In addition, terminal device to AMF send PDU session establishment request message when, specifically can be first by PDU session establishment Request message is sent to RAN, then the PDU session establishment request message is transmitted to AMF by RAN, is forwarding PDU session to AMF When establishing request message, RAN can also be to some other information of AMF forwarding terminal equipment, for example, the position of terminal device is believed Breath etc..

Optionally, the above-mentioned first information includes the second information, and the second information is to subscribe to permanent identification (Subscription Permanent Identifier, SUPI), data network name (Data Network name, DNN), single network slice choosing Select auxiliary information (Single Network Slice Selection Assistance Information, S-NASSI), industry Business instruction information, the instruction of implied warranty bit rate GBR service quality QoS stream, QoS index information (QoS Index) and QoS ginseng At least one of number information.

SPUI, DNN, S-NASSI can be AMF and disappear after receiving PDU conversation request message in the PDU session request The information added on the basis of breath, and business instruction information, QoS index information (QoS Index) and qos parameter information can be It carries among the PDU session request information that terminal device is sent.

Above-mentioned business instruction information specifically can be URLLC business instruction information (URLLC indication), work as business When the business for indicating information instruction is URLLC business, indicate that information can indicate that SMF is established in PDU session by the business Default GBR QoS flow.

Indicate that information by specific business (such as URLLC business) establish in PDU session indirectly by instruction with above-mentioned business The mode of default GBR QoS flow is compared, and above-mentioned implied warranty bit rate GBR service quality QoS stream instruction can be indicated directly SMF establishes default GBR QoS flow in PDU session.

Above-mentioned business instruction information and default GBR QoS flow instruction may be embodied in UE routing strategy (UE Route Selection Policy, URSP) in, it is that URLLC business indicates that information or default GBR QoS flow refer to business instruction information It is shown as example, the parameter that URSP includes is as shown in table 1.

Table 1

As shown in table 1, the URLLC parameter for including in URSP/default GBR QoS flow instruction can indicate above-mentioned business instruction Information can be write from memory by URLLC parameter/default GBR QoS flow instruction value to indicate whether to establish in PDU session Recognize GBR QoS flow.

For example, when URLLC parameter/default GBR QoS flow indicates a corresponding bit, when the value of the bit is 0 When indicate do not need in PDU session establish default GBR QoS flow, when the value of the bit be 1 when indicate need in PDU meeting Default GBR QoS flow is established in words (namely instruction SMF will establish default GBR QoS flow in PDU).

It should be understood that above-mentioned QoS index information and resource type can have certain corresponding relationship, QoS index information and money The correspondence relationship information of Source Type can store in SMF, and the corresponding relationship of QoS index information and resource type specifically can be as Shown in table 2.

Table 2

It should be understood that when in the first information include QoS index information when, SMF can by being parsed to the first information, with Obtain the QoS index information.It writes from memory next, SMF can determine whether to establish in PDU session according to QoS index information GBR QoS flow is recognized, as shown in table 2, when the index value that QoS index information indicates is any one index in X, Y, Z, M and N When, which is delayed key GBR, and SMF is determined establishes default GBR QoS in PDU session Stream.

102, SMF obtains PDU session management signing information from UDM.

Optionally, SMF obtains PDU session management signing information from UDM, comprising: SMF sends signing information request to UDM Message, the signing information request message carry the second information；SMF receives the PDU session management signing information that UDM is sent, PDU meeting Words management signing information includes defaulting the signing information of GBR QoS flow, wherein the signing information of default GBR QoS flow includes 5G Service quality identifies 5QI, distribution and reserved priority ARP, guarantees stream bit rates GFBR and maximum stream bit rates MFBR.

It should be understood that since SMF includes session establishment request message in the first information received, to trigger SMF To UDM request PDU session management signing information, for establishing session.

103, SMF establishes default GBR QoS flow in PDU session.

It should be understood that above-mentioned default GBR QoS flow, which can be, builds according to the QoS of default in a PDU session in 5G system The GBR QoS flow that vertical initial stage establishes and always exists in the life cycle of PDU session.

Whether disposed according to dynamic PCC, SMF establishes default GBR QoS flow in PDU session and is segmented into following two feelings Condition.

The first situation: dynamic PCC is disposed.

In one case, since dynamic PCC is disposed, SMF can obtain PDU conversation strategy information from UDM, And PDU conversation strategy information can be referred to when establishing default GBR QoS flow in PDU session.

Therefore, when dynamic PCC is disposed, method shown in Fig. 2 further includes step 105.

Step 105 specifically includes: SMF obtains PDU conversation strategy information from PCF.

Optionally, SMF obtains PDU conversation strategy information from UDM, comprising: SMF to PCF sending strategy information request message, Policy information request message carries the second information；SMF receives the PDU conversation strategy information that PCF is sent, PDU conversation strategy information Including default quality of service rule, default quality of service rule includes defaulting 5G service quality mark (the 5G QoS of GBR QoS flow Identifier, 5QI), distribution and reserved priority (Allocation and Retention Priority, ARP), guarantee Stream bit rates (Guaranteed Flow Bit Rate, GFBR) and maximum stream bit rates (Maximum Flow Bit Rate, MFBR)。

After getting PDU conversation strategy information, SMF can establish default GBR QoS flow in PDU session.

SMF establishes default GBR QoS flow in PDU session and specifically includes: SMF is according to the first information and PDU session pipe At least one of signing information and PDU conversation strategy two kinds of information of information are managed, defaults GBR QoS flow in PDU session establishment.

It should be understood that it is the session that terminal device is established that above-mentioned PDU session, which is SMF,.

Specifically, in the first scenario, it specifically includes following three kinds that SMF establishes default GBR QoS flow in PDU session Mode:

(1), default GBR QoS flow is established in PDU session with PDU session management signing information according to the first information；

(2), default GBR QoS flow is established in PDU session with PDU conversation strategy information according to the first information；

(3), according to the first information, session management policy information and PDU conversation strategy information established in PDU session it is silent Recognize GBR QoS flow.

Second situation: dynamic PCC is not disposed

In the latter case, since dynamic PCC is not disposed, SMF can not obtain PDU conversation strategy information from UDM, That is SMF can not be referring to PDU conversation strategy information when establishing default GBR QoS flow in PDU session.Since SMF is stored with Local PDU conversation strategy information, therefore, SMF are referred to local PDU when establishing default GBR QoS flow in PDU session Conversation strategy information.

Therefore, when dynamic PCC is not disposed, SMF establishes default GBR QoS flow in PDU session and specifically includes: SMF According in the first information and PDU session management signing information and two information of local PDU conversation strategy information at least One kind establishing default GBR QoS flow in the PDU session.

Specifically, in the first scenario, it specifically includes following three kinds that SMF establishes default GBR QoS flow in PDU session Mode:

501, UE sends session establishment request message to AMF.

Specifically, above-mentioned session establishment request message can be PDU session establishment request message, and session establishment request disappears Breath can be used for requesting to establish PDU session between UE and UPF.

In addition, PDU session establishment request message can be sent to AMF by RAN by UE.Specifically, UE first builds session Vertical request message is sent to RAN, which is transmitted to AMF again by RAN, and RAN is forwarding PDU meeting to AMF When words establish request message, some other information can also be forwarded to AMF, for example, the location information etc. of UE.

Above-mentioned session establishment request message may include the first information, which is used to indicate builds in PDU session The information of vertical implied warranty bit rate GBR service quality QoS stream, the first information can specifically include subscription permanent identification SUPI, data network name (Data Network name, DNN), single network slice selection auxiliary information (Single Network Slice Selection Assistance Information, S-NASSI), business indicate information, QoS index At least one of information and qos parameter information.

502, AMF is that UE selects SMF.

AMF can select SMF with itself, can also be sent to network function library facility (Network Function Repository Function, NRF), SMF is selected by NRF.DNN, network slice, signing can be considered when selecting SMF Information, the information such as local PDU conversation strategy information and load.

503, AMF sends session context request to create to SMF.

The specific context creation request in PDU session of the context creation request, can be in the context creation request The session establishment request message sent comprising UE to AMF.Further, which may include session establishment and asks Seek the first information in message.

504, SMF obtains subscription data.

Specifically, SMF can obtain PDU session signing information from UDM, obtain PDU conversation strategy information from PCF.

SMF obtains PDU session signing information from UDM, specifically includes: SMF sends signing information request message to UDM；SMF Receive the PDU session signing information that UDM is sent.

SMF obtains PDU conversation strategy information from PCF, specifically includes: SMF sends PDU conversation strategy information request to PCF Message；SMF receives the PDU conversation strategy information that PCF is sent.

It should be understood that above-mentioned signing information request message and PDU conversation strategy information request message can carry above-mentioned One information, PDU session signing information can carry the signing information of default GBR QoS flow, and PDU conversation strategy information can carry Default the policy information of GBR QoS flow.

505, SMF is according to the PDU conversation request message and PDU session signing information and PDU conversation strategy information two of UE At least one of kind information, establishes the PDU session comprising default GBR QoS flow.

The process for the default GBR QoS flow that SMF is established in PDU session and PDU session is referred to build in existing scheme The process of GBR QoS flow is established in vertical PDU session and PDU session.

After establishing default GBR QoS flow in PDU session, default GBR QoS flow transmission services number can use According to being described below with reference to Fig. 8 and Fig. 9 to using default GBR QoS flow transmission upstream data and the process of downlink data.

Fig. 8 is the flow chart using default GBR QoS flow transmission upstream data.Detailed process shown in Fig. 8 includes:

601, during PDU session establishment or PDU session modification, SMF sends signaling message to UE；

602, during PDU session establishment or PDU session modification, SMF sends signaling message to UPF；

603, it is later that upstream data determines a PDU session according to URSP that UE, which receives upstream data,；

604, after UE has determined PDU session, transmitting uplink data is arrived by unique radio resource of the PDU session RAN；

605, upstream data is sent to UPF by the tunnel N3 by RAN；

606, after UPF decapsulates upstream data, the data after obtaining are sent to DN.

It should be understood that in above-mentioned steps 601 and step 602, when in PDU session only comprising default GBR QoS flow without wrapping Containing other GBR QoS flows or when non-GBR QoS flow, the signaling message that SMF is sent to UE does not carry QoS Rule Information, SMF to Forward rule information is not carried in the signaling message that UPF is sent.

In addition, in step 603, when UE is there are when multiple PDU sessions, UE will determine that upstream data is corresponding according to URSP PDU session.

In step 605, for RAN after receiving upstream data, the ID of the session determined according to step 604 determines the meeting The corresponding tunnel N3 is talked about, upstream data is then sent to by UPF by the tunnel N3.

During transmitting upstream data, QoS Rule Information is not included in the signaling message that SMF is sent to UE and UPF With forward rule message, also, UE directly passes through unique radio resource of PDU session for transmitting uplink data to RAN, Neng Goujian Change the Signalling exchange during transmission upstream data, can further reduce the time delay of transmission downlink data.

Fig. 9 is the flow chart using default GBR QoS flow transmission downlink data.It is shown in Fig. 9 to specifically include:

701, during PDU session establishment or PDU session modification, SMF sends signaling message to UE；

702, during PDU session establishment or PDU session modification, SMF sends signaling message to UPF；

703, UPF receives the downlink data that DN is sent；

704, UPF determines a session according to UE IP, and is sent to downlink data by the corresponding tunnel N3 of the session RAN；

705, downlink data is sent to RAN by the tunnel N3 by UPF；

706, after RAN receives downlink data, according to the corresponding relationship in the tunnel N3 and radio resource, pass through corresponding wireless money Downlink data is sent to UE by source.

It should be understood that when only not including other GBR QoS flows or non-GBR comprising default GBR QoS flow in PDU session When QoS flow, in above-mentioned steps 701 and step 702, the signaling message that SMF is sent to UE does not carry QoS Rule Information, SMF to UPF send the signaling message in do not carry forward rule information, in step 703, UPF to RAN send downlink data when, It does not need to carry out QFI label to the data packet of downlink data.

During transmitting downlink data, QoS Rule Information is not included in the signaling message that SMF is sent to UE and UPF With forward rule message, also, UPF does not need to carry out the data packet of downlink data when sending downlink data to RAN yet QFI label, can simplify transmission downlink data during Signalling exchange, can further reduce transmission downlink data when Prolong.
