Description

一种PC实现A-GPS的方法 技术领域
本发明属于PC技术领域，尤其涉及一种PC实现A-GPS（辅助卫星定位）的方法。
背景技术
A-GPS，即Assisted-GPS（辅助卫星定位），指位置服务器接收并解调GPS卫星信号，然后根据终端所处的大概位置计算相应的GPS辅助参数，这些GPS辅助参数通过移动通信网络下发给终端，终端利用GPS辅助参数能够加快对GPS卫星信号的捕获并降低了对GPS卫星信号强度的要求，然后终端利用GPS辅助参数完成对GPS卫星信号的伪距测量，根据伪距测量结果，由终端或者网络服务器计算出最终的位置信息。
A-GPS的应用分为两种模式：一种是SI模式，指的是由终端发起定位的模式；另一种是 NI模式，指的是由网络服务器发起定位的模式。
AGPS解决方案的优势主要在其定位精度上。在室外等空旷地区，其精度在正常的GPS工作环境下，可达10米左右，堪称目前定位精度最高的一种定位技术。AGPS解决方案的另一优点为：首次捕获GPS信号的时间一般仅需几秒，不像GPS的首次捕获时间可能要2～3分钟。
而如何在具备上网功能的PC上实现A-GPS是现有技术尚未解决的问题，因此，需要提供一种技术方案，可以在PC上实现A-GPS功能。

附图说明
图1是本发明实施例一流程图；
图2是本发明实施例二流程图。
 本发明的最佳实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
实施例一：具备上网功能的PC通过SI模式实现A-GPS
具备上网功能的PC通过SI模式实现A-GPS的流程如图1所示，具体包括如下的步骤：
1、PC控制其无线网络模块拨号上网，发起GPS定位会话；
2、PC将其自身的基站地址通过网络传输到位置服务器；
3、位置服务器根据PC的大概位置（基站地址）反馈与该位置相关的GPS辅助信息到PC；
4、PC开启其A-GPS接收模块，根据位置服务器传输的GPS辅助信息接收当前卫星信息；
5、PC根据当前卫星信息计算其到卫星的伪距；
6、PC根据计算出的伪距计算出位置信息，通过UI（用户界面）显示卫星信息和位置信息。
具体应用本发明提供的技术方案时，PC计算出其到卫星的伪距之后，可以根据伪距计算其位置信息，也可以将伪距通过网络传输到位置服务器，由位置服务器根据伪距计算位置信息，并将计算出的位置信息传输到PC。
本发明的实施方式
实施例二：具备上网功能的PC通过NI模式实现A-GPS
具备上网功能的PC通过NI模式实现A-GPS的流程如图2所示，具体包括如下的步骤：
1、网络的位置请求服务器向PC发送请求定位的Wap Push消息；
2、PC根据对Wap Push消息的解析控制其无线网络模块拨号上网；
3、PC将其自身的基站地址通过网络传输到位置服务器；
4、位置服务器根据PC的大概位置反馈与该位置相关的GPS辅助信息到PC；
5、PC开启其A-GPS接收模块，根据位置服务器传输的GPS辅助信息接收当前卫星信息；
6、PC根据当前卫星信息计算其到卫星的伪距；
7、PC根据计算出的伪距计算出位置信息，将卫星信息和位置信息通过网络传输到位置请求服务器。
具体应用本发明提供的技术方案时，PC计算出其到卫星的伪距之后，可以根据伪距计算其位置信息，也可以将伪距通过网络传输到位置服务器，由位置服务器根据伪距计算位置信息，并将计算出的位置信息传输到PC，然后由PC将卫星信息和位置信息通过网络传输到位置请求服务器.
本实施例中，PC 要通过NI模式实现A-GPS功能，就需要分离位置请求服务器传输的Wap Push消息。位置请求服务器发送过来的Wap Push消息是包含特定标识的Push消息，是可以与彩信和其他类型的Push消息分离的。
对于位置请求的Wap Push消息中包含Content Type（内容类型）和Application ID（应用识别号）字段分别为下表所示：
Content Type Application ID
application/vnd.omaloc-supl-init x-oma-application:ulp.ua
PC可以通过以上字段分离出位置请求的Wap Push消息，然后根据Wap Push消息启动定位会话流程。
PC通过NI模式实现A-GPS，可以实现查询他人位置的服务。
在实施例一和实施例二中，PC控制其无线网络模块拨号上网时可以采用相应的拨号AT命令（AT Commands），如：
ATD*99#<CR>
在每次需要开启GPS定位会话前先检查当前是否已经连接网络，如果没有，则需要先进行拨号连接。PC 在进行A-GPS定位前，还需要获取几个重要的无线网络参数：
MCC – Mobile Country Code （移动国家代码）；
MNC – Mobile Network Code ( 移动网络代码)；
LAC – Location Area Code （位置区域代码）；
CID – Cell Identifier （小区标识符）；
IMSI – International Mobile Subscriber Identity （国际移动用户标识）。
以上参数都可以通过AT命令获取：
AT+CCED=0,1<CR> 或AT^DCNL<CR> 可以得到 MCC, MNC, LAC和CID参数信息；
AT+CIMI<CR> 可以得到 IMSI参数信息。
此外，PC的 上层应用是通过底层驱动送上来的NMEA（National Marine Electronics Association" 国际航运电子协会）格式数据来获取卫星信息以及位置信息的。PC的底层驱动在获取到当前卫星信息和位置信息后，将获取到的当前卫星信息以及位置信息转换为NMEA格式数据，然后送给上层应用解析。NEMA数据中，通过 $GPGGA段的数据指示了GPS的定位数据，包括时间、位置以及和GPS接收机相关的数据；$GPGSA段指示了当前激活的卫星；$GPGSV段指示了当前可见的卫星的信息等等。具体可以参考NEMA相关协议资料。
如上所述，本发明提供的技术方案将A-GPS功能应用在PC上，为PC提供定位及导航服务，关键是应用PC的无线网络模块提供的网络功能连接相应的A-GPS服务器获取当前卫星的GPS辅助信息，加快PC获取当前卫星数据的速度，然后准确计算PC的当前位置信息。本发明实施例提供的方案还可以实现PC的NI模式定位功能，该功能可实现查询他人位置的服务。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
