Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer; To combine the accompanying drawing in the embodiment of the invention below; Technical scheme in the embodiment of the invention is carried out clear, intactly description; Obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
Division for TA group has two kinds of technology: a kind of is that the TA that is called the UE level organizes with the sub-district of the UE identical or different TA of the division group according to the TA value of the current sub-district of this UE.Another kind is the TA group of cell-level, and it is that the TA group is divided in different sub-districts that situation such as specifically can Network Basedly dispose is come, the sub-district that belongs to a TA group this moment fix and specifically this sub-district be that to belong to which UE irrelevant.
The flow chart of the update processing method of the TA value that Fig. 1 provides for the embodiment of the invention one.The executive agent of the update processing method of the TA value of present embodiment is base station, for example eNB.As shown in Figure 1, the update processing method of the TA value of present embodiment specifically can comprise the steps:
Step 100, when the TA value of the TA of UE group needs adjustment, from TA organizes, select the sub-district;
Particularly, variation has taken place in the TA value that goes out the TA group of UE when identification of base stations, and when needing adjustment, the sub-district is selected in the base station from this TA group.On the sub-district of selecting, send TA order (Command) then to UE.Carry adjustment information among this TA Command.Like this, when UE receives this TA order through this sub-district, just can therefrom get access to adjustment information, and revise the TA value of the TA group under this sub-district, with the effective renewal and the maintenance of the TA value that realizes TA among the UE is organized according to adjustment information.Particularly, in the internal memory of UE, can store the TA information table of this UE, can include the sign of each TA group of this UE, the sign and the corresponding information such as TA value of each TA group of each TA group corresponding district in this TA information table.UE can send upward signal based on the relevant information in this TA information table.Here UE specifically can revise the TA value of the TA group in this TA information table that is stored in the internal memory based on adjustment information, sends upward signal for UE is follow-up based on this TA value, to guarantee that upward signal can arrive in the base station synchronously.
Because the sub-district in the TA group is corresponding identical TA value respectively, so this sub-district can be any sub-district in this TA group.Preferably, in order to improve the success rate that UE receives TA Command, best this selecteed sub-district of conduct, sub-district of signal in all sub-districts in the TA group can be selected in the base station.
In the prior art, when UE in use is moved, when the TA value of the TA group that UE is corresponding changes, base station use medium access control (Medium Access Control; Hereinafter to be referred as MAC) TA command notice UE change TA value in the order, in TA Command, carrying needs the TA group id and the TA value information of modification revised, changes the TA value of this TA group id correspondence with notice UE.But in TA command, carry the expense that the TA group id that needs modification can increase signaling.And the UE under the transmission mode of the legacy version of R8/9 also can't discern this TA group id, causes the backwards compatibility of this scheme relatively poor.
The update processing method of the TA value of present embodiment when the TA value of the TA of UE group needs adjustment, is selected the sub-district from the TA group; On the sub-district, send regularly order in advance, carry adjustment information in this TA order to UE; The TA value according to the TA group under the adjustment information modification sub-district for UE is used in this TA order.With compare in the prior art, when the TA value is upgraded effectively, can save the expense of signaling effectively.And the technical scheme of employing present embodiment, need not do any improvement to UE, backwards compatibility is better, and can safeguard effectively the TA value among the UE.
Need to prove, also can only comprise a unique sub-district in the TA group in the foregoing description, the corresponding TA value in each sub-district this moment.This moment, the sub-district was the unique sub-district that comprises in this TA group.
Need to prove that adjustment information comprises that the deviant or the TA of the TA value of TA group organize adjusted TA value in the foregoing description.When adjustment information was the deviant of TA value of TA group, UE can be based on the deviant and TA group original T A value of the TA value of TA group, get access to this TA organize should correspondence after adjusting the TA value.When adjustment information is TA when organizing adjusted TA value, UE just can directly get access to TA and organize adjusted TA value.
Need to prove that the TA group of the UE in the technical scheme of the foregoing description comprises the TA group of UE level or also can be the TA group of cell-level.
The flow chart of the update processing method of the TA value that Fig. 2 provides for the embodiment of the invention two.The executive agent of the update processing method of the TA value of present embodiment is base station, for example eNB.As shown in Figure 2, the update processing method of the TA value of present embodiment specifically can comprise the steps:
Step 200, send configuration messages, carry the sign of the sub-district of increase in this configuration messages to UE; This configuration messages is for be designated the sub-district that UE configuration increase of UE according to the sub-district that increases;
The sign of the TA group under the sub-district of step 201, broadcasting increase in the system message of the sub-district that increases; Obtain the sign of this TA group for UE; And, obtain the TA value that the TA under the sub-district of increase organizes according to the sign of the TA that has the disposed group of the sign of this TA group and UE.
Particularly; When the base station is received quality report information that UE sends or other reasons decision for this UE increase sub-district; Configuration messages is sent to UE in the base station; The second corresponding cell setting of sign with the request UE sub-district that will increase is the sub-district of this UE, makes that the sub-district of this increase can be that this UE serves.Except scheme according to prior art; In UE, be provided with outside some configuration parameters about the sub-district of this increase; UE also need write down the sign of the sub-district of this increase particularly, increases the sign of the sub-district of this increase of record in the TA information table of for example in the internal memory of UE, storing.Like this, UE can know that just the sub-district of this increase can be this UE service.That is to say that UE can receive the message that send the base station based on being identified on the corresponding district of sub-district of the increase of record, perhaps on the sign corresponding district of the sub-district of this increase, send upward signal.
Also broadcast simultaneously the sign of the TA group under the sub-district of this increase in the system message of base station in the sub-district that increases.Like this, when UE can receiving system message, and therefrom get access to the sign of the TA group under the sub-district of this increase.UE can be according to the group of the TA under the sub-district that has added of TA group id and this UE then, obtains the TA value of the TA group under the sub-district of increase.
For example the sign of the TA group that disposed of the sign of the group of the TA under the sub-district that increases and this UE is identical, explain that the sub-district that increases newly belongs to this UE and disposed this TA group, and it is identical to increase the TA value that the TA value that the affiliated TA of sub-district organizes and the TA that this UE has disposed organize.When the sign that all TA that disposed as sign and this UE of the TA of the sub-district that increases group organize is inequality, explain that the sub-district of this increase belongs to a new TA group, this moment, UE can initiate to insert at random (Random Access on the sub-district of this increase; Hereinafter to be referred as RACH) process, with the TA value of the corresponding TA group in the sub-district that obtains this increase to base station requests.
Configuration messages in the present embodiment specifically can be the control of the Radio Resource in the LTE system (Radio Resource Control; Hereinafter to be referred as RRC) the connection reconfiguration message.
In the present embodiment, can first execution in step 200 execution in step 201 again, also can first execution in step 201 execution in step 200 again.
The update processing method of the TA value of present embodiment; When increasing the sub-district for UE; Send configuration messages to UE, and the sign of the group of the TA under the sub-district that broadcasting increases in the system message that increases the sub-district, obtain the sign of the TA group under the sub-district of this increase for UE; And according to the TA group under the sign of the group of the TA under the sub-district that increases and the sub-district that has been set to this UE, obtain the TA value that the TA under the sub-district of increase organizes.Adopt the technical scheme of present embodiment, can realize effectively the TA value of the sub-district that increases newly is upgraded, be very easy to follow-up upward signal and can arrive the base station according to this TA value transmission.
The RRC that also can be employed in newly-increased sub-district in the prior art connects and reshuffles the TA group id that carries in the sub-district under this newly-increased sub-district, but adopts this scheme can increase the expense of signaling.The technical scheme of present embodiment is compared with this existing scheme, can save signaling consumption effectively.
The flow chart of the update processing method of the TA value that Fig. 3 provides for the embodiment of the invention three.The executive agent of the update processing method of the TA value of present embodiment is base station, for example eNB.As shown in Figure 3, the update processing method of the TA value of present embodiment specifically can comprise:
Step 300, confirm that the TA group under the sub-district of UE is revised as the 2nd TA group by TA group;
Step 301, send modify request messages to UE, this modify request messages according to revising solicited message, is revised as the 2nd TA group with the group of the TA under this sub-district by TA group for UE; And obtain the TA value of the 2nd TA group.
The application scenarios of present embodiment can be the TA group of UE level for the TA group of UE.
The update processing method of the TA value of present embodiment can realize effectively when the TA of UE group changes, and in time, exactly the TA value of the UE after changing is upgraded, is very easy to follow-up upward signal according to this TA value transmission and can arrives the base station.
Need to prove that the base station is sent to UE and revised solicited message in the foregoing description, carry the sign of sub-district and the sign of the group of the 2nd TA under this sub-district in this modification solicited message.Perhaps the modification solicited message can also directly be sent to UE in the base station on this sub-district, and need not carry the sign of sub-district this moment in this modification solicited message, can only carry the sign of affiliated the 2nd TA group in this sub-district.Modification solicited message in the present embodiment is to supply UE that the group of the TA under the sub-district is revised as the 2nd TA group by TA group.Particularly, the sign that UE can be through will being stored in the TA group under this sub-district in the TA information table in the UE internal memory is revised as the sign of the 2nd TA group by the sign of TA group, for UE the TA group information of this sub-district is managed.
The TA group that for example identifies a sub-district as UE changes; Such as, a sub-district belongs to TA group x, becomes through repeater without repeater before; Then TA can not be shared with other sub-districts of same TA group before in this sub-district, thereby becomes and belong to a new TA group y by belonging to TA group x.This moment, UE sent the quality testing report to the base station, and modify request messages is sent to UE in the base station, also can be called TA group change command particularly.In the LTE system, can order or RRC message to the MAC that UE sends for the base station, be used to notify the UE TA situation of change of group.The base station can be the sign that carries this sub-district and the sign of the new TA group y under this sub-district in the TA group change command that UE sends particularly, and TA group this sub-district is corresponding for UE is updated to TA group Y.Perhaps TA group change command is specifically sent to UE in the base station on this sub-district; Can only carry the sign of the affiliated new TA group y in this sub-district this moment among the TAgroup change command; Identification renewal for the UE TA group that this sub-district in the TA information table in the internal memory is corresponding is the sign of TA group Y, with realization the corresponding TA group in this sub-district is upgraded.
The flow chart of the update processing method of the TA value that Fig. 4 provides for the embodiment of the invention four.As shown in Figure 4, the executive agent of the update processing method of the TA value of present embodiment is UE.The update processing method of the TA value of present embodiment specifically can comprise as follows:
The TA Command that sends on step 400, the sub-district of reception base station in the TA group; Carry adjustment information among this TACommand;
