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

In the current wireless architectures of communication networks, there are simultaneously 3GPP (third generation partner program) network and non-3GPP network, UE need to switch between 3GPP network and non-3GPP network.Before switching was completed, the network of carrying UE business was called the source network; After switching was completed, the network of carrying user terminal (User Equipment is called for short UE) business was called the target side network.Switch to example from 3GPP network (source network) to non-3GPP network (target side network) with UE, after carrying out switching, guarantee the business continuity of UE.Detailed process is as follows: UE successfully adheres at the target side network, the bearing resource of target side network creation to this UE, and with grouped data network gateway (the PacketData Network Gateway of UE at the source network, 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 to complete switching by UE in the success of target side network, but source network in 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 suitable residential quarter and is stationed) when target side is network limited, 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 releasing 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 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 (be UE at target side network successfully create a part of resource at the Internet resources of target side all not creating successfully because the reasons such as resource shortage or capacity of equipment restriction cause UE, perhaps UE all creates failure in the resource of target side network), this moment, PGW can't normally discharge UE in the resource of source network.Therefore, UE can't be released at the source network.Thereby caused the waste of source Internet resources.

Step 10, in user terminal access target side network development process, the objective network side knows that described user terminal in limited-service or the asset creation failure of described target side network, sends the first indication information to source network or grouped data network gateway.Described the first indication information carries the indication information of the resource of the source network that discharges described user terminal.the first indication information is the indication information of the source Internet resources of releasing user terminal, this first indication information can be to separate indication (Detach indication) message, discharge the information of carrying in resource (the Detach for non-3GPP) Indication message of non-3GPP network, can be also the indication user terminal information of carrying in the indication information that the target side network is restricted or asset creation failure reason value etc., those skilled in the art are to be understood that, information is in the process of transmitting, its concrete carrying form is with different, concrete information carrying form, the present embodiment does not limit.

The target side network is after the asset creation failure of finding the limited or target side Network finding user terminal of subscriber terminal service, can initiatively initiate the release of source Internet resources by the mode that sends Indication message, limited or user terminal creates unsuccessfully at the target side Internet resources in the situation that user terminal is at the target side network service thereby played, the control that the source Internet resources are discharged.

After the target side network sent the first indication information, source network or grouped data network gateway can be carried out following operation:

The first indication information that step 11, source network or grouped data network gateway receiving target side network send.

The resource of the source network of step 12, releasing user terminal.This step can be specially:

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

Upgrade the information relevant to user terminal in HSS and AAA, these information spinners will refer to 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 user terminal is mainly 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 the first Indication message can be the 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 the first Indication message can also be 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 user terminal in the limited-service of 3GPP network in the access 3GPP of user terminal network development process, sends the first indication information by HSS and AAA to non-3GPP gateway.Perhaps MME directly to PGW sends first indication information through gateway SGW to PGW transmission the first indication information or MME to grouped data network gateway (PGW) transmission the first indication information or MME through HSS and/or AAA.

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

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

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

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

In addition, can further include in 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 PGW, SGW is with regard to the data retransmission of asset creation and the non-emergent business of no longer carrying out non-emergent business; When adopting the GTP agreement between SGW and PGW, PGW is with regard to the data retransmission of asset creation and the non-emergent business of no longer carrying out 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 is known user terminal in limited-service or the asset creation failure of non-3GPP network, and is had urgency traffic at the source network in the non-3GPP network development process of user terminal access;

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

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

In addition, can further include in 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 asset creation and the data retransmission 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 the 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 is known user terminal in limited-service or the asset creation failure of non-3GPP network, and is had urgency traffic at the source network in the non-3GPP network development process of user terminal access;

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

HRPD AN sends the first indication information to MME.

In the present embodiment, in the handoff procedure of 3GPP network and non-3GPP network, as UE when the target side network adheres to, if the entity of target side network is found the limited-service for this UE, generate first indication information, and send to 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 prior art, due to the target side network in 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 present 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 at UE when the source network carries out the position registration, send to mobility limitation information the entity of source network by HSS and AAA as subscription data.Mobility limitation information specifically refers to user terminal limited-service in which zone.In addition, need to prove, in an embodiment of the present invention, HSS can separate setting with AAA, also can be wholely set to be HSS/AAA.Wherein, AAA has comprised 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 knows that user terminal is in the limited-service of target side network.Wherein, the relevant information of target side network can in the process of carrying out the network switching, be obtained by Attach Request message.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 specific lane place, and perhaps user terminal limited-service etc. 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 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, the target side network information is location area information; If mobility limitation information is Access Network side information, the target side network identity is the 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, releasing 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 the 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 to user terminal of source network; Upgrade the information relevant to user terminal in HSS and AAA; The resource information of the source network in the deletion user terminal.

The present embodiment preferably is applied in to be optimized in the scene of switching, and according to optimizing in 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 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: after HRPD AN received the Attach Request message that user terminal adheres to the 3GPP network, HRPD AN knew that according to mobility limitation information user terminal is in the limited-service of target side network.

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 mobile terminal from HSS;

Step 21 can be specially: after MME received the Attach Request message that user terminal adheres to the CDMA2000 network, MME knew that according to mobility limitation information user terminal is in the limited-service of target side network.

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.When the entity of source network has known that network switches generation, according to these mobility limitation information, whether just can directly judge UE in the limited situation of objective network side presence service like this.If the result of judgement is the limited-service in the objective network side, just can play in the sending and receiving of source direct network the flow process of releasing bearing resource.Reduced like this in prior art, because the target side network can't normally create in 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 present 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, then initiate to switch to from non-3GPP network the switching flow of 3GPP network.This switching flow is initiated to switch by UE and is adhered to (Handover Attach) flow process and realize.

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, HSS/AAA.In this process, MME judgement UE is 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 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 MME can Direct Recognition to go out the business relevant to 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 notice HSS to be initiated 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 (Detach indication) message except increase resource (Detach for non-3GPP) indication information that discharges non-3GPP network in this message.

After step 106, HSS receive resource (Detach fornon-3GPP) indication information of the non-3GPP network of release that MME sends, then send and separate indication (Detach indication) message to 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 figure).The non-3GPP gateway here can be the non-3GPP IP IAD of MAG, ePDG, ASN GW etc.Above-mentioned separation (Detach) flow process is adopting S2a (interface between non-3GPP IP IAD and PGW) and S2b (interface between ePDG and PGW) scene all to be suitable for.

If adopting under S2c (interface between UE and PGW) scene, the aaa server of ownership place (non-roaming scene) or AAA Proxy (roaming scence) send Session Termination (session termination) message to PGW, the PDN that notice PGW deletion is relevant to this UE connects, situation in not shown being somebody's turn to do in 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 message, be called for short APN) and user ID, this message is used to indicate PGW and deletes the relevant PDN connection of this UE.

After step 108, PGW receive above-mentioned Proxy Binding Update message, not deleting immediately the relevant PDN of this UE that sets up on PGW connects, but send Update PDN GW Address (upgrade PGW address) message to the AAA Server of ownership place or sent to the AAA Server (under roaming scence) of ownership place by AAA Proxy, APN and PGW information in connecting with the AAA Server deletion of the indication ownership place PDN relevant to 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 to this UE of recording in HSS is deleted, namely completed the registration process of UE in HSS.After deletion was completed, HSS/AAA notified PGW.

Step 109, PGW deletion and the carrying Session Resources that this PDN join dependency joins send binding and reply (Proxy Binding Ack) message to non-3GPP gateway, carry Lifetime=0 and user ID, and sign PDG has completed the deletion of PDN connection.

Step 110, non-3GPP gateway are deleted the bearing resource of this UE in non-3GPP network, then send 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, then send message informing response (Notify Response) or separate and reply this UE of (Detach Ack) message informing MME and complete 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 to 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 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 that UE switches to the target side of limited-service from the source of non-limited-service except applying to above-mentioned scene, optionally, UE is carrying out urgency traffic), the method is equally applicable to UE and switches to the scene of the target side of non-limited-service from the source of non-limited-service, 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 connection is set up unsuccessfully, 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 for the indication information that notice discharges non-3GPP Internet resources, non-3GPP gateway is initiated deletion source resource flow process according to described indication information, and described flow process such as attachment removal flow process, carrying discharge flow process or PDN Connection Release flow process etc.

In the present embodiment, UE is not in the situation that exist urgency traffic in non-3GPP network, when UE at non-3GPP network in the handoff procedure of 3GPP network, although UE adheres to unsuccessfully in the 3GPP network, but, by the MME in the 3GPP network the judgement UE limited-service after, 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 create in 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 present 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.Obtain APN and PGW address in this process from HSS/AAA.Under roaming scence, the aaa server of AAA Proxy by ownership place obtains APN and PGW pair from HSS.Non-3GPP gateway judgement UE current service is limited, and there is no urgency traffic, so authentication and authentication are not passed through.Wherein non-3GPP gateway can be non-3GPPIP IAD or the 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, first send to AAA Proxy, 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, deleting Internet resources or the non-3GPP gateway of UE in the 3GPP network with this directly sends to AAA and HSS and separates Indication message, carry resource (the Detach for 3GPP) indication information that discharges the 3GPP network in this message.

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

Step 206, MME initiate deletion UE at the bearing resource of 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 to 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 UE deletion UE in this message.

the method of this deletion source resource (is that UE switches to the target side of limited-service from the source of non-limited-service except applying to above-mentioned scene, optionally, UE is carrying out urgency traffic), the method is equally applicable to UE and switches to the scene of the target side of non-limited-service from the source of non-limited-service, 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 connection is set up unsuccessfully, perhaps load creating failure, non-3GPP gateway 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 for except sending to MME by HSS and/or AAA the indication information that notice discharges the 3GPP Internet resources.Perhaps non-3GPP gateway can to PGW and/or, HSS and/or AAA send to MME and be used for the indication information that notice discharges the 3GPP Internet resources, MME is according to described indication information start flow deletion source resource, and described flow process such as attachment removal flow process, carrying discharge flow process or PDN Connection Release flow process etc.。

In the present embodiment, UE is not in the situation that exist urgency traffic in the 3GPP network, when UE at the 3GPP network in the handoff procedure of non-3GPP network, although UE adheres to unsuccessfully in non-3GPP network, but, by the non-3GPP gateway in non-3GPP network the judgement UE limited-service after, 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 create in 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 present 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 initiate to switch to from non-3GPP the switching flow of 3GPP then according to the 3GPP network insertion being detected, and this switching flow is initiated switching by UE and adhered to (Handover Attach) flow process and realize.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 the information such as Attach Type and urgent call indication information in 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, HSS.There is urgency traffic because UE is current, so although UE is current limited at the 3GPP network service, the 3GPP network still allows the UE access.

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 confirmation (Update Location Ack) message to MME, carry IMSI and CAMEL-Subscription-Information (Subscription data) in 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 is transmitted to the relevant PGW of this urgency traffic with this message, this step is used for being connected according to the relevant APN of urgency traffic the default bearer resource that PDN connects with the PGW information creating, and by this UE limited-service of this process notice PGW.Carry the relevant APN of urgent call and PGW information, wireless access type (Radio Access Type in this message, abbreviation RAT), the information such as indication message, limited-service indication information, SGW address and Tunnel Identifier (Tunneling ID is called for short TEID).Wherein, RAT type (RATType) information is used to indicate current this PDN and is connected in the 3GPP network.Switch indication (HandoverIndication) information and be used for representing the current switching flow that switches to 3GPP for non-3GPP.APN represents the APN relevant to urgent call and PGW information with PGW information.SGW address and TEID represent that SGW is that PGW is data downstream address and the Tunnel Identifier of this load creating.

Situation shown in figure is to be the situation of GTP (GPRS Tunnel Protocol) agreement between SGW and PGW, and SGW forwards 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 retransmission.In addition, if between SGW and PGW be the situation (not shown) of PMIP (proxy-mobile IP) agreement, 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 retransmission.The present embodiment is to illustrate as the GTP agreement between SGW and PGW.

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

Step 308, PGW are current according to the indication message judgement is switching flow, then obtains PCC (strategy and charging) rule to PCRF, and the PCC rule downloading that PCRF is correlated with this UE is to PGW.This step is optional, and PGW also can utilize the rule that self configures to initiate following load creating.

The dedicated bearing that step 309, PGW initiate default bearer and urgent call according to the PCC rule of obtaining from PCRF creates, and obtained the limited-service indication information due to PGW, thereby the resource bearing that makes PGW can not initiate other business creates in step 307.This process has created the carrying between UE and eNodeB and SGW and 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 message.

Step 311, SGW send the bearer update request message to PGW according to the indication message in step 310, carry indication message in 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, due to UE limited-service in the 3GPP network, therefore, MME sends notice request (Notify Request) message to HSS/AAA, carry resource (the Detach for non-3GPP) indication information that discharges non-3GPP network in message, indication HSS initiates the Detach flow process of non-3GPP network, thereby discharges UE at the bearing resource of 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 at non-3GPP network of setting up in deletion UE.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.

step 317, after HSS receives resource (Detach fornon-3GPP) indication information of the non-3GPP network of release that MME sends, then 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 figure), 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 PGW) and S2b (interface between ePDG and PGW) scene.Under S2c (interface between UE and 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 sets up in non-3GPP network of network resource on PGW.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 entirely deleted 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 to PGW, carry Lifetime (life cycle)=0 and APN and user ID in message, this message indication PGW deletes the relevant PDN of this UE and connects.

Step 319, PGW send to be upgraded PGW address (Update PDN GW Address) message to the aaa server of ownership place or is transferred to the aaa server of ownership place by AAA Proxy, the aaa server deletion of indication ownership place and APN and the PGW information of above-mentioned PDN join dependency, the aaa server notice HSS of ownership place carries out Data Update.All so non-emergent relevant PDN connect deleted after, the APN that in HSS, only remaining urgency traffic is relevant and PGW pair.

Step 320, PGW delete all with the carrying session of 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 message, this message identifier PGW has deleted relevant PDN and has connected.Non-3GPP gateway is received the bearing resource of deleting again all non-emergent business of setting up after this message in non-3GPP network.

Step 321, HSS are crossed insertion subscription data (InsertSubscriber Data) flow process with up-to-date APN and PGW information exchange and are updated to MME, and MME deletes the PDN link information of all non-emergent traffic aideds.

Be with above-described embodiment four and embodiment five differences, because there has been urgency traffic in UE at non-3GPP network, after switching, although non-emergent business is restricted, but the 3GPP network still will create 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 transmission is indicated simultaneously.So both guaranteed the normal foundation of urgency traffic, also discharged timely the bearing resource of UE at the non-emergent traffic aided of non-3GPP network, thus reduce the bearing resource waste in 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 present 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 the present embodiment is identical with step 301-step 313 in embodiment five, does not repeat them here.

Step 414, after the urgency traffic asset creation is completed, 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 step 407 (being the step 307 in 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 message, by this indication information, non-3GPP gateway can be initiated UE in the resource release flow of 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 in embodiment six.

Step 419, as UE after the bearing resource of non-3GPP network is all discharged, non-3GPP gateway send to separate to PGW replys (Detach Ack) message informing PGW UE and is 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 releasing resource (Release Resource) message to UE, carry the indication information that discharges non-3GPP resource (non-3GPPResource Release) in 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 that UE switches to the target side of limited-service from the source of non-limited-service except applying to above-mentioned scene, optionally, UE is carrying out urgency traffic), the method is equally applicable to UE and switches to the scene of the target side of non-limited-service from the source of non-limited-service, 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 connection is set up unsuccessfully, 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 for the indication information that notice discharges non-3GPP Internet resources, and PGW initiates resource according to described indication information and distributes deexcitation flow process deletion source resource.

The difference of the present embodiment and embodiment six is, in embodiment six, MME first sends notice request (Notify Request) message to the HSS/AAA server, 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 in 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 completed the urgency traffic asset creation; Then directly sent by PGW in step 415 and separate indication information to non-3GPP gateway, non-3GPP gateway is according to separating the resource release flow of indication information initiation at non-3GPP network.By the technical scheme of the present embodiment, both guaranteed the normal foundation of urgency traffic, also discharged timely the bearing resource of UE at the non-emergent traffic aided of non-3GPP network, thus reduce the bearing resource waste in non-3GPP network.

The scene of above-described embodiment six and embodiment seven is UE and switches to the handling process of 3GPP network from non-3GPP network.UE switches to non-3GPP network from the 3GPP network can adopt similar technical scheme equally, and namely 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 completed the urgency traffic asset creation; Then sent by SGW by PGW and separate indication information to the MME of 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 present invention seven switches.Scene shown in Figure 8 is: UE switches (optimization handoff procedure) at non-3GPP network (the 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) to HRPD AN, comprise in this message and need to send to that MME's adhere to request (Attach Request) message, comprise the urgency traffic indication information in Attach Request message, the current urgency traffic that exists of sign UE.

Step 504, HRPD AN directly forward (Direct Transfer) to MME with this Message X.

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

Between step 506, MME and HSS/AAA, the flow process of subscription data is upgraded and obtained to executing location, with the MME address registration in HSS, and download subscription data and all PDN connection data of UE from HSS, wherein comprise 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.Because the non-emergent business that UE is current is limited, so initiating the relevant PDN of urgency traffic, MME connects foundation, send the relevant default bearer request to create message of urgency traffic to SGW and PGW.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, the dedicated bearing of other business creates and/or data retransmission is under an embargo.PGW obtains the PCC rule by send specific resource request to create message to PCRF from PCRF, and initiates the establishment of urgent call dedicated bearing, the RAT of the carrying that the upper urgent call of change PGW is relevant.

Step 508, MME are to the direct forwarding messages of HRPD AN, and this message that directly forwards comprises (adheres 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 for the bearing resource of the non-emergent traffic aided of notice UE deletion.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 to notify UE deletion in 3GPP network of network resource equally, the information that comprises in the mode form of message that the mode of concrete notice UE is put down in writing in can this step and message.

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

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

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

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

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

When if UE switches to the limited-service district of HRPD network from the 3GPP network, HRPD AN can complete in switching equally and notify MME to initiate UE in the resource release flow of 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 PGW in HRPD network of network resource, the PDN that PGW can upgrade in aaa server connects subscription data, and the PDN that namely 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 that UE switches to the target side of limited-service from the source of non-limited-service except applying to above-mentioned scene, optionally, UE is carrying out urgency traffic), the method is equally applicable to UE and switches to the scene of the target side of non-limited-service from the source of non-limited-service, optional 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 connection is set up unsuccessfully, 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 to initiate to discharge non-3GPP Internet resources, and described flow process such as attachment removal flow process, carrying discharge flow process or PDN Connection Release flow process etc.

In the present embodiment, UE is in the situation that exist 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 completed, 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 create in 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 present invention eight switches.Scene shown in Figure 9 is: UE switches (optimization handoff procedure) at non-3GPP network (the 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 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 to send to that MME's 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, judgement UE limited-service in the 3GPP network, directly send resource release command (Resource Release Command) message to UE, the bearing resource that indication UE initiates the 3GPP network relevant to this UE discharges flow process.

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

In the present embodiment, mobility limitation information is stored in HSS as subscription data, when UE registered in the HRPD network, HSS/AAA (being AAA Proxy in 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 according to the target side network information of obtaining in mobility limitation information and handoff procedure (the 3GPP network information) like this.If be restricted, the resource release command message to UE, is indicated the 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 limited-service indication information notice UE deletion UE by independent newly-increased message or existing message.

Above-mentioned steps in the present embodiment is the handoff process of UE when switching to the 3GPP network from the HRPD network, when if UE switches to the HRPD network from the 3GPP network, MME can just judge that UE is limited at the HRPD network 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 message, indication UE initiates the Detach flow process and discharges the Internet resources of UE in the 3GPP network; Perhaps directly initiate by MME the bearing resource that the Detach flow process discharges the 3GPP network, afterwards, MME is by carrying the resource on limited-service indication information notice UE deletion UE in independent newly-increased message or existing message.

In the present embodiment, HRPD AN has just obtained the target side network information that UE obtains in the mobility limitation information 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 create in 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 present 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 in this process, non-3GPP gateway obtains APN and PGW address from HSS/AAA.Under roaming scence, non-3GPP gateway obtains APN and PGW pair from the aaa server of ownership place by AAA Proxy.Owing to wherein comprising urgency traffic relevant APN and PGW, so although non-3GPP gateway judgement UE current service is limited, owing to there being urgency traffic, so authentication and authentication are passed through.Wherein non-3GPP gateway can be non-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 for the relevant PDN of urgent call, send Binding Update (Proxy Binding Update) message to PGW, carry the UE sign APN relevant with urgency traffic and PGW information and access technology type (Access Technology Type is called for short ATT) value and Lifetime in message.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 forward non-emergent business datum.

After UE left the limited-service zone, non-3GPP gateway will send Binding Update (ProxyBinding Update) message or other message to PGW, carries the normal service indication information in message, and indication PGW can forward 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 completes (Attach Completion) message to UE.

This message also can be carried limited-service indication information or other indication informations, with the non-emergent service resources of indication UE deletion.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 are without the priority sequential relationship.

Step 708, non-3GPP gateway send and separate Indication message to PGW, (PGW first sends to AAA 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 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 bearing resource or the non-3GPP gateway of source network, carries resource (the Detach for 3GPP) indication information that discharges the 3GPP network in 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 to non-3GPP network of network resource and can be released, because ATT has not been EUTRAN.After resource discharged and completes, MME indication HSS upgraded APN and the PGW information relevant to this UE.

Carry out between step 711, HSS/AAA and PGW and insert the subscription data flow process.After in HSS, the PDN subscription data changes, can upgrade the subscription data in 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 message, inform all bearing resources at the 3GPP network that the UE deletion is set up on UE.

the method of this deletion source resource (is that UE switches to the target side of limited-service from the source of non-limited-service except applying to above-mentioned scene, optionally, UE is carrying out urgency traffic), the method is equally applicable to UE and switches to the scene of the target side of non-limited-service from the source of non-limited-service, 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 connection is set up unsuccessfully, 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 for except sending to MME by HSS and/or AAA the indication information that notice discharges the 3GPP Internet resources.Perhaps non-3GPP gateway can send the indication information that is used for notice release 3GPP Internet resources to PGW and/or HSS/AAA to MME, MME initiates resource according to described indication information and distributes deexcitation flow process deletion source resource, and described flow process such as attachment removal flow process, carrying discharge flow process or PDN Connection Release flow process etc.
