E.164 domain name analyzing method and DNS server

Abstract

The present invention discloses an analyzing method of an E.164 domain name, which comprises that the information of a plurality of number segments of the E.164 phone number administered by a domain name server is collocated; the E.164 phone number is performed a preprocessing, according to the number segments information collocated, the phone number domain name part of the E.164 domain name is analyzed to a plurality of number segment domain name parts, to form an internal domain name format containing a public domain name part and a plurality of number segment domain name parts; the E.164 domain name is stored each layer nodes of a search tree according to the internal domain name format, to form an internal domain name storage format; after the E.164 domain name searching is received, according to the internal domain name format and the internal domain name storage format, the E.164 domain name requiring searching is searched and matched on the search tree. The present invention also discloses a domain name server. The present invention reduces the height of the search tree and the search complexity, and improves the analyzing efficiency of the domain name.

Description

technical field [0001] The present invention relates to the field of communication network technology, in particular to an E.164 domain name resolution method and a domain name server in ENUM (tElephoneNUmber Mapping, telephone number mapping) service. Background technique [0002] With the development of the information industry, the integration of telecommunication networks and the Internet has become a trend. The diversification of communication means makes each user have many identifications to represent his identity, such as: mobile phone number, fixed phone number, instant message address, electronic Email addresses, personal web pages, etc. At present, these identifications are basically irrelevant, and the amount of these mutually independent identification information that users need to memorize is also increasing. [0003] Based on this, the protocols RFC2916 and RFC3761 defined by the telephone number mapping working group (tElephone NUmber Mapping working group)...

AI Technical Summary

Problems solved by technology

The increase of the domain name level and the increase of the length of the domain name greatly increase the workload of the domain name resolution system

Moreover, if the domain name converted from the E.164 phone number is still processed according to the traditional DNS resolution method, and each number in the domain name is regarded as a node of the domain name tree, this processing method is time-consuming and laborious

[0018] In summary, the existing E.164 domain name analysis technology obviously has inconvenience and defects in actual use, so it is necessary to improve it
