Embodiment
Session Initiation Protocol is a main solution that realizes speech business on the internet; Whole SIP network can be end-to-end or network is centralized.When the SIP network is concentrated as network, when controlling, can calculate correlative charges with a server as the third party.The present invention is exactly in the SIP network, brings the terminal use with relevant toll data in the sip message body.
The essence of this patent is based on reservation-notice (SUBSCRIBE-NOTIFY) message system, wish that the network terminal initiation SUBSCRIBE (reservation) that obtains relevant toll data asks application note expense to be notified, server is informed user-dependent toll data by notifying (NOTIFY) message.Simultaneously, what need as the terminal use is to send advice of charge in end of calling, the present invention proposes with the BYE request or the BYE request responding is carried relevant charge information to feed back to the terminal use.
The method of the invention relates to the operation of following Session Initiation Protocol:
INVITE (invitation): a kind of request mode in the Session Initiation Protocol is used to make a call;
A kind of response mode in the 180 Ring:SIP agreements is represented called shake bell;
A kind of response mode in the 200 OK:SIP agreements is represented this request success;
ACK (affirmation): a kind of request mode of Session Initiation Protocol is used for INVITE is asked the checking of resulting response message;
SUBSCRIBE (reservation): a kind of request mode in the Session Initiation Protocol, be used for requiring the incident of being correlated with, normal and NOTIFY is used;
NOTIFY (notice): a kind of request mode in the Session Initiation Protocol is used for notifying dependent event;
BYE (release): a kind of request mode in the Session Initiation Protocol is used for call release.
In order to make Session Initiation Protocol have the ability that the network-oriented terminal sends advice of charge, the present invention expands Session Initiation Protocol, and the concrete content that expands is:
I.1) increase a new type (having increased a new entity type in other words) in content type (Content-Type) header field (also can the be entity type) the inside of Session Initiation Protocol:
Application/charging (application/billing), the message body that is used to identify Session Initiation Protocol are and the relevant information of chargeing.When the network terminal or server are analyzed from the Content-Type header field when obtaining this type, the network terminal or server know that the content of message body the inside is and the relevant information of chargeing, and the content of message body the inside resolved, thereby draw relevant and the relevant information of chargeing.
I.2) in the Event of Session Initiation Protocol (incident) header field, increase shape such as following expansion:
Event：aoc；type＝intermediate；notify-duration＝60；
Wherein aoc represents Advice of Charge (notics of charge), and type parameter can be got to call out and carry out (intermediate) or end of calling (Final); If be the intermediate type, need to give the time interval of putting up a notice; Otherwise, need not give the time interval of putting up a notice.
When above-mentioned incident band was got in the SUBSCRIBE request, server was analyzed the type of Event, and promptly this is an incident of subscribing notics of charge as can be known, require to send notics of charge when calling is carried out, and the time interval that sends was 60 seconds.

For example: Advice-State:Final, expression done state.
II.2) note is taken type (Charge-Type) header field, is used to indicate concrete charging way, i.e. type of Ji Feiing.Take about note, several different methods is arranged, the present invention has defined wherein four kinds: caller note expense (Normal), do not remember expense (Free), called note is taken (Reverse), and calling and called are shared (Share, for sharing, provide a percentage, the ratio that the expression caller should be shared.It mainly is to consider to increase a kind of flexi mode that calling and called are shared).This header field is an essential option.
For example: Charge-Type:Normal, the expression usual manner, the caller note is taken.
II.3) type of service (Service-Type) header field, be used to indicate charging based on type of service.If calling relates to some other business and this charging is relevant with business, then need to provide relevant type of service.This header field has defined the type of business development, is option.
For example: Service-Type:cfu, represent that this type of service is Call Forwarding.
II.4) note is taken unit (Charge-Units) header field, is used to indicate the time span as the cost increases standard, and the base of note expense is second.Usually, if not coin free service, then must provide note expense unit.This header field is an essential option.
For example: Charge-Units=12, the time interval of expression Charging Detail Record unit is 12 seconds.
II.5) currency unit (Currency-Units) header field is used to indicate the expenses standard of charging; Just each note is taken the expense that unit should be paid; Its unit is circle (specifically depending on the currency type that is adopted).If not free, this header field should occur.This header field is an option.
For example: Currency-Units=1.4, the expense of representing the Charging Detail Record unit needs of each benchmark is 1.4 circles.
II.6) call duration (Duration) header field is used to indicate and calls out the current time that has continued.This header field has provided the duration of calling out (unit is second).The reference information that this information is taken as note must occur, and is essential option.
For example: Duration:140 represents that current call duration is 140 seconds.
II.7) total cost of this calling (Total-Fee) header field is used to indicate the total cost of this calling, is option.
Based on above-mentioned expansion to Session Initiation Protocol, advice of charge of the present invention adopts following method to realize:
(a) by NOTIFY (notice) message;
(b) by BYE (release) message (when server was sent out BYE, toll data was carried in server the inside in the message body of BYE request);
(c) by 200 responses (when terminal was sent out BYE, server carried toll data in 200 message bodies that respond to the BYE request) to BYE (release) message.
