Technical field

The embodiment of the present invention is related to the field of computer networking；And particularly for registering visitor for online communication session Family calculates equipment.

Background technique

Many embodiments for providing online communication session (such as instant message, video conference etc.) require to calculate The user installation software of equipment and/or registration service.Therefore it is established and the online communication session of another user as user Prerequisite, two users must register and/or install identical software.Many embodiments also maintain that there are persons (presence) (such as list of friends), allow users to determine other users state (such as it is online, offline, leave Deng).

The large-scale public network of such as internet, frequently have to smaller private network connection, such as by company, because The private network that spy net service provider or even personal family maintain.Very especially (nature) due to them, Public network must have identical ideas to network address, the i.e. distribution of public address.For a variety of reasons, the guardian of private network Often private network's selection uses private network address, these addresses are not to the unanimous a part of distribution.Therefore, it is Network flow from private network can pass through public network, it is necessary to which some form of individual/public network address turns over Translate (" NAT ").

The equipment for executing NAT operation changes the data packet being sent to except private network with the addressing in accordance with public network Scheme.Especially, the public address of Network Address Translator own is replaced with assigned port number (port number) Change the port number of initial private addresses and Bao.Network Address Translator also changes the data packet received, so as to private network On computer replace purpose with the correct private addresses of intended recipient (intended recipient) and port number Ground public address and port number.As used herein, if be applicable within a context, term address should be by It is construed to include both address and port number, as understanding those of ordinary skill in the art.

NAT has become increasingly common in modern network calculating.An advantage of NAT is it with making public network The consumption in location space is slack-off.For example, the TCP/IP addressing used on the internet, includes four character strings, each character string three A number, therefore limited address space is provided.In addition, certain parts of this address space are preserved for special use Or user, further consume the actual quantity of available address.However, if using NAT, private network or sub-network can be with Using any number of address, but a standardized public address only still is presented to the external world.This makes available address The practically unlimited system of quantity, because it is the same private addresses that each private network, which can theoretically use for accurate,.

The advantage that NAT is provided is increased safety, this not can determine that from computer those of on public network The fact that actual (i.e. private) network address of private network upper computer.This is because being existed by Network Address Translator Public address is only provided on public network.In addition, this public address can be corresponding to the upper any amount of calculating of private network Machine.

Different NAT types use different security levels.For example, using " full cone NAT ", once one internally Location (iAddr:iPort) is mapped to an external address (eAddr:ePort), then any external host can be by that will wrap It is sent to eAddr:ePort and sends the packet to iAddr:iPort.It utilizes " restricted cone NAT ", address is the outside of hAddr Host, just can be by sending the packet to eAddr only after iAddr:iPort sends the packet to hAddr in advance: EPort and send the packet to iAddr:iPort.The port of external host is incoherent.It utilizes " port restricted taper NAT ", Address/port is that the external host of hAddr:hPort only sends the packet to hAddr:hPort's in iAddr:iPort in advance Under the conditions of, iAddr:iPort can be sent the packet to and sending the packet to eAddr:ePort.Finally, using symmetrical NAT, each request from the same iAddr:iPort to specific destination IP address and port are mapped to uniquely eAddr:ePort.If the same internal host sends the packet to different destinations, different external address and port are used Mapping.Only packet can be sent back internal host from the external host that internal host receives packet.

Reciprocity (" P2P ") calculates the distributed network structure for referring to being made of calculate node, these calculate nodes make one Partially their resource is supplied directly to other network participants.Compared with traditional client/server model, in P2P network Peer (peer) establish direct access communication channel each other and be not only used as and client but also be used as server, in traditional visitor Server supply resource in family-server model and client consume resource.

Above-mentioned NAT operation causes many problems of P2P connection.For example, if peer one or two of position Behind one or more above-mentioned NAT types, is then established between two peers and be directly connected to become further difficult.This Problem is aggravated due to following truth: such as Apple iPodApple AppleWith various other equipment (such as RIMEquipment, PalmEquipment etc.) client set It is standby frequently to be moved between the network with different NAT embodiments.For example, can Wi-Fi network (such as 802.11b, g, N network)；3G network (such as Universal Mobile Communication System (" UMTS ") network, High Speed Uplink Packet access (" HSUPA ") Network etc.)；It is communicated in blueteeth network (referred to as personal area network (" PAN ")).Following customer equipment will be such as Other communications of WiMAX, advanced international mobile telecommunication (" IMT ") and advanced long term evolution (" LTE ") (only listing several) It is communicated on channel.

Hands-free (hands-free) unit (such as headphone, automobile toolbox) is commonly used in and is used for hand-free service The same position of calculating equipment (peer).For example, for include cellular telephone function calculating equipment for, including be used as hands-free list The hands-free unit of sense of hearing relaying between member and calculating equipment is common with the ability of position.

In some embodiments, customer equipment 1210 and 1410 waits a certain amount of time from place's reception video frame each other, And if they do not exchange video frame on that time, take optional movement.For example, in some embodiments, video Calling is cancelled and cannot establish the message of video call and is displayed on the screen of customer equipment 1210 and 1410.For many Reason may not be able to establish video call, including bandwidth is not enough for video call, and video frame cannot be transmitted or be received Deng.It is objective in other embodiments although customer equipment waits a frame video before proceeding in some embodiments Many frames (such as stream of video frames) to be received such as in the given time period of family equipment before proceeding.

At block 1830 and 1832, customer equipment 1210 and 1410 is transferred to video call respectively.It is transferred to video call Including showing the video received and changing audio routing to video call from circuit-switched audio call.In some realities It applies in example, video preview (such as video preview 1310) is moved to the corner (and size reduction) of screen, and from peer The video received is revealed.It is therefore to be understood that until audio routing has been changed from circuit-switched audio call Video call is changed to, participant can be communicated by circuit-switched audio call (that is, circuit-switched audio call Still it is established, and video call is being negotiated).After being transferred to video call, circuit-switched audio call can be put It abandons.Therefore, process is moved respectively to block 1834 and 1836 from block 1830 and 1832, the circuit-switched sound at block 1834 and 1836 Frequency calling is abandoned.

The customer equipment 1210 and 1410 after being transferred to video call is shown respectively in Figure 15 and 16.Such as Figure 15 institute Show, customer equipment 1210 shows video 1510, and it is assorted that video 1510 is that the forward sight camera 1460 of customer equipment 1410 is capturing Video.Customer equipment 1210 also shows that video 1515, video 1515 are the views what forward sight camera 1260 capturing Frequently.GUI 1505 further includes terminating video button 1520 and end video and call button 1525.Terminate video button 1520 to permit Family allowable terminates video call and returns to only audio call.Terminating video and call button 1525 allows user thoroughly to terminate to regard Frequency calling (such as terminate talk) with the user of customer equipment 1410.As shown in figure 16, customer equipment 1410 shows video 1610, video 1610 is that video the forward sight camera 1260 of customer equipment 1210 be currently capturing.Customer equipment 1410 also show that video 1615, video 1615 are the videos what forward sight camera 1460 is currently capturing.GUI 1605 is also Including terminating video button 1620 and terminating video and call button 1625.

Figure 19 is shown according to one embodiment, is executed on the customer equipment that video call refuse information has been received The flow chart of exemplary operation.At block 1910, the reception of customer equipment 1210 video call refuse information be (customer equipment 1410 User has had rejected video call invitation).Process is moved to block 1912 from block 1910, and customer equipment 1210 shows video Calling is rejected message and optionally plays the one or more audio tones for pointing out to receive video call refuse information.Stream Journey is subsequently moved to block 1914, and customer equipment 1210 stops the video preview of display own at block 1914.If audio is defeated Speaker-phone is changed in block 1718 before out, then customer equipment 1210 can also prompt user back to initial sound Frequency output (such as passing through loudspeaker 1270).

Figure 20 is shown according to one embodiment, for being transferred to the customer equipment that circuit-switched calls from video call The flow chart of the exemplary operation of upper execution.Video call 2010 is established between customer equipment 1210 and 1410 (can basis Video call is established with reference to the mechanism of the description of Figure 17 and 18, or can not transfer and establish from circuit-switched audio call Video call).At block 1712, customer equipment 1210 receives the input that the circuit-switched for being transferred to only audio calls. For example, with reference to Figure 15, the user of customer equipment 1210, which has selected for terminating video button 1520, (such as terminates view by tapping Frequency button 1520 executes another prearranged gesture on terminating video button 1520).Customer equipment 1210 will then be pointed out to turn The message for being connected to the circuit-switched calling 2014 of only audio is transferred to customer equipment 1410.

Next customer equipment 1210 initiates the request of circuit-switched audio call to customer equipment 1410 (such as client sets Standby 1210 call many a customer equipments 1410 automatically).In some embodiments, this executes in the background and does not need user Interaction.Calling is carried out by many a network elements (such as base station, mobile switching centre etc.) of carrier network foundation structure Routing.

Customer equipment 1410 receives and answers circuit-switched calling 2020.In one embodiment, customer equipment 1410 Show access into call request and can playing point out into call request audio tones (such as Call Waiting tone or other Tone), and user's intervention is needed to carry out answer calls.In another embodiment, the automatic answer calls of customer equipment 1410 and No user intervention (and the audio tones pointed out into call request may or may not be played).After calling obtains answer, Only the circuit-switched calling of audio is established 2030 between customer equipment 1210 and 1410.

After only the circuit-switched calling of audio is successfully established, customer equipment 1210 and 1410 is transferred to only sound respectively The calling 2032 and 2034 of frequency.For example, the calling for being transferred to only audio includes changing audio routing to circuit from video call Switch type calling stops the video that display is received, and stops transmission video.Customer equipment can also stop showing video preprocessor It lookes at.It is therefore to be understood that although the calling of circuit-switched only audio is being negotiated, 1210 He of customer equipment 1410 user still is able to be communicated by video call (that is, video call is still established, and the only circuit switching of audio Formula calling is being negotiated).After the circuit-switched calling of successful handover to only audio, the knot of customer equipment 1210 and 1410 Beam P2P connection 2040.The user of customer equipment 1210 and 1410 can then be called by the circuit-switched of only audio and be carried out Communication.

Although about tool, there are two the video calls of participant to describe the embodiment of the present invention, embodiment is not It is so limited, because can have multiple participants in video call.In such an embodiment, customer equipment can be shown Show multiple video flowings of each different participant in Video chat.
