Referring to fig. 1, an embodiment of the present invention provides a method for co-locating 4G and 5G, which is applied to a 5G base station, and the processing procedure of the method is as follows.

Step 101: acquiring first service data belonging to the 4G service and second service data belonging to the 5G service from the received original service data; the first service data and the second service data are combined in the original service data in a preset combination mode.

In the embodiment provided by the invention, the 5G Base station can receive the data of the 4G service and the data of the 5G service at the same time, for example, in an integrated Active antenna Unit (Active AntennaUnit, AAU) of the 5G Base station, one part of antennas is used for receiving the data of the 4G service, the other part of antennas is used for receiving the data of the 5G service, the data belonging to the 4G service and the data belonging to the 5G service are combined together in an AAU according to a preset combination mode and encapsulated into the original service data corresponding to the 5G radio frame, and the original service data is sent to a baseband processing Unit (Base Band Unit, BBU). After receiving the original data, the BBU acquires first service data belonging to the 4G service and second service data belonging to the 5G service from the BBU in a preset combination mode through the 5G baseband board.

The preset combination mode may be, for example, that the resource ratio of the 4G service in a 5G radio frame is 1/3, 2/3 or 3/3, that is, the 4G service may occupy 1/3, 2/3 or 3/3 of the resources in the 5G radio frame, so that in a 5G radio frame, the combination mode of the data of the 4G service and the 5G service data may be as follows: 1:2 or 2:1, or data of the full 4G service (e.g. when the 5G base station is initially established, there are no 5G users in its coverage area). The determining of the preset combination mode may be determined after counting the number of the 4G users and the 5G users in the range governed by the 5G base station.

For example, please refer to fig. 2, which is a schematic diagram illustrating a combination of data of a 4G service and data belonging to a 5G service in a preset combination manner in a 5G radio frame according to an embodiment of the present invention. Assuming that the ratio of the preset combining manner is 1:2, as shown in fig. 2, each 5G radio frame (assuming that the transmission period is 10 ms) includes 256 supergroups (supergroups), each supergroup includes 150 fragments (chips), so that a total of 150×256=38400 chips in one 5G radio frame, in the case that the 4G service occupies 1/3 of the 5G radio frame resources, 1 chip is used to transmit data of the 4G service in every 3 chips, and 2 chips are used to transmit data of the 5G service (as shown in fig. 2). Similarly, in the case that the 4G service occupies 2/3 of the 5G radio frame resource, 2 chips are used to transmit the data of the 4G service in every 3 chips, and 1 chip is used to transmit the data of the 5G service.

For uplink data (i.e., original service data) received by the 5G base station, the following processing method is adopted:

first, first service data belonging to a 4G service and second service data belonging to a 5G service are acquired from received original service data, and the specific implementation manner may be:

according to a preset combination mode, respectively determining a first position and a second position of service data of the 4G service and the 5G service stored in original service data; starting from a first position in the original service data, acquiring fragment data comprising a first number as first service data; starting from a second position in the original service data, acquiring fragment data comprising a second number as second service data; wherein the sum of the first number and the second number is the total number of fragment data included in the original service data.

For example, the preset combination mode is 2:1, that is, the data of the 4G service and the data of the 5G service in one 5G radio frame are combined according to 2:1, according to the format of the 5G radio frame, the first two chips in every 3 chips in the original data store the data of the 4G service, and one chip is left to store the data of the 5G service, so that the position of the first chip in every 3 chips is the first position, the position of the last chip is the second position, 2 (first number) fragments (chips) are taken from the first position according to the rule until all the data belonging to the 4G service in the original data are taken as the first service data, and the second service data is that 1 (second number) fragment (chip) is taken from all the second positions in the original data as the second service data.

And after the first service data belonging to the 4G service and the second service data belonging to the 5G service are obtained from the original data in a preset combination mode, the second service data are processed in the local board (namely the 5G baseband board), and the steps 102-103 are executed.

Step 102: and converting the first service data into third service data according to the 4G wireless frame data format corresponding to the 4G service.

Step 103: and sending the third service data to the 4G baseband board for processing.

Furthermore, because the 4G service and the 5G service in the 5G base station are combined in a preset combination mode, the occupied resources can be flexibly configured according to actual conditions, the utilization rate of the resources is improved, and the mode is convenient and labor-saving to adjust. The method can meet the requirement of the initial stage of 5G construction, and provides a better 5G construction transition scheme for operators.

Since the 5G baseband board cannot process the data of the 4G service, the first service data needs to be converted into third service data according to the data format of the 4G radio frame, and then the third service data is sent to the 4G baseband board for processing.

The conversion of the first service data into the third service data according to the 4G wireless frame data format corresponding to the 4G service can be realized in the following manner:

encapsulating the first service data according to the 4G wireless frame data format to obtain encapsulated data; checking whether the data format of the packaged data, the time for sending the data to the 4G baseband board are consistent with the receiving time of the 4G baseband board, and if the data format and the receiving time are checked successfully, taking the packaged data as third service data.

Please refer to fig. 3, which is a diagram illustrating a data format of a 4G radio frame. Assuming that the transmission period of the 4G radio frame is 5ms, 200 supergroups, 32 chips are included in one 4G radio frame. Of course each chip may also be sub-divided into smaller granularity, such as including 192 sub-segments (chips), each chip including 32 bits.

It should be understood that one chip in the 4G radio frame contains a different number of chips than one chip in the 5G radio frame, and one chip in the 5G radio frame contains 64 bits.

The first service data is encapsulated according to the data format of the 4G radio frame, and according to the difference of the resource proportion of the data of the 4G service in the 5G radio frame, the data may be encapsulated into 1 4G radio frame, or 2 4G radio frames, or 3 4G radio frames.

And then, checking the packaged data, wherein the checked content comprises whether the data format is correct or not, whether the time for sending the data to the 4G baseband board is consistent with the receiving time of the 4G baseband board or not, and if the check is successful, sending the packaged data to the 4G baseband board as third service data for processing.

By the above-described method, the 5G base station can complete the processing of the uplink data of the 4G service, while the processing of the downlink data of the 4G service mainly combines the data of the 4G service and the data of the 5G service into a 5G radio frame in a preset combination mode, and sends the 5G radio frame to the user terminal through the AAU, and the following processing mode can be adopted:

receiving fourth service data sent by a 4G baseband board; the fourth service data is downlink data of the 4G service; and combining the fourth service data stream and the downlink data sent by the 5G baseband board into fifth service data according to a preset combination mode, and sending the fifth service data to the user terminal.

The fifth service data is downlink data with a 5G radio frame data format, and the downlink data is sent to the user terminal through the AAU.

For example, the fourth service data sent by the 4G baseband board is combined with the downlink data to be sent by the 5G baseband board (i.e. the own board) in a preset combination manner, so as to form fifth service data, and the fifth service data is sent to the user terminal.

and the clock processing unit is used for generating a supergroup number, a supergroup header, a chip number and a chip header in the 4G wireless frame data format according to the reference clock TBU.
