Abstract

The present invention discloses a method, device and system for configuring a carrier aggregation function. The method includes: when a network-side device determines that access bands supported by a terminal are a first band and a second band and a supported carrier aggregation band combination is a carrier aggregation band combination related to the second band according to access band information and carrier aggregation band combination information supported by the terminal, judging whether to configure a carrier aggregation function related to the second band for the terminal; and if so, sending a reconfiguration signaling to the terminal, to guide the terminal to be switched into the second band of the same cell, and after determining that the reconfiguration of the terminal is completed, configuring a carrier aggregation function related to the second band for the terminal, thereby solving the problem that the current network-side device cannot accurately configure a carrier aggregation function related to a second band for a terminal supporting access capabilities of first and second bands and supporting the carrier aggregation function related to the second band, and improving the application ratio and application effect of the carrier aggregation function related to the second band.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular to a configuration method, device and system for a carrier aggregation function. Background technique [0002] At present, there are two frequency bands on the 2.6G frequency band, the mainstream frequency band of LTE (Long Term Evolution, long-term evolution), one is frequency band 41 (Band41, 2500MHz-2690MHz), and the other is frequency band 38 (Band38, 2570MHz-2620MHz). Among them, The 2570MHz-2620MHz frequency bands overlap completely, but the radio frequency indicators of frequency band 38 and frequency band 41 are different. [0003] Specifically, since the existing stock terminals are terminals that only support frequency band 38 (such as terminals that only support 2575MHz-2615MHz), in order to better support frequency band 41, such as 2615MHz-2635MHz, it is necessary to configure the terminal to support frequency band 41, At the same time, in ord...
