Technical field
The present invention relates to the communications field, in particular to the sending method and the Node B of a kind of High-Speed Shared Control Channel (High Speed Shared Control Channel abbreviates HS-SCCH as) order.
Background technology
High-speed packet inserts evolution (High Speed Packet Access Evolved, abbreviate HSPA+ as) in increased a lot of new characteristics, for example, enhanced service cell change (Enhanced Serving Cell Change, abbreviate E-SCC as), two carrier waves (Dual Carrier, abbreviate DC as), the continuity grouping inserts (Continuous Packet Connectivity, abbreviate CPC as) in discontinuous transmission (Discontinuous Transmission, abbreviate DTX as)/technology such as discontinuous reception (Discontinuous Receive abbreviates DRX as) and HS-SCCH.
Initial high-speed packet inserts (High Speed Packet Access abbreviates HSPA as) and is mainly used in the data service of doing one's best.CPC and enhancing forward dedicated grouped channels (Enhanced Forwarding Dedicated Packet Channel among the R7, abbreviate Enhanced F-DPCH as) introducing, can improve the capacity of speech business and reduce subscriber equipment (User Equipment, abbreviate UE as) power consumption, making speech business be positioned at HSPA becomes the focus that operator pays close attention to.
When speech business is positioned at HSPA, because dedicated channel (Dedicated Channel, abbreviate DCH as) carry out soft handover, therefore Radio Resource is controlled (Radio Resource Control, abbreviating RRC as) signaling can transmit reliably by the mode that SRB is positioned at DCH, but because DCH has taken a large amount of sign indicating number resources, to cause IP phone (Voice over IP, abbreviate VoIP as)/call session (CaU Session, abbreviate CS as) be positioned at the reduction that high speed downlink packet inserts (High Speed Downlink Packet Access abbreviates HSDPA as) capacity.
In order to improve the capacity of speech business, reasonable method is that SRB is positioned at HSDPA.But the cutting off rate during cell change has very high requirement to service disruption rate and service in speech business.The Serving cell of existing R5 changes process, when adopting SRB to be positioned at HSDPA, cause call drop easily, reason is that the signaling that is used for the Serving cell change among the R5 all is to send at the source Serving cell, and this moment under some intensive urban area circumstances, source Serving cell signal quality may sharply descend.In order to guarantee to be positioned at speech business speech quality and the reliability on the HSDPA, must the HSDPA Serving cell change process among the R5 be strengthened.Therefore, propose Serving cell change process among the R8 again and strengthen work item E-SCC, that is, send HS-SCCH by Target cell and order to UE, UE carries out the sub-district when receiving from the HS-SCCH order of E-SCC and switches.

Preferably, after UE sent the HS-SCCH order, Node B judged whether there be residue HS-SCCH code channel and the power resource that is not used for sending to UE the HS-SCCH order in HS-SCCH code channel of reserving and power resource at HS-SCCH code channel that Node B use to be reserved and power resource; If judged result is for being, then Node B uses residue HS-SCCH code channel and power resource to send business datum to other UE.
In this preferred embodiment, send business datum, can avoid the interface-free resources waste as far as possible, promote service feature by utilizing residue HS-SCCH code channel and power resource.
The present invention also provides two preferred embodiments, combines the technical scheme of above-mentioned a plurality of preferred embodiments, describes in detail below in conjunction with Fig. 2 and Fig. 3.
Fig. 2 is the flow chart according to the HS-SCCH command scheduling algorithm of the embodiment of the invention, as shown in Figure 2, comprises that following step S202 is to step S208.
Step S202: for HS-SCCH code channel and power resource are reserved in the HS-SCCH order.
Step S204:, consider to have different prioritizations from different angles for the ordering of HS-SCCH order User Priority.
Step S206: utilize HS-SCCH code channel and the power resource order user scheduling high reserved to priority, after scheduling is finished, if code channel and power resource residue are arranged, then high order user scheduling to next priority, and the like.
Step S208: if after order user scheduling was finished, the HS-SCCH code channel and the power resource of reservation had residue, remaining code channel and power resource can be used for data service.
In the embodiment of the invention, be HS-SCCH order preset code-channel and power resource, mainly be to be higher than the priority that sends data all the time owing to send the professional priority of HS-SCCH order, as certain Transmission Time Interval (Transmission Time Interval, abbreviate TTI as) when a plurality of UE of appearance need send order, order is professional with the professional transmission of blocking data, cause interface-free resources waste and may cause some to qos requirement than higher data service decreased performance, so need reserve to the code channel and the power resource of HS-SCCH order.When the code channel of HS-SCCH order and power resource have residue, also can be used for data service.
According to the sensitiveness of time delay and the importance of systematic function are considered that important more priority is high more.Here the principle of importance is the normal operation that at first will guarantee UE or system, secondly is the performance that improves UE and system.The dispatching priority order of various command, the E-SCC command prioritization is the highest to be because when switching in the sub-district, if Target cell can not in time send HS-SCCH and order to UE, the rapid decline of cell-of-origin performance will be caused and Target cell can not be switched to, may cause the UE call drop, and speech business requires relatively strictness to cutting off rate.Priority for DTX/DRX deexcitation business is taken second place, because DTX/DRX deexcitation business occurs in the network abnormality, if untimely withdrawing from will cause network performance to worsen.DTX/DRX activates with the HS-SCCH-Less operation and DC activates and deexcitation mainly is in order to improve the performance of system.DTX/DRX activates with the HS-SCCH-Less operation and mainly tends to real time business, to delay sensitive, and two carrier waves mainly are at non-real-time service, and are lower to delay requirement, activate the operation with HS-SCCH-Less so the priority of the activation of DC and deexcitation is lower than DTX/DRX.In addition because the order of the HS-SCCH among the CPC can be simultaneously to DTX/TRX and HS-SCCH-Less activation and deexcitation, and the order of auxilliary carrier wave activation and deexcitation and E-SCCH can only be used separately, so during prioritization below, when if UE is in DTX/DRX activation and deexcitation and HS-SCCH-Less activation simultaneously with deexcitation, if this UE is scheduled, then send the order of DTX/DRX and HS-SCCH-Less simultaneously.
Fig. 3 is the flow chart according to the HS-SCCH order User Priority algorithm of the embodiment of the invention, as shown in Figure 3, and according to the sensitiveness of time delay and the importance of systematic function are considered that it comprises that following step S302 is to step S312.
Step S302: judge whether to need to send the UE of E-SCC order,, forward step S304 to if do not have.If have, select these UE to be combined as the A group, judge in the A group whether the UE that needs re-transmission is arranged, need the UE that retransmits to be classified as the A1 group, new biography UE is classified as the A2 group.To the ordering of A group User Priority, the priority of A1 group UE is higher than the A2 group, in A1 and A2 group inside respectively according to the stand-by period to prioritization, the stand-by period is long more, priority is high more.Forward step S304 to if there is the user to remain.
Whether step S304: judging has the UE that needs to send the DTX/DRX deexcitation, if do not have, forward step S306 in the remaining users.If have, select these UE group to be the B group, judge whether need the UE that retransmits in the B group, the UE that needs to retransmit is classified as B1 and organizes, and new biography UE is classified as B2 and organizes.To the ordering of B group User Priority, the priority of B1 group is higher than the B2 group, B1 and B2 group inside respectively according to the stand-by period to prioritization, the stand-by period is long more, priority is high more.
Step S306: whether the user who judges the B group has the UE that needs to send DTX/DRX activation and HS-SCCH less operation, if do not have, forwards step S308 to.If have, these users' priority if be scheduled, then sends the HS-SCCH order that the DTX/DRX deexcitation activates with DTX/DRX or HS-SCCH less operation combines according to the prioritization among the B.
Step S308: whether need send DTX/DRX activate and HS-SCCH less operate UE, if do not have, forward step S310 to if judging to have in the remaining users.If have, select these UE groups to be the C group, judge in the C group whether the UE that needs to retransmit the HS-SCCH order is arranged, need the UE that retransmits to be classified as the C1 group, the UE of new biography HS-SCCH order is the C2 group, and the priority of C1 group is higher than the C2 group, C1 and C2 group inside respectively according to the stand-by period to prioritization, stand-by period is long more, and priority is high more.Forward step S310 to if there is the user to remain.
Step S310: remaining users is judged whether to need the auxilliary Serving cell of transmission to activate and the UE of the HS-SCCH order of deexcitation,, go to step S312 if do not have.If have, select these UE groups to be the D group, judge in the D group whether the UE that needs to retransmit the HS-SCCH order is arranged, need the UE that retransmits to be classified as the D1 group, the UE of new biography HS-SCCH order is the D2 group, and the priority of D1 group is higher than the D2 group, D1 and D2 group inside respectively according to the stand-by period to prioritization, stand-by period is long more, and priority is high more.
Step S312: to all prioritizations that need send HS-SCCH order user, priority orders is A1, A2, B1, B2, C1, C2, D1, D2.Each UE group internal condition stand-by period ordering, the stand-by period is long more, and priority is high more.
