In order to avoid the above problem, a kind of existing network deployment strategy is：Two cells for throwing the net network are not configured to mutually
Adjacent area avoids UE (terminal) from being switched between two kinds of cells.But the cell of IDLE (idle state) UE is selected, still
And without good method of controlling, many non-high ferro passenger UE is caused to reside in high speed overlay network and initiate business.
Another network deployment strategy is：Two cells for throwing the net network are mutually arranged for adjacent area, but for the cell of IDLE UE
Selection, also without method of controlling well, after only non-high ferro passenger UE enters connection status, network can trigger by UE from
High speed overlay network cell is switched to generic network cell.
In conclusion existing non-passenger terminal still may reside within when being in idle condition under high speed overlay network,
There are no effective means to be moved out high speed overlay network.

The case where.
In above-mentioned specific implementation mode, S criterion and R criterion are abided by when carrying out cell reselection.
In cell selection procedure, terminal needs measure the cell that will be selected, to carry out channel quality assessment,
Judge whether it meets resident standard.And the measuring criterion of cell selection is referred to as S criterion, when the channel quality of some cell
After meeting S criterion, so that it may to be selected as persistent district.The particular content of S criterion is as follows：
Srxlev>0；
Srxlev=Qrxlevmeas-(Qrxlevmin+Qrxlevminoffset)-Pcompensation
Wherein, Qrxlevmeas is the Reference Signal Received Power RSRP of candidate cell；Qrxlevmin and
Qrxlevminoffset is the resident minimum reception level of the cell of configuration, and Pcompensation is to take UE uplink maximums can
The transmission power PEMAX used subtracts maximum value (the i.e. MAX among the difference and 0 of UE maximum radio frequency output powers PUMAX
(PEMAX-PUMAX, 0)) unit dB.
Terminal obtains the Qrxlevmeas values of cell when carrying out cell selection, by measuring, and is believed by the system of cell
Breath and self-ability grade obtain the other parameters in S criterion formulas, and Srxlex is calculated, is then compared with 0, if
Srxlex>0, then terminal think the cell meet cell selection channel quality requirement, persistent district can be selected as.Such as
It is broadcasted in the system information of the fruit cell to allow to be resident, then terminal will select to be resident in this cell, into idle shape
State.
When terminal is in idle condition, it needs lasting carry out cell reselection, to reside in priority higher/channel
The cell of better quality.Network can achieve the purpose that control terminal is resident by the priority of setting different frequent points, meanwhile,
The cell that terminal will select channel quality best on some frequency point, preferably to provide service for it.In this manner it is possible to real
Now to the mobile management of terminal idle state.
Cell reselection can be divided into co-frequency cell gravity treatment and alien-frequency district gravity treatment, for co-frequency cell gravity treatment, main purpose
It is to solve the problems, such as wireless coverage, and for alien-frequency district gravity treatment, both can be used for solving the problems, such as wireless coverage, can be used for bearing
It carries balanced.
(A) flow of co-frequency cell gravity treatment is as follows：
1, pass through parameter in the parameter S of serving cell (computational methods of S values are consistent when being selected with cell) and system broadcasts
Sintrasearch comparisons decide whether to start common frequency measurement；
2, R criterion sequences are carried out according to quality height to candidate cell, selects optimum subdistrict；
3, determine whether optimum subdistrict is suitable cell according to suitable cell criterion, suitable cell in this way then can conduct
The Target cell of gravity treatment.
R criterion are expressed as follows：
Rs=Qmeas_s+Qhysts
Rn=Qmeas_n-Qoffsets_n
Wherein, Qmeas_s is serving cell received signal quality measured value；Qmeas_n is adjacent cell received signal quality
Measured value；Qhysts is that cell reselection is sluggish；Qoffsets_n is the difference of two cell received signal quality requirements.
The criterion of cell reselection is：If the Rn and Rs that continuously measure interior when detecting can keep Rn>Rs,
Frequency point identical for priority, the sequencer procedure in gravity treatment is consistent with co-frequency cell gravity treatment, that is, uses R accurate
Then.
(B) flow of alien-frequency district gravity treatment is as follows：
In the reuse adoption process of alien-frequency district, network can be by being arranged rational priority parameters, to realize different frequent points
Load balancing purpose.The priority pointed out for network is higher than the current frequency point for being resident frequency point, and UE is always executed to these
The measurement of high priority frequency point；
For the cell reselection of high priority frequency, carried out after meeting the following conditions：
1, the S values of high priority frequency cells are more than pre-determined threshold, and the duration is more than Treselection；
2, the time of the resident former cells of UE is more than 1s.
If there are multiple cells to meet above-mentioned standard on highest priority, select optimal small in highest priority frequency
Area.
For the cell reselection of low priority frequency, carried out after meeting the following conditions：
1, the cell of no high priority frequency meets reselection requirement；
2, meet reselection requirement without the cell of All factors being equal, preference will be give to grade frequency；
3, the S values of serving cell are less than preset thresholding, and the S values of low priority frequency point cell are more than pre-determined threshold, and
Duration is more than Treselection；
4, the time of the resident former cells of UE is more than 1s.
The residence reselecting of the present embodiment is described further with reference to specific application scenarios：
