The flow chart of the public network that Fig. 2 provides for the present invention and another embodiment of the adaptive method of private network；
The structural representation of the public network that Fig. 3 provides for the present invention and private network one embodiment of adaptive device.
Specific embodiment
For making the object, technical solutions and advantages of the present invention become more apparent, below in conjunction with specific embodiment, and reference
Accompanying drawing, the present invention is described in more detail.
It should be noted that the statement of all uses " first " and " second " is for distinguishing two in the embodiment of the present invention
The individual entity of same names non-equal or the parameter of non-equal be not it is seen that " first " " second ", only for the convenience of statement, should
It is interpreted as the restriction to the embodiment of the present invention, subsequent embodiment no longer illustrates one by one to this.
The present invention is directed to when arranging private network and public network at present it is impossible to solve private network congestion and the end being connected to public network simultaneously
End returns the problem of private network, so that solve the above problems simultaneously by way of modification private network broadcast and public network timing are inquired about,
So that all terminals is connected with preference in private network, private network can be overcome simultaneously again excessively to lead to due to connecting terminal
Congestion problems.
Specifically, with reference to shown in Fig. 1, for public network and an embodiment of the adaptive method of private network of present invention offer
Flow chart.Adaptive method includes described public network with private network：
Step 101, when private network is detected congestion occurring, according to default algorithm selected part terminal in private network, and
Disconnect the data cube computation of described selected part terminal；Wherein, described private network refers to dedicated network, and terminal should be priority task
In private network.Described congestion refers to lead because the data volume of the terminal access that connection terminal is excessive or connects is excessive in private network
The situation of inadequate resource occurs in the private network causing, for user terminal, it is slower that congestion shows as data access, or even occurs
Caton phenomenon.Here, selected part terminal refers to, in order to solve congestion problems, reduce the quantity being connected to terminal in private network, and
Specifically need to select how many terminals and selected which terminal, need the situation according to congestion and default algorithm to determine.Example
As：Congestion is more serious, then the terminal quantity that may select is more.
Step 102, changes private network broadcast identification, makes to be provided with the information forbidding accessing private network in described broadcast identification；Its
In, the general principles that terminal connects network are：Network segment constantly can send broadcast singal into fixed area, when terminal detects
During this broadcast singal, can be connected in network according to the information comprising in described broadcast singal.The present invention is in order in congestion
Period, do not have new terminal request and be connected in private network, accordingly, it would be desirable to modification private network broadcast identification, namely in private network broadcast
Middle setting is forbidden accessing the information of private network；And the terminal preparing to connect private network finds that comprise in private network broadcast forbids access private network
Information, then will not access private network, but be linked in public network.So, both do not resulted in the congestion again of private network, made new again
Terminal can be connected in resourceful public network in time.
Step 103, according to the default time cycle, public network sends load query request to private network；Wherein, described default
Time cycle is one reference value of the enquiry frequency of setting previously according to conditions such as the network equipment and Internet Uses,
And this period of time can adjust accordingly according to practical situation.Mostly all only support that inquiry is corresponding based on current core net
Communication modes, so needing public network to send inquiry request to private network, can make private network corresponding, therefore, in existing core net
On the premise of structure, can be more prone to realize using this step, and cost is lower.It is, of course, also possible to by changing core
The setting of net is so that private network active timing query load, and Query Result is fed back in public network.As such, it is possible to save send out
The step sending request, and then improve private network and the adaptive efficiency of public network.
It should be noted that the premise in step 103 both can be step 101 it is also possible to not have precondition.That is,
Public network can be arranged, and timing sends inquiry request always, or, when needing to wait private network to cross congestion when occurring, just start inquiry step
Suddenly.Or, need to judge whether that there is the terminal (such as special-purpose terminal) that should be connected to private network in public network, only work as inspection
Measure when there is special-purpose terminal in public network, just can start query steps.
Step 104, private network receives the load query request that public network sends, and inquires about current offered load；Judge that private network is worked as
Whether front offered load is less than default load threshold；If current offered load is less than default load threshold, execute
Step 105.
Step 105, according to step 104, if current offered load is less than default load threshold, gathers around to public network feedback
Plug releases instruction, and changes private network broadcast identification, makes to be provided with the information that license accesses private network in described broadcast identification；Its
In, described load threshold be one set in advance for judging the reference value whether congestion releases, for example：Internet resources are
100, if the resource that present terminal needs, more than 100, will occur congestion, if the resource that present terminal needs is less than 80,
Represent there is no congestion, and can continue to access new terminal, and when the resource that present terminal needs is between 80-100,
Represent and be in congestion times, now can not access new terminal, otherwise it may happen that congestion.Described offered load is only intended to table
Show the reference standard judging whether network occurs congestion, and according to existing network technical background it is also possible to select other judgements
Standard, therefore, offered load not limitation of the present invention.
Step 106, the congestion that public network receives private network feedback releases instruction, and releases the letter in instruction according to described congestion
Breath, disconnects the terminal of connection, makes terminal reconnect to private network.Wherein, described congestion releases instruction and is intended merely to represent anti-
The information of congestion releasing is comprised, for pointing out public network, the congestion of private network has released in feedback instruction.When congestion occurs, very may be used
The terminal that can have part is connected on public network, and when private network release congestion when, be in connect public network state terminal due to
Can not identify when private network releases congestion, generally will not be actively connected to private network, accordingly, it would be desirable to private network sends congestion solution to public network
Except instruction so that the terminal of connection is disconnected by public network, the broadcast being then based on private network has been changed to license connection, therefore, this
A little terminals will reconnect in private network.
From above-described embodiment, above-mentioned public network and the adaptive method of private network, by when congestion in private network, according to
The terminal of pre-defined algorithm breaking part connection, solves the congestion problems of private network, is then provided with private network broadcast and forbids connecing
Enter the information of private network so that new terminal nor be connected in private network, both ensure that private network will not be due to the access of new terminal
And here sends congestion, and new terminal is directly connected in resourceful public network, substantially increases network connection pipe
The efficiency of reason.Congestion is occurred in that based on private network, then terminal may be had to be connected in public network, so when private network congestion releases
When, need to make terminal (include having connected the terminal of public network and prepare to connect the new terminal of network) be connected in private network, and this
Bright by make public network according to the default time cycle to private network send load query request, private network will be anti-according to Query Result
To public network, if inquiry obtains private network offered load and is less than default load threshold, private network sends congestion solution to public network for feedback instruction
Except instruction, and it is provided with the information of license access private network in broadcast identification so that the new terminal preparing to connect network can connect
It is connected to private network, after public network receives congestion releasing instruction simultaneously, it will according to the information in instruction, release the terminal of connection,
And then terminal is reconnected in private network.Therefore, described public network and the adaptive method of private network can not only effectively solvings
The congestion problems of public network, and release, in private network, the terminal enabling to be in public network during congestion and return to private network.
In some optional embodiments of the present invention, described terminal includes special-purpose terminal and ordinary terminal；Wherein, special end
To in private network, ordinary terminal is linked in public network end priority access all the time.In the network system of the present invention, ordinary terminal is all the time
It is connected to public network, and special-purpose terminal is preferably attached to private network, only when congestion in private network, just have part special-purpose terminal can connect
