Communication system based on VoIP/IM technique and roaming communication method of communication system

Abstract

The invention provides a communication system based on a VoIP / IM technique and a roaming communication method of the communication system. The communication system mainly comprises a control module, a local VoIP / IM client module and a roaming place VoIP / IM client module, wherein the control module controls a telephone module and the local VoIP / IM client module to achieve connection and releasing of a voice communication link and transmitting short texts and address book information between the telephone modue and the local VoIP / IM client module; the local VoIP / IM client module is based on a VoIP / IM protocol which is installed on a local PC, connected with the control module and controlled by the control module, and transmits voice, the short texts and the address book information between the control module and a VoIP / IM server; the roaming place VoIP / IM client module communicates with the local VoIP / IM client module through the VoIP / IM server. When the communication system is used, telephone numbers are needless to be replaced, a person can conveniently keep in touch with a person in a local place or a native person in a roaming place and communication cost is low.

Description

technical field [0001] The invention relates to an application of VoIP / IM technology in the communication field, in particular to a communication system based on VoIP / IM technology and a roaming communication method thereof. . Background technique [0002] Due to work needs, business people often travel to other cities in China or abroad. When they are in roaming places, they also need to maintain voice communication with local relatives and friends or domestic relatives and friends. The roaming costs incurred are quite expensive. Buy a roaming phone card after the local area to change its mobile phone number, and at the same time notify its new number to all the people who have been in contact before. Relatives and friends need to store the telephone number of its roaming place, and will delete the telephone number of its roaming place again after its roaming comes back, will bring trouble to relatives and friends. If the new number cannot be notified to all the people wh...

Problems solved by technology

If the new number cannot be notified in time to everyone who has been in contact with it before, or if someone does not store their roaming phone number in time, it will lead to the consequences of missing important text messages and calls

[0003] In order to solve the above problems, someone has proposed a solution using existing remote control software on the market. The remote control software is a client / server program. However, this solution has the following problems: (1) If the client and the server are not in the same local area network, the limited bandwidth of the network and uncertain routing will cause large and variable network delays, some remote The control software is realized through the mechanism of transmitting images and messages. The time delay will cause the image transmission of such software to be incomplete, and remote services cannot be provided at all.

(2) Running such software on the user's mobile phone will consume a large amount of mobile phone traffic of the user

[0004] Someone also proposed another solution, which is similar to the newly launched VoIP and instant messaging application Jego of China Mobile International. There are also problems in this solution. The network operator needs to change the mobile communication network system when developing the application, and the research and development cost is very high. In comparison, the research and development cost of the present invention is relatively low, and there is no restriction on the type of user's mobile phone
