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 only a part of the embodiments of the present invention, and not all of the embodiments. 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.

To facilitate understanding of the embodiments of the present invention, a network architecture of the embodiments of the present invention is described below. Referring to fig. 1, fig. 1 is a schematic diagram of a network architecture according to an embodiment of the present invention. It is to be understood that the network architecture shown in fig. 1 is merely an example, and not a limitation. As shown in fig. 1, the network architecture of the embodiment of the present invention may include: a V2X Function Control unit 110 (V2X Control Function), a Home Subscriber Server 120 (HSS), a Mobility Management Entity 130 (MME), a base station 140, and a terminal 150. The terminal 150 may be a vehicle-mounted device (including a vehicle data recorder and a navigator) with a communication function, an intelligent street lamp, an intelligent traffic light, a camera device (such as an electronic eye and the like), a smart phone, a notebook, a tablet computer and the like. The V2X Control Function 110 is connected to the HSS 120 through a V4 interface, the HSS 120 is connected to the MME 130 through an S6a interface, the MME 130 is connected to the base station 140 through an S1 interface, and the base station 140 is connected to the UE a and the UE D through different LTE-Uu interfaces. The V2X function control unit 110 is connected to the UEs a to D through different V3 interfaces, respectively. UE A is connected with UE B and UE D through different PC5 interfaces respectively. UE B also connects to UE C through another PC5 interface.

In the network architecture shown in fig. 1, the HSS 120 stores information such as subscription of a terminal and operator policy. The HSS 120 may send the subscription and the operator policy of the terminal 150 to the V2X function control unit 110 or the MME 130, so that the V2X function control unit 110 or the MME 130 generates a first parameter according to the subscription and the operator policy of the terminal 150, and sends the first parameter to the base station 140, where the first parameter includes a QoS parameter that can be used by the terminal 150. After receiving the first parameter, the base station 140 provides a service for the terminal 150 according to the QoS parameter in the first parameter. The services provided by the base station 140 for the terminal 150 include establishing a PC5 radio bearer or providing radio resources, etc. The base station 140 further maps the first parameter to an eighth parameter, and transmits the eighth parameter to the terminal 150, wherein the eighth parameter is used for indicating a QoS parameter of a PC5 radio bearer of the terminal 150. The terminal 150 receives the eighth parameter sent by the base station 140, and sends the V2X message according to the eighth parameter, so as to ensure that the V2X message sent by the terminal 150 has QoS guarantee.

Since the first parameters generated by the V2X function control unit 110 or the MME 130 are different, the base station 140 can provide different levels of services for the terminal 150, which satisfies the requirement that the terminal 150 sends different types of V2X messages.

Referring to fig. 2, fig. 2 is a diagram illustrating a QoS generation method according to the present invention. As shown in fig. 2, the QoS generation according to the embodiment of the present invention includes the following steps:

210: the first network device generates a first parameter.

The first network device may be a V2X Control Function, MME, or other network element. The first parameter includes a QoS parameter that the terminal can use. The QoS parameter that can be used by the terminal is a QoS parameter that the MME or the V2X Control Function permits the terminal to send a message with the QoS guarantee, which may be a QoS parameter required to send a certain message, or a set of QoS parameters respectively required to send multiple messages. In a specific embodiment, the QoS parameter may be a PC5 based QoS parameter set, including PC5-QCI, ARP (Address Resolution Protocol), and the like. The PC5-QCI comprises a scheduling mode, a resource type (GBR or Non-GBR), PPPP (ProSe Per Packet Priority), packet Delay Budget and the like. In a specific embodiment, the first parameter may further include a third parameter, a fourth parameter, a fifth parameter, and so on. The third parameter is used for identifying the QoS level for controlling the forwarding processing of the PC5 wireless bearer level packet; the fourth parameter is used for indicating that the wireless resource is scheduled by the second network equipment or autonomously selected by the terminal; the fifth parameter is used to indicate the bit rate that the PC5 radio bearer can provide.

The first network equipment generates a first parameter according to the contract signing of the terminal and the operator strategy. The subscription and the operator policy of the terminal may be stored in another network element, for example, an HSS, and the first network device may obtain the subscription and the operator policy of the terminal from the other network element.

220: and the first network equipment sends the first parameter to the second network equipment so that the second network equipment provides service for the terminal according to the first parameter. Wherein, the second network device may be a base station, for example: macro base stations, micro cells, pico cells, home base stations, remote radio heads, relays, and the like.

In a specific embodiment, when the first network device is a mobility management entity, the first network device may send the first parameter directly to the second network device, or; when the first network device is a V2X control function entity, the first network device may send the first network device to the second network device through the home subscriber server and/or the mobility management entity. And after receiving the first parameter, the second network equipment provides service for the terminal according to the first parameter.

230: the second network device maps the first parameter to an eighth parameter, wherein the eighth parameter is used for indicating the QoS parameter of the terminal PC5 radio bearer. The PC5 radio bearer refers to a bearer between the terminal and the terminal, and is also called a PC5 bearer, a Sidelink, a radio bearer, a Sidelink bearer, or the like.

And the second network equipment maps the first parameter into an eighth parameter, and after mapping, the QoS parameter which can be used by the terminal in the first parameter is mapped into the QoS parameter indicating the wireless load of the terminal PC 5. Moreover, the mapped eighth parameter further includes information in a third parameter, a fourth parameter, and a fifth parameter of the first parameter. 240: and the second network equipment sends the eighth parameter to the terminal.

Optionally, the second network device sends a ninth parameter to the terminal, where the ninth parameter is used to instruct the terminal to send a radio resource of the V2X message. And the wireless resource indicated by the ninth parameter is used for sending a V2X message when the terminal autonomously schedules the resource.

250: and the terminal sends the V2X message according to the eighth parameter.

And after receiving the eighth parameter, the terminal sends the V2X message by using the service provided by the second network equipment according to the PC5-QCI in the eighth parameter. The V2X message is a message for carrying V2X information, and may be, for example, a V2V, V2P, V2I or V2N message, etc.

After the terminal receives the eighth parameter and before sending the V2X message, the terminal needs to determine whether the PC5-QCI corresponding to the V2X message belongs to the eighth parameter; if the parameter belongs to the eighth parameter, the terminal can send a V2X message; if not, the terminal cannot send the V2X message.

And if the terminal judges that the radio resources belong to the eighth parameter, the terminal obtains an indication that the radio resources are scheduled by the second network equipment or are selected by the terminal independently from the eighth parameter according to the PC5-QCI. Wherein, if the indication is that the second network device schedules the resource, the terminal requests the second network device for the wireless resource for transmitting the V2X message, or; when the terminal is instructed to schedule the resources, the terminal autonomously selects the radio resources for transmitting the V2X message, wherein the radio resources autonomously selected by the terminal for transmitting the V2X message may be the resources configured by the second network device to the terminal through signaling or the resources broadcasted in the system information, or may be the resources pre-configured to the terminal in advance.

In a specific embodiment, the terminal sends the second parameter to the first network device, where the second parameter is used to indicate a terminal type used by the terminal for the V2X service. And the first network equipment receives the second parameters sent by the terminal and generates the first parameters according to at least one of the subscription of the terminal, the operator strategy and the second parameters.

In a specific embodiment, the terminal sends a sixth parameter and/or a seventh parameter to the first network device, where the sixth parameter is used to indicate whether the terminal supports V2X capability, and the seventh parameter indicates a time length for which the terminal requests to use V2X service. And the first network equipment correspondingly receives the sixth parameter and/or the seventh parameter sent by the terminal to acquire information such as whether the terminal supports the V2X capability and/or the time length of the terminal requesting to use the V2X service, so as to authorize the terminal to use the V2X service and/or the time length of the terminal capable of using the V2X service. The duration that the terminal can use the V2X service may also be the valid time of the QoS parameter that can be used.

In a specific embodiment, after the first network device generates the first parameter, the first network device sends the first parameter to the terminal. And after receiving the first parameter sent by the first network equipment, the terminal stores the first parameter and provides the first parameter to the application layer so as to be used by the application layer for processing the V2X message. For example, the application layer determines whether the PC5-QCI corresponding to the V2X message to be sent belongs to the first parameter, if the PC5-QCI belongs to the first parameter, the application layer sends the V2X message to be sent to the lower layer or the transport layer for transmission, and if the PC5-QCI does not belong to the first parameter, the application layer cannot send the V2X message to the lower layer or the transport layer for transmission.

In a specific embodiment, the service provided by the second network device to the terminal may include: the second network equipment judges whether the PC5-QCI corresponding to the V2X message requested to be sent by the terminal belongs to the first parameter or not; if the first parameter belongs to, the second network equipment configures PC5 wireless bearer and/or allocates wireless resources for the terminal; if not, the second network device cannot configure the PC5 radio bearer and/or allocate radio resources for the terminal.

In a specific embodiment, the manner of configuring the PC5 radio bearer for the terminal by the second network device is as follows: and the second network equipment configures a first bearer for the terminal, generates a first bearer configuration and allocates a first bearer identifier for the first bearer, wherein the first bearer is used for the terminal to send the V2X message. After generating the first bearer configuration and allocating the first identifier, the second network device sends the first bearer identifier and the first bearer configuration to the terminal. And after the terminal receives the first bearer identification and the first bearer configuration distributed by the second network equipment, activating the first bearer.

In a specific embodiment, if the first bearer configured by the second network device for the terminal is not matched with the PC5-QCI corresponding to the V2X message that the terminal is ready to send, the second network device may further establish a second bearer matched with the PC5-QCI corresponding to the V2X message, or modify the first bearer to a bearer matched with the PC5-QCI corresponding to the V2X message that the terminal is ready to send.

Specifically, the terminal judges whether the PC5-QCI corresponding to the V2X message is matched with the PC5-QCI corresponding to the first bearer; if the matching is carried out, the terminal sends the V2X message through the first bearer; if not, the terminal judges whether the PC5-QCI corresponding to the V2X message belongs to the first parameter or not; if the first parameter belongs to the first parameter, the terminal sends a tenth parameter to the second network equipment to request the second network equipment to establish a second bearer or modify the first bearer into the second bearer, wherein the tenth parameter is used for indicating the PC5-QCI of the V2X message; if not, the terminal cannot send the V2X message.

In a specific embodiment, the manner for the second network device to establish the second bearer specifically includes: and the second network equipment generates a second bearer configuration for the terminal according to the tenth parameter and allocates a second bearer identifier for the second bearer, wherein the second bearer is used for the terminal to send the V2X message. After generating the second bearer configuration and allocating the second identifier, the second network device sends the second bearer identifier and the second bearer configuration to the terminal. And the terminal receives a second bearer identification and/or a second bearer configuration which are sent by the second network equipment and correspond to the second bearer, and activates the second bearer according to the second bearer configuration.

In a specific implementation manner, the second network device specifically uses the first bearer and the second bearer in the following manners: the second network device modifies the first bearer configuration to a second bearer configuration. And after the second bearer configuration is generated, the second network equipment configures the second bearer to the terminal. And the terminal receives a second bearer configuration corresponding to the second bearer sent by the second network equipment, and configures the second bearer according to the second bearer configuration.

In a specific embodiment, the manner for allocating the radio resource to the terminal by the second network device is specifically as follows: and sending a request for allocating the wireless resource to the second network equipment by the terminal, and correspondingly, receiving the request for allocating the wireless resource by the terminal by the second network equipment, wherein the request for allocating the wireless resource comprises the second parameter, the moving speed of the terminal, the position of the terminal, the identifier of the used wireless bearer and the like. Or, the request for allocating the radio resource includes the second parameter, the moving speed of the terminal, the location of the terminal, and the PC5-QCI corresponding to the V2X message that the terminal is ready to send, and so on. The moving speed of the terminal is used for the base station to determine the processing modes of the physical layer modulation, coding and the like of the message.

Optionally, the terminal sends a sixth parameter and/or a seventh parameter to the first network device, where the sixth parameter is used to indicate whether the terminal supports the V2X capability, and the seventh parameter indicates a time length for the terminal to request to use the V2X service. And the first network device correspondingly receives the sixth parameter and/or the seventh parameter sent by the terminal to acquire information such as whether the terminal supports the V2X capability and/or the time length of the terminal requesting to use the V2X service, so as to authorize the terminal to use the V2X service and/or the time length of the terminal capable of using the V2X service. The duration that the terminal can use the V2X service may also be the valid time of the QoS parameter that can be used.

2. And the first network equipment generates a first parameter according to at least one of the subscription of the terminal, the operator strategy and the second parameter. The first parameter includes a QoS parameter that the terminal can use. The QoS parameter that can be used by the terminal is a QoS parameter that the MME or the V2X Control Function permits the terminal to send a message with the QoS guarantee, which may be a QoS parameter required to send a certain message, or a set of QoS parameters respectively required to send multiple messages

3. After generating the first parameter, the first network device sends the first parameter to a second network device, so that the second network device provides a service for the terminal according to the first parameter.

Optionally, the second network device sends the first bearer identifier and the first bearer configuration to the terminal.

6. And the terminal receives the eighth parameter and stores the eighth parameter for use when sending the V2X message.

And after receiving the first parameter sent by the first network equipment, the terminal stores the first parameter and provides the first parameter to an application layer so that the application layer can process the V2X message. For example, the application layer determines whether the PC5-QCI corresponding to the V2X message to be sent belongs to the first parameter, and if the PC5-QCI belongs to the first parameter, the application layer sends the V2X message to be sent to a lower layer or a transport layer for transmission, and if the PC5-QCI does not belong to the first parameter, the application layer cannot send the V2X message to the lower layer or the transport layer for transmission.

Optionally, the terminal receives the ninth parameter and stores the ninth parameter, for use when sending the V2X message of the autonomous scheduling resource.

And after receiving the V2X message sent by the application layer, the terminal sends the V2X message by using the service provided by the second network equipment according to the PC5-QCI in the eighth parameter. The V2X message is a message for carrying V2X information, and may be, for example, a V2V, V2P, V2I or V2N message, etc.

After the terminal receives the eighth parameter and before sending the V2X message, the terminal needs to determine whether the PC5-QCI corresponding to the V2X message belongs to the eighth parameter; if the parameter belongs to the eighth parameter, the terminal can send the V2X message; and if the parameter does not belong to the eighth parameter, the terminal cannot send the V2X message.

And if the terminal judges that the terminal belongs to the eighth parameter, the terminal obtains an instruction of scheduling the wireless resource by the second network equipment or autonomously selecting the wireless resource by the terminal from the eighth parameter according to the PC5-QCI. Wherein, if the indication is that the second network device schedules resources, the terminal requests the second network device for radio resources for transmitting the V2X message, or; when the terminal is instructed to schedule resources, the terminal autonomously selects a radio resource for transmitting the V2X message, where the radio resource autonomously selected by the terminal for transmitting the V2X message may be a resource configured by the second network device to the terminal through signaling or a resource broadcasted in system information, or may be a resource pre-allocated to the terminal in advance.
