Description

A kind of method of business transferring information and device

Technical field

The present invention relates to wireless communication field, particularly relate to a kind of method and device of business transferring information.

Background technology

In communication network, user's input information is also initiated a communication request, and the request purpose is generally following three kinds:

1, in order to establish a communications link with another user, then asking point of destination is the request purpose user ID that the user imports.

2, in order to use a kind of business, then asking point of destination is the service identification that the user imports, its expression be the sign of business/service of providing of network.

3, in order to use a kind of business, request and user establish a communications link or operate user service data etc. simultaneously, and then to ask point of destination be the service identification of input and ask professional satellite informations such as purpose user ID and user service data.

As seen, the user need provide service identification and professional satellite information usually simultaneously in order to use a kind of business.

Session Initiation Protocol is a kind of application layer control protocol that is used to set up, change and stop Multimedia session or calling, and described Multimedia session or calling comprise: multimedia conferencing, remote teaching, Internet telephony etc.The user uses Session Initiation Protocol to initiate a communication request, and the request purpose is arranged on the Request-URI of the request row (Request-Line) of request message (in the request-URI).According to the SIP standard agreement, described Request-URI can carry user ID or service identification (in some communication network that uses Session Initiation Protocol, service identification is also referred to as PSI), but Request-URI does not support to carry simultaneously service identification and user ID.

At present in the SIP standard agreement, the method of carrying service identification and user ID in a communication request message simultaneously is: carry the request purpose user ID as professional satellite information in Request-URI, service identification and other professional satellite information are then indicated by different header fields or incident bag.Because business demand can't predict in advance, if new business just increases a kind of new header field or the incident bag is indicated, this obviously is not a universal scheme.

Summary of the invention

The invention provides a kind of method and device of business transferring information, do not have a kind of universal scheme can in sip message, carry the problem of service identification and professional satellite information simultaneously at present in order to solve.

The inventive method comprises the following steps: business information is carried in the fix information section of sip message; Described sip message is mutual between sip user agent, to realize the transmission of business information.

The present invention initiates the user terminal apparatus of service requesting information, comprising: the service requesting information boundary element, but be used for providing the operation interface of incoming traffic solicited message to the user; The service requesting information receiving element is used to receive the service requesting information that the user imports on the operation interface that the service requesting information boundary element provides; The service requesting information transmitting element is used for the service requesting information that the service requesting information receiving element receives is configured to the fix information section of sip message, and sends this sip message.

Beneficial effect of the present invention is as follows:

The present invention does not re-use different header fields or the incident bag is indicated different business, but business information is carried in the fix information section of sip message.Promptly still can utilize Request-URI to carry service identification and/or request purpose user ID, other business information is all by logic fix information section (information input parameter, information input header field, information incoming event bag, perhaps information is imported body) carry, and discern different business according to service identification by service control network element.By enforcement of the present invention, need not be when Added Business corresponding increase header field or incident bag, thereby the inventive method can be used as compatible all professional general schemes, and meets the SIP standard agreement.

Fig. 2 initiates the structural representation of the user terminal apparatus of service requesting information for the present invention.

Embodiment

Corresponding for fear of class of business with header field or incident bag, the invention provides a kind of method of general business transferring information, referring to shown in Figure 1, comprise following key step:

S1, business information is carried in the fix information section of sip message.

S2, described sip message is mutual between user agent (SIP UA, User Agent) is to realize the transmission of business information.

S3, provide related service for the user according to the business information of transmitting.

Wherein, business information described in the step S1 comprises: service requesting information, service announcements information and service interworking information, below at service requesting information enforcement in the present invention, and service announcements information and the enforcement in the present invention of service interworking information are described in detail respectively.

● details are as follows at service requesting information.

Service requesting information comprises service identification and professional satellite information.

The present invention with service identification and professional satellite information be carried in the sip message one or more and by in the shared fix information section of different business, described fix information section comprises: Request-URI message segment and at least one other fixed position (logic fix information section).There are three kinds of situations in carrying of described service identification and professional satellite information:

Situation one: the Request-URI message segment in the sip message is carried described request purpose user ID; And the logic fix information section in the sip message is carried at least one service identification.

Situation two: the Request-URI message segment in the sip message is carried service identification; And the logic fix information section in the sip message is carried at least one professional satellite information.

Situation three: the Request-URI message segment in the sip message is carried described request purpose user ID and service identification.Be the domain name prefix of described service identification as request purpose user ID.

In above-mentioned three kinds of situations, described logic fix information section can be uri-parameters parameter, header field (header), the incident bag (eventpackage) in the request row (Request-Line) in the sip message, perhaps message body (message body).

At described uri-parameters parameter, can in the uri-parameters of sip message parameter, define an information input parameter, as: called after info-input-param, to carry business information.

At described header field, can in the header field of sip message, define an information input header field, as: called after Info-Input, to carry business information.

At described incident bag, can in the incident bag of sip message, define an information incoming event bag, as: called after info-input, carry business information with the parameter of information incoming event bag.

At described message body, can in the sip message body, define an information input medium type (mediatype), form is the MIME medium type, as: called after application/info-input, carry business information by this information input body (body).

Above-mentioned logic fix information section is a logical definition, it can be uri-parameters parameter, header field, incident bag or the message body application of the new expansion of definition in Session Initiation Protocol, also can be that existing uri-parameters parameter in the Session Initiation Protocol, header field, incident bag or message body Application Expansion are used; Also can further distinguish the logic fix information section of carrying service identification and the logic fix information section of professional satellite information, as: service identification input header field and professional satellite information input header field, service identification incoming event bag and professional satellite information incoming event bag, service identification input body and professional satellite information input body etc., also can in logic fix information section, carry service identification and professional satellite information, can certainly not distinguish by the different parameters differentiation.

Three kinds of situations that the service identification in the corresponding service requesting information and the mode of carrying of professional satellite information exist below specifically describe the inventive method by three examples.

Method example one: Request-URI carries request purpose user ID, and service identification is carried in the logic fix information section.

In the present invention, service identification can be a SIP URI form, as " sip:conference-factory@home.net " expression convention business sign, " sip:200@home.net " or " sip:prepaid-card@home.net " expression pre-payment card number service identification; Can also be tel URI form, as " tel:200; Phone-context=home.net " expression 200 card number service sign; Can also only be a domain name, omit user profile (userinfo) and " " symbol, as " sip:prepaid-card.com " expression pre-payment card number service identification; Can also be that traditional telephone number is the service feature coding mode, as " 200 " expression 200 card number service sign; Can also be the character string of describing service feature/attribute, as " prepaid-card " expression pre-payment card number service identification.

In above-mentioned information input parameter or information input header field or information incoming event bag or information input body, can only carry a service identification, also can carry more than one service identification, promptly the user can ask a plurality of business in order.

The use of several typical services is described respectively below:

1, freephone

User A initiates a calling, and the expense that requires this calling to take place is born by called, and example is as follows:

INVITE?sip：mary@home.net；info-input-param＝800?SIP/2.0

Perhaps,

INVITE?sip：mary@home.net；info-input-param＝reverse-charging?SIP/2.0

Perhaps,

INVITE sip：mary@home.net；

info-input-param＝<sip：reverse-charging@home.net>SIP/2.0

Perhaps,

INVITE?sip：mary@home.net；info-input-param＝<sip：reverse-charging.com>SIP/2.0

Wherein, " sip:mary@home.net " is the CSI called subscriber identification of SIP URI form, be the purpose user ID of this call request, the different-format of " 800 " or " reverse-charging " or " sip:reverse-charging@home.net " or " sip:reverse-charging.com " expression freephone sign.Network is received this calling, will identify according to freephone, indicates this calling charge to be born by the called subscriber to charge system.

The example of carrying the freephone sign by information input header field or information incoming event bag or information input body is as follows respectively:

INVITE?sip：mary@home.net?SIP/2.0

Info-Input：800

Perhaps,

INVITE?sip：mary@home.net?SIP/2.0

Subscription：info-input；service-id＝800

Perhaps,

INVITE?sip：mary@home.net?SIP/2.0

Content-Type：application/info-input

service-id＝800

Wherein, " service-id " is the parameter of being responsible for the business transferring sign in information incoming event bag or the information input body, can see, identify and professional satellite information (can certainly not distinguish) by the different parameters differentiated service in information incoming event bag or the information input body in the example, then do not have differentiated service sign and professional satellite information (can certainly distinguish) in information input parameter or the information input header field.

Adopted the form of the freephone sign of " 800 " above, also can adopt other above-mentioned form, example slightly.

2, convention business

User A initiates a calling, requires this calling to add meeting, and example is as follows:

INVITE?sip：mary@home.net；info-input-param＝conference-factory?SIP/2.0

Wherein, " sip:mary@home.net " is the CSI called subscriber identification of SIP URI form, and " conference-factory " identifies convention business, adopts the example of the convention business sign of other form to omit.Network is received this calling, will identify according to convention business, and the application conferencing resource, and set up the meeting passage between the user A, and the called subscriber is also added this meeting, set up Conference Calling thereby make between user A and the called subscriber.

Perhaps, user A makes a call as user B, user C to several users, requires these users to add meeting together, and example is as follows:

INVITE?sip：group-list1@home.net；info-input-param＝conference-factorySIP/2.0

Wherein, " sip:group-list1@home.net " is with user B and the user C group identification as a group/set, the user B sign and the user C sign of its correspondence can be arranged in the network in advance, also can be carried in this call request message (SIP INVITE invitation message), as in this message body, describing by XML form or other parameter format.Network is received this calling, to identify according to convention business, the application conferencing resource, and set up the meeting passage between the user A, and according to above-mentioned group identification, obtain corresponding, be arranged in the network in advance or be carried on user B sign and user C sign in the message, respectively user B and user C are added this meeting again, set up Conference Calling thereby make between user A and user B, the user C.

The example of carrying the convention business sign by information input header field or information incoming event bag or information input body is as above similar, and example slightly.

3, user service data operation

User A initiates a calling, requires the user service data of calling forwarding on busy is set, and example is as follows:

INVITE?sip：rose@home.net；info-input-param＝*40*26500000SIP/2.0

Or user A also can finish the setting of the user service data of calling forwarding on busy by initiating a subscribe request, and example is as follows:

SUBSCRIBE?sip：rose@home.net；info-input-param＝*40*26500000?SIP/2.0

Wherein, " sip:rose@home.net " is the user ID of user A oneself, i.e. the purpose user ID of this communication request (purpose that user A initiates communication request is the user service data of operation oneself); " * 40*26500000 " then comprised service identification " * 40 " and as the destination address of calling forwarding on busy " 26500000 " of the professional satellite information of another kind, promptly do not had differentiated service sign and professional satellite information in this example, can certainly distinguish.

The example of carrying the convention business sign by information input header field or information incoming event bag or information input body is as above similar, and example slightly.

This routine special place is in addition, in the logic fix information section except carrying service identification, also need to carry user service data (destination address of calling forwarding on busy) as professional satellite information, in fact, because Request-URI has carried the request purpose user ID as professional satellite information, obviously if also have the professional satellite information of other type in certain professional use, then need to carry by described logic fix information section, freephone as the aforementioned, can also carry a satellite information, whether indicate the use of this freephone to need and called negotiation (because called use of perhaps disagreeing with this business), example is as follows:

INVITE?sip：mary@home.net?SIP/2.0

Info-Input：800；reverse-charging-consulting＝true

Wherein, " reverse-charging-consulting " expression freephone whether will with called negotiation parameter, parameter is set to " true " expression to be needed and called negotiation.

For another example, to aforesaid convention business, can also carry other satellite information, indicate each meeting authority that adds the user of meeting (as the meeting control authority, can listen talkative meeting participant, the meeting participant that can only listen etc.) and user's said language etc., example is as follows:

INVITE?sip：group-list1@home.net?SIP/2.0

Content-Type：application/info-input

service-id＝conference-factory

user＝<sip：mary@home.net>；rule＝only-listen；language＝english

user＝<sip：alice@home.net>；rule＝listen-speak；language＝french

Wherein, the user B of group identification correspondence and the user ID of user C are carried in the call request message, be respectively " sip:mary@home.net " and " sip:alice@home.net ", and " rule " expression user's meeting authority, " only-listen " expression can only be listened, and " listen-speak " expression can be listened talkative; And the said language of " language " expression user, " english " represents English, " french " represents French.

Method example two: Request-URI carries service identification, and professional satellite information is carried in the logic fix information section.

In this example, owing to service identification is carried by Request-URI, so it can only be the URI form.

Similarly, in information input parameter or information input header field or information incoming event bag or the information input body, can only carry a professional satellite information, also can carry more than one professional satellite information.

The use of several typical services is described respectively below:

1, freephone

User A initiates a calling, and the expense that requires this calling to take place is born by called, and example is as follows:

INVITE sip：reverse-charging@home.net；

info-input-param＝<sip：mary@home.net>SIP/2.0

Perhaps,

INVITE?sip：800@home.net；info-input-param＝<sip：mary@home.net>SIP/2.0

Perhaps,

INVITE tel：800；phone-context＝home.net；

info-input-param＝<sip：mary@home.net>SIP/2.0

Perhaps,

INVITE?sip：reverse-charging.com；info-input-param＝<sip：mary@home.net>SIP/2.0

Wherein, " sip:reverse-charging@home.net ", " sip:800@home.net ", " tel:800; Phone-context=home.net ", " sip:reverse-charging.com " be the freephone sign of URI form, " sip:mary@home.net " is the CSI called subscriber identification as professional satellite information.

Carry as the example of the CSI called subscriber identification of professional satellite information as follows respectively by information input header field or information incoming event bag or information input body:

INVITE?sip：reverse-charging@home.net?SIP/2.0

Info-Input：<sip：mary@home.net>

Perhaps,

INVITE?sip：reverse-charging@home.net?SIP/2.0

Subscription：info-input；service-param＝<sip：mary@home.net>

Perhaps,

INVITE?sip：reverse-charging@home.net?SIP/2.0

Content-Type：application/info-input

service-param＝<sip：mary@home.net>

Wherein, " service-param " is the parameter of being responsible for the business transferring satellite information in information incoming event bag or the information input body, with example class in the method example one seemingly, identify and professional satellite information (can certainly not distinguish) by the different parameters differentiated service in information incoming event bag or the information input body in the example, then do not have differentiated service sign and professional satellite information (can certainly distinguish) in information input parameter or the information input header field.

Adopted the form of the freephone sign of " sip:reverse-charging@home.net " above, also can adopt other above-mentioned form, example slightly.

And to aforesaid freephone whether will with the satellite information of called negotiation, as follows in the example of method example two:

INVITE?sip：reverse-charging@home.net?SIP/2.0

Info-Input：<sip：mary@home.net>；reverse-charging-consulting＝true

2, convention business

User A initiates a calling, requires this calling to add meeting, and example is as follows:

INVITE sip：conference-factory@home.net；

info-input-param＝<sip：mary@home.net>SIP/2.0

Wherein, " sip:conference-factory@home.net " is the convention business sign, general, the meeting network element address that convention business is controlled is handled in just providing of its sign, adopt the example of the convention business sign of other form to omit, " mary@home.net " is the CSI called subscriber identification as professional satellite information.

Perhaps, user A makes a call as user B, user C to several users, requires these users to add meeting together, and example is as follows:

INVITE sip：conference-factory@home.net；info-input-param＝<sip：group-list1@home.net>SIP/2.0

Perhaps,

INVITE sip：conference-factory@home.net；

info-input-param＝<sip：mary@home.net>，<sip：alice@home.net>SIP/2.0

Wherein, the information input parameter can carry expression user B and the user C group identification " sip:group-list1@home.net " as a group/set, also can carry user B sign and user C sign: " sip:mary@home.net " and " sip:alice@home.net ", promptly can carry more than one professional satellite information.

Perhaps, user A and user B are in conversation, and user A request should be conversed and be added meeting, and example is as follows:

INVITE sip：conference-factory@home.ne；info-input-param＝7sdjfkj2356，to-tag＝xyz，from-tag＝pdq?SIP/2.0

Wherein, " 7sdjfkj2356 ", " xyz " and " pdq " have represented dialogue (dialog) sign of above-mentioned conversation of having set up together, this dialogue identifier can uniquely be determined a conversation, owing to the conversation of appointment will be added meeting, therefore must carry dialogue identifier as professional satellite information, and the user ID (because this moment, user B may set up a plurality of conversations) that can not carry user B.

The example of carrying the convention business sign by information input header field or information incoming event bag or information input body is as above similar, and example slightly.

And to the satellite information of aforesaid users conference authority and the said language of user, the example of employing method example two is as follows:

INVITE?sip：conference-factory@home.net?SIP/2.0

Content-Type：application/info-input

user＝<sip：mary@home.net>；rule＝only-listen；language＝english

user＝<sip：alice@home.net>；rule＝listen-speak；language＝french

3, user service data operation

User A initiates a calling, requires to be provided with the user service data of calling forwarding on busy, the destination address of promptly calling forwarding on busy, and example is as follows:

INVITE sip：telecommunication-service@home.net；

info-input-param＝*40*26500000?SIP/2.0

Wherein, " sip:telecommunication-service@home.net " represents telecommunication services identification, " * 40*26500000 " is the user service data that comprises the destination address of calling forwarding on busy (26500000), here more special is, because it is to the professional data setting of calling forwarding on busy that the service identification (" sip:telecommunication-service@home.net ") that Request-URI carries does not directly go out to orient this, therefore still need to carry the call forwarding on busy information (" * 40 ") of service attribute of expression in the information input parameter, promptly in method example two, logic fix information section also can be carried service identification.

If the service identification that Request-URI carries can directly be oriented the business of calling forwarding on busy, then the information input parameter can only carry user service data, and example is as follows:

INVITE?sip：cfb@home.net；info-input-param＝26500000?SIP/2.0

Perhaps,

INVITE?sip：*40@home.net；info-input-param＝26500000?SIP/2.0

Perhaps,

INVITE?tel：*40；phone-context＝home.net；info-input-param＝26500000?SIP/2.0

Wherein, " sip:cfb@home.net ", " sip:*40@home.net ", " tel:*40; Phone-context=home.net " the expression service identification of calling forwarding on busy.

In addition, user A also can finish the setting of the user service data of calling forwarding on busy by initiating a subscribe request, and example is as follows:

SUBSCRIBE?sip：cfb@home.net；info-input-param＝26500000?SIP/2.0

The example of carrying the convention business sign by information input header field or information incoming event bag or information input body is as above similar, and example slightly.

4, messaging service

User A initiates a messaging service request, sends SIP MESSAGE message, and example is as follows:

MESSAGE?sip：message-center@home.net?SIP/2.0

--boundary1

Content-Type：application/info-input

user＝<sip：mary@home.net>

--boundary1

Content-Type：text/plain

Hello?World！

--boundary1

Wherein, " sip:message-center@home.net " is the messaging service sign, general, the message center network element address that just provides the professional control of processing messages of its sign, this message is required to mail to request purpose user ID " sip:mary@home.net ", and message content is " the Hello World! of text formatting ".

Method example three: Request-URI carries request purpose user ID and service identification simultaneously.

In the prior art, when Request-URI carries request purpose user ID, its form generally all has " domain name " information, " home.net " in the example is exactly a domain name as described above, if add the prefix of an expression service identification before the domain name of request purpose user ID, then Request-URI just can carry request purpose user ID and service identification simultaneously, as convention business, user A initiates a calling, requires this calling to add meeting, and example is as follows:

INVITE?sip：mary@conference.home.net?SIP/2.0

Wherein, " sip:mary@conference.home.net " is the domain name prefix " conference " that has added in request purpose user ID " sip:mary@home.net " as service identification, network is received this calling, to identify according to convention business " conference ", the application conferencing resource, and in the time will asking the purpose user to add meeting, delete this domain name prefix, make a call to request purpose user:

INVITE?sip：mary@home.net?SIP/2.0

Also can be to manage business the network element that triggers in the network when according to the convention business sign this calling being toggled to the network element of handling convention business, just delete this domain name prefix, the calling that the network element of handling convention business is received be as follows:

INVITE?sip：mary@home.net?SIP/2.0

If request purpose user ID is a group identification, can add domain name prefix " sip:group-list1@conference.home.net " equally as service identification.

In this method example, the professional satellite information outside the request purpose user ID still can be carried by logic fix information section, shown in the example in method example one, the method example two.

Because described logic fix information section is logical definition,, also can comprise following mode so the mode of carrying of professional satellite information is not limited to the mode described in above-mentioned three examples.Only summarize for simplicity, particular content can be analogized according to above-mentioned three examples and drawn.

1, logic fix information section is not distinguished the professional satellite information (request purpose user ID, user service data, dialogue identifier etc.) of different attribute, service-param parameter as the aforementioned, at this moment, can be by network based different service identification, and, distinguish the professional satellite information of different attribute to the parsing of professional satellite information.

2, can be by attribute (the request purpose user ID of professional satellite information, user service data, dialogue identifier etc.) distinguish the logic fix information section of carrying the different business satellite information, as ask purpose user ID input header field and user service data to import header field, request purpose user ID incoming event bag and user service data incoming event bag, request purpose user ID input body and user service data input body etc., also can be in logic fix information section, to distinguish professional satellite information such as the different attribute that carries request purpose user ID and user service data by different parameters, even all right user service data of further distinguishing different attribute, as user ID, card number, password, Permission Levels, time etc.

3, can distinguish the logic fix information section of carrying the different business satellite information by the different mode of operation of business, as keyboard input information, menu input information etc., keyboard input information is meant that generally the user passes through the service requesting information that the push-button dialing mode is imported, service requesting information is made up of the keypad character of user's input, concerning keyboard input information, service identification is generally imported by the user, keyboard input information is equivalent to the keypad facility information unit (Keypad facility information element) of keypad protocol (Keypadprotocol) in the Digital Subscriber signalling No.1 (Digital Subscriber Signalling No.1), it allows the user to call (invoke) business by the access code (being the service feature sign indicating number) that network provides, the menu input information generally is meant the service requesting information of user by the menu mode input, comprise the menu item sign that the user selects, the menu input information is equivalent to the facilities information unit (Facility information element) of functional agreement (Functionalprotocol) in the Digital Subscriber signalling No.1, wherein the menu item sign promptly can be represented service identification, as " CONF (meeting) ", also can represent service identification and operator scheme thereof, as " beginCONF (beginning meeting) ", " endCONF (closing session) ", in the menu input information, service identification (also can further comprise professional operator scheme) generally is to be selected according to interface display or function key that terminal provides by the user, can further include the parameter value of the corresponding input in user's choice menus item sign back in the menu input information; Also can be by the different mode of operation of different parameters differentiated service in logic fix information section.

4, can distinguish the logic fix information section of carrying the different business satellite information by the different operation purpose of business, as calling service operation, user service data operation etc.; Also can be by the different operation purpose of different parameters differentiated service in logic fix information section.To the calling and can further distinguish of business, as activation, deexcitation etc. by different operator schemes.

5, can in logic fix information section, further distinguish the satellite information of different service types, promptly define the satellite information parameter of different service types, in embodiment, " reverse-charging-consulting " and " user ", " rights ", " language " are exactly the satellite information that adheres to freephone, convention business separately.Need to prove, though distinguished different business here, distinguish in logic fix information section, is not the different different logic fix information sections of service definition.Type of service can be represented by service identification, also can represent by service identification with to the operator scheme (as activation, deexcitation etc.) of business, can see that this mode requires to carry service identification in the logic fix information section.

This wherein, as previously mentioned, owing to defined some business and satellite information thereof in the current SIP standard by different header fields, incident bag etc., as describing " caller ID display restriction " business by the Privacy header field, describing " Messages-Waiting indication " business etc. by message-summary incident bag, consider from compatibility, the information input header field of the present invention's definition or information incoming event bag or information input body can also be quoted these existing definition, and example is as follows: Info-Input:Privacy=id.In fact, these business that define in the current standard and the use of satellite information thereof generally all are that the user adopts aforesaid menu mode operation input, therefore, as preferred embodiment, can quote these existing definition in aforesaid menu input information.

This wherein, the mode that also has a kind of satellite information of more special differentiation different business, when professional satellite information is when being imported by the network requirement user, can also represent dissimilar professional satellite informations by network settings, set parameter and do not need publicity (promptly not being standard definition), only effective in current business is used, network sends a request message to the user, carry the parameter of this generic request user input parameter value in the message, except that the characterising parameter title, the data type of all right defined parameters, after setting up successfully writing to each other of user and network, network sends the SIP INFO to the user, and the prompting user imports card number, password, example is as follows:

INFO?sip：[5555::eee:fff:aaa:bbb]：8805?SIP/2.0

Content-Type：application/info-input

require-input＝card，type＝xs：string[16]，tag＝abc123

require-input＝password，type＝xs：string[6]，tag＝xyz789

In the example, " sip:[5555::eee:fff:aaa:bbb]: 8805 " be user's contact address (setting up) because write to each other, " require-input " carries parameter name and the data type that requires the user to import, having described data type in the example respectively is that 16 character strings " card " (card number), data type are 6 character strings " password " (password), and what data type adopted is XML Schema standard.That is to say that the service requesting information of carrying in this request message has only been described title and data type, do not have concrete service requesting information content.

The user receives this request message, and " card ", " password " parameter of display requirement user input on the interface after user's input parameter value, send the SIP INFO to network, wherein carry concrete service requesting information content, and example is as follows:

INFO?sip：as.example.com?SIP/2.0

Content-Type：application/info-input

user-input＝card，value＝1234567890888888，tag＝abc123

user-input＝password，value＝123456，tag＝xyz789

In the example, " sip:as.example.com " carries out this professional network element domain name addresses, and " user-input " is the response of " require-input ", carries the parameter value of user's input.It is the value of which parameter that network can mate the parameter value of confirming input by the parameter name that requires the user to import, as " card ", " password "; Can also for requiring the tag value of the correspondence that parameter that the user imports generates, each mate by network, as the tag value " abc123 " of card number parameter, and the tag value " xyz789 " of cryptographic parameter.

At last, need to prove, the different modes of above-mentioned differentiated service satellite information, can be used, such as the satellite information that can in the logic fix information section of expression menu input information, distinguish different service types, the parameter of keyboard input information and the parameter of carrying different attribute can be in logic fix information section, carried for another example simultaneously, even the satellite information of different attribute can be in carrying the parameter of keyboard input information, distinguished again.

In addition, when logic fix information section is carried professional satellite information, can also carry operator scheme simultaneously to this business satellite information, as increase, deletion, modification etc., by carrying different operator schemes, can represent to increase or deletion user service data or request purpose user ID or dialogue identifier.When logic fix information section is carried service identification, can also carry operator scheme simultaneously to this service identification, expression to the business of service identification sign activate, operations such as deexcitation, checking, hang-up (time-out), recovery, i.e. calling to business.Operator scheme can be carried by keyboard input information or menu input information, can defaultly not carry yet, convention business as the aforementioned, the operator scheme of request purpose user ID or dialogue identifier is thought " adding " meeting by default, aforesaid for another example messaging service, the operator scheme of request purpose user ID is thought " reception " message by default, and also the operator scheme that can regard this generic operation pattern as a kind of implicit expression is carried.

If described logic fix information section is an information input body, then its occupation mode is as follows:

In the above-described embodiment, always by the information input parameter, or information input header field, or information incoming event bag, or a certain mode in the information input body unifies to carry the service requesting information outside the Request-URI, in fact at the information input parameter, or information input header field, or information incoming event bag is when carrying service identification (this moment, Request-URI carried request purpose user ID), the particular content of other satellite information of this business also can be imported body by information and carry, indicate whether in the freephone as the aforementioned and the satellite information of called negotiation that example is as follows:

INVITE?sip：mary@home.net?SIP/2.0

Info-Input：800

Content-Type：application/info-input

reverse-charging-consulting＝true

That is to say that information input body can use separately as a kind of logic fix information section, also can be used with one of other three kinds of modes (information input parameter, information input header field or information incoming event bag).Further, the indication (not having concrete service requesting information content) that one of other three kinds of modes can only provide a kind of service requesting information to transmit, promptly indicating currently has certain business to be requested to use, the particular content of this service requesting information outside the Request-URI is then carried by information input body, comprise service identification, such as being used of information incoming event bag and information input body, example is as follows:

INVITE?sip：mary@home.net?SIP/2.0

Subscription：info-input

Content-Type：application/info-input

service-id＝800

Here, information incoming event bag only represents that business is requested to use, being requested professional concrete business information content " 800 " (service identification) is then carried by information input body, certainly also this and information can be imported the incident bag called after " service request incident bag " that body is used this moment, this is the difference of name just, and example slightly.

In addition, the parametric description form (text formatting) of information input body in above-mentioned example, can also adopt the XML form to describe different service requesting information elements (element), as service identification element, request purpose user ID element etc.

Further specify below, in the present invention the range of application of service requesting information:

The inventive method is applicable to all sip messages, as: SIP INVITE invitation message, SIPSUBSCRIBE subscribe message, SIP NOTIFY notification message, SIP REFER Reference News, SIP INFO informational message, SIP MESSAGE instant message, SIP PUBLISH gives out information and various sip response sign indicating number message etc.

Wherein, in current standard Session Initiation Protocol, have only SIP SUBSCRIBE, SIPNOTIFY, SIPPUBLISH message can carry the incident bag, it is expansion of the present invention that other message is carried the incident bag.

Among the present invention, the difference of use information incoming event bag and other three kinds of modes is: use the incident bag to carry being used of service requesting information or aforesaid incident bag and information input body, expression has been initiated a subscribe request to this service request, initiate the service requester of service request and acceptance and the professional effector that manages business between need to create and safeguard the subscription example (subscription) of this incident bag correspondence.

In addition, in the foregoing description, when initiating communication request by the user, service identification etc. import, in fact, also may be that network produces, receive the Client-initiated communication request message as network, according to user's service profile, in message, add service profile corresponding service sign, as the freephone sign etc.; Perhaps network is initiatively initiated communication request message, carries service identification etc. in message, and the present invention is equally applicable to this kind situation.

The multiple mode of carrying in Session Initiation Protocol of service requesting information has been described in the front, general, as preferred embodiment, can use information import header field or information input body, distinguish keyboard input information and menu input information by different parameters therein, keyboard input information is used for carrying the information (" * 40*26500000 " as the aforementioned) of user service data operation, the information (the service feature sign indicating number of " 800 " and so on as the aforementioned) of calling service, is example with information input body as logic fix information section:

Content-Type：application/info-input

<keypad-input>*40*26500000</keypad-input>

Or

Content-Type：application/info-input

<keypad-input>800</keypad-input>

Wherein, " keypad-input " promptly represents the keyboard input information parameter.

Can be divided into two class parameters in the menu input information again: a class parameter is carried different service types information, as previously mentioned, promptly can be by service identification differentiated service type (being aforesaid menu item sign expression service identification), and distinguish the calling of business with operator scheme, as:

Content-Type：application/info-input

<menu-input>

<service-id>REV_CHARGING</service-id>

<op-mode>active</op-mode>

</menu-input>

Wherein, " menu-input " promptly represents menu input information parameter, " servie-id " is service identification parameter (promptly identifying different types of service), " REV_CHARGING " is the sign of freephone, " op-mode " is operation mode parameter, and " active " (activation) is a kind of value of operator scheme;

Perhaps, also can come differentiated service type (being aforesaid menu item sign expression service identification and professional operator scheme) by service identification and operator scheme thereof, as:

Content-Type：application/info-input

<menu-input>

<service-op>activeREV_CHARGING</servie-op>

</menu-input>

Wherein, " service-op " expression service identification and operation mode parameter thereof, " activeREV_CHARGING " expression is " an activation freephone " to the operator scheme of freephone, and the service-op parameter can be regarded the combination of above-mentioned servie-type and two parameters of op-mode as.

Another kind of parameter is carried the satellite information (as request purpose user ID, dialogue identifier etc.) of different attribute in the menu input information, and with the operation of operator scheme differentiation to these satellite informations, as:

Content-Type：application/info-input

<menu-input>

<user-identity>28780000</user-identity>

<op-mode>add</op-mode>

</menu-input>

Wherein, " user-identity " expression request purpose user identification parameters, " add " (increase) is a kind of value of operator scheme.

Can see, can also comprise the professional satellite information parameter (as user identification parameters, dialogue identifier parameter etc.) of different type of service parameter (service identification parameter, service identification and operation mode parameter thereof), operation mode parameter, different attribute in the menu input information.

Different parameters form in the menu input information can be preset in the user terminal; Also can be by network equipment such as application server, push to user terminal, user operation menu and import corresponding parameter value after, by the sip message transmission, general, except the information input body that can adopt above-mentioned XML to describe transmits in the sip message body, can also adopt sip message to carry SOAP (Simple Object AccessProtocol, Simple Object Access Protocol) body, or XCAP (XML Configuration Access Protocol, extending mark language configuration access agreement) mode of body, SOAP or XCAP are that the standardization of XML is used, and concrete introduction can be referring to relevant criterion.Adopt SOAP or XCAP format description for information input body, perhaps define the MIME medium type that a general SOAP or XCAP use, as " application/xcap+xml "; Perhaps define a MIME medium type that indicates SOAP or the concrete application scenarios of XCAP,, show that XCAP uses in business information of the present invention as " application/xcap-srvinfo+xml "; Perhaps still keep the MIME medium type example of aforesaid information input body, obtain when the application form of SOAP or XCAP is resolved the sip message body by sip user agent.

Service requesting information generally all is to be initiated by user terminal, the embodiment of the invention also provides a kind of user terminal apparatus of initiating service requesting information, referring to shown in Figure 2, this device comprises service requesting information boundary element, service requesting information receiving element and the service requesting information transmitting element that links to each other successively, wherein:

But described service requesting information boundary element is used for providing to the user operation interface of incoming traffic solicited message, this interface is by forming to the display interface of user's display message with for the inputting interface of user's input information, described display interface can be one of following three kinds of modes at least: be stored in advance in the described user terminal apparatus, network equipment pushes in the described user terminal apparatus, the user sets in advance in described user terminal apparatus, wherein, the interface that the user sets in advance in described user terminal apparatus can be finished by the interface operation that described other dual mode provides by the user, as the user as described in the telephone directory book that sets in advance in the user terminal apparatus.

Described service requesting information receiving element is used to receive the service requesting information that the user imports on described service requesting information boundary element, user's input mode can be one of following dual mode at least: keying input information, the information of selecting to be built in the described service requesting information boundary element are imported telephone number that shows in the service requesting information boundary element as described in the latter is chosen in as the user or service identification etc.

Described service requesting information transmitting element is used for the service requesting information that described service requesting information receiving element receives is configured to the fix information section of sip message, and sends this sip message.Described make can be one of following three kinds of modes at least: the request purpose user ID that described service requesting information receiving element is received is configured to the Request-URI message segment, and service identification and other professional satellite information that may exist that described service requesting information receiving element is received are configured to logic fix information section; The service identification that described service requesting information receiving element is received is configured to the Request-URI message segment, and the professional satellite information that described service requesting information receiving element is received is configured to logic fix information section; Request purpose user ID and service identification that described service requesting information receiving element is received are configured to the Request-URI message segment.Described logic fix information section comprises keyboard input information section and/or menu input information section, can be uri-parameters parameter or header field, incident bag or message body.

● details are as follows at service announcements information and service interworking information.

Business information is except solicited message, announcement information can also be arranged, after business is requested, have the corresponding business announcement information and notify the operating position of current business to service requester, professional effector can pass through SIP NOTIFY, SIP PUBLISH, SIP INFO, SIP MESSAGE message, reach various sip response sign indicating number message etc. this moment, carried service announcements information and sent to service requester.

General, can directly in this information output body, professional current operating position be described by text mode, such as, to aforesaid convention business in use, if user alice has withdrawed from meeting, network element as professional effector will send a service announcements information to service requester, notify this situation by text " Alice has quitted the conference (Alice has withdrawed from meeting) " to service requester user A in information output body.

The recipient of service announcements information is except service requester, can also be professional participant or related person, operating position to its notice current business, convention business in use as the aforementioned, user alice has withdrawed from meeting, except sending a service response information, can also send a service announcements information as professional effector's network element to another meeting participant mary to service requester.

Content of announcement in the service announcements information is generally generated by network, also can be imported by the user.

The mode of professional current operating position is described in the service announcements information, except above-mentioned text mode, it can also be the advice method of other medium type, as voice (signal tone or verbal announcement etc.) etc., convention business in use as the aforementioned, user alice has withdrawed from meeting, except sending the service announcements information of a text mode, can also send a service announcements information of carrying the verbal announcement of " Alice withdraws from meeting " as professional effector's network element.

Concerning the service announcements information content of voice mode, can be the chained address of a voice medium, also can be the indication of sound-type, can also be the formation of voice is described (as signal tone frequency, break-make ratio etc.) etc.

To same professional operating position, service announcements information can only be carried a kind of advice method, also can carry the advice method of different media types.General because the difference of ability of user terminal, if any terminal do not have the text display ability, the advice method that therefore carries different media types simultaneously can have more versatility.

In addition, business information is except above-mentioned service requesting information and service announcements information, can also be service interworking information, the recipient of service interworking information uses the described business of this information processing, such as, once communication can cause a plurality of different business, and these business are handled by service control network element different in the network, and when existing compatibility or priority etc. to conflict between these business, then need between these service control network element, transmit the professional operating position of different business, to coordinate calling of these business.

Though service interworking information and service announcements information all are the current operating positions of business transferring, but what the latter represented only is a kind of announcement information, when describing such as the employing text mode, the recipient of service announcements information is the display notification content, and does not go to resolve concrete professional implication wherein; And to the former, owing to calling that harmony messages will be used to manage business, the recipient of service interworking information must resolving information content, the kind of the business of therefrom extracting and the current operating position of business.Therefore, in service interworking message, must be able to define the kind and the professional current state of concrete business, such as, can adopt aforesaid service identification to represent professional kind, professional current state can be defined as some kinds of " waiting to be activated ", " activating ", " wait is cancelled ", " temporarily cancelling ", " cancelling ", " deexcitation ", " time-outs " etc., and form is the character string of text mode.Certainly, also can represent professional kind by concrete service identification, extract identical service feature but some are had in the business of similar characteristics, concrete business is put into different categories, represent professional kind, what promptly Ye Wu kind was represented is the business that a class has the identical services feature.

Convention business in use as the aforementioned, user John call-conference service requester user A, send a SIP INVITE to user A, this wherein may cause certain business, and should business and convention business conflict mutually and can not be called simultaneously, therefore user A is after receiving this SIP INVITE, can be in the sip response sign indicating number message of returning, carry a service interworking information, transmit the current operating position of convention business to this professional service control network element, the harmony messages content comprises: the professional current state of convention business sign and " activating ".

Similarly, service interworking information goes for aforesaid all sip messages.

In the present invention, can be by another information input medium type of definition in the sip message body, by be arranged in the sip message fixed position, import body for this shared information of different business and carry service announcements information and service interworking information; Perhaps in sip message, be defined as different business shared another information input header field, carry service announcements information and service interworking information by this header field.

This above-mentioned information input body and this information input header field are logical definition, can be that the new extended message body of definition is used or header field in Session Initiation Protocol, also can be that existing message body is used or the expansion of header field is used in the Session Initiation Protocol, can carry service announcements information and service interworking information respectively by different information input bodies or information input header field, also can in same information input body or information input header field, carry service announcements information and service interworking information.

In some cases, service announcements information and service interworking information can be same message segment in Session Initiation Protocol, show that it promptly can be used as service announcements, also can be used as service interworking, such as following situation, when SIP packet domain and other protocol domain such as circuit domain intercommunication, service announcements information will be carried between different agreements, obviously, network need be resolved service announcements information and be handled, be converted into opposite end procotol loaded information, also to generate service announcements information according to opposite end procotol loaded information, at this moment, also service interworking information during the service announcements information of same, for instance, the message segment assignment of an expression " calling transfer " " call transferred ", can be sent to user terminal (service announcements information receiver) in the time of in the SIP packet domain shows, and with the circuit domain intercommunication time, interconnection network element need be resolved this message segment assignment, be converted into the message segment assignment of the expression " calling transfer " that ISUP (Integrated Services Digital Network UserPart) agreement carries, promptly " call transferred " promptly is that service announcements information also is service interworking information, and this interconnection network element promptly is that the service announcements information receiver also is the service interworking information receiver.Perhaps, also has a kind of situation, user terminal needs to show on terminal interface according to the business information of receiving, carry out corresponding service processing according to the business information of receiving simultaneously, this moment, this business information promptly was that service announcements information also is service interworking information, for instance, user terminal is received a new incoming call calling in conversation, carry " Call Waiting " message segment in the calling message, user terminal is resolved this message segment, and on terminal interface, show " new incoming call calling is arranged " in view of the above, handle calling of call waiting simultaneously in view of the above.

In addition, carry information input body or the information input header field and aforementioned information input body or the information input also shared message body of header field or the header field application of carrying service requesting information of above-mentioned service announcements information and service interworking information, distinguishing by different parameters, can certainly be that different message body or header fields used.Wherein, further, concerning service requesting information and service interworking information, can carry the service identification parameter, and professional operator scheme and professional current state have similarity, therefore can also adopt identical parameter to represent the service requesting information and the service interworking information of carrying by the menu input information in same information input body or information input header field, example be as follows:

Content-Type：application/info-input

<service-info>

<service-id>REV_CHARGING</service-id>

<service-status>require-active</service-status></service-info>

Wherein, owing to will use identical parameter to represent service requesting information and service interworking information, therefore can not use the parameter " menu-input " of aforesaid expression menu input information, and make " service-info " parameter into, represent the business information relevant with type of service, " service-status " is professional current state parameter, can be used for representing operator scheme simultaneously to business, " require-active " (requesting activation) is a professional current state parameter value, be equivalent to aforesaid operation mode parameter value " active ", the professional current state of also promptly representing aforesaid " waiting to be activated ", certainly, also can still represent professional operator scheme and professional current state respectively.

In addition, it is mutual between sip user agent that the sip message that carries business information has been described in front of the present invention, to realize the transmission of business information, in fact, according to the SIP standard, sip user agent is a kind of of SIP entity (entity), obviously according to standard definition, the sip message that carries business information with the fix information section can also be at other SIP entity, as at Redirect Server (Redirect Server), acting server (Proxy Server), transmit between the Registrar (Registrar), and between sip user agent and these SIP entities, transmit.

At last; also need to prove; the information input parameter of the present invention's definition; or information input header field; or information incoming event bag; or information input body; comprise the miscellaneous service sign; the title of professional satellite information; and descriptor format; only be to make the characteristic example; if also have other this class definition; although title is different with form; as long as but comprised the characteristic (service identification that Session Initiation Protocol of the present invention carries business information; professional satellite information; and service announcements information; service interworking information is used fix information section transmission in the message), all will be in claimed scope of the present invention and so on.

Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
