Description

一种传输数据的方法、网络设备和服务器 技术领域
本申请涉及通信领域，并且更具体地，涉及一种传输数据的方法、网络设备和服务器。
背景技术
全球定位系统(Global Positioning System，GPS)是一种高精度的定位导航系统，广泛应用在各行各业中，但是受卫星钟误差，星历误差，电离层误差的影响，该方法所能达到的精度在15米左右。为满足的无人机，智能驾驶，垂直市场等应用场景，更高精度的定位是必要的。而动态实时差分(Real Time Kinematic，RTK)等技术的引入可以有效的提高定位精度，其中RTK的定位精度为厘米级。
现有RTK技术中，采用广播的方式将服务器发送的改正数或辅助数据发送给终端设备，从而实现多个终端设备使用广播的改正数或者辅助数据进行高精度定位，但是，现有的RTK技术中在辅助数据传输的过程中，具体用于传输辅助数据的传输参数并不确定，服务器、网络设备和终端设备在整个流程中的行为并不明确，导致不能有效地支撑广播辅助数据的整个流程。
发明内容
本申请提供一种传输数据的方法、网络设备和服务器，通过服务器向网络设备发送用于传输辅助数据的传输参数，有助于优化广播辅助数据的流程。
第一方面，提供了一种传输数据的方法，该方法包括：网络设备接收服务器发送的用于传输辅助数据的第一传输参数，该传输参数包括配置信息和/或优先级信息，该配置信息用于指示一个或多个系统消息中每个系统消息的传输周期和/或该一个或多个系统消息中每个系统消息所能携带的数据量的大小，该优先级信息用于指示该一个或者多个系统消息对应的数据类型的优先级；该网络设备向该服务器发送第一配置信息，该第一配置信息与该第一传输参数有关联，该第一配置信息用于指示第一系统消息的传输周期以及该第一系统消息所能携带的数据量的大小。
在一些可能的实现方式中，该配置信息可以用于指示该辅助数据中每个数据类型所在的系统消息的传输周期，以及对每个数据类型的辅助数据进行分段后每个数据分段(数据包)的数据量大小。
在一些可能的实现方式中，该服务器和该网络设备提前约定数据类型与系统消息的对应关系，则该配置信息用于指示该辅助数据中每个数据类型的传输周期以及对每个数据类型的辅助数据进行分段后每个数据分段(数据包)的数据量大小。
本申请实施例的传输方法，服务器在发送辅助数据之前和网络设备进行协商，通过服务器向网络设备发送用于传输辅助数据的配置信息和/或优先级信息，有助于网络设备更合理地配置用于传输该辅助数据的资源。
结合第一方面，在第一方面的某些可能的实现方式中，该方法还包括：该网络设备接收该服务器根据该第一配置信息发送的该辅助数据中的全部或者部分；该网络设备向终端设备发送该辅助数据中的全部或者部分。
结合第一方面，在第一方面的某些可能的实现方式中，该方法还包括：该网络设备接收该服务器发送的用于传输该辅助数据的第二传输参数，该第二传输参数包括时间参数和/或重复指示参数，该时间参数用于指示该辅助数据中每个数据类型的有效时间信息，该重复指示参数用于指示该辅助数据中需要重复发送的数据类型；其中，该网络设备向终端设备发送该辅助数据中的全部或者部分，包括：该网络设备根据该第二传输参数，向该终端设备发送该辅助数据中的全部或者部分。
具体地，时间参数具体可以包括有效时间，时延参数(Time Latency)，溢出时间和实时时间中的至少一种。有效时间指示某个数据类型的辅助数据或者某个系统消息里的辅助数据的有效时间信息；时延参数和溢出时间也具有相似的意思，即允许的时延长度和该时间溢出后，数据失效或者精度变差；实时时间表示发送该辅助数据的实时时间。

例如，服务器在该配置信息请求了至少一个系统消息中每个系统消息的传输周期和/或该至少一个系统消息中每个系统消息所能携带的数据量的大小，网络设备根据该第一消息，做出最终决定，并回复最终的配置信息。最终的配置信息可能与服务器请求的一样，也可能不一样。服务器请求的多个SIB或者多种数据类型的广播配置，网络设备可能均确定配置并相应的回复最终配置信息，也可能由于资源受限或者其他原因仅对部分SIB或者数据类型进行配置，还有可能对该对个SIB或者多种数据类型均不进行配置。
又例如，如果服务器在第一消息中请求配置数据类型1(SIB1中传输)的传输周期和TBS分别为80ms和100byte，数据类型2(在SIB2中传输)的传输周期和TBS分别为160ms和150byte，网络设备可以在第二消息中携带数据类型1或者SIB1对应的配置为80ms和100byte，数据类型2或者SIB2对应的配置为160ms和150byte；也可以只回复服务器消息数据类型1或者SIB1对应的配置为80ms和100byte，而不对数据类型2的传输进行配置。具体是否能够都配置以及，配置的数值与服务器请求配置的数值是否一样均取决于网络设备的实现。

本申请实施例的传输方法，服务器和网络设备提前进行了协商配置，服务器将配置信息以及优先级信息发送给网络设备，在网络设备资源受限的情况下，服务器可以优先传输优先级更高的辅助数据。
方法200中通过服务器向网络设备下发配置信息和/或优先级信息，在网络设备资源受限时，服务器可以优先传输优先级更高的辅助数据，下面结合方法300，介绍在服务器下发时间参数和/或重复指示参数，避免了终端设备收到辅助数据但是因为辅助数据过期 而影响定位精度。
图3示出了根据本申请实施例的传输方法300的示意性流程图，如图3所示，图3中的服务器可以对应于图1中的服务器110，图3中的网络设备可以对应与图1中的网络设备120，图3中的终端设备可以对应于图1中的终端设备130，该方法300包括：

应理解，本申请实施例中的“第二系统消息”并不对系统消息的个数做任何限定，该第二系统消息可以是一个系统消息，也可以是多个系统消息，本申请实施例对此并不做任何限定。
还应理解，该网络设备发送第二消息之前也可以没有S210的过程，例如，当该网络设备的资源发生变化时或者其他时刻，该网络设备也可以主动发送配置更新消息给该服务器，配置更新消息中携带该网络设备当前系统消息的配置信息，例如当前系统消息的传输周期以及当前系统消息所能携带数据量的大小。
例如，该服务器在该第三消息中携带该辅助数据的数据量大小为100M，该网络设备在收到该第三消息后，可以通过该辅助数据的数据量大小确定配置SIB1的传输周期和大小为100ms和100byte，并通过该第四消息将SIB1的配置信息发送给该服务器。
S330，该服务器根据该第四消息，向该网络设备发送该辅助数据以及传输参数，该传输参数包括该辅助数据中每个数据类型的时间参数和/或重复指示参数。
可选地，服务器向网络设备发送数据类型信息，所述数据类型信息还包括所述数据类型对应的第二传输参数，所述第二传输参数包括所述数据类型对应的时间参数或者重复指示参数，所述时间参数用于指示所述数据类型对应的辅助数据的有效时间信息，所述重复指示参数用于指示所述数据类型对应的辅助数据需要重复发送或者需要重复发送的次数。
具体而言，该服务器可以根据该第四消息中携带的该第二系统消息所能携带的数据量的大小，对该辅助数据进行分段，并发送给该网络设备，同时，该服务器向该网络设备指 示该辅助数据中每个数据类型的时间参数和/或重复指示参数。
时间参数具体可以包括有效时间，时延参数，溢出时间和实时时间中的至少一种。有效时间指示某个数据类型的辅助数据或者某个SIB里的辅助数据的有效时间信息；时延参数和溢出时间也具有相似的意思，即允许的时延长度和该时间溢出后，数据失效或者精度变差；实时时间表示发送该辅助数据的实时时间。时间参数可以和具体的数据类型相对应。
应理解，在本申请实施例中，该有效时间信息可以用于指示数据类型对应的辅助数据的有效时间长度或者失效时间长度。
重复指示参数用于指示某个数据类型的辅助数据或者某个SIB里的辅助数据是否可以重复发送。重复指示参数可以表示一个信元或者字段，用于表示是否需要重复发送。也可以表示为重复次数和/或重复周期等。重复次数可以用于指示将数据重复发送的次数。重复周期表示，辅助数据重复的周期。该网络设备收到该指示后，可以对相对应的数据类型的辅助数据或者某个SIB里的辅助数据进行重复发送。
应理解，若网络设备没有收到显示的优先级指示时，可以认为服务器按照请求的配置的列表的先后顺序来顺序递减或递增优先级，即第一个请求配置的信息可以是最高优先级(或者最低优先级)，并以此类推。当网络设备资源受限时，可以根据此信息进行优先配置一部分资源。
可选地，该第四消息用于指示暂时不支持广播辅助数据或者回复配置失败或者失败消息时，该第四消息还包括不支持广播的原因和/或等待的第一时间段，则服务器可以在收到该第四消息时，等待第一时间段，向该网络设备发送该辅助数据。
应理解，该时间参数和/重复指示参数可以在S330中该服务器发送该辅助数据的同时发送给该网络设备，也可以在S310该第三消息中包括该时间参数和/或重复指示参数，本申请对此并不做任何限定。
S340，该网络设备根据该传输参数，向终端设备发送该辅助数据中的全部或者部分。
具体而言，该网络设备可以将该辅助数据以分段的形式进行广播。即对于某一个数据类型的辅助数据或者系统消息的辅助数据，以分段的形式发送。
可选地，该网络设备还可以向该终端设备指示分段序号、是否最后一个包、该数据段剩余的有效时间，是否进行重复发送等信息。
例如，该网络设备从该服务器收到某个数据类型的辅助数据或某个SIB的辅助数据以及时间参数时，该网络设备可能的操作包括以下两个方面：
(1)若该时间参数可以表示为丢弃定时器(Discard Timer),即时间参数的值为定时器的最大值。当该网络设备收到该辅助数据后，可以启动该丢弃定时器：
可选地，该网络设备可以在广播每个数据分段或者数据包时，根据丢弃定时器来判断当前数据包是否有效，如果有效则广播给该终端设备。如果判断该数据包失效(如发送数据包时刻已经过了该包的有效期)，则该网络设备可以不广播该数据包(即该位置不广播)，或者广播一个失效包指示，或者广播一个失效包指示和该数据包，也可以包括有效时间。该终端设备在收到上述任意一种指示，则认为该数据包已经失效，或者使用该数据包的精度可能会变差，该终端设备可以丢弃该包，当然该终端设备也可以使用。该方法主要适用于该终端设备可以独立处理每个数据包的场景。
可选地，该网络设备还可以在收到该服务器发送的每个数据分段或者数据包时，对每 个或者最后一个或者最后几个数据包(数据分段)启动丢弃定时器，当发现有数据包出现超时，则在发送该数据包给该终端设备的时刻，该网络设备可以发空包，或者发失效包指示，或者发数据包和失效包指示，也可以携带剩余的有效时间。当该终端设备收到这些指示后可以和上一数据包处理方式一致，也可能将与该数据包相关联的之前收到的数据包全部丢弃，即如果某个数据类型的辅助数据被分为10段，第5段出现超时则该终端设备可以将之前收到的四个数据分段全部丢弃。此种方式主要是适用于该终端设备收完完整的数据包，即收齐所有的数据包一起进行处理的场景。
可选地，该网络设备可以在每个广播的数据分段或者数据包时，都包含一个有效时间，表示该包在该时间段内有效，该终端设备收到后可以进行处理，例如根据该数据包的有效时间，确定是否使用该数据包。
应理解，不同数据类型的辅助数据可以对应不同的有效时间长度(丢弃定时器时长)，也可以对应相同的有效时间长度，同一个数据类型的辅助数据的分段或者数据包的有效时间长度相同。
(2)该时间参数可以表示为时延参数，当该网络设备收到该辅助数据后，该网络设备基于实现判断每个数据包是否会失效，如果失效则不发包，或者失效包指示等类似上述方式。
具体而言，若该网络设备收到某种数据类型的辅助数据或者某个SIB的辅助数据的多个分段或者多个数据包时，若判断出，其中有数据包(数据分段)会出现失效情况，则该网络设备可以对于属于这个数据分段列表的数据包一个都不广播，或均指示失效包，或者指示失效包同时也发送数据包和/或超时时延。
应理解，这里的失效都指示数据包(数据分段)过了有效期或者时间参数具体的时间。
还应理解，S330中该服务器向该网络设备指示该辅助数据中每个数据类型的重复指示参数，该重复指示参数包括了某个数据类型的辅助数据或者某个SIB的辅助数据重复发送给该终端设备的重复周期和/或重复次数，则该网络设备向该终端设备发送某个数据类型的辅助数据时，根据该重复指示参数，将某种数据类型的辅助数据的分段或者数据包重复发送给该终端设备。
可选地，该方法300还包括：
该终端设备向该服务器发送第二请求消息，该服务器接收该终端设备发送的该第二请求消息，该第二请求消息用于请求该辅助数据中未成功接收的辅助数据；
该服务器根据该第二请求消息，向该终端设备发送该辅助数据中未成功接收的辅助数据。
具体而言，对于该服务器向该网络设备发送该辅助数据中的部分，或者，该服务器不向该网络设备发送该辅助数据时，服务器可以通过单播的形式将其余的辅助数据发送给需要该辅助数据的终端设备，可以通过终端设备在单播中请求需要的辅助数据，然后该服务器进行传输相应的辅助数据。
应理解，当该终端设备发现该网络设备广播的系统消息中辅助数据不能满足自己的定位需求时，则通过单播的形式向该服务器请求辅助数据。
S350，该终端设备根据该辅助数据，确定该终端设备的位置。
具体而言，该终端设备接收到该网络设备发送该辅助数据，根据该辅助数据，计算该 终端设备的位置信息。
还应理解，辅助数据受限于SIB的TBS，可能以不同的分段方式进行传输。在终端设备侧存在两种方式来处理辅助数据。
方式一：该终端设备计算属于一个大的数据包的所有数据段，随后破译和处理该辅助数据。
对于方式一，该终端设备需要获知最后一个数据段的指示，从而该终端设备可以获知何时开始处理之前收到的所有的数据段。
方式二：该终端设备可以独立得对每个数据段进行破译和处理。
对于方式二，该终端设备不需要在处理辅助数据时考虑辅助数据的分段信息。
本申请实施例的传输方法，服务器和网络设备提前进行了协商配置，服务器将时间参数以及重复指示参数发送给网络设备，有助于网络设备确定辅助数据是否对终端设备有效。

S420，该网络设备响应该第五消息，向该服务器发送第六消息，该第六消息包括第三系统消息的传输周期以及所述第三系统消息所能携带的数据量的大小。
应理解，若该第五消息中包括配置信息和/或优先级信息，则该网络设备可以根据该第五消息，向该服务器发送该第六消息，该第六消息包括第三系统消息的传输周期以及所述第三系统消息所能携带的数据量的大小，该一个或多个系统消息包括该第三系统消息，或者，该第六消息用于指示该网络设备不支持广播定位辅助数据，此处与S220的过程类似，为了简洁，在此不再赘述。
还应理解，若该第五消息中没有携带配置信息和/或优先级信息，则次数与S320的过 程类似，为了简洁，在此不再赘述。
还应理解，本申请实施例中的“第三系统消息”并不对系统消息的个数做任何限定，该第二系统消息可以是一个系统消息，也可以是多个系统消息，本申请实施例对此并不做任何限定。
还应理解，该网络设备发送第二消息之前也可以没有S410的过程，例如，当该网络设备的资源发生变化时或者其他时刻，该网络设备也可以主动发送配置更新消息给该服务器，配置更新消息中携带该网络设备当前系统消息的配置信息，例如当前系统消息的传输周期以及当前系统消息所能携带数据量的大小。
还应理解，若网络设备没有收到显示的优先级指示时，可以认为服务器按照请求的配置的列表的先后顺序来顺序递减或递增优先级，即第一个请求配置的信息可以是最高优先级(或者最低优先级)，并以此类推。当网络设备资源受限时，可以根据此信息进行优先配置一部分资源。
可选地，该第六消息用于指示暂时不支持广播辅助数据或者回复配置失败或者失败消息时，该第六消息还包括不支持广播的原因和/或等待的第一时间段，则服务器可以在收到该第六消息时，等待第一时间段，向该网络设备发送该辅助数据。
S430，该服务器根据该第六消息，向该网络设备发送该辅助数据中的全部或者部分。
应理解，若该第五消息包括配置信息和/或优先级信息，该网络设备根据该第五消息，向该服务器发送该第六消息，该服务器根据该第六消息中携带的第三系统消息所能携带的数据量的大小，该一个或多个系统消息包括该第三系统消息时，该服务器向该网络设备发送该辅助数据中的全部或者部分的过程与S230类似，为了简洁，在此不再赘述。
还应理解，若该第五消息不携带该配置信息和/或优先级信息，该网络设备根据该第五消息，向该服务器发送该第六消息与S330类似，为了简洁，在此不再赘述。
应理解，S410中该第五消息可以不携带该时间参数和/或优先级信息，而是在S430中该服务器向该网络设备发送该辅助数据中的全部或者部分时向该网络设备发送该时间参数和/或优先级信息。
应理解，服务器可以向网络设备周期性发送辅助数据，服务器在发送数据时可以携带该周期信息。

S450，该终端设备根据该辅助数据中的全部或者部分，确定该终端设备的位置。
具体而言，该终端设备接收到该网络设备发送该辅助数据，根据该辅助数据，计算该终端设备的位置信息；或者，当该终端设备发送收到该网络设备发送的该辅助数据的部分后，不能确定该终端设备的位置，则可以通过单播的形式向该服务器请求其余的辅助数据，在收到该服务器发送的其余的辅助数据后，计算该终端设备的位置。
本申请实施例的传输方法，服务器和网络设备提前进行了协商配置，服务器将配置信息、优先级信息、时间参数以及重复指示参数发送给网络设备，在网络设备资源受限的情 况下，服务器可以优先传输优先级更高的辅助数据，并且，有助于网络设备确定辅助数据是否对终端设备有效。
本申请实施例的传输数据的方法，在辅助数据的传输过程中存在三种情况。
第一种情况，该服务器将所有的辅助数据都发送给该网络设备进行广播。
对于第一种情况，该服务器和该网络设备可以提前协商无线资源，随后该服务器将该辅助数据进行分段后发送给该网络设备，当网络设备获取了分段的辅助数据后，该网络设备将该分段的辅助数据放在特定的SIB中周期性得发送给该终端设备。
第二种情况，该服务器只能将辅助数据中的部分发送给该网络设备进行广播。
对于第二种情况，有一部分辅助数据不能发送给该网络设备进行广播，此时，存在两种解决办法来支持其余辅助数据的传输。
解决办法一，当该终端设备仅仅从系统消息中接收到部分辅助数据后，但是这部分辅助数据并不能满足该终端设备的定位需求，此时，该终端设备可以以单播的形式直接向服务器请求其所需求的辅助数据，从而进行定位。
解决办法二，该服务器可以再一次尝试去广播该其余的辅助数据，当该网络设备指示只有一部分辅助数据可以进行广播时，该服务器可以等待一段时间后再次尝试发送其余的辅助数据。
第三种情况，该网络设备指示该服务器不支持广播辅助数据。
对于第三种情况，其解决办法与第二种情况中的相同。
以上结合图2至图4描述了本申请实施例的三种传输方法，这三种传输方法需要服务器向网络设备发送辅助数据之前，提前和该网络设备协商服务器和网络设备之间的配置等信息，以下结合图5和图6，描述服务器在获取辅助数据后直接向网络设备发送辅助数据的情况。
图5示出了根据本申请实施例的传输方法500的示意性流程图，如图5所示，图5中的服务器可以对应于图1中的服务器110，图5中的网络设备可以对应与图1中的网络设备120，图5中的终端设备可以对应于图1中的终端设备130，该方法500包括：
S510，服务器向该网络设备发送辅助数据和用于传输该辅助数据的传输参数，该网络设备接收该服务器发送的该辅助数据和用于传输该辅助数据的传输参数，该传输参数包括优先级信息、时间参数和重复指示参数中的至少一种。
具体而言，该服务器在获取终端设备用于定位的辅助数据后，将不同数据类型的辅助数据进行分段发送给该网络设备的同时，将用于传输该辅助数据的传输参数发送给网络设备，该传输参数包括优先级信息、时间参数和重复指示参数中的至少一种。
该优先级信息用于指示该辅助数据中不同数据类型的优先级。
该时间参数具体可以包括有效时间，时延参数，溢出时间和实时时间中的至少一种。有效时间指示某个数据类型的辅助数据或者某个SIB里的辅助数据的有效时间长度；时延参数和溢出时间也具有相似的意思，即允许的时延长度和该时间溢出后，数据失效或者精度变差；实时时间表示发送该辅助数据的实时时间。
该重复指示参数用于指示某个数据类型的辅助数据或者某个SIB里的辅助数据是否可以重复发送。重复指示参数可以表示一个信元或者字段，用于表示是否需要重复发送。也可以表示为重复次数和/或重复周期等。该网络设备收到该指示后，可以对相对应的数 据类型的辅助数据或者某个SIB里的辅助数据进行重复发送。
应理解，S510中服务器发送传输参数和辅助数据并没有实际的先后顺序，可以是在发辅助数据之前，将该传输参数发送给该网络设备；或者，在发辅助数据的同时，将该传输参数发送给该网络设备；或者，在发送辅助数据之后，再将该传输参数发送给该网络设备。
S520，该网络设备根据该传输参数，向该终端设备发送该辅助数据中的全部或者部分，该终端设备接收该网络设备发送的该辅助数据中的全部或者部分。
具体而言，该网络设备在收到该辅助数据和该传输参数时，根据该传输参数，向该终端设备发送该辅助数据中的全部或者部分。
