Problems solved by technology

[0010] The above is a method of loose coupling between protocol stacks. The problem with this method is that user data in the packet switching domain (PS domain) needs to be processed by two sets of protocol stacks, and the IP data is packaged twice, and requires Separately develop a user plane control layer for data forwarding, the efficiency is relatively low

Embodiment Construction

[0039]In fact, when a multi-mode mobile phone establishes an IP connection with the Internet through a mobile communication protocol stack, and establishes an IP connection with other terminals such as a notebook through a WLAN protocol stack at the same time, the underlying data format transmitted between the two connections is an IP packet , therefore, it is possible to find a simple conversion method between data packets through IP address mapping.

[0040] According to the method of the present invention, when the notebook is connected to the multi-mode mobile phone through the WLAN micro-network, and the Internet service is performed through the multi-mode mobile phone, after the PDCP layer of the mobile communication protocol stack of the multi-mode mobile phone decompresses the Internet IP data packet, IP address translation is performed , convert the destination IP address of the IP data packet into the IP address of the notebook in the WLAN micro-network, and directly ...

Abstract

The invention discloses a multimode terminal and a data transmitting method thereof. The multimode terminal of the invention is provided with at least one mobile communication protocol stack, one wireless local area network protocol stack, a shared buffer area and a transmitting controller, wherein, the mobile communication protocol stack is used for storing IP data packet received from the internet to the shared buffer area and then informing the transmitting control layer; the transmitting control layer is used for informing the wireless local area network protocol stack storage address of the IP data packet in the shared buffer area; the wireless local area network protocol stack is used for taking the IP data packet out of the share buffer area and sending the IP data packet to a radio installation, and anyone of the mobile communication protocol stack, the transmitting control layer and the wireless local area network protocol stack modifies target IP address of the IP data packet to be the IP address of the radio installation in the wireless local area network connection. The multimode terminal and data transmitting method of the invention can effectively improve data transmission utilization.

Description

technical field [0001] The invention relates to a mobile communication technology, in particular to a multi-mode terminal and a data forwarding method thereof. Background technique [0002] The development of today's science and technology has brought a variety of wireless access technologies and cellular communication technologies, and the next generation network will appear a mixed network environment supported by a variety of different wireless technologies. A mobile communication terminal that can use or support multiple wireless networks in a variety of cellular mobile communication networks or wireless access networks is called a "multi-mode mobile communication terminal", hereinafter referred to as a "multi-mode terminal". At present, multi-mode fusion of mobile terminals has become a development trend of mobile communication terminals. [0003] Existing multi-mode terminals generally include cellular mobile communication network (PLMN) modules, such as TD-SCDMA, WCD...
