Abstract

The invention discloses a network selection method of a multi-mode terminal. The network selection method comprises the following steps that: the multi-mode terminal resides in a first network, and periodically executes the following operations of: measuring the signal strength E2 of a second network, and obtains a own transmitting power value P2 in the second network and a own transmitting power value P1 in the first network; if the P1 is always greater than the P2 in M continuous periods, and the E2 always meets the minimum requirement of a voice service, switching to or reselecting the second network, otherwise, continuously residing in the first network, wherein M is a positive integer. The invention also discloses a multi-mode terminal. With the method and the device of the invention, the user experience can be improved.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a network selection method for a multi-mode terminal and a multi-mode terminal. Background technique [0002] With the application of third-generation mobile communication (3G) technology, multiple network coverage scenarios appear in the mobile market, because 3G operators often build 3G networks on the basis of their original 2G networks. For example, on the basis of the original Global Mobile Communications (GSM) network, build a Time Division Synchronous Code Division Multiple Access (TD-SCDMA) network, and strive to improve the coverage and capacity of the TD-SCDMA network to the level of the GSM network. Correspondingly, multi-mode terminals have gradually become a key terminal type in the market, and the network selection method of multi-mode terminals has also become a key technology in market operations. [0003] The current network selection methods of multi-mode te...
