  • the invention realizes the acquisition of POI related information by mapping the POIs of geographical points of interest into IPv6 unicast addresses, IPv6 multicast addresses, and domain names.
  • IP addresses have become the basis for Internet interconnection and identity differentiation. With the continuous expansion of the Internet, IPv4 addresses are gradually consumed, and the next-generation Internet based on IPv6 is getting more and more widely used.
  • An IPv6 address can be a unicast address or a multicast address. In traditional unicast transmission, a point-to-point network connection is implemented between the sender and each receiver. If a sender transmits the same data to multiple receivers at the same time, multiple copies of the same data packet must also be copied accordingly.
  • Multicast solves the problem of low efficiency in unicast mode.
  • the multicast source that is, the sender of the multicast information
  • the multicast router uses the multicast routing protocol to establish a tree-like route for the multicast data packets. Reproduction and distribution began at the forks as far as possible.
  • IPv6 multicast group addresses There are many types of IPv6 multicast group addresses. Common multicast addresses based on unicast prefixes are shown in Figure 1: The highest 8 bits are 0xFF, which identifies this address as a multicast address. The next 4 bits are the Flag bit, and the most significant bit of the Flag bit is 0; the R bit indicates whether the multicast address is embedded with RP; the P bit indicates whether the multicast address is generated based on a unicast prefix; the T bit indicates multicast Whether the address is assigned permanently or temporarily. It can be seen that Flag is identified according to the attributes of a multicast address, its generation method, and other attributes. The next 4 bits indicate the range of the multicast. The common ranges are node local, link local, site local, and institution local. .

Description

基于地理兴趣点编码的位置相关信息访问方法及装置 技术领域
本发明涉及计算机网络技术领域，特别涉及一种基于地理兴趣点编码的位置相关信息访问方法及装置。
背景技术
目前已经有很多上网装置，能够通过附着至网络的装置进行地理定位，以确定其自身的地理位置。然而，处于一个位置的上网装置，仍然很难接接收到针对这一位置的特定信息，也难于和周边的上网装置通讯。本发明通过将地理兴趣点POI映射为IPv6单播地址、IPv6组播地址、域名，来实现POI相关信息的获得。
互联网上的每一个节点都依靠IP地址互相区分和相互联系，IP地址成了整个互联网互联互通、身份区分的基础。随着互联网规模的不断扩张，IPv4地址逐渐消耗，以IPv6为基础的下一代互联网正在得到越来越广泛的应用。IPv6地址可以是单播地址或者组播地址，在传统的单播传输中，在发送者和每一接收者之间实现点对点网络连接。如果一台发送者同时给多个的接收者传输相同的数据，也必须相应的复制多份的相同数据包。如果有大量主机希望获得数据包的同一份拷贝时，将导致发送者负担沉重、延迟长、网络拥塞；为保证一定的服务质量需增加硬件和带宽。组播解决了单播方式效率低的问题。当网络中的某些用户需求特定信息时，组播源(即组播信息发送者)仅发送一次信息，组播路由器借助组播路由协议为组播数据包建立树型路由，被传递的信息在尽可能远的分叉路口才开始复制和分发。
IPv6的组播组地址格式有很多，常见的基于单播前缀的组播地址如图1所示：最高的8个比特为0xFF，标识此地址为组播地址。接着的4个比特为Flag位，Flag位的最高位为0；R比特表示是否是内嵌RP的组播地址；P比特表示组播地址是否是基于单播前缀生成的；T比特表示组播地址是永久分配的还是临时分配的。可以看出，Flag根据一个组播地址的功能、生成方式等属性进行了标识，之后的4个比特为表示组播的范围，常见的范围有节点本地、链路本地、站点本地、机构本地等。
DNS(Domain Name System域名系统)是互联网的一项核心服务，它作为可以将域名和IP地址相互映射的一个分布式数据库，能够使人更方便的访问互联网，而不用去记住能够被机器直接读取的IP数串。DNS通过允许一个名称服务器把他的一部分名称服务委托 给子服务器而实现了一种层次结构的名称空间。所谓层次型命名机制，就是在名字中加入结构，而这种结构是层次型的。名字空间不再采用集中式管理，而是被划分成若干部分，每一部分授权给某个机构管理，授权管理机构可以将其所管辖的名字空间进一步划分，进一步授权给若干子机构管理。如此下去，名字空间管理组织形成一种层次型树形结构，其中每一节点(包括各层管理机构和最后的主机节点)都有一个相应的标识符，主机的名字就是从树叶到树根路径上各节点标识符的有序序列。显然，只要同一子树下每层节点的标识符不冲突，主机名绝对不会冲突，DNS的这一层次结构如图一所示。其中的每个组成部分就是一个域，从直观上来看，DNS域名就是由“.”连接起来的一连串的字符。例如：www.tsinghua.edu.cn，其中顶级域为cn域，第二级域为中国教育和科研计算机网络的域“edu.cn”，第三级域为清华大学的域“tsinghua.edu.cn”。

具体实施方式
下面参照附图描述根据本发明实施例提出的基于地理兴趣点编码的位置相关信息访问方法及系统，首先将参照附图描述根据本发明实施例提出的基于地理兴趣点编码的位置相关信息访问方法。
图1为根据本发明一个实施例的基于地理兴趣点编码的位置相关信息访问方法的流程图。
如图1所示，该基于地理兴趣点编码的位置相关信息访问方法包括以下步骤：
在步骤S101中，将地理兴趣点编码映射成IPv6单播地址，或将地理兴趣点编码映射成IPv6组播地址，或将地理兴趣点编码映射成域名。
在步骤S102中，通过访问地理兴趣点编码映射成IPv6单播地址，或加入地理兴趣点编码映射成IPv6组播组，或访问地理兴趣点编码映射成的域名，以得到地理兴趣点的位置相关信息。
具体而言，在本发明的一个实施例中，通过对地理兴趣点(POI)进行编码，映射为IPv6单播地址、组播地址或DNS域名，当用户输入该单播IPv6地址或DNS域名时，即可以访问该地址对应的站点，通过访问该站点，可以获得该兴趣点的相关信息。或者用户可以通过加入对该兴趣点所编码成的IPv6组播组，接收到关于该兴趣点的信息或与同样加入该组播组的其他用户通信。如图2所示，其具体步骤为：
在步骤S1中：判断POI是否有地名编码？如果有，则转入步骤S2，否则转入步骤S3。
在步骤S2中：获得地名编码，并设置标识符为0，然后可以通过步骤S4获得POI映射成的IPv6单播地址，通过步骤S5获得POI映射成的IPv6组播地址，通过步骤S6获得POI映射成的域名。
在步骤S3中：根据地理上相近的POI编码，注册得到标识符，例如12比特的标识符，然后可以通过步骤S4获得POI映射成的IPv6单播地址，通过步骤S5获得POI映射成的IPv6组播地址，通过步骤S6获得POI映射成的域名。
在步骤S4中：将POI映射成IPv6单播地址。
在步骤S5中：将POI映射成IPv6组播地址。
S6：将POI映射成域名。
具体而言，在本发明的一个实施例中，地理兴趣点通常标识一个地理位置区域，该区域中的位置都可以作为该地理兴趣点的一部分，而且具备广泛的用户接受程度。在本发明的一个实施例中，以清华大学李兆基大楼为例，大楼中的任一层和任一房间，都是清华大学李兆基大楼的一部分，而且当用户提及清华大学李兆基大楼时，所指的就是该楼中的位置的集合。传统的地理信息采集方法需要地图测绘人员采用精密的测绘仪器去获取一个兴趣点的经纬度，然后再标记下来。每个POI包含四方面信息，名称、类别、坐标、分类，全面的POI讯息是丰富导航地图的必备资讯，及时的POI兴趣点能提醒用户路况的分支及周边建筑的详尽信息，也能方便导航中查到你所需要的各个地方。
可以理解的是，POI之间具有较为复杂的关系，例如，有些POI点之间具有包含关系，例如清华大学李兆基大楼这个POI点就包含于清华大学这一POI点中，有些POI点对应着同一个位置，例如清华园和清华大学是同一个位置的两种称呼，而有些POI点则互相之间有交叉，例如华清嘉园和五道口之间，就有一定的交叠。
进一步地，国家已经就地名数据库实现建立了一套编码模式，国家地名数据库代码依据国家标准《中华人民共和国行政区划代码》(GB2260)、《县以下行政区划代码编制规则》(GB10114一88)的编码规则、《民政统计代码编制规则》和《地名分类与类别代码编制规则》(GB/T18521-2001)制定。国家地名数据库代码共有20位数字，分为四段。以下简介这四段的规范：
第一段由6位数字组成，表示县级以上行政区划代码,执行《中华人民共和国行政区划代码》(GB/T 2260-2002)。行政区划数字代码(简称数字码)采用三层六位层次码结构，按层次分别表示我国各省(自治区、直辖市、特别行政区)、市(地区、自治州、盟)、县(自治县、县级市、旗、自治旗、市辖区、林区、特区)。数字码码位结构从左至右的含义是：第一层即前两位代码表示省、自治区、直辖市、特别行政区。第二层即中间两位代码表示市、地区、自治州、盟、直辖市所辖市辖区/县汇总码、省(自治区)直辖县级行政区划汇总码，其中01～20、51～70表示市，01、02还用于表示直辖市所辖市辖区、县汇总码；21～50表示地区、自治州、盟；90表示省(自治区)直辖县级行政区划汇总码。第三层即后两位表示县、自治县、县级市、旗、自治旗、市辖区、林区、特区，其中：01～20表示市辖区、地区(自治州、盟)辖县级市、市辖特区以及省(自治区)直辖县级行政区划中的县级市，01通常表示市辖区汇总码；21～80表示县、自治县、旗、自治旗、林区、地区辖特区；81～99表示省(自治区)辖县级市。
第二段的3位代码执行国家标准《县以下行政区划代码编制规则》(GB/T10114-2003)。其中的第一位数字为类别标识，以“0”表示街道，“1”表示镇，“2和3”表示乡，“4和5”表示 政企合一的单位；其中的第二位、第三位数字为该代码段中各行政区划的顺序号。具体划分如下:
1.001—099表示街道的代码，应在本地区的范围内由小到大顺序编写；
2.100—199表示镇(民族镇)的代码，应在本地区的范围内由小到大顺序编写；
3.200—399表示乡(民族乡)的代码，应在本地区的范围内由小到大顺序编写；
4.400—599表示政企合一单位的代码，应在本地区的范围内由小到大顺序编写；
5.600-699表示开发区等非法定单位代码，应在本地区的范围内由小到大顺序编写；
6.999表示省、地、区(县)本级的代码，应在本地区的范围内编写。
第三段由5位数字组成，表示地名属性类别，执行《地名分类与类别代码编制规则》(GB/T 18521-2001)。
第四段为6位数字，表示附加码，具体代码段为000000-999999，用以区分同一类别并且是同一行政区的地名并进行排序，如果前13位编码可以确定此地名的唯一性，则第四段代码用000000表示。
在本发明的一个实施例中，针对一个具有20位编码的地名POI，可以将这20位编码映射到IPv6地址中，从而形成POI编码映射成的IPv6单播地址，用户可以访问这一个地址，以得到该POI点所相关的信息。
本发明的一个实施例中，将一个地理兴趣点POI，编码映射为IPv6单播地址中，从而形成POI编码映射成的IPv6单播地址，用户可以访问这一个地址，以得到该POI点所相关的信息。
特别的，可以使用如下方法进行映射：使用7比特编码省级行政区部分、7比特映射市级行政区部分、7比特映射县级行政区部分、10比特映射街道乡级行政区部分；使用20比特映射附加码部分，这51比特放置在IPv6地址的中间部分，其中后面补零，从而实现POI到单播地址的映射，如图4所示。
特别的，如果使用一个IPv6的/32子网进行映射的话，可以将第33比特保留(设置为0)，之后31比特用来编码省级、市级、县级、街道乡级编码，后64比特中的前20比特用来编码附加码，之后的44比特全部设置为零。
特别的，针对一个没有在数据库中编码的地名POI，可以选择与该POI点地理上最接近的POI，并注册得到一个标识符，例如选择一个12比特的标识符注册，然后将这一标识编码入IPv6地址中附加码之后。
在本发明的以一个实施例中，可以将一个地理兴趣点POI，编码映射为IPv6组播地址，用户可以加入该组播地址所标识的组，以接收该POI点所发布的信息。
特别的，映射方法如下，选择32比特的组播前缀，第33比特为保留位(设置为0)， 然后使用7比特编码省级行政区部分、7比特映射市级行政区部分、7比特映射县级行政区部分、10比特映射街道乡级行政区部分；使用20比特映射附加码部分，这51比特放置在IPv6地址的中间部分，然后12比特为0，最后32比特为组播的组ID，如图5所示。
特别的，针对一个没有在数据库中编码的地名POI，可以选择与该POI点地理上最接近的POI，并注册得到标识符，例如选择一个12比特的标识符注册，然后将这一标识编码入IPv6地址中附加码之后。
本发明的一个实施例中，将一个地理兴趣点POI，编码映射为域名，用户可以访问这一个域名所对应的站点，以得到该POI点相关的信息。
特别的，映射方法如下，省级行政区部分、市级行政区部分、县级行政区部分、街道乡级行政区由字典产生，附加码部分采用码表映射方式进行编码，如图6所示。
特别的，在本发明的一个实施例中，可以采用5比特的BASE32编码方法进行编码，这样20比特的附加码可以映射为4个字母。BASE32编码如图7所示
特别的，在本发明的一个实施例中，针对一个没有在数据库中编码的地名POI，可以选择与该POI点地理上最接近的POI，并通过注册页面注册自己的附加码，然后将这一标识作为DNS域名的最前一项。
特别的，在本发明的一个实施例中，用户可以认领一个附加码所对应的站点，并为这一站点选择别名，通过选择别名，可以使用更为通俗的方法来标识该兴趣点所对应的站点。为与编码形成的名字相区别，该别名长度应当多于或者少于4个字符，或者存在BASE32所不使用的字符如0、1、8、9。
本发明实施例的基于地理兴趣点编码的位置相关信息访问方法，通过将地理兴趣点(POI)，通过进行编码，映射为IPv6单播地址、组播地址或DNS域名，当用户输入该单播IPv6地址或DNS域名时，即可以访问该地址对应的站点，通过访问该站点，可以获得该兴趣点的相关信息。或者用户可以通过加入对该兴趣点所编码成的IPv6组播组，接收到关于该兴趣点的信息或与同样加入该组播组的其他用户通信，具有方便用户在访问站点时获取地理兴趣点的优点，提升用户体验。
其次参照附图描述根据本发明实施例提出的基于地理兴趣点编码的位置相关信息访问系统。

如图8所示，该基于地理兴趣点编码的位置相关信息访问系统10包括：判断模块100、第一获取模块200、第二获取模块300和编码模块400。
其中，判断模块100用于判断地理兴趣点是否有地名编码。第一获取模块200用于如 果有地名编码，则获取地理兴趣点的地理兴趣点编码，并设置标识符为0。第二获取模块300如果没有地名编码，则根据满足预设条件的地理点获取地理兴趣点编码，并注册得到标识符，其中，注册得到标识符包括12比特的标识符。编码模块400用于将地理兴趣点编码映射成IPv6单播地址，且将述地理兴趣点编码映射成IPv6组播地址，并且将地理兴趣点编码映射成域名，以得到地理兴趣点的位置相关信息。该基于地理兴趣点编码的位置相关信息访问系统10具有方便用户在访问站点时获取地理兴趣点的优点，提升用户体验。
进一步地，在本发明的一个实施例中，编码模块300进一步包括：第一映射单元，用于通过7比特编码省级行政区部分、7比特映射市级行政区部分、7比特映射县级行政区部分、10比特映射街道乡级行政区部分；第二映射模块，用于通过20比特映射附加码部分，且51比特放置在IPv6地址的中间部分，后面补零，以实现POI到单播地址的映射。
