Detailed description of the invention
For making the purpose of embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in embodiment of the present invention, technical scheme in embodiment of the present invention is clearly and completely described, obviously, described embodiment is a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
The method flow diagram that the IP address that Fig. 1 is the application embodiment a kind of terminal unit of offer is re-rented.The flow process frame diagram that the IP address of a kind of terminal unit that Fig. 2 provides for the application embodiment is re-rented.Although multiple operations that flow process include with particular order occur are described below, it should be appreciated that understand, these processes can include more or less of operation, and these operations can sequentially perform or executed in parallel (such as using parallel processor or multi-thread environment).As it is shown in figure 1, described method may comprise steps of.
Step S1: when described terminal unit is connected with the foundation of default access point, described default access point inquires about the lease time limit of IP address and the described IP address being associated with described terminal unit, and the described lease time limit is corresponding with lease duration.
In the present embodiment, described terminal unit can be the electronic equipment that smart mobile phone, panel computer, computer (including notebook computer, desktop computer), personal digital assistant or intelligence wearable device etc. can connect network.Described default access point such as can provide the equipment of network insertion for router, gateway, bridge etc..
In the present embodiment, described default access point can preserve the record setting up the terminal unit being connected with it.Described record can be stored by the form of key-value pair (key-value).In described key-value pair, the mark of described terminal unit can as key (key), and the mark of described terminal unit can be such as the MAC Address of described terminal unit, and the mark of described terminal unit can uniquely determine this terminal unit.Described default access point is previously allocated to the IP address information of described terminal unit can as the value (value) being associated with the mark of described terminal unit, and described IP address information can include IP address and lease time limit corresponding to described IP address.So, when described terminal unit is connected with the foundation of described default access point, described default access point just can inquire the IP address being associated with described terminal unit and the lease time limit of described IP address according to the MAC of described terminal unit.Wherein, the described lease time limit is corresponding with lease duration.Such as, the described lease time limit is on April 29,0: 00 o'clock on the 28th 0 minute to 2016 April in 2016, then lease duration corresponding to described lease time limit can be 24 hours.It is to say, the described lease time limit can be limited by initial time and deadline.Duration between described initial time and described deadline just can be described lease duration.
In the present embodiment, when described terminal unit is connected with the foundation of described default access point, it is possible to from presetting access point transmission DHCP request message described in trend, to ask described default access point for its distribution IP address.After described default access point receives described DHCP request message, it is possible to extract the MAC Address of described terminal unit from described DHCP request message.So, according to described MAC Address, described default access point just can inquire about the IP address being associated with described MAC Address and the lease time limit of described IP address.Specifically, described default access point using described MAC Address as key, and can inquire about the key-value pair comprising described key.So inquire about the lease time limit that the value comprised in the key-value pair obtained just can be IP address and the described IP address being associated with described MAC Address.
Step S2: when the described lease time limit is out of date, described default access point is that described terminal unit redistributes current IP address, and is that described current IP address distributes the current lease time limit corresponding with described lease duration.
In the present embodiment, after inquiring the lease time limit being associated with described terminal unit, just may determine that whether this lease time limit is expired.In the present embodiment, it is possible to described lease time limit and current system time are compared, when the deadline in described lease time limit is before described present system time, it is possible to determine that the described lease time limit is out of date；If after described present system time, then can be determined that the deadline in described lease time limit, the described lease time limit is not out of date.
In the present embodiment, when the described lease time limit is out of date, described default access point needs to redistribute current IP address for described terminal unit, so that described terminal unit can normally access network.After being assigned with current IP address for described terminal unit, described default access point also needs to distribute the current lease time limit into described current IP address, to limit the useful life of described current IP address.In the present embodiment, described default access point using the lease duration corresponding described lease time limit of inquiring as current lease duration, and can set up the current lease time limit according to described current lease duration.Such as, last and the described default access point of described terminal unit is set up when being connected, described default access point is that it is assigned with the lease time limit that lease duration is 24 hours, so after this is set up and connects, the lease the duration corresponding current lease time limit still can be set to 24 hours by described default access point.
In the present embodiment, when the described lease time limit is out of date, described default access point can obtain free IP addresses, it is possible to the IP address being associated with described MAC Address is revised as described free IP addresses.So just described free IP addresses can be distributed to described terminal unit as described current IP address.Follow-up described default access point just can be the current lease time limit that the distribution of described free IP addresses is corresponding with described lease duration.
Step S3: described default access point obtains re-renting duration according to described lease duration calculation, and for the distribution of described current IP address with described re-rent duration corresponding re-rent the time limit, wherein, described in re-rent duration more than described lease duration.
In the present embodiment, in order to avoid the described lease time limit expire after described current IP address be retracted, described default access point can obtain re-renting duration according to described lease duration calculation, and for the distribution of described current IP address with described re-rent duration corresponding re-rent the time limit.So, after the described lease time limit expires, described terminal unit can be continuing with described current IP address described re-renting in the time limit, such that it is able to avoid described default access point to carry out the distribution of IP address continually.
In the present embodiment, set up for the terminal unit that is connected for frequent and described default access point, it is possible to re-rent the time limit for its distribution longer time limit.Therefore, in the present embodiment, described in re-rent re-renting duration and can increasing preset duration on the basis of described lease duration of time limit so that described in re-rent duration more than described lease duration.Specifically, described default access point can obtain re-renting duration according to described lease duration calculation according to the following equation:
R=P+24
Wherein, R be described in re-rent duration, unit is hour；P is described lease duration, and unit is hour.
Therefore, in present embodiment re-rent duration all the time can more than lease duration 24 little time, so, it is assumed that this is set up described terminal unit when connecting and uses the lease duration of described current IP address to be 24 hours, then the duration of re-renting of its correspondence just can be 48 hours.If this terminal unit connects described default access point incessantly always, then what this terminal unit was follow-up re-rent duration then constantly can increase with the speed of each 24 hours.So, for the terminal unit of the described default access point of fixing connection, over time, become, the re-renting duration and will be far longer than 24 hours of its correspondence, thus it can use fixing IP address always, it is not necessary to described default access point is redistributed.
Refer to Fig. 2, in the application one embodiment, when described default access point is when attempting the lease time limit inquiring about IP address and the described IP address being associated with described terminal unit, discovery cannot obtain Query Result, then then illustrates between this terminal unit with described default access point it is first connection.In this case, described default access point can choose a free IP addresses, and described free IP addresses is distributed to described terminal unit, thus being described terminal unit distribution current IP address.After being assigned with current IP address, described default access point can be the current lease time limit that the distribution of described current IP address is corresponding with presetting lease duration.In the present embodiment, described default lease duration can be such as 24 hours.After being provided with the lease time limit for described current IP address, described default access point is equally possible obtains re-renting duration according to described default lease duration calculation, and for the distribution of described current IP address with described re-rent duration corresponding re-rent the time limit.Wherein, described in re-rent duration equally possible more than described default lease duration, the formula of calculating can also be identical with above-mentioned formula.
So, when described terminal unit is connected for the first time with described default access point, except can as the useful life distributing IP address and assigned I P address in the prior art for this terminal unit, in the present embodiment can also assigned I P address re-rent the time limit, with avoid the lease time limit to described in after date preset access point again redistribute IP address for described terminal unit.
In another embodiment of the application, when the lease time limit of the described IP address inquired is not out of date, then illustrate that now described terminal unit still can use described IP address.So, described default access point is just without for the new IP address of described terminal unit distribution, and described IP address only can be defined as the current IP address of described terminal unit, and the described lease time limit is defined as the lease time limit of described current IP address.So, described terminal unit just can continue to use current IP address and lease time limit, is directly accessed in network.
In the present embodiment, after by described terminal equipment access network, whether described default access point can also be inquired about described current IP address and exist and re-rent the time limit.When described current IP address is absent from re-renting the time limit, described default access point can obtain re-renting duration according to the lease duration calculation corresponding with the described lease time limit, and for described current IP address distribution with described re-rent duration corresponding re-rent the time limit, wherein, duration is re-rented described in more than described lease duration.So, when this lease time limit of described terminal unit is to after date, it is possible to continue to rent current IP address, it is not necessary to be reallocated IP address.
