Description

用于数据传输的方法、终端设备和网络侧设备 技术领域
本申请实施例涉及通信领域，并且更具体地，涉及一种用于数据传输的方法、终端设备和网络侧设备。
背景技术
在高速光网络系统中，对多个信道的光信号进行复用并利用一条光纤进行传输的光复用传输技术是必不可少的，其中，相干码分多址(Code Division Multiple Access，简称为“CDMA”)是光通信中多点到点系统的重要实现方式。在基于相干CDMA的网络架构中，各个业务站点的自启动过程是通信系统中业务站点与整个网络进行通信的首要步骤。当业务站点需要接入网络进行通信时，将发起随机接入过程，然而由于在相同的波长资源下可利用的扩频码是有限的，当多个业务站点同时接入的时候可能被分配相同的扩频码，从而发生冲突。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。
本申请结合终端设备和网络侧设备描述了各个实施例。终端设备也可以指用户设备、用户单元、用户站、用户终端、终端、用户代理或用户装置。网络侧设备也可以指基站机房或光线路终端。
图1示出了本申请实施例的一种应用场景100的示意性框架图。如图1 所示，终端设备11至13通过光纤31与网络侧设备21进行通信，且该通信网络为相干CDMA网络。在终端设备11与终端设备12同时接入网络时，可能会被分配相同的扩频码，从而使得终端设备11和终端设备12均无法正常接入网络。
图2是根据本申请实施例的用于数据传输的方法200的示意性交互图。该方法200可以应用于图1所示的场景，当然，也可以应用于其他光通信场景，本申请实施例并不对此进行特别限定，例如，该网络还可以是非相干CDMA网络。
在201中，终端设备从至少一个码字中选取第一码字。
可选地，在本申请实施例中，该终端设备可以接收网络侧设备广播的用于指示该至少一个码字的指示信息。
例如，该终端设备可以接收该网络侧设备广播的包括该至少一个码字的码字集合。
可选地，该至少一个码字为全部码字中未被其它终端设备用于数据传输的码字。
例如，终端设备和网络侧设备均已知全部码字包括码字1、码字2和码字3，该网络侧设备确定当前还未用于数据传输的码字包括码字1和码字2，则该网络侧设备所广播的指示信息可以是{1,2}，用于指示该终端设备码字1和码字2是可用码字；或者，该网络侧设备所广播的指示信息可以是{1,1,0}，其中，“1”用于指示该码字可用，“0”用于指示该码字不可用。
可选地，在本申请实施例中，该终端设备还可以接收其它终端设备发送给该终端设备的用于指示该至少一个码字的指示信息。
可选地，在该网络侧设备确定不存在可用的码字时，该网络侧设备可以广播用于指示不存在可用码字的指示信息。
例如，该网络侧设备可以广播一个空集或者“0”，以用于指示不存在可用码字。
在202中，该终端设备利用该第一码字对第一标识进行编码。
可选地，该第一标识可以是该终端设备随机生成的。
在203中，该终端设备向该网络侧设备发送该编码后的第一标识。
在204中，该网络侧设备接收第二标识。
其中，该第一标识为该终端设备所发送的标识，该第二标识为该网络侧设备所接收的经过传输之后的该第一标识。
具体地，在该终端设备选取该第一码字的情况下，可能还有其它终端设备选择该第一码字，此时，该终端设备向该网络侧设备发送利用该第一码字进行编码的第一标识时，会受到其它终端设备利用该第一码字进行编码的标识的影响，即出现码字冲突，则该第二标识与该终端设备所发送的第一标识不同；在只有该终端设备选取的该第一码字的情况下，该终端设备向该网络侧设备发送利用该第一码字进行编码的第一标识时不会受到影响，则该第二标识和该第一标识相同。
在205中，该网络侧设备广播该第二标识。
此时，由于该终端设备还没有接入该网络侧设备，因此该网络侧设备不能够获知发送该第二标识的终端设备，因此该网络侧设备需要将该第二标识进行广播。
在206中，该终端设备接收该第二标识。
在207中，该终端设备利用该第一码字对该第二标识进行解码。
具体地，在还有其它终端设备选择该第一码字的情况下，解码后的该第二标识和该第一码字不相同；而在只有该终端设备选取的该第一码字的情况下，该终端设备向该网络侧设备发送利用该第一码字进行编码的第一标识时不会受到影响，则该第二标识和该第一标识相同。
在208中，在解码后的该第二标识和该第一标识相同时，该终端设备利用该第一码字对后续数据进行编码。
因此，在只有该终端设备选取该第一码字的情况下，该终端设备可以使用该第一码字进行后续的数据传输。
在209中，该终端设备向该网络侧设备发送编码后的后续数据。
在一种实现方式中，该终端设备可以获取该第一码字所对应的色散信息和/或频偏信息；该终端设备可以利用该色散信息和/或频偏信息对待发送给网络侧设备的第一数据进行补偿；在进行补偿之后，该终端设备可以利用该第一码字对补偿后的该第一数据进行编码；该终端设备向该网络侧设备发送该补偿和编码后的第一数据。
此时，该终端设备能够根据该色散信息和/或频偏信息对待发送的数据进 行补偿，进一步地提升传输性能。
可选地，该终端设备还可以先利用该第一码字对待发送的第一数据进行编码，再利用该第一码字所对应的色散信息和/或频偏信息编码后的该第一数据进行补偿。

可选地，该网络侧设备已知该终端设备所发送的第一前导数据，在该编码后的第一前导数据在传输过程中发生变化时，该网络侧设备可以根据已知的第一前导数据与该传输后的第一前导数据，确定与该第一码字对应的色散信息和/或频偏信息。
可选地，该网络侧设备在接收到该第一前导数据时，可以利用所有可用的码字对该第一前导数据进行解码，能够成功解码的码字即为该终端设备对该第一前导数据进行编码时所使用的第一码字。
可选地，该网络侧设备在确定该第一码字所对应的色散信息和/或频偏信息之后，可以将该色散信息和/或频偏信息发送给其它终端设备，再由其它终端设备转发给该终端设备，因此，该终端设备可以接收其它终端设备发送的该色散信息和/或频偏信息。
可选地，该网络侧设备还可以将用于数据传输的全部码字中每个码字所对应的色散信息和/或频偏信息进行广播；该终端设备在接收到广播消息之后，从中确定与该第一码字所对应的该色散信息和/或频偏信息。
可选地，该网络侧设备在确定不需要进行补偿时，可以向该终端设备发送用于通知该网络侧设备不需要进行补偿的通知消息；该终端设备在接收到该通知消息之后，不会对第一数据进行补偿。
在另一种实现方式中，该终端设备可以获取该第一码字所对应的同步信息；该终端设备可以利用该第一码字对第一数据进行编码；该终端设备可以在向该网络侧设备发送该编码后的该第一数据之前进行同步；在进行同步之后，该终端设备向该网络侧设备发送该编码后的第一数据。
可选地，在解码后的该第二标识和该第一标识相同时，该终端设备可以利用该第一码字对待发送给该网络侧设备的第二前导数据进行编码；该终端设备将编码后的该第二前导数据发送给该网络侧设备；该网络侧设备利用该第一码字对该经过传输的编码后的第二前导数据进行解码，获得传输后的第二前导数据；该网络侧设备根据该传输后的第二前导数据，确定与该第一码字对应的同步信息；该网络侧设备利用该第一码字对该同步信息进行编码，并发送给该终端设备；该终端设备利用第一码字对编码后的该同步信息进行解码，从而获取该同步信息。
可选地，该网络侧设备已知该终端设备所发送的第二前导数据，在该编码后的第二前导数据在传输过程中发生变化时，该网络侧设备可以根据已知的第二前导数据与该传输后的第二前导数据，确定与该第一码字对应的色散信息和/或频偏信息。
可选地，该网络侧设备在确定该第一码字所对应的同步信息之后，可以将该同步信息发送给其它终端设备，再由其它终端设备转发给该终端设备。
可选地，该网络侧设备还可以将用于数据传输的全部码字中每个码字所对应的同步信息进行广播；该终端设备在接收到广播消息之后，从中确定与该第一码字所对应的该同步信息。
可选地，该同步信息中包括该第一码字所对应的需要偏移的码字长度，该终端设备通过偏移该码字长度来实现同步。
可选地，该网络侧设备在确定需要进行异步通信时，可以向该终端设备发送用于通知该网络侧设备进行异步通信的通知消息；该终端设备在接收到该通知消息之后，直接与该网络侧设备进行异步通信。
在另一种实现方式中，该终端设备可以先获取该第一码字所对应的色散信息和/或频偏信息，并利用该色散信息和/或频偏信息对待发送给网络侧设备的第一数据进行补偿；该终端设备再获取该第一码字所对应的同步信息；该终端设备可以利用该第一码字对补偿后的该第一数据进行编码；该终端设 备在向该网络侧设备发送该经过补偿和编码后的第一数据之前可以进行同步；在进行同步之后，该终端设备向该网络侧设备发送该经过补偿和编码后的第一数据。
应理解，在本申请实施例中，该终端设备通过发送该第一前导数据获取该色散信息和/或频偏信息，以及通过发送该第二前导数据获取该同步信息，但本申请实施例不限于此，该终端设备可以向该网络侧设备发送第三前导数据，用于获取色散信息、频偏信息和同步信息中的至少一种。
可选地，在本申请实施例中，该网络侧设备在确定该终端设备所使用的码字为第一码字时，可以对未用于数据传输的至少一个码字进行更新，并广播更新之后的未用于数据传输的至少一个码字。
例如，该网络侧设备广播的未用于数据传输的码字为码字1、码字2和码字3，在该网络侧设备确定该终端设备所使用的码字为码字2时，该网络侧设备更新未用于数据传输的码字为码字1和码字3，并广播该更新后的未用于数据传输的码字。
可选地，在解码后的该第二标识和该第一标识不同时，该终端设备启动定时器，该定时器的时长为随机确定的时间；在定时器未超时的情况下，该终端设备禁止从更新后的未用于数据传输的至少一个码字中选取码字。
例如，定时器的时长为1分钟，在1分钟内该终端设备接收到该网络侧设备广播的更新后的未用于数据传输的至少一个码字时，不能够从该更新后的至少一个码字中选取码字。
因此，在本申请实施例中，该终端设备在第一标识与利用第一码字进行解码的第二标识相同，即只有该终端设备选取该第一码字时，才使用该第一码字对待发送的数据进行编码，使得终端设备在不存在码字冲突的情况下可以正常接入网络，并有效地与网络侧设备进行数据传输。
为了便于更清楚地理解本申请，以下将以图1所示的场景为例，结合图3所示的方法300以及图4所示的方法400对本申请实施例的用于数据传输的方法进行详细说明。

在304中，该终端设备11向该网络侧设备21发送该编码后的标识1。
