In order to facilitate understanding of technical solutions of the embodiments of the present disclosure, a plurality of embodiments are listed in the embodiments of the present disclosure to clearly explain the technical solutions of the embodiments of the present disclosure. Of course, it can be understood by those skilled in the art that the embodiments provided in the present disclosure may be executed alone, or may be executed in combination with methods of other embodiments in the present disclosure, or may be executed in combination with some methods in other related arts; the disclosed embodiments are not limited thereto.

The embodiment of the disclosure provides a method for processing QoS (quality of service) grade. Fig. 2 is a flowchart illustrating a method for processing QoS class according to an exemplary embodiment, where the method is applied to a ue, as shown in fig. 2, and the method includes the following steps:

step S101, determining the expected QoS grade of the service to be transmitted of the user equipment;

step S102, sending grade information of the expected QoS grade to a base station, wherein the grade information is used for the base station to determine the QoS grade of the service to be transmitted.

In the embodiment of the present disclosure, the method is applied to a user device, and the user device may be, but is not limited to, a mobile phone, a wearable device, a vehicle-mounted terminal, an intelligent home terminal, and/or an intelligent office device.

Here, the base station may be an access device for accessing the user equipment to the network, and the base station may be various types of base stations. For example, a base station of a third generation mobile communication (3G) network, a base station of a fourth generation mobile communication (4G) network, a base station of a fifth generation mobile communication (5G) network, or a base station of any generation communication system.

The user equipment can determine the expected QoS (quality of service) grade of the service to be transmitted according to the requirement of the service to be transmitted on wireless network resources. And the user equipment sends the grade information of the expected QoS grade of the service to be transmitted to the base station, so that the base station determines the QoS grade of the service to be transmitted according to the received grade information.

It should be noted that, the level information of the QoS level determined by the base station and the level information of the desired QoS level determined by the user equipment may be the same level information or different level information; for example, the level information of the desired QoS level sent by the user equipment to the base station indicates that the required QoS level of the service to be transmitted is level 1, and the base station determines the QoS level of the service to be transmitted as level 2 (prior to level 1) according to the level information of the desired QoS level.

The QoS grade of the service to be transmitted is determined by the base station, the expected QoS grade sent by the user equipment is only used for providing a reference function in the process that the base station determines the QoS grade of the service to be transmitted, and the base station can determine the QoS grade by referring to the expected QoS grade of the service to be transmitted and the idle condition of network resources so as to meet the requirement of the wireless network resources of the service to be transmitted.

For example, the level information of the expected QoS level sent by the user equipment to the base station indicates that the QoS level required by the service to be transmitted is level 2, the base station determines the QoS level by referring to the expected QoS level of the service to be transmitted and the idle condition of the network resource, and if the current network resource is in the idle state, the base station may determine the QoS level of the service to be transmitted as level 2; if the current network resource is in the congestion state, the base station may determine the QoS level of the traffic to be transmitted as level 1 (lower than level 2).

It can be understood that the demands of different services on the wireless network resources are different, and the base station provides different service quality guarantees by determining different QoS levels for different services and allocating the wireless resources adapted to the QoS levels for the services. However, in practical applications, sometimes it is difficult for the base station to distinguish the specific service type of the service to be transmitted, that is, the requirement condition of the service to be transmitted on the wireless resource is uncertain, so that the base station can only allocate a general QoS class to different services to be transmitted when determining the QoS class of the service to be transmitted, which causes unreasonable scheduling of the wireless resource and low utilization rate of the wireless resource.

Therefore, in order to improve the rationality of wireless resource scheduling, the user equipment initiating the service transmission request determines the expected QoS class of the service to be transmitted, and sends the class information of the expected QoS class to the base station, so that after the base station receives the class information, the QoS class of the service to be transmitted can be determined according to the class information.

Optionally, the determining, in step S101, an expected quality of service QoS level of the service to be transmitted of the user equipment may include:

or,

In the embodiment of the present disclosure, when an application triggers data service transmission, user equipment may obtain service description information of a service to be transmitted, and determine an expected QoS level of the service to be transmitted according to the service description information of the service to be transmitted.

In some embodiments, the service description information may be used to indicate radio resource requirement information corresponding to the service to be transmitted. The service description information and the grade information of the expected QoS grade have a mapping relation, the grade information having the mapping relation with the service description information can be determined according to the service description information of the service to be transmitted, and the grade information is determined as the expected QoS grade of the service to be transmitted.

In other embodiments, the service description information includes one or more service attributes, where the service attributes describe characteristics of the service to be transmitted, for example, the content related to the service attributes includes one or more of the following items: the service type, the maximum delay allowed by the service, the average rate during service transmission, the minimum rate of service transmission, etc.

For example, the traffic types may include: MBB service and URLLC service; and the corresponding QoS levels of the MBB service and the URLLC service are different.

The user equipment can also acquire the type of the application program providing the service to be transmitted when the application program triggers data service transmission, and determine the expected QoS level of the service to be transmitted according to the type of the application program.

Here, different desired QoS levels may be allocated to the service to be transmitted provided by the application according to the type of the application.

Illustratively, the service data of the live broadcast application and the short message service of the short message application are different, and the sensitivity to delay is obviously different.

In some embodiments, the expected QoS level of the service to be transmitted may be determined according to the type of the application and a preset expected QoS level mapping table.

Here, the desired QoS class mapping table includes a correspondence between at least two desired QoS classes and types of the applications providing the service to be transmitted. The types of the application programs corresponding to different expected QoS levels are different;

it should be noted that, the correspondence between the desired QoS level in the desired QoS level mapping table and the application type may be set according to actual requirements, which is not limited in this disclosure.

The method comprises the steps that when data service transmission is triggered by an application program, user equipment obtains the type of the application program providing the service to be transmitted; and inquiring the expected QoS grade corresponding to the type of the application program of the service to be transmitted from a preset expected QoS grade mapping table.

Optionally, the service description information includes at least one of:

service type information of the service;

a transmission delay required for the service;

a maximum transmission rate required for the service;

the maximum packet loss rate of the service;

the throughput of the service;

the bandwidth required for the service.

In this embodiment of the present disclosure, the service type information may be a type parameter, where the type parameter is used to indicate a service type of the service to be transmitted, for example, a standardized definition service such as an internet of things service, a broadband service, or a low-latency ultra-reliable service; the type parameter and the service type can be preset with corresponding mapping relation.

And if the service description information comprises the service type information, the user equipment determines the specific service type of the service to be transmitted according to the acquired service type information of the service to be transmitted. Therefore, the demand condition of the service to be transmitted on the wireless resource can be predicted according to the specific service type of the service to be transmitted, and an expected QoS grade is set for the service to be transmitted.

In some embodiments, the desired QoS level includes: a first parameter; the first parameter is used for characterizing a threshold value corresponding to the expected QoS level;

it is understood that the first parameter is different for different desired QoS levels, i.e. the threshold value is different for different desired QoS levels. The parameter value of at least one item of description information contained in the service description information of the service to be transmitted can be compared with the first parameter of the QoS grade, and the expected QoS grade corresponding to the service to be transmitted is determined according to the comparison result.

Exemplarily, taking the service description information includes a transmission delay, where the transmission delay may be a maximum transmission delay that can be tolerated by the service; by comparing the maximum transmission delay that can be tolerated by the service with delay thresholds corresponding to multiple expected QoS levels, if the maximum transmission delay that can be tolerated by the service is less than or equal to a delay threshold corresponding to a certain expected QoS level, the expected QoS level can be determined as the expected QoS level of the service to be transmitted.

Further exemplarily, taking the service description information as including a bandwidth as an example, the bandwidth may be a network bandwidth requirement of the service; specifically, the bandwidth resource amounts corresponding to different expected QoS classes are different, a target class capable of meeting the network bandwidth requirement of the service to be transmitted is determined from the multiple expected QoS classes according to the network bandwidth requirement of the service to be transmitted and the bandwidth resource amounts corresponding to the multiple expected QoS classes, and the target class is determined as the expected QoS class of the service to be transmitted.

In other embodiments of the present disclosure, if the service description information of the service to be transmitted includes multiple items of description information, the desired QoS level of the service to be transmitted may be determined by performing weighted summation on parameter values of the multiple items of description information and according to a result of the weighted summation.

Optionally, the step S102 of sending the level information of the desired QoS level to the base station may include:

In the embodiment of the present disclosure, the user equipment may add the level information of the desired QoS level of the service to be transmitted in an RRC message, and send the RRC message to the base station, so that the base station obtains the level information from the RRC message, and determines the QoS level of the service to be transmitted according to the level information.

Here, the RRC message is a message initiated by a third layer, i.e., an RRC layer, of a Control plane between the ue and the base station, where the first layer is a physical layer and the second layer is a Medium Access Control (MAC) layer. The RRC layer allocates radio network resources and sends related signaling. The control information between the ue and the base station is mainly RRC messages. The RRC message carries all parameters required for establishing, modifying and releasing MAC layer and physical layer protocol entities, and also carries some signaling of a Non-Access Stratum (NAS) layer.

It should be noted that, in order to reduce the power consumption of the ue, the ue is usually in an idle state, and before performing service transmission (e.g. voice service or data service), an RRC connection needs to be established to enter a connected state from the idle state. The signaling related to the interaction between the user equipment and the base station in the RRC connection establishment process mainly includes: the user equipment may send an RRC Connection Request (RRC Connection Request) message to the base station, requesting establishment of an RRC Connection; a base station sends an RRC Connection Setup (RRC Connection Setup) message to user equipment, wherein the RRC Connection Setup message comprises allocated dedicated channel information; the user equipment sends an RRC Connection Setup Complete (RRC Connection Setup Complete) message to the base station, indicating that the RRC Connection Setup is successful. And if the user equipment is in a connected state, directly sending an RRC message carrying the grade information to a base station.

If the RRC message is: the RRC connection request message or the RRC connection establishment completion message indicates that the user equipment enters a connected state, and the user equipment may have higher probability of interacting with service data on the network side in the connected state, so the expected QoS grade is carried in the RRC connection establishment message, the user equipment does not need to be temporarily indicated to report the expected QoS grade when the subsequent network side schedules resources, and extra signaling is not needed to be introduced through the report of the RRC message in the related technology, so the RRC connection establishment completion message has the characteristic of strong compatibility with the prior art.

In the embodiment of the present disclosure, the user equipment may add a new level field in the RRC message, and encapsulate the level information of the desired QoS level of the service to be transmitted in the new level field, so that the RRC message can carry the level information of the desired QoS level of the service to be transmitted.

It should be noted that, the position of the level field in the RRC message may be arbitrarily set according to requirements, and the communication interaction between the user equipment and the base station is not affected by the position of the level field in the RRC message; for example, a level field may be inserted at the tail of the RRC message, or a level field may be inserted at the head of the RRC message; the present disclosure is not so limited.

After the user equipment sends the RRC message to the base station, the base station can conveniently acquire the grade information of the expected QoS grade of the service to be transmitted from the grade field according to the RRC message, so that the QoS grade of the service to be transmitted can be determined according to the grade information.

Optionally, the RRC message includes:

a service request message, or a tracking area update TAU request message;

the sending the grade information to the base station through a Radio Resource Control (RRC) message comprises:

In the embodiment of the present disclosure, the ue may send a Service Request (Service Request) message including the level information or a TAU Request message including the level information to the base station, so that the base station can determine the QoS level of the Service to be transmitted according to the level information of the desired QoS level of the Service to be transmitted.

It should be noted that the service request message and the TAU request message belong to NAS signaling, where the service request message is used to establish a radio bearer and an S1 bearer and transmit the signaling to be transmitted or the data to be transmitted when the signaling to be transmitted or the data to be transmitted exists in the user equipment or the base station.

When the user equipment needs to transmit service data to the base station, the user equipment can directly send a service request message carrying the expected QoS level of the service to be transmitted to the base station, so that the base station determines the QoS level for the service data requested to be transmitted by the service request message, the user equipment does not need to report the expected QoS level to the base station independently, additional signaling is not needed to be introduced, the interaction times between the user equipment and the base station are reduced, and network resources are saved.

The TAU request message is used for sending the TAU request message to the base station when the user equipment which is registered to the network enters a new tracking area or a periodic update timer is overtime, so as to report the position information of the user equipment to the base station and update the tracking area list.

When user equipment sends a TAU request message to a base station to report position information and update a tracking area list, the base station can determine the QoS grade of a service to be transmitted according to the grade information in the TAU request message by carrying the grade information of the expected QoS grade of the service to be transmitted in the TAU request message, and the user equipment does not need to be temporarily indicated to report the expected QoS grade; and no extra signaling is required to be introduced, so that the network resource can be saved, and the method is compatible with the prior art.

The embodiment of the disclosure provides a quality of service (QoS) grade processing method. Fig. 3 is a flowchart illustrating a method for processing QoS class according to an exemplary embodiment, where the method is applied to a base station, as shown in fig. 3, and the method includes the following steps:

step S201, receiving grade information of an expected QoS grade of a service to be transmitted, which is sent by user equipment;

step S202, according to the grade information, determining the QoS grade of the service to be transmitted.

In the embodiment of the present disclosure, the method is applied to a base station, where the base station may be an access device for a user equipment to access a network, and the base station may be various types of base stations. For example, a base station of a third generation mobile communication (3G) network, a base station of a fourth generation mobile communication (4G) network, a base station of a fifth generation mobile communication (5G) network, or a base station of any generation communication system.

The user equipment can be, but is not limited to, a mobile phone, a wearable device, a vehicle-mounted terminal, a smart home terminal and other user equipment.

The base station receives the grade information of the expected QoS grade of the service to be transmitted, which is sent by the user equipment, and determines the QoS grade of the service to be transmitted according to the grade information of the expected QoS grade of the service to be transmitted.

Here, the level information of the expected QoS level information of the service to be transmitted is used to indicate a demand situation of the service to be transmitted for wireless network resources.

It should be noted that, for different requirements of different service applications, the base station determines different QoS levels for different services, so as to provide different quality of service guarantees for the different services, such as bandwidth, packet loss rate, delay and delay jitter. Therefore, the comprehensive network capable of simultaneously carrying various services such as data, voice, video and the like is realized.

And the base station determines the requirement condition of the service to be transmitted on the wireless network resource according to the received grade information of the expected QoS grade of the service to be transmitted, so that the QoS grade adaptive to the requirement condition of the wireless network resource is determined for the service to be transmitted.

In some embodiments, the QoS level of the traffic to be transmitted, which is determined by the base station, is higher than or equal to the QoS level indicated by the level information.

In other embodiments, the QoS class of the traffic to be transmitted determined by the base station may also be lower than the QoS class indicated by the class information. For example, if the base station allocates resources according to the network state and the amount of available resources of the network and according to the desired QoS level provided by each UE, the capacity of the cell may be reduced, so that some UEs cannot access the cell; at this time, the base station may determine an actually used QoS level of the service without referring to a desired QoS level according to the network status and the network available resources.

That is, when the network condition and/or the network resource condition satisfy the preset condition, the base station will perform step S202.

It should be noted that, in the related art, a base station generally determines a QoS class of a service to be transmitted directly according to a service type of the service to be transmitted, but the base station can only distinguish whether the service to be transmitted is a call service or a network service, and for the network service, a specific service type of the service to be transmitted cannot be further distinguished, so that when the base station determines the QoS class of the service to be transmitted, the base station can only allocate a general QoS class to different types of network services to be transmitted, which results in unreasonable scheduling of wireless network resources and low resource utilization rate.

In contrast, in the embodiment of the present disclosure, in order to improve the rationality of wireless network resource allocation, the user equipment determines the expected QoS level of the service to be transmitted, and sends the level information of the expected QoS level of the service to be transmitted to the base station, so that the auxiliary base station can more accurately determine the QoS level of the service to be transmitted. The base station receives the grade information of the expected QoS grade of the service to be transmitted, and determines the QoS grade of the service to be transmitted according to the grade information, so that even if the base station cannot accurately distinguish the specific service type of the service to be transmitted, the QoS grade of the service to be transmitted can be accurately determined, more reasonable wireless network resources can be distributed for the service to be transmitted according to the QoS grade at the later stage, and the utilization rate of the network resources is improved.

Optionally, the receiving, in step S201, the level information of the desired quality of service QoS level of the service to be transmitted, which is sent by the user equipment, includes:

receiving a Radio Resource Control (RRC) message sent by the user equipment;

In the embodiment of the present disclosure, the RRC message includes level information of the QoS level of the service to be transmitted, and after receiving the RRC message sent by the user equipment, the base station obtains the level information from the RRC message by analyzing the RRC message, so as to determine the QoS level of the service to be transmitted at a later stage according to the level information of the desired QoS level of the service to be transmitted.

It should be noted that the RRC message is a signaling message required for establishing, re-establishing, maintaining, and releasing an RRC connection between the ue and the base station, and the RRC message carries all parameters required for establishing, modifying, and releasing a MAC layer and a physical layer protocol entity, and also carries some signaling of a Non-Access Stratum (NAS) layer.

In the embodiment of the present disclosure, after receiving an RRC message sent by a user equipment, a base station may analyze the RRC message to obtain the level field, and obtain level information in the level field; and determining the QoS grade of the service to be transmitted based on the grade information.

It should be noted that, the user equipment may add a new level field in the RRC message, and encapsulate the level information of the desired QoS level of the service to be transmitted in the new level field. And after the user equipment sends the RRC message to the base station, the base station can conveniently acquire the grade information of the expected QoS grade of the service to be transmitted from the grade field according to the RRC message.

Optionally, the RRC message includes:

a service request message, or a tracking area update TAU request message.

In the embodiment of the present disclosure, a base station may obtain, according to a received service request message or TAU request message, level information of an expected QoS level of a service to be transmitted, which is carried in the service request message or TAU request message, so as to determine, according to the level information, the QoS level of the service to be transmitted.

It should be noted that the Service Request (Service Request) message and the TAU Request message belong to NAS signaling, where the Service Request message is used to establish a radio bearer and an S1 bearer and transmit the signaling to be transmitted or the data to be transmitted when there is signaling to be transmitted or data to be transmitted in user equipment or a base station. The TAU request message is used for sending the TAU request message to the base station when the user equipment which is registered to the network enters a new tracking area or a periodic update timer is overtime, so as to report the position information of the user equipment to the base station and update the tracking area list.

Optionally, the method further includes:

In the embodiment of the present disclosure, a base station may determine, according to a QoS level of a service to be transmitted, radio resource configuration information of the service to be transmitted; and scheduling the wireless resource based on the wireless resource configuration information of the service to be transmitted.

The radio resource configuration information may include, but is not limited to: the access priority of the service to be transmitted, the network protocol stack architecture corresponding to the service to be transmitted, the allocated network wireless resources and the like,

in some embodiments, after determining the radio resource configuration parameter of the service to be transmitted, the base station may instruct the user equipment to perform configuration of radio resources by sending the radio resource configuration information to the user equipment.

It should be noted that the radio resource configuration information may be sent to the user equipment by the base station through system information, higher layer psychological or physical layer signaling. Wherein, the higher layer signaling may include: RRC signaling, media Access Control Element (MAC) signaling, and the like, but may be transmitted in other manners in actual applications.

The present disclosure also provides the following embodiments:

fig. 4 is a flow chart illustrating a method for processing QoS class according to an exemplary embodiment, where as shown in fig. 4, the method includes:

step S301, the user equipment determines the expected QoS grade of the service to be transmitted according to the type of the application program providing the service to be transmitted;

in this example, the user equipment may determine the expected QoS level of the service to be transmitted according to a preset expected QoS level mapping table and the type of the application program providing the service to be transmitted.

Here, the mapping table of the desired QoS level may be predefined and include a correspondence between the type of the application providing the service to be transmitted and the desired QoS level.

The service to be transmitted provided by the application program can be divided into different expected QoS levels according to the type of the application program. For example, the mapping table of the expected QoS levels may include 0 to 9 levels, and the expected QoS level of the service to be transmitted provided by the APP such as tremble, tencent video screen, etc. may be defined as class0, and the expected QoS level of the service to be transmitted provided by the APP such as network game such as Wangzheng game, etc. may be defined as class1.

In some embodiments, the desired QoS level for the traffic to be transmitted may be determined upon startup of an application providing the traffic to be transmitted.

When a user starts an APP, user equipment acquires the type of the APP and inquires an expected QoS level corresponding to the type in an expected QoS level mapping table.

Step S302, the user equipment sends RRC message containing the grade information of the expected QoS grade to the base station;

in this example, the RRC message may be a service request message or a TAU request message.

In some embodiments, the RRC message comprises: a rank field, wherein the rank field contains the rank information.

The user equipment sets a class field in the RRC message and fills class information of the desired QoS class in the class field. For example, a UE _ class field may be added to the RRC message, the class information of the desired QoS class of the service to be transmitted is filled in the UE _ class field, and the filled RRC message is sent to the base station.

Step S303, a base station receives an RRC message sent by user equipment, and obtains grade information of an expected QoS grade of the service to be transmitted from the RRC message;

in this example, after receiving an RRC message sent by a user equipment, a base station parses the RRC message to obtain a level field in the RRC message, and obtains level information of an expected QoS level of a service to be transmitted from the level field.

Step S304, the base station determines the QoS grade of the service to be transmitted according to the grade information;

in this example, the base station determines the QoS level of the service to be transmitted according to level information of an expected QoS level of the service to be transmitted, which is sent by the user equipment. Here, the QoS class of the traffic to be transmitted is greater than or equal to the desired QoS class.

It can be understood that, the user equipment assists the base station to determine the QoS class of the service to be transmitted by sending the class information of the desired QoS class of the service to be transmitted.

Step S305, the base station distributes wireless resources for the service to be transmitted according to the QoS grade.

In this example, the base station determines the radio resource configuration information of the service to be transmitted according to the QoS grade of the service to be transmitted; and scheduling the wireless resource based on the wireless resource configuration information of the service to be transmitted.

Exemplarily, the present example further provides a resource allocation method, as shown in fig. 5, and fig. 5 is a first flowchart of a resource allocation method according to an exemplary embodiment.

Step S401, an APP on User Equipment (UE) is started, and a UE side obtains an application type of the started APP;

step S402, the UE side judges the expected QoS grade of the service to be transmitted initiated by the APP;

step S403, the UE side reports the UE _ class to the network side through RRC;

step S404, the network side allocates a corresponding QoS grade for the service to be transmitted according to the UE _ class, and allocates resources corresponding to the QoS grade for the service to be transmitted.

In the embodiment of the disclosure, a UE side sends an RRC message to a network side by newly adding a UE _ class field in the RRC message and adding the grade information of the expected QoS grade of the service to be transmitted into the UE _ class field; and the network side acquires the UE _ class field from the RRC message and determines the QoS (quality of service) class of the service to be transmitted according to the class information in the UE _ class field, thereby scheduling different resources.

According to the resource allocation method provided by the example, the UE side can determine the expected QoS level of the service to be transmitted according to the APP type, the expected QoS level is sent to the network side, and the network side determines the QoS level of the service to be transmitted according to the expected QoS level, so that different resources are allocated for different APPs in a targeted manner, the use scene of a user is better fitted, the user experience is improved, and network resources are saved.

Next, the present example further provides a resource allocation method, as shown in fig. 6, and fig. 6 is a second flowchart of the resource allocation method according to an exemplary embodiment.

Step S501, an APP on User Equipment (UE) is started, and the UE side sends a service transmission request to a network side;

step S502, the network side distributes a universal QoS grade for the service to be transmitted;

step S503, the network side allocates resources for the service to be transmitted based on the general QoS grade.

However, the above method cannot allocate resources according to different APP types, which wastes network resources and is poor in user experience.

The embodiment of the disclosure also provides a device for processing the QoS grade.
