Wherein, since first community is the lower cell of the first communication system covering, each of under being covered to the first communication system
Cell carries out the mode and principle all same of Idle state gravity treatment, therefore the embodiment of the present invention is only illustrated by taking first community as an example,
And do not have any indicative meaning, it is similarly, logical to second since the second community is the lower cell of the second communication system covering
The lower each cell of letter system covering carries out the mode and principle all same of cell load equilibrium again, thus the embodiment of the present invention only with
It is illustrated for second community.
Step S101 can be accomplished by the following way：
In LTE network the cell broadcast messages of serving network node eNB MIB (Master Information Block,
Master Information Block) in carry cell load information, pass through PBCH (Physical broadcast channel, physical broadcast letter
Road) it is broadcasted.After UE in this way receives the load information of Cell Broadcast CB, can according to the signal strength of cell and load condition into
Whether row comprehensive descision wants gravity treatment selection cell to be also to continue with and resides in the first community.
If the preset signal strength in broadcasting the message described in the signal intensity ratio of the first community is low, UE measures adjacent area
Signal quality, and choose according to the cell of highest priority in the broadcast message that neighboring area signal intensity is highest is stayed
It stays.
After UE to being in Idle state in first community carries out load balancing, since UE may be moved or can be continually
Initiating business request and business release, for example, can also do the request of RRC connections in the short time of RRC connections upon discharge, at this moment
The mobile subscriber's quantity in release state is obtained by wireless side, if the mobile subscriber's quantity in release state is more than first
The load balance thresholding of cell then carries out cell reselection to balance the first community to the mobile subscriber in release state
Load number, since the mobile subscriber in release state come the signaling that sends by carrying out gravity treatment according to receiving base station, for example,
Base station to UE by sending RRC release message connection release message, in the connection release message
By idleModeMobilityControlInfo cells carry pilot frequency point priority, UE after returning to Idle state pattern
Gravity treatment is carried out using the dedicated priority in idleModeMobilityControlInfo cells in the T320 times.T320 time-out
Afterwards, restore to carry out gravity treatment using the priority of SIB (system information block, system information block) broadcast.
For example, shown in table 1, if the cell (priority is set as 6) that mobile subscriber accesses under the TD-LTE network coverages is initiated
Business, the frequency point priority of the adjacent cell of FDD-LTE networks is 5 before load is balanced again, then enter load it is balanced again when,
It is excellent by idleModeMobilityControlInfo cells carrying FDD cells in RRC connection release message
First grade is 7, then after UE receives the priority of the cell under the FDD-LTE network coverages, since present FDD-LTE networks cover
Native region priority under lid is temporarily higher than TD cells, can measure the RSRP values of the cell under the adjacent cell FDD-LTE network coverages, if
The RSRP values of the FDD adjacent cells are more than pre-determined threshold, then mobile subscriber triggers small under gravity treatment to the FDD-LTE network coverages
Area.
| Parameter name | Parameter declaration | FDD-LTE | TD-LTE |
| CellReselPriority | Serving cell priority | 6 | 6 |
| CellReselPriority | The priority of alien frequencies | 7 | 5 |
| MlbFreqPriority | Load balancing frequency point priority | 5 | 7 |
Illustratively, for first movement user, first movement user is that any one movement is used in the first community
Family, due to carrying out the mode and principle all same of cell reselection to each mobile subscriber of the first community, therefore the present invention is implemented
Example is only illustrated by taking first movement user as an example, and does not have any indicative meaning.
As shown in Figure 2:First movement user into the first community sends reselecting parameters thresholding, so that described first
Mobile subscriber carries out cell reselection, including：
S1011, the priority and signal quality for obtaining the first community that the first movement user is currently resident；
As it is desirable that absorbing business, FDD-LTE networks/TD-LTE network interoperabilities using TD-LTE networks in hot spot region
Deployment strategy should totally use TD-LTE networks for high gravity treatment priority, and FDD-LTE networks are low gravity treatment priority, same to site
TD-LTE network absorbent core area data services cover preferably basis FDD-LTE networks and absorb outer circle business, i.e. real in this way
Show business and shared and in turn ensures the reliable of switching.
First base station obtains the serving cell that the first movement user is resident from the equipment of the core network, judges institute
The resident serving cell is the cell of the FDD-LTE network coverages or the cell of the TD-LTE network coverages, to according to pre-
If criterion, i.e., high gravity treatment priority, FDD-LTE networks be low gravity treatment priority, can know that first movement user is resident
Serving cell whether be high priority cell.It can be according to drive test data or MR (Measurement Report, measurement report
Accuse) data acquisition first base station covering each cell (RSRP (and Reference Signal Receiving Power, ginseng
Examine signal reception power), using the practical dividing value (CDF statistical values) for occupying RSRP of mobile subscriber as high gravity treatment priority cell
With the gravity treatment boundary of low gravity treatment priority cell, the mobile subscriber that will be above RSRP dividing values resides in high gravity treatment priority cell.
S1012, the priority for the first community being currently resident as the first movement user are preferential higher than neighboring community
When grade, in reselection time, the first reselecting parameters thresholding, the first reselecting parameters thresholding are sent to the first movement user
More than or equal to the signal quality of the first community, and less than the signal quality of the neighboring community；
S1013, the first community being currently resident as the first movement user priority less than the neighboring community
When priority, in reselection time, the second reselecting parameters thresholding, second reselecting parameters are sent to the first movement user
Thresholding is less than the signal quality of the neighboring community.
Wherein, in order to ensure resided under Idle state pattern same sector by FDD-LTE networks and TD-LTE nets
Network covering cell quantity and ratio be it is equal,
Due in order to ensure make in second community in release state mobile subscriber behind re-selecting cell, it is possible to reduce
The load of the first community, therefore need to need to carry out according to the determination of the default load balancing releasing ratio of the second community small
The mobile subscriber's quantity of area's gravity treatment, if for example, the default load balancing releasing ratio of second community is 50%, first base station obtains
All mobile subscriber's quantities in the second community are taken, and are obtained in the second community in release state from wireless net side
Mobile subscriber's quantity, if the load proportion (mobile subscriber's quantity/all mobile subscriber's quantities of release state) × 100% >=pre-
If load balancing releasing ratio, then need are obtained from all mobile subscriber's quantities according to the default load balancing releasing ratio
Carry out the mobile subscriber of cell reselection.
Wherein, for realize step S103 mode there are many, the embodiment of the present invention to this without limit, be only example
Property, S103 can be accomplished by the following way：
S1031, first message is sent to the mobile subscriber of the balanced releasing ratio that overloads, in the first message
Include the frequency point priority of Target cell, and the frequency point priority of the second community is preferential less than the frequency point of the Target cell
Grade.
Wherein, the first message refers to that base station is disappeared by sending RRC release message connection release to UE
It ceases, it is excellent by idleModeMobilityControlInfo cells carrying pilot frequency point in the connection release message
First grade, UE is after returning to Idle state pattern using in idleModeMobilityControlInfo cells within the T320 times
Dedicated priority carries out gravity treatment.After T320 time-out, restore to use SIB (system information block, system information
Block) broadcast priority carry out gravity treatment.
In order to ensure signal strength is preferable in newly resident cell into the mobile subscriber of cell reselection, and avoid the shifting
Overload will not be occurred because of access mobile subscriber by employing the cell that family is newly resident, described before the step S103
Method further includes：
S104, the information on load for obtaining the cell adjacent with the second community；Wherein, the information on load includes described
Handover success rate, hardware state, adjacent area load；
If there are the information on load of at least one cell to meet default want in S105, the cell adjacent with the second community
