Disaster tolerant method, system and device for virtual private mobile network service

Abstract

The invention discloses a disaster tolerant method, a system and a device for a virtual private mobile network (VPMN) service, which are used for solving the problems that the existing VPMN service needs to be switched to spare SCP equipment when an SCP equipment goes wrong, the input cost is high and a great deal of manpower and a large amount of time resources are needed to be consumed. The disaster tolerant method comprises the following steps that: a calling party exchanger receives a calling request of a calling party, and when the calling party and a called party are VPMN users and a triggered SCP equipment goes wrong, the calling is connected to a called party exchanger; when a conversation is ended, the calling party exchanger and the called party exchanger transmit conversation bills of the calling party and the called party to a BOSS respectively; and the BOSS determines the conversation charges of the calling party and the called party respectively according to the conversation bills of the calling party and the called party, and the corresponding relations between a locally stored user identification and a VPMN group identification to which the user identification belongs and between the locally stored user identification and VPMN tariff information.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a disaster recovery technology for virtual private mobile network (VPMN) services. Background technique [0002] The virtual private mobile network (Virtual Private Mobile Network, VPMN) business provides a high-efficiency, low-cost internal communication LAN service for group customers by establishing a logical voice channel private network on the public mobile communication network. All the users in the same VPMN form a VPMN group, and the purpose of attracting and stabilizing group customers is achieved through the preferential call charges between users in the VPMN group. [0003] The VPMN service is realized based on the mobile intelligent network, and the service control point (Service Control Point, SCP) device on the mobile intelligent network side realizes the call connection to the VPMN user and determines the call fee of the VPMN user. On the mobile intelligent net...
