Providing following description is in order to make those of ordinary skills can realize and use the present invention.The description of concrete equipment, technology and application is just provided as example.Those of ordinary skills will be easy to the clear various modifications of seeing example described herein, and the General Principle of definition here can be applied to other examples and application, and not break away from the spirit and scope of the present invention.Therefore, the present invention is not intended to be limited to the example of describing and illustrating here, but should meet the scope consistent with claim.
Fig. 1 illustrates the example system and the environment that can use aspects more described herein.Say roughly, illustrate a plurality of first clients 110 via the first instant message converyer (" the IM ") service provider 100 of for example first service provider's agreement login and the 2nd IM service provider 102 who has a plurality of second clients 112 to login via for example second service provider's agreement.The first and second IM service providers 100,102 communicate, so that first client 110 can send and receive instant message with second client 112.In one example, communication is directly carried out between first and second networks 100,102, for example carries out (rather than first client 110 is directly communicated by letter with second network 102 or second client 112 is directly communicated by letter with first network 100) between the respective server of each network or other networking components.This system can allow the interoperability between the different IM providers.
In one example, the first and second IM service providers 100,102 can be at least in part communicate via dialogue-based initiation protocol (" SIP ") with at the agreement of the Session initiation Protocol (" SIMPLE ") of instant message transmission and existence support expansion.The SIP/SIMPLE illustration be used between the first and second IM service providers at the intercommunication of IM and existence function and a kind of agreement of interoperability.In addition, SIP/SIMPLE can be at voice, video or the like back-level server to the server interoperability.
In one example, the specific SIP/SIMPLE that is used for server-to-server interoperability purpose comprises SIP RFC 3261, SIP RFC 3265 and/or PIDF RFC 3863.In addition, the communication between the network can be filtered with required level of security and IP and be carried out server to server communication by TCP.
It will be recognized by those of ordinary skills, various other communication protocols (no matter being that open or proprietary) all are possible and have been susceptible to, use separately or are used in combination with other communication system/methods no matter be.For example, depend on specific I M service provider and required function, can carry out various modifications the SIP/SIMPLE agreement.For example, can revise any known agreement such as SIP/SIMPLE, be used in the given network with more effectively (for example with regard to transmission speed, process, cost etc.).In addition, realize or help communication between the different IM providers and/or other suitable communication protocols such as XMPP of interoperability can be used alone or be used in combination with the SIP/SIMPLE agreement.
Client can communicate via wireless network via computer equipment, and this wireless network for example is a radio network gateway, for example honeycomb, satellite or other wireless networks.In addition, computer equipment can be via the row communication that is combined into of the non-wireless network such as cable or fiber optic network or wireless and non-wireless system.Computer equipment can comprise suitable hardware and software, for example is connected to the processor of input equipment, network interface, memory and display such as keyboard.Memory can comprise and can operate to carry out some the logic OR software in the function described herein with equipment.Equipment can be operated and comprise suitable interface to be used for messaging facilities, for example email INBOX, instant message transmission (IM), short message passing service (SMS), Multimedia Message passing service (MMS) or the like.
Mail account or Hotmail
The web email environment of account and so on.
Network 100,102 can be communicated by letter with Database Systems with one or more servers or be comprised one or more servers and Database Systems, and these one or more servers or Database Systems are communicated by letter each other, and can with a plurality of users' devices communicating.Exemplary server system can comprise various routers, database, gateway and server, for example edge or acting server, gateway server, Mobile Server, e-mail server, web server, speech message delivery server or the like.In addition, network 20 can comprise wireless network and one or more Local Area Network and/or wide area network (WAN), for example internet of realizing the communication between various users, equipment, server, agency, module, client, processor or the like.
In an exemplary operation, the user utilizes effective I D and password to login elementary network via client 110.After the user successfully logins in the elementary network 100, the reservation that client 110 and/or elementary network 110 send the existence/state that is in the good friend on the secondary network 102, and the notice of the existence/state on the elementary network of the observer on the secondary network 102 (for example client 112 that is associated with client 110) transmission indication.If the user publishes elementary network, then suitable reservation/notification message is sent to the good friend on the secondary network.
The user also can stop/ignore the contact person from secondary network; Be used to add this new contact person from the ID of new contact person on secondary network of secondary network; Deletion is from the contact person of secondary network; And the contact person from secondary network is carried out rename.
Fig. 2 illustrates the overview of the exemplary IM service provider network that can use aspects more described herein.Not all assembly all is essential, can make variation on the layout of assembly and type under the situation of the spirit and scope that do not break away from each invention.
In one example, comprise edge proxies 212 corresponding to the elementary of an IM service provider or first network 200.Edge proxies 212 can at an IM service provider and comprise one or more outsides of one or more IM service providers or field network (for example field network 202) between SIP/SIMPLE or other communication protocol used dispose.Particularly, edge proxies 212 is provided to the connection processing and the route of external network.Edge proxies 212 assemblies are optionally, and in other examples gateway 214 can directly communicate by letter the edge proxies or the network service of another network (for example direct and) with another server or networking component.But, realize that general edge proxies 212 but makes easier and a plurality of external networks form an alliance.Comprising of edge proxies 212 also helps to make the alliance's route and the connection processing centralization of going to one or more external networks.
In this example, gateway 214 is the last SIP nodes that enter first network, and as the client of acting on behalf of first network to the SIP end points of external network.Therefore, gateway 214 comprises and can operate the logic that SIP/SIMPLE communication/incident or the like is changed into the local or elementary protocol communication within the rear end of network 200.For example, gateway 214 helps to convert the SIP flow at specific elementary network/IM service provider local or elementary agreement, and vice versa.In general, the scalability limitations of gateway 214 (assembly that perhaps is equal to) depends on the performance (with reference to figure 3 more detailed descriptions) of sip stack implementation.In addition, depend on particular network and/or assembly, can carry out various optimizations to realize batch reservation and notice, to improve scalability at the SIP layer.In one example, gateway 214 is SIP gateways, and wherein sip stack is optimized to handle batch reservation and notice.
Gateway 216 comprises gateway event server (ES), and processing is communicated by letter with various back-end servers, described various back-end server for example is the local elementary webserver, as reverse good friend (reverse buddy) event server 218, event server 220 and Connection Service device 222.Gateway 216 also can be operated derives the general reservation and the dialog model that can be used in combination with the exterior I M/ existence agreement of any kind.In one example, gateway 216 still is stateless and highly scalable.
The transition condition of session manager 242 general storage dialogues.In one example, session manager 242 uses scalable distributed caching mechanism in memory stores, but other implementations also are possible.
Can comprise extra support from various other servers on the first network rear end.For example, rbum/rbes 218 can operate and oppositely store and retrieving outside id in the buddy list.Event server (ES) 220 can be determined external domain, so that message can suitably be forwarded to gateway 216, thereby and is forwarded to SIP gateway 214 (and finally be forwarded to suitable external network and external user).
Fig. 3 illustrates the block diagram of the assembly of exemplary gateway 300; For example comprise SIP/SIMPLE gateway (SIP gateway 214 for example shown in Figure 2).The SIP/SIMPLE gateway comprises " connection manager ", this connection manager can operate handle and the either side of network on the network I/O (for example between external network and the elementary network/rear end) of other assembly/servers.It also can be operated being used for optional Transport Layer Security (for example encrypt, authorize or the like), and extracts the transport layer details from other assemblies.The level of trust that depends on mutual with it assembly, security mechanism can be filled into mutual Transport Layer Security (MTLS) from simple IP to be changed.In one example, can realize very effective I/O in the network service some or all based on asynchronous queue (kqueue).In addition, the size of connection pool and behavior can be controlled via configuration parameter.
In one example, gateway comprises sip stack 300, and this sip stack 300 can comprise open-source sip stack, commercial sip stack or proprietary sip stack.In addition, SIP level of abstraction 320 can be operated the remainder that gateway is realized and not know the sip stack 310 that just is being used.It is this abstract that general API and object set can provide.As a result, this design is a significant benefit to and adopts diverse or amended SIP implementation (if necessary).
Also comprised SIP end points existence dialog manager 330 in this example.For example, for hope and the elementary networking client that the outside/correspondent's end (for example MSN client) is communicated by letter, this building component logic SIP tip node (end points).Tip node is created when the network either side is interested as required.Each SIP SUBSCRIBE and the INVITE dialogue that appends in these tip nodes followed the tracks of and managed by dialog manager.Following SIP function can be handled by the elementary networking client of SIP end points existence dialog manager 330 representatives:
Represent elementary networking client transmission/reception SUBSCRIBE.
Represent that elementary networking client is followed the tracks of, management SUBSCRIBE dialogue (import into and spread out of).
Represent elementary networking client transmission/treatment S UBSCRIBE to refresh.
Represent elementary networking client transmission/reception NOTIFY.
Resolve and arrangement PDIF existence information (PDIF: the existence information data format).
Convert elementary networking client existence warning to the PDIF form.
Represent elementary networking client transmission/reception INVITE.
Represent elementary networking client tracking, managing I NVITE dialogue.
Represent elementary networking client transmission/reception IM.
Represent elementary networking client transmission/reception to key in notice.
Represent elementary networking client transmission/reception UNSUBSCRIBE.
SIP end points existence dialog manager 330 assemblies also can be safeguarded state information and the look-up table of himself, to help that various SIP dialog are mapped to its corresponding elementary network client end contact.In addition, this assembly can be operated and be a plurality of point (MPOP) or a plurality of tip nodes of existing of same elementary network client maintenance.
Owing to generally have more than a gateway machine in operation (for example on elementary network), and given tip node only has its associated state in a gateway machine, therefore session manager (for example referring to Fig. 4) can also help to route messages to suitable gateway machine in network, and vice versa.Suitable logic can guarantee that message is processed in the suitable context of dialogue, and can not endanger the scalability of system.
In addition, in this example, gateway comprises the local bridge 340 of SIP-.The local bridge 340 of SIP-generally operate with message from the SIP format conversion to local back end format, vice versa, for example is transformed into the network local form, vice versa.Elementary network for example can comprise use relatively fast, the server of the status storage concentrated, this makes each machine stateless.This architecture has generally realized the seamless cluster/load balance between the gateway and the elementary webserver.The local bridge 340 of SIP-utilizes local elementary procotol and this elementary network server cluster dialogue.It also receive and handle from each elementary networking client, be the message of target with outside networking client.
Fig. 4-21 illustrates various example communication and the incident flow process between the assembly with one or more external networks/first network rear end that instant message passing service provider communicates by letter.
Fig. 4 illustrates the overall architecture that comprises with the preliminary service provider network rear end of the gateway of external network communication.In this example, edge proxies (EP) 412 be provided for go to and from the access control of external network, set and route, and connect and converge and go to and from the SIP/SIMPLE forwards of external network.In general, edge proxies 412 can operate and be configured to and one or more field communications.In addition, SIP gateway (SGW) 414 is operated to act on behalf of elementary networking client as the SIP end points to external network, and elementary network instant message transmission request is mapped in the SIP/SIMPLE message, and vice versa.In one example, SGW 414 depends on sip stack (for example open-source sip stack, commercial sip stack or proprietary sip stack), and state is arranged.Gateway ES (GWES) 416 operates with gateway requests between processing domain (mainly being IM and existence); Bridge joint SIP gateway 414 and one or more elementary network back-end server; GWES416 is that state arranged and highly scalable in one example.
This architecture also is included as the session manager (SM) 442 of the back-end server storage SIP dialog routing iinformation of elementary network.For example, each record as keyword, and comprises the SGW keyword that points to the specific SGW server 414 of preserving corresponding SIP dialog with elementary networking client id, gateway id and dialogue types (IM, existence etc.).The session manager server is in the memory buffer management system, and this system supports data partition and equity to duplicate.
The lasting information (for example buddy list or other information) of gateway DB (GWDB) 440 storage external users.In one example, the MySQL server is used as lasting storage device.In one example, GWDB 440 is configured to support data partition and equity to duplicate, but lacks shmproxy, for example connects aggregate capabilities.
Fig. 4 illustrates a kind of implementation that is used for the example architecture of external network communication; But various other architectures also are possible.For example, various assemblies can be deleted, and/or their function can be combined with other assemblies.For example, single gateway equipment can comprise the logic of the function that is used to carry out GWES 416 and SGW 414.In addition, in some instances, edge proxies 412 can be removed, and perhaps its function is carried out by another machine.
Continuation is with reference to figure 4, and Fig. 5 illustrates the user and signs in to situation in the elementary network.When the user in 1.1 whens login, event server (ES) 420 (referring to Fig. 4) is carried out following operation: for each good friend, ES 420 his/her territory of identification and before login, in the data 1.3 this information is sent to client.In addition, after login 1.3, notice is sent to external user/observer, for example oppositely the good friend (for example from ES server 420 to GWES 416 to SGW 414 again to external network; 2.1-2.2).In one example, ES 420 is notified to RBES (it can be included in the ES400) with user login, and RBES utilizes the external user/observer on the reverse buddy list of domain information identify customer end, and RBES sends notice to GWES 416.GWES 416 searches the SGW keyword from SM 442, correspondingly the external observer is classified, and sends notice to SGW 414.SGW 414 searches the dialogue at the external observer in memory buffer, send SIP NOTIFY request via dialogue to external network then.If SGW 414 can't find the dialogue at the external observer, then it should be beamed back to GWES 416 and remove reservation request to stop following notice.
In addition, client subscribe outside good friend existence information (for example from ES 420 to GWES416 to SGW 414 again to external network; 3.1-3.5).In one example, ES 420 utilizes union domain information to discern outside good friend on the user's of preliminary service provider the buddy list, and sends reservation requests to GWES 416.GWES 416 sends reservation request to SGW 414, and for each outside good friend, SGW 414 checks whether there has been dialogue for this reservation.If then it sends request to refresh reservation to external network; Otherwise it creates new dialogue for the external network good friend, and sends SIP SUBSCRIBE request to external network.When SGW 414 obtains from the ok of external network or error responses, the dialogue that its upgrades or deletion is buffered accordingly, then with response pass to GWES 416.If response is " ok ", then GWES 416 is saved in SM 442 with the SGW keyword.If subscribe owing to the mistake of forbidding is rejected, mean that then external user is no longer valid.GWES 416 can remove external user from UDB 422 and GWDB 440, and can send notice to elementary networking client.
In one example, the outside good friend who subscribes at success can send initial existence notice, and should initial existence notice can comprise and can be notified by the off-line that client filters out (for example from the external network to SGW 414 to GWES 416 again to elementary networking client; 4.1-4.3).For example, external network sends notice to SGW 414.If do not find corresponding dialogue, then SGW 414 abandons this notice; Otherwise it is delivered to GWES 416 with notice.GWES 416 converts notice to elementary/native format or agreement, and GWES 416 obtains to arrive elementary networking client from the target link information of UM 420 and with delivery of notifications.
Fig. 6 illustrates the exemplary login process of external user.In this example, when external user was logined, notice was sent to elementary network observer and (for example is routed to SGW 414 from external network, arrives GWES 416 again, arrive elementary networking client again; 1.1-1.3).Particularly, external network sends notification line at each elementary network observer to SGW 414.SGW 414 searches the respective dialog at elementary network observer, and if do not find dialogue, then SGW 414 will send error responses to external network, and this notice will not sent.If found dialogue, then SGW 414 is forwarded to GWES 416 with notice, and 416 pairs of notices of GWES are filtered, transformed, and it is delivered to elementary network observer.
External user can be subscribed subsequently with the existence state of observing elementary networking client good friend and (for example flow to SGW 414 again to GWES 416 from external network; 2.1-2.5).Particularly, external network sends the reservation request at each elementary network good friend.SGW 414 subscribes for this and creates dialogue, and reservation request is sent to GWES 416.Whether externally GWES 416 searches GWDB 440 to check elementary networking client on user's the buddy list, and if not, then it is interpreted as adding good friend (Add Buddy) request with this request.If elementary networking client is on buddy list but still issued for approval, then GWES 416 sends the ok response of following the off-line notice to SGW 414.If elementary networking client is an active buddies, then GWES 416 sends request to RBES 418, external user is added to the reverse buddy list of elementary networking client, retrieve the initial existence state of elementary networking client then from UM420, transform this state if necessary, and send it to SGW 414.If SGW 414 obtains the ok response from GWES 416, then its upgrades the dialogue in buffer memory, and will respond and initially the existence state notifying be delivered to external network.If the error responses that SGW 414 obtains from GWES 416, then its deletes the dialogue in buffer memory, and error responses is sent to external network.
In some instances, for some network rear ends, if external user is logined from a plurality of positions, then the user will send a plurality of reservations to elementary network.In this case, can to create in its memory buffer and preserve with external user id be a plurality of dialogues of keyword to SGW 414.If elementary afterwards networking client good friend sends the existence notice to external user, then this notice will be delivered to and utilize corresponding each external position of a plurality of dialogues that SGW 414 preserves.
Fig. 7 and 8 illustrates the process of publishing of naive user and external user respectively.If elementary networking client is published, then off-line notice be sent to the external observer (for example from ES 418/RBES to GWES 416 to SGW 414 again to external network; 1.1-1.3).In addition, carry out releasing booking process at outside good friend's existence (for example from ES 418 to GWES 416; 2.1-2.2).For example, GWES 416 searches the SGW keyword from SM 442, and request is delivered to corresponding SGW 414.It removes the SGW route record subsequently from SM 442.SGW sends to external network and removes reservation request, and deletes the respective dialog in its memory buffer.
If external user is published, then off-line notice be sent to elementary networking client observer (for example from the external network to SGW 414 to GWES 416 again to elementary networking client; 1.1-1.3).In addition, carry out elementary networking client good friend existence the releasing booking process (for example from the external network to SGW 414 to GWES 416 again to RBES 418; 2.1-2.2).SGW 414 deletes respective dialog and sends the releasing reservation requests to GWES 416.GWES 416 removes SGW 414 routes from SM 442, and removes external user from observer's tabulation (being reverse buddy list) of elementary networking client good friend.
Fig. 9 and 10 illustrates respectively and changes the process that its existence state is associated with elementary networking client and external user.In one example, elementary networking client changes its existence, and it sends the existence notice.RBES 418 utilizes which reverse good friend of union domain information Recognition from external network, and sends notice to GWES 416.The existence notice changes the external network that is sent to the external observer subsequently.In one example, GWES 416 filters or is converted into suitable external status with elementary network client state.GWES 416 searches the SGW keyword from SM 442, and sends notice to SGW 414.For each existing dialogue, SGW 414 sends to external network with notice; If do not find dialogue, then SGW 414 should beam back to GWES 416 and remove reservation request to stop following notice.In one example, if do not match between elementary network client state and the external status, then notify by GWES 416 and filter out (abandoning).
If external user changes the existence state, 414 of SGW find out corresponding dialogue (and if do not find dialogue then can send error responses to external network).SGW 414 is delivered to GWES 416 with notice, and GWES 416 changes into the existence notice matching status of elementary networking client.If desired, elementary network can utilize customized messages that non-matching status is changed into local state.GWES 416 obtains the target link information from UM 420, and with delivery of notifications to suitable elementary networking client.
Figure 11 and 12 illustrates the example process that user's termination is subscribed from the user's of different providers existence.For example, in Figure 11, elementary network client terminate is subscribed from the existence of external user, and this may be useful for junk information control or the like.Client is handled by GWES 416 request that stops, and GWES 416 requests stop the reservation of external user.GWES 416 is from the buddy list of GWDB 440 acquisition external users, and GWES 416 removes external user to the reverse buddy list of RBES transmission request with elementary networking client good friend from each.
The request of stopping is sent to external user (for example from GWES 416 to SGW 414 again to external network) subsequently.In one example, GWES 416 searches the SGW keyword from SM 442, and sends the request of termination to SGW 414.GWES 416 removes the SGW route record from SM 442, and the dialogue in SGW 414 its memory buffer of removing, and sends the request of termination to external network.External network sends the off-line notice to external user, and external network suitably upgrades its reservation file.GWES 416 is recorded in it with this request and stops in the daily record.
In addition, as shown in figure 12, external network can stop subscribing from local user's existence.In one example, SGW 414 receives the request of elementary networking client to the reservation of the existence of external user that stop.The dialogue that SGW 414 removes in its memory buffer, and to GWES 416 transmission termination requests.GWES 416 removes route record from SM 442, and GWES 416 sends the off-line notice to elementary networking client.If at elementary networking client external user has been off-line, whether then elementary this notice of networking client decidable should be filtered.
Figure 13 and 14 illustrates the example process that the local user adds outside good friend.In first example Figure 13, elementary network client-requested is added to good friend (for example adding its buddy list etc. to) with external user.From external network, initial off-line notice 2.1-2.3 (affirmation of the reservation that is triggered as the interpolation good friend request to client) is notification line 3.1-3.3 (this process supposition external user has been ratified the interpolation good friend request of elementary networking client) afterwards.
Particularly, when external user was added in elementary networking client request, ES 418 added external user the buddy list of the elementary networking client among UDB and the UM 420 to, then request is delivered to GWES 416, because new good friend is an external user.GWES 416 is delivered to SGW 414 with this information subsequently, and is delivered to external network, to subscribe the existence (asking external user to be added under good friend's the situation at elementary networking client) of external user.If SGW 414 obtains the ok response from external network, then SGW 414 is kept at dialogue in the memory buffer, and with response pass to GWES 416.GWES 416 adds route record to SM 442, and sends the ok response to elementary networking client.If SGW 414 obtains the invalid error responses of the outside id of indication from external network, then SGW 414 deletions are talked with accordingly and are sent error responses to GWES 416.Remove external user in the buddy list of the elementary networking client of GWES 416 from UDB and UM 420, and send error responses to elementary networking client.
From external network, off-line notice is initial to be sent out (for example from SGW 414 to GWES 416 again to elementary networking client, notice external user off-line) as the affirmation to the reservation request that sent.Whether elementary networking client decidable abandons initial off-line notice.At last, from external network, show that the online notification line of user (the supposition external user has been ratified interpolation good friend request) is sent out.
In one example, after the ok response to reservation request that obtains from external network, external user is added to the buddy list of elementary networking client immediately.On the customized configuration of this example, do not have state co-pending, when do not accept/refuse to add request because do not need to detect external user.
Figure 14 illustrates the example that the external user refusal adds.This process/incident flow process and Figure 13's is similar, has just lacked last a series of incident 3.1-3.3 (for example lacked external user and accepted interpolation).
Figure 15 and 16 illustrates the example process that is used for elementary networking client is added to the good friend of external user.In general, the external user request is added to the good friend with elementary networking client, and request is added in the approval of elementary networking client.
More specifically, external user asks elementary networking client is added to good friend (1.1) by the existence of subscribing elementary networking client.SGW 414 sends reservation requests to GWES 416, and GWES 416 searches GWDB 440 and detects this request and hinting the interpolation good friend, because elementary networking client is not externally on user's the buddy list.Whether GWES 416 searches UDB 420 effective to check elementary networking client id.If not, then send error responses to external network via SGW 414.If elementary network id is effective, then GWES 416 sends the ok response to SGW 414.SGW 414 creates dialogue and the ok response pass is arrived external network in buffer memory.In one example, external user is apprised of elementary network client off-line (for example from GWES 416 to SGW 414 again to external network).GWES 416 adds route record in SM 442, and GWES 416 adds elementary networking client to state co-pending the buddy list of the external user among the GWDB 440.(for example arrive elementary networking client again) from elementary network client-requested approval at last via GWES 416 to UM 420.
If request is added in elementary networking client approval, then ES 418 ratifies a motion to GWES 416 transmission interpolation good friends.GWES 416 changes over activity with the state of elementary networking client good friend among the GWDB 440 from co-pending.GWES 416 sends update request to RBES 418, external user is added to the reverse buddy list of elementary networking client.The presence that GWES 416 obtains from the elementary networking client of UM 420, and convert it into external status.The online existence notice of elementary networking client is sent to external user (for example arriving external network and user again via GWES 416 to SGW 414).
In GWDB 440, each good friend record comprises a state (for example movable, co-pending, be rejected) and a timestamp.This state can be used for various purposes, and for example good friend's flow process is added in management, and this timestamp can be used for protecting elementary networking client to exempt from harm from the too much SUBSCRIBE of external network, and can be used for refuse collection.
Figure 15 illustrates the example that elementary networking client refusal adds request.This process/incident flow process and Figure 14's is similar, has only lacked last a series of incident 2.2-2.4.In addition, incident 2.1 is to make the state of elementary networking client into " being rejected " from " co-pending " on the buddy list of the external user in GWDB 440.In some instances, external network can not given external user with the refusal event notice, but a reservation request is just arranged when each external user is logined again, and elementary network can be preserved and be rejected the state that is rejected that request is associated.Good friend's record with the state of being rejected can be used as refuse collection after the regular hour section.
Figure 17 and 18 illustrates the example process that is used for from the deletion good friend of external web services provider.In Figure 17, elementary networking client is deleted outside good friend.In this example, GWES 416 checking external users are good friends of elementary networking client, and remove external user in the buddy list of GWES 416 elementary networking client from UDB and UM420.Elementary networking client is apprised of subsequently to deleted request responding (for example from GWES 416 to CS 420 again to elementary networking client, such as the response of ok, mistake or the like).In addition, GWES 416 and SGW 414 (thereby with external network) communicate by letter, to remove the reservation of the existence of external user and to remove dialogue and route record.
In Figure 18, show the cater one's wishes situation of the elementary networking client of deletion in the friend tabulation of external user.In this example, external user is removed the reservation to the existence of elementary networking client.SGW 414 removes dialogue, and SGW 414 sends the releasing reservation request to GWES 416.GWES 416 removes the route of past SGW 414 from SM 442.In addition, GWES 416 removes external user from the reverse buddy list of elementary networking client.
Figure 19 illustrates the example process of beginning IM session between elementary networking client and external user.In this example, elementary networking client utilizes elementary networking client to initiate the IM session, with the IM session (for example request from elementary networking client from ES 418 be transferred to GWES 416) of request beginning with external user.The new session of GWES 416 checkings.In one example, whether the elementary networking client of systems inspection does not support the session based on IM, if then return error is sent to client, otherwise just sends beginning IM conversation request to SGW 414.If IM session dialogue exists, then return ok to GWES 416; Otherwise send the SIPINVITE request to external network.
The response that SGW 414 obtains from external network, if response is ok, then the session dialogue is stored in the buffer memory, otherwise talks with deleted.SGW 414 also sends response to GWES 416.The response that GWES 416 obtains from SGW 414; If response is ok, then SGW 414 route records is kept among the SM, and response pass is arrived elementary networking client.At this moment, elementary networking client can send IM communication.
Do not support to bring in the example of initiating the IM session based on the client of the session of IM in elementary networking client utilization, process is as follows.Elementary networking client sends an IM to ES 418.ES 418 identification recipients are external user (utilizing union domain information etc.), and request is forwarded to GWES416.GWES 416 searches SM 442, and determines still not have the IM session for sender and recipient, so it sets about carrying out new session checking (for example being to check YPCminor in the case).If authentication failed, then mistake is sent to elementary networking client, otherwise an IM is sent to SGW 414.SGW 414 searches buffer memory, and finds still not exist session, and IM is carried out buffer memory and sends SIP INVITE request to external user.The response that SGW 414 obtains from external user; If session is accepted, then SGW 414 upgrades the dialogue in the buffer memorys and IM is gone out the outside, and if session is rejected, the initial dialog in the SGW 414 deletion buffer memorys and abandon the IM that is buffered then, and send response to GWES 416.If session is accepted, then GWES 416 obtains the response from SGW 414, and SGW 414 is kept at route among the SM442.
Figure 19 also shows the example of the IM session of external user initiation and elementary networking client.External network sends SIP INVITE to SGW 414.If had IM dialogue (for example a plurality of external network clients are moved) for sender and recipient, then SGW 414 sends SIP BYE to finish previous session to external user, then the new session dialogue is saved in buffer memory.SGW414 sends beginning IM request to GWES 416, and GWES 416 checking new sessions.For example, GWES 416 checks whether elementary networking client id is effective, checks the YPC restriction, and checks the tabulation of ignoring of elementary networking client (recipient) whether.If checking ok, then GWES is kept at the SGW keyword among the SM, and returns ok to SGW 414; Otherwise it sends mistake to SGW414.The response that SGW 414 checks from GWES 416, and correspondingly upgrade or the deletion initial dialog.SGW 414 sends ok or error responses to external network subsequently.
Figure 20 illustrates the exemplary event flow process of the key entry notice that is used between elementary networking client and the external user.After the IM session was established, IM and key entry notice request can be exchanged.For the request from elementary network to external network, GWES 416 searches the SGW keyword from SM, then request is sent to corresponding SGW 414 servers, and SGW 414 servers are forwarded to external network with it subsequently.For the request from external network to elementary network, SGW 414 searches corresponding dialogue in buffer memory; If do not find dialogue, then request is dropped; Otherwise request will be sent to GWES416, and GWES 416 is delivered to it suitable elementary networking client subsequently.
Figure 21 illustrates the incident flow process that is used to finish the IM session between elementary network and the external user.If elementary network client terminate IM session, the request that then stops is transmitted to GWES 416 to finish the IM session by ES 418.GWES 416 searches the SGW keyword from SM 442, sends request to SGW 414, and from SM 442 deletion SGW route records.Dialogue in the SGW 414 deletion buffer memorys, and send SIP BYE with end session to external user.
If external user finishes the IM session, then external user sends SIP BYE to SGW 414.Dialogue in the SGW 414 deletion buffer memorys also sends to GWES 416 and to finish the IM conversation request.SGW route record among the GWES 416 deletion SM.In addition, GWES 416 can send to elementary networking client and finish the IM conversation request.
