Description of drawings
Fig. 1 shows the first embodiment of the present invention, and
Fig. 2 shows the second embodiment of the present invention.
Embodiment
Fig. 1 shows first embodiment that can be considered to basic example, and this embodiment comprises PPS 3, and uses PPS 3 but not SCE (service creation environment) in core net.As shown in Figure 1, portable terminal or user terminal (MT/UE) 1 can be communicated by letter with one or more CSCFs (CSCF) 4.Subscriber database stores elemental user information such as HSS 2, described elemental user information comprises that assignment gives the recognition data of one or more PPS servers 3 of described user or MT/UE 1 (portable terminal/subscriber equipment), for example title or address, preferably IP address.
Call out or other type connects in order to start, MT/UE 1 may be by sending " invitation " message 1.) the conventional SIP " invitation " that carries out for CSCF (CCF) 4 operates.Described " invitation " operation is the part of SIP (session initiation protocol), and described SIP is the signaling protocol based on IP communication of being used for by ietf definition.CSCF 4 is by carrying out HSS inquiry 2.) from HSS (home subscriber server) 2 user profile of packing into.Described HSS 2 return messages 3.), promptly comprise user profile data such as the PPS information of PPS address.At next procedure 4.) in, CSCF 4 addressing PPS 3, and request starts the user's 1 of session prepaid information.PPS 3 returns the message 5. of the described user's of indication actual door limit value (still spendable real surplus prepayment volume)).Then, if described threshold value is enough to start session, then step 6. can be started) such as the session of calling out.When described calling as 7.) shown in end the time, CSCF 4 calculates the session expenses, and with it from step 5.) in deduct the threshold value that received.The residue threshold value can be returned (message 8.) to PPS 3, as current effective gate limit value.PPS 3 corresponding minimizing user accounts, and the employed amount of money is transferred to the account of operator.
Fig. 2 shows another embodiment, and wherein PPS uses with SCE (service creation environment).Access Network separates with core net, and uses external business.
Explain the step of carrying out according to Fig. 2 hereinafter with reference to the appended number of steps of information flow shown in Figure 2.
1.) GPRS Access Network 11 (for example the SGSN of GPRS network, Serving GPRS Support Node) triggers the first service creation environment unit (SCE1) 12.Step 1.) the triggering message that is sent in comprises the identity of the recognition data such as the IP address, CIE (charging cell) unit and the Access Network of PPS 14.
It should be noted, when GPRS terminal UE (subscriber equipment) 10 in execution in step 1.) made the GPRS additional request before or when upgrading, then user profile (comprise the title of PPS 14 and/or such as the address of IP address) is downloaded to SGSN from HSS 13.So PPS 14 identity are known in this stage.Whole world charging _ the ID relevant with calling is included in the identity of CIE (charging cell) unit and Access Network.
2.) SCE1 12 asks prepaid information from PPS 14, and CIE is sent to PPS 14.Whole world charging _ ID is linked to temporary transient " virtual " account of user in the PPS 14.For the purpose of chargeing, the Access Network identity is stored in the PPS.
3.) PPS reduces the appropriate portion of user account, and the result of calculation threshold value, and this threshold value is back to SCE1 12.Described share can be counted or calculate according to the parameter that comprises in the CIE unit (for example basic GPRS access fee), thereby for example makes described threshold value enough be used for 5 minutes connection.As selection, described PPS 14 may be simply be back to SCE1 12 with the actual value of the current storage of account of advances.
4.) SCE1 12 is back to GPRS 11 with the threshold value that is received.If threshold value is used up, then should or remove described connection by GPRS 11 another threshold values of request.Should be noted in the discussion above that SCE1 12 may provide value-added service on the GPRS level.If like this, then must be by the primary charging request being sent or increases to PPS or asking the charging (all can use CIE under two kinds of situations) of combination expense to come described value-added service is chargeed respectively.Should also be noted that SCE1 12 (and second additional service creation environment SCE2 15) also may only be used to interior business.If do not use described business, then may make described connection directly from GPRS network (for example SGSN) 11 to PPS 14.
5.) UE 10 will (comprise the whole world CSCF 16 that charges _ ID) be sent to such as the message of " invitation " message.
6.) CSCF 16 carries out HSS 13 inquiries.
7.) HSS 13 is back to CSCF 16 with user profile data (comprising PPS information).
8.) CSCF 16 triggers SCE2 15, and whole world charging _ ID is sent to SCE 2.
9.) SCE2 15 is from PPS 14 request prepaid information.CIE is passed to PPS 14 (at SCE2 or CPS, finishing basic charging in the call processing server).Whole world charging _ ID links to temporary transient " virtual " account of user, and core network identity is stored for billing purpose.
10.) PPS reduces user account with appropriate portion, and calculates or provide threshold value.Described share may be calculated according to the parameter that comprises in the CIE unit (for example basic core network expense), thereby for example makes described threshold value enough be used for 5 minutes connection.As selection, described PPS 14 may be simply be back to SCE1 12 with the actual value of the current storage of account of advances.
11.) SCE2 15 is back to CSCF 16 with described value.In CSCF 16, reduce described threshold value according to billing parameter.Charge if carry out in SCE2 15, the CIE unit that then will have the residue threshold value returns.
Should be noted in the discussion above that with for SCE1 and step 4.) explanation similar, SCE2 15 may provide the value-added service on the core net level.If like this, then must be by the primary charging request being added to PPS 14 or coming described value-added service is chargeed respectively for combination expense charging (all can use CIE under two kinds of situations).Should also be noted that SCE2 (and SCE1) also may only be used to interior business.If do not use described business, then may make described connection directly from GPRS network (for example SGSN) 11 to PPS 14.
After this, indicated as solid horizontal line, described calling/connection starting.
CSCF 16 is responsible in the core net level and the threshold value in the SGSN in the GPRS network level reduces.More if desired Stored Value then must must be asked from PPS 14 according to step 8-11 in GPRS network according to step 1-4 from PPS 14 requests in core net.
12.) external business 17 is requested.Should be noted in the discussion above that described external business also may be PSTN network, ISP (Internet service provider) or other any business that is positioned at outside the core net.Described request will comprise whole world charging _ ID.
13.) external business 17 returns and have billing parameter the CIE unit of the identification of (professional expense etc.) and server.
14.) CSCF 16 is from the new threshold value of SCE2 requested service, and the CIE that will have an above-mentioned parameter is included in the described request.
15.) SCE2 15 is from the new threshold value of PPS 14 request.CIE with above-mentioned parameter is included in the described request.The identity of PPS 14 storage services.May in SCE2 15 or PPS 14, carry out about whether allowing the user to use the inspection of institute's identification services.
16.) new threshold value is back to SCE2 15 from PPS 14.
17.) SCE2 15 is back to CSCF 16 with described new threshold value.
When described calling/when connection will be terminated, described calling/connection was eliminated (" end of calling ").
18a., 18b.) will remain threshold value and be back to SCE1 12 and SCE2 15.
19a., 19b.) will remain threshold value and be back to PPS 14.PPS 14 increases user account with described value.PPS 14 will use the expense of Access Network, core net and external business to be sent to corresponding account.
Therefore, PPS 3,14 comprises or each PPS of access, each user and institute that may each user account allow the database of business (address/name/identity).For described business, PPS preferably can transfer accounts money after CSCF 4,16 receives corresponding charge information from user account.
SCE 12 and/or 15 is suitable for comprising basic tariff information.It preferably can also provide the different business that influences billing parameter.
By means of providing of PPS, online prepaid billing and AoC (advice of charge) may be introduced terminal.The user equally can be from PPS On line inspection account.Described feature makes network operation by network operators handle, and makes it free.Charging case and nonessential is paid in the back, also no longer needs.
The PPS server also needs not to be operator's node.For example, if some or all telephone operator preferences prepayment and thereby needn't play the effect of bank, then the user may reach a kind of direct charging protocol of the part as user profile with operator.So PPS may preferably be suitable for being responsible for chargeing, checking employed business and handling account balance.Described server for example can be a bank server, and it distributes money between access carrier, core operator and different business provider.In complete IP network, can there be a large amount of different business providers.More advantageously, the user needn't pay some different little accounts, and only need to pay on an account by PPS control.
Although below described the present invention with reference to specific embodiment, the present invention has been contained equally and has been represented above-mentioned characteristics combination, omission, modification and other alternative embodiment.
