Abstract
The invention provides a method for real-time auditing dynamic flow between service-based policy decision function (SPDF) and border gateway function (BGF) in a resource and admission control subsystem (RACS). The method comprises the S202 and the SPDF send auditing request command to request the BGF to report flow auditing data; and the S204 and the BGF report the flow auditing data to the SPDF according to the received auditing request command. By the technical proposal in the invention, user can perform dynamic flow searching, analysis, statistic, decision making and other treatments through network administration, local decision-making, and other means, so as to provide more convenient means and more timely flow data for network provider.
Description
Technical field
The present invention relates to the fixed telecommunication field, relate in particular to resource and admission and control subsystem (Resource and Admission Control Subsystem, RACS) interior strategy decisive function (Service-base Policy Decision Function based on business, SPDF) and the middle Border Gateway Function of transmission network (Border Gateway Function carries out the implementation method of network auditing system between BGF).
Background technology
Resource and admission and control are next generation network (Next Generation Network, NGN) middle completely new concepts of introducing.It is between service control layer and carrying transport layer, by carrying out resource and admission control, detail to upper-layer service shielding transmission network, supporting business control is separated with transmitting function, and the resource operating position of perception transmission network is controlled by admittance and resource downwards, guarantee to use transport network resources with holding water, thereby guarantee that (Quality of Service QoS), and prevents that bandwidth and professional stolen phenomenon from taking place to professional service quality.
Resource and admission control is at first at (the EuropeanTelecommunications Standards Institute of ETSI, ETSI) be engaged among the TISPAN of standardization body (Telecommunication and Internet convergedservices and protocols for advanced networking) of NGN research clearly proposing in, its correlation function is called Resource and Admission Control Sub-system (RACS).
Figure 1 illustrates the framework of the RACS among the TISPAN R1.
As can be seen from the figure, this RACS is made up of two entities:
One is based on professional policy control functions SPDF, and it provides unified interface to upper layer application, and the concrete access style of shielding bottom-layer network topological sum provides the policy control based on business.SPDF selects local policy according to the request of application function (AF), and will ask to be set as the IPQoS parameter, sends to Access-Resource and Admission Control Function and Border Gateway Function (BGF), to ask corresponding resource.
Another is accommodating access resource controlled function (Access-Resource and Admission Control Function), and it is arranged in Access Network, has the function that control of admitting and network strategy converge.From SPDF reception request, realize admitting control based on the strategy of being preserved then, acceptance or refusal are to transmitting the request of resource.Access-Resource and Admission Control Function obtains to adhere to information and user QoS inventory information from Network Attachment Subsystem (NASS) by the e4 reference point, thereby can determine available network resources according to network configuration information, simultaneously when the processing resource allocation request with reference to user QoS inventory information.
Border Gateway Function (BGF) is the entity in the transport layer, and it is one and wraps packet gateway that it can also can (realize interconnected Border Gateway Function) between core net and Access Network (realization Core Border Gateway Function) between two core net.BGF finishes network address translation (nat), gate, QoS mark, bandwidth constraints, use measurement and source synchronous function by the Ia reference point under the control of SPDF.After existing Ia reference point (according to ETSI ES 283 018) can be implemented in service conversation and finishes pass through agreement H.248 deduct (SUBTRACT) response command (issuing the subtract rpl of SPDF from BGF) band network packet (network package, NT) the Statistics descriptor in returns the statistical information of current sessions flow, wherein, this statistical information comprises the transmission byte number, receives byte number, duration.These information check that for the user charge on traffic in this session traffic and later stage all is very significant.
Yet, present case is that these statistical informations can only report SPDF by BGF when conversation end, and the user can not dynamically check the flow of current on-line session, thereby can not make corresponding statistics, analysis and decision to the flow of on-line session, and this is a kind of very inflexible situation.
Summary of the invention
The present invention seeks to overcome the limitation of the network auditing system that prior art exists, in the hope of realizing dynamic network auditing system.
According to an aspect of the present invention, a kind of flux auditing method is provided, be used for dynamic flow audit real-time between the BGF of interior SPDF of RACS and transmission network, this method comprises that following processing: SPDF sends the audit request command to BGF at any time as required, and BGF reports the network auditing system data with request; And BGF reports network auditing system information according to the audit request command that receives to SPDF.
Trigger SPDF by external system (as webmaster) and send the audit request command to BGF.
Wherein, BGF reports the network auditing system information processing to be specially: BGF gathers the network auditing system data of current sessions and the network auditing system data is formed the NT bag after receiving the audit request command; BGF is to SPDF loopback audit response message, and reports the network auditing system data; And the audit response message loopback that SPDF will receive is given external system or is carried out this locality decision-making.
According to a further aspect in the invention, a kind of flux auditing method is provided, be used for dynamic flow audit regularly between the BGF of SPDF and transmission network in the RACS, method comprises that following processing: SPDF sends increase/modification request command to BGF, reports the network auditing system data to ask BGF; And BGF reports the network auditing system data according to the increase/modification request command that receives to SPDF.
After the Application Function initiation session, SPDF sends increase/modification request command to BGF.
In addition, when carrying out resource authorization and revise mandate, SPDF sends increase/modification request command to BGF.
In increase/modification request command, have timed events and duration.
BGF reports the network auditing system information processing to be specially: BGF gathers the network auditing system data of session in the predetermined amount of time and the network auditing system data is formed the NT bag after receiving increase/modification request command; BGF is to SPDF loopback increase/modification response message, and timing reports flow to relate to data; And increase/modification response message and network auditing system data that SPDF will receive send to external system or carry out this locality decision-making.
By the present invention, the user can carry out processing such as dynamic flow inquiry, analysis, statistics, decision-making by means such as webmaster, local decision-makings, for network operation provides means and data on flows more easily more timely.
Other features and advantages of the present invention will be set forth in the following description, and, partly from specification, become apparent, perhaps understand by implementing the present invention.Purpose of the present invention and other advantages can realize and obtain by specifically noted structure in the specification of being write, claims and accompanying drawing.
