Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a control method and a control device.

Background

With the continuous development of communication technology, the 5G technology is also becoming more and more perfect. In some newly-built indoor scene environments, since 4G equipment is not built, 5G equipment also needs to be deployed at the same time. To reduce costs, communication operators can use 4G/5G multi-mode digitizing room distribution equipment directly in newly built indoor scenarios. The 4G/5G multi-mode digital room division equipment can provide 4G data and 5G data for the terminal equipment.

The 4G/5G multi-mode digital room branch equipment comprises baseband equipment, convergence equipment and remote equipment. A plurality of remote devices may be connected to the aggregation device. Since the coverage area of the remote devices is small, a large number of remote devices need to be installed when the newly built room scene is large. Since the remote device belongs to the active device. Thus, when a large number of remote devices are operating, a large amount of power is consumed. Therefore, how to reduce the energy consumption of the equipment becomes a problem which needs to be solved urgently.

As shown in fig. 7, the control method may include:

step 701, the remote device obtains first IQ data within a preset time period and a bit width corresponding to the first IQ data.

Wherein the remote device may be the remote device of fig. 1. The preset period may include a plurality of slots, and the time interval between each slot is the same. The preset time period and the time interval between the time slots may be set as needed, for example, the preset time period may be 1 minute, 5 minutes, 1 hour. The time interval between each slot may be 0.5 milliseconds (ms), 1ms, etc., without limitation.

It should be noted that, the obtaining, by the remote device, the first 1Q data in the preset time period may refer to the obtaining, by the remote device, the first IQ data of each time slot in a plurality of time slots in the preset time period.

The IQ data may include I-path data and Q-path data, and may refer to that the remote device modulates/processes data from the aggregation device or the terminal device into two paths of data. I.e., I-way data and Q-way data. In particular, reference may be made to the prior art.

In this embodiment, the first IQ data may refer to IQ data corresponding to data of the first network type. For example, the data of the first network format may be 5G data. Of course, the data of the first network system may also be other data, for example, may also be 6G data, without limitation.

The bit width corresponding to the first IQ data may refer to a data amount of the first IQ data transmitted by the remote device at a single time. The bit width corresponding to the first IQ data is preset. For example, it may be 15 bits (bits).

In a possible implementation manner, the remote device may obtain data of the first network system through interaction with the aggregation device or the terminal device, and process the data of the first network system to obtain the first IQ data.

The interaction process between the remote device and the sink device may be referred to as a downlink data transmission process. The interaction process between the remote device and the terminal device may be referred to as an uplink data transmission process. Subsequently, a downlink data transmission process and an uplink data transmission process will be described, which are not described herein again.

Step 702, the remote device calculates a first average output power of the remote device within a preset time according to the first IQ data and a bit width corresponding to the first IQ data.

Wherein the first average output power may be used to characterize a load condition of a first communication module of the remote device.

In a possible implementation manner, the remote device may determine an output power of each of a plurality of time slots at a preset time, and calculate the first average output power according to the output powers of the plurality of time slots.

The output power of a time slot is calculated according to the first IQ data in the time slot and the corresponding bit width.

In one example, the remote device may calculate the output power for one slot according to equation one.

Wherein, in the above formula I, P _DL First IQ data output power, m, representing the time slot ₁ Data amount, n, representing first IQ data ₁ Representing a bit width, I, of the first IQ data _i Data amount of I-path data, Q, representing first IQ data _i The data amount of the Q-path data representing the first IQ data.

In yet another example, the remote device may calculate the first average output power of the remote device within the preset time according to formula two.

Wherein, in the above formula II, P ₁ Represents the average output power of the first IQ data within a preset time period, and T represents the preset time period.

And 703, under the condition that the first average output power is smaller than the first preset power, the remote device closes the first communication module and controls the second communication module to be in an open state.

The first preset power may be set as needed, and the application is not limited.

The method for closing the first communication module and controlling the second communication module to be in the open state by the remote device may refer to the above description, and is not repeated herein.

Based on the technical scheme provided by the application, the average output power of the first IQ data of the remote device within the preset time period can reflect the load condition of the first communication module of the remote device. When the average output power of the first IQ data of the remote device within the preset time period is smaller than the preset threshold, it indicates that the load of the first communication module of the remote device is low. In case the load of the first communication module is low, the remote device may determine to switch off the first communication module, so that the energy consumption of the remote device may be reduced.

In a possible implementation manner, as shown in fig. 8, the method provided in the embodiment of the present application may further include:

step 801, the remote device acquires second IQ data within a preset time period and a bit width corresponding to the second IQ data.

The second IQ data bit width may refer to a data amount of the remote device transmitting the second IQ data at a single time. The bit width corresponding to the second IQ data is preset. For example, it may be 15 bits (bits).

And step 802, the remote device calculates a second average output power of the remote device within a preset time according to the second IQ data and a bit width corresponding to the second IQ data.

Wherein the second average output power may be used to characterize a load condition of a second communication module of the remote device.

In a possible implementation manner, the remote device may determine the output power of each of a plurality of time slots at a preset time, and calculate the second average output power according to the output powers of the plurality of time slots.

And calculating the output power of one time slot according to the second IQ data in the time slot and the corresponding bit width.

In one example, the remote device may calculate the output power for one slot according to equation three below.

Wherein, in the formula III, P _2DL Second IQ data output power, m, representing the time slot ₂ Data amount, n, representing second IQ data ₂ Bit width, I, of second IQ data _i Data amount of I-path data, Q, representing second IQ data _i The data amount of the Q-path data representing the second IQ data.

In yet another example, the remote device may calculate the second average output power of the remote device within the preset time according to the following formula four.

Wherein, in the above formula four, P ₂ Represents the average output power of the second IQ data within a preset time period, and T represents the preset time period.

Step 803, the remote device turns on the first communication module when the second average output power is greater than or equal to the second preset power and the first average output power is less than the first preset power.

The second preset power can be set according to the requirement, and the application is not limited.

Based on the possible implementation manner, when the remote device determines that the load of the second communication module is higher, the first communication module may be started to carry a part of the service of the terminal device. Thereby, the stress of the second communication module is relieved to a certain extent. In another possible implementation manner, the method provided in the embodiment of the present application may further include: before the remote device closes the first communication module, if the first communication module is in a connection state with the terminal, the terminal is switched to the second communication module.

Based on the technical scheme of the application, the remote device switches the terminal to the second communication module under the condition that the load of the first communication module is small, and the communication of the terminal cannot be influenced.

The following describes the above related downlink data transmission process and uplink data transmission process by taking the first IQ data as 5G IQ data and the second IQ data as 4G IQ data as an example:

first, as shown in fig. 9, the downlink data transmission process may include steps 901 to 907:

the downlink is a link for the baseband device to transmit data to the remote device.

Step 901, the baseband device sends data to the convergence device. Accordingly, the sink device receives data from the baseband device.

The baseband device may be the baseband device 110 in fig. 1. The aggregation device may be aggregation device 120 of fig. 1.

Wherein the data may include multiple types of data. For example, 4G data and 5G data may be included.

Step 902, the aggregation device processes the data to obtain processed data. The processed data may include 5G IQ data and 4G IQ data. The processing of data by the aggregation device may include mapping and framing.

The following describes the mapping process and framing process:

1. and (5) mapping processing. The mapping process may refer to the sink device mapping data to IQ data.

The IQ data comprises I path data and Q path data. For example, when the data includes 4G data and 5G data, the aggregation device may map the 4G data to 4G IQ data, and map the 5G data to 5G IQ data.

It should be noted that the convergence device performs data transmission with the baseband device through the CPRI interface. Since the CPRI interface is defined by the standard to map data into a complex form, i.e., an I + iQ form. That is, the I-way data and the Q-way data are complex forms of data.

2. And (5) framing processing. The framing process may refer to CPRI framing. In particular, it is not described in detail with reference to the prior art.

Step 903, the sink device sends the processed data to the remote device. Accordingly, the remote device receives the processed data from the aggregation device.

The remote device may be the remote device 130 in fig. 1.

Specifically, the processor in the aggregation device duplicates the 4G IQ data and the 5G IQ data, and sends the duplicated 4G IQ data and 5G IQ data to each time domain IQ data processing module. And the time domain IQ data processing module sends the processed 4G IQ data and 5G IQ data to a CPRI framing/de-framing module, and the processed 4G IQ data and 5G IQ data are sent to each remote device after CPRI framing.

Step 904, the remote device calculates the output power of the 4G IQ data of each time slot within a preset time, and calculates the average output power of the 4G IQ data of the remote device within a preset time period according to the output power of the 4G IQ data within a plurality of time slots.

Step 905, the remote device calculates the output power of the 5G IQ data of each time slot within a preset time, and calculates the average output power of the 5G IQ data of the remote device within a preset time period according to the output power of the 5G IQ data within a plurality of time slots.

Specifically, step 904 and step 905 may refer to the description of step 702, and are not repeated herein.

Step 906, if the average output power of the 5G IQ data is smaller than the first power threshold, the remote device turns off the 5G communication module, and controls the 4G communication module to be in an on state.

Step 907, before closing the 5G communication module, if the 5G communication module is connected with a terminal device, the remote device switches the terminal device to the 4G communication module.

Further, after the remote device turns off the 5G communication module, the method may further include:

step 908, the remote device starts the 5G communication module when the average output power of the 4G IQ data is greater than or equal to the second preset power and the average output power of the 5G IQ data is less than the first preset power.

And step 909, when the remote device starts the 5G communication module, the remote device sends a first notification message to the baseband device through the convergence device.

The first notification message is used for notifying the 5G communication module of the remote device to be started. For example, the first notification message may be an OAM control message.

Secondly, as shown in fig. 10, the uplink data transmission process may include steps 1001 to 1009:

the uplink is a link for the remote device to send data to the baseband device.

Step 1001, the remote device maps the 4G data to 4G IQ data, and the 5G data to 5G IQ data.

The data may include 4G data and 5G data, among others. The data may be data from a terminal.

In one example, the terminal may generate and transmit data to the remote device when the terminal responds to user action. Accordingly, the remote device receives data from the terminal.

Specifically, the remote device may transmit the received 4G data and 5G data to the digital intermediate frequency data processing module through the radio frequency module, and the data intermediate frequency processing module may map the 4G data to 4G IQ data and map the 5G data to 5G IQ data.

Step 1002, the remote device sends 4G IQ data and 5G IQ data to the aggregation device. Correspondingly, the convergence device receives the 4G IQ data and the 5G IQ data from the remote device.

Specifically, the remote device sends the 4G IQ data and the 5G IQ data to the aggregation device through the CPRI framing/deframing module, and after receiving the data of each remote device, the CPRI deframing module of the aggregation device may send the data to the time domain IQ data processing module. The time domain IQ processing module can perform time-frequency conversion on the data to obtain 4G IQ data and 5G IQ data after time-frequency conversion.

In an example, each time domain IQ data processing module of the aggregation device sends the processed 4G IQ data and 5G IQ data to the frequency domain IQ data processing module for uplink channel merging and then time-frequency conversion.

Step 1003, the convergence device sends the time-frequency-converted 4G IQ data and 5G IQ data to the baseband device. Correspondingly, the baseband equipment receives the 4G IQ data and the 5G IQ data from the convergence equipment after time-frequency conversion.

Step 1004, the remote device calculates 4G IQ data of each time slot within a preset time, and calculates an average output power of the 4G IQ data of the remote device within a preset time period according to the output power of the 4G IQ data within a plurality of time slots.

Step 1005, the remote device calculates the output power of the 5G IQ data of each time slot within a preset time, and calculates the average output power of the 5G IQ data of the remote device within a preset time period according to the output power of the 5G IQ data within a plurality of time slots.

Specifically, step 1004 and step 1005 may refer to the description of step 702, and are not repeated.

Step 1006, if the average output power of the 5G IQ data is smaller than the first power threshold, the remote device closes the 5G communication module, and controls the 4G communication module to be in an open state.

Before step 1006, the method may further include:

step 1007, before closing the 5G communication module, if the 5G communication module is connected with a terminal device, the remote device switches the terminal device to the 4G communication module.

step 1008, the remote device starts the 5G communication module when the average output power of the 4G IQ data is greater than or equal to the second preset power and the average output power of the 5G IQ data is less than the first preset power.

And step 1009, when the far-end device opens the 5G communication module, sending a second notification message to the baseband device through the convergence device.

And the second notification message is used for notifying the 5G communication module of the remote equipment to be started. For example, the second notification message may be an OAM control message.
