Embodiment 2
The embodiment of the present invention provides a kind of method of user equipment access carrier converging network, applied to as shown in Figure 1
Carrier wave converging network, it is assumed that the cell in eNB coverage area is first community, which is main plot, eNB coverage area
The cell of interior micro-base station is second community, which is secondary cell, as shown in figure 3, the method includes：
Step 201, user equipment 1 send registration request to eNB.
User equipment 1 enters the coverage area of first community and the region of second community overlapped coverage, due to described
The priority of first community is higher than the priority of the second community, and user equipment sends registration request to eNB, and the registration is asked
The cell id including first community is sought, for requesting eNB to be registered to first community, the first community is the cell of TDD frequency range,
The second community is the cell of FDD frequency range.It should be noted that eNB can be managed collectively the cell and the eNB of the eNB
Coverage area in micro-base station cell.
Step 202, eNB send registration reply message to user equipment 1.
User equipment 1 is registered to first community according to registration reply message.
Step 203, user equipment 1 send first message to eNB.
The first message includes the ability of the user equipment 1, and the ability of the user equipment 1 is used to indicate the use
Family equipment 1 supports Frequency Division Duplex FDD frequency range and Time Division Duplex TDD frequency range.
Step 204, eNB judge that the load value of second community is less than or equal to threshold value.
After eNB receives the ability of the user equipment 1 of the transmission of user equipment 1, judge second locating for the user equipment 1
Whether the load value of cell is less than or equal to threshold value.In general, Physical Resource Block (full name in English can be passed through：physical
Resource block, English abbreviation：PRB occupancy α) judges the size of load value, and the occupancy α of PRB gets over heavy load
Value is bigger, and the load of small area carrier is bigger, and similarly, the threshold value of load value can be the occupancy threshold value α of PRBth.Tool
Body, eNB may determine that whether the occupancy α of the PRB of second community is less than or equal to the occupancy threshold value α of PRBth, wherein
The occupancy threshold value of PRB can be set by operator oneself, and operator can be come with the occupancy situation of the history PRB of reference cell
Setting, in general, the occupancy threshold value α of PRBthIt can be set to 70%.It should be noted that when judging the load value of cell
The negative of cell can be judged together with the occupancy of PRB with reference to the type of service that user equipment uses, or with reference to type of service
Load value.
When the load value of second community is less than or equal to threshold value, step 205 is executed.When the load value of second community is less than
When equal to threshold value, illustrate that the cell load of FDD frequency range is lower, even if user equipment is switched in the cell of FDD frequency range,
Too big burden will not be caused to the cell of FDD frequency range.
When the load value of second community is less than or equal to threshold value, step 206 is executed.
Step 205, eNB send the first wireless resource control connection reconfiguration message to user equipment 1.
First wireless resource control connection reconfiguration message (Radio Resource Control Connection
It Reconfiguration) include the switching instruction, the switching instruction is used to indicate the user equipment 1 and is switched to second
Cell.
Further, the first wireless resource control connection reconfiguration message further includes switch reasons field (handover
Cause), the switch reasons field is the field newly increased in the first wireless resource control connection reconfiguration message, the switching
Cause field is located at mobile control information (the Mobility Control of the first wireless resource control connection reconfiguration message
Info) in field.When switch reasons field is set as " 1 ", instruction return back to carrier wave polymerization state；When switch reasons field is set
When being set to " 0 ", other switchings are indicated, that is, be not required to switching caused by carrying out carrier wave polymerization, but as caused by other reasons
Switching.
Step 206, eNB send the instruction for continuing to be resident first community to user equipment 1.
Step 207, user equipment 1 are switched to second community.
The detailed process that user equipment 1 is switched to second community can be no longer superfluous herein with reference to the switching flow in LTE
It states.
Step 208, eNB send the second wireless resource control connection reconfiguration message to user equipment 1.
It is small that the second wireless resource control connection reconfiguration message is used to indicate described in the user device configuration first
Area.
Step 209, user equipment 1 are according to the second wireless resource control connection reconfiguration message arrangement first community.
User equipment 1 sends second according to the second wireless resource control connection reconfiguration message arrangement first community, to eNB
Wireless resource control connection reconfiguration completes message, and eNB activates first community.
Compared with the existing technology, when user equipment is resident in the cell of TDD frequency range, when using TDD as main carrier, nothing
Method effectively utilizes Internet resources to improve transmission rate.The present invention according to the ability of the user equipment of user equipment to report,
Indicate that the user equipment supports Frequency Division Duplex FDD frequency range and Time Division Duplex TDD frequency range, and where judging the user equipment
When the load value of the cell of FDD frequency range is less than or equal to threshold value, switching instruction is sent to the user equipment, indicates the user
Equipment is switched to the cell of FDD frequency range, then sends configuration message to the user equipment, indicates the user device configuration TDD
The cell of frequency range, to make user equipment be in carrier wave polymerization state, so that TDD carrier wave can be used for user equipment and FDD is carried
Wave comes together to transmit data, can effectively utilize Internet resources to improve transmission rate.
Particularly, if user equipment is in the coverage area of the cell of eNB and at least two micro-base station
In the coverage area of cell, user equipment first measures the user equipment to the signal quality of each micro-base station, selection signal quality
The cell of best one micro-base station is registered.Then step 203 is executed again to step 209.
