The present invention goes for supporting Any user terminal, server, the assembly of correspondence and/or the combination in any of any communication system or different communication systems of conversation-based group communication.Communication system can be a fixed communications, perhaps wireless communication system, or use the two communication system of fixed network and wireless network.The standard fast development of employed agreement, communication system and server, especially true in radio communication.This development may need the extra change to execution mode.Therefore, all terms and expression should broadly be explained, and it is intended to illustrate and unrestricted execution mode.
Hereinafter, to adopt the chat (as the example of group communication) of use instant message and (also be based on being used for signaling and session foundation, the instrument that makes up the multimedia framework is provided) SIP (Session initiation Protocol) and the framework (as the example that can use system architecture of the present invention to it) that is used for the MSRP (message session trunk protocol) of group communication the present invention is described, yet, the invention is not restricted to this group communication and this framework.SIP and MSRP are defined by the Internet engineering duty group (IETF).SIP is used to create, revise and application layer control (signaling) agreement of termination and one or more participants' session.MSRP be used for as one to one or one-to-many communication after session is set up, between 2 o'clock, carry the application layer protocol of a series of instant messages.In other words, SIP and MSRP and non-perpendicular being integrated in the communication system.Ietf specification and internet draft can find at http://www.ietf.org.
The general framework of the communication system that conversation-based group communication is provided has been shown among Fig. 1.Fig. 1 is the system framework of simplifying, and it only shows some elements and functional entity, and it is logical block all, and its realization can be with shown different.Connection shown in Fig. 1 is that logic connects; Actual physical connects can be different.What easily see to those skilled in the art is that this system also comprises other functions and structure.Should be appreciated that, be used for group communication or irrelevant in the employed function of group communication, structure, element and agreement and actual invention.Therefore, need not it to be gone through at this.
Communication system 100 among Fig. 1 comprises user terminal 300,300 ', 300 "; each user terminal can be connected to the server 200,200 ', 200 of its oneself Virtual network operator via carrier network ", each Virtual network operator preferably includes Access Network and core net, and may be connected to other carrier networks via the route network (not shown in Figure 1) such as the Internet.
User terminal 300,300 ', 300 " be one group of such device or equipment; and it carries out related with subscription user terminal and user thereof; perhaps be arranged to user terminal and user thereof and subscription are carried out related, and allows user and communication system to carry out alternately.User terminal is to user's presentation information, and the permission user's input information.In other words, user terminal can be can from network receiving information and/or to network emission information, can be wirelessly or via fixedly connected and be connected to any terminal of network.The example of user terminal comprises personal computer, game console, laptop computer (notebook), personal digital assistant, travelling carriage (mobile phone) and telephone.
Server 200,200 ', 200 " can provide server, the chat room server of the access of chat room server or serve as this two servers.It is carrier network that can be by the user, the server that uses the subscription of operator to visit that server to the access of chat room server is provided.Chat room server provides chat room services for one or more sessions, such as other participants to the chatroom send instant message, safeguard with chat in each participant the SIP signaling relation, be responsible for guaranteeing that each participant receives the medium that constitute chat and realizes that chat is tactful.For example, the server C 200 ' of the C of operator is used for user terminal 300,300 ', 300 " chat room server, and the subscription of using the C of operator provides access to chat room services to user terminal 300 '.Chat room server also contains the server and/or the Control Server of center, master control session here.Provide server can be called as the participation server to the access of chatroom.
Provide to the access of chatroom and/or as the server 200,200 ', 200 of chat room server " according to being used for providing group communication service.Server can also comprise a plurality of application except that chat or session, and it should be used for providing group communication service to the subscriber according to one, although Another Application can be used for another chat of same subscriber or be used for another subscriber's same chat but.Provide the application of group communication service can provide any application of conversation-based group communication.Based on SIP and provide the application example of instant message transrecieving service to comprise to group at least: PoC (push-to-talk over cellular, by the open mobile alliance OMA definition), perhaps IETF SIMPLE (also is, the SIP that is used for instant message transrecieving and on-site support expansion by ietf definition), perhaps OMA instant message transrecieving service (also promptly, by the OMA definition, based on the instant message transrecieving enabler of SIP/SIMPLE agreement).The OMA standard can find at http://www.openmobilealliance.org.Making the time of the present invention, the private message in the OMA instant message transrecieving service support group communication, but PoC and IETF SIMPLE do not support.Thus, server 200,200 ', 200 " for example can be the PoC server, perhaps OMA instant message transrecieving server, perhaps IETF SIMPLE instant message transrecieving server.
Should be appreciated that the chatroom in the server can provide the access to chat room services to the different operators (more accurately, to the user who uses its subscription) of arbitrary number.In other words, carrier network and server 200,200 ', 200 " represent one or more corresponding carrier networks and intermediate server at this.It is also understood that the access to different chatrooms can be provided by the different chat servers of different operators.
Fig. 2 provides the block diagram of the device of one or more servers of group communication service or server component (for example, module) according to embodiment of the present invention, expression.Although device is depicted as an entity, different modules and memory can be realized in one or more physical entities or logic entity.Device 200 is arranged to: detect the private message in the group communication message; Use checks about the ability information of next node whether this next node supports the private message in the group communication, and described ability information receives when inviting the participant for example to add group communication; And determine how to handle private message according to check result.For this purpose, this device comprises: data storage device 20 is used for preferably session and specifically and at least temporarily stores ability information about next node; Receiver unit 21 is used to receive different inputs, information and message; Conversation information maintenance unit 22 is used to pay close attention to the ability information of storage about next node; Detecting unit 23 is used to detect the private message in the group communication; Privacy supplier unit 24 is used to use ability information to check whether next node supports the private message in the group communication, and is used to use check result how to decide processing messages, and is used for determining processing messages according to this; And transmitting element 25, being used to send different output, information and message, this transmitting element responds privacy supplier unit 24 at least.
User terminal can also comprise corresponding construction or the configuration of carrying out corresponding function when being used for sending private message in group communication.
The device of the function of the related device that realization is described by execution mode (for example, server or corresponding server component, user terminal and/or other corresponding apparatus or device) not only comprise prior-art devices, but also comprise: be used for checking in response to the private message that sends at group communication whether next node supports the device of the private message in the group communication; Be used for deciding device how to handle private message according to check result; And the device that is used for determining to handle private message according to this.More accurately, it comprises the device of the function that is used to realize the related device described by execution mode, and it can comprise the self-contained unit that is used for each standalone feature, and perhaps device can be arranged to and carry out two or greater functionality.This device comprises the processor and the memory that can use in execution mode.For example, detecting unit 23 or privacy supplier unit 24 or its combination can be to be configured to by the algorithm operating of Operation Processor execution or software application or the module or the unit of program.All modifications that the function of realization execution mode is required and configuration can be used as routine and carry out, and these routines can be implemented as software routines, application circuit (ASIC) and/or programmable circuit newly-increased or that upgrade.Software routines (being also referred to as program product) comprises applet (applet) and grand, and it can be stored in the readable data storage medium of any device, and it comprises the program command that is used to carry out particular task.Software routines can download in the device.Device such as server or corresponding server component or module or user terminal can be configured to computer or microprocessor, such as the monolithic computer element, it comprises at least: be used to be provided for the memory of the storage area of algorithm operating, and the Operation Processor that is used for the execution algorithm operation.The example of Operation Processor comprises CPU.Memory can be the removable memory that removably is connected to device.
Device in the message delivery chain of group communication service is provided (also promptly, node) can be arranged to the realization embodiments of the present invention, no matter and whether whether this device provides the access of chatroom or its be chat room server or user terminal.Preferably, the device in the delivery chain is arranged to realizes identical execution mode, but this is also nonessential.Device in the delivery chain can be arranged to realizes different execution modes, and/or the one or more devices in the delivery chain can be not to be arranged to the device of realizing embodiment of the present invention.Also may have only chat room server node to be arranged to the realization embodiments of the present invention.Next node in the delivery chain contains node from message to its address that transmit at this, so encompasses users terminal and server, and message is not node the delivery chain from its intermediate node that passes through.Forwarding is also contained the copy that generates origination message and is sent copy at this, and wherein copy can have different " next node address " with origination message.
Hereinafter, use message as with group communication in the mode that communicates of other participants different execution modes is shown.Yet for the purpose of clear, sending of message in detail openly has nothing to do with the present invention because send details.
Fig. 3 shows flow chart such as the different execution modes of the device of server or server component to Fig. 6.In the embodiment shown, for the purpose of clear, suppose that group communication session sets up, allow the sender to send private message in group communication, and device has the ability information about next node, this ability information special session at least therewith is correlated with.In addition, suppose group communication based on instant message, this is not to be to limit the invention to this scheme.
With reference to figure 3, in step 301, device is received in the instant message that sends in the session that forms at group communication.In response to receiving instant message, device checks whether this message is private message.For example, if message comprises one or more recipients address or sign rather than group identification or session identification, can be private message then with this message interpretation.If instant message is not a private message, then installs instant message is forwarded to next node in step 303.
If instant message is private message (step 302), then install step 304 use ability information check next node whether support consider private message in the group communication.In other words, check whether next node supports privacy.If node is supported privacy, then install instant message is forwarded to next node in step 303.
If next node is not supported privacy (step 304), then install at this instant message of step 305 refusal, and in step 306, by for example to the sender of instant message or be actually the last node that Xiang Congqi receives message and send the sender that error message comes notification message, wherein this error message preferably has explanation, for example " does not allow to send private message to the expection recipient ".
In other words, in the execution mode of Fig. 3, based on the check result of the ability information of using next node, device is by transmitting detected private message or by refusing this message and will refuse to notify the sender, thereby handles this message.
The advantage of this execution mode is, it guarantees that message is not forwarded to the server of not supporting the private message in the group communication, guarantee thus: if such server provides the chatroom, it will can not receive private message and therefore private message can not revealed to all participants.Another advantage of this execution mode is, if recipient's user terminal is first node of not supporting private message in the group communication in the delivery chain, then message can not send to this user terminal, has guaranteed that thus private message will can not be interpreted as group message.If private message is received as group message, then the recipient may not recognize the sensitiveness of this message, and may reply, and this answer will be sent to other participants of group communication equally, thereby destroys privacy.This can be avoided by this execution mode.
The execution mode of Fig. 4 uses " pressure-identification designator ", and the sender of the message comes notification receiver with it: for this message of correct understanding, it it must be understood that this designator.Gpio line that the above-mentioned example of group communication is supported and instant message transrecieving (CPIM) will require header (require header) to be defined as " pressure-identification designator ", the feature that its indication recipient it must be understood that, and the execution mode of Fig. 4 has used this to require header.Yet corresponding execution mode can utilize " pressure-identification designator " of other types to realize.
With reference to figure 4, step 401 arrives step 304 to step 404 corresponding to the step of above describing with reference to figure 3 301, no longer repeats here.
In the execution mode of Fig. 4, if next node is not supported privacy (step 404), in step 405, device checks whether message comprises as the indication of the mandatory header that requires to the support of private message in the group communication.For example, the private message that certain user's terminal can be arranged in group communication is added this header that requires, and perhaps header is by another node interpolation formerly.Indication is supported requires the header can be simply as " Require:Private (requirement: secret) ".If message does not comprise this header that requires, in step 406, device adds this header that requires to message, and will have the forwards of requirement header to next node in step 407.In other words, be provided with and require header require to support private message in the group communication with indication.
If message comprised as the requirement of mandatory to the support of private message in the group communication require header (step 405), then install in step 407 and transmit this message.
In other words, in the execution mode of Fig. 4, check result based on the ability information of using next node, device by transmit detected private message or by guarantee this message comprise as the indication of mandatory to the support of private message in the group communication require header or respective indicator, thereby handle this message.
The advantage of the execution mode of Fig. 4 is: private message only is delivered to the recipient who supports private message in the group communication, and is not delivered to the recipient who does not support private message in the group communication, thereby has guaranteed privacy.This is due to the fact that does not support the node (server or user terminal) of the interior private message of group communication will refuse the message that private message in the group communication is supported in requirement.
In another embodiment, device does not check whether message comprises as the indication of the mandatory header that requires to the support of private message in the group communication, but simply this header that requires is added into message.In other words, skips steps 405 is in step 404 back execution in step 403 or step 406.
The device of realizing the execution mode shown in Fig. 5 and Fig. 6 is arranged to the ability information of maintenance about chat room server.Ability information about chat room server can obtain during session is set up.For example, can use " isfocus " parameter of sending in the message during session is set up to obtain ability information about chat room server.
The execution mode of Fig. 5 has utilized the following fact: each message comprises subject header, and this subject header comprises that the sender is to the title of message or the description of content.
With reference to figure 5, step 501 arrives step 304 to step 504 corresponding to the step of above describing with reference to figure 3 301, no longer repeats here.
In the execution mode of Fig. 5, if next node is not supported privacy (step 504), then install in step 505 to check whether chat room server supports privacy, also be the private message in the group communication.If support, then install in step 506 and can add prefix to the subject header of instant message, such as " private (secret) ", to indicate this instant message is the private message that sends in group communication, will have the instant message of having revised subject header in step 507 then and be forwarded to next node.
If chat room server is not supported privacy (step 505), then install at this instant message of step 508 refusal, and preferably by to the sender of this instant message or be actually last node that Xiang Congqi receives message and send the sender that error message for example comes notification message, wherein error message preferably has explanation, for example " does not allow private message in this chat ".
In other words, in the execution mode of Fig. 5, based on the check result of the ability information of using next node, device is as getting off to handle detected private message: transmit this message according to the former state that receives; Perhaps the ability of chat room server is further checked, and according to a back check result of using the chat room server ability information, before transmitting this message, add indication (indicating this message is private message group communication in), perhaps refuse this instant message and also will refuse to notify the sender to the subject header of this message.
The advantage of the execution mode of Fig. 5 is that the recipient can understand the privacy and the sensitiveness of message.Another advantage is, only in chat room server is supported group communication under the situation of private message, this chat room server just receives private message, thereby has guaranteed that chat room server can not be transmitted to private message whole participants.Another advantage is, if chat room server is supported the private message in the group communication, then this private message will be delivered to the expection recipient, no matter and whether recipient's user terminal supports the private message in the group communication.
In another embodiment, device is arranged to checked before adding prefix whether subject header has comprised the prefix of indicating private message, and did not only add prefix under subject header comprises the situation of this prefix.
Fig. 6 shows another execution mode of device.With reference to figure 6, step 601 arrives step 304 to step 604 corresponding to the step of above describing with reference to figure 3 301, no longer repeats here.
In the execution mode of Fig. 6, if next node is not supported privacy (step 604), then install in step 605 to check whether chat room server supports privacy, also be the private message in the group communication.If support, then install in step 606 and revise message body, promptly, the actual content of instant message, to indicate this instant message is the private message that sends in the group communication, and this for example is by adding for example prefix to the beginning of message body, such as " from the private message of user NN " (NN represents the sender of message), then in step 607, will comprise the instant message of having revised message body and be forwarded to next node.
If privacy (step 605) is not supported in the chatroom, then install at step 608 refusal instant message, and preferably by to the sender of instant message or be actually last node that Xiang Congqi receives message and send the sender that error message for example comes notification message, wherein error message preferably has explanation, for example " does not allow private message in this chat ".
In other words, in the execution mode of Fig. 6, based on the check result of the ability information of using next node, device is handled detected private message as follows: transmit this message according to the former state that receives; Perhaps the ability of chat room server is further checked, and based on a back check result of using the chat room server ability information, before transmitting message, revise message body, to comprise this message of indication is the indication of private message, perhaps refuses this message and will refuse to notify the sender.
The advantage of the execution mode of Fig. 6 is that only under the situation of the private message in chat room server is supported group communication, this chat room server just receives private message, thereby has guaranteed that chat room server can not send to private message all participants.Another advantage is, if chat room server is supported the private message in the group communication, private message will be delivered to the expection recipient, and the recipient will understand the privacy and the sensitiveness of this message, no matter and whether recipient's user terminal supports the private message that group communication is interior.
In another embodiment, device is arranged to checked before transmitting message body whether message body has comprised the indication of private message, and did not only revise message body under it comprises the situation of this indication.
In another execution mode, device is arranged in response to guaranteeing that message body includes the indication of private message, guarantees that subject header also indicates private message.
In another embodiment, device can be arranged to guarantees private message except comprising as the indication of mandatory the requiring the header of the support of private message in the group communication, also comprises the message body of the subject header and/or the indication privacy of indication privacy.
Fig. 7 is the signaling process figure that the signaling example in the system that is configured according to the present invention is shown.This example shows following situation: after setting up group communication session, the user of user terminal UT-A wants the user to user terminal UT-B to send private message in the session.Therefore, and for for the purpose of clear, be not illustrated in for example session among Fig. 7 and set up during other participants' the signaling of group communication.
In this example, suppose that UT-A comprises the group communication client according to the service of OMA instant message transrecieving, so it supports the private message in the group communication; And UT-B comprises the group communication client according to PoC, so it does not support the private message in the group communication.And supposing that server A and server C serve according to the OMA instant message transrecieving provides group communication service, so it supports the private message in group communication; And server B provides group communication service according to PoC, so it does not support the private message in the group communication.Server A and server B provide the server of the access of chat room server (server A provides for UT-A, and server B provides for UT-B), and server C is actual chat room server.Should be noted that hereinafter in the example of message content, instant message transrecieving is " user agent " when being applied in its transmission request, and is " server ", and no matter instant message transrecieving is used where is positioned at when it sends response.
With reference to figure 7, the user of UT-A wants to set up group communication session with the group that comprises the user of UT-B.Therefore, UT-A sends message 7-1 to server A.Message 7-1 can be " SIP INVITE User-Agent:IM-client/OMA 1.0 ", also, is that to indicate user agent among the UT-A first be message according to the instant message transrecieving client of OMA standard 1.0.In response to receiving message 7-1, at point 702, server A is stored " it supports the private message in the group communication " conduct about the ability information of UT-A, and sends message 7-3 to corresponding chat room server (server C).Message 7-3 can be " SIPINVITE User-Agent:IM-serv/OMA1.0 ", also, is that to indicate user agent in the server A first be message according to the instant message transrecieving server of OMA standard 1.0.In response to receiving message 7-3, at a 7-4, server C stores " it supports the private message in the group communication " conduct about the ability information of server A, and sends message 7-5 to the server B of serving UT-B.Message 7-5 can be " SIP INVITEUser-Agent:IM-serv/OMA1.0 ", also be, be that to indicate user agent among the server C first be message (corresponding message will be transmitted to other group members from server C, but also not shown for clarity other group memberships) according to the instant message transrecieving server of OMA standard 1.0.In response to receiving message 7-5, server B sends message 7-6 to UT-B.This message can be " SIP INVITE User-Agent:PoC-serv/OMA2.0 ", also, is that to indicate user agent in the server B first be message according to the PoC server of OMA PoC standard 2.0.
In response to receiving message 7-6, invite to the user notification of UT-B, and in this example, the user wants to add group communication.Therefore, UT-B sends message 7-7 to server B.Message 7-7 can be " 200OK Server:PoC-client/OMA2.0 ", also, is that to indicate server among the UT-B first be message according to the PoC client of OMA PoC standard 2.0.In response to receiving message 7-7, server B sends message 7-8 to chat room server (server C).Message 7-8 can be " 200OK Server:PoC-server/OMA2.0 ", also, is that to indicate server among the server C first be message according to the PoC server of OMA PoC standard 2.0.In response to receiving message 7-8, at a 7-9, server C stores " it does not support the private message in the group communication " conduct about the ability information of server B, and sends message 7-10 to the server A of serving UT-A.Message 7-10 can be " 200OK Server:IM-serv/OMA1.0 ", also, is that to indicate server among the server C first be message according to the instant message transrecieving server of OMA standard 1.0.In response to receiving message 7-10, at a 7-11, server A is stored " it supports the private message in the group communication " conduct about the ability information of server C, and sends message 7-12 to UT-A.Message 7-12 can be " 200OK Server:IM-serv/OMA1.0 ", also, is that to indicate server in the server A first be message according to the instant message transrecieving server of OMA standard 1.0.
In some stage of group communication, the user of UT-A wants to send private message 7-13 to the user of UT-B.This message for example can be the MSRP message of the URI (unified resource identifier) that comprises UT-B but not comprise the MSRP message of the URI of group.In response to receiving message 7-13, at a 7-14, it is secret that server A detects this message, and at a 7-14, checks whether server C supports the private message in the group communication, and in this example, check result is " yes, its support ".Therefore, server A is transmitted message 7-13.In response to receiving message 7-13, at a 7-15, it is secret that server C detects this message, and at a 7-15, checks whether server B supports the private message in the group communication, and in this example, check result is " no, it is not supported ".Therefore, server C refuse information 7-13, and send the message 7-16 notify this refusal to server A.Message 7-16 can be " 403 forbid (Forbidden) ", it comprises the reason of refusal, for example " network node in the path is not supported private message ", perhaps " target receiver is not supported the private message in the group communication " perhaps " can't be delivered to target receiver with the private message in the group communication ".Server A is forwarded to UT-A with message 7-16, and it can show this refusal and reason to the user.
