To combine instance that the implementation procedure of the embodiment of the invention is described in detail below.
Preferred embodiment one
UE1 is in connection status through UMTS system access network, UE1 access base station 1 jurisdiction district 1, and base station 1 is administered by RNC.Have identical cell covered 2 by base station 2 administrations with sub-district 1, base station 2 belongs to the LTE system.
In the UMTS system, have Iub interface between RNC and the base station 1.Because RNC possibly implement joint transmission with the base station 2 among the LTE, so has set up new interface between RNC and the base station 2, is used for Data transmission and control signaling.Interface between RNC and the base station 2 is set up can be by operation and maintenance (Operation & Maintenance) server implementation.
UE1 has set up a Data Radio Bearer (Data Radio Bearer abbreviates DRB as), representes with DRB1 here.UE1 hopes to set up DRB2 because new business demand is arranged, yet because the desired transmission rate of DRB2 is higher, the available resources of sub-district 1 have satisfied not the requirement of DRB2.The mode of joint transmission is adopted in the RNC decision, sets up DRB2 through the Radio Resource of sub-district 2, and RNC find that this subscriber equipment has only a cover radio frequency transceiver, so RNC is the multiplexing joint transmission mode of UE1 configuring time division according to the ability information of the UE1 that has obtained.
Fig. 5 is the interaction diagrams according to the joint transmission method of the preferred embodiment of the present invention one, and is as shown in Figure 5, comprises that following step S501 is to step S504.
Step S501; RNC through and base station 2 between the interface foundation request of sending new Data Radio Bearer DRB2 to base station 2; The QoS parameter (Quality of Service) that in this request, comprises DRB2 is so that the rational distributing radio resource in base station 2.RNC considers that UE1 has only a cover radio frequency transceiver; Therefore in the request of setting up, also comprise the time-division information that adopts different access technologies; Specifically can be to indicate the temporal information (or sub-frame information) that UE1 activates in UMTS, and indicate the temporal information (or sub-frame information) that UE1 activates in LTE.
Fig. 6 is the sketch map according to the joint transmission method of the preferred embodiment of the present invention one, and is as shown in Figure 6, and UE1 activationary time in UMTS is 10 milliseconds, and UE1 activationary time in LTE is back to back 10 milliseconds.Need to prove, only explain to descending reception among Fig. 6, in fact also be suitable for for the up transmission of UE.
Need to prove here, realized between RNC and the base station 2 perhaps having known the original position of the other side's radio frames synchronously.
Step S502; After the foundation request of DRB2 is received in base station 2; Be the UE1 Resources allocation; As the Radio Network Temporary Identifier RNTI (Radio Network Temporary Identifier) that distributes needs to monitor, the activationary time information that preservation simultaneously comprises in setting up and asking is so that at this UE1 of suitable time scheduling.Response is returned to RNC in base station 2, comprises the resource parameters of distribution.
After step S503, RNC receive the response of sending base station 2, send dedicated signaling, wherein comprise the resource parameters that base station 2 is distributed for UE1 to UE1, and the temporal information that in two systems, activates.
After step S504, UE1 received the dedicated signaling that RNC sends, using should configuration.UE1 can at first select to keep 10 milliseconds communicating by letter with RNC, communicates by letter with base station 2 maintenances at back to back 10 milliseconds then.Because UE1 has obtained the resource that base station 2 is distributed, can realize the transmission of signaling and data with base station 2.
Need to prove here; After receiving the response of sending base station 2 at RNC, need between RNC and the base station 2 to set up data transmission channel, comprise uplink and downlink about UE1; RNC sends descending packet to base station 2 simultaneously, so that there are enough downlink data transmission base station 2 when communicating by letter with UE1.
So far, UE1 can adopt time-multiplexed mode and UMTS system and LTE system to communicate jointly, respectively the data of the different DRB of transmission in different systems.Network side can effectively be implemented load balancing by this method, can different Data Radio Bearer be directed to the light system of load in real time according to the load of different system.
Present embodiment also has other implementation; In the foundation request of step S501, comprised the time-division information that adopts different access technologies; Base station 2 can be made modification to this in step S502, informs that through return response to RNC RNC consults successful time-division information at last then; Perhaps,
In the foundation request of step S501, do not comprise the time-division information that adopts different access technologies; After request is received in base station 2; Distributed the temporal information that activates in the LTE system; In the response that RNC returns, comprise the temporal information of distribution then, confirm the temporal information that in the UMTS system, activates after RNC receives.
In the present embodiment; UE1 uses time-multiplexed configuration information immediately in step S504; UE1 also can begin to use time-multiplexed configuration information after predefined a period of time, begin to use time-multiplexed configuration information like UE1 in the initial moment of next radio frames (Radio Frame); Perhaps UE1 is to begin to use time-multiplexed configuration information at 0 o'clock at System Frame Number (System Frame Number) next time.
In the present embodiment, UE1 keeps communicating by letter with UMTS, LTE system in step S504 successively, and UE1 also can at first keep communicating by letter with the LTE system, keeps communicating by letter with the UMTS system then.Perhaps in step S504; Only configuration UE 1 time and the cycle in individual system, activated; The time of in the UMTS system, activating like configuration UE 1 is 10 milliseconds, and the cycle is 20 milliseconds, after UE1 receives; Still can keep communicating by letter with base station 2 then as at first keeping communicating by letter among the step S504 with RNC.UE1 is when communicating by letter respectively with the LTE system with the UMTS system; The radio frequency transceiver of UE1 need switch between two frequencies, and this needs extra a period of time, and present embodiment is referred to as the frequency inverted time; The length of frequency inverted time depends on hardware; Agreement can be predesignated the frequency inverted time of a minimum requirements, when UE1 is transformed into another system from a system, needs to consider the influence of this time; Forward the LTE system such as UE1 to from the UMTS system, total time of activating in the LTE system need comprise the frequency inverted time.If the radio frequency processing performance of UE1 is very good, promptly the frequency inverted time does not have influence this change-over time far below 1 millisecond to communicating by letter, and then the influence of this frequency inverted time to communication can be ignored in the terminal when transition between systems.
Need to prove that UE1 only has half the time and RNC to keep communicating by letter in 20 milliseconds cycle, RNC or UE1 can store the data that need transmission, the time Data transmission that can transmit earlier; Perhaps RNC can reshuffle the spreading factor that UE1 uses; As reducing original spreading factor that uses half the; Then RNC or UE1 can utilize 10 milliseconds time to transmit the data that originally need 20 milliseconds of ability transmission; Therefore adopt after the time-multiplexed mode, UE1 can not reduce transmission rate in the UMTS system.
Present embodiment has been described the scene that subscriber equipment has only a cover radio frequency transceiver; In fact for the subscriber equipment that has many cover radio frequency transceivers; Also can adopt the described method of present embodiment,, only can save power consumption with a cover radio frequency transceiver for this type subscriber equipment.
Preferred embodiment two
User equipment (UE) 2 is in connection status through LTE system access network, UE2 access base station 3 jurisdiction districts 3.Base station 4 among the UMTS is administered by RNC.The covering area overlapping of 4 jurisdiction districts 4, base station and sub-district 3.
UE2 has set up a Data Radio Bearer DRB (Data Radio Bearer), representes with DRB1 here.Because the real-time Transmission speed of UE2 is very big, base station 3 does not have enough resources to satisfy UE2, so base station 3 hopes to use the mode of joint transmission to make UE2 can obtain more Radio Resource.
In the UMTS system; (up is HSUPA (High Speed Uplink Packet Access) if subscriber equipment uses the HSPA technology; Descending is HSDPA (High Speed Downlink Packet Access)); The scheduling of subscriber equipment is responsible for by the base station, and the spreading code that uses like subscriber equipment, the time slot that uses spreading code etc. are by base stations control.In the present embodiment, base station 3 hopes that UE2 can use HSPA technology in the UMTS system simultaneously, so has set up interface between base station 3 and the base station 4, is used for control channel and data.Interface between base station 3 and the base station 4 can be by operation and maintenance (Operation & Maintenance) server implementation.
The mode of joint transmission is adopted in base station 3 decisions; For UE2 provides more Radio Resource to satisfy its rate requirement; Base station 3 is according to the ability information of the UE2 that has obtained; Find that this subscriber equipment has only a cover radio frequency transceiver, so base station 3 is the multiplexing joint transmission mode of UE2 configuring time division, its concrete realization flow is:
Step S701, base station 3 through and base station 4 between interface send the joint transmission requests to base station 4, in this request, comprise the QoS parameter (Quality of Service) of DRB1, so that the rational distributing radio resource in base station 4.Base station 3 considers that UE2 has only a cover radio frequency transceiver; Therefore in request, also comprise the time-division information that adopts different access technologies; Specifically can be included in the zero-time that activates in the UMTS system, the time of in the UMTS system, activating (perhaps being called the duration that adopts the HSPA technology) and cycle; Like the duration that to be arranged on the zero-time that activates in the UMTS system be certain absolute time in the request, in the UMTS system, activate is 30 milliseconds, and the cycle is 50 milliseconds.Promptly in the zero-time of correspondence, UE2 adopts the HSPA technology to communicate 30 milliseconds with base station 4, communicates 20 milliseconds (50-30=20) with base station 3 then; Communicate 30 milliseconds with base station 4 once more afterwards, circulation is so always gone down, and stops the mode of joint transmission until base station 3.
Step S702; After request is received in base station 4; Be the UE2 Resources allocation, like the Radio Network Temporary Identifier RNTI (Radio Network Temporary Identifier) that distribution need be monitored, the activationary time information that comprises in the preservation request simultaneously is so that at this UE2 of suitable time scheduling.Response is returned to base station 3 in base station 4, comprises the resource parameters of distribution.
Step S703; After the response of sending base station 4 is received in base station 3; Send dedicated signaling to UE2, wherein comprise the resource parameters that base station 4 is distributed for UE2, and the zero-time that in the UMTS system, activates, time (perhaps being called the duration that adopts HSPA technological) and the cycle in the UMTS system, activated.
After step S704, UE2 received the dedicated signaling of sending base station 3, preserving should configuration.UE2 keeps communicating by letter with base station 4 in time slot corresponding according to the zero-time that comprises in the signaling, 30 milliseconds of duration, in back to back 20 milliseconds, keeps communicating by letter with base station 3 then.Because UE2 has obtained the resource that base station 4 is distributed, can realize the transmission of signaling and data with base station 4.
The time-multiplexed mode that adopts UE2 has realized communicating jointly with UMTS and LTE system, respectively the data of the identical DRB of transmission in different systems.Network side can effectively be implemented load balancing by this method, can the partial data transmission be adjusted in the lighter system of load in real time according to the load of different system.
Need to prove here, receive the response of sending base station 4 in base station 3 after, need to set up data transmission channel between base station 3 and the base station 4 about UE2; Comprise uplink and downlink; Base station 3 is to the part downlink data packet of base station 4 these UE2 of transmission simultaneously, so that there are enough downlink data transmission base station 4 when communicating by letter with UE2, base station 3 needs the function of newly-increased data distribution; Select the partial data bag and send to base station 4, transmit to UE2 through base station 4.UE2 receives the packet that two base stations send over respectively; Need to realize merging; UE2 can multiplexing existing wireless chain control layer (Radio Link Control) the function of merger and reorganization, realize the merging of packet, application layer still can receive complete packet like this.
Present embodiment also has other implementation; As having only the request of joint transmission among the step S701; Do not comprise the time-division information that adopts different access technologies; After request is received in base station 4, in the response of returning to base station 3, be included in the temporal information (comprising zero-time, duration, cycle) that activates in the UMTS system.
Present embodiment has been described the scene of UMTS and the system combined transmission of LTE, and is in fact suitable equally for GERAN system and LTE system or GERAN system and UMTS system.Like scene for GERAN system and the system combined transmission of LTE; Set up interface between the base station in base station controller in the GERAN system and the LTE system; Be used to transmit signaling and data, the base station negotiate of two systems is confirmed the time that subscriber equipment activates, notifying user equipment then in different system; Just can realize time-multiplexed joint transmission method, effectively the load between two systems of balance.
Preferred embodiment three
