一种应急通信方法和终端
本申请要求于 2012 年 9 月 26 日提交中国专利局、 申请号为 201210365146.7、 发明名称为 "一种应急通信方法和终端" 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
本申请涉及通信技术领域, 特别是涉及一种应急通信方法和终端。 发明背景
我国幅员辽阔, 地理地质、 气候条件复杂, 是世界上自然灾害最为 严重的国家之一, 自然灾害具有以下特点:
( 1 )种类多, 几乎嚢括了世界上各种类型的自然灾害。 在各类灾 害中, 尤以洪涝、 干旱和地震的危害最大。
( 2 )灾害发生的频率高、 强度大、 损失严重。 我国素有"三岁一饥、 六岁一衰、 十二岁一荒"之说。 据史料统计, 自公元前 206 ~ 1949 年的 2155年中, 共发生水灾 1029次, 较大的旱灾 1056次, 几乎水旱灾害年 年有之, 残废万人以上的灾害 10 ~ 20年出现一次。 近 40多年来, 平均 每年出现旱灾 75次, 洪涝灾害 5.8次, 台风 6.9次, 冷冻灾害 2.5次, 都远远超过世界的平均频度。 在过去的 40年中, 一般年份农作物受灾 面积为 4000万 ~ 4700万公顷, 受灾害影响人口约 2亿, 因各种自然灾 害死亡人数从千至万人, 直接经济损失 500多亿元。 1989 ~ 1992年的 4
( 3 ) 时空分布广, 灾害的地域组合明显。 我国自然灾害的空间分 布及其地域组合, 与自然和社会经济环境的区域差异具有^艮强的相关 性。 就宏观分布而言, 多发生在春、 秋两季的干旱主要分开布在西北、 黄土高原和华北; 多发生在夏季的暴雨、 洪涝灾害主要分布在广阔的东 部季风区,集中在 7大江河流域;森林火灾主要分布在东北和西南林区, 多发生在冬春干旱季节; 地震主要分布在西南、 西北和华北的活动构造 带上; 低温冻害和冰雪灾害在青藏高寒流地区尤为突出; 台风、 风暴潮 多发生在东南沿海地区。 西南伴随地震、 暴雨引起滑坡、 崩塌、 泥石流 和山洪的集群发生。 自然灾害的空间分布还呈现一定的共轭性。 比如, 季风的强弱变化导致了南涝北旱或南旱北涝, 以及一个地区先涝后旱或 先旱后涝现象。 根据国家气象局资料统计, 各种气象灾害平均发生频次 呈增长趋势, 20世纪的 50年代是 19.56次, 60年代为 26.20次, 80年 代达 28.18次。
在地震、 台风、 暴雨、 暴雪等自然灾害发生时, 通常地面无线网络 设备也会受到损毁, 从而导致地面通信中断, 普通的地面移动通信终端 和一些地面应急通信专网系统终端无法发出呼救信息, 为灾后营救工作 带来了困难。 此时卫星移动通信系统仍可正常工作, 但^ ^于卫星终端 体积较大, 通信费用较高的现状, 4艮少有人随身携带卫星终端。 这样面 对突发的灾难, 被困人员仍然没有有效的手段将自己的受损状况和位置 通知给外界, 以获得及时的营救。
因此, 结合地面移动终端和卫星终端功能的卫星和地面通信双模终 端可以有效解决地面通信中断时, 不能收发应急消息的问题。 卫星和地 面通信双模终端中包括地面模块和卫星模块, 由于其卫星模块是按照完 整卫星通信功能设计, 所以卫星和地面通信双模终端的体积大, 不方便 携带, 制作成本高。 另外, 地面模块和卫星模块通常相对独立, 不能智 能的选择合适的方式处理应急通信需求。 发明内容

本申请提出的一种应急通信终端, 依据获取到的终端可用网络的状 态信息, 智能选择利用地面移动通信网络或卫星通信网络中的一种网络 发送紧急消息, 或者利用移动网络和卫星通信网络均发送紧急消息。
当选择利用其中一种网络时, 可以优先选择利用地面移动通信网 络, 发送紧急消息成本低; 也可以优先选择利用卫星通信网络, 发送紧 急消息效率高。
当选择利用两种网络时, 相对于只利用其中一种网络, 提高了发送 紧急消息的成功率。
而且, 还可以依据紧急消息中紧急消息类型所表示的紧急程度, 智 能选择利用哪一种网络或者利用两种网络发送紧急消息。 当紧急程度高 时, 可以选择利用两种网络共同发送紧急消息, 增加成功率; 当紧急程 度不高时, 可以选择利用发送成本低的地面移动通信网络或选择利用效 率高的卫星通信网络, 优先选择地面移动通信网络。
同时, 在应急通信终端中采用优化的卫星通信模块, 优化的卫星通 信模块由于只提供应急通信必要的功能, 精筒掉部分部件或功能(如语 音通信), 所以应急通信终端的体积小, 成本低。 上述实施例中的应急通信终端和应急通信方法可以适用在一种应 急通信系统中, 如图 8所示, 所述系统 100包括:
地面移动通信网络 1001、 卫星通信网络 1002、 应急通信指挥中心 1003和上述应急通信终端;

此外, 应该清楚的是, 不仅可以通过执行计算机所读出的程序代 码, 而且可以通过基于程序代码的指令使计算机上操作的操作系统等 来完成部分或者全部的实际操作, 从而实现上述实施例中任意一项实 施例的功能。
此外, 可以理解的是, 将由存储介质读出的程序代码写到插入计算 机内的扩展板中所设置的存储器中或者写到与计算机相连接的扩展单 元中设置的存储器中, 随后基于程序代码的指令使安装在扩展板或者 扩展单元上的 CPU 等来执行部分和全部实际操作, 从而实现上述实施 例中任一实施例的功能。
