Below by more specifically embodiment, technical solution of the present invention is made a more detailed description.

Embodiment two,

In the present embodiment, time mainly to exceed the threshold value of setting when the load percentage of mobile management network element M1 or to transship, access network elements A1 to M2M subscriber equipment and H2H subscriber equipment the access under mobile management network element M1 carry out difference control, restriction M2M subscriber equipment accesses at heavy duty mobile management network element M1, to realize controlling the load of mobile management network element M1, be specifically described.

See a kind of load control method of Fig. 3, the embodiment of the present invention two, can comprise:

301, access network elements A1 knows the load control strategy of mobile management network element M1 about M2M subscriber equipment.

Under a kind of application scenarios, mobile management network element M1 can any time after connecting with access network elements A1, send to access network elements A1 and contain its message about the load control strategy information of M2M subscriber equipment, or, mobile management network element M1 can comprise its load control strategy information about M2M subscriber equipment in the message (such as, S1 sets up and responds (S1SetupResponse) message) connected with access network elements A1; Access network elements A1 receives this and contains the message of mobile management network element M1 about the load control strategy information of M2M subscriber equipment, from this message, know the load control strategy of mobile management network element M1 about M2M subscriber equipment, and can further the mobile management network element M1 known be stored about the load control strategy information of M2M subscriber equipment.

In addition, access network elements A1 from miscellaneous equipment (such as configuration server), can certainly know the load control strategy of mobile management network element M1 about M2M subscriber equipment; Or also can configure the load control strategy of mobile management network element M1 about M2M subscriber equipment in access network elements A1, access network elements A1 directly from the configuration of this locality, can know the load control strategy of mobile management network element M1 about M2M subscriber equipment.

Wherein, above-mentioned mobile management network element M1 specifically can determine according to embody rule scene about the load control strategy of M2M subscriber equipment.For example, mobile management network element M1 can be build, for the load control strategy of the M2M subscriber equipment of different MTCFeature or GroupID under different scene based on the application characteristic of M2M subscriber equipment or group identification about the load control strategy of M2M subscriber equipment.This load control strategy specifically can comprise: MTCFeature or GroupID different according to M2M subscriber equipment, and under the different loads situation of mobile management network element M1 or under overload, restriction M2M subscriber equipment is linked into this mobile management network element M1.

302, access network elements A1 knows the load state of mobile management network element M1.

Under a kind of application scenarios, mobile management network element M1 can send to access network elements A1 the message including mobile management network element M1 current load condition information, access network elements A1 receives this message, and knows the load state of mobile management network element M1 from this message.

Under a kind of application scenarios, access network elements A1 knows that the load state of mobile management network element M1 can be such as by knowing that the load percentage of mobile management network element M1 knows the load state of mobile management network element M1, or also can be by knowing that the load state of mobile management network element M1 is known in instruction that mobile management network element M1 transships.

For example, if access network elements A1 has known the load percentage of mobile management network element M1, can by and setting threshold value compare, know the grade of load (grade of load can comprise: slight load, intermediate part load, severe load, overload etc.) of mobile management network element M1, if known the instruction that mobile management network element M1 transships, access network elements A1 directly can determine that the load state of mobile management network element M1 is for overload.

In actual applications, the load state of mobile management network element M1 can be divided into multiple grades of load such as such as slight load, intermediate part load, severe load or overload, such as load can be defined as slight load lower than 70%, load is defined as intermediate part load between 70% to 80%, load is defined as severe load between 80% to 90%, is defined as overload more than 90%.Mobile management network element M1 such as can initiatively or under the triggering of access network elements A1, send the message including mobile management network element M1 percentage load or the grade of load to access network elements A1, access network elements A1 can know the load state of mobile management network element M1 from this message.

Be understandable that, mobile management network element M1 can by increasing field or utilizing newly-increased message in existing process messages, its load state is informed to access network elements A1, simultaneously can by its load control strategy about M2M subscriber equipment notice access network elements A1.Mobile management network element M1 can pass through one or more message, and its load state is informed to access network elements A1, simultaneously can by its load control strategy about M2M subscriber equipment notice access network elements A1.

Or also can be that when overload occurs mobile management network element M1, mobile management network element M1 sends overload to access network elements A1 and starts (OverlordStart) message, and instruction mobile management network element M1 is current is in overload; After mobile management network element M1 overload terminates, mobile management network element M1 can send overload to access network elements A1 and stop (OverlordStop) message, to indicate, mobile management network element M1 is current is in non-overloaded state, access network elements A1 then accordingly, can know the load state of mobile management network element M1.Such as the load control strategy information about M2M subscriber equipment can be included in the overload initiation message of mobile management network element transmission, can should be above-described load control strategy information about the load control strategy information of M2M subscriber equipment, also can be the wireless heterogeneous networks (RRC of all M2M application of instruction refusal, RadioResourceControl) establishment of connection, or instruction only allows the M2M application of preferential warning message business and the RRC establishment of connection of urgency traffic.

If the load percentage of 303 mobile management network element M1 has exceeded the threshold value of setting or mobile management network element M1 transships, access network elements A1 is according to the load control strategy of mobile management network element M1 about M2M subscriber equipment, and restriction M2M subscriber equipment accesses at mobile management network element M1.

Under a kind of application scenarios, access network elements A1 to M2M subscriber equipment and H2H subscriber equipment the access under mobile management network element M1 carry out difference control, restriction M2M subscriber equipment accesses (namely carrying out load control to mobile management network element M1) at mobile management network element M1 and can comprise: access network elements A1, according to mobile management network element M1 load state, refuses the access of all M2M subscriber equipmenies under mobile management network element M1; Or access network elements A1, according to mobile management network element M1 load state, accepts the access of M2M subscriber equipment under mobile management network element M1 permitting in the load control strategy of mobile management network element M1 about M2M subscriber equipment to access; Or access network elements A1, according to MTCFeature or GroupID of M2M subscriber equipment and mobile management network element M1 load state, accesses at mobile management network element M1 by corresponding percentage restriction M2M subscriber equipment; Or, access network elements A1 also can according to the load state of MTCFeature or GroupID of M2M subscriber equipment and mobile management network element M1, dynamic restriction M2M subscriber equipment is at the access rate of mobile management network element M1, when the number of the M2M subscriber equipment of unit interval inherent mobile management network element M1 access has exceeded the maximum of setting, the follow-up M2M subscriber equipment access with identical MTCFeature or GroupID in the unit interval can be refused.

For example, if mobile management network element M1 about the load control strategy of M2M subscriber equipment based on the MTCFeature of M2M subscriber equipment, then the load control strategy of mobile management network element M1 can comprise: the M2M subscriber equipment for MTCFeature being TimeTolerant application, if contain mobile management network element M1 information in its RRC connection establishment request (RRCconnectionrequest) message, can according to the load state of mobile management network element M1, limit the access of the M2M subscriber equipment of this MTCFeature by setting percentage or limit the access rate of M2M subscriber equipment of this MTCFeature, if the such as slight load of mobile management network element M1, then can not perform load to control, the access of the M2M subscriber equipment of this MTCFeature of intermediate part load limit 50% or to limit its access rate be within 500 times/second, the RRC connection establishment request of the M2M subscriber equipment of severe load or overload limit this MTCFeature all, if do not comprise mobile management network element M1 information in its RRC connection establishment request message, then can according to mobile management network element pool load state, the mobile management network element of a slight or intermediate part load selected by the dynamic M2M subscriber equipment for this MTCFeature, and according to the load condition of this mobile management network element, limit the M2M subscriber equipment access of this MTCFeature by setting percentage or limit its access rate.Access network elements A1 then can carry out load control to mobile management network element M1 accordingly.

Certainly, the M2M for other type applies, and according to the feature of its application, can arrange corresponding mobile management network element load control strategy based on this MTCFeature of M2M subscriber equipment under different loads situation respectively.

Again such as, if mobile management network element M1 about the load control strategy of M2M subscriber equipment based on the GroupID of M2M subscriber equipment, the load control strategy of mobile management network element M1 can comprise: be the special M2M subscriber equipment of certain class for GroupID, if contain mobile management network element M1 information in its RRC connection establishment request message, can according to the load state of mobile management network element M1, limit the access of the M2M subscriber equipment of this GroupID by setting percentage or limit the access rate of M2M subscriber equipment of this GroupID, such as do not perform load during slight load to control, the access of the M2M subscriber equipment of this GroupID of intermediate part load limit 20% or to limit its access rate be within 1000 times/second, access or the restriction access rate of the M2M subscriber equipment of the GroupID of severe load limit 80% are within 200 times/second, the RRC connection establishment request of the M2M subscriber equipment of overload limit this GroupID all, if do not comprise mobility management network element information in RRC connection establishment request message, then can according to mobile management network element pool load state, the mobile management network element of a non-overloaded selected by the dynamic M2M subscriber equipment for this GroupID, and according to this mobile management network element load condition, limit the M2M subscriber equipment access of this GroupID by setting percentage or limit the access of its access rate.Access network elements A1 then can carry out load control to mobile management network element M1 accordingly.

Certainly, for the M2M subscriber equipment having other different GroupID, according to the feature of M2M subscriber equipment under this group, corresponding mobile management network element load control strategy based on this GroupID of M2M subscriber equipment under different loads situation can be set respectively.

Especially, from mobile management network element M1, overload initiation message scene (this overload initiation message can comprise the load control strategy of MTCFeature or GroupID based on M2M subscriber equipment of mobile management network element M1 simultaneously) is known for access network elements A1, the RRC that access network elements A1 such as can refuse to set up for all M2M subscriber equipmenies in mobile management network element M1 connects, or the M2M user equipment urgent business in mobile management network element M1 that only accepts is connected with the RRC of preferential warning message.That is, by overload initiation message, the RRC that mobile management network element M1 can indicate access network elements A1 to refuse the foundation of all M2M business connects, or only accepts urgency traffic and preferential warning message etc.

When the load performing mobile management network element controls, access network elements can know MTCFeature or the GroupID information of M2M subscriber equipment in several ways.

For example, MTCFeature or the GroupID information etc. of this M2M subscriber equipment can be comprised in the RRC connection request message that M2M subscriber equipment is initiated to access network elements A1, access network elements A1 according to MTCFeature or the GroupID information comprised in this message, can know application characteristic or the group identification of this M2M subscriber equipment.Now, access network elements A1 can according to mobile management network element M1 based on the load control law of MTCFeature or GroupID of M2M subscriber equipment, the load state of mobile management network element M1 and MTCFeature or GroupID of M2M subscriber equipment known, the access of restriction M2M subscriber equipment or access rate, and then realize controlling the load of mobile management network element M1.

Or also can be, when introducing M2M application, the access community (cell) of M2M application is planned, make M2M subscriber equipment only access access network elements by specific community (cell), and specific cell can only allow the M2M subscriber equipment of specific GroupID to access.

Concrete methods of realizing can be as follows: the cell of access M2M subscriber equipment is referred to as M2MCell, the mapping relations of M2Mcell and specific GroupID are set up in access network elements, M2Mcell can comprise GroupID corresponding to this M2Mcell in cell broadcast messages, so, M2M subscriber equipment is after receiving cell broadcast messages, if when the GroupID in discovery cell broadcast messages is identical with the GroupID of self, this community is selected to access.Access network elements can support multiple Cell, each Cell uses corresponding GroupID to distinguish different M2M subscriber equipment accesses, like this, different GroupID can be comprised in different cell broadcast messages, the M2M subscriber equipment of different GroupID can select corresponding Cell to access according to the GroupID of oneself, the cell ID of the Cell that access network elements can access according to M2M subscriber equipment and this locality configuration and the GroupID map information of M2M subscriber equipment, know the GroupID information of the M2M subscriber equipment of initiating the request of RRC connection establishment.

Especially, the map information of MTCFeature and GroupID of M2M subscriber equipment can be obtained further from configuration server at the map information of MTCFeature and GroupID of access network elements A1 this locality configuration M2M subscriber equipment or wireless access network.If the load control law of the mobile management network element M1 that access network elements A1 is known in step 301 is based on GroupID, and access network elements A1 is current, and what know is the MTCFeature information of M2M subscriber equipment, then access network elements A1 can according to this locality configuration or the map information of MTCFeature and GroupID that obtains from configuration server, know the GroupID of M2M subscriber equipment, carry out load control accordingly.Similar, if the load control law of the mobile management network element M1 that access network elements A1 is known in step 301 is based on MTCFeature, and access network elements A1 is current, and what know is the GroupID information of M2M subscriber equipment, then access network elements A1 can according to this locality configuration or the map information of MTCFeature and GroupID that obtains from configuration server, know the MTCFeature of M2M subscriber equipment, carry out load control accordingly.

Further, when not being the load control strategy based on MTCFeature or GroupID for the load control strategy about M2M subscriber equipment, such as, it is the load control strategy applied based on all M2M, the M2M application message of instruction M2M subscriber equipment can be known (such as equally by above various ways, can comprise M2M application indication information in RRC connection request message, or specific cell can only allow the scenes such as M2M subscriber equipment access).

Access network elements A1 performs mobile management network element M1 load and controls, and result can be controlled to M2M subscriber equipment transmission RRC connection acceptance (RRCConnectionAccept) message or RRC connection refusal (RRCConnectionReject) message according to load, be accepted to indicate the connection of M2M subscriber equipment or be rejected.

Be appreciated that, control to be described for the load of access network elements A1 execution mobile management network element M1 in the present embodiment, by mobile management network element M1 according to the load state of self and the load control strategy about M2M subscriber equipment, load control can certainly be carried out to self; Or also can carry out load by other third party device to mobile management network element M1 to control, its load control principle is similar, repeats no more herein.

Therefore, time in this enforcement to exceed the threshold value of setting when the load percentage of mobile management network element M1 or to transship, access network elements A1 to M2M subscriber equipment and H2H subscriber equipment the access under heavy duty mobile management network element carry out difference control, by the access of restriction M2M subscriber equipment at heavy duty mobile management network element, load control is carried out to different M2M application, can relatively avoid or reduce M2M application on the one hand to the impact of H2H application, be conducive to the normal access ensureing H2H application, be conducive to the normal access ensureing that special M2M applies on the other hand.
