Description
技术领域 technical field
本发明涉及数字信号处理技术领域,尤其是涉及一种多业务混合信号传输方法、装置及系统。The present invention relates to the technical field of digital signal processing, in particular to a multi-service mixed signal transmission method, device and system.
背景技术 Background technique
随着移动通信技术的快速发展,移动通信系统也从第二代移动通信系统(2G,2nd Generation Mobile Communications)过渡到第三代移动通信系统(3G,3rd Generation Mobile Communications),并且逐步向第四代移动通信系统(4G,4th Generation Mobile Communications))演进。在大中城市的室外地区,移动通信信号已经基本可以做到无缝覆盖,但是移动通信信号在室内覆盖存在覆盖盲区。为了增加网络容量,提高网络质量,增加移动通信系统的网络信号在室内的覆盖范围,建设室内覆盖系统成为网络优化的重点。With the rapid development of mobile communication technology, the mobile communication system is also transitioning from the second generation mobile communication system (2G, 2nd Generation Mobile Communications) to the third generation mobile communication system (3G, 3rd Generation Mobile Communications), and gradually to the fourth generation 4th Generation Mobile Communications (4G, 4th Generation Mobile Communications)) evolution. In outdoor areas of large and medium-sized cities, mobile communication signals can basically achieve seamless coverage, but there are coverage blind spots in indoor coverage of mobile communication signals. In order to increase network capacity, improve network quality, and increase the indoor coverage of mobile communication system network signals, building an indoor coverage system has become the focus of network optimization.
在建设室内覆盖系统的方法中,通常采用直放站作为中继,将移动通信系统中的通信信号拉远后传输。如图1所示,采用直放站作为中继的室内覆盖系统,包括至少一个近端设备,和至少一个远端设备。近端设备将接收到的移动通信系统中的通信信号进行模拟信号到数字信号的变换,并将变换后的数字信号通过传输介质拉远传输到远端设备,远端设备将接收到的近端设备传送的数字信号,按照近端设备对接收到的移动通信信号的逆过程处理,将处理后的移动通信信号发送出去,从而达到增大移动通信信号在室内覆盖范围的目的。In the method of constructing an indoor coverage system, a repeater is usually used as a relay to transmit the communication signal in the mobile communication system after a long distance. As shown in FIG. 1 , the indoor coverage system using a repeater as a relay includes at least one near-end device and at least one remote device. The near-end device converts the received communication signal in the mobile communication system from an analog signal to a digital signal, and transmits the transformed digital signal to the remote device through the transmission medium, and the remote device converts the received near-end The digital signal transmitted by the device is processed according to the reverse process of the mobile communication signal received by the near-end device, and the processed mobile communication signal is sent out, so as to achieve the purpose of increasing the indoor coverage of the mobile communication signal.
但是在室内覆盖系统中包括有多种业务混合的数据信号,例如,不同制式的移动通信信号以及宽带以太网数据信号等。上述现有技术中采用直放站作为中继的室内覆盖系统中,仅能够将近端设备接收到的移动通信信号拉远传输到远端设备,然后发送出去,实现移动通信信号在室内的覆盖范围增大,但是无法将室内覆盖系统中除移动通信信号以外的其他业务数据信号进行拉远传输,增加覆盖范围。However, the indoor coverage system includes mixed data signals of various services, for example, mobile communication signals of different standards and broadband Ethernet data signals. In the indoor coverage system using the repeater as the relay in the above prior art, the mobile communication signal received by the near-end device can only be transmitted to the remote device and then sent out to realize the indoor coverage of the mobile communication signal The range is increased, but the indoor coverage system cannot transmit other business data signals other than mobile communication signals to extend the coverage.

针对标准以太网帧中的每个复帧,执行:在该复帧包含的首个子帧中预留前n1位的比特位,并在该复帧的末个子帧中预留后n2位的比特位,在预留的前n1位的比特位中的靠后部分比特位中承载该复帧的前导码信息,并将预留的后n2位的比特位和前n1位的比特位中的剩余比特位作为不同复帧之间的帧间隙;以及在首个子帧和末个子帧中预留比特位之外的载荷承载域,封装变换得到的数字基带信号,并在除首个和末个子帧之外的其他每个子帧中的载荷承载域,分别封装变换得到的数字基带信号和获得的载荷内容信号。For each multiframe in the standard Ethernet frame, perform: reserve the first n1 bits in the first subframe included in the multiframe, and reserve the last n2 bits in the last subframe of the multiframe Bits, the preamble information of the multiframe is carried in the lower bits of the reserved first n1 bits, and the reserved bits of the last n2 bits and the remaining bits of the first n1 bits The bits are used as the frame gap between different multiframes; and the payload carrying domains other than the bits are reserved in the first subframe and the last subframe, and the digital baseband signal obtained by encapsulation and transformation is used, and in the first and last subframes except the first and last subframe The payload bearing field in each subframe other than the ones respectively encapsulates the converted digital baseband signal and the obtained payload content signal.
一种较优的实现方式,如图3所示,为一种可以考虑采用的以太网帧结构示意图,在该以太网帧结构中包括多个复帧,每一个复帧中包括100个连续的子帧。其中,每一个子帧中包括100个比特位,每个子帧的前2个比特位可以但不限于用作传送系统信息的开销比特,除了前2个开销比特之外的其他98个比特位,是以太网帧结构中的载荷承载域,用来传送载荷内容信号。由图3可见每个复帧由连续的100个子帧构成,而每个子帧由100比特位构成,从而就可以构成10K传输的千兆以太网帧,能够充分利用千兆以太网的传输带宽,达到千兆以太网的带宽上限。为了实现将变换得到的数字基带信号和获得的载荷内容信号,封装形成基于以太网帧结构承载的传输信号,针对上述以太网帧结构中的每个复帧,可以执行下述操作:A kind of better realization mode, as shown in Figure 3, is a kind of Ethernet frame structure schematic diagram that can consider adopting, comprise a plurality of multiframes in this Ethernet frame structure, comprise 100 continuous in each multiframe subframe. Wherein, each subframe includes 100 bits, and the first 2 bits of each subframe can be but not limited to be used as overhead bits for transmitting system information, and the other 98 bits except the first 2 overhead bits, It is the load bearing field in the Ethernet frame structure, which is used to transmit the load content signal. It can be seen from Fig. 3 that each multiframe is composed of 100 consecutive subframes, and each subframe is composed of 100 bits, so that a Gigabit Ethernet frame of 10K transmission can be formed, and the transmission bandwidth of Gigabit Ethernet can be fully utilized. Reach the bandwidth limit of Gigabit Ethernet. In order to encapsulate the converted digital baseband signal and the obtained payload content signal into a transmission signal based on the Ethernet frame structure, for each multiframe in the above Ethernet frame structure, the following operations can be performed:
如图4所示,将以太网帧结构中每个复帧中包含的100个子帧按照由0到99的顺序标号,分别记为第0号子帧、第1号子帧……第99号子帧。在第0号子帧中预留前10位的比特位,并在第99号子帧中预留后10位比特位,将第0号子帧中预留的前10位比特位中的前2位比特位和第99号子帧中预留的后10位比特位,一共12个比特位,作为不同复帧之间的帧间隙,即这12个比特位在传输时是空闲比特位;在第0号子帧中预留的前10位比特位的后8位比特位承载该复帧的前导码信息;在第0号子帧中从第11位比特位及其之后开始作为载荷承载域,封装变换得到的数字基带信号,并在第99号子帧中除预留的后10位比特位之外的比特位作为载荷承载域,封装变换得到的数字基带信号;在第1号子帧至第98号子帧的载荷承载域,分别封装变换得到的数字基带信号和获得的载荷内容信号。As shown in Figure 4, the 100 subframes contained in each multiframe in the Ethernet frame structure are numbered in sequence from 0 to 99, and are respectively recorded as the 0th subframe, the 1st subframe ... the 99th subframe. The first 10 bits are reserved in the 0th subframe, and the last 10 bits are reserved in the 99th subframe, and the first 10 bits are reserved in the 0th subframe 2 bits and the last 10 bits reserved in the 99th subframe, a total of 12 bits, used as the frame gap between different multiframes, that is, these 12 bits are idle bits during transmission; The last 8 bits of the first 10 bits reserved in the No. 0 subframe carry the preamble information of the multiframe; in the No. 0 subframe, the bits starting from the 11th bit and thereafter are carried as payloads field, the digital baseband signal obtained by encapsulation and transformation, and the bits other than the reserved last 10 bits in the 99th subframe are used as the payload carrying field to encapsulate the digital baseband signal obtained by transformation; The payload carrying domains from the frame to the 98th subframe respectively encapsulate the converted digital baseband signal and the obtained payload content signal.
上述在对以太网帧结构中每个复帧的处理过程中,做出调整的只有每个复帧中的首个子帧和末个子帧,兼顾了解帧的容易性和传输信号在帧结构中的载荷承载域中的占有率,能够较好地节省系统的处理资源以及多业务混合信号传输系统在实际应用中的可维护性。当进行信号传输时,如果传输带宽成为瓶颈的时侯,可以根据多业务混合信号中各业务信号实际传输所需要的带宽,来确定各业务信号在载荷承载域中所需要的比特位。例如,可以通过调整每个子帧中的比特位,重新定义用作帧间隙的比特位、承载前导码信息的比特位和每个子帧的载荷承载域的比特位等等,来调整各业务信号在载荷承载域中所需要的比特位。In the above process of processing each multiframe in the Ethernet frame structure, only the first subframe and the last subframe in each multiframe are adjusted, taking into account the ease of understanding the frame and the degree of transmission signal in the frame structure Occupancy in the load bearing domain can better save system processing resources and maintainability of the multi-service mixed signal transmission system in practical applications. When performing signal transmission, if the transmission bandwidth becomes a bottleneck, the bits required by each service signal in the payload carrying domain can be determined according to the bandwidth actually required for the transmission of each service signal in the multi-service mixed signal. For example, by adjusting the bits in each subframe, redefining the bits used as interframe gaps, the bits carrying preamble information, and the bits in the payload carrying field of each subframe, etc. Bits required in the payload carrying field.
