Fig. 1 is a schematic diagram illustrating an implementation environment related to a data transmission method provided by various embodiments of the present disclosure, and as shown in fig. 1, the implementation environment may include a terminal 110, a first access network device 120, and a second access network device 130.
The terminal 110 may be a terminal such as a cellular phone, an electronic reader, or the like that can transmit data through the first mobile communication network or the second mobile communication network. The first mobile communication network may include a 2G network, a 3G network, or a 4G network, the second mobile communication network may include a 5G network, and in this embodiment, the second mobile communication network may support a beam (beam) that supports data transmission at a medium-high frequency point. In the following embodiments, the terminal 110 may be a terminal supporting beam and at least one first mobile communication network. And, in practical implementation, the terminal 110 may be connected with the access network device 120 through the first mobile communication network or the second mobile communication network.
The first access network device 120 may be a base station, or may be an evolved Node B (eNB) or an e-NodeB in LTE (Long Term Evolution). Optionally, the first access network device 120 and the terminal 110 establish a wireless connection through a wireless air interface, which may also be a wireless air interface based on the 4G standard (LTE system). In the present embodiment, the first access network device 120 is a device for providing the terminal 110 with a network such as a 2G network, a 3G network, or a 4G network.
The second access network device 130 is similar to the first access network device 120, except that in the present embodiment, the second access network device 130 is a base station in a 5G system that adopts a centralized distributed architecture. The second access network device 140 typically comprises a Central Unit (CU) and at least two Distributed Units (DU). A Packet Data Convergence Protocol (PDCP) layer, a Radio Link layer Control Protocol (RLC) layer, and a Media Access Control (MAC) layer are provided in the central unit; a Physical layer (PHY) protocol stack is disposed in the distribution unit, and the specific implementation manner of the second access network device 130 is not limited in the embodiment of the present invention.
Optionally, the second access network device 130 and the terminal 110 establish a wireless connection through a wireless air interface.

Fig. 2 is a flowchart illustrating a data transmission method according to an exemplary embodiment, which is exemplified by using the data transmission method in the terminal shown in fig. 1. As shown in fig. 2, the data transmission method may include the following steps:
in step 201, in the process of using the first mobile communication network, it is detected whether the data size of the data to be transmitted reaches a preset threshold.
In step 202, if the data size reaches the preset threshold, it is detected whether the current location is covered by a beam in the second mobile communication network, where a data transmission rate of the beam in the second mobile communication network is greater than a data transmission rate of the first mobile communication network.
In step 203, if the current position is covered by the beam, the data to be transmitted is transmitted through the beam.
In practical implementation, because the data transmission rate of the second mobile communication network is much greater than that of the first mobile communication network, the terminal may transmit the data to be transmitted only by using the beam, or may transmit the data to be transmitted by using the beam and the first mobile communication network in cooperation.
In summary, in the data transmission method provided in this embodiment, in the process of using the first mobile communication network, it is detected whether the data size of the data to be transmitted reaches the preset threshold; if the data size reaches a preset threshold value, detecting whether the current position is covered by a beam in a second mobile communication network, wherein the data transmission rate of the beam in the second mobile communication network is greater than that of the first mobile communication network; if the current position is covered by the beam, transmitting the data to be transmitted through the beam, namely in the process of transmitting larger data through the first mobile communication network, if the beam with higher transmission rate exists, transmitting the data to be transmitted through the beam; the problem of lower data transmission efficiency among the correlation technique is solved, reach the effect that improves data transmission efficiency.
Fig. 3 is a flowchart illustrating a data transmission method according to another exemplary embodiment, which is exemplified by using the data transmission method in the terminal shown in fig. 1. As shown in fig. 3, the data transmission method may include the following steps:
in step 301, during the process of using the first mobile communication network, it is detected whether the data size of the data to be transmitted reaches a preset threshold.
The first mobile communication network in this embodiment may be a 2G network, a 3G network, or a 4G network. The preset threshold may be a value set in a protocol, a value pre-configured by the radio access network device, or a value pre-defined in the terminal by the user, which is not limited herein. For example, the preset threshold may be 1000M default in the terminal.
In step 302, if the data size reaches a preset threshold, it is detected whether the current location is covered by a beam in the second mobile communication network, where a data transmission rate of the beam in the second mobile communication network is greater than a data transmission rate of the first mobile communication network.
If the detection result indicates that the size of the data reaches the preset threshold, the data to be transmitted is large, and at this time, in order to improve the transmission efficiency of transmitting the data to be transmitted, the terminal can detect whether the current position is covered by the beam.
Optionally, the step of the terminal detecting whether the current location is covered by the beam may include the following two possible implementations:
the first method is to monitor the broadcast message sent by the access network device and determine whether the current location is covered by the beam according to the broadcast message.
When the terminal is in an idle state, the terminal may monitor, in real time, an SIB (System Information Broadcast) sent by each access network device, where the SIB may carry capabilities of the access network device itself, such as whether beams are supported, and thus, after receiving the SIB, the terminal may determine whether beams exist at its location according to the received SIB.
Optionally, if the SIB received by the terminal carries identification information indicating that beam is supported, such as "1", the terminal may determine that beam coverage exists at the current location, and conversely, if each received SIB carries identification information indicating that beam is not supported, such as "0", the terminal may determine that beam coverage does not exist at the current location.
It should be noted that, the above-mentioned SIB includes the identification information only as an example, and when the SIB is actually implemented, the SIB may further include other content, which is not limited in this embodiment.
Secondly, sending a query request to the access network equipment, and receiving a query result sent by the access network equipment; the query request is used to query whether the current location is covered by the beam.
In the process that the terminal transmits data using the first mobile communication network, the terminal has already established an RRC (Radio Resource Control) connection with an access network device providing the first mobile communication network, and at this time, the terminal may actively initiate information interaction with the access network device, as shown in fig. 4, that is, the terminal may send an RRC query signaling to the access network device, where the RRC query signaling carries a current location of the terminal; after receiving the RRC query signaling, the access network equipment queries whether the beam exists at the current position of the terminal, and returns a query result to the terminal, wherein the query result comprises information whether the beam exists at the current position of the terminal. Optionally, the query result returned by the access network device includes a frequency point set, where the frequency point set includes frequency points of each beam at the current location of the terminal. And when the frequency point set is empty, the terminal determines that the position where the terminal is located is not covered by the beam, otherwise, if the frequency point set is a non-empty set, the terminal can determine that the position where the terminal is located is covered by the beam.
Optionally, if the detection result of the terminal is that the size of the data to be transmitted does not reach the preset threshold, the terminal may transmit the data to be transmitted through the first mobile communication network, and at this time, the process is ended.
Optionally, before this step, the terminal may further detect whether the terminal has the beam access capability, if so, this step is executed, otherwise, the flow is ended. The terminal may detect whether the terminal has the beam access capability according to its own hardware configuration, which is not limited in this embodiment.
In step 303, if the current position is covered by the beams and there are at least two beams covered at the current position, the data to be transmitted is transmitted through the beams with signal strength better than the preset condition in the at least two beams.
Specifically, the step may include:
firstly, beams in all directions are searched according to an omnidirectional time division searching technology, and the signal intensity of at least two beams obtained through searching is obtained.
In practical implementation, an omnidirectional antenna may be disposed in the terminal, and the terminal may search for beams in various directions through the omnidirectional antenna and according to an omnidirectional time division search technique. As shown in fig. 5, the access network device transmits wireless signals using beams with different orientations, and as shown in the figure, transmits wireless signals using beams with 8 different orientations, and similarly, the terminal may also transmit wireless signals using beams with different orientations, so that in each orientation of the terminal, the terminal may receive wireless signals transmitted by the access network device in different directions, for example, in the r2 direction of the terminal 530 in the figure, the terminal 530 may receive wireless signals transmitted by the access network device 510 in the t6 direction and the t5 direction in the r2 direction, and the terminal 530 may receive wireless signals transmitted by the access network device in both the t6 direction and the t7 direction in the r3 direction. Assuming that terminal 530 does not receive wireless signals in r1 and r4, for terminal 530, terminal 530 may search for beams from t6 and t5 directions in r2 direction and beams from both t6 and t7 directions in r3 direction, i.e., a total search results in 4 beams. Alternatively, assuming that the terminal 530 only searches in the r2 direction for a beam from the t6 direction, the omni-directional search result of the terminal is to include one beam.
Wherein, the signal intensity of each beam is obtained by the terminal in advance. Optionally, the step of acquiring the signal strength by the terminal includes:
if the terminal is in an idle state, after the terminal monitors the SIB sent by each access network device, if the SIB carries an index indicating that beam is supported, the terminal may measure the signal strength of each beam in each direction of the terminal according to the received index of each beam, and store the measured signal strength. Optionally, after the terminal monitors each SIB, the terminal may sweep frequency, select a beam with an intermediate frequency point higher than a preset frequency point, measure the signal intensity of the selected beam, and store the obtained signal intensity. Thus, in this step, the terminal can obtain each signal strength saved in advance.
If the terminal is in a connected state, after the terminal receives a query result returned by the access network device, the terminal can measure the signal intensity corresponding to each direction of each frequency point in the frequency point set of the query result at the current position of the terminal, and the obtained signal intensity is stored. Thereafter, the terminal acquires the signal strength saved in advance in this step.
Secondly, the beams are sequentially accessed from high to low according to the signal intensity of at least two beams.
After obtaining the signal strength of each beam, the terminal may sort the beams in the order from high to low, and then sequentially request access to the beams according to the sort.
Thirdly, when the target beam of the at least two beams is successfully accessed, the access is stopped, and the data to be transmitted is transmitted through the accessed target beam.
After the target beam is successfully accessed, the terminal may stop continuing to access and transmit the data to be transmitted through the accessed target beam. As shown in fig. 6, the terminal obtains the signal strength of each transmit-receive pair composed of the beam transmitted by the terminal itself and the beam provided by the access network device, and the transmit-receive pairs are (r3, t3), (r3, t4), (r4, t4) in sequence from high to low in signal strength. The terminal firstly requests to access the beam in the t3 direction provided by the access network equipment in the r3 direction; after the beam is failed to be accessed, the terminal requests to access the beam in the t4 direction provided by the access network equipment in the r3 direction; after the access is successful, the terminal stops continuously requesting access to the beam in the t4 direction provided by the access network device in the r4 direction. Finally, the terminal transmits the data to be transmitted through the beam in the t4 direction provided by the access network equipment accessed in the r3 direction.
Optionally, if access to a certain beam fails, the terminal may continue to request access to the next beam in order until the final access is successful, or traverse at least two beams that have been searched. When a terminal accesses a certain beam, if the number of terminals that have been accessed in the beam reaches a preset number, that is, the load of the beam is full, or when the signal of the beam is poor, the terminal may fail to access, and at this time, the terminal may continue to request access to the next beam. In addition, if the terminal cannot be successfully accessed after traversing all beams, the terminal can continue to transmit data according to the existing first mobile communication network. Optionally, in actual implementation, after a predetermined time period, the terminal may further re-request access to the beam according to the above ordering.
Optionally, if the detection result of the terminal is that there is no beam at the current location of the terminal, the terminal may transmit the data to be transmitted through the first mobile communication network.
It should be noted that, in order to ensure that the data transmission rate of the terminal is higher after the terminal accesses the beam, before the second step, the terminal may further perform the following steps: and selecting the beam with the signal intensity higher than the intensity threshold value from at least two beams.
Since the transmission rate of the data transmitted by the terminal through the beam may be lower than the transmission efficiency of the data transmitted through the existing first mobile communication network when the signal strength of the beam is poor, in this embodiment, in order to increase the data transmission rate after the terminal accesses the beam, the terminal may select the beam with the signal strength higher than the preset threshold. The intensity threshold may be a preset value in the terminal, or may also be a value that is pre-defined in the terminal by the user, and in this embodiment, the intensity threshold is generally a preset value in the terminal.
Accordingly, the second step may include: and sequentially accessing the selected beams according to the sequence of the signal intensity of the selected beams from high to low. This step is similar to the second step, and is not described herein again.
The second point to be described is that, for example, only there are at least two searched beams, in practical implementation, if there is only one beam, the terminal may directly access the beam, if the access is successful, the terminal transmits data through the accessed beam, and if the access is failed, the terminal continues to transmit data to be transmitted through the existing first mobile communication network. During actual implementation, before the terminal accesses the beam, the terminal may further detect whether the signal strength of the beam is higher than a preset threshold, and then only when the signal strength of the beam is higher than the preset threshold, the terminal may access the beam, so that it is ensured that the data transmission rate of the terminal after the terminal accesses the beam is higher, which is not limited in this embodiment.
The third point to be described is that the step 301 is an optional step, and in actual implementation, no matter how large the data size of the data to be transmitted is, the terminal may detect whether a beam exists at the current position, and further, when the beam exists, data transmission is performed through the beam. Only, in general, when the data amount is small, the terminal can already transmit the data to be transmitted through the target data network, so to reduce the processing complexity of the terminal, the terminal may perform the step 302 only when the data size reaches the preset threshold, which is not limited herein.
In summary, in the data transmission method provided in this embodiment, in the process of using the first mobile communication network, it is detected whether the data size of the data to be transmitted reaches the preset threshold; if the data size reaches a preset threshold value, detecting whether the current position is covered by a beam in a second mobile communication network, wherein the data transmission rate of the beam in the second mobile communication network is greater than that of the first mobile communication network; if the current position is covered by the beam, transmitting the data to be transmitted through the beam; that is, in the process of transmitting larger data through the first mobile communication network, if a beam with a higher transmission rate exists, the data to be transmitted is transmitted through the beam; the problem of lower data transmission efficiency among the correlation technique is solved, reach the effect that improves data transmission efficiency.
It should be added that, in the foregoing embodiments, after the terminal accesses to the beam, since the terminal may be in a moving state, in order to ensure that the terminal can continue to use the beam for data transmission during the movement of the terminal, the terminal may perform beam tracking (beam tracking), and further continuously switch the accessed beam, thereby ensuring normal transmission of data. In the beam tracking process, if the terminal cannot continue to access the beam, the terminal may continue to transmit the data to be transmitted through the first mobile communication network, for example, continue to transmit the data to be transmitted through the 4G network.
Another point to be supplemented is that, in the above embodiments, when the terminal fails to access the beam, the terminal may request access to the beam again after a predetermined period of time; when the beam is available, the terminal can transmit data through the beam, and the data transmission efficiency is improved. Optionally, when the terminal fails to successfully access to the beam, the terminal may further repeat steps 301 to 303, which is not described herein again.
It should be noted that, in each of the above embodiments, after the terminal finishes transmitting the data to be transmitted through the beam, the terminal may disconnect the beam. Certainly, the terminal may not disconnect the beam in actual implementation, which is not limited to this.
The following are embodiments of the disclosed apparatus that may be used to perform embodiments of the disclosed methods. For details not disclosed in the embodiments of the apparatus of the present disclosure, refer to the embodiments of the method of the present disclosure.
