Description
Technical field
The embodiment of the invention relates to wireless communication field, and more specifically, relates to and repeat to access device, the method and system that detects and limit.
Background technology
Based on H2H (Human to Human, the people is to the people) mobile communications network in, the terminal equipment that network is managed (as: UE (User Equipment, subscriber equipment), MS (Mobile Station, mobile radio station)) all be user oriented (namely, the user who uses these UE/MS is the people), and based on M2M (Machine to Machine, machine to machine) in the mobile communications network, the terminal equipment that network is managed may be various machinery equipments, be called MTC equipment (Machine Type Communications Device, machine type communication equipment), such as automatic vending machine, water/ammeter (being used for remote meter reading or warning etc.), household appliances etc.With respect to the UE/MS in traditional mobile communications network, these Machine Type equipment are very different, such as: for automatic vending machine, the situation that a large amount of continuous speech data usually can not occur, perhaps only allow initiatively to send data (Mobile Originated Only: only mobile originating) to network, and do not have MT (Mobile Terminated: mobile terminating) process; For water/ammeter, may only just can send data in particular moment or when response to network is inquired about; For household appliances, usually can not occur to move on a large scale.Because these machinery equipments have such Some features, may cause that network is at managerial greatest differences.Be that network can manage according to the feature (nonrandom) of MTC equipment, realize the optimization of Internet resources.
Because the quantity of following MTC equipment may be very huge, even be several times as much as the current mankind user, and the communication major part of MTC equipment has identical rule, such as the timed sending data, will occur a large amount of MTC equipment simultaneously access networks cause the situation of network congestion to occur.Standard has proposed a lot of solutions to network congestion/overload control at present.As working as MME (Mobility Management Entity, Mobility Management Entity)/SGSN (Servicing GPRS Support Node, the service GPRS support node) generation is congested, Congestion Level SPCC according to MME/SGSN, MME/SGSN can notify eNB/RNC (Radio Network Controller, radio network controller) different action, as forbid the equipment access of " time tolerant (time tolerance) ", perhaps forbid MO (Mobile Originated: the caller) equipment access of data, perhaps forbid all service accesses except urgency traffic etc., wherein MME is SAE (System Architecture Evolution, System Architecture Evolution)/LTE (Long Term Evalution, Long Term Evolution) server net equipment, SGSN is 2G/3G server net equipment, eNB is the radio reception device of SAE/LTE network, and RNC is the radio reception device of 2G/3G network.ENB/RNC will forbid corresponding equipment access like this, avoids causing MME/SGSN further to transship.Be linked in addition UE or the MTC equipment of MME/SGSN, MME/SGSN also can be according to other node congestion situations such as its Congestion Level SPCC or HSS (Home Subscriber Server, home subscriber server), thus the access of refusal UE or MTC equipment.
But, some UE, especially MTC equipment are because hardware and software failure or other reasons, can cause its continuous access network, for example, the automatic vending chance regularly or Event triggered ground connection server report its condition of sales or description of the goods, vending machine is in the time will sending these data, start communication module, communication module initiates to adhere to request to network, and network is that communication module is set up IP and carrying, and then communication module sends data to corresponding MTC application server in carrying.If breaking down, the MTC application server cause the data transmission unsuccessful, the application layer of vending machine may be thought communication failure, then restart communication module, again initiate to adhere to request, but the data transmission is still unsuccessful, so, vending machine is constantly restarted communication module, and the continuous attach to network of communication module, network constantly are its distributing IP and carrying, and attempt sending data, this process circulates.
At present the solution of prior art is: when a large amount of vending machines said process that all circulates, to cause APN corresponding to MTC application server (Access Point Name, Access Point Name) congested, namely this APN has set up a large amount of PDN (Packet Data Network, packet data network) connection and carrying, MME has obtained the congested information (whether reaching thresholding according to PDN connection or the corresponding carrying quantity set up) of APN, then MME can ask refusal with the adhering to of MTC equipment of all signatory these APN, and send one and keep out of the way timer (backoff timer), indication MTC equipment can not initiate to adhere within this time again.The method is after the access of a large amount of MTC equipment of MME process causes APN congested, and the MTC equipment that accesses is later carried out congestion control.
But, because certain UE or MTC equipment self breaks down or the MTC application server breaks down, cause this UE or MTC equipment constantly to initiate to adhere to request or other requests, but this APN is not congested, and network also can be accepted this request (rather than refusal), but but this UE or MTC equipment restart or again initiate identical or different requests, cause UE or MTC equipment constantly to repeat access, and network is constantly accepted again these accesses, increased network overhead, waste signaling (not having data to send, not accounting fee), also increased the battery consumption of UE or MTC equipment.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Embodiments of the invention are mainly used in the M2M field, and M2M is that machine is to the abbreviation of machine communication here.At present, M2M focuses on machine to the radio communication of machine, and from broadly, have following three kinds of modes: machine is to machine, and machine is to mobile subscriber (such as user's telemonitoring), and the mobile subscriber is to machine (such as user's Long-distance Control).
Fig. 1 is MTC (the Machine Type Communications according to the embodiment of the invention, machine type communication) schematic architectural diagram of using, along with the development of technology, later network architecture diagram may be different therewith, and embodiments of the invention do not limit this.
As shown in Figure 1, mainly comprise MTC equipment (MTC Device), MTC application server (MTC Server), network portion (comprising logic function bodies such as access network elements, core network element, HSS) in the framework that MTC uses.On the MTC application server, data or information that store M 2M equipment or faciation close, in order to MTC service or relevant information to be provided, for example, the MTC application server can be the water power table processing server of checking meter.MTC equipment is exactly so-called " machinery equipment ", such as communications facility or coal gas, the water power meter reading device etc. of automatic vending machine.Network provides the MTC application server to the communication between the MTC equipment, can be 3GPP network (such as GSM or UMTS or SAE system), also can be other non-3GPP networks (such as WiMAX etc.), and the present invention mainly describes based on the 3GPP network.
Embodiments of the invention are introduced as an example of 3GPP SAE/LTE example, it will be appreciated by those skilled in the art that it also is applicable to other networks such as 2G/3G GSM/UMTS network or the networks such as WiMAX, 3GPP2, be the differences such as nodename, principle is identical, repeats no more.Embodiments of the invention can also can be described for MTC equipment for UE, below, will carry out with UE the description of the embodiment of the invention as terminal.
Fig. 2 shows the indicative flowchart that repeats to access the method 10 that detects and limit according to the embodiment of the invention.The method 10 is mainly carried out by core net node (SAE/LTE network middle finger MME node, 2G/3G network middle finger SGSN node or MSC node are introduced as an example of the SAE/LTE network example).
As shown in Figure 2, repeating to access and detect and the method 10 of restriction comprises according to the embodiment of the invention:
101, detect the in the given time number of times of the access of above-mentioned subscriber equipment initiation according to the CAMEL-Subscription-Information of subscriber equipment or the configuration of core net node.
102, during more than or equal to predetermined threshold, carry out the action that is used for limiting above-mentioned subscriber equipment access at the number of times of above-mentioned access.
Like this, by detecting the access action of repeating that limits this UE in the situation that repeats to access of UE, can be for the repeating access and control of UE, thus conserve network resources.
Here, repeating to access and detect and the method 10 of restriction is repeating to certain subscriber equipment that access detects and during restriction according to the embodiment of the invention, 101 events that detect are UE the scheduled time (for example, continuous initiation N the T time) (or more than) inferior access, that is, whether detect access number of times that UE initiate in the given time more than or equal to a certain predetermined threshold N 101.If the access number of times, determines then that this UE has carried out repeating access more than or equal to this predetermined threshold N.Then 102, according to 101 for the definite result who repeats to access,, trigger and limit the action that this UE repeats to access during more than or equal to predetermined threshold N at the number of times of above-mentioned access.
Repeating to access and detect and the method for restriction is generally carried out by core net node (such as the MME node of SAE system or the SGSN node of 2G/3G system) according to the embodiment of the invention, here, repeating to access and detect and limitation function both can be used as the general utility functions of core net node according to the embodiment of the invention, also can be used as certain UE (or MTC equipment, as follows, repeat no more) signatory configuration, namely, repeat access detection and limitation function if disposed in the CAMEL-Subscription-Information of UE, the core net node executive basis embodiment of the invention repeats to access and detects and the method for restriction so, thereby this UE is repeated access to be detected and limits, repeat access detection and limitation function if dispose in the CAMEL-Subscription-Information of UE, core net node the repeating to access and detect and the method for restriction of the executive basis embodiment of the invention not just so, thus this UE is not repeated that access detects and restriction.In addition, core net node can determine whether according to the configuration of self that also UE is repeated access to be detected and limit.
As mentioned above, repeating to access and detect and the method for restriction further comprises according to the embodiment of the invention: determine whether that according to the CAMEL-Subscription-Information of the configuration of core net node or UE access to this UE repeats that access detects and restriction.And, determine access to UE repeat to access detect and the situation of restriction under, detect UE and whether carried out repeating access, and detecting in the situation that repeats to access of UE, the access that repeats of this UE is limited.Here, for example, core net node can obtain the CAMEL-Subscription-Information of UE from HSS.
In an embodiment of the present invention, repeating to access and detect and limitation function also can be used as the part that MTC monitors according to the embodiment of the invention, wherein repeat access as monitor event, access has occured to repeat as supervisory control action in restriction access or notice MTC server, and embodiments of the invention and being not intended to limit this.Here, this supervisory control action can comprise notifies this UE or MTC equipment to forbid within a certain period of time initiating access, also can comprise notice MTC application server, makes it understand the abnormal conditions of UE or MTC equipment, thereby overhaul, to reach the purpose of conserve network resources.
As mentioned above, by repeating to access and detect and the method for restriction is carried out regularly or carry out according to the core net node configuration or according to the signatory situation of UE and to repeat access and detect and limitation function according to the embodiment of the invention, can optionally carry out according to the concrete condition of UE and repeat access detection and limitation function, thereby conserve network resources, and improve the facility that the user uses.
In an embodiment of the present invention, the access that UE carries out is normally undertaken by transmission access message, and by sending dissimilar access message, UE can carry out dissimilar accesses.Therefore, according to the repeating to access and detect and the method for restriction both can repeat to any access that UE initiates access and detects and restriction of the embodiment of the invention, can repeat for the access of wherein one or more particular types also that access detects and restriction.For example, core net node can only detect the access of adhering to that UE carries out, and the number of times that adheres to access of initiating as UE in the given time is when meeting or exceeding predetermined threshold, and restriction UE continues to initiate to adhere to access, and does not process for the access of other type.Perhaps, core net node also can detect the access number of times of the access of certain several particular type, for example, that detects that UE initiates in the given time adheres to total access number of times that access and Packet Data Network's connection request (PDN Connectivity Request) access this access of two types, and when this total access number of times meets or exceeds predetermined threshold, the access that restriction UE continues to initiate to adhere to access and Packet Data Network's connection request.
As mentioned above, the method that detects and limit that repeats to access according to the embodiment of the invention determines that according to the CAMEL-Subscription-Information of subscriber equipment or the configuration of core net node needs repeat to access the access style that detects and limit, and repeat to access for needs and detect and the access of one or more particular types of restriction (comprises any type, as follows, repeat no more), detect the in the given time number of times of the access of described one or more particular types of described subscriber equipment initiation, and at the number of times of the access of described one or more particular types during more than or equal to predetermined threshold, carry out the action of the access of the one or more particular types that are used for limiting described subscriber equipment.Because the access that UE carries out is normally undertaken by transmission access message, according to the embodiment of the invention repeat to access detect and the method for restriction in, can determine to repeat to access by core net node configuration or user's signatory configuration and detect and the type of the access message of restriction.
For example, the specific access message that detects and limit can only be " adhering to request (Attach Request) " message, also can only be " service request (Service Request) " message, perhaps only be that type is " service request " message of MO signaling, also can be that " adhere to request+TAU/RAU and ask (TAU/RAU Request) ", (the SAE/LTE system was TAU, the 2G/3G system is RAU), perhaps " PDN connectivity request (PDN Connectivity Request)+adhere to request+TAU to ask (TAU Request) " wherein the message of every kind of particular type all corresponding to the access of particular type, for example, " adhere to request information corresponding to adhering to access; " service request " message accesses corresponding to service request, etc.
According to the embodiment of the invention repeat to access detect and the method for restriction in, core net node can dispose voluntarily or determine that according to the CAMEL-Subscription-Information of UE needs repeat to access the type of message of detection, namely, if the type of message of determining to repeat to access detection only comprises the message of certain type, then expression then triggers limit movement when the message of the type accesses continuously; And if configuration need to repeat to access the message that the type of message of detection comprises two or more types, message 1+ message 2 for example, then represent to regard the message of these two or more types as a class message, and when this class message accesses continuously, then trigger limit movement.And equipment of the core network can obtain by HSS the signatory configuration of UE.
For example, when the method that repeats to access detection and restriction that adopts according to the embodiment of the invention, when core net node repeats access detection and restriction to certain UE, the event that detects is that this UE is (or discontinuous continuously in the time at T, can insert other message namely) initiation N (or more than) when inferior certain class accesses (access message can be the access message of certain type or the access message of a plurality of types), trigger the access limitation action to this UE.And, can be so that UE must not carry out the access of the message of certain or a plurality of types in one section back off time for the action of the access limitation of this UE.
In addition, owing to repeat to access the deterioration of the network condition that causes, according to the embodiment of the invention repeat to access detect and the method for restriction except restriction has carried out repeating accessing the access of one or more particular types of detection, also can according to user's configuration or network indication, limit the access of other type or limit all types of accesses.
Like this, by the access style of determining that restriction repeats to access, repeating to access and detect and the method for restriction can repeat to access to needs and detects and the access style of restriction is configured according to the embodiment of the invention, thereby the access for one or more particular types (comprises any access, i.e. all accesses) optionally repeating access detects and limits, can conserve network resources, and improve the facility that the user uses.
According to the embodiment of the invention repeat to access detect and the method for restriction in, also can comprise simultaneously according to the configuration of core net node or the CAMEL-Subscription-Information of UE and determine whether the access of this UE is repeated access detection and restriction, and the access style of determining need to repeat to access detection, and the access that only needs is repeated to access one or more particular types of detection repeats to access and detects and the step of restriction.According to embodiments of the invention, preferably at first the CAMEL-Subscription-Information of the configuration of executive basis core net node or UE determines whether the access of this UE is repeated to access the step that detects and limit, and in the situation of determining to repeat to the access of this UE accessing detection and limiting, the access that repeats of carrying out again the access (also can dispose or the UE CAMEL-Subscription-Information according to core net node) for particular type detects and limits.
In an embodiment of the present invention, according to the repeating to access and detect and action that the performed restriction UE of method of restriction repeats to access can be various motion of the embodiment of the invention, for example, action 1: this access of refusal UE; Action 2: this access of refusal UE, and distribute UE to keep out of the way timer, so that UE must not access within this keeps out of the way time of timer indication, this comprises identical access or polytype access; Action 3: core net node notice MTC application server should the detection event, and namely access has occured to repeat UE, is processed by the MTC application server, such as the access of application layer restriction UE; Action 4: restriction is by the access of one or more types of user's configuration or network indication or the access of any type; Perhaps other actions.And these actions are configurable, that is, and and according to the repeating to access and detect and the method for restriction can select to carry out in these actions one or more as the case may be of the embodiment of the invention, with the access that repeats of restriction UE.
According to the embodiment of the invention repeat to access detect and the method for restriction in, can adopt several different methods to detect the access that repeats of UE.Fig. 3 shows the schematic diagram of method that repeats to access detection according to the embodiment of the invention.As shown in Figure 3, for any access, perhaps the access of specific certain type or certain several type (namely, according to certain particular type of as mentioned above configuration or the access information of certain several particular type, this information can be configured in the core net node or be included in the CAMEL-Subscription-Information of UE), according to the configuration of CAMEL-Subscription-Information or the core net node of subscriber equipment, when detecting UE and initiate access, core net node records Tn turn-on time of this time access.The core net node while has also been recorded front several times turn-on time such as T1, the T2 etc. of access in the certain hour, and may record access style (if signatory/configuration requirement detects/limits the access of some or a plurality of particular types but not accesses arbitrarily).Then, (Tn subtracts T to detect Tn-T, T is the scheduled time parameter that arranges in the CAMEL-Subscription-Information of core net node configuration or UE) interior access number of times of time, if the access number of times is more than or equal to N (N is the predetermined access number of times parameter that arranges in the CAMEL-Subscription-Information of core net node configuration or UE) in the Tn-T time, then satisfy testing conditions, can carry out access limitation.When carrying out access limitation, can delete simultaneously the access information of all records, for example turn-on time and access style are to discharge memory capacity.Otherwise, if the access number of times is not then carried out access limitation less than N in the Tn-T time.Always delete (namely deleting T window access information in addition) for the access information beyond the Tn-T time.
Fig. 4 is the flow chart of other method that repeats to access detection according to the embodiment of the invention.As shown in Figure 4, this repeat that access detects and method 20 in, at first 201, the configuration according to CAMEL-Subscription-Information or the core net node of subscriber equipment determines whether to repeat the access detection.If not, then 206, do not do extra process, finish other flow process.If, then 202, detecting UE initiation access (namely, the access information of certain particular type that disposes as mentioned above, this information can be configured among the UE or be kept in the CAMEL-Subscription-Information of UE) time, whether detection trigger this turn-on time of T# deducts T* turn-on time (if unwritten turn-on time, then think T*=T#) of record less than T (T is in the core net node configuration or the scheduled time parameter that arranges in the CAMEL-Subscription-Information of UE).If not, and the access times N * of record is less than predetermined threshold N (N is the predetermined access number of times parameter that arranges in the CAMEL-Subscription-Information of core net node configuration or UE), then 203, T* turn-on time of amendment record equals this turn-on time of T#, and access times N *=1 is set.If so, then 204, T* turn-on time that holds the record is constant, and will access times N * and add 1.Then 205, check whether access times N * is equal to, or greater than predetermined threshold N.If not, then 206, do not do extra process, finish other flow process.Otherwise, 207, trigger the action that restriction repeats to access: as refuse this access, and keep out of the way timer to UE, require UE within this keeps out of the way time of timer indication, to forbid initiating same type or polytype access, perhaps notify the MTC application server, or aforesaid other actions.These actions can be selected one or more simultaneously execution.
By such as Fig. 3 or the method that repeats to access detection as shown in Figure 4, if can detect in time T, UE has initiated inferior certain type access of N (or more than), triggers so certain action, avoids UE constantly to repeat to access and causes network overhead to increase and consumed the battery life of UE.And the described method that repeats to access detection can only just trigger when UE initiate certain particular type access, need only record at ordinary times time parameter, access number of times parameter and the specific access style parameter of corresponding UE, and network overhead is little.The time parameter here refer to as T1 turn-on time, the T2 of each time access in the method for Fig. 3 ..., Tn and scheduled time T, or such as the T* and scheduled time T turn-on time of this turn-on time of the T# in the method for Fig. 4, record.And access number of times parameter refers to the access number of times in the time such as the Tn-T in the method for Fig. 3, or such as the access times N * in the method for Fig. 4 and predetermined threshold N.
In addition, in repetition access detection method as shown in Figure 4, can also arrange, when the dissimilar access of UE initiation, the N* that whether resets, namely when UE interted dissimilar access, the effect that whether " repeats access " was interrupted.By the N* that optionally resets according to dissimilar accesses, can realize the meticulousr control to the various dissimilar access of UE, thereby improve repeating to access and detecting and the method for restriction functional of the embodiment of the invention.
When refusing the access of UE, can send refuse information to UE by core net node, described refuse information can be carried concrete Reason For Denial (as repeating admission reject) and be kept out of the way timer, even the access of notifying UE within this time, can not initiate which message, so that UE can not initiate the access of specified type within this time.
That is to say, according to the embodiment of the invention repeat to access detect and the method for restriction in, both can be in the access of core net node restricting user equipment when the action that the execution restriction repeats to access, also can not carry out the access of subscriber equipment in the core net node side, but by sending the refuse information that indication limits the access of this subscriber equipment to subscriber equipment, come to realize in subscriber equipment one side the restriction that repeats to access of this subscriber equipment.And, when according to the embodiment of the invention repeat to access detect and the method for restriction in when determining the access of one or more particular types of needs restriction, the information that can in refuse information, comprise the type of the specific access that needs limit, like this, subscriber equipment can be by this information in the refuse information that receives, stop to send to core net node the access message of indicated particular type, thereby do not initiate the access of the particular type corresponding with the access message of described particular type.Like this, by limiting function setting that access message sends in user equipment side, can reduce the cost of the equipment of core net node side, and improve the convenience that the user uses.
Fig. 5 shows the indicative flowchart according to the method 30 of the repetition access limitation of the embodiment of the invention.The method 30 is mainly carried out by subscriber equipment.
As shown in Figure 5, the method 30 according to the repetition access limitation of the embodiment of the invention comprises:
301, receive refuse information, described refuse information is carried particular type and the back off time of the access message of refusal.
302, in back off time, stop to initiate the access of described particular type.
As mentioned above, the function setting by will limiting access can reduce the cost of the equipment of core net node side, and improve the convenience that the user uses in user equipment side.
Fig. 6 shows the schematic block diagram that repeats to access the device that detects and limit according to the embodiment of the invention.As shown in Figure 6, repeating to access and detect and the device 400 of restriction comprises according to the embodiment of the invention:
Repeat to access detecting unit 401, be used for detecting the in the given time number of times of the access of described subscriber equipment initiation according to the CAMEL-Subscription-Information of subscriber equipment or the configuration of core net node.
Repeat access limitation unit 402, when being used for number of times in described access more than or equal to predetermined threshold, carry out the action that is used for limiting described subscriber equipment access.
