In the embodiment of the invention, processing procedure based on transmitting terminal can comprise: the indication message that sends uplink multiple access modes to receiving terminal, the indication message of described uplink multiple access modes is used to refer to the receiving terminal of described indication message and carries out handover operation, it specifically can be the target uplink multiple access modes, the perhaps identifier of target uplink multiple access modes, perhaps switching designator of uplink multiple access modes or the like; When arriving, carries out the default time handover operation.Wherein, described transmitting terminal both can be the base station, also can be UE.
Among the invention described above embodiment, can also comprise the process that judges whether to switch uplink multiple access modes, specifically can be: obtain the feedback information that receiving terminal sends, described feedback information comprises: agree to switch uplink multiple access modes, or refusal switching uplink multiple access modes, or when arrive in the lag time of regulation, resend indication message; Judge according to described feedback information, if the feedback information indication agrees to switch uplink multiple access modes, then judge and to carry out handover operation, and when arriving, switches the default time uplink multiple access modes, if feedback information indication refusal switches uplink multiple access modes, then do not carry out handover operation, if the feedback information indication resends indication message when arrive in the lag time of regulation, then do not carry out handover operation, and resend the indication message of described uplink multiple access modes according to feedback information.
Among the invention described above embodiment, before carrying out handover operation, described transmitting terminal can also send the information of uplink multiple access modes switch reasons to receiving terminal.For example, the information of carrying described uplink multiple access modes switch reasons when sending the indication message of described uplink multiple access modes perhaps sends the information of described uplink multiple access modes switch reasons by other message.
For the assurance system is normal, reliability service, when judgement can be switched uplink multiple access modes, transmitting terminal and receiving terminal need be carried out handover operation simultaneously, and the described default time is exactly in order to control the time of implementation of handover operation, so that realize synchronously.In the embodiment of the invention, determine that with transmitting terminal the operation of described default time correlation specifically can comprise:
Set the time started information of switching, determine to arrive the described default time according to the switching time started information of described setting, in order to realize switching synchronously, transmitting terminal sends to receiving terminal with the switching time started information of described setting, transmitting terminal and receiving terminal are monitored described switching time started information, carry out the switching of uplink multiple access modes if desired,, carry out the handover operation of uplink multiple access modes simultaneously when arriving default switching during the time started;
Perhaps, determine to arrive the described default time according to the switching time started information that the described receiving terminal that receives is sent, transmitting terminal and receiving terminal are monitored described switching time started information, carry out the switching of uplink multiple access modes if desired, when arriving predetermined switching during the time started, carry out the handover operation of uplink multiple access modes simultaneously;
Above-mentioned switching time started information specifically can be represented with the combination of System Frame Number, subframe numbers or System Frame Number and subframe numbers.In addition, if transmitting terminal and receiving terminal have all sent switching time started information, then the switching time started information that can send with an end according to a preconcerted arrangement is as the criterion;

For the assurance system is normal, reliability service, transmitting terminal and receiving terminal need be carried out handover operation simultaneously, so the default time is exactly in order to control the time of implementation of handover operation, so that realize synchronously.In the embodiment of the invention, determine that with receiving terminal described default time arrives relevant operation and specifically can comprise:
Set the time started information of switching, determine to arrive the described default time according to the switching time started information of described setting, in order to realize switching synchronously, receiving terminal sends to transmitting terminal with the switching time started information of described setting, transmitting terminal and receiving terminal are monitored described switching time started information, if can carry out the switching of uplink multiple access modes,, carry out the handover operation of uplink multiple access modes simultaneously when arriving predetermined switching during the time started;

In addition, if carry the information of compulsory execution in the indication message of the described uplink multiple access modes that receives, then described receiving terminal is judged needs execution switching according to this information, and at this moment, receiving terminal also can not send feedback information to transmitting terminal.
Can also be that the indication message that receives uplink multiple access modes shows that then needs switch uplink multiple access modes, at this moment, do not carry the information of compulsory execution in the indication message of described uplink multiple access modes.
Among the invention described above embodiment, send feedback information to transmitting terminal if desired, the mode of then described transmission feedback information specifically can comprise:
In the uplink multiple access modes switching response message, carry described feedback information;

Perhaps,
Utilize the physical layer feedback signaling to send described feedback information.
When described receiving terminal is the base station, in order further to improve the performance that UE utilizes the target uplink multiple access modes to communicate, described receiving terminal can also send the physical layer parameter that it is used to switch to the target uplink multiple access modes to transmitting terminal before the default time arrives (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.
Below in conjunction with accompanying drawing the specific implementation of the embodiment of the invention in actual application is described in detail.
If the LTE-Advanced system supports multiple uplink multiple access modes, then may there be the switching between the uplink multiple access modes.Below each Application Example will describe the handoff procedure of uplink multiple access modes in the LTE-Advanced system in detail.
Application Example one
In Application 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 can comprise following operation as shown in Figure 1:
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 described uplink multiple access modes handoff request message or switching command message, the described 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 determines to carry out the switching of uplink multiple access modes, then inform eNodeB+ by the switching response message of described uplink multiple access modes, eNodeB+ and UE all carry out the handover operation of uplink multiple access modes when the described switching time started arrives.If UE informs that by described 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 control handover operation, specifically can be by timer, when UE inserts switching response message at the described 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 eNodeB+ then confirms and need switch when described uplink multi-address inserts switching response message receiving, then start timer, and carry out handover operation when the timer timing finishes, and the timing length of described 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 confirm and need switch, then starts timer when receiving described uplink multiple access modes handoff request message or switching command message, and carries out the handover operation of uplink multiple access modes when the timer timing finishes; ENodeB+ then starts timer when sending described uplink multiple access modes handoff request message or switching command message, if confirm and need switch, then carry out handover operation when the timer timing finishes, otherwise, stop timer.And the timing length of described eNodeB+ is the summation of the expection passing time of the timing length of timer of UE and uplink multiple access modes handoff request message or switching command message.The timer timing duration of described eNodeB+ and UE can be determined by agreement in advance.If control the time of implementation, need not to carry in then described uplink multiple access modes handoff request message or the switching command message and switch the time started by 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 described uplink multiple access modes handoff request message or switching command message; Perhaps, also can before confirming that according to the uplink multiple access modes switching response message of receiving needs switch back, the arrival of switching time started, send the concrete physical layer parameter of described target uplink multiple access modes.
In the invention described above Application Example one, uplink multiple access modes handoff request information or switching command message that described eNodeB+ sends can also be carried the pressure indication message, promptly in described 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, at this moment, UE also can not send feedback information, when arriving the default time, eNodeB+ and UE carry out handover operation simultaneously.
If the handoff request message of described 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 described 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 timing length of timer of UE and the summation that uplink multi-address inserts the expection passing time of handoff request message or switching command message.
Because in the Application Example one of the present invention, eNodeB+ and UE need carry out by 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 Example two
In Application Example two of the present invention, UE initiates handoff request, and its concrete processing procedure can comprise following operation as shown in Figure 2:
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 described uplink multiple access modes handoff request message, the described 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+ determines to carry out the switching of uplink multiple access modes, then inform UE by the switching response message of described uplink multiple access modes, eNodeB+ and UE all carry out the handover operation of uplink multiple access modes when the described switching time started arrives.If eNodeB+ informs that by described 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 control handover operation, specifically can be by timer, when eNodeB+ inserts switching response message at the described 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 described uplink multi-address inserts switching response message receiving, then start timer, and carry out handover operation when the timer timing finishes, and the timing length of described 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 described 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 described uplink multi-address of transmission inserts handoff request message, if confirm and can switch, then carry out handover operation when the timer timing finishes, otherwise, stop timer.And the timing length of described UE is the timing length of timer of eNodeB+ and the summation that uplink multi-address inserts the expection passing time that switches message.The timer timing duration of described eNodeB+ and UE can be determined by agreement in advance.If control the time of implementation by timer, then described 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 described uplink multiple access modes switching response message; Perhaps, also can after transmission uplink multiple access modes switching response message is confirmed to switch, before the switching time started arrives, send the concrete physical layer parameter of described target uplink multiple access modes.
Because in the Application Example two of the present invention, eNodeB+ and UE need carry out by 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 Example three
In Application Example three of the present invention, initiate the switching message of uplink multiple access modes by eNodeB+, and described message is included in the RRC connection reconfiguration message.Concrete processing procedure can comprise following operation as shown in Figure 3:
31, eNodeB+ sends RRC connection reconfiguration message to UE, and connect increase uplink multiple access modes handover information in the reconfiguration message at described RRC, this uplink multiple access modes handover information is used for to the handoff request of UE initiation uplink multiple access modes, optionally, can also connect the reason that the uplink multiple access modes switching is set in the reconfiguration message at described RRC;
32, UE receives described RRC and connects reconfiguration message, and the uplink transmission mode of indicating according to described uplink multiple access modes handover information judges whether to carry out the switching of uplink transmission mode, if can, then connect to reshuffle and finish message to eNodeB+ feedback RRC, described RRC connects to reshuffle to finish 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 described RRC connection re-establishment request message;
Connect to reshuffle and finish message if 33 eNodeB+ receive RRC, 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 described RRC, and the described 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 determines 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 described switching time started arrives.In addition, also can control handover operation by timer, specifically can be, eNodeB+ starts timer when the described RRC of transmission connects reconfiguration message, if confirm and to switch, then when finishing, the timer timing carries out the handover operation of uplink multiple access modes; Otherwise, stop timer.UE then receiving described RRC when connecting reconfiguration message, if confirm and need switch, then starts timer, and carry out handover operation when the timer timing of UE finishes, otherwise do not start timer.And the timing length of described 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 finishing message receiving described 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 then connects and reshuffles when finishing message sending described RRC, need switch if determine, then start timer, and carry out handover operation when the timer timing of UE finishes, and the timing length of described 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 described RRC connection reconfiguration message; Perhaps, also can the RRC that receives connect reshuffle finish message after, switch the time started arrive before or before the timer timing end, send the concrete physical layer parameter of described target uplink multiple access modes.
In the invention described above Application Example three, the RRC that described 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 to reshuffle and finish message.In addition, can also be when eNodeB+ sends RRC connection reconfiguration message and carry the indication message of uplink multiple access modes in described message, 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 Example four
In Application Example four of the present invention, initiate the switching message of uplink multiple access modes by UE, and described message is included in the RRC connection re-establishment request message.Concrete processing procedure can comprise following operation as shown in Figure 4:
41, UE sends RRC connection re-establishment request message to eNodeB+, and in described RRC connection re-establishment request message, increase the uplink multiple access modes handover information, this uplink multiple access modes handover information is used for to the handoff request of eNodeB+ initiation uplink multiple access modes, optionally, the reason that uplink multiple access modes switches can also be set in described RRC connection re-establishment request message;
42, eNodeB+ receives described RRC connection re-establishment request message, and judge whether to carry out the switching of uplink transmission mode, if of course,, carry feedback message in the described RRC connection re-establishment message and show and to switch uplink transmission mode then to UE feedback RRC connection re-establishment message; If cannot, then to UE feedback RRC connection re-establishment refuse information, carry feedback information in the described RRC connection re-establishment refuse information and show that refusal switches uplink transmission mode, perhaps to UE delay of feedback request message, is set in the described time-delay request message lag time, and notice UE initiates handoff request again when arrive in this lag time;
If 43 UE receive RRC connection re-establishment message, then eNodeB+ and UE carry out the handover operation of uplink multiple access modes simultaneously; Otherwise eNoedB and UE still use original uplink multiple access modes.

63, UE judges whether that according to the uplink multiple access modes handoff response MAC CE PDU of feedback message of receiving or eNodeB+ transmission needs switch uplink multiple access modes, if desired, then eNodeB+ and UE all carry out the handover operation of uplink multiple access modes when the described switching time started arrives.
In order to realize that eNodeB+ and UE carry out handover operation simultaneously, can also control handover operation by timer, specifically can be, can switch if confirm, eNodeB+ starts timer, the handover operation of execution uplink multiple access modes when the timer timing finishes when sending described uplink multiple access modes handoff response MAC CE PDU; UE is then receiving described uplink multi-address when inserting handoff response MAC CE PDU, if affirmation can be switched then be started timer, and carry out handover operation when the timer timing finishes, and the timing length of described eNodeB+ is the summation of timing length and the expection passing time of uplink multi-address access handoff response MAC CE PDU of the timer of UE.
Perhaps, eNodeB+ is receiving described uplink multiple access modes when switching MAC CE PDU, if confirm to switch then start timer, and when the timer timing finishes the handover operation of execution uplink multiple access modes; UE then inserts and starts timer when switching MAC CE PDU sending described uplink multi-address, if confirm and can switch, then carries out handover operation when the timer timing finishes, if affirmation cannot be switched termination timing device then.And the timing length of described UE is the timing length of timer of eNodeB+ and the summation that uplink multi-address inserts the expection passing time that switches MAC CE PDU.
