Fig. 1 is the schematic flow sheet of a kind of domain name system DNS processing method that the embodiment of the present invention provides, below in conjunction with
A kind of domain name system DNS processing method the embodiment of the present invention is described in detail by accompanying drawing 1 from terminal equipment side, the method
Comprise the following steps S101-step S103.
Step S101: in the case of access network terminal unit being detected switches, initiates the DNS of target domain name
Inquiry request.
Specifically, the associative processor in terminal unit or terminal unit or related process module, (follow-up identical not
Repeat again) in the case of access network terminal unit being detected switches, the DNS query initiating target domain name is asked, and
DNS query is asked, and is i.e. directed to corresponding dns server and initiates query statement, comprises the parsing of this target domain name with acquisition
The dns resolution result of IP address.And before access network switching represents the network that currently accessed of terminal unit and switches
Access network different, the switching between Wireless Fidelity Wi-Fi network and mobile data network, different mobile data can be included
Switching between network, the switching between different Wi-Fi network, the switching etc. between cable network and wireless network, such as use
Family is the mobile data network of use after family uses Wi-Fi network to be switched to go out.
It should be noted that occur network switching time or afterwards, terminal unit initiate target domain name DNS query please
Asking (the IP address that requesting query is corresponding), this target domain name can be the appointment DNS list that user is stored in advance in terminal unit
In, such as, user use the domain name of a class website that frequency is the highest or application be placed in this DNS list；Can also be
The domain name of all visited website in subscriber terminal equipment is placed in the list, also or some IP address change relatively
For domain name frequently, this is not especially limited by the present invention.It is understood that due in the prior art, network does not occurs
In the case of switching, repeatedly accessing same website (such as target domain name), general ip address will not change, therefore
As long as saving the IP address of correspondence when of access for the first time, then can be after accessing for the first time, it is right directly to use
The IP address answered, it is not necessary to again inquire about, but in some cases, the situation that the access network of such as terminal unit switches
Under, the IP address that may result in preservation can be invalid, and user cannot normally access, and therefore the embodiment of the present invention can be by sending out
During raw access network switching, the most again or in advance obtain the up-to-date IP address that target domain name is corresponding, access to avoid user to need
When, it may appear that access failed situation.
Step S102: receive the dns resolution result that the request of described DNS query is corresponding, described dns resolution result include to
A few IP address corresponding with described target domain name.
Specifically, dns resolution result is fed back to terminal unit by the dns server receiving DNS query request, and DNS solves
Analysis result includes that at least one IP address corresponding with described target domain name, reason are that the website of some domain name may
Corresponding multiple servers, it is possible to there is multiple IP address, included at least one and mesh in the dns resolution result therefore fed back
The IP address that mark domain name is corresponding.In concrete application scenarios, such as, terminal unit is usually to use to its detailed process
Smart mobile phone, opens browser, inputs a domain name, such as inputs www.163.com, and at this moment, the smart mobile phone of use can be sent out
Going out a DNS request to local dns server, local dns server is typically all the network access server business of smart mobile phone
There is provided, such as China Telecom, China Mobile；After the DNS request of inquiry www.163.com arrives local dns server, local
First dns server can inquire about its caching record, if there being this record in Huan Cun, it is possible to do not have if directly returning result
Having, local dns server also to be inquired about to DNS root server, and root dns server does not record concrete domain name and IP ground
The corresponding relation of location, but tell local dns server, can go to continue inquiry on domain server, and provide domain server
Address.Local dns server continues to send request to domain server.Finally, local dns server is to the analysis service of domain name
Device sends request, the most just can receive a domain name and IP address corresponding relation, and local dns server not only to return IP address
Back to the smart mobile phone of user, also this corresponding relation is preserved in the buffer, during in case next other user inquires about, permissible
Directly return result, accelerate network and access.Smart mobile phone receives this IP address and can be saved in the caching of mobile phone simultaneously, in order to
Access next time and need not access local dns server (see step S103).
Step S103: a described IP address is stored in described terminal unit.
Specifically, an IP address corresponding for the described target domain name of inquiry acquisition is stored in described terminal unit.
Although now user does not the most access target domain name, i.e. terminal unit and is also not received by referring to for the access of this target domain name
Order, but, in the embodiment of the present invention, can be by advance by corresponding for target domain name (such as user it is frequently necessary to the website accessed)
IP address store, then when user need access when, it is possible to directly use, it is not necessary to again wait user send access
The when of instruction, just go to obtain IP address, cause the response time of user to be greatly increased, but if carry out inquiry storage in advance
If, when user is actual conduct interviews time, then can avoid temporary needs inquiry consume time, accelerate user enter website
Speed.
The embodiment of the present invention, in the case of switching in access network terminal unit being detected, initiates target
The DNS query request of domain name, and receive the dns resolution result that DNS query request is corresponding, dns resolution result the most at last includes
At least one IP address corresponding with target domain name is stored in terminal unit.The i.e. access network at terminal unit occurs
Cut change in the case of IP address corresponding to target domain name that may be present when can produce change, access this user in advance
Before the network that target domain name is corresponding, obtain and store the IP address that this target domain name is corresponding, in order to user accesses at needs
During this target domain name, can directly access the IP address of this storage, and obtain without interim, accelerate the net that target domain name is corresponding
The success rate of the access of network and speed, the network promoting user is experienced.
Fig. 2 is the schematic flow sheet of the another kind of domain name system DNS processing method that the embodiment of the present invention provides, below will knot
Close accompanying drawing 2 from terminal equipment side, the another kind of domain name system DNS processing method the embodiment of the present invention to be described in detail, as
Shown in Fig. 2, the method may comprise steps of S201-step S207.
Step S201: before described access network terminal unit being detected switches, deposit in described terminal unit
Contain the 2nd IP address that described target domain name is corresponding.
Specifically, before the access network at embodiment of the present invention indication switches, it is assumed that for target domain name, before
There is the record accessing this target domain name, then after accessing this target domain name before, the 2nd IP ground just inquiry obtained
Location stores, in order to follow-up access again before this switching network time, directly access this 2nd IP address, certain premise is
2nd IP address has not expired, and the most before the deadline, this effect duration can be that user is arranged based on experience value, it is also possible to
It is that related application itself excavates the rational time value arranged according to mass data.As it is shown on figure 3, Fig. 3 is the embodiment of the present invention
The concrete application scenarios schematic diagram of the domain name system DNS processing method provided, in Fig. 3, such as when user is away from home, use
It is the website 11 (on the left of Fig. 3) of mobile data network access, but needs the access network of terminal unit afterwards in going back home
Switch to Wi-Fi network (scheming right left side), now when using mobile data network, use second in this method step
Network corresponding to target domain name that IP address accesses, when using Wi-Fi, is then to use the 2nd IP address to access target domain name pair
The network answered.
Step S202: in the case of access network terminal unit being detected switches, initiates the DNS of target domain name
Inquiry request.
Step S203: receive the dns resolution result that the request of described DNS query is corresponding, described dns resolution result include to
A few IP address corresponding with described target domain name.
Step S204: a described IP address is stored in described terminal unit.
Specifically, step S202 to step S204 refers to step S101 in above-mentioned Fig. 1 embodiment to step S103, this
In repeat no more.
Step S205: when receiving the access instruction for described target domain name, accesses and is stored in described terminal unit
In network site corresponding to a described IP address.
Specifically, when receiving the access instruction of target domain name, then can directly access and be stored in terminal unit
The network site that oneth IP address is corresponding, without the interim DNS query request initiating target domain name, therefore can save significantly
Save user and enter time of related web site, promote user and surf the Net experience.
Step S206: if accessing the network site failure that a described IP address is corresponding, then access described 2nd IP address
Corresponding network site.
Specifically, if access network site failure corresponding to an IP address, then likely this network site pair is shown
The server answered temporarily does not provides service or occurs in that fault, temporarily cannot be successfully connected, it is thus possible to need to access other
The IP address that server is corresponding, i.e. can access and have the access successful 2nd IP address of target domain name before.
Step S207: if accessing the network site failure that described 2nd IP address is corresponding, then send to described terminal unit
The dns resolution result late note of described target domain name, to point out described terminal unit to carry out the IP that described target domain name is corresponding
The renewal of address.
Specifically, the 2nd IP address is the IP address occurring to store before network switching, namely before network switches
Under access network, access IP address corresponding to target domain name, if network site corresponding to this IP address also accesses failed, explanation
An IP address and the 2nd IP address that target domain name is corresponding all fail, and need again to inquire about acquisition, it is therefore desirable to terminal
Equipment sends the dns resolution result late note of target domain name, and prompt terminal equipment carries out the IP address that this target domain name is corresponding
Renewal, in order to follow-up when again access this target domain name, can directly carry out the access of corresponding IP address, and
Can access successfully.As shown in Figure 4, the another kind of the domain name system DNS processing method that Fig. 4 is provided by the embodiment of the present invention is concrete
Application scenarios schematic diagram, in Fig. 4, after there is network switching (mobile data network switches to Wi-Fi network), now may
Depositing an IP address and situation that the 2nd IP address all cannot access, now terminal unit sends and accesses failed prompting, and
The DNS query request of target domain name is re-started, in order to can be with network corresponding to this target domain name of successful access on backstage.
The embodiment of the present invention, in the case of switching in access network terminal unit being detected, initiates target
The DNS query request of domain name, and receive the dns resolution result that DNS query request is corresponding, dns resolution result the most at last includes
At least one IP address corresponding with target domain name is stored in terminal unit.The i.e. access network at terminal unit occurs
Cut change in the case of IP address corresponding to target domain name that may be present when can produce change, access this user in advance
Before the network that target domain name is corresponding, obtain and store the IP address that this target domain name is corresponding, in order to user accesses at needs
During this target domain name, can directly access the IP address of this storage, and obtain without interim, accelerate the net that target domain name is corresponding
The success rate of the access of network and speed, the network promoting user is experienced.
