Embodiment 1

[0105] Figure 15 It is the flow of the frequency band replacement method according to Embodiment 1 of the present invention Figure 1 ,Such as Figure 15 As shown, the process includes the following steps:

[0106] Step S1502, the terminal detects that the strength of the wireless signal sent from the second base station on the first frequency band is higher than the threshold, wherein the terminal accesses the first base station and performs wireless communication with the first base station on the first frequency band;

[0107] Step S1504, the terminal reports to the first base station the identification information of the second base station obtained from the signal sent by the second base station;

[0108] Step S1506, the first base station determines the address of the second base station according to the identification information of the second base station;

[0109] Step S1508, the first base station sends a frequency band change request to the second base station. ...

Embodiment 2

[0133] Figure 17 It is a flow chart of the frequency band replacement method according to Embodiment 2 of the present invention, such as Figure 17 As shown, the process includes the following steps:

[0134] Step S1702, the terminal detects that the strength of the wireless signal sent from the second base station on the first frequency band is higher than the threshold, wherein the terminal accesses the first base station and performs wireless communication with the first base station on the first frequency band;

[0135] Step S1704, the terminal reports to the first base station the identification information of the second base station obtained from the signal sent by the second base station;

[0136] Step S1706, the first base station sends the identification information of the second base station to other network devices, so that other network devices can send a frequency band change request to the second base station according to the information;

[0137] In step S170...

Embodiment 3

[0145] Figure 18 It is a flow chart of the frequency band replacement method according to Embodiment 3 of the present invention, such as Figure 18 As shown, the process includes the following steps:

[0146] Step S1802, the terminal detects that the strength of the wireless signal sent from the second base station on the first frequency band is higher than the threshold, wherein the terminal accesses the first base station and performs wireless communication with the first base station on the first frequency band;

[0147] Step S1804, the terminal reports to the first base station the identification information of the second base station obtained from the signal sent by the second base station;

[0148] Step S1806, the first base station sends an instruction to the terminal according to the identification information of the second base station, and triggers the terminal to use a specific frequency band change request resource to send a signal. The signal may include a physi...

Abstract

Provided are a frequency band replacement method and device, the method comprising: a first base station receives identifier information used to identify a second base station, the identifier information being transmitted by a terminal after an intensity of a wireless signal transmitted by the second base station in a first frequency band is determined to be higher than a threshold, and the terminal pre-accessing the first base station and communicating with the first base station by using the first frequency band; and the first base station triggers, according to the identifier information, a procedure of transmitting a frequency band replacement request to the second base station. The present invention addresses the problem of serious communication interference caused by the same frequency band being used by a plurality of individuals or carriers to provide a wireless communication service in the related techniques, and in turn reduces communication interference.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for changing a frequency band. Background technique [0002] The wireless communication in the related art includes the wireless communication carried out on the authorized licensed frequency band and the unlicensed Unlicensed frequency band. The wireless communication carried out on the licensed frequency band is for example the communication provided by the current mobile communication operators (such as China Mobile). The frequency band occupied by wireless communication is exclusively used by a mobile communication operator (hereinafter referred to as the operator), and the operator manages and optimizes the frequency band resources (such as controlling the density of access devices working in the frequency band, transmission power , antenna inclination, etc.), so as to ensure the reliability and effectiveness of wireless communication services provided ...
