Problems solved by technology

[0012] but, image 3 , Figure 4 The proposed architecture is only suitable for fixed networks in routing mode, and cannot realize the integration of fixed networks and mobile networks in bridging mode through the S2a interface
[0013] Additionally, in order to achieve image 3 , Figure 4 The proposed architecture uses the UE to directly carry the PPP protocol on the IP layer to perform a simple UE access to EPS through X-MAG, but this method is incorrect and cannot be implemented
Because firstly, PPP is a point-to-point protocol. When BNG / BRAS exists in the path, PPP signaling cannot reach X-MAG; secondly, according to the existing technology, the PPP protocol cannot be directly carried on the IP layer
Therefore, there is currently no image 3 , Figure 4 The specific process of the proposed architecture

Embodiment 1

[0114] Figure 8 It is a schematic diagram of a network architecture in which a UE accesses a mobile network through a bridge-mode fixed network in Embodiment 1 of the present invention, as shown in Figure 8 As shown, in this embodiment, the UE accesses the EPS core network through a fixed network in bridging mode, where the fixed network serves as a trusted non-3GPP access to the EPS, Figure 8 The network architecture shown is a network architecture in a non-roaming scenario. In this embodiment, the X-MAG is connected to the 3GPPAAA through the BBF AAA server / proxy (Server / Proxy) to implement 3GPPAAA-based user access authentication.

[0115] In this embodiment, X-MAG is set between the P-GW of the mobile network and the BNG / BRAS of the fixed network, supports the MAG function in the PMIPv6 protocol, supports the L2TP protocol and the PPP protocol, and communicates with the BNG / BRAS through the Yb interface BNG / BRAS is connected to UE through Ya interface; the settings of...

Embodiment 2

[0125] Figure 9 It is a schematic diagram of a network architecture in which a UE accesses a mobile network through a bridge-mode fixed network in Embodiment 2 of the present invention, as shown in Figure 9 As shown, in this embodiment, the UE accesses the EPS core network through a fixed network in bridging mode, where the fixed network serves as a trusted non-3GPP access to the EPS, Figure 9 The network architecture shown is a network architecture in a non-roaming scenario.

[0126] The difference from Embodiment 1 is that in this embodiment, X-MAG is not connected to 3GPP AAA through BBF AAA server / proxy, but is directly connected to 3GPP AAA to implement user access authentication based on 3GPP AAA. In addition, other aspects of this embodiment (protocol stack settings, interface functions, control signaling interaction, and uplink and downlink data transmission process, etc.) are the same as the functions and principles described in Embodiment 1, and will not be descr...

Embodiment 3

[0128] Figure 10 It is a schematic diagram of a network architecture in which a UE accesses a mobile network through a bridge-mode fixed network in Embodiment 3 of the present invention, as shown in Figure 10 As shown, in this embodiment, the UE accesses the EPS core network through a fixed network in bridge mode, wherein the fixed network serves as a trusted non-3GPP access to the EPS. Figure 10 The network architecture shown is the network architecture of roaming scenarios and home routing, including home public land mobile network (homePublic Land Mobile Network, hPLMN) and visited PLMN (vPLMN). BPCF is connected to hPCRF through vPCRF, and vPCRF and hPCRF are connected through roaming interface S9 interface BBFAAA server / agent is connected with 3GPP AAA and HSS through 3GPP AAA agent; correspondingly, in this embodiment, X-MAG is connected with 3GPP AAA agent and 3GPP AAA through BBF AAA server / agent, so as to realize user access based on 3GPPAAA authentication.

Abstract

The invention discloses a system and a method for combining a fixed network and a mobile network. The system is characterized in that: aiming at the fixed network in a bridge pattern, an X-mobile anchor gateway (X-MAG) used for realizing trusted non 3rd generation partnership project (3GPP) access is arranged and connected between the fixed network and the mobile network, a Ya interface is arranged between user equipment (UE) and a broadband network gateway / broadband remote access server (BNG / BRAS), and a Yb interface is arranged between the BNG / BRAS and the X-MAG, so the UE can access an evolved packet system (EPS) of the mobile network by the fixed network in the bridge pattern through the X-MAG in a trusted non 3GPP IP access way; and aiming at the fixed network in a route pattern, a point-to-point protocol (PPP) signaling is borne by supporting the use of a layer 2 tunneling protocol (L2TP) on a terminal and the X-MAG based on the conventional framework. By the system and the method, the UE can realize the trusted non 3GPP access in a simple and feasible way, namely the UE can access the mobile network through the fixed network in the bridge pattern or the route pattern, and the combination between the fixed network and the mobile network is realized.
