CHANNEL SELECTION METHOD AND DEVICE
First Claim
1. A serving device, comprising:
- a processor configured to;
acquire a candidate unlicensed channel;
determine an available unlicensed channel from the candidate unlicensed channel wherein the available unlicensed channel is an unlicensed channel that is not interfered or on which a strength of an interference signal is less than an interference detection threshold; and
acquire a first operation channel from the available unlicensed channel wherein the first operation channel is a channel on which the serving device performs communication with a terminal in a wireless cellular network mode;
wherein the serving device further comprises a receiver configured to receive an identifier of the candidate unlicensed channel sent by a primary serving device or an operation administration and maintenance (OAM) device, or receive an identifier of a manually configured candidate unlicensed channel; and
the processor is further configured to;
acquire the candidate unlicensed channel according to the identifier of the candidate unlicensed channel received by the receiver; and
acquire the first operation channel from the available unlicensed channel.

Abstract
The present invention discloses a channel selection method and device and relates to the communications field, so as to resolve a problem of applying an unlicensed spectrum to a wireless cellular network. The channel selection device is configured to acquire a candidate unlicensed channel, determine an available unlicensed channel from the candidate unlicensed channel, where the available unlicensed channel is an unlicensed channel that is not interfered or on which a strength of an interference signal is less than an interference detection threshold, and acquire a first operation channel from the available unlicensed channel, where the first operation channel is a channel on which the channel selection device performs communication with user equipment in a wireless cellular network mode.

11. A channel selection method, comprising:
-
acquiring, by a secondary serving device, a candidate unlicensed channel; determining, by the secondary serving device, an available unlicensed channel from the candidate unlicensed channel, wherein the available unlicensed channel is an unlicensed channel that is not interfered or on which a strength of an interference signal is less than an interference detection threshold; and acquiring, by the secondary serving device, a first operation channel from the available unlicensed channel, wherein the first operation channel is a channel on which the secondary serving device performs communication with equipment terminal in a wireless cellular network mode;
wherein the acquiring, by a secondary serving device, a candidate unlicensed channel comprises;receiving, by the secondary serving device, an identifier of a candidate unlicensed channel sent by a primary serving device or an operation administration and maintenance (OAM) device, or acquiring, by the secondary serving device, an identifier of a manually configured candidate unlicensed channel. - View Dependent Claims (12, 13, 14, 15)
