Description

系统信息变更通知方法、装置及计算机可读存储介质 技术领域
本公开涉及通信技术领域，尤其涉及一种系统信息变更通知方法、装置及计算机可读存储介质。
背景技术
终端在接入基站时，需要获取基站广播的系统信息，以根据该系统信息准确接入基站来进行通信。系统信息分为MIB(Master Information Block，主信息块)和多个SIB(System Information Block，系统信息块)，不同的信息块承载着不同类型的系统信息。由于终端只有在获取到正确的系统信息时才能接入基站，因此，当基站广播的系统信息需要发生变更时，基站需要通知终端系统信息需要发生变更，以便终端在得到通知后可以更新系统信息。
目前，基站通知终端系统信息需要发生变更的方式有两种。一种是基站在发送给终端的寻呼信息中增加systemInfoModification(系统信息修改)字段，此时如果终端接收到该寻呼信息，则可以确定除SIB10、11、12、14之外的系统信息中有系统信息需要发生变更。另一种是基站修改所广播的SIB1中的systemInfoValueTag(系统信息值标签)字段，此时如果终端接收到该SIB1，则可以确定除MIB和SIB1、10、11、12、14之外的系统信息中有系统信息需要发生变更。

附图说明
此处的附图被并入说明书中并构成本说明书的一部分，示出了符合本发明的实施例，并与说明书一起用于解释本发明的原理。
图1是根据一示例性实施例示出的一种实施环境的示意图。
图2是根据一示例性实施例示出的第一种系统信息变更通知方法的流程图。

图8是根据一示例性实施例示出的第四种系统信息变更通知装置的框图。
具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描 述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
首先，对本公开实施例涉及的名词进行说明。
系统信息：基站在BCCH(Broadcast Control Channel，广播控制信道)上进行周期性广播的信息，用于实时告知终端网络的具体情况，按照类型可以分为MIB和多个SIB。
bitmap(位图)：将多个位(bit)与多个信息一一对应，并用各个位上的值指示各个位对应的信息的状态。
加扰：一种数字信号的加工处理方式，使用扰码将原始数字信号扰乱成新的数字信号的过程。
解扰：加扰的逆过程，使用扰码将加扰的数字信号恢复成原始数字信号的过程。
其次，对本公开实施例涉及的应用场景进行说明。
当基站广播的系统信息需要发生变更时，基站会通知终端系统信息需要发生变更，以便终端在得到通知后可以更新系统信息，进而基于更新后的系统信息准确接入基站。目前，基站通知终端系统信息需要发生变更时，一般通过在发送给终端的寻呼信息中增加systemInfoModification字段，或者通过修改所广播的SIB1中的systemInfoValueTag字段这两种方式来实现。这两种方式只能告知终端某些系统信息中有系统信息需要发生变更，所以终端在得到通知后需要对这些系统信息都进行更新。然而，终端对这些系统信息中不需要发生变更的系统信息的更新实际上是没有必要的，因此这两种方式会导致终端功耗的增加，造成终端资源的浪费。为此，本公开实施例提供了一种系统信息变更通知方法，来准确告知终端需要发生变更的系统信息，从而降低终端功耗，节省终端资源。
最后，对本公开实施例涉及的实施环境进行说明。
图1是根据一示例性实施例示出的一种实施环境的示意图。参照图1，该实施环境包括：基站101和终端102，基站101与终端102之间可以通过无线连接进行通信。基站101可以广播多个系统信息，且在该多个系统信息中存在需要发生变更的系统信息时，向终端102发送变更通知信息。终端102可以接 收基站101广播的多个系统信息和基站101发送的变更通知信息，且在接收到该变更通知信息时，可以基于该变更通知信息确定该多个系统信息中需要发生变更的系统信息，并对需要发生变更的系统信息进行更新。
图2是根据一示例性实施例示出的一种系统信息变更通知方法的流程图，该方法应用于基站。如图2所示，该方法包括以下步骤。
在步骤201中，当多个系统信息中存在需要发生变更的系统信息时，生成变更指示序列，变更指示序列用于指示需要发生变更的系统信息。
在步骤202中，基于变更指示序列，生成变更通知信息。
在步骤203中，将变更通知信息发送给终端，由终端基于变更通知信息确定需要发生变更的系统信息。
在本公开实施例中，当基站的多个系统信息中存在需要发生变更的系统信息时，可以生成变更指示序列，并基于该变更指示序列，生成变更通知信息，进而将该变更通知信息发送给终端。由于变更指示序列用于指示需要发生变更的系统信息，因此，终端接收到该变更通知信息后，将能够基于该变更通知信息准确确定需要发生变更的系统信息。此时终端后续仅需对需要发生变更的系统信息进行更新，对不需要发生变更的系统信息则无需进行更新，从而可以有效减少终端功耗，节省终端资源。
可选地，生成变更指示序列，包括：
对于多个系统信息中的每个系统信息，当系统信息需要发生变更时，将系统信息在变更指示序列中对应的元素设置为指定值；
当系统信息不需要发生变更时，将系统信息在变更指示序列中对应的元素设置为除指定值之外的值；
按照多个系统信息的指定顺序，将多个系统信息在变更指示序列中对应的元素组成变更指示序列。
可选地，生成变更指示序列，包括：
基于多个系统信息中需要发生变更的至少一个系统信息的信息标识，从存储的信息标识与指示序列之间的对应关系中，获取对应的指示序列作为变更指示序列。
可选地，基于变更指示序列，生成变更通知信息，包括：
将指定信息的指定域中的内容设置为变更指示序列，得到变更通知信息； 或者，
使用变更指示序列对指定信息进行加扰，得到变更通知信息。
可选地，将变更通知信息发送给终端之前，还包括：
将存储的信息标识与指示序列之间的对应关系发送给终端。
上述所有可选技术方案，均可按照任意结合形成本公开的可选实施例，本公开实施例对此不再一一赘述。
图3是根据一示例性实施例示出的一种系统信息变更通知方法的流程图，该方法应用于终端。如图3所示，该方法包括以下步骤。
在步骤301中，接收基站发送的变更通知信息，变更通知信息为基站基于变更指示序列生成得到，变更指示序列用于指示需要发生变更的系统信息。
在步骤302中，基于变更通知信息，确定变更指示序列。
在步骤303中，基于变更指示序列，确定需要发生变更的系统信息。
在本公开实施例中，基站可以基于变更指示序列，生成变更通知信息，并将该变更通知信息发送给终端，以通知终端具体是哪个系统信息需要发生变更。终端接收到基站发送的变更通知信息后，可以基于该变更通知信息确定变更指示序列。由于该变更指示序列用于指示需要发生变更的系统信息，所以此时终端可以基于该变更指示序列，准确确定需要发生变更的系统信息。此时终端后续仅需对需要发生变更的系统信息进行更新，对不需要发生变更的系统信息则无需进行更新，从而可以有效减少终端功耗，节省终端资源。
可选地，基于变更通知信息，确定变更指示序列，包括：
将变更通知信息的指定域中的内容确定为变更指示序列；或者，
对于存储的多个指示序列中的每个指示序列，使用指示序列对变更通知信息进行解扰；当解扰得到的信息为指定信息时，将指示序列确定为变更指示序列。
可选地，基于变更指示序列，确定需要发生变更的系统信息，包括：
基于多个系统信息的指定顺序，从多个系统信息中确定变更指示序列中的各个元素对应的系统信息；

当元素不为指定值时，确定元素对应的系统信息不需要发生变更。
可选地，基于变更指示序列，确定需要发生变更的系统信息，包括：
基于变更指示序列，从存储的信息标识与指示序列之间的对应关系中，获取对应的至少一个信息标识；
对于至少一个信息标识中的每个信息标识，确定信息标识所标识的系统信息需要发生变更。
可选地，基于变更指示序列，从存储的信息标识与指示序列之间的对应关系中，获取对应的至少一个信息标识之前，还包括：
接收基站发送的信息标识与指示序列之间的对应关系。
上述所有可选技术方案，均可按照任意结合形成本公开的可选实施例，本公开实施例对此不再一一赘述。
图4是根据一示例性实施例示出的一种系统信息变更通知方法的流程图。如图4所示，该方法包括以下步骤。
在步骤401中，当基站的多个系统信息中存在需要发生变更的系统信息时，生成变更指示序列，该变更指示序列用于指示需要发生变更的系统信息。
需要说明的是，该多个系统信息的类型不同，如该多个系统信息可以包括MIB和多个SIB等，本公开实施例对此不作限定。
其中，生成变更指示序列的操作可以通过如下两种方式实现。
第一种方式：对于该多个系统信息中的每个系统信息，当该系统信息需要发生变更时，将该系统信息在变更指示序列中对应的元素设置为指定值；当该系统信息不需要发生变更时，将该系统信息在变更指示序列中对应的元素设置为除指定值之外的值；按照该多个系统信息的指定顺序，将该多个系统信息在变更指示序列中对应的元素组成变更指示序列。
需要说明的是，指定值和该多个系统信息的指定顺序均可以预先进行设置。
例如，该多个系统信息的指定顺序为系统信息1、系统信息2，指定值为1。假设系统信息1需要发生变更，系统信息2不需要发生变更，则可以将系统信息1在变更指示序列中对应的元素设置为1，将系统信息2在变更指示序列中对应的元素均设置为除1之外的值(如0)。之后，按照该多个系统信息的指定顺序，将该多个系统信息在变更指示序列中对应的元素组成变更指示序列10。
需要说明的是，上述第一种方式在实际应用中可以通过bitmap实现，此时 bitmap中的多个位可以与该多个系统信息一一对应，且各个位上的值用于指示各个位对应的系统信息的变更状态。例如，对于bitmap中的每个位，当该位对应的系统信息需要发生变更时，可以将该位上的值设置为指定值(如1)；当该位对应的系统信息不需要发生变更时，可以将该位上的值设置为除指定值之外的值(如0)。如此，根据该多个系统信息的变更状态生成的bitmap即为变更指示序列。
第二种方式：基于该多个系统信息中需要发生变更的至少一个系统信息的信息标识，从存储的信息标识与指示序列之间的对应关系中，获取对应的指示序列作为变更指示序列。
需要说明的是，某个系统信息的信息标识用于唯一标识该系统信息，且该信息标识可以为该系统信息的名称、类型等。
例如，该多个系统信息中需要发生变更的至少一个系统信息为系统信息1和系统信息2，且系统信息1的信息标识为信息标识1，系统信息2的信息标识为信息标识2，则可以基于信息标识1和信息标识2，从如下表1所示的信息标识与指示序列之间的对应关系中，获取对应的指示序列0010作为变更指示序列。
表1
信息标识 指示序列
信息标识1 0000
信息标识2 0001
信息标识1+信息标识2 0010
…… ……
需要说明的是，本公开实施例中，仅以上表1所示的信息标识与指示序列之间的对应关系为例进行说明，上表1并不对本公开实施例构成限定。
在步骤402中，基站基于该变更指示序列，生成变更通知信息。
由于当变更指示序列的生成方式不同时，基于该变更指示序列，生成变更通知信息的方式也有所不同。因此，当该变更指示序列是通过上述步骤401的第一种方式生成时，步骤402可以通过如下第一种方式实现；当该变更指示序列是通过上述步骤401的第二种方式生成时，步骤402可以通过如下第一种方式或第二种方式实现。
第一种方式：将指定信息的指定域中的内容设置为该变更指示序列，得到变更通知信息。
需要说明的是，指定信息可以预先进行设置，如指定信息可以为寻呼信息、寻呼指示信息等，本公开实施例对此不作限定。其中，寻呼指示信息用于指示寻呼信息的接收方式。
另外，指定域可以预先进行设置，且指定域中的内容用于指示需要发生变更的系统信息，如指定域可以为在指定信息中新增加的一个信息域等，该信息域的长度、位置等属性可以预先进行定义。
例如，指定信息为寻呼信息，则此时可以在寻呼信息中新增加一个信息域，并将新增加的信息域作为指定域。之后，将寻呼信息新增加的信息域中的内容设置为该变更指示序列，设置后的寻呼信息即为变更通知信息。
第二种方式：使用该变更指示序列对指定信息进行加扰，得到变更通知信息。
需要说明的是，使用该变更指示序列对指定信息进行加扰，即是指将该变更指示序列作为扰码，将指定信息作为原始数字信号，使用该变更指示序列将指定信息扰乱成新的数字信号的过程，新的数字信号即为变更通知信息。
例如，该变更指示序列为01，指定信息为寻呼信息，则可以使用01对寻呼信息进行加扰，加扰后的寻呼信息即为变更通知信息。
需要说明的是，当变更通知信息是通过上述步骤402的第一种方式生成时，变更通知信息的指定域中的内容即用于指示需要发生变更的系统信息。另外，当变更通知信息是通过上述步骤402的第二种方式生成时，变更通知信息的扰码即用于指示需要发生变更的系统信息。
在步骤403中，基站将该变更通知信息发送给终端。
需要说明的是，如果变更指示序列是通过上述步骤401的第一种方式生成，则为了便于后续终端接收到变更通知信息时，可以基于该变更通知信息准确确定需要发生变更的系统信息，基站将该变更通知信息发送给终端之前，还可以将上述步骤401的第一种方式中使用的指定值和该多个系统信息的指定顺序发送给终端，以便终端可以基于指定值、该多个系统信息的指定顺序和该变更通知信息，准确确定需要发生变更的系统信息。
其中，基站将指定值和该多个系统信息的指定顺序发送给终端时，可以通过第一预设信息将指定值和该多个系统信息的指定顺序发送给终端，此时第一 预设信息中携带有指定值和该多个系统信息的指定顺序。当然，基站也可以通过其它方式将指定值和该多个系统信息的指定顺序发送给终端，本公开实施例对此不作限定。
需要说明的是，第一预设信息可以预先进行设置，如第一预设信息可以为系统信息、RRC(Radio Resource Control，无线资源控制)信令、MAC(Media Access Control，媒体介入控制层)CE(Control Element，控制元件)信令、PHY(Physical Layer，物理层)信令等，本公开实施例对此不作限定。
另外，如果变更指示序列是通过上述步骤401的第二种方式生成，则同样为了便于后续终端接收到变更通知信息时，可以基于该变更通知信息准确确定需要发生变更的系统信息，基站将该变更通知信息发送给终端之前，还可以将上述步骤401的第二种方式中使用的信息标识与指示序列之间的对应关系发送给终端，以便终端可以基于该信息标识与指示序列之间的对应关系和该变更通知信息，准确确定需要发生变更的系统信息。
其中，基站将该信息标识与指示序列之间的对应关系发送给终端时，可以通过第二预设信息将该信息标识与指示序列之间的对应关系发送给终端，此时第二预设信息中携带有该信息标识与指示序列之间的对应关系。当然，基站也可以通过其它方式将该信息标识与指示序列之间的对应关系发送给终端，本公开实施例对此不作限定。
需要说明的是，第二预设信息可以预先进行设置，如第二预设信息可以为系统信息、RRC信令、MAC CE信令、PHY信令等，本公开实施例对此不作限定。
在步骤404中，当终端接收到基站发送的变更通知信息时，基于该变更通知信息，确定变更指示序列。
其中，当该变更通知信息是通过上述步骤402的第一种方式生成时，基于该变更通知信息，确定变更指示序列的操作可以通过如下第一种方式实现。当该变更通知信息是通过上述步骤402的第二种方式生成时，基于该变更通知信息，确定变更指示序列的操作可以通过如下第二种方式实现。
第一种方式：将该变更通知信息的指定域中的内容确定为变更指示序列。
由于上述步骤402的第一种方式中是将指定信息的指定域中的内容设置为变更指示序列后得到变更通知信息，因此，此时可以确定该变更通知信息的指定域中的内容为变更指示序列。
第二种方式：对于存储的多个指示序列中的每个指示序列，使用该指示序列对该变更通知信息进行解扰；当解扰得到的信息为指定信息时，将该指示序列确定为变更指示序列。
由于上述步骤402的第二种方式中是通过变更指示序列对指定信息进行加扰后得到变更通知信息，因此，此时可以依次通过存储的多个指示序列对该变更通知信息进行解扰。对于某个指示序列，当使用该指示序列对该变更通知信息进行解扰得到的信息为指定信息时，表明该变更通知信息是使用该指示序列对指定信息加扰得到，则可以确定该指示序列为变更指示序列。
需要说明的是，该多个指示序列可以预先进行设置，如该多个指示序列可以为终端存储的信息标识与指示序列之间的对应关系中的指示序列等。
在步骤405中，终端基于该变更指示序列，确定需要发生变更的系统信息。
需要说明的是，终端基于该变更指示序列，确定需要发生变更的系统信息后，即可在后续直接对需要发生变更的系统信息进行更新，以基于更新后的系统信息准确接入基站来进行通信。此时终端仅会对需要发生变更的系统信息进行更新，对不需要发生变更的系统信息则不会进行更新，从而可以有效减少终端功耗，节省终端资源。
由于变更指示序列的生成方式不同时，基于该变更指示序列，确定需要发生变更的系统信息的方式不同，因此，当变更指示序列是通过上述步骤401的第一种方式生成时，步骤405可以通过如下第一种方式实现；当变更指示序列是通过上述步骤401的第二种方式生成时，步骤405可以通过如下第二种方式实现。
第一种方式：基于多个系统信息的指定顺序，从该多个系统信息中确定该变更指示序列中的各个元素对应的系统信息；对于该变更指示序列中的每个元素，当该元素为指定值时，确定该元素对应的系统信息需要发生变更；当该元素不为指定值时，确定该元素对应的系统信息不需要发生变更。
其中，基于多个系统信息的指定顺序，从该多个系统信息中确定该变更指示序列中的各个元素对应的系统信息时，可以按照该多个系统信息的指定顺序，将该多个系统信息一一确定为该变更指示序列中的多个元素对应的系统信息。
例如，该多个系统信息的指定顺序为系统信息1、系统信息2，该变更指示序列为10。则基于多个系统信息的指定顺序，可以确定该变更指示序列中的 元素1对应的系统信息为系统信息1，确定该变更指示序列中的元素0对应系统信息为系统信息2。假设指定值为1，则可以确定元素1对应的系统信息1需要发生变更，确定元素0对应的系统信息2不需要发生变更。
需要说明的是，指定值和该多个系统信息的指定顺序可以是预先定义的方法，如可以是从通信协议中确定得到；当然，指定值和该多个系统信息的指定顺序也可以是终端在步骤405之前从基站中接收得到，本公开实施例对此不作限定。
第二种方式：基于该变更指示序列，从存储的信息标识与指示序列之间的对应关系中，获取对应的至少一个信息标识；对于该至少一个信息标识中的每个信息标识，确定该信息标识所标识的系统信息需要发生变更。
例如，该变更指示序列为0010，则可以基于该变更指示序列0010，从如上表1所示的信息标识与指定序列之间的对应关系中，获取对应的至少一个信息标识为信息标识1和信息标识2。假设信息标识1用于标识系统信息1，信息标识2用于标识系统信息2，则可以确定系统信息1和系统信息2均需要发生变更。
需要说明的是，该信息标识与指示序列之间的对应关系可以是预先定义的方法，如可以从通信协议中确定得到；当然，该信息标识与指示序列之间的对应关系也可以是终端在步骤405之前从基站中接收得到，本公开实施例对此不作限定。
在本公开实施例中，当基站的多个系统信息中存在需要发生变更的系统信息时，可以生成变更指示序列，并基于该变更指示序列，生成变更通知信息，进而将该变更通知信息发送给终端，以通知终端具体是哪个系统信息需要发生变更。终端接收到基站发送的变更通知信息后，可以基于该变更通知信息确定变更指示序列。由于该变更指示序列用于指示需要发生变更的系统信息，所以此时终端可以基于该变更指示序列，准确确定需要发生变更的系统信息。此时终端后续仅需对需要发生变更的系统信息进行更新，对不需要发生变更的系统信息则无需进行更新，从而可以有效减少终端功耗，节省终端资源。
