Description

Method and device for processing car network business

Technical field

The present application relates to, but is not limited to, the field of communications, and relates to a method and apparatus for processing a car networking service.

Background technique

With the rapid development of economy and society, China's automobile ownership has grown rapidly, and road traffic accidents have occurred frequently. It has become one of the important factors affecting China's public security in recent years. Road traffic safety has become a basic problem affecting social harmony and improving people's livelihood. one. China urgently needs to improve traffic safety from various aspects such as technology, policy, education, etc. Among them, improving vehicle safety design is an important part of it.

The technologies to improve vehicle safety are mainly divided into passive safety technology and active safety technology. Passive safety technology is used to protect people inside and outside the vehicle after accidents. Active safety technology is used to prevent and reduce accidents in vehicles and avoid injuries. Active safety technology is the focus of modern vehicle safety technology development. And trends.

The communication-based collision warning system realizes real-time information interaction between the vehicle, the vehicle and the roadside infrastructure by using advanced wireless communication technology and a new generation of information processing technology, and informs each other of the current state (including the position and speed of the vehicle). Acceleration, driving route) and learned road environment information, collaboratively aware of road hazard conditions, timely providing a variety of collision warning information to prevent road traffic safety accidents, and become a new way for countries to solve road traffic safety problems. .

1 is a schematic diagram of transmitting traffic and scheduling information to a vehicle through a network information platform in the related art, and FIG. 2 is a schematic structural diagram of a LTE (Long Term Evolution) vehicle network in the related art. Referring to FIG. 1 and FIG. 2, Vehicle to Everything (V2X) refers to providing vehicle information through sensors, vehicle terminals and electronic tags mounted on vehicles, and adopting various communication technologies to realize vehicles and vehicles (Vehicle) To Vehicle (V2V), Vehicle to Personal (V2P), Vehicle to Infrastructure (V2I), and information on the information network platform Effective use of extraction, sharing, etc., effective control and provision of comprehensive services for vehicles.

In recent years, with the development of new mobile communication technologies, the use of LTE technology to solve the research based on vehicle networking communication applications has emerged internationally. The Road Side Unit (RSU) can receive vehicle requests, ensure that the vehicle accesses the Internet (Internet), and has the function of a gateway; in addition, it also has the functions of data calculation, storage, and forwarding.

The main features of the communication between Vehicle and Road Side Unit (V2R, also known as V2I) include:

(1) When the RSU is broadcast, the broadcast information is only sent to all vehicles within its coverage;

(2) Single-hop transmission between the RSU and the vehicle to prevent adverse effects such as low packet transmission success rate and low network throughput caused by multi-hop;

(3) The RSU can quickly receive detected vehicles, traffic lights, and some road condition information, and process, reorder, and select the information before sending it to the vehicle.

The above three aspects ensure that when the vehicle passes through the RSU, the connection with the RSU ensures that the vehicle can access the Internet reliably or in real time or download data stored by the RSU.

In order to achieve V2V communication, each vehicle supporting V2V communication needs to obtain the resources required for communication (such as communication frequency and time slot and other physical resources). When V2V communication adopts 3GPP (Third Generation Partnership Project, third generation partner) When planning the D2D (Device-to-Device) technology defined by the scheme, the resources required for V2V communication can be obtained in a competitive manner, such as: first use first, but this method may be more in the vehicle. Under the region, resource congestion and collisions occur. For example, there is a pre-allocated resource block, but multiple vehicles use the same resources (such as the same frequency resources and time slot resources), which will make these vehicles unable to use the resources, so that the information of these vehicles can not be used. Send it out. Therefore, in V2V communication, if the vehicle obtains the resources in the resource pool in a competitive manner, it is easy to cause a collision and the vehicle information cannot be transmitted in time.

It can be seen that when an on-board unit (OBU, On Board Unit) has an emergency service notification to be sent, if multiple OBUs are used to transmit emergency services in a competitive manner, resource conflicts may occur, resulting in failure of emergency service transmission. In view of the above problems in the related art, an effective solution has not yet been proposed.

The embodiments of the present invention are exemplified below in conjunction with the optional implementation of the present invention.

The optional embodiment provides a method for processing a service notification, the method comprising: a roadside unit (RSU) transmitting resource allocation information of a high priority car networking (V2X) service notification, and an onboard unit (OBU) receiving the information. When it is determined that a high-priority V2X service needs to be sent, the OBU selects a corresponding resource to send a high-priority V2X service notification according to the indication of the RSU.

The delay of the OBU to send the high-priority V2X service notification is shortened, the collision probability of the high-priority V2X service notification is reduced, and the probability of sending the high-priority V2X service notification is improved.

FIG. 5 is a flowchart of a method for processing a service notification according to an alternative embodiment of the present invention. As shown in FIG. 5, the steps of the method include:

In step S501, the RSU allocates a resource pool for the high priority car network (V2X) service notification.

The RSU is a base station (eNB) or a stationary UE (User Equipment) or a dedicated RSU (such as an access point (AP) in the communication protocol 802.11P); the high priority V2X service is a predefined service. Or the business specified by the RSU.

The service notification refers to the information indicating the high priority V2X service, not the high priority V2X service itself; the content of the high priority V2X service notification is limited, generally indicated by one or more bits; the high priority V2X service The notification includes at least one of the following: a high priority V2X service identifier or a service index.

If the D2D technology is used to implement the V2X service notification, the OBU can use the D2D discovery or the D2D communication to implement the V2X service notification transmission. For the high-priority V2X service, considering the limited content of the service notification, the D2D discovery or the D2D communication control channel can be used. Notification information.

V2X includes: V2V, V2I, V2P.

In addition, the resource pool includes: a sending resource pool and a receiving resource pool, wherein the sending resource pool is a resource pool used for high-priority V2X service notification, that is, independent of the D2D resource pool in the related art; High-priority resource pool, which is related to the resource pool of common V2X service notifications. Independent of each other, the OBU monitors different receiving resource pools. The resource pool may be indicated by one or more of the following: time-frequency location/index, cyclic prefix (CP) length, period, modulation and coding scheme (MCS).

The resource pool is a resource pool selected by the OBU. The self-selected resource pool can be used in the scenario where the OBU is within or outside the coverage of the RSU. Within the RSU coverage, the RSU determines whether the OBU uses autonomously selected resources.

The allocation further includes: the RSU sends a resource allocation notification message.

The resource allocation notification message is sent by a broadcast message or a dedicated RRC (Radio Resource Control) message.

It should be noted that, in addition to the high-priority V2X service notification, the RSU needs to allocate a corresponding resource pool for non-high priority or normal V2X service notifications. The resource pool is selected from the uplink Uu port resources in the LTE network.

In step S502, the OBU determines whether there is a high priority V2X service transmission, and if yes, proceeds to step S503, otherwise proceeds to step S504.

The high-priority V2X service needs to be defined and saved in the OBU in advance. The OBU judges whether it is a high-priority V2X service according to the comparison relationship between the received service attribute and the definition of the high-priority service type. If it is compared with each other, it is a high priority. Level V2X service, otherwise it is a non-high priority V2X service or a normal V2X service.

It should be noted that step S501 and step S502 may exchange order in some cases, such as when the RSU allocates high priority V2X service notification resources by using dedicated RRC signaling.

Step S503, the OBU selects a resource to send a high priority V2X service notification.

The OBU selects a resource in the high priority V2X service resource pool specified in step S501 to send a high priority V2X service notification.

The OBU divides the high-priority V2X service into important information or secondary information, and the important information and the secondary information are separately sent. The important information is sent by the high-priority V2X service notification, and the secondary information is the high-priority V2X service information. .

In addition, the OBU is in an RRC connection (RRC_Connected) or RRC idle (RRC_Idle) mode, and the OBU sends a service notification at a time specified by the resource pool, and the transmission is broadcast or more. Broadcast mode; the OBU located in the neighboring area listens to the high priority V2X service notification receiving resource pool and reads the corresponding service notification message.

It should be noted that the resource pool includes: a sending resource pool and a receiving resource pool, wherein the high-priority V2X service notification sending resource pool and the ordinary V2X service notification sending resource pool are independent of each other, and the high-priority V2X service notification receiving resource pool and The common V2X service notification resource pools are also independent of each other. The OBUs respectively listen to V2X service notification messages of different priorities.

If the D2D discovery is used to transmit the high-priority V2X service notification, the content discovered by the D2D itself is a high-priority V2X service, and the content is transparent to the access layer, that is, the access layer sends the content to the upper layer to obtain the high priority required. Level V2X service content; if the D2D communication control channel is used to transmit the high priority V2X service notification, the D2D communication data channel is used to transmit the high priority V2X service information, and the resource location of the D2D communication data channel is indicated in the D2D communication control channel, The monitoring OBU can further obtain the required high priority V2X service information according to the received notification message.

It should be noted that if two or more OBUs simultaneously select the same resource to send a service notification, a resource request conflict occurs. Even if there are fewer OBUs that send high-priority services at the same time, resource conflicts may occur as long as two or more OBUs simultaneously initiate requests. If a conflict occurs, the conflicting OBU generally retreats after a random time.

Step S504, the OBU sends a non-high priority V2X service notification.

The non-high priority V2X is a normal V2X service notification, and the OBU selects a resource for sending a normal or non-high priority V2X service notification in a resource pool allocated for the normal V2X service notification. In the embodiment of the present invention, the common V2X service and the non-high priority V2X service have the same meaning.

If the D2D discovery is used to transmit the normal V2X service notification, the content of the D2D discovery is a normal V2X service, and the content is transparent to the access layer, that is, the access layer sends the content to the upper layer to obtain the required ordinary V2X service content; The D2D communication data channel is used to transmit the normal V2X service information, and the D2D communication data channel is used to transmit the normal V2X service information, and the resource location of the D2D communication data channel is indicated in the D2D communication control channel, and the monitoring OBU further according to the received notification message. You can get the required V2X business information.

It should be noted that, in this alternative embodiment, the OBU is equivalent to a user equipment (UE).

The present application is described in detail below in conjunction with the specific embodiments of the optional embodiments of the present invention.

In step S601, the RSU allocates an autonomous selection resource pool of the high priority V2X service notification.

The self-selected resource pool is used by the OBU to independently send a high-priority V2X service notification; the RSU notifies the allocated resource pool through a system broadcast message or a dedicated RRC message. Considering the importance of the high-priority V2X service, the parameters of the resource pool are generally different from those of the ordinary V2X service resource pool, such as a shorter period and a more conservative MCS.

In step S602, the RSU instructs the OBU to independently select a resource.

The RSU instructs the OBU to independently select a resource through a system broadcast message or a dedicated RRC message.

In step S603, the OBU determines whether there is a high priority V2X service, and if yes, proceeds to step S604, otherwise, proceeds to step S605.

The OBU determines whether there is a high priority V2X service according to a predefined rule or an indication of the RSU. If the definition rule is met or the RSU indicates that the service is a high priority, the OBU determines that there is a high priority V2X service.

Step S604, the OBU selects a resource for sending a high priority V2X service notification.

The OBU selects resources in the high priority V2X service notification resource pool. The OBU is in RRC_Connected or RRC_Idle mode. The OBU sends a service notification at the time specified by the resource pool or immediately. The OBU monitors the high-priority V2X service notification receiving resource pool and reads the corresponding service notification message.

The OBU of the neighboring area can determine whether the received service notification message is a high priority V2X service notification according to the location of the resource pool.

Step S605, the OBU selects a resource for sending a normal V2X service notification.

The OBU selects a resource in the normal service notification resource pool. If the D2D discovery is used to transmit the V2X service notification, the OBU selects the D2D discovery resource to send the service notification. The D2D communication transmits the V2X service notification, and the OBU first transmits the control signaling through the D2D communication control channel, and then transmits the V2X service data according to the location indicated by the foregoing control signaling.

Embodiment 2

In step S701, the RSU pre-allocates the D2D discovery resource pool.

The pre-allocation is performed when the OBU is in the RSU coverage and is notified to the OBU (the OBU stores the pre-allocated resources), or directly stored in the OBU (such as a USIM (Universal Subscriber Identity Module) card); Pre-allocation is generally done by the RSU. The resource pool includes: a sending resource pool and a receiving resource pool. The sending resource pool is configured to send a high-priority V2X service notification outside the RSU coverage, and the receiving resource pool is used by the OBU to monitor the high-priority V2X service notification outside the RSU coverage.

Step S702, the RSU instructs the OBU to independently select a resource.

In step S703, the OBU determines whether there is a high priority V2X service, and if yes, proceeds to step S704, otherwise, proceeds to step S705.

Step S704, the OBU selects a resource for sending a high priority V2X service notification.

The OBU selects resources in the high priority v2X service notification resource pool. The OBU is in the RRC_Idle mode. The OBU sends a service notification at the time specified by the resource pool or immediately. The OBU monitors the high-priority V2X service notification receiving resource pool and reads the corresponding service notification message.

Step S705, the OBU selects a resource for sending a normal V2X service notification.

The OBU selects resources in the normal service notification resource pool, if D2D discovery is adopted. When the V2X service notification is transmitted, the OBU selects the D2D discovery resource for sending the service notification; if the D2D communication is used to transmit the V2X service notification, the OBU first sends the control signaling through the D2D communication control channel, and then sends the V2X according to the location indicated by the control signaling. Business data.

In step S803, the OBU determines whether there is a high priority V2X service, and if yes, proceeds to step S804, otherwise, proceeds to step S805.

Step S804, the OBU selects a resource for sending a high priority V2X service notification.

The OBU selects resources in the sending resource pool. The OBU is in RRC_Connected or RRC_Idle mode. The OBU sends a service notification at the time specified by the resource pool or immediately, and the OBU listens to receive the resource pool in the neighboring area, and reads the corresponding service notification message.

While the OBU sends the service notification by selecting the resource, the resource configuration information of the D2D communication data channel, such as the resource location, the OBU identifier, the received OBU identifier, and the MCS, is also sent on the resource; the monitored OBU is based on the resource configuration information. The required high priority V2X service information is obtained on the corresponding D2D communication data channel.

Step S805, the OBU selects a resource for sending a normal V2X service notification.

The OBU selects a resource in the normal service notification resource pool. If the D2D discovery is used to transmit the V2X service notification, the OBU selects the D2D discovery resource to send the service notification. If the D2D communication is used to transmit the V2X service notification, the OBU first controls through the D2D communication. The channel transmits control signaling, and then transmits V2X service data according to the location indicated by the above control signaling.
