技术领域technical field
本申请涉及通信技术领域,尤其涉及小区选择方法、装置及***。The present application relates to the technical field of communications, and in particular to a cell selection method, device and system.
背景技术Background technique
随着通信技术的发展,第五代移动通信技术(5th generation,5G)新无线(new radio,NR)引入了网络切片(network slicing)。其中,网络切片可以在保证用户的服务质量(quality of service,QoS)基础上,实现不同用户的隔离,从而保障用户的服务等级协议(service level agreement,SLA)。With the development of communication technology, the fifth generation mobile communication technology (5th generation, 5G) new radio (new radio, NR) introduces network slicing (network slicing). Among them, network slicing can realize the isolation of different users on the basis of ensuring the quality of service (QoS) of users, so as to guarantee the service level agreement (SLA) of users.
然而,在终端设备的移动过程中,终端设备接入的不同小区,其所属的网络切片的能力可能不同,例如支持的网络切片的类型不同,或者可分配给网络切片的资源不同等。如果正在运行某个切片业务的终端设备切换小区时,选择的目标小区所属的网络切片的能力不支持该切片业务,例如目标小区所属的网络切片的切片类型不支持该切片业务或者目标小区所属的网络切片的切片资源不足,则终端设备当前运行的切片业务的连续性不能保证。However, during the mobile process of the terminal device, different cells accessed by the terminal device may have different capabilities of the network slices to which they belong, for example, different types of supported network slices, or different resources that can be allocated to network slices, etc. If a terminal device that is running a slice service switches cells, the capability of the selected network slice to which the target cell belongs does not support the slice service, for example, the slice type of the network slice to which the target cell belongs does not support the slice service or the network slice to which the target cell belongs If the slicing resources of the network slicing are insufficient, the continuity of the slicing service currently running on the terminal device cannot be guaranteed.
目前的方案中,由终端设备原本接入的源小区,根据邻区所属的网络切片是否过载的信息,为终端设备选择用于切换的目标小区,但是该方案仅考虑了网络切片是否过载,确定出的目标小区可能无法满足终端设备运行的切片业务的需求。In the current scheme, the source cell originally accessed by the terminal device selects the target cell for handover for the terminal device according to whether the network slice to which the adjacent cell belongs is overloaded. However, this scheme only considers whether the network slice is overloaded. The selected target cell may not be able to meet the requirements of the slicing service run by the terminal device.
因此,如何使终端设备接入的目标小区满足终端设备运行的切片业务的需求,是目前亟待解决的问题。Therefore, how to make the target cell accessed by the terminal device meet the requirements of the slice service operated by the terminal device is an urgent problem to be solved at present.

具体实施方式detailed description
详细描述本申请实施例之前,为了便于理解本申请实施例的技术方案,首先给出本申请相关技术名词的简要介绍如下:Before describing the embodiment of the present application in detail, in order to facilitate the understanding of the technical solutions of the embodiment of the present application, a brief introduction of the relevant technical terms of the present application is given as follows:
1、网络切片:1. Network slicing:
网络切片就是将一个物理网络切割成多个虚拟的端到端的网络,每一个都可获得逻辑独立的网络资源,且各切片之间可相互隔离。因此,当某一个切片中产生错误或故障时,并不会影响其他切片。而5G***的网络切片,就是将5G网络切出多张虚拟网络,从而支持更多业务。目前,对应于5G网络的各个场景,网络切片包括增强型移动宽带(enhanced mobile broadband,eMBB)切片,高可靠和低延迟通信(ultra-reliable and low latency communications,uRLLC)切片和大规模机器类型通信(massive machine type communication,mMTC)切片等类型。Network slicing is to divide a physical network into multiple virtual end-to-end networks, each of which can obtain logically independent network resources, and each slice can be isolated from each other. Therefore, when an error or failure occurs in one slice, it does not affect other slices. The network slicing of the 5G system is to cut out multiple virtual networks from the 5G network to support more services. Currently, corresponding to various scenarios of 5G networks, network slicing includes enhanced mobile broadband (eMBB) slicing, ultra-reliable and low latency communications (uRLLC) slicing and large-scale machine type communication (massive machine type communication, mMTC) slices and other types.

在终端设备接入服务小区后,若满足终端设备进行小区切换的条件,例如终端设备移出了原先接入的服务小区的覆盖范围,或者服务小区的信号不好,为了保证终端设备当前业务的正常运行,第一网络设备需要在满足终端设备切换条件的邻小区中为终端设备选择进行切换的目标小区。本申请实施例中,将满足终端设备切换条件的邻小区称为第一邻小区。其中,满足终端设备切换条件的邻小区可以理解为终端设备可以进行切换的小区。终端设备进行切换后,终端设备与切换至的目标小区建立连接。After the terminal device accesses the serving cell, if the conditions for the terminal device to perform cell switching are met, for example, the terminal device moves out of the coverage of the originally accessed serving cell, or the signal in the serving cell is not good, in order to ensure the normal operation of the current service of the terminal device In operation, the first network device needs to select a handover target cell for the terminal device from neighboring cells meeting the handover condition of the terminal device.

为了第一网络设备确定目标小区,第一网络设备需要确定满足终端设备切换条件的第一邻小区。本申请实施例中,一种可能的方式中,第一网络设备确定满足终端设备切换条件的一个或多个第一邻小区,包括:第一网络设备接收来自终端设备的测量报告;其中,测量报告包括一个或多个第二邻小区的标识信息和第一信息;其中,第一信息用于表征第二邻小区的信号质量。第一网络设备根据一个或多个第二邻小区的标识信息和第一信息,在一个或多个第二邻小区中,确定满足终端设备切换条件的一个或多个第一邻小区。In order for the first network device to determine the target cell, the first network device needs to determine the first neighboring cell that satisfies the handover condition of the terminal device. In this embodiment of the present application, in a possible manner, the first network device determines one or more first neighboring cells that meet the handover condition of the terminal device, including: the first network device receives a measurement report from the terminal device; wherein, the measurement The report includes identification information of one or more second neighboring cells and first information; wherein, the first information is used to characterize the signal quality of the second neighboring cells. The first network device determines, among the one or more second neighboring cells, one or more first neighboring cells that meet the handover condition of the terminal device according to the identification information of the one or more second neighboring cells and the first information.

Neighboring cells, n may be a preset positive integer. Alternatively, the first network device may use the second neighboring cell whose signal quality exceeds a preset threshold as the first neighboring cell that satisfies the handover condition of the terminal device. There is no limitation on the manner in which the first neighboring cell that satisfies the handover condition of the terminal device is selected from all the second neighboring cells based on the first information.
第一网络设备根据第二邻小区的第一信息筛选出满足终端设备切换条件的邻小区后,可以根据筛选出的邻小区的标识信息,将与标识信息对应的邻小区确定为第一邻小区。After the first network device screens the neighboring cell that satisfies the handover condition of the terminal device according to the first information of the second neighboring cell, it may determine the neighboring cell corresponding to the identification information as the first neighboring cell according to the identification information of the filtered neighboring cell .
另一种可能的方式中,第一网络设备确定满足终端设备切换条件的一个或多个第 一邻小区,包括:第一网络设备接收来自终端设备的测量报告;其中,测量报告包括一个或多个第一邻小区的标识信息。第一网络设备根据一个或多个第一邻小区的标识信息确定一个或多个第一邻小区。In another possible manner, the first network device determining one or more first neighboring cells that meet the handover condition of the terminal device includes: the first network device receives a measurement report from the terminal device; wherein the measurement report includes one or more The identification information of the first neighboring cell. The first network device determines the one or more first neighboring cells according to the identification information of the one or more first neighboring cells.
该实现方式中,终端设备可以确定第一邻小区,并将第一邻小区的标识信息包括在发送给第一网络设备的测量报告中,第一网络设备在接收到终端设备上报的测量报告后,可以根据获取的小区的标识信息,将与标识信息对应的邻小区确定为第一邻小区。In this implementation, the terminal device may determine the first neighboring cell, and include the identification information of the first neighboring cell in the measurement report sent to the first network device. After the first network device receives the measurement report reported by the terminal device, , the neighbor cell corresponding to the identifier information may be determined as the first neighbor cell according to the acquired identifier information of the cell.
需要说明的是,上述两种第一网络设备确定第一邻小区的实现方式中,第二种实现方式中终端设备发送的测量报告中包括的第一邻小区,可以为第一种实现方式中终端设备发送的测量报告中包括的第二邻小区。换言之,第一种实现方式可以为在第二种实现方式的基础上,第一网络设备在终端设备发送的测量报告包括的邻小区中进一步筛选从而得到第一邻小区的实现方式。It should be noted that, in the above two implementation manners in which the first network device determines the first neighbor cell, the first neighbor cell included in the measurement report sent by the terminal device in the second implementation manner may be the first neighbor cell in the first implementation manner The second neighboring cell included in the measurement report sent by the terminal device. In other words, the first implementation manner may be based on the second implementation manner, in which the first network device further screens the neighboring cells included in the measurement report sent by the terminal device to obtain the first neighboring cell.
可以理解的是,如果终端设备要得到测量报告,终端设备需要对邻小区进行测量并得到测量结果。本申请实施例中,终端设备进行测量的邻小区是第一网络设备下发给终端设备的。因此,可选的,在第一网络设备接收来自终端设备的测量报告之前,本申请实施例提供的小区选择方法包括:第一网络设备确定一个或多个第三邻小区,第三邻小区为支持终端设备运行的切片业务的邻小区。第一网络设备将一个或多个第三邻小区的测量配置信息发送给终端设备;其中,一个或多个第三邻小区的测量配置信息用于终端设备对所述一个或多个第三邻小区进行测量。It can be understood that, if the terminal device wants to obtain a measurement report, the terminal device needs to measure neighboring cells and obtain a measurement result. In the embodiment of the present application, the neighbor cell that the terminal device measures is delivered to the terminal device by the first network device. Therefore, optionally, before the first network device receives the measurement report from the terminal device, the cell selection method provided in this embodiment of the present application includes: the first network device determines one or more third neighboring cells, and the third neighboring cells are Adjacent cells that support slice services run by terminal equipment. The first network device sends the measurement configuration information of one or more third neighboring cells to the terminal device; wherein, the measurement configuration information of the one or more third neighboring cells is used by the terminal device to measure the one or more third neighboring cells The area is measured.
具体地,第一网络设备可以根据终端设备运行的切片业务,确定出支持终端设备运行的切片业务的第三邻小区,并将第三邻小区的测量配置信息发送给终端设备。其中,第三邻小区的测量配置信息包括第三邻小区的小区ID和第三邻小区的频点信息。终端设备收到第三邻小区的测量配置信息后,可以根据第三邻小区的小区ID,确定要进行测量的邻小区,并可以根据与小区ID对应的频点信息,对频点信息所指示的频点进行测量,得到小区ID指示的第三邻小区的测量结果。Specifically, the first network device may determine a third neighboring cell that supports the slice service run by the terminal device according to the slice service run by the terminal device, and send measurement configuration information of the third neighboring cell to the terminal device. Wherein, the measurement configuration information of the third neighboring cell includes a cell ID of the third neighboring cell and frequency point information of the third neighboring cell. After receiving the measurement configuration information of the third neighboring cell, the terminal device can determine the neighboring cell to be measured according to the cell ID of the third neighboring cell, and can perform the frequency point information indicated by the frequency point information according to the frequency point information corresponding to the cell ID. The frequency point is measured, and the measurement result of the third neighboring cell indicated by the cell ID is obtained.
示例性的,第一网络设备可以通过无线资源控制(radio resource control,RRC)信令,例如RRC连接重配置(RRC_connection reconfiguartion)消息将第三邻小区的测量配置信息发送给终端设备。Exemplarily, the first network device may send the measurement configuration information of the third neighboring cell to the terminal device through radio resource control (radio resource control, RRC) signaling, such as an RRC_connection reconfiguration (RRC_connection reconfiguartion) message.
因为本方案中,第一网络设备先确定出支持终端设备运行的切片业务的邻小区,再将支持切片业务的邻小区下发给终端设备进行测量,终端设备无需测量不支持终端设备切片业务的邻小区,减少了终端设备的测量开销。进一步地,因为终端设备测量的邻小区都是支持终端设备切片业务的邻小区,可以理解的是,终端设备发送的测量报告指示的邻小区也均为支持终端设备切片业务的邻小区,第一网络设备根据终端设备发送的测量报告确定的第一邻小区也均为支持终端设备切片业务的邻小区,可以保证终端设备切换至的目标小区支持终端设备运行的切片业务,进而保证终端设备运行的切片业务的连续性。Because in this solution, the first network device first determines the neighboring cells that support the slicing service run by the terminal device, and then sends the neighboring cells that support the slicing service to the terminal device for measurement, and the terminal device does not need to measure the cells that do not support the slicing service of the terminal device. Neighboring cells reduce the measurement overhead of terminal equipment. Furthermore, because the adjacent cells measured by the terminal device are all adjacent cells that support the terminal device slice service, it can be understood that the adjacent cells indicated by the measurement report sent by the terminal device are also neighbor cells that support the terminal device slice service. The first neighboring cell determined by the network device according to the measurement report sent by the terminal device is also a neighboring cell that supports the slicing service of the terminal device, which can ensure that the target cell to which the terminal device is handed over supports the slicing service operated by the terminal device, thereby ensuring the operation of the terminal device. Slicing business continuity.

The third network device includes the second network device. The first network device may send the second information to the third network device through an interface with the third network device, such as an Xn interface, or the first network device through an interface with the core network, such as an N2 interface, and the second information uses To query the slice capability information of the fourth neighboring cell. After receiving the second information, the third network device sends the slice capability information of the fourth adjacent cell associated with it to the first network device in response to the second information. Correspondingly, the first network device receives the second information from the third network device. Slicing capability information of four adjacent cells.
另一种可能的实现方式中,第一网络设备接收来自操作维护管理功能模块OAM的第四邻小区的切片能力信息。In another possible implementation manner, the first network device receives the slice capability information of the fourth neighboring cell from the operation, maintenance and management function module OAM.

Alternatively, the OAM periodically sends the slice capability information of the fourth neighboring cell to the first network device. Or, the OAM sends the slice capability information of the fourth neighboring cell to the first network device according to the operation of the staff on the physical device integrated with the OAM.
需要说明的是,本申请实施例中,第一网络设备可以通过上述两种实现方式之一获取第四邻小区的切片能力信息,也可以结合上述两种实现方式(接收来自第三网络设备的第四邻小区的切片能力信息且接收来自OAM的第四邻小区的切片能力信息)来获取第四邻小区的切片能力信息,本申请实施例对此不做限制。It should be noted that, in this embodiment of the present application, the first network device may obtain slice capability information of the fourth neighboring cell through one of the above two implementation methods, or may combine the above two implementation methods (receiving the information from the third network device The slice capability information of the fourth neighbor cell and receiving the slice capability information of the fourth neighbor cell from the OAM) to obtain the slice capability information of the fourth neighbor cell, which is not limited in this embodiment of the present application.
需要说明的是,本申请实施例中,第一网络设备可以同时获取邻区列表和第四邻小区的切片能力信息,例如OAM向第一网络设备发送包括邻区列表和第四邻小区的切片能力信息的消息。第一网络设备还可以在获取邻区列表之后,再获取第四邻小区的切片能力信息,例如第一网络设备根据预配置的邻区列表确定第四邻小区后,向与第四邻小区关联的第三网络设备发送第二消息,再接收来自第三网络设备的第四邻小区的切片能力信息。It should be noted that, in this embodiment of the present application, the first network device can simultaneously obtain the slice capability information of the neighbor list and the fourth neighbor cell, for example, the OAM sends the slice including the neighbor list and the fourth neighbor cell to the first network device Capability information message. The first network device may also obtain the slicing capability information of the fourth neighboring cell after obtaining the neighboring cell list, for example, after the first network device determines the fourth neighboring cell according to the pre-configured The third network device sends the second message, and then receives the slice capability information of the fourth neighboring cell from the third network device.
其中,第四邻小区的切片能力信息包括第四邻小区是否支持网络切片和/或第四邻小区所属网络切片对应的切片类型。Wherein, the slicing capability information of the fourth neighboring cell includes whether the fourth neighboring cell supports network slicing and/or a slice type corresponding to the network slice to which the fourth neighboring cell belongs.

The cell serves as the third neighboring cell.
其中,因为第四邻小区的切片能力信息包括第四邻小区是否支持网络切片和/或第四邻小区所属网络切片对应的切片类型,第一网络设备获取到第四邻小区的切片能力信息后,可以根据终端设备运行的切片业务对应的切片类型,将所属网络切片对应的切片类型包括终端设备运行的切片业务对应的切片类型的第四邻小区,确定为第三邻小区。例如,某一第四邻小区的切片能力信息指包括该第四邻小区支持网络切片,该第四邻小区所属网络切片的类型包括eMBB类型和uRLLC类型,而终端设备运行的切片业务对应的切片类型为eMBB类型,因此该第四邻小区可以支持终端设备运行的切片业务,第一网络设备可以将该第四邻小区确定为第三邻小区。Wherein, since the slicing capability information of the fourth neighboring cell includes whether the fourth neighboring cell supports network slicing and/or the slice type corresponding to the network slice to which the fourth neighboring cell belongs, after the first network device obtains the slicing capability information of the fourth neighboring cell, According to the slice type corresponding to the slice service run by the terminal device, the fourth neighbor cell whose network slice corresponds to the slice type including the slice type corresponding to the slice service run by the terminal device may be determined as the third neighbor cell. For example, the slicing capability information of a fourth neighboring cell includes that the fourth neighboring cell supports network slicing, the type of network slice to which the fourth neighboring cell belongs includes eMBB type and uRLLC type, and the slice corresponding to the slice service run by the terminal device The type is eMBB, so the fourth neighboring cell can support the slice service run by the terminal device, and the first network device can determine the fourth neighboring cell as the third neighboring cell.

Wherein, the first calculation rule is used to calculate resources of the slice type corresponding to the network slice to which the first neighboring cell can be used by the first neighboring cell. Therefore, the second network device may determine, according to the first calculation rule and the first parameter set, that the associated first neighboring cell can use resources of a slice type corresponding to the network slice to which it belongs.
本申请实施例中,上述第一计算规则可以为预配置的数学模型或公式。In this embodiment of the present application, the foregoing first calculation rule may be a preconfigured mathematical model or formula.

Wherein, at least one of the slice quota type parameter, the slice quota proportion parameter, or the slice quota proportion balance parameter is associated with the slice type parameter.
以下对切片类型参数、切片配额类型参数、切片配额占比参数或者切片配额占比余量参数进行具体说明。The slice type parameter, the slice quota type parameter, the slice quota proportion parameter, or the slice quota proportion balance parameter are described in detail below.
切片类型参数,用于表征该参数定义的网络切片对应的切片类型,例如切片类型参数包括eMBB切片、uRLLC切片或mMTC切片等。The slice type parameter is used to represent the slice type corresponding to the network slice defined by this parameter. For example, the slice type parameter includes eMBB slice, uRLLC slice, or mMTC slice.
切片配额类型参数,用于表征被分配给该参数定义的网络切片的资源空闲时能否分配给其他切片。示例性的,以δ i,t表示第一邻小区i所属的网络切片中,切片类型为t的网络切片对应的切片配额类型参数。当δ i,t=0时,表示第一邻小区i将分配给切片类型t的网络切片的资源严格地分配给该参数所定义的切片进行使用,其他类型的网络切片不可以使用这些资源。 The slice quota type parameter is used to indicate whether the resources allocated to the network slice defined by this parameter can be allocated to other slices when they are idle. Exemplarily, δ i, t represents the slice quota type parameter corresponding to the network slice whose slice type is t in the network slice to which the first neighboring cell i belongs. When δ i,t =0, it means that the first neighboring cell i strictly allocates the resources allocated to the network slice of slice type t to the slice defined by this parameter for use, and other types of network slices cannot use these resources.
切片配额占比参数,用于表征第一邻小区分配给该参数定义的网络切片对应的切片类型的资源占第一邻小区小区总资源的百分比的阈值,其中,阈值可以为上限阈值(小区总资源的最大百分比),或者下限阈值(小区总资源的最小百分比)。例如,以ρ i,t表示第一邻小区i所属的网络切片中,切片类型为t的网络切片对应的切片配额占比参数,示例性的,ρ i,t表示最大百分比时,若ρ i,t=50%,表示第一邻小区i最多为切片类型为t的网络切片分配50%的小区总资源。 The slice quota ratio parameter is used to represent the threshold value of the percentage of the resource allocated by the first neighboring cell to the slice type corresponding to the network slice defined by this parameter in the total resources of the first neighboring cell, where the threshold can be an upper limit threshold (total maximum percentage of resources), or a lower threshold (minimum percentage of total cell resources). For example, let ρ i,t represent the slice quota ratio parameter corresponding to the network slice whose slice type is t in the network slice to which the first neighboring cell i belongs. For example, when ρ i,t represents the maximum percentage, if ρ i ,t = 50%, indicating that the first neighboring cell i allocates at most 50% of the total cell resources to the network slice whose slice type is t.
切片配额占比余量参数,用于表征该参数定义的网络切片对应的切片类型的最大或最小资源预留比率。示例性的,以
Figure PCTCN2022095368-appb-000001
表示第一邻小区i所属的网络切片中,切片类型为t的网络切片对应的切片配额占比余量参数,当ρ i,t指示的第一邻小区i为切片类型为t的网络切片分配的最大或最小百分比资源中,空闲资源(未使用的资源)大于由margin比率指示的资源量时,可以将ρ i,t指示的最大或最小百分比资源中的空闲资源与margin比率所配置的资源之差分配给其他类型的网络切片。为了便于理解,以一个具体的示例进行解释,若切片类型为t的网络切片当前占用第一邻小区小区i总资源的5%,且ρ i,t=50%,
Figure PCTCN2022095368-appb-000002
可知第一邻小区i为切片类型为t的网络切片分配的50%的资源中,该网络切片当前占用了50%中的5%,50%的分配资源中还有45%资源为空闲资源,因为45%大于40%,第一邻小区可以将这空闲的45%资源减去
Figure PCTCN2022095368-appb-000003
即5%分配给其他类型的网络切片使用。
The slice quota ratio margin parameter is used to represent the maximum or minimum resource reservation ratio of the slice type corresponding to the network slice defined by this parameter. Exemplary, with
Figure PCTCN2022095368-appb-000001
Indicates the slice quota ratio margin parameter corresponding to the network slice whose slice type is t in the network slice to which the first neighboring cell i belongs. When the first neighboring cell i indicated by ρ i,t is assigned to the network slice whose slice type is t When the maximum or minimum percentage of resources in ρi,t indicates that the idle resources (unused resources) are greater than the amount of resources indicated by the margin ratio, the resources configured by the maximum or minimum percentage of resources indicated by ρ i,t can be configured by the margin ratio The difference is allocated to other types of network slices. To facilitate understanding, a specific example is used to explain, if the network slice whose slice type is t currently occupies 5% of the total resources of the first neighbor cell i, and ρ i,t =50%,
Figure PCTCN2022095368-appb-000002
It can be seen that among the 50% resources allocated by the first neighboring cell i to the network slice whose slice type is t, the network slice currently occupies 5% of the 50%, and 45% of the 50% allocated resources are idle resources. Because 45% is greater than 40%, the first neighbor cell can subtract the idle 45% resources from
Figure PCTCN2022095368-appb-000003
That is, 5% is allocated to other types of network slice usage.
