Below set forth the transfer resource overload processing method that the embodiment of the present invention provides.According to the transfer resource overload processing method that the embodiment of the present invention provides, the resource load of each network element to local terminal is added up, each network element reports the transfer resource load of local terminal to the Centroid of specifying, carry out load judgement by the Centroid of specifying, Centroid notice respective network elements carries out overload process afterwards.The Centroid pointed to also can be responsible for according to the transfer resource of each reported by network elements, supervises and adjust the flow of each network element, for network capacity extension upgrading provides necessary support.The transfer resource overload processing method that the embodiment of the present invention provides, is adapted to the scene that base station control device accesses an equipment of the core network, is also adapted to the scene that base station control device accesses multiple equipment of the core network.The communication network adapted to comprises the network of 2G network, 3G network and 4G network and more senior network formats, is also applicable to Wimax flattening network.Wherein, 2G network can be GSM network, and 3G network can be UMTS network.

Fig. 2 A is transfer resource provided by the invention overload processing method embodiment one flow chart.The executive agent signaling plane controlled entity of the present embodiment is the Centroid of specifying for transfer resource load judgement, is called the signaling plane controlled entity of specifying.As shown in Figure 2 A, the present embodiment comprises:

Step 21A: the signaling plane controlled entity of specifying obtains base station control device traffic messages and gateway traffic messages; Base station control device traffic messages comprises the transmitted traffic of each user interface of base station control device and receives the information of flow; Gateway traffic messages comprises the transmitted traffic of each user interface of gateway and receives the information of flow.

User entity comprises base station control device and gateway.User interface is the interface between base station control device and gateway.In the lte networks, base station control device may correspond to module close with the function of classical base station controller in eNB, and signaling plane controlled entity can be MME, and gateway can be S-GW, and user interface is the S1-U interface between eNB and S-GW; In 3G network, base station control device can be RNC, and signaling plane controlled entity can be MGW, and gateway can be SGSN, and user interface can be the IuPS interface between RNC and SGSN; In 2G network, base station control device can be BSC, and signaling plane controlled entity can be MGW, and user interface can be the Gb Interface between BSC and SGSN.

During base station control device access signaling face controlled entity, this base station control device is claimed to belong to this signaling plane controlled entity.When base station control device belongs to the signaling plane controlled entity of specifying, this signaling plane controlled entity receives the base station flow information that this base station control device sends; When base station control device does not belong to signaling plane controlled entity, the base station control device flow information that this base station control device that the signaling plane controlled entity that this signaling plane controlled entity can receive this base station control device ownership forwards reports; When base station control device belongs to multiple signaling plane controlled entity, base station control device is to one of them signaling plane controlled entity reporting base station control appliance flow information of ownership.In like manner, when gateway belongs to the signaling plane controlled entity of specifying, the signaling plane controlled entity of specifying receives the gateway traffic messages that gateway sends; When gateway does not belong to the signaling plane controlled entity of specifying, the gateway traffic messages that this gateway that the signaling plane controlled entity that the signaling plane controlled entity of specifying can receive this gateway ownership forwards reports.

Step 22A: the signaling plane controlled entity of specifying is according to base station control device traffic messages and gateway traffic messages, send for adjusting customer flow indication information to base station control device or gateway, or, send the Indication message for adjusting user's access to base station control device and/or gateway.

This Indication message can be carry out for user's access the Indication message that adjusts, also can be to carry out for customer flow the indication information that adjusts.

For LTE network, after the MME specified obtains the eNB traffic messages of each eNB and the S-GW traffic messages of each S-GW.The MME specified, according to each eNB traffic messages and each S-GW traffic messages, sends for adjusting customer flow indication information to each eNB or S-GW, or, send the Indication message for adjusting user's access to eNB and/or S-GW.Wherein, eNB traffic messages comprises the transmitted traffic of each S1-U interface of eNB and receives flow; S-GW traffic messages comprises the transmitted traffic of each S1-U interface of S-GW and receives flow; ENB is the eNB of access MME; S-GW is the S-GW be connected with eNB.When eNB belongs to the MME specified, the MME specified receives the base station flow information that this eNB sends; When eNB does not belong to the MME specified, the MME specified receives this eNB flow information of the MME forwarding that this eNB belongs to.When S-GW belongs to the MME specified, the MME specified receives the S-GW traffic messages that this S-GW sends; When S-GW does not belong to the MME specified, the MME specified receives the S-GW flow information of the MME forwarding that this S-GW belongs to.

Transfer resource overload processing method provided by the invention, the flow information of each user interface of gateway side that the flow information of each user interface in base station control device side that signaling plane controlled entity reports according to base station control device and gateway report carries out load judgement, when transfer resource transships, the indication information generated according to court verdict is sent to base station control device and gateway, make base station control device and gateway according to indication information adjustment customer flow or user's access, improve the utilization ratio of transmission resources between user entity.

Fig. 2 B is transfer resource provided by the invention overload processing method embodiment two flow chart.The executive agent of the present embodiment is user entity, and user entity can be base station control device, also can be gateway.As shown in Figure 2 B, the present embodiment comprises:

Step 21B: the descending transmitted traffic of each user interface of user entity statistics local terminal and uplink receiving flow.

User interface is the interface between local terminal and another user entity, and when local terminal is base station control device, another user interface is gateway; When local terminal is gateway, another user interface described is base station control device.For LTE network, when local terminal is eNB, another user entity is S-GW, and signaling plane entity is MME; For 3G network, when local terminal is RNC, another user entity SGSN, signaling plane entity is GMSC; For 2G network, when local terminal is BSC, another side user subject is SGSN, and signaling plane entity is GMSC.

Flow measurement granularity can user entity (eNB such as, in LTE network) be unit; The business that also can carry is unit, and as measured QCI (QoSClassIndication) type of service etc., from Realization of Product complexity, a kind of preferred mode is: measure in units of user entity.

Step 22B: user entity sends to ownership signaling plane controlled entity and comprises the up transmitted traffic of each user interface of local terminal and the traffic messages of downlink reception flow.

Step 23B: the Indication message for adjusting customer flow that user entity sends according to ownership signaling plane controlled entity, the customer flow of the user interface carried in adjustment Indication message, or, according to the Indication message for adjusting user's access that ownership signaling plane controlled entity sends, adjustment user access.

After user entity comprises the up transmitted traffic of each user interface of local terminal and the traffic messages of downlink reception flow to the transmission of ownership signaling plane controlled entity, being transmitted to by ownership signaling plane controlled entity specifies signaling plane controlled entity to carry out load judgement to user entity, and court verdict is transmitted to user entity by corresponding ownership signaling plane controlled entity.

For LTE network, after the descending transmitted traffic that eNB or S-GW adds up local terminal each S1-U interface and uplink receiving flow, send to ownership MME and comprise the up transmitted traffic of each S1-U interface of local terminal and the flow information of downlink reception flow.ENB or S-GW receive by ownership MME forward from specify MME for adjust customer flow or user's access Indication message after, according to indication information adjustment customer flow or user's access.

Transfer resource overload processing method provided by the invention, user entity is monitored the flow of respective user interface respectively and is reported to signaling plane controlled entity, when signaling plane controlled entity is according to the flow information determination transfer resource overload reported, the indication information that user entity sends according to signaling plane controlled entity adjusts customer flow or user's access, improves the utilization ratio of transmission resources between user entity.

In the corresponding embodiment of Fig. 3 A and Fig. 4 A, for the S1-U interface in LTE network between eNB and S-GW, transfer resource provided by the invention overload processing method is described.

Fig. 3 A is transfer resource provided by the invention overload processing method embodiment three flow chart.Fig. 3 B is a kind of application scenarios figure provided by the invention.As shown in Figure 3 B, same eNB has accessed different S-GW:S-GWa and S-GWb of same MME.S1-U interface between eNB and S-GWa is labeled as S1-Ua interface, and the S1-U interface between eNB and S-GWb is labeled as S1-Ub interface.The present embodiment for the eNB of in Access Network, illustrate between eNB and S-GW transfer resource overload time MME to the processing method of user's access, in Access Network, the processing method of other eNB is similar.As shown in Figure 3A, the present embodiment comprises:

Step 1:eNB and each S-GW adds up the transmitted traffic of each S1-U interface of local terminal and receives flow.

ENB adds up the transmitted traffic of S1-Ua interface and receives flow, and adds up the transmitted traffic of S1-Ub interface and receive flow.In like manner, (gateway a) adds up the transmitted traffic of S1-Ua interface and reception flow to S-GWa, and adds up transmitted traffic and reception flow that S-GWb (gateway b) adds up S1-Ub interface.

Step 2:eNB and each S-GW sends S1-UfolwstatisticReport message to ownership MME.

ENB sends S1-UfolwstatisticReport message to ownership MME, and S-GWa sends S1-UfolwstatisticReport message to ownership MME.S-GWb sends S1-UfolwstatisticReport message to ownership MME.

In the S1-UfolwstatisticReport message that eNB sends, carry the transmitted traffic of each S1-U interface of local terminal and receive flow, this overload threshold value of base station can also be carried.In the S1-UfolwstatisticReport message that S-GWa sends, carry the transmitted traffic of each S1-U interface of local terminal and receive flow, S-GWa overload threshold value can also be carried.In the S1-UfolwstatisticReport message that S-GWb sends, carry the transmitted traffic of each S1-U interface of local terminal and receive flow, S-GWb overload threshold value can also be carried.

Step 3:MME adds up the delivery flow rate of all S1-U interface of eNB, and adds up the delivery flow rate of all S1-U interface of each S-GW.

MME, by the reception flow of the transmitted traffic of eNB side S1-Ua interface, eNB side S1-Ua interface, after the transmitted traffic of eNBS1-Ub interface and the reception flow of eNBS1-Ub interface gather, obtains the delivery flow rate of all S1-U interface of eNB.MME obtains all S1-U interface delivery flow rates of S-GWa after being gathered by the reception flow of the transmitted traffic of S-GWa side S1-U1a interface and S-GWa side S1-U1a interface.MME after the same method, adds up the delivery flow rate of S-GWb.

In addition, after step 1, also can add up the transmitted traffic of each S1-U interface by eNB and S-GW and receive flow, and report respectively to ownership MME.

Step 4:MME judges that whether the delivery flow rate of eNB is more than eNB overload threshold value, and judges whether the delivery flow rate of each S-GW exceedes each S-GW overload threshold value.

MME judges that whether the delivery flow rate of base station is more than eNB overload threshold value, judges that whether the delivery flow rate of S-GWa is more than S-GWa overload threshold value, judges that whether the delivery flow rate of S-GWb is more than S-GWb overload threshold value.

Step 5:MME, according to judged result, sends the Trafficadjustmentindication message of adjustment user access to eNB and each S-GW.

Step 6:eNB and each S-GW, according to the Trafficadjustmentindication message of the adjustment customer flow of MME, adjusts user's access.

When the delivery flow rate of eNB exceedes this overloaded base stations threshold value, MME determines that eNB transships; The delivery flow rate of a S-GW exceed this S-GW carry threshold value time, MME determines that this S-GW transships.

When the delivery flow rate of eNB exceedes the overload threshold value of this eNB, MME to be connected with eNB and the S-GW that delivery flow rate does not exceed self overload threshold value sends the Trafficadjustmentindication message adjusting user's access, namely MME sends to the underloading S-GW that is connected of overload eNB the Trafficadjustmentindication message adjusting user's access.In the case, after underloading S-GW receives " Trafficadjustmentindication " message of adjustment user access, triggering overload controls, and reduces and is connected with the signaling of overload eNB, reduce the access of user.

When the delivery flow rate of an all S1-U interface of S-GW is more than S-GW overload threshold value, if eNB does not exceed the overload threshold value of this eNB, MME sends " Trafficadjustmentindication " message of adjustment user access to eNB, the user of new access is overload up on the S-GW of underloading simultaneously.Such as, the delivery flow rate of all S1-U interface of S-GWa is more than S-GWa overload threshold value, eNB is not more than eNB overload threshold value, MME sends " Trafficadjustmentindication " message of adjustment user access to eNB, the user of new access is overload up on the S-GW of other underloading simultaneously.In the case, after eNB receives Trafficadjustmentindication message, triggering overload controls, and reduces and is connected with the signaling of overload S-GWa, reduce the access request of user, thus reduce the access of user.

The overload threshold value of this S-GW is exceeded at the delivery flow rate of an all S1-U interface of S-GW, and the delivery flow rate of all S1-U interface of eNB that this S-GW is connected is when exceeding the overload threshold value of this eNB, MME sends " Trafficadjustmentindication " information of adjustment user access respectively to overload eNB and this S-GW.Such as, the delivery flow rate of all S1-U interface of S-GWa is more than the overload threshold value of S-GWa, and the delivery flow rate of all S1-U interface of eNB that is connected of S-GWa is more than the overload threshold value of eNB, MME sends " Trafficadjustmentindication " information of adjustment user access respectively to overload eNB and overload S-GWa.In the case, after information that eNB receives " Trafficadjustmentindication ", initiate up-downgoing premature beats with MME, refusal user access simultaneously.After this overload S-GW receives " Trafficadjustmentindication " information, initiate premature beats, reduce and be connected with the signaling of eNB, refusal user access.

The overload threshold value of this S-GW is not exceeded at the delivery flow rate of an all S1-U interface of S-GW, and the delivery flow rate of all S1-U interface of the eNB be connected with this S-GW is not when exceeding the overload threshold value of this eNB, S-GW and eNB transfer resource is all sufficient, MME does not send " Trafficadjustmentindication " information of adjustment user access, allows new user's access.

It should be noted that, after the judgement during MME carry out step 4, the judged result of step 4 can be sent to each network element: S-GW and eNB, be adjudicated according to judged result by each network element.

In addition, the flow information reported by eNB and S-GW, MME can know that transmission link bandwidth changes the transfer resource change caused, and MME knows the delivery flow rate of each S-GW.MME is when distributing middle certain S-GW of selection of S-GWPool (S-GWPool comprises all S-GW of this MME of ownership) and serving for user, suitable S-GW can be selected to make user's access according to the delivery flow rate of S-GW and eNB, thus select there is the S-GW of enough resources (comprising transfer resource) for user's service (such as GBR traffic and Non-GBR business).Meanwhile, the flow information reported by S-GW, MME according to S-GW actual transmissions resource utilization, can arrange the maximum bandwidth of user's access, avoids the transfer resource of eNB and S-GW side to transship.

The transfer resource overload processing method that the embodiment of the present invention provides, the flow information that MME reports according to base station and S-GW, determines the load of base station and the load of S-GW, and sends the indication information of adjustment user access to base station or S-GW according to loading condition.Base station receive MME for adjust user's access indication information after, reduce according to the instruction of indication information and be connected with the signaling of S-GW, reduce the access of user or refuse new user access, thus ensureing the quality of service of accessed user, improving S1-U interface utilization ratio of transmission resources.Equally, S-GW receive MME for adjust user's access indication information after, reduce according to the instruction of indication information and be connected with the signaling of eNB, the access of reduction user.

Fig. 3 C is transfer resource provided by the invention overload processing method embodiment four flow chart.Processing method to S1-U interface flow when present embodiments providing the transfer resource overload in the user face between eNB and S-GW.The application scenarios figure of the present embodiment is see shown in Fig. 3 B.As shown in Figure 3 C, the difference of the present embodiment embodiment corresponding to Fig. 3 A is, comprises after step 2:

Step 3:MME judges whether the transmitted traffic of same S1-U interface in eNB side is greater than the reception flow in S-GW side, and judges whether same S1-U interface is less than the transmitted traffic in S-GW side at the reception flow of eNB side.

Extract same user interface at the transmitted traffic of eNB side and the reception flow in S-GW side the S1-UfolwstatisticReport message that the S1-UfolwstatisticReport message sent from eNB and S-GW send, and extract described same user interface in the reception flow of base eNB side and the transmitted traffic in S-GW side.

Step 4: according to above-mentioned judged result, MME sends the Trafficadjustmentindication message of adjustment customer flow to eNB or each S-GW.

Step 5:eNB and each S-GW, according to the Trafficadjustmentindication message of the adjustment customer flow of MME, adjusts the customer flow of corresponding S1-U interface.

Same S1-U interface is when the transmitted traffic of eNB side is greater than the reception flow in S-GW side, MME determines uplink overload, send the Trafficadjustmentindication message of adjustment customer flow to eNB, notice eNB reduces the transmitted traffic of this S1-U interface, reduces transmission rate.ENB receives Trafficadjustmentindication message, adjusts this S1-U interface transmitted traffic, reduces S1-U interface transmission rate, to reduce the Congestion Level SPCC of eNB.

Same S1-U interface is less than when the transmitted traffic of S-GW side at the reception flow of eNB side, MME determines downlink overload, send the Trafficadjustmentindication message of adjustment customer flow to S-GW, notice S-GW reduces the transmitted traffic of this S1-U interface, reduces transmission rate.After S-GW receives Trafficadjustmentindication message, adjust this S1-U interface transmitted traffic, reduce the overload degree that S1-U interface transmission rate reduces S-GW.

Processing method to user's access when present embodiments providing the transfer resource overload in the user face between eNB and S-GW.As shown in Figure 4 A, the present embodiment comprises:

Step 1: each eNB and each S-GW adds up the transmitted traffic of each S1-U interface of local terminal and receives flow.

As shown in Figure 4 A, eNB ₁measure reception flow and the transmitted traffic of each S1-U interface.ENB ₂measure reception flow and the transmitted traffic of each S1-U interface.S-GWa measures reception flow and the transmitted traffic of each S1-U interface.S-GWb measures reception flow and the transmitted traffic of each S1-U interface.S-GWc measures reception flow and the transmitted traffic of each S1-U interface.S-GWd measures reception flow and the transmitted traffic of each S1-U interface.

Table 1 is the traffic statistics table of eNB and S-GW

Step 2: each eNB and each S-GW sends S1-UfolwstatisticReport message to ownership MME.

As shown in Figure 4 A, eNB ₁s1-UfolwstatisticReport message is sent to ownership MME1.ENB ₂s1-UfolwstatisticReport message is sent to ownership MME2.S-GWa sends S1-UfolwstatisticReport message to ownership MME1.S-GWb sends S1-UfolwstatisticReport message to ownership MME1.S-GWc sends S1-UfolwstatisticReport message to ownership MME2.S-GWd sends S1-UfolwstatisticReport message to ownership MME2.

The present embodiment adds " S1-UfolwstatisticReport " message at S1-U interface.When eNB sends " S1-UfolwstatisticReport " message to ownership MME, carry wherein: the transmitted traffic of each S1-U interface in this side and reception flow (L _mn0and L _mn1), and each S1-U interface of local terminal allows the maximum transmitted resource T of distribution _{resources-eNB}with the overload threshold value T of local terminal _overload-eNB.Wherein, T _overload-eNBbe no more than T _{resources-eNB}.

When S-GW sends " S1-UfolwstatisticReport " message to ownership MME, carry wherein: the transmitted traffic of each S1-U interface of local terminal and reception flow (R _mn0and R _mn1), and each S1-U interface of local terminal allows the maximum transmitted resource T of distribution _{resources-S-GW}with local terminal overload threshold value T _{overload-S-GW}.Wherein, T _{resources-S-GW}be no more than T _{overload-S-GW}.

Step 3:MME2 forwards S1-UfolwstatisticReport message and S-GWd and eNB of S-GWc respectively to MME1 ₂s1-UfolwstatisticReport message.

Have access to one or more eNB in MME2, equally, when also having access to one or more eNB in MME1, MME1 can receive reception flow and the transmitted traffic of each S1-U interface of multiple eNB.

Step 4:MME1 adds up the delivery flow rate of all S1-U interface of each eNB, and adds up the delivery flow rate of all S1-U interface of each S-GW.

MME1 adds up eNB ₁the delivery flow rate of all S1-U interface, eNB ₂the delivery flow rate of all S1-U interface, the delivery flow rate of all S1-U interface of S-GWa, the delivery flow rate of all S1-U interface of S-GWb, the delivery flow rate of all S1-U interface of S-GWc and the delivery flow rate of all S1-U interface of S-GWd.

Likely access one or more eNB in MME2, equally, in MM1, also likely access one or more eNB.MME1 adds up reception flow and the transmitted traffic of all S1-U interface of each S-GW in the reception flow of all S1-U interface of each eNB in different MME and transmitted traffic and different MME.With eNB _kfor example, eNB _kthe delivery flow rate T of all S1-U interface _k(1≤k≤M) is as formula 1:

$\mathrm{Tk}={\mathrm{\Σ}}_{n=1}^K{\mathrm{\Σ}}_{d=0}^1\mathrm{Lm}$ (formula 1)

With S-GW _kfor example, S-GW _kthe delivery flow rate S of all S1-U interface _k(1≤k≤N) is as formula 2:

$\mathrm{Sk}={\mathrm{\Σ}}_{m=1}^K{\mathrm{\Σ}}_{d=0}^1\mathrm{Rn}$ (formula 2)

In formula 1 and formula 2, m represents that eNB numbers, and n represents that S-GW numbers, and d represents transmission direction (d=0 represents transmission, and d=1 represents reception).

Step 5:MME1 judges whether the delivery flow rate of each base station exceedes respective overload threshold value, and judges whether the delivery flow rate of each S-GW exceedes respective S-GW overload threshold value.

MME1 judges eNB ₁delivery flow rate whether more than eNB ₁overload threshold value, MME1 judges eNB ₂delivery flow rate whether more than eNB ₂overload threshold value, judge that whether the delivery flow rate of S-GWa is more than S-GWa overload threshold value, judge that whether the delivery flow rate of S-GWb is more than S-GWb overload threshold value, judge that whether the delivery flow rate of S-GWc is more than S-GWc overload threshold value, judge that whether the delivery flow rate of S-GWd is more than S-GWd overload threshold value.If there is multiple base station, MME1 judges whether the delivery flow rate of each eNB exceedes respective overload threshold value respectively.Wherein, the overload threshold value of eNB and the overload threshold value of S-GW, can obtain respectively from " S1-UfolwstatisticReport " message that eNB and S-GW reports.

Step 6: according to judged result, MME1 sends to eNB and S-GW of ownership the Trafficadjustmentindication message adjusting user's access, and sends the Trafficadjustmentindication message of the adjustment user access of eNB and S-GW of ownership MME2 to MME2.

Step 7:MME2 forwards to eNB and S-GW of ownership MME2 the Trafficadjustmentindication message adjusting user's access.

MME1 sends Trafficadjustmentindication message to the eNB of ownership and the S-GW of ownership.For eNB and S-GW of ownership MME2, Trafficadjustmentindication message is sent to MME2, is transmitted to eNB and S-GW of ownership by MME2.Such as, MME1 according to judged result, to eNB ₁, S-GWa or S-GWb send the Trafficadjustmentindication message of adjustment user access.MME1, according to judged result, sends eNB to MME2 ₂, S-GWc or S-GWd adjust the Trafficadjustmentindication message of user access.By MME2 to eNB ₂, S-GWc or S-GWd forward the Trafficadjustmentindication message of adjustment user access.

Step 8: each eNB and each S-GW, according to the Trafficadjustmentindication message of the adjustment customer flow of MME1, adjusts user's access.

When the delivery flow rate of an eNB exceedes the overload threshold value of this eNB, MME1 determines that this eNB transships; The delivery flow rate of a S-GW exceed this S-GW carry threshold value time, MME1 determines that this S-GW transships.

When the delivery flow rate of an eNB exceedes the overload threshold value of this eNB, MME1 to be connected with this eNB and the S-GW that delivery flow rate does not exceed self overload threshold value sends the Trafficadjustmentindication message adjusting user's access, namely MME1 sends to the underloading S-GW that is connected of overload eNB the Trafficadjustmentindication message adjusting user's access.Such as, eNB ₁delivery flow rate more than eNB ₁overload threshold value time, MME1 to eNB ₁the S-GW that be connected and delivery flow rate does not exceed self overload threshold value sends the Trafficadjustmentindication message adjusting user's access.In the case, after underloading S-GW receives " Trafficadjustmentindication " message of adjustment user access, triggering overload controls, and reduces and overload eNB ₁signaling connect, reduce the access of user.

When the delivery flow rate of an all S1-U interface of S-GW exceedes the overload threshold value of this S-GW, MME1 to be connected with this S-GW and the eNB that delivery flow rate does not exceed self overload threshold value sends " Trafficadjustmentindication " message adjusting user's access, namely MME1 sends to the underloading eNB be connected with overload S-GW " Trafficadjustmentindication " message adjusting user's access, the user of new access is overload up on the S-GW of underloading simultaneously.Such as, the delivery flow rate of all S1-U interface of S-GWa more than S-GWa overload threshold value, eNB ₁not more than eNB ₁overload threshold value, MME1 is to eNB ₁send " Trafficadjustmentindication " message of adjustment user access, the user of new access is overload up on the S-GW of other underloading simultaneously.In the case, eNB ₁after receiving Trafficadjustmentindication message, triggering overload controls, and reduces and is connected with the signaling of overload S-GWa, reduce the access of user.

The overload threshold value of this S-GW is exceeded at the delivery flow rate of an all S1-U interface of S-GW, and the delivery flow rate of all S1-U interface of eNB that this S-GW is connected is when exceeding the overload threshold value of this eNB, MME1 sends " Trafficadjustmentindication " information of adjustment user access respectively to this eNB and this S-GW.Such as, the delivery flow rate of all S1-U interface of S-GWa is more than S-GWa overload threshold value, and the eNB that S-GWa is connected ₁the delivery flow rate of all S1-U interface more than eNB ₁overload threshold value, MME1 is respectively to eNB ₁" Trafficadjustmentindication " information of adjustment user access is sent with S-GWa.In the case, eNB ₁after receiving " Trafficadjustmentindication " information, initiate up-downgoing premature beats with MME1 simultaneously, reduce user's access.After information that S-GWa receives " Trafficadjustmentindication ", initiate premature beats, reduce and eNB ₁signaling connect, reduce user access.

The overload threshold value of this S-GW is not exceeded at the delivery flow rate of an all S1-U interface of S-GW, and during the overload threshold value of the delivery flow rate of all S1-U interface of the eNB be connected with this S-GW not more than eNB, S-GW and eNB transfer resource is all sufficient, MME1 does not send " Trafficadjustmentindication " information of adjustment user access, allows new user's access.

It should be noted that, after the judgement during MME1 carry out step 5, the judged result of step 5 can be sent to each network element: S-GW and eNB, carry out the judgement similar with step 6 by each network element according to judged result.

Transfer resource overload processing method between eNB and the S-GW that the present embodiment provides, belong to the flow that each eNB of different MME and each S-GW monitors local terminal S1-U interface respectively, and by eNB and MME Signalling exchange, S-GW and MME Signalling exchange, flow information is converged to and specifies MME place to carry out load judgement, by MME1, the indication information of adjustment user access is notified eNB and S-GW respectively again, each eNB and S-GW carries out overload process according to specifying the indication information of MME distribution.

Step 4:MME1 judges whether the transmitted traffic of same S1-U interface in eNB side is greater than the reception flow in S-GW side, and judges whether described S1-U interface equals the transmitted traffic in S-GW side at the reception flow of eNB side.

Step 5: according to above-mentioned judged result, MME1 is respectively to eNB ₁, S-GWa or S-GWb send the Trafficadjustmentindication message of adjustment customer flow, and send to MME2 the Trafficadjustmentindication message that ownership each eNB of MME2 and/or each S-GW sends adjustment customer flow.

MME1 according to judged result, respectively to eNB ₁, S-GWa and S-GWb send adjustment customer flow Trafficadjustmentindication message.MME1, according to judged result, sends eNB to MME2 ₂, S-GWc and S-GWd adjust the Trafficadjustmentindication message of flow.

Step 6:MME2 is to eNB ₂, S-GWc and S-GWd forward adjustment flow Trafficadjustmentindication message.

Step 7: each eNB and each S-GW, according to the Trafficadjustmentindication message of the adjustment customer flow of MME1, adjusts the customer flow of corresponding S1-U interface.

The eNB of the different S-GW of multiple MME is accessed with one of them _mfor example, eNB _ms1-U _mnthe transmitted traffic of interface and S-GW _nside S1-U _mnequal and the eNB of the reception flow of interface _mside S1-U _mnthe reception flow of interface and S-GW side S1-U _mnwhen the transmitted traffic of interface is equal, namely: L _mn0=R _mn1aMP.AMp.Amp L _mn1=R _mn0, S1-U _mnthe down link of interface and up link are all normal.Now, MME1 sends to eNBm and comprises " IncreasethetrafficofS1-Usendingdirection " and S1-U _mnthe Trafficadjustmentindication message of interface number, MME1 is also to S-GW simultaneously _nthe Trafficadjustmentindication message that transmission comprises " IncreasethetrafficofS1-Usendingdirection "." IncreasethetrafficofS1-Usendingdirection " indicates eNBm and S-GW _nbe increased in S1-U respectively _mnthe transmitted traffic of interface, but transmitted traffic can not exceed the maximum stream flow allowing to send.

ENB _mthe transmitted traffic of S1-Umn interface be greater than S-GW _nthe reception flow of side S1-Umn interface, namely: Lmn0>Rmn1, MME1 determine the uplink overload of S1-Umn interface, to eNB _mtransmission comprises " ReducethetrafficofS1-Usendingdirection " and S1-U _mnthe Trafficadjustmentindication message of interface number, instruction eNB _mreduce the transmitted traffic of S1-Umn interface, reduce transmission rate.ENB _mreceive Trafficadjustmentindication message, reduce and S-GW _nthe S1-Umn interface transmitted traffic of association, reduces this S1-Umn interface transmission rate, to reduce the Congestion Level SPCC of eNBm.

ENB _mthe reception flow of S1-Umn interface be less than S-GW _nthe transmitted traffic of side S1-Umn interface, namely: Lmn1<Rmn0, MME1 determine that S1-Umn interface downlink transships, to S-GW _ntransmission comprises " ReducethetrafficofS1-Usendingdirection " and S1-U _mnthe Trafficadjustmentindication message of interface number, notice S-GW _nreduce the transmitted traffic at S1-Umn interface, reduce transmission rate.After S-GW receives Trafficadjustmentindication message, reduce and eNB _mthe S1-U interface transmitted traffic of association, reduces this S1-Umn interface transmission rate, to reduce the overload degree of S-GW.

For the adjustment of S1-U interface transmitted traffic, the flow that can be issued by the mode of up back-pressure and transport network layer adjustment wireless network layer; Also by the buffer memory of adjustment transmission, the flow sent is carried out to the transmission of flow integer adjustment transmission data.

It should be noted that, after the judgement during MME1 carry out step 4, the judged result of step 4 can be sent to each network element: S-GW and eNB, carry out decision-making by each network element according to judged result.The present embodiment MME1, to S1-U interface flow centralized monitor, assesses to each eNB to the S1-U traffic conditions of each S-GW both sides and issues corresponding adjustment respectively and order, to improve the utilization ratio of transmission resources of eNB and S-GW.
