Embodiment 1

[0115] Figure 4It is a schematic diagram of the steps of this embodiment. This embodiment is a process of switching from simple IP-based wireless cellular access network access to wireless LAN access. This process corresponds to the fact that there is no IPSEC SA between the terminal and the wireless LAN access gateway, and it needs to be established through renegotiation through the IKEv2 process.

[0116] The terminal has established a connection between the wireless cellular access network and the packet data gateway of the core network, and is using data services. When the terminal detects the WLAN signal and decides that the service connection needs to be switched to the WLAN access, the terminal first sends the IKE SA initial message to the WLAN access gateway; after receiving the access request, the WLAN access gateway sends the AAA server / The home user server initiates a user authentication request; the AAA server / home user server calculates the authentication param...

Embodiment 2

[0120] Figure 5 It is a schematic diagram of the steps of this embodiment. This embodiment is a process for a terminal to switch from a simple IP-based wireless local area network access to a wireless cellular access network.

[0121] The terminal has established a connection with the packet data gateway of the core network through the wireless local area network, and is using the service. When the terminal judges that the service connection needs to be switched to the wireless cellular access network, the terminal interacts with the wireless cellular access network, triggers the establishment of the air link and the link establishment process to the packet data gateway of the core network, and establishes the wireless cellular access network The service channel to the packet data gateway of the core network; after the packet data gateway of the core network is completed and the service channel of the wireless cellular access network is established, the wireless LAN access g...

Embodiment 3

[0125] Image 6 It is a schematic diagram of the steps of this embodiment. This embodiment is the flow of the terminal switching from wireless cellular access network access based on PMIP (proxy mobile IP) to wireless LAN access. This process corresponds to the fact that there is no IPSEC SA between the terminal and the wireless LAN access gateway, and IKEv2 is required. The process renegotiates the established situation.

[0126] The difference between PMIP-based and simple IP-based processes lies in the different messages exchanged between the packet data gateway of the core network and the wireless LAN access gateway; the PMIP-based wireless cellular access network is switched to the wireless LAN, and the wireless LAN access The packet data gateway of the core network initiates a PMIP binding update (PMIP Binding Update) message, and the packet data gateway of the core network returns a PMIP binding response (PMIP Binding Ack) message to the wireless LAN access gateway. T...

Abstract

The invention relates to a mobile communication network and a switching method of a terminal between a wireless local area network and a wireless cellular access network, which solve the problem of switching of the terminal between the conventional wireless local area network and wireless cellular access network. The mobile communication network comprises a core network, a wireless local area network, a connection core network, and a wireless local area network access gateway and a wireless cellular access network of the wireless local area network; the core network comprises a grouped data gateway; and the terminal in the wireless local area network is accessed to the grouped data gateway of the core network through the wireless local area network access gateway.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a mobile communication network and a switching method of a terminal. Background technique [0002] FMC (Fixed Mobile Convergence) combines the bandwidth advantages of fixed networks with the mobile advantages of mobile networks, enabling users to use the same terminal to access the core network through different Move and switch freely under the coverage of the inbound network, and obtain complete services and consistent service experience. [0003] With the development of FMC technology and the increasingly urgent demand for converged services based on 3GPP and non-3GPP (including wireless LAN) wireless access technologies, to solve the problems of high bandwidth costs and poor indoor network coverage existing in 3GPP mobile wireless access networks, It is more convenient for users to use various wireless access technologies anytime and anywhere, seamlessly and fre...
