B21-B23 is identical with B11-B13.

B24, PDN GW start timer when receiving the deleting load-bearing request message, wait for that UE initiates the resource switch request message in non-3GPP network.

If before the B25-B26 timer expiry, do not receive the resource switch request (described resource switch request is used for asking the business with current network to switch in the objective network) of UE, the business information of the UE that PDN GW deletion is preserved, and in current network, be released to the resource that UE distributes, send IP CAN session modification request message to PCRF, notice PCRF deletes PCC rule corresponding to this resource; If before the timer expiry, PDN GW receives the resource switch request of UE, PDN GW sends IP CAN session modification request message to PCRF, can in this message, report access style to change event, PCRF generates the relevant PCC rule of IP CAN session, send IP CAN session modification response message to PDN GW, carry this PCC rule in this IP CAN session modification response message, the PCC rule that PDN GW is relevant according to this IP CAN session, for UE reserves resource in objective network, business is switched in the objective network;

Perhaps, if the PCC of configuring static rule before the timer expiry, does not receive the resource switch request of UE on the PDN GW, the business information of the UE that PDN GW deletion is preserved, and in current network, be released to the resource that UE distributes; If before the timer expiry, receive the resource switch request of UE, then keep the business information of UE, according to the resource switch request of UE, definite objective network that should switch, and generate the PCC rule, in objective network, reserve resource according to this PCC rule for UE, business is switched in the objective network.

B27, PDN GW send the deleting bearing response message to S-GW, and S-GW sends the deleting bearing response message to mobile management network element.

B28, UE send to separate to mobile management network element and accept message.If UE is the access of multiple access pattern, UE can be chosen in other networks and initiate resource foundation request, for d/d business is set up resource.

When network side is initiated separation process in the embodiment of the invention three, mobile management network element is issued PDN GW with the reason indication, when if this reason indication expression need to discharge the bearing resource of UE in current network owing to the network side reason, PDN GW starts timer, if before timer expiry, receive the resource switch request that UE sends, then do not delete the business information of UE, and in other networks, set up resource for this UE, in order to the business in the current network is switched in other networks, to guarantee professional continuity.

The invention described above embodiment two, embodiment three has described owing to the network side reason need to discharge the bearing resource of UE in the 3GPP network, if owing to the network side reason need to discharge the bearing resource of UE in non-3GPP network, when aaa server/HSS initiates separation process, IAD sends registration to PDN GW and recalls message or agent binding update messages, carry indication need to discharge the bearing resource of UE in non-3GPP network owing to the network side reason indication information in this message, associated description among the processing mode of PDN GW and above-described embodiment two and the embodiment three is corresponding, does not repeat them here.

Need to prove: above-described embodiment two and embodiment three are not limited in the separation process that core-network side is initiated.Carry out in the process in the UE business, if access network element/gateway is owing to the reason of the network sides such as inadequate resource, initiate carrying and discharge flow process, cause the business of UE can not carry out in current network, PDNGW also can switch business alternately with PCRF, perhaps PDN GW has configured static PCC rule, directly data flow is switched to objective network.

In addition: UE is in the process that switches, if the professional network side access network element that should switch to/these class network side reasons such as gateway inadequate resource, initiate carrying and discharge flow process, cause the business of UE can not carry out at this network, PDN GW also can switch business alternately with PCRF, perhaps PDN GW has configured static PCC rule, directly data flow is switched to other networks.

Therefore, the present embodiment and subsequent embodiment four, five are applicable to the resource that the reason owing to network side causes distributing to the user and are released, wherein, the network side reason comprises: aaa server/HSS initiates separation process, access network element/gateway inadequate resource or network side and UE is carried out the reasons such as access control, PDN GW can notify PCRF, determined whether business to be switched to the network of other networks and switching by PCRF, PDN GW also can own decision.

Consult Fig. 4, the embodiment of the invention four provides a kind of business switch method, and the Access Network side in the method in the 3GPP network is initiated switching flow or deleting load-bearing flow process, comprises the steps:

C11, access network element initiate switching flow or evolution base station eNodeB initiates the deleting load-bearing flow process.

This step is applicable to carrying out in the process in the business of UE, and the Access Network side is because inadequate resource, and the part carrying that discharges UE causes some business of UE to be interrupted, and its access network element initiates switching flow or eNodeB initiates the deleting load-bearing flow process.

Perhaps, UE is in the process that switches, if the professional network side access network element that should switch to/gateway inadequate resource needs to discharge the part carrying of UE, access network element initiates switching flow or eNodeB initiates the deleting load-bearing flow process.

C12, mobile management network element send the deleting bearing request message by S-GW to PDN GW, carry indication information in this message, this indication information indication is owing to the network side reason need to discharge the bearing resource of UE in current network, and this indication information can be the Cause cause value.

C13-C14, PDN GW judge that this UE whether with the access of multimodality pattern, if not, then deletes the business information of UE, discharge the bearing resource of UE, process ends; If so, send IP CAN session modification request message to PCRF, can carry the indication information that the indication current network can not provide for UE service in this message.After PCRF receives IP CAN session modification message, according in the information such as the subscription data of the situation of described current network, UE and carrier policy at least one, generate the relevant PCC rule of IP CAN session, send IP CAN session modification response message to PDN GW, carry above-mentioned PCC rule in this message, PCRF recommends and the business of carrying out in the current network can be switched in the objective network in this step, namely in objective network, can proceed this business, in IP CAN session modification response message, can also carry the access style of this objective network.

Perhaps, PDN GW is according at least one and the business information of UE in the information such as resource situation of carrier policy and other networks, determine and the business in the current network need to be switched to objective network, send IP CAN session modification message to PCRF, with the relevant PCC rule of request IP CAN session, PCRF generates the relevant PCC rule of IP CAN session and sends to PDN GW, then carries out C15.

Perhaps, the PCC of configuring static rule on the PDN GW, by PDN GW according at least one and the business information of UE in the information such as resource situation of carrier policy and other networks, determine and the business in the current network need to be switched to objective network, and it is regular to generate PCC, be the professional resource of in objective network, reserving according to this PCC rule, after business switched to objective network, resource in the current network is discharged, and the PDN GW that then continues to carry out among the follow-up C15 sends the deleting bearing response message to S-GW.

The PCC rule that C15, PDN GW are relevant according to IP CAN session for UE distributes new bearing resource, sends the deleting bearing response message to S-GW in objective network, S-GW sends the deleting bearing response message to mobile management network element.

Can carry indication information " Resource Allocated " in the above-mentioned deleting bearing response message, reserved bearing resource at other networks as UE take indication, can also carry the access style of reserving the objective network of bearing resource into UE in this deleting bearing response message, perhaps carry both combinations in the response message.

C16, mobile management network element send the deleting load-bearing request to UE, carry " Resource Allocated " in this deleting load-bearing request or are the access style of the objective network of UE reservation bearing resource, the perhaps combination of the two.

C17, UE send deleting load-bearing to mobile management network element and confirm.If do not carry the access style of reserving the objective network of bearing resource into UE in the deleting load-bearing request, and UE is with the access of multiple access pattern, and UE can initiate resource at other networks and set up request, for business is set up resource.

If in above-mentioned network for UE reservation bearing resource, have BBERF (if right and wrong 3GPP network, IAD can be BBERF), then PCRF sends the relevant PCC rule of gateway control session to BBERF, and BBERF carries out this PCC rule, initiates the resource Establishing process.

When access network element is initiated switching flow or eNodeB initiation deleting load-bearing flow process in the embodiment of the invention four, mobile management network element is issued PDN GW with the reason indication, if this reason indication expression is owing to the network side reason, when need discharging the bearing resource of UE in current network, after PDN GW judges that obtaining UE accesses with the multiple access pattern, do not delete the business information of UE, and in other networks, set up resource for this UE, in order to the business of transmitting in the current network is switched in other networks, to guarantee professional continuity.
