具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请的各实施例进行详细的阐述。然而，本领域的普通技术人员可以理解，在本申请各实施例中，为了使读者更好地理解本申请而提出了许多技术细节。但是，即使没有这些技术细节和基于以下各实施例的种种变化和修改，也可以实现本申请所要求保护的技术方案。以下各个实施例的划分是为了描述方便，不应对本申请的具体实现方式构成任何限定，各个实施例在不矛盾的前提下可以相互结合相互引用。
在5G(5rd Generation，第五代)网络架构中，5G gNB与4G eNB在NSA进行双连接；其中，5G gNB支持的载波参数的数量最多可达16个。
然而，在NSA不支持5G gNB与UE直接进行无线信令承载时，需要由4G eNB通过X2接口负责UE和5G gNB之间的信令传输，由于5G gNB支持的载波参数的数量最多可达16个，即RRC Reconfiguration消息中最多可以包含16个载波参数，这样的话RRC Reconfiguration消息的长度很长；而4G eNB作为上一代无线基站，由于型号、硬件系统限制以及软件系统限制等原因可能造成无法支持较长长度的RRC Reconfiguration消息的处理，可能造成载波参数传输的失败。
本申请实施例的主要目的在于提出一种载波配置方法、服务器及存储介质，可以尽可能的避免出现4G基站无法传输载波参数的问题，从而实现载波参数的配置。
本申请的第一实施例涉及一种载波配置方法，应用于5G基站。具体流程如图1所示，包括：
步骤101，获取4G基站支持的载波参数的数量N1。
具体地说，若终端需要使用5G基站的载波参数进行数据传输时，终端需要先在本地配置5G基站支持的载波参数，由于5G基站需要通过4G基站与终端进行通信，在5G基站将载波参数发送至终端的过程中，发送的辅载波参数的数量会受到4G基站支持的载波参数的数量的限制，所以5G基站需要先获取4G基站支持的载波参数的数量N1。
在一个例子中，获取4G基站支持的载波参数的数量N1的具体流程图如图2所示，步骤101包括子步骤1011和子步骤1012。
子步骤1011，接收4G基站发送的基站连接请求。
子步骤1012，从基站连接请求中获取4G基站支持的载波参数的数量N1。
具体地说，终端在移动的过程中，终端与其他5G基站之间的信号可能变弱，而与当前5G基站之间的信号可能变强，此时其他5G基站通过终端测量报告可以感知信号强度的变化，从而知道需要向当前5G基站切换，其他5G基站和当前5G基站均通过当前4G基站与终端进行通信。其他5G基站先向4G基站发送包含4G基站支持的载波参数的数量N1的基站切换请求，N1为大于或等于1的整数，且基站切换请求还指示从其他5G基站切换至当前5G基站，所以4G基站接收到基站切换请求后，将包含4G基站支持的载波参数的数量N1的基站连接请求发送给当前5G基站，当前5G基站接收4G基站发送的包含4G基站支持的载波参数的数量N1基站连接请求。5G基站再对基站连接请求进行解析可以获取4G基站支持的载波参数的数量N1。
通过这样的方法，可以从4G基站直接获取到4G基站支持的载波参数的数量N1，可以较快的获取到4G基站支持的载波参数的数量。
在一个例子中，获取4G基站支持的载波参数的数量N1的具体流程图如图3所示，步骤101包括子步骤1013至子步骤1019。
子步骤1013，将包含Z个辅载波参数的配置请求发送给4G基站；其中，Z个辅载波参数从M个辅载波参数中读取，Z为大于或等于1的整数。
具体地说，5G基站从支持的M个辅载波参数中读取Z个辅载波参数，并将包含Z个辅载波参数的配置请求发送给4G基站，Z为大于或等于1的整数。在一个例子中，第一次Z的取值为M，即5G基站将包含M个辅载波参数的配置请求发送给4G基站。通过这样的方法，若4G基站支持的载波参数的数量为M时，由于是从最大的数M开始尝试的，所以可以较准确的获取4G基站支持的载波参数的数量M。
子步骤1014，在预设时长内是否接收到4G基站的回应。若是，进入子步骤1015；若否，进入子步骤1017。
子步骤1015，接收到的4G基站的回应是否为表征配置请求处理成功的消息。若是，进入子步骤1019；若否，进入子步骤1016。
子步骤1016，接收到的4G基站回应的表征配置请求处理失败的消息中是否包含4G基站支持的载波参数的数量。若是，进入子步骤1018；若否，进入子步骤1017。
子步骤1017，令本次Z的取值小于上一次Z的取值。
子步骤1018，获取4G基站支持的载波参数的数量N1。
子步骤1019，获取4G基站支持的载波参数的数量N1为本次Z。
具体地说，4G基站在接收到包含Z个辅载波参数的配置请求后，若4G基站支持的载波参数的数量小于Z，则4G基站无法对配置请求进行处理，从而无法将配置请求发送给终端，此时4G基站可以不回应5G基站，也可以向5G基站回应表征配置请求处理失败的消息。5G基站可以根据实际需要进行预设时长的设定，若5G基站在预设时长内未接收到4G基站的回应，或者接收到4G基站回应的表征配置请求处理失败的消息，则令本次Z的取值小于上一次Z的取值，并重新进入步骤1013。
若5G基站在预设时长内接收到回应，且回应的是表征配置请求处理失败的消息，5G基站对表征配置请求处理失败的消息进行解析，若表征配置请求处理失败的消息中包含4G基站支持的载波参数的数量N1，则直接获取到4G基站支持的载波参数的数量N1；若表征配置请求处理失败的消息中不包含4G基站支持的载波参数的数量，则令本次Z的取值小于上 一次Z的取值，并重新进入步骤1013。
在一个例子中，本次Z的取值为上一次Z的取值减去1，这样依次对Z进行取值，使得Z的取值的调整步长较小，可以较准确的获取4G基站支持的载波参数的数量。
在一个例子中，本次Z的取值为上一次Z的取值除以n得到的整数，n为大于或等于2的整数，通过这样的方法，可以较快的获取4G基站支持的载波参数的数量。
在一个例子中，4G基站在接收到包含Z个辅载波参数的配置请求后，若4G基站支持的载波参数的数量大于或等于Z，4G基站可以对配置请求进行处理，4G基站将包含Z个辅载波参数的配置请求发送给终端，并回应表征配置请求处理成功的消息给5G基站；5G基站在预设时长内接收到4G基站回应的表征配置请求处理成功的消息，获取4G基站支持的载波参数的数量N1为本次Z。
在一个例子中，表征配置请求处理成功的消息为4G基站回应的的Z个辅载波参数的配置成功消息。4G基站在接收到包含Z个辅载波参数的配置请求后，若4G基站支持的载波参数的数量大于或等于Z，4G基站可以对配置请求进行处理，4G基站将包含Z个辅载波参数的配置请求发送给终端，终端在接收到配置请求后配置Z个辅载波参数，并向4G基站回应Z个辅载波参数的配置成功消息，4G基站将回应的Z个辅载波参数的配置成功消息发送给5G基站，5G基站在预设时长内接收到4G基站回应的Z个辅载波参数的配置成功消息，获取4G基站支持的载波参数的数量N1为本次Z。
通过这样的方法，利用多次消息的交互，可以准确的获取4G基站支持的载波参数的数量。
在一个例子中，获取4G基站支持的载波参数的数量N1，包括：5G基站本地存储有多个4G基站的标识，由于5G基站知道与自己连接的4G基站是哪一个，所以5G基站可以从本地获取4G基站的标识。根据标识，查询5G基站本地存储的标识和载波参数的数量的对应关系，若查询到4G基站的标识对应的载波参数的数量，获取4G基站支持的载波参数的数量N1；若未查询到4G基站的标识对应的载波参数的数量，5G基站则利用多次消息的交互，获取4G基站支持的载波参数的数量。
在一个例子中，获取4G基站支持的载波参数的数量N1，包括：5G基站本地存储有多个4G基站的标识，由于5G基站知道与自己连接的4G基站是哪一个，所以5G基站可以从本地获取4G基站的标识。5G基站将包含4G基站标识的请求消息发送给外部网管设备，外部网管设备查询外部网管设备本地存储的标识和载波参数的数量的对应关系，若查询到4G基站的标识对应的载波参数的数量，获取4G基站支持的载波参数的数量N1，并将包含4G基站支持的载波参数的数量N1的消息发送给5G基站，从而使5G基站获取4G基站支持的载波参数的数量N1；若未查询到4G基站的标识对应的载波参数的数量，外部网管设备回应查询失败的消息给5G基站，5G基站则利用多次消息的交互，获取4G基站支持的载波参数的数量。其中，外部网管设备本地存储的标识和载波参数的数量的对应关系是预先通过人工设定的。通过这样的方法，可以较快的获取4G基站支持的载波参数的数量N1。
步骤102，执行配置步骤，配置步骤包括：将5G基站支持的M个辅载波参数中的若干个辅载波参数通过4G基站发送至终端；其中，若干个辅载波参数的数量不大于N1，配置步骤被执行K次，N1、M、K均为大于或等于1的整数。
具体地说，5G基站从5G基站支持的M个辅载波参数中读取若干个辅载波参数，将若干 个辅载波参数发送给4G基站，4G基站将若干个辅载波参数发送给终端，其中，若干个辅载波参数的数量不大于N1，配置步骤被执行K次，N1、M、K均为大于或等于1的整数。
在一个例子中，若干个辅载波参数包含在配置请求的消息中，即5G基站将包含若干个辅载波参数的配置请求发送给4G基站。
在一个例子中，所述方法还包括：重复执行配置步骤，直至M个辅载波参数全部通过4G基站发送至终端。通过这样的方法，可以将5G基站支持的所有的载波参数均配置到终端，使终端可使用的载波更多，可以提高数据传输性能。
在一个例子中，在每次执行配置步骤时，从M个辅载波参数中读取的若干个辅载波参数为不重复读取，即上一次执行配置步骤中已经被读取的若干个辅载波参数不再被读取。例如：在执行第一次配置步骤时，将A、B、C三个辅载波参数通过4G基站发送至终端，在执行第二次配置步骤时，不再将A或B或C中的任意一个辅载波参数发送至4G基站。通过这样的方法，可以较快的实现将5G基站支持的M个辅载波参数全部发送至终端。
在一个例子中，在每次执行配置步骤之后，5G基站在接收到终端通过4G基站回应的若干个辅载波参数配置成功的消息之后，才再次执行配置步骤。通过这样的方法，5G基站可以确认本次执行的配置步骤已经使终端将若干个辅载波参数配置成功。
在一个例子中，若干个辅载波参数的数量等于N1，通过这样的方法，可以较快的实现将5G基站支持的M个辅载波参数全部发送至终端。
在一个例子中，在执行配置步骤之前，5G基站将其支持的主载波参数通过4G基站发送给终端，终端在接收到主载波参数后进行主载波参数的配置。
在一个例子中，在执行配置步骤之前，还包括：接收其他4G基站通过当前4G基站发送的基站连接请求，从基站连接请求中获取其他4G基站支持的载波参数的数量N2；在第一次执行配置步骤时，将5G基站支持的M个辅载波参数中的若干个辅载波参数通过4G基站发送至终端；其中，若干个辅载波参数的数量不大于N1，包括：将5G基站支持的M个辅载波参数中的若干个辅载波参数依次通过当前4G基站和其他4G基站发送至终端；其中，若干个辅载波参数的数量不大于min[N1，N2]。
具体地说，终端在移动的过程中，终端与其他4G基站之间的信号可能变弱，而与当前4G基站之间的信号可能变强，此时其他4G基站通过终端测量报告可以感知信号强度的变化，从而知道需要向当前4G基站切换，所以其他4G基站向当前4G基站发送包含其他4G基站支持的载波参数的数量N2的基站连接请求，当前4G基站知道自身对应的是当前5G基站，所以当前4G基站向当前5G基站发送包含其他4G基站支持的载波参数的数量N2的基站连接请求，当前5G基站从基站连接请求中获取其他4G基站支持的载波参数的数量N2。在第一次执行配置步骤时，由于当前5G基站需要先通过当前4G基站，再通过其他4G基站与终端进行通信，所以当前5G基站发送的载波参数的数量需要同时考虑其他4G基站支持的载波参数的数量N2和当前4G基站支持的载波参数的数量N1，即若干个辅载波参数的数量不大于min[N1，N2]。通过这样的方法，在第一次执行配置步骤时，同时考虑了其他4G基站和当前4G基站支持的载波参数的数量，避免出现其他4G基站或当前4G基站无法传输载波参数的问题，从而实现载波参数的配置。
本实施例中，5G基站获取4G基站支持的载波参数的数量N1；执行配置步骤，配置步骤包括：将5G基站支持的M个辅载波参数中的若干个辅载波参数通过4G基站发送至终端； 其中，若干个辅载波参数的数量不大于N1，配置步骤被执行K次，N1、M、K均为大于或等于1的整数。由于若干个辅载波参数的数量不大于4G基站支持的载波参数的数量N1，可以尽可能地避免出现4G基站无法传输载波参数的问题，从而实现载波参数的配置。
本申请的第二实施例涉及一种载波配置方法，应用于4G基站，具体流程图如图4所示，包括：
步骤201，接收第一5G基站发送的包含4G基站支持的载波参数的数量N1的基站切换请求；其中，N1为大于或等于1的整数，基站切换请求还指示从第一5G基站切换至第二5G基站。
具体地说，终端在移动的过程中，终端与第一5G基站之间的信号可能变弱，而与第二5G基站之间的信号可能变强，此时第一5G基站通过终端测量报告可以感知信号强度的变化，从而知道需要向第二5G基站切换，其他5G基站和当前5G基站均通过当前4G基站与终端进行通信。第一5G基站向4G基站发送包含4G基站支持的载波参数的数量N1的基站切换请求，N1为大于或等于1的整数，且基站切换请求还指示从第一5G基站切换至第二5G基站，这样4G基站在接收到基站切换请求后，4G基站可以知道其自身支持的载波参数的数量N1，且可以知道第一5G基站要切换至第二5G基站。
步骤202，向第二5G基站发送包含4G基站支持的载波参数的数量N1的基站连接请求。
步骤203，接收第二5G基站发送的包含P个载波参数的配置请求，并将P个载波参数中的若干个载波参数发送至终端；其中，P个载波参数中至少包括辅载波参数，P不大于N1，N1、P为大于或等于1的整数。
具体地说，4G基站向第二5G基站发送包含4G基站支持的载波参数的数量N1的基站连接请求，第二5G基站接收到基站连接请求之后可以知道4G基站支持的载波参数的数量N1，并从第二5G基站自身支持的M个载波参数中读取P个载波参数，P个载波参数中至少包括辅载波参数，并将包含第二5G基站的P个载波参数的配置请求发送给4G基站，P不大于N1，P为大于或等于1的整数。
4G基站在接收到第二5G基站发送的P个载波参数的配置请求后，向终端发送包含若干个载波参数的配置请求，终端接收到配置请求后，解析配置请求得到若干个载波参数，并进行若干个载波参数的配置；此时，第一5G基站成功切换至第二5G基站。
在一个例子中，终端成功配置若干个载波参数之后，还会向4G基站回应若干个载波参数配置成功的消息，4G基站接收到配置成功的消息之后，4G基站向第一5G基站发送基站切换成功的消息以及内容释放的消息，通知第一5G基站已经成功进行基站切换，使第一5G基站进行终端内容的释放。
在一个例子中，4G基站接收到回应的若干个载波参数的配置成功的消息之后，向第二5G基站回应若干个载波参数的配置成功的消息。
在一个例子中，方法还包括：执行配置步骤，配置步骤包括：将第二5G基站支持的剩余的个载波参数中的若干个载波参数通过4G基站发送至终端；其中，若干个载波参数的数量不大于N1，配置步骤被执行K次，N1、M、K均为大于或等于1的整数。在一个例子中，重复执行配置步骤，直至M个载波参数全部通过4G基站发送至终端。在一个例子中，第二5G基站在接收到终端通过4G基站回应的配置成功的消息之后，才再次执行配置步骤。
本实施例中，在第一5G基站切换至第二5G基站的过程中，同时携带P个载波参数，这 样可以使终端较快的获得载波参数，从而较快的进行载波参数的配置。
本申请的第三实施例涉及一种载波配置方法，应用于第一4G基站，具体流程图如图5所示，包括：
步骤301，通过第二4G基站向第二5G基站发送包含第一4G基站支持的载波参数的数量N2基站连接请求。
具体地说，终端在移动的过程中，终端与第一4G基站之间的信号可能变弱，而与第二4G基站之间的信号可能变强，此时第一4G基站通过终端测量报告可以感知信号强度的变化，从而知道需要向第二4G基站切换，所以第一4G基站向第二4G基站发送包含第一4G基站支持的载波参数的数量N2的基站连接请求，第二4G基站知道自身对应的是第二5G基站，所以第二4G基站向第二5G基站发送包含第一4G基站支持的载波参数的数量N2的基站连接请求。
在一个例子中，在步骤301之前，还包括：第一4G基站向第一5G基站发送基站切换请求，第一5G基站在接收到基站切换请求后，向第一4G基站发送包含第一4G基站支持的载波参数的数量N2的同意基站切换的应答。
步骤302，通过第二4G基站接收第二5G基站发送的包含L个载波参数的配置请求，并将L个载波参数中的若干个载波参数发送至终端；其中，L个载波参数中至少包括辅载波参数，L不大于N1，L为大于或等于1的整数。
在一个例子中，先获取第二4G基站支持的载波参数的数量N2，包括：第二5G基站向第二4G基站发送包含L个载波参数的配置请求，L不大于N2，L个载波参数中至少包括辅载波参数，若接收到第二4G基站回应的表征配置请求处理失败的消息，且消息中包含第二4G基站支持的载波参数的数量N1，获取第二4G基站支持的载波参数的数量N1；第二5G基站再向第二4G基站发送包含L个载波参数的配置请求，此时L不大于min[N1，N2]，第二4G基站将包含L个载波参数的配置请求发送给第一4G基站，此时，第一4G基站成功切换至第二4G基站，第一5G基站成功切换至第二5G基站。第一4G基站向终端发送包含L个载波参数的配置请求，终端接收到配置请求后，解析配置请求得到L个载波参数，并进行L个载波参数的配置。
第二5G基站向第二4G基站发送包含L个载波参数的配置请求，L不大于N2，若接收到第二4G基站回应的表征配置请求处理失败的消息，且消息中不包含第二4G基站支持的载波参数的数量，或者，若在预设时长内未接收到第二4G基站的回应，令本次L的取值小于上一次L的取值，重复执行获取第二4G基站支持的载波参数的数量N1，直至第二5G基站获取到第二4G基站回应的表征配置请求处理成功的消息。在一个例子中，第二4G基站回应表征配置请求处理成功的消息给第二5G基站的同时，将包含本次L个载波参数的配置请求发送给第一4G基站，此时，第一4G基站成功切换至第二4G基站，第一5G基站成功切换至第二5G基站。第一4G基站向终端包含本次L个载波参数的配置请求，终端接收到配置请求后，解析配置请求得到L个载波参数，并进行L个载波参数的配置。在一个例子中，表征配置请求处理成功的消息为第二4G基站回应的L个载波参数的配置成功消息。第二4G基站在接收到包含本次L个载波参数的配置请求后，若第二4G基站支持的载波参数的数量大于或等于L，第二4G基站可以对配置请求进行处理，则第二4G基站将包含L个载波参数的配置请求发送给第一4G基站，此时，第一4G基站成功切换至第二4G基站，第一5G基站成 功切换至第二5G基站。第一4G基站将包含L个载波参数的配置请求发送给终端，终端在接收到配置请求后配置L个载波参数，并向第二4G基站回应L个载波参数的配置成功消息，第二4G基站将回应的L个载波参数的配置成功消息发送给5G基站，5G基站在预设时长内接收到第二4G基站回应的L个辅载波参数的配置成功消息，获取第二4G基站支持的载波参数的数量N1为本次L。
在一个例子中，L不大于min[N1，N2]，N1为第二5G基站预先存储的第二4G基站支持的载波参数的数量。第二5G基站知道自身对应的是第二4G基站，从本地获取第二4G基站的标识，并查询第二5G基站本地存储的标识和载波参数的数量的对应关系，获取到第二4G基站支持的载波参数的数量N1。由于在基站切换的过程中，第二5G基站需要先通过第二4G基站，再通过第一4G基站与终端进行通信，所以第二5G基站发送的载波参数的数量需要同时考虑第一4G基站支持的载波参数的数量N2和第二4G基站支持的载波参数的数量N1，所以L不大于min[N1，N2]，L个载波参数中至少包括辅载波参数，即，第二5G基站向第二4G基站发送的包含L个载波参数的配置请求；其中，L不大于min[N1，N2]，第二4G基站将包含L个载波参数的配置请求发送给第一4G基站，此时，第一4G基站成功切换至第二4G基站，第一5G基站成功切换至第二5G基站。第一4G基站向终端发送包含L个载波参数的配置请求，终端接收到配置请求后，解析配置请求得到L个载波参数，并进行L个载波参数的配置。通过这样的方法，在第一5G基站切换至第二5G基站以及第一4G基站切换至第二4G基站的过程中，当第二5G基站预先存储的所述第二4G基站支持的载波参数的数量时，同时兼顾了第一4G基站和第二4G基站支持的载波参数的数量，实现载波参数的配置。
在一个例子中，在第一4G基站接收到包含L个载波参数的配置请求之后，方法还包括：第一4G基站向第一5G基站发送基站释放请求，第一5G基站回应第一4G基站同意基站释放的消息。
在一个例子中，终端成功配置L个载波参数之后，还会向第二4G基站回应L个载波参数配置成功的消息，第二4G基站接收到配置成功的消息之后，第二4G基站向第二5G基站发送配置成功的消息。
在一个例子中，终端成功配置L个载波参数之后，第二4G基站向第一4G基站发送内容释放的消息，第一4G基站将内容释放的消息发送给第一5G基站，使第一5G基站进行终端内容的释放。
在一个例子中，方法还包括：执行配置步骤，配置步骤包括：将第二5G基站支持的剩余的载波参数中的若干个载波参数通过第二4G基站发送至终端；其中，若干个载波参数的数量不大于N1，配置步骤被执行K次，N1、M、K均为大于或等于1的整数。在一个例子中，重复执行配置步骤，直至M个辅载波参数全部通过第二4G基站发送至终端。在一个例子中，第二5G基站在接收到终端通过第二4G基站回应的配置成功的消息之后，才再次执行配置步骤。
本实施例中，在第一5G基站切换至第二5G基站以及第一4G基站切换至第二4G基站的过程中，同时携带L个载波参数，这样可以使终端较快的获得载波参数，从而较快的进行载波参数的配置。
