Requesting terminal 103 can receive key and/or additional informations from MGM server 101 by access point 105. and the requesting terminal can be transmitted to this key and/or additional information the message that one or more terminals 103. will multicast subsequently can task MGM server 101 in 105 minutes by access point by terminal 103, by the MGM server for encrypting, put 107 multicasts to receive by multicast subsequently by suitable terminal 103. multicast point 107 for example can be a unidirectional multicast point, DVB-T (digital video broadcasting-land) for example, DVB-S (digital video broadcasting-satellite) or DAB (digital audio broadcasting) multicast point. in various embodiments, multicast point also can use the bidirectional technique such as UMTS.
Should be pointed out that in various embodiment of the present invention, for example may exist, can have a plurality of unit 101-107. than more or less terminal 101-107. of Fig. 1 example
Now, various aspects of the present invention will be described in more detail.
Message transmits the request that is provided with
The terminal that the user who wish to initiate the MGM session can use her is sent this request to MGM server etc. and this request can comprise some regulation, MGM session desirable start and end time for example, suggestion or the regulation of message with the message transfer address of carrying out multicast and being set up submitted in the regulation or the suggestion of zone that should receiving multicast message, the encryption type that should use in multicast message and/or should be to. and according to various embodiments of the present invention, exist the user request can be submitted to the multiple mode of suitable server.
According to some embodiment, the user can be by manually foundation and assignment message submit request to for suitable Email, SMS (short message service), MMS (multimedia messaging service) or other message transfer address.For example, can stipulate should be with such request as sensing
MGMsetup@messaging.serviceprovider.comSMS message assign.
Such request may require to have certain form. for example, can require this request message to comprise that form is the delegation or the multirow of " attribute: numerical value ", wherein have a plurality of acceptable attribute keywords and acceptable respective value or numerical range. for example, an attribute can be " start time ". analog value may be prescribed as " dd.mm.yyyy; Hh:nn; Zzz " form; wherein " dd " is corresponding to standard two numerals of certain per medio; " mm " is corresponding to standard two numerals in month; " yyyy " is corresponding to standard four numerals in time; " hh " corresponding to hour standard two numeric representations; " nn " corresponding to minute standard two numerals, " zzz " represents corresponding to the standard three-character doctrine in time zone. therefore, wish request in the user of the Central European Time MGM that 1:36 begins in afternoon on October 23rd, 2005 can the request message at her, comprise row " 10.23.2005; 13:36; ECT ".Can set up similar attribute and analog value for the explanation of aforesaid other kind, for example zone or conversation end time.
Also can be alternatively or additionally allow such manual request with the form of free-format and/or natural language.In this case, can require the user to indicate some message unit (for example MGM session start time), but can select her presentation format.Therefore, the request in comprise " I wish this afternoon 12:23 begin " can be the explanation of acceptable start time.
Except manual submission the to of MGM conversation request, embodiments of the invention can be additionally or are alternatively allowed the user to submit conversation request to by the interface. and under situation about submitting to by the interface, one or more representation program modules of working on user terminal for example can show that the user can be used to submit to the graphic user interface (GUI) of the information needed relevant with her MGM request.
For example, one or more representation modules can represent that the user can be in order to select the GUI such as start time, concluding time and zone that should receiving multicast message etc.GUI can also allow the user to select and/or specify the one or more MGM servers that request should be submitted to etc.Showing to the user when wherein selecting the tabulation of one or more take over party MGM servers etc., for example can fill described tabulation by making the supplier who inserts these information in one or more discovering server program modules of working on the terminal. during at access provider, described module can be used SOAP (Simple Object Access Protocol), JMS (Java messaging delivery services) or RMI (remote method invocation (RMI)) etc.
After the essential information of placing, one or more request dispatch program modules of working on this terminal can be transmitted to this request one or more suitable MGM servers etc. be collected in the MGM request from the user by the interface in. and this can carry out in several ways.For example, one or more request dispatch program modules can be encoded into text message with the information of collecting from the user, and by Email, SMS or MMS etc. this message branch are tasked suitable server.This coding for example can use XML (extensible markup language).Above-mentioned functions for example is being provided, and the user can be manually submits among the embodiment of MGM solicited message in SMS message etc. thus, one or more program modules message with arbitrary prescribed form compatibility of can encoding.This prescribed form for example can be used above-mentioned " attribute: numerical value " form.
As the another one example, one or more request dispatch program modules can will send suitable MGM server etc. from the information that the user collects to by SOAP, JMS or RMI etc.
Message transmits and is provided with
As shown in Figure 2, aforesaid MGM server etc. can receive the MGM conversation request (step 201) that comprise a plurality of explanations from terminal.
Receiving under the situation of conversation request by SMS message, MMS message or the email message etc. that point to the particular message transfer address relevant with server, the one or more requests that move on server receive program module and can be used for being extracted in the explanation (step 203) that wherein comprises from this message.
Under situation about by the form of stipulating explanation being coded in the message, these one or more request receiver modules can be used for extracting explanation according to this form. for example, in explanation is under the situation of above-mentioned " attribute: numerical value " form, one or more modules can scan defined attribute and write down corresponding numerical value in input message. in request, lose under one or more essential message units or its a part of situation, may by with the identical transmission method of the transmission method that is used to assign conversation request (for example SMS), error message returned to submits user and/or terminal to.
Selectively, the request receiver module can attempt to guess the data of losing. for example, if with hour and minute the expression start time, but there is not the expression in date or time zone, then module can suppose that the time zone is user's a local time zone. in addition, the represented time under situation about not arriving as yet the same day, otherwise it is the same day that this module can be supposed the unspecified date., the represented time under the same day over and done with situation, can suppose that the date is next day. under the situation of drop-out, module can not guess or the situation of satisfied conjecture under or do not carry out among the embodiment of such conjecture function in module, can error message be returned to request user and/or terminal by above-mentioned similar mode.
Under the situation of user with free-format and/or not building mode input explanation, one or more request receiver modules can use at natural language explanation well known in the art and/or analytical technology and be extracted in the explanation that comprises in this message.Because the free-format attribute of such request, the user can be deliberately or is by mistake omitted some information.For example, the user of regulation start and end time can omitted date, time and time zone, believes that perhaps these are original like this or conspicuous. and in certain embodiments, request processing module can attempt to guess obliterated data as described above.Under the situation of drop-out, module can not guess or the situation of satisfied conjecture under, perhaps do not carry out among the embodiment of such conjecture function in module, can error message be returned to request user and/or terminal by above-mentioned similar mode.
In module by on terminal, moving, may message unit be sent under the situation of server via SOAP or JMS etc., the request interface module of moving on this terminal can directly receive the unit that is transmitted, and does not need analysis of carrying out mentioned kind etc.
In case had the explanation of MGM conversation request by one of mode of just having described, then ask receiver module this explanation can be stored in (step 205) in the relevant storer. can also store at this and send requesting users and/or terminal representing. this expression for example can be user's MMS address. this for example can be by checking the head of conversation request message, perhaps by analyze SOAP, JMS, RMI or similarly communication determine. can handle by one or more request handler module of on MGM server etc., moving subsequently in the project of store memory storage.
As the first step, one or more request handler module can be used for determining multicast address, multicast IP (Internet Protocol) address for example, in multicast group message transmits, to use (step 207). this multicast address for example can be selected from available multicast address pond, in case may wish the MGM conversation end of being asked then this address is returned to this pond. and one or more request handler module can be considered one or more explanations that receive when selection from this pond.For example, in case can consider start time, concluding time and/or zone. selected multicast address, then one or more request handler module can be deleted this address from the available address pond.
As next procedure, one or more request handler module can be set up the message transfer address that is used to receive message that will multicast, for example e-mail address, SMS address or MMS address (step 209). one or more request handler module can be selected described message transfer address from pond, available message transfer address. and comprise in the explanation that is received under the situation of user's suggestion of message transfer address, module can consider when select the message transfer address from described pond.For example, if exist the message transfer address to comprise the suggestion of phrase " game chat ", then these modules can be sought the available message transfer address that comprises this phrase or this phrase of close match.
From the pond, do not select the message transfer address, one or more request handler module can newly be set up the message transfer address. and under the situation of the user of the message unit regulation message transfer address that is received suggestion and/or explanation, newly-established message transfer address can be according to this explanation and/or suggestion.When setting up new message transfer address, one or more request handler module can be taken steps, so that the message of refer message transfer address will be received by the MGM server, in case and/or have the suitable message of on integrated and/or discrete SMS server or MMS server, setting up and transmit counting. one or more request handler module also can be taken steps so that MGM conversation end then delete this counting from suitable MMS server etc.
As next procedure, one or more request handler module can be stipulated the relation (step 211) between multicast address and the message transfer address in relevant storer. then, one or more request handler module can be determined the timetable (step 213) of multicast in the MGM session. for example, can determine to occur in per five minutes that multicast will be in one hour (5:05pm for example, 5:10pm, 5:15pm, Deng). when in hope is being wanted according to the terminal of MGM session receiving group, promoting energy-efficient, can determine such timetable, because terminal may only need monitor the transmission that arrives in the time of plan.
The definite of timetable can consider for example energy operating characteristic of exemplary terminal in for one or more zones of MGM session regulation.For example, by considering ISP's record of the universal situation of expression particular terminal model in zones of different, and further consider the manufacturer technical descriptioon relevant, can know such characteristic with these terminal models.
Then, the key (step 215) that will use during the message of multicast in deciphering can be selected or set up to one or more request handler module in the MGM conversation procedure. and module can also be selected the encryption method that will use.Selectively, can always be to use a kind of encryption method. the selection of the selection of key and/or foundation and/or encryption method also can be considered multiple factor.These factors can be included in the suggestion encryption method that comprises in the explanation that is received.
As next procedure, the session information relevant with message transfer address, multicast address, timetable, key, algorithm and/or out of Memory of MGM session can be by these module stores in the storer relevant with server, and/or is transmitted to the user and/or the user terminal (step 217) of this MGM session of request.In various embodiment of the present invention, module can only be transmitted to this session information the user and/or the user terminal of request MGM session.
Can transmit in many ways.For example, information can be placed in the MMS message, SMS message, email message etc. of the user that point to assign the MGM conversation request and/or user terminal, directly to read by the user.As another example, this information can be used codings such as XML, perhaps is placed in the MMS message etc. of directed towards user or her terminal.As another example, can send information on user terminal, work one or more software modules by SOAP, JMS or RMI etc.
The terminal of MGM session information receives and transmits
Receive the information relevant in case assign the terminal of MGM conversation request from the MGM server with this session, then the one or more of some actions may be taken place. for example, as shown in Figure 3, by the message browser program module of on terminal, moving, the session information that points to this terminal user be can extract in a usual manner and MMS message or email message etc. carried, directly to read (step 301) by the user. the user can use one or more modules to read this message, and can be recorded in the session information that wherein comprises. if desired, the user can offer the information that is write down suitable (steps 303) such as program modules moved on terminal.
Except the user browses message and/or is recorded in the session information that wherein comprises, perhaps browse message as the user and/or be recorded in the alternative of the session information that wherein comprises, one or more MGM session information extraction procedure modules of operating on this terminal can be moved to extract session information from this message.These modules can write down this information, and/or as describing in more detail hereinafter, sending it to one or more suitable program module of on this terminal, operating etc. this program module can be known the MGM server in order to coding session information one or more forms directly to be read by the user, and can use this knowledge extracting session information from this message.Selectively, these modules can be used the session information of these message of analysis such as natural language analysis technology that are known in the art.
In order to handle MMS message or the email message etc. of receiving that comprise not the MGM session information of special coding in order directly to be read by the user, the session information extraction module can be with described similar fashion executable operations just now.Such message for example can be the message that comprises the session information of encoding in the mode of using XML.As mentioned before, these modules may be known one or more forms that the MGM server uses in the coding session information, and can use this knowledge when extracting session information.Except record and/or transmit the MGM session information or as a kind of alternative, these modules can be shown to the user with session information, may pass through the GUI dialog box.The user can write down this information and/or this information offered proper procedure module of moving etc. on terminal.
MGM session information branch is tasked under the situation of terminal by SOAP, JMS or RMI etc. at the MGM server, the session information extraction module can receive this information. to be similar to above-mentioned mode, module can be carried out to write down this information, and/or it is sent to one or more suitable program module of on terminal, moving etc. selectively or additionally, this module can be shown to the user with information.
Should also be pointed out that, in case on the requesting terminal, receive the MGM session information, can take action this session information is transmitted to one or more other terminals. can carry out this forwarding in many ways. for example, under the user receives comprising the situation of session information with the MMS message that directly reads or email message etc., the user can give one or more other users and/or terminal with this forwards, may use the message convey program module of moving on terminal (step 309).
The user can be mutual with module by GUI or voice control etc. by GUI dialog box etc. under the situation of user's display session information, dialog box etc. can provide execution with the selection of this forwards to designated user and/or terminal.In certain embodiments, can the configuration messages delivery module whether can further transmit this message (step 305) with the recipient who allows message that regulation is transmitted. the user for example can by GUI be provided with this option .GUI can be used to select the GUI that transmits identical. should not allow in regulation under the situation of further forwarding, module can be given the message of being transmitted (step 307) with such indication interpolation. in such embodiments, can be configured in the program module of operating on the terminal considering such designator, so that will not allow the user to transmit to have the message of such indication.
In a similar fashion, in various embodiments, can show to the user and transmit the option comprise the MMS message of using formative session informations such as XML or email message etc. for example, the user and/or the terminal that can further allow the user to specify this information to be transmitted to the GUI dialog box of user's display session information.As mentioned above, in certain embodiments, can show the option that does not allow further to transmit message to the user.
And, in a similar fashion, in various embodiments, can show the option of forwarding to the user by the MGM session information of receptions such as SOAP. such embodiment can provide the interface such as the GUI dialog box, and the user can specify the user and/or the terminal that should receive this information by it.To be similar to above-mentioned mode, can show that the terminal prevent to receive the session information of being transmitted is further with the option of its forwarding to the user. the module of moving on terminal can be carried out by SOAP etc. session information branch being tasked the user and/or the terminal of appointment, and described session information may have the indication that not allowing of being added further transmitted.
In case terminal receives the MGM session information of transmitting from another terminal, can carry out with top reference terminal and receive the similar action of the described action of session information from the MGM server. for example, can show the session information of being transmitted to the user of receiving terminal by dialog box etc., and can and/or send to the program module of on this terminal, moving the session information record transmitted.As another example, do not allow further to transmit under the situation of the forwarding session information that is received in regulation not, can show the option that session information further is transmitted to other terminal and/or user to receiving the user.
Can also be to receiving recipient that the user shows whether regulation allow the new information of transmitting further with the option of its forwarding. the terminal and/or the user that receive the new session information of transmitting can be similarly to the one or more above-mentioned actions of this information and executing.
Message multicast
As shown in Figure 4, hope can be carried out the message transfer address of being set up so that this message branch is tasked corresponding with this session (for example SMS address) (step 401) by the user of MGM conversation group broadcast message. and the user can call and the relevant new message composition window of message delivery module of operating on its terminal, and these modules can be associated with the message dispatcher such as routines such as MMS, SMS or E-mail clients.Can show to the user can press with the GUI button that starts composer window etc. and this button can have the label such as " click this sentence give MGM session x with message multicast ", wherein can use the identifier relevant with the MGM session to substitute " x ".
The user can be by the component units of new composer window to message interpolation such as text, file, figure, sound and film etc. should be understood that some embodiments of the present invention can limit the cell type that can add to message. for example, in certain embodiments, may only allow to add text.
After finishing message composition, the user can specify the message that will assign.The user for example can carry out this operation by being input in the GUI field relevant with this composer window for the message transfer address that this MGM session is set up.Subsequently, the user can press " transmission " GUI button relevant with this window.This message branch is tasked the message transfer address can be according at the transmission method that is used for this message transfer address type (for example SMS) well known in the art.
Should be pointed out that in certain embodiments the user may not need to specify the message transfer address of being set up. for example, the software module of moving on terminal etc. has been known in the foregoing description of the session information that is received, may has been this situation.Should also be pointed out that can provide function so that by can consider the start and end time of session in the software module of wishing to move on the user terminal of multicast message. for example, software module can prevent the foundation of the message in the multicast in session and/or transmission, represents that up to start and end time this session is movable or to be about to be movable.
In case on MGM server etc., receive will multicast message, one or more propagation module of operating on server can at first be determined the message transfer address (step 403) that this message mails to. then, these modules can be visited above-mentioned storer, thereby determine the MGM session (step 405) relevant with this message transfer address.
After this, these modules can determine whether this session is movable (step 407). relevant with server and/or can be by inquiry by the clock of server access and/or calendar with definite current time and/or date, the consulting storer is to determine the start and end time relevant with this session, and determine that current date and/or time are whether in the time cycle of this session and/or just before the time cycle of this session, can carry out aforesaid operations. finding that the MGM session is not under the situation of activity, this terminal can stop the further processing to arrival message, and SMS message etc. can be sent to terminal and/or user's (step 409) of the message that assignment will multicast.The message that is sent for example can stipulate that session is expired.
