Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The frame data processing method applied to the repeater provided in the embodiment of the present application may be applied to a data transmission system of an optical fiber repeater as shown in fig. 1, where the system includes a Base Transceiver Station (BTS), a Multi-service Access Unit (MAU), a plurality of Multi-service extended units (MEU), and a plurality of Multi-service Remote units (MRU). In the system, the input end of the MAU is connected with the output end of the BTS through a coaxial cable 101, and is used for carrying out digital processing on a radio frequency signal transmitted by the output end of the BTS to obtain data which can be transmitted on an optical fiber; the input end of the MEU is connected with the output end of the MAU through an optical fiber 102 and is used for transmitting the radio frequency signal after digital processing; the input end of the MRU is connected to the output end of the MEU via an optical fiber 102, and is configured to process frame data transmitted on the optical fiber to obtain a radio frequency signal that can be transmitted over the air.
The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 2 is a schematic flowchart of a frame data processing method applied to a repeater according to an embodiment, where the method is applied to an application system shown in fig. 1, and the embodiment relates to a process in which an MAU on a transmitting side in the application system digitizes an acquired radio frequency signal. The execution subject of the method is the MAU. As shown in fig. 2, the method comprises the steps of:
s101, combining the radio frequency signals of multiple systems according to a preset frame structure to generate frame data with a first data width.
The radio frequency signals of multiple systems may include radio frequency signals of multiple systems, such as 2G, 3G, 4G, LTE, GSM, CDMA, WCDMA, and the like. The preset frame structure can be customized by a user and is pre-stored on the MAU, so that the MAU can generate frame data according to the defined frame structure, and the frame data can be normally transmitted on the optical fiber. The first data width is a width of a preset frame structure, which may include 16 bits, 64 bits, and the like.
In this embodiment, when the MAU receives radio frequency signals of multiple systems sent by the BTS, the MAU combines the radio frequency signals of the multiple systems according to a preset frame structure to generate frame data having a first data width. The specific process is as follows: the radio frequency signals of each system are filled into an area for storing data signals in a preset frame structure, and meanwhile, the control signals corresponding to the radio frequency signals of each system are filled into an area for storing the control signals in the preset frame structure, so that corresponding frame data can be generated. For example, referring to fig. 2A, fig. 2A is a schematic diagram of a frame structure provided in an embodiment, assuming that the width of the frame structure is 64 bits, an MAU receives radio frequency signals of three systems, 2G, 3G, and 4G, transmitted by a BTS, and a clock frequency is set to T156.25M, the MAU correspondingly fills the radio frequency signals of the three systems to corresponding positions # 11, #12, #13 of a data region in the frame structure shown in fig. 2A, and simultaneously fills control signals corresponding to the radio frequency signals of the three systems to corresponding positions # 01, #02, #03 of a control signal region in the frame structure shown in fig. 2A, and finally generates frame data with a width of 64 bits.
Optionally, in practical applications, the step S101 may be implemented by using a framer or other devices, and this embodiment is not limited to this embodiment.
And S102, encoding the frame data with the first data width to obtain the frame data with the second data width.
The second data width is a width into which frame data having the first data width is converted after being encoded. The second data width may be determined according to an encoding manner. For example, if there is a frame data having a first data width of 8 bits, the frame data is encoded by an 8B/10B encoding method, and the width of the encoded frame data becomes 10 bits. For example, if there is one frame data having a first data width of 64 bits, the frame data is encoded by the 64B/66B encoding method, and the width of the encoded frame data becomes 66 bits.
In this embodiment, the MAU may encode the frame data in a preset encoding manner, so as to implement bit layer processing on the frame data with the first data width before the frame data enters the optical fiber channel for transmission, so as to ensure transmission reliability of the frame data.
Optionally, in practical applications, the step S102 may be implemented by using an encoding module or other encoders, which is not limited to this embodiment.
And S103, performing format conversion processing on the frame data with the second data width to obtain frame data with a third data width.
The third data width refers to a width of coupling data required by an interface of the serializer when the serializer converts the parallel data of the accessed parallel frame data into the serial data.
Therefore, in the present embodiment, when the frame data with the second data width is converted from the parallel data to the serial data by the serializer, the MAU converts the width of the frame data with the second data width into the third data width, so that the frame data with the second data width can be normally coupled to the serializer for the next processing.
Optionally, in practical applications, the step S103 may be implemented by using a format conversion module or other format converters, which is not limited in this embodiment.
And S104, performing data type conversion on the frame data with the third data width by adopting a preset parallel-serial data conversion method to obtain serial frame data for optical fiber transmission.
The data type conversion is to convert parallel frame data into serial frame data so that the frame data can be normally transmitted in the optical fiber.
In practical applications, the serializer is used to convert the parallel-serial data of the frame data, which belongs to a common technology and is not described in detail herein.
In the above embodiment, as in the application system shown in fig. 1, on the transmitting side, when the MAU receives the radio frequency signal, the MAU combines the radio frequency signals of multiple systems according to a preset frame structure to generate frame data with a first data width; meanwhile, the frame data with the first data width is coded to obtain frame data with the second data width; then, carrying out format conversion processing on the frame data with the second data width to obtain frame data with a third data width; and finally, performing data type conversion on the frame data with the third data width by adopting a preset parallel-serial data conversion method to obtain serial frame data for optical fiber transmission. In the process of processing the frame data in the repeater, a preset frame structure is adopted, the frame data with a larger width can be generated, and the frame data is digitized by combining processing methods such as coding, format conversion, parallel-serial data conversion and the like, so that the frame data with the larger width can be obtained, the obtained frame data can bear a larger data volume, and the bandwidth of optical fiber transmission in the repeater is further improved.
Optionally, the frame structure in the above embodiments may include a control word region, a data region, and a blank region. Then, in the above embodiment S101, "combining the radio frequency signals of multiple systems according to a preset frame structure to generate frame data with a first data width" may specifically include: and filling the radio frequency signals of each system into corresponding positions in a data area according to a preset frame structure, and filling the control signals corresponding to the radio frequency signals of each system into the control word area to generate frame data with a first data width.
The control word area is used for storing control signals corresponding to the radio frequency signals of multiple systems received by the MAU; the data area is used for storing the radio frequency signals of multiple systems received by the MAU; the blank area does not store any data and is used for representing invalid data and not transmitting any data, so that the blank area is arranged in the frame structure, the transmission data volume can be increased under the condition of keeping the optical fiber line rate to be constant, and further the transmission bandwidth is increased.
Exemplary description, referring to fig. 3, fig. 3 is a schematic diagram of an improved frame structure according to an embodiment. According to the frame structure shown in fig. 3, assuming that the clock frequency T is 156.25M, if the frame structure is encoded by using a 64B/66B encoding method, the rate of transmission of frame data corresponding to the frame structure in the optical fiber is equal to
156.25M × 64 (20/66) × (66/64) ═ 3.125G; from the calculation formula, when the fiber line rate is 3.125G, the length of the valid data of the improved frame structure in fig. 3 is 20, i.e. the fiber line rate is 3.125G, so that there are a data region with a length of 20 and a blank region with a length of 46 in fig. 3, where the data region further includes a control word region with a width of 16 bits. The frame structure designed in this way can satisfy the condition that the transmission rate of the optical fiber is 3.125G, and therefore, the setting of the effective data length of the frame structure at other fiber line rates is analogized, and the description of the embodiment is not repeated.
Optionally, in practical application, the width of the frame structure is 64 bits, and the frame structure is encoded by using a 64B/66B encoding method. The 64B/66B is a coding and decoding method based on a scrambling mechanism, and the embodiment of the present invention uses the coding method to code the frame structure, so as to increase the data area in the frame structure, and further increase the data amount, thereby further improving the bandwidth of the optical fiber transmission data.
For example, based on the above example, to better explain the technical problem solved by the solution proposed in the present application, that is, the transmission bandwidth of an optical fiber can be increased under the same optical fiber line rate, this embodiment will be described in comparison with a conventional frame structure, referring to fig. 4, fig. 4 is a schematic diagram of a conventional frame structure, and according to the frame structure shown in fig. 4, if the frame structure is encoded by using an 8B/10B encoding method under the condition that the optical fiber line rate is 3.125G and the clock frequency is T156.25M, the data amount (payload) contained in the frame structure is 3.125G 8/10-2500 mbit/s; according to the improved frame structure shown in fig. 3, that is, the design scheme proposed in the present application, assuming that the line rate of the optical fiber is 3.125G, and the clock frequency is T156.25M, if the frame structure is encoded by using a 64B/66B encoding method, the amount of data (payload) contained in the frame structure is 3.125G 64/66 3030 mbit/s; it can be seen that, compared with the conventional frame structure, after the frame structure provided by the present application is subjected to 64B/66B coding, transmission of a larger data amount can be achieved at the same fiber line rate and the same clock frequency, that is, the bandwidth of fiber transmission is greatly increased.
It should be noted that the conventional frame structure cannot be encoded by using a 64B/66B encoding method, and therefore, the improved frame structure proposed by the present application overcomes the limitations of the conventional frame structure and can be encoded by using a 64B/66B encoding method
The 64B/66B coding mode is used for coding, so that the error rate in data transmission is reduced, and the bandwidth of optical fiber transmission data is greatly improved.
Fig. 5 is an implementation manner of S102 in the embodiment of fig. 2. This embodiment relates to a process in which the MAU performs encoding processing on frame data having a first data width. On the basis of the foregoing embodiment, as shown in fig. 5, the foregoing S102 "performing encoding processing on frame data having a first data width to obtain frame data having a second data width" may include the following steps:
s201, performing scrambling processing on the frame data with the first data width to obtain the frame data after scrambling processing.
The scrambling processing is used for reducing the error rate of data transmission caused by environmental factors or other factors. In this embodiment, the process of scrambling the frame data with the first data width by the MAU is as follows: and inputting the frame data with the first data width into a scrambling code polynomial as a variable, and calculating the scrambling code polynomial to obtain an output result, namely the frame data after scrambling processing. The code scrambling polynomial involved can be the following relation (1) or a variant thereof:
y＝1+x39+x58(1)；
wherein, x is frame data required to be input, and y is the frame data after scrambling processing.
S202, adding a data header to the frame data after the scrambling processing, and adjusting the width of the frame data after the scrambling processing to obtain the frame data with the second data width.
The header is used to identify the start and end positions of the data in the frame data in the corresponding time period, and may be represented by two-bit codes, such as binary code 01, 10, 11, and so on.
In this embodiment, after the frame data having the first data width is scrambled and the header is added, the width of the original frame data is changed from the first data width to the second data width. For example, referring to fig. 6, fig. 6 is a schematic diagram of a frame structure according to an embodiment. Fig. 6 shows a frame data having a second data width. As can be seen from this figure, the second data width is 66 bits, which is 64 bits larger than the first data width.
Fig. 7 is a flowchart of a frame data processing method applied in a repeater according to an embodiment, where the method is applied to an application system as shown in fig. 1, and this embodiment relates to a process of processing received frame data by an MRU on a receiving side in the application system, so that the MRU can convert the processed frame data into a corresponding radio frequency signal and send the corresponding radio frequency signal to the air for transmission. The execution subject of the method is the MRU. As shown in fig. 7, the method comprises the steps of:
and S301, performing data type conversion on the serial frame data by adopting a preset serial-parallel data conversion method to obtain frame data with a third data width.
In this case, this step is the reverse of the step S104 in the foregoing embodiment, and mainly converts the serial frame data received by the MRU into parallel frame data for the subsequent processing operation. For details, reference may be made to step S104, and a repeated description is not made herein. It should be noted that, in practical applications, the deserializer may be used to implement the conversion of serial-parallel data of frame data, which belongs to a common technology and is not specifically described herein.
And S302, according to a preset frame structure, performing format reverse conversion processing on the frame data with the third data width to obtain the frame data with the second data width.
In this case, this step is the reverse of the step S103 in the foregoing embodiment, and mainly performs format conversion on the frame data having the third data width so as to restore the data width of the frame data before being input to the serializer, that is, the second data width. For details, reference may be made to step S103, and a repeated description is not made herein.
S303, decoding the frame data with the second data width to obtain the frame data with the first data width.
In this embodiment, this step is the reverse process of step S102 in the foregoing embodiment, and is mainly a process of performing decoding processing on frame data having the second data width, and specific contents may be referred to step S102, and a repeated description is not provided herein. It should be noted that, in practical applications, optionally, the step S303 may be implemented by using a decoding module or other decoders, which is not limited in this embodiment.
Fig. 8 is an implementation manner of S303 in the embodiment of fig. 7. In the embodiment, the process of the MRU performing the decoding process on the frame data with the second data width is described, and on the basis of the above embodiment, as shown in fig. 8, the step S303 "performing the decoding process on the frame data with the second data width to obtain the frame data with the first data width" may include the following steps:
s401, removing a data head in frame data with a second data width;
s402, descrambling the frame data with the second data width and the data head removed to obtain the frame data with the first data width after descrambling.
In this embodiment, this step is the reverse process of the foregoing fig. 5, when the MRU acquires frame data with the second data width, the data header of the frame data may be removed first, and then calculation is performed by using a decoding polynomial, so as to obtain output data subjected to descrambling processing, that is, the frame data with the first data width. It should be noted that the descrambling polynomial here is the same as the scrambling polynomial described in the embodiment of fig. 5, except that the input and output are converted, that is, x in the descrambling polynomial is y in the scrambling polynomial, and y in the descrambling polynomial is x in the scrambling polynomial. And x in the descrambling code polynomial is frame data to be decoded, and y in the descrambling code polynomial is the frame data processed by descrambling.
Before the MRU acquires frame data of the second data width and prepares to remove a data header in the frame data, the following steps may also be implemented: the header in the frame data having the second data width is detected to determine a start position of the frame data having the second data width. In this embodiment, the header of the frame data having the second data width is detected, and the frame data is substantially delimited. The delimitation is to identify the beginning and end of frame data within the respective time period. The detection of the data header may be performed according to the position information of the data header, for example, when the MAU detects that the position rule of the binary code represented by the data header occurs, it may be determined that the data header is the start position of the frame data in the corresponding time period. Referring to the schematic diagram of the frame data structure shown in fig. 9, when the header of the frame data is 10, the header 10 regularly appears once every certain period of time, and the header 10 is determined as the start position of the frame data corresponding to the certain period of time.
It should be understood that although the various steps in the flow charts of fig. 2-9 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows.
