Description

CELL RESELECTION METHOD, BASE STATION, TERMINAL, AND SYSTEM
Residence reselecting, base station, terminal and systems technology field
The present invention relates to wireless communication technology field, in particular to residence reselecting, base station, terminal and system.Background technology
In mobile radio system, the state of terminal is divided into connection status and idle condition.In an idle state, terminal needs to receive broadcast message from base station, receives service.Due to the mobility of terminal, in order to which it can be properly received the broadcast message of base station transmission, terminal needs to carry out cell reselection in time, and selection can be supplied to the cell of oneself correct broadcast message.If selected cell disclosure satisfy that cell re-selection conditions, terminal just resides in this cell, until gravity treatment to another cell.
When mobile terminal is moved in a network, the motion state of oneself can be estimated under connection or idle condition.In an idle state, terminal can add up the efficient cell reselection frequency of oneself within the period of configuration, then compare count results with the threshold value of system configuration, obtain the motion state of oneself.Wherein, motion state can be divided into three classifications：At a high speed, middling speed or common.In connected state, terminal can add up the effective switching times of oneself within the period of configuration, then compare count results with the threshold value of system configuration, obtain the motion state of oneself.Wherein, motion state can also be divided into three classifications：At a high speed, middling speed or common.
In existing GSM, with developing rapidly for business, original macro base station service ability is limited, and with the change of the landforms such as building, can there is some covering blind spots.Therefore, operator can be in hot spot region or covering blind spot region arrangement cell, the service ability and coverage of lifting system.In general, the radius of cell is smaller（50 meters or so）, its base station is arranged net more flexible with respect to macro cell base station more cylinder list.The coverage of cell can be within the coverage of macro base station（It is mainly used to increase power system capacity）Or outside the coverage of macro base station（It is mainly used to enhancing covering）.Frequency where cell can be independently of macro base station frequency or with macro base station shared frequency.As shown in Fig. 1, it is assumed that all macro base stations are corresponding grand Cell 102 constitutes macrocell layer 1020, and all cells 104 constitute small cell layer 1040.Because the radius of cell 104 is smaller, if some terminal for being in idle condition exists concurrently with the local high-speed motion that macrocell layer 1020 and small cell layer 1040 are covered, if terminal selection receives the service of small cell layer 1040, reside in small cell layer 1040, it is accomplished by frequently performing cell reselection, and it is related to the steps such as cell searching, measurement, gravity treatment judgement in reuse adoption process, and need to obtain serving cell system information etc. after the completion of reuse adoption process, these can all increase the power consumption of terminal.Therefore, this frequently cell reselection should be avoided as far as possible, that is to say, that high-speed terminal should reside in macrocell layer 1020 as far as possible.Meanwhile, similar, if high-speed terminal is in connection status, in order to avoid frequent switching, it should also try one's best in the receiving service of macrocell layer 1020.And when terminal is changed by idle condition to connection status, the serving cell that it is first had under same idle condition is communicated, receive its service.If high-speed terminal resides in macrocell layer 1020 in an idle state, be converted to directly can just be communicated under connection status in macrocell layer 1020.And if high-speed terminal resides in small cell layer 1040 in an idle state, when being converted to connection status, communicated first in small cell layer 1040, macrocell layer 1020 is then also switched to, unnecessary handover overhead is added.

In order to be more clearly understood that the above objects, features and advantages of the present invention, the present invention is further described in detail with reference to the accompanying drawings and detailed description.It should be noted that in the case where not conflicting, the feature in embodiments herein and embodiment can be mutually combined.
Many details are elaborated in the following description to facilitate a thorough understanding of the present invention, still, the present invention can also be different from other modes described here to implement using other, therefore, and the present invention is not limited to the limitation of following public specific embodiment.
Embodiment one
Fig. 2 shows that terminal according to an embodiment of the invention carries out the schematic diagram of cell reselection according to cell reselection parameters.
As shown in Figure 2, in the technical scheme that terminal according to an embodiment of the invention carries out cell reselection according to cell reselection parameters, the cell reselection parameters of the terminal corresponding to different translational speeds are generated by base station 202, terminal is such as divided into by high-speed terminal, middling speed terminal and low speed terminal according to translational speed, then for same cell reselection parameters, base station 202 will generate corresponding high-speed terminal parameter, middling speed terminal parameter and/or low speed terminal parameter.And for terminal, it is assumed that terminal 204A is high-speed terminal, then terminal 204A is when receiving high-speed terminal parameter, middling speed terminal parameter and low speed terminal parameter, cell reselection operation can be carried out from high-speed terminal parameter, and middling speed terminal parameter and low speed terminal parameter can not then be responded；It is assumed that terminal 204B is low speed terminal, then terminal 204B can carry out cell reselection operation from low speed terminal parameter, and high-speed terminal parameter and middling speed terminal parameter can not then be responded.Similarly, middling speed terminal parameter can then be selected for middling speed terminal（Not shown in figure）.
Certainly, base station 202 is remained on as needed can generate the generic cell reselecting parameters for not differentiating between motion state of terminal（Cell reselection parameters namely of the prior art, not shown in figure）, can not be judged that the terminal of motion state is used；Though motion state can also have been judged base station 202 do not generate the corresponding cell reselection parameters of its motion state terminal use, such as when base station 202 only generates low speed terminal parameter, it is assumed that terminal 204A is high-speed terminal, then cell reselection can be performed using above-mentioned generic cell reselecting parameters.
By the above-mentioned means, then base station 202 can control the cell reselection result of the terminal of different translational speeds, such as, for high-speed terminal, it can be controlled to reselect to macrocell as much as possible, it is to avoid when weight When choosing is to cell, unnecessary frequent gravity treatment is carried out in an idle state, while also avoiding the unnecessary switching for needing to carry out upon entering the connected state, causes to increase the unnecessary power dissipation overhead of terminal.Certainly, base station 202 can carry out the control of cell reselection using similar mode to the terminal of any translational speed, but base station 202 it is not absolutely required to all be controlled the terminal of all translational speeds, such as when base station 202 is only controlled to high-speed terminal, it then can only generate corresponding high-speed terminal parameter, and to other motion states or the terminal without decision state still uses generic cell reselecting parameters.Or, base station 202 can be generated while the parameter of the terminal corresponding to a variety of translational speeds, such as simultaneously corresponding to high-speed terminal and the parameter of middling speed terminal, then high-speed terminal and middling speed terminal can be responded to the parameter, the cell reselection result of these terminals is controlled so as to realizing, and to other motion states or the terminal without decision state is still using generic cell reselecting parameters.
Below in conjunction with Fig. 3 to Fig. 7, respectively from base station 202 and terminal（Include terminal 204A, terminal 204B and other translational speeds terminal）Both sides, with reference to the type and concrete details of cell reselection parameters, the embodiment shown in Fig. 2 is described in more detail.
As shown in figure 3, for base station, it generates cell reselection parameters so that the flow that terminal carries out cell reselection includes：
Step 302, generation corresponds to the cell reselection parameters of different translational speeds, and to cell reselection parameters described in terminal notification, to utilize the cell reselection parameters corresponding to itself translational speed to carry out cell reselection by the terminal；Wherein, the cell reselection parameters include at least one of or its combination：Forbid information, cell reselection priority set, cell reselection frequency set, cell reselection time set, reselection criterion thresholding value set.In the technical scheme, by using any one or more in cell reselection parameters proposed by the present invention, and the cell reselection parameters for being directed to different translational speeds are generated, so as to enable the terminals to realize cell reselection operation using the cell reselection parameters matched with the translational speed of itself.Because the translational speed of terminal matches with cell reselection parameters, thus the terminal gravity treatment of different translational speeds to cell type also likely to be present difference, such as so that high-speed terminal reselects to macrocell as far as possible, unnecessary switching is performed so as to reduce the reselection frequency of terminal and avoid enter into after connection status, the power dissipation overhead of terminal is reduced.
For the above-mentioned five kinds of cell reselection parameters proposed in the present invention, it will be described in detail respectively below： (one）Forbid information
Cell needs to meet after certain condition, could be by terminal gravity treatment, and the i.e. cell of one of its condition can not be confined.Specifically, such as, it is impossible to be forbidden or by Operator reserves.Base station can broadcast the limitation parameter of correlation in system message, such as " forbid " parameter（Cell Barred) and " Operator reserves " parameter (cell Reserved For Operator Use).With the relevant parameter of " limitation " in terminal read system message, if these parameters show that current base station is to be limited gravity treatment, such as it is prohibited or by Operator reserves, terminal is unable to gravity treatment to current area.
Therefore, base station can forbid the terminal of specific motion state to be resident this cell by broadcasting special " forbidding " information.Such as, if it is resident herein that current area is not intended to high-speed terminal, base station can be broadcasted forbids information for high speed mobile terminal, so, high-speed terminal read this for high-speed terminal forbid would not reside in current area after information, even and if other motion states or reading this message without the terminal for judging motion state and being also unaffected.
Specifically, in lte-a system, base station can be added in SIB1 broadcast messages forbids information for high-speed terminal（Cell Barred High ) .This forbids information just for high-speed terminal, is not worked to other motion states or without the terminal for judging motion state.Certainly, for high-speed terminal, if forbidding residing in current area will be with reference to Cell Barred High and/or other restricted information.
Similar, if current area is not intended to middling speed or low speed terminal resides in current area, " forbidding " information for being directed to middling speed or low speed terminal can also be broadcasted.So middling speed or low speed terminal may after reading for middling speed or " forbidding " information of low speed terminal（Because may also need to refer to other information）Current area will not be resided in, even and if other motion states or reading this without the terminal for judging motion state and " forbidding " information not also to be affected.Its specific notification procedure is with notifying high-speed terminal to forbid the process of information similar.
(two）Cell reselection priority set
Base station can provide the terminal with the list of frequency for carrying out cell reselection, and for each frequency, can provide its corresponding gravity treatment priority (cell Reselection Priority) terminal can search for neighbor cell in the frequency of offer（Including the cell on the neighbor cell in high priority frequency, All factors being equal, preference will be give to level frequency or co-frequency cell, low priority frequency）, and judge whether to measure and using corresponding cell reselection criterion according to the priority of its frequency.Terminal can be from broadcast message or specific messages List of frequency and its priority are obtained, its priority can also be inferred to according to some pre-set criterias, wherein, the priority in broadcast message can send all terminals into cell, and the priority in specific messages then can be only sent to specific terminal（And this priority is only effective in certain period of time）.
Terminal according to list of frequency to the neighbor cell searched when measuring, if current serving cell signal quality is good enough（Meet certain condition）, neighbor cell in measurement All factors being equal, preference will be give to level or low priority frequency can not be gone to.But under any circumstance, terminal has to measure the neighbor cell in the high priority frequency searched, it therefore, it can the gravity treatment priority by specifying cell in cell reselection priority set, it is possible to the cell reselection result of control terminal.
Specifically, to same frequency, base station can be to the different gravity treatment priority of the terminal notification in different mobile status.Macrocell layer in such as current system uses frequency F1, and small cell layer uses frequency F2, in order to reach the purpose for allowing high-speed terminal to reside in macrocell layer, can be arranged such that：For high-speed terminal, F1 gravity treatment priority is higher than F2 gravity treatment priority（Such as, the numeral of priority is bigger, and rank is higher）；Simultaneously for other motion states or without for the terminal for judging motion state, F1 gravity treatment priority is less than F2 gravity treatment priority.So, high-speed terminal just more they tends to gravity treatment and resides in macrocell layer, and other sportswear states or tends to gravity treatment without the terminal for judging motion state and reside in small cell layer.
During specific notice, this notification procedure can be realized by unicast and/or broadcast message,, can be in RRC Connection Release unicast messages such as in lte-a system, and/or SIB3 (is used for the reselecting parameters for broadcasting co-frequency cell）(it is used for the reselecting parameters for broadcasting alien-frequency district with SIB5）In broadcast message, notify some frequency of all terminals corresponding for the cell Reselection Priority High of high-speed terminal and for other motion states and without the cell Reselection Priority for judging movement velocity terminal.By to different frequency set cell Reselection Priority High, can reach allow F1 gravity treatment priority higher than F2 gravity treatment priority purpose；And in cell Reselection Priority, the gravity treatment priority that can set F1 is less than F2 gravity treatment priority.
Similar, if in order to reach the purpose for allowing middling speed or low speed terminal to reside in small cell layer, base station can notify terminal：For the fast terminals of middling speed Huo Shi, F1 gravity treatment You Xianjishi is in F2 gravity treatment priority；Simultaneously for other states or without for the terminal for judging motion state, F1 weight The gravity treatment priority for selecting priority to be higher than F2.Middling speed or low speed terminal is allowed to be intended to reside in cell and other state terminals or the purpose for residing in macrocell layer without the terminal for judging the SOT state of termination in this manner it is possible to reach.Its specific notification procedure is similar with process described above.
(three）Cell reselection frequency set
In cell reselection frequency set comprising specified type cell where frequency or the specified type cell not frequency, so as to determine the object of cell reselection according to the cell reselection frequency set by terminal, and finally reselect to the cell of the specified type.
Frequency in first way, i.e. cell reselection frequency set where the cell comprising specified type, is set forth below wherein three kinds specific embodiments：
1) frequency that high-speed terminal is reselected to where macrocell layer, is assumed, then base station is to the frequency where just not including small cell layer in the cell reselection set of high-speed terminal.This notification procedure can be realized by unicast and/or multicast message.Such as, macrocell layer is in frequency F1, and small cell layer is in frequency F2, so base station is when notifying terminal, for high-speed terminal, its cell reselection frequency set includes F1 without including F2, and for other state terminals or state terminal is judged, then including F2 in its cell reselection frequency set.So high-speed terminal would not would not also reside in small cell layer using cell as gravity treatment object, and other-end can then reside in small cell layer with gravity treatment.
During specific notice, such as in LTE-A systems, base station can notify cell reselection set when terminal is directed to fast state when notifying terminal in RRC Connection Release unicast messages（Do not include F2) and cell reselection frequency set (including F2) for other states and without judgement state.Except unicast messages, it would however also be possible to employ broadcast message, such as there is provided two reselection frequency set in the SIB5 broadcast messages of macrocell：Cell reselection frequency set for high-speed terminal does not include F2, and includes F2 for other motion states and the cell reselection frequency set without the terminal for judging motion state.By such scheme, then for now residing on F1, still its motion state is the terminal of high speed, F2 should not be considered further that during gravity treatment, so as to be resident the corresponding macrocell layers of F1.
Similar, if system wishes that middling speed or low speed terminal reside in small cell layer, then base station, which is supplied in the cell reselection frequency set of middling speed or low speed terminal, does not just include the frequency where macrocell layer.During specific notice, still by taking lte-a system as an example, terminal can be notified for the cell reselection frequency set of middling speed or low speed terminal in RRC Connection Release unicast messages（Do not include Fl) and for other states or the terminal without judgement state cell reselection frequency set（Including F1).And for the form of broadcast, can there is provided two cell reselection frequency set in the SIB5 broadcast messages of cell：For the cell reselection frequency set of middling speed or low speed terminal（Do not include F1) and for other motion states or without in the cell reselection frequency set for judging motion state（Including F1).By such scheme, then for now residing on F2, still its motion state is middling speed or the terminal of low speed, and Fl should not be considered further that during gravity treatment.
2), base station includes the frequency where macrocell layer and small cell layer to the cell reselection set of high-speed terminal, wherein, added with selection mark in the corresponding frequency of macrocell layer, this mark can notify high-speed terminal to select to identify corresponding frequency.This notification procedure can be realized by unicast and/or multicast message.Such as, macrocell layer is in frequency F1, and small cell layer is in frequency F2, so base station is when notifying terminal, for high-speed terminal, its cell reselection frequency set includes the presence of selection mark on F1 and F2, but F1, and this mark can notify high-speed terminal to select to identify corresponding frequency；And also including the presence of selection mark on F1 and F2, but F2 for other state terminals, in its cell reselection frequency set, this mark can notify other state terminals to select to identify corresponding frequency；And for no judgement state terminal, the F1 and F2 for being not added with mark are then included in its cell reselection set.So high-speed terminal may be selected by the Fl with selection mark, so that small cell layer will not would not be also resided in using cell as gravity treatment object, and other-end can then reside in small cell layer with gravity treatment.
Similar, if system wishes that middling speed or low speed terminal reside in small cell layer, so base station includes the frequency where macrocell layer and small cell layer to the cell reselection set of middling speed or low speed terminal, wherein, added with selection mark in the corresponding frequency of small cell layer.
3), base station includes the frequency where macrocell layer and small cell layer, in addition to selection message to the cell reselection set of high-speed terminal, for selection operation of the instruction terminal for frequency.This notification procedure can be realized by unicast and/or multicast message.Such as, macrocell layer is in frequency F1, and small cell layer is in frequency F2, then base station is when notifying terminal, and for high-speed terminal, its cell reselection frequency set includes F1 and F2, and to F1 selection message；And also include F1 and F2 for other state terminals, in its cell reselection frequency set, and to F2 selection message；And for no judgement state terminal, F1 and F2 is then only included in its cell reselection set.So high-speed terminal just can choose F1 according to selection message, so that gravity treatment pair will not be regard cell as As, small cell layer would not be also resided in, and other-end can then reside in small cell layer with gravity treatment.During specific notice, such as there is provided related selection message in the SIB3 broadcast messages of macrocell：High-speed terminal for just residing in current service cell, it needs the frequency F1 for considering current service cell in gravity treatment;And for other motion states to without judging the terminal of motion state there is provided related message of ignoring, the frequency Fl for pointing out it to need to ignore current service cell in gravity treatment.So, for now reside on F1 and its motion state be high speed terminal, Fl should be considered during gravity treatment.There is provided related selection message in the SIB3 broadcast messages of cell for another example：Middling speed or low speed terminal for just residing in current service cell, it needs the frequency F2 for considering current service cell in gravity treatment;And for other motion states to without judging the terminal of motion state there is provided related message of ignoring, the frequency F2 for pointing out it to need to ignore current service cell in gravity treatment.So, for now residing on F2, still its motion state is the terminal of high speed, and gravity treatment is also not consider further that F2.
Similar, if system wishes that middling speed or low speed terminal reside in small cell layer, so base station includes the frequency where macrocell layer and small cell layer to the cell reselection set of middling speed or low speed terminal, also include the selection message for small cell layer, for indicating that middling speed or low speed terminal select small cell layer.
In the second way, i.e. cell reselection frequency set the cell comprising specified type not frequency, then can now specify " not frequency " in several ways, two of which specific embodiment is set forth below：
1), base station includes the frequency where macrocell layer and small cell layer to the cell reselection set of high-speed terminal, wherein, it is added with the corresponding frequency of small cell layer and ignores mark.This notification procedure can be realized by unicast and/or multicast message.Such as, macrocell layer is in frequency F1, and small cell layer is in frequency F2, so base station is when notifying terminal, for high-speed terminal, its cell reselection frequency set includes F1 and F2, but exist on F2 and ignore mark suitable for high-speed terminal, and for other state terminals, also F1 and F2 is included in its cell reselection frequency set, but there is the mark of ignoring suitable for other state terminals on F1, and for no judgement state terminal, the F1 and F2 for being not added with mark are then included in its cell reselection set.So high-speed terminal, which can just be ignored, has the F2 for ignoring mark, so that small cell layer will not would not be also resided in using cell as gravity treatment object, and other-end can then reside in small cell layer with gravity treatment. Similar, if system wishes that middling speed or low speed terminal reside in small cell layer, so base station includes the frequency where macrocell layer and small cell layer to the cell reselection set of middling speed or low speed terminal, wherein, it is added with the corresponding frequency of macrocell layer and ignores mark.
2), base station includes the frequency where macrocell layer and small cell layer to the cell reselection set of high-speed terminal, in addition to ignores message, ignores operation for frequency for instruction terminal.This notification procedure can be realized by unicast and/or multicast message.Such as, macrocell layer is in frequency F1, and small cell layer is in frequency F2, then base station is when notifying terminal, and for high-speed terminal, its cell reselection frequency set includes F1 and F2, and ignores message to F2；And also include F1 and F2 for other state terminals, in its cell reselection frequency set, and message is ignored to F1；And for no judgement state terminal, F1 and F2 is then only included in its cell reselection set.So high-speed terminal just can choose F2 according to message is ignored, so that small cell layer will not would not be also resided in using cell as gravity treatment object, and other-end can then reside in small cell layer with gravity treatment.
During specific notice, such as ignore message there is provided related in the SIB3 broadcast messages of cell：High-speed terminal for just residing in current service cell, the frequency F2 for pointing out it to need to ignore current service cell in gravity treatment;And for other motion states to without the terminal of motion state is judged there is provided related selection message, it needs the frequency F2 for considering current service cell in gravity treatment.So, for now residing on F2, still its motion state is the terminal of high speed, and gravity treatment is also not consider further that F2.Ignore message there is provided related in the SIB3 broadcast messages of macrocell for another example：Middling speed or low speed terminal for just residing in current service cell, the frequency F1 for pointing out it to need to ignore current service cell in gravity treatment;And for other motion states to without the terminal of motion state is judged there is provided related selection message, it constantly needs to consider the frequency Fl of current service cell in gravity treatment.So, for now residing on F2, still its motion state is middling speed or the terminal of low speed, and gravity treatment is also not consider further that Fl.
Similar, if system wishes that middling speed or low speed terminal reside in small cell layer, so base station includes the frequency where macrocell layer and small cell layer to the cell reselection set of middling speed or low speed terminal, also include being directed to the selection message of small cell layer and/or ignore message for macrocell layer, for indicating middling speed or the small cell layer of low speed terminal selection and/or ignoring macrocell layer.
(four）Cell reselection time set
Terminal is when reselecting to some cell, and the signal intensity or quality of the cell must be better than default Numerical value and can continuously it keep the default period, variable such as some gauge signal quality is r, set when continuing n seconds the r times for being more than or not less than m, just allow terminal to reselect to corresponding cell, " n seconds " now set are cell reselection time Treselecti。n.Therefore, when the cell reselection time of some cell is shorter than other cells, lower equivalent to reselection requirement to the cell, then comparatively terminal is easier to reselect to the cell.
Specifically, the terminal of different motion state can be directed to, when performing cell reselection, different cell reselection times is applied to same frequency.Such as high-speed terminal is avoided to reside in small cell layer, so for high-speed terminal, the corresponding cell reselection time of frequency where its cell should will be longer than other motion states or without judging the cell reselection time that the terminal of motion state is applied, and for high-speed terminal itself, the corresponding cell reselection time of frequency where the corresponding cell reselection time of frequency where cell should be longer than macrocell.Base station can notify the different districts reselection time corresponding to terminal different conditions by unicast or broadcast message.
During specific notice, such as in LTE-A systems, branch determines macrocell layer in frequency F1, and small cell layer is in frequency F2.So, in the SIB5 of macrocell, base station can broadcast two cell reselection times for being directed to F2：The cell reselection time of cell reselection time and other-end for high-speed terminal, the former will be longer than the latter, and for high-speed terminal, it is less than the cell reselection time for F2 for F1 cell reselection time；And in the SIB3 of cell, base station can broadcast two cell reselection times for being directed to F2：Cell reselection time for high-speed terminal and the cell reselection time for other-end, the former will be longer than the latter, and for high-speed terminal, it is less than the cell reselection time for F2 for F1 cell reselection time.In this way, high-speed terminal gravity treatment to the time of small cell layer can be longer, reduce gravity treatment to the probability of small cell layer, high-speed terminal is reselected to macrocell layer as far as possible.
Similar, if avoiding middling speed or low speed terminal from residing in macrocell layer, so its processing method is similar with the processing method to high-speed terminal, i.e. when macrocell layer is in frequency F1, and small cell layer is in frequency F2, middling speed or low speed terminal are then directed to, the corresponding cell reselection times of F1 will be longer than the corresponding cell reselection times of F2.
(five）Reselection criterion thresholding value set
If the measurement result of neighbor cell meets certain cell reselection criterion, terminal just can be with that cell of gravity treatment highest priority into the neighbor cell for meet condition.It is specific as follows： 1st, for the neighbor cell in higher priority frequency, if system configuration serving cell low quality thresholding（ ThreshServing, L。WQ), then, if the quality of neighbor cell is better than high priority quality threshold in the corresponding cell reselection time of its frequency（Threshx, HighQ), and terminal is in current service cell residence time more than 1 second, then, terminal just can be with gravity treatment to this cell；If system is configured without serving cell low quality thresholding, then, if the signal intensity of neighbor cell is better than high priority strength threshold in the corresponding cell reselection time of its frequency（ Threshx, HighP), and terminal is resident more than 1 second in current service cell, then, terminal just can be with gravity treatment to this cell.
2nd, in All factors being equal, preference will be give to level frequency or co-frequency cell, if in cell reselection time section, the measurement result of neighbor cell is better than serving cell according to ranking criteria, and terminal is resident more than 1 second in current service cell, so, terminal just can be with gravity treatment to this cell.
3rd, for the neighbor cell in lower priority frequency, if system configuration serving cell low quality thresholding, so, in the corresponding cell reselection time of its frequency, if the quality of serving cell is less than serving cell low quality thresholding, meanwhile, the quality that neighbor cell measurement goes out is better than low priority quality threshold（ Threshx, L。W), and terminal is resident more than 1 second in current service cell Q, then, terminal just can be with gravity treatment to this cell；If system is configured without serving cell low quality thresholding, then, in the corresponding cell reselection time of frequency where neighbor cell, if the signal intensity of serving cell is less than serving cell strength thresholding（ThreshServing, L。wP), meanwhile, the signal intensity that neighbor cell measurement goes out is better than low priority strength threshold（Threshx, L。wP), and terminal is resident more than 1 second in current service cell, then, terminal just can be with gravity treatment to this cell.
If the 4, multiple cells meet above-mentioned reselection criterion, then terminal should gravity treatment to wherein have limit priority cell.
Due to there is above-mentioned reselection criterion, for the terminal of different motion state, when performing gravity treatment with cell in current frequency different priorities frequency, different reselection criterion threshold values can be used.Specifically, it is assumed that macrocell layer is in F1 in system, and small cell layer has two kinds of situations in F2：
Situation 1:F1 priority is higher than F2 priority.
Situation 2:F2 priority is higher than F1 priority.
If system wishes that high-speed terminal is intended to select macrocell layer, then the processing of threshold value is as follows： In case 1：High-speed terminal in the macro cell base station notifying cell serving cell threshold value lower than other-end（Such as high-speed terminal, its serving cell threshold value is less than some default threshold value, and for other-end, its serving cell threshold value is equal to the predetermined threshold value）, meanwhile, corresponding to the frequency less than service frequency priority（It is F2 herein), notify the low priority measurement thresholding that high-speed terminal is higher than other-end（Such as high-speed terminal, its low priority measurement thresholding is higher than some default threshold value, and for other-end, its low priority measurement thresholding is equal to the predetermined threshold value）；And in cell, corresponding to the frequency higher than service frequency priority（It is F1 herein), notify the high priority measurement thresholding that high-speed terminal is lower than other-end（Such as high-speed terminal, its high priority measurement thresholding is less than some default threshold value, and for other-end, its high priority measurement thresholding is equal to the predetermined threshold value）.Specifically, in lte-a system：
If (a) system is provided with serving cell low quality thresholding（ ThreshServing, L。WQ), then in the SIB3 of macrocell, two serving cell low quality thresholdings should be set： ThreshServing, L.WQ, High and ThreshServing, L。WQ, is respectively supplied to high-speed terminal and other-end, and the former is less than the latter.In macrocell SIB5, it should in the corresponding information of F2, two low priority quality thresholds are set： Threshx, L。WQ, HighAnd Threshx, L。WQ, is respectively supplied to high-speed terminal and other-end, and the former is more than the latter.So, the highspeed user in F1 can be more difficult to gravity treatment to F2.
In addition, in the SIB5 of cell, two high priority quality thresholds can also be set in the corresponding information of F1： ThreshxHighQ. High and Threshx mgHQ, is respectively supplied to high-speed terminal and other-end, and the former is less than the latter.So, the highspeed user in F2 will be more prone to gravity treatment to F1.
If (b) system is not provided with serving cell low quality thresholding, then in the SIB3 of macrocell, two serving cell low-intensity thresholdings should be set： ThreshServing, LowP , ffighWith
Threshservina, LowP, are respectively supplied to high-speed terminal and other-end, and the former is less than the latter.In macrocell SIB5, it should in the corresponding information of F2, two low priority strength threshold Thresh are setx, LowP, HighAnd Threshx, LowPHigh-speed terminal and other-end are respectively supplied to, and the former is more than the latter.So, the highspeed user in F1 can be more difficult to gravity treatment to F2.Meanwhile, in the SIB5 of cell, it should in the corresponding information of F1, two high priority strength threshold Thresh are setx, HighP, HighAnd Threshx, ffighPHigh-speed terminal and other-end are respectively supplied to, and it is preceding Person is less than the latter.So, the highspeed user in F2 will be more prone to gravity treatment to Fl.
In situation 2：In macrocell, corresponding to the frequency higher than service frequency priority（It is F2 herein), notify the high priority measurement thresholding that high-speed terminal is higher than other-end（Such as high-speed terminal, its high priority measurement thresholding is higher than some default threshold value, and for other-end, its high priority measurement thresholding is equal to the predetermined threshold value）.High-speed terminal that should be in notifying cell in the cell serving cell threshold value higher than other-end（Such as high-speed terminal, its serving cell threshold value is higher than some default threshold value, and for other-end, its serving cell threshold value is equal to the predetermined threshold value）, meanwhile, corresponding to the frequency less than service frequency priority（It is F 1 herein), notify the low priority measurement thresholding that high-speed terminal is lower than other-end（Such as high-speed terminal, its low priority measurement thresholding is less than some default threshold value, and for other-end, its low priority measurement thresholding is equal to the predetermined threshold value）.Specifically, in LTE-A systems：
If (a) system is provided with serving cell low quality thresholding（ ThreshServing, L。WQ), then in the SIB5 of macrocell, it should in the corresponding information of F2, two high priority quality thresholds are set： ThreshxHighQ High and Threshx mgHQ, is respectively supplied to high-speed terminal and other-end, and the former is more than the latter.So, the highspeed user in F1 can be more difficult to gravity treatment to F2.
In addition, in the SIB3 of cell, two serving cell low quality thresholdings can also be set： ThreshServing, LowQ, HighAnd ThreshServing, L。wQ, high-speed terminal and other-end are respectively supplied to, and the former is more than the latter.In the SIB5 of cell, it should in the corresponding information of F1, two low priority quality thresholds are set： Threshx, L。WQ, ffighAnd Threshx, L。WQ, is respectively supplied to high-speed terminal and other-end, and the former is less than the latter.So, the highspeed user in F2 will be more prone to gravity treatment to F1.
If (b) system is not provided with serving cell low quality thresholding, then in macrocell SIB5 in the corresponding information of F2, two high priority strength thresholds are set： Threshx, HighP, HighAnd Threshx, HighP, high-speed terminal and other-end are respectively supplied to, and the former is more than the latter.So, the highspeed user in F1 can be more difficult to gravity treatment to F2.
In addition, in the SIB3 of cell, two serving cell low-intensity thresholdings can also be set： ThreshServing, L。wP, High and ThreshServing, L。wP, it is respectively supplied to high-speed terminal and other ends End, and the former is more than the latter.In cell SIB5, it should in the corresponding information of F1, two low priority strength thresholds are set： Threshx, L。wP, ffighAnd Threshx, L。wP, high-speed terminal and other-end are respectively supplied to, and the former is less than the latter.So, the highspeed user in F2 will be more prone to gravity treatment to F1.
Similar, if allowing low speed or middling speed terminal to try one's best resides in some cell layer, the process similar with the above method can be taken, here is omitted.

Fig. 7 is the block diagram of the system of embodiment illustrated in fig. 2.
As shown in fig. 7, the embodiment also proposed a kind of system 700, including base station 400 as shown in Figure 4, and terminal 600 as shown in Figure 6. Embodiment two

And for terminal, receive after the cell reselection frequency set, therefrom selection corresponds to the cell reselection frequency of itself translational speed, to perform cell reselection operation.It is high-speed terminal such as to assume the terminal 804A in figure, then terminal 804A can therefrom choose macrocell frequency and carry out cell reselection operation when receiving cell reselection frequency set, and small cell frequency can not then be responded；4 it is blunt determine the fast terminals of terminal 804B Wei Shi, then terminal 804B can therefrom choose small cell frequency and carry out cell reselection operation when receiving cell reselection frequency set, and macrocell frequency can not then be responded.Similarly, the frequency of certain class cell only can also therefrom be chosen (not shown in figure for middling speed terminal）.
Through the above way, then the terminal of different translational speeds can be with gravity treatment to most suitable cell, such as high-speed terminal, macrocell can be reselected to as much as possible, avoid when reselecting to cell, unnecessary frequent gravity treatment is carried out in an idle state, while also avoiding needing to carry out unnecessary switching upon entering the connected state, causes to increase the unnecessary power dissipation overhead of terminal.

Constituted relative to the handling process of the base station side shown in Fig. 9 and Figure 10 and base station, for terminal, as shown in Figure 11, its flow for carrying out cell reselection according to the cell reselection frequency set of acquisition includes：
Step 1102, the translational speed of itself is obtained.
