- eMBB still aims for users to obtain multimedia content, services and data, and its demand is growing rapidly.
- eMBB may be deployed in different scenarios, such as indoors, urban areas, rural areas, etc., its capabilities and requirements are also quite different, so it cannot be generalized and must be analyzed in detail in conjunction with specific deployment scenarios.
- Typical applications of URLLC include: industrial automation, power automation, telemedicine operations (surgery), traffic safety protection, etc.
- Typical features of mMTC include: high connection density, small data volume, delay-insensitive services, low-cost modules and long service life.
- the New Rational (NR) system supports the handover process of connected terminal devices.
- a terminal device that is using network services moves from one cell to another, or due to wireless transmission service load adjustment, activation operation and maintenance, equipment failure, etc., in order to ensure communication continuity and service quality, the system must The communication link between the terminal equipment and the original cell is transferred to the new cell, that is, the handover process is performed.
- the cell handover process as shown in Figure 1, is divided into the following three stages:
- Phase 1 including steps 1 to 5
- handover preparation including measurement control and reporting, handover request and confirmation
- Phase 2 (including steps 6 to 8), handover execution: the terminal device immediately executes the handover process after receiving the handover command, that is, the terminal device disconnects the source cell and connects to the target cell (such as performing random access, sends an RRC handover complete message to Target network equipment, etc.); secondary node (Secondary Node, SN) state transfer, data forwarding.
- the terminal device immediately executes the handover process after receiving the handover command, that is, the terminal device disconnects the source cell and connects to the target cell (such as performing random access, sends an RRC handover complete message to Target network equipment, etc.); secondary node (Secondary Node, SN) state transfer, data forwarding.
- SN Secondary Node
- Phase 3 (including steps 9 to 12), the handover is completed: the target cell and the (Acess and Mobility Management Function, AMF) and the user plane function (User Plane Function, UPF) execute the path switch (Path Switch), and release the terminal of the source network device Device context.
- AMF Access and Mobility Management Function
- UPF User Plane Function
- the source network device can initiate handover preparation or request messages for multiple target cells simultaneously or sequentially according to the measurement report of the terminal device (including measurement results of multiple cells); specifically, the source network device can be based on direct connection Or through the S1/N2 interface between the mobility management entity (Mobility Management Entity, MME)/AMF to initiate a handover preparation or request message.
- MME Mobility Management Entity
- each target cell After receiving the handover preparation/request message, each target cell performs access control according to its own RRM algorithm, and sends a handover request response message to the network device where the source cell is located under the premise of passing the access control (if the access control fails) Then respond to the handover request failure message), which carries the handover command generated by the target cell.

- the handover process triggered by the measurement report of the terminal equipment is mainly the management of the mobile connection of the terminal equipment by the network equipment, so that the terminal equipment maintains the continuity of the current transmission service when it moves to the cell boundary and enters a new cell.
- LTE and NR systems also support a blind handover process.
- One of the trigger conditions for blind handover is based on the load balancing considerations on the network side. For example, when the current serving cell is congested, the serving cell can switch one or more connected terminal devices to other cells with lower load, even if these terminals The device has not really moved to the cell boundary.
- the existing X2 and Xn interfaces already support the exchange of load information of respective cells between different base stations, so that the serving cell can obtain the load status of other neighboring cells and decide whether to perform blind handover to some terminal devices according to their respective load comparisons.
- conditional handover conditional handover
- the terminal device executes the handover to the target cell according to the pre-configured handover command (that is, triggers the random access process) when it is triggered by the conditions related to the target cell. And send a handover complete message) to avoid the problem of too late or unable to send measurement reports and receive handover commands due to high-speed movement into the poor coverage area.
- the source network device cannot predict which target network device the terminal device will initiate a cell handover to when the handover trigger condition is met; at this time, if the source network device forwards data to multiple target network devices, additional networks will be created Overhead; if the source network device waits for the terminal device to access the target cell, and then forwards the data to the target network device after receiving an instruction sent by the target network device, it will be due to the random access channel (Random Access Channel, RACH) in the conditional handover. ) The process causes a large data interruption delay, which affects the user experience.

为了能够更加详尽地了解本发明实施例的特点和技术内容,下面结合附图对本发明实施例的实现进行详细阐述,所附附图仅供参考说明之用,并非用来限定本发明实施例。In order to understand the features and technical content of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The attached drawings are for reference and explanation purposes only, and are not used to limit the embodiments of the present invention.
在对本发明实施例提供的数据转发方法进行详细说明之前,先对相关技术小区切换过程及小区切换后的数据转发方法进行简要说明。Before describing in detail the data forwarding method provided by the embodiment of the present invention, a brief description of the cell handover process in the related art and the data forwarding method after the cell handover will be briefly described.
当前,随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性和复杂性,3GPP国际标准组织开始研发5G。5G的主要应用场景为:增强移动超宽带(Enhance Mobile Broadband,eMBB)、低时延高可靠通信(Ultra Reliable Low Latency Communications,URLLC)、和大规模机器类通信(Massive Machine Type Communication,mMTC)。At present, with people's pursuit of speed, delay, high-speed mobility, energy efficiency, and the diversity and complexity of services in future life, the 3GPP International Standards Organization has begun to develop 5G. The main application scenarios of 5G are: Enhance Mobile Broadband (eMBB), Ultra Reliable Low Latency Communications (URLLC), and Massive Machine Type Communication (mMTC).
eMBB仍然以用户获得多媒体内容、服务和数据为目标,其需求增长十分迅速。另一方面,由于eMBB可能部署在不同的场景中,便如室内,市区,农村等,其能力和需求的差别也比较大,所以不能一概而论,必须结合具体的部署场景详细分析。URLLC的典型应用包括:工业自动化,电力自动化,远程医疗操作(手术),交通安全保障等。mMTC的典型特点包括:高连接密度,小数据量,时延不敏感业务,模块的低成本和长使用寿命等。eMBB still aims for users to obtain multimedia content, services and data, and its demand is growing rapidly. On the other hand, because eMBB may be deployed in different scenarios, such as indoors, urban areas, rural areas, etc., its capabilities and requirements are also quite different, so it cannot be generalized and must be analyzed in detail in conjunction with specific deployment scenarios. Typical applications of URLLC include: industrial automation, power automation, telemedicine operations (surgery), traffic safety protection, etc. Typical features of mMTC include: high connection density, small data volume, delay-insensitive services, low-cost modules and long service life.
与LTE***相似,新无线(New Ration,NR)***支持连接态终端设备的切换过程。当正在使用网络服务的终端设备从一个小区移动到另一个小区,或由于无线传输业务负荷量调整、激活操作维护、设备故障等原因,为了保证通信的连续性和服务的质量,***要将该终端设备与原小区的通信链路转移到新的小区上,即执行切换过程。Similar to the LTE system, the New Rational (NR) system supports the handover process of connected terminal devices. When a terminal device that is using network services moves from one cell to another, or due to wireless transmission service load adjustment, activation operation and maintenance, equipment failure, etc., in order to ensure communication continuity and service quality, the system must The communication link between the terminal equipment and the original cell is transferred to the new cell, that is, the handover process is performed.
以Xn接口切换过程为例,小区切换过程,如图1所示,分为以下三个阶段:Taking the Xn interface handover process as an example, the cell handover process, as shown in Figure 1, is divided into the following three stages:
阶段1(包括步骤1至5),切换准备:包括测量控制和汇报,切换请求以及确认Phase 1 (including steps 1 to 5), handover preparation: including measurement control and reporting, handover request and confirmation
阶段2(包括步骤6至8),切换执行:终端设备在收到切换命令后立即执行切换过程,即终端设备断开源小区并与目标小区连接(如执行随机接入,发送RRC切换完成消息给目标网络设备等);辅节点(Secondary Node,SN)状态转移,数据转发。Phase 2 (including steps 6 to 8), handover execution: the terminal device immediately executes the handover process after receiving the handover command, that is, the terminal device disconnects the source cell and connects to the target cell (such as performing random access, sends an RRC handover complete message to Target network equipment, etc.); secondary node (Secondary Node, SN) state transfer, data forwarding.
阶段3(包括步骤9至12),切换完成:目标小区与(Acess and Mobility Management Function,AMF)和用户面功能(User Plane Function,UPF)执行路径切换(Path Switch),释放源网络设备的终端设备上下文。Phase 3 (including steps 9 to 12), the handover is completed: the target cell and the (Acess and Mobility Management Function, AMF) and the user plane function (User Plane Function, UPF) execute the path switch (Path Switch), and release the terminal of the source network device Device context.
在网络实现上,源网络设备可以根据终端设备的测量上报(包含多个小区的测量结果),针对多个目标小区同时或先后发起切换准备或请求消息;具体地,源网络设备可以基于直连的X2/Xn接口,或者通过移动管理实体(Mobility Management Entity,MME)/AMF之间的S1/N2接口发起切换准备或请求消息。每个目标小区在收到切换准备/请求消息后根据自己的RRM算法进行接入控制,并在通过接入控制的前提下向源小区所在网络设备发送切换请求应答消息(如接入控制未通过则响应切换请求失败消息),其中携带目标小区生成的切换命令。源网络设备根据自己的RRM算法在返回切换应答的多个目标小区中选择一个作为最终的切换目标小区,并将与该目标小区对应的切换命令通过RRC重配置消息发送给终端设备,进而实现网络设备对切换过程的完全控制。In terms of network implementation, the source network device can initiate handover preparation or request messages for multiple target cells simultaneously or sequentially according to the measurement report of the terminal device (including measurement results of multiple cells); specifically, the source network device can be based on direct connection Or through the S1/N2 interface between the mobility management entity (Mobility Management Entity, MME)/AMF to initiate a handover preparation or request message. After receiving the handover preparation/request message, each target cell performs access control according to its own RRM algorithm, and sends a handover request response message to the network device where the source cell is located under the premise of passing the access control (if the access control fails) Then respond to the handover request failure message), which carries the handover command generated by the target cell. The source network device selects one of the multiple target cells that return a handover response according to its own RRM algorithm as the final handover target cell, and sends the handover command corresponding to the target cell to the terminal device through the RRC reconfiguration message to realize the network The device has complete control over the switching process.
由终端设备测量上报触发的切换过程主要是网络设备针对终端设备的移动性连接的管理,使得终端设备在移动到小区边界及进入到新的小区时保持当前传输业务的连续性。与这种切换触发条件不同,LTE和NR***还支持盲切换过程。盲切换的其中一种触发条件是基于网络侧的负载均衡考虑,例如当前服务小区如发生拥塞时,服务小区可以将一个或多个连接状态终端设备切换到其它负荷较低的小区,即使这些终端设备并没有真正移动到小区边界。现有的X2和Xn接口已支持在不同基站之间交互各自小区的负荷信息,使得服务小区可以获得其它相邻小区的负荷情况并根据各自负荷对比来决定是否对部分终端设备进行盲切换。The handover process triggered by the measurement report of the terminal equipment is mainly the management of the mobile connection of the terminal equipment by the network equipment, so that the terminal equipment maintains the continuity of the current transmission service when it moves to the cell boundary and enters a new cell. Unlike this handover trigger condition, LTE and NR systems also support a blind handover process. One of the trigger conditions for blind handover is based on the load balancing considerations on the network side. For example, when the current serving cell is congested, the serving cell can switch one or more connected terminal devices to other cells with lower load, even if these terminals The device has not really moved to the cell boundary. The existing X2 and Xn interfaces already support the exchange of load information of respective cells between different base stations, so that the serving cell can obtain the load status of other neighboring cells and decide whether to perform blind handover to some terminal devices according to their respective load comparisons.
针对高速移动场景和高频部署场景存在频繁切换以及切换容易失败的问题,3GPP当前正在讨论为LTE和NR***引入基于条件触发的切换(conditional handover)。conditional handover流程,如图2所示,终端设备根据网络设备配置的条件,在评估与目标小区相关的条件触发时按照预先配置好的切换命令执行向该目标小区的切换(即触发随机接入过程和发送切换完成消息),避免由于高速移动进入覆盖差区域来不及或无法发送测量上报和接收到切换命令的问题。conditional handover中,源网络设备无法预测终端设备在切换触发条件满足时,向哪个目标网络设备发起小区切换;此时,若源网络设备向多个目标网络设备都进行数据转发,会造成额外的网络开销;若源网络设备待终端设备接入目标小区后,接收到目标网络设备发送的指示后再向目标网络设备进行数据转发,则会由于conditional handover中的随机接入信道(Random Access Channel,RACH)过程造成较大的数据中断时延,影响用户体验。For high-speed mobile scenarios and high-frequency deployment scenarios, there are frequent handovers and handover problems that are prone to failure. 3GPP is currently discussing the introduction of conditional handover (conditional handover) for LTE and NR systems. The conditional handover process is shown in Figure 2. According to the conditions configured by the network equipment, the terminal device executes the handover to the target cell according to the pre-configured handover command (that is, triggers the random access process) when it is triggered by the conditions related to the target cell. And send a handover complete message) to avoid the problem of too late or unable to send measurement reports and receive handover commands due to high-speed movement into the poor coverage area. In conditional handover, the source network device cannot predict which target network device the terminal device will initiate a cell handover to when the handover trigger condition is met; at this time, if the source network device forwards data to multiple target network devices, additional networks will be created Overhead; if the source network device waits for the terminal device to access the target cell, and then forwards the data to the target network device after receiving an instruction sent by the target network device, it will be due to the random access channel (Random Access Channel, RACH) in the conditional handover. ) The process causes a large data interruption delay, which affects the user experience.

本发明实施例提供的应用于终端设备的数据转发方法的一种可选处理流程,如图4所示,包括以下步骤:An optional processing flow of the data forwarding method applied to terminal equipment provided by the embodiment of the present invention, as shown in FIG. 4, includes the following steps:
步骤S201,终端设备接收第一信息,所述第一信息用于指示所述终端设备在满足第一条件时,向源网络设备发送第一指示信息。Step S201: The terminal device receives first information, where the first information is used to instruct the terminal device to send first instruction information to the source network device when the first condition is met.
在一些实施例中,所述第一条件为网络设备为终端设备配置conditional handover的切换命令时,为终端设备配置的conditional handover时,源网络设备向目标网络设备转发数据的条件;所述第一条件与基于条件触发的切换conditional handover的源小区和/或目标小区的参数相关,所述目标小区与所述目标网络设备相对应,所述源小区与所述源网络设备相对应。其中,所述网络设备为当前为终端设备服务的源网络设备,或者所述网络设备为之前为终端设备服务的网络设备。In some embodiments, the first condition is a condition for the source network device to forward data to the target network device when a conditional handover is configured for the terminal device when the network device configures a conditional handover command for the terminal device; The condition is related to the parameters of the source cell and/or the target cell of the conditional handover based on the conditional handover, the target cell corresponds to the target network device, and the source cell corresponds to the source network device. Wherein, the network device is a source network device currently serving the terminal device, or the network device is a network device previously serving the terminal device.
可选地,与第一条件相关的基于条件触发的切换conditional handover的源小区和/或目标小区的参数为:源小区和/或目标小区的信号质量。Optionally, the parameters of the source cell and/or the target cell of the conditional handover based on the conditional handover related to the first condition are: signal quality of the source cell and/or the target cell.
以第一条件与目标小区的参数相关为例,第一条件为:所述目标小区的信号质量大于第一门限值。其中,所述第一门限值为A***的门限值;或者,所述第一门限值为所述源网络设备配置的A***的门限值与第一相对值之和,所述源网络设备配置的A***为触发所述终端设备执行conditional handover的事件。可选地,所述第一相对值为负值。举例来说,源网络设备配置的A***的门限值为3,第一相对值为-2,则所述第一门限值为1。当目标小区的信号质量大于1时,终端设备便向源网络设备发送第一指示信息。Taking the correlation between the first condition and the parameters of the target cell as an example, the first condition is: the signal quality of the target cell is greater than the first threshold. Wherein, the first threshold value is the threshold value of the A4 event; or, the first threshold value is the sum of the threshold value of the A4 event configured by the source network device and a first relative value, the The A4 event configured by the source network device is an event that triggers the terminal device to perform conditional handover. Optionally, the first relative value is a negative value. For example, if the threshold value of the A4 event configured by the source network device is 3 and the first relative value is -2, then the first threshold value is 1. When the signal quality of the target cell is greater than 1, the terminal device sends the first indication information to the source network device.
以第一条件与目标小区和源小区的参数相关为例,第一条件为:所述目标小区的信号质量与所述源小区的信号质量之差大于第二门限值。其中,所述第二门限值为A3事件的门限值;或者所述第二门限值为所述源网络设备配置的A3事件的门限值与第二相对值之和,所述源网络设备配置的A3事件为触发所述终端设备执行conditional handover的事件。可选地,所述第二相对值为负值。Taking the correlation between the first condition and the parameters of the target cell and the source cell as an example, the first condition is that the difference between the signal quality of the target cell and the signal quality of the source cell is greater than a second threshold. Wherein, the second threshold value is the threshold value of the A3 event; or the second threshold value is the sum of the threshold value of the A3 event configured by the source network device and a second relative value, and the source The A3 event configured by the network device is an event that triggers the terminal device to perform conditional handover. Optionally, the second relative value is a negative value.
以第一条件与源小区的参数相关为例,第一条件为:所述源小区的信号质量小于第三门限值,所述目标小区的信号质量大于第四门限值。其中,所述第三门限值和第四门限值为A5事件的门限值;或者所述第三门限值和第四门限值为所述源网络设备配置的A5事件的门限值与第三相对值之和,所述源网络设备配置的A5事件为触发所述终端设备执行conditional handover的事件。可选地,所述第三相对值为负值。举例来说,对应源网络设备配置的A5事件的两个门限值的第三相对值相同,所述源网络设备配置的A5事件的门限值分别是3和5,第三相对值为-2,则第三门限值为1,第四门限值为3。在具体实施时,对应源网络设备配置的A5事件的两个门限值的第三相对值也可以不同,如所述源网络设备配置的A5事件的门限值分别是3和5,对应源网络设备配置的A5事件的两个门限值的第三相对值分别为-2和-3,则第三门限值为1,第四门限值为2。Taking the correlation between the first condition and the parameters of the source cell as an example, the first condition is: the signal quality of the source cell is less than the third threshold value, and the signal quality of the target cell is greater than the fourth threshold value. Wherein, the third threshold value and the fourth threshold value are threshold values of the A5 event; or the third threshold value and the fourth threshold value are the threshold values of the A5 event configured by the source network device The sum of the value and the third relative value, the A5 event configured by the source network device is an event that triggers the terminal device to perform conditional handover. Optionally, the third relative value is a negative value. For example, the third relative value of the two thresholds corresponding to the A5 event configured by the source network device is the same, the thresholds of the A5 event configured by the source network device are 3 and 5 respectively, and the third relative value is − 2, then the third threshold is 1, and the fourth threshold is 3. In specific implementation, the third relative value of the two thresholds corresponding to the A5 event configured by the source network device may also be different. For example, the thresholds of the A5 event configured by the source network device are 3 and 5 respectively, corresponding to the source The third relative values of the two thresholds of the A5 event configured by the network device are -2 and -3, respectively, so the third threshold is 1, and the fourth threshold is 2.
以第一条件与源小区的参数相关为例,第一条件为:所述源小区的信号质量小于第五门限值。其中,所述第五门限值为A2事件的门限值;或者,所述第五门限值为所述源网络设备配置的A2事件的门限值与第四相对值之和,所述源网络设备配置的A2事件为触发所述终端设备执行conditional handover的事件。可选地,所述第四相对值为负值。如此,终端设备在与源网络设备之间的链路信号不好时(或者终端设备与源网络设备之间的链路即将断开、尚且能够进行通信时)发送第一指示信息给源网络设备;终端设备可以同时上报终端设备对至少一个目标网络设备的测量结果,如信道质量;使得源网络设备根据终端设备上报的测量结果,选择信号质量最好的一个或几个目标网络设备进行数据转发。此时,源网络设备认为终端设备即将向信号质量好的目标网络设备切换。Taking the correlation between the first condition and the parameters of the source cell as an example, the first condition is: the signal quality of the source cell is less than the fifth threshold. Wherein, the fifth threshold value is the threshold value of the A2 event; or, the fifth threshold value is the sum of the threshold value of the A2 event configured by the source network device and the fourth relative value, the The A2 event configured by the source network device is an event that triggers the terminal device to perform conditional handover. Optionally, the fourth relative value is a negative value. In this way, when the link signal between the terminal device and the source network device is not good (or the link between the terminal device and the source network device is about to be broken and communication is still possible), the terminal device sends the first indication information to the source network device ; The terminal device can report the measurement results of the terminal device on at least one target network device at the same time, such as channel quality; make the source network device select one or several target network devices with the best signal quality for data forwarding according to the measurement results reported by the terminal device . At this time, the source network device thinks that the terminal device is about to switch to the target network device with good signal quality.
本发明实施例中,第一相对值、第二相对值、第三相对值和第四相对值均可以是由源网络设备通过无线资源控制(Radio Resource Control,RRC)信令配置给终端设备。In the embodiment of the present invention, the first relative value, the second relative value, the third relative value, and the fourth relative value may all be configured by the source network device to the terminal device through radio resource control (Radio Resource Control, RRC) signaling.
基于上述第一条件与不同的参数相关时,所述第一条件还包括:所述源小区的信号 质量大于第六门限值。使得终端设备能够在源小区信号质量好的时候向源网络设备上报第一指示信息,即源网络设备能够接收到终端设备发送的第一指示信息。Based on the foregoing first condition being related to different parameters, the first condition further includes: the signal quality of the source cell is greater than a sixth threshold. This enables the terminal device to report the first indication information to the source network device when the signal quality of the source cell is good, that is, the source network device can receive the first indication information sent by the terminal device.
本发明实施例中,所述信号质量包括下述中的至少一种:参考信道接收功率(Reference Signal Receiving Power,RSRP)、参考信号接收质量(Reference Signal Receiving Quality,RSRQ)、和信噪比(Signal to Noise Ratio,SNR)。In the embodiment of the present invention, the signal quality includes at least one of the following: Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), and Signal to Noise Ratio (RSRP) Signal to Noise Ratio, SNR).
上述对第一条件进行了相应的说明。在满足第一条件时,终端设备向源网络设备发送第一指示信息,所述第一指示信息用于指示所述源网络设备向目标网络设备转发数据。源网络设备在接收到第一指示信息后,判断终端设备即将向目标小区发起切换;源网络设备按照第一指示信息中的内容向目标网络设备进行数据转发;在切换触发条件满足时,终端设备发起向目标小区的切换。由于在切换触发条件满足前,终端设备便向源网络设备发送第一指示信息,使得源网络设备能够及时的向目标网络设备转发数据,避免conditional handover中较大的数据终端时延,提高用户体验。The first condition is explained above. When the first condition is met, the terminal device sends first indication information to the source network device, where the first indication information is used to instruct the source network device to forward data to the target network device. After receiving the first instruction information, the source network device determines that the terminal device is about to initiate handover to the target cell; the source network device forwards data to the target network device according to the content in the first instruction information; when the handover trigger condition is met, the terminal device Initiate a handover to the target cell. Before the handover trigger condition is met, the terminal device sends the first indication information to the source network device, so that the source network device can forward data to the target network device in time, avoiding the large data terminal delay in conditional handover and improving user experience .
在一些实施例中,所述第一指示信息由终端设备通过RRC信令、或媒体接入控制(Media Access Control,MAC)信令或物理层信令发送至源网络设备。所述第一指示信息包括:目标小区的编号信息,和/或目标小区的频点和物理小区标识(Physical Cell Identifier,PCI)。源网络设备根据目标小区的编号信息,和/或目标小区的频点和PCI,能够确定终端设备切换到哪个目标小区以及对应的目标网络设备;源网络设备向所确定的目标网络设备转发数据。如此,通过终端设备向源网络设备发送第一指示信息,能够缩小源网络设备向目标网络设备进行数据转发的范围,节省了信令开销。In some embodiments, the first indication information is sent by the terminal device to the source network device through RRC signaling, or Media Access Control (MAC) signaling or physical layer signaling. The first indication information includes: serial number information of the target cell, and/or frequency and physical cell identifier (Physical Cell Identifier, PCI) of the target cell. The source network device can determine which target cell the terminal device switches to and the corresponding target network device according to the number information of the target cell, and/or the frequency and PCI of the target cell; the source network device forwards data to the determined target network device. In this way, by sending the first indication information to the source network device by the terminal device, the scope of data forwarding by the source network device to the target network device can be reduced, and signaling overhead can be saved.
在另一些实施例中,所述第一指示信息除了包括目标小区的编号信息,和/或目标小区的频点和PCI以外,还包括:所述目标小区的信号质量,和/或所述源小区的信号质量。In other embodiments, in addition to the number information of the target cell, and/or the frequency and PCI of the target cell, the first indication information also includes: the signal quality of the target cell, and/or the source The signal quality of the cell.
