Problems solved by technology

[0007] However, in some scenarios, the BBF fixed network cannot always perceive UE access, or the BBF fixed network does not support 3GPP-based access authentication. Can't perceive UE's access, or can't support 3GPP-based access authentication
In this case, BPCF will not be able to actively initiate S9 * The establishment of a session cannot trigger the policy negotiation between the fixed network and the mobile network
It can be seen that the use of the existing technology does not always guarantee the triggering of policy negotiation between the fixed network and the mobile network, and cannot provide stable and reliable support for the subsequent QoS control of UE access based on policy negotiation, resulting in Subsequent implementation of QoS control for UE access based on policy negotiation is full of uncertainties

Embodiment 1

[0045] Image 6 In the S2b access scenario of the present invention, the ePDG and the 3GPPAAAServer / Proxy decide to activate the policy negotiation flow chart with the fixed network. This embodiment is applicable to the case where the fixed network is an untrustworthy non-3GPP access network, and the UE accesses the 3GPP core network through the S2b interface. Image 6 The process includes the following steps:

[0046] In step 601, the UE accesses through the BBF fixed network, and performs 3GPP-based access authentication. This step is optional. When 3GPP-based access authentication is not performed, the UE only needs to perform traditional fixed network access authentication. In this scenario, the BBF access network cannot perceive that the UE accesses the 3GPP core network.

[0047] Step 602, after the UE accesses the BBF access network, the BBF access network allocates a local IP address for the UE.

[0048] In step 603, the UE initiates an IKEv2 tunnel establishment pr...

[0082] Figure 7 In the S2b access scenario of the present invention, the 3GPPAAAServer / Proxy decides to activate the policy negotiation flow chart with the fixed network. This embodiment is applicable to the case where the fixed network is an untrustworthy non-3GPP access network, and the UE accesses the 3GPP core network through the S2b interface. Figure 7 The process includes the following steps:

[0083] Step 701-Step 702: Same as Step 601-Step 602.

[0084] In step 703, the UE initiates an IKEv2 tunnel establishment process and uses EAP for authentication. In the roaming scenario, ePDG interacts with AAAServer through AAAProxy (AAAServer further interacts with HSS) to complete EAP authentication,

[0085] Step 703a, step 703b, step 703c, and step 703d belong to the EAP authentication process. In the non-roaming scenario, execute step 703a, step 703b, and step 703d, and execute step 703a, step 703c, and step 703d in the roaming scenario.

[0086] Step 703a, the DER c...

Embodiment 3

[0104] Figure 8 In the S2c access scenario of the present invention, the ePDG and the 3GPPAAAServer / Proxy decide to activate the policy negotiation flow chart with the fixed network. This embodiment is applicable to the case where the fixed network is an untrustworthy non-3GPP access network, and the UE accesses the 3GPP core network through the S2c interface. Figure 8 The process includes the following steps:

[0105] Step 801-Step 806: Same as Step 601-Step 606.

[0106] Step 807-step 808 are the same as: step 611-step 612.

[0107] In step 809, the UE executes the Bootstraping process. The UE performs DNS lookup according to the APN to obtain the IP address of the P-GW to access the PDN. In order to protect the DSMIPv6 message between UE and P-GW, UE uses IKEv2 to establish a security association and uses EAP for authentication. The P-GW communicates with the AAAServer (the AAAServer further interacts with the HSS) to complete the EAP authentication, and at the same ...

Abstract

The invention discloses a method for triggering fixed-network-mobile convergence strategy negotiation, the method comprising: an evolved packet data gateway (ePDG) initiates establishment of a Gxb session to a policy and charging rule function (PCRF); the PCRF receives the establishment of the Gxb session The PCRF initiates the establishment of an S9* session to the Broadband Policy Control Framework (BPCF), triggering the policy negotiation between the mobile network and the fixed network. The present invention also discloses a system for triggering fixed-network-mobile convergence strategy negotiation. The strategy negotiation triggering unit is used to initiate Gxb session establishment from ePDG to PCRF, and when PCRF is triggered by Gxb session establishment, PCRF initiates to BPCF The establishment of the S9* session triggers the policy negotiation between the mobile network and the fixed network. By adopting the method and the system of the present invention, it can always guarantee to trigger the strategy negotiation between the fixed network and the mobile network under any circumstances.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and system for triggering negotiation of a fixed-network-mobile convergence strategy. Background technique [0002] Such as figure 1 As shown, the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) Evolved Packet System (EPS, Evolved Packet System) network architecture in the non-roaming scenario is composed of Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network (E-UTRAN, Evolved Universal Terrestrial Radio Access Network), Mobility Management Unit (MME, MobilityManagementEntity), Serving Gateway (S-GW, ServingGateway), Packet Data Network Gateway (P-GW or PDNGW, PacketDataNetworkGateway), Home Subscriber Server (HSS, HomeSubscriberServer), Policy and Charging Rule Function (PCRF , PolicyandChargingRulesFunction) entities and other supporting nodes. PCRF is the core of Policy and Charging Control (PCC, Pol...
