Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
First execution mode of the present invention as shown in Figure 1.
First terminal as caller is initiated multimedia call by communication network to network equipment.Network equipment is routed to this multimedia call as the second called terminal.The present invention does not have special requirement to the type of communication network and terminal.Communication network can be a mobile communications network, Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access for example, abbreviation " WCDMA ") network, TD SDMA (Time Division Synchronous Code Division MultipleAccess is called for short " TD-SCDMA ") network etc.; Also can be fixed communication network, for example PSTN, NGN etc.; Even can be to move the network that merges with immobile phase.Terminal can mobile phone also can fixed telephone etc.First terminal and second terminal can be the terminals of identical or different type, and for example first terminal is a mobile phone, and second terminal is a fixed telephone.Network equipment is then looked the difference of communication network and in general difference is the equipment with function of exchange, for example Softswitch.
If second terminal is not supported or can not be accepted multimedia call, then send the message that multimedia call was not supported or can not be accepted to expression second terminal to network equipment, for example require to discharge the message of this multimedia call.Second terminal does not support that the common cause of multimedia call is that this terminal models is older, does not have corresponding ability.Because development of Communication Technique is maked rapid progress, the terminal of often last generation even earlier generations does not also reach the new technology of lifetime and occurs, so the old and new's terminal can be found everywhere with the phenomenon of depositing in network.Another second terminal does not support that the reason of multimedia call may be the not signatory corresponding business of user of this terminal, and operator provides the multimedia call service for this user.
After network equipment is received this message, indicate first terminal to discharge the multimedia call of its initiation.First terminal is hung up the telephone according to the indication of network side.
After this, network equipment is initiated audio call to first terminal and second terminal respectively.After first terminal and second terminal were received this audio call, the user was reminded in ring on the one hand, sends ALERTING message (Alerting message) to network equipment on the other hand.
Network equipment is waited for calling subscriber and called subscriber's off-hook after receiving ALERTING message.If first terminal of original caller is prior to the second terminal off-hook, then network equipment can be to the first terminal plays ring-back tone or other prompt tones; If original second called terminal is prior to the first terminal off-hook, then network equipment can be to the other prompt tone of second terminal plays.The purpose of playing RBT or prompt tone is to allow former calling subscriber and former called subscriber can know current call progress situation.Why different with the prompt tone of second terminal plays to first terminal, be in order to give the user with good business experience.Because former calling subscriber initiatively makes a call, wish to hear the ring-back tone of opposite end traditionally.And former called subscriber and not knowing to cause the calling of ring be that network side is initiated, rather than former calling subscriber's initiation, so former traditionally called subscriber wishes can converse once picking up the telephone, this moment, first terminal may also not have off-hook again after hanging up original multimedia call, so need inform this situation to former called subscriber by prompt tone.
When first terminal and second terminal all behind the off-hook, network equipment is connected this two terminals.Because connect two the off-hook terminal be the technology that can realize at present, so do not elaborated in the present invention.
Second execution mode of the present invention as shown in Figure 2.The main distinction of second execution mode and first execution mode is, network equipment is by from second terminal response of multimedia call being known whether second terminal is not supported maybe can not accept multimedia call in first execution mode, and network equipment is that the attribute information of second terminal of preserving by the requester network side judges whether second terminal is not supported maybe can not accept multimedia call in second execution mode.For example, at global system for mobile communications (Global Systemfor mobile Communication, be called for short " GSM ") in, play (the Mobile Switching Center of mobile switching centre of exchange interaction, be called for short " MSC ") can be to attaching position register (HomeLocation Register, abbreviation " HLR ") inquiry second terminal use's CAMEL-Subscription-Information, if this user does not have the signatory business relevant with multimedia call, think that then second terminal can not accept multimedia call, directly point out first terminal to discharge multimedia call.And for example, in communication network, can when inserting, each terminal require its reporting terminal capacity, the ability information of each terminal of network side preservation; When the multimedia call of receiving second terminal, can know whether second terminal supports multimedia call by the terminal ability information that the requester network side is preserved.
Though pass through with reference to some of the preferred embodiment of the invention, the present invention is illustrated and describes, but those of ordinary skill in the art should be understood that and can do various changes to it in the form and details, and without departing from the spirit and scope of the present invention.
