Embodiment Construction

[0026] The basic idea of ​​the present invention is: when the terminal needs to switch networks, it sorts the target cells corresponding to the source cell in the historical record that matches the currently leaving cell to form a search list, selects the target cell according to the search list and accesses it.

[0027] Here, the historical record is the handover record between different network standards saved by the terminal, including: the source cell information and the corresponding target cell information at the time of handover, and the number of successful handovers from the source cell to the target cell; the source cell refers to Due to the deterioration of the network signal, the connection with the terminal cannot be maintained, and the terminal leaves the cell. The source cell information includes: the identity of the source cell; the target cell refers to the cell that provides the terminal with a network signal and maintains the connection, and the terminal enter...

Abstract

The invention discloses a method for switching different network systems. The method comprises the following steps of: when a terminal needs to be switched, ordering target cells corresponding to a source cell in accordance with a current leaving cell in the historical records to form a search list, selecting a target cell according to the search list and accessing the target cell. The invention also discloses a device for switching the different network systems. The method and the device improve the switching speed between the different network systems, promote user experience and reduce power consumption of the terminal.

Description

technical field [0001] The invention relates to the field of wireless communication network switching, in particular to a method and device for switching between different network standards. Background technique [0002] With the development of modern wireless communication technology, more and more network standards have been widely used. For example, the commonly used network standards are: Global System for Mobile Communications (GSM), Wideband Code Division Multiple Access (WCDMA), High Speed ​​Data Packet Access (HSPA), Code Division Multiple Access (CDMA) 2000, EVDO ( Evolution Data Only), Worldwide Interoperability for Microwave Access (WiMAX), Long Term Evolution (LTE), etc. [0003] Some of the many network standards have formulated interconnection standards, which can realize dual-mode switching between different network standards, that is, switching between different network standards without affecting user use; for example, LTE has formulated standards for commu...
