Definitions
- the present invention discloses a multiple access system in a communications network.
- MAPIM Access PDN connectivity and IP flow mobility
- technologies such as UMTS/GPRS, LTE, WLAN, WiMax, DOCSYS and fixed broadband access.
- a terminal would use both e.g. WCDMA access and WLAN access to access the same destination Packet Data Network, PDN, using one and the same IP-session.
- the system would then support operator defined policies for service-based routing of the UE IP-flows via different access systems.
- a Packet Data Network Gateway which is arranged to receive and forward packet data of at least a first and a second service flow in both an uplink and a downlink direction, with a first access network of a first kind being used for the first service flow and a second access network of a second kind being used for the second service flow.
- the PDN-GW of the invention is arranged to transmit to a PCRF, a Policy and Charging Rules Function, information regarding which kinds of access networks that the PDN-GW can handle, and to receive, in reply from the PCRF, rules for which of said access networks that should be used for said service flows.
- the PDN-GW of the invention is also arranged to use said rules to bind a service flow to an access network in the downlink direction and to perform access network binding verification in the uplink direction.
- the transmission to and reception from the PCRF, as well as the use of said rules is carried out in a Policy and Charging Enforcement Function, a PCEF, in the PDN-GW.
- a PCEF Policy and Charging Enforcement Function
- the PDN-GW is arranged to receive and use said rules as packet filters.
- said filters utilize protocol header info in the packets.
- said filters utilize application information in the packets.
- the access networks include two or more of the following: UMTS/GPRS, LTE, WLAN, WiMax, DOCSYS and fixed broadband access.
- Fig 1 shows an overview of a system in which the invention is applied
- Figs 2 and 3 show flow charts of a method of the invention.
- Fig 1 shows an overview of a system 100 for which the invention is intended.
- the system 100 can accommodate one or more User Equipment, UE, one of which is shown as 140 in fig 1.
- UE User Equipment
- the UE 140 can use a number of service flows simultaneously, and can also operate on two or more access networks simultaneously, so that if, as shown in fig 1 , there are two simultaneous service flows, Flow 1 , Flow 2, and two Access Networks, 125, 130, each service flow can be assigned to "its own" Access Network.
- the system 100 is a packet data system, and comprises a so called PDN- GW, Packet Data Network Gateway, which interfaces towards, for example, a Packet Data Network PDN 115 and Terminal Equipment TE 120.
- the PDN GW 105 has a so called Gx interface towards a Policy and Charging Rules Function, a PCRF 110.
- a principle behind the present invention is to let the PCRF 110 inform the PDN-GW 105 of which service flows that should be associated with which Access Networks, both in the uplink, UL, and downlink, DL, directions.
- a schematic flow chart 200 of how this is done on the control plane is shown in fig 2:
- the UE requests access to one or more access networks, such as, for example, WLAN and UMTS/GPRS.
- the PDN-GW authorizes those access networks to the UE.
- the PDN-GW informs the PCRF 110 of the available access networks for the UE 140.
- the PCRF allocates service flows to/from the UE 140 to the available access networks for the UE 140.
- the PCRF 225 sends the allocations and corresponding filters to the PDN-GW 105, suitably to the so called Policy and Charing Enforcement Function, the PCEF in the PDN- GW.
- the PDN-GW 105 can then inspect packets in both the UL and the DLK and enforce the access network policies sent by the PCRF.
- Step 305 shows an incoming data packet, UL or DL, to the PD-GW, or the PCEF in the PDN-GW.
- the PDN-GW or its PCEF matches the packet to the service flow filters.
- the PDN-GW forwards the packet to the associated access network, and in the UL, the PDN-GW attempts to verify that the packet was sent on the correct access network.
- the PDN-GW drops the packet, which is also done in the UL if the verification fails.
- Operations on dynamic PCC-rules over the Gx-interface include installation, modifications and removal of rules on a per IP-session basis. This invention would affect the installation, modification and possibly also the removal procedures. For those procedures, the Charging-Rule-Definition AVP would be provided within the Charging-Rule-lnstall AVP or in a Charging-Rule-
- the Charging-Rule-Definition AVP contains all the necessary information for the PCEF to identify whether or not an incoming packet belongs to the Service Data Flow of a dynamic PCC Rule or not.
- This invention proposes to either complement the Charging-Rule-Definition AVP with the access specific information or to include this information in the Charging-Rule-lnstall AVP and in the Charging-Rule-Remove AVP. Both these cases should be covered for completeness.
- the Access-Network-Information (this is just a generic name and not a parameter) could be e.g. the IP-CAN-Type AVP defined in TS 29.212.
- This AVP is currently used in Rel ⁇ Gx on message level to indicate the type of Connectivity Access Network in which the user is connected. In the example above the same AVP would be used to indicate which specific IP-CAN the PCC rule or PCC rule operation applies to.
- the Access-Network-Information could also be an identifier to a specific access network e.g. PLMN-id. This would be useful in case access to multiple homogenous networks is allowed e.g. access to multiple WLANs at the same time.
- Access-Network-Information is not necessarily restricted to a single network but may define a list of valid access networks or types of access networks (possible with a preference assigned). For this case the PCRF would not be required to provide updated policy decisions to the PCEF in case the UE/NW would decide to re-direct the IP-flow to one of the allowed accesses.
- the Access-Network-Information would be used by the PCEF at classification of incoming packets. Downlink packets classified to a service data flow associated with a certain PCC rule will be forwarded to the selected access network in accordance to the access specific information of the PCC rule. Classified packets in the uplink from the different accesses will be verified against this information (out of profile packets may be dropped).
