Specific embodiment
For under normal conditions, due to the restriction of standard, if occur two and support CA and the scene of identical covering simultaneously
The problem of carrier frequency aggregation configuration failure, terminal can not activate secondary carrier, the present invention proposes a kind of carrier wave aggregation configuration method, right
When terminal carries out carrier wave aggregation configuration, however, it is determined that when the cell that terminal is currently located out is overlapping frequency spectrum coverage cell, determine eventually
Hold the frequency range being currently accessed；And the frequency range being currently accessed according to terminal, secondary carrier is configured for the terminal, according to terminal list label
The resident specific frequency range of the network environment and terminal at place carrys out adaptive selection carrier wave aggregation configuration scheme, leads to for solving
In normal situation, due to the restriction of standard, if occur two supports that carrier frequency aggregation configuration is lost when CA and the scene of identical covering simultaneously
It loses, the problem of terminal can not activate secondary carrier.
Below in conjunction with each attached drawing to the main realization principle of technical solution of the embodiment of the present invention, specific embodiment and
