技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法、设备和存储介质。
背景技术
随着通信技术的发展，目前终端设备(如智能手机等)一般都具备定位功能，而且辅助定位功能也使得终端设备的定位效果更好，终端设备的辅助定位功能必须依赖于服务器为其提供辅助定位数据，而不同地区的运营商可能会选择不同的辅助定位服务器，不同的辅助定位服务器用于在终端设备和辅助定位服务器之间传递辅助定位的数据。
在实现辅助定位时，终端设备需要获取辅助定位服务器的地址，从而与辅助定位服务器交互，获取辅助定位数据。相关技术中，终端设备预先保存一个或多个辅助定位服务器的地址，若只保存一个辅助定位服务器的地址，可能该辅助定位服务器不能全球通用，若保存了多个辅助定位服务器的地址，但是该些地址可能并非都是当前网络中可用的地址，终端设备会依次尝试连接各个服务器，直到找到一个可用的服务器，这样可能影响辅助定位的效率，因此，对于本领域技术人员来说，如何获得当前网络中可用的辅助定位的服务器地址是亟需解决的技术问题。

通过上述附图，已示出本公开明确的实施例，后文中将有更详细的描述。这些附图和文字描述并不是为了通过任何方式限制本公开构思的范围，而是通过参考特定实施例为本领域技术人员说明本公开的概念。
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公开相一致的所 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、本公开的一些方面相一致的装置和方法的例子。
本申请的说明书和权利要求书及所述附图中的术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
首先对本申请所涉及的名词和应用场景进行介绍：
本申请实施例中的终端设备可以指各种形式的用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台(mobile station，MS)、远方站、远程终端、移动设备、用户终端、终端设备(terminal equipment)、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network，PLMN)中的终端设备等，本申请实施例对此并不限定。
本申请实施例中的网络设备，可以包括通信网络中(例如无线接入网或核心网)的网元。例如在4G网络的核心网中的移动管理实体MME，5G新无线(New Radio，NR)中的AMF、SMF，以及未来新的通信系统中的网络设备等。
终端设备的辅助定位功能必须依赖于服务器为其提供辅助定位数据，而不同地区的运营商可能会选择不同的辅助定位服务器，不同的辅助定位服务器用于在终端设备和辅助定位服务器之间传递辅助定位的数据。
在一些实施例中，上述辅助定位服务器为遵循安全用户平面定位(Secure User Plane Location，SUPL)协议的辅助定位服务器。用户面SUPL协议由OMA组织制定。
对网络来说，SUPL协议投入的成本小，可以基于TCP/IP网络，构建相应的SUPL服务器，因此使用较为广泛。
相关技术中，终端设备可以通过如下几种方式获取SUPL服务器地址：
SIM卡中可以保存归属运营商提供的SUPL服务器地址。但是绝大部分已发行的SIM卡中没有提供SUPL服务器地址。
终端设备在出厂时可以保存一个或多个SUPL服务器地址，但大部分终端设备中没有保存SUPL服务器地址。即便保存了SUPL服务器地址对于只保存一个地址的情况，由于法律法规的原因，很可能该地址不能全球通用(例如：supl.google.com不能在中国大陆地区使用等)。如果保存了多个地址，那么可能会依次尝试连接各个服务器，直到找到一个当前网络中可用的服务器，这样可能对整体的TTFF有影响。
其中，首次定位时间(Time To First Fix，TTFF)指的是从事件首次触发确定位置相关数据到在定位系统接口处获得位置相关数据之间经过的时间。
综上，在实际应用中，如何获得当前网络中可用且满足要求的SUPL服务器地址，是需要解决的技术问题。
本申请实施例的方法，由终端设备通过注册的网络，获得当前网络提供的辅助定位服务器的地址，即终端设备通过与当前网络的网络设备交互，获取辅助定位服务器的地址。
下面以具体的实施例对本申请的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
图1是本申请提供的通信方法一实施例的流程示意图。如图1所示，本实施例提供的方法，包括：
步骤101、终端设备向网络设备发送请求消息，请求消息包括：该终端设备支持辅助定位的能力信息。
具体的，终端设备在向辅助定位服务器请求辅助定位数据之前，终端设备向网络设备发送包括支持辅助定位的能力信息，通知网络设备其具备支持辅助定位的能力，以使网络设备向其发送辅助定位服务器的地址信息。
终端设备根据辅助定位服务器的地址信息，与辅助定位服务器交互，进行辅助定位。
在一实施例中，辅助定位遵循安全用户平面定位(Secure User Plane Location，SUPL)协议。
步骤102、终端设备接收网络设备发送的响应消息，响应消息包括：辅助定位服务器的地址信息。
具体的，网络设备在接收到终端设备的请求后，获知终端设备具备支持辅助定位的能力，向终端设备发送包括辅助定位服务器的地址信息的响应消息。
终端设备通过所注册网络获得网络侧提供的辅助定位服务器的地址，并通过连接该辅助定位服务器获得辅助定位数据。
其中，辅助定位服务器的地址信息可以包括一个或多个辅助定位服务器的地址。终端设备可以选择其中一个辅助定位服务器，连接该辅助定位服务器获得辅助定位数据。
若网络改变或接收到新的辅助定位服务器的地址，则需要重新连接其他的辅助定位服务器。
其中，网络侧提供的辅助定位服务器的地址不仅限于运营商提供，也可以是符合所在国/区域的公共服务器地址。
本实施例的方法，由终端设备通过向网络侧发起请求，获得当前网络提供的辅助定位服务器的地址，即终端设备通过与当前网络的网络设备交互，获取当前网络中可用的辅助定位服务器的地址，效率较高。
在上述实施例的基础上，终端设备通过所注册网络获得网络提供的辅助定位服务器地址的途径可以在多个信令交互流程中进行，例如在注册到无线网络过程中或注册成功之后，终端设备与网络设备交互从网络侧获得可用的辅助定位服务器地址。
在一实施例中，步骤101可以通过如下方式实现：
在网络注册过程中，所述终端设备向所述网络设备发送所述请求消息；或，
在网络注册成功后，所述终端设备向所述网络设备发送所述请求消息。
具体的，终端设备在发起注册请求时，告知网络侧该终端设备支持辅助定位，例如支持SUPL协议。
网络在收到注册请求中获知终端设备支持辅助定位，那么就可以在注册接受消息中添加网络侧希望终端设备使用的辅助定位服务器的地址。
或，终端设备在网络注册成功后，即注册到无线网络后，向网络侧发起请求，例如在PDU会话建立过程，或其他过程中发起请求。
在一实施例中，请求消息中包括指示信息，所述指示信息用于指示所述终端设备支持辅助定位，即终端设备具备支持辅助定位的能力。
在一实施例中，步骤102可以通过如下方式实现：
在网络注册过程中，所述终端设备接收网络设备发送的响应消息；或，
在网络注册成功后，所述终端设备接收网络设备发送的响应消息。
综上，可以在网络注册过程中，终端设备与网络设备交互，获取辅助定位服务器的地址，或，也可以在网络注册成功后，终端设备与网络设备交互，获取辅助定位服务器的地址，或两个过程也可以混合使用。比如，在注册发起的请求消息中告知网络侧“终端支持辅助定位”，在后续网络注册成功后，网络侧向终端设备发送辅助定位服务器的地址。
在其他实施例中，网络侧也可以在某个消息中主动将辅助定位服务器的地址发送给终端设备。
上述实施方式中，终端设备通过所注册网络获得网络提供的辅助定位服务器地址的途径可以在多个信令交互流程中进行，例如在注册到无线网络过程中或注册成功之后，终端设备与网络设备交互从网络侧获得可用的辅助定位服务器地址，灵活性较高，操作简便。
在一实施例中，辅助定位服务器的地址信息可以通过一个地址信息列表表示。
在一实施例中，所述辅助定位服务器的地址信息包括：所述地址信息的长度，至少一个所述辅助定位服务器的地址，以及各个所述辅助定位服务器的地址的长度。
具体的，网络侧发送的辅助定位服务器的地址信息中可以包括一个或多个辅助定位服务器的地址，进一步还可以包括该地址信息的总长度，例如长度为多少个字节，以及各个辅助定位服务器的地址的长度。
在一实施例中，该方法还包括以下步骤：
终端设备根据所述辅助定位服务器的地址信息，确定目标辅助定位服务器的地址信息；
终端设备根据所述目标辅助定位服务器的地址信息，向所述目标辅助定位服务器请求辅助定位数据。
具体的，若包括多个辅助定位服务器的地址，则终端设备可以按照地址信息中各个辅助定位服务器的地址的顺序，选择目标辅助定位服务器，与该目标辅助定位服务器建立连接。地址信息中包括的各个辅助定位服务器的地址可以是按照优先级顺序排列的。
或，也可以按照各个辅助定位服务器的地址的优先级，选择目标辅助定位服务器，与该目标辅助定位服务器建立连接。
进一步的，所述地址信息还包括：各个所述辅助定位服务器对应的优先级信息。
终端设备根据至少一个辅助定位服务器的地址以及各个辅助定位服务器对应的优先级信息，确定目标辅助定位服务器的地址信息。
在一实施例中，终端设备还可以依据优先顺序，选择目标辅助定位服务器的地址，例如从SIM卡中存储的辅助定位服务器的地址中选择，或从网络侧发送的辅助定位服务器的地址中选择，或从终端设备保存的辅助定位服务器的地址中选择。
例如首先从SIM卡中存储的辅助定位服务器的地址中选择，若没有则向网络侧发起请求，获取网络侧发送的辅助定位服务器的地址，从网络侧发送的辅助定位服务器的地址中选择；
若没收到网络侧发送的辅助定位服务器的地址，则从终端设备保存的辅助定位服务器的地址中选择。
上述实施方式中，终端设备从网络侧提供的辅助定位服务器地址中选择可用的辅助定位服务器地址，操作简便，效率较高。
在一实施例中，在终端设备向网络设备注册的过程中，终端设备与网络设备交互获取辅助定位服务器的地址，具体包括如下几种场景：
