Embodiment Construction

[0040] Embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0041] Aiming at the problem that in the existing ENUM / DNS recursive query, the inconsistency between the query modes set by the ENUM / DNS on the calling side and the secondary ENUM / DNS server on the called side leads to query failure and call failure, the embodiment of the present invention An ENUM / DNS recursive query method, device and system are provided to solve this problem.

[0042] In the technical solution provided by the embodiment of the present invention, in the case that the setting query modes of the calling side ENUM / DNS and the secondary ENUM / DNS server of the called side are inconsistent, the secondary ENUM / DNS server of the called side passes Negotiate to obtain the result ...

Abstract

The invention discloses a recursive query method, device and system of ENUM / DNS (telephone number mapping group / domain name system). The problem that the query is failed since the query modes set by a calling side secondary ENUM / DNS server and a called side secondary ENUM / DNS server are inconsistent is solved; after receiving a query message from the call side secondary ENUM / DNS server forwarded by a primary ENUM / DNS server, the called side secondary ENUM / DNS server sends a query condition matching request for requesting the feedback of query content expressed by a query condition configured by the called side secondary ENUM / DNS server after judging and determining that the query content expressed by a query condition format in the query message is inconsistent with the query condition self-configured by the called side secondary ENUM / DNS server, and then queries according to the feedback query content.

Description

technical field [0001] The present invention relates to the technical field of Telephone Number Mapping Group (ENUM, Telephone Number Mapping Group) / Domain Name System (Domain Name System) of Internet (IP, Internet Protocol) Multimedia Subsystem (IMS, IP Multimedia Subsystem) network, specifically, relates to An ENUM / DNS recursive query method, device and system. Background technique [0002] At present, in the IMS network of mobile communication, when performing domain name query for the ENUM of the mobile phone number, there are usually the following three methods: [0003] The first method, address query (A query): Obtain the IP address of the domain name according to the domain name, and the IMS network element in the area where the ENUM / DNS is located can provide domain name resolution. For example, the client (such as Serving Call Session Control Function (S-CSCF, S-CSCF)) initiates an A query to the ENUM / DNS server, assuming that the input is "icscf.ims.gd.chinamobil...
