The method comprises the following steps that: a wireless network controller sends a secondary carrier state control condition for indicating to allow or forbid to activate/deactivate the secondary carrier to a node B; the node B judges whether operation indicated by the secondary carrier state control condition is the same as operation indicated by a secondary carrier state control order or not; if so, the secondary carrier state control order is sent to the terminal; and if not, the secondary carrier state control order is forbidden to be sent. With the adoption of the method and the system provided by the invention, the flexibility configured to the carrier by the network is improved by controlling the node B through an RNC (Radio Network Controller).
Description
Technical field
The present invention relates to possess the wireless communication system or the network of multicarrier characteristics, relate in particular to a kind of method and system that the auxilliary carrier wave of multicarrier network activates deexcitation control of carrying out.
Background technology
At first, provide the abstract characteristics that possess multicarrier characteristics system or network, as follows: between certain communication period network element A and network element B,, disposed a plurality of carrier waves in order to increase the needs of data transmission rate.The signal of network element A sends network element B to through the individual carrier wave of N (N＞1), and the signal of network element B sends network element A to through the individual carrier wave of M (M＞1) simultaneously.In N the carrier wave of network element A; If certain carrier wave is responsible for transmitting the signal of all or part of carrier wave of control network element A; Perhaps be responsible for the signal of all or part of carrier wave of transmission control network element B; Perhaps by certain specific relation constraint, this carrier wave is defined as the main carrier of network element A to B, and the carrier wave outside this main carrier is defined as the auxilliary carrier wave of network element A to B.In like manner; In M the carrier wave of network element B; If certain carrier wave is responsible for transmitting the signal of all or part of carrier wave of control network element B, perhaps be responsible for the signal of all or part of carrier wave of transmission control network element A, perhaps by certain specific relation constraint; This carrier wave is defined as the main carrier of network element B to A, and the carrier wave outside this main carrier is defined as the auxilliary carrier wave of network element B to A.Be without loss of generality, suppose that A is a upstream network element, B is a downstream network element, and then network element A is defined as downlink transfer to the transmission of B, and network element B is defined as uplink to the transmission of A.Thereby A is defined as descending carrier to the carrier wave of B; A is defined as the downlink main carrier to carry of A to B to the main carrier of B; A is defined as the descending auxilliary carrier wave of A to B to the auxilliary carrier wave of B; B is defined as up-link carrier to the carrier wave of A, and B is defined as the up main carrier of B to A to the main carrier of A, and B is defined as the upstream auxiliary carriers of B to A to the auxilliary carrier wave of A.Serve B1 in multi-carrier wireless communications system or the network of a plurality of B (for example comprising B1, B2, B3 etc.) at single A, B2, B3 have the up main carrier of different B to A, though identical A to B1, B2, the downlink main carrier to carry of B3 also maybe be different.
List the characteristics of the HSPA+ multicarrier network of several 3GPP definition below.
In the definition of 3GPP; The up-downgoing carrier wave is always paired with each other; Duplex frequency distance is clear and definite, that is to say: when the carrier wave of the some directions of up-downgoing confirms that when frequency F (i), the carrier wave of another direction is also just confirmed at frequency F (j) by pair relationhip so; Main carrier is corresponding with main carrier, and auxilliary carrier wave is corresponding with auxilliary carrier wave.More particularly: up main carrier and downlink main carrier to carry match and use, and promptly main dedicated channel (E-DCH) Serving cell that strengthens is identical with main shared high speed data channels (HS-DSCH) Serving cell; Upstream auxiliary carriers and a certain descending auxilliary carrier wave pairing are used, and promptly auxilliary E-DCH Serving cell is identical with a certain auxilliary HS-DSCH Serving cell.The zone of representing the up-downgoing main carrier to serve with the sub-district on the main carrier face among this paper, the zone of the auxilliary carrier service of up-downgoing is represented in the sub-district on the auxilliary carrier wave face.
3GPP Rel8 agreement has been introduced the notion that two carrier wave high-speed downlink packet insert; Be called for short DC-HSDPA; 2 descending carriers (DL carrier) have been disposed between upstream network element Node B (NodeB) and the downstream network element UE; Wherein be defined as downlink main carrier to carry (DL anchorcarrier) with the descending carrier that High-Speed Dedicated Physical Control Channel (HS-DPCCH) up main carrier of living in (UL anchor carrier) matches mutually; Another descending carrier is defined as descending auxilliary carrier wave (DL secondary carrier) under the state that 2 descending carriers activate simultaneously; NodeB can transmit two data on the HS-DSCH transmission channel simultaneously, so downlink data rate is the twice of single carrier high speed downlink packet access technology (SC-HSDPA) approximately just.For DC-HSDPA, face linchpin in NodeB sector has two sub-districts on the carrier wave face, and data up-downgoing high-speed transfer is arranged in the sub-district on the main carrier face, and in the sub-district on the auxilliary carrier wave face, has only the data downstream high-speed transfer.Shown in accompanying drawing 1, UE is operated in sub-district Cell0-C and the sub-district Cell1-C on the auxilliary carrier wave face the inside on the main carrier face, data up-downgoing high-speed transfer is arranged in the Cell0-C and has only the data downstream high-speed transfer in the Cell1-C.
3GPP Rel-9 agreement has further been introduced two carrier wave High Speed Uplink Packet again and has been inserted, and abbreviates DC-HSUPA as.On the basis of the existing two carrier wave configurations of DC-HSDPA, up main carrier and upstream auxiliary carriers have further been disposed between downstream network element UE and the upstream network element NodeB.Under the state that 2 up-link carriers activate simultaneously, UE can transmit two data on the E-DCH transmission channel simultaneously, so uplink data rate is the twice of single carrier high-speed uplink packet access technology (SC-HSUPA) approximately just.For DC-HSUPA, face linchpin in NodeB sector has two sub-districts on the carrier wave face, and data up-downgoing high-speed transfer is arranged in the sub-district on the main carrier face, in the sub-district on the auxilliary carrier wave face, data up-downgoing high-speed transfer is arranged also.Shown in accompanying drawing 2, UE is operated in sub-district Cell0-C and the inside of the sub-district Cell1-C on the auxilliary carrier wave face on the main carrier face.Data up-downgoing high-speed transfer is arranged in the Cell0-C, and data up-downgoing high-speed transfer is also arranged in the Cell1-C.
3GPP Rel10 agreement along before two carrier wave thinkings further introduced four carrier wave high speed downlink packet access technologies (4C-HSDPA) again, promptly the descending carrier maximum number expands 4 configuration (notes: descending carrier number can certainly for 3 being 3C-HSDPA) to.(notes: also can be the basis of DC-HSDPA existing two carrier wave configurations on) downstream network element UE and upstream network element NodeB between further disposing two additional descending auxilliary carrier waves on the basis of the existing two carrier wave configurations of DC-HSUPA this moment.Under the state that 4 descending carriers activate simultaneously, NodeB can transmit four data on the HS-DSCH transmission channel simultaneously, so downlink data rate just approximately is four times of single carrier high speed downlink packet access technology (SC-HSDPA).Meanwhile, under the state that 2 up-link carriers also activate simultaneously, UE can transmit two data on the E-DCH transmission channel simultaneously, so uplink data rate is the twice of single carrier high-speed uplink packet access technology (SC-HSUPA) approximately just.For 4C-HSDPA, face linchpin in NodeB sector has 4 sub-districts on the carrier wave face.In the sub-district on the main carrier face, data up-downgoing high-speed transfer is arranged; In the sub-district on the auxilliary carrier wave face, the data downstream high-speed transfer is arranged; If on a certain auxilliary carrier wave face upstream auxiliary carriers is arranged, corresponding also have a data uplink high-speed transfer.As attach shown in 3, UE is operated in the sub-district Cell0-C on the main carrier face, the sub-district Cell1-C on the auxilliary carrier wave face 1, the sub-district Cell2-C on the auxilliary carrier wave face 2, the sub-district Cell3-C the inside on the auxilliary carrier wave face 3.Cell0-C; Data up-downgoing high-speed transfer is arranged in the Cell1-C; And Cell2-C, (annotate: the dimension as DC-HSUPA extends, following 4C-HSUPA technology to have only the data downstream high-speed transfer in the Cell3-C; Further disposed two additional upstream auxiliary carriers between downstream network element UE and the upstream network element NodeB, can realize in the sub-district on all major-minor carrier wave faces data up-downgoing high-speed transfer being arranged all).
Above-mentioned or following any HSPA+ multi-transceiver technology no matter, the single-carrier technology before the Rel8, the notion that has all increased descending auxilliary carrier wave and/or upstream auxiliary carriers is used to improve data rate.Because the UE up-downgoing really needs the dynamic change property of data quantity transmitted; The perhaps variability of the residing radio condition of UE; Perhaps network is from the allotment of load balancing, capacity, other purposes such as energy-conservation; The network side base station NodeB can activate or deexcitation the auxilliary carrier wave of the up-downgoing of UE through the order among the down physical channel HS-SCCH (High-Speed Shared Control Channel) dynamically.
The 3GPP agreement is stipulated at present; At network RNC is the initialization moment of UE configuration/reprovision multicarrier; The initialization default conditions of descending auxilliary carrier wave activate; And the initialization default conditions of upstream auxiliary carriers are non-activation, and the state of activation of the auxilliary carrier wave of up-downgoing afterwards is then fully by the local decision of base station NodeB.Shown in accompanying drawing 4; Comprise among the NodeB that (specifically being arranged in resource management module) is used to indicate auxilliary carrier wave to activate or the auxilliary Carrier State judging module of deexcitation perhaps is called auxilliary carrier wave activation deexcitation decision device (Secondary Carrier Act/deact Decider), this module output activates the court verdict of deexcitation to some or a plurality of auxilliary carrier waves.As indicated above, the condition that triggers auxilliary carrier wave activation deexcitation has a lot, and these trigger conditions are usually comprehensively adjudicated through this module, produce a comprehensive court verdict.In this module possibly be logic and algorithm, the algorithm of logic OR, perhaps other various complicated algorithm.The NodeB of different manufacturers can have the different module algorithm to realize.
At present among the 3GPP; All trigger conditions that auxilliary carrier wave activates the deexcitation judgement all come from NodeB inside; This no doubt helps NodeB and makes rapidly reaction timely according to the up-downgoing data traffic of eating dishes without rice or wine between the situation and the network terminal; But also introduced some restrictions, promptly RNC can't be some conditionings that possibly influence auxilliary carrier wave activation deexcitation in the NodeB decision device.Such as: the downlink data that the UE that has need receive from network side has the obvious periodic characteristic; The descending free time that does not receive data is crossed the wait thresholding of descending auxilliary carrier wave deexcitation; But data volume is very big in the descending time of reception, needs descending auxilliary carrier wave to activate and participates in.At this time, if network uses traditional descending auxilliary carrier wave to activate the deexcitation decision mechanism, then auxilliary carrier wave possibly again and again closed switch to be opened.Each auxilliary carrier wave closes the process of opening will bring many unfavorable factors, as causes consume lock in time, and HS-DPCCH physical feedback channel feedback information feedback is reset, and many radio frequencies of UE receive link participation activity and cause power consumption many or the like.
