network access device sends prompt information of authentication failure to the mobile terminal for self security.
And step S105, providing wireless network access service for the mobile terminal under the condition that the first response information and the second response information are verified to be consistent.
And if the first response message is verified to be consistent with the second response message, the mobile terminal is confirmed to be the mobile terminal corresponding to the first wireless network access device, which indicates that the mobile terminal is credible. The wireless network access service is provided for the mobile terminal under the condition that the first response information and the second response information are verified to be consistent, so that the second wireless network access device provides network connection for the non-affiliated mobile terminal under the condition of high security, and the utilization rate of network resources such as the second wireless network access device is improved. And after the mobile terminal of the user leaves the coverage range of the wireless network access device of the user, the mobile terminal can also be accessed into the wireless network through other wireless network access devices, so that the user experience is improved.
The embodiment of the invention provides a wireless network access method, which comprises the following steps: firstly, receiving a wireless network access request sent by a mobile terminal, responding to the wireless network access request, and sending a first authentication message to a first wireless network access device through a forwarding server, wherein the wireless network access request comprises first network address information of the first wireless network access device corresponding to the mobile terminal, and the first authentication message comprises a random number and the first network address information; receiving first response information returned by the first wireless network device through the forwarding server, wherein the first response information is generated by the first wireless network device encrypting the random number by using a first preset key; then, sending a second authentication message containing the random number to the mobile terminal, and receiving second response information returned by the mobile terminal, wherein the second response information is generated by encrypting the random number by the mobile terminal by using a second preset key; and finally, providing wireless network access service for the mobile terminal under the condition of verifying that the first response information is consistent with the second response information. Therefore, the wireless network access device can provide network connection for the non-affiliated mobile terminal under the condition of high security, the network resource utilization rate is improved, and the user experience is improved.
The embodiment of the invention provides another wireless network access method which is applied to a first wireless network access device. As shown in fig. 2, the method comprises the steps of:
step S201, receiving, by the forwarding server, a first authentication packet sent by the second wireless network access device in response to the wireless network access request of the mobile terminal.
The wireless network access request comprises first network address information. The first authentication message comprises a random number and first network address information of a first wireless network access device corresponding to the mobile terminal, wherein the first network address information comprises a first IP address and a first port number.
In one embodiment, after the wireless Network access device is networked, the IP Address allocated to the wireless Network access device by the operator may be a private Network Address, or may be a public Network Address dynamically allocated from CGN (carrier Grade Network Address Translation), that is, there is a possibility that the IP Address may change dynamically.
After the mobile terminal corresponding to the first wireless network access device leaves the coverage area of the first wireless network access device, it is difficult for the mobile terminal to acquire the current network address information of the first wireless network access device. Therefore, before the step S203 mentioned above, before receiving, by the forwarding server, the first authentication packet sent by the second wireless network access device in response to the wireless network access request sent by the mobile terminal, the method further includes: and sending the associated terminal information to an address server for the address server to send the first network address information to the mobile terminal based on the communication identifier.
The address server is a server preset on the public network and used for storing network address information of the wireless network access device. The associated terminal information includes the first network address information and a communication identifier of the mobile terminal corresponding to the associated terminal information, where the communication identifier may be a contact address of the mobile terminal, such as a mobile phone number.
In one embodiment, the address server sends the first network address information to the mobile terminal by means of short message based on the communication identification. After receiving the first network address information, the mobile terminal may store the first network address information in an application program for wireless network connection.
