Situation can difference, therefore there is the overlapping of band segment in definition, as indicated with 1, frequency range B41 is practical with B38 and B7
Equal spectrum overlappings.
According to the regulation of 3GPP, even if frequency spectrum is overlapping cases, terminal is individually designed for different frequency range in design
Radio-frequency front-end telecommunication circuit.Under non-carrier aggregation scene, network is by broadcasting the frequency point number of the frequency range of overlapping or passing through
The modes such as mFBI instruction, the spread spectrum scenarios that notice terminal current area uses, terminal are independently resident some according to corresponding information
The cell of frequency point.
In the case where carrier wave polymerize (CA) scene, there is different frequency range different CA to combine, such as B38 frequency range, only
It is combined with interior continuous CA (CA_38C), and for B41 frequency range, then it include with interior continuous CA (CA_41C) and interband CA (CA_
39A-41A) combination etc..When network carries out CA activation to terminal, according to current normal process, terminal, which is resident, supports CA's
After cell, network directly issues the activation that CA is completed in activation secondary carrier order to terminal configuration secondary carrier.The process is not for depositing
Be possible in the case where overlapped frequency bands covering, if but occur two simultaneously when supporting CA and the scene of identical covering, should
Normal process will will lead to CA and can not activate.

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 solution, autonomous by terminal
Judgement to carrier wave aggregation configuration tenability and network environment is matched to realize that whose product access switches and completes carrier wave polymerization
It sets, for solving under normal conditions, due to the restriction of standard, if load when occurring two while supporting CA and the scene of identical covering
The problem of frequency aggregation configuration failure, 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
Its beneficial effect corresponding to reach is set forth.
As shown in Fig. 2, by taking frequency range is B38 and B41 as an example.In the cell of B38 and B41 overlapping covering and support CA, eventually
Which frequency range no matter end be resident, and can configure with interior continuous CA, but for interband CA, due to the limitation of standard, if
Directly configuration CA then will appear mistake.As shown in Fig. 2, network directly issues the auxiliary load of activation B39 if terminal is resident B38
When wave activate message, terminal receives the secondary carrier activate message of activation B39, and terminal can be because do not support the interband of B38 and B39
Carrier wave polymerize and will appear carrier wave aggregation configuration mistake.Based on this, the embodiment of the present invention proposes a kind of carrier wave aggregation configuration method,

Each frequency range identifies whether corresponding frequency range belongs to overlapping frequency spectrum, then is executed according to the definition in standard.
Step 34, however, it is determined that go out not supporting the carrier wave aggregation configuration, then judge cell that terminal is currently located whether be
Overlapping frequency spectrum coverage cell, if it is judged that be it is yes, then follow the steps 35, whereas if judging result be it is no, then execute step
Rapid 38.
Step 35, however, it is determined that when the cell that terminal is currently located out is overlapping frequency spectrum coverage cell, terminal switches to overlapping
Frequency range.
Wherein, the radio-frequency front-end access of terminal switches to overlapped frequency bands.
Step 36, the secondary carrier in the corresponding carrier wave polymerization of activation overlapped frequency bands, completes carrier wave aggregation configuration.
Step 37, however, it is determined that when going out terminal and supporting the carrier wave aggregation configuration, according to the secondary carrier activate message received,
Secondary carrier is activated to complete carrier wave aggregation configuration.
Step 38, the configuration without carrier wave polymerization secondary carrier.
Correspondingly, the embodiment of the present invention also proposes a kind of carrier wave aggregation configuration device, as shown in Figure 4, comprising:
