Description
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to an interference coordination method, an interference coordination device and a base station.
Background
The 5G network supports 1000-time magnitude increase of traffic, the core technology is to deploy an ultra-dense network, and the cell radius is reduced by increasing the number of low-power sites so as to improve the transmission capability of unit area and improve the system capacity. In an ultra-dense network scene, the deployment density of stations is increased, and the distance between stations is reduced, which leads to more serious inter-cell interference. At the cell edge, the user rate and experience are difficult to be effectively improved. And as the number of neighboring stations increases, there may be multiple interferers of close strength, making the interference situation more complex. How to avoid inter-cell interference through site cooperation is an important problem to be solved by ultra-dense networks.
In time domain inter-cell interference coordination in an ultra-dense networking scene, the key point is to determine Almost Blank Subframe (ABS) patterns used by a base station to which an interfering cell belongs and a base station to which an interfered cell belongs. In a traditional mode, after an interfered base station to which an interfered cell belongs finds an interfering base station to which an interfering cell to a certain user belongs, according to a network quality condition fed back by the user, a time domain inter-cell interference coordination request is sent to the interfering base station, then the interfering base station sends an ABS pattern set to the interfered base station, the interfered base station selects an ABS pattern and feeds the ABS pattern back to the interfering base station for confirmation, and then resource scheduling is carried out based on the confirmed pattern; or the interfered base station directly sends an ABS pattern set to the interfering base station, and after the interfering base station selects one ABS pattern, the interfering base station and the interfered base station carry out resource scheduling based on the confirmed pattern. However, with the rapid development of mobile internet services and the rise of 5G + industry vertical services, there gradually appears a service type in which the demand for a network is regularly changed. For example, in a robot 4K video inspection service, after user equipment starts to operate, continuous 4K video live broadcasting is started, the requirement on a mobile network is fixed, that is, 4K video transmission is completed, and meanwhile, a mobile route which may change according to the design of service logic may exist in the robot. When the user equipment moves from one location to another location, a serving cell (i.e., an interfered cell) is switched by using a conventional ABS coordination manner, and at this time, the interfered base station to which the serving cell belongs and the interfering base station to which a new interfering cell belongs need to perform interference coordination again, but before that, the user equipment is subjected to new interference, so that data transmission is affected, and user experience is reduced.

Detailed Description
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 only a part of the embodiments of the present invention, and not all of the embodiments.
It should be noted that, in the embodiments of the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "such as" in an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.
The basic idea of inter-cell interference coordination is to coordinate the scheduling and allocation of resources among cells according to certain rules and methods to reduce inter-cell interference. In order to accomplish interference coordination between cells in time domain, the concept of ABS is introduced. For the 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 schedules the user at the position of these ABSs, thereby implementing inter-cell interference coordination in the time domain. When the user equipment moves from one location to another location, a serving cell (i.e., an interfered cell) is switched by using a conventional ABS coordination manner, and at this time, the interfered base station to which the serving cell belongs and the interfering base station to which a new interfering cell belongs need to perform interference coordination again, but before that, the user equipment is subjected to new interference, thereby affecting data transmission and reducing user experience.
Fig. 1 shows a diagram of a scenario of inter-cell interference. As shown in fig. 1, includes: the interfered base station 101, the interfering base station 102 and the user terminal 103 are configured such that the coverage area of the interfered base station 101 is an interfered cell 1011 and the coverage area of the interfering base station 102 is an interfering cell 1021. In the scenario of fig. 1, the interfered base station 101 serves the user terminal 103 to provide an interference signal to the user terminal 103, and the user terminal 103 is interfered by the interfering base station 102 to provide an interference signal to the user terminal 103. Here, it is to be noted that although one interfering cell 1021 associated with one interfering base station 102 is schematically shown in fig. 1, in other embodiments of the present invention, there may be a plurality of interfering base stations 102 and associated interfering cells 1021.
Based on the foregoing technical background and the problems existing 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 apparatus, where the interference coordination apparatus is an interfered base station or a chip in the interfered base station, and the method is performed by the interfered base station in the following example as an example, and the method includes:
201. the interfered base station confirms that the user equipment moves from the interfered cell to the interference cell, acquires the service type of the user equipment operation, and sends an almost blank subframe ABS pattern set and the service type to the interference base station; so that the interfering base station can confirm the usable ABS pattern in the ABS pattern set according to the traffic type.
Wherein, the signal of the interference base station covers the interference cell; the signal of the interfered base station covers the interfered cell.
Optionally, the confirming that the user equipment moves from the interfered cell to the interfering cell by the interfered base station specifically includes: and acquiring 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.
Optionally, the obtaining of the service type of the user equipment includes: acquiring service data, and identifying the service type of the user equipment according to the service data; wherein the traffic data comprises any one of: the service identifier, 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.
For example, the device for identifying the service type operated by the user equipment may be an interfered base station to which the interfered cell belongs, or may be an MEC server serving the interfered base station, and when the MEC server identifies the service type operated by the user equipment, the service type operated by the user equipment is sent to the interfered base station. The method for identifying the service type of the user equipment operation can be realized by negotiating with the user equipment or a specified service client on the user equipment, when the user equipment starts to perform a specified type service, the user equipment or the specified service client on the user equipment sends a specific identifier (such as a service identifier) to an interfered base station or an MEC server serving the user equipment, and the interfered base station or the MEC server identifies the service type of the user equipment operation by identifying the identifier; or the interfered base station or the MEC server may analyze the destination IP of the service data packet sent by the user equipment, the port number of the service data packet, and the domain name of the service data packet), and identify the service type of the user equipment. For example, the mobile robot, as a mobile device, sends a data packet with a specific identifier to indicate that a 4K mobile monitoring service with a specific coding format will be continuously performed subsequently according to negotiation with the MEC server, and the network bandwidth requirement is about 20Mbps.
In addition, after the interfered base station acquires the measurement report of the user equipment and determines that the user equipment moves from the interfered cell to the interfering cell according to the measurement report, the method further includes: and the interfered base station sends the measurement report and the identification of the user equipment to the interfering base station so that the interfering base station confirms that the service serving cell of the user equipment needs to be switched from the interfered cell to the interfering cell according to the measurement report and the identification of the user equipment.
It should be noted that, after receiving the measurement report of the user equipment according to the conventional handover procedure, the interfered base station determines that it is necessary to handover the user from the interfered cell to the interfering cell, and based on reciprocity of interference, when the initial interfered cell of the user is handed over to the interfering cell, the cell with the strongest interference is generally the current interfered cell. Therefore, when the interfered base station corresponding to the interfered cell sends a handover request message to the interfering base station or the mobile core network corresponding to the interfering cell, the interfered base station sends the identifier of the user equipment, the service type of the user equipment and the allowable ABS pattern set to the interfering base station. The identifier of the user equipment may be information such as IMEI, IP address, etc. of the equipment, and is used to uniquely indicate the user equipment. For example, when the service type of the user equipment is 4K mobile monitoring service with a specific coding format, the network bandwidth requirement is about 20Mbps.
202. And the interfered base station receives the ABS pattern returned by the interfering base station.
It should be noted that, the interfering base station determines, according to the obtained service type of the ue, the identifier of the ue, and the ue measurement report, the network resource that needs to be configured for the ue after the ue is handed over to the cell. For example, the network bandwidth requirement of 20Mbps requires that an interfering base station corresponding to an interfering cell and an interfered base station corresponding to an interfered cell negotiate to configure 3 ABS blank subframes for the service type of the user equipment; and then, according to the interference coordination condition with other cells and an allowable ABS pattern set sent by the interfered cell, an ABS pattern to be used after the user completes the switching is formulated.
203. After determining that the user equipment is switched from the interfered cell to the interference cell, the interfered base station performs subframe silencing at a corresponding position according to the ABS pattern; and the interference base station transmits the data of the service type at the corresponding position according to the ABS pattern.
Specifically, after determining that the user equipment is switched from the interfered cell to the interfering cell, the interfered base station performs subframe muting at a corresponding position according to the time set by the ABS pattern, so that the interfering base station performs data transmission of the service type at the corresponding position according to the time set by the ABS pattern. For example, data transmission of a certain service in the service type is performed within the time from xms to yms.
Optionally, when the ue completes handover, that is, after the interfered base station corresponding to the interfered cell receives a ue context release message sent by the interfering base station corresponding to the mobile core network or the interfering cell, the interfering cell becomes a serving cell of the user and provides a data transmission service for the user, and 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 a service type according to the negotiated ABS pattern.
In the above method, the user equipment is subject to new interference due to the handover of the serving cell being considered; therefore, after confirming that the serving cell of the user equipment is changed from the interfered cell to the interfering cell covered by the signal of the interfering base station, before the serving cell is switched, the ABS pattern set and the service type of the user equipment are acquired and sent to the interfering base station; receiving usable ABS patterns in the ABS pattern set confirmed by the interference base station according to the service type; then after determining that the user equipment is switched from the interfered cell to the interference cell, carrying out subframe silencing at a corresponding position according to the ABS pattern; therefore, the interference base station transmits the data of the service type at the corresponding position according to the ABS pattern, and the problems that the data transmission of the user equipment is influenced by newly generated interference and the user experience is reduced due to the fact that interference coordination is not performed in time after the service cell of the user equipment is switched are solved.

The integrated module can be realized in a hardware mode, and can also be realized in a software functional module mode.
