Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and examples,
Technical solution of the present invention is described in detail.
It provides a kind of with covering alien-frequency district generation method in the embodiment of the present application, is applied to that terminal quantity is big, business is fast
In the small networking of rate；By being the small bandwidth of multiple alien frequencies by big bandwidth partition, establishes multitiered network overlapping and cover same cell, come
Expand power system capacity, meets trade Special Network to the needs of large capacity.
In the following, being described in detail in the embodiment of the present application in conjunction with attached drawing with covering alien-frequency district generating process.
It is in the embodiment of the present application with covering alien-frequency district product process schematic diagram referring to Fig. 1, Fig. 1.Specific steps are as follows:
Step 101, system bandwidth is divided into n alien frequencies bandwidth by base station.
Step 102, which generates an alien-frequency district for each alien frequencies bandwidth；Wherein, raw for n alien frequencies bandwidth
At n alien-frequency district be with covering alien-frequency district.
In this step when producing n alien-frequency district, pass through cell splitting technology；Or, the mode for increasing RRU establishes n
With covering alien-frequency district.
Referring to fig. 2, Fig. 2 is that n are generated by cell splitting technology with covering alien-frequency district schematic diagram.Still make in Fig. 2
With a RRU come networking, a RRU corresponds to n cell.
Existing realization is pressed in Fig. 2, i.e., assumes that power system capacity is A in the single layer cell that frequency is f, then passes through the application's
With in covering alien-frequency district generation scheme, the power system capacity of n cell is n × A.
Referring to Fig. 3, Fig. 3 is that n are generated by way of increasing RRU with covering alien-frequency district.Increase n-1 in such as 3
RRU makes each RRU correspond to multiple cells.
Existing realization is pressed in Fig. 3, i.e., assumes that power system capacity is A in the single layer cell that frequency is f, then passes through the application's
With in covering alien-frequency district generation scheme, the power system capacity of n cell is n × A.
Big bandwidth cell is divided into the small bandwidth cell of multiple alien frequencies in the present embodiment, is overlapped overwrite job region to solve
The limited problem of single layer cell capacity.
After one cell is divided into multiple alien-frequency districts with covering, the number of terminals accessed in each cell has more to be had less,
In order to coordinate to access each cell terminal number equilibrium, the application also proposes that dynamic adjusts the scheme of each cell load.
Base station is that each cell configures identical initial priority, i.e., identical when the frequency point priority of each cell is initial
, the chance of at this moment terminal access cell is random.
After base station works normally, periodically it can be counted using T as the period and be in wireless heterogeneous networks (Radio in each cell
Resource Control, RRC) connected state number of terminals.
With reference to the accompanying drawing, detailed description the embodiment of the present application medium and small interval load sharing realizes process.
Embodiment one
Referring to fig. 4, Fig. 4 is cell load sharing flow diagram in the embodiment of the present application one.Specific steps are as follows:
Step 401, for any period, base station determines the most cell of the number of terminals in RRC connected state and least
The number of terminals difference of minizone.
Step 402, base station determines whether the number of terminals difference is greater than first threshold, if so, executing step 403；It is no
Then, step 404 is executed.
Step 403, which is adjusted to the frequency point priority of the least cell of present terminal number to be higher than initial priority；
And broadcasted in the cell by system information update message, while being carried in RRC connection release message, terminate this process.
Step 404, which waits next period, and the end that RRC link state is handled in each cell is counted in next period
Hold number.
Embodiment two
It is cell load sharing flow diagram in the embodiment of the present application two referring to Fig. 5, Fig. 5.Specific steps are as follows:

The number of terminals difference of minizone.
Step 502, base station determines whether the number of terminals difference is greater than first threshold, if so, executing step 503；It is no
Then, step 508 is executed.
Step 503, which determines whether current period is m-th of continuous period for adjusting subdistrict frequency point priority, such as
Fruit is to execute step 504；Otherwise, step 506 is executed.
If the least cell of present terminal number has multiple, it can choose one of cell and carry out frequency point priority tune
It is whole, frequency point priority adjustment can also be carried out to the least cell of all number of terminals, i.e., all reduce frequency point priority, and adjust
Frequency point priority afterwards is low.
Determine whether current period is m-th of continuous period for adjusting subdistrict frequency point priority, i.e. determination is worked as in this step
Whether the preceding m-1 continuous cycles in preceding period have all carried out the adjustment of subdistrict frequency point priority, i.e., when subdistrict frequency point priority adjusts
Number when reaching certain number, just consider whether to carry out the cell of switching terminal access by force.
Step 504, which determines the end for being converted into RRC connected state in the previous cycle of current period by RRC Idle state
Whether end number is greater than second threshold, if so, executing step 505；Otherwise, step 506 is executed.
Step 505, which carries out terminal switching, and the terminal for making each cell load be in RRC connected state reaches load
Weighing apparatus；And be not the frequency point priority of all cells of initial priority by frequency point priority, it is adjusted to initial priority, executes step
Rapid 507.

It changes.
The specific rules of cell switching are not construed as limiting in the application specific embodiment, each cell load can be made to be in
The terminal of RRC connected state reaches load balancing, reaches the most cell of number of terminals in each cell in RRC connected state in other words
It is not more than the effect of first threshold with the number of terminals difference of least minizone.
Step 506, which is adjusted to the frequency point priority of the least cell of present terminal number to be higher than initial priority.
When each cell access number of terminals have already passed through adjustment reach this application claims load balancing when, need to restore each
The initial priority of cell, so that chance that subsequent terminal accesses each cell is identical.
Step 507, the frequency point priority adjusted which will adjust the cell of priority is updated by system information
Message is broadcasted in the cell, while being carried in RRC connection release message, this process is terminated.
The terminal for not accessing cell is received according to new by carrying priority adjusted in system information update message
To frequency point priority accessed, so as to the big cell of access frequency point priority, i.e. the not small cell of access frequency point priority.
RRC Connection Release (Connection Release) message carries frequency point priority, for having accessed in cell
Terminal after terminal receives this message, can be subject to this, though the priority change in system information, and with connection
Subject to the frequency point priority carried in release message；Until it again initiate access or T320 time-out, or re-execute PLMN choosing
When selecting, the frequency point priority be subject in the system information update message received.
Step 508, which waits next period, and the end that RRC link state is handled in each cell is counted in next period
Hold number.
This step terminates the processing for current period, into the processing in next period.
Terminal receives system information update message, obtains the relevant information for accessing each cell, such as subdistrict frequency point priority；
When for accessing each cell, determine which cell accessed.
When capacity difference reaches threshold value in minizone in the present embodiment, capacity adjusting scheme is provided, supports capacity between multiple cell
