技术领域Technical field

本公开涉及移动通信技术领域，具体涉及一种通信方法、终端及基站。The present disclosure relates to the field of mobile communication technology, and in particular to a communication method, terminal and base station.

背景技术Background technique

在小区切换过程中，通常由源基站向目标基站发送切换准备消息，目标基站执行接纳控制，并回复切换命令。相关技术中，如果在切换过程中，目标基站不支持终端正在运行中的切片，会直接拒绝该切片，从而导致终端业务中断，影响用户业务体验。另外，在切换发生前，由于源基站并不知晓目标基站某切片的拥塞情况、资源预留、服务质量(QoS)回退等信息，因此可能在切换发生后才发现切片无法正常获得服务或者必须下降QoS才能获得最基本的服务，可能导致某些切片切换失败或影响用户体验。In the cell handover process, usually the source base station sends a handover preparation message to the target base station, and the target base station performs admission control and responds to the handover command. In the related art, if the target base station does not support the running slice of the terminal during the handover process, the slice will be directly rejected, which will cause the terminal service to be interrupted and affect the user's service experience. In addition, before the handover occurs, since the source base station does not know the congestion, resource reservation, quality of service (QoS) rollback and other information of a slice of the target base station, it may be discovered that the slice cannot normally obtain service or must be serviced after the handover occurs. The most basic services can only be obtained by lowering QoS, which may cause some slice switching failures or affect user experience.

类似地，在小区重选前，终端也并不知道服务小区/邻小区/邻频上该切片的拥塞情况、资源预留、服务质量(QoS)回退等信息，因此也有可能在小区重选之后，终端才发现无法接入目标小区，这种情况会影响小区重选的成功率，降低用户体验。Similarly, before cell reselection, the terminal does not know the congestion status, resource reservation, quality of service (QoS) rollback and other information of the slice on the serving cell/neighbor cell/neighbor frequency, so it is also possible to reselect the cell. After that, the terminal finds that it cannot access the target cell. This situation will affect the success rate of cell reselection and reduce user experience.

如背景技术中所述的，在相关技术中，终端可能在小区重选或接入后发生未预料到的小区无法接入、切片接入失败或切片QoS回退等情况，这严重影响了用户体验，为解决以上问题中的至少一个，本公开实施例提供了一种通信方法，可以减少或避免以上情况的发生，提高通信效率，改善用户体验。As described in the background art, in related technologies, unforeseen cell access failures, slice access failures, or slice QoS rollbacks may occur after the terminal is reselected or accessed, which seriously affects users. Experience. In order to solve at least one of the above problems, embodiments of the present disclosure provide a communication method, which can reduce or avoid the occurrence of the above situations, improve communication efficiency, and improve user experience.

请参照图2，本公开实施例提供的一种通信方法，在应用于终端侧时，包括：Referring to FIG. 2, a communication method provided by an embodiment of the present disclosure, when applied to a terminal side, includes:

步骤21，接收基站发送的至少一个小区的切片信息，所述切片信息包括切片负载信息、切片资源信息和切片服务质量中的至少一种。Step 21: Receive slice information of at least one cell sent by a base station, where the slice information includes at least one of slice load information, slice resource information, and slice service quality.

这里，基站可以向终端发送小区的切片信息，具体地，可以发送该小区的一个或多个切片的切片信息，所述小区可以是所述终端的驻留小区、服务小区或邻区中的一个或多个。所述基站可以是终端的服务小区所属的基站，即服务基站，服务基站可以通过***消息或专用信令，将上述切片信息发送给所述终端。在发送邻区的切片信息时，所述基站还可以在该邻区的切片信息中携带邻区的频点信息。邻区的切片信息可以通过基站间的信息交互获得，具体交互方式可以参考下文对图3以及图4的描述。Here, the base station may send the slicing information of the cell to the terminal, specifically, it may send the slicing information of one or more slices of the cell, and the cell may be one of the camping cell, serving cell, or neighboring cell of the terminal. Or more. The base station may be the base station to which the serving cell of the terminal belongs, that is, the serving base station, and the serving base station may send the slice information to the terminal through system messages or dedicated signaling. When sending the slice information of the neighboring cell, the base station may also carry the frequency information of the neighboring cell in the slice information of the neighboring cell. The slice information of the neighboring cells can be obtained through information exchange between base stations, and the specific interaction manner can refer to the description of FIG. 3 and FIG. 4 below.

根据本公开的至少一个实施例，所述切片负载信息为负载率或所述负载率所属的负载区间。例如，负载率可以采用百分比的形式，例如资源占用率20％等。负载区间可以是高、中、低若干档，用于指示该基站的某个切片负载情况是高、或中、或低负载。所述切片资源信息可以包括以下资源中的至少一种：预留的载波数、子载波数、带宽、传输资源块、符号以及时隙。所述切片服务质量信息可以包括用于指示在发生拥塞时将切片的服务质量回退的回退指示信息，其中，所述服务质量包括以下参数中的至少一种：5QI类别、时延、优先级或和速率等信息。其中，5QI是一个标量，可以用于索引 一个5G QoS特性。According to at least one embodiment of the present disclosure, the slice load information is a load rate or a load interval to which the load rate belongs. For example, the load rate can be in the form of a percentage, such as a resource occupancy rate of 20%. The load interval can be high, medium, or low, which is used to indicate whether the load of a certain slice of the base station is high, medium, or low. The slice resource information may include at least one of the following resources: the number of reserved carriers, the number of subcarriers, bandwidth, transmission resource blocks, symbols, and time slots. The slice quality of service information may include back-off indication information used to indicate that the quality of service of the slice is to be rolled back when congestion occurs, where the quality of service includes at least one of the following parameters: 5QI category, delay, priority Level or rate and other information. Among them, 5QI is a scalar, which can be used to index a 5G QoS feature.

步骤22，根据所述基站发送的至少一个小区的切片信息，进行小区重选或接入。Step 22: Perform cell reselection or access according to the slice information of at least one cell sent by the base station.

这里，终端可以根据基站发送的小区的切片信息进行小区重选或小区接入。这里，小区重选是指根据切片信息，对多个小区的相关参数进行排序，根据排序结果，从多个小区中重新选择终端的新驻留小区。小区接入通常是不经过重选选择的过程，而是直接接入某个小区。也就是说，在步骤22中，终端可以根据切片信息进行小区重选，选择某个相关参数排序最优的小区重新驻留，也可以直接根据某个小区的切片信息，接入该小区。例如，终端在某个切片上的切片信息满足预设质量要求时，可以直接接入该小区。Here, the terminal may perform cell reselection or cell access according to the slicing information of the cell sent by the base station. Here, cell reselection refers to sorting the relevant parameters of multiple cells according to the slice information, and reselecting the new camping cell of the terminal from the multiple cells according to the sorting result. Cell access usually involves direct access to a cell without going through a reselection process. That is to say, in step 22, the terminal may perform cell reselection according to the slice information, select a cell with the best ranking of related parameters to camp on again, or directly access the cell according to the slice information of a certain cell. For example, when the slice information of the terminal on a certain slice meets the preset quality requirement, it can directly access the cell.

通过以上步骤，本公开实施例通过服务小区提前告知终端相关切片信息(如反映了邻小区某个切片上的拥塞情况)，使得终端可以选择欲接入切片上相关参数满足预设要求(如负载最轻或满足预设质量要求)的频点或小区进行驻留或接入，从而可以减少或避免不期望的切片接入失败、小区接入识别或切片QoS回退情况的发生，提高终端的通信效率，改善用户的使用体验。Through the above steps, the embodiment of the present disclosure informs the terminal related slice information in advance through the serving cell (for example, reflecting the congestion condition on a certain slice of the neighboring cell), so that the terminal can select the relevant parameters on the slice to be accessed to meet the preset requirements (such as load The lightest frequency point or cell that meets the preset quality requirements) is camped on or accessed, thereby reducing or avoiding undesired slice access failures, cell access recognition or slice QoS fallback, and improving terminal performance. Communication efficiency improves user experience.

这里，在上述步骤22中，终端可以根据所述基站发送的至少一个小区的切片信息，从各个小区的第一类切片中选择目标切片，将所述目标切片对应的小区作为目标小区进行小区重选或接入，其中，所述第一类切片为所述终端支持的切片，或者为所述终端发起的业务所对应的切片。Here, in the above step 22, the terminal may select a target slice from the first-type slices of each cell according to the slice information of at least one cell sent by the base station, and use the cell corresponding to the target slice as the target cell for cell reconfiguration. Selection or access, wherein the first type of slice is a slice supported by the terminal, or a slice corresponding to a service initiated by the terminal.

具体地，终端可以按照以下任一方式来选择目标切片：Specifically, the terminal can select the target slice in any of the following ways:

1)根据第一类切片中各切片的切片负载信息，选择负载率最轻的切片，作为所述目标切片。1) According to the slice load information of each slice in the first type of slice, the slice with the lightest load rate is selected as the target slice.

2)根据第一类切片中各切片的切片资源信息，选择预留资源最高的切片，作为所述目标切片。2) According to the slice resource information of each slice in the first type of slice, the slice with the highest reserved resource is selected as the target slice.

3)根据第一类切片中各切片的切片负载信息和切片资源信息，选择空闲资源最高的切片，作为所述目标切片。3) According to the slice load information and slice resource information of each slice in the first type of slice, the slice with the highest free resource is selected as the target slice.

4)根据第一类切片中各切片的切片服务质量，选择服务质量回退程度最低的切片，作为所述目标切片。4) According to the slice service quality of each slice in the first type of slice, the slice with the lowest service quality regression is selected as the target slice.

5)从所述第一类切片中随机选择一个切片，作为所述目标切片。5) Randomly select a slice from the first type of slice as the target slice.

需要说明的是，以上选择目标切片时，上述切片信息可以是需要考虑的一种条件，本公开实施例还可以综合根据小区的信号质量以及上述切片信息等条件来进行综合决策。例如，可以先根据信号质量选择出排序靠前的至少一个的候选小区，然后针对所选择的候选小区，根据候选小区的切片信息，选择出目标切片，进行小区重选或接入。在选择目标切片时，可以按照上文类似的方式进行选择。It should be noted that when the target slice is selected above, the slice information may be a condition that needs to be considered, and the embodiment of the present disclosure may also comprehensively make a comprehensive decision based on the signal quality of the cell and the slice information and other conditions. For example, at least one candidate cell with the highest ranking may be selected according to the signal quality, and then for the selected candidate cell, the target slice may be selected according to the slice information of the candidate cell for cell reselection or access. When selecting a target slice, you can select it in a similar way as above.

另外，在所述第一类切片为所述终端发起的业务所对应的切片时，在重选到所述目标小区之后，所述终端可以在所述目标小区的第一类切片上发起随机接入，接入至所述第一类切片。In addition, when the first-type slice is a slice corresponding to the service initiated by the terminal, after reselecting to the target cell, the terminal may initiate a random connection on the first-type slice of the target cell. In, access to the first-type slice.

例如，小区1向终端发送本小区的切片信息，其中包括小区1在切片1上的切片负载信息为轻，或20％，小区1在切片2上的切片负载信息为重，或80％；另外，小区1还可以向终端发送邻区的切片信息，其中包括小区2在切片1上的负载为重，小区2在切片2上的负载为轻，同时发送小区2所在的频点2。终端在收到以上切片信息，后续当终端准备发起切片2的业务时，或者终端的无线资源控制(RRC)层从非接入层(NAS)层收到切片2的接入请求时，或终端准备恢复切片2的连接时(例如，之前已建过切片2的连接，但因终端进入去激活态而将切片2的连接挂起)，由于在切片2上小区2的负载相比于小区1要轻，因此，终端可以基于切片2的负载，先重选到小区2，然后再在小区2上发起接入，接入切片2。当然，终端也可以直接向小区2发起接入，接入切片2。For example, cell 1 sends the slice information of its own cell to the terminal, including that the slice load information of cell 1 on slice 1 is light, or 20%, and the slice load information of cell 1 on slice 2 is heavy, or 80%; Cell 1 can also send the slice information of the neighboring cells to the terminal, including that the load of cell 2 on slice 1 is heavy, and the load of cell 2 on slice 2 is light, and the frequency point 2 where cell 2 is located is sent at the same time. After the terminal receives the above slice information, when the terminal is ready to initiate the service of slice 2, or the radio resource control (RRC) layer of the terminal receives the access request of slice 2 from the non-access stratum (NAS) layer, or the terminal When preparing to restore the connection of slice 2 (for example, the connection of slice 2 has been established before, but the connection of slice 2 is suspended because the terminal enters the deactivated state), because the load of cell 2 on slice 2 is compared with that of cell 1. Therefore, the terminal can first reselect to cell 2 based on the load of slice 2, and then initiate access on cell 2 to access slice 2. Of course, the terminal can also directly initiate access to cell 2 to access slice 2.

又例如，以根据切片负载和切片资源选择目标切片为例，假设基站间交互切片的资源预留信息，包括预留的带宽，或子载波，或时隙资源。同时，基站间还可以交互切片负载信息，例如负载50％或80％。For another example, taking the selection of a target slice according to slice load and slice resources as an example, it is assumed that the resource reservation information of the slice is exchanged between base stations, including reserved bandwidth, or subcarriers, or time slot resources. At the same time, the base stations can also exchange slice load information, such as load 50% or 80%.

假设小区A为切片1预留了3MHz的带宽，负载为50％；小区B为切片1预留了5MHz的带宽，负载为80％。终端根据资源预留和负载，可以估算空余资源，小区A的切片1的空余资源为1.5MHz，小区B的切片1的空余资源为1MHz。可见小区A的切片1的空余资源要多于小区B。Assume that cell A reserves a bandwidth of 3 MHz for slice 1, and the load is 50%; cell B reserves a bandwidth of 5 MHz for slice 1, and the load is 80%. The terminal can estimate the vacant resources according to the resource reservation and load, the vacant resources of the slice 1 of the cell A are 1.5 MHz, and the vacant resources of the slice 1 of the cell B are 1 MHz. It can be seen that the free resources of slice 1 of cell A are more than that of cell B.

当终端准备发起切片1的业务时，或者终端的RRC层从NAS层收到切片1的接入请求时，或终端准备恢复切片1的连接时(之前已建起过切片1 的连接，但终端回到去激活态时，切片1的连接被挂起)，终端会先重选到切片预留资源较多或拥塞最轻的小区B，再在小区B上发起接入，接入切片1。When the terminal is ready to initiate the service of slice 1, or the RRC layer of the terminal receives the access request of slice 1 from the NAS layer, or the terminal is ready to resume the connection of slice 1 (the connection of slice 1 has been established before, but the terminal When returning to the deactivated state, the connection of slice 1 is suspended), the terminal will first reselect to cell B with more reserved resources or the least congestion on the slice, and then initiate access on cell B to access slice 1.

与图2所示流程相对应的，本公开实施例还提供了一种通信方法，如图3所示，在应用于基站侧时，包括：Corresponding to the process shown in FIG. 2, an embodiment of the present disclosure also provides a communication method. As shown in FIG. 3, when applied to the base station side, it includes:

步骤31，基站向终端发送至少一个小区的切片信息，所述切片信息包括切片负载信息、切片资源信息和切片服务质量中的至少一种，所述切片信息用于供所述终端进行小区重选或接入。Step 31: The base station sends slice information of at least one cell to the terminal, where the slice information includes at least one of slice load information, slice resource information, and slice service quality, and the slice information is used for the terminal to perform cell reselection. Or access.

所述基站可以是终端的服务小区所属的基站，即服务基站，服务基站可以通过***消息或专用信令，将上述切片信息发送给所述终端。在发送邻区的切片信息时，所述基站还可以在该邻区的切片信息中携带邻区的频点信息。The base station may be the base station to which the serving cell of the terminal belongs, that is, the serving base station, and the serving base station may send the slice information to the terminal through system messages or dedicated signaling. When sending the slice information of the neighboring cell, the base station may also carry the frequency information of the neighboring cell in the slice information of the neighboring cell.

具体地，所述基站可以向终端发送小区的切片信息，具体地，可以发送该小区的一个或多个切片的切片信息，所述小区可以是所述终端的驻留小区、服务小区或邻区中的一个或多个。Specifically, the base station may send the slicing information of the cell to the terminal, specifically, it may send the slicing information of one or more slices of the cell, and the cell may be the camping cell, serving cell or neighboring cell of the terminal. One or more of.

通过以上步骤，本公开实施例实现了基站与终端之间交互切片信息，从而为终端根据上述切片信息进行小区重选/接入提供了相关参考信息，可以减少或避免后续终端发生不期望的切片接入失败、小区接入识别或切片QoS回退等情况，提高终端的通信效率，改善用户的使用体验。Through the above steps, the embodiments of the present disclosure realize the exchange of slicing information between the base station and the terminal, thereby providing relevant reference information for the terminal to perform cell reselection/access based on the above slicing information, and can reduce or avoid subsequent undesired slicing of the terminal. Circumstances such as access failure, cell access recognition, or slice QoS fallback, improve the communication efficiency of the terminal and improve the user experience.

以上通信方法中，通过终端与基站之间的切片信息交互，使得终端可以根据基站发送的切片信息进行小区重选或接入，本公开实施例还可以通过在基站之间进行切片信息交互，使得终端的服务基站可以基于相邻基站/小区的切片信息，选择终端切换的目标小区，下面将结合附图对此进行详细说明。In the above communication method, through the slicing information exchange between the terminal and the base station, the terminal can perform cell reselection or access according to the slicing information sent by the base station. The embodiment of the present disclosure can also exchange slicing information between the base stations, so that The serving base station of the terminal can select the target cell for the terminal handover based on the slice information of the neighboring base stations/cells, which will be described in detail below with reference to the drawings.

请参照图4，本公开至少一个实施例提供了一种通信方法，应用于第一基站，所述第一基站为终端的服务基站，即所述终端的服务小区所属的基站。如图4所示，该方法包括：Referring to FIG. 4, at least one embodiment of the present disclosure provides a communication method applied to a first base station, where the first base station is a serving base station of a terminal, that is, a base station to which a serving cell of the terminal belongs. As shown in Figure 4, the method includes:

步骤41，第一基站接收第二基站发送的至少一个小区的切片信息，所述切片信息包括切片负载信息、切片资源信息和切片服务质量中的至少一种。Step 41: The first base station receives slice information of at least one cell sent by a second base station, where the slice information includes at least one of slice load information, slice resource information, and slice service quality.

这里，所述切片负载信息可以是负载率或所述负载率所属的负载区间。所述切片资源信息可以包括以下资源中的至少一种：预留的载波数、子载波数、带宽、传输资源块、符号以及时隙。所述切片服务质量信息可以包括用 于指示在发生拥塞时将切片的服务质量回退的回退指示信息，其中，所述服务质量包括以下参数中的至少一种：5QI类别、时延、优先级或和速率等信息。所述第二基站可以包括一个或多个。Here, the slice load information may be a load rate or a load interval to which the load rate belongs.

The second base station may include one or more.

上述第一基站与第二基站间交互的切片信息时，可以使用X2、Xn、S1或NG接口进行上述切片信息的交互，例如利用上述接口的负载均衡信令流程交互上述切片信息。另外，本公开实施例第一基站和第二基站之间也可以在X2、Xn、S1或NG接口的切换消息(如切换失败或切换完成或切换准备或切换命令消息)中携带上述切片信息，这样可以通过上述切换消息将上述切片信息发送给源基站或，目标基站以用于下一次切换过程中进行判断决策。这里，下一次切换与当前切换可能不是针对同一终端的切换。当然，本公开实施例还可以通过异***基站间信息交互的流程中携带上述切片信息，例如在4G基站与5G基站间的信息交互流程中携带。When the slice information is exchanged between the first base station and the second base station, the X2, Xn, S1, or NG interface may be used to exchange the slice information, for example, the load balancing signaling process of the interface is used to exchange the slice information. In addition, the first base station and the second base station in the embodiment of the present disclosure may also carry the above-mentioned slice information in the handover message (such as handover failure or handover complete or handover preparation or handover command message) of the X2, Xn, S1 or NG interface. In this way, the above-mentioned slice information can be sent to the source base station or the target base station through the above-mentioned handover message to be used for judgment and decision making in the next handover process. Here, the next handover and the current handover may not be for the same terminal. Of course, the embodiments of the present disclosure may also carry the above-mentioned slice information in the process of information exchange between base stations of different systems, for example, in the process of information exchange between 4G base stations and 5G base stations.

另外，第一、第二基站间可以是周期性的进行上述切片信息的交互，也可以在第二基站在发生下述情况时才向第一基站发送上述切片信息，这些情况可以包括但不限于：切片负载过载(超出负载门限)、切片资源低于预定资源门限以及切片服务质量指示的QoS回退导致QoS低于预设的服务质量门限等。In addition, the first and second base stations may periodically exchange the slice information described above, or the second base station may send the slice information to the first base station only when the following situations occur. These situations may include, but are not limited to: : Slice load overload (exceeding the load threshold), slice resources are lower than the predetermined resource threshold, and the QoS fallback indicated by the slice quality of service causes the QoS to be lower than the preset quality of service threshold, etc.

步骤42，第一基站根据所述第二基站发送的至少一个小区的切片信息，选择出终端切片的目标小区并进行小区切换。Step 42: The first base station selects the target cell of the terminal slice according to the slice information of at least one cell sent by the second base station and performs cell handover.

这里，第一基站可以根据所述第二基站发送的至少一个小区的切片资源信息，从各个小区的第一类切片中选择目标切片，将所述目标切片对应的小区作为目标小区，其中，所述第一类切片为所述终端支持的切片，或者为所述终端发起的业务所对应的切片。Here, the first base station may select a target slice from the first type of slices of each cell according to the slice resource information of at least one cell sent by the second base station, and use the cell corresponding to the target slice as the target cell, where: The first type of slice is a slice supported by the terminal, or a slice corresponding to a service initiated by the terminal.

具体地，所述第一基站可以按照以下方式来选择目标切片：Specifically, the first base station may select the target slice in the following manner:

1)根据第一类切片中各切片的切片负载信息，选择负载率最轻的切片，作为所述目标切片。1) According to the slice load information of each slice in the first type of slice, the slice with the lightest load rate is selected as the target slice.

2)根据第一类切片中各切片的切片资源信息，选择预留资源最高的切片，作为所述目标切片。2) According to the slice resource information of each slice in the first type of slice, the slice with the highest reserved resource is selected as the target slice.

3)根据第一类切片中各切片的切片负载信息和切片资源信息，选择空闲 资源最高的切片，作为所述目标切片。3) According to the slice load information and slice resource information of each slice in the first type of slice, the slice with the highest free resource is selected as the target slice.

4)根据第一类切片中各切片的切片服务质量，选择服务质量回退程度最低的切片，作为所述目标切片。4) According to the slice service quality of each slice in the first type of slice, the slice with the lowest service quality regression is selected as the target slice.

需要说明的是，以上选择目标切片时，上述切片信息可以是需要考虑的一种条件，本公开实施例还可以综合根据小区的信号质量以及上述切片信息等条件来进行综合决策。例如，可以先根据信号质量选择出排序靠前的至少一个的候选小区，然后针对所选择的候选小区，根据候选小区的切片信息，选择出目标切片，进行小区切换。在选择目标切片时，可以按照上文类似的方式进行选择。It should be noted that when the target slice is selected above, the slice information may be a condition that needs to be considered, and the embodiment of the present disclosure may also comprehensively make a comprehensive decision based on the signal quality of the cell and the slice information and other conditions. For example, at least one candidate cell with the highest ranking may be selected first according to the signal quality, and then for the selected candidate cell, the target slice is selected according to the slice information of the candidate cell, and the cell handover is performed. When selecting a target slice, you can select it in a similar way as above.

通过以上步骤，第一基站可以根据其他基站发送的切片信息，选择终端切换的目标小区，进而控制终端切换至目标小区，从而通过基站间交互彼此的切片信息(如拥塞情况、QoS回退等情况)，可以更好的辅助网络侧进行移动性管理(如切换判决)以及资源调度等，避免小区切换后才发生未预料到的切片接入失败或切片QoS回退等情况，改善终端的通信效率，提升用户体验。Through the above steps, the first base station can select the target cell for terminal handover according to the slicing information sent by other base stations, and then control the terminal to handover to the target cell, so as to exchange each other's slice information (such as congestion, QoS fallback, etc.) between the base stations. ), it can better assist the network side in mobility management (such as handover decision) and resource scheduling, etc., to avoid unexpected slice access failure or slice QoS fallback after cell handover, and improve the communication efficiency of the terminal , Improve user experience.

以根据邻区的切片负载选择目标小区为例，在切换时，源基站(第一基站)可以根据邻基站(第二基站)的切片的负载情况选择目标小区所属的基站(即目标基站)。Taking the selection of the target cell based on the slice load of the neighboring cell as an example, during handover, the source base station (the first base station) can select the base station to which the target cell belongs (ie, the target base station) according to the load condition of the slice of the neighboring base station (the second base station).

示例a：假设源基站获知多个邻基站(或小区)的切片的负载信息，例如邻基站A的切片1高负载、邻基站A的切片2低负载，邻基站B的切片1低负载、邻基站B的切片2高负载。如果有某个终端在做切片1的业务，而根据终端的测量报告，基站A和B的信号强度相近，此时源基站可以优先将邻基站B作为目标基站。Example a: Suppose the source base station knows the load information of the slices of multiple neighboring base stations (or cells). For example, the slice 1 of neighboring base station A has high load, the slice 2 of neighboring base station A has low load, and the slice 1 of neighboring base station B has low load and neighboring base station. Slice 2 of base station B is highly loaded. If a certain terminal is doing the service of slice 1, and according to the measurement report of the terminal, the signal strengths of base stations A and B are similar, at this time, the source base station can preferentially use the neighboring base station B as the target base station.

示例b：假设终端同时运行切片1和切片2，且基站A和B的信号强度相近，则网络侧可根据切片优先级选择切换的目标基站，例如切片1优先级高于切片2，则优先将切片1低负载的基站作为目标基站。Example b: Assuming that the terminal runs slice 1 and slice 2 at the same time, and the signal strengths of base stations A and B are similar, the network side can select the target base station for handover according to the slice priority. For example, if the priority of slice 1 is higher than that of slice 2, it will give priority to Slice 1 low-load base station as the target base station.

以根据邻区的切片服务质量选择目标小区为例，在切换时，源基站(第一基站)可以根据邻基站(第二基站)的切片服务质量选择目标小区所属的基站(即目标基站)。Taking the selection of the target cell based on the slice service quality of the neighboring cell as an example, during handover, the source base station (the first base station) can select the base station to which the target cell belongs (ie, the target base station) according to the slice service quality of the neighboring base station (the second base station).

示例c：假设基站A和基站B都支持切片1，但由于基站B的切片1拥塞，需要将切片1的QoS回退，例如5QI从5回退到6，或者将时延从1ms回退到10ms，或者速率从100Mbps回退到10Mbps等。本公开实施例通过基站间交互切片的QoS回退信息，这样基站在为连接态终端选择切换的目标基站时，可以考虑到切片在目标基站预期可获得的服务，即切片1在基站A可以获得正常的服务，但在切片B却要做切片回退。在基站A和基站B同等信号强度下，服务基站将优先把基站A作为目标基站。具体地，服务基站可以先根据信号质量选择出排序靠前的至少一个的候选小区，然后针对所选择的候选小区，根据候选小区的切片服务质量，选择预期服务质量更优的目标切片所对应的小区，进行小区切换。Example c: Assume that both base station A and base station B support slice 1, but due to the congestion of slice 1 of base station B, the QoS of slice 1 needs to be rolled back, for example, 5QI is rolled back from 5 to 6, or the delay is rolled back from 1ms to 10ms, or the rate falls back from 100Mbps to 10Mbps, etc. In the embodiment of the present disclosure, the QoS fallback information of the slice is exchanged between the base stations, so that when the base station selects the target base station for handover for the connected terminal, it can consider the services expected to be available for the slice at the target base station, that is, slice 1 can be obtained at base station A Normal service, but slice B has to be sliced back. When base station A and base station B have the same signal strength, the serving base station will give priority to base station A as the target base station. Specifically, the serving base station may first select at least one candidate cell with the highest ranking according to the signal quality, and then for the selected candidate cell, according to the slice service quality of the candidate cell, select the target slice corresponding to the expected better service quality Cell, cell handover.

与图4所示流程相对应的，本公开实施例还提供了一种通信方法，如图5所示，在应用于第二基站侧时，包括：Corresponding to the process shown in FIG. 4, an embodiment of the present disclosure also provides a communication method. As shown in FIG. 5, when applied to the second base station side, it includes:

A base station performs cell handover.

这里，第二基站与第一基站间交互的切片信息时，可以使用X2、Xn、S1或NG接口进行上述切片信息的交互，例如利用上述接口的负载均衡信令流程交互上述切片信息。另外，本公开实施例第二基站和第一基站之间也可以在X2、Xn、S1或NG接口的切换消息(如切换失败或切换完成或切换准备或切换命令消息)中携带上述切片信息，这样可以通过上述切换消息将上述切片信息发送给源基站或，目标基站以用于下一次切换过程中进行判断决策。这里，下一次切换与当前切换可能不是针对同一终端的切换。当然，本公开实施例还可以通过异***基站间信息交互的流程中携带上述切片信息，例如在4G基站与5G基站间的信息交互流程中携带。Here, when the second base station exchanges slice information with the first base station, the X2, Xn, S1, or NG interface can be used to exchange the slice information, for example, the load balancing signaling process of the interface is used to exchange the slice information. In addition, the second base station and the first base station in the embodiment of the present disclosure may also carry the above-mentioned slice information in the handover message (such as handover failure or handover complete or handover preparation or handover command message) of the X2, Xn, S1 or NG interface. In this way, the above-mentioned slice information can be sent to the source base station or the target base station through the above-mentioned handover message to be used for judgment and decision making in the next handover process. Here, the next handover and the current handover may not be for the same terminal. Of course, the embodiments of the present disclosure may also carry the above-mentioned slice information in the process of information exchange between base stations of different systems, for example, in the process of information exchange between 4G base stations and 5G base stations.

另外，第二基站可以是周期性的发送上述切片信息，也可以在第二基站在发生下述情况时才向第一基站发送上述切片信息，这些情况可以包括但不限于：切片负载过载(超出负载门限)、切片资源低于预定资源门限以及切片服务质量指示的QoS回退导致QoS低于预设的服务质量门限等。In addition, the second base station may periodically send the above-mentioned slice information, or the second base station may send the above-mentioned slice information to the first base station only when the following situations occur. These conditions may include, but are not limited to: slice load overload (overload Load threshold), slice resources are lower than the predetermined resource threshold, and the QoS fallback indicated by the slice quality of service causes the QoS to be lower than the preset quality of service threshold.

通过以上步骤，本公开实施例实现了基站间进行切片信息的交互，可以 辅助基站进行小区切换，避免小区切换后才发生未预料到的切片接入失败或切片QoS回退等情况，改善终端的通信效率，提升用户体验。Through the above steps, the embodiments of the present disclosure realize the exchange of slice information between base stations, which can assist the base station in cell handover, avoid unexpected slice access failures or slice QoS rollbacks after cell handover, and improve terminal performance.
