Description
Technical Field
The invention relates to the technical field of computer networks, in particular to a position related information access method and system based on geographical interest point codes.
Background
There are many internet access devices that can be geographically located by a device attached to the network to determine its own geographic location. However, it is still difficult for the internet access device at a location to receive specific information for the location and to communicate with the surrounding internet access devices. The invention realizes the acquisition of POI related information by mapping the geographical point of interest (POI) into IPv6 unicast address, IPv6 multicast address and domain name.
Every node on the internet is distinguished and contacted with each other by means of an IP address, and the IP address forms the basis of the interconnection and intercommunication and identity distinguishing of the whole internet. With the continuous expansion of the internet scale, the IPv4 address is gradually consumed, and the next generation internet based on IPv6 is becoming more and more widely used. The IPv6 address may be a unicast address or a multicast address, where in conventional unicast transmission a point-to-point network connection is implemented between the sender and each recipient. If a sender transmits the same data to multiple receivers at the same time, multiple copies of the same data packet must be copied accordingly. If a large number of hosts wish to obtain the same copy of a packet, this can result in heavy sender burden, long delay, and network congestion; hardware and bandwidth are increased to ensure a certain quality of service. The multicast solves the problem of low efficiency of the unicast mode. When some users in the network need specific information, the multicast source (i.e. the multicast information sender) only sends the information once, the multicast router establishes tree-type routing for the multicast data packet by means of the multicast routing protocol, and the transmitted information begins to be copied and distributed at the fork intersection as far as possible.
There are many multicast group address formats of IPv6, and a common multicast address based on unicast prefix is shown in fig. 1: the top 8 bits are 0xFF, identifying this address as a multicast address. The next 4 bits are Flag bits, and the highest bit of the Flag bits is 0; the R bit indicates whether the multicast address is the multicast address of the embedded RP; the P bit indicates whether the multicast address is generated based on the unicast prefix; the T bit indicates whether the multicast address is permanently assigned or temporarily assigned. It can be seen that Flag is identified according to attributes such as function and generation mode of a multicast address, the following 4 bits are used to indicate a multicast range, and common ranges include node local, link local, site local, mechanism local, and the like.
The DNS (Domain Name System) is a core service of the internet, and as a distributed database that maps Domain names and IP addresses to each other, it enables people to access the internet more conveniently without remembering IP strings that can be read directly by machines. DNS enables a hierarchical namespace by allowing a name server to delegate some of its name services to sub-servers. The hierarchical naming mechanism is to add a structure to the name, and the structure is hierarchical. The name space is not managed in a centralized mode, but is divided into a plurality of parts, each part is authorized to be managed by a certain organization, and the name space managed by the authorized management organization can be further divided into a plurality of sub-organizations. In doing so, the namespace management organization forms a hierarchical tree structure in which each node (including each level of the management organization and the last host node) has a corresponding identifier, and the host name is an ordered sequence of node identifiers along the path from the leaf to the root of the tree. Obviously, as long as the identifiers of each level of nodes under the same subtree do not conflict, the host names never conflict, and the hierarchical structure of the DNS is shown in fig. one. Each component is a domain, and intuitively, a DNS domain name is a series of characters connected by ". ang". For example: www.tsinghua.edu.cn, wherein the top level domain is cn domain, the second level domain is the domain "edu.cn" of the computer network for education and research in china, and the third level domain is the domain "tsinghua university" of qinghua university.

Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The method and system for accessing location related information based on geo-point of interest coding according to the embodiments of the present invention will be described with reference to the accompanying drawings.
Fig. 1 is a flowchart of a location-related information access method based on geo-point of interest coding according to an embodiment of the present invention.
As shown in fig. 1, the method for accessing location-related information based on geo-point of interest coding includes the following steps:
in step S101, the geographical interest point code is mapped to an IPv6 unicast address, or the geographical interest point code is mapped to an IPv6 multicast address, or the geographical interest point code is mapped to a domain name.
In step S102, the location related information of the geographic interest point is obtained by accessing the mapping of the geographic interest point code to the IPv6 unicast address, or joining the mapping of the geographic interest point code to the IPv6 multicast group, or accessing the domain name mapped by the geographic interest point code.
Specifically, in an embodiment of the present invention, a geographic point of interest (POI) is encoded and mapped to an IPv6 unicast address, a multicast address, or a DNS domain name, so that when a user inputs the unicast IPv6 address or the DNS domain name, the site corresponding to the address can be accessed, and by accessing the site, the relevant information of the POI can be obtained. Or the user may receive information about the point of interest by joining the IPv6 multicast group encoded for the point of interest or communicate with other users who also join the multicast group. As shown in fig. 2, the method comprises the following specific steps:
in step S1: determine if the POI has a place name encoded? If yes, the process proceeds to step S2, otherwise, the process proceeds to step S3.
In step S2: the location name code is obtained and the identifier is set to 0, and then the IPv6 unicast address to which the POI is mapped may be obtained through step S4, the IPv6 multicast address to which the POI is mapped may be obtained through step S5, and the domain name to which the POI is mapped may be obtained through step S6.
In step S3: according to the geographically close POI codes, an identifier, for example, a 12-bit identifier is registered, and then the IPv6 unicast address to which the POI is mapped may be obtained through step S4, the IPv6 multicast address to which the POI is mapped may be obtained through step S5, and the domain name to which the POI is mapped may be obtained through step S6.
In step S4: the POI is mapped to an IPv6 unicast address.
In step S5: and mapping the POI into the IPv6 multicast address.
S6: the POI is mapped to a domain name.
Specifically, in one embodiment of the present invention, a geographic point of interest generally identifies a geographic location area, and the locations in the area may be included as part of the geographic point of interest and have a wide range of user acceptance. In one embodiment of the invention, taking the university of qinghua lymegaly building as an example, any floor and any room in the building is part of the university of qinghua lymegaly building, and when a user refers to the university of qinghua lymegaly building, that is, a collection of locations in that building. The traditional geographic information acquisition method requires a mapping staff to acquire the longitude and latitude of a point of interest by using a precise mapping instrument and then mark the point of interest. Each POI comprises four-aspect information, name, category, coordinate and classification, comprehensive POI information is necessary information for enriching a navigation map, timely POI interest points can remind a user of branches of road conditions and detailed information of surrounding buildings, and all places needed by the user can be conveniently searched in navigation.
It is understood that there are more complex relationships between POIs, for example, there are some POI spots with inclusion relationships, for example, the luhua university lymegak building is included in the luhua university POI spot, some POI spots correspond to the same location, for example, the luhua garden and the luhua university are two names of the same location, and some POI spots have intersections, for example, there is some overlap between the luhua garden and the five road junctions.
Furthermore, a set of coding modes is established by the country with respect to the implementation of the place name database, and the national place name database codes are formulated according to the coding rules of the national standard 'administrative division codes of the people's republic of China (GB2260), 'administrative division code formulation rules below county' (GB 10114-88), 'civil administration statistical code formulation rules' and 'place name classification and category code formulation rules' (GB/T18521-2001). The country place name database code has 20 digits in total and is divided into four segments. The specifications of these four sections are summarized below:
the first segment is composed of 6 digits, represents administrative division codes above county level, and executes the administrative division codes of the people's republic of China (GB/T2260-. The administrative division digital code (abbreviated as digital code) adopts a three-layer six-bit hierarchical code structure, and represents each province (autonomous region, direct administration city, special administrative region), city (region, autonomous state, union) and county (autonomous county, county-level city, flag, autonomous flag, city and district, forest district and special district) of China according to the hierarchy. The meaning of the code bit structure of the digital code from left to right is: the first two codes represent province, autonomous region, direct city and special administrative region. The second layer, namely the middle two-digit code represents a city/county summary code of the prefecture, the district, the autonomous state, the union, the direct prefecture city, and a province (autonomous region) direct prefecture county level administrative division summary code, wherein 01-20 and 51-70 represent cities, and 01 and 02 are also used for representing a prefecture summary code of the prefecture city and the prefecture county of the direct prefecture city; 21-50 represent region, autonomous state, union; and 90 denotes a province (municipality) through prefecture level administrative division summary code. The third layer, namely the last two digits, represents county, self-government county, county-level city, flag, self-government flag, district of the city, forest district, and special district, wherein: 01-20 represents a county level city in a district of the city, a prefecture level city of the district (autonomous state, union), a prefecture level city of the city, and a prefecture level administrative district of the province (autonomous region), wherein 01 generally represents a city and prefecture area summary code; 21-80 represents county, autonomous county, flag, autonomous flag, forest district, regional district; 81-99 represent prefecture-level cities in provinces (autonomous districts).
The 3-bit code of the second segment executes the national standard administrative division code establishment rules under county (GB/T10114-2003). The first digit is a category identifier, 0 is used for representing a street, 1 is used for representing a town, 2 and 3 are used for representing a county, and 4 and 5 are used for representing a unit integrating the government and the enterprise; the second digit and the third digit are the sequence numbers of each administrative region in the code segment. The method is specifically divided into the following steps:
1.001-099 represent the codes of streets, which should be written in the range of the local area from small to big;
2.100-199 represent codes of town (national town), which should be written in the range of local area from small to big;
3.200-399 codes of villages (national villages) are written in the range of the local area from small to big;
4.400-599 represent codes of a government-enterprise unified unit, which should be written in a local area from small to big in sequence;
5.600-699 show illegal single-order location codes of development areas and the like, which should be written in the range of the local area from small to big;
6.999 shows the code of province, region, district (county) level, which should be written in the range of the local district.
The third section is composed of 5 digits and represents the place name attribute category, and executes the place name classification and category code establishment rule (GB/T18521-2001).
The fourth segment is a 6-digit number and represents an additional code, the specific code segment is 000000-999999 and is used for distinguishing and sorting place names of the same category and the same administrative district, and if the first 13-digit code can determine the uniqueness of the place names, the fourth segment code is represented by 000000.
In one embodiment of the invention, for a place name POI with 20-bit code, the 20-bit code can be mapped into the IPv6 address, so as to form an IPv6 unicast address to which the POI code is mapped, and the user can access the address to obtain information related to the POI point.
In one embodiment of the invention, a geographical point of interest (POI) is coded and mapped into an IPv6 unicast address, so that an IPv6 unicast address mapped by the POI code is formed, and a user can access the address to obtain information related to the POI.
In particular, the following method may be used for mapping: using 7-bit coding provincial administrative district parts, 7-bit mapping city administrative district parts, 7-bit mapping county administrative district parts and 10-bit mapping street county administrative district parts; the 20-bit map additional code portion is used, and these 51 bits are placed in the middle portion of the IPv6 address with zero padding followed, thereby achieving the mapping of the POI to the unicast address, as shown in fig. 4.
In particular, if a/32 subnet of IPv6 is used for mapping, bit 33 may be reserved (set to 0), then 31 bits are used to encode provincial, urban, county, street county codes, the first 20 bits of the last 64 bits are used to encode additional codes, and the last 44 bits are all set to zero.
Specifically, for a place name POI not encoded in the database, the POI geographically closest to the POI point may be selected and registered to obtain an identifier, for example, a 12-bit identifier registration is selected, and then this identifier is encoded into the IPv6 address after the additional code.
In one embodiment of the present invention, a geographical point of interest POI may be coded and mapped to an IPv6 multicast address, and a user may join a group identified by the multicast address to receive information published by the POI.
Specifically, the mapping method is that a 32-bit multicast prefix is selected, the 33 th bit is a reserved bit (set to 0), and then a 7-bit coding provincial administrative district part, a 7-bit mapping urban administrative district part, a 7-bit mapping county administrative district part and a 10-bit mapping street and county administrative district part are used; the additional code part is mapped using 20 bits, and the 51 bits are placed in the middle part of the IPv6 address, then 12 bits are 0, and finally 32 bits are the group ID of the multicast, as shown in fig. 5.
Specifically, for a place name POI not encoded in the database, the POI geographically closest to the POI point may be selected and registered to obtain the identifier, for example, a 12-bit identifier registration is selected, and then this identifier is encoded into the IPv6 address after the additional code.
In an embodiment of the present invention, a geographical point of interest POI is coded and mapped to a domain name, and a user can access a site corresponding to the domain name to obtain information related to the POI.
Specifically, the mapping method is as follows, the provincial administrative district section, the urban administrative district section, the county administrative district section, and the street administrative district are generated by a dictionary, and the additional code section is encoded by using a code table mapping method, as shown in fig. 6.
Specifically, in one embodiment of the present invention, the encoding may be performed using a 5-bit BASE32 encoding method, so that 20-bit additional codes may be mapped to 4 letters. BASE32 encoding is shown in FIG. 7
In particular, in one embodiment of the present invention, for a location name POI not encoded in the database, the POI geographically closest to the POI location may be selected and its additional code registered via the registration page, and this identification is then used as the top entry of the DNS domain name.
In particular, in one embodiment of the present invention, the user may claim a site corresponding to an additional code and select an alias for the site, and by selecting the alias, a more popular method may be used to identify the site corresponding to the point of interest. To distinguish from the names formed by the encodings, the alias length should be more or less than 4 characters, or there are characters such as 0, 1, 8, 9 that are not used by BASE 32.
According to the position related information access method based on the geographical interest point codes, the geographical interest Points (POI) are coded and mapped to IPv6 unicast addresses, multicast addresses or DNS domain names, when a user inputs the unicast IPv6 addresses or the DNS domain names, the site corresponding to the addresses can be accessed, and the related information of the interest points can be obtained by accessing the site. Or the user can receive the information about the interest point or communicate with other users who also join the multicast group by joining the IPv6 multicast group coded by the interest point, so that the method has the advantages of facilitating the user to acquire the geographical interest point when visiting the site and improving the user experience.
Next, a location related information access system based on geographical point of interest codes proposed according to an embodiment of the present invention will be described with reference to the accompanying drawings.
Fig. 8 is a schematic structural diagram of a location-related information access system based on geo-point of interest coding according to an embodiment of the present invention.
As shown in fig. 8, the system 10 for accessing location related information based on geo-point of interest coding includes: a judging module 100, a first obtaining module 200, a second obtaining module 300 and an encoding module 400.
