相关申请的交叉引用
本申请主张在2017年6月23日在中国提交的中国专利申请号No.201710491042.3的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及无线通信技术领域，尤其涉及一种系统信息发送方法、接收方法、基站和移动通信终端。
背景技术
当前，无论是长期演进(LTE，Long Term Evolution)还是第五代蜂窝移动通信系统(5G NR，5th-Generation New Radio)，终端在处于无线资源控制(RRC，Radio Resource Control)空闲(Idle)状态时，都需要进行小区重选，从而保证随时可以驻留到小区，保证可以被寻呼和随时接入系统。
其中，LTE的小区重选过程主要包括以下步骤：S1，终端驻留到小区，并接收小区的系统信息，小区的系统信息中包括了小区重选信息，例如频段、带宽、偏移量等信息；S2，终端根据获取的系统信息，按照一定准则进行测量，并选择一个更合适的小区进行驻留，从而完成小区重选过程。
与LTE的系统信息相比，5G NR的系统信息在设计中，小区重选相关的信息将不再广播，而是基于终端请求的方式来告知终端。由于终端何时发起请求，并不受网络控制，因此会造成终端何时向基站请求小区重选相关的信息的不可控。

附图说明
为了更清楚地说明本公开实施例的技术方案，下面将对本公开实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本公开的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
参见图1所示，本公开实施例提供了一种系统信息发送方法，应用于基站，包括如下步骤：
步骤101：发送用于控制请求消息的发送的控制消息；
步骤102：接收移动通信终端发送的用于请求系统信息的请求消息；
步骤103：发送系统信息。
其中，系统信息可为用于移动通信终端进行小区重选的信息。移动通信终端在发送请求消息时，可驻留在小区并处于RRC连接状态。
这样，本公开实施例的系统信息发送方法，通过发送用于控制请求消息的发送的控制消息，接收移动通信终端发送的用于请求系统信息的所述请求消息，发送系统信息，能够使得基站在发送系统信息之前，发送用于控制请求消息的发送的控制消息，而移动通信终端根据接收到的控制消息，发送用于请求系统信息的请求消息，从而实现由网络控制终端何时向基站请求系统信息，实现终端请求消息的有序发送。
本公开实施例中，由于基站所持有的邻区信息很多，因此基站在将所持有的邻区信息发送给移动通信终端时，将占用较多的下行资源，特别的，若邻区信息通过专用信令采用一对一的方式进行发送，消耗的下行资源将更多。所以，为了避免消耗过多的下行资源，基站在控制移动通信终端发送请求消息时，可进一步控制移动通信终端何种条件下发送请求消息。
具体的，基站发送给移动通信终端的控制消息中可携带以下一种或者几种控制参数的门限：接收参考信号功率、接收参考信号质量和接收参考信号的信号与干扰噪声比。需要说明的是，基站发送的控制消息中所携带的控制参数的门限，不限于上述三种控制参数的门限，依具体情况，也可为其他控制参数的门限，且任一种控制参数的门限可以是一个也可以是多个，本公开实施例不对其进行限制。
而移动通信终端在接收到基站发送的控制消息后，可根据控制参数的测量值和控制消息中携带的控制参数的门限，发送请求消息。具体的，请求消息可由移动通信终端在控制参数的测量值小于或等于控制参数的门限时发送。
这样，基站控制移动通信终端在控制参数的测量值满足门限条件时再发送请求消息，能够减小移动通信终端发送请求消息的次数，从而减少基站接收请求消息的次数，减少基站发送系统信息的次数，避免消耗过多的下行资源和上行资源。
下面，以控制参数为接收参考信号质量为例，说明移动通信终端发送请求消息的过程。
例如，基站发送的控制消息中携带的接收参考信号质量的门限有n个，分别为T1、T2、T3…Tn，门限的单位是dB；移动通信终端在执行接收参考信号质量的测量操作时，得到的测量值分别为X1、X2、X3…Xn，其中n是大于或等于1的自然数。
一种发送请求消息的条件可能为：若存在“Fi(Xi)不大于或者小于Ti，其中i为1到n之间的一个自然数，Fi是一个关于测量值Xi的函数，比如Fi(Xi)＝Xi-Offset，Offset是一个移动通信终端已知的预设数值或者根据已知的预设数值计算得到的数值”，则移动通信终端向基站发送请求消息；
或者，另一种发送请求消息的条件可能为：若对于任何i，“Fi(Xi)不大于或者小于Ti，其中i为1到n之间的一个自然数，Fi是一个关于测量值Xi的函数，比如Fi(Xi)＝Xi-Offset，Offset是一个移动通信终端已知的预设数值或者根据已知的预设数值计算得到的数值”，则移动通信终端向基站发送请求消息。
应说明的是，移动通信终端在执行控制参数的测量操作时，得到的测量值的数量不一定要与控制消息中携带的对应控制参数的门限的数量相同，即可不同也可相同，而是否要相同可以依据终端需求或预先约定而定。
本公开实施例中，为了避免消耗过多的下行资源，基站除可控制移动通信终端何种条件下发送请求消息外，还可依据终端需求，有选择的下发系统信息。因此，本公开实施例的系统信息发送方法还包括：
依据筛选参数，从所有系统信息中筛选出步骤103中发送的系统信息。
其中，筛选参数可通过移动通信终端发送的请求消息携带，也可由基站根据移动通信终端的实际情况确定。
这样，基站在发送系统信息之前，有选择的从所有系统信息中筛选系统信息进行发送，能够减少系统信息的发送量，避免消耗过多的下行资源。
本公开实施例中，筛选参数可为用于指示目标频段、移动通信终端的位置和/或目标小区的参数。其中，当筛选参数为用于指示目标频段的参数时，筛选参数一般通过移动通信终端发送的请求消息携带。举例来说，当筛选参数为用于指示目标频段的参数时，筛选参数可为目标频段信息，比如B1、B2…Bj，其中j是大于或等于1自然数；或者筛选参数可为比特信息，此情况下，基站可先广播比特信息与目标频段信息的映射表，比如若目标频段信息有两个，则可用比特信息0和1映射这两个目标频段信息，以使移动通信终端根据自身需求的目标频段，确定对应的比特信息，并通过请求消息携带。
当筛选参数为用于指示移动通信终端的位置和/或目标小区的参数时，筛选参数一般由基站根据移动通信终端的实际情况确定。举例来说，当筛选参数为用于指示移动通信终端的位置或目标小区的参数时，筛选参数可为移动通信终端所处的波束信息，比如beam ID，而基站根据移动通信终端所处的波束信息可判定出移动通信终端的位置或目标小区，从而有选择的筛选系统信息进行发送。
此外，要说明的是，移动通信终端在发送用于请求系统信息的请求消息时，该请求消息中的信息可通过随机接入的消息1(message1)、消息3(message3)和消息5(message5)中的一条或者多条携带并发送。
上述实施例对本公开的基站侧的系统信息发送方法进行了说明，下面将结合实施例和附图对本公开的终端侧的系统信息接收方法进行说明。
参见图2所示，本公开实施例还提供了一种系统信息接收方法，应用于移动通信终端，包括如下步骤：
步骤201：接收基站发送的用于控制请求消息的发送的控制消息；
步骤202：发送用于请求系统信息的请求消息；
步骤203：接收基站发送的系统信息。
其中，系统信息可为用于移动通信终端进行小区重选的信息。
这样，本公开实施例的系统信息接收方法，通过接收基站发送的用于控制请求消息的发送的控制消息，发送用于请求系统信息的请求消息，接收基站发送的系统信息，能够使得基站在发送系统信息之前，发送用于控制请求消息的发送的控制消息，而移动通信终端根据接收到的控制消息，发送用于请求系统信息的请求消息，从而实现由网络控制终端何时向基站请求系统信息，实现终端请求消息的有序发送。
本公开实施例中，基站发送给移动通信终端的控制消息中可携带以下一种或者几种控制参数的门限：接收参考信号功率、接收参考信号质量和接收参考信号的信号与干扰噪声比。
进一步的，参见图3所示，在步骤201至步骤203的基础上，本公开实施例的系统信息接收方法还可包括：
步骤204：执行测量操作，得到控制参数的至少一个测量值；
步骤205：判断控制参数的测量值是否小于或等于控制参数的门限；
其中，在控制参数的测量值小于或等于控制参数的门限时，执行步骤202，否则执行步骤204。
具体的，请求消息中可携带一筛选参数，用于基站从所有系统信息中筛选出发送的系统信息。
具体的，该筛选参数为用于指示目标频段的参数。
具体的，控制消息中携带有原始参数集，本公开实施例的系统信息接收方法还可包括：
从原始参数集中选择筛选参数。
参见图4所示，本公开实施例还提供了一种系统信息发送方法，应用于基站，包括如下步骤：
步骤401：接收移动通信终端发送的用于指示目标频段的频段参数；
步骤402：发送系统信息。
其中，系统信息为用于移动通信终端进行小区重选的信息。
这样，本公开实施例的系统信息发送方法，通过接收移动通信终端发送的用于指示目标频段的频段参数，发送系统信息，能够使得基站根据移动通信终端发送的用于指示目标频段的频段参数，发送系统信息，从而实现基站 有选择的为移动通信终端发送系统信息，减少系统信息的发送量，避免消耗过多的下行资源。
具体的，本公开实施例的系统信息发送方法还可包括：
发送用于指示可选频段的通知消息；
其中，目标频段为可选频段中的一个或多个。
参见图5所示，本公开实施例还提供了一种系统信息接收方法，应用于移动通信终端，包括如下步骤：
步骤501：发送用于指示目标频段的频段参数；
步骤502：接收系统信息。
其中，系统信息为用于移动通信终端进行小区重选的信息。
这样，本公开实施例的系统信息接收方法，通过发送用于指示目标频段的频段参数，接收系统信息，能够使得基站根据移动通信终端发送的用于指示目标频段的频段参数，发送系统信息，从而实现基站有选择的为移动通信终端发送系统信息，减少系统信息的发送量，避免消耗过多的下行资源。
具体的，本公开实施例的系统信息接收方法还可包括：
接收基站发送的用于指示可选频段的通知消息；
其中，目标频段为可选频段中的一个或多个。
