网络控制器通过确定移动终端的归属无线接入设备实现对移动终端进行位置切 换，位置切换的速度由移动终端发送第二定位消息的频率决定， 因此可以通过配置第 二定位消息的发送频率来适应移动终端的移动速度。

为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现 有技术描述中所需要使用的附图作简单地介绍， 显而易见地，对于本领域普通技术人 员而言， 在不付出创造性劳动性的前提下， 还可以根据这些附图获得其他的附图。
具体实施方式 针对现有技术中存在的矿用无线通信系统中移动终端的移动性管理非常复杂、移
动终端的能耗高以及无线通信系统部署和维护成本高的问题，本发明实施例提供一种 移动性管理方法， 该方法的执行主体为网络控制器， 网络控制器可以采用该移动性管 理方法对接入的每个移动终端进行移动性管理， 具体可以通过移动终端的 ID信息来 识别移动终端，针对一个移动终端进行移动性管理的流程如图 1所示， 具体包括如下 步骤：
S11 : 接收各无线接入设备发送的第一定位消息。
移动终端可以一直处于开机状态并周期性广播第二定位消息，也可以处于休眠状 态， 然后周期性苏醒广播第二定位消息。各无线接入设备接收到第二定位消息后， 可 以向网络控制器发送携带接收第二定位消息时的接收信号强度的第一定位消息。 其 中，移动终端广播第二定位消息的广播周期可以根据实际需要进行设定， 当移动终端 高速移动时， 可以将广播周期设置的短一些， 例如设置为 0.1秒、 0.2秒等等； 当移 动终端低速移动时， 可以将广播周期设置的长一些， 例如设置为 1秒、 2秒、 5秒等 等。
由于矿井下移动终端的定位在矿井安全中至关重要，因此在本实施例适用的场景 中， 网络控制器对移动终端进行定位， 首先获取矿用无线通信系统的地图信息系统， 该地图信息系统描述了矿用无线通信系统在矿井中的部署情况，主要包括无线接入设 备在矿井下的走向、间距等， 网络控制器根据不同无线接入设备收到的同一移动终端 周期广播的第二定消息的接收信号强度以及无线接入设备在地图信息系统上的位置， 通过定位算法计算移动终端的位置， 实现对移动终端进行定位。
S12: 根据各个第一定位消息中携带的接收信号强度确定移动终端的归属无线接 入设备。
该方案中， 无线接入设备为移动终端接入网络的接入节点， 优选地在本实施例中 各个无线接入设备具体部署在 485总线上，通过 485总线连接以太网，进而与网络控 制器建立连接。移动终端周期性广播第二定位消息，各无线接入设备接收到第二定位 消息后， 向网络控制器发送携带接收第二定位消息时的接收信号强度的第一定位消 息，网路控制器根据各个第一定位消息携带的接收信号强度就确定移动终端的归属无 线接入设备， 从而在定位的同时实现对移动终端进行移动性管理， 无需额外的消息， 无需多个网元之间进行多种消息交互， 从而降低了移动终端的移动性管理的复杂程 度； 当移动终端没有通信需要时， 不参与移动性管理的消息交互， 节省了移动终端的 工作量，此时移动终端甚至可以进入休眠状态， 只需周期性苏醒发送第二定位消息即 可， 移动性管理由网络控制器来负责， 节省了移动终端的工作量和能耗； 与现有的
2G/3G/LTE无线通信系统中的小区基站相比，本实施例中的无线接入设备无需周期性 广播消息， 从而避免同频干扰， 减少了系统部署和维护成本。
具体的，上述 S12中的根据各个第一定位消息中携带的接收信号强度确定移动终 端的归属无线接入设备， 具体包括：
比较各个第一定位消息中携带的接收信号强度的大小；
将接收信号强度最大的第一定位消息对应的无线接入设备确定为移动终端的归 属无线接入设备。
移动终端的归属无线接入设备应该是距离移动终端最近的无线接入设备，而无线 接入设备与移动终端的距离远近可以通过无线接入设备接收到移动终端广播的第二 定位消息的接收信号强度来确定，接收信号强度大， 说明无线接入设备与移动终端之 间的距离小； 反之， 接收信号强度小， 说明无线接入设备与移动终端之间的距离大。 因此，网络控制器可以根据各个第一定位消息中携带的接收信号强度的大小来确定移 动终端的归属无线接入设备。
优选的方式可以是，选取接收信号强度最大的第一定位消息对应的无线接入设备 作为移动终端的归属无线接入设备。
上述方法可以应用于移动终端的位置登记过程， 在移动终端新加入时， 即新的移 动终端进入或者在当前网络控制器所覆盖范围内开机时，网络控制器确定出该移动终 端的归属无线接入设备， 完成该移动终端的位置登记， 另外， 上述方法也同样可以应 用于移动终端的位置切换过程，网络控制器通过上述方法周期性确定各移动终端的归 属无线接入设备， 从而实现对所有移动终端进行位置切换的管理。
进一步地， 为节约网络控制器的工作负担， 在上述方法中， 上述 S12中的根据各 个第一定位消息中携带的接收信号强度确定移动终端的归属无线接入设备之后，还包 括：
监测移动终端的归属无线接入设备发送的第一定位消息中携带的接收信号强度； 若确定小于设定阈值，则重新执行根据第一定位消息中携带的接收信号强度确定 移动终端的归属无线接入设备的步骤。
确定移动终端的归属无线接入设备后，还可以继续监测移动终端的归属无线接入 设备发送的第一定位消息中携带的接收信号强度，若接收信号强度小于设定阈值， 需 要重新确定移动终端的归属无线接入设备； 若接收信号强度大于设定阈值， 则保持移 动终端的归属无线接入设备不变。也就是说， 只有在移动终端距离其归属无线接入设 备较远时才会切换移动终端的归属无线接入设备，不会频繁切换移动终端的归属无线
接入设备， 从而可以节省网络控制器的工作量。
其中， 设定阈值可以根据实际需要进行设定。
可选的， 还包括：
通过移动终端的归属无线接入设备向移动终端单播消息，以使移动终端确定中继 无线接入设备。
当网络控制器需要与该移动终端进行通信时，可以通过移动终端的归属无线接入 设备向该移动终端转发单播消息，归属无线接入设备可以作为该移动终端下行通信数 据的转发点。
基于同一发明构思， 本发明实施例还提供一种移动性管理方法， 该方法的执行主 体为移动终端， 流程如图 2所示， 具体包括如下步骤：
S21 : 获取第二定位消息的广播周期。
第二定位消息的广播周期可以是预先固定设置在移动终端中的，也可以由用户设 置在移动终端设置， 还可以是网络控制器通知移动终端的。 优选地， 在本实施例中， 第二定位消息的广播周期可以由用户根据移动终端移动速度来设置调整。
S22: 根据广播周期， 周期性向各无线接入设备广播第二定位消息。
移动终端以广播周期广播第二定位消息，可以使得接收到第二定位消息的各无线 接入设备分别向网络控制器发送第一定位消息，每个第一定位消息携带对应无线接入 设备接收第二定位消息时的接收信号强度，进而使得网络控制器根据各个第一定位消 息中携带的接收信号强度确定移动终端的归属无线接收设备。
网络控制器和无线接入设备构成矿用无线通信系统的固定网络， 移动终端通过
IEEE (Institute of Electrical and Electronics Engineers, 电气和电子工程师协会） 空中 接口和矿用无线通信系统的固定网络通信。移动终端可以采用移动卡片，移动卡片为 安全型卡片， 由矿井下人员佩戴， 具有移动速度低、 电池容量低、 卡片体积小、 处理 器性能弱、 内存容量少等特点， 针对这些特点， 移动卡片的位置信息将完全由网络控 制器记录， 移动卡片的切换速度不高， 切换时主要由网络控制器和移动卡片参与， 减 少消息交互。
可选的， 上述移动性管理方法， 还包括：
接收网络控制器通过归属无线接入设备转发的单播消息；
将转发单播消息的归属无线接入设备确定为中继无线接入设备，并在需要发送单 播消息时通过中继无线接入设备发送。
移动终端接收网络控制器通过归属无线接入设备转发的单播消息，并将接收到的
单播消息的源空口地址（即转发单播消息的无线接入设备的空口地址）作为中继无线 接入设备的空口地址，中继无线接入设备是该移动终端上行通信转发节点的无线接入 设备，移动终端具体通过确定的中继无线接入设备发送上行单播消息，包括发送语音 消息、 短消息等。
在本实施例中， 移动终端的归属无线接入设备和中继无线接入设备可能为同一 个， 也可能为不同的无线接入设备， 网络控制器可以通过移动终端的归属无线接入设 备向移动终端单播消息， 移动终端接收到单播消息后， 可以更新中继无线接入设备， 无需额外的消息交互来同步转发上下行消息的无线接入设备，节省了消息量，提高了 通信效率。
可选的， 上述移动性管理方法， 还包括：
若设定时长内未接收到中继无线接入设备转发的单播消息，则向各无线接入设备 广播中继无线接入设备查询消息；
接收各无线接入设备返回的响应消息，并确定接收到各响应消息时的接收信号强 度；
将接收信号强度最大的的响应消息对应的无线接入设备确定为当前的中继无线 接入设备。
移动终端在设定时长内未接收到中继无线接入设备转发的单播消息的原因有很 多， 例如， 有可能是该中继无线接入设备已经不是该移动终端的归属无线接入设备， 因此网络控制器不会通过该归属无线接入设备向移动终端单播消息；也有可能是在设 定时长内， 网络控制器不需要向移动终端单播消息。无论是什么原因， 为了保证移动 终端与网络控制器之间的正常通信，如果移动终端在设定时长内未接收到中继无线接 入设备发送的单播消息， 移动终端可以重新确定中继无线接入设备。
具体是， 移动终端广播中继无线接入设备查询消息， 接收到中继无线接入设备查 询消息的无线接入设备会返回响应消息，移动终端确定接收各响应消息时的接收信号 强度，然后将接收信号强度最大的响应消息对应的无线接入设备确定为当前的中继无 线接入设备。
设定时长可以根据实际需要进行设定， 例如， 可以根据移动终端的移动速度来确 定， 当移动终端的移动速度较大时， 设定时长可以设置的短一些； 当移动终端的移动 速度较小时， 设定时长可以设置的长一些。设定时长可以采用定时器等等计时设备来 计时。
上述移动性管理方法不仅仅适用于矿用无线通信系统中， 同样适用于现有的
2G/3G/LTE无线通信系统以及 WiFi (Wireless Fidelity, 无线保真）通信系统中， 无线 接入设备相当于 2G/3G/LTE无线通信系统中的基站或者是 WiFi通信系统中的无线 AP (Access Point, 接入点）， 网络控制器相当于 2G/3G/LTE无线通信系统中的基站 控制器或者是 WiFi通信系统中的无线 AC (Access Controller, 接入控制器）。 基于同一发明构思， 本发明实施例还一种网络控制器， 该网路控制器的结构如图 3所示， 包括：
