Method for realizing calling connection control when mobile network exportation user is used as called user

Abstract

The invention discloses a method for realizing the calling connection control when a mobile network exportation user is used as a called user, which comprises the following steps: firstly, detecting a signaling message by a number carrying processor; carrying out decoding to obtain a called user number included in the message when the recognized signaling message is SRI or LOC_REQ; using the number as a key domain; inquiring number carriable database; recognizing whether the called user has the exportation service attribute or not; inserting a network number of an importation network before the called number if the called user is an exportation user; changing the message types into corresponding route inquiry answer messages; and using a subsequent exchange state for transferring the route inquiry answer messages to the called importation network. The invention introduces the independent number processing technology, is independent from the existing communication network, has the advantages of convenience, high speed and safety, and can effectively realize the number carriable service, at the same time, the additional processing capability does not need to be added for the existing communication network exchange equipment and signaling equipment, and various defects of the virtual MSC scheme can be overcome.

Description

technical field [0001] The invention relates to a method for controlling call connection when a mobile network carries out a user as a called party. Specifically, it can be conveniently realized by only using signaling engine technology without modifying the structure of the existing communication network. Carry out the call connection when the user is called. Background technique [0002] When a mobile user is called, the originating office or the mobile gateway office first needs to send SRI (send routing information) or LOC_REQ (location request) to its home HLR (home location register) to query the called routing information, and the HLR needs to go to The VMSC (visiting mobile switching center) where the called user is currently logged in requests routing information, and forwards the routing information to the originating office or mobile gateway office, and the originating office or mobile gateway office establishes a call. [0003] Due to the advancement of number p...

Problems solved by technology

There are many defects in this method: it involves the cooperation of multiple network elements, the processing capacity of the relevant network elements of the existing network will be increased, and there is a requirement for capacity expansion of some network elements; new call connection segments are added to reduce service quality; MNP (Mobile Network Number Portable service) User data are stored in HLR and virtual MSC at the same time, which brings hidden dangers to maintenance
