Problems solved by technology

For a mobile UE, its motion state before and after handover cannot be interacted in time, resulting in poor service continuity of the UE

Embodiment Construction

[0043] In the current cross-standard handover scenario, when the UE switches to a new standard, the new standard will consider the UE to be in a normal (low-speed or stationary) motion state, and the subsequent measurement and handover will follow the UE’s low-speed or static state. Rules If it is too late to measure the target cell, it is easy to be disconnected from the network.

[0044] In the embodiment of the present invention, when the network side sends the cross-mode switching indication message to the user terminal, it carries the movement state indication information of the user terminal under the first standard, so that the user terminal can know its own current movement state. After the user terminal is switched to the second standard, in the connection state of the second standard, when the user terminal is in a high-speed motion state or a medium-speed motion state, the waiting time between successfully camping in the cell and initiating the neighbor cell measuremen...

Abstract

The invention discloses a method and a device for controlling cross mode switching for user equipment. The method comprises steps: whether a cross mode switching indication message sent by a network side in a first mode is received is judged; when the cross mode switching indication message is received, motion state indication information is acquired from the cross mode switching indication message; and when a second mode is switched successfully, according to the motion state indication information, operation of a connection state under the corresponding motion state is executed, wherein the operation of the connection state comprises adjacent area measurement operation and adjacent area measurement report reporting. By adopting the method and the device of the invention, out of system can be prevented from happening to the user equipment during the different network mode switching process.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a user terminal cross-standard handover control method and device. Background technique [0002] In the existing solution, the cross-system handover of the user equipment (UE) usually measures the target cell according to the different system measurement information configured on the network side, reports the measurement results as needed, and sends a handover instruction from the network side to instruct the UE to switch to the target cell. district. [0003] In the scenario where 2G, 3G, and 4G coexist, cross-standard switching often occurs. For a mobile UE, the motion states before and after the handover cannot be exchanged in time, resulting in poor service continuity of the UE. [0004] For example, if the UE is in a high-speed motion state before switching, when the UE is switched to another standard, since the new standard does not know the current motion st...
