Description

用于切换的资源配置的方法、网络接入点以及移动台
本申请要求于2016年02月05日提交中国专利局、申请号为PCT/CN2016/073675、发明名称为“用于切换的资源配置的方法、网络接入点以及移动台”的PCT专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明实施例涉及通信领域，并且更具体地，涉及一种用于切换的资源配置的方法、网络接入点以及移动台。
背景技术
未来的网络系统会将应用领域扩展到车与任何设备间的通信(Vehicle to X，V2X)，包括车辆-车辆(Vehicle to Vehicle，V2V)通信，车辆-道路设施(Vehicle to Infrastructure，V2I)通信，车辆-行人(Vehicle to Pedestrian，V2P)通信，行人-车辆(Pedestrian to Vehicle，P2V)通信等。
V2X通信能够有效地提升交通通行效率，避免交通事故，降低行车风险，据研究表明，V2V通信可以解决美国国内大约82％的无人员伤亡碰撞以及大约40％交通十字路口的碰撞。
在V2X通信过程中，车辆需要始终与网络保持连接，以便有效地接收网络侧的信息，保证资源分配的可靠性，提高数据传输的效率。但是在一些场景，如网络无覆盖时，车辆一般按照预先配置的资源进行通信，这样无法保证大量连接的车辆进行有序的信息交互，很大程度上降低了无线网络的资源使用效率。因此未来V2X通信在绝大多数范围内将依托于车与网通信而存在，所以需要保证车与网之间的连接保持顺畅，从而保障网络对于车辆的有序调度及资源分配。
在此过程中，由于车辆不断移动，且在某些场景中速度较快，如何保证车辆顺利地在不同网络接入点之间切换成功将是亟待解决的关键问题。
尽管在传统蜂窝网络中存在保证切换的机制，然而现有切换流程中，存在较大的传输中断时延，并且无法有效克服针对快速行驶移动台的信道瞬变问题等。

图1是根据本发明实施例的移动台的切换过程的示意图。如图1所示，包括第一网络接入点100、第二网络接入点200和移动台300。
其中，第一网络接入点100与第二网络接入点200可以通过蜂窝链路进行通信，例如，通过第一网络接入点100与第二网络接入点200之间的通信接口进行通信，这里的通信接口可以是X2接口。
移动台300可能处于快速移动的状态，例如，移动台300初始处于第一网络接入点100的网络覆盖范围内，能够与第一网络接入点100进行直接通信。后续由于移动台300的快速移动，逐渐进入到第二网络接入点200的网络覆盖范围内。在该过程中，移动台300需要切换相应的传输资源，这样可能会导致较大的传输时延。
本发明实施例利用移动台移动具有可预测性这一特点，预先在网络接入点间协调切换资源，以便于移动台在切换的过程中使用该切换资源，从而能够减少切换中断时间。
应理解，本发明实施例中的情况和方式等的划分仅是为了描述的方便，不应构成特别的限定，各种情况和方式中的特征在不矛盾的情况下可以相结合。
图2是根据本发明实施例用于切换的资源配置的方法的一例的示意性流程图。图2所示的方法由第一网络接入点执行，包括：
S110，第一网络接入点确定与第二网络接入点之间的切换资源配置信息。
这里，切换资源配置信息可以包括以下的至少一种：物理时频资源块的位置信息、调制编码配置信息、参考信号的配置信息、天线配置信息。
切换资源配置信息也可以包括时频资源配置信息、传输带宽等等，这里不再一一罗列。
可选地，该切换资源配置信息包括服务网络接入点由第一网络接入点切换至第二网络接入点使用的切换资源的配置信息；和/或该切换资源配置信息包括服务网络接入点由第一网络接入点切换至第一网络接入点和第二网络 接入点使用的切换资源的配置信息；和/或该切换资源配置信息包括第一网络接入点的切换资源的配置信息。
可理解，在第一网络接入点周围会部署至少一个其他的网络接入点，第一网络接入点与至少一个其他的网络接入点直接可以通过通信接口(如X2接口)进行通信。
作为第一种情形，如果第一网络接入点周围只有一个其他的网络接入点，即第二网络接入点。那么，在S110中，第一网络接入点只需确定与第二网络接入点之间的切换资源配置信息。
可选地，第一网络接入点可以通过通信接口，与所述第二网络接入点进行协调，以确定所述切换资源配置信息。
其中，第一网络接入点与第二网络接入点同步，或者，第一网络接入点与第二网络接入点之间具有固定的第一定时偏移(offset)值。
第一网络接入点可以与第二网络接入点进行资源协调，通过协商的方式确定切换资源池。例如，可以确定第一切换资源池和第二切换资源池。其中，第一切换资源池可以由第一网络接入点随后发送至移动台，以使得移动台从第一网络接入点切换至第二网络接入点的过程中，使用第一切换资源池中的切换资源。其中，第二切换资源池可以由第二网络接入点随后发送至移动台，以使得移动台从第二网络接入点切换至第一网络接入点的过程中，使用第二切换资源池中的切换资源。
这样，从第一网络接入点切换至第二网络接入点的移动台所使用的切换资源，与从第二网络接入点切换至第一网络接入点的移动台所使用的切换资源尽可能地不相同，能够避免切换过程中不同的移动台之间的资源冲突，减少资源竞争，更能够保证切换过程中的移动台的数据传输的效率。
作为第二种情形，如果第一网络接入点周围有多个(即至少两个)其他的网络接入点(包括第二网络接入点)。那么，S110中，第一网络接入点可以确定与多个网络接入点之间的切换资源配置信息。其中，多个网络接入点包括第二网络接入点。
可选地，第一网络接入点可以通过相互间的通信接口，与多个网络接入点进行协调，以确定相应的切换资源配置信息。
作为一个实施例，第一网络接入点可以确定多个网络接入点共同的切换资源配置信息。此时，第一网络接入点确定一组切换资源配置信息。
作为另一个实施例，第一网络接入点可以分别确定与每个网络接入点之间的切换资源配置信息。此时，第一网络接入点确定与多个网络接入点一一对应的多组切换资源配置信息。
S120，第一网络接入点将所述切换资源配置信息发送至移动台。

其中，控制信令可以为物理层控制信令，例如为物理下行控制信道(Physical Downlink Control Channel，PDCCH)。
其中，第一网络接入点与移动台同步，或者，第一网络接入点与移动台之间具有固定的第二定时偏移值。
可选地，作为一个实施例，可以在移动台接入第一网络接入点的网络时，将切换资源配置信息发送至移动台。例如，可以在移动台与第一网络接入点进行随机接入的过程中，将切换资源配置信息发送至移动台。
可选地，作为另一个实施例，可以在移动台接入第一网络接入点的网络后，将切换资源配置信息发送至移动台。例如，可以在移动台与第一网络接入点随机接入的过程完成之后，将切换资源配置信息发送至移动台。
可选地，作为另一个实施例，可以在确定移动台即将从第一网络接入点切换至第二网络接入点时，将切换资源配置信息发送至移动台。
相应地，可理解，在S120之前，第一网络接入点可以判断移动台是否即将切换，例如，判断移动台是否即将从第一网络接入点切换至第二网络接入点。
举例来说，可以根据移动台反馈的测量信号的强度判断移动台是否即将切换。或者，可以根据移动台的移动轨迹判断移动台是否即将切换。或者，可以根据移动台的移动轨迹和移动速度判断移动台是否即将切换。
应注意，如果在S110中确定与多个网络接入点一一对应的多组切换资源配置信息，那么，在S120中，第一网络接入点发送至移动台的切换资源配置信息时，还应包括对应的网络接入点的标识信息。
可选地，第一网络接入点还可以向移动台发送第二指示信息，该第二指示信息包括以下至少一种：第一网络接入点与第二网络接入点之间的同步信息、所述移动台的速度信息、所述移动台的运动轨迹信息。这里的同步信息 包括上行同步信息和下行同步信息。这样，移动台在获取上行同步信息、下行同步信息、速度信息、运动轨迹信息等之后，可以进一步确定第二网络接入点的上行同步信息。
其中，第一网络接入点与第二网络接入点之间的同步信息可以包括第一定时偏移值。这样，移动台可以基于该同步信息中的第一定时偏移值以及移动台与第一网络接入点之间的同步关系，获取第二网络接入点的同步信息。
S130，所述第一网络接入点接收所述移动台向第一网络接入点发送的切换指示信息。
这里，所述切换指示信息用于指示所述移动台即将进行切换。可选地，所述切换指示信息是通过物理层控制信令的预留信息比特进行指示的；或所述切换指示信息通过介质访问控制MAC层信令进行指示的；或所述切换指示信息通过无线资源控制RRC信令进行指示的。

例如，移动台当前与第一网络接入点通信，该切换指示信息可以用于指示该移动台即将与其他网络接入点进行通信。
1b、移动台需要从当前网络接入点切换至当前网络接入点和其他网络接入点。
例如，移动台当前与第一网络接入点通信，该切换指示信息可以用于指示该移动台即将与第一网络接入点和其他网络接入点进行通信。
2、移动台即将进行网络接入点资源的切换。
例如，假设移动台当前使用第一网络接入点的第一资源，该切换指示信息用于指示该移动台即将使用第一网络接入点的其他资源。
本发明实施例中，利用移动台的移动具有可预测的方向性这一特点，通过引入切换资源配置信息的概念，预先在网络接入点间协调切换资源，当移动台需要切换时，便可以使用该切换资源资源配置信息进行切换，从而减少切换中断时间。进一步地，移动台可以通过切换指示信息告知第一网络接入 点该移动台即将进行切换，该方式灵活性较高，移动台可以在有需要的时候进行切换，能够提高切换效率，可以缩短切换中断时间，同时该方法可以提高用户体验。
可选地，在本发明实施例中，该第一网络接入点接收到该切换指示信息之后可以向该移动台发送第一指示信息。该第一指示信息可以用于指示所述移动台使用所述切换资源配置信息所指示的配置(其中，该切换资源配置信息可以包括切换资源和相关参数)与所述第一网络接入点和/或所述第二网络接入点进行通信。
需要说明是，在本发明实施例中，切换指示信息可以包括上述多种情况的切换，相应地，该第一指示信息可以用于响应该切换指示信息。以下，以切换指示信息即将进行网络接入点的切换为例，对本发明实施例进行详细描述。
在本发明实施例中，假设移动台将要进行网络接入点的切换。其中，该切换的目标网络接入点可以是移动台确定的也可以是第一网络接入点确定的。
(1)移动台确定移动台即将切换至第二网络接入点(即目标网络接入点)。
可选地，该第一网络接入点还可以接收移动台发送的第二网络接入点的标识信息。该第一网络接入点可以根据该标识信息以及该切换指示信息，确定该移动台即将切换至该第二网络接入点。
其中，该标识信息和该切换指示信息可以承载于同一条消息中，也可以承载于两条消息中，本发明实施例在此不作限定。
可选地，若第一网络接入点还接收到该标识信息，上文中的第一指示信息可以为ACK反馈信息。
第一网络接入点获取该移动台即将切换至第二网络接入点之后可以进行相关操作。例如，可以通知第二网络接入点准备接入该移动台等操作。
(2)第一网络接入点确定移动台即将切换至第二网络接入点。
具体地，该第一网络接入点接收到该切换指示信息之后，该第一网络设备获知该移动台有切换网络接入点的需求，该第一网络设备可以确定该目标接入点。
例如，根据所述移动台的移动轨迹确定所述移动台即将从所述第一网络 接入点切换至所述第二网络接入点。
又例如，根据所述移动台反馈的测量信号的强度确定所述移动台即将从所述第一网络接入点切换至所述第二网络接入点。
再例如，根据所述移动台的移动轨迹和移动速度确定所述移动台即将从所述第一网络接入点切换至所述第二网络接入点。
该第一网络接入点可以确定该移动台的目标网络接入点之后，可以通过第一指示信息将目标接入点告知移动台。换句话说，当确定所述移动台即将从所述第一网络接入点切换至所述第二网络接入点时，该第一网络接入点可以向所述移动台发送所述第一指示信息。
需要说明的是，根据本发明实施例的方法，第一网络接入点可以预先将切换资源配置信息发送至移动台，以便于移动台可以在需要进行切换的时候可以根据切换资源配置信息所指示的配置进行切换，能够降低切换中断时间。进一步地，该移动台是否即将进行切换可以由第一网络接入点确定也可以由移动台确定。相应地，该目标网络接入点可以由第一网络接入点确定也可以由移动台确定。该方案的灵活性高，有利于移动台进行切换。
可选地，第一指示信息可以是通过物理层控制信令的预留信息比特进行指示的；或者，第一指示信息是通过分配的新的无线网络临时标识(Radio Network Temporary Identifier，RNTI)进行指示的；或者，第一指示信息是通过新的物理层控制信令格式进行指示的。
应注意，本发明实施例中，物理层控制信令的预留信息比特可以是指：现有协议所定义的物理层控制信令的格式中，未被使用的没有具体的定义的预留(reserved)字段或预留比特。
应注意，本发明实施例中，新的物理层控制信令格式与现有协议中所定义的物理层控制信令格式不同，或者也可以理解为是未来协议中重新定义的物理层控制信令格式。
应注意，本发明实施例中，分配的新的RNTI是在现有的RNTI之外重新分配的，该新的RNTI可以专门用于表示第一指示信息。
可选地，移动台可以在接收到第一指示信息之后，使用S120所接收到的切换资源配置信息所指示的切换资源，与第一网络接入点和/或第二网络接入点进行通信。
可选地，可以在确定移动台即将从第一网络接入点切换至第二网络接入 点时，将第一指示信息发送至移动台。
应注意，如果在S110中确定与多个网络接入点一一对应的多组切换资源配置信息，在S120中将多组切换资源配置信息以及对应的网络接入点的标识信息发送至移动台。那么，在S130中，第一指示信息可以包括网络接入点的标识信息。
例如，第一指示信息包括第二网络接入点的标识信息，那么在S130中移动台接收到第一指示信息之后，可以根据第一指示信息所包括的第二网络接入点的标识信息，确定与该标识信息对应的切换资源配置信息，并使用该切换资源配置信息所指示的切换资源，进行后续的通信。
可选地，在S130之后，第一网络接入点可以接收移动台使用该切换资源发送的上行数据。
例如，若移动台使用切换资源发送多个相同的上行数据包，那么，第一网络接入点可以接收该多个相同的上行数据包，确定其中的一个上行数据包为上行接收数据包，并获取该上行接收数据包中的所述上行数据。
其中，第一网络接入点可以与至少一个其他的网络接入点进行协调，以接收移动台使用该切换资源发送的上行数据。这里的至少一个其他的网络接入点可以包括第二网络接入点。也就是说，第一网络接入点可以与第二网络接入点进行协调，并接收移动台使用该切换资源发送的上行数据。
应注意，第一网络接入点与其他网络接入点进行协调接收时，每个网络接入点接收数据包时所使用的物理资源的位置和配置完全相同；或者，每个网络接入点接收数据包时所使用的物理资源的位置和配置完全错开。并且，随后从接收到的数据包中选择其中的一个数据包作为接收数据包。
