Abstract

The invention relates to the communication field, and discloses a data service transmission method of a dual-mode terminal and the dual-mode terminal. The method comprises the following steps of: preferably residing in a first network system with higher transmission rate at the beginning of the data service; and estimating the channel quality of the first network system with the higher transmission rate by using the existing data transmission condition as the prior knowledge, comparing the theoretical rate of a second network system, and selecting the network capable of obtaining the highest transmission rate to reside. Under the condition of not increasing the cost nor changing the hardware of the conventional dual-mode terminal, the service data can be transmitted at higher transmission rate, and the user experience can be improved.

Description

technical field [0001] The invention relates to the communication field, in particular to the dual-mode terminal technology in the communication field. Background technique [0002] With the continuous development of communication technology, various types of wireless communication systems have appeared, such as Global System for Mobile communication (Global System for Mobile communication, referred to as "GSM"), Wideband Code Division Multiple Access (Wideband Code Division Multiple Access, referred to as " WCDMA"), Time Division Synchronous Code Division Multiple Access (TD-SCDMA for short), Worldwide Interoperability for Microwave Access (WiMAX for short), Long Term Evolution (Long Term Evolution, referred to as "LTE"), Bluetooth, China Mobile Multimedia Broadcasting (China Mobile Multimedia Broadcasting, referred to as "CMMB") and so on. Among them, the data transmission mode under the GSM network includes General Packet Radio Service (General Packet Radio Service, refe...
