Description
Technical field
The present invention relates to a kind of technical field of communication conversion, especially a kind of sides that GSM communications are switched to VOIP communications
Method.
Background technology
Global system for mobile communications Global System for Mobile Communication are just well-known
GSM is the most commonly used mobile phone standard of current application.Global more than 200 countries and regions, which are more than 1,000,000,000 people, to be made
With GSM phones.The ubiquitous world for sign " Roaming agreements " rear user between mobile-phone carrier of GSM standard
Roaming becomes very usually.GSM compared with its pervious standard maximum be not both it signaling and voice channel be all digital
, therefore GSM is counted as the second generation (2G) mobile telephone system.This illustrates digital communication from having been built up very early to being
In system.GSM is an open standard currently developed by 3GPP.With science and technology development, GSM communications are relatively universal
, while with the development of science and technology, there is VOIP.VOIP (Voice over Internet Protocol) i.e. network electricity
Words, also referred to as Internet Protocol telephone or IP phone are by voice signal in Public Switched Telephone Network (PSTN, Public
Switched Telephone Network) it is converted between internet (Internet), voice signal is compressed
Encapsulation carries out the transmission of voice signal in the form of data packet.Current VOIP platforms have generally comprised VOIP gateways, SIP
Server and the multiple voip client ends for belonging to the VOIP platforms.Wherein, VOIP gateways be with PSTN network (such as electricity
Believe carrier network) PSTN gateway be connected, for communicating connection VOIP platforms and PSTN network.And sip server is responsible for
The control of communication signaling, is mainly used for and one or more participants create, change and terminate session.User can use
Communicating terminal, such as mobile phone in PSTN networks etc. is dialed at voip client end, which by VOIP platforms, has the end of communication function
End equipment.But current voip client end is substantially not providing and terminates the function of answering a call using voip client, it is main former
If to answer ordinary calls because being voip client end, it is necessary to call forwarding is set on GSM communicating terminals (such as mobile phone),
The incoming call of the telephone number of communicating terminal described in all-calls is transferred to VOIP platforms.And it is provided with and exhales in communicating terminal
After crying transfer, when dialing the telephone number of this communicating terminal using another voip client end, calling is to be transferred to institute
It states on the corresponding voip client end of telephone number, at this time if the voip client end is online, VOIP visitors can be passed through
Family termination is taken on the telephone；If but the voip client end it is not online when, the VOIP platforms can dial this phone by PSTN gateway
Number, and this telephone number called is transferred to VOIP platforms, can thus form endless loop, is provided so as to cause whole system
Source (junction line) exhausts, thus how by GSM communication be quickly transferred to VOIP communication it is particularly important.
Invention content
It is provided the purpose of the present invention is to solve above-mentioned the deficiencies in the prior art and a kind of GSM communications are switched to VOIP and lead to
The method of news
To achieve the goals above, a kind of method that GSM communications are switched to VOIP communications designed by the present invention, specific steps are such as
Under：
Step S1, when GSM communicating terminals receive the calling for coming from PSTN network, call forwarding work(is quickly opened immediately
Can, the sip server at voip client end is transferred them to carry out subsequenct call；
Step S2, when the sip server judges that the subsequenct call comes from PSTN network, and whether voip client end is detected
Online, if online, directly opening VOIP communications, if voip client end is not online, the SIP servers return, and prompt to exhale
It cries and is not turned on message.
Further, the step S2 includes：
The sip server carries out special identifier on the number transmitted when calling is transferred to the VOIP platforms, with
Indicate that the calling comes from PSTN networks；The SIP servers initiate multiple subsequenct call to the VOIP clients；
If the VOIP clients are not online, the SIP servers return, and prompt non-answered call message.
Further, in step sl, the calling for coming from PSTN network received by the GSM communicating terminals, be by
The calling that another GSM communicating terminal is initiated by the PSTN network to the communicating terminal, or by another voip client
Hold the calling initiated to the communicating terminal by the VOIP platforms and the PSTN network.
Further, in step s 2, the sip server is to return to non-answered call message to another GSM to lead to
Terminal is interrogated, while the subsequenct call is terminated by the sip server.
Further, in step sl, the calling for coming from PSTN network received by the GSM communicating terminals, be by
The calling that another voip client end is initiated by the VOIP platforms to the VOIP clients, wherein the process of the calling
Including：
Another VOIP clients are initiated to call by the VOIP platforms to the VOIP clients；If described
Voip client end is not online, and the sip server has correspondence by the PSTN network to the voip client end
The GSM communicating terminals forward the calling；If the GSM communicating terminals are provided with call forwarding to the voip client
End, the calling are transferred to the sip server to carry out subsequenct call.
Further, in step s 2, the sip server is to return to non-answered call message to another VOIP visitors
Family end, while the subsequenct call is terminated by the sip server or another voip client end.
A kind of method that GSM communications are switched to VOIP communications that the present invention obtains, can effectively determine in the prior art
The endless loop problem easy tod produce can also thoroughly solve GSM communicating terminals are quickly converted into VOIP in the prior art
The problem of communication.
Specific implementation mode
Innovation and creation are described further with reference to embodiment.
