Abstract
The invention discloses a carrier wave polymerization configuration method and an apparatus thereof. The method comprises the following steps that when receiving an auxiliary carrier wave activation message used for activating an auxiliary carrier wave to complete carrier wave configuration, a terminal determines whether to support carrier wave polymerization configuration; when the terminal is determined not to support the carrier wave polymerization configuration and a cell where the terminal is located currently is an overlapping frequency spectrum coverage cell, the terminal is switched to an overlapped frequency range; the auxiliary carrier wave in carrier wave polymerization corresponding to the overlapped frequency range is activated so as to complete carrier wave polymerization configuration. Generally, because of limitation of a standard, if two scenes which simultaneously support CA and have same coverage appear, carrier frequency polymerization configuration is failed and the terminal can not activate the auxiliary carrier wave. By using the method and the apparatus of the invention, the above problem is solved.

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 the failure of carrier frequency aggregation configuration, terminal cannot activate the problem of auxiliary carrier wave, and the present invention proposes a kind of solution
Certainly scheme, by terminal independently to carrier aggregation configuration tenability and the judgement of network environment, realizes
Whose product path switches and completes carrier aggregation configuration, for solving under normal circumstances, due to the restriction of standard,
If there is carrier frequency aggregation configuration failure during two scenes supporting CA and identical covering simultaneously, terminal cannot swash
The problem of auxiliary carrier wave alive.
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, terminal is resident to community.
Step 32, terminal receives the auxiliary carrier wave completing carrier wave configuration for activating auxiliary carrier wave of network side transmission and swashs
Message alive.
Step 33, receives the auxiliary carrier activation message completing carrier wave configuration for activating auxiliary carrier wave in terminal
Time, it may be judged whether support carrier aggregation configuration.If it is judged that be no, then perform step 34, otherwise,
If it is judged that for be then execution step 37.
Wherein, the frequency point information of present access subzone is measured by terminal, according to measurement result, determines end
The community that end is currently located is overlapping frequency spectrum coverage cell.
Specifically, current area is measured by terminal, it is thus achieved that measurement report.Determine the frequency in measurement report
Dot information.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 obtained, it is thus achieved that be currently located the frequency range mark of community, according to
The frequency range mark obtained, in the corresponding relation of frequency range mark and frequency range attribute, determines and is currently located community
Whether the frequency range attribute of frequency range mark correspondence 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 34, however, it is determined that go out and do not support that described carrier aggregation configures, then judge the community that terminal is currently located
Whether it is overlapping frequency spectrum coverage cell, if it is judged that be yes, then performs step 35, whereas if sentence
Disconnected result is no, then perform step 38.
Step 35, however, it is determined that going out community that terminal is currently located when being overlapping frequency spectrum coverage cell, terminal switches
To overlapped frequency bands.
Wherein, the radio-frequency front-end path of terminal switches to overlapped frequency bands.
Step 36, activates the auxiliary carrier wave in the carrier aggregation that overlapped frequency bands is corresponding, completes carrier aggregation configuration.
Step 37, however, it is determined that go out terminal and support, when described carrier aggregation configures, to swash according to the auxiliary carrier wave received
Message alive, activates auxiliary carrier wave and completes carrier aggregation configuration.
Step 38, does not carries out the configuration of the auxiliary carrier wave of carrier aggregation.
Correspondingly, the embodiment of the present invention also proposes a kind of carrier aggregation configuration device, as shown in Figure 4, and including:
Receiver module 401, for receiving the auxiliary carrier activation message completing carrier wave configuration for activating auxiliary carrier wave.
Judge module 402, for described receiver module receive for activate auxiliary carrier wave complete carrier wave configuration
Auxiliary carrier activation message time, it may be judged whether support that described carrier aggregation configures.
Determine module 403, whether be overlapping frequency spectrum coverage cell for the community that terminal is currently located.
Specifically, above-mentioned determine module 403, specifically for really the frequency point information of present access subzone being carried out
Measure；According to measurement result, determine that the community that terminal is currently located is overlapping frequency spectrum coverage cell.
AM access module 404, if determining for described judge module and not supporting that described carrier aggregation configures, and
When the described community determining that module determines that terminal is currently located is overlapping frequency spectrum coverage cell, described terminal is cut
Shift to overlapped frequency bands.
Specifically, above-mentioned AM access module 404, specifically for switching to overlap by the radio-frequency front-end path of terminal
Frequency range.
Configuration module 405, for activating the auxiliary carrier wave in the carrier aggregation that described overlapped frequency bands is corresponding, completes
Carrier aggregation configures.
Alternatively, above-mentioned configuration module 405, it is additionally operable to if it is determined that terminal supports the configuration of described carrier aggregation
Time, according to the auxiliary carrier activation message received, activate described auxiliary carrier wave and complete carrier aggregation configuration.
