User terminal cross-standard handover control method and device

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...

For a mobile UE, its motion state before and after handover cannot be interacted 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 state of the UE, the new standard will consider the UE to be in a normal motion state, and the subsequent measurement parameters will follow the normal If the motion state is set, there will be a situation where the UE is too late to measure and cause the network to go offline
