The preferred embodiment of the present invention is described in detail with reference to the accompanying drawing.
Embodiment one
Fig. 2 is referred to, is a kind of flow chart of the method for adjustment of service quality QoS provided in an embodiment of the present invention, it can also
To be interpreted as under the network architecture of Fig. 1 offer, information exchange schematic diagram between AN entity and SMF entity, the process of this method
It can be described as follows:
S101: access net AN receives the first-class ensures bit rate GFBR for the QoS flow that conversation management functional SMF entity is sent
With self-adaption code rate adjustment information；Wherein, self-adaption code rate adjustment information is for adjusting the first GFBR；
S102: when the radio resource needed for the first GFBR that the radio resource of AN is less than QoS flow, AN adjusts the first GFBR
It is the GFBR that AN is determined according to self-adaption code rate adjustment information for the 2nd GFBR, the 2nd GFBR, and the value of the 2nd GFBR is less than institute
State the value of the first GFBR.
In S101, QoS flow, which can be, by SMF entity to be polymerized different PCC rules.
It wherein, may include corresponding SDF in the PCC rule of business data flow (Service Data Flow, SDF) rank
Qos requirement and ensures bit rate (Guaranteed Bit Rate, GBR), qos requirement may include 5G QoS instruction (5G
QoS Indicator, 5QI) and distribute and keep priority (Allocation and Retention Priority, ARP),
GBR can be employed to ensure that the code rate of business.
Optionally, business adjustable for code rate, PCC rule in can also include QoS it is adjustable instruction and SDF Candidate key
Rate.
First GFBR of the QoS flow after polymerization can be to be aggregated to the sum of GBR of SDF of the QoS flow.For example, false
If the PCC rule of SMF entity polymerization includes PCC rule 1, PCC rule 2, PCC rule 3, and PCC rule 1 includes GBR1, PCC rule
Then 2 include GBR2, and PCC rule 2 includes GBR3, then the GoS after PCC rule 1, PCC rule 2, PCC rule 3 polymerize by SMF entity
The value of first GFBR of stream can be the sum of GBR1, GBR2 and GBR3.
The QoS flow that AN can receive the QoS flow of SMF entity transmission requires and self-adaption code rate adjustment information, wherein QoS
Stream may include 5QI, ARP and the first GFBR in requiring, and self-adaption code rate adjustment information can be used for adjusting the first GFBR.
Optionally, self-adaption code rate adjustment information can be divided into but be not limited only to following two situation:
Situation one, self-adaption code rate adjustment information can be the candidate GFBR value of the first GFBR of QoS flow, candidate GFBR value
The value of the first GFBR can be less than.
In this case, the setting of candidate GFBR may include but be not limited only to following two mode and carry out:
Mode (1), SMF entity can require GBR in QoS flow the GBR value of minimum SDF to be determined as the time of the QoS flow
Select GFBR value.
SDF candidate's code rate of SDF including the adjustable instruction of QoS in PCC rule can be determined as by mode (2), SMF entity
The candidate GFBR value of QoS flow.
Situation two, self-adaption code rate adjustment information can be the candidate GFBR list of the first GFBR of QoS flow；Wherein, it waits
Selecting GFBR list includes at least one GFBR value.
After receiving the QoS flow of QoS flow of SMF entity transmission and requiring, AN can be wanted AN according to the QoS flow of QoS flow
Ask as the QoS flow distributing radio resource, with ensure data can service quality as requested transmitted.
And since radio resource may dynamically change, in S102, when the radio resource of AN is less than QoS flow
When radio resource needed for the first GFBR, i.e., when radio resource not can guarantee a GFBR in QoS flow requirement, AN can be by first
GFBR is adjusted to the 2nd GFBR, the GFBR that the 2nd GFBR determines for AN according to self-adaption code rate adjustment information, and the 2nd GFBR's
It is worth the value less than the first GFBR.
I.e. in the embodiment of the present invention, when radio resource not can guarantee a GFBR of QoS flow, AN can be to the first GFBR
Degrade, i.e. the first GFBR is adjusted to the 2nd GFBR, value of the value less than the first GFBR of the 2nd GFBR, at least may be used by AN
It can be normally carried out with the business that guarantee section is aggregated in the QoS flow, or at least guarantee that the business for being aggregated in the QoS flow can be with
Business is carried out under lower qos requirement, is reduced influence of the radio resource variation to customer service, is improved user experience.
For the different situations of above-mentioned self-adaption code rate adjustment information, S102 can there are many implementations, will lift below
Example is illustrated.
Optionally, the candidate for above situation one, i.e., as the first GFBR that self-adaption code rate adjustment information is QoS flow
When GFBR value, the first GFBR can be adjusted to candidate GFBR value by AN.
That is, the self-adaption code rate adjustment information for the QoS flow that AN is received includes the candidate GFBR value of the first GFBR
When, when the radio resource needed for the radio resource of AN not can guarantee the first GFBR, then the first GFBR is adjusted to be worth smaller by AN
Candidate GFBR value, the communication service that the QoS flow can be at least aggregated to guarantee section can be normally carried out, or at least can be with
The communication service for ensuring to be aggregated in the QoS flow can be continued with lower qos requirement.
Optionally, for above situation two, when self-adaption code rate adjustment information is the candidate GFBR list of the first GFBR,
First GFBR can be adjusted to the 2nd GFBR by AN, comprising:
AN can determine the 2nd GFBR based on itself algorithm from candidate GFBR list, and the first GFBR is then adjusted to the
Two GFBR.
It may include at least one candidate's GFBR value in the candidate GFBR list of the first GFBR, and when radio resource can not
When radio resource needed for guaranteeing the first GFBR, AN can determine second from least one candidate GFBR according to itself algorithm
Then first GFBR is downgraded to the 2nd GFBR by GFBR, can at least be aggregated to the communication service of the QoS flow with guarantee section
To be normally carried out, or at least may insure the communication service for being aggregated in the QoS flow can be continued with lower qos requirement into
Row.
Alternatively, if each GFBR value at least one GFBR value in candidate's GFBR list has its corresponding code rate tune
Whole priority, for example, GFBR value A corresponds to code rate adjustment priority A, GFBR value B corresponds to code rate adjustment priority B, C pairs of GFBR value
Code rate adjusts priority C, wherein code rate adjusts priority from high to low are as follows: A > B > C.Certainly, in practical applications, code rate
Adjustment priority can be set according to the size of corresponding GFBR value, alternatively, user can also carry out according to actual needs
It is customized, it is specifically carried out using which kind of mode, the embodiment of the present invention is with no restriction.
Therefore, when the radio resource needed for radio resource not can guarantee the first GFBR, AN can be according to candidate GFBR list
At least one GFBR value in each GFBR value code rate adjustment priority determine the 2nd GFBR, then the first GFBR is adjusted to
2nd GFBR.
Certainly, optionally, the first GFBR is adjusted to the 2nd GFBR by AN, comprising: if the radio resource of AN can not be protected
When radio resource needed for hindering any one of self-adaption code rate adjustment information candidate's GFBR value, AN can directly discharge the QoS
Stream, and the instruction information for discharging QoS flow is sent to SMF entity.That is, AN receive SMF entity transmission QoS flow,
And after the first-class ensures bit rate GFBR and self-adaption code rate adjustment information of QoS flow, if the radio resource of AN can not be protected
When radio resource needed for hindering the candidate GFBR value of any one the first GFBR indicated by self-adaption code rate adjustment information, the side AN can
Directly to discharge the QoS flow received from SMF entity, and the side AN can send an instruction information, the instruction to SMF entity
Information can serve to indicate that SMF entity discharges the corresponding QoS flow of local side.
For the different situations of above-mentioned self-adaption code rate adjustment information, AN can by the first GFBR be adjusted to the 2nd GFBR it
Afterwards, adjustment information is sent to SMF entity, the process for sending adjustment information at this time can be divided into the following two kinds situation:
If a, the self-adaption code rate adjustment information that SMF entity is sent to AN is the candidate GFBR value of the first GFBR, AN exists
After degrading to the first GFBR, can only need to notify to SMF Entity feedback the first adjustment information, i.e. AN SMF entity its
Degrade to the first GFBR.For SMF entity after receiving the first adjustment information, SMF entity can be according to the first adjustment
Information determines that AN the 2nd GFBR adjusted is the candidate GFBR that SMF entity issues AN.Then, SMF entity can be according to candidate
GFBR determines the PCC rule for needing to delete or update in QoS flow, alternatively, if including in the corresponding PCC rule of candidate GFBR
The SDF for instruction that QoS is adjustable, then SMF can PCC rule GBR be downgraded to SDF candidate's code rate PCC rule.
If b, the self-adaption code rate adjustment information that SMF entity is sent to AN is the candidate GFBR list of the first GFBR, AN
After degrading to the first GFBR, being sent in the second adjustment information of SMF entity may include the 2nd GFBR.Due to
What SMF entity was sent to AN is the candidate GFBR list of the first GFBR, and therefore, SMF entity, can after receiving second adjustment information
To determine the PCC rule for needing to delete or update according to the 2nd GFBR in second adjustment information, if the 2nd GFBR is corresponding
Include the SDF of the adjustable instruction of QoS in PCC rule, then SMF entity can the GBR of PCC rule be downgraded to SDF candidate's code rate
PCC rule.
