When said receiving terminal is the base station; In order further to improve the performance that UE utilizes the target uplink multiple access modes to communicate; Said receiving terminal can also send it to transmitting terminal and be used to switch to the physical layer parameter of target uplink multiple access modes before the preset time arrive (being before receiving terminal is carried out handover operation).
Uplink multiple access modes in the embodiment of the invention also can be called uplink transmission mode.
To combine accompanying drawing that the concrete implementation of the embodiment of the invention in actual application carried out detailed explanation below.
If the LTE-Advanced system supports multiple uplink multiple access modes, then possibly there is the switching between the uplink multiple access modes.Below each application implementation example will describe the handoff procedure of uplink multiple access modes in the LTE-Advanced system in detail.
Application implementation example one
In application implementation example one of the present invention, handoff request is initiated in base station (in embodiments of the present invention, claiming that the base station in the LTE-Advanced system is eNodeB+), and its concrete processing procedure is as shown in Figure 1, can comprise following operation:
11, eNodeB+ sends uplink multiple access modes handoff request message or switching command message to UE;
12, UE returns the uplink multiple access modes switching response message to eNodeB+;
13, switch if desired, then eNodeB+ and UE carry out handover operation simultaneously.
Wherein, In order to guarantee that eNodeB+ and UE carry out handover operation simultaneously; ENodeB+ can be provided with the switching time started of uplink multiple access modes in said uplink multiple access modes handoff request message or switching command message, the said switching time started specifically can be represented with combination of System Frame Number, subframe numbers or System Frame Number and subframe numbers or the like.If UE confirms to carry out the switching of uplink multiple access modes, then inform eNodeB+ through the switching response message of said uplink multiple access modes, eNodeB+ and UE all carry out the handover operation of uplink multiple access modes when the said switching time started arrives.If UE informs that through said uplink multiple access modes switching response message eNodeB+ does not switch, then eNodeB+ and UE still use original uplink multiple access modes.
In addition, also can specifically can be through timer control handover operation; When UE inserts switching response message at the said uplink multi-address of transmission; If affirmation need be switched, then start timer, and when the timer timing finishes, carry out the handover operation of uplink multiple access modes; If eNodeB+ then receive said uplink multi-address when inserting switching response message affirmation need switch; Then start timer; And when the timer timing finishes, carry out handover operation, and the timing length of said UE is the summation of timing length and the expection passing time of uplink multi-address access switching response message of the timer of eNodeB+.Perhaps, UE if affirmation need be switched, then starts timer when receiving said uplink multiple access modes handoff request message or switching command message, and when the timer timing finishes, carries out the handover operation of uplink multiple access modes; ENodeB+ then starts timer when sending said uplink multiple access modes handoff request message or switching command message, if affirmation need be switched, then when the timer timing finishes, carry out handover operation, otherwise, stop timer.And the timing length of said eNodeB+ is the summation of expection passing time of timing length and uplink multiple access modes handoff request message or switching command message of the timer of UE.The timer timing duration of said eNodeB+ and UE can be confirmed through agreement in advance.If control the time of implementation, need not to carry in then said uplink multiple access modes handoff request message or the switching command message and switch the time started through timer.
In order further to improve the performance that UE utilizes the target uplink multiple access modes to communicate, the concrete physical layer parameter when eNodeB+ can also portably use the target uplink multiple access modes in said uplink multiple access modes handoff request message or switching command message; Perhaps, also can be before switching the back according to the uplink multiple access modes switching response message affirmation needs of receiving, switching time started arrival, the concrete physical layer parameter of sending said target uplink multiple access modes.
In the invention described above application implementation example one; Uplink multiple access modes handoff request information or switching command message that said eNodeB+ sends can also be carried the pressure indication message; Promptly in said message, add and force to switch designator; Then UE can not need feeding back uplink access mode switching response message, and eNodeB+ promptly confirms and need switch.In addition; A kind of situation that can also exist is; ENodeB+ sends uplink multiple access modes handoff request message/switching command message and shows that promptly needs switch uplink multiple access modes, and at this moment, UE also can not send feedback information; When arriving the preset time, eNodeB+ and UE carry out handover operation simultaneously.
If the handoff request message of said uplink multiple access modes or switching command message are carried the pressure indication message; Or send uplink multiple access modes handoff request message or switching command message promptly shows needs switching uplink multiple access modes; When using timer control during the time of implementation; Concrete operation can be: eNodeB+ starts timer when sending uplink multiple access modes handoff request message or switching command message, carries out handover operation when the timer timing finishes; UE starts timer when receiving said uplink multiple access modes handoff request message or switching command message; When finishing, the timer timing carries out handover operation; Wherein, the timing length of eNodeB+ is the summation that timing length and the uplink multi-address of the timer of UE inserts the expection passing time of handoff request message or switching command message.
Because in the application implementation example one of the present invention; ENodeB+ and UE need carry out through information interactive affirmation carrying out handover operation after the switching of uplink multiple access modes, thus realized mixing under the multiple access pattern between the uplink multiple access modes flexibly, switch fast.In addition, owing to set the switching time started, thus make eNodeB+ and UE to carry out handover operation simultaneously, improved the stability of system's operation.
Application implementation example two
In application implementation example two of the present invention, UE initiates handoff request, and its concrete processing procedure is as shown in Figure 2, can comprise following operation:
21, UE sends uplink multiple access modes handoff request message to eNodeB+;
22, eNodeB+ returns the uplink multiple access modes switching response message to UE;
23, switch if desired, then eNodeB+ and UE carry out handover operation simultaneously.
Wherein, In order to guarantee that eNodeB+ and UE carry out handover operation simultaneously; UE can be provided with the switching time started of uplink multiple access modes in said uplink multiple access modes handoff request message, the said switching time started specifically can be represented with combination of System Frame Number, subframe numbers or System Frame Number and subframe numbers or the like.If eNodeB+ confirms to carry out the switching of uplink multiple access modes, then inform UE through the switching response message of said uplink multiple access modes, eNodeB+ and UE all carry out the handover operation of uplink multiple access modes when the said switching time started arrives.If eNodeB+ informs that through said uplink multiple access modes switching response message UE does not switch, then eNodeB+ and UE still use original uplink multiple access modes.
In addition, also can specifically can be through timer control handover operation; When eNodeB+ inserts switching response message at the said uplink multi-address of transmission; If confirm and to switch, then start timer, and when the timer timing finishes, carry out the handover operation of uplink multiple access modes; If UE then confirms and can switch when said uplink multi-address inserts switching response message receiving; Then start timer; And when the timer timing finishes, carry out handover operation, and the timing length of said eNodeB+ is the summation of timing length and the expection passing time of uplink multi-address access switching response message of the timer of UE.Perhaps, eNodeB+ if confirm and can switch, then starts timer receiving said uplink multi-address when inserting handoff request message, and when the timer timing finishes the handover operation of execution uplink multiple access modes; UE then starts timer when the said uplink multi-address of transmission inserts handoff request message, if confirm and can switch, then when the timer timing finishes, carry out handover operation, otherwise, stop timer.And the timing length of said UE is the summation that timing length and the uplink multi-address of the timer of eNodeB+ inserts the expection passing time that switches message.The timer timing duration of said eNodeB+ and UE can be confirmed through agreement in advance.If control the time of implementation through timer, then said uplink multi-address inserts to need not to carry in the handoff request message and switches the time started.
In order further to improve the performance that UE utilizes the target uplink multiple access modes to communicate, the concrete physical layer parameter when eNodeB+ can also portably use the target uplink multiple access modes in said uplink multiple access modes switching response message; Perhaps, also can be after transmission uplink multiple access modes switching response message be confirmed to switch, before the switching time started arrives, the concrete physical layer parameter of sending said target uplink multiple access modes.
Because in the application implementation example two of the present invention; ENodeB+ and UE need carry out through information interactive affirmation carrying out handover operation after the switching of uplink multiple access modes, thus realized mixing under the multiple access pattern between the uplink multiple access modes flexibly, switch fast.In addition, owing to set the switching time started, thus make eNodeB+ and UE to carry out handover operation simultaneously, improved the stability of system's operation.
Application implementation example three
In application implementation example three of the present invention, initiate the switching message of uplink multiple access modes by eNodeB+, and said message is included in the RRC connection reconfiguration message.Concrete processing procedure is as shown in Figure 3, can comprise following operation:
31, eNodeB+ sends RRC connection reconfiguration message to UE; And connect increase uplink multiple access modes handover information in the reconfiguration message at said RRC; This uplink multiple access modes handover information is used for to the handoff request of UE initiation uplink multiple access modes; Optional, can also connect the reason that the uplink multiple access modes switching is set in the reconfiguration message at said RRC;
32, UE receives said RRC connection reconfiguration message; And the uplink transmission mode of indicating according to said uplink multiple access modes handover information judges whether to carry out the switching of uplink transmission mode; If can; Then connect to eNodeB+ feedback RRC and reshuffle completion message, said RRC connects to reshuffle to accomplish and carries feedback information in the message and show and can carry out the switching of uplink transmission mode, otherwise; To eNodeB+ feedback RRC connection re-establishment request message, carry handover information or uplink multiple access modes handoff failure information that refusal is carried out uplink transmission mode in the said RRC connection re-establishment request message;
Completion message is reshuffled in connection if 33 eNodeB+ receive RRC, and then eNodeB+ and UE carry out the handover operation of uplink multiple access modes simultaneously; If eNodeB+ receives RRC connection re-establishment request message; And carry refusal in this RRC connection re-establishment request message and carry out the uplink multiple access modes handover information; Perhaps uplink multiple access modes handoff failure information, then eNoedB and UE still use original uplink multiple access modes.
In order to guarantee that eNodeB+ and UE carry out handover operation simultaneously; ENodeB+ can connect the switching time started that carry uplink multiple access modes in the reconfiguration message at said RRC, and the said switching time started specifically can be represented with combination of System Frame Number, subframe numbers or System Frame Number and subframe numbers or the like.If UE confirms to carry out the switching of uplink multiple access modes, then eNodeB+ and UE all carry out the handover operation of uplink multiple access modes when the said switching time started arrives.In addition; Can specifically can be that eNodeB+ starts timer through timer control handover operation when the said RRC of transmission connects reconfiguration message also; If confirm and to switch, then, the timer timing carries out the handover operation of uplink multiple access modes when finishing; Otherwise, stop timer.UE then receiving said RRC when connecting reconfiguration message, if affirmations need be switched, then starts timer, and when the timer timing of UE finishes the execution handover operation, otherwise do not start timer.And the timing length of said eNodeB+ is the timing length of the timer of UE is connected the expection passing time of reconfiguration message with RRC a summation.In addition, can also be, eNodeB+ connects and reshuffles when accomplishing message receiving said RRC, if confirm and can switch, then starts timer, and when the timer timing finishes the handover operation of execution uplink multiple access modes; UE is then when completion message is reshuffled in the said RRC connection of transmission; Need switch if confirm; Then start timer; And when the timer timing of UE finishes, carry out handover operation, and the timing length of said UE is the timing length of the timer of eNodeB+ is connected the expection passing time of reconfiguration message with RRC a summation.
In order further to improve the performance that UE utilizes the target uplink multiple access modes to communicate, the concrete physical layer parameter when eNodeB+ can also portably use the target uplink multiple access modes in said RRC connection reconfiguration message; Perhaps, also can the RRC that receives connect reshuffle accomplish message after, switch the time started arrive before or before the timer timing end, the concrete physical layer parameter of sending said target uplink multiple access modes.
In the invention described above application implementation example three, the RRC that said eNodeB+ sends connects in the reconfiguration message can also carry designator, and the uplink multiple access modes that indication UE carries out by force switches, and then UE can not feed back RRC and connects and reshuffle completion message.In addition, can also be when eNodeB+ sends RRC connection reconfiguration message and in said message, carries the indication message of uplink multiple access modes, to show that promptly UE need carry out the switching of uplink multiple access modes.
Because in the embodiment of the invention three; Being included in RRC about the message of switching uplink multiple access modes between eNodeB+ and the UE connects in the related news of reshuffling; Thereby reduced the message transmission between eNodeB+ and the UE, and then shortened switching time, improved system works efficient.
Application implementation example four
In application implementation example four of the present invention, initiate the switching message of uplink multiple access modes by UE, and said message is included in the RRC connection re-establishment request message.Concrete processing procedure is as shown in Figure 4, can comprise following operation:
