It should be noted that each entity shown in fig. 1 may be a single device physically, or two or more entities may be integrated on the same physical device, and the embodiment of the present invention is not limited.
Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Example one
Referring to fig. 2, a flowchart of a method for adjusting QoS according to AN embodiment of the present invention may also be understood as AN information interaction diagram between AN entity and AN SMF entity in a network architecture provided in fig. 1, where a process of the method may be described as follows:
s101: AN access network AN receives a first flow guaranteed bit rate GFBR and self-adaptive code rate adjustment information of a QoS flow sent by a session management function SMF entity; wherein the adaptive code rate adjustment information is used for adjusting the first GFBR;
s102: and when the wireless resources of the AN are less than the wireless resources required by the first GFBR of the QoS flow, the AN adjusts the first GFBR to be a second GFBR, wherein the second GFBR is the GFBR determined by the AN according to the adaptive code rate adjustment information, and the value of the second GFBR is less than that of the first GFBR.
In S101, the QoS flow may be formed by aggregating different PCC rules by the SMF entity.
The PCC rule of a Service Data Flow (SDF) level may include a QoS requirement and a Guaranteed Bit Rate (GBR) of a corresponding SDF, where the QoS requirement may include a 5G QoS Indicator (5G QoS Indicator, 5QI) and an Allocation and Retention Priority (ARP), and the GBR may be used to guarantee a code Rate of a Service.
Optionally, for the service with an adjustable code rate, the PCC rule may further include a QoS adjustable indication and an SDF candidate code rate.
The first GFBR of an aggregated QoS flow may be the sum of the GBRs of the SDFs aggregated to that QoS flow. For example, assuming that the PCC rules aggregated by the SMF entity include PCC rule 1, PCC rule 2, PCC rule 3, and PCC rule 1 includes GBR1, PCC rule 2 includes GBR2, and PCC rule 2 includes GBR3, the value of the first GFBR of the GoS flow after the SMF entity aggregates PCC rule 1, PCC rule 2, PCC rule 3 may be the sum of GBR1, GBR2, and GBR 3.
The AN may receive QoS flow requirements of a QoS flow sent by the SMF entity and adaptive code rate adjustment information, where the QoS flow requirements may include 5QI, ARP and the first GFBR, and the adaptive code rate adjustment information may be used to adjust the first GFBR.
Optionally, the adaptive code rate adjustment information may be divided into, but not limited to, the following two cases:
in case one, the adaptive code rate adjustment information may be a candidate GFBR value of a first GFBR of the QoS stream, and the candidate GFBR value may be smaller than the value of the first GFBR.
In this case, the setting of the candidate GFBR may be performed in two ways, including but not limited to:
in the method (1), the SMF entity may determine the GBR value of the SDF with the lowest GBR requirement in the QoS flow as the candidate GFBR value of the QoS flow.
In the method (2), the SMF entity may determine the SDF candidate code rate of the SDF including the QoS tunable indication in the PCC rule as a candidate GFBR value of the QoS flow.
In case two, the adaptive code rate adjustment information may be a candidate GFBR list of a first GFBR of the QoS stream; wherein the candidate GFBR list comprises at least one GFBR value.
After receiving the QoS flow requirement of the QoS flow sent by the SMF entity, the AN may allocate wireless resources to the QoS flow according to the QoS flow requirement of the QoS flow, so as to ensure that data may be transmitted according to the required quality of service.
Since the radio resources may change dynamically, in S102, when the radio resources of the AN are less than the radio resources required by the first GFBR of the QoS flow, that is, the radio resources cannot guarantee the first GFBR in the QoS flow requirement, the AN may adjust the first GFBR to be a second GFBR, where the second GFBR is a GFBR determined by the AN according to the adaptive code rate adjustment information, and the value of the second GFBR is less than the value of the first GFBR.
That is, in the embodiment of the present invention, when the radio resource cannot guarantee the first GFBR of the QoS stream, the AN may downgrade the first GFBR, that is, the AN adjusts the first GFBR to the second GFBR, and the value of the second GFBR is smaller than the value of the first GFBR, so that at least part of the services aggregated in the QoS stream can be guaranteed to be performed normally, or at least the services aggregated in the QoS stream can be guaranteed to be performed under a lower QoS requirement, thereby reducing the influence of radio resource change on the user service and improving the user experience. .
For different cases of the above adaptive code rate adjustment information, there are various implementations of S102, which will be described as an example below.
Alternatively, for the case one described above, that is, when the adaptive code rate adjustment information is a candidate GFBR value of the first GFBR of the QoS stream, the AN may adjust the first GFBR to the candidate GFBR value.
That is, when the adaptive code rate adjustment information of the QoS stream received by the AN includes a candidate GFBR value of the first GFBR, and when the radio resources of the AN cannot guarantee the radio resources required by the first GFBR, the AN adjusts the first GFBR to a candidate GFBR value smaller than the first GFBR, so that at least part of the traffic aggregated to the QoS stream can be guaranteed to be performed normally, or at least that the traffic aggregated to the QoS stream can be continued with a lower QoS requirement.
Optionally, for the second case, when the adaptive code rate adjustment information is a candidate GFBR list of a first GFBR, the AN may adjust the first GFBR to a second GFBR, including:
the AN may determine a second GFBR from the list of candidate GFBRs based on its own algorithm and then adjust the first GFBR to the second GFBR.
That is, the candidate GFBR list of the first GFBR may include at least one candidate GFBR value, and when the radio resources cannot guarantee the radio resources required by the first GFBR, the AN may determine a second GFBR from the at least one candidate GFBR according to its own algorithm, and then downgrade the first GFBR to the second GFBR, so as to ensure that at least part of the traffic aggregated to the QoS flow can proceed normally, or ensure that at least the traffic aggregated to the QoS flow can proceed with a lower QoS requirement.
Or, if each GFBR value in at least one GFBR value in the candidate GFBR list has a corresponding code rate adjustment priority, for example, GFBR value a corresponds to code rate adjustment priority a, GFBR value B corresponds to code rate adjustment priority B, and GFBR value C corresponds to code rate adjustment priority C, where the code rate adjustment priority is, from high to low: a > B > C. Of course, in practical application, the priority of code rate adjustment may be set according to the size of the corresponding GFBR value, or a user may also customize the GFBR value according to actual requirements, specifically using what kind of method, which is not limited in the embodiment of the present invention.
Therefore, when the radio resources cannot guarantee the radio resources required by the first GFBR, the AN may determine a second GFBR according to the code rate adjustment priority of each of the at least one GFBR value of the candidate GFBR list, and then adjust the first GFBR to the second GFBR.
Of course, optionally, the AN may adjust the first GFBR to a second GFBR, including: if the wireless resources of the AN cannot guarantee the wireless resources required by any candidate GFBR value in the adaptive code rate adjustment information, the AN may directly release the QoS flow and send the indication information of releasing the QoS flow to the SMF entity. That is, after receiving the QoS stream transmitted by the SMF entity, and the first stream of the QoS stream, the first stream guaranteed bit rate GFBR and the adaptive code rate adjustment information, if the radio resource of the AN cannot guarantee the radio resource required by any candidate GFBR value of the first GFBR indicated by the adaptive code rate adjustment information, the AN side may directly release the QoS stream received from the SMF entity, and the AN side may transmit to the SMF entity AN indication information that may be used to instruct the SMF entity to release the corresponding QoS stream of the local side.
For different situations of the adaptive code rate adjustment information, the AN may send the adjustment information to the SMF entity after adjusting the first GFBR to the second GFBR, and at this time, the process of sending the adjustment information may be divided into the following two situations:
a. if the adaptive code rate adjustment information sent by the SMF entity to the AN is the candidate GFBR value of the first GFBR, the AN may feed back the first adjustment information to the SMF entity after degrading the first GFBR, that is, the AN only needs to notify the SMF entity that it has degraded the first GFBR. After the SMF entity receives the first adjustment information, the SMF entity may determine, according to the first adjustment information, that the second GFBR after the AN adjustment is the candidate GFBR sent by the SMF entity to the AN. Then, the SMF entity may determine, according to the candidate GFBR, a PCC rule that needs to be deleted or updated in the QoS flow, or, if the PCC rule corresponding to the candidate GFBR includes an SDF indicated by QoS tunable, the SMF may downgrade the GBR of the PCC rule to a PCC rule of an SDF candidate code rate.
b. If the adaptive code rate adjustment information sent by the SMF entity to the AN is the candidate GFBR list of the first GFBR, the second adjustment information sent by the AN to the SMF entity may include the second GFBR after the AN downgrades the first GFBR. Since the SMF entity sends the candidate GFBR list of the first GFBR to the AN, after receiving the second adjustment information, the SMF entity may determine, according to the second GFBR in the second adjustment information, the PCC rule that needs to be deleted or updated, and if the PCC rule corresponding to the second GFBR includes the SDF indicated by QoS tunable, the SMF entity may downgrade the GBR of the PCC rule to the PCC rule of the SDF candidate code rate.
In the method for adjusting QoS according to the embodiment of the present invention, AN access network AN receives a first stream guaranteed bit rate GFBR and adaptive code rate adjustment information of a QoS stream sent by a session management function SMF entity, where the adaptive code rate adjustment information is used to adjust the first GFBR; then, when the wireless resources of the AN are less than the wireless resources required by the first GFBR of the QoS flow, the AN adjusts the first GFBR to a second GFBR according to the adaptive code rate adjustment information, and the value of the second GFBR is less than the value of the first GFBR. That is, in the embodiment of the present invention, when the radio resource of the AN cannot guarantee the GFBR of the QoS stream, the GFBR is degraded, that is, the AN adjusts the first GFBR to a second GFBR whose value is smaller than that of the first GFBR, thereby ensuring that the service aggregated in the QoS stream can be performed normally, reducing the influence of the radio resource change on the user service, and improving the user experience.
Example two
Based on the same inventive concept, please refer to fig. 3, AN embodiment of the present invention provides a method for adjusting QoS, which can also be understood as AN information interaction diagram among AN entity AN, AN SMF entity and a PCF entity in the network architecture provided in fig. 1, where the process of the method can be described as follows:
s201: a Session Management Function (SMF) entity receives at least one Policy and Charging Control (PCC) rule of a Service Data Flow (SDF) level, wherein each PCC rule in the at least one PCC rule comprises a Guaranteed Bit Rate (GBR) of a corresponding SDF;
s202: the SMF entity aggregates at least one PCC rule to the QoS flow and determines a first flow guaranteed bit rate (GFBR) and adaptive code rate adjustment information of the QoS flow; wherein the adaptive code rate adjustment information is used for adjusting the first GFBR;

in the first mode, the SMF entity determines the self-adaptive code rate adjustment information of the QoS flow according to the GBR.
The SMF entity aggregates the PCC rules to obtain the QoS flow, and the SMF entity can determine that the GBR requirement is the lowest from the GBRs corresponding to the PCC rules aggregated into the QoS flow, namely the GBR value with the lowest GBR value is the adaptive code rate adjustment information of the QoS flow, namely the candidate GFBR value of the first GFBR; alternatively, the SMF entity may determine, as the candidate GFBR value of the first GFBR, a sum of GBRs of a part of the PCC rules of the plurality of PCC rules aggregated to the QoS flow; alternatively, the SMF entity may determine two or more GBR values from multiple GBRs corresponding to multiple PCC rules in the QoS flow as candidate GFBRs of the first GFBR, that is, the adaptive code rate adjustment information determined by the SMF entity may be a candidate GFBR list including two or more GBR values; alternatively, the SMF entity may determine a sum of GBRs of any two or more PCC rules of the multiple PCC rules aggregated to the QoS flow as a candidate GFBR of the first GFBR, that is, the adaptive code rate adjustment information determined by the SMF entity is a candidate GFBR list, where each GFBR value in the candidate GFBR list may be the sum of GBRs of the two or more PCC rules. Optionally, the SMF may configure a code rate adjustment priority for each value in the candidate GFBR list, or the SMF may automatically match the code rate adjustment priority corresponding to each value according to the size of each value in the candidate GFBR list.

That is, the SMF entity may determine that the candidate GBR with the smallest median among the at least one candidate GBR corresponding to the at least one PCC rule is the candidate GFBR value of the first GFBR; alternatively, the SMF entity may determine the sum of the at least one candidate GBR value as the candidate GFBR value of the first GFBR; alternatively, the SMF entity may determine a candidate GFBR list of the first GFBR according to at least one candidate GBR, and optionally, the SMF entity may configure a code rate adjustment priority for each GFBR value in the candidate GFBR list.
Of course, in practical applications, the SMF entity may determine the adaptive code rate adjustment information of the QoS stream in any one or more of the manners described above, and the present invention is not limited in particular.
In S203, the SMF entity may send the first stream guaranteed bit rate GFBR and the adaptive code rate adjustment information of the QoS stream to the access network AN.
Optionally, after the SMF entity sends the QoS flow requirement and the adaptive code rate adjustment information of the QoS flow to the access network AN, the SMF entity may receive the first adjustment information or the second adjustment information fed back by the AN
If the adaptive code rate adjustment information sent by the SMF entity to the AN is the candidate GFBR value of the first GFBR, after the SMF entity receives the first adjustment information fed back by the AN, the SMF entity may determine, according to the first adjustment information, that the second GFBR after the adjustment by the AN is the candidate GFBR sent by the SMF entity to the AN, and may determine, according to the candidate GFBR, a PCC rule that needs to be deleted or updated in the QoS flow, and the SMF entity feeds back, to the PCF entity, the PCC rule that needs to be deleted, or the PCC rule that needs to downgrade the GBR to the candidate GBR of the SDF.
Or, since the SMF sends the candidate GFBR list of the first GFBR to the AN, after receiving the second adjustment information, the SMF may determine the PCC rule that needs to be deleted or updated according to the second GFBR in the second adjustment information, and the SMF entity feeds back the PCC rule that needs to be deleted to the PCF entity, or the PCC rule that needs to downgrade the GBR to the candidate GBR of the SDF.
In the embodiment of the invention, when the SMF entity determines the self-adaptive code rate adjustment information of the QoS flow, the self-adaptive code rate adjustment information of the QoS flow can be determined according to each GBR in at least one PCC rule; or if each PCC rule of a part of PCC rules in the at least one PCC rule further includes a candidate GBR of the corresponding SDF, the SMF entity may determine adaptive bitrate adjustment information of the QoS flow according to the GBR and the candidate GBR; or if each PCC rule in the at least one PCC rule further includes a candidate GBR of the corresponding SDF, the SMF entity determines the adaptive bitrate adjustment information of the QoS stream based on the candidate GBR, that is, the determination of the adaptive bitrate adjustment information may be determined according to the GBR and/or the candidate GBR, which improves the accuracy of the adaptive bitrate adjustment information, and further ensures the accuracy when the AN adjusts the first GFBR.

Based on the same inventive concept, please refer to fig. 4, where fig. 4 is a flowchart of another method for adjusting QoS in AN embodiment of the present invention, and it can also be understood that, in the network architecture provided in fig. 1, when AN entity is connected to AN auxiliary AN entity, AN information interaction diagram between the AN entity and the auxiliary AN entity is shown, and a process of the method may be described as follows:
s301: the auxiliary access network AN receives first flow guaranteed bit rate GFBR and self-adaptive code rate adjustment information of a QoS flow sent by the access network AN; the auxiliary AN is connected with the AN, and the adaptive code rate adjustment information is used for adjusting the first GFBR;
s302: when the wireless resources of the auxiliary AN are less than the wireless resources required by the first GFBR of the QoS flow, the auxiliary AN adjusts the first GFBR to a second GFBR, wherein the value of the second GFBR is less than that of the first GFBR;
s303: the assisting AN sends the adjustment information to the AN.
In the embodiment of the present invention, for the case of dual connection, in S301, AN may send the QoS flow requirement and adaptive code rate adjustment information of the QoS flow received from the SMF entity to AN auxiliary AN connected thereto, and the auxiliary AN allocates corresponding wireless resources for the QoS flow to ensure that data can be transmitted according to the required quality of service, and the QoS flow is successfully established.
The QoS flow requirement may include 5QI, ARP and the first GFBR, and the adaptive code rate adjustment information may be used to adjust the first GFBR.
Of course, in practical applications, the AN may be connected to a plurality of auxiliary ANs, and the AN may select two or more auxiliary ANs from the connected plurality of ANs according to actual requirements to select and determine the wireless resources, which is not limited in the present invention.
Optionally, the adaptive code rate adjustment information may be divided into, but not limited to, the following two cases:
in case one, the adaptive code rate adjustment information may be a candidate GFBR value of a first GFBR of the QoS stream, and the candidate GFBR value may be smaller than the value of the first GFBR.
In this case, the setting of the candidate GFBR may be performed in two ways, including but not limited to:
in the method (1), the SMF entity may determine the GBR value of the SDF with the lowest GBR requirement in the QoS flow as the candidate GFBR value of the QoS flow.
In the method (2), the SMF entity may determine the SDF candidate code rate of the SDF including the QoS tunable indication in the PCC rule as a candidate GFBR value of the QoS flow.
In case two, the adaptive code rate adjustment information may be a candidate GFBR list of a first GFBR of the QoS stream; wherein the candidate GFBR list comprises at least one GFBR value.
In S302, when the radio resource of the auxiliary AN is smaller than the radio resource required by the first GFBR of the QoS flow, that is, when the radio resource of the auxiliary AN cannot guarantee the GFBR required by the QoS flow, the auxiliary AN may adjust the first GFBR to a second GFBR according to the adaptive code rate adjustment information, where a value of the second GFBR is smaller than a value of the first GFBR.
Optionally, in view of the first condition, if the adaptive code rate adjustment information received by the auxiliary AN is the candidate GFBR value of the first GFBR, the adjustment information sent by the auxiliary AN to the AN may be the first adjustment information, and the subsequent AN may feed back the first adjustment information to the SMF entity.
For the second case, if the adaptive code rate adjustment information received by the auxiliary AN is the candidate GFBR list of the first GFBR of the QoS stream, the adjustment information that the auxiliary AN may send to the AN is the second adjustment information, where the second adjustment information includes the second GFBR, and the subsequent AN may feed back the second adjustment information to the SMF entity.
In the embodiment of the present invention, the access network AN is connected to AN auxiliary access network AN, and the auxiliary access network AN receives the first stream guaranteed bit rate GFBR and the adaptive code rate adjustment information of the QoS stream sent by the access network AN, when the wireless resource of the auxiliary AN is smaller than the wireless resource required by the first GFBR of the QoS stream, the auxiliary AN adjusts the first GFBR to a second GFBR based on the adaptive code rate adjustment information, and the value of the second GFBR is smaller than the value of the first GFBR, and the auxiliary AN sends the adjustment information to the AN. That is, after receiving the first stream guaranteed bit rate GFBR and adaptive code rate adjustment information of the QoS stream, the AN sends these information to the auxiliary access network AN connected to the AN, and the auxiliary AN allocates radio resources, and if the radio resources are insufficient, the AN adjusts the first GFBR to the second GFBR, and then sends the adjustment information to the AN, thereby reducing the information processing pressure of the AN and improving the efficiency.
