Description
Technical field
The present invention relates to networking telephone field, relate in particular to a kind of method, system and user terminal of setting up voip call.
Background technology
Support VoIP (Voice over Internet Protocol, the networking telephone) business in 3GPP (the 3rd Generation Partner Project, third generation partner program) LTE (LongTerm Evolution, the Long Term Evolution) technology.VoIP be will simulation sound signal after overcompression and package, in the business that the enterprising lang sound of IP (Internet Protocol, Internet protocol) network signal transmits, be also referred to as Internet Protocol telephone or IP phone with the form of data packet.
In the LTE technology, after the user terminal start, need provide log-on message to mobile core network.When user terminal need be set up voip call, also needing provided the application layer log-on message to the call center, and its state information need regularly be provided.Because mobile core network and call center adhere to two different types of networks separately, so user terminal must provide log-on message to mobile core network and call center respectively.
User terminal need carry out PDP (Packet Data Protocol, packet data protocol) and activate before call center's registration, to set up data link transmission data.Set up data link in case carry out the PDP activation, charge system just begins user terminal is chargeed, and when promptly user terminal does not begin to set up voip call, just needs to pay in advance, otherwise just can't use the voip phone business.
Among the LTE, the method for setting up voip call mainly is divided into following three kinds at present:
First method is: user terminal start back keeps the PDP state of activation constantly.
In this method, no matter whether need to set up voip call after the user terminal start, all need to carry out PDP and activate.
The shortcoming of first method is: because after the PDP activation, charge system just begins user terminal is chargeed, therefore can cause user terminal when not making a phone call, also to be in the charging state, cause unexpected expenditure, and user terminal takies base station resource all the time, and is very unfavorable for the elevator system capacity.
Second method is: user terminal carries out PDP and activates in setting up the voip call process.
In this method, when setting up voip call, register to the call center.
The shortcoming of second method is: user terminal can only be called out and set up other user terminals that PDP activates, and for not setting up other user terminals that PDP activates, then can not call out; In addition and since voip call with carry out simultaneously to call center registration, so Signalling exchange is too complicated in the call establishment, causes call setup very slow.
The third method is: user terminal uses DNS (DomainName System, domain name system) that telephone number is resolved not to the registration of voip call center.
In this method, to e.164 encode and give dns resolution as domain name, e.164 coded system is to use e.164 address, DDDS (Dynamic Delegation Discovery System, dynamic delegation discovery system) and DNS with one group of unified agreement of telephone system and internet.At this moment, same method two carries out PDP and activates in setting up the voip call process, but therefore user terminal can speed call set up process not to call center's registration.
The shortcoming of the 3rd class methods is: because user terminal can only carry out the calling of point-to-point to call center registration, and can't utilize value-added services such as calling transfer that the call center provides, Call Waiting.
In addition, in said method two and method three, carry out simultaneously because voip call and PDP activate, called user terminal can be carried out by twice prompting and confirm the reception program.Be illustrated in figure 1 as and set up the voip call schematic flow sheet in the method three, carry out for the first time and confirm that the reception program is: called user terminal need confirm whether to carry out PDP to be activated, if adopt not alerting pattern this moment, carry out PDP automatically by system and activate, can cause charged extra; Carry out for the second time and confirm that the reception program is: called user terminal need confirm whether receive phone.Therefore, complex operation when called user terminal receives phone does not meet the phone receive mode among the present PSTN (PublicSwitched Telephone Network, PSTN).
