Communication support method and system based on number portability

Abstract

The invention discloses communication support method and system based on number portability. The method comprises the steps of: additionally setting an important user database in a local mobile communication network system, wherein number section information preserved for an important user is stored in the important user database; setting a number portability service pointing at the number section for the important user, and establishing a mapping relation between an old telephone number of the important user and a new telephone number; closing HLR (Home Location Register) or limiting the user in the HLR on using the local mobile communication network, wherein at this moment, if the important user calls a call, a visitor location register is interacted with the important user database forcompleting authentication and calling; if a common user calls a call, because the HLR in which the common user is located is closed, the visitor location register (VLR) finds out the service of the user is limited when carrying out the authentication, therefore, the communication is interrupted during the authentication state. The invention has low implementation cost, and can realize that the important users can be centrally managed.

Description

technical field [0001] The present invention relates to the communication field, in particular to a communication guarantee method and system based on number portability. Background technique [0002] When natural disasters or social public security incidents occur, on the one hand, the traffic on the network increases sharply due to the panic of the masses, which eventually leads to communication interruption; on the other hand, criminals use communication channels to spread bad information that endangers national security and undermines national unity. Therefore, in special time periods and special places, it is necessary to take some necessary measures to guarantee the communication of important users, and at the same time restrict the communication of irrelevant users. Therefore, it is necessary to design a communication guarantee method. [0003] At present, most of the restrictions on user communication in the communication network are to modify or increase the informa...

AI Technical Summary

Problems solved by technology

However, this technical solution has the following defects: it is completed by changing the information in the user's SIM card, which requires customization of the UE to distinguish important users from ordinary users. Therefore, the access network equipment BTS (base transceiver station, base station), BSC (base station controller, base station controller) and the core network equipment MSC (Mobile Switching Center, mobile switching center) need to be completely transformed

When the limited user range is relatively large, the number of BTS, BSC and MSC that needs to be transformed will also be large, so the cost is huge

At the same time, due to the scattered users, it is not necessary to implement unified management
