Embodiment Construction

[0041] The embodiment of the present invention proposes a new FMC system framework and related devices. The key entities in the framework include: a new FMC functional entity FMCN (FMC network), a Wi-Fi / Cellular dual-mode FMC terminal supporting the SIP protocol, and a solid-state Network access gateway GW functional modules, etc. Among them, the FMCN is used to realize the FMC-related functions of the system, and the comprehensive function gateway GW provides the access capability of the terminal on the fixed network side, and supports the effective integration of the PSTN network and the broadband network.

[0042] In addition, the embodiment of the present invention also proposes related processes such as registration / deregistration of the FMC terminal at the fixed network access point, session communication, and mutual handover with the mobile network based on the above-mentioned FMC network architecture.

[0043] The specific implementation structure of the system provide...

Abstract

The invention relates to a communication system, a gateway, an entity and a method for realizing a call. The invention mainly comprises a network entity and an access gateway, wherein, the network entity is used for maintaining position parameter information of a terminal, implementing route selection operation of a conversation which relates to the terminal according to the position parameter information and switching the conversation between a public switched telephone network and a mobile network; the access gateway is used for providing a wireless interface, a broadband network interface and a public switched telephone network interface and processing the exchange and the conversion of the information among the interfaces. Therefore, the realization of the invention can cause users in PSTN to fully utilize resources in the PSTN for realizing the mobile access through the fixed network access gateway.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to an implementation scheme for integrating PSTN and mobile network. Background technique [0002] FMC (Fixed-Mobile Convergence, the convergence of fixed and mobile networks) technology refers to a comprehensive solution that users can enjoy the same communication services and obtain the same applications in both fixed and mobile environments. Since the development of FMC services can help fixed network operators make use of the existing fixed network resources that have been built at high cost, attract new customers, and gain stronger competitiveness, the provision of FMC services is of great significance to fixed network operators. [0003] At present, in the FMC technology, the utilization of fixed broadband network resources is specifically considered, and a multi-mode terminal method is adopted to realize the integration of fixed and mobile networks. In the mult...
