通过该系统，移动端站将经纬度信息通过卫星主站上报至区域管理数据中心；区域管理数据中心设置为基于移动端站的经纬度信息确定移动端站的区域坐标，并将区域坐标所在的管理区域作为移动端站所在的管理区域，从而解决了相关技术中不能确定移动端站所在区域的技术问题,实现了准确确定移动端站的位置的技术效果。
在确定移动端站所在的管理区域时，区域管理数据中心获取按照预设粒度预先划分好的多个管理区域；通过经纬度信息和预设粒度计算出移动端站的区域坐标；确定多个管理区域中与移动端站的区域坐标对应的管理 区域为移动端站所在的管理区域。
可选地，如图2所示，该管理系统还包括：用户终端UE，通过无线接入点AP与移动端站ST连接；AAA(Authentication、Authorization、Accounting)服务器，通过BRAS(Broadband Remote Access Server，简称BRAS)与卫星主站的HUB连接，AAA服务器设置为提供对用户终端的鉴权服务；IMS系统，与所述卫星主站连接，IMS系统设置为提供语音、短信、数据流量等电信多媒体业务；BOSS系统，与卫星主站连接，BOSS(Business&Operation Support System，简称BOSS)系统设置为采集数据业务话单、语音业务话单以及短信业务话单，并根据区域标识提供对应的计费策略。
上述的区域管理数据中心提供有区域标识查询接口和区域标识通知接口，区域管理数据中心通过区域标识通知接口通知移动端站所在管理区域的区域标识，或者在移动端站的区域标识发生变更时，将变更后的区域标识通过区域标识通知接口通知移动端站和AAA服务器；允许用户终端和AAA服务器通过区域标识查询接口查询用户终端所在管理区域的区域标识。
上述的管理系统中，终端APP、卫星端站、卫星主站、宽带远程接入服务器、IP多媒体子系统(IP Multimediea Subsystem，简称IMS)、AAA服务器、区域管理数据中心(Location Based Service，简称LBS)和BOSS计费系统等之间存在关联关系。下面结合图3详述本申请的实施例。
步骤S301，LBS进行区域定义。
上述的区域管理服务中心LBS支持区域定义、区域管理和卫星端站位置的采集，可根据卫星端站的经纬度信息(即位置信息)计算归属区域，存储和管理端站的位置数据、端站区域标识数据和用户区域标识数据，并对外提供端站区域标识查询接口(包括端站区域标识查询接口和用户区域标识查询接口)和区域标识通知接口。
区域管理服务中心的存储部分主要由位置信息存储器、端站区域标识 存储器、用户区域标识存储器、区域数据存储器组成。
步骤S302，卫星端站通过GPS实时采集经纬度信息(即位置信息)。
步骤S303，卫星端站上传实时采集到的经纬度信息给LBS，如果卫星端站是第一次上报或卫星端站的区域位置发生变化时，LBS主动通知AAA和卫星端站。
步骤S304，LBS存储接收到的经纬度信息，根据卫星端站的经纬度信息计算其归属区域。
步骤S305，在确定了卫星端站的归属区域(所属的管理区域)后，即可根据既定的区域定义确定其对应的区域标识(即分析区域标识)。
在用户终端接入卫星端站时，从卫星端站获取区域信息，卫星端站的区域信息发生变化时，主动将区域信息发送给用户终端，用户终端显示区域标识。
步骤S306，在确定了卫星基站的归属区域和区域标识，即可对其进行区域管理(如提供基于区域的服务，如语音服务、数据服务等)。
步骤S307，LBS在处理数据业务时对区域标识的处理。
例如，用户终端使用数据业务时，通过用户账号在AAA上进行接入鉴权，并建立会话控制，AAA生成话单时，根据用户终端的IP地址和用户账号，从LBS查询端站的区域标识，将区域标识填入话单中，同时，LBS根据用户终端IP地址计算出卫星端站ID，保存用户账号和卫星端站的映射关系。
在进行语音业务处理时，可通过如下步骤实现：
步骤S308，识别端站区域标识。
步骤S309，终端显示区域标识。
用户终端使用语音业务时，用户终端上的APP定时(如每分钟)从端站获取区域标识，并进行显示。
步骤S310，终端发起语音业务。
终端APP作为主叫时，通过SCP Invite信令把区域标识带给主站，再由主站通过SIP Invite信令发给IMS。终端APP作为被叫时，通过SCP Invite信令把区域标识信息带给主站HUB，再由主站HUB通过SIP信令发给IMS。
步骤S311，处理语音业务。
BOSS提供全业务运营支撑，如采集数据上网业务话单、语音业务和短信等业务话单，实现多业务融合计费，根据话单中的区域标识，进行不同的计费策略，实现区域计费功能。
在上述实施例中，可以将卫星覆盖的广袤区域按要求划分成不同的逻辑管理单元(即管理区域)，终端APP显示区域标识，运营商可以根据区域标识提供差异化的服务和计费策略，并为宽带卫星通信用户提供与传统移动运营一致的业务体验。
实施例2
根据本发明实施例，提供了一种卫星通信的区域管理方法的方法实施例，需要说明的是，在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行，并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
图4是根据本发明实施例的卫星通信的区域管理方法的流程图，如图4所示，该方法包括：
步骤S401，移动端站将经纬度信息通过卫星主站上报至区域管理数据中心。
步骤S402，区域管理数据中心基于移动端站的经纬度信息确定移动端站的区域坐标，并将区域坐标所在的管理区域作为移动端站所在的管理区域。
通过上述实施例，移动端站将经纬度信息通过卫星主站上报至区域管理数据中心；区域管理数据中心基于移动端站的经纬度信息确定移动端站的区域坐标，并将区域坐标所在的管理区域作为移动端站所在的管理区域。从而解决了相关技术中不能确定移动端站所在区域的技术问题，实现了准 确确定移动端站的位置的技术效果。
在区域管理数据中心基于移动端站的经纬度信息确定移动端站的区域坐标之后，区域管理数据中心将与移动端站的区域坐标所在的管理区域对应的区域标识发送至移动端站；在用户终端接入移动端站时，获取移动端站上保存的区域标识。
具体地，在用户终端接入移动端站时，获取移动端站上保存的区域标识时，用户终端通过无线访问接入点接入移动端站；用户终端从移动端站获取保存的区域标识，将移动端站保存的区域标识作为用户终端所在管理区域的区域标识，并显示所在管理区域的区域标识。
LBS是移动卫星端站的区域管理数据中心，负责区域定义，端站经纬度信息采集，端站区域标识分析，并向外提供区域标识服务，交互流程如图5所示。
步骤S501，端站获取GPS经纬度信息(即位置信息)，为减少传输开销，将经纬度信息封装在端站心跳消息中上报给主站。
步骤S502，主站将收到的端站心跳消息进行汇总，上报汇总的端站位置消息给LBS。
步骤S503，LBS对上报消息进行解析，将端站的ID和GPS经纬度信息存储在数据库中，完成端站经纬度信息的采集。
步骤S504，根据管理区域定义和端站的经纬度信息，计算端站属于哪个管理区域(即分析区域标识)，若端站的区域有变更，则更新该端站的区域标识，同时向端站、AAA发送端站区域更新消息，通知更新端站区域标识。
在上述实施例中，区域管理数据中心基于移动端站的经纬度信息确定移动端站的区域坐标，并将区域坐标所在的管理区域作为移动端站所在的管理区域包括：区域管理数据中心获取按照预设粒度预先划分好的多个管理区域；区域管理数据中心通过经纬度信息和预设粒度计算出移动端站的区域坐标；区域管理数据中心确定多个管理区域中与移动端站的区域坐标 对应的管理区域为移动端站所在的管理区域。
具体地，区域管理数据中心通过经纬度信息和预设粒度计算出移动端站的区域坐标包括：区域管理数据中心通过经纬度信息中的纬度LAT和预设粒度G计算出区域坐标中的横坐标M＝ROUNDUP(LAT/G，0)，其中，ROUNDUP为向上取整的函数；区域管理数据中心通过经纬度信息中的经度LON和预设粒度G计算出区域坐标中的纵坐标N＝ROUNDUP(LON/G，0)。
上述的管理区域可依据经纬度进行栅格划分，最大分辨率为1度，最小分辨率为0.1度，根据管理粒度需求设置划分的分辨率，分辨率定义为K(1<K<10)。
管理划分后形成一个矩形阵列(如图6所示)，用户可以基于此矩形阵列进行管理区域的定义，不同的区域包含一系列的矩形区域，如图6中的A区域和B区域，区域定义信息保存在数据库中。
根据区域定义和端站经纬度信息，可以分析出端站的区域标识，分析算法参考流程图7，这是种高效快速的检索算法，先依据经度计算出矩阵横坐标M，根据纬度计算出矩阵纵坐标N，然后从区域定义矩阵中检索到对应[M,N]的区域标识。
若端站的区域标识发生了变化，如从A区域切换到B区域，则区域管理服务(LBS)会通过消息接口通知到各网元。
步骤S701，LBS收到端站经纬度(LAT,LON)位置，LAT表示经度，LON表示维度。
步骤S702，获取区域划分粒度参数K，K＝1/G，G为粒度。
步骤S703，计算出位置矩阵坐标，横坐标M＝ROUNDUP(LAT*K,0),纵坐标N＝ROUNDUP(LON*K,0)。
步骤S704，根据矩阵坐标(M，N)，区域定义矩阵中查询区域标识L。
步骤S705，判断L是否为-1，若是则执行步骤S707，否则执行步骤 S708。
步骤S706，确定区域未定义。
步骤S707，设置端站区域标识为未知。
步骤S708，处于定义区域，更新端站区域标识为L。
步骤S709，判断区域标识是否更新，若是则执行步骤S710，否则结束。
步骤S710，发送更新通知至用户终端。
可选地，在获取移动端站上保存的区域标识之后，在区域管理数据中心根据移动端站的当前经纬度信息重新确定移动端站所在的管理区域时，若移动端站所在的管理区域发生变更，区域管理数据中心则将与变更后的管理区域对应的区域标识发送至移动端站，以更新移动端站保存的区域标识；移动端站将更新后的区域标识发送至用户终端。在终端上显示区域标识，用户可以明确了解所处的区域，交互流程如图8所示：
步骤S801，端站保存实时的区域标识信息，终端通过AP接入时，通过账号进行登录。
步骤S802，在端站的管理区域切换时，LBS从端站获取区域标识，并获取与更新后的管理区域对应的区域信息。
步骤S803，LBS发送区域变化通知至主站。
步骤S804，主站转发区域变化通知至端站。
步骤S805，端站转发区域变化通知至终端。
步骤S806，终端显示更新后的区域标识信息。
LBS计算到端站区域标识更新时，会通知到主站，主站再通知端站更新区域标识，端站更新后，会同时通知下挂的所有终端，终端接收到消息后，更新区域标识显示。
可选地，在区域管理数据中心将与移动端站所在的管理区域对应的区域标识发送至移动端站的同时，区域管理数据中心将与移动端站所在管理 区域对应的区域标识发送至AAA服务器进行保存。
在区域管理数据中心将与移动端站所在管理区域对应的区域标识发送至AAA服务器进行保存之后，在区域管理数据中心根据移动端站的当前经纬度信息重新确定移动端站所在的管理区域时，若移动端站所在的管理区域发生变更，区域管理数据中心则将与变更后的管理区域对应的区域标识发送至AAA服务器，以更新AAA服务器保存的区域标识。
在本申请中，在用户终端接入移动端站之后，可通过如下方式提供数据业务：在用户终端通过移动端站向卫星主站发起数据业务请求时，AAA服务器从数据业务请求中获取用户终端的IP地址和/或账户信息；AAA服务器通过账户信息对用户终端进行鉴权；在对用户终端的鉴权通过后，AAA服务器发送用户终端的IP地址和/或账户信息至区域管理数据中心，以查询用户终端的区域标识；区域管理数据中心通过用户终端的IP地址和/或账户信息确定移动端站所在管理区域的区域标识，并将移动端站所在管理区域的区域标识作为用户终端所在管理区域的区域标识发送至AAA服务器；AAA服务器将接收到的用户终端的区域标识记录到用户终端的数据业务话单信息中。
上述的区域管理数据中心通过用户终端的IP地址和/或账户信息确定移动端站所在管理区域的区域标识包括：区域管理数据中心通过用户终端的IP地址和/或账户信息确定移动端站的ID，并通过移动端站的ID从数据库中查询移动端站所在管理区域的区域标识。
上述的AAA负责与LBS进行接口，负责数据相关业务的区域标识处理，交互流程参见图9：
步骤S901，LBS检测端站区域是否更新，区域是否发生切换。
步骤S902，检测到端站区域更新时，通过区域切换变化通知，通知AAA更新对应端站的区域标识。
步骤S903，终端通过账号登录。

步骤S905，LBS根据IP计算端站的ID，由端站ID查询对应端站的区域标识作为终端区域标识返回。
步骤S906，AAA保存终端会话的区域标识，并在数据业务话单信息中填充对应的区域标识信息，即填写话单。
步骤S907，LBS根据接口参数中的用户上网账号，反向生成账号区域标识信息数据，并保存账号、端站ID和区域标识的映射关系，作为账号区域标识数据的基础。
语音等传统移动业务的区域标识由终端提供，因为终端中已经有实时的区域标识信息，由终端APP发起的传统移动业务时，可以将区域标识在信令中进行填充，提供与传统移动业务一致的体验。
在区域管理数据中心通过用户终端的IP地址和/或账户信息确定移动端站所在管理区域的区域标识之后，区域管理数据中心保存用户终端的账户信息、移动端站的ID以及移动端站所在管理区域的区域标识之间的映射关系。这样，在下次用户使用该业务时，可以根据账户信息、移动端站的ID中的任一信息进行区域标识的查询。
可选地，在用户终端接入移动端站之后，在用户终端发起语音呼叫时，通过SCP INVITE信息把用户终端所在管理区域的区域标识发送至移动端站，由移动端站将SCP INVITE信息转发至卫星主站；卫星主站在接收到SCP INVITE信息后，将SCP INVITE信息中携带的区域标识携带于SIP INVTE信息中，发送至IMS系统；IMS系统接收到SIP INVTE信息后，保存SIP INVTE信息中携带的区域标识；IMS系统在生成对应于语音呼叫的语音业务话单时，将保存的区域标识记录到语音业务话单中。
具体地，下面以语音呼叫为例，说明实现原理，交互流程如图10所示：
步骤S1001，终端通过APP发起语音呼叫时，查询本地终端的区域标 识信息。
步骤S1002，终端在SCP语音呼叫请求的INVITE消息中填充区域标识信息。
步骤S1003，端站收到SCP INVITE消息后转发给主站。
步骤S1004，主站向IMS发起SIP INVITE信令(也即SIP INVITE消息)，信令中携带区域标识信息。
步骤S1005，IMS收到INVITE信令后，保存用户的区域标识，生成语音话单时，将区域标识填写入话单的区域标识位中。
在上述实施例中，本申请的方法具有如下优点：管理区域支持用户可定制，可以满足不同业务发展需要；提供和传统移动业务一致的用户体验；资源开销小，节省了宝贵的卫星带宽资源；不需要专业的卫星手持终端，支持普通的终端设备，面向普通的用户，应用范围广；同时支持数据、语音、短信和其他补充业务进行融合计费。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明的技术方案本质上或者说对相关技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本发明各个实施例所述的方法。
