当终端设备处于独立组网(standalone)的GNSS模式，终端设备需要手动搜星，单次搜星耗时要12min左右，时延太大，故第三代合作伙伴计划(3rd generation partnership project，3GPP)和开放移动联盟(open mobile alliance，OMA)组织分别针对其做了增强，即推出辅助全球导航卫星系统(assisted-global navigation satellite system，A-GNSS)技术。A-GNSS技术实现上有两种方案，一种方案是终端设备通过控制面的非接入层(non-access stratum，NAS)信令从网络侧位置管理功能设备(location management function，LMF)获取卫星数据，另一种方案是终端设备通过用户面访问因特网(Internet)或运营商定位平台(supl location platform，SPL)网络获取卫星数据。这样，终端设备获取到卫星数据后，可以在几秒内完成搜星，快速完成位置定位或者GNSS测量数据上报。针对第一种方案，3GPP未定义LMF从哪里获取卫星数据，导致在实际部署时候，还是需要依赖第三方服务器给LMF传递卫星数据，即还是需要通过第二种方案实现卫星数据的获取。
但是，为了减少和运营商沟通成本，快速商用提升用户体验，终端设备操作系统以及终端设备芯片实际都采用用户面的用户面安全定位(secure user plane location，SUPL)协议，从各自自建的A-GNSS服务器获取信息，绕过3GPP相关标准。

在图1所示的架构中，各设备之间可以通过图中所示的接口通信。如图1所示，下一代网络(Next generation，NG)1接口(简称N1接口)为终端设备与移动性管理网元之间的参考点；N2接口为(R)AN和移动性管理网元的参考点，用于非接入层(non-access stratum，NAS)消息的发送等；NL1接口为移动性管理网元和位置管理网元之间的参考点，用于位置定位请求和响应消息的发送等。此外，其他接口与各设备之间的关系如图1中所示，为了简洁，这里不一一详述。
图1中N1、N2、NL1、NL7、N8、NL2、N51、N52、NL6、N33、Le等为接口序列 号。这些接口序列号的含义可参见第三代合作伙伴计划(3rd generation partnership project，3GPP)标准协议中定义的含义，在此不做限制。
需要说明的是，图1中所涉及的各个设备以及设备之间的通信接口的名称是以目前协议中规定的为例进行简单说明的，但并不限定本申请实施例只能够应用于目前已知的通信系统。因此，以目前协议为例描述时出现的标准名称，都是功能性描述，本申请对于设备、接口或信令等的具体名称并不限定，仅表示设备、接口或者信令的功能，可以对应的扩展到其它系统，比如2G、3G、4G或未来通信系统中。
上述图1所示的本申请实施例能够应用的架构仅是一种举例说明，适用本申请实施例的架构并不局限于此，任何能够实现上述各个设备的功能的架构都适用于本申请实施例。
还应理解，上述命名仅为便于区分不同的功能而定义，不应对本申请构成任何限定。本申请并不排除在5G网络以及未来其它的网络中采用其他命名的可能。例如，在6G网络中，上述各个设备中的部分或全部可以沿用5G中的术语，也可能采用其他名称等。图1中的各个设备之间的接口名称只是一个示例，具体实现中接口的名称可能为其他的名称，本申请对此不作具体限定。此外，上述各个设备之间的所传输的消息(或信令)的名称也仅仅是一个示例，对消息本身的功能不构成任何限定。
目前，一般在如图1所示的通信系统中设置第三方服务器(例如A-GNSS服务器)，以便位置管理网元从第三方服务器获取卫星数据。但是，这样不仅绕过3GPP相关标准，终端设备还需要要激活PDU会话且能访问公网后，才支持A-GNSS功能。这样，对于终端设备而言，需要额外激活并维护PDU Session会话相关数据，增加终端设备的成本，以及终端设备和网络复杂度。
因此，本申请实施例提供了一种通信方法，在通信方法中，接入网设备本身可以获取卫星信号，这样，接入网设备可以自己根据卫星信号确定卫星的参数信息，并将参数信息传递给终端设备或位置管理功能设备。或者，接入网设备将卫星信号传递给位置管理功能设备，位置管理功能设备可以根据卫星信号确定卫星的参数信息，并将参数传递给终端设备。进而无需在网络中部署第三方服务器，可以沿用3GPP相关标准，终端设备或位置管理功能设备即可获取到卫星的参数信息，降低了网络的复杂度和成本。此外，对于终端设备而言，无需额外激活并维护PDU Session会话相关数据，且能够快速搜索捕获接入网设备附近上空卫星广播信号并完成定位，降低了终端设备的成本以及耗电量。
此外，当前GNSS基准站的部署规模远远小于接入网设备数量，因此，通过该通信方法，能够依托接入网设备海量部署规模，更进一步快速提升终端设备的搜星和对卫星信号进行测量的能力。这样，该通信方法可以大规模商用于依赖户外高精度定位的应用，比如与无人驾驶相关的应用等。

接入网设备周期性地向位置管理功能设备发送第一信号测量信息。这样，接入网设备可以将最新的第一信号测量信息上报给位置管理功能设备。进一步地，位置管理功能设备周期性地对第一信号测量信息进行处理得到第一参数信息，并周期性地将第一参数信息发给接入网设备。进而接入网设备可以周期性地将第一参数信息发送给终端设备，即接入网设备可以将最新的第一参数信息发送给终端设备，这样终端设备可以根据最新的第一参数信息对卫星的卫星信号进行捕获和测量，提高了对卫星信号捕获和测量的速率，且得到的测量数据的精度也比较高。
在一个示例中，通过S220，接入网设备将第一参数信息发送给终端设备，相应地，终端设备接收接入网设备发送的第一参数信息。那么，在终端设备接收到第一参数信息后，终端设备可以进行定位。
在另一个示例中，通过S220，接入网设备将第一参数信息发送给位置管理功能设备，相应地，位置管理功能设备接收接入网设备发送的第一参数信息。那么，位置管理功能设备基于LPP协议将该第一参数信息传输给终端设备，这样，终端设备接收到第一参数信息后，终端设备可以进行定位。
终端设备可以支持两种辅助模式实现定位。
例如，该两种辅助模式包括基于UE的辅助模式(UE-Based)和UE辅助模式(UE-Assisted)。
其中，基于UE的辅助模式是UE执行GNSS测量并自己使用协助数据(assistance data)对UE的位置计算。
UE辅助模式是UE执行GNSS测量并把测量数据发给位置管理功能设备，以便位置管理功能设备对UE的位置进行计算。
可选地，在终端设备支持基于UE的辅助模式进行定位的情况下，方法200还包括：
S230，终端设备根据S220接收的第一参数信息，对卫星的卫星信号进行测量，得到相应的信号测量信息。
若终端设备接收的第一参数信息是一颗卫星对应一个第一参数信息的情况下，在S230中，终端设备对接收到的第一参数信息的卫星的卫星信号进行测量，得到相应的信号测量信息。
若终端设备接收的第一参数信息是整合了多颗卫星的第一参数信息的内容的情况下，在S230中，终端设备对接收到的第一参数信息中指示的卫星列表中的卫星的卫星信号进行测量，得到相应的信号测量信息。
此时，第一参数信息可以理解为是上文所述的协助数据。
终端设备可以基于接收的第一参数信息，打开终端设备相应的GNSS接收器的通道，快速对终端设备的上空的卫星的卫星信号进行捕获，进而对终端设备的上空的卫星的信号进行测量，得到终端设备的上空卫星的第一信号测量信息。
S240，终端设备根据S230测量得到信号测量信息，确定终端设备的测量位置。
在一个示例中，若在S230中终端设备获取了一颗卫星的多个信号测量信息，那么，终端设备可以根据一颗卫星的多个信号测量信息，获取终端设备的测量位置。
在一个示例中，若在S230中终端设备获取了至少三颗卫星的信号测量信息，那么终端设备可以对至少三颗卫星的信号测量信息进行测量，获取终端设备的测量位置。
例如，首先，终端设备分别根据每颗卫星的信号测量信息，确定每颗卫星发送该信号测量信息的时间，并根据自己接收信号测量信息的时间与每颗卫星发送该信号测量信息的时间之间差值与光速的乘积作为终端设备和每颗卫星之间的距离。然后，终端设备对每颗卫星的第一信号测量信息进行测量，获取每颗卫星的位置，并以每颗卫星的位置为圆心、以终端设备和每颗卫星之间的距离为半径，可得到三个球体，该三个球体的交点即为终端设备的测量位置。
在另一个示例中，若在S230中终端设备获取了至少四颗卫星的信号测量信息，那么，终端设备可以根据至少四颗卫星的信号测量信息，消除终端设备的时间误差，并根据该至少四颗卫星的信号测量信息，获取终端设备的测量位置。
通过S230和S240，由于终端设备获取的是最新的卫星数据，进而终端设备可以快速 对卫星的卫星信号进行捕获和测量，提高了对卫星信号捕获和测量的速率，且得到的测量数据的精度也比较高。
可选地，在终端设备支持UE辅助模式进行定位的情况下，方法200还包括：
S230，终端设备根据S220接收的第一参数信息，对卫星的卫星信号进行测量，得到相应的信号测量信息。具体过程参见上文的描述，这里不再赘述。
S250，终端设备将S230测量得到的信号测量信息发送给位置管理功能设备。
在一个示例中，终端设备可以直接将S230测量得到的第一信号测量信息发送给位置管理功能设备。在另一个示例中，终端设备可以通过接入网设备将S230测量得到的第一信号测量信息发送给位置管理功能设备。
S260，位置管理功能设备根据终端设备发送的信号测量信息，确定终端设备的位置。
S260和S240仅是执行主体不一致，具体过程类似。因此，关于S260相关的描述可以参考上文S240的相关描述，这里不再赘述。
通过S230、S250和S260，由于终端设备获取的是最新的卫星数据，进而终端设备可以快速对卫星的卫星信息进行捕获和测量，提高了对卫星信号捕获和测量的速率，且得到的测量数据的精度也比较高。进而，位置管理功能设备也可以快速并准确地确定出终端设备的位置。
此外，在现有方案中，由于终端设备的位置可能和地面基准站位置距离较远，导致从第三方服务器获取的测量位置和绝对位置之间的修正量不够准确。
因此，本申请实施例还提供了一种通信方法，该通信方法可以将接入网设备的绝对位置和测量位置之间的修正量传输给终端设备或位置管理功能设备。这样可以使得终端设备或位置管理功能设备根据该修正量，对终端设备的测量位置进行修正。由于终端设备和其连接的接入网设备的距离较近，处在同一范围领空，因此，终端设备或位置管理功能设备根据该修正量，对终端设备的测量位置进行修正的结果是更加准确，进而能够辅助终端设备的精准定位。
此外，当前GNSS基准站的部署规模远远小于接入网设备数量，且GNSS基准站的修正量，随着终端设备距离越远，修正效果越差。而通过该通信方法，依托接入网设备海量部署规模，且接入网设备与终端设备距离很近，这样，该通信方法可以大规模商用于依赖户外高精度定位的应用，比如与无人驾驶相关的应用等。

在一些实施例中，若接入网设备获取到至少三颗卫星的第二信号测量信息，接入网设备可以先根据每颗卫星的第二信号测量信息，确定每颗卫星发送该第二信号测量信息对应 的卫星信号的时间，并根据自己接收该第二信号测量信息对应的卫星信号的时间与每颗卫星发送该第二信号测量信息对应的卫星信号的时间之间差值与光速的乘积作为接入网设备和卫星之间的距离。
然后，接入网设备根据每颗卫星的第二信号测量信息，获取每颗卫星的位置，从而根据接入网设备和每颗卫星之间的距离，可得到接入网设备的测量位置。例如，接入网设备可以以每颗卫星的位置为圆心、以接入网设备和每颗卫星之间的距离为半径，可得到三个球体，该三个球体的交点即为接入网设备的测量位置。

例如，如图9所示，该S320包括：
S321c，接入网设备向位置管理功能设备发送第二信号测量信息。
可选地，在接入网设备获取多颗卫星的第二信号测量信息的情况下，接入网设备还可以根据上文S221a中所述的第一参考信息，筛选出部分卫星的第二信号测量信息，并向位置管理功能设备发送该部分卫星的第二信号测量信息。具体筛选的过程可以参考上文S221a中的相关描述，这里不再赘述。

在一些实施例中，若第一信息包括多个类型或多个卫星的修正量的情况下，接入网设备可以根据第二参数信息，从第一信息中筛选出合适类型的修正量，并将合适类型的修正量作为第一信息的内容。
在一些实施例中，无论位置管理功能设备根据第二参数信息，是否从第一信息中筛选出相应的修正量，位置管理功能设备都可以通过多个接入网设备发送的多个第三信号测量信息，自己重新确定修正量作为第一信息的内容，并发送给接入网设备。
本申请实施例对位置管理功能设备接收的多个接入网设备中每个接入网设备发送的第三信号测量信息的个数不作限定。
本申请实施例对多个接入网设备中每个接入网设备发送的第三信号测量信息的个数是否相同也不作限定。
需要说明的是，位置管理功能设备可以通过多个接入网设备发送的多个第三信号测量信息，自己重新修正量作为第一信息的内容，可以理解为，位置管理功能设备通过多个接入网设备发送的多个第三信号测量信息中，针对同一颗卫星的第三信号测量信息，自己重新确定修正量作为第一信息的内容。
例如，若位置管理功能设备1分别接收到接入网设备1发送的100个第三信号测量信息和接入网设备2发送的80个第二信号测量信息。其中，100个第三信号测量信息是接入网设备1对卫星编号分别为1，2，……，60，110，111……150的卫星信号进行测量得到。80个第二信号测量信息是接入网设备2对卫星编号分别为1，2，……，80的卫星信号进行测量得到。此时，位置管理功能设备可以通过接入网设备1和接入网设备2针对同一卫星的卫星信号进行测量得到的信号测量信息，即接入网设备1对卫星编号分别为1， 2，……，60的卫星信号进行测量得到的第三信号测量信息和接入网设备2对卫星编号分别为1，2，……，60的卫星信号进行测量得到的第二信号测量信息，重新确定修正量作为第一信息的内容。
示例性地，位置管理功能设备设置基于例如状态空间表达式(state space representation，SSR)或精确点定位(precise point positioning，PPP)，根据多个接入网设备发送的多个第二信号测量信息和多个接入网设备的绝对位置得到第一信息。该S322c的过程S321b的过程类似，关于S322c的未描述可以参考S321b中的相关描述，这里不再赘述。
在一个示例中，位置管理功能设备本身记录有接入网设备的绝对位置。即在322c中，位置管理功能设备从位置管理功能设备获取接入网设备的绝对位置。
在另一个示例中，位置管理功能设备本身未记录接入网设备的绝对位置，接入网设备记录有接入网设备的绝对位置，此时，位置管理功能设备可以从接入网设备获取接入网设备的绝对位置。具体的，接入网设备向位置管理功能设备发送接入网设备的绝对位置。相应地，位置管理功能设备接收来自接入网设备发送的接入网设备的绝对位置。
可选地，在该示例中，位置管理功能设备可以向接入网设备发送第二位置请求信息，该第二位置请求信息用于请求接入网设备的绝对位置。接入网设备在接收到第二位置请求信息后，向位置管理功能设备发送接入网设备的绝对位置。
S323c，接入网设备向终端设备发送第一信息。相应地，终端设备接收来自接入网设备发送的第一信息。
关于S323c的相关描述可以参见上文S323a的相关描述，这里不再赘述。

可选地，在另一个示例中，接入网设备可以作为被动方，被动执行S321c至S323c。在该示例中，可选地，如图9所示，在S321c之前，S320还包括：
S324c，位置管理功能设备向接入网设备发送第六消息。其中，第六消息用于请求向位置管理功能设备发送第二信号测量信息。相应地，接入网设备接收来自位置管理功能设备的第六消息。

示例性地，位置管理功能设备将第六消息传递给接入网设备的方式可以和上文S225a中位置管理功能设备将第一消息传递给接入网设备的方式类似，这里不再赘述。
可选地，在一些实施例中，S324c中涉及的接入网设备可以是位置管理功能设备确定的。
关于位置管理功能设备如何确定S324c中涉及的接入网设备的描述可以参考上文关于位置管理功能设备如何确定S225a中涉及的接入网设备的相关描述，这里不再赘述。
可选地，在一些实施例中，在S324c之前，还可以执行S226a。关于S226a的相关描述参考上文中的描述，这里不再赘述。
可选地，在一些实施例中，第六消息包括上报第二信号测量信息的次数和/或周期。这样可以将最新的卫星数据发送给位置管理功能设备。进而，位置管理功能设备根据最新的卫星数据确定修正量并将修正量传输给终端设备。在终端设备后续对卫星进行测量的过程中，根据该修正量对终端设备的测量位置进行修正，进而能够辅助终端设备的精准定位。
在该实施例中，S321c具体包括：接入网设备根据向位置管理功能设备发送第二信号测量信息的次数和/或周期，向位置管理功能设备发送第二信号测量信息。
在该实施例中，S322c具体包括：位置管理功能设备根据向位置管理功能设备发送第二信号测量信息的次数和/或周期，向接入网设备发送第一信息。
在该实施例中，S323c具体包括：接入网设备根据上报第二信号测量信息的次数和/或周期，向位置管理功能设备发送第一信息。
接入网设备周期性地根据第二信号测量信息获取卫星的修正量，并周期性地将修正量发给位置管理功能设备。这样，接入网设备可以将最新的修正量上报给位置管理功能设备。进一步地，位置管理功能设备周期性地对修正量进行处理，并周期性地将处理后的修正量发给接入网设备。进而接入网设备可以周期性地将修正量发送给终端设备，即接入网设备可以将最新的修正量发送给终端设备，在终端设备后续对卫星进行测量的过程中，根据该修正量对终端设备的测量位置进行修正，进而能够辅助终端设备的精准定位。
可选地，在一些实施例中，方法300还包括：

此外，在方法200和方法300结合实施的方案中，需要说明以下几点：
1、方法200和方法300中重复的步骤可以只执行一次。
例如，S210和S310可执行一次。具体地，接入网设备对卫星的卫星信号进行测量，获取信号测量信息，该信号测量信息包括第一信号测量信息的内容和第二信号测量信息的内容。
2、方法200和方法300中同一执行主体执行的某些步骤可以合并，即通过一个步骤实现多个步骤。
例如，接入网设备可以将方法200的S220中所述的第一参数信息和方法300的S320中所述的第一信息携带在一个消息中发送给终端设备或位置管理功能设备。
又例如，在方法200的S220包括S225a以及方法300的S320包括S327a的情况下，第一消息和第四消息可以通过一个消息同时实现第一消息的功能和第四消息的功能。
应理解，上述列举仅为示例，不对本申请构成限制。本申请实施例还可以包括其他可以通过一个步骤实现多个步骤，这里不再一一列举。
可选地，在一些实施例中，如上文图2至图9所述的实施例，接入网设备还可以用另一终端设备替代。这样，在该实施例中，另一终端设备本身可以获取卫星信号，这样，另一终端设备可以自己根据卫星信号确定卫星的参数信息，并将参数信息传递给终端设备或位置管理功能设备。或者，另一终端设备将卫星信号传递给位置管理功能设备，位置管理功能设备可以根据卫星信号确定卫星的参数信息，并将参数传递给另一终端设备。进而无需在网络中部署第三方服务器，可以沿用3GPP相关标准，终端设备或位置管理功能设备即可获取到卫星的参数信息，降低了网络的复杂度和成本。此外，对于终端设备而言，无需额外激活并维护PDU Session会话相关数据，且能够快速搜索捕获另一终端设备附近上空卫星广播信号并完成定位，降低了终端设备的成本以及耗电量。

例如，网络侧可以签约授权每个终端设备的能力信息。这样，位置管理功能设备可以通过接入和移动性管理功能设备查找到具备GNSS基准站能力的终端设备，进而位置管理功能设备可以将该具备GNSS基准站能力的终端设备作为S225a、S224b、S224c、S325a、S324b、或S324c中涉及的另一终端设备。
又例如，每个终端设备可以通过接入和移动性管理功能设备将其自身能力信息告知位置管理功能设备。这样，位置管理功能设备可以通过接入和移动性管理功能设备查找到具备GNSS基准站能力的终端设备，进而位置管理功能设备可以将该具备GNSS基准站能力的终端设备作为S225a、S224b、S224c、S325a、S324b、或S324c中涉及的另一终端设备。
