Description

Quality of service control method, device, equipment and medium

Technical Field

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

Background

Currently, quality of service (Quality of Service, qoS) control is one of the main control strategies for hierarchical services of users in a mobile communication network, and users can apply for different service classes according to autonomous wish, and further enjoy different mobile communication services. Wherein, different service levels can be represented by different communication bandwidths, data traffic, priorities in the state of the user and the like enjoyed by the user.

In the current QoS control mode, a user normally applies for an initial QoS and accepts the QoS through a management system, so as to determine a QoS class, and the QoS class is registered and stored in subscription data after being determined by the management system. When a User accesses the network, a policy and charging rules function (Policy and Charging Rule Function, PCRF) generates QoS information according to subscription data and sends the QoS information to a base station and User Equipment (UE) to realize QoS updating.

However, the current QoS information is network-wide, and all QoS information related configurations require the base station to participate simultaneously with the core network, and for the QoS information configured by the network-wide, the coverage area of each base station is not subdivided, and the network-wide base station receives the QoS information. In a coverage area of a base station, a user performs QoS update on most services only locally calculated at multiple access edges (Multi-access Edge Computing, MEC) according to a unified QoS control policy of the whole network, which is not beneficial to reasonable scheduling and utilization of radio resources.

Detailed Description

Features and exemplary embodiments of various aspects of the present invention will be described in detail below, and in order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely configured to illustrate the invention and are not configured to limit the invention. It will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the invention by showing examples of the invention.

It is noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other like elements in a process, method, article or apparatus that comprises the element.

In the current QoS control mode, the core network generally receives a modification request and signs up, and when a user attaches, the sign-up data generates QoS information, which is transmitted from the core network to the base station and the terminal. Furthermore, the generation of QoS information may be triggered by modifying HSS subscription data, that is, qoS update may be triggered by traffic, that is, the upper layer application server recognizes that the user is using a certain subscription service, and initiates related operations to update QoS to the PCRF.

However, the current QoS information is network-wide, and all QoS information related configurations require the base station to participate simultaneously with the core network, and for the QoS information configured by the network-wide, the coverage area of each base station is not subdivided, and the network-wide base station receives the QoS information. And users in a certain base station coverage area, for most of services only local to MEC, or according to the unified QoS control strategy of the whole network, qoS updating is carried out, so that reasonable scheduling and utilization of wireless resources are not facilitated.

In view of this, the embodiments of the present invention provide a QoS control method, apparatus, device, and medium, where a MEC server may obtain a first QoS parameter of a UE connected to the UE, and send QoS information including the first QoS parameter and a UE identifier to an OAM entity, which does not need to participate in a core network, and the OAM entity may send QoS information to a base station to which the UE accesses, and does not need to send QoS information to a whole network base station.

Alternatively, in an embodiment of the present invention, the QoS control method may be applied to a QoS control system, which may include an MEC server, an OAM entity, a base station, and a UE. As one example, the QoS control system may be applied in long term evolution (Long Term Evolution, LTE). The QoS control method provided by the embodiment of the present invention is described below with reference to the accompanying drawings:

fig. 1 is a flowchart of a QoS control method according to an embodiment of the present invention, as shown in fig. 1, the QoS control method 100 may include S110 to S160.

S110, the MEC server acquires a first QoS parameter of the UE.

Optionally, in one embodiment, the MEC server may determine a preset QoS parameter corresponding to the UE according to the UE identifier of the UE, and determine the first QoS parameter according to the corresponding preset QoS parameter. The UE logs in on the MEC server, and the MEC server may provide MEC local service for the UE, and the UE identifier may include IMSI, that is, a mobile phone number. In one embodiment, in order to make the user use the service better, a second QoS parameter of the service currently used by the UE may be acquired, and the first QoS parameter is determined according to the second QoS parameter and a corresponding preset QoS parameter. Wherein the first QoS parameter may include at least one of the following: the QCI, ARP, preemption capability, preempted capability, specific description of the QCI can be as shown in table 1:

TABLE 1

It will be appreciated that QCI is a scale value for measuring packet forwarding behavior (e.g. packet loss rate, packet delay budget) for a particular offered service data flow, and it can be applied both to GBR and Non-GBR for specifying control bearer level packet forwarding means (e.g. scheduling weights, admission thresholds, queue management thresholds, link layer protocol configurations, etc.) defined within the access node, which can be preconfigured by the operator into the access network node.

S120, the MEC server sends QoS information to the OAM entity.

Wherein the QoS information may include a first QoS parameter of the UE and a UE identity of the UE. Alternatively, the OAM entity may be an OAM entity corresponding to a base station to which the UE accesses when using the MEC-local service.

And S130, the OAM entity receives the QoS information sent by the MEC server and sends the QoS information to the base station.

The base station may be a base station to which the UE accesses when using the MEC local service.

S140, the base station receives QoS information sent by the OAM entity, and determines whether the UE is accessed to the network according to the UE identification in the QoS information.

S150, when determining that the UE is accessed to the network, the base station generates RRC connection reconfiguration information according to the QoS information.

Alternatively, in one embodiment, the base station may generate the modified bearer request information according to the QoS information and generate the RRC connection reconfiguration information according to the modified bearer request information. As an example, the base station may check the QCI of the first QoS parameter in the QoS information to determine whether the resource type corresponding to the QCI is Non-GBR. When the corresponding resource type is Non-GBR, the base station generates modified bearing request information according to QoS information, and generates RRC connection reconfiguration information according to the modified bearing request information.

S160, the base station sends RRC connection reconfiguration information to the UE.

The RRC connection reconfiguration information may be used for the UE to update its air interface scheduling information according to the RRC connection reconfiguration information.

According to the QoS control method of the embodiment of the invention, the MEC server can acquire the first QoS parameter of the UE connected with the MEC server and send the QoS information comprising the first QoS parameter and the UE identifier to the OAM entity, the core network participation is not needed, the OAM entity can send the QoS information to the base station accessed by the UE without sending the QoS information to the whole network base station, when the UE is determined to be accessed to the network, the base station can generate RRC connection reconfiguration information according to the QoS information and send the RRC connection reconfiguration information to the UE for reconfiguration of the air interface scheduling information of the UE, so that when the UE uses the service of the MEC local, only the QoS parameter update is carried out on the base station where the UE is located, the reasonable scheduling and the utilization of wireless resources are facilitated, and the priority of the UE on the MEC local service can be determined based on the first QoS parameter.

In one embodiment, to determine whether the UE is network-connected more accurately, before determining whether the UE is network-connected according to the UE identification in the QoS information, the method may further include the steps of: when any UE accesses the base station, the base station may acquire the UE identity of any UE from any UE. This step is described below in connection with a specific example:

As shown in fig. 2, when the base station completes user registration or the UE is handed in from another base station, that is, when any UE accesses the base station, the base station may construct a Non-Access-Stratum (NAS) message, that is, an identification request (Indentity Request), where the identification request indicates that the UE is identified as IMSI, and then, based on the identification request, develop an identity identification procedure, the any UE returns its IMSI in an identification response (Indentity response), so that the UE identification of the any UE may be obtained and recorded in the context of the any UE in the base station for subsequent use.

Furthermore, the UE identification in the QoS information can be searched in the UE identification of any UE, when the UE identification in the QoS information is searched in the UE identification of any UE, the UE is determined to be in network connection, and when the UE identification in the QoS information is not searched in the UE identification of any UE, the UE is determined to be not in network connection, so that whether the UE is in network connection or not can be determined more accurately.

In one embodiment, in order to notify the MEC server that the air interface scheduling information of the UE has been updated, after sending the RRC connection reconfiguration information to the UE, the method may further include the steps of:

s170, the UE receives the RRC connection reconfiguration information sent by the base station, updates the air interface scheduling information of the UE according to the RRC connection reconfiguration information, and sends RRC connection reconfiguration completion information to the base station.

S180, the base station receives RRC connection reconfiguration completion information sent by the UE and sends Qos parameter response information to the OAM entity.

Wherein, the QoS parameter response information may be used to indicate that the UE has updated the air interface scheduling information of the UE according to the RRC connection reconfiguration information.

And S190, the OAM entity receives the Qos parameter response information sent by the base station and sends the QoS parameter response information to the MEC server.

S200, the MEC server receives the QoS parameter response information sent by the OAM entity.

In this way, the MEC server UE can be timely informed that the air interface scheduling information has been updated.

The QoS control method of the present invention will be described with reference to a specific embodiment, taking the example of updating QoS when a user logs in to an MEC server, and as shown in fig. 3, the QoS control method may include the following steps:

step 1, a user uses a service of MEC local, and needs to log in an MEC server first, when the user logs in, namely when the UE logs in the MEC server, the UE can send an IMSI to the MEC server, the MEC server can correlate and store the IMSI of the UE and the IP of the UE, and then when the UE is used as the service, the corresponding IMSI can be obtained through the IP inquiry of the UE. After the MEC server completes user login, the MEC server may determine, according to the IMSI of the UE, a preset QoS parameter corresponding to the IMSI among a plurality of preset QoS parameters, and determine the corresponding preset QoS parameter as a first QoS parameter, where each preset QoS parameter includes QCI, ARP priority, preemption capability, and preempted capability.

Wherein, the preset QoS parameters are preset, and the specific settings may be as shown in table 2:

TABLE 2

UE identity IMSI	QCI	ARP priority (1-15)	Preemption capability	Preempted capability
					UE1	9	10	Non-preemptive	Can be preempted
UE2	6	6	Preemptible to	Can not be preempted
					UE3	7	7	Preemptible to	Can be preempted
UE4	8	8	Non-preemptive	Can not be preempted

As an example, when the IMSI of the UE is UE1, the preset QoS parameter corresponding to the IMSI is QCI 9, arp priority is 10, preemption capability is non-preemption, preempted capability is preemptible, and then it is determined that the corresponding preset QoS parameter is the first QoS parameter.

Step 2, the MEC server may send QoS information to the OAM entity, the QoS information including the first QoS parameter of the UE and the IMSI of the UE. If the first QoS parameter is not determined, no further processing is performed.

Step 3, the OAM entity may receive QoS information sent by the MEC server, and send the QoS information to the base station.

And step 4, the base station can receive QoS information sent by the OAM entity, searches whether the UE is in the network or not according to the IMSI of the UE in the QoS information, and if so, executes step 5. If the network is not accessed, the network is not processed.

And 5, the base station can check the QCI of the first QoS parameter in the QoS information and determine whether the resource type corresponding to the QCI is Non-GBR. If yes, the base station may generate modified bearer request information, i.e. Modify Bearer Request information, according to the QoS information, and generate RRC connection reconfiguration information, i.e. RRC Connection Reconfiguration information, according to the modified bearer request information, and record the QoS information sent by the OAM entity. If not, the processing is not performed.

Step 6, the base station may send RRC connection reconfiguration information to the UE.

And 7, the UE can receive the RRC connection reconfiguration information sent by the base station, update the air interface scheduling information according to the RRC connection reconfiguration information and send RRC connection reconfiguration completion information to the base station.

In step 8, the base station may receive the RRC connection reconfiguration complete information sent by the UE, i.e. RRCConnection Reconfiguration Complete information, and determine Modify Bearer Request triggered by the OAM entity according to the recorded QoS information sent by the OAM entity, without sending the modified bearer response information, i.e. Modify Bearer Response information, to the mobility management entity (Mobility Management Entity, MME), and send QoS parameter response information to the OAM entity.

And 9, the OAM entity receives the Qos parameter response information sent by the base station and sends the QoS parameter response information to the MEC server.

Step 10, the MEC server receives QoS parameter response information sent by the OAM entity.

Therefore, when the user logs in the MEC local service, the QoS parameters corresponding to the user can be obtained, and the priority of the user in the MEC local service can be effectively distinguished based on the QoS parameters.

The QoS control method of the present invention will be described with reference to a specific embodiment, by taking dynamically updating QoS according to a service currently used by a user as an example, and as shown in fig. 4, the QoS control method may include the following steps:

Step 11, the MEC server may determine a preset QoS parameter corresponding to the IMSI from a plurality of preset QoS parameters according to the IMSI of the UE, and may obtain, according to current service data of the UE, a second QoS parameter of a service currently used by the UE, and determine the first QoS parameter according to the second QoS parameter and the corresponding preset QoS parameter.

Wherein, the second QoS parameters of the service are planned in advance by the operator, and the second QoS parameters may include QCI, and the specific form may be as shown in table 3:

TABLE 3 Table 3

Service type	QCI
		Service 1	5
Service 2	6
		Service 3	7
Service 4	8
		Service 5	9

As an example, in combination with table 2 and table 3, when the IMSI of the UE is UE1 and the UE is using service 1, then the preset QoS parameter corresponding to the IMSI is QCI 9, arp priority is 10, preemption capability is non-preemption, preempted capability is preemption, the second QoS parameter is QCI 5, and at this time, the first QoS parameter determined according to the second QoS parameter and the corresponding preset QoS parameter is QCI 5, arp priority is 10, preemption capability is non-preemption, and preempted capability is preemption.

Step 12, the MEC server may send QoS information to the OAM entity, the QoS information including the first QoS parameter of the UE and the IMSI of the UE. If the first QoS parameter is not determined, no further processing is performed.

Step 13, the OAM entity may receive QoS information sent by the MEC server, and send the QoS information to the base station.

Step 14, the base station may receive QoS information sent by the OAM entity, search whether the UE is network-connected according to the IMSI of the UE in the QoS information, and if so, execute step 15. If the network is not accessed, the network is not processed.

Step 15, the base station may check the QCI of the first QoS parameter in the QoS information, and determine whether the resource type corresponding to the QCI is Non-GBR. If yes, the base station can generate modified bearer request information according to the QoS information, generate RRC connection reconfiguration information according to the modified bearer request information, and record the QoS information sent by the OAM entity. If not, the processing is not performed.

In step 16, the base station may send RRC connection reconfiguration information to the UE.

Step 17, the UE may receive the RRC connection reconfiguration information sent by the base station, update its air interface scheduling information according to the RRC connection reconfiguration information, and send RRC connection reconfiguration complete information to the base station.

In step 18, the base station may receive RRC connection reconfiguration complete information sent by the UE, determine ModifyBearer Request triggered by the OAM entity according to the recorded QoS information sent by the OAM entity, and send QoS parameter response information to the OAM entity without sending modified bearer response information to the MME.

Step 19, the OAM entity receives the Qos parameter response information sent by the base station, and sends the Qos parameter response information to the MEC server.

Step 20, the MEC server receives the QoS parameter response information sent by the OAM entity.

Therefore, the relevant QoS parameters can be adjusted more quickly according to the QoS parameters corresponding to the user and the QoS parameters of the service, and the air interface scheduling efficiency of the service is guaranteed.

Based on the QoS control method of the embodiment of the present invention, the embodiment of the present invention further provides a QoS control apparatus, where the QoS control apparatus is applied to an MEC server, as shown in fig. 5, the QoS control apparatus 200 may include: an acquisition module 210 and a transmission module 220.
