Embodiment Construction

[0032] 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.

[0033] 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:

[0034] 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 corresponding relationship between the IP address and the local area network that the IP address can access;

[0035] Step S104, the LGW performs data transmission between the user equipment and the area network corresponding to the IP address of the user equipment according to the correspondence....

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 and area networks which the IP address may access; the LGW transmits data between the user equipment and an area network corresponding to the IP address of the user equipment according to the correlation. 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] In traditional wireless network data exchange, the data of the base station is transmitted back to the core network, and then the core network sends the data to the base station. Even if two users are under the same base station, they still need to be transmitted back to the core network for forwarding. When the network evolves into the Long Term Evolution (LTE for short) era, the data traffic becomes larger and larger, and the forwarding mode of the traditional core network is not suitable for the development direction of the network. [0003] LTE proposes the concept of heterogeneous network (Heterogeneous Network, referred to as HN), thus evolving some new technologies, and the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) also conducts special research on this...
