Description
Technical field
The present invention relates to fields of communication technology, the in particular to a kind of processing method of PDU session flow unloading branch
And device.
Background technique
3GPP 5G core net is to support flow unloading, in a protocol Data Unit session (Protocol Data
Unit, i.e. PDU session) in specify multiple PDU session anchor points.Wherein SSC (session and service
Continuity) mode 1 is applied only on the PDU session anchor point (i.e. macro anchor point) of centralized services.
In the prior art, to realize flow unloading in a network, additional point of PDU session distribution is proposed
The settling mode of branch specifically defines Uplink classifier UL CL mode (i.e. Uplink classifier) He Duojia
Township's protocol Data Unit conversational mode (i.e. multi-homed PDU session mode).
Wherein, for the mode of UL Classifier, network determines to insert in the data path of a PDU session
Enter a Uplink classifier.The function of Uplink classifier is according to conversation management functional (Session
Management Function, i.e. SMF) provide traffic filter (traffic filtering) information, corresponding Business Stream is unloaded
It is downloaded to the anchor point of local service.
For Multi-homed PDU Session mode, before a PDU session is associated with more than one IPv6
Sew, provides and data network is linked by more than one PDU session anchor point.Branch point (Branching Point) is not
With the branch point in user plane data path, Branching Point provides forwarding uplink data and flows to different IP anchor points, and
The downlink data for merging different IPv6 anchor points flows to user equipment (User Equipment, i.e. UE).SMF can determine insertion and
Delete UPF (the User Plane that Branching Point function is supported on the data path of a PDU session
Function, user-plane function), wherein different IPv6 prefixes identify different UPF.
The either mode of UL Classifier or the mode of multi-homed PDU session, since flow unloads
Carrying corresponding anchor point is a local service anchor point, there is its service range.When UE occurs mobile, the change of the position of UE can
Network can be brought to reselect a new PDU session anchor point.Such as the local PDU of Multi-homed PDU session
The reselection procedure process of session anchor point (SSC mode 3) is as shown in Figure 1, wherein PSA1 indicates the PDU of a local
Session anchor point, PSA2 indicate the new PDU session anchor point after gravity treatment, and specific process flow is as follows:
S1:UE has determined that a local PDU session anchor point 1 (except the macro anchor point of SSC mode 1PDU session
Outer local PDU session anchor point).
S2: when UE occurs mobile, since the service range of previous anchor point is extremely limited, network determines to select again for UE
PDU session anchor point 2.
Branch point Branching Point is arranged to PDU session anchor point 2 in S3:SMF.
S4:SMF specifies new IP address/prefix specified to UE.
S5:UE begins to use new IP address/prefix.
S6: old UE IP address/prefix discharges.
S7:SMF discharges the old branch of PDU session anchor point 1.
S8:SMF discharges Branching Point function.
As it can be seen that in the prior art, the local flow unloading branch of PDU session is without more perfect processor
System, for example when UE is in idle condition down and occurs mobile, constantly replaces local PDU session anchor point and bring a large amount of nets
Network signaling overheads.That is, the prior art for PDU session local flow unloading branch treatment mechanism there are nets
The larger technical problem of network signaling overheads.

UE subscription information, the mobility for the UE that network local policy etc. determines.For example, the management strategy is the mobile mould as UE
Formula is the mobile user of small range, then the SMF refusal deletes local PDU session flow and unloads branch's anchor point.If UE
It is the user moved on a large scale, for example UE is in high rail mode, then deletes local PDU session flow unloading simultaneously
Branch's anchor point.When detecting that current UE is in high rail mode, the SMF then deletes local according to the management strategy
PDU session flow unloads branch's anchor point.The business use pattern instruction user of UE uses the behavioural habits of network and business.
The management strategy can also be that the SMF according to the business use pattern of user, determines to delete local PDU session flow
Unload branch's anchor point.For example not will use the business of flow unloading in some period according to certain user, then directly entering the free time
Local PDU session flow is deleted when state unloads branch's anchor point.The local PDU session flow of operator unloads branch's anchor
The management strategy of point may be: as long as UE enters Idle state from connected state, SMF should delete all local PDU session stream
Amount unloading branch's anchor point.In the specific implementation process, the management strategy can be one or more of above several strategies
Combination, as long as the PDU session meets one of deletion condition, the SMF just deletes the PDU session stream
Amount unloading branch.Certainly, those skilled in the art can also be accustomed to design the management plan according to the actual use of user
Slightly, it is not limited in the situation of above several strategies, does not just repeat one by one herein.
In the embodiment of the present application, use Uplink classifier UL CL mode to the PDU in the SMF

High-speed mobile mode, and using Uplink Classifier mode carry out flow unloading when, then determine to delete the UE's
For PDU session flow unloads branch, specific implementation process is as shown in Figure 3.
Specifically, when UE becomes deactivation status from state of activation with the PDU session of flow unloading branch,
The release message of PDU session flow unloading branch is notified SMF by AMF.SMF is current according to the PDU session's of acquisition
The Move Mode of characteristic such as UE.Further, SMF decides whether that deleting PDU session flow unloads according to the mobility of UE
Carry branch.When determining the Move Mode is high-speed mobile mode, SMF determines to delete the PDU session flow unloading point
Branch, SMF send the deletion instruction for deleting PDU session flow unloading branch to UPF.Specifically, SMF is to UPF
While sending the tunnel instruction where deleting PDU session flow unloading branch, sends and delete SSC mode2PDU
Session flow unloads branch's anchor point (the local PDU session flow i.e. under UL CL implementation unloads branch's anchor point)
Instruction is deleted, and sends the deletion instruction for deleting Uplink Classifier.UPF responds above-mentioned deletion instruction, to corresponding
PDU session flow unloading branch is deleted.Further, network side continues to execute other PDU session flows and unloads
Ramifying is carried just not repeat one by one herein since specific process is compared with technology.
