摘要： Embodiments of the present invention disclose a handover method and system of a dual-mode communication terminal, so as to implement that during a handover, an IP address is not released, a session continues and a user is unaware. A first mode and a second mode of the dual-mode communication terminal adopt a master-slave universal serial bus USB driver structure. The methods includes: A host triggers initiating of network access to a second network by the dual-mode communication terminal; the host maintains occupation of an IP address which is in a first network by the dual-mode communication terminal, and obtains an Internet protocol IP address which is of the dual-mode communication terminal and in the second network; if the IP address in the second network is the same as a current IP address which is of the dual-mode communication terminal and in the first network, the host uses, in the second network, the IP address.

摘要： The present invention provides a communication mode selection method, which includes: when a state parameter of a communication terminal meets a predetermined condition, selecting a mode corresponding to a spatial multiplexing technique as a mode for communication between the terminal and a corresponding base station, where the predetermined condition at least includes that the number of antennas is greater than 1. This prevents the terminal from entering a MIMO B mode in the case of using a single antenna, so that repeated switching between a MIMO A mode and the MIMO B mode may not occur, and therefore, the problem of service jittering caused by repeated switching is avoided.

摘要翻译： 本发明提供一种通信模式选择方法，其包括：当通信终端的状态参数满足预定条件时，选择与空间复用技术相对应的模式作为终端与相应基站之间的通信模式，其中 预定条件至少包括天线数量大于1.这样，在使用单个天线的情况下，这防止终端进入MIMO B模式，使得在MIMO A模式和MIMO B模式之间的重复切换可以 不会发生，因此避免了由重复切换引起的服务抖动的问题。
