[0031] Next, the technical solutions in the embodiments of the present application will be clearly described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0032] Terms such as "first" and "second" in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such used data may be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually of the same category, and the number of objects is not limited. For example, the first object may be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally means an "or" relationship between the associated objects before and after.

[0033] With the development of mobile communication technology, especially the technologies such as network slicing and vehicle-to-everything (V2X) have also been increasingly applied. For example, a vehicle can not only be used as a means of transportation, but also be equipped with an in-vehicle terminal to perform real-time data interaction with a communication network. Different from mobile terminals such as mobile phones and tablets, in-vehicle terminals often have stronger radio frequency capabilities, battery life capabilities, etc. than mobile terminals. Therefore, after the in-vehicle terminal accesses the communication network, the in-vehicle terminal can often have better communication network services. Currently, in a vehicle, when a user uses a mobile terminal, the mobile terminal can only access the communication network by itself, and the in-vehicle terminal does not fully utilize its own network communication advantages to provide communication network services for the mobile terminal.

[0034] In view of the above problems, the embodiments of the present application provide a data communication method, device, electronic device and readable storage medium, which can enable the communication network service of the in-vehicle terminal to be shared and used in a target mobile terminal, and realize making full use of the network communication advantages of the in-vehicle terminal itself.

[0035] Next, with reference to the accompanying drawings, the data communication method, device, electronic device and storage medium provided by the embodiments of the present application will be described in detail through specific embodiments and their application scenarios.

[0036] Figure 1 This is a schematic diagram of the architecture of a data communication system provided by an embodiment of the present application. As Figure 1 shown, the data communication system may include a vehicle-mounted terminal 110 and a mobile terminal 140. The data of the mobile terminal 140 may be multiple, such as Figure 1 the mobile terminal 141, the mobile terminal 142, and the mobile terminal 143 shown.

[0037] Among them, the vehicle-mounted terminal 110 is a communication terminal configured in a vehicle. The vehicle-mounted terminal 110 may include a user identification card registered or authenticated in the network service terminal 130. Through the user identification card, the vehicle-mounted terminal 110 may have the permission to interact with the communication network. For example, functions that require network communication connections such as vehicle intelligent driving and vehicle automated driving may be realized. A radio frequency unit is configured in the vehicle-mounted terminal 110, and information interaction with the communication network may be realized through the radio frequency unit. Since the volume of the vehicle is significantly larger than that of mobile terminals 140 such as mobile phones and tablet computers, the radio frequency unit of the vehicle-mounted terminal 110 often has a stronger radio frequency ability than that of the mobile terminal 140, so that advantages such as low latency, high bandwidth, and low power consumption may be brought during the process of information interaction with the communication network. In addition, the vehicle-mounted terminal also has an obvious endurance ability compared with the mobile terminal.

[0038] As a specific example, the mobile terminal 140 may be a terminal capable of information interaction with the communication network, such as a mobile phone, a tablet computer, a laptop computer, a palm computer, or an Ultra-Mobile Personal Computer (UMPC).

[0039] In the embodiment of the present application, the vehicle-mounted terminal establishes M first communication links with M mobile terminals respectively, and the vehicle-mounted terminal establishes N second communication links with the network service terminal. M second communication links associated one by one with the first communication links are included in the N second communication links. M is a positive integer, and N is a positive integer greater than or equal to M.

[0040] Exemplarily, the mobile terminal 141 may establish a first communication link 111 with the vehicle-mounted terminal 110 for transmitting communication data of the mobile terminal 141. For example Figure 1 the first communication link 111, the first communication link 112, and the first communication link 113 shown.

[0041] The vehicle-mounted terminal 110 may establish a second communication link with the network service terminal 130. For example Figure 1The second communication links 111, 112, and 113 shown. Exemplarily, among the multiple second communication links between the vehicle-mounted terminal 110 and the network service terminal 130, each second communication link corresponds one-to-one to the first communication link.

[0042] In some embodiments, the vehicle-mounted terminal 110 is a communication terminal configured in a vehicle. Among the N second communication links, there may further include a third communication link between the vehicle-mounted terminal 110 and the network service terminal 130. The third communication link is used to transmit communication data corresponding to the vehicle.

[0043] Exemplarily, the network service terminal 130 supports one or more communication methods such as Global System for Mobile Communication (GSM) (2G) communication, Wideband Code Division Multiple Access (WCDMA) (3G) communication, Long Term Evolution (LTE) (4G) communication, and 5G communication, etc. The above one or more communication methods can be provided by any network operator.

[0044] Exemplarily, taking the vehicle-mounted terminal 110 being able to use a 5G communication network as an example, a second communication link 121 between the vehicle-mounted terminal 110 and the network service terminal 130 can specifically be a Protocol Data Unit (PDU) session. Taking the vehicle-mounted terminal being able to use a 4G communication network as an example, a second communication link 121 between the vehicle-mounted terminal 110 and the network service terminal 130 can specifically be a Packet Data Network (PDN) connection.

[0045] In a specific example, continuing to take the vehicle-mounted terminal 110 being able to use a 5G communication network as an example, for a mobile terminal, a PDU session is established between the vehicle-mounted terminal 110 and the network service terminal 130. The PDU session may include transmission channels of multiple Quality of Service (QoS) levels. When the vehicle-mounted terminal 110 is connected to N mobile terminals 140, the vehicle-mounted terminal 110 establishes N PDU sessions with the 5G communication network. In the N PDU sessions, each PDU session can reserve transmission channels of multiple Quality of Service (QoS) levels.

[0046] According to an embodiment of the present application, after a mobile terminal establishes a first communication link with a vehicle-mounted terminal, the vehicle-mounted terminal can establish a second communication link with a communication network based on its own network communication capabilities corresponding to the mobile terminal. In this way, the mobile terminal can interact with the communication network through the vehicle-mounted terminal, thereby realizing sharing the communication network service of the vehicle-mounted terminal for use in the mobile terminal, enabling the mobile terminal to also achieve better communication network services such as low latency, high bandwidth, and low power consumption, and making full use of the network communication advantages of the vehicle-mounted terminal itself.

[0047] Figure 2 It is a flowchart of a data communication method provided by an embodiment of the present application, which may include the following steps 210 to step 220.

[0048] Step 210, receive network service data sent by a first terminal through a first target communication link, where the network service data is the network service data of a target mobile terminal among M mobile terminals.

[0049] Step 220, send the network service data to a second terminal through a second target communication link.

[0050] Step 220, transmit first communication data of the mobile terminal through a first communication link or a target communication link.

[0051] Specifically, when the first terminal is the target mobile terminal, the second terminal is a network service terminal, the M first communication links include the first target communication link, and the M second communication links include the second target communication link.

[0052] When the first terminal is a network service terminal, the second terminal is the target mobile terminal, the M first communication links include the second target communication link, and the M second communication links include the first target communication link.

[0053] Exemplarily, the target mobile terminal may be a terminal capable of interacting with a communication network such as a mobile phone, a tablet computer, a laptop computer, a personal digital assistant, or an ultra-mobile personal computer (UMPC), etc., and no specific limitation is made here.

[0054] For ease of description, the embodiments of the present application will be described below by taking the first terminal as the target mobile terminal and the second terminal as the network service terminal as an example.

[0055] When information is interacted between the target mobile terminal and the network service terminal, the network service data of the target mobile terminal is transmitted through the first target communication link and the second target communication link.

[0056] Exemplarily, when the network service data is the service data sent by the target mobile terminal to the network service terminal, the vehicle-mounted terminal receives the network service data sent by the target mobile terminal through the first target communication link, and sends the network service data to the network service terminal through the second target communication link.

[0057] When the network service data is the service data sent by the network service terminal to the target mobile terminal, the vehicle-mounted terminal receives the network service data sent by the network service terminal through the second target communication link, and sends the network service data to the target mobile terminal through the first target communication link.

[0058] In the embodiments of the present application, the target mobile terminal can implement information interaction of network service data with the network service terminal through the first target communication link and the second target communication link. Among them, since the second target communication link is the link between the vehicle-mounted terminal and the network service terminal, the network service of the vehicle-mounted terminal can be shared and used in the target mobile terminal, so that the target mobile terminal can also achieve better network services such as low latency, high bandwidth, and low power consumption. The vehicle-mounted terminal does not make full use of its own network communication advantages to provide communication network services for the target mobile terminal.

[0059] In some embodiments, the vehicle-mounted terminal can establish a first communication link with multiple mobile terminals respectively. When the mobile terminal establishes a communication link with the network service terminal, the following steps 301 to 304 can be referred to.

[0060] Step 301, the mobile terminal sends a communication network sharing request to the vehicle-mounted terminal.

[0061] The communication network sharing request is used for the mobile terminal to establish a first communication link with the vehicle-mounted terminal, and for the vehicle-mounted terminal to establish a second communication link with the network service terminal, where the first communication link is associated with the second communication link.

[0062] Step 302, the vehicle-mounted terminal receives the communication network sharing request sent by the mobile terminal.

[0063] Step 303, in response to the communication network sharing request of the mobile terminal, the vehicle-mounted terminal establishes a first communication link with the mobile terminal; and, establishes a second communication link associated with the first target communication link with the target network service terminal.

[0064] Step 304, the mobile terminal performs data communication with the network service terminal through the first communication link and the second communication link.

[0065] In an embodiment of the present application, the mobile terminal can actively send a communication network sharing request to the vehicle-mounted terminal. When the vehicle-mounted terminal allows the corresponding mobile terminal to establish a second communication link, a communication link can be quickly established for the mobile terminal, so that the mobile terminal can quickly interact with the communication network through the vehicle-mounted terminal, enabling the mobile terminal to also achieve better communication network services such as low latency, high bandwidth, and low power consumption.

[0066] In some embodiments, the number of network service terminals is at least one. The at least one network service terminal includes a target network service terminal, which is determined according to the network service registration information of the target mobile terminal.

[0067] Specifically, the target mobile terminal is registered or authenticated in the network services provided by the network operator and can use the network services provided by the network operator. The network operator retains the network service registration information of the target mobile terminal and provides corresponding network services for the target mobile terminal through the network service terminal. The communication network sharing request sent by the target mobile terminal to the vehicle-mounted terminal may include the network service registration information of the target mobile terminal. According to the network service registration information of the target mobile terminal, the vehicle-mounted terminal can establish a second communication link with the target network service terminal corresponding to the network service registration information.

[0068] In some embodiments, the vehicle-mounted terminal can establish second communication links with multiple network service terminals. For example, when the vehicle-mounted terminal receives the network service registration information of multiple target mobile terminals, it can determine the network service terminal corresponding to each target mobile terminal according to the network service registration information and establish a second communication link with the network service terminal corresponding to each target mobile terminal.

[0069] According to the embodiment of the present application, by determining based on the network service registration information of the target mobile terminal, the network service terminal corresponding to the target mobile terminal can be quickly determined, so as to be able to meet the required network service needs of different mobile terminals respectively.

[0070] In some embodiments, the mobile terminal can send an IP Multimedia Subsystem (IMS) service request to the network service terminal for the network service terminal to establish an IMS service link with the mobile terminal.

[0071] Specifically, based on the IP Multimedia Subsystem (IMS) service, the mobile terminal can make high-definition voice calls, such as Voice over Long-Term Evolution (VoLTE) calls, Voice over New Radio (VoNR) calls, etc., which are not listed one by one here.

[0072] In the embodiments of the present application, an IP multimedia system service link is directly established between the mobile terminal and the communication network, so as to ensure the communication security of the mobile terminal itself and retain the ability of the vehicle-mounted terminal to establish its own IP multimedia system service link.

[0073] In some embodiments, the network service data includes: at least one network service sub-data and a quality of service level identifier corresponding to each said network service sub-data.

[0074] Specifically, by way of example, taking the vehicle-mounted terminal being able to use a 5G communication network as an example, a second communication link between the vehicle-mounted terminal and the network service terminal may specifically be a PDU session. Taking the vehicle-mounted terminal being able to use a 4G network service terminal as an example, a second communication link between the vehicle-mounted terminal and the network service terminal may specifically be a PDN connection.

[0075] The target mobile terminal can establish communication services with different service requirements according to actual application needs. In the target communication link, each communication service may correspond to a quality of service level identifier, and different communication services may correspond to different quality of service level identifiers, which are not specifically limited herein. In the target communication link, multiple information transmission sub-channels (QoS Flow) can be established corresponding to the quality of service level identifier (QoSFlow Identity, QFI), and second communication data corresponding to the quality of service level identifier can be transmitted in each QoS Flow.

[0076] It can be understood that when the vehicle-mounted terminal is connected to multiple mobile terminals, each second communication link can achieve the functions of the target communication link and the technical effects corresponding to the target link, which will not be elaborated herein.

[0077] In the embodiments of the present application, since the information transmission sub-channels corresponding to different quality of service level identifiers have different QoS guarantee capabilities, therefore, the target communication link between the vehicle-mounted terminal and the network service terminal can provide differentiated QoS for the target mobile terminal. When there are multiple mobile terminals connected to the vehicle-mounted terminal, the communication services corresponding to the high quality of service levels in different mobile terminals can be preferentially guaranteed.

[0078] In some embodiments, when the vehicle-mounted terminal receives a communication network sharing request from the mobile terminal, it can choose to allow or not allow sharing its own network communication ability with the mobile terminal. For example, when the network signal of the vehicle-mounted terminal is poor or there is data congestion, it can choose to preferentially guarantee the communication requirements of its own communication services.

[0079] In another example, the N second communication links further include a third communication link, which is used to transmit vehicle communication data corresponding to the vehicle. When the data transmission index of the third communication link does not meet the preset index threshold, adjust the communication priorities of the N second communication links to obtain the target communication priorities, where the communication priorities of the M second communication links associated with the first communication link one by one are the first priorities, and the communication priority of the third communication link is the second priority, and the second priority is higher than the first priority; according to the target communication priorities, transmit the vehicle communication data through the third communication link.

[0080] In some embodiments, receiving the network service data sent by the first terminal through the first target communication link includes: receiving the network service data sent by the first terminal through the first target communication link according to the target communication priorities; sending the network service data to the second terminal through the second target communication link includes: receiving the network service data sent by the first terminal through the first target communication link according to the target communication priorities.

[0081] Exemplarily, the vehicle communication data, for example, may include data required for implementing vehicle intelligent driving, vehicle automated driving, etc., which need to interact with the network.

[0082] The data transmission index of the third communication link, for example, the network signal strength of the current communication network, the bit rate of the communication link, etc. Correspondingly, the preset index threshold, for example, the preset network signal strength, the preset bit rate of the communication link, etc., are not listed one by one here. The preset index threshold can be set in advance according to the communication requirements of the communication link, and no specific limitation is made here.

[0083] Exemplarily, when the communication priority of the second communication link is the first priority and the communication priority of the third communication link is the second priority, the in-vehicle terminal will transmit the vehicle communication data through the third communication link according to the target communication priorities. At this time, the ARP capability of the third communication link will be higher than the ARP capability of each second communication link. Among them, the ARP capability, for example, may include the pre-emption capability of the communication network and the pre-emption vulnerability of the communication network.

[0084] In another alternative embodiment, when the communication priority of the second communication link is the first priority and the communication priority of the third communication link is the second priority, it may further include setting the resource type of the quality of service in the second communication link. For example, the quality of service in the second communication link is adjusted to the non-guaranteed bit rate (Non-GBR) type. In this type, since Non-GBR bearers do not require fixed network resources, when the communication network is congested, the communication services in the target communication link can be maintained for a long time.

[0085] According to the embodiments of the present application, when the data transmission index of the third communication link does not meet the preset index threshold, the communication data adjustment priority of the third communication link is set to the second priority, and the communication data adjustment priority of the target communication link is set to the first priority. Since the second priority is higher than the first priority, the communication requirements of the vehicle's own communication services can be preferentially guaranteed, especially during vehicle driving, to ensure the driving safety of the vehicle.

[0086] In the data communication method provided by the embodiments of the present application, the execution subject may be a data communication device. In the embodiments of the present application, taking the data communication device executing the data communication method as an example, the data communication device provided by the embodiments of the present application is described.

[0087] Figure 3 FIG. 10 is a schematic structural diagram of a data communication device provided by an embodiment of the present application. The data communication device 300 is applied to an in-vehicle terminal. The in-vehicle terminal establishes M first communication links with M mobile terminals respectively, and the in-vehicle terminal establishes N second communication links with a network service terminal. The N second communication links include M second communication links associated with the first communication links one by one. M is a positive integer, and N is a positive integer greater than or equal to M.

[0088] Combined with Figure 3 shown in FIG. 10, the data communication device 300 includes:

[0089] A receiving module 310, configured to receive network service data sent by a first terminal through a first target communication link, where the network service data is network service data of a target mobile terminal among M mobile terminals;

[0090] A sending module 320, configured to send network service data to a second terminal through a second target communication link;

[0091] Wherein, when the first terminal is the target mobile terminal, the second terminal is the network service terminal. The M first communication links include the first target communication link, and the M second communication links include the second target communication link;

[0092] When the first terminal is a network service terminal, the second terminal is a target mobile terminal, the M first communication links include a second target communication link, and the M second communication links include a first target communication link.

[0093] In the embodiments of the present application, the target mobile terminal can implement information interaction of network service data with the network service terminal through the first target communication link and the second target communication link. Among them, since the second target communication link is the link between the vehicle-mounted terminal and the network service terminal, the network service of the vehicle-mounted terminal can be shared and used in the target mobile terminal, so that the target mobile terminal can also achieve better network service terminal services such as low latency, high bandwidth, and low power consumption. This enables the vehicle-mounted terminal not to fully utilize its own network communication advantages to provide a communication network service for the target mobile terminal.

[0094] In some embodiments, the number of network service terminals is at least one, and the at least one network service terminal includes a target network service terminal, which is determined according to the network service registration information of the target mobile terminal.

[0095] According to the embodiments of the present application, by determining based on the network service registration information of the target mobile terminal, the network service terminal corresponding to the target mobile terminal can be quickly determined, so as to be able to meet the required network service requirements of different mobile terminals respectively.

[0096] In some embodiments, the data communication device 300 further includes:

[0097] A receiving module 310, further configured to receive a communication network sharing request sent by the target mobile terminal;

[0098] A processing module, configured to establish a first target communication link with the target mobile terminal in response to the communication network sharing request of the target mobile terminal;

[0099] The processing module is further configured to establish a second target communication link associated with the first target communication link with the target network service terminal.

[0100] In the embodiments of the present application, the mobile terminal can actively send a communication network sharing request to the vehicle-mounted terminal. When the vehicle-mounted terminal allows the corresponding mobile terminal to establish a second communication link, a communication link can be quickly established for the mobile terminal, so that the mobile terminal can quickly perform information interaction with the communication network through the vehicle-mounted terminal, and the mobile terminal can also achieve better communication network services such as low latency, high bandwidth, and low power consumption.

[0101] In some embodiments, the network service data includes: at least one network service sub-data and a service quality level identifier corresponding to each network service sub-data.

[0102] In the embodiments of the present application, since the information transmission sub-channels corresponding to different quality of service level identifiers have different QoS guarantee capabilities, the target communication link between the vehicle-mounted terminal and the network service terminal can provide differentiated QoS for the target mobile terminal. When there are multiple mobile terminals connected to the vehicle-mounted terminal, the communication services corresponding to the high quality of service levels among different mobile terminals can be preferentially guaranteed.

[0103] In some embodiments, the N second communication links further include a third communication link, and the third communication link is used to transmit vehicle communication data corresponding to the vehicle; the apparatus further includes:
