Problems solved by technology

[0004] Therefore, in the existing solution, inter-provincial calls between CS network users in different provinces can only pass through the CS long-distance network, occupying the port resources of the traditional long-distance network, and cannot take advantage of the advantages brought by the IP interworking of the IMS network

Embodiment 1

[0102] The present invention provides a first embodiment of a call routing system, the system of this embodiment can be used to execute Figure 4 The technical solution of the shown method embodiment, the system of this embodiment includes:

[0103] The first MGCF, including Figure 5 The device shown is used to receive the call request sent by the CS network in the first-level area, determine the first-level area to which the called number included in the call request belongs according to the configured number segment information of each first-level area, and When determining that the called number is not the number of the current primary area, routing the call request to the second MGCF of the primary area to which the called number belongs;

[0104] said second MGCF, comprising Figure 7 The shown device is configured to receive the call request sent by the first MGCF, and send the call request to the CS network of the primary area to which the called number belongs;

Abstract

The invention provides a route calling method, device and system, and relates to the technical field of communications. The method comprises the steps that a calling request sent by a CS network in a first-level region is received by a first MGCF; a first-level region which a called number contained in the calling request belongs to is determined by the first MGCF according to configured number information of each first-level region; if the number does not belong to the first-level region, the calling request is routed to a second MGCF of the first-level region which the called number belongs to by the first MGCF so that the calling request can be routed to a CS network in the first-level region which the called number belongs to by the second MGCF. According to the technical scheme of the route calling method, device and system, cross-region calling between CS network users is unclogged through an IMS network, terminal resources of traditional long-distance networks are saved, and advantages of the IMS network can be fully utilized.

Description

technical field [0001] The present invention relates to the communication field, in particular to a call routing method, device and system. Background technique [0002] IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) is a brand-new multimedia service form. As a technology that can realize all-IP networks, its main features are simplicity, flexibility, open standards, and independence from access networks. IMS The network can meet the needs of current end customers for more novel and diversified multimedia services, and has become the core part of the next-generation converged communication system, and it is also the evolution direction of the language exchange network. [0003] During the future development of the IMS network, it will coexist with CS (circuit switching, circuit switching)-based telephone networks (including PLMN, GSM and other circuit switching networks) for a long period of time. Therefore, the realization of IMS network and CS network Traffic inte...
