Detailed description of the invention

For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, below in conjunction with this Accompanying drawing in bright embodiment, is clearly and completely described the technical scheme in the embodiment of the present invention, Obviously, described embodiment is a part of embodiment of the present invention rather than whole embodiments.Based on Embodiment in the present invention, those of ordinary skill in the art are obtained under not making creative work premise The every other embodiment obtained, broadly falls into the scope of protection of the invention.

Figure 1A is the one of the HNB that is based on of various embodiments of the present invention and fixed broadband network interworking architecture Schematic diagram.Figure 1B is the HNB that is based on of various embodiments of the present invention and fixed broadband network interworking architecture Another kind of schematic diagram.In the framework shown in Figure 1A and Figure 1B, HNB passes through BBF access network and SeGW Connection establishment IPsec tunnel, UE under HNB utilize the IPsec tunnel set up access SeGW and then Access 3GPP network.PCRF in 3GPP network please by the QoS of CS territory business or PS territory business Ask and be sent to BPCF by the interface between itself and BPCF, BPCF QoS request is permitted Control operation.Reach BBF access network by above-mentioned flow process to assist alternately with 3GPP network interworking, QoS The purpose of business.Wherein, BBF access network includes routing gateway or local gateway (Routing Gateway/Residential Gateway；Referred to as: the RG) wideband network gateway being connected with RG (Broadband Network Gateway；Referred to as: BPCF BNG) and with BNG being connected.

In framework shown in Figure 1A, SGSN is connected to S-GW by S4 interface, is thus connected to HNB 3G PS territory business to carry out QoS information eventually through PGW with PCRF mutual.At frame shown in Figure 1B In structure, SGSN is connected to GGSN by gn interface, is thus connected to the 3G PS territory business of HNB QoS information is carried out mutual eventually through GGSN with PCRF.

In framework shown in Figure 1A and Figure 1B, HNB GW needs by the interface between itself and PCRF Need by connecing between itself and PCRF for CS territory service selection one PCRF, PGW or GGSN Mouth is one PCRF of PS territory service selection.At present, the interface between HNB GW and PCRF is referred to as S15 interface, the interface between PGW or GGSN and PCRF is referred to as Gx interface.

Wherein, the data gateway in 3GPP network (such as HNB GW, PGW or GGSN) passes through Diameter route agent (Diameter Routing Agent；Referred to as: DRA) this logic function unit Select PCRF.Concrete, in HNB power up, HNB GW is CS territory industry by DRA Business selects a PCRF, and sets up S15 session with this PCRF.When the UE being connected to HNB passes through When BBF network and 3GPP network carry out CS territory business, such as CS territory calling, CS territory call modification Deng, HNB GW sends the qos parameter in CS territory to PCRF, PCRF by S15 session and will connect The qos parameter received is sent to BPCF and carries out admissions control.In this process, DRA can be this UE Set up with UE be designated index DRA binding, this DRA binding include UE mark (NAI), Pass between the PCRF address that the IPv4 address of UE and/or IPv6 prefix and this IP-CAN session select Connection.By this DRA binding can make from same UE with this IP-CAN session as effective object All request message are all routed in DRA binding the PCRF selected for this IP-CAN session.

When, in all UE being connected to HNB, certain UE initiates to activate PDP Context request for the first time When message initiates PS territory business the most for the first time, PGW or GGSN is PS territory service selection by DRA One PCRF, and set up IP-CAN session with this PCRF, PCRF please by IP-CAN session establishment Ask the qos parameter in message to be sent to BPCF and carry out admissions control.

In framework shown in Figure 1A or Figure 1B, two different network elements of HNB GW with PGW/GGSN Different time points be same HNB select PCRF, therefore cannot ensure HNB GW and PGW/GGSN is that same HNB selects identical PCRF.

When PCRF Yu BPCF sets up S9^*After session, BBF network can be by S9^*Session and IPsec tunnel (being equal to HNB here) associates one by one.When two PCRF are respectively by different S9^*Session When sending admission request to BPCF, BPCF is the QoS request from two different IPsec tunnels Carry out scheduling of resource respectively, but in fact the two QoS request is from same HNB, thus cause money Source distribution is inaccurate.Such as: assume that the PCRF that DRA is CS territory service selection has been from IPsec The CS territory business application in tunnel ample resources, and the PCRF that DRA is PS territory service selection is not Knowing this situation, now DRA is that the PCRF of PS territory service selection also can be for from same HNB PS territory business application resource, owing to BPCF will be considered that this is the QoS from another IPsec tunnel Asking and have granted this request, thus causing BBF network is that this HNB is (in other words for same IPsec Tunnel) distribute too much resource, thus affect the resource to other HNB (i.e. other IPsec tunnels) Distribution.

For the problems referred to above, one embodiment of the invention provides one to be same under the HNB-BBF network architecture The method that the CS territory business of one HNB and PS territory business select identical PCRF in PLMN, bag Include: HNB GW is according to the mark of the HNB received in activation PDP Context request message, from advance The HNB binding relationship table first generated obtains the mark of a PCRF corresponding with HNB, and by HNB Mark and the mark of a PCRF be sent to data gateway；Data gateway selects from multiple PCRF Oneth PCRF, and the admission control operations of PS territory business is carried out by PCRF and BPCF.

Wherein, a PCRF be HNB GW be the PCRF that the CS territory service selection of HNB goes out, with Time be also data gateway be the PCRF that the PS territory service selection of HNB goes out.In framework shown in Figure 1A, Described data gateway refers to PGW, and in framework shown in Figure 1B, described data gateway refers to GGSN.

The PCRF system of selection that the present embodiment provides, HNB GW is in the CS territory service selection for HNB During PCRF, the mark including HNB of generation and a PCRF's corresponding with this HNB The HNB binding relationship table of mark, and be CS territory service selection the oneth PCRF of HNB, for HNB PS territory service selection PCRF time, HNB GW, from the HNB binding relationship table previously generated, obtains Take the mark of a PCRF, and the mark of the mark of a PCRF with HNB be sent to data gateway, Make data gateway when for PS territory service selection PCRF of HNB, same select a PCRF, make Obtaining network elements different from data gateway the two for HNB GW can be same HNB at different time points CS territory business and PS territory service selection one PCRF, solve because of select different PCRF cause to The inaccurate problem of resource of HNB distribution and other various problems.

The flow chart of the PCRF system of selection that Fig. 3 provides for one embodiment of the invention.As it is shown on figure 3, The method of the present embodiment includes:

Step 201, HNB GW are that HNB selects a DRA, and please to a DRA transmission session Ask.

Wherein, conversation request includes the mark of HNB.Interface quilt between HNB GW and DRA When being referred to as S15 interface, this conversation request can be S15 conversation request, but be not limited to this.

In actual application, when HNB powers on, HNB obtains HNB's from fixed broadband network Local ip address.HNB uses the local ip address of HNB to set up the IPsec tunnel with SeGW. HNB is registered to HNB GW, and sends the local ip address of HNB to HNB GW.HNB GW Use DNS mechanism to select a DRA (the i.e. the oneth DRA) from PLMN, send S15 meeting simultaneously Words set up the request message DRA to selection, and carry the local ip address of S15 session id and HNB.

In the present embodiment, using the local ip address of HNB as the mark of HNB, but it is not limited to this. Such as: HNB can also obtain the MAC Address of HNB, and using the MAC Address of HNB as HNB Mark.The most such as: there is the mark of uniqueness in advance for HNB definition.

Step 202, a DRA are that HNB selects a PCRF according to conversation request, and by first The mark of PCRF is sent to HNB GW.

In actual applications, a DRA can be that this S15 session distributes a PCRF (i.e. first And can be by mark (the IP address of the such as the oneth PCRF or the MAC Address of a PCRF PCRF), Deng) it is sent to HNB GW.The mark of the oneth PCRF is sent to the mistake of HNB GW by the oneth DRA Journey includes: a DRA forwards S15 session establishment request message with proxy mode to a PCRF, and The S15 session establishment completion message that a PCRF sends can be received.A DRA will carry first afterwards The S15 session establishment completion message of the mark of PCRF is transmitted to HNB GW.Now, S15 session is built Stand successfully.

Further, in above process, a DRA will also create with the local ip address of HNB as rope The DRA binding relationship (the i.e. the oneth DRA binding relationship) drawn, a DRA binding relationship includes: The mark (local ip address of such as HNB) of HNB, S15 session identification (ID), a PCRF Mark.Further, a DRA binding relationship also includes: (this is temporarily IP-CAN session id Null value).

Step 203, HNB GW are by the mark binding of the mark of HNB with a PCRF, and storage is arrived In HNB binding relationship table.

After HNB GW receives the mark of the PCRF that a DRA sends, by the mark of HNB Bind with the mark of a PCRF, and store in HNB binding relationship table, for data gateway (PGW/GGSN) lay the first stone to PS territory service selection PCRF of this HNB.

Through above-mentioned steps, HNB GW one PCRF (i.e. that has been the CS territory service selection of HNB One PCRF).Afterwards, a PCRF will set up session with BPCF, and a PCRF passes through session Send admission request and carry out scheduling of resource to the QoS request that BPCF, BPCF are this HNB.Its In, the interface between PCRF and BPCF is S9^*During interface, PCRF Yu BPCF it Between session be S9^*Session, but it is not limited to this.Session between oneth PCRF and BPCF can be along with The change of interface between the two and change.Between various embodiments of the present invention are not with PCRF and BPCF Interface be S9^*As a example by interface.

Step 204, HNB GW are according to the HNB's received in activation PDP Context request message Mark, obtains the mark of a PCRF corresponding with HNB from the HNB binding relationship table previously generated Know, and the mark of HNB and the mark of a PCRF are sent to data gateway.

When, in all UE connecting HNB, having certain UE for the first time when HNB initiates PS territory business, Will to HNB GW send carry HNB mark (such as: the local ip address of HNB) swash PDP Context of living asks message.After HNB GW receives activation PDP Context request message, from Activate the mark obtaining HNB in PDP Context request message.

Then, HNB GW finds and from activating PDP from the HNB binding relationship table previously generated The mark of the PCRF of the mark binding of the HNB hereafter obtained in request message.In the present embodiment, HNB GW gets the mark of a PCRF from HNB binding relationship table.
