Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. 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 invention.
For the convenience of understanding of the embodiments of the present invention, the following description will be further explained with reference to specific embodiments, which are not to be construed as limiting the embodiments of the present invention.
Fig. 1 is an interaction schematic diagram of a data processing method according to an embodiment of the present invention, as shown in fig. 1, the method specifically includes:
in the data processing method related to this embodiment, data is transmitted between a data sending end and a data receiving end, the data sending end is a BBU, and the data receiving end is an RRU; or, the data sending end is the RRU, and the data receiving end is the BBU. In order to solve the problem of data transmission bandwidth occupancy, in this embodiment, before data transmission is performed between the BBU and the RRU, it is agreed to perform packet compression on data to be transmitted, so as to reduce the bandwidth of an interface occupied by data transmission.
S101, determining compression parameters by the BBU.
The data transmission direction related to this embodiment is that a BBU (data sending end) sends data to an RRU (data receiving end), and an ethernet interface may be used between the BBU and the RRU for data transmission, and specifically, an eCPRI protocol may be used for data transmission, and fig. 2 shows a schematic diagram of a format structure of a message frame specified by the eCPRI protocol related to this embodiment.
The BBU can store various compression parameters in advance, and when data to be transmitted exists, one compression parameter is determined from the various pre-stored compression parameters and serves as the basis of data compression at this time.
Further, the compression parameters can be determined according to the data transmission requirement between the BBU and the RRU to determine the minimum compression (granule) unit of the current compression.
Referring to fig. 3, a schematic diagram of a compression parameter structure according to the present embodiment is shown, as shown in fig. 3, where a horizontal symbol represents a Resource Block (RB) number, a vertical symbol represents a stream number, and each small square identifies a smallest compression granule and corresponds to a compression factor.
S102, the BBU compresses the data to be transmitted according to the compression parameters in a set compression mode to generate a message with a set format.
In this embodiment, because the data to be transmitted is far greater than the maximum packet length of the ethernet, the data may be fragmented, that is, divided into a plurality of ethernet packets for transmission, and the receiving end recovers the entire data after collecting all the packet fragments.
Before data transmission and reception, it is required to contract and transmit data according to a certain time period or data block, the BBU may notify the RRU in a message form, or the base station may notify both the BBU and the RRU.
In an alternative of this embodiment, the set compression method may be, but is not limited to: slot compression, symbol compression, stream compression, RB compression, Resource Element (RE) compression, and the like, in this embodiment, the data to be transmitted may be compressed by using an RB compression method.
Referring to fig. 4 specifically, the BBU performs data compression and transmission according to the sequence of the time slots, compresses the data in time slot 0, sends the compression parameters to the RRU, compresses the data in time slot 1, sends the compression parameters to the RRU, and performs data compression and transmission sequentially.
Specifically, in the time slot 0, the data to be transmitted is compressed into the data block 1 according to the compression parameters and the set compression mode (RB compression), and since the data block 1 is far longer than the maximum packet length of the ethernet, the data block 1 can be split into the 1 st packet and the 2 nd packet, that is, the 1 st packet and the 2 nd packet corresponding to the compressed data block 1 are sent to the RRU in the time slot 0.
When the data block is split, splitting information can be generated, and the splitting information can be: the length of the message, the number of messages, whether the message is the tail of the message, and the like.
Further, the specific compression process may be: and judging the service data in the time slot 0, eliminating invalid data services in the data to be transmitted in the time slot 0 according to the compression parameters, compressing the valid data services, and compressing the valid data services to form a data block 1.
The effective data services include: carrying data fragments such as voice data, image data, video data and the like for data interaction between the BBU and the RRU; the invalid data traffic includes: and data fragments used for data interaction between the BBU and the RRU are not carried, such as data headers or data tails of the data fragments.
Specifically, the data block 1 is split into the 1 st packet and the 2 nd packet, which may be obtained by packing an effective data service according to an eccri packet format to generate a packet in an eccri format, where the effective data service is carried in a payload field of the eccri packet.
S103, determining channel associated information by the BBU.
In this embodiment, in compressing data to be transmitted, it is necessary to record location information of an effective data service (i.e., a location where effective service data exists in the data), where the location information constitutes channel associated information, such as a compression parameter structure shown in fig. 3, where the channel associated information may include a symbol number, a stream number, an RB number (similar to a coordinate of a three-dimensional coordinate system), and a slot number (i.e., it is determined that data corresponding to the channel associated information is data in a several-th slot), and a specific location (a specific slot location and a specific location in the slot) of the effective data service in the compression parameter structure may be determined according to the symbol number, the stream number, the RB number, and the slot number.
S104, the BBU inserts the associated channel information into the message.
In an alternative of this embodiment, the path information may be inserted into a reserved field in a header of the packet, and specifically, one or several bits in the reserved field may be set to store the path information.
For example, referring to fig. 4, the associated information may be inserted into an eccri header of an eccri packet.
It should be noted that the associated information may be inserted into other fields of the packet besides the reserved field in the packet header of the packet, and this may be set according to specific requirements, which is not limited in this embodiment.
In an alternative of this embodiment, timing information may also be inserted into a reserved field in a header of a message, where the timing information may be used to determine that transmission of the BBU and reception of the RRU are synchronized on a clock.
In an alternative of this embodiment, when there is a split condition for a data block, split information also needs to be inserted into a message, such as the length of the message, the number of messages, whether the message is a message tail, and other information. This information may assist the RRU in decompressing the message.
The timing information and the splitting information can be merged into the associated information, or separately exist in a reserved field in a message header of the message.
And S105, the BBU sends the compression parameters and the compression mode to the RRU.
Before or during data transmission, the BBU sends the compression parameters and the compression mode to the RRU, the RRU can determine the minimum compression unit of the message according to the compression parameters, and the message can be decompressed according to the compression mode.
The compression parameter and the compression mode may be sent in a notification message or in other forms, and this embodiment is not limited in particular.
And S106, the BBU sends the message carrying the channel associated information to the RRU.
The BBU may send a packet carrying the associated information to the RRU through a fronthaul interface (ethernet interface).
Further, the packet may also carry timing information, splitting information, and the like.
S107, the RRU extracts the associated information from the message.
And S108, the RRU restores the message into corresponding data according to the channel associated information, the compression parameters and the compression mode.
And the RRU decompresses the message according to the compression parameters and the compression mode, and acquires channel associated information, timing information, splitting information and the like from a reserved field in a message header of the message.
And decompressing the payload field in the message according to the compression parameters and the compression mode, determining the corresponding data block, restoring the position of the effective data service in the message according to the compression parameters and the compression mode, and filling up the vacant invalid data service in a zero form.
When a data block in a certain time slot includes multiple messages, for example, the time slot 0 (time slot number: 0) in fig. 5 includes the 1 st message and the 2 nd message, the 1 st message and the 2 nd message are restored to the data block 1 according to the timing information and the splitting information, that is, the compressed data in the whole time slot 0 is restored.
And restoring the data of the data block 1 into the data to be transmitted of the corresponding BBU in the time slot 0 according to the channel associated information, specifically determining the position of the effective data service in the compression parameter structure body according to the channel associated information, wherein the position can be represented by 1, and the spare part is the invalid data service and can be supplemented by 0.
In the data processing scheme provided by the embodiment of the invention, when data transmission is performed between the BBU and the RRU, a data sending end (BBU or RRU) compresses an effective data service in data to be transmitted according to a compression parameter and a compression mode, and generates channel associated information in the compression process, wherein the channel associated information can reflect position information of the effective data service in the data to be transmitted, and inserts the channel associated information into a compressed message, so that the data service can be recovered in the decompression process. Compared with the existing mode of directly sending without compression, the bandwidth of port service data can be reduced, and the efficiency of data transmission is improved.

The data transmission direction related to this embodiment is that an RRU (data sending end) sends data to a BBU (data receiving end), and an ethernet interface may be used between the BBU and the RRU for data transmission, and specifically, an eccri protocol may be used for data transmission.
The differences between the above S601-S608 and S101-S108 are that only one is used for sending RRU reception for the BBU, and the other is used for sending BBU reception for the RRU, and the execution processes of the two are substantially the same, and for brevity, reference may be specifically made to the above S101-S108, and details are not described here.
