Detailed Description
For the purpose of better explaining the present invention and to facilitate understanding, the present invention will be described in detail by way of specific embodiments with reference to the accompanying drawings.
According to the method and the device for directly connecting the mobile terminal with the home cloud server, the DHCP server, the mobile terminal and the storage medium, WiFi Direct connection is established with the mobile terminal when the DHCP service is started after the home cloud server enters a Wi-Fi Direct mode; receiving a network configuration request sent by the mobile terminal, generating a DHCP response message according to the network configuration request, and allocating an IP address to the mobile terminal according to the DHCP response message, wherein the DHCP response message comprises a route filling prohibition option. Therefore, the home cloud server works in a standard Wi-Fi Direct mode, when an IP address is allocated to the mobile terminal, the mobile terminal is not sent with the default route, the default route of the mobile terminal system is reserved, and therefore the mobile terminal does not need to be changed at the bottom layer, and the mobile terminal can be directly connected with the home cloud server and can also normally access the Internet.
In order to better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can 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 invention to those skilled in the art.
Fig. 1 is a flowchart of a method for a mobile terminal to directly connect to a home cloud server according to an embodiment of a first aspect of the present invention, where as shown in fig. 1, the method for the mobile terminal to directly connect to the home cloud server includes the following steps:
s101, when the home cloud server starts the DHCP service after entering a Wi-Fi Direct mode, WiFi Direct connection is established with the mobile terminal.
S102, receiving a network configuration request sent by the mobile terminal, generating a DHCP response message according to the network configuration request, and allocating an IP address to the mobile terminal according to the DHCP response message, wherein the DHCP response message comprises a route filling prohibition option.
It should be noted that Wi-Fi Direct is a standard that allows devices in a wireless network to be connected to each other without passing through a wireless router, and similar to bluetooth technology, the standard allows wireless devices to be connected to each other in a Peer-to-Peer (Peer-to-Peer) manner, and transmission speed and transmission distance are greatly improved compared to bluetooth. The Wi-Fi Direct mode is as follows: compatible devices provide direct wireless connectivity capabilities without having to use the access point of a wireless network router. The Wi-Fi Direct mode has the advantages that the network of the mobile terminal does not need to be changed, unnecessary data traffic is not brought, and the access right does not need to be opened to other equipment on the local network.
Specifically, after the home cloud server is powered on, the home cloud server enters a Wi-Fi Direct mode, after the home cloud server enters the Wi-Fi Direct mode, DHCP service is started, and when the mobile terminal and the home cloud server J establish WIFI Direct connection, the mobile terminal initiates a DHCP request to request network configuration from the home cloud server. The method comprises the steps that a DHCP service of the home cloud service receives a network configuration request and generates a DHCP response message according to the network configuration request, wherein the DHCP response message comprises an IP address and a route filling prohibition option, namely, the DHCP does not fill the route option of the home cloud server when the IP address is allocated, and therefore the DHCP response message does not contain a route IP. The IP address allocated by the DHCP is a network node for the mobile terminal to access the home cloud server, namely, the mobile terminal can access the home cloud server according to the IP address.
The process that the mobile terminal acquires the IP address from the home cloud server is called as a lease process of DHCP, and when the mobile terminal sends a service request to a DHCP service for the first time, the method comprises the following steps: the mobile terminal sends a request IP address to the DHCP service (the home cloud server sends a DHCP Discover broadcast packet); DHCP service response (DHCP service sends DHCP Offer broadcast packet); the mobile terminal selects a gateway address (the mobile terminal sends a DHCP Request broadcast packet); the DHCP service determines the lease (the DHCP service sends a DHCP ACK broadcast packet). Specifically, after the mobile terminal is powered on, at this time, the mobile terminal does not have an IP address, so a legal IP address needs to be obtained through the DHCP service, at this time, the mobile terminal sends DHCP Discover discovery information in a broadcast manner to find the DHCP service, where the broadcast information includes a MAC address and a computer name of the mobile terminal, so that the DHCP service determines which mobile terminal sent the service request. When the DHCP service receives the information of the IP address requested by the mobile terminal, the legal IP address in the DHCP service is searched, and the legal IP address is marked and added into the DHCP Offer message, then the DHCP service broadcasts a DHCP Offer message, and the message comprises: the MAC address of the mobile terminal, the legal gateway address provided by the DHCP service, the subnet mask, the default gateway, the lease time, and the IP address of the DHCP service.
Next, the mobile terminal extracts an IP address from the first DHCP Offer message received and broadcasts a DHCP Request message to all DHCP services indicating that it receives the provided contents, the message including a service identifier (home cloud server IP address) of a server providing an IP configuration for the mobile terminal, the DHCP service checks the home cloud server identifier field to determine whether the provided IP address is accepted, and if the DHCP Offer is rejected, the DHCP service cancels and retains the IP address to provide a Request for a next IP address lease. After receiving the DHCP Request message, the DHCP service broadcasts a success confirmation to the mobile terminal in the form of a DHCP ACK message, the message contains effective lease of the IP address and other configurable information, and when the mobile terminal receives the DHCP ACK message, the IP gateway address is configured to complete the initialization of TCP/IP.
When the mobile terminal logs in again each time, the mobile terminal does not need to send DHCP Discover information, but directly sends DHCP Request information containing the IP address allocated last time, and after the DHCP service receives the information, the mobile terminal can send response information to enable the mobile terminal to continue using the original gateway address and answer a DHCP ACK confirmation message.
That is to say, when the home cloud server starts the DHCP service after entering the Wi-Fi Direct mode, after the WIFI Direct connection is established between the mobile terminal and the home cloud server, the mobile terminal sends a network configuration request to the home cloud server, and the DHCP service generates a response message according to the network configuration request, prohibits filling of routing options, that is, does not allocate a routing address (gateway IP address), and only requests other configuration information (lease term, gateway, DNS server, etc.). For example, by modifying the DHCP service, the Rout (3) option is not filled in the DHCP service message sent by the DHCP service. For example, the format of the DHCP message sent by the DHCP service is roughly as follows:
Bootstrap Protocol (ACK)
Message type: Boot Reply (2)
Hardware type: Ethernet (0x01)
Hardware address length: 6
Hops: 0
……
Magic cookie: DHCP
Option: (53) DHCP Message Type (ACK)
Option: (54) DHCP Server Identifier
Option: (51) IP Address Lease Time
Option: (1) Subnet Mask
option (3) Router = > avoid filling the Option (Option) by modifying DHCP service configuration or source code
Option: (6) Domain Name Server
Option: (255) End
Padding: 00000000000000000000000000000000000000000000
More specifically, when the DHCP service receives a network configuration request of the mobile terminal, a DHCP response message is generated, and the response message does not include a routing IP address, so that when the home cloud server responds to a direct connection request of the mobile terminal, and the home cloud server allocates an IP address (node IP address) to the mobile terminal, a default route is not issued to the mobile terminal (the routing address generated by the DHCP service, and since there is no routing address in the service message, the home cloud server does not issue a routing address to the mobile terminal, so that the mobile terminal retains its own routing address). Therefore, the mobile terminal can access the home cloud server through the IP address and can access the external network through the routing address of the mobile terminal, such as WeChat, QQ, a browser and the like, so that the mobile terminal can access the home cloud server and the external network.
Therefore, the home cloud server works in a standard Wi-Fi Direct mode, when an IP address is allocated to the mobile terminal, the mobile terminal is not sent with the default route, the default route of the mobile terminal system is reserved, and therefore the mobile terminal does not need to change the bottom layer, and the mobile terminal can be directly connected with the home cloud server and can also normally access the Internet.
It should be noted that the home cloud server is a private network, and not a public network, so when the mobile terminal sends the direct connection request, a node IP address is sent, which indicates that the current mobile terminal is in the private network of the home cloud server, and data transmission and interaction can be realized in the private network without leakage. For example, a family member connected to a family cloud server may share a family image or the like within the private network.
As a specific example, as shown in fig. 2, when a home cloud server enters a Wi-Fi Direct mode and starts a DHCP service, if a mobile terminal accesses the home cloud server, first determining identification information of the home cloud server, for example, SN (Serial Number) information, after determining the identification information of the home cloud server, the mobile terminal establishes WIFI Direct connection with the home cloud server, the mobile terminal initiates a DHCP request to send a network configuration request to the home cloud server, and the DHCP service of the home cloud server generates a DHCP response packet according to the network configuration request and sends the DHCP response packet to the mobile terminal, where the response packet includes an IP address but does not include a default routing address. And the mobile terminal receives the node IP address distributed by the home cloud server, and when the mobile terminal is connected with the home cloud server according to the node IP address, the mobile terminal reserves the original default routing address of the system as the default routing address does not exist in the service message.
It should be noted that the manner in which the mobile terminal obtains the identifier of the home cloud server differs according to different usage scenarios. For example, when the mobile terminal scans and binds a two-dimensional code of a home cloud server, the two-dimensional code includes an identifier of the home cloud server, and the identifier of the corresponding home cloud server can be obtained by continuously analyzing the two-dimensional code. For another example, in the use process after the mobile terminal binds the home cloud server, an APP (Application) corresponding to the home cloud server on the mobile terminal may be information on the bound home cloud server.
In an embodiment of the present invention, an operating system of a current mobile terminal mainly includes an Android system and an ios system. When the operating system of the mobile terminal is an Android system, the mobile terminal is connected to the home cloud server in a Wi-Fi Direct mode through the WifiP2 pManager. When the operating system of the mobile terminal is an ios system, the mobile terminal is connected to the home cloud server in a station mode.
Specifically, the Wi-Fi Direct realized by the Android system is compatible with a standard protocol, so that the Wi-Fi Direct can be directly connected to a home cloud server through a WifiP2pManager in a Wi-Fi Direct mode, and an active connection mode or a passive connection mode can be adopted. The active connection mode is that the mobile terminal actively sends a Probe request frame on each channel to request the home cloud server to respond, so that whether the home cloud server exists or not is known, and when the home cloud server receives the Probe request, the home cloud server responds with a Probe response. The passive connection mode is that the mobile terminal is in a receiving state, receives beacon frames sent by the home server, switches among different channels, monitors the beacon frames in the air, the beacon comprises various parameters required by adding a certain home cloud server, and the beacon is displayed in a list to be connected after being received by the mobile terminal.
In a list to be connected, a user outputs a password on the mobile terminal for identity authentication, the mobile terminal sends an authentication request, the request comprises an algorithm number and a frame sequence number 1, after a home cloud server receives a first frame, the home cloud server processes and replies, and the reply frame comprises an algorithm number 2, a state code 0 and a challenge instruction. And the mobile terminal replies a third frame to a second frame carrying the challenge instruction, wherein the frame comprises the algorithm number, the sequence number is 3 and the challenge instruction, and except for the header, the mobile terminal performs WEP encryption processing on the information and then sends the information. After the home cloud server receives the third frame, a decryption process is performed, integrity is checked, the challenge password is solved, and the integrity check is passed. After the verification, the mobile terminal is proved to have set the WEP key required by joining the network, and then the fourth frame is replied, which comprises the algorithm number, the sequence number of 4 and the status code of 0. After the identity authentication is completed, the terminal equipment can be connected with the family cloud server to perform data interaction and other operations.
When the mobile terminal is an ios system, the wireless access is not accepted due to the characteristics of the ios system, but the mobile terminal can be connected to the home cloud server, and at this time, the mobile terminal can be connected to the home cloud server in a station mode. For example, a hot spot of the mobile terminal is opened, a home cloud server which can be connected around is scanned, and a direct connection request is sent according to an identifier of the home cloud server to be connected. The home cloud server enters a Wi-Fi Direct mode after receiving the Direct connection request, the DHCP service generates a DHCP service message according to the Direct connection request, and when an IP address is allocated to the mobile terminal, the home cloud server prohibits issuing of a default route to the mobile terminal.
Therefore, the original default routing address of the mobile terminal can be reserved no matter the mobile terminal is an Android system or an ios system, and the mobile terminal can also normally access the Internet while being successfully connected with the home cloud server.
In summary, in the method for directly connecting the mobile terminal to the home cloud server according to the embodiment of the present invention, when the home cloud server starts the DHCP service after entering the Wi-Fi Direct mode, WiFi Direct connection is established with the mobile terminal; receiving a network configuration request sent by the mobile terminal, generating a DHCP response message according to the network configuration request, and allocating an IP address to the mobile terminal according to the DHCP response message, wherein the DHCP response message comprises a route filling prohibition option. Therefore, the home cloud server works in a standard Wi-Fi Direct mode, when an IP address is allocated to the mobile terminal, the mobile terminal is not sent with the default route, the default route of the mobile terminal system is reserved, and therefore the mobile terminal does not need to be changed at the bottom layer, and the mobile terminal can be directly connected with the home cloud server and can also normally access the Internet.
The embodiment of the second aspect of the invention also provides a method for directly connecting the mobile terminal with the home cloud server.

s301, when the home cloud server enters a Wi-Fi Direct mode and starts a DHCP service, WiFi Direct connection with the home cloud server is established.
And S302, sending a network configuration request to the home cloud server, wherein the network configuration request is used for indicating that the home cloud server forbids to modify the default route of the mobile terminal when generating the DHCP response message.
And S303, receiving a DHCP response message sent by the home cloud server, and reserving an original default route when IP address allocation is carried out according to the DHCP response message.
According to one embodiment of the invention, the DHCP response message includes the IP address and the DHCP service prohibits populating the routing option when assigning the IP address.
According to one embodiment of the invention, when the operating system of the mobile terminal is an Android system, the mobile terminal is connected to the home cloud server in a Wi-Fi Direct mode through a WifiP2 pManager.
According to one embodiment of the invention, when the operating system of the mobile terminal is an ios system, the mobile terminal is connected to the home cloud server in a station mode.
