Description

Method and device for controlling quality of service

Technical Field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for controlling quality of service.

Background

In a mobile communication system, a QoS (quality of service) management mechanism is defined to complete quality of service control between a terminal equipment (UE) and a Core Network (CN). The core network configures, when the UE requests a service, QoS requirements for the corresponding service through subscription information, service characteristics, a network state, and other information of the UE, where the QoS requirements include a QoS Classification Identifier (QCI), a resource type (guaranteed rate class service and non-guaranteed cumulative rate service), a Packet Delay Budget (PDB), a Packet Error Rate (PER), and an Aggregate Maximum Bit Rate (AMBR). The QoS requirement is used to control the real-time quality of service of the end-to-end (E2E) path, which represents the path between the UE and the data network (data netwok), to ensure that the real-time quality of service of the end-to-end path meets the QoS requirement.

In a fifth generation (5G) system, a concept of network slicing is proposed, and due to the characteristic of high flexibility of a 5G network, a network topology can be flexibly changed, for example: a traditional core network and a wireless access network are relatively fixed topologies, a Protocol Data Unit (PDU) session in a 5G system can flexibly select different core networks and wireless access networks to be docked, and how to perform QoS control on a network slice in the 5G system is a hotspot of current research.

Disclosure of Invention

The technical problem to be solved by the embodiments of the present invention is to provide a QoS control method and apparatus. The quality of service of the wireless section in the end-to-end path can be controlled, increasing the flexibility of controlling the quality of service.

In order to solve the above technical problem, the present application provides a method for controlling QoS parameters, including: the core network element determines a first QoS requirement according to the QoS segmentation strategy and the end-to-end path QoS requirement, and the first QoS requirement is used for controlling the service quality of a wireless segment; and the core network element sends the first QoS requirement to the access network equipment and/or the terminal equipment, so that the access network equipment and/or the terminal equipment control the service quality of the wireless section according to the first QoS requirement.

The core network element is a network element in a core network, and the core network element includes but is not limited to one or more of a session management network element, an access management network element, and a policy control network element. The wireless section is a transmission path from the access network device to the terminal device, the network section is a transmission path from the access network device to the user plane network element, and the end-to-end path represents a transmission path from the terminal device to the user plane network element, that is, the end-to-end path includes the wireless section and the network section. The end-to-end QoS requirements are used to control the quality of service of the end-to-end path. The end-to-end QoS requirements may be pre-stored or pre-configured, for example: when a session is established, a core network element configures an end-to-end QoS requirement for the session. The QoS parameters include any one of packet delay budget, packet error rate and jitter, end-to-end QoS requirements, first QoS requirements and second QoS requirements in the present application.

According to the embodiment of the invention, a first QoS requirement is determined according to an end-to-end QoS requirement, and the first QoS requirement is sent to user equipment and/or access network equipment, so that the user equipment and/or the access network can perform QoS control on a wireless section according to the first QoS requirement.

In one possible design, the method further includes: and determining a second QoS requirement according to the end-to-end QoS requirement, and sending the second QoS requirement to the user plane network element and/or the access network equipment, wherein the network segment QoS is used for controlling the service quality of the network segment.

Wherein the second QoS requirement and the first QoS requirement cannot conflict with the end-to-end QoS requirement, for example: the QoS parameter is time delay, and the end-to-end QoS requirements are: the time delay is less than 10ms, and the time delay is an accumulation type parameter, so that the first QoS requirement is as follows: the time delay is less than 4ms, the second QoS requirement is less than 6ms, and then the first QoS requirement and the second QoS requirement meet the end-to-end QoS requirement. Another example is: the first QoS requirement is: the time delay is less than 4ms, and the second QoS requirement is as follows: and if the time delay is less than 7ms, the first QoS requirement and the second QoS requirement conflict with each other.

QoS segmentation policy is used to denote a rule for segmenting the end-to-end QoS requirements, where segmenting the end-to-end QoS requirements also requires consideration of whether the QoS segmentation parameters are accumulation type parameters or accumulation multiplication type parameters. For example: the QoS parameter is the packet error rate, and the end-to-end QoS requirement is: the error rate is less than 4 multiplied by 10 < -4 >, and the first QoS requirement after the end-to-end QoS requirement is segmented according to the QoS segmentation strategy is as follows: the error rate is < 1 x 10^ (-2), and the second QoS requirement is 4 x 10^ (-2).

In one possible design, the QoS segmentation policy may be related to one or more of traffic type, slice, and data network. For example: the same service type corresponds to the same QoS segmentation strategy; or the same slice corresponds to the same QoS segmentation strategy; or the same data network corresponds to the same QoS segmentation policy.

In one possible design, the QoS segmentation policy further relates to a first QoS capability and a second QoS capability, the first QoS capability representing a highest quality of service for the wireless segment, the second QoS capability representing a highest quality of service for the network segment, the first QoS requirement being higher than the second QoS requirement if the first QoS capability is higher than the second QoS capability; in the case where the first QoS capability is lower than the second QoS capability, the first QoS requirement is lower than the second QoS requirement.

And under the condition that the real-time service quality of the network section is lower than a second QoS requirement, improving the real-time service quality of the wireless section so that the real-time service quality of the end-to-end path meets the end-to-end QoS parameter.

Detailed Description

The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

Referring to fig. 1, a network architecture diagram of a communication system in an embodiment of the present invention is shown, where the communication system includes: a terminal device (UE), an access Network (NE), a user plane network element (UPF), a Data Network (DN), an access management network element (AMF), a session management network element (SMF), a policy control network element (PCF), a network data analysis network element (NWDAF), and an operation administration and maintenance network element (OAM) (not shown in fig. 1).

The UE and the RN communicate with each other through a Uu interface, the AN and the UPF communicate with each other through AN N3 interface, the UPF and the DN communicate with each other through AN N6 interface, the AMF and the UE communicate with each other through AN N1 interface, and the AMF and the AN communicate with each other through AN N2 interface. AMF, SMF, PCF and NWDAF are connected to the bus, AMF is connected with the bus through an Aamf interface, SMF is connected with the bus through an Nsmf interface, PCF is connected with the bus through an Npcf interface, and NWDAF is connected with the bus through an Nnwdaf interface.

The UE may be a handheld terminal, a notebook computer, a subscriber unit (subscriber unit), a cellular phone (cellular phone), a smart phone (smart phone), a wireless data card, a Personal Digital Assistant (PDA) computer, a tablet computer, a wireless modem (modem), a handheld device (hand), a laptop computer (laptop computer), a cordless phone (cordless phone) or a Wireless Local Loop (WLL) station, a Machine Type Communication (MTC) terminal or other devices that can access a network. The terminal equipment and the access network equipment are communicated with each other based on an air interface technology.

The RN is mainly responsible for functions such as radio resource management, QoS (quality of service) management, data compression and encryption on the air interface side. The access network equipment may include various forms of base stations, such as: macro base stations, micro base stations (also referred to as small stations), relay stations, access points, and the like. In systems using different radio access technologies, the names of devices with base station functionality may differ, for example: in the fifth generation (5th generation, 5G) system, referred to as gNB; in an LTE Long Term Evolution (LTE) system, referred to as an evolved node B (eNB or eNodeB); in the third generation (3G) system, the node b is called node b (node b).

The AMF belongs to a core network element and is mainly responsible for a signaling processing part, such as: access control, mobility management, attach and detach, and gateway selection. When the AMF provides a service for a session in the terminal device, it provides a storage resource of a control plane for the session, so as to store an SMF network element identifier associated with the session identifier and the like.

User data may also be received from the UE with the UPF over the RN, forwarded to the DN. The transmission resources and scheduling functions in the UPF serving the UE are managed and controlled by the SMF.

The PCF mainly supports providing a unified policy framework to control network behavior, providing policy rules to the control layer network functions, and being responsible for obtaining user subscription information related to policy decisions.

The NWDAF mainly supports the collection and analysis of big data and provides analysis results for other related network elements.

The OAM main use completes the daily operation activities of analyzing, predicting, planning and configuring the daily network and the service, testing the network and the service thereof, managing the fault and the like.

Referring to fig. 2, a schematic flow chart of a method for controlling quality of service according to an embodiment of the present invention is shown, where in the embodiment of the present invention, the method includes:

s201, the SMF determines a first QoS requirement according to the end-to-end QoS requirement.

Specifically, the end-to-end QoS requirement is used for controlling a quality of service of an end-to-end path, the end-to-end path including a wireless section and a network section, the first QoS requirement is used for controlling the quality of service of the wireless section; since the end-to-end path includes a wireless segment, the first QoS requirement cannot conflict with the end-to-end QoS requirement. The end-to-end QoS requirement may be configured by the policy control network element for the established session, and the session management policy of the session includes the end-to-end QoS requirement. The QoS parameters in the first QoS requirement and the end-to-end QoS requirement include one or more of PDB, PER, or Jitter; the QoS parameters are further divided into accumulation type parameters and multiplication type parameters, such as: the time delay is an accumulation type parameter, and the time delay of an end-to-end path is equal to the sum of the time delay of a wireless section and the time delay of a network section; for example: the packet error rate is a multiplicative parameter, and the packet error rate of the end-to-end path is equal to the product of the packet error rate of the wireless segment and the packet error rate of the network segment.

For example: referring to fig. 3, the end-to-end path includes a wireless segment and a network segment, the QoS parameter is a delay, and the end-to-end QoS requirement is: the time delay is less than or equal to 10ms, and the first QoS requirement is as follows: the time delay is less than or equal to 6ms, and the first QoS requirement also meets the end-to-end QoS requirement.

In a possible implementation, S201 further includes: determining a second QoS requirement according to the end-to-end QoS requirement, the second QoS requirement being used for controlling a quality of service of a network segment representing a transmission path between the RN to the UPF, the first QoS requirement and the second QoS requirement having to meet the end-to-end QoS requirement and not being able to conflict with the end-to-end QoS requirement, since the end-to-end path comprises a wireless segment and a network segment.

For example: the QoS parameter is time delay, and the end-to-end QoS requirements are: the time delay is less than 10ms, and the time delay is an accumulation type parameter, so that the first QoS requirement is as follows: the time delay is less than 4ms, the second QoS requirement is less than 6ms, and then the first QoS requirement and the second QoS requirement meet the end-to-end QoS requirement. Another example is: the first QoS requirement is: the time delay is less than 4ms, and the second QoS requirement is as follows: and if the time delay is less than 7ms, the first QoS requirement and the second QoS requirement conflict with each other.

In one possible embodiment, the method of determining the first QoS requirement and the second QoS requirement includes: and the SMF, the PCF, the NWDAF or the OAM carries out segmentation processing on the end-to-end QoS requirement according to the QoS segmentation strategy to obtain a first QoS requirement and a second QoS requirement. QoS segmentation policy is used to denote a rule for segmenting the end-to-end QoS requirements, where segmenting the end-to-end QoS requirements also requires consideration of whether the QoS segmentation parameters are accumulation type parameters or accumulation multiplication type parameters. For example: the QoS parameter is the packet error rate, and the end-to-end QoS requirement is: the error rate is less than 4 multiplied by 10 < -4 >, and the first QoS requirement after the end-to-end QoS requirement is segmented according to the QoS segmentation strategy is as follows: the error rate is < 1 x 10^ (-2), and the second QoS requirement is 4 x 10^ (-2).

Wherein the QoS segmentation policy is related to one or more of traffic type, slice, data network. For example: the same service type corresponds to the same QoS segmentation strategy; or the same slice corresponds to the same QoS segmentation strategy; or the same data network corresponds to the same QoS segmentation policy. When a session is established, a corresponding QoS segmentation strategy is determined according to the service type of the session, or the corresponding QoS segmentation strategy is determined according to the slice where the session is located, or the corresponding QoS segmentation strategy is determined according to the data network where the session is located.

Wherein the QoS segmentation policy further relates to a first QoS capability and a second QoS capability, the first QoS capability representing a highest quality of service of the wireless segment, the second QoS capability representing a highest quality of service of the network segment, the first QoS requirement being higher than the second QoS requirement in case the first QoS capability is higher than the second QoS capability; in the case where the first QoS capability is lower than the second QoS capability, the first QoS requirement is lower than the second QoS requirement. The first QoS capability and the second QoS capability may be evaluated during a session or during a non-session, and the specific evaluation process is described with reference to fig. 4 and 5.

For example: the QoS parameter is exemplified by latency, the first QoS capability: delay 1ms, second QoS capability: delay is 3ms, end-to-end QoS requirement: the time delay is less than 6ms, in order to fully utilize the QoS capability of a wireless section and a network section, a first QoS capability obtained after a QoS segmentation strategy is decomposed and segmented is as follows: delay < 2ms, second QoS capability: the delay is less than 4 ms.

In a possible implementation manner, the method further includes S206: the process of acquiring the QoS segmentation policy includes any one of the following:

A. prior to establishing a session, the SMF receives QoS segmentation policies from the NWDA or OAM, from which the SMF derives the session-associated QoS segmentation policies. And when the QoS segmentation strategy is updated, the NWDA or the OAM informs the SMF of the updated QoS segmentation strategy.

B. Before establishing a session, the PCF receives a QoS segmentation strategy from the NWDA or the OAM, the PCF sends the obtained QoS segmentation strategy to the SMF, and the SMF obtains the QoS segmentation strategy for session management. When the QoS segmentation policy is updated, the NWDA or OAM notifies the PCF of the updated QoS segmentation policy.

C. The SMF sends a first request message to the PCF, the first request message for requesting a session management policy (session management policy) for the session, the first request message carrying one or more of a traffic type identifier, a network slice identifier, a data network identifier, and a QoS parameter type identifier, the PCF receiving the first request message from the SMF, the PCF sending a message to the NWDA or OAM for requesting a QoS segmentation policy, the message carrying one or more of a traffic type identifier, a network slice identifier, a data network identifier, and a QoS parameter type identifier, the NWDA or OAM receiving the request message, determining an associated QoS segmentation policy based on the one or more of a traffic type identifier, a network slice identifier, a data network identifier, and a QoS parameter type identifier, the NWDA or OAM sending the QoS segmentation policy to the PCF, and then sending a first response message to the SMF, the first response message including a session management policy, the session management policy includes the QoS segmentation policy.

The NWDA or OAM may send a plurality of QoS segmentation policies to the PCF, and the PCF selects one QoS segmentation policy among the plurality of QoS segmentation policies and sends the selected QoS segmentation policy to the SMF.

The message sent by PCF to NWDA or OAM for requesting QoS subsection strategy also carries strategy selection indication, and the strategy selection indication is used for indicating the priority for distributing the first QoS requirement and the second QoS requirement. For example: the first QoS requirement is preferentially assigned or the second QoS requirement is preferentially assigned.

D. In the process of establishing a session, the SMF sends a second request message to the NWDA or OAM, where the second request message carries one or more of a service type identifier, a slice type identifier, a data network identifier, and a QoS parameter type identifier, the NWDA or OAM determines a corresponding QoS segmentation policy according to the identifiers, and the NWDA or OAM sends the determined QoS segmentation policy to the SMF.

The second request message may further carry a policy selection indication, where the policy selection indication is used to indicate the priority for allocating the first QoS requirement and the second QoS requirement. For example: the strategy selection indication is represented by bits, and when the strategy selection indication is equal to 1, the first QoS requirement is preferentially allocated; when the policy selection indication is equal to 0, it indicates that the second QoS requirement is preferentially allocated.

S202, the SMF sends the first QoS requirement to the AMF, and the AMF receives the first QoS requirement from the SMF.

For example: the AMF issues the first QoS requirement to the AMF via a N1N 2 message transfer (Namf _ communication _ N1N 2 message transfer).

S203, the AMF sends a first QoS requirement to the AN, and the AN receives the first QoS requirement from the AMF.

For example: the AMF generates the first QoS requirement to the AN through a session modification message (N2 session mod) or a session setup message (N2 session setup).

S204, the AN sends a first QoS requirement to the UE, and the UE receives the first QoS requirement from the AN.

For example: the AN sends the first QoS requirement to the UE through AN RRC reconfiguration message (RRC reconfig).

S205, the UE and the AN control the quality of service of the wireless segment according to the first QoS requirement.

In one possible embodiment, the method further comprises:

s207, when the reconfiguration condition is met, the SMF reconfigures the QoS segmentation strategy.

The reconfiguration triggering condition for triggering the reconfiguration QoS segmentation strategy comprises any one of the following conditions:

1. the NWDAF or the OAM sends a QoS subsection change instruction to the PCF, wherein the QoS subsection change instruction is used for indicating that the first QoS requirement or the second QoS requirement needs to be reconfigured, and the PCF sends the QoS subsection change instruction to the SMF to trigger the SMF to reconfigure the first QoS requirement or the second QoS requirement.

2. The NWDAF or the OAM sends a QoS section change indication to the SMF, the QoS section change indication is used for indicating that the first QoS requirement or the second QoS requirement needs to be reconfigured, and the SMF reconfigures the first QoS requirement or the second QoS requirement according to the QoS section change indication.

3. The RN sends a message to the SMF through the AMF to indicate that the real-time service quality of a wireless section does not meet a first QoS requirement, the SMF receives the message to trigger the reconfiguration of the first QoS requirement and improve the real-time service quality of a network section so that the real-time service quality of an end-to-end path meets the end-to-end QoS requirement; and the RN sends a message to the SMF through the AMF to indicate that the real-time service quality of the network segment does not meet the second QoS requirement, the SMF receives the message to trigger the reconfiguration of the second QoS requirement and improve the real-time service quality of a wireless segment, so that the real-time service quality of an end-to-end path meets the end-to-end QoS requirement.

4. And the UPF sends a message to the SMF to indicate that the real-time service quality of the network segment does not meet the second QoS requirement, and the SMF receives the message to trigger the reconfiguration of the second QoS requirement and improve the real-time service quality of the wireless segment so that the real-time service quality of the end-to-end path meets the end-to-end QoS requirement.

The SMF may apply the reconfigured first QoS requirement or the reconfigured second QoS requirement to the currently established session or the re-established session, and the method for applying the reconfigured first QoS requirement or the reconfigured second QoS requirement to the session may refer to the steps described in fig. 2, which are not described herein again.

Wherein, in case the real-time quality of service of the wireless segment is lower than the first QoS requirement, the SMF increases the real-time quality of service of the network segment such that the real-time quality of service of the end-to-end path meets the end-to-end QoS requirement.

Specifically, in the case where the real-time quality of service of the wireless segment is lower than the first QoS requirement, and the real-time quality of service of the end-to-end path is lower than the end-to-end QoS requirement, the SMF reconfigures the first QoS requirement of the wireless segment and improves the real-time quality of service of the network segment so that the real-time quality of service of the end-to-end path satisfies the end-to-end QoS requirement.

For example: the QoS parameter is latency, the first QoS requirement: delay < 6ms, second QoS requirement: delay < 4ms, end-to-end QoS requirement: delay < 10ms, assuming real-time quality of service for the wireless segment: delay is 9ms, real-time service quality of network segment: delay is 2ms, real-time service quality of end-to-end path: delay is 11ms > end-to-end QoS requirement, then the real-time quality of service of the wireless segment is lower than the first QoS requirement, and the SMF reconfigures the first QoS requirement: the time delay is less than or equal to 9ms, meanwhile, the SMF improves the real-time service quality of the network segment, and the improved real-time service quality of the network segment is assumed: 0.5ms, then the real-time quality of service of the end-to-end path at this time: 9ms +0.5ms is 9.5ms < 10ms, and the end-to-end QoS requirement is met.

The method for improving the real-time service quality of the network segment comprises the following steps:

reselecting a UPF with high real-time service quality for the session; or
