Description
Technical field
The present invention relates to wireless communication field, more particularly, relate to strategy and billing control method under a kind of user roaming state.
Background technology
In third generation partner program (3GPP), discuss based on the charging (FBC, Flow Based Charging) of Internet protocol (IP) stream for realization.For a Packet data service, the user is using the data volume that this business consumed to be called business data flow (Service DataFlow), and business data flow is the set that a plurality of IP streams are formed.And in a PDP Context (context), can carry a plurality of different business, and therefore be far smaller than charging based on PDP Context based on the granularity of the charging of IP stream, thus can for operator or service supplier provides the more charging means of horn of plenty.
Divide for the functional entity of realizing FBC according to present 3GPP, TPF carries IP traffic, when IP carrying is set up or during bearing modification (QoS is consulted again), TPF can send the charging regulation request to CRF by the Gx interface, can carry user's information relevant in the request (as Mobile Subscriber International ISDN number MSISDN with terminal, IMSI International Mobile Subscriber Identity IMSI), the relevant information of bearer properties (as QoS information etc.) and network is (as Mobile Network Code MNC, Mobile Country Code MCC MCC), the information of carrying in the charging regulation request message of CRF according to TPF, select a suitable charging regulation to return, comprise billing mechanism (adopting online charging or offline charging) in the charging regulation to TPF, charge type (also being based on the charging of flow based on duration), charging key (parameter relevant) with rate, business datum flow filter and this charging regulation priority.Wherein, be used to indicate TPF need filter out in the business datum filter and be applied to this charging regulation for which IP stream.Can comprise IP5 tuple information such as (source/purpose IP address, source/destination interface number, agreement ID) in the filter, as to be used for CRF indication TPF need be 10.0.0.1 for source address, destination address is 10.0.0.2, source/destination slogan is 20, agreement is that the IP traffic of TCP filters, and uses charging regulation to charge to the IP traffic that filters out.
CRF can provide Event trigger (trigger event) to TPF, in order to notice TPF when some incidents takes place, the charging regulation that need please look for novelty to CRF, the charging regulation that requires TPF when some bearing modification incident takes place, just please look for novelty as CRF to CRF.The TPF that can cause that defines in the standard asks the event trigger of charging regulation to comprise SGSN change (SGSN variation) again at present, QoS change (QoS variation), RAT type change (variation of RAT type) and TFT change (TFT variation).In addition, CRF is except the input information according to TPF decides the charging regulation of choosing, and CRF can also accept AF or the input information of OCS decides the charging regulation of choosing.Such as, what AF notice CRF active user used is any business, thus CRF chooses the charging regulation corresponding with this business.
OCS is made up of SCP (Service Control Point service control point) and two functional entitys of CCF (Credit Control Function credit control function) as Online Charging System, and the user credit when wherein CCF is to online charging manages.When the user used business, CCF carried out authentication to the credit in this user's the credit pool, and issued the operable credit of user to TPF.In addition, OCS can require TPF to report to OCS when some discrimination weight incidents (Re-authorisation triggers) take place, and this moment, OCS carried out discrimination weight according to the incident that TPF reports to the user, and may calculate again user's credit.When chargeing as the subregion, operator uses different charging rates for the user of different regions, OCS determines a rate according to user's present located position, and calculate user's credit according to this rate, when the user moves to another position, as the SGSN change events has taken place, TPF needs this event notice to OCS, OCS determines new rate according to the new residing position of user, and recomputates the new credit of user.And for example, when OCS uses professional QoS to determine rate according to the user, when the user has carried out the QoS modification, as the bearing modification incident has taken place, TPF needs this event notice to OCS.OCS determines new rate according to new QoS, and recomputates the new credit of user.These that define in the standard may cause that the incident of discrimination weight comprises that credit expired (credit authorisation lifetime expiry), user idle state overtime (idle timeout), the charging regulation of permission change (charging rule is changed) at present, in addition, some GPRS incidents such as SGSN change (SGSN change), QoS changes (QoS changes), RAT type change (RAT typechange) etc.
Corresponding to GPRS network, TPF is GGSN, and AF is a Service Gateway among the PDN, or service server, and CRF is newly-increased logic entity.The function of TPF is that charging regulation is carried out point, and CRF is the control point of charging regulation.For providing conversation-based policy control scheme (SBLP) among the Rel6 and based on the billing scheme (FBC) of SDF (Service Data Flow), these two schemes have certain function plyability (for example, FBC can provide policy control functions to a certain degree).So just cause a problem, a same function (for example gating function) uses SBLP and FBC to realize.Simultaneously, the information that reference point interface transmitted that two kinds of mechanism is used also have bigger repetition, and therefore, this complexity that repeats to increase system has reduced the efficient of system.From the another one aspect, this come mechanism that issues of strategy and charge information branch also can be increased the time delay of system operation (for example carrying foundation).
In order to improve the efficient of system, simplify the operation, reduce time delay, need to consider the policy control and the control of chargeing are merged, this fusion simultaneously also is possible, the mechanism after the fusion is exactly PCC.
In the PCC of new Rel7, these two function schemes will fully merge in the new function structure.This real time interactive operation system that optimization better is provided in GGSN (and GW of other Access Network) that is beneficial to that is associated with.The same with FBC, the basic object of operating in PCC is SDF.Similarly, all operations are all passed through PCC rule (being charging rule) and are expressed and be sent among the execution functional entity in the network in FBC in PCC.CAMEL-Subscription-Information, new binding mechanism and the combination of PCC rule make PCC can be suitable for more generally applied environment (have AF do not have AF, GPRS and non-GPRS carrying or the like).PCC provides a more unitized operating platform for the enforcement of how new application.
In order to guarantee the competitiveness of 3GPP system in the following time, the work of an access technology evolution is just carried out at the 3GPP organization internal.Particularly, in the 3GPP system, use group technology to need further to strengthen in order to strengthen the 3GPP system handles ability of the IP data service of growth fast.Most important several sections comprises in this class technology evolution: reduce time delay, Gao Su user data rate more, the reduction of the power system capacity of enhancing and coverage and operator's integral body cost.The core net of wireless evolution network mainly comprises MME, UPE, three logic function modules of Inter AS Anchor, MME wherein is the mobile management module, be responsible for the mobile management of chain of command, comprise the management of user's context and mobile status, distributing user temporary identity sign, safety function etc., it is corresponding to the control plane part of current UMTS internal system SGSN; UPE is a user entity, is responsible for initiating paging for downlink data under the idle condition, and IP bearing parameter and the interior routing iinformation of network etc. are preserved in management, and it is for the datum plane part of current UMTS internal system SGSN and GGSN; Inter AS Anchor then serves as the user's face anchor point between different access systems.The function of each interface among the figure and whether exist is not still finally determined.MME, UPE among the figure, how three functional modules of Inter AS Anchor are combined in the entity also is undetermined.
This shows, in evolution network framework, also need to adopt PCC to carry out policy control and billing operation, still, determine as yet at present for the position of PCEF, might be on the MME/UPE entity, also might be on Inter-AS Anchor.No matter how the position of PCEF changes, and present PCC framework is constant basically.
But, do not have clear and definite PCEF in the present standard and be arranged in which network entity, therefore work as the user and be under the roaming situation, and can't realize the strategy of UE and the control of chargeing.
