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

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

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

The preset combination manner may be, for example, that the resource occupation 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 resources of 1/3, 2/3, or 3/3 in the 5G radio frame, so that in a 5G radio frame, the combination manner of the data of the 4G service and the data of the 5G service may be as follows: the mode of 1:2 or 2:1 is combined, or the data of 4G service is transmitted completely (for example, when a 5G base station is initially established, no 5G user exists in the coverage area). The determination of the preset combination mode can be determined by counting the number of 4G users and 5G users in the range covered by the 5G base station.

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

Aiming at uplink data (namely original service data) received by the 5G base station, the following processing modes are adopted:

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

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

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

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 according to the preset combination mode, the second service data are processed on the board (i.e. the 5G baseband board), and step 102-step 103 are executed.

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

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

Furthermore, because the 4G service and the 5G service in the 5G base station are combined according to a preset combination mode, the resources occupied by the services can be flexibly configured according to the actual situation, so that the utilization rate of the resources is favorably improved, and the mode is convenient and labor-saving to adjust. The requirement of the initial stage of 5G construction can be met, and a better 5G construction transition scheme is provided 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 4G wireless frame data format, and then the third service data is sent to the 4G baseband board for processing.

Converting the first service data into third service data according to a 4G wireless frame data format corresponding to the 4G service, which can be implemented in the following manner:

packaging the first service data according to a 4G wireless frame data format to obtain packaged data; and checking whether the data format of the packaged data and the time of 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 time of sending the data to the 4G baseband board are both checked successfully, using the packaged data as third service data.

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

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

And encapsulating the first service data according to a 4G wireless frame data format, and according to the difference of the resource proportion of the data of the 4G service in the 5G wireless frame, encapsulating the data into 1 4G wireless frame, or 2 4G wireless frames, or 3 4G wireless frames.

And then, checking the packaged data, wherein the checked content comprises whether the data format is correct and whether the time for sending the data to the 4G baseband board is consistent with the receiving time of the 4G baseband board, and if the data format is correct and the time for sending the data to the 4G baseband board is consistent with the receiving time of the 4G baseband board, sending the packaged data serving as third service data to the 4G baseband board for processing.

Through the above introduced manner, the 5G base station can complete the processing of the 4G service uplink data, and the processing of the 4G service downlink data mainly combines the data of the 4G service and the data of the 5G service into a 5G radio frame according to a preset combination manner, and sends the 5G radio frame to the user terminal through the AAU, and the following processing manners can be adopted:

receiving fourth service data sent by the 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 having a 5G radio frame data format, and the downlink data is transmitted 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 board) according to a preset combination mode, so as to form fifth service data, and the fifth service data is sent to the user terminal.
