Description
Technical field
The present invention relates to the system of telecommunication service quality control, refer to a kind of Access Network conversation control system and method especially.
Background technology
ETSI (ETSI), International Standards Organization such as (ITU-T) of standardization department of international telecommunication union telecommunication think that all Next Generation Telecommunication Networks is structured in IP or packet switching is online.Along with the continuous development of technology, on IP, provide the technological trend of unification of three nets to manifest day by day.But the design original intention of IP network only is the interconnection problems that solves the equipment that is positioned at different places, has great opening.Also be just to be able to the significant progress that obtained in short Internet technology during the decade because of it is open, substantially spread to family, and become people's daily life and work in indispensable part.Simultaneously, also, can't guarantee the professional service quality and the safety of customer access network because it is open and only provide interconnection capability.
The purpose of service quality is exactly to be various communication services, comprises data, image, speech, multimedia or the like, and providing reliably end to end, service quality guarantees.
Concrete Qos problem mainly contains:
Time delay: be meant that the IP packets of information is from sending to the time interval of reception;
Shake: refer on the paths variation of different grouping (packets of information) propagation delay time in the data flow;
Packet loss: refer to that when network congestion certain business is permissible maximum packet loss in network, etc.
These problems affect are to the telecommunication service reliability of service, for example: the reliability of connection, the time that connects, retention time etc.Solution service quality (Qos) problem is the important topic in the network development.
Telecommunications network PSTN has passed through the continuous evolution of decades because of being closed system, just develop into multiple services networks such as collection intelligent network, DDN, but it safe and reliable service quality that possesses has obtained public widely knowledge.But itself technical problem can't be to the same broadband service in the Internet.
At present Next Generation Telecommunication Networks faces the problem that needs to solve and provides reliable service quality as PSTN, and last " one kilometer " of the development of puzzlement broadband also is to have service quality problem equally, because there is bigger convergence ratio in Access Network, realize that reliable service quality just need undergo technological transformation to this " one kilometer ", just transforms the Access Network of metropolitan area network.
At present ETSI TISPAN working group adopt as shown in Figure 1 network configuration the later network in IP edge (IP Edge) is carried out QoS control, wherein, the carrying control subsystem is by Access-Resource and Admission Control Function (Access-ResourceAllocation Control Function accommodating access resource function), SPDF (Service PolicyDecision Function is based on the decision function of business game), RCEF (Resource ControlEnforce Function Resource Control Enforcement Function), CBGF (Core Border Gateway Function core edge gateway function) constitutes, and Access-Resource and Admission Control Function is responsible for controlling RCEF according to business demand and the strategy of user profile such as NASS and SPDF; RCEF is responsible for controlling the resource allocation and the policy distribution of transport layer; SPDF obtains professional resource allocation demand and strategy from Gq interface, and these are distributed to Access-Resource and Admission Control Function and CBGF; It is mutual that business is passed through Gq ' or Gq interface and carrying control subsystem, and IP edge device (IP Edge) passes through Ra or other interactive interfacings with Access Network (AN) equipment; Be responsible for setting up that user terminal is connected with the AN network is home gateway (CNG:Custom Network Gateway), this CNG might be that a part of Access Network also may be a part of user terminal.Its service call process as shown in Figure 2, step is as follows: (1) subscriber equipment (CPE) sends register requirement to service server; (2) CPE sends out service call super to service server; (3) CPE and the service server session resource requirement of holding consultation; (4) service server is to the resource reservation application of carrying control subsystem initiation session; (5) the carrying control subsystem is sent Session Resources to IP Edge and is reserved signaling, and sends the admittance response by IP Edge to the carrying control subsystem; (6) the carrying control subsystem is sent the application of resource reservation success to service server; (7) business allows to continue.
Though the Qos managerial ability that this network configuration of ETSI TISPAN working group is strengthened to a certain extent, it is defectiveness still, and reason is that it has only stayed a logic interfacing to Access Network, is not described in detail.As Access Networks such as DSL the traffic aggregation of a large number of users being got up to deliver to IP Edge carries out two layers of termination and provides professional, and the control system (Access-Resource and Admission Control Function and SPDF) by TISPAN can solve the service quality from IP Edge to IP Edge, but can't solve from the user to the service quality the IP Edge.Because lack the Ra interface in the existing system of TISPAN,, also can't guarantee the service quality of user uplink to IP Edge so can't obtain the topology information of Access Network.Widely used ADSL access technology can partly solve up service quality problem by the differential service mode owing to adopt the little and big discharge model of downlink bandwidth of upstream bandwidth.But it is, above-mentioned just particularly outstanding to the service quality problem between the IP Edge the user along with emerging access technology such as GPON, SH.DSL etc. adopt the little discharge model of upstream and downstream bandwidth size differences.
