Embodiment Construction

[0039] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. In the subsequent description herein, MS (Mobile Station, mobile station) is a specific example of a user terminal, which belongs to the same concept as the user terminal.

[0040] refer to figure 2 , is a schematic diagram of a user plane protocol stack framework embodiment of the present invention. In the embodiment of the present invention, the data transmission between the MS and the GANC is based on the IP bearer, and the data transmission between the GANC and the MGW is also based on the IP bearer. That is, the A port is IP-based, and the user plane data packet is encapsulated in the RTP protocol data packet and transmitted between the MS and the MGW through the IP bearer. The GANC relays or routes the IP data packet carrying the RTP protocol data packet. Under the framework of this agreement:

[0041] On the MS side, in the IPsec Tunnel...

Abstract

The invention discloses a data transmission method. The method comprises that: a user terminal acquires IP layer information of a core network element, wherein the IP layer information of the core network element comprises IP address information of the core network element; and the IP address of the core network element is used as a destination IP address of data transmission so as to carry out transmission of a user plane data packet. An MGW acquires IP layer information of the user terminal, wherein the IP layer information of the user terminal comprises IP address information of the user terminal; and the IP address of the user terminal is used as a destination IP address of data transmission to carry out transmission of a user plane data packet. The invention also discloses the corresponding user terminal and network equipment. The user terminal and the core network element carry out the transmission of the user plane data packet based on an IP loading mode, and an access network element (GANC) relays, routes and forwards the IP data packet so as to reduce the transmission time delay, improve the transmission efficiency of user plane data and reduce the data processing burden of an access network.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data transmission method, user terminal and network equipment. Background technique [0002] Under the GAN (Generic Access Network, Generic Access Network) / EGAN (Enhanced Generic Access Network, Enhanced Generic Access Network) protocol framework defined by 3GPP (Third Generation Partnership Project, Third Generation Partnership Project), terminal devices can pass IP access technology is connected to the wireless network. For example, the terminal can be connected to the GAN network controller GANC (GANC Generic Access Network Controller) through the wireless local area network WLAN and Internet, and connected through the A / Gb and Iu interfaces. Access to the wireless core network enables operators to easily deploy 2G and 3G services. [0003] In the GSM network, the MSC (Mobile Switch Center) of the access network and the core network transmits service data through the A int...
