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 present invention discloses a data transmission method and device, wherein the method includes: the local area network gateway LGW assigns an IP address to the user equipment according to the authentication information of the user equipment, and saves the IP address and the area that the IP address can visit network, and the way of establishing a secure connection with the access network gateway of the area network; the LGW performs data transmission between the user equipment and the area network corresponding to the IP address of the user equipment through a secure tunnel, wherein, The secure tunnel is established according to the method for establishing the secure connection. The present invention solves the problem in the related art that different users access different area networks, and different users access different area networks according to assigned 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, HN for short), 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 (Local IP Access, referred to as LIPA), and data offload (SIPTO: Selected IP Traffic Offload, optional IP service offload), etc., directly exchange local or low-value data services and offload them to the Internet instead of sending them again Go back to the core network forwarding to avoid the impact of a large number of low-value services on the core network. [0003] LIPA is proposed based on the Home eNodeB (HeNB for short) network. Its core idea is to offload the communication data of the local networ...
