Embodiment
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The flow chart of the changing method of subscriber equipment in community between major-minor carrier wave that Fig. 1 provides for the embodiment of the present invention one.As shown in Figure 1, the changing method of subscriber equipment in community between major-minor carrier wave of the present embodiment, specifically can comprise the following steps:
Step 100, according to pre-conditioned, to radio network controller send carrier switch request; Carrier switch request comprises the frequency of current carrier k;
Step 101, to radio network controller send parameter sets, for radio network controller according to carrier switch request and parameter sets, subscriber equipment is switched on other carrier waves in Serving cell outside frequency.
Particularly, the changing method of subscriber equipment in community between major-minor carrier wave of the present embodiment, can according to the condition preset, when pre-conditioned establishment, carrier switch request is sent to RNC, wherein this carrier switch request comprises the frequency of the current carrier k of UE, namely the frequency range numbering of current carrier k.The frequency of main carrier included in community and the frequency of all auxiliary carrier waves are by the system message of community or by downlink signaling during UE access community or by sending to the Survey control message informing of UE to UE.Meanwhile, subscriber equipment also needs to send one group of above-mentioned parameter sets to RNC, and RNC, according to the carrier switch request received and above-mentioned parameter sets, just can realize being switched to by UE on other carrier waves outside carrier wave k.Particularly, when carrier wave k is main carrier, RNC realizes UE to switch on any one auxiliary carrier wave, and when carrier wave k is auxiliary carrier wave, RNC realizes UE to switch on main carrier or on other auxiliary carrier waves.Community described here is Serving cell.
The changing method of subscriber equipment in community between major-minor carrier wave of the present embodiment, by according to the condition preset, sends carrier switch request, to realize the switching in community between major-minor carrier wave to RNC.Adopt the technical scheme of the present embodiment, effectively can support the network collocating method of existing TD-SCDMA system, contribute to eliminating the co-channel interference between neighbor cell, and then contribute to improving the handover success rate between cell capacity and community.
The flow chart of the changing method of subscriber equipment in community between major-minor carrier wave that Fig. 2 provides for the embodiment of the present invention two.As shown in Figure 2, the present embodiment for the executive agent of the changing method of subscriber equipment in community between major-minor carrier wave for UE, describe technical scheme of the present invention in detail, as shown in Figure 2, the changing method of subscriber equipment in community between major-minor carrier wave of the present embodiment, specifically can comprise the steps:
Step 200, under current carrier k, UE judges whether the co-channel interference power of UE exceedes co-channel interference threshold value;
Particularly, under current carrier k, UE judges whether the co-channel interference power of self exceedes co-channel interference threshold value, can comprise following two kinds of modes:
The first, UE judges that the up co-channel interference power of self or descending co-channel interference power exceed co-channel interference threshold value, then think that the co-channel interference power of UE exceedes co-channel interference threshold value;
The second, UE judges that the up co-channel interference power of self and descending co-channel interference power all exceed co-channel interference threshold value, just thinks that the co-channel interference power of UE exceedes co-channel interference threshold value.
And wherein, UE judges whether the up co-channel interference power of self exceedes co-channel interference threshold value and also comprise following two kinds of situations:
(1) under carrier wave k, in triggered time t, as long as have the transmitting power of a up channel to exceed co-channel interference threshold value to the interference power that co-frequency neighbor cell is caused in each up channel of UE, then UE thinks that the up co-channel interference power of self exceedes co-channel interference threshold value;
It should be noted that, around this community that co-frequency neighbor cell here refers to UE place, use the community of carrier wave k.For carrier wave k, the ID of each community of this carrier wave k in peripheral cell, is used just to form the co-frequency neighbor cell list of this carrier wave k.
The downlink signaling of RNC by the system message of community or when accessing community by UE or co-frequency neighbor cell list is informed to UE by Survey control message.Or, by UE oneself by measuring the co-frequency neighbor cell list obtaining place carrier wave k.
(2) under carrier wave k, in triggered time t, the transmitting power of each up channel of UE all exceedes co-channel interference threshold value to the interference power that co-frequency neighbor cell is caused, then UE thinks that the up co-channel interference power of self exceedes co-channel interference threshold value.
In like manner, UE judges whether the descending co-channel interference of self exceedes co-channel interference threshold value and also comprise following two kinds of situations:
(1) under carrier wave k, in triggered time t, as long as have the received power of a down channel to exceed co-channel interference threshold value to the interference power that co-frequency neighbor cell is caused in each down channel of UE, then UE thinks that the descending co-channel interference power of self exceedes co-channel interference threshold value;
(2) under carrier wave k, in triggered time t, the received power of each down channel of UE all exceedes co-channel interference threshold value to the interference power that co-frequency neighbor cell is caused, then UE thinks that the descending co-channel interference power of self exceedes co-channel interference threshold value.
Co-channel interference threshold value described in above-mentioned can be biased sum for initial co-channel interference threshold value and co-channel interference.The initial co-channel interference threshold value of the type channel can be set respectively for dissimilar up channel or dissimilar down channel and co-channel interference is biased.Like this, the channel of every type all has the co-channel interference threshold value of oneself.When judging whether in the type channel channel exceedes co-channel interference threshold value to the co-channel interference of adjacent cell, the initial co-channel interference threshold value and the co-channel interference that are adopted as the setting of the type channel are biased the co-channel interference threshold value of sum as the type channel.Also can be that all types of up channel unifications arrange initial co-channel interference threshold value and co-channel interference is biased.Like this, all up channels have identical co-channel interference threshold value.Also can be that all types of down channel unifications arrange initial co-channel interference threshold value and co-channel interference is biased.Like this, all down channels have identical co-channel interference threshold value.Certainly, unified initial co-channel interference threshold value can also be set for up channel and down channel and co-channel interference is biased.Like this, all channels have identical co-channel interference threshold value.
Step 201, when the co-channel interference power of UE exceedes co-channel interference threshold value, UE sends carrier switch request by Node B to RNC;
Particularly, through the judgement of above-mentioned steps 200, when the co-channel interference power of UE exceedes co-channel interference threshold value, UE sends carrier switch request by Node B to RNC; This carrier switch request comprises the frequency of UE current carrier k.
Step 202, UE send parameter sets by Node B to RNC, for RNC according to carrier switch request and parameter sets, on other carrier waves outside frequency UE being switched to Serving cell, UE place.
Here each community path loss that UE comprises in community by Node B to the parameter sets that RNC reports, the co-frequency neighbor cell list of each carrier wave outside the path loss of each carrier wave outside current carrier k and current carrier k comprises.
Particularly, RNC will carry out major-minor carrier switch to UE, also needs UE while transmission carrier switch request, then sends one group of parameter sets.UE according to carrier switch request, in conjunction with this group parameter sets received, can switch on another carrier wave outside current carrier k by RNC.It should be noted that, carrier switch is major-minor carrier switch here, and when the current carrier k of UE is main carrier, the carrier wave k ' be switched to is auxiliary carrier wave.And when the current carrier k of UE is auxiliary carrier wave, the carrier wave k ' be switched to is main carrier or another auxiliary carrier wave.
The changing method of subscriber equipment in community between major-minor carrier wave of the present embodiment, UE is by judging whether the co-channel interference power of self exceedes co-channel interference threshold value; The request of switched carrier is sent to RNC, to realize the switching of carrier wave when exceeding.By adopting the technical scheme of the present embodiment, RNC is can be used for more exactly UE to be carried out to the switching of major-minor carrier wave.
It should be noted that, in above-described embodiment, UE obtains the power of channel to the interference power of co-frequency neighbor cell, here for channel u, specifically can adopt with the following method:
UE is according to formula estimate the interference power P that the power that the carrier wave k of the n-th subframe distributes to the channel u of UE causes co-frequency neighbor cell i(k, u, n); Wherein P (k, u, n) represents transmitting power (when channel u is up channel) or the received power (when channel u is down channel) of the channel u on the carrier wave k of the n-th subframe; The method that UE calculates P (k, u, n) with reference to prior art, can not repeat them here.L (k, c) represents the path loss of c community in the co-frequency neighbor cell list of the carrier wave k of this community in the individual community of C (k).Here the numerical value of L (k, c) is estimated to obtain by UE oneself, and UE can also estimate the path loss L of this community simultaneously.
Or UE can also according to formula estimate the interference power P that the power of the channel u on the carrier wave k of the n-th subframe causes co-frequency neighbor cell i(k, u, n);
Adopt said method can estimate the interference power that the transmitting power of up channel u causes co-frequency neighbor cell; Also the interference power that the received power of down channel u causes co-frequency neighbor cell can be estimated.
It should be noted that, on the basis of above-described embodiment, if UE has the ability to record the interference power of each descending time slot of any one carrier wave in community outside current carrier k, UE is reported in the parameter sets of RNC except comprising first group of above-mentioned parameter " in community by Node B, the path loss of each community that the co-frequency neighbor cell list of each carrier wave outside the path loss of each carrier wave outside current carrier k and current carrier k comprises " outside, second group of parameter " interference power of each descending time slot of any one carrier wave outside current carrier k " can also be comprised in parameter sets.
Above-mentioned first group of parameter is that UE is bound to report RNC.On the basis reporting first group of parameter, above-mentioned second group of parameter can also be reported, in practical application, whether report above-mentioned second group of parameter to the ability of RNC depending on UE.When UE has the ability the interference power of each descending time slot recording any one carrier wave outside current carrier k, namely this group parameter sets can be reported RNC by Node B by UE.
By adopting above technical scheme, RNC is can be used for more exactly UE to be carried out to the switching of major-minor carrier wave.
The flow chart of the changing method of subscriber equipment in community between major-minor carrier wave that Fig. 3 provides for the embodiment of the present invention three.As shown in Figure 3, the present embodiment for the executive agent of the changing method of subscriber equipment in community between major-minor carrier wave for UE, describe technical scheme of the present invention in detail, as shown in Figure 3, the changing method of subscriber equipment in community between major-minor carrier wave of the present embodiment, specifically can comprise the steps:
Step 300, UE obtain Doppler shift value;
Step 301, UE judge Doppler shift value be on the occasion of or duration of negative value whether more than the first prefixed time interval;
Step 302, when UE judge Doppler shift value be on the occasion of duration or duration of negative value more than the first prefixed time interval time, UE sends carrier switch request by Node B to RNC, and performs step 304;
Step 303, when UE judge Doppler shift value be on the occasion of duration or duration of negative value more than the first prefixed time interval time, UE does not perform any operation.
Step 304, UE report the trigger condition and Doppler shift value that are designated Doppler shift to RNC by Node B; Simultaneously UE reports parameter sets by Node B to RNC, for the positive and negative and parameter sets of RNC according to carrier switch request, trigger condition, Doppler shift value, on other carrier waves outside frequency UE being switched to Serving cell, UE place.
Here parameter sets is identical with above-described embodiment two, and this parameter sets comprises first group of parameter " path loss of each community that the path loss of each carrier wave outside the intercarrier k of this community and the co-frequency neighbor cell list of each carrier wave comprise ".When UE has the ability to record the interference power of each descending time slot of any one carrier wave in community outside current carrier k, described parameter sets also comprises second group of parameter " interference power of each descending time slot of any one carrier wave outside current carrier k ".
In the present embodiment, the trigger condition that UE is arranged is Doppler shift.In the parameter sets that UE reports to RNC, except comprising the parameter sets described in above-described embodiment two, also need to report trigger condition and Doppler shift value.Such RNC, according to the positive and negative and parameter sets of the trigger condition received, Doppler shift, carries out switching to UE and selects.
In the present embodiment, the method that UE obtains Doppler shift value has following two kinds:
(1) UE can carry out the estimation of Doppler shift according to the Received signal strength of each down channel, obtains the Doppler shift of each down channel.Ask the mean value of the Doppler shift value of all down channels.Using the Doppler shift value of this mean value as UE.
(2) UE can select a down channel from all belonging to its down channel, carries out the estimation of Doppler shift, obtain the Doppler shift of this down channel according to the Received signal strength of this down channel.Using the Doppler shift value of this Doppler shift value as UE.
When UE is on main carrier, UE judge Doppler shift value be on the occasion of duration whether more than the first prefixed time interval T1; When UE judge Doppler shift be on the occasion of the time time interval T1 default more than time, now show that UE continues to move to this center of housing estate.Now UE can ask the switching carried out in community between major-minor carrier wave, so that UE is switched to auxiliary carrier wave to RNC.
When UE is on auxiliary carrier wave, UE judges that Doppler shift value is whether the duration of negative value is more than the first prefixed time interval T1.When UE judges that Doppler shift is time of negative value time interval T1 default more than, now show that UE continues to move to cell edge.Now UE can ask the switching carried out in community between auxiliary main carrier, so that UE is switched to main carrier to RNC.
UE, when sending handover request, also needs to report to RNC the trigger condition and Doppler shift value that trigger this handover request.UE is set to Doppler shift by triggering the trigger condition of this handover request, represent this handover request due to the Doppler shift of UE be on the occasion of or time of negative value exceed the default time interval and cause.When UE is current be in main carrier time, the Doppler shift value that UE reports is for just.When UE is current be in auxiliary carrier wave time, the Doppler shift value that UE reports is negative.After trigger condition and Doppler shift value are reported RNC by Node B by UE, RNC, according to handover request and the trigger condition received and Doppler shift value and the above-mentioned parameter set that receives, carries out carrier switch to UE.
The changing method of subscriber equipment in community between major-minor carrier wave of the present embodiment, when Doppler shift value be on the occasion of or duration of negative value more than the first prefixed time interval time, send the request of switched carrier to RNC, to realize the switching of carrier wave.Adopt the technical scheme of the present embodiment, effectively can realize the switching of subscriber equipment between major-minor carrier wave.
The flow chart of the changing method of subscriber equipment in community between major-minor carrier wave that Fig. 4 provides for the embodiment of the present invention four.As shown in Figure 4, the present embodiment for the executive agent of the changing method of subscriber equipment in community between major-minor carrier wave for UE, describe technical scheme of the present invention in detail, as shown in Figure 4, the changing method of subscriber equipment in community between major-minor carrier wave of the present embodiment, specifically can comprise the steps:
Step 400, UE obtain path loss decimal reduction time or the path loss progressive time of this community;
Step 401, UE judge that whether the path loss decimal reduction time of this community or progressive time are more than the second prefixed time interval;
Step 402, when UE judges the path loss decimal reduction time of this community or progressive time more than the second prefixed time interval, UE sends carrier switch request by Node B to RNC, and performs step 404;
Step 403, when UE judges the path loss decimal reduction time of this community or progressive time more than the second prefixed time interval, UE does not perform any operation.
Step 404, UE report the trigger condition being designated path loss to RNC by Node B, UE reports parameter sets by Node B to RNC simultaneously; For RNC according to carrier switch request and this trigger condition and parameter sets, UE is switched on other carrier waves in community outside frequency.
In the present embodiment, the trigger condition that UE is arranged is path loss.In the parameter sets that UE reports to RNC, except comprising the parameter sets described in above-described embodiment two, also need to report trigger condition path loss.Like this when RNC receives this trigger condition and parameter sets, switching is carried out to UE and selects.
Namely community in the present embodiment refers to the Serving cell at UE place.
Particularly, when on the main carrier that UE is positioned at community, the time that the path loss that UE obtains this community successively decreases; And judge that further whether time that the path loss of this community successively decreases is more than the second prefixed time interval T2.When the time that the path loss of this community successively decreases is more than the second prefixed time interval T2, now show that UE continues center of housing estate to move, now UE can ask the switching carried out in community between major-minor carrier wave, so that UE is switched to auxiliary carrier wave to RNC.
When on the auxiliary carrier wave that UE is positioned at community, the time that the path loss that UE obtains this community increases progressively; And judge that further whether time that the path loss of this community increases progressively is more than the second prefixed time interval T2.When the time that the path loss of this community increases progressively is more than the second prefixed time interval T2, now show that UE continues cell edge to move, now UE can ask the switching carried out between the intercarrier of community, so that UE is switched to main carrier to RNC.UE is when sending handover request, and also need to report to RNC the trigger condition triggering this handover request, RNC, according to handover request, the trigger condition received and above-mentioned parameter sets, carries out carrier switch to UE.
It should be noted that, identical with above-described embodiment two, described parameter sets comprises first group of parameter: the path loss of each community that the path loss of each carrier wave outside the intercarrier k of this community and the co-frequency neighbor cell list of each carrier wave comprise.When UE has the ability to record the interference power of each descending time slot of any one carrier wave in community outside current carrier k, described parameter sets also comprises second group of parameter: the interference power of each descending time slot of any one carrier wave outside current carrier k.
The changing method of subscriber equipment in community between major-minor carrier wave of the present embodiment, when UE judges the path loss decimal reduction time of this community or progressive time more than the second prefixed time interval, UE sends carrier switch request by Node B to RNC, to realize the switching of carrier wave.Adopt the technical scheme of the present embodiment, effectively can realize the switching of subscriber equipment between major-minor carrier wave.
The flow chart of the changing method of subscriber equipment in community between major-minor carrier wave that Fig. 5 provides for the embodiment of the present invention five.As shown in Figure 5, the present embodiment for the executive agent of the changing method of subscriber equipment in community between major-minor carrier wave for Node B, describe technical scheme of the present invention in detail, as shown in Figure 5, the changing method of subscriber equipment in community between major-minor carrier wave of the present embodiment, specifically can comprise the steps:
Step 500, under carrier wave k, Node B judges whether the co-channel interference power of UE exceedes co-channel interference threshold value;
Particularly, under current carrier k, Node B judges whether the co-channel interference power of UE exceedes co-channel interference threshold value, can comprise following two kinds of modes:
The first, Node B judges that the up co-channel interference power of UE or descending co-channel interference power exceed co-channel interference threshold value, and Node B then thinks that the co-channel interference power of UE exceedes co-channel interference threshold value;
The second, Node B judges that the up co-channel interference power of UE and descending co-channel interference power all exceed co-channel interference threshold value, and Node B just thinks that the co-channel interference power of UE exceedes co-channel interference threshold value.
And wherein, Node B judges whether the up co-channel interference power of UE exceedes co-channel interference threshold value and also comprise following two kinds of situations:
(1) under carrier wave k, in triggered time t, as long as Node B judges have the transmitting power of a up channel to exceed co-channel interference threshold value to the interference power that co-frequency neighbor cell is caused in each up channel of UE, Node B then thinks that the up co-channel interference power of UE exceedes co-channel interference threshold value;
It should be noted that, around this community that co-frequency neighbor cell here refers to UE place, use the community of carrier wave k.For carrier wave k, the ID of each community of carrier wave k in peripheral cell, is used just to form the co-frequency neighbor cell list of this carrier wave k.
RNC is by the system message of community or by downlink signaling during UE access community or by sending to the Survey control message of UE that co-frequency neighbor cell list is informed to UE.Or, by UE oneself by measuring the co-frequency neighbor cell list obtaining place carrier wave k.
(2) under carrier wave k, in triggered time t, Node B judges that the transmitting power of each up channel of UE all exceedes co-channel interference threshold value to the interference power that co-frequency neighbor cell is caused, and Node B then thinks that the up co-channel interference power of UE exceedes co-channel interference threshold value.
In like manner, Node B judges whether the descending co-channel interference of UE exceedes co-channel interference threshold value and also comprise following two kinds of situations:
(1) under carrier wave k, in triggered time t, as long as Node B judges have the received power of a down channel to exceed co-channel interference threshold value to the interference power that co-frequency neighbor cell is caused in each down channel of UE, Node B then thinks that the descending co-channel interference power of UE exceedes co-channel interference threshold value;
(2) under carrier wave k, in triggered time t, Node B judges that the received power of each down channel of UE all exceedes co-channel interference threshold value to the interference power that co-frequency neighbor cell is caused, and Node B then thinks that the descending co-channel interference power of UE exceedes co-channel interference threshold value.
Co-channel interference threshold value described in above-mentioned can be biased sum for initial co-channel interference threshold value and co-channel interference.Initial co-channel interference threshold value can be set respectively for the channel of every type and co-channel interference is biased.Also initial co-channel interference threshold value can be set for up channel or down channel are unified and co-channel interference is biased.Certainly, can also be that the unification of all channels arrange initial co-channel interference threshold value and co-channel interference is biased.
Step 501, when the co-channel interference power of UE exceedes co-channel interference threshold value, Node B sends carrier switch request to RNC, and performs step 502;
When the co-channel interference power of UE does not exceed co-channel interference threshold value, Node B does not perform any operation.
Particularly, through the judgement of above-mentioned steps 500, when the co-channel interference power of UE exceedes co-channel interference threshold value, Node B sends carrier switch request to RNC, to ask to carry out major-minor carrier switch to UE; This carrier switch request comprises: the frequency of UE current carrier k.
Step 502, Node B send parameter sets to RNC, for RNC according to carrier switch request and parameter sets, are switched to by UE on other carrier waves in community outside frequency.
Particularly, RNC will carry out major-minor carrier switch to UE, also needs Node B while transmission carrier switch request, sends one group of parameter sets.UE according to carrier switch request, in conjunction with this group parameter sets received, can switch on another carrier wave in community outside current carrier k by RNC.It should be noted that, carrier switch is major-minor carrier switch here, and when the current carrier k of UE is main carrier, the carrier wave k ' be switched to is auxiliary carrier wave.And when the current carrier k of UE is auxiliary carrier wave, the carrier wave k ' be switched to is main carrier or other auxiliary carrier waves.Community is the Serving cell at UE place.
In the present embodiment, the parameter sets that Node B reports RNC comprises following two groups of parameters:
(1) path loss of each community that the path loss of each carrier wave outside community intercarrier k and the co-frequency neighbor cell list of each carrier wave comprise; Or can be the path loss ratio (Serving and Neighbour cell pathloss, hereinafter referred to as SNPL) of the path loss of each carrier wave outside the intercarrier k of community and the Serving cell of each carrier wave and adjacent cell; Here Serving cell namely: this community; Adjacent cell is namely: the co-frequency neighbor cell of this carrier wave;
(2) further, the interference power of each descending time slot recording any one carrier wave outside current carrier k if UE has the ability, these interference powers periodically can be reported Node B by UE; When Node B reports handover request to RNC, the interference power of each descending time slot of any one carrier wave outside the current carrier k of up-to-date acquisition is reported RNC; If these interference powers periodically report RNC by UE, then, when Node B reports handover request to RNC, no longer need to report these parameters to RNC.
By reporting above-mentioned parameter, RNC can switch the carrier wave of UE according to the carrier switch request received and the parameter sets received.By adopting above technical scheme, RNC is can be used for more exactly UE to be carried out to the switching of major-minor carrier wave.
Above-mentioned first group of parameter is that Node B is bound to report RNC, and whether above-mentioned second group of parameter reports the ability of RNC depending on UE.When UE has the ability the interference power of each descending time slot recording any one carrier wave outside current carrier k, this second group of parameter reports RNC by Node B or directly reports RNC by UE.When this second group of parameter reports RNC by Node B, Node B obtains this second group of parameter from UE particularly.
If RNC receives the above-mentioned two groups of parameters in parameter sets, the switching between major-minor carrier wave will be carried out based on above-mentioned two groups of parameters; If RNC receives only first group of parameter, RNC is by only based on the switching that this first group of parameter is carried out in community between major-minor carrier wave to UE.
The changing method of subscriber equipment in community between major-minor carrier wave of the present embodiment, Node B is by judging whether the co-channel interference power of UE exceedes co-channel interference threshold value; The request of switched carrier is sent to RNC, to realize the switching of carrier wave when exceeding.Adopt the technical scheme of the present embodiment, effectively can realize the switching of subscriber equipment between major-minor carrier wave.
It should be noted that, in above-described embodiment, the power obtaining up channel u for up channel u, Node B to the method for the interference power of co-frequency neighbor cell because UE reports the difference of the parameter of Node B and different.
The parameter reporting Node B as UE comprises: the Serving cell of current carrier k and path loss ratio (the Serving and Neighbour cell pathloss of adjacent cell, hereinafter referred to as SNPL) and UE be power headroom (the UE Power Headroom of UE on the current carrier k of UE configuration at RNC, hereinafter referred to as UPH) time, Node B can adopt the transmitting power that the obtains up channel u with the following method transmitting power to the interference power of co-frequency neighbor cell and down channel u to the interference power of co-frequency neighbor cell.
Node B is according to formula P i(k, u, n)=P (k, u, n)-SNPL (k), estimates the interference power P that the power of the up channel u on the carrier wave k of the n-th subframe causes co-frequency neighbor cell i(k, u, n); Wherein P (k, u, n) represents the received power of the up channel u on the carrier wave k of the n-th subframe; The method that Node B calculates P (k, u, n) with reference to prior art, can not repeat them here.SNPL (k) is the path loss ratio in carrier wave k Xia Zhe community and co-frequency neighbor cell that UE reports Node B.
Node B is according to formula P i(k, u, n)=P (k, u, n)-2L-SNPL (k), estimates the interference power P that the transmitting power P (k, u, n) of the down channel u on the carrier wave k of the n-th subframe causes co-frequency neighbor cell i(k, u, n); Wherein the acquisition of this community path loss L can in the following way:
First, the UPH of carrier wave k that NODE B reports according to UE can calculate and strengthen special-channel physical uplink channel (E-DCH Physical Uplink Channel; Hereinafter referred to as E-PUCH) Pe-base and the estimated value of this community path loss L sum (unit: dBm).Circular refers to existing document.
NODE B can calculate the received power (unit: dBm) of E-PUCH on carrier wave k, and calculates the P of this E-PUCH according to the received power of E-PUCH e-baseestimated value (unit: dBm).Calculate the method for the received power of E-PUCH and calculate according to the received power of E-PUCH method refer to existing document.
By the P of E-PUCH e-baseestimated value with the P of above-mentioned E-PUCH e-basewith the estimated value of this community path loss L sum according to formula the estimated value of this community path loss L can be calculated (unit: dB).
When UE reports the path loss of each community in the co-frequency cell list of path loss and the UE operating carriers k including this community in the parameter of Node B, Node B can adopt the transmitting power that the obtains up channel u with the following method transmitting power to the interference power of co-frequency neighbor cell and down channel u to the interference power of co-frequency neighbor cell.
Node B according to the interference power P that the transmitting power obtaining the up channel u on the carrier wave k of the n-th subframe causes co-frequency neighbor cell i(k, u, n).P (k, u, n) represents the received power of the up channel u on carrier wave k.L is the path loss of this community that UE reports, represent the path loss of the community that path loss is minimum in the co-frequency neighbor cell of UE under current carrier k.
Node B can also basis the interference power P that the transmitting power obtaining the up channel u on the carrier wave k of the n-th subframe causes co-frequency neighbor cell i(k, u, n).P (k, u, n) represents the received power of the up channel u on carrier wave k.L (k, c) represents the path loss of c community in the co-frequency neighbor cell list on the carrier wave k of this community in the individual community of C (k).
Node B can adopt the transmitting power of acquisition down channel u with the following method to the interference power of co-frequency neighbor cell.
Node B according to the interference power P that the transmitting power obtaining the down channel u on the carrier wave k of the n-th subframe causes co-frequency neighbor cell i(k, u, n).P (k, u, n) represents the transmitting power of the down channel u on carrier wave k. represent the path loss of the community that path loss is minimum in the co-frequency neighbor cell of UE under current carrier k.

The flow chart of the changing method of subscriber equipment in community between major-minor carrier wave that Fig. 6 provides for the embodiment of the present invention six.As shown in Figure 6, the present embodiment for the executive agent of the changing method of subscriber equipment in community between major-minor carrier wave for Node B, describe technical scheme of the present invention in detail, as shown in Figure 6, the changing method of subscriber equipment in community between major-minor carrier wave of the present embodiment, specifically can comprise the steps:
Step 600, Node B obtain the Doppler shift value of UE;
Step 601, Node B judge the Doppler shift value of UE be on the occasion of or duration of negative value whether more than the first prefixed time interval;
Step 602, when Node B judge the Doppler shift value of UE be on the occasion of or duration of negative value more than the first prefixed time interval time, Node B sends carrier switch request to RNC, and performs step 604;
Step 603, when Node judge the Doppler shift value of UE be on the occasion of or duration of negative value more than the first prefixed time interval time, Node B does not perform any operation.
Step 604, Node B report the trigger condition and Doppler shift value that are designated Doppler shift to RNC, Node B reports parameter sets to RNC simultaneously, for RNC according to carrier switch request, trigger condition and Doppler shift value and the parameter sets that receives, UE is switched on other carrier waves in community outside the frequency of UE place.
Particularly, the method for the Doppler shift value of Node B acquisition UE has following two kinds:
(1) Node B can carry out the estimation of Doppler shift according to the Received signal strength of each up channel of UE, obtains the Doppler shift of each up channel.Ask the mean value of the Doppler shift value of all up channels.Using the Doppler shift value of this mean value as UE.
(2) Node B can select a up channel from all belonging to the up channel of UE, carries out the estimation of Doppler shift, obtain the Doppler shift of this up channel according to the Received signal strength of this up channel.Using the Doppler shift of this Doppler shift value as UE.
When on the main carrier that UE is positioned at community, UE judge the Doppler shift value of UE be on the occasion of duration whether more than the first prefixed time interval T1; When Node B judge the Doppler shift of UE be on the occasion of the time time interval T1 default more than time, now show that UE continues to move to this center of housing estate, now Node B can ask the switching carried out in community between major-minor carrier wave, so that UE is switched to auxiliary carrier wave to RNC.
When on the auxiliary carrier wave that UE is positioned at community, Node B judges that the Doppler shift value of UE is whether the duration of negative value is more than the first prefixed time interval T1; When Node B judges that the Doppler shift of UE is time of negative value time interval T1 default more than, now show that UE continues to move to this cell edge, now Node B can ask the switching carried out in community between major-minor carrier wave, so that UE is switched to main carrier to RNC.
Node B, when sending handover request, also needs to report the trigger condition of switching and Doppler shift value and parameter sets to RNC.When UE is current be in main carrier time, Doppler shift value is just.When UE is current be in auxiliary carrier wave time, Doppler shift value is negative.After trigger condition, Doppler shift value and above-mentioned parameter set are reported RNC by Node B, RNC, according to handover request, the trigger condition received, Doppler shift value and the parameter sets that receives, carries out carrier switch to UE.
In the present embodiment, Node B reports the parameter sets of RNC with embodiment five, comprising:
The path loss of each community that the path loss of each carrier wave outside the intercarrier k of this community and the co-frequency neighbor cell list of each carrier wave comprise;
Or can also be the path loss of each carrier wave outside the intercarrier k of this community and the SNPL of each carrier wave.The path loss of each community that wherein SNPL of each carrier wave can be comprised by the co-frequency neighbor cell list of each carrier wave obtains.
Further, the interference power of each descending time slot recording any one carrier wave outside current carrier k if UE has the ability, these interference powers periodically can be reported Node B by UE; Node B can also report following parameter sets to RNC: the interference power of each descending time slot of any one carrier wave outside the current carrier k of up-to-date acquisition.If these interference powers periodically report RNC by UE, then, when Node B reports handover request to RNC, no longer need to report these parameters to RNC.
By reporting above-mentioned parameter set, RNC can switch the carrier wave of UE according to the carrier switch request received and the parameter sets received.By adopting above technical scheme, RNC is can be used for more exactly UE to be carried out to the switching of major-minor carrier wave.
The changing method of subscriber equipment in community between major-minor carrier wave of the present embodiment, when Node B judge the Doppler shift value of UE be on the occasion of duration or as duration of negative value more than the first prefixed time interval time, Node B sends the request of switched carrier, to realize the switching of carrier wave to RNC.Adopt the technical scheme of the present embodiment, effectively can realize the switching of subscriber equipment between major-minor carrier wave.
The flow chart of the changing method of subscriber equipment in community between major-minor carrier wave that Fig. 7 provides for the embodiment of the present invention seven.As shown in Figure 7, the present embodiment for the executive agent of the changing method of subscriber equipment in community between major-minor carrier wave for RNC, describe technical scheme of the present invention in detail, as shown in Figure 7, the changing method of subscriber equipment in community between major-minor carrier wave of the present embodiment, specifically can comprise the steps:
Step 700, reception carrier handover request, carrier switch request comprises the frequency that UE is in the current carrier k in community;
Step 701, receiving parameter set;
Step 702, according to carrier switch request and parameter sets, UE to be switched on other carrier waves in community outside frequency.
Wherein step 700 and step 701 can perform simultaneously.Community is the Serving cell at UE place.
Particularly, RNC reception carrier handover request, this handover request can be sent by Node B for UE, also can be that Node B sends.This handover request comprises the frequency of the current carrier of the UE be switched, namely the frequency range numbering of current carrier k.
RNC also receives parameter sets that is that UE is sent by Node B or Node B transmission simultaneously.RNC according to the carrier switch request received and parameter sets, can carry out carrier switch to UE.Particularly, when carrier wave k is main carrier, RNC realizes UE to switch on any one auxiliary carrier wave, and when carrier wave k is auxiliary carrier wave, RNC realizes UE to switch on main carrier or the auxiliary carrier wave of another one.
The changing method of subscriber equipment in community between major-minor carrier wave of the present embodiment, RNC carries out major-minor carrier switch according to the carrier switch request received and parameter sets to UE.Adopt the technical scheme of the present embodiment, effectively can realize the switching of subscriber equipment between major-minor carrier wave.Thus effectively support the network collocating method of TD-SCDMA system in prior art, contribute to eliminating the co-channel interference between neighbor cell, and then contribute to improving the handover success rate between cell capacity and community.
The flow chart of the changing method of subscriber equipment in community between major-minor carrier wave that Fig. 8 provides for the embodiment of the present invention eight.As shown in Figure 8, the changing method of the subscriber equipment of the present embodiment in community between major-minor carrier wave specifically can comprise the steps:
Step 800, reception carrier handover request and parameter sets;
Corresponding to above-described embodiment two, three, four, five and six.Pre-conditioned when judging in UE side or Node B side to meet, send carrier switch request to RNC and parameter sets required for carrier wave is switched.Accordingly, RNC reception carrier handover request and parameter sets in the present embodiment.Here the parameter sets received can be the parameter sets that in above-described embodiment two, three, four, five and six, UE or Node B reports respectively, specifically in detail with reference to above-mentioned related embodiment, can not repeat them here.
Step 801, RNC judge whether there is the pre-selected carriers can distributing to the DPCH that UE has on current carrier k in the carrier wave outside current carrier k, if neither one carrier wave can distribute the UE all DPCH had on carrier wave k to UE, perform step 806; Otherwise, perform step 802.
Particularly, after RNC receives carrier switch request, first analyze UE and on current carrier k, which up channel there is, which down channel.When a UE has at least one DPCH on current carrier k, for realizing switching between the intercarrier of community, RNC needs to judge which carrier wave in other carrier waves in community outside current carrier k can redistribute all DPCH that UE has to UE.If a carrier wave does not have sufficient resource can redistribute all DPCH to UE, then UE cannot be switched on this carrier wave.
This DPCH can be uplink special physical channel, also can be downward special physical channel.UE only can have uplink special physical channel on carrier wave k, only can have downward special physical channel, also can have uplink special physical channel and downward special physical channel simultaneously.Such as: the DPCH that UE has can be uplink special physical channel (Uplink Dedicated PhysicalChannel; Hereinafter referred to as UL DPCH), downward special physical channel (Downlink DedicatedPhysical Channel; Hereinafter referred to as DL DPCH) and non-scheduled enhancing special-channel physical uplink channel (E-DCH Physical Uplink Channel; Hereinafter referred to as E-PUCH) in one or more.
When UE has a more than DPCH on carrier wave k, but when RNC cannot distribute these DPCH to UE on a carrier wave simultaneously, UE cannot be switched to this carrier wave.Such as: when UE has UL DPCH and DL DPCH simultaneously, if RNC is merely able to for UE distributes DL DPCH on a carrier wave k ', but cannot distribute UL DPCH for UE, then UE cannot be switched to this carrier wave k '.
RNC is according to above-mentioned criterion, and can distribute each carrier wave k ' with all DPCH that UE has on carrier wave k to UE, these carrier waves k ' is as pre-selected carriers.
Step 802, for any one pre-selected carriers, judge whether this pre-selected carriers supports the high-speed packet access service that UE has on carrier wave k.If neither one pre-selected carriers can support the high-speed packet access service that UE has on carrier wave k, perform step 806; Otherwise, perform step 803.
Particularly, when UE has high-speed slender body theory (High Speed DownlinkPacket Access on carrier wave k; Hereinafter referred to as HSDPA) business time, if a pre-selected carriers k ' does not support HSDPA business, then UE can not be switched on this carrier wave k '; If a carrier wave k ' support HSDPA business, then can be switched to UE on this carrier wave k '.
When UE has high speed uplink packet access (high speed uplink packet access on carrier wave k; Hereinafter referred to as HSUPA) business time, if a carrier wave k ' does not support HSUPA business, then UE can not be switched on this carrier wave k '; If a carrier wave k ' support HSUPA business, then can be switched to UE on this carrier wave k '.
When UE has HSDPA business and HSUPA business on carrier wave k simultaneously, if a carrier wave k ' supports HSDPA business and HSUPA business simultaneously, then UE can not be switched on this carrier wave k '; If a carrier wave k ' supports HSDPA business and HSUPA business simultaneously, then UE can be switched on this carrier wave k '.
According to above-mentioned criterion, the carrier wave k ' of determining step 801 preliminary election the HSPA business that this UE has whether can be supported.When RNC determines at least to exist the HSPA business that a carrier wave k ' supports this UE to have on carrier wave k, continue to perform step 803.Each carrier wave of the HSPA business that UE can be supported to have on carrier wave k determined by said method is the determined pre-selected carriers of this step.Step 803 will be further processed based on these pre-selected carriers.
Step 803, according to parameter sets, the interference power that on the pre-selected carriers of obtaining step 802 gained, the power of each channel of UE causes co-frequency neighbor cell.
With reference to the associated description of above-described embodiment two, three, four, five and six, can know which parameter is the parameter sets that UE or NodeB reports comprise.
If UE has the ability to measure obtain the interference power of each carrier wave in community outside carrier wave k at each down channel, and when these interference powers being reported RNC, namely also comprise each carrier wave in community outside carrier wave k in the parameter sets that RNC receives when the interference power of each down channel, each channel of the UE in above-mentioned " interference power that on the pre-selected carriers of obtaining step 802 gained, the power of each channel of UE causes co-frequency neighbor cell " comprises: each up channel of UE and each down channel; If UE does not have ability measurement to obtain the interference power of each carrier wave in community outside carrier wave k at each down channel, namely do not comprise each carrier wave in community outside carrier wave k in the parameter sets that RNC receives when the interference power of each down channel, each channel of above-mentioned UE only includes: each up channel of UE.
The power that whether there is each channel of UE in the pre-selected carriers of step 804, determining step 802 gained does not exceed the pre-selected carriers of co-channel interference threshold value to the interference power that co-frequency neighbor cell is caused.If existed, perform step 805; If otherwise the power of each channel of UE all exceedes co-channel interference threshold value to the interference that co-frequency neighbor cell is caused on pre-selected carriers, just perform step 806.
The object of this step is for determining that the power of each channel of UE does not exceed the pre-selected carriers of co-channel interference threshold value to the interference power that co-frequency neighbor cell is caused.
For certain pre-selected carriers, the power of each channel of UE does not exceed co-channel interference threshold value to the interference power that co-frequency neighbor cell is caused, and shows that UE can switch on this pre-selected carriers; If exceed, show that UE can not switch on this pre-selected carriers.
Step 805, switch to UE in the pre-selected carriers of step 804 gained a pre-selected carriers on, and the carrier switch request received to be disposed.
Step 806, judge the times N that reconvicts that switches between major-minor carrier wave hOwhether equal 0; If N hO=0, perform step 807; Otherwise, if reconvict times N hObe not equal to 0, start the timer TimerHO that reconvicts switched between major-minor carrier wave, and perform step 808.
It should be noted that, when first time performs step 806, the times N that reconvicts switched between major-minor carrier wave hOequal the pre-configured positive integer being greater than 0.
The carrier switch request received is disposed by step 807, RNC, terminates the handoff procedure between major-minor carrier wave;
Step 808, judge that whether the timer TimerHO that reconvicts switched between major-minor carrier wave is overtime.The timer TimerHO that reconvicts switched between major-minor carrier wave is not overtime, continues to judge;
When step 809, the timer TimerHO that reconvicts switched between major-minor carrier wave are overtime, by the times N that reconvicts switched between major-minor carrier wave hOsubtract one; And return the process that step 801 starts a new round.
Above-mentioned parameter N hOall configuring to UE with timer TimerHO, after UE is triggered and reports request, is N in length hOtimerHO+d1+d2 (N hO+ 1), in the time of+d3, UE no longer will report handover request.Here, d1 represent that the request that UE reports extract by RNC the required time; D2 represents that RNC performs the time required for one-time detection process; D3 represent RNC send to the switching command of UE extract to by UE the required time.These three parameters are configured to UE by RNC.
After NodeB is triggered and reports request, be N in length hOtimerHO+c1+d2 (N hO+ 1), in the time of+c3, NodeB no longer will report handover request.Here, c1 represent that the request that NodeB reports extract by RNC the required time; D2 represents that RNC performs the time required for one-time detection process; C3 represent RNC send to the switching command of UE extract to by NodeB the required time.These three parameters are configured to NodeB by RNC.
It should be noted that, each pre-selected carriers that step 804 can also be obtained in above-mentioned steps 805 carries out prioritization.In step 805, can the carrier wave that priority is the highest be selected, UE is switched on this carrier wave.
With reference to the situation comprising trigger condition about the parameter sets reported of above-described embodiment three, four and six.When trigger condition be Doppler shift or path loss time, if the Doppler shift of UE on the occasion of or path loss successively decreases time, the carrier wave k at UE place is main carrier, then in each pre-selected carriers determined in step 804, prioritizing selection auxiliary carrier wave, is switched to this carrier wave by UE.When there is multiple auxiliary carrier wave, select an auxiliary carrier wave arbitrarily; Or, these auxiliary carrier waves are carried out prioritization, select the carrier wave that priority is the highest, UE is switched on this carrier wave.
If the Doppler shift of UE is negative value or path loss when increasing progressively, the carrier wave k at UE place is auxiliary carrier wave, then, in each pre-selected carriers determined in step 804, select main carrier, UE is switched to this main carrier.When not comprising main carrier in each pre-selected carriers that step 804 is determined, select an auxiliary carrier wave arbitrarily; Or, these auxiliary carrier waves are carried out prioritization, select the carrier wave that priority is the highest, UE is switched on this carrier wave.That is, need here to consider and above-described embodiment three, four or six corresponding trigger conditions.
To each pre-selected carriers determined in step 804, to when wherein each auxiliary carrier wave carries out prioritization, can sort according to the following two kinds method:
First method:
To any one auxiliary carrier wave that step 804 is determined, ask all channels that UE on this carrier wave has to the maximum of the interference power that adjacent cell causes.The carrier wave priority of each auxiliary carrier wave is determined according to the order that this maximum is ascending.The interference power of the channel that the interference power that the auxiliary carrier wave that priority is the highest causes adjacent cell is maximum is minimum in all auxiliary carrier waves.The interference power of the channel that the interference power that the auxiliary carrier wave that priority is minimum causes adjacent cell is maximum is maximum in all auxiliary carrier waves.
For the UE of the interference power of each each descending time slot of carrier wave in capable reporting subdistrict, all channels that in above-mentioned " ask all channels that UE on this carrier wave has to the maximum of the interference power that adjacent cell causes ", UE has on any one auxiliary carrier wave comprise following three class channels.
(1) each DPCH of having at this carrier wave of UE;
(2) have the UE of HSDPA business, this all channel also comprises: HS-SCCH and HS-SICH;
(3) have the UE of HSUPA business, this all channel also comprises: E-AGCH and E-HICH.
For the UE of interference power not having each each descending time slot of carrier wave in capability reporting community, all channels that this UE has on any one auxiliary carrier wave are only made up of the up channel in above-mentioned three class channels.
Second method:
The interference power sum that all channels that on any one auxiliary carrier wave that calculation procedure 804 is determined, UE has cause adjacent cell.The carrier wave priority of each auxiliary carrier wave is determined according to the order that this and value are ascending.All channels that on the carrier wave that priority is the highest, UE has are minimum in all auxiliary carrier waves to the interference power sum that adjacent cell causes.All channels that on the carrier wave that priority is minimum, UE has are maximum in all auxiliary carrier waves to the interference power sum that adjacent cell causes.
In above-mentioned second method, all channels had on any one carrier wave for the UE of the interference power of each each descending time slot of carrier wave in capable reporting subdistrict, this UE are made up of above-mentioned three class channels.For the UE of interference power not having each each descending time slot of carrier wave in capability reporting community, all channels that this UE has on any one carrier wave are only made up of the up channel in above-mentioned three class channels.
When UE has one group of channel u on this carrier wave, the channel selecting interference power maximum from this group channel participates in the read group total in the sequence of above-mentioned carrier wave.Such as, on any one carrier wave k ', the channel u that UE has is HS-SICH, and the HS-SICH set distributing to UE comprises a more than HS-SICH, can calculate the interference power that each HS-SICH that carrier wave k ' above distributes to UE causes co-frequency neighbor cell respectively.When the interference power sum that all channels calculating this UE on carrier wave k ' cause co-frequency neighbor cell, in the HS-SICH set distributing to UE, participate in read group total to the HS-SICH that co-frequency neighbor cell causes interference power maximum, other HS-SICH in the HS-SICH set distributing to UE do not participate in read group total.
Introduce the implementation method of step 803 below.Particularly, step 803 according to parameter sets, the interference power that on the pre-selected carriers of obtaining step 802 gained, the power of each channel of UE causes co-frequency neighbor cell.
RNC will store C/I (carrier/interface ratio) index or the SNR index of any one channel u of UE.This C/I index expression only has when the received power of this channel u and the ratio of interference power are not less than this C/I index, and the quality of reception of this channel just meets the demands.This SNR index expression only has when the SNR of channel u is not less than this SNR index, and the quality of reception of this channel just meets the demands.
The interference power of each ascending time slot on each carrier wave in the community that RNC can report according to the C/I index of each up channel of UE or SNR index and NODE B, calculate by the open loop transmit power of any one up channel u of UE on the carrier wave selected, and then the power of this channel to the interference that adjacent cell causes can be calculated.Determined by open-loop power control method that according to the interference power of a up channel place time slot, the C/I index of this channel or SNR index the method for the open loop transmit power of this up channel refers to existing document.
The interference power of each descending time slot on each carrier wave in the community that RNC can report according to the C/I index of each down channel of UE or SNR index and UE, calculate by the Initial Trans of any one channel u of UE on the carrier wave selected, and then the power of this channel to the interference that adjacent cell causes can be calculated.Determined by open-loop power control method that according to the interference power of a down channel place time slot, the C/I index of this channel or SNR index the method for the Initial Trans of this down channel refers to existing document.
If the parameter sets reporting RNC comprises: the path loss of each community that the path loss of each carrier wave outside the intercarrier k of community and the co-frequency neighbor cell list of each carrier wave comprise.
Further, if carrier wave k ' is by any one carrier wave in the carrier wave selected in step 802; If the upper up channel u of carrier wave k ' is distributed in time slot t by RNC; If in C (k ') individual community, the path loss of the individual community of c ' is L (k ', c ') in the co-frequency cell list of carrier wave k '.
With P (k ', u) represent the upper time slot t up channel u of carrier wave k ' determined by open-loop power control method according to the upper uplink interference power of time slot t of carrier wave k ' and the C/I index of up channel u or SNR index open loop transmit power P (k ', u).
Then comprise in the parameter sets reporting RNC: during the path loss of each community that the path loss of each carrier wave outside the intercarrier k of community and the co-frequency neighbor cell list of each carrier wave comprise, step 803 can adopt one of the following two kinds method, estimates that this is gone up this up channel u to the power of the interference that co-frequency neighbor cell is caused by the carrier wave k ' selected.
First method: the interference power estimating up channel u according to the following formula, the method calculates the interference power that this up channel causes nearest co-frequency neighbor cell:
P I ( k ′ , u ) = P ( k ′ , u ) - min c ′ = 1,2 , . . . . . . , C ′ ( k ′ ) { L ( k ′ , c ′ ) }
Second method: the interference power estimating up channel u according to the following formula, the method estimates the interference power sum that this up channel causes each co-frequency neighbor cell:
P I ( k ′ , u ) = Σ c ′ = 1 C ( k ′ ) ( P ( k ′ , u ) - L ( k ′ , c ′ ) )
When the interference power of each carrier wave in UE has the ability reporting subdistrict at each descending time slot, also need to assess the interference power that this UE causes homogeneous-frequency adjacent-domain at any one down channel u of carrier wave k '.
When channel u is down channel, with P (k ', u) represent the down initial transmitting power of the upper descending interference power of time slot t of carrier wave k ' and the C/I index of channel u that RNC reports according to UE or the upper time slot t channel u of carrier wave k ' that SNR index is determined by open-loop power control method.
Then comprise in the parameter sets reporting RNC: during the path loss of each community that the path loss of each carrier wave outside the intercarrier k of community and the co-frequency neighbor cell list of each carrier wave comprise, step 803 can adopt one of the following two kinds method, estimates that this is gone up this down channel u to the power of the interference that co-frequency neighbor cell is caused by the carrier wave k ' selected.
First method: the interference power estimating down channel u according to the following formula:
P I ( k ′ , u ) = P ( k ′ , u ) - L - min c ′ = 1,2 , . . . . . . , C ′ ( k ′ ) { L ( k ′ , c ′ ) }
Second method: the interference estimating down channel u according to the following formula:
P I ( k ′ , u ) = Σ c ′ = 1 C ( k ′ ) ( P ( k ′ , u ) - L - L ( k ′ , c ′ ) )
When UE does not report the interference power of each carrier wave at each descending time slot, if the interference power that UE each up channel on carrier wave k ' causes co-frequency neighbor cell is all lower than co-channel interference threshold value, then UE can be switched on this carrier wave.That is: to any one up channel u of UE on carrier wave k ', if when the interference that causes adjacent cell of arbitrary up channel u is all lower than co-channel interference threshold value, then thought: UE can be switched to this carrier wave k '.Here co-channel interference threshold value comprises initial co-channel interference threshold value and co-channel interference is biased sum.
When UE reports the interference power of each carrier wave at each descending time slot, if the interference power that UE each channel on carrier wave k ' causes adjacent cell is all lower than co-channel interference threshold value, then UE can be switched on this carrier wave.That is: to any one channel u of UE on carrier wave k ', this channel u can be any up channel of UE on carrier wave k ' and arbitrary down channel, if when the interference that this channel causes adjacent cell is lower than co-channel interference threshold value, then thought: UE can be switched to this carrier wave.
When judging whether a channel exceedes co-channel interference threshold value to the interference power that adjacent cell causes, the initial co-channel interference threshold value of the type channel can be set respectively for the up channel of different type or dissimilar down channel and co-channel interference is biased.Also initial co-channel interference threshold value can be set for all up channels or all down channels are unified and co-channel interference is biased.Also can be that the unification of all types of channel arrange initial co-channel interference threshold value and co-channel interference is biased.
It should be noted that, the parameter sets received corresponding to above-described embodiment five and embodiment six, RNC reports RNC by NodeB, and this parameter sets may comprise: the path loss of each carrier wave outside the intercarrier k of community and the SNPL of each carrier wave.Send to the parameter sets of RNC based on above-mentioned NodeB, the concrete grammar of power to the interference power that co-frequency neighbor cell is caused according to each channel of UE on the pre-selected carriers of parameter sets obtaining step 802 gained in step 803 is as follows:
When the SNPL of each carrier wave and this community path loss are reported RNC by NODE B, RNC determines that the upper configuration of any one carrier wave k ' is as follows to the method for channel u to the interference that adjacent cell causes of UE:
If carrier wave k ' upper signal channel u is distributed in time slot t by RNC, and the carrier wave k ' setting NODE B to report goes up the SNPL of UE as SNPL (k ').
When u is up channel, with P (k ', u) represent the open loop transmit power of the upper time slot t channel u of carrier wave k ' determined by open-loop power control method according to the upper uplink interference power of time slot t of carrier wave k ' and the C/I index of channel u, can estimate that upper this channel u of this carrier wave k ' is to the power of the interference that co-frequency neighbor cell is caused according to the following formula.
P I(k′，u)＝P(k′，u)-L-SNPL(k′)
When channel u is down channel, if UE has the ability to measure to obtain in community each carrier wave in the interference power of each descending time slot, and when these interference powers being reported RNC, with P (k ', u) represent that RNC goes up the descending interference power of time slot t according to the carrier wave k ' that UE reports and the C/I index of channel u goes up the down initial transmitting power of time slot t channel u by the carrier wave k ' that open-loop power control method is determined, RNC needs to adopt following formula to estimate that on this carrier wave, this channel u is to the power of the interference that co-frequency neighbor cell is caused.
P I(k′，u)＝P(k′，u)-2L-SNPL(k′)
When UE does not report the interference power of each carrier wave at each descending time slot, if the interference power that UE each up channel on carrier wave k ' causes co-frequency neighbor cell is all lower than co-channel interference threshold value, then UE can be switched on this carrier wave.When UE reports the interference power of each carrier wave at each descending time slot, if the interference power that UE each up channel on carrier wave k ' and each down channel cause adjacent cell is all lower than co-channel interference threshold value, then UE can be switched on this carrier wave.
