Art is unnecessary fuzzy to avoid causing the present invention.
The application scenarios of the embodiment of the present invention can be Internet of Things or other networks, not limit herein.Fig. 1
The flow chart of suppressing method for the signaling storm in one embodiment of the invention, the suppressing method of signaling storm as shown in Figure 1
Including step 101- steps 104.
In a step 101, the scheduling request that user terminal is sent is received, and the access of user terminal is obtained from scheduling request
Point title.
Wherein, the executive agent in the embodiment of the present invention can be core net in mobile management functional unit (MME,
Mobility Management Entity).It should be noted that scheduling request includes attach request (Attach
Request), public data network connection request (Public Data Network Connectivity Request) and business please
Ask one or more in (Service Request).MME is in the scheduling request for receiving user terminal transmission, Neng Goucong
The access point name (APN, Access Point Name) of user terminal is got in scheduling request.MME can be according to user's end
The access point name at end distinguishes the business that different user terminals are responsible for, for example, the business of user terminal A is radio meter register industry
Business, the business of user terminal B is bank transfer business, the access point name of user terminal A and the access point name of user terminal B
It is different.
In a step 102, the pre- of strategy is inhibited with signaling according to the access point name of user terminal and access point name
If correspondence, obtain target signaling and inhibit strategy.
Wherein, the default corresponding pass that signaling inhibits strategy and access point name to inhibit strategy with signaling is stored in MME
System.That is, diverse access point title, which can be corresponding with different signalings, inhibits strategy.Due to connecing for different user terminals
Access point title is different, and the business of different user terminals can be different, therefore the corresponding business of different access point name may not be used yet
Together, according to the requirement of different business, different signalings can be formulated and inhibit strategy.It is in Access Point Name that target signaling, which inhibits strategy,
Claim in the default correspondence tactful with signaling inhibition, signaling corresponding with the access point name of user terminal inhibits strategy.Letter
It enables and strategy is inhibited to include unit interval scheduling request threshold value and scheduling request braking measure.Wherein, unit interval scheduling request threshold
Value can be with to determine whether need the scheduling request sent out to the user terminal to inhibit.Scheduling request braking measure is used for
It indicates how to inhibit the scheduling request that user terminal is sent out.Since scheduling request includes attach request, public data network
It is one or more in connection request and service request.Corresponding, unit interval scheduling request threshold value is adhered to including the unit interval
It asks one or more in threshold value, unit interval public data network connection request threshold value and unit interval service request threshold value.
In step 103, judge whether quantity of the scheduling request of user terminal transmission within the unit interval is more than target
Signaling inhibits the unit interval scheduling request threshold value in strategy.
Wherein, whether unit interval scheduling request threshold value is to divide to need to carry out the scheduling request that the user terminal is sent out
The boundary of inhibition.Inhibit in strategy if quantity of the scheduling request that user terminal is sent within the unit interval is more than target signaling
Unit interval scheduling request threshold value then shows that network internal may generate signaling storm, network congestion occurs, therefore EMM is needed
The scheduling request to be sent to user terminal inhibits.If quantity of the scheduling request that user terminal is sent within the unit interval
The unit interval scheduling request threshold value being less than during target signaling inhibits tactful, then show that network internal will not generate signaling wind
Cruelly, network congestion will not occur, therefore EMM does not need to inhibit the scheduling request that user terminal is sent.
At step 104, if quantity of the scheduling request of user terminal transmission within the unit interval presses down more than target signaling
Unit interval scheduling request threshold value in system strategy then inhibits the scheduling request braking measure in strategy according to target signaling, right
The scheduling request that user terminal is sent is inhibited.
Wherein, target signaling inhibits strategy corresponding with the access point name of user terminal, if the signaling that user terminal is sent
It is more than the unit interval scheduling request threshold value during target signaling inhibits tactful to ask the quantity within the unit interval, then using advance
The target signaling of setting inhibits the scheduling request measure in strategy, and the scheduling request to be sent to user terminal inhibits, makes
The scheduling request number that is sent within the unit interval of user terminal reduce or user terminal is forbidden to continue to send signaling please
It asks.If quantity of the scheduling request that user terminal is sent within the unit interval is not above the unit during target signaling inhibits tactful
Time scheduling request threshold value then normally receives the scheduling request of user terminal transmission, the scheduling request not sent to user terminal
Inhibited.
A kind of suppressing method of signaling storm provided in an embodiment of the present invention can inhibit according to access point name and signaling
The default correspondence of strategy asks threshold to the different corresponding user terminals of access point name using the different unit interval
Value, judges whether to need to inhibit the scheduling request that user terminal is sent, moreover, in the letter for needing to send user terminal
It enables in the case of asking to be inhibited, the scheduling request of the different corresponding user terminals of access point name can be taken different
Scheduling request braking measure.The business that the corresponding user terminal of different access point name performs is different, different to performing business
User terminal different signaling is taken to inhibit strategy, strategy can be inhibited by setting signaling, to set to user terminal
The inhibition level of scheduling request that business needs are sent, can ensure that important service is not suppressed or inhibition level is smaller, so as to
Improve the reliability that business performs in Internet of Things.
Fig. 2 is the flow chart of the suppressing method of the signaling storm in another embodiment of the present invention, the step 101- steps in Fig. 2
Rapid 104 is essentially identical with the step 101- steps 104 in Fig. 1.The difference lies in the inhibition sides of signaling storm shown in Fig. 2
Method further includes step 105- steps 107.
In step 105, all access point name in current network are obtained.
Wherein, at least one user terminal access current network, therefore at least one can be got from current network
A access point name.
In step 106, it according to the priority of the corresponding business of each access point name, is formulated for each access point name
Signaling inhibits strategy.
Wherein, since different user terminals can correspond to different business, different user terminals correspond to different Access Point Names
Claim, formulating signaling for each access point name inhibits strategy, you can formulates different signalings for different business and inhibits strategy.No
It can be that unit interval scheduling request threshold value is different or scheduling request braking measure is different that same signaling, which inhibits strategy,.
For example, the Access Point Name of user terminal A is known as apn1, then inhibit the unit interval attachment in strategy please for the apn1 signalings formulated
Threshold value is sought as b1, unit interval public data network connection request threshold value is c1, and unit interval service request threshold value is d1；User is whole
The Access Point Name of end B is known as apn2, then it is b2 to inhibit the unit interval attach request threshold value in strategy for the apn2 signalings formulated,
Unit interval public data network connection request threshold value is c2, and unit interval service request threshold value is d2；Wherein, the unit interval adheres to
Ask threshold value b1 can be different from unit interval attach request threshold value b2, unit interval public data network connection request threshold value c1 and
Unit interval public data network connection request threshold value c2 can be different, unit interval service request threshold value d1 and unit interval business
Ask threshold value d2 different.
In step 107, the default correspondence that access point name inhibits strategy with signaling is established.
After formulating corresponding signaling inhibition strategy for each access point name, each access point name and the letter formulated are established
Enable inhibit strategy default correspondence, convenient for carry out signaling storm process of inhibition in, according to the access point of user terminal
Title, lookup target signaling inhibits strategy in the access point name and signaling of foundation inhibit the default corresponding care of strategy.
It should be noted that the corresponding signaling of the first access point name inhibits the unit interval scheduling request threshold in strategy
Value, signaling corresponding more than the second access point name inhibit the unit interval scheduling request threshold value in strategy.Wherein, the first access
The priority of the corresponding business of point title is higher than the priority of the corresponding business of the second access point name.The high business of priority is
The task that requirement of real-time is high or significance level is high, such as the related service of bank and police service related service etc..Priority is low
Business is requirement of real-time is relatively low or significance level is relatively low business, such as radio meter register business etc..It specifically, can be in MME
The priority of the corresponding business of each access point name is stored, can each access point name pair be searched according to access point name
The priority for the business answered, the comparison for row major grade of going forward side by side.For example, the corresponding business of the first access point name notifies industry for police service
Business, the corresponding business of the second access point name be radio meter register business, due to police service notice business requirement of real-time with it is important
Degree is above radio meter register business, therefore the signaling for setting corresponding first access point name of police service notice business inhibits strategy
In unit interval scheduling request threshold value, the signaling of the second access point name corresponding more than radio meter register business inhibits in strategy
Unit interval scheduling request threshold value.
The embodiment of the present invention can inhibit according to the height of the priority of the corresponding business of access point name to set signaling
Unit interval scheduling request threshold value in strategy.The corresponding signaling of access point name of the high business of priority inhibits in strategy
Unit interval scheduling request threshold value, the corresponding signaling of access point name of the business low more than priority inhibit the unit in strategy
Time scheduling request threshold value.So that in network busy state, the related signaling request for the business for inhibiting priority low makes excellent
The Internet resources that the high business of first grade can occupy are more sufficient, and the preferential business for ensureing that requirement of real-time is high or significance level is high exists
Normal use in network inhibits the business that requirement of real-time is relatively low or significance level is relatively low, effectively alleviates network congestion.
In an example of the embodiment of the present invention, attach request, public data network connection request in scheduling request and
Service request, for whether needing the judgement inhibited to the scheduling request that user terminal is sent that can be independent.For example,
If in attach request, public data network connection request and service request, the attach request that only user terminal is sent is in unit
Quantity in time is more than the unit interval attach request threshold value during target signaling inhibits tactful, then it is corresponding to perform attach request
Scheduling request braking measure.If the attach request in scheduling request, public data network connection request and industry is explained below
Business is asked, unit interval attach request threshold value, position time during the quantity within the unit interval is tactful more than the inhibition of target signaling
Public data network connection request threshold value and unit interval service request threshold value, the required scheduling request braking measure taken.
In an example of the embodiment of the present invention, scheduling request includes attach request, unit interval scheduling request threshold value
Including unit interval attach request threshold value, then the step of scheduling request sent to user terminal inhibits, can be embodied
For：If quantity of the attach request that user terminal is sent within the unit interval is more than the unit interval in target signaling inhibition strategy
Attach request threshold value, the then attach request sent user terminal abandon.If it is embodied as the attachment that user terminal is sent and asks
It is more than the unit interval attach request threshold value during target signaling inhibits tactful to seek the quantity within the unit interval, then to user terminal
Send the refuse information for carrying specific reasons value.It should be noted that the specific reasons value carried in refuse information is used to indicate
The particular content that the request of user terminal limitation signaling is sent, such as 1 scheduling request can only be at most sent within the unit interval.
In another example of the embodiment of the present invention, scheduling request includes public data network connection request, unit interval
Scheduling request threshold value includes unit interval public data network connection request threshold value, then the scheduling request that user terminal is sent is carried out
The step of inhibition, can be specifically embodied as：If quantity of the public data network connection request that user terminal is sent within the unit interval
Inhibit the unit interval public data network connection request threshold value in strategy more than target signaling, then sent to user terminal and carry spy
Determine the refuse information of cause value；If alternatively, quantity of the public data network connection request of user terminal transmission within the unit interval
Inhibit the unit interval public data network connection request threshold value in strategy more than target signaling, then send attachment removal to user terminal
Request.It should be noted that the attachment removal type of attachment removal request is without adhering to again.
In another example of the embodiment of the present invention, scheduling request includes service request, unit interval scheduling request threshold
It is worth and includes unit interval service request threshold value, the step that the scheduling request sent to user terminal in above-described embodiment is inhibited
Suddenly it can be specifically embodied as：If quantity of the service request that user terminal is sent within the unit interval, which is more than target signaling, inhibits plan
Unit interval service request threshold value in slightly then sends the refuse information for carrying specific reasons value to user terminal；If alternatively, with
Quantity of the service request that family terminal is sent within the unit interval is more than that target signaling inhibits the unit interval business in strategy please
Threshold value is sought, then sends attachment removal request to user terminal.
For example, certain corresponding Access Point Name of radio meter register class business is known as wxcb, due to the clothes of the radio meter register class business
Device of being engaged in breaks down, and all user terminals that Access Point Name is known as the access point of wxcb is caused to go offline and the Connection Service that makes repeated attempts
Device generates a large amount of service request and public data network connection request, when a large amount of scheduling requests that happen suddenly have been more than preset unit
Between scheduling request threshold value, cause resources of core network insufficient.Core net is known as the corresponding user terminals of wxcb for Access Point Name and sends out
The scheduling request sent is limited, and is formulated public data network connection request per minute and is at most sent 1 time, service request per minute is most
It is multiple to send 1 time, it can specifically be sent by being known as the corresponding user terminals of wxcb to Access Point Name and carry the refusal of specific reasons value
Message limits the user terminal number per minute for sending public data network connection request and service request by Reason For Denial value.
The user terminal that quantity of other scheduling requests within the unit interval is not above unit interval scheduling request threshold value is unaffected,
It continues to normally send scheduling request.
In embodiments of the present invention, quantity of different types of scheduling request within the unit interval is more than that target inhibits strategy
In unit interval scheduling request threshold value, corresponding scheduling request braking measure is also different, increase scheduling request inhibition arrange
The selection space applied so that the suppressing method of signaling storm is more flexible.
Fig. 3 is the flow chart of the suppressing method of the signaling storm in further embodiment of this invention, the step 101- steps in Fig. 3
Rapid 104 is essentially identical with the step 101- steps 104 in Fig. 1.The difference lies in the inhibition sides of signaling storm shown in Fig. 3
Method further includes step 108- steps 109.
In step 108, while inhibiting to the scheduling request that user terminal is sent, start timer.
