Description
Technical field
The present invention relates to a kind of definite technology of re-selecting cell, relate in particular to cell selecting method and device in the definite re-selecting cell of one kind of multiple reselection modes.
Background technology
In honeycomb mobile communcations system, switch community and cell reselection is respectively the action that user terminal (UE, UserEquipment) carries out community selection while moving under connected state and disconnected state.Switch community and the object of cell reselection is in UE moving process, uses as far as possible signal quality Hao community, can obtain better service quality on the one hand, also can reduce the interference to other users on the other hand.The wireless signal strength that generally quality of community measures this community by UE is weighed.When UE leaves Yi Ge community and enters another one community, the signal of the former persistent district that it is received more and more a little less than, and the received cell signal entering is more and more stronger.In order to keep the quality of UE received signal, must be by UE by original cell switch to the signal compare Qiang community newly entering.
This gravity treatment rule based on wireless signal strength is specially, by measuring the cell parameter of current persistent district and adjacent cell, and then determine the reselecting parameters of current persistent district and adjacent cell, and determine and be applicable to the resident adjacent cell of UE according to determined reselecting parameters.Reselecting parameters can be determined in the following manner: R
s=Q
meas, s+ Qhyst
s, Rn=Q
meas, n-Qoffset, wherein, R
sthe reselecting parameters that represents the current persistent district of UE, Q
meas, srepresent the measurement level of persistent district in reuse adoption process, Qhyst
sthe sluggishness that represents current persistent district, s represents current persistent district (serving cell); Rn represents the reselecting parameters of adjacent cell, Q
meas, nbe the measurement level of adjacent cell in reuse adoption process, Qoffset is the level deviation value of adjacent cell, and n represents adjacent cell (neighbour cell).Q
meas, sand Q
meas, naccording to the method for measurement of different mobile systems, be generally the level measurement value of a kind of signal specific of definition, by UE, complete measurement.Qhyst
sand the introducing of Qoffset is in order to control better the behavior of cell reselection in the network planning, to measuring level, do an adjustment.UE sorts all reselecting parameters R values, and what make number one is best cell, and gravity treatment Dao Gai community is resident.Because the complexity of adjacent cell gravity treatment, except the radio signal quality of community, also depend on the value size of Qoffset, institute is in this way called again the residence reselecting sorting based on skew.
The frequency of distributing along with operator becomes many, and the residence reselecting based on skew sequence need to be measured the community of all carrier frequency, and calculates R value, to sort.With frequently gravity treatment, to better community, be in order to reduce interference, but during alien frequencies gravity treatment, interference problem is just so necessary.So another kind of cell reselection strategy is the residence reselecting based on frequency priority.Each frequency has priority, the high frequency of the preferential gravity treatment priority of UE, and the frequency of low priority is not first measured, until just consider that gravity treatment arrives the carrier cell that priority is identical or lower while not having higher priority frequency Shang community to select.This strategy can reduce the frequency that UE measures on the one hand, on the other hand also can be so that operator passes through the priority of regulation and control frequency, the load between control frequency.
Reselecting method based on priority, is defined as follows:
1: one higher priority frequency Shang community of condition meets Srxlev in the time of cell reselection timer duration Treselection
nonServingCell, x> Thresh
x, high.
Condition 2: when meeting Srxlev
servingCell< Thresh
serving, lowor Squal
servingCellduring < 0 condition, equal priority frequency Shang community meets Srxlev in the time of Treselection
nonServingCell, x> Thresh
x, low.
Condition 3: when meeting Srxlev
servingCell< Thresh
serving, lowor Squal
servingCellduring < 0 condition, lower priority frequency Shang community meets Srxlev in the time of Treselection
nonServingCell, x> Thresh
x, low.
If condition 1 meets, UE gravity treatment is gone on the higher frequency of priority.
If condition 2 meets, UE gravity treatment is gone on the identical frequency of priority.
If condition 3 meets, UE gravity treatment is gone on the lower frequency of priority.
For co-frequency cell, still use the cell reselection rules based on skew sequence.
Wherein Srxlev represents the level value of community selection signal, it is a normalizing value of the cell signal level that measures of UE, generally during Srxlev > 0, can think that UE can normally work in this community, if cannot meet, a little less than illustrating that this cell signal too, can not consider to select this community.Srxlev=Q

But the proposition of the new reselecting method based on priority, still can not discard the old reselecting method based on skew sequence, be because the user terminal of early version is widely used on the one hand, if the whole network is revised gravity treatment rule, the user terminal of early version cannot be supported.On the other hand, network originally is optimized by the reselecting method based on skew sequence, and operation steady in a long-term, thus network based on compatibility, consider, can support reselecting method and the reselecting method based on priority based on skew sequence simultaneously.In order to guarantee that UE can select gravity treatment rule according to the mode that can expect, during the at present communication of compatible two kinds of reselecting methods is identical, special provision following principle:
1,, for co-frequency cell, use the reselecting method based on skew sequence.
2, in all alien frequencies frequencies, when neither one alien frequencies frequency can be implemented all parameters based on priority gravity treatment, can not determine priority and corresponding gravity treatment thresholding, so for all alien-frequency districts, all use the reselecting method based on skew sequence.
3, in all different system alien frequencies rates, when the different system frequency of neither one can be implemented all parameters based on priority gravity treatment, can not determine priority and corresponding gravity treatment thresholding, so for all different system cells, all use the reselecting method based on skew sequence.
4, when in alien frequencies frequency, there are one or more than one alien frequencies frequency, while having all parameters based on priority gravity treatment, for these alien frequencies frequencies, use based on priority reselecting method so, for other alien frequencies frequency, no longer consider gravity treatment.
5, when in different system alien frequencies rate, there are one or more than one different system alien frequencies rate, while having all parameters based on priority gravity treatment, for these different system alien frequencies rates, use based on priority reselecting method so, for other different system alien frequencies rate, no longer consider gravity treatment.
By principle above, can see for same UE, based on be offset the residence reselecting of sequence and can move based on priority reselecting method simultaneously.Such as co-frequency cell gravity treatment adopts the residence reselecting based on skew sequence, alien-frequency district adopts based on priority reselecting method.Or alien-frequency district adopts, and based on being offset the residence reselecting of sequence, different system cell adopts based on priority reselecting method.The problem causing is like this if two kinds of reselecting methods move simultaneously, when if the cell reselection Target cell drawing at two kinds of reselecting methods of synchronization all meets reselection conditions, UE will can not determine which community of gravity treatment, and this obviously wishes that with operator the gravity treatment behavior of controlling UE conflicts mutually to reach the object of offered load optimization.

For making the object, technical solutions and advantages of the present invention clearer, by the following examples and with reference to accompanying drawing, the present invention is described in more detail.
Fig. 1 is the flow chart of the cell selecting method in the definite re-selecting cell of the multiple reselection modes of the present invention, and as shown in Figure 1, the cell selecting method in the definite re-selecting cell of the multiple reselection modes of the present invention comprises the following steps:
Step 101: user terminal completes to be measured the cell parameter of persistent district and adjacent cell, determines the reselecting parameters of described persistent district and adjacent cell according to measured cell parameter.
UE completes determining the reselecting parameters of current persistent district and adjacent cell in Treselection domestic demand, and according to reselecting parameters, determine the community that whether has symbol reselection conditions, while existing, select the community of this symbol reselection conditions to carry out resident, otherwise still reside in current persistent district.It should be noted that, UE need measure different cell parameters according to different adjacent cells, as described in " background technology " part, for the adjacent cell with the same frequency in current persistent district, need to adopt the cell reselection mode based on skew sequence to determine re-selecting cell, need to pass through R
s=Q
meas, s+ Qhyst
sand Rn=Q

Step 102: determining the adjacent cell meet reselection conditions according to described reselecting parameters, is while determining by least two kinds of reselection modes in the described adjacent cell that meets reselection conditions, selects one of them adjacent cell that meets reselection conditions also resident.
According to the reselecting parameters of the adjacent cell of determining in step 101, principle in conjunction with the re-selecting cell setting in current mobile communication system, determine the community that meets reselection conditions, when to meet the community of reselection conditions be a plurality of, if the reselection modes of institute's foundation is a kind of, chooses the community of reselecting parameters R maximum and carry out resident.And when when to meet the community of reselection conditions be a plurality of, if when the reselection modes of institute's foundation is two or more, need cell reselection principle according to the present invention to carry out cell reselection, gravity treatment principle of the present invention comprises:
Based on the gravity treatment of priority reselection modes, to the adjacent cell in high priority frequency, have precedence over the adjacent cell of the reselection modes gravity treatment based on skew sequence;
The adjacent cell of the reselection modes gravity treatment based on skew sequence has precedence over based on the gravity treatment of priority reselection modes to the adjacent cell in low priority frequency;
The adjacent cell of the reselection modes gravity treatment based on skew sequence has precedence over based on the gravity treatment of priority reselection modes to the adjacent cell in isopreference level frequency; Or, based on the gravity treatment of priority reselection modes, to the adjacent cell in isopreference level frequency, have precedence over the adjacent cell of the reselection modes gravity treatment based on skew sequence.
Below, by example, further illustrate technical scheme of the present invention.
Embodiment mono-:
UE resides on the community M_a1 of frequency A, by system broadcasts UE, determines frequency A upper adjacent cell M_a2, M_a3 in addition, and the adjacent cell on frequency B is M_b1, M_b2.And the priority of frequency A and B is respectively Prio
a, Prio
b, by system broadcasts, learn Prio
b> Prio
a, and Treselection and Thresh
b, highparameter etc.So should use the reselection modes based on skew sequence to determine adjacent cell reselecting parameters for frequency A Shang community, the upper use of frequency B determined reselecting parameters based on priority reselection modes.In Treselection, determine R
m_a2> R
m_a1> R
m_a3and Srxlev
m_b1> Thresh
b, high, according to the cell reselection rule of current communication system, M_a2 and M_b1 meet reselection conditions, should be the Target cells of cell reselection.But according to gravity treatment principle of the present invention, because M_a2 is the co-frequency cell of current persistent district M_a1, priority, the priority ratio M_a2 of M_b1 is high, so when meeting reselection conditions with frequency re-selecting cell and high priority community, UE selects gravity treatment to the community M_b1 of high priority simultaneously.
Embodiment bis-:
UE resides on the community M_a1 of frequency A, by broadcast, obtains frequency A upper adjacent cell M_a2, M_a3 in addition, and the adjacent cell on homologous ray frequency B is M_b1, M_b2, the adjacent cell RAT_c1 on different system frequency C, RAT_c2.And obtain the priority P rio of frequency A and B

b> Prio
a, and Treselection and Thresh
b, highetc. parameter.Because UE does not obtain the priority of different system frequency C or cell reselection thresholding (Thresh on it
c, highor Thresh
c, low), can only use the reselecting method based on skew sequence to determine adjacent cell reselecting parameters.So should use the reselecting method based on skew sequence to determine adjacent cell reselecting parameters for frequency A and different system frequency C Shang community, frequency B is upper uses the method based on priority gravity treatment to determine adjacent cell reselecting parameters.In Treselection, determine R

m_a3and Srxlev
m_b1> Thresh
b, hightime, according to the cell reselection rule of current communication system, RAT_c1 and M_b1 should be the Target cells of cell reselection.Because RAT_c1 is used the definite re-selecting cell of identical rule with the co-frequency neighbor cell of M_a1, think that the frequency priority at RAT_c1 and M_a1 place is consistent, and the priority ratio RAT_c1 of M_b1 is high, so when RAT_c1 and M_b1 meet reselection conditions, UE selects gravity treatment to the community M_b1 of high priority simultaneously.
Embodiment tri-:
UE resides on the community M_a1 of frequency A, by broadcast, obtains frequency A upper adjacent cell M_a2, M_a3 in addition, and the adjacent cell on frequency B is M_b1, M_b2, and the adjacent cell on different system frequency C is RAT_c1, RAT_c2.The priority P rio of frequency A and B

rAT_c1> R
m_a1> R
rAT_c2> R
m_a3> R
m_a2and Srxlev
m_a1< Thresh
serving, 1owand Srxlev
m_b1> Thresh
b, low, according to the cell reselection rule of current communication system, RAT_c1 and M_b1 should be the Target cells of cell reselection.The gravity treatment of the agreement of here take regulation based on skew sequence has precedence over frequency priority and equates that in situation, the gravity treatment based on frequency priority is example, and selecting RAT_c1 is gravity treatment Target cell.Only having M_a1 under the reselecting method based on skew sequence be best cell, and under the method under the condition without gravity treatment, UE just can select the Target cell under the reselecting method based on priority of equal priority frequency, i.e. M_b1.In the present embodiment, also can stipulate that the gravity treatment based on frequency priority has precedence over the gravity treatment based on skew sequence in the equal situation of frequency priority, now will choose M_b1.
Embodiment tetra-:
UE resides on the community M_a1 of frequency A, by broadcast, obtains frequency A upper adjacent cell M_a2, M_a3 in addition, and the adjacent cell on frequency B is M_b1, M_b2, and the adjacent cell on different system frequency C is RAT_c1, RAT_c2.The priority P rio of frequency A and B
a, Prio
bpass be Prio
b< Prio
a, by broadcast, also obtain Treselection, Thresh
serving, lowand Thresh
b, lowetc. parameter.Because UE does not obtain the priority of different system frequency C or cell reselection thresholding (Thresh on it
c, highor Thresh
c, low), so should use the reselecting method based on skew sequence to determine reselecting parameters for frequency A and different system frequency C Shang community, frequency B is upper uses the reselecting method based on priority to determine reselecting parameters.In Treselection, determine R
rAT_c1> R
m_a1> R
rAT_c2> R
m_a3> R
m_a2, Srxlev
m_a1< Thresh
serving, lowand Srxlev
m_b1> Thresh
b, low, according to the cell reselection rule of current communication system, RAT_c1 and M_b1 should be the Target cells of cell reselection.Because Prio
b< Prio
a, for the definite cell reselection parameters of reselecting method of using based on skew sequence, the frequency priority of carrier frequency A and C is consistent, has precedence over frequency B, and therefore, selecting RAT_c1 is here the Target cell of gravity treatment.
