Definitions

  • the invention concerns methods and devices for controlling data transmission policies in at least one telecommunication network.
  • QoS Quality of Service
  • Resources are needed to provision QoS.
  • admission control and resource planning are needed.
  • Two criteria are relevant in admission control : one about the eligibility of the request and the other about the resource availability for the request.
  • An eligibility check will decide which traffic types/flows are entitled to which services. That is, services should be regulated. It is apparent that the related management decisions and configurations should be conducted consistently and automatically. It is therefore desirable to deploy policy- based QoS management in the UMTS networks.
  • policy based management networking activity is conducted according to a set of policy rules that specify the objectives to be achieved and the actions to be taken. It can lead to a system where the decisions and configurations are conducted consistently and automatically.
  • SBLP service based local policy
  • IMS IP Multimedia Subsystem
  • the Go interface allows service-based local policy and QoS inter-working information to be pushed to or requested by the Policy Enforcement Point in the GGSN from a Policy Control Function (PCF) .
  • PCF Policy Control Function
  • This information is used by the GGSN in support of, e.g., control of DiffServ interworking, control of the service-based policy "gating" function in GGSN and other functions as defined in stage 2 specifications [3GPP TS 23.207: "End-to-end QoS Concept and Architecture", V5.2.0, Jan. 2002.] .
  • the Go interface uses IP flow based policies.
  • the Go interface shall conform to the IETF Common Open Policy Service (COPS) protocol defined in [IETF RFC 2748] .
  • COPS Common Open Policy Service
  • the COPS protocol supports a client/server interface between the Policy Enforcement Point in the GGSN and the PCF.
  • the Go interface shall conform to the IETF COPS-
  • the 3GPP SBLP and Go solutions are based on the IETF COPS model and protocol [IETF RFC2748, RFC2753] .
  • the two main architectural devices for policy control are the PEP (Policy Enforcement Point) and the PDP (Policy Decision Point) .
  • the PEP represents a component that runs on a policy aware node. It is the point at which policy decisions are actually enforced. Policy decisions are made primarily at the PDP.
  • the communication between the PDP and the PEP is conducted using the COPS protocol.
  • the abstract terms PDP and PEP correspond to Policy Server and Policy Client Device in a concrete network environment .
  • PDP corresponds to the PCF (as part of a P-CSCF) and.
  • PEP corresponds to GGSN 1 in the GPRS network.
  • the IMS subsystem is access- independent . And each access system will normally have its own policy server (PDP) . In order to allow coordination of the PDPs, they should be assigned the same client type. Again, this is not consistent with the COPS model .
  • PDP policy server
  • the invention proposes to modify and extend the current COPS model by using the following innovative function and method:
  • PRP Policy Regulation Point
  • PRP is to coordinate and regulate the functionality of the
  • PDPs themselves.
  • a PDP registers with the PRP to get its basic configuration and task assignment.
  • the interaction between the PRP and the PDPs are active and dynamic. Which means that the PRP will regulate the functionality of the PDPs dynamically and the PRP will also react to the dynamic states of the PDPs, which in turn may cause the PRP to adjust the behavior of other PDPs.
  • the state consistency among PDPs is maintained.
  • the coordination of the PRP can be static. It can also be dynamic to achieve the effect of dynamic adjustment, dynamic load balancing, dynamic activation and deactivation of policy rules, etc. (This is in contrast to the coordination by a static entity like a passive database . )
  • the suggested enhancement allows a more flexible policy control architecture. (This will serve as an input to further standardization in 3GPP Release 6. It can also serve as an input to the related IETF working groups . )
  • a function entity called Policy Regulation Point can be introduced in the policy architecture based on the COPS model as an active device to coordinate and regulate policy servers (PDPs) ; policy servers (PDPs) are configured by the PRP about the basic division of responsibility at the time of initialisation and active interaction is conducted between the PRP and the PDPs in response to changing network situations.
  • PRP Policy Regulation Point
  • Figure 1 shows the usage of a policy regulation device PRP ⁇ in an IP Multimedia Subsystem IMS with two access networks .
  • Figure 1 illustrates an example of the invention, where a dynamic adjustment of traffic regulation at macro-level is achieved. In the example, it is assumed that it is desired, to favor the traffic from, the GPRS access area over the traf ic from the WLAN access area, which will both pass through an

Abstract

L'invention vise à améliorer le contrôle de la politique du réseau. A cet effet, l'invention concerne un procédé de contrôle des politiques de transmission des données dans au moins un réseau de télécommunication (11, 15). Selon ce procédé, les dispositifs de décisions stratégiques (=point de décision statégique (PDP) 18, 19) transmettent respectivement à au moins un dispositif de transmission (12, 13, 14, 16, 17) les instructions qui définissent les politiques de transmission des données (12, 13, 14, 16, 17) d'au moins un réseau de télécommunication (11, 15). Un dispositif de régulation des politiques (PRP 20) transmet (1, 2) aux dispositifs de décision stratégique (PDP 18, 19) des instructions qui définissent respectivement une nouvelle politique d'au moins un dispositif de transmission (13, GGSN3). Un dispositif de décision stratégique (18) transmet (3) à au moins un dispositif de transmission (13= GGSN3) des instructions qui définissent respectivement la nouvelle politique du/des dispositif(s) de transmission (13) et sont basées sur les instructions que le dispositif de décision stratégique (PDP 18) a reçues du dispositif de régulation de politique (PRP 20). Le ou les dispositif(s) de transmission (13) modifie(nt) sa/leur politique de transmission de données conformément aux instructions qu'il a (13) reçues du dispositif de régulation de politique (PRP 20).
