Description

Service quality control methods, devices, equipment and media

Technical field

The present invention relates to the field of wireless communication technology, and in particular, to a service quality control method, device, equipment and medium.

Background technique

Currently, Quality of Service (QoS) control is one of the main control strategies for user-graded services in mobile communication networks. Users can apply for different service levels according to their own wishes, and then enjoy different mobile communication services. Among them, different service levels can be represented by different communication bandwidths, data traffic, and priorities in user status enjoyed by users.

Under the current QoS control mode, users usually apply independently in the initial QoS state and accept it through the management system to determine the QoS level. After the level is determined by the management system, they are registered and stored in the contract data. When a user accesses the network, the Policy and Charging Rule Function (PCRF) generates QoS information based on the subscription data and sends it to the base station and User Equipment (UE) to implement QoS updates.

However, the current QoS information is network-wide, and all QoS information-related configurations require the participation of base stations and core networks at the same time. The QoS information configured for the entire network is not subdivided into the coverage area of each base station. All network-wide base stations must receive QoS information. . However, when users are within the coverage area of a certain base station, for most services that are only local to Multi-access Edge Computing (MEC), QoS updates are still carried out according to the unified QoS control policy of the entire network, which is not conducive to the use of wireless resources. Reasonable scheduling and utilization.

In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are configured only to explain the invention and not 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 illustrating examples of the invention.

It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that these entities or operations are mutually exclusive. any such actual relationship or sequence exists between them. Furthermore, the terms "comprises," "comprises," or any other variations thereof are intended to cover a non-exclusive inclusion such that a process, method, article, or apparatus that includes a list of elements includes not only those elements, but also those not expressly listed other elements, or elements inherent to the process, method, article or equipment. Without further limitation, an element defined by the statement "comprising..." does not exclude the presence of additional identical elements in a process, method, article, or device that includes the stated element.

Currently, in the current QoS control model, the core network usually accepts the modification request and signs a contract. When the user attaches, the contract data generates QoS information and is sent from the core network to the base station and terminal. In addition, the generation of QoS information can be triggered by modifying the HSS subscription data. That is to say, the QoS update can be triggered by the service. That is, the upper-layer application server recognizes that the user is using a certain subscription service and initiates related operations to update the QoS to the PCRF.

However, the current QoS information is network-wide, and all QoS information-related configurations require the participation of base stations and core networks at the same time. The QoS information configured for the entire network is not subdivided into the coverage area of each base station. All network-wide base stations must receive QoS information. . However, when users are within the coverage area of a certain base station, for most services that are only local to the MEC, QoS updates are still carried out according to the unified QoS control strategy of the entire network, which is not conducive to the reasonable scheduling and utilization of wireless resources.

In response to this, embodiments of the present invention provide a QoS control method, device, equipment and medium. The MEC server can obtain the first QoS parameter of the UE connected to it, and send the first QoS parameter and the UE identifier to the OAM entity. The QoS information does not require the participation of the core network, and the OAM entity can send QoS information to the base station that the UE accesses, without sending QoS information to the base stations of the entire network. When it is determined that the UE has accessed the network, the base station can generate RRC connection reconfiguration based on the QoS information. information and sent to the UE for reconfiguration of the UE's air interface scheduling information. In this way, when the UE uses MEC local services, only the QoS parameters of the base station where the UE is located can be updated, which is conducive to the reasonable scheduling and utilization of wireless resources. It also The priority of the UE's local service in the MEC may be determined based on the first QoS parameter.

Optionally, in embodiments of the present invention, the QoS control method can be applied to a QoS control system, and the QoS control system can include a MEC server, an OAM entity, a base station, and a UE. As an example, the QoS control system can be applied in Long Term Evolution (LTE). The QoS control method provided by the embodiment of the present invention is introduced below with reference to the accompanying drawings:

Figure 1 is a schematic flowchart of a QoS control method provided by an embodiment of the present invention. As shown in Figure 1, the QoS control method 100 may include S110 to S160.

S110. The MEC server obtains the first QoS parameter of the UE.

Optionally, in one embodiment, the MEC server may determine the preset QoS parameters corresponding to the UE based on the UE identity of the UE, and determine the first QoS parameters based on the corresponding preset QoS parameters. Among them, the UE logs in to the MEC server, and the MEC server can provide MEC local services for the UE. The UE identification can include the IMSI, that is, the mobile phone number. In one embodiment, in order to enable the user to better use the service, the second QoS parameter of the service currently used by the UE may be obtained, and the first QoS parameter may be determined based on the second QoS parameter and the corresponding preset QoS parameter. The first QoS parameter may include at least one of the following options: QCI, ARP, preemption capability, and preempted capability. The specific description of QCI may be as shown in Table 1:

Table 1

It can be understood that QCI is a scale value used to measure the packet forwarding behavior of a specific service data flow (such as packet loss rate, packet delay budget). It can be applied to both GBR and Non-GBR for specified access. The control bearer-level packet forwarding method defined in the node (such as scheduling weight, admission threshold, queue management threshold, link layer protocol configuration, etc.) can be pre-configured by the operator into the access network node.

S120: The MEC server sends QoS information to the OAM entity.

The QoS information may include the first QoS parameter of the UE and the UE identity of the UE. Optionally, the OAM entity may be an OAM entity corresponding to the base station that the UE accesses when using MEC local services.

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 that the UE accesses when using MEC local services.

S140: The base station receives the QoS information sent by the OAM entity, and determines whether the UE has accessed the network based on the UE identifier in the QoS information.

S150: When it is determined that the UE has entered the network, the base station generates RRC connection reconfiguration information based on the QoS information.

Optionally, in one embodiment, the base station can generate bearer modification request information according to the QoS information, and generate RRC connection reconfiguration information according to the bearer modification request information. As an example, 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. When the corresponding resource type is Non-GBR, the base station generates bearer modification request information based on the QoS information, and generates RRC connection reconfiguration information based on the bearer modification request information.

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

Among them, the RRC connection reconfiguration information can be used by the UE to update its air interface scheduling information according to the RRC connection reconfiguration information.

In the QoS control method of the embodiment of the present invention, the MEC server can obtain the first QoS parameter of the UE connected to it, and send the QoS information including the first QoS parameter and the UE identification to the OAM entity. It does not require the participation of the core network, and OAM The entity can send QoS information to the base station that the UE accesses, without sending QoS information to the entire network base station. When it is determined that the UE has entered the network, the base station can generate RRC connection reconfiguration information based on the QoS information and send it to the UE for air interface scheduling of the UE. Reconfiguration of information, so that when the UE uses MEC local services, only the QoS parameters of the base station where the UE is located can be updated, which is conducive to reasonable scheduling and utilization of wireless resources. It can also determine the UE's local MEC services based on the first QoS parameters. priority.

In one embodiment, in order to more accurately determine whether the UE has accessed the network, before determining whether the UE has accessed the network based on the UE identity in the QoS information, the following steps may also be included: when any UE accesses the base station, the base station may obtain any UE identity of the UE. This step is explained below with a specific example:

As shown in Figure 2, when the base station completes user registration or the UE switches in from other base stations, that is, when any UE accesses the base station, the base station can construct a Non-Access-Stratum (NAS) message, that is, an identification request. (IndentityRequest), here, the identification request indicates that the UE identification is IMSI, and then the identification process is carried out based on the identification request. The arbitrary UE returns its IMSI in the identification response (Indentity response), so that the UE identification of the arbitrary UE can be obtained, and Recorded in the context of any UE in the base station for subsequent use.

Furthermore, the UE identifier in the QoS information can be searched in the UE identifier of any UE. When the UE identifier in the QoS information is found in the UE identifier of any UE, it is determined that the UE has entered the network. When the UE identifier is not found in the UE identifier of any UE, When the UE identifier in the QoS information is found, it is determined that the UE is not connected to the network. In this way, whether the UE is connected to the network 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 following steps may also be included:

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 the RRC connection reconfiguration completion information to the base station.

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

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.

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 can be notified in a timely manner that the air interface scheduling information of the UE has been updated.

Taking the QoS update when the user logs in to the MEC server as an example, the QoS control method of the present invention will be explained with a specific embodiment. As shown in Figure 3, the QoS control method may include the following steps:

Step 1. To use MEC local services, the user needs to log in to the MEC server first. When the user services logs in, that is, when the UE logs in to the MEC server, the UE can send the IMSI to the MEC server, and the MEC server can associate the UE's IMSI with the UE's IP. Store, and later when the UE is doing business, the corresponding IMSI can be obtained through the UE's IP query. After the MEC server completes the user login, the MEC server can determine the preset QoS parameter corresponding to the IMSI among multiple preset QoS parameters according to the IMSI of the UE, and determine the corresponding preset QoS parameter as the first QoS parameter. Each The preset QoS parameters include QCI, ARP priority, preemption capability, and preemption capability.

Among them, the preset QoS parameters are preset, and the specific settings can be shown in Table 2:

Table 2

UE identity IMSI QCI ARP priority(1-15) Preemption ability Preempted ability UE1 9 10 Not preemptible Can be preempted UE2 6 6 Preemptible cannot be preempted UE3 7 7 Preemptible Can be preempted UE4 8 8 Not preemptible cannot be preempted

As an example, when the IMSI of the UE is UE1, the preset QoS parameters corresponding to the IMSI are QCI 9, ARP priority 10, preemption capability non-preemptible, and preempted capability capable of being preempted. Then determine 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 includes 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 can receive the QoS information sent by the MEC server and send the QoS information to the base station.

Step 4: The base station can receive the QoS information sent by the OAM entity, and check whether the UE is connected to the network according to the IMSI of the UE in the QoS information. If it is connected to the network, perform step 5. If it is not connected to the network, it will not be processed.

Step 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 so, the base station can generate modified bearer request information, that is, Modify BearerRequest information, based on the QoS information, and generate RRC connection reconfiguration information, that is, RRC ConnectionReconfiguration information, based on the modified bearer request information, and record the QoS information sent by the OAM entity. If not, it will not be processed.

Step 6: The base station can send RRC connection reconfiguration information to the UE.

Step 7: The UE can 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 completion information to the base station.

Step 8: The base station can receive the RRC Connection Reconfiguration Complete information sent by the UE, and determine that it is the Modify Bearer Request triggered by the OAM entity based on the recorded QoS information sent by the OAM entity. There is no need to report to the Mobility Management Entity. , MME) sends modification bearer response information, that is, Modify Bearer Response information, but sends Qos parameter response information to the OAM entity.

Step 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 the QoS parameter response information sent by the OAM entity.

This can ensure that when users log in to MEC local services, they can obtain the user's corresponding QoS parameters, and based on this, the user's priority in MEC local services can be effectively distinguished.

Taking dynamically updating QoS according to the service currently used by the user as an example, the QoS control method of the present invention will be explained with a specific embodiment. As shown in Figure 4, the QoS control method may include the following steps:

Step 11: The MEC server can determine the preset QoS parameter corresponding to the IMSI among multiple preset QoS parameters according to the IMSI of the UE, and can obtain the second QoS parameter of the service currently used by the UE based on the current service data of the UE, and based on The second QoS parameter and the corresponding preset QoS parameter determine the first QoS parameter.

Among them, the second QoS parameters of the service are planned in advance by the operator. The second QoS parameters can include QCI. The specific form can be as shown in Table 3:

table 3

business type QCI Business 1 5 Business 2 6 Business 3 7 Business 4 8 Business 5 9

As an example, combined with Table 2 and Table 3, when the IMSI of the UE is UE1 and the UE is using service 1, the default QoS parameters corresponding to the IMSI at this time are QCI 9, ARP priority 10, and preemption capability. It is non-preemptible, the preemption capability is preemptible, the second QoS parameter is QCI is 5, at this time, the first QoS parameter determined based on the second QoS parameter and the corresponding preset QoS parameter is QCI is 5, and the ARP priority is 10. The preemption capability is non-preemptible, and the preempted capability is preemptible.

Step 12: The MEC server may send QoS information to the OAM entity, where the QoS information includes 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 can receive the QoS information sent by the MEC server and send the QoS information to the base station.

Step 14: The base station can receive the QoS information sent by the OAM entity, and check whether the UE is connected to the network according to the IMSI of the UE in the QoS information. If it is connected to the network, step 15 is performed. If it is not connected to the network, it will not be processed.

Step 15: 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 so, the base station can generate bearer modification request information based on the QoS information, generate RRC connection reconfiguration information based on the bearer modification request information, and record the QoS information sent by the OAM entity. If not, it will not be processed.

Step 16: The base station may send RRC connection reconfiguration information to the UE.

Step 17: The UE can 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 the RRC connection reconfiguration completion information to the base station.

Step 18. The base station can receive the RRC connection reconfiguration completion information sent by the UE, and determine that it is the ModifyBearer Request triggered by the OAM entity based on the recorded QoS information sent by the OAM entity. There is no need to send the modify bearer response message to the MME, but to the OAM entity. Qos parameter response information.

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.

In this way, QoS-related parameters can be adjusted faster according to the user's corresponding QoS parameters and service QoS parameters, ensuring the efficiency of service air interface scheduling.

Based on the QoS control method of the embodiment of the present invention, the embodiment of the present invention also provides a QoS control device. The QoS control device is applied to the MEC server. As shown in Figure 5, the QoS control device 200 may include: an acquisition module 210, Send module 220.

Among them, the obtaining module 210 is used to obtain the first QoS parameter of the UE. The sending module 220 is configured to send QoS information to the OAM entity, where the QoS information includes the first QoS parameter of the UE and the UE identity of the UE, for the OAM entity to send the QoS information to the base station, and the base station determines according to the UE identity in the QoS information.
