Problems solved by technology

[0003] However, in practical applications, operator A needs to go through a multi-level ENUM query to obtain the routing information of operator B corresponding to the called user. For example, operator A sequentially passes through the second level ( Tier2) ENUM, first level (Tier1) ENUM, basic level (Tier0) ENUM, and the corresponding basic level (Tier0) ENUM, first level (Tier1) ENUM, second level (Tier2) ENUM of the second region can Obtain the routing information of the operator B corresponding to the called user; the query process has the following defects: (1) currently most countries or regions do not have ENUM at the national level, that is, the Tier1 level, and the construction is slow; (2) Some operators are unwilling to open mutual inquiry between ENUMs due to security and profit considerations; 3) The process of ENUM inquiry is too complicated, and the international inquiry is user-by-user inquiry, which is inefficient and time-consuming

Abstract

The embodiment of the invention discloses a network intercommunication method, comprising the steps of receiving a route search request sent by a first interconnection boundary control entity, wherein the route search request is the search request generated by a first interconnection boundary control entity according to a communication request of a calling user, and the communication request is used for making a request for communication with a called user; obtaining first number segment information corresponding to the route search request according to the route search request, wherein the first number segment information represents the number segment information corresponding to the called user; searching first construction domain name information corresponding to the first number segment information; and obtaining route information of the called user according to the first construction domain name information, thereby enabling the calling user to establish communication connection with the called user. The embodiment of the invention also discloses a network entity and a control entity.

Description

technical field [0001] The present invention relates to intercommunication and interconnection technologies, in particular to a network intercommunication method, a network entity, and a control entity. Background technique [0002] In the existing interworking scheme, there are two interconnection nodes in the circuit domain (CS domain) and the interconnection protocol (IP, Internet Protocol) multimedia subsystem (IMS, IP Multimedia Subsystem) domain between the network, that is, the IMS domain. Routing problem; the current international standard defines the mode of query + OB (Originating Breakout) for telephone number mapping (ENUM, E.164Number URI Mapping), specifically, such as figure 1 As shown, the calling user corresponding to operator A sends a query request to ENUM, requesting to query the routing information of the called user, and operator A performs routing selection based on the query results fed back by ENUM, such as the called operator, called capability, etc...
