Technical Field

[0001] The present invention relates to the technical field of emergency broadcasting, and in particular to a traffic accident broadcasting method, a GNODEB base station, equipment and a medium. Background Art

[0002] The Public Warning System (PWS) is a public warning mechanism designed by the 3rd Generation Partnership Project (3GPP) to respond to natural disasters, emergencies and other emergencies. It sends emergency alerts and related information to the public through mobile communication networks. In emergencies, natural disasters or other critical situations, PWS can ensure that emergency alerts are quickly and reliably communicated to the public, helping the public to take appropriate actions in time to protect their own safety. Due to the high penetration rate of mobile communication networks, PWS can cover the vast majority of the population, ensuring that emergency alerts can be transmitted to every potentially affected individual.

[0003] Among them, emergency alerts for traffic accidents are generally implemented through highway information boards to remind drivers and passengers to pay attention to traffic accidents. Highway information boards, also known as variable message signs (VMS), are a key component of highway traffic management systems. They are electronic display screens installed on both sides or in the center of highways, which can display various traffic information in real time and are mainly used to provide important traffic information to drivers. However, the construction cost of the information screens on the road is high, and they cannot be covered on a large scale with high density. Summary of the invention

[0036] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the embodiments of the present invention, many technical details are proposed in order to enable the reader to better understand the present invention. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present invention can be implemented. The division of the following embodiments is for the convenience of description and should not constitute any limitation on the specific implementation of the present invention. The various embodiments can be combined and referenced with each other without contradiction.

[0037] One embodiment of the present invention relates to a traffic accident broadcasting method, which is applied to a GNODEB base station. The implementation details of the traffic accident broadcasting method of this embodiment are specifically described below. The following content is only the implementation details provided for the convenience of understanding and is not necessary for implementing this solution.

[0038] The specific process of the traffic accident broadcasting method of this embodiment can be as follows: Figure 1 As shown, including:

[0039] Step 101, at the place where the traffic accident occurs, obtain the traffic accident information to be broadcast.

[0040] Specifically, the next generation Node B (GNODEB) base station is a base station defined by 3GPP for the 5G (NR) wireless network design, which has independent network functions, and the implementation of these functions complies with the protocol specifications of the wireless network (NR RAN) in 3GPP. In this embodiment, when a traffic accident occurs, the GNODEB base station can be moved to the place where the traffic accident occurs, and then receive the traffic accident information input by the operator according to the traffic accident situation at the place where the traffic accident occurs. Among them, the traffic accident information is the warning information that needs to be provided to the driver after the traffic accident occurs.

[0041] In one example, the GNODEB base station includes a touch screen, and an operator can input traffic accident information to the GNODEB base station through the touch screen of the GNODEB base station according to the traffic accident situation at the place where the traffic accident occurred.

[0042] Step 102, according to the road direction of the traffic accident site, set the direction of the directional antenna of the GNODEB base station so that the GNODEB base station transmits along the road direction of the traffic accident site, while enhancing the signal coverage of the GNODEB base station in the road direction of the traffic accident site, and reducing the signal coverage of the GNODEB base station in the road direction other than the traffic accident site.

[0043] Specifically, while the GNODEB base station receives the traffic accident information input by the operator based on the traffic accident conditions at the site of the traffic accident, it also receives the road direction of the traffic accident site input by the operator, so as to set the direction of the directional antenna of the GNODEB base station according to the input road direction of the traffic accident site.

[0044] In one example, an operator may input the road direction of the traffic accident location to the GNODEB base station through the touch screen of the GNODEB base station.

[0045] Since the direction of the directional antenna of the GNODEB base station is set according to the road direction of the traffic accident site, the GNODEB base station can transmit along the road direction of the traffic accident site. This can enhance the signal coverage of the GNODEB base station in the road direction of the traffic accident site while reducing the signal coverage of the GNODEB base station in the road direction other than the traffic accident site.

[0046] Step 103, the traffic accident information is sent to the air interface, and the traffic accident information is broadcasted, so that the terminal equipment can obtain the traffic accident information through the air interface within the signal coverage range of the GNODEB base station.

[0047] Specifically, the traffic accident information is first encoded using the gsm-7bit encoding format or UCS2 encoding format specified by 3GPP to generate a code stream that complies with the public warning system PWS specification, and then the generated code stream is assembled into the corresponding fields of the SIB6 message, SIB7 message or SIB8 message of the Radio Resource Control (RRC) protocol to generate the SIB6 message, SIB7 message or SIB8 message, and finally the SIB6 message, SIB7 message or SIB8 message is sent to the air interface.

[0048] Among them, the structure of the PWS system specified by 3GPP is as follows Figure 2 As shown in the figure, in the PWS system, the broadcast content needs to be encoded in the core network and the transmission range is determined, and then the encoded message is sent to one or more designated next generation base stations (Next Generation Node B, GNODEB base station), that is, the core network and GNODEB base station need to cooperate to realize the broadcast of traffic accident information. The core network is usually located in the data room, and the GNODEB base station needs to be connected through a wired or wireless network, and the broadcast content also needs to be input in the core network located in the data room. If there is a core network, it is not easy to carry the equipment to the site and directly input specific alarm content on site.

[0049] In this embodiment, there is no need to broadcast in the entire wireless network, and it is sufficient to broadcast at the location where the traffic accident occurs. Therefore, there is no need for the core network side to encode and determine the sending range. In addition, this embodiment can directly generate the message code stream that originally needs to be generated by the core network side (that is, the above-mentioned code stream that complies with the public warning system PWS specification) on the GNODEB base station side through the gsm-7bit encoding format or the UCS2 encoding format.

[0050] In a specific implementation, the GNODEB base station includes a Radio Resource Control (RRC) layer, a Medium Access Control (MAC) layer, and a Physical (PHY) layer. After obtaining a SIB6 message, a SIB7 message, or a SIB8 message, the SIB6 message, the SIB7 message, or the SIB8 message is first encoded by the RRC layer of the GNODEB base station using the ASN1 encoding format to encode the SIB6 message, the SIB7 message, or the SIB8 message into a standard code stream so that it can be received and decoded and displayed by the terminal device. The code stream is the content to be broadcasted in the end. Referring to the description of the GNODEB base station and the core network, this embodiment implements the GNODEB base station in this way to instantly generate the traffic accident information to be sent according to the on-site input without connecting to the core network.

[0051] Finally, the SIB6 message, SIB7 message or SIB8 message encoded by the RRC layer of the GNODEB base station is sent to the air interface through the MAC layer and PHY layer of the GNODEB base station in sequence, so that the terminal device can receive the encoded SIB6 message, SIB7 message or SIB8 message through the air interface within the signal coverage of the GNODEB base station, and decode it to obtain traffic accident information.

[0052] In this embodiment, when a traffic accident occurs, a direct GNODEB base station is used to obtain the traffic accident information to be broadcasted at the place where the traffic accident occurs, and the traffic accident information is sent to the air interface through the GNODEB base station, and the traffic accident information is broadcasted, so that the terminal equipment at the place where the traffic accident occurs can receive the broadcasted traffic accident information. The method is implemented at the place where the traffic accident occurs, so the GNODEB base station that implements the method can be moved at any time, can be carried to the place where the accident occurs, can cover any section of the expressway, and can realize the broadcast of traffic accidents without the need for high-density construction of information screens on the road, thereby reducing the cost of traffic accident broadcasting, and the range of GNODEB base station broadcasting is also large. Furthermore, the direction of the directional antenna of the GNODEB base station is set according to the road direction of the place where the traffic accident occurs, so that the GNODEB base station transmits along the road direction of the place where the traffic accident occurs, which can enhance the signal coverage range of the terminal equipment in the road direction indicated by the traffic accident information, while reducing the signal coverage range of the terminal equipment in the road direction not indicated by the traffic accident information, which can further enhance the range of the GNODEB base station broadcasting the traffic accident information.

[0053] In one embodiment, the traffic accident broadcasting method of the present invention can be performed as follows: Figure 3The system structure shown in the figure is implemented, and the system includes: an input module, an encoder module, a broadcast sending module and an antenna direction module.

[0054] Among them, the input module is used for the operator to input the information to be broadcast (ie, traffic accident information) and the direction of the directional antenna according to the actual situation, and sends the traffic accident information to the encoder module and sends the direction of the directional antenna to the antenna directional module.

[0055] The encoder module is used to receive and save the traffic accident information sent by the input module, and encode the text information using the gsm-7bit encoding format or UCS2 encoding format specified by 3GPP, generate a code stream that complies with the PWS system specification, assemble the code stream into the corresponding fields of the SIB6 message or SIB7 message or SIB8 message of the RRC protocol, encode the SIB6 message, SIB7 message or SIB8 message into a standard code stream using the ASN1 encoding format, and send the resulting code stream to the broadcast transmission module. The function of the encoder module enables the entire system to realize that the GNODEB base station can instantly generate the traffic accident information to be sent based on the on-site input without connecting to the core network.

[0056] The broadcast sending module is used to receive and save the code stream information sent by the encoder module, and send the code stream information to Uu (i.e., the air interface) through the MAC and PHY functions of the GNODEB base station. Ordinary mobile phones can receive and decode SIB6 messages, SIB7 messages or SIB8 messages through Uu within the signal coverage of this system to obtain traffic accident information.

[0057] The antenna directional module is used to receive and save the direction of the directional antenna sent by the input module. The antenna module adjusts the direction of the directional antenna according to the input direction to ensure that the directional antenna is transmitted along the road direction. This can not only enhance the coverage of mobile phones in the road direction, but also reduce the impact on mobile phones in non-road directions.

[0058] 1. Based on this system structure, the specific process of the traffic accident broadcasting method of the present invention can be as follows: Figure 4 As shown:

[0060] 2. Personnel set the warning information that the equipment needs to send (i.e. traffic accident information) according to the specific circumstances of the accident, and set the direction of the road according to the road conditions.

[0061] 3. The device input module sends the alarm information and direction information to the encoder module and the antenna orientation module respectively.

[0062] 4. The antenna directional module sets the antenna direction according to the direction information.

[0063] 5. The encoder module encodes the information and sends the encoded code stream to the broadcast sending module.

[0064] 6. The broadcast sending module sends the encoded code stream to the air interface.

[0065] 7. Mobile phones within the coverage of the device signal receive the sent alarm information.

[0066] 8. Drivers and passengers obtain traffic accident information through warning messages on their mobile phones.

[0067] The step division of the various methods above is only for clear description. When implemented, they can be combined into one step or some steps can be split and decomposed into multiple steps. As long as they include the same logical relationship, they are all within the protection scope of the present invention. Adding insignificant modifications or introducing insignificant designs to the algorithm or process without changing the core design of the algorithm and process are all within the protection scope of the invention.
