由于北斗短报文卫星在实时运动，因此，卫星信道信息、以及卫星的波束信息在不断变化。这样，北斗网络设备中的相关参数也需要随着卫星信道信息、波束信息的变化做相应适配。同时，北斗通信系统中的通信协议栈参数也需要根据协议版本演进，此外鉴权信息(例如鉴权服务器域名地址)、运营商公共陆地移动网络(public land mobile network，PLMN)也存在变更的可能性。这样，终端也需要及时更新相关参数，才不会影响终端与北斗网络设备之间的通信性能。
因此，在北斗网络设备中的相关参数更新后，如何使得终端100能够及时更新相关参数是亟待解决的问题。

下面介绍本申请实施例提供的一种北斗通信系统10。
图1示出了本申请实施例中提供的一种北斗通信系统10的架构示意图。
如图1所示，北斗通信系统10可以包括终端100、北斗短报文卫星21、北斗网络设备200、短消息中心25和终端300。可选的，该北斗通信系统10还可以包括紧急救援平台26、紧急救援中心27。

终端300也可以通过传统的蜂窝通信网络，将短消息发送给短消息中心25。短消息中心25可以将终端300的短消息转发给北斗网络设备200。北斗网络设备200可以将终端300的短消息通过北斗短报文卫星21中继发送给终端100。
其中，上述北斗网络设备200可以包括北斗地面收发站22、北斗中心站23和北斗短报文融合通信平台24。其中，北斗地面收发站22可以包括分别具有发送功能的一个或多个设备和具有接收功能的一个或多个设备，或者可以包括具有发送功能和接收功能的一个或多个设备，此处不作限定。北斗地面收发站22可用于北斗网络设备200在物理(physical layer protocol，PHY)层对数据的处理功能。北斗中心站23可用于北斗网络设备200在卫星链路控制(satellite link control protocol，SLC)层和消息数据汇聚(message data convergence protocol，MDCP)层对数据的处理功能。北斗短报文融合通信平台24可用于在应用(application layer protocol，APP)层对数据的处理功能。
其中，由于北斗通信系统10是通过卫星链路进行通信，其主要特性是：时延长(单向约270ms)，链路损耗大。当前北斗通信系统10支持的业务主要是突发短消息业务，不支持链接状态管理、移动性管理和广播控制信息等。
其中，北斗网络设备200的工作模式可以是双工模式，可以同时收发数据。
在本申请实施例中，终端100向北斗网络设备200发送数据可以称为入站，终端100向北斗网络设备200发送的数据可以称为入站数据。北斗网络设备200向终端100发送数据可以称为出站，北斗网络设备200向终端100发送的数据可以称为出站数据。如图2所示，终端100可以将入站数据发送给北斗短报文卫星21，然后经由北斗短报文卫星21将入站数据发送给北斗地面收发站22，北斗地面收发站22可以将入站数据发送给北斗中心站23。北斗网络设备200中的北斗中心站23可以向北斗地面收发站22发送出站数据。然后，北斗地面收发站22将出站数据发送给北斗短报文卫星21，经由北斗短报文卫星21发送给终端100。
下面介绍本申请实施例中提供的一种北斗通信系统10的入站数据的协议封装架构。
图3示出了本申请实施例中提供的一种北斗通信系统10的入站数据的协议封装架构示意图。
如图3所示，终端100上的北斗报文传输协议层可以分为应用层(application layer protocol，APP)、消息数据汇聚层(message data convergence protocol，MDCP)、卫星链路控制层(satellite link control protocol，SLC)和物理层(physical layer protocol，PHY)。
终端100发送数据给北斗网络设备200时，终端100上的北斗报文传输协议的工作流程可以如下：
在APP层，终端100可以将原始数据通过压缩算法，压缩成压缩数据，并在压缩数据前面添加压缩指示字段，其中，压缩指示字段可用于表示该压缩数据的压缩算法类型。之后，终端100可以将压缩数据加密，得到加密后数据，并在加密后数据的头部添加加密算法字段，该加密算法字段用于表示该加密后的数据的加密算法类型。终端100可以将加密后数据、压缩指示字段、加密指示字段封装成应用层报文下发给MDCP层。其中，该应用层报文包括报文头和报文数据。该报文头中包括压缩指示字段和加密指示字段等等。该报文数据包括上述加密后数据。
可选的，终端100也可以将压缩指示字段和压缩数据一起进行加密，得到加密后数据。
在MDCP层，终端100可以通过层间接口获取到APP层下发的应用层报文，并将应用层报文作为一个MDCP服务数据单元(servicedataunit，SDU)。在MDCP层，终端100可以在MDCP SDU的尾部添加填充数据(padding)至指定长度，并在MDCP SDU的头部添加冗余长度指示字段。该冗余长度指示字段可用于表示该填充数据的长度。终端100可以将填充 数据以及增加冗余长度指示字段之后的MDCP SDU，拆分成一个或多个固定长度的MDCP分段数据(M_segement)，并在每个MDCP分段数据的头部添加后继指示字段，得到MDCP协议数据单元(protocoldataunit，PDU)，即MDCP PDU包括M_segement和后继指示字段。其中，后继指示字段可用于表示当前的MDCP PDU是连续发送的多个MDCP PDU的起始MDCP PDU或中间MDCP PDU或最后一个MDCP PDU；或者是单独发送的一个MDCP PDU。
在SLC层，终端100可以通过层间接口获取到MDCP层下发的MDCP PDU，作为SLC SDU。在SLC层，终端100可以将SLC SDU分段成一个或多个(最多4个)固定长度的SLC分段数据(S_segement)，并在每个S_segement头部添加帧头信息，得到SLC PDU。其中，帧头信息中包括服务数据单元交替指示(service data unit alternated Indicator，SAI)字段、帧总数字段和帧序号字段。
其中，SAI字段可用于表示该SLC PDU是否属于一个未发送过的SLC SDU。
帧总数字段，可用于表示该SLC PDU所属的SLC SDU中包括SLC PDU的总数量。
帧序号字段，可用于表示该SLC PDU在所属的SLC SDU中的序号。
在PHY层，终端100可以通过层间接口获取到SLC层下发的SLC PDU，作为PHY层的编码块(code block)，并在code block的头部添加同步头，在code block的尾部添加校验位字段。其中，在上述北斗通信系统10中，可以采用循环冗余校验(cyclic redundancy check，CRC)对编码块进行校验，因此，该校验位字段中可以包括CRC码。终端100可以code block和校验位字段进行编码(例如polar编码)，得到编码数据(coded data)，再在coded data中插入导频，得到导频编码数据(pilot+data)。然后，终端100通过底层硬件对同步头和导频编码数据依次进行调制得到调制数据(modulated data)。终端100可以对调制数据进行扩频，得到扩频调制数据(spread+modulated data)。终端100可以将扩频调制数据发送给北斗短报文卫星21，经由北斗短报文卫星21中继转发给北斗网络设备200。
下面介绍本申请实施例中提供的一种北斗通信系统10的入站数据的协议解析架构。
图4示出了本申请实施例中提供的一种北斗通信系统10的入站数据的协议解析架构示意图。
如图4所示，北斗网络设备200的北斗短报文传输协议层可以分为应用层(application layer protocol，APP)、消息数据汇聚层(message data convergence protocol，MDCP)、卫星链路控制层(satellite link control protocol，SLC)和物理层(physical layer protocol，PHY)。其中，北斗网络设备200可以包括北斗地面收发站22、北斗中心站23和北斗短报文融合通信平台24。北斗地面收发站22可用于负责PHY层的协议处理。北斗中心站23可用于负责SLC层和MDCP层的协议处理。北斗短报文融合通信平台24可用于负责APP层的协议处理。
北斗网络设备200在接收到终端100发送的数据时，北斗网络设备200的北斗短报文传输协议层的工作流程可以如下：
在PHY层，北斗网络设备200可以获取到终端100发送的经过调制和扩频后的导频编码数据。北斗网络设备200可以对接收到的扩频调制数据(spread+modulated data)进行解扩频，得到调制数据(modulated data)。然后，北斗网络设备200可以对调制数据进行解调，得到导频编码数据(pilot+data)。接着，北斗网络设备200去除导频编码数据中的导频信息，得到编码数据(code data)。然后，北斗网络设备200可以对编码数据进行解码，并通过校验位字段中的校验数据验证编码块(code block)的完整性。若完整，则北斗网络设备200可以提取出编码块(code block)，通过层间接口呈递给SLC层，作为SLC层的SLC PDU。
在SLC层，北斗网络设备200可以基于SLC PDU的帧头信息，将属于同一个SLC SDU的SLC PDU拼接成一个SLC SDU。北斗网络设备200可以将SLC SDU通过层间接口呈递给MDCP层，作为MDCP层的MDCP PDU。
在MDCP层，北斗网络设备200可以将属于同一个MDCP SDU的所有MDCP PDU拼接成一个MDCP SDU。北斗网络设备200可以将MDCP SDU通过层间接口呈递到APP层，作为APP层接收到的应用层报文。
在APP层，北斗网络设备200可以基于应用层报文的报文头，对应用层报文进行解密、解压缩，得到原始数据。
本申请实施例中，上述协议处理过程仅为示例说明，本申请对协议处理的具体操作不作限定。
下面介绍本申请实施例中提供的一种北斗通信系统10的出站数据的协议封装架构。
图5示出了本申请实施例中提供的一种北斗通信系统10的出站数据的协议封装架构示意图。
如图5所示，北斗网络设备200中的北斗短报文传输协议层可以应用层(application layer protocol，APP)、消息数据汇聚层(message data convergence protocol，MDCP)、卫星链路控制层(satellite link control protocol，SLC)和物理层(physical layer protocol，PHY)。其中，北斗网络设备200可以包括北斗地面收发站22、北斗中心站23和北斗短报文融合通信平台24。北斗地面收发站22可用于负责PHY层的协议处理。北斗中心站23可用于负责SLC层和MDCP层的协议处理。北斗短报文融合通信平台24可用于负责APP层的协议处理。
北斗网络设备200发送数据给终端100时，北斗网络设备200中的北斗短报文传输协议的工作流程可以如下：
在APP层，北斗网络设备200可以将原始数据通过压缩算法，压缩成压缩数据，并在压缩数据前面添加压缩指示字段，其中，压缩指示字段可用于表示该压缩数据的压缩算法类型。之后，北斗网络设备200可以将压缩数据加密，得到加密后数据，并在加密后数据的头部添加加密算法字段，该加密算法字段用于表示该加密后的数据的加密算法类型。北斗网络设备200可以将加密后数据、压缩指示字段、加密指示字段封装成应用层报文下发给MDCP层。其中，该应用层报文可以包括报文头和报文数据。该报文头中可以包括压缩指示字段、加密指示字段等等。该报文数据包括上述加密后数据。
可选地，在一种可能的实现方式中，北斗网络设备200在MDCP层将MDCP SDU切分成多个MDCP PDU，北斗网络设备200可以将多个MDCP PDU一并传输到北斗网络设备200的SLC层。
在MDCP层，北斗网络设备200可以通过层间接口获取到APP层下发的应用层报文，并将应用层报文作为一个MDCP SDU。在MDCP层，北斗网络设备200可以将一个MDCP SDU拆分成一个或多个固定长度的MDCP分段数据(M_segement)，并在每个MDCP分段数据的头部添加后继指示字段，得到MDCP PDU，即MDCP PDU包括M_segement和后继指示字段。其中，后继指示字段可用于表示当前的MDCP PDU是连续发送的多个MDCP PDU的起始MDCP PDU或中间MDCP PDU或最后一个MDCP PDU；或者是单独发送的一个MDCP PDU。
在SLC层，北斗网络设备200可以通过层间接口获取到MDCP层下发的MDCP PDU，作为SLC SDU。在SLC层，北斗网络设备200可以将SLC SDU分段成一个或多个(最多4 个)固定长度的SLC分段数据(S_segement)，并在每个S_segement头部添加帧头信息，得到SLC PDU。
在PHY层，北斗网络设备200可以通过层间接口获取到SLC层下发的SLC PDU。北斗网络设备200可以从SLC层获取到一个用户或多个用户的SLC PDU。北斗网络设备200可以将多个用户的SLC PDU拼接在一起，再加上物理帧的帧头(例如版本号)作为PHY层的编码块(code block)，并在code block的尾部添加校验位(例如，循环冗余校验(cyclic redundancy check，CRC)码)，并对code block和CRC码进行编码(例如polar编码)，编码后的物理帧加上保留段可以组成一个固定长度的物理时隙的电文支路(S2C_d支路)的编码数据。其中，北斗网络设备200可以将一个用户的多个SLC PDU分别放到不同的物理帧中。然后，北斗网络设备200将S2C_d支路的编码数据和导频支路(S2C_p支路)的导频信息组成导频编码数据，即出站数据。北斗网络设备200可以将出站数据发送给北斗短报文卫星21，经由北斗短报文卫星21中继转发给终端100。
可以理解的是，S2C_p支路的导频信息与卫星波束相关。当卫星波束号时已知信息时，S2C_p支路的导频信息也是已知的，无需解码的。而S2C_d支路的编码数据是需要解码的。
下面介绍本申请实施例中提供的一种北斗通信系统10的出站数据的协议解析架构。
图6示出了本申请实施例中提供的一种北斗通信系统10的出站数据的协议解析架构示意图。
如图6所示，终端100的北斗短报文传输协议层可以分为应用层(application layer protocol，APP)、消息数据汇聚层(message data convergence protocol，MDCP)、卫星链路控制层(satellite link control protocol，SLC)和物理层(physical layer protocol，PHY)。
终端100在接收到北斗网络设备发送的数据时，终端100的北斗短报文传输协议层的工作流程可以如下：
在PHY层，终端100可以获取到北斗网络设备200发送的经过调制和扩频后的导频编码数据。终端100可以对接收到的扩频调制数据(spread+modulated data)进行解扩频，得到调制数据(modulated data)。然后，终端100可以对调制数据进行解调，得到导频编码数据(pilot+data)。接着，终端100可以去除导频编码数据中的导频信息，得到编码数据(code data)。然后，终端100可以对编码数据进行解码，并通过校验位字段中的校验数据验证编码块(code block)的完整性。若完整，则终端100可以提取出编码块(code block)，通过层间接口呈递给SLC层，作为SLC层的SLC PDU。
这里，该导频编码数据即为上述北斗网络设备200发送的出站数据，该出站数据由S2C_d支路的编码数据和导频支路(S2C_p支路)的导频信息组成。
在SLC层，终端100可以基于SLC PDU的帧头信息，将属于同一个SLC SDU的SLC PDU拼接成一个SLC SDU。终端100可以将SLC SDU通过层间接口呈递给MDCP层，作为MDCP层的MDCP PDU。
在MDCP层，终端100可以将属于同一个MDCP SDU的所有MDCP PDU拼接成一个MDCP SDU。终端100可以将MDCP SDU通过层间接口呈递到APP层，作为APP层接收到的应用层报文。
在APP层，终端100可以基于应用层报文的报文头，对应用层报文进行解密、解压缩，得到原始数据。
本申请实施例中，上述协议处理过程仅为示例说明，本申请对协议处理的具体操作不作 限定。
在本申请实施例示出的北斗通信系统10中，北斗网络设备200和终端100都配置有北斗通信系统10中的相关参数(简称为北斗通信参数)。北斗通信参数可以用于终端100在北斗网络下与北斗网络设备200进行通信。例如，终端100中配置的北斗通信参数可以用于指示终端100向北斗网络设备200发送数据的格式、速率，以及可以用于指示终端100如何封装数据、如何解析北斗网络设备200发送给终端100的数据等等。北斗网络设备200中配置的北斗通信参数可以用于指示北斗网络设备200发送数据的格式、速率，以及可以用于指示北斗网络设备200如何封装数据、如何解析终端100发送的数据等等。
在本申请实施例中，携带有第一标识的北斗通信参数可以称为关键参数，未携带第一标识的北斗通信参数可以称为非关键参数。在一些例子中，非关键参数对北斗通信系统10的通信性能影响较大，非关键参数对北斗通信系统10的通信性能影响不大。
示例性地，图7示出北斗通信系统10中的北斗通信参数。如图7所示，在北斗通信系统10中，北斗通信参数可以包括：卫星星历轨道参数、协议栈参数、卫星信道参数、鉴权信息参数、卫星波束信息参数、北斗网络设备信息参数、终端能力信息参数、压缩信息参数、应用信息参数等等。
其中，卫星星历轨道参数可以用于指示卫星的运动速率和运动方向、坐标等。

卫星波束信息参数可以用于指示卫星波束的覆盖范围、卫星波束的频率等。
协议栈参数可以用于指示终端100与北斗网络设备200之间的通信传输性能，该协议栈参数可以包括影响数据入站和数据出站通信传输性能的相关参数，例如SLC层中出站和入站的传输模式、重传次数、最大帧数等参数。
鉴权信息参数用于确保北斗通信系统中的鉴权功能生效，该鉴权信息参数可以包括鉴权服务器域名地址、运营商公共陆地移动网络(publiclandmobilenetwork，PLMN)。
北斗网络设备信息参数可以用于指示北斗网络设备的传输能力。例如，该北斗网络设备信息参数可以包括北斗网络设备的发射功率、北斗短报文的长度(例如帧头长度、帧头设计等等)。
终端能力信息参数可用于指示终端100的传输能力，该终端能力信息参数可以包括终端的发射功率、终端支持的带宽等等参数。
应用信息参数指示应用层的相关参数，例如加密参数、压缩参数、鉴权码的使用等等。
压缩信息参数可以用于指示应用层报文中或者SLC层用户帧中压缩某个字段的信息，例如SLC层用户帧中用于指示发送方号码的字段(例如用户ID字段)的压缩、应用层报文中用于指示接收方号码的字段的压缩。
图7中示出的北斗通信系统10中的一些相关参数中(简称为北斗通信参数)，其中，卫星星历轨道参数、卫星信道参数、卫星波束信息参数、以及协议栈参数中可以携带有第一标识。即，卫星星历轨道参数、卫星信道参数、卫星波束信息参数、以及协议栈参数可以称为关键参数。其他的参数，如鉴权信息参数、北斗网络设备信息参数、终端能力信息参数、压缩信息参数、应用信息参数等可以称为非关键参数。
北斗通信系统10中的一些相关参数会发生变化，因此，北斗网络设备200和终端100中配置的上述参数需要更新。例如，北斗通信系统10中的卫星星历轨道参数、卫星信道参数、卫星波束信息参数会因为卫星的移动而发生变化。协议栈参数、鉴权信息参数、压缩信息参 数、应用信息参等参数可能会随着北斗通信系统10中通信协议的升级而变化。当北斗网络设备200的参数和终端100中的参数不一致时，会影响终端100和北斗网络设备200之间的正常通信。例如，终端100可能无法正确的解码出北斗网络设备200发送的数据，北斗网络设备200也无法正确解码出终端100发送的数据。这样，当北斗网络设备200中的参数更新后，终端100也需要及时更新参数。
在本申请实施例中，终端100可以通过云服务器或者附近的北斗终端获取更新后的参数。云服务器可以从北斗参数发布服务器29中获取更新后的参数。

基于上述图8中提供的参数更新系统20，本申请实施例提供一种北斗通信系统中的参数更新方法，该方法可以包括：首先，在终端100符合第一条件的情况下，终端100获取终端100本地配置的第一北斗通信参数的第一版本信息；其中，第一条件可以为终端100在预设时长内离开常驻地。然后，终端100再获取云服务器400中的第二北斗通信参数的第二版本 信息。在第二版本信息中指示的版本比第一版本信息中指示的版本新的情况下，终端100获取云服务器400中的第二北斗通信参数。最后，终端100将第一北斗通信参数更新为第二北斗通信参数。
图9示例性地示出了本申请实施例提供的一种北斗通信系统中的参数更新方法流程示意图。如图9所示，该北斗通信系统中的参数更新方法可以包括如下步骤：
S901、北斗参数发布服务器29更新北斗通信参数，得到更新后的北斗通信参数P1和北斗通信参数P1的版本信息M1。
控制系统28可以在接收到更新参数的指示后，向北斗参数发布服务器29发送最新版本的北斗通信参数P1以及该北斗通信参数P1的版本信息M1。控制系统28还可以指示北斗参数发布服务器29中保存的北斗通信参数更新为北斗通信参数P1、并保存该北斗通信参数P1的版本信息M1。
可选地，控制系统28接收到的更新参数的指示可以是研发人员在控制系统28中输入的指令。
可以理解的是，北斗通信参数P1可以包括卫星星历轨道参数、协议栈参数、卫星信道参数、卫星波束信息参数、北斗网络设备信息参数、终端能力信息参数、压缩信息参数、应用信息参数中的一项或多项。
版本信息M1可以包括北斗通信参数P1的更新时间(例如2021/10/10、或者4天前等)，版本号(例如，1.2.1、或者version1.0等)等。可以理解的是，本申请实施例对版本信息M1中的更新时间的形式，以及版本号的具体形式不作限定。
进一步地，若北斗通信参数P1是关键参数，则北斗通信参数P1携带有第一标识，第一标识用于指示该北斗通信参数P1为关键参数。
在一种可能的实现方式中，每个北斗通信参数P1可以保存在一个文件中。第一标识可以存在于保存该北斗通信参数P1文件的文件名中。例如，第一标识可以是保存该北斗通信参数P1文件的文件名的后缀。举例来说，保存该北斗通信参数P1的文件名为“协议栈参数.key parameter”，其中，“keyparameter”为文件名“协议栈参数.key parameter”的后缀。第一标识即为“keyparameter”。可以理解的是，本申请实施例对第一标识的具体内容和具体形式不作限定。
S902、若北斗通信参数P1为关键参数，则北斗参数发布服务器29将北斗通信参数P1和版本信息M1发送给云服务器400；若北斗通信参数P1为非关键参数，则北斗参数发布服务器29在预设时间间隔T1后将北斗通信参数P1和版本信息M1发送给云服务器400。
北斗参数发布服务器29可以根据北斗通信参数P1是否存在第一标识，确定北斗通信参数P1是否为关键参数。若北斗通信参数P1中存在第一标识，则北斗参数发布服务器29可以确定该北斗通信参数P1为关键参数。若北斗通信参数P1中不存在第一标识，则北斗参数发布服务器29可以确定该北斗通信参数P1为非关键参数。
若北斗通信参数P1为关键参数，则北斗参数发布服务器29立刻将北斗通信参数P1和版本信息M1发送给云服务器400。若北斗通信参数P1为非关键参数，则北斗参数发布服务器29在预设时间间隔T1后将北斗通信参数P1和版本信息M1发送给云服务器400。预设时间间隔T1可以是一周(又可以称为一个星期、或者7天)、两周(又可以称为两个星期、或14天)、一个月、两个月等等。可以理解的是，本申请实施例对预设时间间隔T1的具体取值不作限定。
在一种可能的实现方式中，北斗参数发布服务器29中可以设置有更新参数的定时器。北 斗参数发布服务器29可以启动更新参数的定时器，在定时器的预设周期内更新参数。
S903、云服务器400接收北斗通信参数P1和版本信息M1，将保存的北斗通信参数更新为北斗通信参数P1，保存版本信息M1。
云服务器400可以接收到北斗参数发布服务器29发送的北斗通信参数P1和版本信息M1。云服务器400将云服务器400中保存的北斗通信参数更新为北斗通信参数P1，并保存该北斗通信参数P1的版本信息M1。可以理解的是，若北斗通信参数P1为卫星星历轨道参数，那么云服务器400将云服务器400保存的卫星星历轨道参数更新为北斗通信参数P1。
在一种可能的方式中，北斗参数发布服务器29可以先将北斗通信参数P1的版本信息M1发送给云服务器400。若云服务器400确定该版本信息M1指示的版本比云服务器400中存储的北斗通信参数的版本新，则云服务器400向北斗参数发布服务器29获取北斗通信参数P1。
在一种可能的实现方式中，若云服务器400确定该版本信息M1指示的版本与云服务器400中存储的北斗通信参数的版本相同，则云服务器400不向北斗参数发布服务器29获取北斗通信参数P1。S904、终端100在符合第一条件的情况下，获取终端100本地配置的北斗通信参数的版本信息M0。
终端100在符合第一条件的情况下，获取终端100本地配置的北斗通信参数的版本信息M0。第一条件可以是终端100在预设时长内离开常驻地(例如，离开居住地所在的城市、或者工作地所在的城市)。
终端100可以根据终端100连接的网络、以及位置信息、用户出行信息(例如购票信息、日程安排)等信息确定终端100是否满足第一条件。具体地，终端100可以根据终端100连接的网络是否为常驻网络(即终端100经常连接的网络，例如，家中的Wi-Fi网络)，若不是常驻网络，则终端100可以根据位置信息和用户出行信息确定是否离开常驻地。若终端100的位置信息指示终端100不在常驻地，终端100可以确定终端100离开常驻地。或者终端100中的用户出行信息中指示终端100在第一日期要去另一个城市，或者日程安排中指示终端100在第一日期要去另一个城市，那么终端100可以确定终端100是否在预设时长内离开常驻地。
预设时长可以有终端100的系统配置，预设时长可以是30分钟，也可以是20分钟，本申请实施例对该预设时长的具体取值不作限定。
举例来说，终端100的用户的居住地在A市，工作地也在A市。终端100在10月10日9点检测到终端100连接的网络不是常驻网络，且终端100中有10月10日9点30从A市到B市的购票信息。那么终端100可以确定终端100在10月10日9点30离开常驻地。以预设时长为30分钟为例，即终端100可以在10月10日9点开始执行步骤S904。
这样，终端100离开常驻地之前，终端100可以及时更新终端100的北斗通信参数。并且，可以避免由于终端100中的北斗通信参数的版本与北斗网络设备200中的北斗通信参数版本不一致，而导致终端100在无蜂窝网络覆盖的区域，无法正常与北斗网络设备200通信的情况的发生。
S905、终端100向云服务器400发送获取云服务器400中北斗通信参数P1的版本信息M1的请求。

S907、终端100确定版本信息M1指示的版本比版本信息M0指示的版本新。
终端100可以接收到云服务器400发送的版本信息M1。终端100可以基于版本信息M0和版本信息M1来确定哪一个北斗通信参数的版本更新。
终端100可以基于版本信息M1中的版本号以及版本信息M0中的版本号，确定哪一个北斗通信参数的版本更新。若版本信息M1中的版本号高于版本信息M0中的版本号，则终端100确定版本信息M1指示的版本比版本信息M0指示的版本新。若版本信息M1中的版本号低于版本信息M0中的版本号，则终端100确定版本信息M0指示的版本比版本信息M1指示的版本新。
举例来说，若版本信息M0中的版本号为1.0，版本信息M1中的版本号为2.0，终端100可以确定版本信息M1指示的版本比版本信息M0指示的版本新。若版本信息M0中的版本号为2.0，版本信息M1中的版本号为1.0，终端100可以确定版本信息M0指示的版本比版本信息M1指示的版本新。
可选地，终端100基于版本信息M1中的更新时间、以及版本信息M0中的更新时间，确定哪一个北斗通信参数的版本更新。若版本信息M1中的更新时间晚于版本信息M0中的更新时间，则终端100确定版本信息M1指示的版本比版本信息M0指示的版本新。若版本信息M1中的更新时间早于版本信息M0中的更新时间，则终端100确定版本信息M0指示的版本比版本信息M1指示的版本新。
举例来说，若版本信息M1中的更新时间为2021/10/10，版本信息M0中的更新时间为2021/9/1，则终端100确定版本信息M1指示的版本比版本信息M0指示的版本新。若版本信息M1中的更新时间为2021/8/10，版本信息M0中的更新时间为2021/9/1，则终端100确定版本信息M0指示的版本比版本信息M1指示的版本新。
可以理解的是，本申请实施例中的版本号是指每个北斗通信参数的版本号。云服务器400或者终端100以及北斗参数发布服务器29中保存的不同的北斗通信参数，其对应的版本号可以不同。示例性地，终端100中保存的卫星星历轨道参数的版本号可以与协议栈参数的版本号不同。
在终端100确定版本信息M1指示的版本比版本信息M0指示的版本新的情况下，终端100可以执行下述步骤S908-步骤S910。在终端100确定版本信息M0指示的版本比版本信息M1指示的版本新、或者版本信息M0指示的版本与版本信息M1指示的版本相同的情况下，终端100不执行步骤S908-步骤S910。
S908、终端100向云服务器400发送获取云服务器400中北斗通信参数的请求。
终端100可以向云服务器400发送获取云服务器400中北斗通信参数的请求。
S909、云服务器400向终端100发送北斗通信参数P1。
基于终端100发送的请求，云服务器400可以向终端100发送北斗通信参数P1。
在一种可能的实现方式中，北斗通信参数P1中包括全部的北斗通信参数。
可选地，在另一种可能的实现方式中，北斗通信参数P1中仅包括更新的北斗通信参数。
举例来说，若云服务器400中保存北斗通信参数的数量有100个，但本次只有10个北斗通信参数已更新。那么云服务器400发送给终端100的北斗通信参数P1可以包含这100个北斗通信参数。或者云服务器400发送给终端100的北斗通信参数P1仅保存已更新的10个北斗通信参数。
S910、终端100将本地配置的北斗通信参数更新为北斗通信参数P1。
终端100可以接收到云服务器400发送的北斗通信参数P1。终端100可以将本地配置的北斗通信参数更新为北斗通信参数P1。
在一种可能的实现方式中，本申请实施例中的终端100更新北斗通信参数可以指，终端将已有的低版本的北斗通信参数更新高版本的北斗通信参数，和/或终端100增加终端100中未包含的北斗通信参数。
进一步地，在一种可能的实现方式中，若北斗通信参数P1中包含北斗通信参数a，北斗通信参数P0中不包含北斗通信参数a，那么终端100中也可以获取该北斗通信参数a，并配置该北斗通信参数a。
可选地，在一些可能的实现方式中，终端100直接向云服务器400获取北斗通信参数P1，然后将终端100的北斗通信参数P0更新为北斗通信参数P1。即终端100无需执行上述步骤S905-步骤S909。
这样，终端100可以在离开常驻地前，及时更新终端100中本地配置的北斗通信参数。并且，可以避免由于终端100中的北斗通信参数的版本与北斗网络设备200中的北斗通信参数版本不一致，而导致终端100在无蜂窝网络覆盖的区域，无法正常与北斗网络设备200通信的情况的发生。
可以理解的是，终端100先比较北斗通信参数P0的版本信息M0和北斗通信参数P1的版本信息M1，再确定是否是需要获取北斗通信参数P1。这样，可以避免在北斗通信参数P0和北斗通信参数P1的版本一样的情况下，终端100仍然进行参数更新。这样，可以节约终端100的功耗。
在本申请实施例中，终端100可以称为第一终端，服务器500可以称为服务器。北斗通信参数P0可以称为第一北斗通信参数。版本信息M0可以称为第一版本信息。北斗通信参数P1可以称为第二北斗通信参数。版本信息M1可以称为第二版本信息。
在另一些场景中，终端100位于无蜂窝网络覆盖的地区，这样，终端100无法通过蜂窝网络或者Wi-Fi网络向云服务器400获取更新后的北斗通信参数。终端100可以通过附近的终端获取到更新后的北斗通信参数。
本申请实施例提供一种北斗通信系统中的参数更新方法，该方法可以包括：终端100未驻留在蜂窝网络下，终端600未驻留在蜂窝网络下。首先，终端100与终端600建立通信连接；然后，终端100获取终端600中北斗通信参数的版本信息M2。接着，在终端100基于版本信息M2确定终端600中北斗通信参数的版本比终端100中的北斗通信参数的版本新的情况下，终端100获取终端600中的北斗通信参数P2。最后，终端100将本地配置的北斗通信参数更新为北斗通信参数P2。
