Embodiment
Be elaborated below in conjunction with the drawings and specific embodiments.
The embodiment of the invention provides a kind of access method of wireless router, as shown in Figure 1, may further comprise the steps:
Step s101 receives the request of user terminal access service end wireless router domain name;
Step s102 inquires about the service end wireless router of this domain name correspondence;
Step s103 sends the note request to the service end wireless router;
Step s104 receives the service end wireless router according to the note request, sends the IP address of domain name corresponding server with note;
Step s105 sends the IP address to user terminal, makes user terminal according to the visit of above-mentioned IP address realization to the service end wireless router.
By the method that the embodiment of the invention provides, the user can obtain the IP address of the domain name correspondence of wireless router by note, realizes the visit to the service end wireless router; By the query function of note, do not have in the opposite end under the situation of online, activate the other side's online, make things convenient for user access.
Below in conjunction with concrete application scenarios the embodiment of the invention is further specified, wherein, user terminal is an example with PC PC, and the service that wireless router provides can be FTP, WEB or mail service, is example with the FTP service below.
The embodiment of the invention provides a kind of access method of wireless router, is applied to comprise in the system of PC, application end wireless router A, service end wireless router B and FTP service, as shown in Figure 2, may further comprise the steps:
Step s201, PC send domain name request to application end wireless router A;
PC is by the domain name request FTP service of ftp server under the service end wireless router B, because the IP address dynamic change of this ftp server, so do not have fixing corresponding relation between the domain name of this server and IP address.The domain name request of PC at first sends to A.
Step s202, application end wireless router A receives and handles the domain name request that above-mentioned PC sends;
A receives the domain name request that above-mentioned PC sends, if A does not also dial up on the telephone, then at first the Internet connection is set up in dialing.Comprise domain name tabulation among the A, store the domain name of server and the telephone number of the router corresponding with this server; A receives after the domain name request that PC sends, and detects this domain name whether in the domain name tabulation, if inquire about the service end wireless router corresponding with this domain name, execution in step s203; If not the request of then refusing PC.
Step s203, application end wireless router A sends the message search request to service end wireless router B;
When the domain name of the ftp server that detects PC request is in the domain name tabulation, comprise the short message receiving-transmitting device among the A, can send note to B by the telephone number of B, whether inquiry B surfs the Net.
Step s204, the query requests of service end wireless router B response application end wireless router A;
Also comprise the short message receiving-transmitting device among the B, can carry out short message interacting with A, receive the message search request that A sends, answer short message sends to A to current network state.
Step s205, application end wireless router A sends the note order to service end wireless router B;
After A received the state information of B transmission, if not online of B, A sent order to B and notifies B to connect online, and requires B to report the IP address of domain name corresponding server;
If B surfs the Net, then A directly requires B to report the IP address of server.
The domain name tabulation also is used to store the IP address corresponding with domain name among the A; After A found B according to domain name, the IP address of this domain name correspondence whether among this domain name tabulation of inquiry earlier if having, was then notified the B online and this IP address is sent to PC.If PC illustrates promptly that according to serv-fail under this IP address visit B the IP address of this domain name correspondence changes, then A requires the B online and reports current IP address.
Step s206, the note order that service end wireless router B response application end wireless router A sends;
After B receives the note that A sends, at first detect A whether in trust list.If detect A in trust list, and can carry out this order, then dial up on the telephone, simultaneously the IP address of the ftp server that B is obtained with note sends to A; If detect A not in trust list,, then refuse the requirement of A though perhaps A cannot carry out this order in trust list.
Step s207, application end wireless router A receive the note response of service end wireless router B;
After A receives the IP address information of B transmission, upgrade the corresponding relation of dynamic IP and domain name, obtain the IP address corresponding with domain name request.And after obtaining the IP address corresponding with domain name request, A sends this IP address to PC.
Step s208, PC serves according to the FTP under the corresponding IP address access services end wireless router B.
By the method that adopts the embodiment of the invention to provide, can support a router-A, B to be used as peer device fully manages, the user can manage the wireless device of far-end by note, realize peer access, do not have in the opposite end under the situation of online, activate the other side's online, the domain name system of management at any time oneself by note, do not need to apply for domain name, easy to use.
