The method that the transmission information of the application proposition is described below, this method can be applied to control plane and use under RQ mechanism The scene interacted between the face of family.

It should be noted that the title of network element AMF, SMF, PCF described herein should not be to the skills of the embodiment of the present application Art forecast scheme configuration limits.For example, in some communication systems, have some network elements title may with network element described herein The title of AMF, SMF, PCF are not quite similar, but if these network elements have and AMF, SMF, PCF phase in the embodiment of the present application Congenerous, these network elements should also fall into the protection scope of the embodiment of the present application.

The method of the transmission information of the embodiment of the present application is described in detail below.

Firstly, whether UE can be supported by register flow path or session process to network side transmission for the angle of UE The information of RQ.

Mode 1

UE sends the first instruction information to AMF by register flow path, and the first instruction information is used to indicate the reflection service of UE Quality RQ ability.Wherein, RQ ability can characterize whether UE supports RQ.

It is the example that UE sends whether UE supports the information of RQ by register flow path referring to Fig. 3, Fig. 3.

301, user equipment (UE) sends the first instruction information by register flow path.AMF receives first by register flow path and refers to Show information.For example, the first instruction information can be sent to AMF by login request message by UE.

Wherein, the first instruction information is used to indicate whether UE supports RQ.Specifically, the first instruction information can be UE RQ Capability.One kind is possible to be achieved in that, the first instruction information is there are two types of value, and a kind of value is corresponding to support RQ, separately A kind of value is corresponding not to support RQ.For example, the first instruction information value indicates to support RQ when being 1, the first instruction information is taken It indicates not support RQ when value is 0.

First instruction information may be used to indicate that UE supports RQ, i.e., the first instruction information only has a kind of value, for referring to Show and supports RQ.

In the embodiment of the present application, RQ mechanism refer to upstream data packet use and the consistent QoS flow of downlink data packet into Row transmission.Whether the UE stated in text supports RQ, can also be expressed as whether UE supports RQ mechanism.Whether network uses RQ, It can be expressed as whether network uses RQ mechanism.

AMF can know that UE supports RQ according to the first instruction information.AMF executes step 302.

302, the first instruction information is sent to SMF by session process by AMF.For example, AMF can pass through AMF's and SMF In interaction message Nsmf_PDUSession_CreateSMContext Request, the first instruction information is sent to SMF.

303, SMF first indicates that information is sent to PCF.For example, SMF can pass through Npcf_SMPolicyControl_Get Serviceization message is sent to PCF.

In the present embodiment, the first instruction information is sent to SMF by session process by AMF, for by SMF or PCF root The control strategy to SDF is determined according to the first instruction information.

It is understood that AMF after getting the first instruction information in login request message, first can be indicated Information preservation is got off.Then AMF indicates information for first again by the first instruction Information encapsulation in session management context message It is sent to SMF.After SMF receives the first instruction information, then by first instruction Information encapsulation sent in event open notification message To PCF.

304, PCF determines the control strategy of SDF according to the first instruction information.

Specifically, the subscription data of the available UE of PCF and/or the subscription data and/or business information of DNN granularity, and According at least one in the subscription data of UE, the subscription data of DNN granularity, business information, the first instruction information, determine to industry The control strategy (control strategy can also be referred to as) of business data flow (service data flow, SDF).

It should be noted that the subscription data of UE includes the subscription data of UE and the subscription data of DNN granularity in UDR.? Described subscription data refers to the subscription data of DNN granularity in step 304.

In Fig. 3 of mode 1, in a kind of possible situation, PCF is according to the signing number for connecing the DNN granularity obtained from UDR According in conjunction with the first instruction information received, the determining control strategy to SDF.

In the case where alternatively possible (shown in non-Fig. 3), PCF can also be according to the DNN granularity obtained from UDR Subscription data determines the control strategy to SDF.

305, PCF sends the control strategy of SDF to SMF.

Wherein, the control strategy of SDF is included in PCC rule.

UE is according to control strategy, it is determined whether detects to the RQ field of downlink data packet.

For example, UE is to the first SDF's if control strategy is that network uses RQ to some SDF (being hereafter denoted as the first SDF) The RQ field of downlink data packet is detected.If control strategy is that network does not use RQ to the first SDF, UE is to the first SDF's The RQ field of downlink data packet does not detect.

Specifically, in the embodiment shown in fig. 3, after PCF has determined control strategy, one the 4th finger is sent to SMF Show information, whether the 4th instruction information instruction network uses RQ.SMF reprocesses the 4th instruction information, generates second and refers to Show information.Second indication information is sent to UE by SMF.UE can know whether network uses RQ according to second indication information.

Alternatively, be also possible to after PCF determined control strategy, by SMF to sending wireless access network (radio Access network, RAN) the 5th instruction information is sent, the 6th instruction information is generated according to the 5th instruction information by RAN and is sent To UE.UE can know whether network supports RQ according to the 6th instruction information.

Therefore, a network element (such as network element A) described in the embodiment of the present application is sent out to another network element (such as network element B) It delivers letters breath, can be network element A and directly send information to network element B, and without other network elements, the information also network element A not issued Make any processing (that is, transparent transmission).Alternatively, be also possible to network element A issue information after, by other network elements or network forwarding or To information by Resealing, finally by network element B receive one Reseal after information.In other words, no matter network element A Whether the information of sending and the packing forms of the network element B information received are identical, we think the information that network element A is issued With the identical meaning of the network element B information representation received.The embodiment of the present application does not limit the mistake Resealed to information Journey does not limit the network element Resealed to information yet.Those skilled in the art can be in the technical solution that the application provides On the basis of, it is contemplated that others transformation or feasible pattern.

In the embodiment of the present application, RQ field may also be referred to as RQ marker (RQ identifier bit).

In addition, the RQ field of the data packet of the first SDF is marked in SMF instruction UPF.

If second indication information indicates that network uses RQ, SMF to indicate UPF to the downlink data of the first SDF the first SDF Packet makees the first label.If second indication information indicates that network does not use RQ, SMF to indicate UPF to the first SDF's the first SDF Downlink data packet makees the second label.For example, the first label can be " 1 ", second is labeled as " 0 ".

Still optionally further, for second indication information instruction network using in the case where RQ, second indication information also indicates net The granularity for the RQ that network is supported.Wherein, the granularity of RQ includes business data flow SDF granularity, Packet Data Unit PDU session grain Degree, data network DN granularity or UE granularity.

In method flow shown in Fig. 3, PCF is according to the first instruction information received, it is determined whether adopts to some SDF Use RQ.Another example is provided below with reference to Fig. 4, in this example of Fig. 4, determines whether to use some SDF by SMF RQ。

Referring to fig. 4, Fig. 4 is another example that UE sends whether UE supports RQ by register flow path.

401, UE sends the first instruction information by register flow path, and AMF receives the first instruction information by register flow path.

402, the first instruction information is sent to SMF by AMF.

403, SMF determines the control strategy to SDF according to the first instruction information and local policy.

In addition, SMF according to the determining control strategy to SDF, indicates that the data packet of some SDF is marked in UPF.Example Such as, if network uses RQ, SMF to indicate UPF in the RQ ratio in the encapsulation packet header of the downlink data packet of the first SDF the first SDF Make the first label in special position, such as labeled as 1.If network does not use RQ, SMF to indicate UPF in the first SDF the first SDF Downlink data packet encapsulation packet header RQ bit in make the second label, such as labeled as 0.The is sent with by session process One instruction information is compared, and the signaling overheads for reporting the first instruction information can effectively be saved by being sent by register flow path.

In the embodiment illustrated in figure 4, SMF receives strategy and charging control (policy and from PCF Charging control, PCC) rule, and combine PCC rule and the first instruction information that the control strategy to SDF has been determined.

If SMF can also root in alternatively possible implementation in such as network in the case where no deployment PCF According to local policy and the first instruction information, the control strategy to SDF is determined.

Wherein, local policy can be the generations such as the business information of DNN RQ subscription data, UE.In other words, in net In network in the case where no deployment PCF, subscription data, the business information etc. of UE are configured on Ying SMF, in order to which SMF is according to this A little information and/or data generate local policy.Further, the first instruction information is received in SMF or third indicates information In the case of, in conjunction with the first instruction information and local policy, perhaps combine third instruction information and local policy or in conjunction with first Indicate that information, third instruction information and local policy determine the control strategy to SDF.(can hereafter it make about third instruction information It is discussed in detail)

In Fig. 3 and embodiment shown in Fig. 4 of mode 1, UE sends whether UE supports to network side by register flow path The first instruction information of RQ.It, can be effective by register flow path transmission compared with sending the first instruction information by session process Save the signaling overheads for reporting the first instruction information.

Mode 2

UE sends third to SMF by session process and indicates that information, third instruction information are used to indicate the meaning that UE uses RQ It is willing to.

It is the example that UE sends whether UE uses the wish of RQ by session process referring to Fig. 5, Fig. 5.

501, UE sends third to SMF and indicates information, and SMF receives third and indicates information.

Above in Fig. 3 and Fig. 4, UE is used to indicate user equipment (UE) by the first instruction information that register flow path is sent RQ ability, RQ ability supports RQ for characterizing UE or do not support RQ.In Fig. 5, UE is sent to the of SMF by session process Three instruction information are used to indicate a kind of wish whether UE uses RQ.

The granularity of the wish of RQ can be SDF granularity, PDU session granularity, DN granularity or UE granularity.The application does not limit It is fixed.

Therefore, in the foregoing embodiments, the first instruction information specifically can be with UE RQ Capability.And herein Three instruction information are specifically as follows RQ Preference.

In step 501, UE sends third to AMF by session process and indicates information, and AMF forwards third instruction information To SMF.That is, AMF does not interpret the content of third instruction information, and being only will be from the third of UE in session process Instruction information is transmitted to SMF.

502, third instruction information is transmitted to PCF by SMF, and accordingly, PCF receives third and indicates information.

For example, SMF can be indicated third by the Npcf_SMPolicyControl_Get service message of session process Information is sent to PCF.

Similarly, third instruction information is transmitted to PCF by SMF, to indicate that information is determined to SDF's according to third by PCF Control strategy.

503, PCF indicates information according to third, determines the control strategy to SDF.

In step 503, specifically, the subscription data of the available UE of PCF and/or the subscription data of DNN granularity and/or Business information, and according at least one in the subscription data of UE, the subscription data of DNN granularity, business information, third instruction information , determine the control strategy to SDF.

In the embodiment of the present application, business information includes but is not limited to the QoS demand information of business.In addition, referred to herein Subscription data refer to the subscription data of DNN granularity.

504, PCF sends the control strategy of SDF to SMF.

Subsequent, SMF indicates whether network uses RQ to UE according to control strategy, by AMF.

Specifically, if network uses RQ, SMF that can send RQ allowed to UE by AMF.If network does not use RQ, then SMF can send RQ not allowed to UE by AMF.

Further, whether UE uses the instruction information of RQ according to the network received, it is determined whether to downlink data packet RQ field detected.If that UE is received is RQ allowed, UE detects the RQ field of downlink data packet.If That UE is received is RQ not allowed, then UE does not detect the RQ field of downlink data packet.

In addition, SMF is according to second indication information, it is also necessary to indicate that UPF marks to the RQ field of downlink data packet.According to Different meanings indicated by second indication information, UPF make different labels to the RQ field of downlink data packet.For example, if second Indicate that information instruction network uses RQ, then SMF indicates that UPF makees the first label to downlink data packet.If second indication information indicates Network does not use RQ, then SMF indicates that UPF makees the second label to downlink data packet.For example, the first label can be " 1 ", the second mark It is denoted as " 0 ".

Optionally, in the case where second indication information instruction network uses RQ, second indication information also indicates network branch Hold the granularity of RQ, wherein the granularity of RQ includes SDF granularity, PDU session granularity, DN granularity or UE granularity.

As it can be seen that compared with the embodiment shown in the figure 3 above of embodiment shown in Fig. 5, instruction that UE is sent to network side Information is different.The first instruction information that UE is sent in Fig. 3 is used to indicate the RQ ability of user equipment (UE), and RQ ability is used RQ is supported in characterization UE or does not support RQ.And the third instruction information that UE is sent in Fig. 5 is used to indicate the meaning whether UE uses RQ It is willing to, indicates that UE uses a kind of wish of RQ.

It is another example that UE sends whether UE uses the wish of RQ by session process referring to Fig. 6, Fig. 6.

601, UE sends third to SMF by session process and indicates information, and SMF receives the first instruction letter by session process Breath.

Wherein, third instruction information is used to indicate the wish whether UE uses RQ.Specifically, third instruction information can be RQ Preference。

In this application, the UE routing strategy (UE that RQ Preference can be sent according to the network that UE is received Route selection policy, URSP) it generates, can also otherwise, the embodiment of the present application is not construed as limiting.

Specifically, UE forwards third to indicate information by AMF to SMF, and AMF does not interpret the content of third instruction information.

602, SMF indicates information and local policy according to third, determines the control strategy to SDF.

Here, the PCC rule that PCF is generated is to the control strategy to SDF described in the embodiment of the present application.Namely It says, in this scheme, the control strategy to SDF is generated by PCF.

Specifically, PCF, which is sent in the PCC rule of SMF, may include RQ control information.Wherein, RQ control Information is used to indicate the control strategy to SDF.

First, which is sent, by register flow path with UE indicates that the embodiment of information is similar, in the embodiment shown in fig. 6, SMF Control management to SDF also includes following two aspects.

(1) whether SMF uses RQ to UE instruction network, in order to which UE determines whether to carry out the RQ field of downlink data packet Detection.

If SMF indicates that network uses RQ, UE to detect the RQ field of downlink data packet.If SMF indicates network not Using RQ, then UE does not detect the RQ field of downlink data packet.

(2) SMF indicates that the RQ field of downlink data packet is marked in UPF.

RQ, SMF is used to indicate UPF in the encapsulation packet header of the downlink data packet of the first SDF the first SDF if SMF is determined RQ bit in make first label.RQ, SMF is not used to indicate UPF in the downlink of the first SDF the first SDF if SMF is determined Make the second label in the RQ bit in the encapsulation packet header of data packet.For example, the first label can be " 1 ", second is labeled as " 0 ". Or it does not mark.

In conclusion UE (specifically reports whether UE supports to AMF) to network side by register flow path in mode 1 The first instruction information of RQ.It is the first instruction reported by network element PCF according to UE in embodiment shown in Fig. 3 in mode 1 Information determines whether network uses RQ in conjunction with the subscription data and/or business information of UE.In the implementation shown in Fig. 4 of mode 1 It is to determine whether network uses in conjunction with the local policy on SMF according to the first instruction information that UE is reported by network element SMF in example RQ。

In mode 2, UE passes through session process to network side (specifically to the SMF) wish for reporting UE whether to use RQ Third indicates information.It is the third instruction letter reported by network element PCF according to UE in embodiment shown in fig. 5 in mode 2 Breath, in conjunction with the subscription data of UE and/or the subscription data and/or business information of DNN granularity, determines whether network uses RQ.? It is that information is indicated according to the third that UE is reported by network element SMF, in conjunction with the local on SMF in the embodiment shown in fig. 6 of mode 2 Strategy, determines whether network uses RQ.

From the point of view of combination 1 and mode 2, in mode 1, UE is reported in RQ ability and mode 2 by register flow path passes through meeting Words process reports RQ ability to compare, and can save the transfer resource of UE to AMF.

And employing mode 2, UE can report the wish for supporting RQ, enable UE according to oneself actual demand to network The wish for whether supporting RQ sent.

Mode 3

UE sends the first instruction information by register flow path, and sends third by session process and indicate information.

In mode 3, UE is realized by the process that register flow path sends the first instruction information can in way of reference 1.UE is logical Session process is crossed to send the process of third instruction information realize can in way of reference 2.Which is not described herein again.

It should be noted that mode 3 is unlike foregoing manner 1 and mode 2, and in mode 3, the PCF or SMF of network side It can determine whether network uses RQ in conjunction with the first instruction information and third instruction information.

With PCF as an example, PCF receive the first instruction information and third instruction information after, in conjunction with first instruction information Determine whether network uses RQ with third instruction information.Specifically, PCF can according to the subscription data and/or business information of UE, Determine whether network uses RQ in conjunction with the first instruction information and third instruction information.

SMF be also it is similar, repeat no more.

In a kind of possible situation, PCF can obtain the subscription data of the DNN granularity of UE from subscribed database UDR, and Information is indicated in conjunction with the first instruction information and third, determines the control strategy to SDF.

In a kind of possible situation, SMF can based on the received from PCF PCC rule, in conjunction with first instruction information Information is indicated with third, determines the control strategy to SDF.

In addition, can also include a kind of situation, SMF is according to local policy, the first instruction information and third in mode 3 It indicates information, determines the control strategy to SDF.For example, in a network without deployment PCF in the case where, on Ying SMF configuration or Prestore the subscription data and/or business information of UE.SMF receive to first instruction information and third instruction information in the case where, Generate local policy according to the subscription data of the DNN granularity for the UE being locally stored and/or business information, and combine local policy, First instruction information and third indicate information, determine the control strategy to SDF.

PCF based on by upper type 1, in a manner of 2 and mode 3 in any one mode determine to the control strategy of SDF so that PCF determines that control strategy relates to more information, therefore, true according only to subscription data of UE and/or business information etc. with PCF Fixed to compare to the control strategy of SDF, control strategy can be more accurate and reasonable.

In addition, for SMF by local policy, combination 1, mode 2 or mode 3 are determined to the control strategy of SDF In the case of, it can not be disposed under the scene of PCF in a network, improve the method that network formulates RQ corresponding strategies.
