All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that the terms "first", "second", "third" and "fourth", etc. in the description and claims of the present application are used for distinguishing different objects, and are not used for describing a specific order. The terms "comprises," "comprising," and "having," and any variations thereof, in the embodiments of the present application, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The technical solution of the present application will be described in detail with reference to specific examples.

In order to more clearly describe a data transmission method and apparatus, an electronic device, and a storage medium disclosed in the embodiments of the present application, an application scenario applicable to the method is first introduced. Alternatively, the method may be applied to a modem (modem); in other alternative embodiments, the method may also be applied to other data forwarding devices, such as: routers, switches, etc., without limitation. The embodiments of the present application are described with reference to a modem as an example, and should not be construed as limiting the embodiments of the present application.

Referring to fig. 1, fig. 1 is a schematic view of an application scenario disclosed in an embodiment of the present application. Optionally, the input end of the modem 110 may be connected to an air interface of the network end 120, and the network end 120 may transmit downstream data to the modem 110; the output of the modem 110 may be via a data transmission line, such as: PCIe and PCI (local component interface) are connected to an Application Processor (AP) 130, and the modem 110 may forward the received downstream data to the AP 130 through a data transmission line.

The modem 110 is a short term for a modulator (modulator) and a demodulator (demodulator), and is an electronic device capable of implementing modulation and demodulation functions required for communication, and generally includes a modulator and a demodulator. At the transmitting end, a certain parameter of carrier wave form is controlled by baseband pulse to form a signal suitable for line transmission, and at the receiving end, when the modulated signal reaches the receiving end, the carrier wave of the analog signal converted by the modulator is removed to restore the original baseband digital signal.

The application processor 130 provides a manageable mechanism for accessing system resources for applications via a communication protocol. For example, application processors based on J2EE (Java 2platform, enterprise edition) technology, EJB (enterprise Java beans), JMS (Java message service), and the like, but are not limited thereto.

The network end 120 may be understood as a network end device, for example, a base station, which is not limited herein.

The network side 120 and the modem 110 communicate via an air interface, which may be an air interface based on a 5G communication technology, or may be an interface using other communication protocols, which is not limited herein.

The modem 110 and the application processor 130 communicate via a data transmission line, which may include, but is not limited to, PCIe, PCI, etc. The modem 110 may send downstream data to the applications processor 130 over a data transmission line, and the applications processor 130 may send upstream data to the modem 110 over a data transmission line.

In the related art, downlink data transmitted from a network side is transmitted to an application processor through a modem, and in order to avoid that the modem frequently transmits data to the application processor and increase power consumption of a device, the accumulated downlink data is usually transmitted to the application processor together when the downlink data received from the network side is accumulated to a certain amount. One embodiment is to set a fixed binding period in advance, for example, 5ms, 6ms, etc., which is usually set by a developer, and then the modem can send the downstream data to the application processor when the receiving time for receiving the downstream data reaches the binding period. However, in practice, it is found that the size of the data volume received by the modem in different binding periods is different, and if the data volume is too large, the modem cannot store the data when the time length for receiving the downlink data by the modem does not reach the binding period, which may affect the normal transmission of the data; if the data volume is small, the data transmission line is started to transmit a small amount of data, which results in waste of power consumption.

The method disclosed by the embodiment of the application can determine the time length corresponding to the current downlink data binding period according to the data throughput of the network end in the previous downlink data binding period, and then the modem can send the downlink data to the application processor through the data transmission line when the receiving time length of the downlink data meets the current downlink data binding period.

The embodiments of the present application may be applicable to Long Term Evolution (LTE) systems and subsequent evolution systems, such as fifth generation mobile communication technology (5 g), or other wireless communication systems using various radio access technologies, such as systems using access technologies of code division multiple access, frequency division multiple access, time division multiple access, orthogonal frequency division multiple access, single carrier frequency division multiple access, and the like, which is not limited herein.

Based on this, the data transmission method disclosed in the embodiment of the present application is described below.

Referring to fig. 2, fig. 2 is a schematic flow chart of a data transmission method disclosed in an embodiment of the present application, and when the method is applied to the scenario illustrated in fig. 1, the method may include the following steps:

202. the network 120 sends downstream data to the modem 110, and the modem 110 receives the downstream data.

In the embodiment of the present application, the network side 120 may transmit downstream data to the modem 110 through an air interface, and the downstream data may include various network data transmitted by the network side, including but not limited to video data, audio data, and the like, and is not limited herein.

204. If the receiving time length of the downlink data meets the time length of the current downlink data binding period, the modem 110 sends the downlink data to the application processor 130 through the data transmission line.

The modem 110 in the related art, after receiving the downstream data sent by the network 120, usually sends the downstream data directly to the application processor 130, which results in that the data transmission line is always in an operating state, thereby greatly increasing power consumption. In the embodiment of the present invention, after the downlink data is received cumulatively for a certain period of time, the modem 110 may send the cumulatively received downlink data to the application processor 130, so as to reduce the number of enabling times of the data transmission line, thereby reducing power consumption.

Alternatively, the cumulative receipt of downstream data by modem 110 may be equal to one downstream data bundling period. For example, if the current downstream data binding period is 5 seconds, the modem 110 may send the application processor the downstream data received within 5 seconds after cumulatively receiving the downstream data for 5 seconds.

In the embodiment of the present application, in order to further reduce the power consumption of enabling the data transmission line to transmit downstream data, the downstream data binding period of the modem 110 is improved. The current downlink data binding period may be determined according to the data throughput of the network 120 in the previous data binding period. It can be understood that the data throughputs of the network 120 in two adjacent binding periods are generally similar, so that the modem 110 can estimate the data throughput in the current binding period according to the data throughput of the network 120 in the previous binding period, and thus the modem 110 can adjust the duration of the current downstream binding period according to the estimated data amount. If the data throughput of the network 120 in the previous data binding period is large, the current downlink data binding period may be set to be long; conversely, if the data throughput of the network 120 in the last data binding period is smaller, the current downlink data binding period may be set to be shorter, so that the modem 110 may receive an appropriate amount of downlink data in the current downlink data binding period. Optionally, the current downlink data binding period may have a positive correlation with the data throughput of the network end in the previous data binding period.

Alternatively, the data transmission line may include an inactive state, an active state, and a low power consumption state. The data transmission line does not work when in a non-working state, works normally when in a working state, and only keeps normal work of part of necessary functions when in a low-power consumption state, namely, the data transmission line also works when in the low-power consumption state, but the power consumption is lower than that in the working state. Optionally, when the receiving time of the downlink data meets the time corresponding to the current downlink data binding period, if the data transmission line is in the non-working state, the data transmission line may be switched from the non-working state to the working state, and the downlink data is sent to the application processor through the data transmission line; optionally, if the data transmission line is in the low power consumption state, the data transmission line may be switched from the low power consumption state to the operating state, and downlink data is sent to the application processor through the data transmission line.

By implementing the method disclosed in each embodiment, the modem can receive the downlink data sent by the network side, and send the downlink data to the application processor through the data transmission line when the receiving time length of the downlink data meets the time length corresponding to the current downlink data binding period. It can be understood that the data throughput of the network end in two adjacent binding periods generally does not have a sudden change, that is, the data throughput of the network end in the current binding period can be roughly estimated through the data throughput of the network end in the last binding period, so that the current downlink data binding period can be determined according to the data throughput of the network end in the last binding period, and then the duration of the next binding period can be adjusted by the subsequent modem according to the estimated data throughput, so that the modem can start transmission after receiving downlink data with proper data volume in the current downlink data binding period, and the number of times of data transmission through the data transmission line can be reduced while normal data transmission is not affected, thereby reducing the power consumption of data transmission.

Referring to fig. 3, fig. 3 is a schematic flow chart of another data transmission method disclosed in the embodiment of the present application. Alternatively, the method may be applied to the scenario shown in fig. 1. For convenience of description, the modem shown below refers to the modem 110 in fig. 1, the network side refers to the network side 120 in fig. 1, and the application processor refers to the application processor 130 in fig. 1. The method may comprise the steps of:

302. the network terminal sends the downlink data to the modem, and the modem receives the downlink data sent by the network terminal.

In the embodiment of the present application, step 302 is similar to step 202, and is not repeated herein.

304. And if the receiving time length of the downlink data meets the time length of the current downlink data binding period, the modem sends the downlink data to the application processor through the data transmission line.

The current downlink data binding period is determined by the modem according to a first parameter, and the first parameter is used for indicating the data throughput of the network end in the last downlink data binding period. For example, the data throughput of the network end in the last downlink data binding period is 1Mbps, that is, data of 128B is transmitted in each transmission interval, and the duration of the current downlink data binding period may be 8 transmission intervals; if the data throughput of the network end in the last downlink data binding period is 0.5Mbps, that is, 64B data is transmitted in each transmission interval, the duration of the current downlink data binding period may be 4 transmission intervals.

Optionally, the modem may determine the duration of the current downlink data bundling period according to the data throughput of the network end in the last downlink data bundling period and the storage capacity of the memory included in the modem. For example, the duration of the current downlink data binding period may be a ratio between the storage capacity of the target memory and the data throughput of the network end in the last downlink data binding period.

For example, the data throughput of the network end in the last downlink data bundling period is 1Mbps, that is, data of 128B is transmitted in each transmission interval, and assuming that the storage capacity of the target memory is 1KB, the duration of the current downlink data bundling period may be 8 transmission intervals. Further, if one transmission interval is 1s, the duration of the current downlink data binding period may be 8s.

In an optional embodiment, the first parameter may include one or more of an error rate, a packet loss rate, and a jitter rate of the network in the last downlink data bundling period, and an air interface rate of the network in the last downlink data bundling period.

The network side transmits the uplink data to the network side at the air interface rate in the uplink data binding period; the error rate represents the accuracy of data transmission of the network end in the last downlink data binding period; the packet loss rate represents the ratio of data lost in the last downlink data binding period to the total data transmitted by the network end; the jitter rate represents the network speed delay condition of the network end.

Optionally, the first parameter may be an air interface rate and an error rate of the network end in the previous downlink data binding period, and the data throughput of the network end in the previous downlink data binding period may be a product between the air interface rate and the error rate of the network end in the previous downlink data binding period, that is, may be determined according to the throughput of valid data in the previous downlink data binding period. For example, if the air interface rate of the network end in the previous downlink data binding period is 2m/s and the error rate is 50%, the data throughput of the network end in the previous downlink data binding period may be 1m/s, and then the duration of the current downlink data binding period is determined in the same manner as described above, which is not described herein again.

By implementing the method, more accurate data throughput of the network end can be determined by combining parameters such as air interface rate, bit error rate, packet loss rate and jitter rate, so that the duration of the subsequently determined downlink data binding period is more matched with the actual data throughput of the network end, and therefore, the frequency of data transmission through a data transmission line can be reduced while normal data transmission is not influenced, and the power consumption of data transmission is further reduced.

306. The modem switches the data transmission line to a low power consumption state.

Specifically, the data transmission line may have three operating states, a low power consumption state (which may be referred to as a "stand by state" or an "L1.2 state"), and an operating state (which may be referred to as a "full active state" or an "L0 state"), where power consumption may reach a level of several hundred milliwatts when the data transmission line is in the operating state, and power consumption may be much less than several hundred milliwatts when the data transmission line is in the low power consumption state.

In addition, since the speed of switching the data transmission line from the low power consumption state to the operating state is faster than the speed of switching the data transmission line from the non-operating state to the operating state, for example, the time for switching the low power consumption state to the operating state is only about on the order of 8 to 12us, and the time for switching the data transmission line from the non-operating state to the operating state is on the order of 50 to 100us, the data transmission line is switched to the low power consumption state after completing the data transmission, and it is also possible to make the data transmission line quickly switched to the operating state while reducing the power consumption, so as to perform the data transmission task more quickly.

In another embodiment, the modem can also switch the data transmission line to an inactive state after completing the data transmission, and since the output transmission line is substantially non-power consuming when in the inactive state, power consumption can be minimized.

In an alternative embodiment, the data transmission line may be periodically switched between the operating state and the low power consumption state according to a preset operating mode or according to a switching instruction sent by the modem, where a total duration of one switching period may be N times a corresponding data transmission interval of the network, where N is a positive integer, for example, 3, 4, 5, and the like, which is not limited herein.

By implementing the method, the total duration of one switching period is set to be N times of the data transmission interval corresponding to the network end, so that the data transmission line can be started for data transmission at least once after N data transmission intervals, the starting times of the data transmission line can be reduced, and the power consumption of data transmission is reduced.

Optionally, in order to reduce the number of times of starting the data transmission line as much as possible, the starting time of the switching period of the data transmission line may be the same as the time of the downstream data bonding period.

In addition, in another embodiment, an uplink data binding period of the modem may be further set, where the application processor may send the uplink data to the modem through the data transmission line only when the duration of cumulative receiving of the uplink data reaches the uplink data binding period, and if the start and stop times of the uplink data binding period and the downlink data binding period are different, the modem needs to perform data transmission in different periods, so that the number of times of starting the data transmission line is increased, and therefore, in order to further reduce the number of times of starting the data transmission line to reduce power consumption, in this embodiment, the start time of the downlink data binding period may be the same as the start time of the uplink data binding period, that is, the switching period of the data transmission line, the start times of the uplink data binding period, and the start time of the downlink data binding period are all the same.

Further described with reference to fig. 4, fig. 4 is a timing chart of an example of starting times of a switching period, an upstream data bonding period, and a downstream data bonding period of a data transmission line disclosed in an embodiment of the present application. As can be seen from the figure, the start time T1 of the downlink data binding period is the same as the start time T1 of the uplink data binding period, so that the transmission processes of the uplink data and the downlink data can be overlapped as much as possible, as shown in fig. 4, the dotted line in the figure is a schematic diagram of a switching period of the data transmission line, in fig. 4, the switching period of the data transmission line includes two states, a working state and a low power consumption state, wherein the start time of the working state is the same as the start time of the uplink data binding period and the start time of the downlink data binding period, the end time of the working state is the maximum value of the end time of the working state in the uplink data binding period and the end time of the working state in the downlink data binding period, in fig. 4, the end time of the working state in the downlink data binding period is greater than the end time of the working state in the uplink data binding period, so that the end time of the working state in the downlink data binding period is the end time of the working state, and the data transmission line only needs to be in the time T1 to T2, so that the number of the data transmission line to be called can be reduced, thereby reducing the number of the data transmission line.

By implementing the method, the number of times of calling the data transmission line can be further reduced, and the power consumption in the data transmission process is further reduced.

By implementing the method disclosed by each embodiment, the current downlink data binding period can be determined according to the data throughput of the network end in the previous binding period, and then the subsequent modem can adjust the duration of the next binding period according to the estimated data throughput, so that the modem can start transmission after receiving downlink data with proper data volume in the current downlink data binding period, the normal transmission of the data can be not influenced, the frequency of transmitting the data through the data transmission line can be reduced, and the power consumption of data transmission can be further reduced; and, after the data transmission is completed, the data transmission line can be switched to a low power consumption state to reduce the power consumption of the data transmission line, so that the power consumption of the data transmission process can be further reduced; and, make the data transmission line can switch over to the working condition fast, in order to carry out the data transmission task more fast; and the data transmission line can be started for data transmission at least once after N data transmission intervals, so that the starting times of the data transmission line can be reduced, and the power consumption of data transmission is reduced.

Referring to fig. 5, fig. 5 is a schematic flowchart illustrating another data transmission method according to an embodiment of the present application. Alternatively, the method may be applied to the scenario shown in fig. 1. For convenience of description, the modem shown below refers to the modem 110 in fig. 1, the network side refers to the network side 120 in fig. 1, and the application processor refers to the application processor 130 in fig. 1. The method may comprise the steps of:

502. the network terminal sends the downlink data to the modem, and the modem receives the downlink data sent by the network terminal.

In the embodiment of the present application, step 502 is similar to step 202, and is not described herein again.

504. The modem stores the downstream data in the first memory and/or the second memory.

When the modem receives the downstream data, the downstream data is stored in the memory. In this embodiment, the memory of the modem may include a first memory and a second memory, where the power consumption of the first memory is lower than that of the second memory, and optionally, the first memory may include a static random access memory, and the second memory may include a double-rate synchronous random access memory, although the first memory and the second memory may be other types of memories, which is not limited herein. The example in which the modem stores the downstream data in the first memory is illustrated in fig. 5.

Optionally, there may be one or more first memories and one or more second memories, and when there are a plurality of second memories, the kinds of the respective second memories may be different or the same, and are not limited herein.

Alternatively, the storage capacity of the first memory may be determined according to the historical data throughput of the network side in the downlink data binding period.

As an example, please refer to fig. 6, fig. 6 is a schematic diagram illustrating a relationship between storage capacities of a first memory and a second memory and a transmission rate of downlink data according to an embodiment of the present application, where the larger the transmission rate of the downlink data is, the larger the data throughput of a network side is, and therefore, the transmission rate of the downlink data can be understood as the throughput of the network side.

As shown in fig. 6, the power consumption of the first memory 610 increases as the transmission rate of the downstream data increases, and similarly, the power consumption of the second memory 620 and the data transmission line 730 also increases as the transmission rate of the downstream data increases, respectively. After the label "2" in fig. 6, the implemented power consumption of the second memory is greater than or equal to the real-time power of the data transmission line (i.e. the part after the label "2" in fig. 6), which indicates that the transmission rate of the downlink data is faster at this time, the data transmission line 730 is always in the working state to ensure that the downlink data can be transmitted to the application processor in time, and at this time, the power consumption of the data transmission line 630 is kept at a fixed size. When the real-time power consumption of the second memory is smaller than the real-time power consumption of the data transmission line before the label "2" in fig. 6 (i.e., the part before the label "2" in fig. 7), which indicates that the transmission rate of the downstream data is still slower at this time, the modem may control the data transmission line to be periodically switched between the operating state and the low power consumption state, that is, the data transmission line 630 is periodically in the operating state, and therefore, the power consumption of the modem is related to the power consumption of the data transmission line and the power consumption of the memory of the modem, respectively. Then in this case, if the power consumption of the modem is further reduced, the power consumption of the memory can be reduced.

In addition, as can be seen from fig. 6, when the throughput is lower than a certain value, for example, the position of the label "1" in fig. 6, as long as the first memory can be selected with a suitable size, all the downstream data can be processed on the first memory, and the power consumption of the modem can be further reduced because the power consumption of the first memory is lower.

Therefore, according to the above conclusion, in the embodiment of the present application, the storage capacity of the first memory is associated with the data throughput in the downstream data binding period of the network side. For example, the technician may determine the throughput of the network during the downlink data binding period, or the technician may determine the throughput of the network during the downlink data binding period in different usage scenarios, that is, the storage capacity of the first storage is different in different usage scenarios. For example, the storage capacity of the first memory in a scene involving more video data storage is larger than that in a scene involving more text data storage, but other size relationships are certainly possible, and the foregoing example is only used to express that the storage capacity of the first memory in different scenes is different, and is not used to limit the correspondence relationship between the storage capacity and the scene.

Through the scheme, the first memory is enough to store the downlink data sent by the network end in the current downlink data binding period under most conditions, and a second memory with higher power consumption is not required to be called, so that the power consumption in the data transmission process can be reduced.

Optionally, after the downlink data stored in the first memory is transmitted, the corresponding target storage space of the transmitted downlink data in the first memory may be released, and then the downlink data is reused for storing the subsequently received downlink data. For the modem, the adjustment proportion can be determined according to the release speed of the target memory; and determining the storage capacity of the first storage according to the data throughput of the network end in the last downlink data binding period and the adjustment proportion.

Optionally, the modem determines a temporary storage capacity according to data throughput of the network end in the previous downlink data binding period, and takes a product of the temporary storage capacity and the adjustment ratio as the storage capacity of the first storage.

For example, if the temporary storage capacity determined by the modem according to the data throughput of the network in the last downstream data binding period is 1K, and the adjustment ratio is determined to be 50% according to the release speed of the target memory, it may be determined that the storage capacity of the first memory is 1k × 50% =0.5K.

By implementing the method, considering that the corresponding target storage space in the first memory can be released and then reused for storing the subsequently received downlink data, the first memory can be further reduced, so that the cost and the internal space of the modem can be saved.

In the embodiment of the present application, the modem determining the storage location of the downlink data may include, but is not limited to, the following three ways:

in a first manner, after receiving downlink data sent by a network, a modem may determine a storage location of the downlink data according to a data size, for example, if the data size of the downlink data is less than or equal to a storage capacity of a first memory, the modem may preferentially store the downlink data in the first memory with lower power consumption, thereby reducing power consumption in a data transmission process; if the data volume of the downstream data is larger than the storage capacity of the first memory, the modem can store the downstream data into the first memory and the second memory to ensure the normal storage of the downstream data.

Referring to fig. 7, fig. 7 is a schematic structural diagram of a modem according to an embodiment of the present disclosure. Optionally, after receiving the downstream data sent by the network side, the modem may directly call the first memory 720 through the security driver 710, and store the downstream data in the first memory 720. Optionally, to improve the security of data transmission, the downlink data sent by the network end may be in an encrypted state, and after receiving the downlink data sent by the network end, the modem may decrypt the downlink data through the security driver 710, and store the decrypted downlink data in the first memory 720 and/or the second memory 730.

Optionally, the modem may also release a target storage space in the first memory 720 through the security driver 710, where the target storage space is a corresponding storage space in the first memory 720 for the downlink data that has completed transmission.

Alternatively, the modem may release the target memory space in the first memory 720 through the security driver 710 after completing the transmission of the downstream data. That is, the modem may perform the release of the storage space once through the security driver 710 after completing all the downlink data, so that the number of times of performing the release of the storage space by the security driver 710 may be reduced, and further, the power consumption may be reduced.

In another embodiment, the modem may release the target memory space in the first memory 720 through the security driver 710 after transmitting M units of downlink data during the transmission of the downlink data, where M is a positive integer. For example, after the modem has transmitted 3 units of downstream data, the modem may preferentially release the storage space corresponding to the 3 units of downstream data in the first memory 720. By implementing the method, the utilization rate of the storage space of the first memory can be improved by increasing the times of storage space release, so that more downlink data can be stored in the first memory, and the times of calling the second memory with higher power consumption can be reduced.

The security driver (security driver) is a driver disposed inside the modem, and may be used to call and release the storage space of the first memory, decrypt the received downlink data, and the like, which is not limited herein.

By implementing the method, the modem can directly call and release the first memory through the internal safety drive, so that the use and the storage space release of the first memory are faster and more flexible, and the data transmission speed is improved; in addition, since the storage space of the first memory can be quickly released, the storage capacity of the first memory can be set smaller, so that the modem can be designed in a small size even at a low cost.

In a second mode, after receiving the downlink data sent by the network side, the modem may preferentially store the downlink data in the first memory until the first memory is in a saturated state, and store the remaining part of the downlink data in the second memory, where the remaining part of the downlink data is data that cannot be stored in the first memory. The saturation state refers to a state in which the first memory has no free memory space.

By implementing the method, the modem can preferentially store the downlink data into the first memory with lower power consumption so as to reduce the power consumption. However, since the first memory has a higher cost and a larger area, the storage capacity of the first memory is usually set to a reasonable value without being too large in order to save cost and save the internal space of the modem as much as possible. In contrast, if the amount of the downlink data is larger than the storage capacity of the first memory, the modem can store the data that cannot be stored in the first memory into the second memory, which has a smaller area and a lower cost, so that the modem can be designed to be smaller while saving costs. In addition, since the power consumption of the second storage is in positive correlation with the amount of the stored data, the use of the second storage for storing a small amount of downstream data does not consume excessive power.

Optionally, the second memory may be used not only for storing downstream data, but also for storing other data (e.g. upstream data, system data, etc.), and in order to facilitate the modem to uniformly manage the storage space of the second memory, the invoking and releasing of the second memory may be controlled by a system manager (e.g. a central processor) of the modem. In contrast, when the first memory is in a saturated state and the second memory is required to be used for storing data which cannot be stored in the first memory, the modem can apply to a system manager of the modem for calling the second memory through the secure driver; the system manager feeds back an instruction for agreeing to call to the security driver when determining that the second memory still has a free memory space; the security driver, in turn, may store the remaining portion of the data in the second memory upon determining that the system manager approves the invocation of the second memory.

Optionally, the security driver may further apply for releasing the storage space of the second memory to the system manager when the transmission of the downstream data stored in the second memory is completed, so that the storage space of the second memory may be quickly released to be reused.

By implementing the method, the storage space of the second memory can be uniformly called and released through the system manager, so that the second memory cannot generate conflict when storing downlink data and other data, and the second memory can be more efficiently utilized to store more kinds of data.

In a third mode, after receiving the downlink data sent by the network side, the modem can also store the downlink data into the first memory and/or the second memory according to the data type corresponding to the downlink data.

Optionally, the data type corresponding to the downlink data may include, but is not limited to, video data, audio data, image data, and the like. It is to be understood that the data size corresponding to different data types is usually different; for example, the data volume of the video data is usually large, so the first memory and the second memory can be called simultaneously for storage; and the data volume of the image data is usually small, only the first memory or the second memory can be called for storage. Optionally, if the data type corresponding to the downlink data is video data, the downlink data may be stored in the first memory and the second memory; if the data type corresponding to the downlink data is image data, the downlink data can be stored in the first memory or the second memory.

In another embodiment, if the data type corresponding to the downlink data is the first type, the downlink data is stored in the first memory, wherein the data amount of the downlink data belonging to the first type is less than or equal to the storage capacity of the first memory.

If the data type corresponding to the downlink data is the second type, the downlink data can be preferentially stored in the first memory until the first memory is in a saturated state, and the remaining data in the downlink data is stored in the second memory, wherein the remaining data is data which is not stored in the first memory.

Optionally, the data amount of the first type of downlink data and the data amount of the second type of downlink data may be determined according to historical experience values, or may be set by a developer according to development experience, which is not limited herein.

By implementing the method, the modem can determine the approximate data volume of the downstream data according to the data type of the received downstream data, so that the first memory and/or the second memory can be called more flexibly for memory, and the first memory with lower power consumption can be adopted as far as possible while the memory requirement is met, so that the power consumption is reduced.

506. And if the receiving time length of the downlink data meets the time length of the current downlink data binding period, the modem sends the downlink data to the application processor through the data transmission line.

In an embodiment, before sending the downlink data to the application processor through the data transmission line if the receiving duration of the downlink data meets the duration of the current downlink data binding period, the modem may determine the current downlink data binding period according to the data throughput of the network end in the last downlink data binding period. The process is similar to step 204 or step 304 and will not be described herein.

In the embodiment of the application, the modem can acquire the current real-time point, and if the real-time point is in a busy period of data transmission, the time length corresponding to the current downlink data binding period is increased by a first time length; and if the real-time point is in the idle period of data transmission, reducing the time length corresponding to the current downlink data binding period by a second time length.

The first time period and the second time period may be set by a developer according to a great amount of development experience, and typical values may include 1s, 2s, and the like, which is not limited herein.

Optionally, the busy period of data transmission may include a non-rest time period, for example: 8 am to 11 pm; for example, the time from 7 am to 10 pm is not limited herein. The data transmission idle time point may include a rest time point, for example: 11 pm to 8 am on the following day; another example is: 10 pm to 7 am on the next day without limitation.

By implementing the method, the adjusting demodulator can adaptively adjust the time length of the current downlink data binding period according to whether the current time point is in the period of busy data transmission, so as to avoid that the modem cannot store data when the time length for receiving the downlink data does not reach the binding period, and further normal transmission of the data is influenced; in addition, the time length corresponding to the current downlink data binding period can be adaptively reduced when the current time point is in the idle data transmission period, so that the condition that the modem only receives a small amount of data when the time length for receiving the downlink data reaches the binding period, and the power consumption is wasted when the data transmission line is started to transmit the small amount of data at the time is avoided.

In another embodiment, the modem may determine a target operator to which downlink data transmitted by the network in the last downlink data binding period belongs; if the target operator is an operator of a video type (for example, an operator of short video software and an operator of video-on-demand software), increasing a time length corresponding to the current downlink data binding period by a first time length; if the target operator is an operator of the communication type (for example, an operator of chat software, an operator of mail software), reducing the time length corresponding to the current downlink data binding period by a second time length.

By implementing the method, the modem can also adaptively adjust the time length of the current downlink data binding period according to the type of an operator, so that the subsequent modem can start transmission after receiving downlink data with proper data volume in the current downlink data binding period, thereby reducing the frequency of transmitting data through the data transmission line while not influencing the normal transmission of the data, and further reducing the power consumption of data transmission.

By implementing the methods disclosed in the above embodiments, on the first hand, a current downlink data binding period can be determined according to the data throughput of a network end in a previous binding period, and then a subsequent modem can adjust the duration of a next binding period according to the estimated data throughput, so that the modem can start transmission after receiving downlink data with a proper data amount in the current downlink data binding period, and the number of times of data transmission through a data transmission line can be reduced while normal data transmission is not influenced, thereby reducing the power consumption of data transmission;

in the second aspect, the modem can directly call and release the first memory through the internal safety drive, so that the use and the storage space release of the first memory are faster and more flexible, and the data transmission speed is improved; in addition, since the storage space of the first memory can be quickly released, the storage capacity of the first memory can be set smaller, so that the cost can be saved and the miniaturization design of the modem can be realized;

in a third aspect, the downlink data may be preferentially stored in the first memory with lower power consumption, so as to reduce power consumption; and the data which can not be stored in the first memory can be stored in a second memory with lower cost and smaller area, thereby saving the cost and realizing the miniaturization design of the modem; the storage space of the second memory can be uniformly called and released through the system manager, so that the second memory cannot generate conflict when storing downlink data and other data, and the second memory can be used for storing more kinds of data more efficiently;

in the fourth aspect, the approximate data size of the downlink data can be determined according to the data type of the received downlink data, so that the first memory and/or the second memory can be called more flexibly for storing, and the first memory with lower power consumption can be adopted as far as possible while the storage requirement is met, so that the power consumption is reduced.

Referring to fig. 8, fig. 8 is a schematic structural diagram of a data transmission device according to an embodiment of the present disclosure. Alternatively, the device may be applied to a modem. The apparatus may comprise a receiving unit 802 and a transmitting unit 804, wherein:

a receiving unit 802, configured to receive downlink data sent by a network;

a transmission unit 804, configured to send downlink data to the application processor through the data transmission line when the receiving time of the downlink data meets the time of the current downlink data binding period, where the current downlink data binding period is determined according to a first parameter, and the first parameter is used to indicate the data throughput of the network end in the previous downlink data binding period.

By implementing the device, the modem can receive the downlink data sent by the network terminal and send the downlink data to the application processor through the data transmission line when the receiving time length of the downlink data meets the time length corresponding to the current downlink data binding period. It can be understood that the data throughput of the network end in two adjacent binding periods usually does not have a sudden change, that is, the data throughput of the network end in the current binding period can be roughly estimated through the data throughput of the network end in the last binding period, for this reason, the current downlink data binding period can be determined according to the data throughput of the network end in the last binding period, and then the time length of the next binding period can be adjusted by the subsequent modem according to the estimated data throughput, so that the modem can start transmission after receiving downlink data with a proper data volume in the current downlink data binding period, and the number of times of data transmission through the data transmission line can be reduced while normal data transmission is not affected, thereby reducing the power consumption of data transmission.

As an optional implementation manner, the first parameter may include one or more of an error rate, a packet loss rate, and a jitter rate of the network end in the last downlink data binding period, and an air interface rate of the network end in the last downlink data binding period.

By implementing the device, more accurate data throughput of the network end can be determined by combining parameters such as air interface rate, bit error rate, packet loss rate and jitter rate, so that the duration of the subsequently determined downlink data binding period is more matched with the actual data throughput of the network end, the number of times of data transmission through the data transmission line can be reduced while normal data transmission is not influenced, and the power consumption of data transmission is further reduced.

As an alternative embodiment, the apparatus shown in fig. 8 may further include a switching unit, not shown, wherein:

and the switching unit is used for switching the data transmission line to a low power consumption state, and the power consumption of the low power consumption state is less than that of the working state of the data transmission line.

By implementing the device, the data transmission line can be switched to the low power consumption state after the data transmission is finished, so that the power consumption of the data transmission line is reduced, and the power consumption of the data transmission process can be further reduced. In addition, since the speed of switching the data transmission line from the low power consumption state to the operating state is faster than the speed of switching from the non-operating state to the operating state, switching the data transmission line to the low power consumption state after completing the data transmission can also allow the data transmission line to be quickly switched to the operating state while reducing power consumption, so as to perform the data transmission task more quickly.

As an optional implementation manner, the data transmission line is periodically switched between the operating state and the low power consumption state, the total duration of one switching period is N times of the data transmission interval corresponding to the network, and N is a positive integer.

By implementing the device, the total duration of one switching period is set to be N times of the data transmission interval corresponding to the network end, so that the data transmission line can be started for data transmission at least once after N data transmission intervals, the starting times of the data transmission line can be reduced, and the power consumption of data transmission is reduced.

As an optional implementation manner, the starting time of the switching period is the same as the starting time of the downlink data binding period.

By implementing the device, the number of times of calling the data transmission line can be further reduced, and the power consumption in the data transmission process is further reduced.

As an alternative embodiment, the apparatus shown in fig. 8 further includes a first storage unit, not shown, wherein:

the modem comprises a first memory and a second memory, and the power consumption of the first memory is lower than that of the second memory.

By implementing the device, the downlink data can be preferentially stored in the first memory with lower power consumption, so that the power consumption in the data transmission process is reduced.

As an optional implementation manner, the first storage unit is further configured to, after receiving the downlink data sent by the network side, store the downlink data into the first memory if a data amount of the downlink data is less than or equal to a storage capacity of the first memory.

As an alternative implementation, the first memory may be called by a security driver of the modem, and the apparatus shown in fig. 8 further includes a release unit, not shown, where:

and the release unit is used for releasing a target storage space in the first memory through the security drive, wherein the target storage space is a storage space corresponding to the transmitted downlink data in the first memory.

By implementing the device, the modem can directly call and release the first memory through the internal safety drive, so that the use and the storage space release of the first memory are faster and more flexible, and the data transmission speed is improved; in addition, since the storage space of the first memory can be quickly released, the storage capacity of the first memory can be set smaller, so that the modem can be designed in a small size even at a low cost.

As an alternative embodiment, the apparatus shown in fig. 8 further includes a second storage unit, not shown, wherein:

the modem comprises a first memory and a second memory, wherein the first memory is used for storing downlink data in a first memory in a first mode until the first memory is in a saturated state, the second memory is used for storing the downlink data in the first memory preferentially after receiving the downlink data sent by a network end until the first memory is in the saturated state, the modem comprises the first memory and the second memory, the power consumption of the first memory is lower than that of the second memory, and the remaining data is data which is not stored in the first memory.

By implementing the device, the modem can preferentially store the downlink data into the first memory with lower power consumption so as to reduce the power consumption. However, since the first memory has a higher cost and a larger area, the storage capacity of the first memory is usually set to a reasonable value without being too large in order to save cost and save the internal space of the modem as much as possible. In contrast, if the amount of the downlink data is larger than the storage capacity of the first memory, the modem may store the data that cannot be stored in the first memory into the second memory, which has a smaller area and a lower cost, so that the modem may be designed to be smaller and to be more compact while saving costs. In addition, since the power consumption of the second storage is in positive correlation with the amount of the stored data, the use of the second storage for storing a small amount of downstream data does not consume excessive power.

As an optional embodiment, the second storage unit is further configured to apply for calling the second storage from a system manager of the modem through the secure driver; and upon determining that the system manager agrees to invoke the second memory, storing the remaining portion of the data to the second memory.

By implementing the device, the system manager can uniformly call and release the storage space of the second memory, so that the second memory does not generate conflict when storing the downlink data and other data, and the second memory can be used for storing more kinds of data more efficiently.

As an alternative embodiment, the apparatus shown in fig. 8 further includes a third storage unit, not shown, wherein:

and the modem comprises a first memory and a second memory, and the power consumption of the first memory is lower than that of the second memory.

By implementing the device, the modem can determine the approximate data volume of the downstream data according to the data type of the received downstream data, so that the first memory and/or the second memory can be called more flexibly for memory, and the first memory with lower power consumption can be adopted as far as possible while the memory requirement is met, so that the power consumption is reduced.

As an alternative embodiment, the first memory comprises a static random access memory and the second memory comprises a double rate synchronous random access memory.

As an alternative implementation, the storage capacity of the first storage is determined according to the historical data throughput of the network in the downlink data binding period.

By implementing the device, under most conditions, the first memory is enough to store the downlink data sent by the network end in the current downlink data binding period, and a second memory with higher power consumption is not required to be called, so that the power consumption in the data transmission process can be reduced.
