Detailed ways

为了能够更加详尽地了解本发明实施例的特点与技术内容，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。The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

实施例一、Embodiment 1

本发明实施例提供了一种切换处理方法，应用于第一网络设备，如图1所示，包括：An embodiment of the present invention provides a handover processing method, which is applied to a first network device, as shown in FIG. 1 , and includes:

步骤101：当目标终端需要切换至第二网络设备时，获取所述目标终端的目标承载使用的PDCP第一版本；Step 101: Obtain a first version of the PDCP used by the target bearer of the target terminal when the target terminal needs to switch to the second network device.

步骤102：基于所述目标终端的目标承载使用的PDCP第一版本生成第一信息，发送所述第一信息至所述第二网络设备；Step 102: Generate first information based on the first version of the PDCP used by the target bearer of the target terminal, and send the first information to the second network device.

步骤103：接收所述第二网络设备发来的第二信息，基于所述第二信息对所述目标终端进行切换处理。Step 103: Receive second information sent by the second network device, and perform handover processing on the target terminal based on the second information.

这里，所述第一网络设备，可以为目标终端当前连接的基站，也就是为所述目标终端提供服务的原基站；第二网络设备，可以为所述目标终端所要切换至的基站，即所述目标终端发生切换时，选择的目标基站。Here, the first network device may be a base station to which the target terminal is currently connected, that is, The original base station serving the target terminal; the second network device may be the base station to which the target terminal is to be handed over, that is, the target base station selected when the target terminal is switched.

进一步地，所述第一网络设备与第二网络设备不同，且所述第一网络设备与所述第二网络设备分别属于不同的RAT。比如，两个网络设备，也就是两个基站，可以分别属于LTE和NR。Further, the first network device is different from the second network device, and the first network device and the second network device respectively belong to different RATs. For example, two network devices, that is, two base stations, may belong to LTE and NR, respectively.

前述步骤101中，所述目标终端的目标承载可以为目标终端当前使用的承载；PDCP版本可以包括有LTE PDCP版本，或者，可以包括有NR PDCP版本等等。In the foregoing step 101, the target bearer of the target terminal may be a bearer currently used by the target terminal; the PDCP version may include an LTE PDCP version, or may include an NR PDCP version or the like.

前述步骤102中，生成第一信息中，所述第一信息可以包括有：所述目标终端的目标承载所对应的PDCP第一版本的指示信息。In the foregoing step 102, the first information may be generated, where the first information may include: indication information of the first version of the PDCP corresponding to the target bearer of the target terminal.

也就是说，第一网络设备向第二网络设备(也就是目标终端的目标基站)首先发送所述目标终端的当前承载所使用的版本，其中，可以包括有目标终端的标识信息、以及PDCP版本的标识信息。当然还可以包括有其他的信息，只是这里不再进行赘述。That is, the first network device first sends the version used by the current bearer of the target terminal to the second network device (that is, the target base station of the target terminal), where the identifier information of the target terminal and the PDCP version may be included. Identification information. Of course, other information can be included, but it will not be repeated here.

需要理解的是，前述步骤102完成之后，第二网络设备能够根据接收到的第一信息进行相应的处理；比如，可以包括：从第一信息中提取目标终端的目标承载所使用的PDCP版本为PDCP第一版本；It is to be understood that after the foregoing step 102 is completed, the second network device can perform corresponding processing according to the received first information. For example, the method may include: extracting, from the first information, a PDCP version used by the target bearer of the target terminal. The first version of PDCP;

然后基于自身能力，判断是否支持所述PDCP第一版本，得到判断结果。Then, based on its own capabilities, it is determined whether the first version of the PDCP is supported, and the judgment result is obtained.

进一步地，当第二网络设备判断得到判断结果之后，可以存在多种处理方式：Further, after the second network device determines that the judgment result is obtained, there may be multiple processing manners:

方式一、当判断结果表征所述第二网络设备支持PDCP第一版本时，可以将指示所述目标终端使用PDCP第一版本的信息作为第二信息发送给第一网络设备。所述第二信息中包括：所述第二网络设备支持所述PDCP第一版本的指示信息。 Manner 1: When the judgment result indicates that the second network device supports the first version of the PDCP, the information indicating that the target terminal uses the first version of the PDCP may be sent to the first network device as the second information. The second information includes: the second network device supports the indication information of the first version of the PDCP.

方式二、当判断结果表征所述第二网络设备不支持PDCP第一版本时，可以将所述第二网络设备不支持所述PDCP第一版本的信息、以及所述第二网络设备指示所述目标终端需要使用PDCP目标版本的信息作为第二信息。也就是说，第二信息包括所述第二网络设备不支持所述PDCP第一版本的信息、以及所述第二网络设备指示所述目标终端需要使用PDCP目标版本的信息。Manner 2: When the judgment result indicates that the second network device does not support the first version of the PDCP, the second network device may not support the information of the first version of the PDCP, and the second network device indicates the The target terminal needs to use the information of the PDCP target version as the second information. That is, the second information includes information that the second network device does not support the first version of the PDCP, and information that the second network device indicates that the target terminal needs to use the PDCP target version.

方式三、不论判断结果为支持还是不支持，第二网络设备可以仅将允许目标终端使用的PDCP版本发送给目标终端，也就是说，可以将所述第二网络设备指示所述目标终端使用的PDCP目标版本作为第二信息发送给第一网络设备。此时，第二信息中包括所述第二网络设备指示所述目标终端使用的PDCP目标版本。In a third mode, the second network device may only send the PDCP version that is allowed to be used by the target terminal to the target terminal, that is, the second network device may be used to indicate the target terminal. The PDCP target version is sent as the second information to the first network device. At this time, the second information includes the PDCP target version used by the second network device to indicate the target terminal.

具体来说，当第二网络设备支持PDCP第一版本时，那么第二信息中的PDCP目标版本可以为PDCP第一版本；当第二网络设备部支持PDCP第一版本时，那么第二信息中的PDCP目标版本可以为PDCP第二版本。Specifically, when the second network device supports the first version of the PDCP, the PDCP target version in the second information may be the first version of the PDCP; when the second network device part supports the first version of the PDCP, then in the second information The PDCP target version can be the second version of PDCP.

前述步骤103中，基于所述第二信息对所述目标终端进行切换处理，具体可以为将所述第二信息发送至目标终端，以使得目标终端能够基于第二信息确定是否变换PDCP版本。In the foregoing step 103, performing handover processing on the target terminal based on the second information, specifically, sending the second information to the target terminal, so that the target terminal can determine whether to convert the PDCP version based on the second information.

综上，本实施例提供的方案，能够在目标终端的切换过程中，由目标中的原网络节点(也就是第一网络设备)向目标节点(也就是第二网络设备)发送信息，该信息指示当前承载所用的PDCP版本，比如，可以为PDCP第一版本；In summary, the solution provided in this embodiment can send information to the target node (that is, the second network device) by the original network node (that is, the first network device) in the target during the handover process of the target terminal. Indicates the version of the PDCP used by the current bearer, for example, the first version of the PDCP;

当目标基站收到该消息后，确认目标基站可以使用同样版本的PDCP实体服务当前承载，则优先使用当前版本的PDCP实体，如不能使用(例如目标基站不支持该版本的PDCP实体)，则通过第一网络设备发送其支持的PDCP目标版本，以使得所述目标终端切换PDCP实体。 After receiving the message, the target base station confirms that the target base station can use the same version of the PDCP entity to serve the current bearer, and then preferentially uses the current version of the PDCP entity. If the target base station does not support the PDCP entity, the target base station does not support the version. The first network device transmits its supported PDCP target version to cause the target terminal to switch PDCP entities.

可见，通过采用上述方案，当目标终端需要进行切换的时候，由目标终端对应的第一网络设备发送目标终端的目标承载的PDCP版本至第二网络设备，进而根据第二网络设备发来的第二信息对目标终端进行切换处理。如此，就能够使得第二网络设备在切换处理时，获知目标终端的PDCP版本，从而保证第二网络设备在确定第二信息的时候，优选目标终端当前使用的PDCP版本，这样就能够减少目标终端进行切换时由于进行PDCP版本重配置而产生的承载中断、以及丢包等问题。It can be seen that, by using the foregoing solution, when the target terminal needs to perform the handover, the first network device corresponding to the target terminal sends the PDCP version of the target bearer of the target terminal to the second network device, and then sends the second network device according to the second network device. The second information is switched to the target terminal. In this way, the second network device can obtain the PDCP version of the target terminal during the handover process, thereby ensuring that the second network device optimizes the PDCP version currently used by the target terminal when determining the second information, so that the target terminal can be reduced. Issues such as bearer interruption and packet loss due to PDCP version reconfiguration during handover.

实施例二、Embodiment 2

本发明实施例提供了一种切换处理方法，应用于第二网络设备，如图2所示，包括：The embodiment of the present invention provides a handover processing method, which is applied to a second network device, as shown in FIG. 2, and includes:

步骤201：接收第一网络设备发来的第一信息，其中，所述第一信息中至少包括有所述目标终端的目标承载所对应的PDCP第一版本的指示信息；Step 201: Receive first information sent by the first network device, where the first information includes at least indication information of a first version of the PDCP corresponding to the target bearer of the target terminal.

步骤202：基于所述第一信息，生成针对所述目标终端的第二信息；Step 202: Generate second information for the target terminal based on the first information.

步骤203：发送所述第二信息至所述第一网络设备。Step 203: Send the second information to the first network device.

这里，所述第一网络设备，可以为目标终端当前连接的基站，也就是为所述目标终端提供服务的原基站；第二网络设备，可以为所述目标终端所要切换至的基站，即所述目标终端发生切换时，选择的目标基站。Here, the first network device may be a base station to which the target terminal is currently connected, that is, an original base station serving the target terminal; and the second network device may be a base station to which the target terminal is to be switched, that is, The target base station selected when the target terminal switches.

PDCP版本可以包括有LTE PDCP版本，或者，可以包括有NR PDCP版本等等。所述PDCP第一版本可以为LTE PDCP也可以为NR PDCP。The PDCP version may include an LTE PDCP version, or may include an NR PDCP version or the like. The first version of the PDCP may be an LTE PDCP or an NR PDCP.

第一网络设备向第二网络设备(也就是目标终端的目标基站)首先发送所述目标终端的当前承载所使用的版本，其中，第一信息中可以包括有目标终端的标识信息、以及PDCP版本的标识信息。当然还可以包括有其他的信息，只是这里不再进行赘述。The first network device first sends the version used by the current bearer of the target terminal to the second network device (that is, the target base station of the target terminal), where the first information may include the identifier information of the target terminal and the PDCP version. Identification information. Of course, it can also include His information is only to be repeated here.

需要理解的是，第二网络设备能够根据接收到的第一信息进行相应的处理；比如，基于所述第一信息，生成针对所述目标终端的第二信息可以包括以下多种处理方式：It is to be understood that the second network device can perform corresponding processing according to the received first information; for example, generating the second information for the target terminal based on the first information may include the following multiple processing manners:

处理方式一、生成指示所述目标终端使用的PDCP目标版本的第二信息。The processing manner is as follows: generating second information indicating a PDCP target version used by the target terminal.

也就是说，根据PDCP第一版本，确定自身是否支持，若支持，则将PDCP第一版本作为目标版本作为第二信息发送给第一网络设备；若不支持，可以将PDCP第二版本作为目标版本，然后将PDCP目标版本添加到第二信息中发送给第一网络设备。In other words, according to the first version of the PDCP, it is determined whether the support is supported by the first version of the PDCP. If the support is not supported, the second version of the PDCP is transmitted as the second information to the first network device. The version is then added to the second information by adding the PDCP target version to the first network device.

处理方式二、判断是否支持所述PDCP第一版本，得到判断结果；The second mode is to determine whether the first version of the PDCP is supported, and the judgment result is obtained.

与处理方式一不同之处在于，当第二网络设备支持PDCP第一版本的时候，可以选择向第一网络设备仅发送一个指示信息，该指示信息可以仅指示允许目标终端保持PDCP第一版本不变；只有当第二网络设备不支持PDCP第一版本的时候，才需要向第一网络设备发送PDCP目标版本，此时，PDCP目标版本必然与第一版本不同，可以为PDCP第二版本。The difference from the processing mode is that when the second network device supports the first version of the PDCP, the first network device may be selected to send only one indication information, and the indication information may only indicate that the target terminal is allowed to keep the first version of the PDCP. The PDCP target version needs to be sent to the first network device only when the second network device does not support the first version of the PDCP. In this case, the PDCP target version must be different from the first version and can be the second version of the PDCP.

当目标基站收到该消息后，确认目标基站可以使用同样版本的PDCP 实体服务当前承载，则优先使用当前版本的PDCP实体，如不能使用(例如目标基站不支持该版本的PDCP实体)，则通过第一网络设备发送其支持的PDCP目标版本，以使得所述目标终端切换PDCP实体。After receiving the message, the target base station confirms that the target base station can use the same version of PDCP. If the physical service is currently carried, the current version of the PDCP entity is preferentially used. If the target entity does not support the PDCP entity, the PDCP target version supported by the first network device is sent to the target terminal. Switch the PDCP entity.

第一处理单元31，当目标终端需要切换至第二网络设备时，获取所述目标终端的目标承载使用的PDCP第一版本；基于所述目标终端的目标承载使用的PDCP第一版本生成第一信息；以及基于所述第二信息对所述目标终端进行切换处理；The first processing unit 31 is configured to acquire a first version of the PDCP used by the target bearer of the target terminal when the target terminal needs to switch to the second network device, and generate the first version of the first version of the PDCP used by the target bearer of the target terminal.

所述第一信息可以包括有：所述目标终端的目标承载所对应的PDCP第一版本的指示信息。The first information may include: indication information of the first version of the PDCP corresponding to the target bearer of the target terminal.

需要理解的是，第二网络设备能够根据接收到的第一信息进行相应的处理；比如，可以包括：从第一信息中提取目标终端的目标承载所使用的PDCP版本为PDCP第一版本；It is to be understood that the second network device can perform the corresponding processing according to the received first information. For example, the method may include: extracting, from the first information, the PDCP version used by the target bearer of the target terminal as the first version of the PDCP;

方式一、当判断结果表征所述第二网络设备支持PDCP第一版本时，可以将指示所述目标终端使用PDCP第一版本的信息作为第二信息发送给第一网络设备。所述第二信息中包括：所述第二网络设备支持所述PDCP第一版本的指示信息。Manner 1: When the judgment result indicates that the second network device supports the first version of the PDCP, the information indicating that the target terminal uses the first version of the PDCP may be sent to the first network device as the second information. The second information includes: the second network device supports the indication information of the first version of the PDCP.

方式三、不论判断结果为支持还是不支持，第二网络设备可以仅将允许目标终端使用的PDCP版本发送给目标终端，也就是说，可以将所述第二网络设备指示所述目标终端使用的PDCP目标版本作为第二信息发送给第一网络设备。此时，第二信息中包括所述第二网络设备指示所述目标终端使用的PDCP目标版本。Method 3: Regardless of whether the judgment result is supported or not, the second network device may only allow The PDCP version used by the target terminal is sent to the target terminal, that is, the PDCP target version used by the second network device to be used by the target terminal may be sent to the first network device as the second information. At this time, the second information includes the PDCP target version used by the second network device to indicate the target terminal.

当目标基站收到该消息后，确认目标基站可以使用同样版本的PDCP实体服务当前承载，则优先使用当前版本的PDCP实体，如不能使用(例如目标基站不支持该版本的PDCP实体)，则通过第一网络设备发送其支持的PDCP目标版本，以使得所述目标终端切换PDCP实体。After receiving the message, the target base station confirms that the target base station can use the same version of the PDCP entity to serve the current bearer, and then preferentially uses the current version of the PDCP entity. If the target base station does not support the PDCP entity, the target base station does not support the version. The first network device transmits its supported PDCP target version to cause the target terminal to switch PDCP entities.

可见，通过采用上述方案，当目标终端需要进行切换的时候，由目标终端对应的第一网络设备发送目标终端的目标承载的PDCP版本至第二网络设备，进而根据第二网络设备发来的第二信息对目标终端进行切换处理。如此，就能够使得第二网络设备在切换处理时，获知目标终端的PDCP版本，从而保证第二网络设备在确定第二信息的时候，优选目标终端当前使用的PDCP版本，这样就能够减少目标终端进行切换时由于进行PDCP版本重配置而产生的承载中断、以及丢包等问题。 It can be seen that, by using the foregoing solution, when the target terminal needs to perform the handover, the first network device corresponding to the target terminal sends the PDCP version of the target bearer of the target terminal to the second network device, and then sends the second network device according to the second network device. The second information is switched to the target terminal. In this way, the second network device can obtain the PDCP version of the target terminal during the handover process, thereby ensuring that the second network device optimizes the PDCP version currently used by the target terminal when determining the second information, so that the target terminal can be reduced. Issues such as bearer interruption and packet loss due to PDCP version reconfiguration during handover.
