Realization method and device for cross-domain bidirectional mobile telephone service

Abstract

This invention provides a realization method and a device for a cross-domain bidirectional mobile telephone service. The realization method for the cross-domain bidirectional mobile telephone service comprises steps of installing a calling control software and loading an SIP standard protocol on an intelligent terminal, performing setting on a legal wireless network access point through a software, automatically comparing mobile communication network coverage to a broadband wireless access point coverage before imitating a call, initiating authentication and certification to a background server, choosing a suitable network to initiate a call according to a defined strategy and user favors after the authentication is passed. If the call is initiated through a circuit domain of the mobile communication network, the called mobile phone displays the number of the calling mobile phone, and if the calling party initiate the calling through the broadband wireless access point accessing the internet packet domain, the called mobile phone displays a fixed network number which is distributed to the legal calling party by a webmaster of a core network. As a result, one-user-two-number binding is achieved.

Description

technical field [0001] The present invention relates to the fields of mobile communication and wireless Internet, in particular to a method and device for implementing a voice call across the circuit domain of the mobile communication network and the packet domain of the wireless Internet network. Background technique [0002] At present, mobile communication networks and wireless Internet networks have spread in every corner of people's lives, and the integration between mobile communication networks and fixed communication has been sufficient, and voice calls and data intercommunication between different networks can basically be achieved. However, in the existing communication field, there is no method to implement two-way voice calls between the circuit domain of the mobile communication network and the packet domain of wireless broadband access to the Internet. Under the current background of network convergence, many applications will not be able to accomplish. [000...

Problems solved by technology

However, in the existing communication field, there is no method to implement two-way voice calls between the circuit domain of the mobile communication network and the packet domain of wireless broadband access to the Internet. Under the current background of network convergence, many applications will not be able to accomplish

[0003] Among the existing technologies for implementing cross-domain calls, one supports calls from the mobile network circuit domain to the Internet packet domain, but it is only a one-way call. The independent judgment and selection between wireless Internet signals cannot guarantee the service quality of calls, and there is no authentication management mechanism for subscribers; the other is to realize cross-domain two-way calls, but only in the circuit domain and the mobile communication network. Calls Between Packet Domains

At present, there is no method and system for two-way calls with perfect contract management and quality control from the mobile communication circuit domain to the wireless Internet packet domain
