It should be noted that the application scenario shown in fig. 1 is only one scenario to which the data transmission method provided in the embodiment of the present application can be applied, and does not represent that the method provided in the embodiment of the present application must be applied to this scenario. The scenario shown in fig. 1 includes a data transmission device 101 and a terminal device 102.
Wherein the data transmission device 101 is capable of transmitting a beam of electromagnetic waves and carrying information for transmission on the beam. Illustratively, the data transmission device 101 may include a base station, a satellite, or the like. The base station may be a base station in a mobile communication network, for example, an evolved node B (eNB).

Example one
A first data transmission method provided in an embodiment of the present application is applied to a user plane function device, and a scenario shown in fig. 1 is combined to describe in detail a data transmission method provided in an embodiment of the present application, it should be noted that fig. 1 is only an application scenario of the data transmission method provided in the first embodiment of the present application, and does not represent that the data transmission method must be applied to the scenario shown in fig. 1, and specifically may be applied to a data transmission device, referring to fig. 2, fig. 2 is a flowchart of the data transmission method provided in the first embodiment of the present application, and the method includes the following steps:
step 201, obtaining target data to be transmitted.
The target data may be any data, and may include, for example, broadcast data (e.g., public information), access data (e.g., access channel configuration information or paging information), service data (e.g., application layer data), and the like, and may be generated by the data transmission device or transmitted by another device.
Step 202, according to the data type of the target data, determining a beam type corresponding to the target data in at least two beam types.
The data type of the target data may include various types, for example, broadcast data, access data, service data. The broadcast data is data transmitted in a broadcast manner, and the broadcast data may include public information; the access data is data for the terminal device to access the data transmission device, and the access data may include access channel configuration information and/or paging configuration information; the service data may include data that the application layer provides services to the user, such as application layer messages, video data, voice data, image data, and so forth.
The beam types may include broadcast beams, access beams, service beams, and the like. Wherein the broadcast beam is a beam that broadcasts within the coverage of the data transmission device; the access beam is a beam which scans a plurality of wave positions in the coverage range of the data transmission equipment and is used for the access of the terminal equipment; the service beam is used for a beam carrying service data of the user. Optionally, in a specific implementation manner, determining, according to a data type of the target data, a beam type corresponding to the target data in at least two beam types includes: if the data type of the target data is broadcast data, determining that the beam type corresponding to the target data is a broadcast beam; or if the data type of the target data is the access data, determining that the beam type corresponding to the target data is the access beam; or, if the data type of the target data is the service data, determining that the beam type corresponding to the target data is the service beam.
And 203, determining a target beam carrying the target data according to the beam type corresponding to the target data.
As described in connection with step 203, the target beam may include a broadcast beam, a receive beam, and a service beam, where the number of broadcast beams may be one, and the number of receive beams and service beams may be one or more. For example, if the target data is broadcast data, the target beam is a broadcast beam; if the target data is an access beam, the target beam is an access beam, when the access data needs to be sent through the access beam, the terminal equipment determines the access beam corresponding to the terminal equipment based on the broadcast data, and when the access beam scans the position of the terminal equipment, the access is carried out through the access beam; and if the target data is service data, configuring a service beam for the terminal equipment, and transmitting the target data through the service beam.
Optionally, with reference to the implementation manner in step 202, in an example, determining a target beam carrying target data according to a beam type corresponding to the target data includes: when the target data comprises service data of at least two service functions, configuring service beams for the service data according to a preset priority order of the service functions, and allocating network resources. For example, the service function may include a query request, a message transmission, a video transmission, an audio call, and the like, and the service function may be set by itself according to a service provided for a user, which is not listed here. The network resources may include time domain resources and frequency domain resources, and how to allocate the network resources may be determined according to a location of the terminal, for example, allocating the network resources may include allocating bandwidth for the target data, which is merely an exemplary illustration and is not meant to limit the present application.
Based on the above example, optionally, the method may further include: and receiving a priority adjusting command sent by the management terminal, and updating the priority sequence of the service functions according to the priority adjusting command, wherein the priority adjusting command is used for instructing a manager to adjust the priority sequence of the service functions. The administrator can adjust the priority sequence of the service functions by himself, and the priority can be set more flexibly, so that the data transmission efficiency is more suitable for the user requirements. For example, the current service type may be displayed at the management terminal, and the administrator may adjust the priority order of different service functions, and may also allocate network resources to different service functions, for example, set data transmission priority for different service functions, and allocate bandwidth.
Based on the above example, optionally configuring a service beam for service data and allocating network resources, including: and configuring the transmitting power and the transmitting direction of the service beam according to the position of the terminal equipment, so that the service beam covers the position of the terminal equipment, and allocating network resources. Optionally, when the terminal device accesses the data transmission device, the location information and the address information of the terminal device may be sent to the data transmission device, so that the data transmission device configures a service beam for the terminal device.
And step 204, transmitting the target data to the terminal equipment by using the target beam.
In conjunction with the implementation described in step 202, three application scenarios are listed here to respectively describe the broadcast beam, the access beam, and the service beam.
Optionally, in a first application scenario, a broadcast beam is described, where a target beam is the broadcast beam, target data is common information to be broadcast, and the sending of the target data to a terminal device by using the target beam includes: and broadcasting the public information in the coverage range of the data transmission equipment by using the broadcast beam so that the terminal equipment can access according to the public information.
The common information is used for indicating the wave position and the configuration condition of the access wave beam in the coverage area of the data transmission equipment. It should be noted that the coverage area of the broadcast beam is the coverage area of the data transmission device, because the coverage area of the broadcast beam is larger, and the beam performance is lower under the same condition, for example, the beam performance may include a data rate, a capacity, and the like provided by the beam. Thus, the broadcast beam can transmit basic common information. Alternatively, in conjunction with the scenario shown in fig. 1, the data transmission device may be a base station or a satellite, and the coverage area of the data transmission device may be a cell, and a cell may be an area covered by a signal of a base station.
Optionally, the common information includes wave position information and access beam configuration information; the wave bit information is used for indicating at least one of the position of the wave bit and the current time stamp; the access beam configuration information is used for indicating at least one of a corresponding relation between the access beam and the wave position, a scanning interval of the access beam, uplink access channel configuration information of the access beam and paging configuration information. Illustratively, in one particular implementation, the wave bit information may indicate the number of wave bits, the position of the wave bits, and the current timestamp; the access beam configuration information may indicate the number of access beams, a correspondence between each access beam and a wave position, and a scanning interval of the access beams, and may further include at least one of uplink access channel configuration information and paging configuration information of the access beams.
The wave bit quantity indicates the quantity of all wave bits in the coverage range of the data transmission equipment, and the wave bits generally indicate the positions covered by the wave beams at certain angles in azimuth or elevation; the position of the wave position indicates a physical position corresponding to the wave position, such as a Global Positioning System (GPS) coordinate; the current timestamp indicates the time at which the broadcast beam carrying the common information was transmitted. It should be further noted that there may be one or more access beams of the data transmission device, and the number of the access beams represents the number of the access beams configured by the data transmission device; the corresponding relation between each access wave beam and the wave position represents the wave position covered by each wave beam, namely the corresponding wave position; the scanning interval of the access beam may represent the time for the access beam to scan one wave bit, that is, the time for covering one wave bit, or may be replaced by a scanning period, where the scanning period is used to represent the time for each access beam to complete one scanning for all the corresponding wave bits, or is used to represent the time length of the interval between two adjacent scans for one wave bit. In addition, the uplink access channel configuration information of the access beam may include address information (e.g., port address or port number for uplink access, address of the data transmission device), channel name, and the like; the paging configuration information may include a name, an address, and the like of a paging object, and the paging object may be a destination device (terminal device) that transmits downlink data. This is merely an example and does not represent a limitation of the present application.
Optionally, in a second application scenario, an access beam is described, where the target beam is an access beam, and the target data is access data, and specifically, the target data may include access channel configuration information or paging configuration information. Transmitting target data to the terminal equipment by using the target beam, wherein the method comprises the following steps: if the data type of the target data is access data, scanning M wave positions corresponding to the access wave beam in the coverage range of the data transmission equipment by using the access wave beam carrying access channel configuration information or paging configuration information, wherein the coverage range of the access wave beam is N wave positions, M and N are positive integers, and M is larger than N. For example, an access beam may cover N wave bits in one time period, and therefore, the transmission direction and the transmission power need to be adjusted, and each of M wave bits may be covered in a plurality of time periods when other wave bits are covered in the next time period.
Here, a specific example is taken for explanation, and optionally, scanning M wave bits corresponding to the access beam in the coverage area by using the access beam includes: and in the coverage range, periodically adjusting the transmitting power and the transmitting direction of the access beam, so that the access beam periodically covers each wave position in the M wave positions. For example, taking M as 8 and N as 1 as an example, that is, the access beam can only cover one wave bit at the same time, the length of time for the access beam to scan one cycle is 8 time segments, within one cycle, the 1 st time segment covers the 1 st wave bit, the 2 nd time segment covers the 2 nd wave bit … …, the nth time segment covers the nth wave bit, N is an integer within [1,8], and after 8 time segments, each wave bit is covered. For example, if a terminal device located at the 2 nd wave position needs to access, the data transmission device may be accessed through the access beam in the 2 nd time period, and accessing the data transmission device may include establishing a data transmission link between the data transmission device and the terminal device. The time period is only an exemplary time period, and may be set according to specific situations, for example, the time period may be 10ms, 0.5s, 1s, and the like, which is not limited in the present application.
Optionally, in a third application scenario, a service beam is described, where a target beam is the service beam, target data is service data, and after a terminal device accesses a data transmission device through an access beam, the service beam may be configured for the terminal device. It should be noted that the service beam is idle when there is no transmission task, or the service beam may be configured as an access beam for scanning when there is no transmission task, and after accessing the terminal device, the service beam is configured to the terminal device that needs to transmit for data transmission.
In the present application, the service beam is flexibly configurable, and after data transmission is completed by using the service beam, the service beam can be configured to other devices. Optionally, the method further comprises: after completing data transmission with the terminal device through the service beam, releasing resources of the service beam so as to reconfigure the service beam and perform data transmission with other terminal devices through the service beam. Or, optionally, after the data transmission is completed with the terminal device through the service beam, the service beam is configured as an access beam, and the corresponding wave position is scanned, so that the utilization efficiency of the beam is further improved.
The data transmission method provided by the embodiment of the application acquires target data to be transmitted; determining a beam type corresponding to the target data in at least two beam types according to the data type of the target data; determining a target wave beam carrying target data according to a wave beam type corresponding to the target data; and transmitting the target data to the terminal equipment by using the target beam. The data transmission equipment can be configured with various types of wave beams, and for different types of data, different types of wave beams can be configured for transmission, so that the utilization efficiency of the wave beams is improved, the number of the wave beams needing to be configured is reduced, the size and the complexity of the antenna are further reduced, and the difficulty and the cost of the production and the maintenance of the equipment are reduced.

And the terminal equipment determines the scanning time of the wave position where the access wave beam is scanned to the terminal equipment according to the current timestamp and the scanning interval of the corresponding access wave beam, and then establishes a data transmission link with the data transmission equipment according to the public information at the scanning time.
