If UE is multi-carrier polymerizing terminal, because carrier aggregation is by the component carrier (Component of two or more
Carriers, referred to as CC) it is aggregating, so the signal intensity for defining each component carrier is respectively S1, S2 ... Sn
(wherein, the carrier number of the largest component that n is supported by carrier aggregation terminal), when terminal opens carrier data task,
The current each component carrier network signal of terminal automatic detection, and according to predetermined threshold value S comparing result judging each point
Whether amount carrier signal is in weak signal state.
If S1>S, S2>S…Sn>S, wherein all component carriers are not in weak signal state, terminal is then according to acquiescence
Normal carrier wave converging network carry out data task.
If S1<S, S2<S…Sn<S, wherein all component carriers are all in weak signal state, terminal then closes all loads
The data task of ripple polymerization.
If wherein there are one or more component carriers, m (m ＜ n) individual component carrier is defined as in low signal areas,
Then turn off the data link of the m component carrier in weak signal state, data are carried out with each carrier wave of remaining n-m and is appointed
Business.By taking dual carrier polymerization as an example, if S1>S, S2<S, then component carrier 1 is not in weak signal state, component carrier

Three carrier aggregations are downloaded；If three component carrier S1, signal intensity both less than threshold value S of S2, S3, then three points
Loading gage ripple can then be closed all carrier links and not carry out data service all in weak signal state, then terminal；If S1>S,
S2>S, S3<S, i.e. 1 component carrier and 2 component carrier signals intensity are all relatively good, and 3 component carriers are in weak signal shape
State, now according to situation about reporting, terminal can close the link worked by 3 component carriers, only carry out 1 component carrier and
The data service of 2 component carrier aggregations；By that analogy, same other combined situations are similar.
More specifically, it is assumed that S=-115dBm, in the S1=-100dBm detected into terminal in certain cell,
S2=-108dBm, S3=-95dBm, from S1, the size contrast of S2, S3 and threshold value S may determine that component carrier 1 and
3 RST of component carrier is good, and component carrier 2 is under weak signal state, and now terminal is closed according to judged result
Lose weight the link of carrier wave 2, only carries out data service to component carrier 1 and the polymerization of component carrier 3.If then tested
Signal to S2 improves, and when more than -115dBm, then the polymerization for recovering component carrier 3 carries out data service.
