The application requires that under 35 USC 119 or 365 Britain of the submission of on June 14th, 2012 applies for the priority of No.1210596.1, and disclosure of the documents is all herein incorporated.

Background technology

There are a variety of communication systems for the packet-based speech or video call at scene are set up by the packet-based network of such as the Internet etc.For example, such system can use VoIP（Speech Internet protocol）Technology.A kind of communication system of popularization type is set up in equity（P2P）In topological structure.In traditional P2P systems, each end user is in his or she respective user terminal（Such as desk-top or laptop computer, tablet PC or hand phone）Upper installation communication customer end application program.Each user server registration then to P2P providers is so as to access authentication certificate.Some user terminals will also become the node of distributed data base, and user name of the user in P2P communication systems is mapped to the address of each the different user terminal in the network that the system is realized by which for which（Typically IP address）.Then, the communication between end user is carried out in the case of centralized server can be not related in call setup or verification process.On the contrary, one or more nodes of the client query distributed data base in the terminal of caller（Other end users being related in calling in any other manner（It is not necessarily themselves）One or more terminals）To determine the address of the terminal of expected callee.Caller and then address determined by use send calling to callee and invite, and callee receives response and responded to call.Caller and callee exchange their certification certificate so as to being authenticated each other.

Each user also maintains contacts list, and the contacts list can be stored on the server of P2P providers so that though it in the User logs in different terminals in the case of also can use.The profile information of other such as each users（Such as incarnation（avatar）Image or emotion message）Etc auxiliary information can also store on the server.Additionally, client application also exchanges existence information each other.The usability status of the existence information instruction user, and at least in part by user's himself or herself definition.For example, but whether existence can offline, online with instruction user be chosen to unavailable（" Do not disturb "）Or it is online and be chosen to can use.For example, each contact person that each client can be periodically polled in its contacts list is to determine their respective existence, and/or each client periodically can send out existence renewal to each contact person in its list.Existence will be typically based on P2P technologies and be sent with signal directly rather than via server between end user.When making a call, based on newest existence information, the client of caller determines whether callee can be used to receive calling.

Specific embodiment

With the increased popularity of the hand phone of the communication customer end application program that can run such as VoIP client etc, the end points that there is increasing number can be used to participate in the VoIP communication systems or packet-based communication system as other by the Internet etc. realization.But, a problem for being likely to occur is that typically with the resource more limited than conventional desktop or laptop computer, such as time per unit is able to carry out less process cycle to mobile phone telephone hand-set, there is less function per process cycle, with more limited memory resource（Such as RAM and/or caching）And/or with less screen area resource.Therefore, the operating system in some terminals（OS）Application-specific can be placed under background state.This can include communication customer end.Under background state, background application program can suspend completely, or to be unable to detect that the calling for coming invites and/or process the degree time per unit that traditional calling is invited to be scheduled limited process cycle.For example, this may be in the case where another application program be run just under prospect state, it is especially intensive in terms of process, memorizer and/or source of screen in other application programs, for example run on screen mode toggle or occur in the case that currently there are as leading application program certain other state.One example will be the computer game played on a cellular telephone.In this case, if client can not send out existence and update or the existence poll from other users is responded, then user may look like offline according to his or her existence.However, user may remain desirable to can be used to receive calling, for example would rather break of video game rather than missed call.Therefore, traditional existence concept starts to be broken.Similar problem may be potentially occurred in application-specific being placed under background state in any terminal of the feature for being beneficial to one or more other application programs.Accordingly, it may be desirable to the P2P methods being remote from for call setup, or be at least distally from pure P2P methods.

The speed of call signaling in another problem that the communication system of the conventional P2P systems such as realized on a packet-based network etc is likely to occur, especially how long to spend before calling is by response, or will spend and how long determine calling not by response.This is especially（But non-exclusively）It is probably a problem when the client of callee is under background state as discussed above, wherein caller may must wait the calling of attempt to invite overtime before his or she notified callee is unavailable.Call signaling postpones it can also happen that in other situations and in other kinds of communication system.

Accordingly, it may be desirable to be to provide a kind of improved or interchangeable mode that calling or other communication events are notified to destination user terminal.

The communication system of some other types notifies destination's user terminal of communication event using sending out notice.Sending out notice be server or another originate element instigating under rather than under destination terminal the instigating of itself（It is i.e. contrary with by destination's terminal pulling）From the notice that server sends.Therefore, sending out notice may be considered that asynchronous with destination terminal.For example, conventionally, such sending out notice can be used to indicate the IM from originating user terminal（Transit time flow meter）The availability of chat messages or file transmission at server.

However, in the past, " original " sending out notice only notifies that destination's terminal is present at server and waits its certain communication.Destination's terminal determines the property of its notified event, and pulls the property that is related to event for information about from server in response to receiving sending out notice in polling server is still necessary to the property to be communicated such as to determine.Thus, for example, it means that once destination's terminal receives notice, then and it is still necessary to allow whether destination user with regard to he or she wish obtain information that the communication make wise decision to obtain refering to server backward（If so, go back to fetch etc. to be communicated before this again, for example, fetch wait IM chat messages or file transmission）.

If for example such sending out notice system is directly suitable for informing the user calling invitation, so that original notify for waking up destination's client application from background state, then when waking up, destination's client then will have to polling server to find why it is waken up（Determine and be proposed calling）And it was found that allow it to invite calling the identity of the origination terminal or caller for being responded.This may be incorporated into undesirable delay in call signaling.

Additionally, obtain information property may still purposes it is limited, and not necessarily be adapted to the communication specific expected receiver or the communication specific sender or the combination of sender and receiver.

According to embodiments of the invention, there is provided a kind of amplification sending out notice mechanism, wherein sending out notice include payload, the payload is carried and enables destination user with regard to whether receiving to call or communicate to make the information of wise decision.Especially, payload information at least includes representing originating user --- the instruction of the image of the caller in the case of the speech for for example arriving or video call.

The image is properly termed as originating user（Such as caller）" incarnation ", and can be for example when other users watch the profile of the user from the server of VoIP providers or other communication providers in communication system for other purposes for representing the identical image of the user.

In embodiment, the instruction of described image includes the image itself being inserted in the payload of sending out notice, so as to receiver's terminal（The terminal of such as callee）Need not be it is determined that originating user（Such as caller）Identity before perform and fetch the additional call signaling of image.

In alternative embodiments, the instruction of described image can include the link of image, and the link allows destination's terminal to obtain image with minimum additional signaling.

Payload can alternatively include other information, such as instruction of the type of described communication（Such as calling, IM, voice mail, file transmission）；The additional instruction of originating user（Such as user name and/or display name）；For the language or language template of notice；The address of origination terminal；The instruction of the type of origination terminal；The encryption key of originating user；Timestamp；The Session ID of the communication session of proposal（The calling ID of the calling for example proposed）；For the talk identifier of communication；And/or the instruction of any repeater for communication.

In embodiment, as additional user information is provided in sending out notice itself, thus in the time for notifying, receive user can preferably determine whether he or she wishes to receive communication or the communication session of association（The calling for example proposed）.In certain embodiments, this not necessarily must be being realized in the case of fetching additional information from the network element of communication provider to determine the property of the communication of arrival and/or the identity of sender first.Which advantageously reduces the quantity of round trip and thus reduce signaling delay.

As mentioned, the modern mobile devices of such as hand phone etc can run communication customer end application program to will pass through the packet-based network of such as the Internet etc rather than only perform the packet-based communication of such as VoIP or other packet-based speeches or video call etc via the special cellular voice passage of mobile phone now.Using the ability, welcome online and can call or the number of users that can contact is sharply increased.But, the client application of such user is in when being likely to potentially be found in calling under background state, thus client is suspended, or at most the operating system of mobile device dispatches very limited amount of resource --- so as to need to be waken up to receive the calling of arrival.

Under such operating system system --- wherein application program no longer can ensure that can process in the background such as arrive calling, chat etc event --- framework of VoIP or other communication providers will benefit from extension.For example, this will be beneficial in a case where：Provider wants to call（And other）Notice is delivered to the user of their communication system, even if these users " backgrounds " relevant communication customer end application program（Or the application program is allowed by operating system background）, but which is still online even so and therefore can potentially call or can contact.The Call Block of client application can also be changed with the initial intention for guaranteeing calling party reliably can be delivered to wherein user should --- via sending out notice（If desired）Receive calling（Or other communications）All end points.

For example, it is contemplated that wherein callee is waiting his or her friend calls（Perhaps from foreign countries, therefore preference uses VoIP for cost reasons）While the service condition of web browser or playing video game is used just in enabled handheld phones or tablet PC.Whether callee is online based on existence status checkout friend, but when he or she is not online, callee starts to browse or play to fill up the time.Then, friend（Caller）Subsequently sign in the his or her client application on such as desk computer, be ready to call callee.In embodiment; the client of callee can be changed so that callee is shown as online to caller; even if the client application of callee due to due to browser or game need the high system resource for consuming for example due to due to the flash application programs that run in a browser or other applets is suspended or is suppressed by the operating system of callee.In an embodiment of the present invention, caller's click-to-dial button to be to initiate the calling with callee, and the operating system of callee is configured to eject to him or she the prompting of the calling for notifying to arrive.The client application of callee is configured so that if callee touches in response to prompting or clicks on accept button, then client application is brought back in prospect in the terminal of callee, so as to allow callee to calling（Speech or video）The friend or caller for carrying out response and starting with him talks.

There are some elements to be pointed out in the exemplary arrangement.The state of callee's client is potentially what is suspended completely in the worst case（Terminate）, and therefore will not be reached by conventional P2P session establishing methods.In an embodiment of the present invention, callee may be unaware that or notice that his or her client application is suspended, because this can not be explicitly completed by callee user --- it is in fact on the contrary, this may be automatically completed by operating system, and callee may assume that his or her client application still in operation, and they are online and can reach.Additionally, in this scheme, unlike the being conventionally present property mechanism of such system is used for, not so that existence is depended on（Or do not depend solely on）The P2P availabilities of client.

In order to support scheme above, there is provided business can realize new Call Block and/or make necessary change to existing part.

One target is to allow callee's client to wake up and can set up session with caller's client in reasonable time table and scope（Such as P2P sessions）.In order to be kept for the call setup time as short as possible, whenever possible, just the round trip in session and call setup should be remained at least.

As shown in the above example scheme, the service condition of the intention that stream can be supported to need calling is sent via non-P2P message transports system signal is initiated in calling, and this can return back to sending out notice in case of need to wake up callee's client.For example, the sending out notice service that this can be provided by means of the provider by the operating system for being discussed.

Call Block can be updated so that necessary client components change is for example realized in core library, to guarantee that they cater to institute service condition in need, interoperability and backwards compatibility scheme.

Calling customer end pieces can be updated and invited so as to the calling for allowing callee's client to receive the arrival received by means of sending out notice carrying method.This can include allowing client UI（User interface）The payload information of reception is transferred to Call Block, enables one or more UI that P2P session establishments and call setup and signaling carry out by layer API（Application programming interface）Set.

In order to calling is included in the payload of message of callee's end points is delivered to via message transport system for information about, call function can support the service based on cloud, and these services receive the message from conveying infrastructure and insert the specific payload information of the calling.

Call notification will include enough information to allow callee with regard to whether replying the decision that wisdom is made in calling.This can include such as caller's name（User name and/or display name）, caller incarnation and/or calling invite timestamp.Call notification can also include that the callee's client that allows of such as handshake information etc formulates the information for receiving response, and allow the information as response contact caller（Such as caller's user name and/or address）.

Once the call notification device of induction system completes the above, then transmit call notification to be finally delivered to callee's end points.This will be invited to the user of participation calling to receive in the case that sending out notice is registered or occurring in the case of arriving the open connection of client in presence.Notifying can be by directly persistently connecting（Callee's client is in the prospect and/or some background states）, or reach based on the notice service about operating system via sending out notice in case of need（Callee's client is suspended and/or some other background states）.

The invitation for participating in calling can be sent by MPTY in the case of some, and these situations are for example：Before actual call is set up, as the part initiated；Or during afoot calling, another participant is added to into calling.

Fig. 1 is the schematic diagram of the communication system based on traditional P2P normal forms.The communication system includes packet-based network 100, the wide area Internet network of such as such as the Internet etc（The Internet）.The communication system also includes multiple end user's terminals 102, and each end user's terminal includes the transceiver devices for being operable to be coupled to the Internet 100, and each end user's terminal includes the corresponding communication customer end application program of discussed communication system.Each in end user's terminal 102 can for example take desk-top or laptop computer, tablet PC or hand phone（Or " telephone hand-set "）Form.Each in user terminal 102 is the potential end points of the voip call in communication system or other packet-based communications.That what is illustrated in Fig. 1 is caller's end points 102a and callee end points 102b.

According to conventional P2P principles, the client application in one or more in user terminal 102c is presented the state of the node in distributed address searching data storehouse.In order to determine the address of the user terminal 102b of callee（For example include IP address）, the client at step S10 on the user terminal 102a of caller is via the client communication on one of the Internet 100 and the user terminal 102c for the node for serving as distributed data base.Client in terminal 102a of caller inquires about database node 102c by the user name of the callee to the callee in database node 102c transmission identification communication systems, and database node 102c returns the required address of the user terminal 102b of callee.At step S12, then the client in caller party terminal 102a sends call setup request or " invite " to the client signal in terminal 102b of expected callee using the address（CI）.As response, if callee selects to receive calling, then the client in callee's terminal 102b sends calling with signal backward and receives response.Client in terminal 102a and 102b of caller and callee also exchanges certification certificate to verify mutual identity.These clients hence set up between session so that the traffic of the Real-time voice and/or video content form of mike and/or video camera on its each self terminal 102,102b is sent as a part for live voice or video call.As address search is based on distributed data base, thus it is not necessarily related to the central server for this purpose.Call setup signaling, certification and call communication amount are also carried out in the case where being related to central server.

In embodiment, if the user terminal 102a of caller is due to NAT（Network address translation）Or directly can not communicate with the user terminal 102b of callee the reason for fire wall 108, then these clients can be configured to one or more repeater communications realized via the client that can also be run in end user's terminal 102d by one or more other users in P2P communication systems.The user of relaying end user's terminal 102d needs not to be the participant of calling（The speech or video content of calling need not be consumed, and really can not due to due to encryption）.Even so, the user of relaying end user's terminal 102d agrees to when he or she is signed in P2P communication systems as situation, and himself or herself can benefit from reciprocal arrangement in other cases.

Communication system may further include the back-end server 104 for being coupled to the Internet 100, wherein each in the client can store respective contacts list, the list is the list of its respective contact person of user（Communication system is configured so that user becomes the contact person of mutual agreement）.Back-end server 104 can also store the profile information for each user, such as the avatar image to the other users representative correspondence user in communication system.Each client can access and show the profile of contact person so that caller can see that the profile information of callee, and vice versa.

Communication system can also include being coupling in the Internet 100 and circuit-switched network（It is not shown）Between gateway 106.Such network can be referred to as PSTN（PSTN）, such as land line network, or the such as mobile cellular network of 3GPP networks etc.Thus client on user terminal 102 also can set up calling with more conventional phone via gateway 106.

Fig. 2 illustrates the mixed P 2 P communication system of the modification according to the embodiment of the present invention.The some or all parts of Fig. 1 still can also be present with the system in parallel of Fig. 2, but some parts are omitted from Fig. 2 for brevity.Additionally, communication system includes communication service provider（Such as VoIP providers）, be coupled to the Internet 100 and be configured to run Call- Control1 and notify software one or more server units form network element 204.Communication system also includes one or more the sending out notice services based on operating system for being coupled to the Internet 100（OS PNS）202.Each in one or more of sending out notice services 202 based on operating system is associated with corresponding operating system, and the manufacturer by operating system and/or publisher are provided to support via the available special sending out notice mechanism of the operating system for being discussed.The form of one or more server units for being configured to run sending out notice software is taken based on the sending out notice service 202 of operating system.

In the example system of Fig. 2, it is illustrated that element 102,202,204 be configured to following operation.At step S20, the client on the user terminal 102a of caller will be called and be invited（CI）The client not being sent directly on the user terminal 102b of callee, and it is sent to the Call- Control1 and notification element 204 of VoIP providers（Message CI is not necessarily identical with regard to the message described by Fig. 1）.At step S22, the calling in response to receiving from caller is invited, and the Call- Control1 of VoIP providers and notification element 204 generate it and send to the sending out notice request of the sending out notice service 202 based on operating system（PNR）.At step S24, the sending out notice in response to receiving from VoIP providers 204 is asked, and the sending out notice of operating system services 202 by the sending out notice based on operating system（PN_OS）Send the operating system to the user terminal 102b of callee.Sending out notice based on operating system is received and processed by the operating system on the user terminal 102b of callee so that it shows to callee user on the screen of the user terminal 102b of callee the Pop-up message for indicating the event that there is arrival.

In an embodiment of the present invention, on screen, message can point out whether callee receives the calling for arriving.If the client application of callee is currently background, then on screen, message can prompt the user whether from background state the client application for waking up callee.In embodiment, can be by these combination of actions in identical prompting.If as response, callee provides user input in mode certainly, then operating system wakes up callee's client application by rescheduling enough resources of the calling of the callee's client application dispatch deal in the terminal 102 to complete operation level or at least to callee.

As hereinafter discussed in more detail, in embodiment, any one server during sending out notice PN_OS can include enabling client on the user terminal 102b of callee directly by the Internet 100 rather than via provider or box service element 202 and 204 formulates the payload of return handshake information and signal, and the return handshake information and signal notice the client on the user terminal 102a of caller backward by the Internet 100.If callee receives to point out from the user of operating system, then at least a portion of the payload of sending out notice is passed up to the client application of callee so that it can formulate relevant response and send the response to caller backward by the operating system on the user terminal 102b of callee.

Fig. 3 illustrates the mixed P 2 P communication system of another modification according to the embodiment of the present invention.The some or all parts of Fig. 1 and/or Fig. 2 are likely to still to be present with the system in parallel of Fig. 3, but some parts are eliminated from Fig. 3 for brevity.

In the example system of Fig. 3, it is illustrated that element 102,204 be configured to following operation.At step S20, calling is similarly invited by the client on the user terminal 102a of caller（CI）The client not being sent directly on the user terminal 102b of callee, and it is sent to the Call- Control1 and notification element 204 of VoIP providers（Message CI is not necessarily identical with regard to the message described by Fig. 1）.In embodiment, this can be that or in other embodiments, it can be independent step alternatively or additionally with regard to the identical step of the step described by Fig. 2.However, in this case, VoIP providers element 204 does not send（Or not only send）Sending out notice is asked（PNR）To the sending out notice service 202 of operating system.On the contrary, it directly formulates the application layer sending out notice of its own（PN_AL）, the application layer sending out notice is sent the client to the user terminal 102b of callee by the Internet 100 directly for it.Client on the user terminal 102b of callee and then can be in the application layer process notice so that oneself is by means of application layer mechanism rather than the call prompt callee user that just arrives of operations described above system mechanism.

As hereinafter discussed in more detail, in embodiment, any one server during sending out notice PN_AL includes client on the user terminal 102b for enable callee directly by the Internet 100 rather than via provider or box service element 202 and 204 formulates the payload for returning handshake information and signal, and the return handshake information and signal notice the client on the user terminal 102a of caller backward by the Internet 100.In this case, if the client in terminal 102b of callee is under prospect state（It is not suppressed to be beneficial to any other application program）Or in wherein its scheduled limited cycle but under the special environment state of the calling that still be enough to process arrival, so the client of callee can by the time of the client that callee is dispatched in operating system during intercept come the communication of the arrival of automatic network 100, for example callee terminal 102b the client being allocated for for callee using web socket on intercept and directly access the payload of sending out notice.

It should be pointed out that two or more in the mechanism of Fig. 1, Fig. 2 and Fig. 3 concurrently can be present, and in these mechanism any one or all can be used for sending calling with signal and invite or notify.

In one embodiment, at least callee's end points 102b includes mobile terminal, and the mobile terminal has relatively limited resource（Process, memorizer and/or source of screen）, and with being easy to the operating system that the corresponding client application of backgroundization is beneficial to another application program of video-game such as in some cases etc.In the case that client application is suspended completely wherein, it means that it is terminated, until waking up, and cold start-up may be needed to receive calling or other communications.

Fig. 4 gives two end points to form calling（Or or even the greater amount of end points in Multi-Party Conference calling scheme in two）Calling party（Caller）Originate end user's terminal 102a and called party（Callee）Destination's end user's terminal 102b schematic block diagram.

Originating user terminal 102a includes the communication customer end 402a of corresponding operating system 400a, VoIP communication system（And potentially also have other application programs）With user interface 408a.VoIP client 402a is stored in origination terminal 102a（The computer-readable memory or form of medium of such as electronics or magnetic storage apparatus etc）On memorizer, and it is arranged for performing in the processing meanss of origination terminal 102a.Term " computer-readable memory " is intended to all legal form for covering storage medium, and therefore is not intended to cover the non-legal form of medium of such as signal and carrier wave etc.

Client application 402a is also referred to as running in operating system 400a, because it is scheduled for being performed by operating system 400a.Exist and run on the application program in terminal 102a if there is multiple, so operating system will dispatch them to perform for example in a staggered manner and/or on parallel processing resources so that each application program is allocated at least some process resource under the control of operating system 400a.When scheduled, client application 402a can be communicated by network 100 via transceiver devices of the user interface 408a with user mutual and via user terminal 102a.As will be discussed in more detail with regard to destination's terminal 102b, operating system can also suspend the execution of the application program of such as client application etc.

Destination user terminal 102b also includes communication customer end 402b, the such as other application programs of email client 404 and video-game 406 etc and the user interface 408b of corresponding operating system 400b, VoIP communication system.Communication customer end 402b is stored in destination's terminal 102b（The computer-readable memory or form of medium of such as electronics or magnetic storage apparatus etc）On memorizer, and it is arranged for performing in the processing meanss of destination's terminal 102b.VoIP client application program 402b and other application programs 404,406 are referred to as running in operating system 400b, because they are scheduled for being performed for example in a staggered manner and/or on parallel processing resources by operating system so that each application program is allocated at least some process resource under the control of operating system 400b.When scheduled, VoIP client 402b can be communicated by network 100 via transceiver devices of the user interface 408b with user mutual and via destination user terminal 102b.When the other application programs 404 and 406 are scheduled, situation is same.

As mentioned, operating system 400b can also have and suspend the application program of such as VoIP client 402b etc or be placed on the ability that wherein its time per unit is only allocated under certain other background state of very limited amount of process resource.

In embodiment, the scheduling of operating system 400b include for each application program 402b, 404,406 being placed in prospect state or background state under ability.

Prospect state can include that wherein prospect application program is main, leading application program the state run in current time.One particular instance of this point is that application program is run under screen mode toggle, and in this mode, it is allocated whole source of screen by cost of other application programs.For example, video-game 406 can operationally be given full frame or other leading prospect states, because user may need it is full frame may consume significant process resource to play game and/or play, consequently, it is possible to so that limited process resource or not having process resource to can be used for the other application programs of such as VoIP application programs 402b and email client 404 etc.This scheme is particularly likely to be occurred on the mobile terminal of such as hand phone etc, and at the mobile terminal, resource is relatively limited compared with such as desk computer.

Another example of prospect state can include such state, none of which application program has dominant state relative to any other application program, for example, the user of terminal 102b has the open desktop computer that no application program is maximized, and operating system 400b allows VoIP application program 402b to have enough process resources to carry out complete operation, be not inhibited any other application program for being beneficial to such as video-game 406 etc.

However, when the application program of a such as video-game 406 etc is under leading prospect state, one or more other application programs 402b, 404 can be placed under background state by operating system 400b.VoIP client 402b can be the particular candidate put for this.Alternatively or additionally, in other times, operating system 400b can be placed under background state the application program of such as VoIP client 402b etc to save battery resource.

Under such background state, VoIP client 402b or it is suspended, it means that it is not dispatched any process cycle by operating system 400b, or is at most suppressed so that it is only scheduled the limited cycle compared with non-inhibited prospect state.Under inhibitory state, client 402b may only have very limited amount of function, wherein it may not unilaterally process calling invitation or the notice of arrival, or may not be using available full resource process calling invitation or notice under higher functional statuses in other cases.

Under prospect state, VoIP client 402b is fully able to invitation or the notice for intercepting arrival, and it completes this point by intercepting on the web socket 412 of destination user terminal 102b.Web socket is the combination for being assigned to the transport layer port and network address used for the application program of such as VoIP client 402b etc, and typically, IP sockets are the combination of IP address and port numbers.For example, under prospect state, VoIP client 402b directly may receive conventional P2P callings from origination terminal 102a and invite（CI）, and the invitation is correspondingly processed to receive calling, and/or may can receive and process the application layer sending out notice from VoIP providers 204（PN_AL）.Destination's client 402b can allow persistently connection for this purpose for the network element 204 of provider is opened.

In embodiment, under background state, the cycle that VoIP client 402b is not dispatched, and the sending out notice service 202 based on operating system is necessarily dependent upon, or anything in addition to the sending out notice based on operating system is serviced is cannot rely upon with the too limited cycle.In this case, the sending out notice based on operating system（OS_PN）Received by operating system 400b, pointed out on display screen in destination's terminal 102b as the operating system is responded.The prompting notifies that callee has the communication event that request notes, and prompts the user to choose whether to exit screen mode toggle or otherwise allow to wake up the application program of one or more dormancy.The form of onscreen cue can be determined by operating system 400b, alternatively with a small number of parameters that can be specified in sending out notice.In certain embodiments, the prompting can inform the user the fact that only exist unspecified communication event, and generally ask whether from full frame or holding state morning call.In other embodiments, the prompting can include that some permission users make the additional information of the decision of wisdom, and such as communication event is the instruction of the calling for arriving, and/or be related to the user of caller identities and may be viewed by information（Such as display name and/or avatar image）.Such additional information can be derived from the payload of the sending out notice for receiving.

In addition, if user receives, the derived customizing messages from sending out notice payload can be passed up to the application program 402b for waking up by the appropriate API 410 so between operating system 400b and VoIP client 402b so that VoIP client 402b in destination's terminal 102b can be formulated response and the response is returned origination terminal 102a backward.The payload information can include machine-readable identification symbol information, such as address of terminal 102a of the caller in the user name and/or identification network 100 of the caller in identification communication system.

In alternative embodiments, there may be the background state of VoIP client 402b, wherein it is dispatched the limited cycle by operating system 400b, but these cycles still be enough at least to intercept the application layer sending out notice on socket 412 and the notice to receiving performs at least certain process, potentially even receive response and origination terminal is returned it to before wake-up to formulate（Although may still need wake-up practically to be called, i.e., the speech and/or video flowing for once arriving and going out starts, then process these streams）.

Using the sending out notice service based on operating system, notice be sent to operating system 400b and it is at least initial when by operating system process（Even if at least some in payload is subsequently passed up to application program 402b by operating system 400b）.This is notified different from application layer, wherein operating system 400b dispatches at least some cycle to application program 402b, and these cycles application program enough is intercepted about the sending out notice on socket and at least certain process is performed in the case where any special sending out notice mechanism of operating system 400b is not relied on to the notice of reception.

Call- Control1 and the schematic block diagram of notification element 204 of the Fig. 5 there is provided the VoIP providers according to an example implementation of the invention.Network element 204 includes：Call controller 502, is coupled to the missed call Register 504 of call controller 502, is coupled to call controller 502 and the sending out notice service based on operating system（OS PNS）202 sending out notice center 506, pushes enabled endpoints（PEE）Register 508, is coupled to the parser function 510 of call controller 510, and for caller's client 402a in originating user terminal 102a to be coupled to the connection adaptor 512 of call controller 502.Each in element 502,504,506,508,510,512 can be implemented as being stored in one or more server units of VoIP providers 204（The computer-readable memory or form of medium of such as magnetic or electronic storage device etc）On memorizer and it is provided in the software module run on one or more of server units of VoIP providers 204.One or more of server units include being configured to the processing meanss for performing the software and are configured to perform communicatory transceiver devices by packet-based network as the Internet 100 or other.

Destination user terminal 102b can be registered as pushing enabled endpoints（PEE）, and callee's client 402b in destination's terminal 102b can be configured to one or more the application layer sending out notice from sending out notice center 506 are received via IP sockets 412（PN_AL）, and/or operating system 400b can be configured to receive from the service 202 based on operating system one or more sending out notice based on operating system（PN_OS）.In the later case, callee's client 402b in destination's terminal 102b can be configured to receive from the sending out notice based on operating system via API 410（PN_OS）In the payload information of one or more.

In operation, VoIP client 402a of the caller in origination terminal 102a is started by being connected with the formation of call controller 502 via the Internet 100 and connection adaptor 512.The connection can provide discernible connection so that be identified as coming from specific known source from any communication of caller's client 402a by the given connection reception with connection adaptor 512 by call controller 502.Connection adaptor 512 can be with the identity of authenticated calling person so that any communication received by the connection with connection adaptor 512 is all identified as coming from the source that its identity is securely authenticated.

In embodiment, connection adaptor 512 provides front end component, and the front end component uses appropriate authentication mechanism（Which can be proprietary）Terminate the connection of client to client certificate and also.Connection adaptor 512 is in the authority source that may be used for the client identity for remaining service and especially call controller 502（Referring to later discussion）.In embodiment, therefore, it is not necessary to be provided the identity of caller by caller oneself in payload, this is favourable, because otherwise identity may be forged and thus be not trusted.

In step S20 and/or step S30（The step of to shown in Fig. 2 and Fig. 3, is corresponding）Calling is invited using the connection by place, client 402a on the user terminal 102a of caller via connection adaptor 512（CI）Send to the call controller 502 of VoIP providers 204.

In order to set up for carrying out the session of the such as communication of calling etc, it is necessary to exchange and form two handshake protocol messages of two halves shaken hands --- first from an end points to another end points, and and then second handshake information agree to calling as return.In embodiment, the calling sent from caller's client 402a is invited and includes the first handshake information HS1.

In embodiment, HS1 can be P2P session establishment message.In this case, its recipient comprising the message can continue to the enough information for consulting P2P transmission sessions with sender（For example can be used to be called）.It can include one or more and can reach the IP address and potentially some other information of caller by which.The message is used as the invitation for setting up P2P sessions.Once establish certification and encryption session, then call signaling can be flowed by the session.Repeater information and user name are certain things detached with HS1, and when HS1 is unavailable or when expiring while advancing, they can be used in fallback mechanism.It should, however, be mentioned that these embodiments are not limited to P2P or mixed P 2 P arrangement, and in other embodiments, some or all in the follow-up phase of session establishment can be carried out via the centralised element of such as one or more servers etc.Other kinds of session establishment agreement for setting up other kinds of communication is also possible.

Then, the calling in response to receiving from caller's client 402a is invited, and call controller 506 formulates internal sending out notice request PNR_i.

In embodiment, this is related to the call controller 502 at step S50 and quotes parser function 510 to parse the identifier information of caller and/or his or her user terminal 102a --- " user's parsing " information（UR）.Resolver 510 maintains user and/or user terminal list of relevant information, and call controller 502 can be based on the list of the Connection inquiring of identification and connection adaptor 512.

User parses（UR）At least two classifications can be fallen into.First classification is the identifier information of caller will to be contacted for client 402b for allowing callee as response.This can include：

Caller's user name of the caller in identification VoIP communication systems；And/or

The address that the user terminal is recognized in network of originating user terminal 102b of caller（Typically IP address）；And

Alternatively additional routing iinformation, such as contacting any one or more repeaters of caller（Such as 102c）Mark.

Second classification of UR information is to allow callee with regard to whether replying the information that wise decision is made in calling.This can include：

The display name of caller（It is different from user name）；

Represent the image of caller（Which is properly termed as " incarnation " image）；And/or

For the instruction of the language of the calling for arriving is notified to callee, its by when manifesting at terminal 102b of callee its can expand to the language template specified for the syntax of notification message on screen.

According to embodiments of the invention, the UR information being inserted in the payload of sending out notice includes representing caller（Or more generally for originating user, i.e. origin endpoint user）Image.For this purpose, resolver 510 includes the data base of the presentation graphics that the identity of the multiple users against the communication system for being discussed is drawn.Then, resolver 510 is configured to instruction of the identity resolution based on caller about image, and the image is inserted into payload（Or alternatively, it is possible to the link to image accessed by callee when notifying）In.

In one or more embodiments, image is avatar image, and which is generally with also by caller（Or originating user）In the communication system for being discussed（For example in VoIP system）The image for being broadly used for representing themselves is substantially the same（For picture material）.For example, avatar image can also be accessed from the server 104 of communication provider by callee or other contact persons.The resolver 510 of element 204 can be integrated with the back-end server 104 for providing profile so that resolver 510 access user in other cases generally the profile of interrogating call person when the same instance of image that accesses（Identical copies）.Alternatively, resolver 510 can be configured to the different instances for accessing identical image（The different copies of identical content）.In embodiment, no matter which kind of mode, the example being such as inserted in payload can be the reduced size of example of image（For size on bit and/or screen）.

In embodiment, resolver 510 further includes the list of the nationality, residence and/or language that the identity of the multiple users against the communication system for being discussed is drawn.Then, resolver 510 is configured to the identity resolution language based on callee and/or caller or language template.The identity of caller（Such as user name）Calling can also be included in invite（CI）In, and can be used for this purpose and identifying purpose ground.In one or more embodiments, the language of selection（And alternatively language template）Based on callee（Or more generally receiver）Nationality, language and/or residence and be chosen because this is described to notify that informant is wanted in expection.If however, this is unavailable, then optimal conjecture can be that callee or receiver understand caller（Or more generally sender）Language.

In certain embodiments, resolver 510 is configured to the identity based on both caller and callee and by determining the common language of the two users come analytic language or language template.

In embodiment, parser function 510 can also include License Check function, and the License Check function maintains callee to stop its his or her user list of contact.License Check effect is invited come the calling for stopping any caller found in the list, and for notifying that the following steps of callee are only just carried out under conditions of caller is not blocked.

Assume that this does not occur, then call controller 502 is formulated includes that user's parsing information, HS1 message and calling are invited（CI）Any other payload for information about of middle reception（See below）.Then, at step S52, the payload is forwarded to into sending out notice center 506 in the PNR_i of sending out notice request internally of call controller 502.

The additional information that may be embodied in payload is as follows.

Instruction sends the timestamp of the time of invitation.This can be used to the attempt time-out for detecting when to set up calling.For example, may be in the range of the 30-60 seconds for the overtime time limit, and be 50 seconds in one embodiment.Timestamp is may be embodied in calling invitation, and the calling is invited from caller's client 402a and sent, and is then forwarded in payload, or is generated by call controller 502 in the case where not yet including from the invitation of client 402a for being received from caller.

The encryption key of key exchange scheme, which is the public keys of caller（Thus callee can decrypt the content of caller）.This is may be embodied in calling invitation, and the calling is invited from caller's client 402a and sent, and is then forwarded in payload, or is alternatively stored at resolver 512 and is parsed another example of information as user and added by call controller 502.

The instruction of the type of origin endpoint 102a（For example it is mobile phone, tablet PC, laptop computer or desktop computerIt runs any operating systemIt runs VoIP client 402a of what version and/or it are what models）.Again, this is may be embodied in calling invitation, and the calling is invited from caller's client 402a and sent, and is then forwarded in payload, or is alternatively stored at resolver 512 and is added as the part of parsing by call controller 502.

For the Session ID of calling, which can be added by client 402a of caller or call controller 502.Again, this is may be embodied in calling invitation, and the calling is invited from caller's client 402a and sent, and is then forwarded in payload, or is alternatively stored at resolver 512 and is added by call controller 502.

Talk title and/or other talk identifiers for calling, it is for example the instruction that calling is part thereof of logic theme or context in the case where the part for forming the more extensive talk for being related to IM message and/or previous calls is called.This calling that can take from client 402a from caller is invited.

If notice system can be used for different types of communication（In addition to speech and video call, such as IM message, voice mail and/or file are transmitted）, then payload can also include the instruction of communication type.

Sending out notice center 506 receives internal sending out notice request PNR_i.At step S53, as response, it inquires about and pushes enabled endpoints（PEE）Register 508 is to check whether callee has registered to receive sending out notice.PEE Registers 508 maintain to have registered to receive sending out notice（Or receiving sending out notice in the case of default, equivalently no cancel register is in order to avoid receive sending out notice）User list.For example, this can be that the when option of the new phone 102b of his or she initial start-up, or the option found in the option screen of his or her terminal 102b is presented to user.Subsequently, when as in the scheme for illustrating attempting to be called, PEE Registers 508 act to only permit in callee, following sending out notice step agrees to that his or her equipment 102b is possible to receive sending out notice（Or equivalently do not determine to exit）Under conditions of carry out.

Assume that callee is registered for sending out notice, then do in two pieces thing or two pieces in sending out notice center：

PNR is asked to send to the sending out notice service 202 based on operating system outside sending out notice（It is corresponding to S22 the step of Fig. 2）, this in turn results in the sending out notice based on operating system and services 202 by the sending out notice based on operating system（PN_OS）Send operating system 400b to destination's terminal 102b（It is corresponding to step S24 in Fig. 2）；And/or

Formulate application layer sending out notice（PN_AL）And send it to client 402b of the callee in destination's terminal 102b（It is corresponding to step S32 in Fig. 3）.

Additionally, at step S53, sending out notice center can will indicate the message of the end points quantity of callee backward（NEP）Send to call controller 50（Callee may be with the multiple equipment registered to PEE Registers 508）.This can be used for tracking the attendance report that can potentially expect how many equipment from callee by call controller（AR）（Referring to step S56）.

Sending out notice center 506 acts on and at least some being received from the payload information of call controller 502 is included in sending out notice（In the case of the sending out notice PN_OS based on operating system, via OS PNS 202）.In embodiment, the quantity of payload information can be by sending out notice center 506 according to the type that the information is contained in sending out notice therein（The operating system of being also based on based on application layer）Selected.

Sending out notice center 506 formulate application layer sending out notice in the case of, this can include any amount of payload information, until and including discussed above total or more.This can include the first handshake information HS1 of Handshake Protocol and until full user parses information（UR）Anything, user name, originating address, the display name of caller including caller, for the avatar image of caller（Or to the link of avatar image）And language indicator or template.The payload information is provided to callee's client 402b in application layer sending out notice PN_AL.

If client 402b in terminal 102b of callee receives application layer sending out notice PN_AL, then the calling that it extracts payload information and notifies to arrive to callee using the information.This can include extracting user's readable portion that user parses information, such as display name, avatar image and/or language template, and generate appropriate user's notice of notification message form on screen using it.For example, on screen, message can illustrate avatar image and display format is the written message of " you have the calling of the arrival from [display name] ".Alternatively, user notifies the form of the audible spoken message that can take the speaker from destination's terminal 102b.

The language of user notification message（In other words, written or spoken language, i.e. feel for the language language）Determined based on the instruction received in the payload of sending out notice.For example, this can from including two or more groups in following appointed language：English, French, German, Dutch, it is Spanish, Portuguese, Italian, Greek, Romanian, Hungarian, Bulgarian, Czech, Polish, Swedish, Finnish, Norwegian, Estonian, Latvian, Lithuanian, Ukrainian, Russian, Turkish, Arabic, mandarin, Guangdong language, Japanese, Vietnamese, Korean, amoyese, Thai, Hindi, Urdu, Bengali, Punjabi, horse traction ground language, Telugu, Pushtu, Javanese, Afrikaans, sign language etc..

In an embodiment of the present invention, the syntax limited based on the language template received in the payload of sending out notice by the form of user notification message is determining.During at least one function of syntax refers to attribute sentence（Or more generally, in the part of text or voice）Including the position of display name.Other language formatting information can also be included in syntax, and for example the instruction of the communications event type for arriving is placed in where（Calling, voice call, video call, IM, voice mail, file transmission etc.）.

For example, in English, user notifies to take form " you have an incoming call from [display name] ", ending of the name of caller or sender in sentence, and in French, for example it can take form " [display name] vous t é l é phoner ", the name of caller or sender to be in the beginning of sentence.The position that name is inserted in character string can be the function of the language that resolver 510 is selected, and therefore syntax is corresponding to language.Language and syntax（That is language format）Specified by language template.

In addition, assume callee's response calling, client 402b so in terminal 102b of callee is configured to from the payload of sending out notice the session establishment information for extracting such as handshake information HS1 etc and the part for information is parsed as the user of response contact caller, and receives response so as to formulate calling（CA）And the response signal is sent originating client 402a to terminal 102a of caller backward.Calling receives the foundation that response receives session, it is intended that called using the session.For example, after receiving HS1, client 402b of callee is formulated calling and receives response CA, and the calling receives response includes half response of Handshake Protocol, HS2 message.Then, at step S58, the acceptance response signal is sent client 402a to origination terminal 102a by the relevant user parsing information of client 402b of callee based on the address of terminal 102a of the user name and/or caller at least including caller backward.

By using payload information, this without the need for before he or she decides whether response calling by any other signaling of network 100 obtaining for contacting the identifier information of terminal 102a of caller, or to obtain and recognize caller to callee and/or complete in the case of determining the information of form that user notifies.For present purposes, without the need for backward for the extra reference of such as any provider of element 204 or 202 etc or carrier infrastructure.Therefore, in call signaling, the quantity of round trip is reduced, it means that for realizing that the time that calling receives can be reduced.

In embodiment, client 402b of callee can be in prospect in its time for being found in notice（f/g）Application layer sending out notice PN_AL is only received in the case of state, because in this state, it has scheduled enough process cycles, can intercept on IP sockets 412 and application layer sending out notice PN_AL is processed when detecting.But, in some implementations, it is possible to which client 402b of callee may be allocated the special environment state, although the process time of suppressed quantity wherein it is scheduled, but it still has enough cycles, can detect and act on application layer sending out notice PN_AL.

To rear report to call controller 502, client 402b of callee can also indicate that it has received the attendance report of calling at step S56（AR）.Whether call controller 502 can be using this report tracking calling by response, or whether calling is overtime before which is by response.Alternatively, attendance report（AR）Can be sent by the originator when originator is received from the response of destination.Latter option can be used in a case where：Call in destination side by not using the old edition client response of the function renewal for sending attendance report.

In the case where the sending out notice PN_OS based on operating system is generated via service 202, this can include the payload information that the quantity among potential payload information discussed above is reduced.For example, this can include user's parsing information of handshake information HS1 and some selections（UR’）, at least address of the user terminal 102a of the user name of caller and/or caller.If the form for notifying allows picture coding of enough bits to moderate size, then avatar image can also still act as the payload information in the notice based on operating system.The payload information is provided to operating system 400b in destination's terminal 102b in the sending out notice PN_OS based on operating system.

If operating system 400b in terminal 102b of callee receives the sending out notice PN_OL based on operating system, then on its generation screen, message is so as to the calling arrived to callee's notice.Alternatively, this can be related to some limited parameters that the payload information from message on the predefined screen for be inserted into operating system 400b is extracted.For example, the display name that operating system 400b can determine caller according to the payload for receiving, and the presentation graphics of caller are received, and these can be inserted in the predetermined format notified on screen.However, on screen message format other in terms of can be determined by operating system 400b, the figure of such as its size, its " perception " and any association.

For example, if callee playing video game 406 or uses certain other application program in the time of notice just under full frame or dominant state in the case of other, then operating system can cause little notification message in the relative background ejection of such as corner screen etc.

Whether on the screen that operating system 400b of callee is generated, message notifying callee takes any action, for example whether answering calling, or refuse to notify and continue play under game 406.

As discussed previously, destination's VoIP client 406b can be in background in the time of the notice for arriving（b/g）Under state.If in response to operating system is pointed out, callee selects to receive calling really, then operating system wakes up VoIP client 402b of callee.This can be related to the application program for terminating previously to have run under prospect（406 are played for example）Dominant state full frame or as other.

At least a number of payload information is also passed up to operating system 400b in terminal 102b of callee VoIP client 402b of new recovery, transmit the first handshake information HS1, and at least some in the user's parsing information as response contact caller, i.e. caller's user name and/or origination terminal address.When callee's VoIP client 402b wakes up, it receives response CA and the originating client 402a that be backward sent to the response user terminal 102a of caller on including the calling for returning handshake information HS2 therefore, it is possible to formulate.

The payload information that receives in sending out notice thus still be enough to without the need for he or she decide whether should before calling by any other signaling of network 100 to obtain the information that caller is recognized for the identifier information or obtain to callee for contacting terminal 102a of caller in the case of formulate calling and receive response（CA）.Therefore, similarly, the quantity of round trip and thus be accordingly used in calling receive time can reduce.

Again, to rear report to call controller 502, client 402b of callee can also indicate that it has received the attendance report of calling at step S56（AR）.Alternatively, attendance report（AR）Can be sent by the originator when originator is received from the response of destination.Whether whether call controller 502 can overtime before which is by response by response or calling using this report tracking calling.

In certain embodiments, concurrently existed based on application layer and based on operating system both sending out notice mechanism.Both Notification Methods can concurrently be attempted in sending out notice center.

Additionally, caller's client 402a in originating user terminal 102a still can be operable to directly invite conventional P2P callings by the Internet 100（CI, step S10）Send callee's client 402b to destination user terminal 102b.

In alternative embodiments, HS1 can not be included in the calling invitation from callee（CI）In（Step S20/S30）.HS1 is sent to caller in response to initial notification on the contrary, exchanging and may require callee, and then caller is replied to set up reverse session using the second handshake information HS2.

In embodiment, once performing call signaling above, then the certification of user can be carried out in the way of mutual by exchanging certificate between callee and caller as in routine P2P modes.Alternatively or additionally, when connection adaptor is when the identity of time verifying caller of initial connection is formed, certification can be intensively performed by connection adaptor.In the case of certification is completed by exchange certificate after superincumbent signaling wherein, it should be noted that, it is not an absolute ultimate criterion for being used to successfully be called that calling receives response CA, but the interim acceptance of session is set up, and certification can be carried out by which first --- and actual calling is affected by the certification（As long as communication is not malice, then this unlikely becomes problem in most of situations）.In other embodiments, certification may depend only on connection adaptor for the initial authentication of caller.

In some embodiments it is possible to the two stages of certification are used during session is set up.First, caller's client in connection adaptor 512 certification oneself and and then by set up the transmission through certification by invite send to call controller 502.This be first time certification and it for the Authentication Client on server 204.When the sending out notice comprising HS1 reaches callee's client, this is set up certification among clients direct（P2P）The first step of connection and this be second certification occur where.First stage is centralized certification, and forms control, and second stage is P2P certifications.

In a further embodiment, alternatively or additionally, discussed notice feature is invited to can be used to other communication events be notified to the user of destination's terminal, these events such as IM chat messages, voice mail or file are transmitted above for calling, sender（The user of origination terminal 102a, similar to caller above）Attempt sends these events to expected receiver（The user of destination's terminal 102b, similar to callee above）.If receiver receives, then their client 402b can or be obtained from server（Such as part of element 204）Etc. it is to be communicated, or directly obtain it from terminal 102a of sender.

It is intended that, above embodiment is been described by only by example.

For example, although the above is been described by above for the mixed P 2 P system for performing voip call, presently disclosed technology goes for other kinds of packet-based communication system.Therefore, in alternative embodiments, after notification, one of session establishment, some or all other stages（For example can be used to be called）Alternatively can carry out via one or more network centralised elements of such as one or more servers of one or more providers or operator etc.With regard to which use some P2P technologies embodiment it should also be noted that in the broadest sense, term P2P is not necessarily limited to go centralization to arrange completely.In such as some embodiments, only medium（I.e. calling or other sessions content）Needs are directly transmitted between peers, every other call signaling（Including address search and certification）Occur via central member.

Additionally, in the case of hereinbefore describing any network element in terms of server, it is intended that, this is not limited to be contained in same enclosure or positioned at the individual server unit or server of same place.According to embodiments of the invention, any logical network element realized by any one in one or more units may serve to realize communication provider function.Additionally, although the above is been described by terms of Internet traffic, each different embodiment can be used for being provided by other packet-based communication networks and notify and/or notify communication by other packet-based communication networks.

Given this disclosure, other modifications can be more clearly understood from for those skilled in the art.
