本发明涉及直放站技术领域，尤其是涉及一种载波调度方法、装置及系统。The present invention relates to the technical field of repeaters, in particular to a carrier scheduling method, device and system.
背景技术Background technique
随着移动通信技术的快速发展，为了增加移动通信系统的网络信号在室内的覆盖范围，建设室内分布式系统已经成为网络优化的重点。在建设室内分布式系统的方案中，通常采用直放站作为中继，将移动通信系统中的多制式移动通信业务数据以及室内分布式系统中的其他业务数据(如宽带以太网业务数据)一起拉远后传输。With the rapid development of mobile communication technology, in order to increase the indoor coverage of the network signal of the mobile communication system, building an indoor distributed system has become the focus of network optimization. In the scheme of building an indoor distributed system, the repeater is usually used as a relay to combine the multi-standard mobile communication service data in the mobile communication system and other service data (such as broadband Ethernet service data) in the indoor distributed system. Teleport after zooming out.
如图1所示，采用直放站作为中继的室内分布式系统，包括至少一个多业务接入单元(MAU，Multi-service Access Unit)、至少一个多业务扩展单元(MEU，Multi-service Extend Unit)和至少一个多业务远端单元(MRU，Multi-service Remote Unit)。MAU将接收到的从基站发来的多种制式的射频信号，经过变换处理后发送至MEU，MEU将接收到的从MAU发来的经过变换后的多种制式的射频信号以及接收到的室内覆盖系统中其他业务数据信号，经过变换处理后一起发送给MRU，MRU将接收到的多种业务数据的混合信号按照一定规则解析出来并分别发送出去，从而实现多业务混合数据信号在室内的覆盖。As shown in Figure 1, the indoor distributed system using repeaters as relays includes at least one multi-service access unit (MAU, Multi-service Access Unit), at least one multi-service extension unit (MEU, Multi-service Extend Unit) and at least one multi-service remote unit (MRU, Multi-service Remote Unit). The MAU converts the received radio frequency signals of various formats sent from the base station to the MEU after conversion processing, and the MEU receives the converted radio signals of various formats sent from the MAU and the received indoor Cover other business data signals in the system, and send them together to MRU after conversion processing. MRU will analyze the mixed signals of various business data received according to certain rules and send them separately, so as to realize the indoor coverage of multi-service mixed data signals .
采用直放站作为中继的室内分布式系统中，为了便于工程施工以及利用现有的传输资源，在MEU和MRU之间通常采用适合宽带以太网数据传输的传输介质来进行数据传输，例如超五类线(网线)等。由于这种传输介质传输带宽较小，使得整个室内分布式系统的数据传输速率也受到限制。并且，MEU从MAU中获取大容量的数据以后(MAU接收到的由基站下发的射频信号在进行数字化以后，数据量是很大的)，由于受到传输带宽的限制，MEU无法将从MAU接收到的大容量的数据全部传输给MRU，从而导致了通信网络覆盖范围比较小。In the indoor distributed system using the repeater as the relay, in order to facilitate engineering construction and utilize existing transmission resources, the transmission medium suitable for broadband Ethernet data transmission is usually used for data transmission between the MEU and the MRU, such as super Category 5 line (network cable), etc. Due to the small transmission bandwidth of this transmission medium, the data transmission rate of the entire indoor distributed system is also limited. Moreover, after the MEU acquires large-capacity data from the MAU (the radio frequency signal received by the MAU from the base station is digitized, the amount of data is very large), due to the limitation of the transmission bandwidth, the MEU cannot receive the data from the MAU. The received large-capacity data is all transmitted to the MRU, resulting in a relatively small coverage area of the communication network.
现有技术中还没有提出一种方法，解决在采用直放站作为中继的室内分布式系统中，数据传输速率较低、通信网络的覆盖范围比较小，从而影响了话务质量的问题。No method has been proposed in the prior art to solve the problems of low data transmission rate and relatively small coverage of the communication network in an indoor distributed system using a repeater as a relay, thus affecting the traffic quality.

The following will describe this in detail in combination with different embodiments. The technical scheme and realization principle of the invention.
实施例一Embodiment one
如图2所示，为本发明实施例一这里提出的载波调度系统的结构组成图。其中本发明实施例的载波调度方法就可以基于该系统架构来实现，该系统架构包括至少一个MAU、至少一个MEU和至少一个MRU，还包括一个载波调度装置。需要说明的是，本发明实施例一这里提出的载波调度系统，可以具备上行链路和/或下行链路的处理能力，本发明实施例一这里以其同时具备上下行链路的处理能力为例来进行说明，但是本发明实施例一这里保护的载波调度系统也可以只有下行链路处理能力或者上行链路处理能力。As shown in FIG. 2 , it is a structural diagram of the carrier scheduling system proposed here in Embodiment 1 of the present invention. The carrier scheduling method in the embodiment of the present invention can be implemented based on the system architecture, and the system architecture includes at least one MAU, at least one MEU, and at least one MRU, and also includes a carrier scheduling device. It should be noted that the carrier scheduling system proposed here in Embodiment 1 of the present invention may have uplink and/or downlink processing capabilities. An example is used for description, but the carrier scheduling system protected here in the embodiment of the present invention may also only have the downlink processing capability or the uplink processing capability.
基于该系统架构，在下行链路中：Based on this system architecture, in the downlink:
MAU，用于接收基站发送的至少一路相同制式或不同制式的射频信号，以及将接收到的至少一路相同制式或不同制式的射频信号变换成数字基带信号后通过MAU和MEU之间的传输介质传输至MEU，以及将变换成的数字基带信号通过MAU和载波调度装置之间的传输介质传输至载波调度装置中。MAU is used to receive at least one radio frequency signal of the same standard or a different standard sent by the base station, and convert at least one radio frequency signal received of the same standard or a different standard into a digital baseband signal and transmit it through the transmission medium between the MAU and the MEU to the MEU, and transmit the converted digital baseband signal to the carrier scheduling device through the transmission medium between the MAU and the carrier scheduling device.
其中，MAU与基站之间的传输介质可以但不限于是同轴电缆，用于传输从基站接收的射频信号，并将接收到的下行信号进行数字化处理。例如，MAU可以从基站耦合2G、3G和LTE等一同通信制式的射频信号。Wherein, the transmission medium between the MAU and the base station may be but not limited to a coaxial cable, which is used to transmit the radio frequency signal received from the base station, and perform digital processing on the received downlink signal. For example, the MAU can couple radio frequency signals of 2G, 3G, LTE and other common communication standards from the base station.
载波调度装置，用于获得MAU发来的数字基带信号和以太网设备发来的以太网数据业务信号，在获得的数字基带信号中确定载波信号，将确定出的载波信号进行调度，确定出与对应的MRU匹配的载波信号，并且，将获得的以太网数据业务信号进行调度，确定出与对应的MRU匹配的以太网数据业务信号，然后将确定出的载波信号和以太网数据业务信号进行合并处理，形成基于以太网帧结构承载的传输信号，最后将形成的传输信号传输至对应的MRU。The carrier scheduling device is used to obtain the digital baseband signal sent by the MAU and the Ethernet data service signal sent by the Ethernet device, determine the carrier signal in the obtained digital baseband signal, schedule the determined carrier signal, and determine the The carrier signal matched by the corresponding MRU, and the obtained Ethernet data service signal is scheduled, and the Ethernet data service signal matching the corresponding MRU is determined, and then the determined carrier signal and the Ethernet data service signal are combined processing to form a transmission signal based on the Ethernet frame structure, and finally transmit the formed transmission signal to a corresponding MRU.
其中，载波调度装置可以在MEU中获得数字基带信号，，载波调度装置也可以直接在MAU中获得数字基带信号。由于获得的数字基带信号的帧结构中，定义了部分开销字节用来承载MAU以及MEU的高级数据链路控制(HDLC，High-Level Data Link Control)信息，载波调度的控制可以基于此完成。Wherein, the carrier scheduling device can obtain the digital baseband signal in the MEU, and the carrier scheduling device can also directly obtain the digital baseband signal in the MAU. Because in the frame structure of the obtained digital baseband signal, some overhead bytes are defined to carry the high-level data link control (HDLC, High-Level Data Link Control) information of MAU and MEU, and the control of carrier scheduling can be completed based on this.
其中，由于不同的MRU设置在不同的区域，且不同区域的用户对通信网络的覆盖范围以及使用量的需求也大不相同，所以载波调度装置在对获得的载波进行调度时，可以但不限于采用下述两种方式：Wherein, since different MRUs are set in different areas, and users in different areas have very different requirements on the coverage and usage of the communication network, the carrier scheduling device may, but is not limited to, when scheduling the obtained carriers, Use the following two methods:
第一种方式：载波调度装置可以根据不同的MRU对载波信号的不同需求，将获得的载波信号进行调度，确定出与该MRU匹配的载波信号。例如，假设有4个MRU，分别设置在区域1～区域4，对于区域1来说，由于用户对通信网络的需要，有明显的时间性，假设区域1属于商业区，则白天的时候用户比较多，对通信网络的需求也比较大，夜晚的时候用户比较少，对通信网络的需求比较小，所以，载波调度装置可以为设置在区域1的MRU，按照时间对获得的载波进行调度，在白天的时候为该区域1的MRU多分配一些载波，保证通信网络的畅通，在夜晚的时候，可以对获得的载波进行重新调度，为该区域1的MRU少分配一些载波。基于同样的载波调度实现方案，对设置在其他区域的MRU，也根据用户对通信网络的实际需求进行载波调度。The first way: the carrier scheduling device can schedule the obtained carrier signals according to the different requirements of different MRUs for the carrier signals, and determine the carrier signals matching the MRU. For example, assume that there are 4 MRUs, which are respectively installed in areas 1 to 4. For area 1, due to the needs of users for the communication network, there is obvious timeliness. Assuming that area 1 belongs to the commercial area, users compare There are many, and the demand for the communication network is relatively large. There are fewer users at night, and the demand for the communication network is relatively small. Therefore, the carrier scheduling device can be the MRU set in area 1, and schedule the obtained carriers according to time. During the day, more carriers are allocated to the MRUs in this area 1 to ensure the smooth flow of the communication network. At night, the acquired carriers can be rescheduled to allocate fewer carriers to the MRUs in this area 1. Based on the same carrier scheduling implementation scheme, the MRUs installed in other areas also perform carrier scheduling according to the actual needs of users for the communication network.
第二种方式，载波调度装置还可以对与MEU相连的MRU的总数量进行统计，然后根据统计出的MRU的数量，将获得的载波信号进行平均分配处理，确定出于每个MRU匹配的载波信号。In the second way, the carrier scheduling device can also count the total number of MRUs connected to the MEU, and then according to the counted number of MRUs, averagely distribute the obtained carrier signals to determine the matching carrier for each MRU Signal.
具体地，载波调度装置对获得的载波进行调度时，可以重复调度。其中，对获得的载波信号进行重复调度的条件可以但不限于为以下两种：Specifically, when the carrier scheduling device schedules the obtained carriers, the scheduling may be repeated. Wherein, the conditions for repeatedly scheduling the obtained carrier signal may be, but not limited to, the following two types:

实施例二Embodiment two
进一步地，本发明实施例二基于上述实施例以中介绍的载波调度系统的结构组成，来详细阐述载波调度方法流程。如图3所示，具体过程如下：Further, Embodiment 2 of the present invention elaborates the flow of the carrier scheduling method in detail based on the structural composition of the carrier scheduling system introduced in the foregoing embodiments. As shown in Figure 3, the specific process is as follows:
基于上述实施例一的系统架构，在下行链路中：Based on the system architecture of the first embodiment above, in the downlink:
步骤301，载波调度装置获得MAU发来的数字基带信号。
其中，MAU接收基站发来的至少一路相同制式或者不同制式的射频信号，并且将接收到的射频信号经过数字化处理，形成数字基带信号，通过传输介质传输至MEU。载波调度装置可以从MAU中获得形成的数字基带信号，也可以在MEU中获得MAU发来的数字基带信号。The MAU receives at least one radio frequency signal of the same standard or a different standard from the base station, and digitally processes the received radio frequency signal to form a digital baseband signal, which is transmitted to the MEU through a transmission medium. The carrier scheduling device can obtain the formed digital baseband signal from the MAU, and can also obtain the digital baseband signal from the MAU in the MEU.
步骤302，在步骤301中获得的数字基带信号中确定载波信号。In
其中，如果获得的数字基带信号中包含有多种不同制式的射频信号，则在获得的数字基带信号中，分别确定出与归属于不同制式的射频信号的载波信号。Wherein, if the obtained digital baseband signal contains multiple radio frequency signals of different standards, the carrier signals belonging to the radio frequency signals of different standards are respectively determined in the obtained digital baseband signal.
步骤303，将步骤302中确定出的载波信号进行调度，确定出与对应的MRU匹配的载波信号。In
其中，由于不同的MRU设置在不同的区域，且不同区域的用户对通信网络的覆盖范围以及通信网络的使用量的需求也大不相同，所以载波调度装置在对获得的载波进行调度时，可以但不限于采用下述两种方式：Wherein, since different MRUs are set in different areas, and users in different areas have very different demands on the coverage of the communication network and the usage of the communication network, when the carrier scheduling device schedules the obtained carriers, it can But not limited to the following two methods:
第一种方式：载波调度装置可以根据不同的MRU对载波信号的不同需求，将获得的载波信号进行调度，确定出与该MRU匹配的载波信号。例如，假设有4个MRU，分别设置在区域1～区域4，对于区域1来说，由于用户对通信网络的需要，有明显的时间性，白天的时候用户比较多，对通信网络的需求也比较大，夜晚的时候用户比较少，对通信网络的需求比较小，所以，载波调度装置可以为设置在区域1的MRU，按照时间对获得的载波进行调度，在白天的时候为该区域1的MRU多分配一些载波，保证通信网络的畅通，在夜晚的时候，可以对获得的载波进行重新调度，为该区域1的MRU少分配一些载波。基于同样的载波调度实现方案，对设置在其他区域的MRU，也根据用户对通信网络的实际需求进行载波调度。The first way: the carrier scheduling device can schedule the obtained carrier signals according to the different requirements of different MRUs for the carrier signals, and determine the carrier signals matching the MRU. For example, assuming that there are 4 MRUs, which are respectively installed in areas 1 to 4, for area 1, due to the obvious timeliness of users’ needs for the communication network, there are more users during the day, and the needs for the communication network are also relatively large, there are fewer users at night, and the demand for the communication network is relatively small. Therefore, the carrier scheduling device can be an MRU installed in area 1, which schedules the obtained carriers according to time. The MRU allocates more carriers to ensure the smooth flow of the communication network. At night, the obtained carriers can be rescheduled to allocate less carriers to the MRU in area 1. Based on the same carrier scheduling implementation scheme, the MRUs installed in other areas also perform carrier scheduling according to the actual needs of users for the communication network.
第二种方式，载波调度装置还可以对与MEU相连的MRU的总数量进行统计，然后根据统计出的MRU的数量，将获得的载波信号进行平均分配处理，确定出于每个MRU匹配的载波信号。In the second way, the carrier scheduling device can also count the total number of MRUs connected to the MEU, and then according to the counted number of MRUs, averagely distribute the obtained carrier signals to determine the matching carrier for each MRU Signal.
具体地，载波调度装置对获得的载波信号进行调度时，可以将获得的载波信号重复调度。其中，对获得的载波信号进行重复调度的条件可以但不限于为以下两种：Specifically, when the carrier scheduling device schedules the obtained carrier signals, it may repeatedly schedule the obtained carrier signals. Wherein, the conditions for repeatedly scheduling the obtained carrier signal may be, but not limited to, the following two types:
第一种方式：在确定出获得的载波信号全部调度完毕，且存在至少一个MRU未进行载波信号匹配时，对已经进行调度的载波信号再次进行调度。The first manner: when it is determined that all the obtained carrier signals have been scheduled and there is at least one MRU that has not performed carrier signal matching, re-schedule the scheduled carrier signals.
第二种方式：在确定出未进行调度的载波信号不能够与MRU匹配时，对已经进行调度的载波信号再次进行调度。The second way: when it is determined that the carrier signals that have not been scheduled cannot match the MRU, re-schedule the carrier signals that have been scheduled.
步骤304，获得以太网设备发来的以太网数据业务信号。
其中，载波调度装置可以直接从MEU中获得以太网设备发来的以太网数据业务信号。一种较佳的实现方式，本发明实施例这里，载波调度装置在MEU中分别获得MAU发来的数字基带信号和以太网设备发来的以太网数据业务信号。然后再对获得的数字基带信号和以太网数据业务信号分别进行后续处理，这样可以较好地节省系统的处理资源。Wherein, the carrier scheduling device can directly obtain the Ethernet data service signal sent by the Ethernet device from the MEU. In a preferred implementation manner, in this embodiment of the present invention, the carrier scheduling device separately obtains the digital baseband signal sent by the MAU and the Ethernet data service signal sent by the Ethernet device in the MEU. Then, subsequent processing is performed on the obtained digital baseband signal and the Ethernet data service signal respectively, which can better save system processing resources.
步骤305，将获得的以太网数据业务信号进行调度，确定出与对应的MRU匹配的以太网数据业务信号。Step 305: Scheduling the obtained Ethernet data service signals to determine the Ethernet data service signals matching the corresponding MRU.
其中，对获得的以太网数据业务信号进行调度时，也可以将获得的以太网数据业务信号重复调度。Wherein, when scheduling the obtained Ethernet data service signal, the obtained Ethernet data service signal may also be repeatedly scheduled.
步骤306，将调度后的载波信号和以太网数据业务信号进行合并处理，形成基于以太网帧结构承载的传输信号，然后将形成的传输信号传输至对应的MRU。Step 306: Combine the scheduled carrier signal and the Ethernet data service signal to form a transmission signal based on the Ethernet frame structure, and then transmit the formed transmission signal to the corresponding MRU.
在上行链路中：In the uplink:
步骤307，接收至少一个MRU发来的基于以太网帧结构承载的传输信号。
在实际应用中，为了增加通信网络的覆盖范围，会在不同的区域设置MRU，每个MRU通过传输介质与MEU连接，在现有的采用直放站作为中继的室内分布式系统中(其结构组成如图1)，在每个MEU下至多可以连接8个MRU，相对于MEU来说，每个MRU相当于一个网口。当然，对于室内分布式系统中的每个MEU来说，也可以不与任何一个MRU连接，也可以只连接N个MRU，其中，N＜8。In practical applications, in order to increase the coverage of the communication network, MRUs will be set up in different areas, and each MRU is connected to the MEU through a transmission medium. In the existing indoor distributed system using repeaters as relays (other The structural composition is shown in Figure 1). Each MEU can connect up to 8 MRUs. Compared with the MEU, each MRU is equivalent to a network port. Of course, each MEU in the indoor distributed system may not be connected to any MRU, or may only be connected to N MRUs, where N<8.
其中，载波调度装置可以在MEU中获得MRU发来的基于以太网帧结构承载的传输信号，也可以将载波调度装置与每个MRU连接，获得MRU发来的基于以太网帧结构承载的传输信号。较佳地，本发明实施例这里，载波调度装置在MEU中获得MRU发来的基于以太网帧结构承载的传输信号，这样，可以较好的节省系统的布线资源，降低工程施工成本。Among them, the carrier scheduling device can obtain the transmission signal based on the Ethernet frame structure from the MRU in the MEU, or connect the carrier scheduling device to each MRU to obtain the transmission signal based on the Ethernet frame structure from the MRU. . Preferably, in this embodiment of the present invention, the carrier scheduling device obtains the transmission signal based on the Ethernet frame structure from the MRU in the MEU. In this way, the wiring resources of the system can be better saved and the construction cost can be reduced.
步骤308，在接收到的传输信号中，对其数据帧结构进行解析处理，获得其中承载的数字基带信号和以太网数据业务信号。Step 308: Analyze and process the data frame structure of the received transmission signal to obtain the digital baseband signal and Ethernet data service signal carried therein.
步骤309，在获得的数字基带信号中确定出载波信号，然后将确定出的载波信号和以太网数据业务信号传输至MEU。In
其中，由于在进行载波调度时，对于同一个载波信号来说，可以对其进行重复调度，然后分配给MRU，所以在获得的数字基带信号中，也存在重复分配的载波信号，此时，需要在确定出的载波信号中有重复分配的载波信号时，对重复的载波信号进行合路处理。Wherein, because when carrier scheduling is carried out, for the same carrier signal, it can be repeatedly scheduled and then allocated to the MRU, so in the obtained digital baseband signal, there are also carrier signals that are repeatedly allocated. At this time, it is necessary to When there is a carrier signal that is allocated repeatedly among the determined carrier signals, combine processing is performed on the repeated carrier signals.
同理，如果在获得的以太网数据业务信号中有重复分配的以太网数据业务信号时，也需要对重复的以太网数据业务信号进行合路处理。Similarly, if there are redundantly distributed Ethernet data service signals among the obtained Ethernet data service signals, it is also necessary to combine the repeated Ethernet data service signals.
本发明实施例二这里提出的载波调度的方法，适合应用在楼宇密集型等热点地区，既能够满足通信网络大范围的覆盖、也能够在使得大容量的数据在采用直放站作为中继的室内分布式系统中的传输，同时支持灵活的组网方式，实现室内精确的覆盖，并且便于工程施工，节省工程建设的成本。能够较好地提高其覆盖区域的话务质量，提升用户的感知度。The carrier scheduling method proposed here in the second embodiment of the present invention is suitable for application in hotspot areas such as dense buildings, which can not only meet the large-scale coverage of the communication network, but also enable large-capacity data to use repeaters as relays. The transmission in the indoor distributed system also supports flexible networking methods to achieve accurate indoor coverage, facilitates engineering construction, and saves engineering construction costs. It can better improve the traffic quality in its coverage area and enhance the user's perception.

实施例四Embodiment four
本发明实施例四这里提出载波调度系统，其结构组成如图1所示，将载波调度装置集成在MEU中(图1未示出)，该系统架构包括至少一个一个MAU、至少一个MEU和至少一个MRU，基于该系统架构，在下行链路中：Embodiment 4 of the present invention proposes a carrier scheduling system here, its structural composition is shown in Figure 1, the carrier scheduling device is integrated in the MEU (not shown in Figure 1), the system architecture includes at least one MAU, at least one MEU and at least An MRU, based on the system architecture, in the downlink:
MAU，用于接收基站发送的至少一路相同制式或不同制式的射频信号，以及将接收到的至少一路相同制式或不同制式的射频信号变换成数字基带信号后通过MAU和MEU之间的传输介质传输至MEU，以及将变换成的数字基带信号通过MAU和载波调度装置之间的传输介质传输至载波调度装置中。MAU is used to receive at least one radio frequency signal of the same standard or a different standard sent by the base station, and convert at least one radio frequency signal received of the same standard or a different standard into a digital baseband signal and transmit it through the transmission medium between the MAU and the MEU to the MEU, and transmit the converted digital baseband signal to the carrier scheduling device through the transmission medium between the MAU and the carrier scheduling device.
其中，MAU与基站之间的传输介质可以但不限于是同轴电缆，用于传输从基站接收的射频信号，并将接收到的下行信号进行数字化处理。例如，MAU可以从基站耦合2G、3G和LTE等移动通信制式的射频信号。Wherein, the transmission medium between the MAU and the base station may be but not limited to a coaxial cable, which is used to transmit the radio frequency signal received from the base station, and perform digital processing on the received downlink signal. For example, the MAU can couple radio frequency signals of mobile communication standards such as 2G, 3G and LTE from the base station.
MEU，如图5所示的MEU内部原理示意图，载波调度装置作为一个模块集成在MEU中。MEU用于接收MAU发来的数字基带信号和以太网设备发来的以太网数据业务信号，在获得的数字基带信号中确定载波信号，将确定出的载波信号进行调度，确定出与MEU连接的相应的MRU匹配的载波信号，并且，将获得的以太网数据业务信号进行调度，确定出与对应的MRU匹配的以太网数据业务信号，然后将确定出的载波信号和以太网数据业务信号进行合并处理，形成基于以太网帧结构承载的传输信号，最后将形成的传输信号传输至对应的MRU。The MEU is a schematic diagram of the internal principle of the MEU as shown in FIG. 5 , and the carrier scheduling device is integrated in the MEU as a module. The MEU is used to receive the digital baseband signal sent by the MAU and the Ethernet data service signal sent by the Ethernet device, determine the carrier signal in the obtained digital baseband signal, schedule the determined carrier signal, and determine the The carrier signal matched by the corresponding MRU, and the obtained Ethernet data service signal is scheduled, and the Ethernet data service signal matching the corresponding MRU is determined, and then the determined carrier signal and the Ethernet data service signal are combined processing to form a transmission signal based on the Ethernet frame structure, and finally transmit the formed transmission signal to a corresponding MRU.
其中，在接收到的MAU发来的数字基带信号的帧结构中，定义了部分开销字节用来承载MAU以及MEU的HDLC信息(如图5中的监控)，载波调度的控制可以基于此完成。Among them, in the frame structure of the digital baseband signal received from the MAU, some overhead bytes are defined to carry the HDLC information of the MAU and MEU (as shown in the monitoring in Figure 5), and the control of carrier scheduling can be completed based on this .
其中，由于不同的MRU设置在不同的区域，且不同区域的用户对通信网络的覆盖范围以及使用量的需求也大不相同，所以MEU在对获得的载波进行调度时，可以但不限于采用下述两种方式：Among them, since different MRUs are set in different areas, and users in different areas have very different requirements on the coverage and usage of the communication network, so when the MEU schedules the obtained carriers, it can, but is not limited to, adopt the following Described in two ways:
第一种方式：可以根据不同的MRU对载波信号的不同需求，将获得的载波信号进行调度，确定出与该MRU匹配的载波信号。例如，假设有4个MRU，分别设置在区域1～区域4，对于区域1来说，用户对通信网络的需要，有明显的时间性，区域1属于住宅区，夜晚的时候用户比较多，对通信网络的需求也比较大，白天的时候用户比较少，对通信网络的需求比较小，所以，可以为设置在区域1的MRU，按照时间对获得的载波进行调度，在夜晚的时候为该区域1的MRU多分配一些载波，保证通信网络的畅通，在白天的时候，可以对获得的载波进行重新调度，为该区域1的MRU少分配一些载波。基于同样的载波调度实现方案，对设置在其他区域的MRU，也根据用户对通信网络的实际需求进行载波调度。The first way: according to the different requirements of different MRUs for carrier signals, the obtained carrier signals can be scheduled to determine the carrier signal matching the MRU. For example, assume that there are 4 MRUs, which are respectively installed in areas 1 to 4. For area 1, the needs of users for the communication network have obvious timeliness. Area 1 is a residential area, and there are more users at night. The demand for the communication network is also relatively large. During the day, there are fewer users, and the demand for the communication network is relatively small. Therefore, the MRU set in area 1 can schedule the obtained carriers according to time, and at night for this area. The MRU of 1 allocates more carriers to ensure the smooth flow of the communication network. During the daytime, the obtained carriers can be rescheduled to allocate less carriers to the MRU of area 1. Based on the same carrier scheduling implementation scheme, the MRUs installed in other areas also perform carrier scheduling according to the actual needs of users for the communication network.
第二种方式，还可以对与MEU相连的MRU的总数量进行统计，然后根据统计出的MRU的数量，将获得的载波信号进行平均分配处理，确定出于每个MRU匹配的载波信号。In the second way, the total number of MRUs connected to the MEU can also be counted, and then according to the counted number of MRUs, the obtained carrier signals can be evenly distributed to determine the carrier signal matched by each MRU.
具体地，对获得的载波进行调度时，可以重复调度。其中，对获得的载波信号进行重复调度的条件可以但不限于为以下两种方式：Specifically, when scheduling the obtained carriers, the scheduling may be repeated. Wherein, the conditions for repeatedly scheduling the obtained carrier signal may be, but not limited to, the following two ways:

实施例五Embodiment five
基于实施例四，相应地，本发明实施例五这里基于上述实施例四中介绍的载波调度系统，提出一种载波调度方法，其处理流程如下：Based on Embodiment 4, correspondingly, Embodiment 5 of the present invention proposes a carrier scheduling method based on the carrier scheduling system introduced in Embodiment 4 above, and its processing flow is as follows:
步骤一，MEU获得MAU发来的数字基带信号。In step 1, the MEU obtains the digital baseband signal sent by the MAU.
其中，MAU接收基站发来的至少一路相同制式或者不同制式的射频信号，并且将接收到的射频信号经过数字化处理，形成数字基带信号，通过传输介质传输至MEU。The MAU receives at least one radio frequency signal of the same standard or a different standard from the base station, and digitally processes the received radio frequency signal to form a digital baseband signal, which is transmitted to the MEU through a transmission medium.
步骤二，在获得的数字基带信号中确定载波信号。其中，如果获得的数字基带信号中包含有多种不同制式的射频信号，则在获得的数字基带信号中，分别确定出与归属于不同制式的射频信号的载波信号。Step 2, determining the carrier signal in the obtained digital baseband signal. Wherein, if the obtained digital baseband signal contains multiple radio frequency signals of different standards, the carrier signals belonging to the radio frequency signals of different standards are respectively determined in the obtained digital baseband signal.
步骤三，将确定出的载波信号进行调度，确定出与对应的MRU匹配的载波信号。Step 3: Scheduling the determined carrier signal to determine the carrier signal matching the corresponding MRU.
具体地，步骤三中的具体实施方法请参阅上述实施例二中步骤303中的详细阐述，这里不再赘述。Specifically, for the specific implementation method in step three, please refer to the detailed description in
步骤四，获得以太网设备发来的以太网数据业务信号。Step 4, obtaining the Ethernet data service signal sent by the Ethernet device.
步骤五，将获得的以太网数据业务信号进行调度，确定出与对应的MRU匹配的以太网数据业务信号。Step 5: Scheduling the obtained Ethernet data service signal, and determining the Ethernet data service signal matching the corresponding MRU.
其中，对获得的以太网数据业务信号进行调度时，也可以将获得的以太网数据业务信号重复调度。Wherein, when scheduling the obtained Ethernet data service signal, the obtained Ethernet data service signal may also be repeatedly scheduled.
步骤六，将调度后的载波信号和以太网数据业务信号进行合并处理，形成基于以太网帧结构承载的传输信号，然后将形成的传输信号传输至对应的MRU。Step 6: Combine the scheduled carrier signal and the Ethernet data service signal to form a transmission signal based on the Ethernet frame structure, and then transmit the formed transmission signal to the corresponding MRU.
在上行链路中：In the uplink:
步骤七，MEU接收至少一个MRU发来的基于以太网帧结构承载的传输信号。In step seven, the MEU receives the transmission signal based on the Ethernet frame structure from at least one MRU.
在实际应用中，为了增加通信网络的覆盖范围，会在不同的区域设置MRU，每个MRU通过传输介质与MEU连接，在现有的采用直放站作为中继的室内分布式系统中(其结构组成如图1)，在每个MEU下至多可以连接8个MRU，相对于MEU来说，每个MRU相当于一个网口。当然，对于室内分布式系统中的每个MEU来说，也可以不与任何一个MRU连接，也可以只连接N个MRU，其中，N＜8。In practical applications, in order to increase the coverage of the communication network, MRUs will be set up in different areas, and each MRU is connected to the MEU through a transmission medium. In the existing indoor distributed system using repeaters as relays (other The structural composition is shown in Figure 1). Each MEU can connect up to 8 MRUs. Compared with the MEU, each MRU is equivalent to a network port. Of course, each MEU in the indoor distributed system may not be connected to any MRU, or may only be connected to N MRUs, where N<8.
步骤八，在接收到的传输信号中，对其数据帧结构进行解析处理，获得其中承载的数字基带信号和以太网数据业务信号。Step 8: Analyze and process the data frame structure of the received transmission signal to obtain the digital baseband signal and Ethernet data service signal carried therein.
步骤九，在获得的数字基带信号中确定出载波信号，然后将确定出的载波信号传输至MAU，同时，将确定出的以太网数据业务信号传输至以太网设备。Step 9: Determine the carrier signal from the obtained digital baseband signal, and then transmit the determined carrier signal to the MAU, and at the same time, transmit the determined Ethernet data service signal to the Ethernet device.
其中，由于在进行载波调度时，对于同一个载波信号来说，可以对其进行重复调度，然后分配给MRU，所以在获得的数字基带信号中，也存在重复分配的载波信号，此时，需要在确定出的载波信号中有重复分配的载波信号时，对重复的载波信号进行合路处理。Wherein, because when carrier scheduling is carried out, for the same carrier signal, it can be repeatedly scheduled and then allocated to the MRU, so in the obtained digital baseband signal, there are also carrier signals that are repeatedly allocated. At this time, it is necessary to When there is a carrier signal that is allocated repeatedly among the determined carrier signals, combine processing is performed on the repeated carrier signals.
同理，如果在获得的以太网数据业务信号中有重复分配的以太网数据业务信号时，也需要对重复的以太网数据业务信号进行合路处理。Similarly, if there are redundantly distributed Ethernet data service signals among the obtained Ethernet data service signals, it is also necessary to combine the repeated Ethernet data service signals.
本发明实施例五这里提出的载波调度的方法，适合应用在楼宇密集型等热点地区，既能够满足通信网络大范围的覆盖、也能够在使得大容量的数据在采用直放站作为中继的室内分布式系统中的传输，同时支持灵活的组网方式，实现室内精确的覆盖，并且便于工程施工，节省工程建设的成本。能够较好地提高其覆盖区域的话务质量，提升用户的感知度。The carrier scheduling method proposed here in Embodiment 5 of the present invention is suitable for application in hotspot areas such as dense buildings, which can not only meet the wide-range coverage of the communication network, but also enable large-capacity data to use repeaters as relays. The transmission in the indoor distributed system also supports flexible networking methods to achieve accurate indoor coverage, facilitates engineering construction, and saves engineering construction costs. It can better improve the traffic quality in its coverage area and enhance the user's perception.

实施例七Embodiment seven
基于上述实施例一～实施例六中的详细阐述，进一步地，本发明实施例七这里以将载波调度装置设置在MEU中为例，MAU端接收到24载波GSM信号和45M宽带WCDMA信号为例，来详细阐述本发明这里提出的技术方案。如图7所示，其具体处理流程如下：Based on the detailed elaboration in Embodiment 1 to Embodiment 6 above, further, Embodiment 7 of the present invention here takes setting the carrier scheduling device in the MEU as an example, and the MAU end receives 24 carrier GSM signals and 45M wideband WCDMA signals as an example. , to elaborate the technical solution proposed here in the present invention. As shown in Figure 7, the specific processing flow is as follows:
在下行链路中：In the downlink:
步骤701，MAU接收基站发来的GSM射频信号，将接收到的射频信号经过数字化处理，形成数字基带信号，通过传输介质传输至MEU。In
步骤702，MEU在获得的数字基带信号中确定24载波的GSM信号。In
其中，在获得的数字基带信号的传输帧结构中，包含有开销字节和保留字节。整个帧传输频率为125M，帧宽为24bit，所以传输速率为3G。每个GSM载波信号在所述帧结构中都有其唯一的位置，在相应的位置将载波信号从数字基带信号的传输帧中解析出来。Wherein, the obtained transmission frame structure of the digital baseband signal includes overhead bytes and reserved bytes. The entire frame transmission frequency is 125M, and the frame width is 24bit, so the transmission rate is 3G. Each GSM carrier signal has its unique position in the frame structure, and the carrier signal is resolved from the transmission frame of the digital baseband signal at the corresponding position.
步骤703，MEU获得以太网设备发来的以太网业务数据信号。In
其中，在以太网业务数据信号的帧结构中，以太网业务数据信号也有其唯一的位置。在相应的位置在以太网业务数据信号帧中将以太网数据信号解析出来。Wherein, in the frame structure of the Ethernet service data signal, the Ethernet service data signal also has its unique position. The Ethernet data signal is parsed out in the Ethernet service data signal frame at a corresponding position.
步骤704，将确定出的载波信号和获得的以太网业务数据信号进行调度，确定出于对应的MRU匹配的载波信号。
如图8所示，将WCDMA分3个15M选频来实现对以太网业务数据信号的调度。假设3个15M宽带选频信号编号依次为1～3。24载波GSM信号编号依次为0～23。如图8所示包含8个载波GSM信号和一个15M宽带选频信号。所以每一个MRU最多能获得8载波GSM载波信号和一个15M宽带选频信号。例如，图8中网口0(与MEU连接的编号为0号的MRU)分配到了3～10号的载波信号和2号宽带选频数据，而网口7(与MEU连接的编号为0号的MRU)分配到了12～19号GSM载波信号和0号宽带选频数据。在进行载波调度时，可以对24载波GSM信号进行重复调度，即与MEU连接的各个MRU，进行载波调度以后，每个MRU获得的载波信号可以全部相同，也可以部分相同。例如，编号为3的载波可以分配给网口0，也可以分配给其他与MEU连接的网口。As shown in Figure 8, WCDMA is divided into three 15M frequency selections to realize the scheduling of Ethernet service data signals. Assume three 15M broadband frequency-selective signals are numbered 1 to 3 in turn. The numbers of 24 carrier GSM signals are 0 to 23 in turn. As shown in Figure 8, it contains 8 carrier GSM signals and a 15M broadband frequency-selective signal. Therefore, each MRU can obtain at most 8 carrier GSM carrier signals and a 15M broadband frequency-selective signal. For example, in Figure 8, network port 0 (the MRU numbered 0 connected to the MEU) is assigned carrier signals 3-10 and broadband frequency selection data No. 2, while network port 7 (the number connected to the MEU is 0 The MRU) is allocated to No. 12-19 GSM carrier signals and No. 0 broadband frequency-selective data. During carrier scheduling, 24-carrier GSM signals can be repeatedly scheduled, that is, each MRU connected to the MEU, after carrier scheduling, each MRU can obtain the same carrier signal all or part of the same. For example, carrier number 3 can be assigned to network port 0, or to other network ports connected to the MEU.
在进行载波调度的过程中，调度原则可以根据组网的需求来设定，热点地区可以多分配些资源。例如，假设网口6处于商务区，在每天的10:00～18:00，用户比较多，相应地，在进行载波调度时，可以为网口6分配较多的载波信号。In the process of carrier scheduling, the scheduling principle can be set according to the requirements of the networking, and more resources can be allocated in hotspot areas. For example, assuming that network port 6 is located in a business district, there are many users from 10:00 to 18:00 every day. Correspondingly, during carrier scheduling, more carrier signals can be allocated to network port 6.
步骤705，将调度后的载波信号和以太网数据业务信号进行合并处理，形成基于以太网帧结构承载的传输信号，然后将形成的传输信号传输至对应的MRU。Step 705: Combine the scheduled carrier signal and the Ethernet data service signal to form a transmission signal based on the Ethernet frame structure, and then transmit the formed transmission signal to the corresponding MRU.
在上行链路中：In the uplink:
步骤706，接收至少一个MRU发来的基于以太网帧结构承载的传输信号。Step 706: Receive a transmission signal based on the Ethernet frame structure from at least one MRU.
步骤707，在接收到的传输信号中，对其数据帧结构进行解析处理，获得其中承载的数字基带信号和以太网数据业务信号。Step 707: Analyze and process the data frame structure of the received transmission signal to obtain the digital baseband signal and Ethernet data service signal carried therein.
步骤708，在获得的数字基带信号中确定出载波信号，并对重复的载波信号进行合路处理。
步骤709，将合路处理后的载波信号传输至MAU，将获得的以太网数据业务信号传输至以太网设备。
本发明实施例七这里提出的载波调度的方法，适合应用在楼宇密集型等热点地区，既能够满足通信网络大范围的覆盖、也能够在使得大容量的数据在采用直放站作为中继的室内分布式系统中的传输，同时支持灵活的组网方式，实现室内精确的覆盖，并且便于工程施工，节省工程建设的成本。能够较好地提高其覆盖区域的话务质量，提升用户的感知度。The carrier scheduling method proposed here in Embodiment 7 of the present invention is suitable for application in hotspot areas such as dense buildings, which can not only meet the wide coverage of the communication network, but also enable large-capacity data to use repeaters as relays. The transmission in the indoor distributed system also supports flexible networking methods to achieve accurate indoor coverage, facilitates engineering construction, and saves engineering construction costs. It can better improve the traffic quality in its coverage area and enhance the user's perception.
