Description

Method for determining QoS parameter of direct communication interface and related equipment
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method for determining QoS parameters of a direct communication interface and a related device.
Background
Vehicle-To-Everything (V2X) networking is that vehicles and the outside world are interconnected in a hundred percent, which is the basic and key technology of future intelligent automobiles, automatic driving and intelligent transportation systems, wherein V2X mainly comprises four aspects, namely: vehicle-To-internet (V2N), vehicle-To-Vehicle (V2V), vehicle-To-Infrastructure (V2I), and Vehicle-To-Pedestrian (V2P).
At present, enhanced Vehicle-to-anything (eV 2X) communication is an Evolution of V2X communication, and on the basis of Long Term Evolution (LTE) based network V2X Vehicle-to-Vehicle communication, V2X communication is further realized by an LTE/5G technology, so that V2X can meet the demand of intelligent traffic more flexibly, safely and reliably. Meanwhile, in order to improve network transmission efficiency and reduce power consumption of a terminal (User Equipment, UE) in an eV2X service, a direct communication interface is accessed between the terminal and the terminal, for example: a PC5 interface.
In an eV2X system, the performance requirement of an eV2X Service may define a Quality of Service (QoS) parameter characterization of a direct communication interface. For the existing QoS parameter configuration method on the direct communication interface, the network side may configure the QoS parameter on the direct communication interface as a terminal authorization parameter to the terminal, and the QoS parameter of the direct communication interface needs to be negotiated when a one-to-one communication link is established between the terminal and the terminal. However, the QoS parameter model associated with QoS flow on the direct communication interface is still defined, and the negotiation of the QoS parameter of the direct communication interface between the terminal and the terminal needs to be implemented based on the specific QoS parameter model of the direct communication interface. Further, what criteria are needed for negotiation of QoS parameters of a direct communication interface between the terminal and the terminal, or how the terminal adjusts the QoS parameters of the direct communication interface after the negotiation of the QoS parameters of the direct communication interface between the terminal and the terminal is completed and the terminal receives an indication of an application layer or a link quality report of an access layer. The above problems not only affect the establishment process of one-to-one communication between terminals, but also affect the service continuity, further affecting the user experience.
It can be seen that, in the eV2X system, a QoS parameter model associated with a QoS flow on a direct communication interface is not defined, which affects a process of establishing one-to-one communication between terminals, thereby causing a problem of poor service continuity.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a method for determining a Quality of Service (QoS) parameter of a direct communication interface according to an embodiment of the present invention, applied to a first terminal, as shown in fig. 1, including the following steps:
step 101, determining a first direct communication interface QoS parameter of a QoS flow (QoS flow) from a first set of direct communication interface QoS parameters, wherein the QoS flow is a QoS flow transmitted between a first terminal and a second terminal, and the first terminal is configured with a first set of direct communication interface QoS parameters associated with the QoS flow and comprising different QoS parameters.
Wherein the second terminal may be configured with a second set of direct communication interface QoS parameters associated with the QoS flow and comprising different QoS parameters; and the first QoS parameter may be included within both the first set of direct communication interface QoS parameters and the second set of direct communication interface QoS parameters.
Here, the first terminal may determine the first QoS parameter of the QoS flow by configuring a first direct communication interface QoS parameter set associated with the QoS flow and a second direct communication interface QoS parameter set associated (or mapped) with the QoS flow, which is configured by the second terminal, so as to implement definition of a QoS parameter model associated with the QoS flow on the direct communication interface, and may satisfy that the first terminal establishes a one-to-one communication connection in the same enhanced Vehicle-to-anything (eV 2X) service and between multiple different second terminals, satisfy service continuity, and enhance user experience.
It should be noted that the eV2X system is a V2X vehicle networking system that performs communication based on a Long Term Evolution (LTE) Network or a 5G Network (5G Network), and V2X mainly includes four aspects, that is: the Vehicle-To-internet (V2N), the Vehicle-To-Vehicle (V2V), the Vehicle-To-Infrastructure (V2I), and the Vehicle-To-Pedestrian (V2P) are connected To the Vehicle-To-Infrastructure, so that the first terminal may be a Vehicle-mounted terminal in an eV2X system, and the second terminal may be another Vehicle-mounted terminal in the eV2X system, an Infrastructure terminal, or a terminal carried by a Pedestrian.
In this embodiment of the present invention, the first direct communication interface QoS parameter set and the second direct communication interface QoS parameter set both include different QoS parameters, that is, the first direct communication interface QoS parameter set and the second direct communication interface QoS parameter set both include at least two QoS parameters, and the number of QoS parameters in the first direct communication interface QoS parameter set and the number of QoS parameters in the second direct communication interface QoS parameter set may be the same or different, which is not limited herein.
It should be noted that the direct communication interface QoS flow (for example, the PC5QoS flow) is a QoS flow associated with eV2X traffic currently performed by the first terminal and the second terminal, and the first direct communication interface QoS parameter set and the second direct communication interface QoS parameter set are both mapped to the QoS. Of course, for other eV2X traffic that the first terminal is in communication with other terminals, the first terminal is also configured with a set of direct communication interface QoS parameters for the QoS flows associated with that other eV2X traffic, i.e. for different eV2X traffic, a different set of direct communication interface QoS parameters for the QoS flows associated with different eV2X traffic is configured in the first terminal. Similarly, the second terminal is also configured with different sets of Qos parameters of the direct communication interface of Qos flows associated with different eV2X services, which is not described herein again.
In addition, the first set of direct communication QoS parameters and the second set of direct communication QoS parameters have an association relationship (or called a mapping relationship) with the direct communication interface QoS flow and include at least two QoS parameters. The QoS parameters are parameters characterizing performance requirements of current eV2X services of the first terminal and the second terminal, and the QoS parameters are combinations including a 5G QoS identifier (5G QoS identifier,5 qi) value (value), a Guaranteed Flow Bit Rate (GFBR), a Maximum Flow Bit Rate (MFBR), an average window, and an Aggregate Maximum Bit Rate (AMBR) (e.g., UE-PC 5-AMBR).
For example: the QoS parameter set list 1 shown in table 1 below may be configured in the first terminal or the second terminal, and as shown in table 1, the QoS flow identifier (i.e., QFI # XX) is used to identify a mapping relationship between the QoS flow and a direct communication interface QoS parameter set, the direct communication interface QoS parameter set includes 3 QoS parameters, and each QoS parameter includes parameters such as a 5QI value, a guaranteed flow bit rate value, a maximum flow bit rate value, and an aggregate maximum bit rate.

In this embodiment of the present invention, the configuring of the first direct communication interface QoS parameter set in the first terminal may be configured through pre-configuration or network side device configuration, and optionally, before step 201, the method includes: pre-configuring a first direct communication interface QoS parameter set; or receiving first configuration information sent by the network side equipment, wherein the first configuration information is used for mapping a first direct communication interface QoS parameter set for the QoS stream, so that the mode of configuring the first direct communication interface QoS parameter set in the first terminal is flexible.
When the first direct communication interface QoS parameter set is preconfigured in the first terminal, the first direct communication interface QoS parameter set may be directly written into a Subscriber Identity Module (SIM) of the first terminal, and the configuration information is easily changed in a simple manner.
In addition, the network side device may also implement the configuration of the mapping relationship between the QoS flow and the first direct communication QoS parameter set and the configuration of the first direct communication QoS parameter set by sending the first configuration information to the first terminal, and configure the mapping relationship as the authorization parameter of the first terminal to the first terminal.
It should be noted that the network side device may be a small station, such as a Low Power Node (LPN) pico, a femto, or the network side device may be an Access Point (AP); the base station may also be a network node formed by a Central Unit (CU) and a plurality of Transmission Reception Points (TRPs) managed and controlled by the CU, and the specific type of the network side device is not limited in the embodiment of the present invention.
Of course, the second direct communication interface QoS parameter set may be configured in the second terminal, and may be configured by pre-configuration or network side device configuration, specifically, the second terminal may pre-configure or receive second configuration information sent by the network side device, where the second configuration information is used to map the second direct communication interface QoS parameter set for the QoS flow, and details are not described here.
In this embodiment of the present invention, the first terminal determines the first QoS parameter from the first set of QoS parameters of the direct communication interface, where the first terminal and the second terminal may determine, through negotiation, one common QoS parameter in the first set of QoS parameters of the direct communication interface and the second set of QoS parameters of the direct communication interface as the first QoS parameter.
The first terminal and the second terminal determine a common QoS parameter as the first QoS parameter in the first direct communication interface QoS parameter set and the second direct communication interface QoS parameter set through negotiation, where the first terminal may send a request message to the second terminal, the second terminal sends a response message carrying the second direct communication interface QoS parameter set to the first terminal in response to the request message, and the first terminal determines the common QoS parameter in the first direct communication interface QoS parameter set and the second direct communication interface QoS parameter set according to the response message and selects one common QoS parameter as the first QoS parameter.
Or, optionally, the determining, by the first terminal, the first QoS parameter from the first set of QoS parameters of the direct communication interface includes:
sending a direct communication request message carrying a first direct communication interface QoS parameter set to a second terminal;
receiving a direct communication reply message which is sent by a second terminal and carries a third direct communication interface QoS parameter set;
a first QoS parameter for the QoS flow is determined in a third set of direct communication interface QoS parameters.
Wherein the third direct communication interface QoS parameter set may comprise an intersection or a subset of an intersection of the first direct communication interface QoS parameter set and the second direct communication interface QoS parameter set.
Here, the first terminal and the second terminal may negotiate to determine an intersection or a subset of the intersection of the first set of direct communication interface QoS parameters and the second set of direct communication interface QoS parameters (i.e. a third set of direct communication interface QoS parameters), so that the first terminal determines an appropriate first QoS parameter in the third set of direct communication interface QoS parameters, thereby further improving the continuity of the traffic.
In addition, the third direct communication interface QoS parameter set may include only one QoS parameter, and then the first QoS parameter is the one QoS parameter.
For example: the first terminal may be configured with a QoS parameter set list 1 as shown in table 1, that is, the first direct communication interface QoS parameter set is a direct communication interface QoS parameter set of the QoS parameter set list 1; if the second terminal is configured with the QoS parameter set list 2 as shown in table 2 below, the following is shown:
table 2 QoS parameter set list 2
Figure BDA0001958546220000091
Then, the third QoS parameter set determined after the first terminal negotiates with the second terminal includes a QoS parameter 1, which is: 5QI value = x1; GFBR = y1; MFBR = z1; UE-PC5-AMBR #1 and the first QoS parameter determined by the first terminal is this QoS parameter 1.
Of course, the third QoS parameter set of the direct communication interface may also include a plurality of QoS parameters, for example: the first terminal may be configured with the QoS parameter set list 1 as shown in table 1 above; if the second terminal is configured with the QoS parameter set list 3 as shown in table 3 below, the following is shown:
table 3 QoS parameter set list 3
Figure BDA0001958546220000092
Then, the third set of direct communication interface QoS parameters determined after the first terminal negotiates with the second terminal may include QoS parameters 1 (i.e., 5QI value = x1 gfbr = y1 mfbr = z1 ue-PC5-AMBR # 1) and QoS parameters 2 (i.e., 5QI value = x2 gfbr = y 2.
In the case that the third direct communication interface QoS parameter set includes a plurality of QoS parameters, the determining the first QoS parameter of the QoS flow in the third direct communication interface QoS parameter set may be randomly selecting one QoS parameter as the first QoS parameter in the third direct communication interface QoS parameter set; alternatively, the second terminal may sort the QoS parameter sets in the third direct communication interface QoS parameter set, the first terminal may sort the QoS parameter sets in the third direct communication interface QoS parameter set, and select the QoS parameter at the first position or the last position in the sorting as the first QoS parameter, and so on.
Since there are different QoS level classes (e.g., automation levels) in eV2X traffic for some eV2X traffic. For example, the TS22.186 has five levels of automation divided for some eV2X traffic:
(0) No Automation (No Automation);
(1) Driver Assistance (Driver Assistance);
(2) Partial Automation (Partial Automation);
(3) Conditional Automation (Conditional Automation);
(4) High level Automation (High Automation);
(5) Fully automated (Full Automation).
To be able to meet the above type of eV2X service requirements, the above type of eV2X service also illustrates the need to design multi-level QoS parameters to meet different types of automation requirements. Specifically, the QoS parameters in the first direct communication interface QoS parameter set and the second direct communication interface QoS parameter set may further include a priority parameter to meet the requirement of the eV2X service multiple automation levels of the types.
For example: at a certain eV2X service three levels of QoS levels are divided: in the case of a high QoS level (highest QoS level), a medium QoS level (medium QoS level), and a low QoS level (lowest QoS level), the first terminal or the second terminal may be configured with a QoS parameter set list 4 as shown in table 4 below, where 3 QoS parameters in the direct communication interface QoS parameter set shown in table 4 have different levels compared to the direct communication interface QoS parameter set in table 1, that is, each QoS parameter further includes a priority parameter, for example, a priority parameter including Rank1 (highest QoS level) indicates a QoS parameter with the highest priority.
Table 4 QoS parameter set list 4
Figure BDA0001958546220000101
In a case that the QoS parameters in the first direct communication interface QoS parameter set and the second direct communication interface QoS parameter set may further include priority parameters, since the third direct communication interface QoS parameter set is an intersection of the first direct communication interface QoS parameter set and the second direct communication interface QoS parameter set, optionally, the QoS parameters in the third direct communication interface QoS parameter set include priority parameters.
Under the condition that the QoS parameters in the third direct communication interface QoS parameter set include the priority parameter, optionally, the first QoS parameter is a QoS parameter with the highest priority in the third direct communication interface QoS parameter set, so that a requirement of multiple automation levels of the eV2X service can be met, and service continuity is further improved.
Specifically, in a case where the third direct communication interface QoS parameter set includes at least two QoS parameters, the first terminal may compare priorities of the at least two QoS parameters according to priority parameters of the at least two QoS parameters, and determine a QoS parameter with a highest priority in the third direct communication interface QoS parameter set as the first QoS parameter.
For example: assuming that the third direct communication interface QoS parameter set includes QoS parameters 3 and 4, and the QoS parameter 3 is a QoS parameter including Rank2 (medium QoS level) in the table 4, and the QoS parameter 4 is a QoS parameter including Rank3 (lowest QoS level) in the table 4, since the priority of the QoS parameter 3 is higher than that of the QoS parameter 4, the first terminal selects the QoS parameter 3 as the first QoS parameter.
In this embodiment of the present invention, after the first terminal determines the first QoS parameter of the direct communication interface QoS flow, the first terminal may apply the first QoS parameter to the direct communication interface QoS flow, so as to establish a one-to-one communication link between the first terminal and the second terminal.
In the process of establishing a one-to-one communication link between the first terminal and the second terminal for communication, in some special scenarios, the QoS parameters of the QoS flow of the direct communication interface of the current eV2X service may be affected, and therefore the QoS parameters of the QoS flow of the direct communication interface between the first terminal and the second terminal need to be dynamically adjusted.
Optionally, the third direct communication interface QoS parameter set includes at least two QoS parameters; after determining the first QoS parameter for the QoS flow from the third set of direct communication interface QoS parameters, comprising: the QoS parameters of the QoS flow are changed into the second QoS parameters in the third direct communication interface QoS parameter set, so that the QoS parameters of the direct communication interface QoS flow between the first terminal and the second terminal can be dynamically adjusted, and the continuity of the service is improved.
The second QoS parameter may be any QoS parameter except the first QoS parameter in the third direct communication interface QoS parameter set, so that after the QoS parameter of the direct communication interface QoS flow between the first terminal and the second terminal is adjusted from the first QoS parameter to the second QoS parameter, the service continuity can be improved.
In addition, the above changing the QoS parameter of the QoS flow to the second QoS parameter occurs when the QoS parameter of the QoS flow between the first terminal and the second terminal is affected, and optionally, the changing the QoS parameter of the QoS flow to the second QoS parameter in the third direct communication interface QoS parameter set includes:
changing the QoS parameter of the QoS flow into a second QoS parameter in a third direct communication interface QoS parameter set under the condition that the current QoS level grade of the application layer is changed; or
And under the condition that the link quality of the current direct communication interface is detected to be changed, the QoS parameters of the QoS flows are changed into the second QoS parameters in the third direct communication interface QoS parameter set.
In the process that the first terminal establishes a one-to-one communication link with the second terminal for communication, if different QoS levels exist in the current eV2X service, the first terminal may detect whether the current QoS level of the application layer is changed, and change the QoS parameter of the QoS flow to the second QoS parameter in time when detecting that the current QoS level of the application layer is changed (for example, the current automation level of the application layer is changed).
Or, the first terminal may further detect whether the quality of the current direct communication interface link changes, and change the QoS parameter of the QoS flow to the second QoS parameter in time when the quality of the current direct communication interface link changes.
In addition, the priority of the second QoS parameter may be associated with the changed link quality of the direct communication interface, so that the changed QoS parameter is more suitable, and the continuity of the service is further improved.
For example: the first terminal selects a suitable QoS parameter from the third direct communication interface QoS parameter set as the QoS parameter of the current QoS flow (i.e., the second QoS parameter), and the determination criterion may be:
if the application layer reduces the automation level or the access layer reports that the link quality of the current direct communication interface is poor, the terminal selects the QoS parameter with lower priority in the QoS parameter set of the third direct communication interface;
if the application layer promotes the automation level or the access layer reports that the link quality of the current direct communication interface is better, the terminal selects the QoS parameter with higher priority in the third direct communication interface QoS parameter set.
In the embodiment of the present invention, a first QoS parameter of a QoS flow of a direct communication interface is determined from a first set of QoS parameters of the direct communication interface, where the QoS flow is a QoS flow transmitted between a first terminal and a second terminal, and the first terminal is configured with a first set of QoS parameters of the direct communication interface associated with the QoS flow and including different QoS parameters. Therefore, the definition of a QoS parameter model associated with QoS flow on a direct communication interface can be realized, and the requirement that a first terminal establishes one-to-one communication connection in an eV2X service and among a plurality of different second terminals is met, so that the service continuity is met, and the user experience is improved.
Please refer to fig. 2, which is a flowchart illustrating another method for determining QoS parameters of a direct communication interface according to an embodiment of the present invention, applied to a second terminal, as shown in fig. 2, the method for determining QoS parameters of a direct communication interface includes the following steps:
step 201, receiving a direct communication request message carrying a first direct communication interface QoS parameter set sent by a first terminal;
step 202, based on the direct communication request message, sending a direct communication reply message carrying a third direct communication interface QoS parameter set to the first terminal, so that the first terminal determines a first QoS parameter of the QoS flow in the third direct communication interface QoS parameter set;
wherein the second terminal is configured with a second set of direct communication interface QoS parameters associated with the QoS flow and comprising different direct communication interface QoS parameters; the third direct communication interface QoS parameter set comprises an intersection or a subset of an intersection of the first direct communication interface QoS parameter set and the second direct communication interface QoS parameter set.
In this embodiment of the present invention, a first terminal may determine a first QoS parameter of a QoS flow from a third set of direct communication interface QoS parameters, where the first terminal may be configured with a first set of direct communication interface QoS parameters associated with the direct communication interface QoS flow and including different direct communication interface QoS parameters; the first QoS parameter is included in a first set of direct communication interface QoS parameters and a second set of direct communication interface QoS parameters.
