本发明的实施例涉及通信技术领域，尤其涉及一种干扰协调方法及装置、基站。Embodiments of the present invention relate to the field of communication technologies, and in particular, to an interference coordination method and device, and a base station.
背景技术Background technique
5G网络要支持业务量1000倍量级的增长，核心技术是部署超密集网络，通过增加低功率站点数量，减小小区半径，以提高单位面积的传输能力，提升系统容量。超密集网络场景下，站点部署密度增加，站点之间距离减少，将导致更严重的小区间干扰。在小区边缘，用户速率和体验难以有效提升。并且由于邻近站点增加，可能存在多个强度接近的干扰源，使干扰情况更为复杂。如何通过站点协作，避免小区间干扰，是超密集网络需解决的一个重要问题。The 5G network needs to support a 1,000-fold increase in business volume. The core technology is to deploy an ultra-dense network. By increasing the number of low-power sites and reducing the radius of the cell, the transmission capacity per unit area is improved and the system capacity is increased. In an ultra-dense network scenario, the density of site deployment increases and the distance between sites decreases, which will lead to more serious inter-cell interference. At the edge of the cell, it is difficult to effectively improve the user rate and experience. And due to the increase of adjacent stations, there may be multiple interference sources with similar strengths, which makes the interference situation more complicated. How to avoid inter-cell interference through site cooperation is an important problem to be solved in ultra-dense networks.
超密集组网场景下的时域小区间干扰协调，关键是需要确定干扰小区所属基站和被干扰小区所属基站使用的几乎空白子帧(almost blank subframe，ABS)图样。传统的方式，是通过被干扰小区所属的被干扰基站发现对某个用户的干扰小区所属的干扰基站后，根据用户反馈的网络质量情况，向干扰基站发送时域小区间干扰协调请求，之后干扰基站向被干扰基站发送ABS图样集，由被干扰基站选择一个ABS图样后反馈给干扰基站以确认，并后续基于确认的图样进行资源调度；或被干扰基站直接向干扰基站发送ABS图样集，由干扰基站选择一个ABS图样后，干扰基站和被干扰基站基于确认的图样进行资源调度。然而，随着移动互联网业务的迅速发展以及5G+垂直行业业务的兴起，逐渐出现对网络需求有规律性变化的业务类型。例如机器人4K视频巡检业务，当用户设备开始作业后，就开始持续的4K视频直播，其对移动网络的需求较为固定，即完成4K视频传输，同时机器人根据业务逻辑的设计可能存在变化的移动路线。使用传统的ABS协调方式，当用户设备从一个位置移动到另一个位置时，导致服务小区(即被干扰小区)发生切换，此时就需要服务小区所属的被干扰基站和新的干扰小区所属的干扰基站重新进行干扰协调，但在此之前，用户设备已经受到新的干扰，从而影响数据传输，降低用户的体验。The key to inter-cell interference coordination in the time domain in an ultra-dense networking scenario is to determine the almost blank subframe (ABS) patterns used by the base station to which the interfering cell belongs and the base station to which the interfered cell belongs. The traditional method is to find the interfering base station of the interfering cell belonging to a certain user through the interfered base station of the interfered cell, and send a time-domain inter-cell interference coordination request to the interfering base station according to the network quality feedback from the user, and then interfere The base station sends an ABS pattern set to the interfered base station, and the interfered base station selects an ABS pattern and feeds it back to the interfering base station for confirmation, and then performs resource scheduling based on the confirmed pattern; or the interfered base station directly sends the ABS pattern set to the interfering base station, and the After the interfering base station selects an ABS pattern, the interfering base station and the interfered base station perform resource scheduling based on the confirmed pattern. However, with the rapid development of mobile Internet services and the rise of 5G+ vertical industry services, business types that have regular changes in network requirements have gradually emerged. For example, in the robot 4K video inspection service, when the user equipment starts to work, it will start continuous 4K video live broadcast. Its demand for mobile networks is relatively fixed, that is, to complete 4K video transmission. At the same time, the robot may move according to the design of the business logic. route. Using the traditional ABS coordination method, when the user equipment moves from one location to another, the serving cell (that is, the interfered cell) is handed over. The interfering base station re-performs interference coordination, but before that, the user equipment has already received new interference, thereby affecting data transmission and degrading user experience.

小区间干扰协调的基本思想是小区间按照一定的规则和方法，协调资源的调度和分配，以降低小区间干扰。为了在时域上完成小区间的干扰协调，引入了ABS的概念。对于ABS，只包含一些必要寻呼或系统消息信号，且配置的功率很低，从而在干扰小区所属的干扰基站中配置ABS，而被干扰小区所属的被干扰基站则在这些ABS的位置上对用户进行调度，从而实现时域上的小区间干扰协调。使用传统的ABS协调方式，当用户设备从一个位置移动到另一个位置时，导致服务小区(即被干扰小区)发生切换，此时就需要服务小区所属的被干扰基站和新的干扰小区所属的干扰基站重新进行干扰协调，但在此之前，用户设备已经受到新的干扰，从而影响数据传输，降低用户的体验。The basic idea of inter-cell interference coordination is that cells coordinate resource scheduling and allocation according to certain rules and methods, so as to reduce inter-cell interference. In order to complete interference coordination between cells in the time domain, the concept of ABS is introduced. For ABS, only some necessary paging or system message signals are included, and the configured power is very low, so that the ABS is configured in the interfering base station to which the interfering cell belongs, and the interfered base station to which the interfered cell belongs is for the position of these ABSs Users perform scheduling to implement inter-cell interference coordination in the time domain. Using the traditional ABS coordination method, when the user equipment moves from one location to another, the serving cell (that is, the interfered cell) is handed over. The interfering base station re-performs interference coordination, but before that, the user equipment has already received new interference, thereby affecting data transmission and degrading user experience.
图1示出了一种小区间干扰的场景图。如图1所示，包括：被干扰基站101、干扰基站102以及用户终端103，被干扰基站101的覆盖区域为被干扰小区1011，干扰基站102覆盖的区域为干扰小区1021。在图1的场景中，被干扰基站101服务用户终端103，为用户终端103提供干扰信号，用户终端103受到干扰基站102的干扰，为用户终端103提供干扰信号。在此，需要指出，虽然图1中示意性地示出了一个干扰基站102相关联的一个干扰小区1021，但是在本发明的其他实施例中，可以存在多个干扰基站102和相关联的干扰小区1021。Fig. 1 shows a scene diagram of inter-cell interference. As shown in FIG. 1 , it includes: an interfered base station 101, an interfering base station 102, and a user terminal 103. The coverage area of the interfered base station 101 is the interfered cell 1011, and the area covered by the interfering base station 102 is the interfering cell 1021. In the scenario in FIG. 1 , the interfered base station 101 serves the user terminal 103 and provides an interference signal for the user terminal 103 , and the user terminal 103 is interfered by the interfering base station 102 and provides the user terminal 103 with an interference signal. Here, it should be pointed out that although FIG. 1 schematically shows an interfering cell 1021 associated with one interfering base station 102, in other embodiments of the present invention, there may be multiple interfering base stations 102 and associated interfering cells. District 1021.
基于上述技术背景以及现有技术中存在的问题，参照图2，本发明实施例提供一种干扰协调方法，应用于干扰协调装置，该干扰协调装置为被干扰基站或者被干扰基站中的芯片，以下示例中以被干扰基站执行该方法为例进行说明，该方法包括：Based on the above technical background and the existing problems in the prior art, referring to FIG. 2 , an embodiment of the present invention provides an interference coordination method, which is applied to an interference coordination device. The interference coordination device is an interfered base station or a chip in the interfered base station. In the following example, the interfered base station is used as an example to illustrate the method, and the method includes:
201、被干扰基站确认用户设备从被干扰小区移动至干扰小区，则获取用户设备运行的业务类型，并将几乎空白子帧ABS图样集以及业务类型发送至干扰基站；以便干扰基站根据业务类型确认ABS图样集中可使用的ABS图样。201. The interfered base station confirms that the user equipment moves from the interfered cell to the interfering cell, then obtains the service type operated by the user equipment, and sends the almost blank subframe ABS pattern set and the service type to the interfering base station; so that the interfering base station confirms according to the service type Available ABS patterns in the ABS Pattern Collection.
其中，干扰基站的信号覆盖干扰小区；被干扰基站的信号覆盖被干扰小区。Wherein, the signal of the interfering base station covers the interfering cell; the signal of the interfered base station covers the interfered cell.
可选的，被干扰基站确认用户设备从被干扰小区移动至干扰小区，具体包括：获取用户设备的测量报告，并根据测量报告确定用户设备从被干扰小区移动至干扰小区。Optionally, the interfered base station confirming that the user equipment moves from the interfered cell to the interfering cell specifically includes: obtaining a measurement report of the user equipment, and determining that the user equipment moves from the interfered cell to the interfering cell according to the measurement report.
可选的，获取用户设备运行的业务类型，具体包括：获取业务数据，并根据业务数据识别用户设备运行的业务类型；其中业务数据包括以下的任一项：业务标识、业务数据包的目的IP、业务数据包的端口号以及业务数据包的域名。Optionally, obtaining the service type operated by the user equipment specifically includes: obtaining service data, and identifying the service type operated by the user equipment according to the service data; wherein the service data includes any of the following: service identifier, destination IP address of the service data packet , the port number of the service data packet, and the domain name of the service data packet.
示例性的，执行识别用户设备运行的业务类型的设备，可以是被干扰小区所属的被干扰基站，也可以是服务于该被干扰基站的MEC服务器，当由MEC服务器识别出用户设备运行的业务类型，并将用户设备运行的业务类型发送至被干扰基站。识别用户设备运行的业务类型的方法，可以通过与用户设备或用户设备上的指定业务客户端协商，当用户设备开始进行指定类型业务时，用户设备或用户设备上的指定业务客户端向服务于该用户设备的被干扰基站或MEC服务器发送特定标识(如业务标识)，前述被干扰基站或MEC服务器通过识别该标识识别用户设备运行的业务类型；也可以通过被干扰基站或MEC服务器解析用户设备发送业务数据包的目的IP、业务数据包的端口号以及业务数据包的域名)，识别用户设备运行的业务类型。例如，移动机器人作为移动设备，根据与MEC服务器的协商，发送带有特定标识的数据包指示后续将持续开展特定编码格式的4K移动监控业务，网络带宽需求约为20Mbps。Exemplarily, the device for identifying the type of service operated by the user equipment may be the interfered base station to which the interfered cell belongs, or the MEC server serving the interfered base station. When the MEC server identifies the service type operated by the user equipment type, and send the type of service run by the user equipment to the interfered base station. The method for identifying the type of service run by the user equipment can be negotiated with the user equipment or the specified service client on the user equipment. The interfered base station or MEC server of the user equipment sends a specific identifier (such as a service identifier), and the aforementioned interfered base station or MEC server identifies the type of service operated by the user equipment by identifying the identifier; the user equipment can also be resolved by the interfered base station or MEC server send the destination IP of the service data packet, the port number of the service data packet and the domain name of the service data packet), and identify the service type run by the user equipment. For example, a mobile robot, as a mobile device, sends a data packet with a specific identifier to indicate that it will continue to carry out 4K mobile monitoring services in a specific encoding format according to the negotiation with the MEC server, and the network bandwidth requirement is about 20Mbps.
另外，被干扰基站获取用户设备的测量报告，并根据测量报告确定用户设备从被干扰小区移动至干扰小区之后，还包括：被干扰基站将测量报告与用户设备的标识发送至干扰基站，以便干扰基站根据测量报告以及用户设备的标识确认用户设备的业务服务小区需从被干扰小区切换至干扰小区。In addition, after the interfered base station obtains the measurement report of the user equipment, and determines according to the measurement report that the user equipment moves from the interfered cell to the interfered cell, it also includes: the interfered base station sends the measurement report and the identity of the user equipment to the interfering base station, so that the interference The base station confirms that the serving cell of the user equipment needs to be handed over from the interfered cell to the interfering cell according to the measurement report and the identifier of the user equipment.
需要说明的是，被干扰基站按照常规切换流程，接收用户设备的测量报告后，判定需要将用户由被干扰小区切换到干扰小区，基于干扰的互易性，用户最初的被干扰小区切换到干扰小区时，对其干扰最强的一般是当前的被干扰小区。因此，在被干扰小区对应的被干扰基站向干扰小区对应的干扰基站或移动核心网发送切换请求消息时，被干扰基站将用户设备的标识、用户设备的业务类型及可允许使用的ABS图样集发送给干扰基站。其中，用户设备的标识可以是设备的IMEI、IP地址等信息，用来唯一的指示该用户设备。例如当用户设备的业务类型为特定编码格式的4K移动监控业务，网络带宽需求约为20Mbps。It should be noted that the interfered base station determines that the user needs to be handed over from the interfered cell to the interfering cell after receiving the measurement report of the user equipment according to the conventional handover process. In the case of a cell, the one with the strongest interference is generally the currently interfered cell. Therefore, when the interfered base station corresponding to the interfered cell sends a handover request message to the interfering base station corresponding to the interfering cell or the mobile core network, the interfered base station sends the identity of the user equipment, the service type of the user equipment, and the set of ABS patterns that can be used sent to the interfering base station. Wherein, the identifier of the user equipment may be information such as IMEI and IP address of the equipment, and is used to uniquely indicate the user equipment. For example, when the service type of the user equipment is a 4K mobile monitoring service in a specific encoding format, the network bandwidth requirement is about 20 Mbps.
202、被干扰基站接收干扰基站返回的ABS图样。202. The interfered base station receives the ABS pattern returned by the interfered base station.
需要说明的是，干扰基站根据上述获取的用户设备的业务类型、用户设备的标识以及用户测量报告判定该用户切换到本小区后需为其配置的网络资源。例如，20Mbps的网络带宽需求需要干扰小区对应的干扰基站与被干扰小区对应的被干扰基站协商为用户设备的业务类型配置3个ABS空白子帧；再根据与其他小区进行干扰协调情况及被干扰小区发送的允许使用的ABS图样集，制定用户完成切换后要使用的ABS图样。It should be noted that the interfering base station determines the network resources that need to be configured for the user after switching to the current cell according to the service type of the user equipment obtained above, the identity of the user equipment, and the user measurement report. For example, the network bandwidth requirement of 20Mbps requires that the interfering base station corresponding to the interfering cell and the interfered base station corresponding to the interfered cell negotiate to configure 3 ABS blank subframes for the service type of the user equipment; and then according to the interference coordination with other cells and the interfered The set of permitted ABS patterns sent by the cell is used to formulate the ABS patterns to be used by the user after the handover is completed.
203、被干扰基站在确定用户设备从被干扰小区切换至干扰小区后，根据ABS图样进行对应位置的子帧静默；使得干扰基站根据ABS图样在对应位置进行业务类型的数据传输。203. After determining that the user equipment is handed over from the interfered cell to the interfering cell, the interfered base station performs subframe muting at the corresponding location according to the ABS pattern; making the interfering base station perform service type data transmission at the corresponding location according to the ABS pattern.
具体的，被干扰基站在确定用户设备从被干扰小区切换至干扰小区后，根据ABS图样设定的时间进行对应位置的子帧静默，使得干扰基站根据ABS图样设定的时间在对应位置进行业务类型的数据传输。例如，在xms～yms的时间内进行该业务类型中某一项业务的数据传输。Specifically, after determining that the user equipment is handed over from the interfered cell to the interfering cell, the interfered base station performs subframe silence at the corresponding position according to the time set in the ABS pattern, so that the interfering base station performs service at the corresponding position according to the time set in the ABS pattern type of data transfer. For example, the data transmission of a certain service in the service type is performed within the time of xms˜yms.
可选的，当用户设备完成切换，即被干扰小区对应的被干扰基站收到来自移动核心网或干扰小区对应的干扰基站发送的用户设备上下文释放消息后，干扰小区成为用户的服务小区为用户提供数据传输服务，被干扰小区对应的被干扰基站和干扰小区对应的干扰基站按照上述协商的ABS图样进行业务类型的数据传输或者资源调度。Optionally, when the handover of the user equipment is completed, that is, after the interfered base station corresponding to the interfered cell receives the user equipment context release message sent by the mobile core network or the interfering base station corresponding to the interfering cell, the interfering cell becomes the serving cell of the user. To provide data transmission services, the interfered base station corresponding to the interfered cell and the interfering base station corresponding to the interfering cell perform data transmission or resource scheduling of service types according to the above negotiated ABS pattern.
在上述方法中，由于考虑到服务小区的切换导致用户设备受到新的干扰；因此，在确认用户设备的服务小区由被干扰小区转变为干扰基站的信号覆盖的干扰小区后，在服务小区发生切换之前，通过将ABS图样集以及获取用户设备运行的业务类型发送至干扰基站；并接收干扰基站根据业务类型确认ABS图样集中可使用的ABS图样；然后在确定用户设备从被干扰小区切换至干扰小区后，根据ABS图样进行对应位置的子帧静默；使得干扰基站根据ABS图样在对应位置进行业务类型的数据传输，从而解决在用户设备的服务小区发生切换后，由于未及时进行干扰协调，导致新产生的干扰影响用户设备的数据传输，降低用户的体验的问题。In the above method, due to consideration of the switching of the serving cell, the user equipment is subject to new interference; therefore, after confirming that the serving cell of the user equipment has changed from the interfered cell to the interfering cell covered by the signal of the interfering base station, the handover occurs in the serving cell Previously, by sending the ABS pattern set and obtaining the service type operated by the user equipment to the interfering base station; and receiving the interfering base station to confirm the available ABS patterns in the ABS pattern set according to the service type; and then determining that the user equipment is handed over from the interfered cell to the interfering cell Finally, perform subframe silence at the corresponding position according to the ABS pattern; make the interfering base station perform data transmission of the service type at the corresponding position according to the ABS pattern, so as to solve the problem that the interference coordination is not performed in time after the serving cell of the user equipment is handed over. The generated interference affects the data transmission of the user equipment and reduces the user experience.
