Embodiment

In order to make the embodiment of the invention clearer, following elder generation is simply described the radio gradual network structure that the embodiment of the invention is suitable for, and need to prove, the embodiment of the invention is not limited to be suitable for this network architecture, also goes for other networks.As shown in Figure 1, the core net of wireless evolution network mainly comprises MME (Mobility Management Entity, mobile management network element), Serving Gateway (gateway, S-GW), PDN Gateway (grouped data network gateway, P-GW) three logic function bodies, MME wherein is a mobile management net element, is responsible for functions such as NAS (Non-Access Stratum) signaling and the encryption of NAS signaling and roaming, tracking, distributing user temporary identity sign, safety function etc.ServingGateway is responsible for the local mobility anchor point and the mobility anchor point and the Lawful Interception relevant information of 3GPP internal system; PDN Gateway then is responsible for strategy execution and charging and Lawful Interception correlation function.HSS (Home Subscriber Server, home subscriber server) is used for storing user subscription information.

Embodiment one:

The embodiment of the invention one provides a kind of load bearing management method, comprising:

First Mobility Management Entity determines that the subscriber equipment that is carrying out urgency traffic is in professional restricted mode;

It is unavailable to control described non-emergent service bearer.

Wherein, in present embodiment and the subsequent embodiment, the carrying attribute of subscriber equipment can be ARP (the Allocation and Retention Priority of carrying, distribute and maintenance priority), perhaps Cheng Zai Qos, APN (Access Point Name, APN) during perhaps PDN links.

When the embodiment of the invention is in professional restricted mode at the subscriber equipment that carries out urgency traffic, first Mobility Management Entity that UE inserted keeps non-emergent service bearer, and it is unavailable to control non-emergent service bearer, so that the subsequent user device translates is to business not during restricted mode, recovery business that can be very fast promotes user experience.

Illustrate: present embodiment and subsequent embodiment focus on the user owing to moving or access technology changes reason such as latter's subscription data change and causes the user can not insert in current location/time/access network/access technology, transfer the Mobility Management Entity whether professional restricted mode and user can change access to and do not have positive connection.For explaining conveniently, it is that example describes that the present invention has all only changed Mobility Management Entity with the user.Same, the user when professional restricted mode is converted to normal mode and user's Mobility Management Entity that whether can change access do not have positive connection yet, for explaining conveniently, it is that example describes that the present invention has only changed Mobility Management Entity with the user.

Embodiment two:

Consult Fig. 2, the embodiment of the invention two provides a kind of load bearing management method, the UE that carries out urgency traffic in this method switches to target mobility management entity from the source Mobility Management Entity, it is unavailable that network side will be controlled non-emergent service bearer, in the embodiment of the invention and subsequent embodiment three and four, target mobility management entity is also referred to as first Mobility Management Entity, and this load bearing management method specifically comprises:

B1, UE switch to target mobility management entity from the source Mobility Management Entity.

B2, UE send position updating request to target mobility management entity, and this position updating request can be route district/tracing section updating request.

After B3, target mobility management entity receive position updating request,, then obtain user's subscription data from HLR/HSS (attaching position register/home subscriber server) if do not preserve this user's contextual informations such as subscription data.

B4, target mobility management entity determine according to user contracting data whether customer service is limited, if target mobility management entity is checked that UE is current and whether carried out urgency traffic, if UE is carrying out urgency traffic, then permits user's access.If it is unavailable that the carrying that the user exists non-emergent business to be correlated with, Mobility Management Entity are provided with the non-emergent service bearer of UE.

Wherein, user contracting data can comprise in present embodiment and the subsequent embodiment: access zone/network, access technology and at least a in turn-on time that the user allows or is not allowed to, in this step target mobility management entity according to user contracting data determine customer service whether limited specifically be to judge whether customer service inserts zone/network limited or whether access technology is limited or whether turn-on time is limited.Wherein, inserting the limited UE of being meant in zone inserts and does not allow the zone inserted; Access technology is limited can be meant that UE has inserted and not to allow the access technology that inserts, and such as 2G, 3G or LTE etc., access network is limited can be meant that the user has inserted and not to allow the network that inserts, is not allowed to access CHINAUNICOM such as the user of China Mobile.

Wherein, target mobility management entity can be according to ARP (the Allocation and RetentionPriority of carrying, distribute and keep priority) whether be urgent ARP or set up in the PDN link according to the user and to have or not urgent APN (Access Point Name, APN) to judge whether the user carries out urgency traffic.

Following branch (1), (2), (3) or (4) big section are described the handling process of network side, and wherein, network side can have the processing mode of the non-emergent service bearer of UE: (1), (2), (1)+(3), (2)+(3) or (4) these several implementations.

(1), the carrying relevant to non-emergent business, target mobility management entity can loaded state be set to unavailablely, be about to loaded state and be set to invalid or hang up, simultaneously:

Target mobility management entity sends more new bearer request to gateway, more carry the limited indication information of customer service in the new bearer request, the limited indication information of this customer service can be a limited-service indication information element (Service Restriction Indication), indicating service gateway UE is inserting the zone, access technology or turn-on time business limited, the notification service gateway will carry hang-up, after gateway is received the limited-service indication information element, whether can be the relevant carrying of urgency traffic according to judgements such as the Qos carrying of ARP in the user's context that prestores or carrying, the state of the carrying that non-emergent business is relevant be set to invalid or suspended state; Perhaps, the limited indication information of this customer service can be a beared information, and such as the status list of carrying, wherein, the state of non-emergent service bearer is set to hang up/invalid, the state of the non-emergent service bearer of gateway is set to hang up/and invalid.Perhaps, target mobility management entity all sends bearer update message at every non-emergent service bearer, the entrained limited indication information of customer service can be the state (promptly hanging up/invalid) of this carrying in the bearer update message at this moment, this moment, gateway was received after the bearer update request that should carry, know that according to the state of this carrying this carrying is unavailable, the state that gateway should carry is set to hang up/and invalid.The limited indication information of customer service in present embodiment and the subsequent embodiment also can comprise above-mentioned three kinds of forms, does not influence realization of the present invention.Follow-up when receiving the relevant packet of non-emergent service bearer, the direct packet discard of gateway does not send downlink data notification downlink data notification message to target mobility management entity.

Perhaps:

Target mobility management entity sends to gateway and hangs up Suspend message, can carry the limited indication information of customer service in the message, the limited indication information of this customer service can be to need the carrying ID that hangs up to tabulate or professional limited indication information element or both combinations, limited with the indicating service gateway customer service, non-emergent professional relevant bearer need be hung up.

Wherein, the limited indication information of customer service can be beared information or professional limited indication information element; The state of non-emergent service bearer is unavailable in the described beared information.The state that carries in the embodiment of the invention and the subsequent embodiment is unavailablely to be: the state of carrying be invalid/hang up.Related network elements (gateway and grouped data network gateway) receives the data of relevant bearer, and directly packet discard is perhaps preserved still past other network elements transmissions of packet or notified other network elements that downlink data packet is arranged.That is: gateway can not send downlink data notification message (DownLink Data Notification) notice to Mobility Management Entity downlink data.Grouped data network gateway can not send packet to gateway.

Wherein, do not need the carrying ID that hangs up to tabulate if do not carry in the suspend message, whether gateway is the relevant carrying of urgency traffic according to judgements such as the Qos carrying of ARP in the user's context that prestores or carrying, the state of the carrying that non-emergent business is relevant is set to invalid or suspended state, but deleting bearing not.Follow-up when receiving the relevant packet of non-emergent service bearer, the direct packet discard of gateway does not send downlink data notification downlink datanotification message to target mobility management entity.

(2), the carrying that non-emergent business is correlated with, MME can utilize existing bearer update message (Update Bearer Request) or other can the limited message of notification service gateway customer service, it is limited to carry the limited indication information indicating service gateway of customer service user region business in the message, the business that can only carry out specific (special) requirements such as urgency traffic;

After gateway is received the limited indication information of customer service, send bearer update message or the limited message of other notice packet data network gateway customer services to grouped data network gateway, carry the limited indication information of customer service in the message, this information indication grouped data network gateway user region business is limited, the business that can only carry out specific (special) requirements such as urgency traffic.

Need the carrying ID that hangs up to tabulate if carry in the limited indication information of customer service, then grouped data network gateway does not need to judge that those carryings are relevant with urgency traffic, otherwise, grouped data network gateway needs oneself to judge which carrying is relevant with urgency traffic, can whether be urgent ARP according to the APR of carrying, whether the APN that carrying is relevant is urgent APN, perhaps the carrying ID that sends by gateway judges which is carried as non-emergent service bearer, which is carried as the urgency traffic carrying, to non-emergent service bearer, packet data network network gateway (PDN GW) can have following two kinds of processing modes:

1, the recording user business is limited, and the state of non-emergent professional relevant bearer is set to unavailable or hang-up, and is follow-up when receiving the packet that these carryings are correlated with, and to the gateway transmission, directly bag do not abandoned.

If 2 have disposed static PCC rule, the packet data network network gateway is closed the door of non-emergent business data flow, if perhaps adopt the processing mode of (1)+(3), then can only close the door of the non-emergent business data flow of non-GBR.

If disposed dynamic PCC rule, (Police and Charging Rule Function PCRF) sends session modification message to the packet data network network gateway with the charging rule functions point to strategy.Carry professional limited indication (Service Restriction Indication) message in the message, this user of indication PCRF can only carry out particular services such as urgent call inserting zone, access technology, turn-on time or services of roaming restriction.A perhaps nearer step, can also carry indication information in the message, indication which data streaming service data flow of PCRF (SDF Service Data Flow) is the relevant data flow of urgency traffic, which is not the relevant data flow of urgency traffic.

After PCRF receives professional limited indication, close the door (gate) of non-emergent service related data stream, can also formulate new PCC rule, and send the session modification response message, carry the new PCC rule of having revised the door state in the message to grouped data network gateway.

Further, PCRF is all right: and the notice Application Function (Application Function, AF), customer service is limited, and AF no longer initiates the relevant business of non-emergent business; Perhaps, the relevant business of non-emergent business that PCRF initiates AF, refusal is handled.PCRF can also be notified to AF with the reason (customer service is limited) of refusal, so that AF no longer initiates the relevant business of non-positive business.

After grouped data network gateway was received the session modification response message, the door state of non-emergent service related data stream was set to close, and promptly closes the door of these data flow, and sends response message to gateway.Gateway sends response message to mobile management network element again.

(3), GBR (Guarantee Bit Rate the guarantee bit rate) carrying relevant to non-emergent business, target mobility management entity can loaded state be set to invalid or hangs up.Specifically can adopt following both modes:

1, the GBR carrying that target mobility management entity deletion user's non-emergent business is relevant, target mobility management entity sends deleting bearing request Delete Bearer Request message to gateway, after gateway is received the deleting bearing request, delete the relevant GBR carrying of non-emergent business, and send deleting bearing request Delete Bearer Request message to grouped data network gateway, the notice packet data network gateway is deleted the relevant GBR carrying of non-emergent business, and grouped data network gateway is deleted the relevant GBR carrying of non-emergent business and returned response message to gateway.

2, target mobility management entity is revised the relevant GBR of the non-emergent business of user (Guarantee BitRate guarantees bit rate) carrying, and the GBR and/or the MBR (Maximum Bit Rate, Maximum Bit Rate) of the GBR carrying that non-emergent business is relevant reduce to 0.Target mobility management entity sends bearer update request (Update Bearer Request) message to gateway, and the GBR and/or the MBR of the GBR carrying that indicating service gateway is relevant with non-emergent business reduce to 0.After gateway is received the bearer update request, the GBR and/or the MBR of the GBR carrying that non-emergent business is relevant are set to 0, and send more new bearer request (Update Bearer Request) message to grouped data network gateway, grouped data network gateway is revised the relevant carrying of non-emergent business, the GBR and/or the MBR of the GBR carrying that non-emergent business is relevant reduce to 0, and return response message to gateway.

Should (3) can combine the processing that realizes non-emergent service bearer with (1) or (2), now illustrate 2 in (3) how with (1) in conjunction with the processing that realizes non-emergent service bearer: target mobility management entity is revised the relevant GBR of the non-emergent business of user and is carried, the GBR and/or the MBR of the GBR carrying that non-emergent business is relevant reduce to 0, send more new bearer request to gateway, more carry the limited indication information of customer service in the new bearer request and indicate the GBR bearing parameter to be set to 0 information; After gateway was received the bearer update request, the GBR and/or the MBR of the GBR carrying that non-emergent business is relevant were set to 0, and according to the limited indication information of customer service, the state that the carrying of non-emergent business is set is hang-up or invalid.Gateway also sends more new bearer request (Update BearerRequest) message to grouped data network gateway, grouped data network gateway is revised the relevant carrying of non-emergent business, the GBR and/or the MBR of the GBR carrying that non-emergent business is relevant reduce to 0, and return response message to gateway.

(4), no matter be also right and wrong GBR carrying of GBR carrying, as long as and urgency traffic is irrelevant, target mobility management entity is used for the limited message of notification service gateway customer service to gateway transmission bearer update message or other, such as Service Restriction Notification, carry the limited indication information of customer service in the message, the indicating service gateway customer service is limited, can only carry out particular services such as urgency traffic.

Gateway is used for the limited message of notice packet data network gateway customer service to grouped data network gateway transmission bearer update request or other after receiving message, such as Service RestrictionNotification, carry the limited indication information of customer service in the message, indication grouped data network gateway customer service is limited, can only carry out particular services such as urgency traffic.

If disposed static PCC rule, grouped data network gateway GBR and/or MBR are set to 0, and the door of non-emergent business data flow is closed.After if GBR and/or MBR reduce to 0, the carrying that needs to be correlated with merges the more new technological process that can also initiate to carry.Perhaps grouped data network gateway is initiated the deleting load-bearing flow process with the relevant GBR deleting load-bearing of non-emergent business, flow process comprises: PDN GW notice S-GW deletes the relevant GBR carrying of non-emergent business, and S-GW notice Mobility Management Entity is deleted the relevant GBR carrying of non-emergent business.

If disposed dynamic PCC rule, grouped data network gateway sends session updates message to PCRF, carry customer service limited (Service Restriction Indication) indication information element in the message, indication PCRF user insert zone, access technology and/or turn-on time business limited, can only carry out particular services such as urgency traffic.

After PCRF knows that customer service is limited, at the relevant data flow of non-emergent business, if be the GBR data flow of non-emergent business, can GBR and/or MBR be set to 0 (not necessarily), set up new PCC rule, perhaps delete the GBR data flow of non-emergent business, and notice PDN GW deletes non-emergent professional GBR data flow.Grouped data network gateway is initiated the deleting load-bearing flow process with the relevant GBR deleting load-bearing of non-emergent business then, flow process comprises: PDN GW notice S-GW deletes the relevant GBR carrying of non-emergent business, and S-GW notice Mobility Management Entity is deleted the relevant GBR carrying of non-emergent business.PCRF also can close by the data flow door that non-GBR carries or all non-emergent business are correlated with that non-emergent business is relevant, send the session updates response message to grouped data network gateway, carry new PCC Rule Information in the message, wherein, the data flow door state that the non-emergent business of indication is relevant in the new PCC rule is for closing, perhaps, the GBR and/or the MBR of the GBR of non-emergent business carrying are set to 0, and the door state of the non-GBR data carried by data stream of non-emergent business is for closing.

After receiving message, grouped data network gateway according to new PCC rule with the door status modifier of non-emergent business data flow for the state of closing (closed) or non-emergent service bearer be set to hang up/invalid.Perhaps, if in the PCC rule GBR of the GBR of non-emergent business carrying and/or MBR be set to 0 and the door state of the non-GBR data carried by data stream of non-emergent business for closing, then the GBR and/or the MBR of the GBR of non-emergent business carrying are set to 0, and the door of the non-GBR data carried by data stream of non-emergent business is closed, and grouped data network gateway may be initiated the bearer update flow process according to new PCC rule.If the GBR and/or the MBR of the GBR of the non-emergent business of grouped data network gateway carrying are set to 0, the GBR bearing parameter that then needs to send the non-emergent business of indication to service is set to 0 information, the GBR and/or the MBR of the GBR carrying of the non-emergent business of gateway are set to 0, and the GBR bearing parameter that sends the non-emergent business of indication to target mobility management entity is set to 0 information; The GBR and/or the MBR value of the GBR carrying of the described non-emergent business of described target mobility management entity are set to 0, target mobility management entity also can send to UE indicates the GBR bearing parameter of non-emergent business to be set to 0 information, and the GBR and/or the MBR value of the GBR carrying of the non-emergent business of UE are set to 0

B5, target mobility management entity discharge the relevant bearing resource of the non-emergent business of Access Network.

Wherein, target mobility management entity (first Mobility Management Entity) need send a notification message to access network element (this access network element is called first access network element), this notification message is used to notify this access network element deletion user's switching restriction, perhaps, the notice access network element is revised user's switching restriction, to guarantee when the user has urgency traffic, not inserted the restriction of zone, access technology and/or turn-on time, then access network element deletion user's switching restriction, perhaps, keep the roaming restriction, will insert regional, access technology and/or turn-on time limit deleting.

B6, target mobility management entity send the position renewal to UE and accept message, can be that route district/tracking area is accepted message, carry the limited indication information of customer service in the message, the indication customer service is limited, and can only carry out particular service such as urgency traffic or carry needs to hang up/invalid carrying tabulation or both combinations.

After UE is notified, can distinguish urgent or non-emergent business according to carrying APN or ARP etc., invalid/hang-up that the state of non-emergent service bearer is set to, also can be set to invalid/suspended state according to the relevant carrying of accepting in the message of the non-emergent business of carrying tabulation, and non-emergent business is not initiated in control, promptly except that urgency traffic, the user wouldn't ask Internet resources or send upstream data.

B7, after urgency traffic is finished, according to user contracting data, if judge that to obtain under the UE present case business not limited, if access network element has been deleted and has been switched restriction in B5, then target mobility management entity sends initial context to access network element and sets up request message, again add the switching restriction with request, access network element adds and switches restriction, and sets up response message to target mobility management entity transmission initial context; If access network element has been deleted the partial content that switches restriction in B5, then second mobile management network element sends user's context to access network element and revises request, revise the switching restriction with request, the access zone, access technology and/or restriction turn-on time that are about to delete among the B5 are added to again and are switched in the restriction, access network element is revised and is switched restriction, and to target mobility management entity transmission user's context modification response, wherein, initial context is set up request/user's context and is revised the switching limit request that request is the recovery user.

If it is still limited that judgement obtains customer service, then initiate separation process to UE, separates UE is with all carryings of deletion UE.

The embodiment of the invention one is after the UE that carries out urgency traffic switches to target mobility management entity from the source Mobility Management Entity, after under the limited situation of customer service, keep non-emergent service bearer, and it is unavailable to control non-emergent service bearer, guarantees under the limited situation of customer service, UE can not be except that urgency traffic other business, avoid operator's unnecessary loss, and, so that the subsequent user business is when no longer limited, the quick-recovery business promotes user experience soon.

Embodiment three:

Consult Fig. 3, the embodiment of the invention three provides a kind of load bearing management method, the UE that carries out urgency traffic in this method switches to target mobility management entity from the source Mobility Management Entity, and network side will be controlled non-emergent service bearer deletion, and this method specifically comprises:

C1, UE switch to target mobility management entity from the source Mobility Management Entity.

C2, UE send position updating request to target mobility management entity, and this position updating request can be route district/tracing section updating request.

If it is invalid that the C3 target mobility management entity is not preserved the user context information of user's contextual information or preservation, target mobility management entity sends position updating request to HLR/HSS (attaching position register/home subscriber server).HLR/HSS sends the position to target mobility management entity and upgrades affirmation, and user contracting data is carried in upgrading and confirming in the position.

Target mobility management entity is according to user contracting data, determine whether customer service is limited, target mobility management entity sends route district/tracking area to UE and accepts message, if customer service is limited, can carry the Cause cause value in the message, cause value indication customer service is limited, can only carry out particular services such as urgency traffic, and perhaps route district/tracking area is accepted to carry in the message needs to hang up/invalid carrying tabulation or both combinations.After UE is notified, distinguish urgent or non-emergent business according to carrying APN or ARP etc., the carrying that non-emergent business is relevant is set to suspended state; Perhaps in the carrying tabulation that preserve this locality the state of indicated carrying be set to hang up/invalid, UE wouldn't ask Internet resources or transmission upstream data except that urgency traffic.

C4, target mobility management entity are initiated load bearing deactivation/deletion flow process, the carrying that deletion user's non-emergent business is relevant after transmission route district/tracking area is accepted message.

Wherein, target mobility management entity (first Mobility Management Entity) need send a notification message to access network element (this access network element is first access network element), this notification message is used to notify access network element deletion user's switching restriction, perhaps, the notice access network element is revised user's switching restriction, to guarantee when the user has urgency traffic, not inserted the restriction of zone, access technology and/or turn-on time, then access network element deletion user's switching restriction, perhaps, keep the roaming restriction, will insert regional, access technology and/or turn-on time limit deleting.

C5, after urgency traffic is finished, according to user contracting data, if judge that to obtain under the UE present case business not limited, if access network element has been deleted and has been switched restriction in C4, then target mobility management entity sends initial context to access network element and sets up request message, again add the switching restriction with request, access network element adds and switches restriction, and sets up response message to target mobility management entity transmission initial context; If access network element has been deleted the partial content that switches restriction in C4, then second mobile management network element sends user's context to access network element and revises request, revise the switching restriction with request, such as: insert zone, access technology and/or restriction turn-on time and add to again in the switching restriction, access network element is revised and is switched restriction, and sends user's context modification response to target mobility management entity.

If judge that to obtain under present case customer service still limited, determine that promptly UE can not insert, then initiate the separate users flow process, deletion user all carrying and separate users.

Present embodiment three is after UE switches, if the customer service of UE is limited, the non-emergent professional relevant bearer of deletion user when target mobility management entity allows the user to insert, the urgency traffic that so promptly guarantees the user can carry out, can guarantee other business that the user can not be except that urgency traffic again, avoid operator's unnecessary loss.Further, after urgency traffic is finished, add or revise the switching restriction of the user in the access network element, can guarantee the user under the situation that does not have urgency traffic to carry out, can only do and switch the switching that restriction allows.

Embodiment four:

Consult Fig. 4, the embodiment of the invention four provides a kind of load bearing management method, the UE that is used for carrying out urgency traffic moves to the 3GPP network from non-3GPP network, wherein, when UE moves to the 3GPP network from non-3GPP network, can directly in 3GPP, register, data flow is switched to the 3GPP network, be referred to as non-optimized switchover.Perhaps, UE is linked into the 3GPP network again after the success, and data flow is switched to the 3GPP network by non-3GPP network pre-registration in the 3GPP network, is referred to as to optimize and switches.The mode that present embodiment does not limit the UE switching is to optimize or non-optimized switchover.This method specifically comprises:

D1, UE initiate to adhere to request to target mobility management entity.

UE can directly send to target mobility management entity and adhere to request in this step, also can send to target mobility management entity by non-3GPP network and adhere to request.

D2, target mobility management entity send location update message to HLR/HSS.

D3, HSS/HLR send the position to target mobility management entity and upgrade acknowledge message, carry user's subscription data in the message.

D4, target mobility management entity are according to user contracting data, determine whether customer service is limited, if customer service limited (be the user can not current region/access technology/turn-on time/carry out business in the roaming restriction), target mobility management entity judges according to the user contracting data that HSS/HLR sends whether the user exists urgency traffic, such as the APN that whether has urgency traffic etc.Need to prove: judge customer service whether limited with judge whether the user exists urgency traffic not have sequencing.

Target mobility management entity determines that customer service is limited, and the user is when having urgency traffic, sends to gateway and sets up the default bearer request message, carries the limited indication information of customer service in the message, and the indicating service gateway customer service is limited.

D5, gateway receive after default bearer sets up request message, send to grouped data network gateway and set up the default bearer request message, carry the limited indication information of customer service in the message, and indication grouped data network gateway customer service is limited.After grouped data network gateway is received message, according to the limited indication information of business, know that active user's business is limited, at the relevant data flow of non-emergent business, grouped data network gateway can not initiated dedicated bearing and be set up flow process and set up these dedicated bearings.Grouped data network gateway can also be closed the door of non-emergent service related data stream in the default bearer or also can be initiated the bearing modification flow process, the Business Stream that non-emergent business is relevant deletion from carrying.

D6, grouped data network gateway also can with PCRF alternately to PCRF initiation session renewal/modification message, carry the limited indication information of customer service in the message, the limited indication information of this customer service can be professional limited indication (Service Restriction Indicator) cell, and indication PCRF customer service is limited.PCRF receives after the message limited according to customer service, it is unavailable to control non-emergent service related data stream, can formulate new PCC rule, wherein, controlling non-emergent service related data stream unavailable can be that the door of the non-emergent service related data stream of user is closed, and perhaps deletes these data flow.

PCRF sends session updates/modification response message to grouped data network gateway, can comprise new PCC rule in the message, can close (closed/close) by the data flow door that non-emergent business is relevant in the new PCC rule, perhaps that non-emergent business is relevant data flow deletion, perhaps only delete the relevant GBR data flow of non-emergent business, after grouped data network gateway is received message, the data flow door that non-emergent business is relevant is closed, perhaps initiate the bearing modification flow process the relevant GBR data flow of non-emergent business is deleted or only deleted to the non-emergent service related data stream of user, do not initiate dedicated bearing and set up the request flow process.

Further, PCRF can also carry professional limited (ServiceRestriction Indicator) indication information in reporting events, and AF knows that customer service is limited after receiving message, no longer initiates non-emergent business to UE.AF sends acknowledge message or new application/service message to PCRF.

Perhaps, when PCRF receives the non-emergent service request of AF initiation, refuse this non-emergent service request.

This step is an optional step.

D7, grouped data network gateway send to gateway and set up the default bearer response message.

D8, gateway send to target mobility management entity and set up the default bearer response message.

D9, target mobility management entity send to adhere to the user accepts message.Carry the limited indication information of customer service in the message, limited with the notice customer service, after UE receives message, know that business is limited, can not initiate the bearing resource request/modification of non-emergent business, can not initiate non-emergent professional PDN linking request yet.The non-emergent business datum stream mode in UE this locality is set to hang up/and unavailable.

Can be that target mobility management entity directly sends to adhere to UE and accepts message in this step, also can be will adhere to by non-3GPP network to accept message and send to UE, do not influence realization of the present invention.

UE is when non-3GPP network moves to the 3GPP network in the embodiment of the invention four, if the customer service of UE is limited, grouped data network gateway is not initiated the flow process of setting up of non-emergent service bearer, with other business of guaranteeing that UE can not be except that urgency traffic, avoid operator's unnecessary loss.

Consult Fig. 5, after the following user's of being presented in non-emergent carrying was suspended, under abnormal conditions, the user asked the processing of recovering bearing, and to guarantee that UE when customer service is limited, except that urgency traffic, can not carry out non-emergent business, the possible scene of generation is as follows:

1. after user's urgency traffic was finished, perhaps urgency traffic carried out the gap, and when UE transferred Idle state to from connected state, network side discharged user's urgency traffic radio bearer.If the user wants to recover the radio bearer of these urgency traffics, then initiate the service request flow process.

2. after user's urgency traffic was finished, perhaps urgency traffic carried out the gap, and when UE transferred Idle state to from connected state, network side discharged user's urgency traffic radio bearer.If this moment, the user was because other reasons, such as CSFB (CS fallback, get back to circuit domain) only set up signaling with network side and be connected, but do not recover the carrying of wireless side, this moment, the user initiated service request flow process request recovery wireless side carrying (radio bearer that comprises urgency traffic and/or non-emergent business).

3. the user is carrying out urgency traffic, and this moment, the radio bearer of urgency traffic existed, but the user has still initiated the service request flow process, wants to recover the carrying of non-emergent business.

The service request flow process is as follows:

E1, UE send service request information to first Mobility Management Entity.

E2, first Mobility Management Entity judge whether to exist urgency traffic not have the wireless side carrying that recovers, if first Mobility Management Entity recovers the wireless side carrying of urgency traffic, otherwise sends service-denial message to subscriber equipment.

Perhaps: the validity (whether the business of promptly judging the user is limited) that first Mobility Management Entity inserts in current region/access technology/turn-on time according to user's signature data verification user, if customer service is limited, then first Mobility Management Entity only recovers user's urgency traffic carrying, and other non-emergent service bearers are not recovered.If the urgency traffic carrying that the user does not exist needs to recover, first Mobility Management Entity sends service-denial message to subscriber equipment.

Carry the limited indication information element of customer service in the service-denial message and/or carry non-emergent service bearer tabulation, after UE receives this message, can wait with APN according to the ARP of carrying and judge which carrying is relevant with urgency traffic, which carrying is uncorrelated with urgency traffic, such as judging whether APN is the APN of urgency traffic, and the non-emergent service bearer state that preserve this locality is set to hang-up/down state, no longer initiates service request.

Following Fig. 6 and Fig. 7 of consulting, introduce UE moves to second Mobility Management Entity from first Mobility Management Entity scene, in this case, UE can be transformed into non-restricted mode from professional restricted mode, perhaps keeps professional restricted mode, and therefore two kinds of implementations are arranged, it is a kind of when UE switches to second Mobility Management Entity, if UE is transformed into non-restricted mode from professional restricted mode, can recovering bearing in handoff procedure, be convenient to the user and carry out business fast; Another kind is: if when UE switches to second Mobility Management Entity, still be in professional restricted mode, need to keep non-emergent service bearer unavailable, avoid operator's unnecessary loss.

First kind of mode is:

F1, first access network element send handoff request message to first Mobility Management Entity.

F2, first Mobility Management Entity send forward direction handoff request message to second Mobility Management Entity.Comprise the limited indication information of customer service in the message, the limited indication information of this customer service can be user's beared information tabulation, the state (Bearer Status) that can comprise each carrying in the tabulation of user's beared information for whether hang up/unavailable.Perhaps: the limited indication information of this customer service is professional limited indication (ServiceRequest Indicator) cell, to notify the second Mobility Management Entity UE limited in the source business, can only carry out particular services such as urgency traffic.

If the F3 gateway changes (promptly this moment, UE inserted second gateway), second Mobility Management Entity sends to second gateway and creates bearing request message.

Carry the limited indication information of customer service in this establishment bearing request message, the limited indication information of customer service can be user's loaded state information or professional limited indication information element.

After F4, second gateway are received and are set up bearing request message, create carrying, to being designated as hang-up/disabled carrying, the state that second gateway should carry is set to hang up/and unavailable, when receiving this carrying related data packets, with data packet discarding, do not send downlink data notification DownLink Data Notification message to second Mobility Management Entity.

Perhaps, in step F 3, if second Mobility Management Entity is preserved user's subscription data, and checking user effectively (that is: user can in current region/access technology/insert in turn-on time).Then in setting up bearing request message, need not carry professional limited indication information, in step F 4, then create carrying according to general establishment carrying step.

Illustrate: second Mobility Management Entity can be in this step, but notifies the second gateway customer service limited indication information in step F 9, perhaps notifies second gateway to recover relevant bearer, does not influence realization of the present invention.

F5, second Mobility Management Entity are that UE creates radio bearer.

F6, second Mobility Management Entity send the forward direction switching response message to first Mobility Management Entity.

F7, after switching is finished, second Mobility Management Entity sends the forward direction handoff completion message to first Mobility Management Entity.

F8, first Mobility Management Entity send to switch to second Mobility Management Entity finishes acknowledge message.

F9, second Mobility Management Entity send to second gateway and upgrade bearing request message UpdateBearer Request.

F10, second gateway send to grouped data network gateway and upgrade bearing request message.

If second Mobility Management Entity does not notify the second gateway customer service limited indication information in step F 3, then can in step F 9, in the renewal bearing request message that second gateway sends, carry the limited indication information of customer service by second Mobility Management Entity.

After second gateway is received the bearer update request message in step F 10, to being designated as hang-up/disabled carrying, the state that second gateway should carry is set to hang up/and unavailable, when receiving this carrying related data packets, with data packet discarding, do not send downlink data notification DownLink Data Notification message to second Mobility Management Entity.

Perhaps, if second Mobility Management Entity is preserved user's subscription data, and checking user effectively (that is: user can in current region/access technology/insert in turn-on time), then in step F 9, do not carry professional limited indication information in the bearer update request message.

Wherein, the implementation of state for hanging up of non-emergent service bearer is set for the grouped data network gateway among the embodiment one, after grouped data network gateway is received message in the step F 10, the state of hanging up carrying is set to available, when receiving the downlink data packet that this carrying is correlated with, no longer abandon, but send on corresponding second gateway.

Perhaps:

If disposed static PCC rule, the state of the door of the non-emergent service related data stream of grouped data network gateway is set to out (open), can be 0 non-emergent service bearer to GBR/MBR, grouped data network gateway can be initiated the bearer update flow process according to the PCC rule.

If disposed dynamic PCC rule, grouped data network gateway can send the session updates request message to PCRF, can carry the recovering bearing indication information element in the message and notify the PCRF customer service no longer limited.After PCRF receives message, open the door of the non-emergent business data flow of user, the state of door is set to out (open), and PCRF sends the session updates response message to grouped data network gateway, carries the new PCC rule of the door state of having revised data flow in the message.After grouped data network gateway is received the session updates response message, the door state of non-emergent business data flow is updated to open, can also initiates carrying interpolation/renewal/deletion flow process according to new PCC rule.

F11, grouped data network gateway send to second gateway and upgrade bearing response message.

F12, second gateway send to second Mobility Management Entity and upgrade bearing response message.

Illustrate: second Mobility Management Entity notifies the recovering bearing flow process of second gateway also can more finish in the new technological process in follow-up position, please refer to F13-F18.

The district changes if the user finds route, and perhaps residing tracking area in the tracking area tabulation of preserving, is not then initiated route district/tracing section updating flow process.

F13, UE send position updating request to second Mobility Management Entity, promptly initiate route district/tracing section updating request.

If F14 second Mobility Management Entity does not have contextual information such as user contracting data or before not in attaching position register/home location server (HLR/HSS) registration, then sends the location update request message request registration and obtain user contracting data.

F15, second Mobility Management Entity send the bearer update request message to second gateway.

F16, second gateway send the bearer update request message to grouped data network gateway.

In step F 15, if second Mobility Management Entity is according to user contracting data, determine that the user still is in the customer service restricted mode, then upgrade and comprise the limited indication information of customer service in the bearing request message.

In the step F 16, after second gateway is received and is upgraded bearing request message, the state of non-emergent service bearer is set to hang up/and unavailable, when receiving this carrying related data packets, with data packet discarding, do not send downlink data notification DownLink Data Notification message to second Mobility Management Entity.

Perhaps, if in step F 15, second Mobility Management Entity is according to user's subscription data, and the checking user is (that is: user can in current region/access technology/insert in turn-on time) effectively, then:

Second Mobility Management Entity sends to second gateway and upgrades bearing request message, carry the not limited indication information of user in this message, the not limited indication information of this user can be that carrying recovers indication, recovers non-emergent service bearer to indicate second gateway.

Perhaps, second Mobility Management Entity sends Resume message to second gateway, can carry the not limited indication information of user in this message, and the not limited indication information of this user can be that the carrying that needs to recover is tabulated.

The state that second gateway is provided with non-emergent service bearer is available, when receiving user's downlink data packet, second gateway is packet discard no longer, can notify second Mobility Management Entity (when user's downlink data face is unavailable) or directly user data is forwarded to second access network element (but user's downlink data face time spent).

If the state that by grouped data network gateway the carrying of non-emergent business is set among the embodiment one be hang up/invalid, perhaps close the door of the data flow of non-emergent service bearer, after then second gateway is received renewal bearing request message or Resume message:

Second gateway sends to grouped data network gateway and upgrades bearing request message, upgrades in the bearing request message and carries the not limited indication information of user, and the not limited indication information of this user can be that carrying recovers indication; Recover non-emergent service bearer with the indication grouped data network gateway.

Perhaps second gateway sends Resume message to grouped data network gateway, carries the not limited indication information of user in this message, and the not limited indication information of this user can be that the carrying that needs to recover is tabulated.

After grouped data network gateway was received message, the state of hang-up carrying was set to available, when receiving the downlink data packet that this carrying is correlated with, no longer abandons, but sends on corresponding second gateway.

Perhaps:

If disposed static PCC rule, the state of the door of the non-emergent service related data stream of grouped data network gateway is set to out (open), and be 0 non-emergent service bearer to GBR/MBR, grouped data network gateway can be initiated the bearer update flow process according to the PCC rule.

F17, grouped data network gateway send to second gateway and upgrade bearing response message.

F18, second gateway send to second Mobility Management Entity and upgrade bearing response message.

If gateway does not change in the handoff procedure, promptly second Mobility Management Entity is connected with first gateway, then behind the execution in step F2, and not execution in step F3 and F4, directly execution in step F5, F6, F7, F8, F9 and F10, wherein,

Second Mobility Management Entity receives that existence is hang-up/disabled carrying in user's beared information tabulation that first Mobility Management Entity sends, perhaps receive professional limited indication information element, then second Mobility Management Entity carries loaded state information in the renewal bearing request message that first gateway sends, and the state of non-emergent service bearer is for hanging up in its loaded state information; Perhaps, carry professional limited indication information element in the renewal bearing request message that second gateway sends, it is limited for using that then second gateway keeps the state of non-emergent service bearer.

If second Mobility Management Entity is preserved user's subscription data, and checking user effectively (that is: user can in current region/access technology/insert in turn-on time), then:

Second Mobility Management Entity sends to first gateway and upgrades bearing request message, carry the not limited indication information of user in this message, the not limited indication information of this user can be that carrying recovers indication, recovers non-emergent service bearer to indicate first gateway.

Perhaps, second Mobility Management Entity sends Resume message to first gateway, carries the not limited indication information of user in this message, and the not limited indication information of this user can be that the carrying that needs to recover is tabulated.

The state that first gateway is provided with non-emergent service bearer is available, when receiving user's downlink data packet, gateway is packet discard no longer, can notify second Mobility Management Entity (when user's downlink data face is unavailable) or directly user data is forwarded to second access network element (but user's downlink data face time spent).

If the state that by grouped data network gateway the carrying of non-emergent business is set among the embodiment one be hang up/invalid, perhaps close the door of the data flow of non-emergent service bearer, after then first gateway is received renewal bearing request message or Resume message:

First gateway sends to grouped data network gateway and upgrades bearing request message, upgrades in the bearing request message and carries the not limited indication information of user, and the not limited indication information of this user can be that carrying recovers indication; Recover non-emergent service bearer with the indication grouped data network gateway.

Perhaps first gateway sends Resume message to grouped data network gateway, carries the not limited indication information of user in this message, and the not limited indication information of this user can be that the carrying that needs to recover is tabulated.

After grouped data network gateway was received message, the state of hang-up carrying was set to available, when receiving the downlink data packet that this carrying is correlated with, no longer abandons, but sends on corresponding first gateway.

Perhaps:

The second way:

G1, UE send position updating request, i.e. route district/tracing section updating request to second Mobility Management Entity.

After G2, second Mobility Management Entity are received route district/tracing section updating request, send context request message, ask user context information, comprised user's beared information in the contextual information to first Mobility Management Entity.The state (bearer status) that has comprised each carrying in the beared information, according to loaded state, second Mobility Management Entity can learn whether carrying is hung up/unavailable.Perhaps: first Mobility Management Entity carries professional limited indication information element in context response information, notifies this UE of second Mobility Management Entity limited in the source business, can only carry out particular services such as urgency traffic.

If there is hang-up/disabled carrying in G3 user, and second Mobility Management Entity is preserved user's subscription data information, second Mobility Management Entity checking user is in current region/access technology/whether can insert in turn-on time, if, customer service before is restricted not to be existed, then:

If gateway changes (be after UE switches second Mobility Management Entity connect second gateway), then second Mobility Management Entity sends to second gateway and creates bearing request message.

If gateway does not change (be after UE switches second Mobility Management Entity connect first gateway), second Mobility Management Entity sends to first gateway and upgrades bearing request message, carry carrying in the message and recover indication information element, indicate first gateway to recover the carrying that is suspended, perhaps: Resume message can also take place to first gateway in second Mobility Management Entity, can carry the carrying tabulation of recovery in the message, the beared information of notifying first gateway to recover.After first gateway was received and upgraded bearing request message, the state of preserving relevant bearer was set to available.When receiving user-dependent downlink data packet, the first affair gateway can be notified second Mobility Management Entity (user's downlink user face is unavailable) or directly forward the data to corresponding access network element (user's downlink user face is available).

Perhaps, if do not preserve user contracting data in second Mobility Management Entity, can't verify user's validity, can: if gateway changes, hang-up/disabled carrying second Mobility Management Entity is carried professional limited indication information element to setting up of second gateway transmission in the bearing request message, indicate this carrying of second gateway to be in hang-up/down state temporarily.Second gateway is set up carrying earlier, and the state that non-emergent service bearer is set again is for hanging up; If gateway does not change, then send the bearer update request message to second gateway.

G4, second gateway or first gateway send to grouped data network gateway and upgrade bearing request message or Resume message.

Wherein, the state that non-emergent service bearer is set for the grouped data network gateway among the embodiment one is the mode of hanging up or closing the door of non-emergent business data flow, in this step, after grouped data network gateway is received and is upgraded bearing request message or Resume message, the state of former hang-up carrying is set to available, when receiving the downlink data packet that carrying is correlated with, no longer abandon, but send to corresponding gateway.

Perhaps:

If disposed static PCC rule, the state of the door of the non-emergent service related data stream of grouped data network gateway is set to out (open); To GBR/MBR is 0 non-emergent service bearer, and grouped data network gateway can be initiated the bearer update flow process according to the PCC rule.

G5, grouped data network gateway send the renewal bearing response message to second gateway or second gateway.

G6, second gateway send to second Mobility Management Entity and set up bearing response message, and perhaps second gateway sends to second Mobility Management Entity and upgrades bearing response message.

G7, second Mobility Management Entity send the position to UE and upgrade acceptance, be that route district/tracking area is accepted message, can carry carrying in the message and recover indication information element, no longer limited with the indication customer service, perhaps carry the carrying that needs to recover and tabulate, UE recovers indication information element according to carrying and determines that customer service is no longer limited, and the state of non-emergent service bearer is set to available, perhaps, the indicated carrying that need recover in the carrying tabulation that UE recovers to recover.When the user wants to carry out business, can use signaling process request resource such as resource allocation/service request.

When following description was carried out urgency traffic as the user, the user who revises or delete on the access network element was switched restriction, makes the user normally to switch:

H1, gateway are initiated dedicated bearing to Mobility Management Entity and are set up request (Create DedicatedBear Request).

This Mobility Management Entity can be second Mobility Management Entity.

H2, Mobility Management Entity send the SAE carrying to access network element (such as second network element that is connected with second Mobility Management Entity) and set up request (SAE Bear Setup Request)/session management request (Session Management Request).

H3, access network element and UE set up radio bearer alternately.

H4, access network element send the SAE carrying to Mobility Management Entity and set up response (SAE Bear SetupResponse).

H5, Mobility Management Entity know that this carrying is urgency traffic carrying, send user's context to access network element and revise request, in the request user are switched restriction and make amendment and delete, and guarantee that urgency traffic can switch to limited zone or access technology.

H6, access network element deletion user's switching restriction or modification user's switching restriction, such as having kept the roaming restriction, deleted region limits, access technology restriction and restriction turn-on time, and sent user's context modification response message to Mobility Management Entity.

H7, UE send direct-sending message to access network element.

H8, access network element are to Mobility Management Entity transparent transmission direct-sending message, and this direct-sending message is the session management response message.

H9, Mobility Management Entity send dedicated bearing to gateway and set up response message.

H10, after urgency traffic is finished, Mobility Management Entity sends the switching restriction of the user on the information updating access network element, this message can be that initial context is set up request (Initial Context SetupRequest) message, also can be that the switching restriction of carrying the user in request (UE Context Modification Request) this message set up in the UE context.

H11, access network element send initial context to Mobility Management Entity and set up response (InitialContext Setup Response) or UE contextual modifications response (UE Context ModificationResponse).

The key point of this part is: after Mobility Management Entity knew that the carrying of foundation is the urgency traffic carrying, deletion or the switching of revising on the access network element limited, and avoided causing urgency traffic to interrupt owing to switch to confined area.This part is not limited in dedicated bearing and sets up flow process, can also comprise following sight, for example: in the Client-initiated PDN linking request flow process, if the user has carried urgency traffic APN, Mobility Management Entity knows that the user need carry out urgency traffic, and this moment, Mobility Management Entity also can be initiated the modification process of user's context.After urgency traffic was finished, Mobility Management Entity added or revises switching restriction on the access network element, guarantees that the user can only carry out business under situation about being authorized to.

Effective effect of this part is: when UE carries out urgency traffic, the user who revises or delete on the access network element is switched restriction, make the user normally to switch: such as when the user in the urgent urgent telegram of E-UTRAN network words, and user's access is restricted to the user and can not inserts UTRAN.This moment, the wireless signal of E-UTRAN was bad, and the signal of UTRAN is better, but owing to switch restriction, the user can not switch to the UTRAN network, causes emergency call call drop/quality to descend probably.If Mobility Management Entity is cancelled this switching restriction at this moment, the user just can switch to the UTRAN network, improves quality of service.
