Description

Method for processing resource and device that a kind of network switches

Technical field

The present invention relates to a kind of method for processing resource and device, method for processing resource and device that especially a kind of network switches belong to communication technical field.

Background technology

Because in the current wireless architectures of communication networks, have 3GPP (third generation partner program) network and non-3GPP network simultaneously, UE need switch between 3GPP network and non-3GPP network.Before switching was finished, the network of carrying UE business was called the source network; After switching was finished, the professional network of carrying user terminal (User Equipment is called for short UE) was called the target side network.Switch to example from 3GPP network (source network) to non-3GPP network (target side network) with UE, after execution is switched, guarantee that the business of UE is continuous.Detailed process is as follows: UE successfully adheres at the target side network, the target side network creation is to the bearing resource of this UE, and with UE at source grouping of network data network gateway (PacketData Network Gateway, the wireless access type of the bearing resource abbreviation PGW) changes the wireless access type of target side network into, when PGW finds that this UE is when the wireless access type of the bearing resource of source network changes, PGW initiates the resource release flow at the source network, thereby deletion UE is in the resource of source network.

No matter UE switches to non-3GPP network or switches to the 3GPP network from non-3GPP network from the 3GPP network, all need to adhere in the success of target side network and finish switching by UE, but source network in the prior art (3GPP network or non-3GPP network) can't know that whether UE is limited at target side network (non-3GPP network or 3GPP network), can't know also whether UE successfully adheres at the target side network.Therefore, if UE (for example, UE can not find proper cell and is stationed) when target side is network limited, then the target side network only allows this UE to carry out urgency traffic at the target side network, must not carry out other Packet data service (PS) business.Therefore, UE's can't discharge resource at the source network.Thereby caused the waste of the bearing resource of source network.

UE switches to non-3GPP network or UE switches to the 3GPP network from non-3GPP network from the 3GPP network, in the prior art, UE is after target side network (non-3GPP network or 3GPP network) asset creation is all successful, and PGW just can initiate the release of source resource.If UE is in 3GPP and non-3GPP network switching process, if owing to reasons such as resource shortage or capacity of equipment restriction cause UE all not create successfully at the Internet resources of target side (is that UE successfully creates a part of resource at the target side network, perhaps UE all creates failure in the resource of target side network), this moment, PGW can't normally discharge the resource of UE at the source network.Therefore, UE can't be released at the source network.Thereby caused the source waste of network resources.

Deletion is in the resource relevant with user terminal of source network, and this resource mainly is meant and is based upon resource such as PDN connection on the source network entity.

Upgrade the information relevant among HSS and the AAA with user terminal, these information spinners to be meant with user terminal in the source network and the APN PDN join dependency (APN) and PGW information etc.

The resource information of the source network in the deletion user terminal, the resource information in the user terminal mainly is the resource for the source network of bearer service.

Wherein, the source network can be 3GPP network and non-3GPP network, and same, the target side network also can be 3GPP network and non-3GPP network.

In the present embodiment, the entity that specifically receives the source network of first Indication message can be an entity of being responsible for access control, for the 3GPP network, can be MME.For non-3GPP network, can be non-3GPP gateway or HRPD AN.The concrete network entity that receives first Indication message can also be a grouped data network gateway.

Above-mentioned steps 10 is different with the type of target side network according to the source network, may have following several situation:

1) the source network is non-3GPP network, the target side network is the 3GPP network, step 10 can be specially: MME is known the limited-service of user terminal at the 3GPP network in the access 3GPP of user terminal network development process, sends first indication information by HSS and AAA to non-3GPP gateway.Perhaps MME sends first indication information or MME through HSS and/or AAA to grouped data network gateway (PGW) and sends first indication information or MME directly sends first indication information to PGW through gateway SGW to PGW.

2) the source network is the 3GPP network, the target side network is non-3GPP network, step 10 can be specially: non-3GPP gateway inserts in the non-3GPP network development process at user terminal, knows the limited-service of user terminal at non-3GPP network, sends first indication information by HSS and AAA to MME.Perhaps non-3GPP gateway sends first indication information or non-3GPP gateway through HSS and/or AAA to grouped data network gateway (PGW) and sends first indication information or non-3GPP gateway sends first indication information to PGW through SGW to PGW.

4) the source network is the 3GPP network, the target side network is the CDMA2000 network of non-3GPP network, step 10 can be specially: HRPD AN inserts in the non-3GPP network development process at user terminal, knows limited-service or the asset creation failure of user terminal at non-3GPP network; HRPD AN sends first indication information to MME.

The situation that in the source network, has urgency traffic for user terminal, can be specially in step 10: insert in the target side network development process at user terminal at the target side network, know limited-service or the asset creation failure of user terminal, and there is urgency traffic in user terminal in the source network at the target side network; In the resource of target side network creation urgency traffic, and send first indication information to the source network.

1) the source network is non-3GPP network, and the target side network is the 3GPP network, and step 10 can be specially:

MME inserts in the 3GPP network development process at user terminal, knows limited-service or the asset creation failure of user terminal at the 3GPP network, and has urgency traffic at the source network;

Create the resource of the urgency traffic of 3GPP network;

MME sends first indication information to non-3GPP gateway, and wherein, MME can send first indication information to non-3GPP gateway by HSS and AAA, also can send first indication information to non-3GPP gateway by SGW and PGW.

In addition, can further include in the above-mentioned steps 10: MME indicates SGW and/or the PGW subscriber terminal service is limited or the asset creation failure, like this, when adopting the PMIP agreement between SGW and the PGW, SGW just no longer carries out the asset creation of non-emergent business and the data forwarding of non-emergent business; When adopting the GTP agreement between SGW and the PGW, PGW just no longer carries out the asset creation of non-emergent business and the data forwarding of non-emergent business.

2) the source network is the 3GPP network, and the target side network is non-3GPP network, and step 10 can be specially:

Non-3GPP gateway inserts in the non-3GPP network development process at user terminal, knows limited-service or the asset creation failure of user terminal at non-3GPP network, and has urgency traffic at the source network;

Create the resource of the urgency traffic of non-3GPP network;

Non-3GPP gateway sends first Indication message to MME.Wherein, non-3GPP gateway can send to PGW with first Indication message earlier, and PGW is transmitted to SGW, and SGW sends first indication information to MME again.Non-3GPP gateway also can send first indication information by HSS and AAA to MME with first indication information.

In addition, can further include in the above-mentioned steps 10: MME indicates SGW and/or the PGW subscriber terminal service is limited or the asset creation failure, and like this, SGW and/or PGW just no longer carry out the asset creation and the data forwarding of non-emergent business.

3) the source network is the CDMA2000 network of non-3GPP network, and the target side network is the 3GPP network, and step 10 can be specially:

Create the resource of the urgency traffic of 3GPP network;

MME sends first indication information to HRPD AN.

4) the source network is the 3GPP network, and the target side network is the CDMA2000 network of non-3GPP network, and step 10 can be specially:

HRPD AN inserts in the non-3GPP network development process at user terminal, knows limited-service or the asset creation failure of user terminal at non-3GPP network, and has urgency traffic at the source network;

Create the resource of the urgency traffic of non-3GPP network;

HRPD AN sends first indication information to MME.

In the present embodiment, in the handoff procedure of 3GPP network and non-3GPP network, when UE when the target side network adheres to, if the entity of target side network is found the limited-service at this UE, then generate one first indication information, and send to the entity or the grouped data network gateway of source network, thereby notice source network or grouped data network gateway are released to the Internet resources that this UE sets up.Reduced like this in the prior art, because the target side network is under normal establishing resource situation, and the waste in the resource of source network that causes.

Embodiment two

The flow chart of the method for processing resource that the network that Fig. 3 provides for the embodiment of the invention two switches as shown in Figure 3, comprising:

Step 20, obtain the mobility limitation information of user terminal.Before network switched, the source network obtained the mobility limitation information of user terminal from AAA or HSS.Mobility limitation information can send to mobility limitation information the entity of source network as subscription data by HSS and AAA at UE when the source network carries out Location Registration.Mobility limitation information specifically is meant user terminal limited-service in which zone.In addition, need to prove that in an embodiment of the present invention, HSS can separate setting with AAA, also can be wholely set and be HSS/AAA.Wherein, AAA has comprised the AAA Proxy (AAA acting server) under roaming scence and the AAA Server (aaa server) of ownership place.

The relevant information of the mobility limitation information of step 21, the network based user terminal of source and target side network is known the limited-service of user terminal at the target side network.Wherein, the relevant information of target side network can be obtained by Attach Request message in the process of carrying out the network switching.The target side network relevant information can be the position area information etc. of target side network of type information, the access of target side network.Mobility limitation information refers to user terminal in some regional limited-service information, such as user terminal limited-service in the certain location district, and perhaps user terminal limited-service or the like relevant information in specific Access Network (e-UTRAN or CDMA).The target side network information refers to the Location Area Identification of the target side network that reported by the source Access Network in the handoff procedure or the target side network informations such as access network type of target side network.If mobility limitation information is the relevant information in lane place, then the target side network information is a location area information; If mobility limitation information is an Access Network side information, then the target side network identity is information such as access network type.Can judge that in conjunction with these two information source networks whether UE is in target survey grid network limited-service.

The resource of the source network of step 22, release user terminal.

The source network can be 3GPP network and non-3GPP network, and same, the target side network also can be 3GPP network and non-3GPP network.

In the present embodiment, knowing that specifically user terminal can be an entity of being responsible for access control at the entity of the source network of the limited-service of target side network, for the 3GPP network, can be MME.For non-3GPP network, can be non-3GPP gateway or HRPD AN.

Above-mentioned steps 22 can be specially: deletion is in the resource relevant with user terminal of source network; Upgrade the information relevant among HSS and the AAA with user terminal; The resource information of the source network in the deletion user terminal.

Present embodiment preferably is applied in to be optimized in the scene of switching, and according to optimizing in the handoff scenario, the source network is different with the type of target side network, may have following situation:

1) when the source network was CDMA2000 network in the non-3GPP network, the target side network was the situation of 3GPP network:

Step 20 can be specially: HRPD AN obtains the mobility limitation information of user terminal from AAA;

Step 21 can be specially: when HRPD AN receives user terminal behind the Attach Request message that the 3GPP network adheres to, HRPD AN is known the limited-service of user terminal at the target side network according to mobility limitation information.

2) the target side network is the CDMA2000 network of non-3GPP network, and the source network is the 3GPP network:

Step 20 can be specially: MME obtains the mobility limitation information of portable terminal from HSS;

Step 21 can be specially: when MME receives user terminal behind the Attach Request message that the CDMA2000 network adheres to, MME is known the limited-service of user terminal at the target side network according to mobility limitation information.

In the present embodiment, before network switched, the entity of source network had just been known the mobility limitation information of UE in the target side network.Like this when the entity of source network has known that network switch to take place,, just can directly judge whether UE exists limited-service in the objective network side situation according to these mobility limitation information.If the result who judges is the limited-service in the objective network side, just can directly initiate the flow process of releasing bearing resource at the source network.Reduced like this in the prior art, because the target side network can't normally create under the bearing resource situation, and the waste at the bearing resource of source network that causes.In addition, compare with embodiment one, also not needing the target side network to send special is the indication information of releasing network resources.

Embodiment three

The signaling process figure of the method for processing resource that the network that Fig. 4 provides for the embodiment of the invention three switches.Scene shown in Figure 4 is: UE switches to the 3GPP net at non-3GPP network; UE does not have urgency traffic in non-3GPP network.As shown in Figure 4, comprise the steps:

Step 101, UE carry out business at non-3GPP network, wherein do not comprise urgency traffic.

Step 102, UE find the 3GPP network insertion, satisfy the switching flow of initiating to switch to from non-3GPP network the 3GPP network.This switching flow adheres to (Handover Attach) flow process by UE initiation switching to be realized.

Step 103, UE send to adhere in request (Attach Request) message and carry, and wherein, type of attachment (Attach Type) is designated as to switch adheres to (Handover Attach).

Carry out authorizing procedure between step 104, UE, MME, the HSS/AAA.In this process, MME judge UE current do not exist urgency traffic and UE current in the 3GPP network limited-service, so MME does not allow UE to be linked into the 3GPP network.MME obtains the APN and the PGW information of current business of carrying out from HSS/AAA, if this APN itself is exactly the APN of urgency traffic, just then MME can Direct Recognition to go out the business relevant with this APN be urgency traffic.

Step 105, MME send notice request (Notify Request) message to HSS/AAA, carry resource (Detach for non-3GPP) indication information that discharges non-3GPP network in this message, this information is used for notifying HSS to initiate to discharge (Detach) flow process at the bearing resource of non-3GPP network UE, and UE is in non-3GPP network of network resource in deletion.Can also indicate HSS/AAA to initiate in non-3GPP network release (Detach) flow process to the bearing resource of this UE, the Internet resources of deletion UE in non-3GPP network with independent separation indication (Detachindication) message except in this message, increasing resource (Detach for non-3GPP) indication information that discharges non-3GPP network.

After step 106, HSS receive resource (Detach fornon-3GPP) indication information of the non-3GPP network of release that MME sends, satisfy to send to separate and indicate (Detach indication) message to give AAA.If UE roams in non-3GPP network, the aaa server of ownership place will separate indication (Detachindication) message and send to AAA Proxy (AAA acting server), and AAA Proxy sends to separate and indicates (Detach indication) message to send to non-3GPP gateway (being non-roaming scene shown in the figure).The non-3GPP gateway here can be the non-3GPP IP IAD of MAG, ePDG, ASN GW or the like.Above-mentioned separation (Detach) flow process is adopting S2a (interface between non-3GPP IP IAD and the PGW) and S2b (interface between ePDG and the PGW) scene all to be suitable for.

If adopting under S2c (interface between UE and the PGW) scene, aaa server of ownership place (non-roaming scene) or AAA Proxy (roaming scence) send Session Termination (session termination) message and give PGW, the PDN that notice PGW deletion is relevant with this UE connects, situation in not shown being somebody's turn to do among Fig. 5.

After step 107, non-3GPP gateway are received the DetachIndication message of AAA Server or AAA Proxy transmission, then send Proxy Binding Update (Binding Update) message, carry Lifetime (life cycle)=0 and APN (access point name in the message, be called for short APN) and user ID, this message is used to indicate PGW to delete the relevant PDN of this UE and connects.

After step 108, PGW receive above-mentioned Proxy Binding Update message, not deleting the relevant PDN of this UE that sets up on PGW immediately connects, but send the AAA Server (under the roaming scence) that Update PDN GW Address (upgrading the PGW address) message is given the AAA Server of ownership place or sent to ownership place by AAA Proxy, with APN and the PGW information in the AAA Server deletion of the indication ownership place PDN connection relevant with this UE, after the AAA Server of ownership place carried out deletion action, notice HSS also carried out corresponding deletion action.After the PDN connection relevant with this UE of writing down among the HSS is deleted, promptly finished the registration process of UE in HSS.After deletion was finished, HSS/AAA notified PGW.

The carrying Session Resources of step 109, PGW deletion and this PDN join dependency connection, the transmission binding is replied (Proxy Binding Ack) message and is given non-3GPP gateway, carries Lifetime=0 and user ID, identifies PDG and has finished the deletion that PDN connects.

Step 110, non-3GPP gateway are deleted the bearing resource of this UE in non-3GPP network, send then to separate to reply (Detach Ack) message to HSS/AAA.

After step 111, HSS/AAA receive that (Detach Ack) replied in separation, know that UE is all deleted at the bearing resource of non-3GPP network, send message informing response (Notify Response) then or separate and reply this UE of (Detach Ack) message informing MME and finish in the bearing resource deletion of non-3GPP network.

Step 112, MME in notified response (Notify Response) or separate reply (DetachAck) message after, send message attachment refusal (Attach Reject) message and give UE, notice UE is rejected in the request of adhering to of 3GPP network, the indication information at the bearing resource of non-3GPP network that can carry in this message that resource deletion indication information or UE limited-service indication information or other can indicate that UE deletion UE sets up.By adhering to the indication information that carries in refusal (Attach Reject) message, UE deletes all bearing resources on non-3GPP network on it.The indication information of the Internet resources on the network side indication UE deletion UE also can be indicated by other particular messages except carrying by adhering to refusal (Attach Reject) message.

The method of this deletion source resource (is UE switches to limited-service from the source of non-limited-service a target side except applying to above-mentioned scene, optionally, UE is carrying out urgency traffic), this method is equally applicable to UE switches to the target side of non-limited-service from the source of non-limited-service scene, optionally, this UE is in the asset creation failure (comprising all asset creation failures or the failure of a part of asset creation) of target side network, for example one or more PDN connects the foundation failure, perhaps load creating failure, MME is known the asset creation failure (comprising all asset creation failures or the failure of a part of asset creation) of UE.Under this scene, same MME can send to non-3GPP gateway by HSS and/or AAA and be used to notify the indication information that discharges non-3GPP Internet resources, non-3GPP gateway is initiated deletion source resource flow process according to described indication information, and for example attachment removal flow process of described flow process, carrying discharge flow process or the PDN connection discharges flow process etc.

In the present embodiment, UE does not exist under the situation of urgency traffic in non-3GPP network, when UE at non-3GPP network in the handoff procedure of 3GPP network, though UE adheres to failure in the 3GPP network, but, by the MME in the 3GPP network after judging the limited-service of UE, the Detach fornon-3GPP indication information that generates, the bearing resource of having initiated the source network discharges flow process, thereby reduced because the 3GPP network can't normally created under the bearing resource situation, and the waste of the bearing resource on non-3GPP network that causes.

Embodiment four

The signaling process figure of the method for processing resource that the network that Fig. 5 provides for the embodiment of the invention four switches.Scene shown in Figure 5 is: UE switches to non-3GPP net at the 3GPP network; UE does not have urgency traffic in the 3GPP network.As shown in Figure 5, comprise the steps:

Step 201, UE carry out business at the 3GPP network, wherein do not comprise urgency traffic.

Step 202, UE find non-3GPP network insertion, are initiated to the switching flow of non-3GPP network.

Step 203, UE and non-3GPP gateway and HSS/AAA carry out authentication and identifying procedure.From HSS/AAA, obtain APN and PGW address in this process.Under the roaming scence, the aaa server of AAA Proxy by ownership place obtains APN from HSS and PGW is right.Non-3GPP gateway judges that the UE current service is limited, and does not have urgency traffic, so authentication and authentication are not passed through.Wherein non-3GPP gateway can right and wrong 3GPPI P IAD or gateways such as ePDG or other MAG.

Step 204, non-3GPP gateway sends to PGW and separates Indication message, PGW again to HSS/AAA (if UE is under roaming state, then send to AAA Proxy earlier, AAA Proxy sends to the aaa server of ownership place again) send and separate indication (Detach indication) message, carry resource (the Detach for 3GPP) indication information that discharges the 3GPP network in this message, aaa server indication HSS initiates the attachment removal flow process at the 3GPP network, delete Internet resources or the non-3GPP gateway of UE in the 3GPP network with this and directly send and separates Indication message, carry resource (the Detach for 3GPP) indication information of release 3GPP network in this message to AAA and HSS.

Step 205, HSS/AAA send to MME and separate indication (Detach indication) message indication MME initiation Detach flow process.

Step 206, MME initiate the bearing resource of deletion UE at the 3GPP network, and after the resource deletion, MME notifies HSS/AAA.

Step 207, HSS/AAA send to separate and reply (Detach Ack) message to PGW, PGW is to non-3GPP gateway, notifies the deleted or HSS/AAA of the resource of non-this UE of 3GPP gateway in the 3GPP network to send to separate and replys (Detach Ack) message to non-3GPP gateway.

Step 208, non-3GPP gateway send resource deletion indication (Resource Delete indication) message and give UE, can carry the indication information of Internet resources that resource deletion indication information or UE limited-service indication information or other can be indicated the 3GPP of the foundation on the UE deletion UE in this message.

The method of this deletion source resource (is UE switches to limited-service from the source of non-limited-service a target side except applying to above-mentioned scene, optionally, UE is carrying out urgency traffic), this method is equally applicable to UE switches to the target side of non-limited-service from the source of non-limited-service scene, optionally, this UE is in the asset creation failure (comprising all asset creation failures or the failure of a part of asset creation) of target side network, for example one or more PDN connects the foundation failure, the asset creation failure (comprising all asset creation failures or the failure of a part of asset creation) of UE is known in perhaps load creating failure, non-3GPP gateway.Under this scene, same non-3GPP gateway is used to notify the indication information that discharges the 3GPP Internet resources except sending to MME by HSS and/or AAA.Perhaps non-3GPP gateway can to PGW and/or, HSS and/or AAA send to MME and be used to notify the indication information that discharges the 3GPP Internet resources, MME is according to described indication information start flow deletion source resource, and for example attachment removal flow process of described flow process, carrying discharge flow process or PDN connects release flow process etc.。

In the present embodiment, UE does not exist under the situation of urgency traffic in the 3GPP network, when UE at the 3GPP network in the handoff procedure of non-3GPP network, though UE adheres to failure in non-3GPP network, but, by the non-3GPP gateway in the non-3GPP network after judging the limited-service of UE, generate Detachfor non-3GPP indication information, the bearing resource of having initiated the source network discharges flow process, thereby reduced because the 3GPP network can't normally created under the bearing resource situation, and the waste of the bearing resource on non-3GPP network that causes.

Embodiment five

The signaling process figure of the method for processing resource that the network that Fig. 6 provides for the embodiment of the invention five switches.Scene shown in Figure 6 is: UE switches to the 3GPP net at non-3GPP network, and there is urgency traffic in UE in non-3GPP network.

As shown in Figure 6, comprise the steps:

Step 301, UE carry out business at non-3GPP network, comprising urgency traffic and non-emergent business.

Step 302, UE satisfy the switching flow of initiating to switch to from non-3GPP 3GPP according to detecting the 3GPP network insertion, and this switching flow adheres to (Handover Attach) flow process by UE initiation switching to be realized.Following step 303-step 317 is to switch adheres to (Handover Attach) flow process.

Step 303, UE send to MME and adhere to request (Attach Request) message, carry information such as Attach Type and urgent call indication information in the message, type of attachment (Attach type) is adhered to (Handover Attach) for switching, and the urgent call indication information represents that there is urgency traffic in UE in non-3GPP network.

Carry out authorizing procedure between step 304, UE, MME, the HSS.Because the current urgency traffic that exists of UE, so though UE is current in 3GPP network limited-service, the 3GPP network still allows UE to insert.

Step 305, MME send the position and upgrade (Update location) message to the HSS/AAA server, and the address information of registration MME is to HSS.

Step 306, HSS/AAA send the position and upgrade affirmation (Update Location Ack) message to MME, carry IMSI and CAMEL-Subscription-Information (Subscription data) in the message, CAMEL-Subscription-Information comprises the subscription data that the PDN of UE in non-3GPP network connects, to APN and PGW address, APN and PGW that urgent call is relevant also comprise wherein comprising many.

Step 307, MME send default bearer request to create (Create Default BearerRequest) message to SGW, can carry urgency traffic relevant APN and PGW information in this message, SGW gives this urgency traffic relevant PGW this forwards, this step is used for the default bearer resource that is connected with the urgent PDN of PGW information creating according to the relevant APN of urgency traffic, and notifies PGW this UE limited-service by this process.Carry relevant APN of urgent call and PGW information, wireless access type (Radio Access Type in this message, abbreviation RAT), indication message, limited-service indication information, SGW address and Tunnel Identifier information such as (Tunneling ID are called for short TEID).Wherein, RAT type (RATType) information is used for indicating current this PDN to be connected the 3GPP network.Switch indication (HandoverIndication) information and be used to represent the current switching flow that switches to 3GPP for non-3GPP.APN and PGW information that APN is relevant with urgent call with the PGW information representation.SGW address and TEID represent that SGW is that PGW is the data downstream address and the Tunnel Identifier of this load creating.

Situation shown in the figure is to be the situation of GTP (GPRS Tunnel Protocol) agreement between SGW and the PGW, and SGW transmits and send default bearer request to create message to PGW, and PGW knows that according to the limited-service indication information UE current service is limited.Therefore, PGW can not initiate non-emergent service resources establishment and/or data forwarding.In addition, if between SGW and the PGW be the situation (not shown) of PMIP (proxy-mobile IP) agreement, then SGW knows that according to the limited-service indication information that MME sends the UE current service is limited, and therefore, SGW can not initiate non-emergent service resources and create and/or data forwarding.Present embodiment is being that the GTP agreement illustrates between SGW and the PGW.

After UE leaves the limited-service zone, MME will send bearer update request (Update BearerRequest) message or other message is given SGW or PGW, carry the indication information of normal service in the message, indication SGW or PGW can transmit non-emergent business datum and can carry out non-emergent service resources and create.

It is switching flow that step 308, PGW judge current according to indication message, satisfies to PCRF and obtains PCC (strategy and charging) rule, and the PCC rule downloading that PCRF is relevant with this UE is given PGW.This step is optional, and PGW also can utilize the rule that self disposes to initiate following load creating.

Step 309, PGW create according to the dedicated bearing that the PCC rule of obtaining from PCRF is initiated default bearer and urgent call, because PGW has obtained the limited-service indication information in step 307, create thereby make PGW can not initiate other professional resource bearings.This process has been created the carrying between UE and eNodeB and SGW and the PGW.

Step 310, MME send bearer update request (Update Bearer Request) message to SGW, carry eNodeB address and TEID and indication message that eNodeB creates in step 309 in the message.

Step 311, SGW send the bearer update request message to PGW according to the indication message in the step 310, carry indication message in the message, and notice this default bearer of PGW and dedicated bearing can guarantee that packet forwards the 3GPP side to from non-3GPP.

Step 312, PGW send bearer update response (Update Bearer Response) to SGW.

Step 313, SGW send bearer update response (Update Bearer Response) to MME.

Step 314, because UE limited-service in the 3GPP network, therefore, MME sends notice request (Notify Request) message and gives HSS/AAA, carry resource (the Detach for non-3GPP) indication information that discharges non-3GPP network in the message, indication HSS initiates the Detach flow process of non-3GPP network, thereby discharges the bearing resource of UE at non-3GPP network.

Step 315, HSS/AAA send push-notification-answer (Notify Response) message to MME, and notice MME initiates the Detach flow process of non-3GPP network.

Step 316, MME return to UE and adhere to acceptance (Attach Accept) message, carry temporary mark and tracking area identification and limited-service indication information that the 3GPP network distributes to UE.After UE receives this indication information, the bearing resource of setting up among the deletion UE at non-3GPP network.This information also can send to UE by MME by other message.

Step 314,315 and the not free sequencing of step 316.Step 316 also can be carried out after step 321.

After step 317, HSS receive resource (Detach fornon-3GPP) indication information of the non-3GPP network of release that MME sends, satisfy to send and separate indication (Detach indication) to aaa server, if UE roams at non-3GPP network, the aaa server of ownership place will separate indication (Detach indication) message and send to AAA Proxy, AAA Proxy sends to separate and indicates (Detach indication) message to send to non-3GPP gateway (being non-roaming scene shown in the figure), and the non-3GPP gateway here can be MAG, ePDG etc.Above-mentioned separation (Detach) flow process is S2a (interface between non-3GPP IP access and the PGW) and S2b (interface between ePDG and the PGW) scene.Under S2c (interface between UE and the PGW) scene, AAA Server (non-roaming scene) or AAA Proxy (roaming scence) send Session Termination message to PGW, and notice PGW deletes the relevant PDN of this UE and connects.When PGW connects at deletion PDN, discharged the UE that on PGW, sets up in non-3GPP network of network resource.And the wireless access type of the bearing resource that urgency traffic is correlated with is EUTRAN (UMTS of evolution (universal mobile telecommunications system) terrestrial access network), so the bearing resource that the PDN of this urgency traffic is connected on the 3GPP network can be not deleted with separation (Detach) flow process of non-3GPP network.By separating (Detach) flow process, UE can be deleted entirely in the resource of non-3GPP network, wherein comprises urgency traffic resource and non-emergent service resources.

After step 318, non-3GPP gateway are received separation indication (Detach indication) message of aaa server or AAA Proxy transmission, send Binding Update (Proxy Binding Update) message and give PGW, carry Lifetime (life cycle)=0 and APN and user ID in the message, this message indication PGW deletes the relevant PDN of this UE and connects.

Step 319, PGW send and upgrade the aaa server that PGW address (Update PDN GW Address) message is given the aaa server of ownership place or transferred to ownership place by AAA Proxy, the aaa server deletion of indication ownership place and the APN and the PGW information of above-mentioned PDN join dependency, the aaa server notice HSS of ownership place carries out Data Update.After all so non-emergent relevant PDN connections were deleted, only remaining urgency traffic is relevant among the HSS APN and PGW were right.

Step 320, PGW delete all carrying sessions with this PDN join dependency connection, and the transmission binding is replied (Proxy Binding Ack) message to non-3GPP gateway, carry Lifetime (life cycle)=0 and user ID in the message, this message identifier PGW has deleted relevant PDN and has connected.Non-3GPP gateway is received the bearing resource of deleting all non-emergent business of setting up after this message again in non-3GPP network.

Step 321, HSS are updated to MME with up-to-date APN and PGW information by inserting subscription data (InsertSubscriber Data) flow process, and MME deletes the relevant PDN link information of all non-emergent business.

Be with the foregoing description four and embodiment five differences, because there has been urgency traffic in UE at non-3GPP network, after switching, though non-emergent business is restricted, but the 3GPP network still will be created the related resource of urgency traffic, also will notify non-3GPP network to discharge the bearing resource of non-emergent business by the mode that sends indication simultaneously.So both guaranteed the normal foundation of urgency traffic, also discharged UE timely at the relevant bearing resource of the non-emergent business of non-3GPP network, thus reduce the bearing resource waste in the non-3GPP network.

Embodiment six

The signaling process figure of the method for processing resource that the network that Fig. 7 provides for the embodiment of the invention six switches.Scene shown in Figure 7 is: UE switches to the 3GPP net at non-3GPP network, and there is urgency traffic in UE in non-3GPP network.

As shown in Figure 7, the step 401-step 413 of present embodiment is identical with step 301-step 313 among the embodiment five, does not repeat them here.

Step 414, after the urgency traffic asset creation is finished, MME sends to UE and adheres to acceptance (AttachAccept) message.

Step 415, PGW are according to the UE limited-service indication information of knowing in the step 407 (being the step 307 among the embodiment six), send and separate indication (Detach Indication) message to non-3GPP gateway, carry the indication information of the resource (Detach for non-3GPP) that discharges non-3GPP network in the message, by this indication information, non-3GPP gateway can be initiated the resource release flow of UE at non-3GPP network.This step also can be carried out after step 411 or step 412.

Step 416-step 418, with step 318-step 320 among the embodiment six.

Step 419, when UE after the bearing resource of non-3GPP network is all discharged, non-3GPP gateway sends to separate to PGW and replys (Detach Ack) message informing PGW UE and all discharged in the resource of non-3GPP.

Step 420, HSS/AAA and MME directly carry out the flow process of inserting subscription data (Insert SubscriberData), by this flow process HSS/AAA up-to-date APN and PGW information are sent to MME, and MME can upgrade APN and the PGW information on it.

Step 421, MME are after receiving the APN and PGW lastest imformation that HSS/AAA sends, send and discharge resource (Release Resource) message to UE, carry the indication information that discharges non-3GPP resource (non-3GPPResource Release) in the message, UE receives the bearing resource that discharges after this information in all non-3GPP networks of setting up on UE.

The method of this deletion source resource (is UE switches to limited-service from the source of non-limited-service a target side except applying to above-mentioned scene, optionally, UE is carrying out urgency traffic), this method is equally applicable to UE switches to the target side of non-limited-service from the source of non-limited-service scene, optionally, this UE is in the asset creation failure (comprising all asset creation failures or the failure of a part of asset creation) of target side network, for example one or more PDN connects the foundation failure, perhaps load creating failure, MME is known the asset creation failure (comprising all asset creation failures or the failure of a part of asset creation) of UE.Under this scene, MME sends to PGW and is used to notify the indication information that discharges non-3GPP Internet resources, and PGW initiates resource allocation deexcitation flow process deletion source resource according to described indication information.

The difference of present embodiment and embodiment six is, among the embodiment six, MME sends notice request (Notify Request) message to the HSS/AAA server earlier, notice HSS initiates the Detach flow process (step 314) of non-3GPP network, is sent to non-3GPP gateway by the HSS/AAA server more afterwards and separates Indication message.And in the present embodiment, in step 407 (being the step 307 among the embodiment six), PGW has received default bearer request to create (Create Default Bearer Request) message, carries the limited-service indication information in this message; In step 412 (being the step 312 of embodiment six), PGW has sent the bearer update response to SGW, indicates that PGW has finished the urgency traffic asset creation; Directly send the separation indication information to non-3GPP gateway by PGW then in step 415, non-3GPP gateway is according to separating the resource release flow of indication information initiation at non-3GPP network.By the technical scheme of present embodiment, both guaranteed the normal foundation of urgency traffic, also discharged UE timely at the relevant bearing resource of the non-emergent business of non-3GPP network, thus reduce the bearing resource waste in the non-3GPP network.

The scene of the foregoing description six and embodiment seven is UE switches to the 3GPP network from non-3GPP network handling process.UE switches to non-3GPP network from the 3GPP network can adopt the similar techniques scheme equally, and promptly UE is when non-3GPP network insertion, and PGW has received Binding Update (Proxy Binding Update) message, carries the limited-service indication information in this message; PGW has sent Binding Update to non-3GPP gateway and has upgraded response, indicates that PGW has finished the urgency traffic asset creation; Sent by SGW by PGW then and separate the MME of indication information to the 3GPP network, MME is according to separating the resource release flow of indication information initiation at the 3GPP network.

Embodiment seven

The signaling process figure of the method for processing resource that the network that Fig. 8 provides for the embodiment of the invention seven switches.Scene shown in Figure 8 is: UE switches (optimization handoff procedure) at non-3GPP network (present embodiment is the HRPD network) to the 3GPP net, and there is urgency traffic in UE in non-3GPP network.

As shown in Figure 8, comprise the steps:

Step 501, UE carry out business at the HRPD network, wherein comprise urgency traffic.

Step 502, UE find the 3GPP network coverage, initiate the switching flow to the 3GPP network.

Step 503, UE send Message X (X message) and give HRPD AN, comprise in this message need send to MME adhere to request (Attach Request) message, comprise the urgency traffic indication information in the Attach Request message, the current urgency traffic that exists of sign UE.

Step 504, HRPD AN directly transmit (Direct Transfer) with this Message X and give MME.

Step 505, MME and HSS pass through HRPD AN to the UE authentication, though UE limited-service in the 3GPP network, because there is urgency traffic in UE in the HRPD network, so by authentication to UE.

The flow process of subscription data is upgraded and obtained to executing location between step 506, MME and HSS/AAA, with the MME address registration in HSS, and the subscription data of download UE is connected data with all PDN from HSS, wherein comprises urgency traffic relevant APN and PGW address information.

Step 507, MME send default bearer request to create message to SGW and PGW, and PGW sends specific resource request to create message to PCRF.Owing to the non-emergent business that UE is current is limited, so initiating the relevant PDN of urgency traffic, MME connects foundation, to SGW and the relevant default bearer request to create message of PGW transmission urgency traffic.MME notifies SGW and PGW limited-service indication information in default bearer request to create message simultaneously, informs SGW and PGW, and the UE current service is limited, and except urgency traffic, other professional dedicated bearings are created and/or data forwarding is under an embargo.PGW obtains the PCC rule by send specific resource request to create message to PCRF from PCRF, and initiates the urgent call dedicated bearing and create, and change PGW goes up the RAT of the relevant carrying of urgent call.

Step 508, MME directly transmit message to HRPD AN, comprise in this message of directly transmitting and (adhere to acceptance (Attach Accept) message and carrying and set up request message.Carry UE limited-service indication information in this Attach Accept message, be used to notify UE to delete the relevant bearing resource of non-emergent business.This information also may directly send to UE by MME by independent message or other message.

When if UE switches to the limited-service district of HRPD network from the 3GPP network, HRPD AN need notify UE deletion in 3GPP network of network resource equally, the information that comprises in mode form of message that the mode of concrete notice UE is put down in writing in can this step and the message.

Step 509, HRPD AN send to UE with above-mentioned information by Message X message.

Step 510, UE switch to the 3GPP network, and carry out the flow process of the dedicated bearing establishment of creating radio bearer and urgency traffic.

Step 511, MME send the bearer update request message to SGW.

After step 512, MME finish bearer update, send the bearer update response message to SGW, notice SGW resource is set up and is finished, and can carry out data forwarding.

Step 513, MME send to switch and finish (HO Complete) message to HRPD AN, carry resource (the Detach for non-3GPP) indication information that discharges non-3GPP network in the message.

When if UE switches to the limited-service district of HRPD network from the 3GPP network, HRPD AN can finish in switching equally and notifies MME to initiate the resource release flow of UE at the 3GPP network in (HO Complete) message, and HO Complete message is carried Detach for 3GPP.MME can initiate the flow process at the Detach of 3GPP network, and UE is all discharged in the resource of 3GPP network.

Step 514, HRPD AN initiate the Detach flow process, impel HSGW to initiate resource release flow and delete UE on the PGW in HRPD network of network resource, the PDN that PGW can upgrade in the aaa server connects subscription data, and the PDN that promptly only remaining urgency traffic is relevant connects subscription data.PDN subscription data after AAA will upgrade sends to HSS, and HSS sends and inserts subscription data (Insert Subscriber Data) message informing MME renewal PDN subscription data, the relevant PDN subscription data of deletion non-emergency call.

The method of this deletion source resource (is UE switches to limited-service from the source of non-limited-service a target side except applying to above-mentioned scene, optionally, UE is carrying out urgency traffic), this method is equally applicable to UE switches to the target side of non-limited-service from the source of non-limited-service scene, optionally this UE is in the asset creation failure (comprising all asset creation failures or the failure of a part of asset creation) of target side network, for example one or more PDN connects the foundation failure, perhaps load creating failure, MME is known the asset creation failure (comprising all asset creation failures or the failure of a part of asset creation) of UE.Under this scene, same MME can indicate HRPD AN initiation to discharge non-3GPP Internet resources, and for example attachment removal flow process of described flow process, carrying discharge flow process or PDN connects release flow process etc.

In the present embodiment, UE exists under the situation of urgency traffic in the HRPD network, when UE at the HRPD network in the handoff procedure of 3GPP network, successful establishment the relevant bearer resource of urgency traffic, and after the default bearer establishment dedicated bearing establishment relevant with urgency traffic finished, MME indication HRPD AN initiated bearing resource non-and the HRPD network that urgency traffic is relevant.Thereby reduced because the 3GPP network can't normally created under the bearing resource situation, and the waste of the bearing resource on non-3GPP network that causes.

Embodiment eight

The signaling process figure of the method for processing resource that the network that Fig. 9 provides for the embodiment of the invention eight switches.Scene shown in Figure 9 is: UE switches (optimization handoff procedure) at non-3GPP network (present embodiment is the HRPD network) to the 3GPP net, there is not urgency traffic in UE in non-3GPP network, and in the present embodiment, HRPD AN has got access to the mobility limitation information of UE at the 3GPP network in advance.

As shown in Figure 9, comprise the steps:

Step 601, UE carry out business at the HRPD network, do not comprise urgency traffic.

Step 602, UE find the 3GPP network coverage, initiate the switching flow to the 3GPP network.

Step 603, UE send Message X to HRPD AN, comprise in this message need send to MME adhere to request (Attach Request) message.

Step 604, HRPD AN are according to mobility limitation information and the 3GPP network information of the UE that obtains in advance at the 3GPP network, judge UE limited-service in the 3GPP network, then directly send resource release command (Resource Release Command) message to UE, the bearing resource that indication UE initiates the 3GPP network relevant with this UE discharges flow process.

Step 605, UE initiate resource release flow, discharge the bearing resource of the 3GPP network relevant with this UE.

In the present embodiment, mobility limitation information is stored among the HSS as subscription data, when UE registered in the HRPD network, HSS/AAA (being AAA Proxy under the situation of roaming) can send to HRPD AN as subscription data with the mobility limitation information of UE.When adhering to of HRPD AN receipts UE transmission asks, can judge whether the service of UE in the 3GPP network is restricted like this according to the target side network information of obtaining in mobility limitation information and the handoff procedure (the 3GPP network information).If be restricted, then the resource release command message is given UE, indication UE Internet resources.

In addition, also can directly initiate the bearing resource that resource release flow discharges the relevant HRPD network of UE by HRPD AN.After the resource of network side discharged, HRPD AN carried all related resources on the limited-service indication information notice UE deletion UE by independent newly-increased message or existing message.

The handoff process that above-mentioned steps in the present embodiment is UE when the HRPD network switches to the 3GPP network, when if UE switches to the HRPD network from the 3GPP network, MME can just judge that UE is in HRPD network limited-service according to the mobility limitation information of obtaining from HSS before carrying out switching, MME also can directly send the resource release command message to UE like this, carry the limited-service indication information in the message, indication UE initiates the Detach flow process and discharges the Internet resources of UE in the 3GPP network; Perhaps directly initiate the bearing resource that the Detach flow process discharges the 3GPP network by MME, afterwards, MME is by carrying the resource on the limited-service indication information notice UE deletion UE in independent newly-increased message or the existing message.

In the present embodiment, HRPD AN has just obtained the target side network information that UE obtains in restricted information of the mobility of 3GPP network side and handoff procedure before switching, in handoff procedure, HRPDAN just can directly judge the restricted situation of UE in the 3GPP network, and directly initiate resource release flow, and do not need the entity of 3GPP network to indicate.In this way, also reduced because the 3GPP network can't normally created under the bearing resource situation, and the waste of the bearing resource on non-3GPP network that causes.

Embodiment nine

The signaling process figure of the method for processing resource that the network that Figure 10 provides for the embodiment of the invention nine switches.Scene shown in Figure 10 is: UE switches to non-3GPP net at the 3GPP network, and there is urgency traffic in UE in non-3GPP network.

As shown in figure 10, comprise the steps:

Step 701, UE carry out business at the 3GPP network, wherein comprise urgency traffic.

Step 702, UE find the non-3GPP network coverage, are initiated to the switching of non-3GPP network.

Step 703, UE and non-3GPP gateway and HSS/AAA carry out authentication and authentication, and non-3GPP gateway obtains APN and PGW address in this process from HSS/AAA.Under the roaming scence, non-3GPP gateway obtains APN by AAA Proxy from the aaa server of ownership place and PGW is right.Because wherein comprise urgency traffic relevant APN and PGW, thus though non-3GPP gateway judges that the UE current service is limited, owing to have urgency traffic, so authentication and authentication are passed through.Wherein non-3GPP gateway can right and wrong 3GPP IP IAD or other gateways such as ePDG or MAG.

Step 704, UE send to non-3GPP gateway and adhere to triggering (Attach Trigger) message.

Step 705, non-3GPP gateway connect at the relevant PDN of urgent call, send Binding Update (Proxy Binding Update) message and give PGW, carry UE sign APN relevant and PGW information and access technology type (Access Technology Type is called for short ATT) value and Lifetime in the message with urgency traffic.Lifetime sign PMIP tunnel time-to-live section.It has been the access connection of non-3GPP network that this PDN of ATT value representation connects.Except above-mentioned information is also carried a limited-service indication information, indication PGW must not transmit non-emergent business datum.

After UE left the limited-service zone, non-3GPP gateway will send Binding Update (ProxyBinding Update) message or other message is given PGW, carries the normal service indication information in the message, and indication PGW can transmit non-emergent business datum.

Step 706, PGW send Binding Update and reply (Proxy Binding Ack) message to non-3GPP gateway.

Step 707, non-3GPP gateway send to adhere to finishes (Attach Completion) message to UE.

This message also can be carried limited-service indication information or other indication informations, and UE deletes non-emergent service resources with indication.This information also can send by independent message.If sent to UE in this step and carried the limited-service indication information, following step 712 can be omitted.In addition, step 707 and step 708 do not have sequential relationship successively.

Step 708, non-3GPP gateway send and separate Indication message to PGW, (PGW sends to AAA earlier PGW to HSS/AAA, AAA will separate indication information again and send to HSS) send and separate Indication message, carry resource (the Detach for 3GPP) indication information that discharges the 3GPP network in the message.The attachment removal flow process release UE that aaa server indication HSS initiates at the 3GPP network sends the separation Indication message to AAA and HSS at the bearing resource or the non-3GPP gateway of source network, carries resource (the Detach for 3GPP) indication information that discharges the 3GPP network in the message.

Step 709, HSS/AAA server send to MME and separate Indication message.

Step 710, MME initiate the Detach flow process.MME discharges all resources at the 3GPP network.The PDN that urgency traffic is relevant is connected non-3GPP network of network resource and can be released, because ATT has not been EUTRAN.After resource discharged and finishes, MME indication HSS upgraded APN and the PGW information relevant with this UE.

Carry out between step 711, HSS/AAA and the PGW and insert the subscription data flow process.After the PDN subscription data changes among the HSS, can upgrade the subscription data among the AAA, AAA will arrive PGW with information updating again, and PGW arrives non-3GPP gateway with this information updating; Perhaps HSS/AAA directly arrives non-3GPP gateway with this information updating.

Step 712, non-3GPP gateway send resource deletion indication (Resource DeleteIndication) message to UE, carry limited-service indication information or other indication informations in the message, inform all bearing resources that the UE deletion is set up on UE at the 3GPP network.

The method of this deletion source resource (is UE switches to limited-service from the source of non-limited-service a target side except applying to above-mentioned scene, optionally, UE is carrying out urgency traffic), this method is equally applicable to UE switches to the target side of non-limited-service from the source of non-limited-service scene, optionally, this UE is in the asset creation failure (comprising all asset creation failures or the failure of a part of asset creation) of target side network, for example one or more PDN connects the foundation failure, perhaps load creating failure, MME is known the asset creation failure (comprising all asset creation failures or the failure of a part of asset creation) of UE.Under this scene, same non-3GPP gateway is used to notify the indication information that discharges the 3GPP Internet resources except sending to MME by HSS and/or AAA.Perhaps non-3GPP gateway can be used to notify the indication information that discharges the 3GPP Internet resources to the MME transmission to PGW and/or HSS/AAA, MME initiates resource allocation deexcitation flow process deletion source resource according to described indication information, and for example attachment removal flow process of described flow process, carrying discharge flow process or the PDN connection discharges flow process etc.
