Detailed description of the invention
For under normal circumstances, due to the restriction of standard, if occurring, two are supported CA and identical covering simultaneously
Scene time carrier frequency aggregation configuration failure, terminal cannot activate the problem of auxiliary carrier wave, this expense buy that proposition one
Plant carrier aggregation collocation method, when terminal being carried out carrier aggregation configuration, however, it is determined that go out terminal and be currently located
Community when being overlapping frequency spectrum coverage cell, determine the frequency range that terminal is currently accessed；And it is current according to terminal
The frequency range accessed, configures auxiliary carrier wave for described terminal, according to network environment and the terminal at terminal list label place
Resident concrete frequency range carrys out adaptive selection carrier aggregation allocation plan, for solving under normal circumstances, by
In the restriction of standard, if occurring, during two scenes simultaneously supporting CA and identical covering, carrier frequency aggregation configuration is lost
Lose, the problem that terminal cannot activate auxiliary carrier wave.
Embodiment of the present invention technical scheme main is realized principle below in conjunction with each accompanying drawing, is embodied as
Mode and the beneficial effect that should be able to reach is set forth in.
As in figure 2 it is shown, with frequency range as B38 with as a example by B41.Cover in B38 and B41 overlap and support
In the community of CA, terminal is the most resident to which frequency range, all can configure and carry interior continuous CA, but for
Interband CA, due to the restriction of standard, if directly configuration CA, there will be mistake.As in figure 2 it is shown,
If terminal is resident to B38, when network directly issues the auxiliary carrier activation message activating B39, terminal connects
Receiving the auxiliary carrier activation message activating B39, terminal can be because not supporting the interband carrier wave of B38 Yu B39
It is polymerized and there will be carrier aggregation configuration error.Based on this, the embodiment of the present invention proposes a kind of carrier aggregation and joins
Put method, as it is shown on figure 3, its concrete handling process is the most following:
Step 31, when carrying out carrier aggregation configuration to terminal, it is judged that whether the community that terminal is currently located is
Overlapping frequency spectrum coverage cell, if it is judged that be yes, performs step 32, whereas if judged result is
No, perform step 34.
Can be according to the current traffic load of terminal and the network state of access, it is determined whether need terminal
Carry out carrier aggregation configuration.Such as, if the current traffic load of terminal is bigger, it is determined that need terminal is entered
Row carrier aggregation configures.
Judge whether the community that terminal is currently located is overlapping frequency spectrum coverage cell, can be according to following process side
Formula is carried out:

Secondly, the frequency in the measurement report that current area is measured that the terminal received sends is determined
Information.
Again, determine that the community that terminal is currently located is overlapping frequency spectrum coverage cell according to frequency point information.
Specifically, can be in the measurement report that terminal sends, it is thus achieved that be currently located the frequency range mark of community,
According to obtain frequency range mark, frequency range mark and frequency range attribute corresponding relation in, determine be currently located little
Whether the frequency range attribute that the frequency range mark in district is corresponding is overlapping frequency spectrum.
Specifically, the corresponding relation of frequency range mark and frequency range attribute can be arranged by the way of prestoring.
Whether the frequency range of each frequency range mark correspondence belongs to overlapping frequency spectrum, then be to hold according to the definition in standard
OK.
Step 32, however, it is determined that go out community that terminal is currently located when being overlapping frequency spectrum coverage cell, determine this end
The frequency range that end is currently accessed.
Step 33, the frequency range being currently accessed according to terminal, configure auxiliary carrier wave for terminal.
Wherein, configuring auxiliary carrier wave for terminal, its detailed description of the invention can be according to following two ways:
First kind of way: the auxiliary carrier wave of place, activated terminals current area frequency range, for connecting in this terminal configuration band
Continuous or discrete carrier aggregation.
The second way: by wireless heterogeneous networks (English: Radio Resource Control, abbreviation: RRC)
Connecting the mode heavily joined, by this terminal scheduling to the setting frequency range in addition to being currently accessed frequency range, and activation sets
Determine the auxiliary carrier wave of frequency range, configure auxiliary carrier wave for terminal.
Step 34, however, it is determined that going out the community that terminal is currently located is not overlapping frequency spectrum coverage cell, and terminal is stayed
When staying the community supporting carrier aggregation, send the auxiliary load completing carrier wave configuration for activating auxiliary carrier wave to terminal
Ripple activate message.
Correspondingly, the embodiment of the present invention also proposes a kind of carrier aggregation configuration device, as shown in Figure 4, and including:
First determines unit 401, for when terminal carries out carrier aggregation configuration, determining the current institute of terminal
Community whether be overlapping frequency spectrum coverage cell.
Specifically, above-mentioned first determines unit 401, specifically for determine that the terminal that receives sends to working as
Frequency point information in the measurement report that front community measures, determines the current institute of terminal according to described frequency point information
Community be overlapping frequency spectrum coverage cell.
Second determines unit 402, if determining that unit 401 determines what terminal was currently located for described first
When community is overlapping frequency spectrum coverage cell, determine the frequency range that described terminal is currently accessed；
Dispensing unit 403, for the frequency range being currently accessed according to terminal, configures auxiliary carrier wave for described terminal.
Specifically, above-mentioned dispensing unit 403, it is additionally operable to if it is determined that the community that terminal is currently located is not weight
Folded frequency spectrum coverage cell, and when terminal resides in the community supporting carrier aggregation, send to terminal and be used for activating
Auxiliary carrier wave completes the auxiliary carrier activation message of carrier wave configuration.
Specifically, above-mentioned dispensing unit 403, specifically for activating place, described terminal current area frequency range
Auxiliary carrier wave, configures carrier aggregation continuously or discontinuously in carrying for described terminal.
Specifically, above-mentioned dispensing unit 403, by the way of being connected heavily joined by RRC, by described
