还应当进一步理解，在本申请说明书和所附权利要求书中使用的术语“和/或”是指相关联列出的项中的一个或多个的任何组合以及所有可能组合，并且包括这些组合。
本公开提供了一种网络切片接入方法、设备、系统及存储介质。下面结合附图，对本公开一些实施方式作详细说明。在不冲突的情况下，下述实施例及实施例中的特征可以相互组合。
请参阅图1，图1是本公开实施例提供的一种网络切片接入方法的示意流程图。该方法可以应用于终端设备，例如，终端设备可以是用户的手机。如图1所示，该网络切片接入方法包括如下步骤S101至步骤S103。
S101、确定已接入通信地址，该已接入通信地址包括已接入的网络切片所对应的通信地址。
网络设备中预先配置了多个网络切片，不同的网络切片对应不同的业务功能，终端设备可以根据需求接入网络设备中的网络切片。根据第三代合作伙伴计划(3GPP,3rd Generation Partnership Project)的定义，一个终端设备可以同时接入八个网络切片。网络设备可以是基站，网络切片可以是由运营商进行配置的，还可以是由第三方公司进行配置的。
不同的网络切片有各自对应的通信地址，例如，通信地址可以是互联网协议(IP,Internet Protocol Address)地址。终端设备可以向网络设备发送切片接入请求，网络设备将需要接入的网络切片的通信地址返回给终端设备，终端设备便可以根据接收到的通信地址接入对应的网络切片。
终端设备可以在先接入了若干个网络切片，后续如果用户有其他的业务功能需求，可以接入新的网络切片。可以确定终端设备当前已接入的网络切片，并获取每个网络切片对应的通信地址，确定为已接入通信地址。
S102、将切片接入请求以及已接入通信地址发送至网络设备，以使网络设备根据切片接入请求确定目标网络切片，并根据已接入通信地址为目标网络切片确定目标通信地址，目标通信地址和已接入通信地址不相同。
切片接入请求为用于向网络设备申请接入新的网络切片的请求信令，切片接入请求所对应的网络切片可以根据用户的实际需求进行设置，在此不作限定。
同时将切片接入请求和确定的已接入通信地址发送至网络设备，网络设备根据切片接入请求可以确定终端设备需要接入新的网络切片，进而可以根据切片接入请求确定对应的目标网络切片。
网络设备可以对确定的目标网络切片分配通信地址，如果网络设备随机给目标网络切片分配通信地址，很可能会出现给不同的网络切片配置了相同的通信地址的情况，而终端设备如果在先已经接入了一个通信地址的网络切片，对于后一个具有相同的通信地址的网络切片终端设备将无法接入。
因此，通过将已接入通信地址发送至网络设备，以便网络设备可以确定终端设备已经接入的网络切片以及已经在使用的通信地址，网络设备在给目标网络切片配置通信地址时，可以避免将已经使用的通信地址再次分配，可以选择和已接入通信地址中的通信地址均不相同的通信地址作为目标网络切片的目标通信地址。
S103、接收网络设备返回的目标通信地址，根据目标通信地址接入目标网络切片。
网络设备在确定了目标网络切片和目标通信地址后，可以将分配结果发送至终端设备，分配结果中可以包括是否分配成功的结果以及目标通信地址。
终端设备可以根据网络设备返回的分配结果确定是否分配成功，并根据接收的目标通信地址接入到对应的目标网络切片，完成新的网络切片的接入。
在一个实施例中，上述根据目标通信地址接入目标网络切片的操作可以通过如下方式实施：若目标通信地址和已接入通信地址不相同，则根据目标通信地址接入目标网络切片。
在接收到网络设备返回的目标通信地址时，可以进一步判断目标通信地址和已接入通信地址中包括的已接入的网络切片所对应的通信地址是否相同，在目标通信地址和已接入通信地址中包括的已接入的网络切片所对应的通信地址均不相同时，再根据目标通信地址接入目标网络切片，避免接收到的目标通信地址和已接入通信地址中包括的已接入的网络切片所对应的通信地址相同，而发生通信地址冲突的问题。
如果目标通信地址和已接入通信地址中包括的已接入的网络切片所对应的通信地址相同，可以返回执行确定已接入通信地址以及将切片接入请求以及已接入通信地址发送至网络设备的操作，重新再次申请。
在一个实施例中，上述方法还包括如下操作：将目标通信地址添加至已接入通信地址。
可以是在根据目标通信地址接入目标网络切片之后，将目标通信地址添加至已接入通信地址。在根据目标通信地址接入目标网络切片后，表示该目标网络切片已经是终端设备当前所接入的网络切片之一，因此可以将目标通信地址添加到已接入通信地址中。
本公开实施例提供的方法中，通过确定终端设备已经接入的网络切片的通信地址，并发送至网络设备，以使网络设备可以确定终端设备中已经使用的通信地址给新接入的网络切片，避免新接入的网络切片和已接入的网络切片的通信地址发生冲突，提高终端设备接入网络切片的效率。
在一个实施例中，上述方法还包括如下操作：在检测到切片释放事件时，确定切片释放事件对应的网络切片的通信地址，将切片释放事件对应的网络切片的通信地址从已接入通信地址中移除。
终端设备如果不再需要使用某个业务功能，可以取消接入对应的网络切片，终端设备可以向网络设备发送进行切片释放申请；网络设备也可以主动取消终端设备接入某个网络切片。可以是在检测终端设备向网络设备发送进行切片释放申请，或者检测到网络设备主动取消终端设备和一个网络设备的连接时，确定检测到切片释放事件。如果终端设备不再接入到一个网络切片，可以将该网络切片对应的通信地址从已接入通信地址中移除。
请参阅图2，图2是本公开实施例提供的另一种网络切片接入方法的示意流程图，该方法可以应用于网络设备，例如，网络设备可以是基站。如图2所示，该网络切片接入方法包括如下步骤S201至步骤S203。
S201、接收终端设备发送的切片接入请求和已接入通信地址，该已接入通信地址包括终端设备已接入的网络切片所对应的通信地址。
终端设备可以确定当前已接入的网络切片，并获取每个网络切片对应的通信地址，确定为已接入通信地址。终端设备在需要接入新的网络切片时，可以发送切片接入请求和已接入通信地址至网络设备。
S202、根据切片接入请求确定目标网络切片，以及根据已接入通信地址为目标网络切片确定目标通信地址，目标通信地址和已接入通信地址不相同。
切片接入请求为用于向网络设备申请接入新的网络切片的请求信令，切片接入请求所对应的网络切片可以根据用户的实际需求进行设置，网络设备可以根据接收的切片接入请求确定目标网络切片，作为终端设备新接入的网络切片。
网络设备可以根据已接入通信地址确定终端设备中已经接入的网络切片以及已经在使用的通信地址，网络设备根据已接入通信地址为目标网络切片确定目标通信地址，可以避免将已经使用的通信地址再次分配。
S203、将目标通信地址发送至终端设备。
网络设备在确定目标网络切片以及目标通信地址后，可以将目标通信地址发送给终端 设备，以便终端设备可以根据目标通信地址接入目标网络切片。网络设备可以是发送分配结果至终端设备，分配结果中可以包括是否分配成功的结果以及目标通信地址。
在一个实施例中，上述根据已接入通信地址为目标网络切片确定目标通信地址的操作可以通过下方式实施：确定与已接入通信地址不相同的第一通信地址，将第一通信地址确定为目标网络切片的目标通信地址。
网络设备选择一个与已接入通信地址中包括的已接入的网络切片所对应的通信地址均不相同的通信地址作为目标通信地址，以便终端设备可以根据目标通信地址顺利接入目标网络切片，避免出现地址冲突而无法接入的问题。
本公开实施例提供的方法中，通过确定终端设备已经接入的网络切片的通信地址，并发送至网络设备，以使网络设备可以确定终端设备中已经使用的通信地址给新接入的网络切片，避免新接入的网络切片和已接入的网络切片的通信地址发生冲突，提高终端设备接入网络切片的效率。
