After finding the start position of the window corresponding to the system information corresponding to the car networking information, the UE2 starts to continuously monitor the PDCCH of each subframe one by one, if the SI-RNTI is found, it indicates that the system information SI is on the next PDSCH, and meanwhile, the UE receives the system information on the corresponding PDSCH through the indication information (such as TB transport block, modulation and coding scheme, HARQ, etc.) of the PDCCH. And if the SI-RNTI is not found on the PDCCH, the system information does not exist on the PDSCH of the subframe, and the PDCCH is directly detected by jumping to the next subframe.

As shown in fig. 4, after the UE2 in vehicle B receives the system information containing the car networking information, if an out-of-control warning information type is detected from the car networking SIB, the out-of-control warning information is further parsed and delivered to a higher layer protocol layer or a car networking protocol layer. When the internet protocol layer of the UE2 receives the warning of the runaway, the UE2 further determines whether the event is related to vehicle B in which the UE2 is installed and issues a warning to the driver.

Among other things, this embodiment can be applied to a car networking framework as shown in fig. 3 b. The RSU base stations are connected with the UE1, the UE2, and the MBMS content server, respectively. When the vehicle A installed with the UE1 suddenly brakes and stops in the middle of the road, the Internet of vehicles application layer of the UE1 generates a warning vehicle warning DENM message and sends the warning vehicle warning DENM message to surrounding vehicles.

Specifically, the UE1 sends the information to the MBMS content server, and the MBMS content server/BMSC/MBMS gateway delivers the information to one or more RSU base stations in the vicinity of the UE 1. The RSU base station broadcasts the transmission period of the Internet of vehicles information, the frame offset of the Internet of vehicles information transmission, the subframe offset of the Internet of vehicles information transmission, the time duration of the Internet of vehicles information transmission, the retransmission times of the Internet of vehicles information and the like in the Internet of vehicles system information. The invention is not limited to the above transmission opportunity configuration information form, and the RSU base station may also broadcast and transmit other parameter configuration information as long as the UE can obtain the period of the transmission of the car networking information, the starting position of the subframe in the period, and the duration. In addition, the RSU base station also broadcasts the car networking bearer configuration information, such as logical channel identifier, logical channel group identifier, sequence number field size, reordering timer, maximum connection identifier, compression algorithm, PDCP sequence number size, information indicating whether to encrypt, in the car networking system information. After the RSU receives the DENM message of warning vehicle from the traffic safety server, the RSU base station can broadcast and send the DENM message of warning vehicle at the next moment of vehicle networking information transmission.

As shown in fig. 5, UE2 in the coverage of RSU base station is interested in receiving the car networking information, and then UE2 obtains the car networking system information, the car networking transmission time and the car networking bearer configuration information according to the received car networking SIB. The UE2 determines a starting subframe corresponding to the transmission of the Internet of vehicles information in the Internet of vehicles information transmission period according to the transmission time information, and starts to continuously monitor the PDCCH of each subframe one by one in the duration of the Internet of vehicles transmission time, if the V-RNTI defaulted by the system or pre-configured by the system is found, the UE indicates that the next PDSCH has the Internet of vehicles information, and receives the Internet of vehicles information on the corresponding PDSCH. If the UE2 has received the internet of vehicle information on a number of subframes corresponding to the number of retransmissions of the internet of vehicle information, the UE2 may not continue to listen for subsequent subframes within the duration of the internet of vehicle transmission opportunity. After completing the receiving of the car networking information, the UE2 parses the data packet containing the car networking information. If the UE2 has not established the car networking bearer, the UE2 may establish the car networking bearer according to the broadcast car networking bearer configuration information in the car networking system information, and deliver the data packet containing the car networking information to a logical channel/RLC receiving entity/PDCP receiving entity corresponding to the car networking bearer, and finally deliver the analyzed warning DENM message of the vehicle to a higher layer protocol layer or a car networking protocol layer. Upon receipt of the warning vehicle alert DENM message by the internet protocol layer of the UE2, the UE2 further determines whether the event is associated with the vehicle in which the UE2 is installed and issues a warning to the driver.

Among them, the present embodiment can be applied to a car networking framework among car networking frameworks as shown in fig. 3 c. The RSU base stations are connected to the UE1, the UE2, and the traffic safety server, respectively, and one traffic safety server may be connected to a plurality of RSUs, where the RSUs are not limited to the RSU base stations. The RSU detects the number of traffic vehicles, the average speed of the vehicles, the presence or absence of pedestrians, the occurrence or absence of accidents, etc. using various sensors. The RSU sends the detected Internet of vehicles information related to the RSU of the adjacent area to the traffic safety server, and only the Internet of vehicles information related to the coverage area of the RSU is directly sent to the vehicles. Receiving the vehicle networking information related to the RSU of the adjacent area sent by the RSU, the traffic safety server can judge whether to send the vehicle networking information to one or more adjacent RSUs through the cellular core network.

The RSU base station broadcasts the supported Internet of vehicles information/service types in the Internet of vehicles system information and different Internet of vehicles information transmission periods corresponding to the different Internet of vehicles information/service types, Internet of vehicles information transmission frame offset, Internet of vehicles information transmission subframe offset, Internet of vehicles information transmission time duration, Internet of vehicles information retransmission times and the like. The invention is not limited to the above transmission opportunity configuration information form, and the RSU base station may also broadcast and transmit other parameter configuration information as long as the UE can obtain the period, the subframe start position and the duration of the transmission of the car networking information corresponding to the specific car networking information/service type within the period. And for the vehicle networking information generated by the RSU or received by the RSU from the traffic safety server, the RSU judges that the broadcast transmission is needed in the cell, and the RSU broadcasts and sends the vehicle networking information at the next vehicle networking information transmission time corresponding to the vehicle networking information/service type.

As shown in fig. 6, a vehicle UE2 in the RSU coverage area is interested in receiving specific types of car networking information, and then the UE2 acquires car networking system information, car networking transmission timing, and car networking bearer configuration information according to the car networking SIB that has been received. The UE2 judges that the RSU broadcasts the car networking information/service type which is interested by the RSU according to the car networking system information, then the UE2 determines the initial subframe, corresponding to the car networking information transmission, in the car networking information transmission period according to the transmission timing information corresponding to the car networking information/service type, and starts to continuously monitor the PDCCH of each subframe one by one within the car networking transmission timing duration, if the V-RNTI preconfigured by the system is found, the fact that the next PDSCH has the car networking information is indicated, and the UE receives the car networking information on the corresponding PDSCH. After completing the receiving of the car networking information, the UE2 parses the data packet containing the car networking information. If the UE2 has established the car networking bearer, the UE2 delivers a data packet containing car networking information to a logical channel/RLC receiving entity/PDCP receiving entity corresponding to the car networking bearer, and finally delivers the analyzed car networking message to a higher layer protocol layer or a car networking protocol layer, and after the car networking protocol layer of the UE2 receives the car networking message, the UE2 further judges whether the information is related to a vehicle in which the UE2 is installed, and sends a prompt or warning to a driver.

As an alternative embodiment, in practical application, a vehicle A and a vehicle B are taken as an example for description, wherein the vehicle A is installed with a UE1 with a car networking function, the vehicle B is installed with a UE2 with a car networking function, the UE1 and the UE2 are in an E-UTRAN network coverage state, and the E-UTRAN network supports the car networking function. The embodiment can be applied to any one of the two car networking frameworks shown in fig. 3a or 3 c.

Specifically, the UE1 in the idle state receives the car networking system information sent by the base station in a broadcast manner, where the car networking system information includes car networking information/service types that the UE1 is interested in, but the base station does not broadcast the transmission time of the specific car networking information. At this time, the UE1 is interested in receiving specific types of car networking information, and then sends the car networking information/service types that the UE1 is interested in to the base station, requesting the base station to send car networking information reception configuration information corresponding to the car networking information/service types of interest.

As shown in fig. 7, the request information sent by the UE1 to the base station may include an indication of interest in receiving car networking information, a car networking service/application/information type that is of interest to the UE1, and the like. After receiving the request information, the base station sends the car networking configuration information corresponding to the request information to the UE 1. The vehicle networking configuration information may include a vehicle networking information transmission cycle, a vehicle networking information transmission frame offset, a vehicle networking information transmission subframe offset, and a vehicle networking information transmission subframe pattern corresponding to the vehicle networking information/service type that the UE1 is interested in. The invention is not limited to the above transmission time configuration information form, and the base station can also broadcast and send other parameter configuration information as long as the UE can obtain the cycle of the vehicle networking information transmission corresponding to the specific vehicle networking information/service type, and the subframe position of the vehicle networking information is transmitted in the cycle.

After the base station receives the car networking information reported by the UE in the cell or receives the car networking information from the traffic safety server, when the base station judges that broadcast transmission is needed in the cell, the base station broadcasts and sends the car networking information corresponding to the car networking information/service type at the next car networking information transmission time corresponding to the car networking information/service type.

The UE1 determines the subframes for transmitting the car networking information within the car networking information transmission period corresponding to the type of the car networking information transmission according to the transmission opportunity information corresponding to the car networking information/service type interested by the UE1 configured by the base station, monitors the PDCCH on the subframes, and if the V-RNTI pre-configured by the system is found to indicate that the car networking information exists on the next PDSCH, the UE1 receives the car networking information on the corresponding PDSCH. After the receiving of the car networking information is completed, the UE1 parses the data packet containing the car networking information, and delivers the parsed car networking information to a higher layer protocol layer or a car networking protocol layer. Upon receipt of the vehicle networking message by the vehicle networking protocol layer of the UE1, the UE1 further determines whether the message is related to the vehicle in which the UE1 is installed and issues a prompt or warning to the driver.

Specifically, the UE1 instructs the base station to send supported car networking information to the UE1 after receiving the car networking system information sent by the base station through broadcasting. When the UE1 is interested in receiving specific types of car networking information, the UE1 sends the car networking information/traffic types that the UE1 is interested in to the base station, requesting the base station to send car networking information reception configuration information corresponding to the car networking information/traffic types of interest. The embodiment can be applied to any one of the three car networking frameworks shown in fig. 3a, 3b or 3 c.

As shown in fig. 8, the request information requesting the base station to transmit the car networking information receiving configuration information corresponding to the car networking information/service type of interest may include a car networking information receiving interest indication, a car networking service/application/information type of interest of the UE1, and the like. After receiving the request information, the base station sends, to the UE1, vehicle networking configuration information corresponding to the request information, where the vehicle networking configuration information may include a vehicle networking group air interface network temporary identity (G-RNTI) corresponding to the vehicle networking information/service type that the UE1 is interested in. In addition, the base station may also send car networking bearer configuration information to the UE1, such as a sequence number field size, a reorder timer, a maximum connection identification, a compression algorithm, a PDCP sequence number size, information indicating whether to cipher, etc. Further, after the base station receives the car networking information reported by the UE in the coverage area of the base station, the car networking information is received from the traffic safety server, or the car networking information is received from the MBMS gateway, the base station uses the G-RNTI to broadcast and send the car networking information.

The UE1 configures a corresponding receiving bearer according to the base station configured car networking bearer configuration information, and then the UE1 starts detecting PDCCH in cellular downlink subframes, and if G-RNTI configured by the base station is found, which indicates that there is car networking information interested by the UE1 on the next PDSCH, the UE receives the car networking message on the corresponding PDSCH. After the car networking information is received, the UE1 parses the data packet containing the car networking information, delivers the data packet containing the car networking information to a logical channel/RLC receiving entity/PDCP receiving entity corresponding to the car networking bearer, and finally delivers the parsed car networking information to a higher protocol layer or a car networking protocol layer. Upon receipt of the vehicle networking message by the vehicle networking protocol layer of the UE1, the UE1 further determines whether the message is related to the vehicle in which the UE1 is installed and issues a prompt or warning to the driver.

As an alternative embodiment, in practical application, a vehicle A and a vehicle B are taken as an example for description, wherein the vehicle A is installed with a UE1 with a car networking function, the vehicle B is installed with a UE2 with a car networking function, the UE1 and the UE2 are in an E-UTRAN network coverage state, and the E-UTRAN network supports the car networking function. The embodiment can be applied to any one of the three car networking frameworks shown in fig. 3a, 3b or 3 c.

Specifically, after receiving the car networking system information sent by the base station in a broadcast manner, the UE1 instructs the base station to support car networking information transmission. When the UE1 is interested in receiving certain types of car networking information, the UE1 sends car networking information/traffic types to the base station that the UE1 is interested in requesting the base station to send car networking information reception configuration information.

As shown in fig. 9, the request information requesting the base station to transmit the car networking information receiving configuration information may include car networking services/applications/information types, etc. that are of interest to the UE 1. After receiving the information, the base station judges that the UE interested in the vehicle networking type information in the cell is smaller than a system threshold, and then the base station decides to send the vehicle networking information to the UE1 in a unicast mode through the C-RNTI.

The UE1 detects the PDCCH on the cellular downlink subframe, and if the C-RNTI configured by the base station is found, which indicates that there is information to be sent to the UE1 on the next PDSCH, the UE1 receives the data message on the corresponding PDSCH. After the data information is received, the UE1 parses the data packet, and finally delivers the parsed car networking message to a higher layer protocol layer or a car networking protocol layer. Upon receipt of the vehicle networking message by the vehicle networking protocol layer of the UE1, the UE1 further determines whether the message is related to the vehicle in which the UE1 is installed and issues a prompt or warning to the driver.

Specifically, the UE1 in the idle state, after receiving the car networking system information sent by the base station broadcast and containing the car networking information/service type interested by the UE1, indicates that the information is being transmitted by unicast. The UE1 is interested in the received specific type of car networking information, the UE1 sends car networking information/service type that the UE1 is interested in to the base station, requests the base station to send car networking information of a type corresponding to the car networking information/service type of interest, which may include in the request information car networking information of the type corresponding to the car networking information/service type of interest, car networking service/application/information type that the UE1 is interested in, etc.

As shown in fig. 10, after receiving the request information corresponding to the interested car networking information/service type, the base station determines whether the current number of UEs interested in the car networking type information in the cell is greater than a system threshold, and if so, the base station determines to send the car networking information of the type in a multicast manner. The base station sends the vehicle networking configuration information to the UE1, wherein one or more vehicle networking group air interface network temporary identities (G-RNTIs) corresponding to the vehicle networking information/traffic types in which the UE1 is interested may be included in the vehicle networking configuration information. In addition, the base station may also send to the UE 1a vehicle networking information transmission period, a vehicle networking information transmission frame offset, a vehicle networking information transmission subframe pattern corresponding to the vehicle networking information/traffic type of interest to the UE 1. The invention is not limited to the above transmission opportunity configuration information form, and the base station may also broadcast and send other parameter configuration information as long as the UE1 can obtain the period of the transmission of the car networking information corresponding to the specific car networking information/service type, and the subframe position of the transmission of the car networking information in the period.

After the base station receives the vehicle networking information reported by the UE in the coverage area, or receives the vehicle networking information from the traffic safety server, or receives the vehicle networking information from the MBMS gateway, the base station uses the G-RNTI broadcast corresponding to the vehicle networking information/service type to transmit the vehicle networking information.

The UE1 determines the subframes for transmitting the Internet of vehicles information within the Internet of vehicles information transmission period corresponding to the type of Internet of vehicles information transmission according to the transmission opportunity information corresponding to the Internet of vehicles information/service type interested by the UE1 configured by the base station, monitors PDCCH on the subframes, and if G-RNTI configured by the base station is found, which indicates that the Internet of vehicles information interested by the UE1 is on the next PDSCH, the UE1 receives the Internet of vehicles information on the corresponding PDSCH. After the receiving of the car networking information is completed, the UE1 parses the data packet containing the car networking information, and delivers the parsed car networking information to a higher layer protocol layer or a car networking protocol layer. Upon receipt of the vehicle networking message by the vehicle networking protocol layer of the UE1, the UE1 further determines whether the message is related to the vehicle in which the UE1 is installed and issues a prompt or warning to the driver.

As can be seen from the foregoing embodiments, the base station or the RSU may send the car networking information to the UE of the vehicle or the pedestrian interested in the car networking information in the base station or the RSU by broadcasting, multicasting, unicasting, or the like. The method and the device support the assembly of the Internet of vehicles information into a plurality of Internet of vehicles information packets according to different Internet of vehicles information/service types, priorities and emergency degrees and configure different transmission opportunities for one-time or multiple-time transmission.
