Problems solved by technology

[0004] It can be seen that in this handover method, the terminal equipment independently decides whether to perform cell handover, and its disadvantage is that it will cause the network side to lose control of the terminal equipment.
Moreover, during the handover process of a terminal device between two base stations, the base stations need to cooperate with each other. For example, the target base station usually reserves resources for the terminal device to be handed over. Then, if the target base station reserves resources, and the terminal The device has never initiated switching, which will also lead to waste of resources

Embodiment Construction

[0095] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0096] The technical solutions described herein can be used in an LTE system or a fifth generation mobile communication technology (5Generation, 5G) system, and can also be used in a next generation mobile communication system.

[0097] In the following, some terms used in the embodiments of the present invention are explained to facilitate the understanding of those skilled in the art.

[0098] (1) A network device, for example including a base station (for example, an access point), may refer to a device in an access network that communicates with a wireless terminal device through one or more cells on an air interface. The base station can be used to convert received over-the-air frames to and from Internet Protocol (IP) packets, and act as a router between the terminal device and the rest of the access network, which can include an IP netwo...

Abstract

A method and device for cell switching and determining uplink transmission power, used to strengthen the control of network equipment on terminal equipment. One of the cell handover methods includes: the terminal equipment receives an early handover command sent by the network equipment, and the early handover command is used to instruct the terminal equipment to decide whether to perform cell handover; the terminal equipment responds to the downlink signal sent by the network equipment and / or the downlink signal sent by other network equipment, and judge whether to perform cell handover according to the obtained measurement report and the handover condition carried by the early handover command; if the terminal equipment receives the handover command sent by the network equipment, Then the terminal device executes the switching command to switch from the current serving cell to the target cell.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a method and device for cell switching and determining uplink transmission power. Background technique [0002] In a wireless communication system, mobility technology is a key technology. For a terminal device in a connected state, the terminal device can be moved between different base stations through a cell handover process. [0003] Currently, a long term evolution (Long Term Evolution, LTE) system provides a way for a terminal device to perform cell handover. In this way, the source cell instructs the terminal device to measure the source cell and the target cell by itself, and after the measurement, the terminal device independently decides whether to perform cell handover according to the obtained measurement report. [0004] It can be seen that in this handover mode, the terminal equipment independently decides whether to perform c...
