Problems solved by technology

[0004] However, in CHO, since the CHO command can only be triggered based on conditions, the conditions for applying the CHO command are not met for a long time, and during this time period, the general system information (common SI) of the candidate base station about access When the system information has changed, when this situation occurs, even if the conditions for applying the CHO command are satisfied, the terminal will apply the CHO command to switch to the alternative base station, and the access will fail

Embodiment Construction

[0073] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0074] First, some terms used in this application are explained.

[0075] The "first device" mentioned in this application specifically refers to the serving base station that establishes a communication connection with the terminal during the mobility management process. The serving base station can make a handover decision for the terminal according to the measurement report of the terminal. The serving base station can also Called the source base station.

[0076] The "second device" referred to in this application specifically refers to a candidate base station that can provide a communication connection for the above-mentioned terminal during the mobility management process, and the terminal can switch from the above-mentioned first device to the candidate base station....

Abstract

The embodiment of the invention provides a communication method and communication equipment. The communication method comprises the following steps that a first device sends a switching request message to a second device, and receives a switching confirmation message returned by the second device, wherein the switching confirmation message carries general system information of the second device; the first device sends a switching instruction to a terminal, wherein the switching instruction comprises general system information of the second device; and the first device sends a second message tothe terminal according to the first message, wherein the first message is sent by the second device, and the first message is used for indicating the change of the general system information of the second device, so that the terminal obtains the changed communication system information of the second device according to the second message. According to the embodiment of the invention, a switchingfailure can be avoided, and the switching success rate is improved.

Description

technical field [0001] The embodiments of the present application relate to communication technologies, and in particular, to a communication method and device. Background technique [0002] Handover in mobile communication means that when the terminal is transmitting information with the base station, due to various reasons, such as poor channel transmission quality, balanced business, etc., it needs to transfer from the originally used channel to a more suitable channel for information. The process of transmission. [0003] In the handover (Handover, HO) of the 3rd Generation Project Partner (3GPP) standard version 14 (Release-14), the source base station will access the target base station through a radio resource control (Radio Resource Control, RRC) connection reconfiguration message The required system information is sent to the terminal, and the terminal needs to perform reconfiguration and establish a connection with the target base station according to the RRC conn...
