Embodiment
For making the object of the invention, technical scheme and advantage clearer, below lift embodiment and, the present invention is done further explain with reference to accompanying drawing.
In the present invention, RG is called local gateway, and BNG/BRAS is called non-3 GPP access network and closes.
Fig. 3 inserts the flow chart of the method for evolved packet system for the present invention; As shown in Figure 3; The method that this present invention inserts evolved packet system is that RG is under the route pattern; WLAN moves the scene of UE through S2a interface access mobile core net (EPC) as non 3GPP network trusty, and wherein the S2a interface adopts PMIP interface or GTP interface.Wherein, fixed network and mobile network (EPS) are respectively UE and distribute an IP address, and perhaps only (EPS is UE distributing IP address by the mobile network.In UE, preserve two or an IP address.Optional employing DHCP agreement between RG and the BNG/BRAS.The method that the present invention inserts evolved packet system specifically may further comprise the steps:
Step S301 carries out peer-peer protocol (PPP, Point-to-PointProtocol) negotiation and verification process between RG and the BNG/BRAS; In the ppp negotiation process; BNG/BRAS is that RG distributes local ip address, i.e. ustomer premises access equipment (CPE, Customer Premises Equipment) IP.
Step S302 carries out the DHCP negotiations process between UE and the RG, in the DHCP negotiations process, RG is that UE distributes an IP address, is generally private network IP, is called IP2 among the present invention.
More than two steps all be the operation of just having supported in the existing network, therefore need not network is strengthened (upgrading etc.).In the present invention, if UE not from the demand of WLAN by-pass shunt, this step S302 can omit, and does not carry out.If UE only is implemented to the access of EPS through fixed network such as WLAN etc., then need not execution in step S302, in the time of promptly need not passing through the fixed network access external network, needn't execution in step S302.
Step S303 carries out PPP LCP and consults between UE and the RG, and selected authentication mode.Need adopt the EAP authentication because the 3GPP regulation inserts the non-3 GPP access network of EPC, authentication mode selected in this LCP consults is the EAP authentication.
Step S304, RG, BNG/BRAS are as the agency (proxy) of EAP authentication, and also as the agency of EAP authentication, UE inserts through fixed network with mobile network (user among the EPS) identity BBF AAA, and is accomplished to the Certificate Authority of 3GPP HSS/AAA, and authentication mode is EAP.
Step S305, HSS/AAA is to the response message of BPCF transmission EAP authentication success, and BPCF transmits this authentication success message to BNG/BRAS.
Step S306, BNG/BRAS receive the triggering of authentication success message, initiate strategy session and set up.Wherein strategy session comprises the fixed network strategy session between BNG/BRAS and the BPCF, the S9* session between BPCF and the PCRF.This step can be carried out or omitted in different scene.Specifically need be according to connection also is based on the GTP connection and determine whether to omit this step based on PMIP between BNG/BRAS and the P-GW, if connect based on PMIP between BNG/BRAS and the P-GW, then this step is essential step; If connect based on GTP between BNG/BRAS and the P-GW, this step can be omitted.
Step S307, BNG/BRAS receive the triggering of authentication success message, to P-GW request tunnel binding.
If the S2a interface between BNG/BRAS and the P-GW is based on the interface of PMIP, then BNG/BRAS sends PBU message to P-GW; If the S2a interface between BNG/BRAS and the P-GW is based on the interface of GTP, then BNG/BRAS sends to P-GW and creates conversation request message.
Comprise in the wherein above-mentioned tunnel binding request message: APN (APN; Access PointName); International mobile subscriber identity information such as (IMSI, International Mobile Subscriber Identity) is to ask IP address assignment to P-GW.
Step S308, P-GW receive PBU message or create after the conversation request message, carry out the foundation of IP-CAN session between meeting and the PCRF.
Step S309, P-GW carry out the renewal of P-GW sign to HSS.
Step S310, the establishment conversational response message that P-GW replys PBA or GTP to BNG/BRAS, carrying P-GW in this message is the UE IP address allocated, is called IP1.
Step S311, BNG/BRAS receive PBA/ and create after the conversational response message, from message, obtain after the IP1, send to RG through EAP authentication success message.
RG sends authentication success message to UE, wherein can carry address ip 1 in this authentication success message, also can not carry address ip 1.Here, do not carry IP1, then can store this IP1 information, and can distribute the IP address of private network, be referred to herein as IP3, and the mapping relations between IP3 and the IP1 are set to UE at RG if RG sends in the authentication success message to UE.Certainly, aforesaid operations also can carry out in BNG/BRAS, and promptly BNG/BRAS is the IP3 that UE distributes private network, and mapping (Mapping) relation between IP3 and the IP1 is set, and this IP3 information is sent to UE through RG.Its implementation and RG storing IP 1 and IP3 is set and IP1 between mapping relations basic identical.It will be appreciated by those skilled in the art that above-mentioned only is to replenish as what technical scheme of the present invention is realized carry out, is not to be used to limit the present invention.
Step S312 is to step S313, and RG obtains the IP1 address.And the IP1 address is sent to UE through the PPP ipcp negotiation, perhaps, the IP3 address corresponding with IP1 sent to UE.
Wherein, after RG obtains address ip 1, can store this address earlier, wait UE to ask again this address ip 1 to be sent to UE after the ipcp negotiation; Perhaps RG stores this address, and after UE request ipcp negotiation, is the IP3 that UE distributes a private network, on RG, safeguards the mapping relations of IP1 and IP3, and through IPCP message the IP3 address is sent to UE.In step S311, carried out respective description.
Step S314, if the updating strategy of needs is arranged, then PCRF can trigger and can carry out the policy update operation between self and BPCF, BNG/BRAS and the BPCF.
Step S315, UE can carry out transfer of data according to from the distributing strategy that network side/this locality configuration is obtained, and is specific as follows:
A) streamed data (specifically referring to step S315): if UE has obtained the IP2 address, UE can select with IP2 address and PERCOM peripheral communication, and data can be passed through the direct and outer net interconnecting of BNG/BRAS like this.That is to say that if UE selects the IP2 address to carry out Operational Visit as source address, then the fixed network gateway will make UE pass through the direct and outer net interconnecting of BNG/BRAS, realize that promptly the general service of fixed network inserts.
The data (specifically referring to step S316) of b) visiting from mobile network (EPS): need visit through the mobile network when UE judges this business datum, then UE can fill out the IP source address of this service message and be that IP1, destination address are the real purpose address of message; RG, BNG/BRAS and mobile network's equipment all carries out routing forwarding to data and gets final product.That is to say that when UE needs directly through the fixed network access external network, generally select the source address of IP2 address as business, the function that so just realizes like existing fixed network directly is linked into external network; And when UE need visit EPS, select the source address of IP1 as business, like this, the fixed network gateway will be linked into EPS with UE when confirming that professional source address is IP1.
If that UE obtains is IP3, then UE can fill out IP source address that should business and be that IP3, destination address are the real purpose address of message; RG is after receiving this message, and according to the IP1 of this locality preservation and the mapping table of IP3, the IP source address of revising message is IP1, carries out routing forwarding then.That is to say that when UE had only obtained the IP3 address, can only be implemented to the access of EPS this moment.
Step 316: will
Among the present invention,, and only obtained the IP3 address, also can realize data distribution at step S313 if UE does not obtain the IP2 address at step S302.At this moment can dispose corresponding distributing strategy at RG; When UE communicates by letter with outer net with IP3; Which IP stream RG can determine directly be linked into outer net from BNG/BRAS according to strategy; Being replaced by the address ip 3 of this part IP stream by BNG/BRAS is the CPE address (upstream is done inverse operation for downstream) that RG distributes, promptly typical NAT operation; Decision needs the IP stream of access mobile core net (EPS) route for RG, is IP1 address (upstream is done inverse operation for downstream) with the IP3 address substitution of corresponding data bag, can realize being linked into EPS.Here, distributing strategy can be to determine according to the type of business should directly insert outer net or insert EPS, as for the business of setting type, can only be linked into EPS, and set the business outside the type for this, inserts EPS or outer net and all can.For example, also can make corresponding access measuring shunt according to the destination address of business, for example, when the address information in the destination address was the address of setting in the tabulation, business can only be linked into EPS, otherwise business can be linked into EPS or outer net.
Certainly, as a kind of feasible implementation, the action that above-mentioned RG carries out also can and realize by the alternative RG of BNG/BRAS.
Below, through concrete application examples, further illustrate the essence of technical scheme of the present invention.
