Embodiment Construction

[0062] In order to make the purpose, technical solution and advantages of the application clearer, the application will be further described in detail below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0063] In view of the problem in the prior art that a terminal in the ECO state in a 5G system has a large signaling overhead when inter-system cell reselection occurs, an embodiment of the present application provides a method for inter-system cell reselection, a terminal, and a network side When the terminal in the first connection state performs the cell reselection process from the base station of the 5G system to the base station of the 4.5G system or 4G system (re...

Abstract

The invention discloses a cell reselection method between different systems, a terminal and a network side device. The method comprises the following steps: the terminal sends a first request messageto a first base station, wherein the first request message carries first reason indication information, the first reason indication information characterizes that the terminal needs to execute a cellreselection process from a second base station to the first base station, the first base station is located in a first radio access technology (RAT) system, the second base station is located in a second RAT system, the terminal is in a first connection state when connecting the second base station, and the first RAT system does not support the first connection state; the terminal receives a replymessage of the first request message returned by the first base station, and converts the first connection state into a second connection state according to the reply message, wherein the first RAT system supports the second connection state.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a method, terminal and network side equipment for inter-system cell reselection. Background technique [0002] With the increasing number of mobile communication users and the ensuing demand for service bandwidth, mobile communication technology needs continuous innovation. In the process of innovation, the characteristics of mobile communication are clearly reflected, and more wireless Access technology (English: Radio Access Technology, abbreviation: RAT) system type. For example, the third-generation mobile communication technology (ie, 3G) network and the fourth-generation mobile communication technology (ie, 4G) network have been widely used in most countries. Long Term Evolution (English: Long Term Evolution, abbreviation: LTE) is the mainstream technology of 4G networks. In order to widely use LTE in enterprise applications, enterprise LTE (English: e...
