Embodiment Construction

[0026] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0027] In this embodiment, a data transmission method is provided, figure 1 is a flowchart of a data transmission method according to an embodiment of the present invention, such as figure 1 As shown, the process includes the following steps:

[0028] Step S102, the local area network gateway LGW assigns an IP address to the user equipment according to the received configuration information, and saves the IP address and the local area network that the IP address can access, and establishes a secure connection with the access network gateway of the local area network The corresponding relationship of the way;

[0029] In step S104, the LGW transmits data between the user equipment and the area netw...

Abstract

The invention discloses a data transmission method and device. The data transmission method comprises: according to authentication information of user equipment, a local area network gateway (LGW) allocates an IP address to the user equipment, and stores the correlation of the IP address, area networks which the IP address may access, and a manner in which a secure connection is established with access network gateways of the area networks; by means of a secure tunnel, the LGW transmits data between the user equipment and an area network corresponding to the IP address of the user equipment, wherein the secure tunnel is established according to the manner in which the secure connection is established. According to the data transmission method and device provided by the invention, a problem, not taken into consideration in the related art, that different users access different area networks is solved, and different users access different area networks according to allocated IP addresses.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data transmission method and device. Background technique [0002] LTE proposes the concept of heterogeneous network (Heterogeneous Network, referred to as HN), thus evolving some new technologies, and 3GPP (3rd Generation Partnership Project: third generation cooperation project) also conducts special research on this technology, such as local service switching local IP access ( LocalIPAccess, referred to as LIPA), and data offload (SIPTO: SelectedIPTrafficOffload, optional IP service offload), etc., directly exchange local or low-value data services and offload them to the Internet instead of sending them back to the core network for forwarding, avoiding a large number of low-value The impact of valuable services on the core network. [0003] LIPA is proposed based on the Home NodeB (HeNB for short) network. Its core idea is to offload the communication data of the local n...
