Description

一种网络失步状态处理方法、网络接入方法及装置
本申请要求在2016年3月16日提交中国专利局、申请号为201610158379.8、发明名称为“一种网络失步状态处理方法、网络接入方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及移动通信技术领域，尤其涉及一种网络失步状态处理方法、网络接入方法及装置。
背景技术
随着移动终端的增加以及终端业务种类的多样化，用户对大数据吞吐量的需求越来越大，移动通信网络势必向更大的带宽、更密集的站点部署发展。密集的网络部署使得每个基站的覆盖范围减小，而由于覆盖范围的减小，造成终端只要移动很小距离就会发生切换。
为了避免终端由于网络的密集部署带来的频繁切换产生的开销，可以采用no-cell技术。no-cell技术中，多个传输点(英文：Transmission Point，简称：TP)形成一个小区(或者称为逻辑小区，以下简称小区)。进一步，形成一个小区的多个TP可以分成多个组，每组TP由一个逻辑实体(英文：logical entity，简称：LE)进行控制，终端通过和一个逻辑实体中的一个或多个TP进行上下行协作传输。为降低频繁切换产生的开销，no cell采用以终端为中心的网络设计方法，即网络主动跟踪终端。具体的，在NCS(no cell system)系统中，当终端驻留在一个LE中时，网络侧会为终端分配一个序列号(Sequence Identification)和跟踪信道(Tracking Channel)。终端处于节能(英文：Economic，简称：ECO)态时，可以在跟踪信道上周期性的向覆盖该终端的TP发送包含该序列号的上行跟踪信号，从而使得LE能够根据TP上报的终端发送的上行跟踪信号跟踪该终端。
若终端处于ECO状态，当终端因为障碍物或干扰等因素脱网时，终端发送的上行跟踪信号无法被TP接收，同时，由于上行跟踪信号没有下行反馈，因此终端会默认自己发送的上行跟踪信号已经被TP接收。若LE在多个周期内未收到TP上报的终端发送的上行跟踪信号，则确定不能对终端进行跟踪，从而确定终端处于网络失步状态。
目前，LE确定终端处于网络失步状态后，网络侧如何处理终端还没有一个明确的解决方法。

具体实施方式
本申请实施例适用于4G(第四代移动通信系统)演进系统，如LTE(英文：Long Term Evolution，简称：长期演进)；5G(第五代移动通信系统)系统等蜂窝网络。
本申请实施例中，术语“终端”包括但不限于移动站、固定或移动用户单元、寻呼机、蜂窝电话、个人数字助理(英文：Personal Digital Assistant，简称：PDA)、计算机或任何其它类型的能在无线环境中工作的用户设备。术语“逻辑实体”包括但不限于基站、节点、基站控制器、接入点(英文：Access Point，简称：AP)、远端节点(英文：Remote Unit，简称：RU)或任何其它类型的能够在无线环境中工作的接口设备。
如图1所示，为现有技术中一种典型的no-cell通信系统架构示意图。
图1中，中央控制器101(英文：central controller，简称：CC)控制至少1个逻辑实体102；逻辑实体102控制至少1个传输点103。终端104通过和一个逻辑实体102中的一个或多个传输点103进行上下行协作传输。
图1所示的通信系统架构中，当终端104驻留在一个逻辑实体102中时，网络侧会为终端104分配一个序列号和跟踪信道。终端104可以在跟踪信道上周期性的向覆盖该终端104的传输点103发送包含该序列号的上行跟踪信号，以使网络能跟踪该终端104。终端104在一个逻辑实体102中可保持序列号不变，但切换到另一个逻辑实体102时，则切换后的另一个逻辑实体102需要重新为终端104分配序列号以及跟踪信道。
需要说明的是，图1所示的通信系统架构可以应用于4G演进系统、5G系统等蜂窝网络。
目前，LE确定终端处于网络失步状态后，则可能会向终端发送大量的寻呼(paging)信令，直到终端根据接收到的寻呼信令向网络发送反馈消息或者恢复与网络的连接。但是，网络侧向终端发送大量的寻呼信令，会导致资源消耗过大，特别是在同时有多个终端处于网络失步状态下，整个网络中会充斥着大量的寻呼信令，降低了信道容量。
基于上述描述，为了解决前面描述的问题，如图2所示，本申请实施例提供一种网络失步状态处理方法流程示意图。
图2所示的流程中，第一网络设备可以为逻辑实体，第二网络设备可以为传输点。
参见图2，该方法包括：
步骤201：第一网络设备若在确定终端处于网络失步状态后的第一时长内，未接收到处于所述第一网络设备的信号覆盖范围内的第二网络设备根据所述终端的上行跟踪信号上报的测量消息，则通知处于所述第一网络设备的信号覆盖范围内的至少一个第二网络设备向所述终端发送寻呼信令；
步骤202：若所述第一网络设备在第二时长内确定处于所述第一网络设备的信号覆盖范围内的所有第二网络设备均未接收到所述终端发送的寻呼响应、且确定所述终端仍处于网络失步状态，则将所述终端的网络状态设置为去附着状态；所述寻呼响应为所述终端接收到所述寻呼信令后发送的反馈消息。
步骤201中，对于驻留在第一网络设备信号覆盖范围的终端，若该终端在处于ECO状态时，可以按照预设规则在第一网络设备为其分配的上行跟踪信道上，向处于第一网络设备信号覆盖范围内的第二网络设备发送上行跟踪信号。其中，预设规则可以为周期性发送上行跟踪信，也可以为其它规则，在此不再赘述。
第二网络设备接收到终端发送的上行跟踪信号后，可以根据接收到的上行跟踪信号对终端进行测量、定位等操作，从而获得测量结果。第二网络设备可以将获得的测量结果通过测量消息发送给第一网络设备。第二网络设备 可以在根据所述终端的上行跟踪信号确定测量结果后，立即向第一网络设备发送测量消息；第二网络设备也可以在确定终端的位置发生变化时向第一网络设备发送测量消息；第二网络设备也可以在确定终端的位置未发生变化时，周期性的向第一网络设备发送测量消息。
需要说明的是，测量结果中可以包括终端的位置信息等信息，测量结果中具体包括的内容可以参考现有技术中的规定，在此不再赘述。相应的，第二网络设备具体如何根据终端的上行跟踪信号确定测量结果可以参考现有技术中的规定，在此不再赘述。
本申请实施例中，第一网络设备可以根据以下方式确定终端是否处于网络失步状态：
第一网络设备若在连续M个周期内未接收到第二网络设备根据所述终端的上行跟踪信号上报的所述测量消息，或者，第一网络设备若在预设时长内未接收到第二网络设备根据所述终端的上行跟踪信号上报的所述测量消息，则确定无法对终端进行跟踪，从而确定终端处于网络失步状态。其中，M可以根据实际情况确定，预设时长也可以根据实际情况确定，在此不再赘述。
本申请实施例中，第一网络设备在确定终端处于网络失步状态之后，终端可能会恢复与网络的连接。为了避免在确定终端处于网络失步状态之后，立即发送寻呼信令导致的资源消耗，第一网络设备可以等待第一时长，并确定在第一时长内仍未接收到第二网络设备根据所述终端的上行跟踪信号上报的测量消息后，通知至少一个第二网络设备发送寻呼信令。其中，第一时长可以根据实际情况确定，在此不再赘述。
具体的，第一网络设备确定所述终端处于网络失步状态之后，可以启动第一定时器，所述第一定时器的定时时长为所述第一时长。在所述第一定时器超时时，所述第一网络设备若未接收到处于所述第一网络设备的信号覆盖范围内的第二网络设备根据所述终端的上行跟踪信号上报的测量消息，则通知处于所述第一网络设备的信号覆盖范围内的至少一个第二网络设备向所述终端发送寻呼信令。在所述第一定时器超时之前，第一网络设备若接收到处 于所述第一网络设备的信号覆盖范围内的第二网络设备根据所述终端的上行跟踪信号上报的测量消息，则确定所述终端恢复了与网络的连接。
需要说明的是，寻呼信令可以是用来指示终端与任意一个第二网络设备通过随机接入过程重新接入网络。
第一网络设备在确定所述终端恢复了与网络的连接的同时，还可以关闭所述第一定时器，并通知处于所述第一网络设备的信号覆盖范围内的至少一个第二网络设备停止向所述终端发送寻呼信令。
需要说明的是，终端恢复了与网络的连接可以是指终端重新接入了第一网络设备的信号覆盖范围内的任意一个第二网络设备；或者，终端恢复了与网络的连接可以是指终端重新接入了另一个第一网络设备的信号覆盖范围内的任意一个第二网络设备。例如，第一网络设备接收到处于所述第一网络设备的信号覆盖范围内的第二网络设备根据所述终端的上行跟踪信号上报的测量消息，或者，第一网络设备确定处于所述第一网络设备的信号覆盖范围内的第二网络设备接收到所述终端发送的上行消息，则确定所述终端恢复了与网络的连接。其中，上行消息可以为所述终端处于节能态、且确定需要传输数据时发送的上行传输请求；或者，所述上行消息为所述终端处于节能态时在预设资源上发送的上行数据；或者，所述上行消息为所述终端处于连接态时发送的上行数据。
可选的，本申请实施例中，处于所述第一网络设备的信号覆盖范围内的至少一个第二网络设备中包括至少一个目标设备；所述目标设备可以为第一网络设备确定所述终端处于网络失步状态的时刻之前已接收到所述终端发送的上行跟踪信号的第二网络设备；或者，所述目标设备也可以为覆盖终端当前位置的第二网络设备。由于目标设备为确定所述终端处于网络失步状态的时刻之前接收到终端发送的上行跟踪信号的第二网络设备，因此目标设备发送的寻呼信令被终端接收到的概率更大，从而可以快速的将终端接入网络。
步骤202中，第二时长的起始时刻可以为第一网络设备通知处于所述第一网络设备的信号覆盖范围内的至少一个第二网络设备向所述终端发送寻呼 信令的时刻。第二时长的具体长度可以根据实际情况确定，在此不再赘述。
第二网络设备若接收到终端发送的寻呼响应，可以向第一网络设备发送通知消息，从而使得第一网络设备根据所述通知消息确定第二网络设备接收到了所述寻呼响应。当然，第二网络设备也可以不用发送通知消息，而是在终端根据寻呼信令接入第二网络设备后，第一网络设备接收到第二网络设备转发的终端的上行消息时，第一网络设备可以确定处于所述第一网络设备的信号覆盖范围内的至少一个第二网络设备接收到所述寻呼响应。
第一网络设备若在第二时长内确定处于所述第一网络设备的信号覆盖范围内的至少一个第二网络设备接收到所述寻呼响应，则在所述终端通过随机接入过程接入网络后将所述终端的网络状态设置为附着(attach)状态。或者，第一网络设备若在第二时长内确定所述终端恢复了与网络的连接，则将所述终端的网络状态设置为附着状态。
第一网络设备确定将终端的网络状态设置为附着状态的同时，还可以通知第二网络设备将终端的网络状态设置为附着状态。
可选的，第一网络设备还可以将第二时长划分为多个时长，并在每个时长内通知不同范围内的第二网络设备向终端发送寻呼信令。第二时长具体划分为几个时长，本申请实施例对此并不限定，下面以第一网络设备将第二时长划分为2个时长为例进行说明，第二时长划分为2个以上时长的情况可以参考下面的描述，本申请实时例对此不再赘述。
第一网络设备将第二时长划分为第三时长和第四时长。其中，所述第二时长等于所述第三时长与所述第四时长之和；第三时长在前，第四时长在后。当然，以上只是示例，第三时长和第四时长的顺序也可以相反，在此不再赘述。
第一网络设备确定所述终端处于网络失步状态之后，通知处于所述第一网络设备的信号覆盖范围中第一区域内的至少一个第二网络设备向所述终端发送寻呼信令；若所述第一网络设备在第三时长内确定所述第一区域内的所有第二网络设备均未接收到所述寻呼响应、且确定所述终端仍处于网络失步 状态，则通知处于所述第一网络设备的信号覆盖范围中第二区域内的至少一个第二网络设备向所述终端发送寻呼信令。若所述第一网络设备在第四时长内确定所述第二区域内的所有第二网络设备均未接收到所述寻呼响应、且确定所述终端仍处于网络失步状态，则将所述终端的网络状态设置为去附着(detach)状态。
若所述第一网络设备在第三时长内确定所述第一区域内的至少一个第二网络设备接收到所述寻呼响应，或者所述第一网络设备在第三时长内确定所述终端恢复了与网络的连接，则不再通过第一区域的至少一个第二网络设备向终端发送寻呼信令。相应的，若所述第一网络设备在第四时长内确定所述第二区域内的至少一个第二网络设备接收到所述寻呼响应，或者所述第一网络设备在第四时长内确定所述终端恢复了与网络的连接，则不再通过第二区域的至少一个第二网络设备向终端发送寻呼信令。
其中，所述第一区域的面积可以小于或等于所述第二区域的面积。第一区域内的至少一个第二网络设备中包括至少一个目标设备；第二区域内的至少一个第二网络设备中包括至少一个目标设备。
本申请实施例中，第三时长以及第四时长的具体长度可以根据实际情况确定，在此不再赘述。
可选的，所述第三时长为所述第一网络设备通知所述第一区域内的至少一个第二网络设备向所述终端发送寻呼信令的时刻至所述第一区域内的至少一个第二网络设备接收到所述寻呼响应的时刻之间所需的最大时长。
可选的，所述第四时长为所述第一网络设备通知所述第二区域内的至少一个第二网络设备向所述终端发送寻呼信令的时刻至所述第二区域内的至少一个第二网络设备接收到所述寻呼响应的时刻之间所需的最大时长。
本申请实施例中，可以通过设置定时器的方式实现定时。具体的，结合前面的描述，所述第一网络设备通知处于所述第一网络设备的信号覆盖范围中第一区域内的至少一个第二网络设备向所述终端发送寻呼信令时，启动第二定时器，所述第二定时器的定时时长为所述第三时长；所述第一网络设备 在所述第二定时器超时时，若确定所述第一区域内的所有第二网络设备均未接收到所述寻呼响应、且确定所述终端仍处于网络失步状态，则通知处于所述第一网络设备的信号覆盖范围中第二区域内的至少一个第二网络设备向所述终端发送寻呼信令。
所述第一网络设备在所述第二定时器超时时，启动第三定时器，所述第三定时器的定时时长为所述第四时长；所述第一网络设备在所述第三定时器超时时，若确定所述第二区域内的所有第二网络设备均未接收到所述寻呼响应、且确定所述终端仍处于网络失步状态，则将所述终端的网络状态设置为去附着状态。
结合前面的描述，如图3所示，为本申请实施例提供的一种网络失步状态处理流程示意图。
如图3所示，步骤301：终端向至少一个第二网络设备发送上行跟踪信号。
步骤302：第二网络设备在接收到上行跟踪信号后，向第一网络设备发送测量消息。
步骤303：第一网络设备确定终端处于网络失步状态后，启动第一定时器。
其中，第一网络设备若在连续M个周期内未接收到第二网络设备上报的测量消息，或者，第一网络设备若在预设时长内未接收到第二网络设备上报的测量消息，则确定终端处于网络失步状态。
步骤304：第一网络设备确定第一定时器超时时，仍未接收到测量消息，则启动第二定时器。
步骤305：第一网络设备启动第二定时器的同时，通知至少一个第二网络设备向终端发送寻呼信令。

可选的，步骤307：终端接收到寻呼信令后，向第二网络设备发送寻呼响应。
此时，第一网络设备在确定第二网络设备接收到寻呼响应之后，停止第二定时器的计时，并通知至少一个第二网络设备停止发送寻呼信令。
步骤308：第一网络设备确定第二定时器超时时，所有第二网络设备均未接收到寻呼响应，则启动第三定时器。
步骤309：第一网络设备启动第三定时器的同时，通知至少一个第二网络设备向终端发送寻呼信令。

以上描述的是第一网络设备确定终端处于网络失步状态时，第一网络设备的操作。对于终端，终端也能够确定其是否处于网络失步状态，为此，本申请实施例还提供了一种网络接入方法，用于提供一种终端在确定其处于网络失步状态后的解决方案。
具体的，如图4所示，本申请实施例提供一种网络接入方法流程示意图。
参见图4，该方法包括：
步骤401：所述终端连续N次向第一传输点发送上行消息；其中，N为自然数；
步骤402：所述终端若确定所述第一传输点针对连续N次发送的上行消息均未返回反馈消息，则确定所述终端处于网络失步状态；
步骤403：所述终端在确定所述终端处于网络失步状态后，通过随机接入过程与第二传输点建立连接。
步骤401中，终端发送的上行消息可以为上行传输请求，也可以为上行数据。
举例来说，所述上行消息可以为所述终端处于节能态、且确定需要传输数据时发送的上行传输请求。该上行传输请求可以在网络侧为所述终端分配 的跟踪信道上发送，并且发送所述上行传输请求与接收第一传输点对于该上行传输请求的反馈消息可以使用不同的时频资源，也可以使用相同的时频资源。
再举例来说，所述上行消息可以为所述终端处于节能态时在预设资源上发送的上行数据。
再举例来说，所述上行消息可以为所述终端处于连接态时发送的上行数据。
本申请实施例中，N的取值可以根据实际情况确定，在此不再赘述。例如，N可以为4。
步骤402中，第一传输点向终端返回的反馈消息可以为确认应答消息，也可以为否定应答消息。当然，还可以为其他消息，在此不再赘述。
步骤403中，所述终端通过随机接入过程建立连接的第二传输点可以为第一传输点，也可以不为第一传输点，即所述第一传输点与所述第二传输点可以为相同的传输点，所述第一传输点与所述第二传输点也可以为不相同的传输点，本申请实施例对此并不限定。
需要说明的是，本申请实施例中，终端在通过随机接入过程与第二传输点建立连接时，可以携带上次网络侧为所述终端分配的序列号，从而实现快速接入网络。
结合前面的描述，如图5所示，为本申请实施例提供的一种网络接入流程示意图。
如图5所示，步骤501：终端连续N次向第一传输点发送上行消息。
步骤502：终端若确定未接收到所述连续N次发送的上行消息的反馈消息，则确定所述终端处于网络失步状态。
步骤503：终端通过随机接入过程与第二传输点建立连接。

    若在连续M个周期内未接收到第二网络设备根据所述终端的上行跟踪信号上报的所述测量消息，或者，若在预设时长内未接收到第二网络设备根据所述终端的上行跟踪信号上报的所述测量消息，则确定所述终端处于网络失步状态。
  28. 一种网络接入装置，其特征在于，该装置包括：
    发送单元，用于连续N次向第一传输点发送上行消息；其中，N为自然数；
    处理单元，用于若确定所述第一传输点针对连续N次发送的上行消息均未返回反馈消息，则确定所述终端处于网络失步状态；在确定所述终端处于网络失步状态后，通过随机接入过程与第二传输点建立连接。
  29. 如权利要求28所述的装置，其特征在于，所述上行消息为所述终端处于节能态、且确定需要传输数据时发送的上行传输请求；或者
    所述上行消息为所述终端处于节能态时在预设资源上发送的上行数据；或者
    所述上行消息为所述终端处于连接态时发送的上行数据。
  30. 如权利要求28所述的装置，其特征在于，所述第一传输点与所述第二传输点为相同的传输点；或者
    所述第一传输点与所述第二传输点为不相同的传输点。
