Abstract
The method is utilied in the FCS procedure of the HSDPA to transfer the synchronizing information of the PDU send state between the subzones along the IP transmission route between base stations. When the new subzone enters into the activation set, the main subzone transmits PDU, which is unrecognized in the MAC-hs, to the new subzone through route between the base stations directly. Meanwhile, the RNC also transmits the new PDU to the new subzone. The synzhonrizing procedure between the new sobzone and the other subzones is speeded up since PDU in two routes are transmitted to the new subzone at same time. Thus, the invention raises the continuity of data transmission in FCS procedure, speeds up the synchronizing procedure of the PDU queue and the procedure of filling data as well as reduce the signaling overhead between RNC and Node B.
Description
Technical field
The present invention relates to the fast cell selection method in the access of wireless communication system high-speed downstream bag.
Background technology
FCS (fast cell selection) technology that HSDPA (access of high-speed downstream bag) adopts is to replace the centralized PDU formation of existing RNC (radio network controller) with distributed PDU (protocol Data Unit) formation in each sub-district.In downlink transmission process, RNC is handed down to all sub-districts that are in the Active Set simultaneously with the PDU data, selected to receive data from a best sub-district of performance by UE (subscriber equipment) then, and other sub-district remains on suspended state to the downlink transfer of this UE.When the main plot substituted, when promptly UE had selected another sub-district to receive data, current main plot was hung up, and selected new sub-district begins down-transmitting data.After UE receives the data of main plot transmission, for carrying each TTI (Transmission Time Interval) feedback ACK (affirmation) information of these data.The main plot becomes the affirmation information translation of these TTI the affirmation information of the PDU that corresponding TTI carries.Though the ACK signaling that all sub-districts in the Active Set can both be sent by up channel uppick UE, but which PDU owing to what respectively do not know from the sub-district to encapsulate the pairing TTI of ACK is, so they can't explain this signaling, and can only understand which PDU by the main plot are identified.
The data of passing to UE by new and old sub-district when guaranteeing that the main plot substitutes are continuous, all sub-districts in the Active Set need keep the synchronous of PDU transmit status, promptly, although each has only the main plot to send data and explain the ACK information of returning to UE constantly, but other in the Active Set also needs to grasp at any time the reception condition of PDU from the sub-district, comprise being identified, being retransmitted, and other associated transport parameter.Above-mentioned synchronizing process can be controlled by RNC by network usually, and it gives the confirmation of receipt information of respectively regularly issuing PDU from the sub-district according to the reporting information of UE or main plot.Respectively from the sub-district according to this information adjustment PDU formation separately, make it to be consistent with main plot PDU quene state.
At present preferably RNC to obtain UE be the auxiliary reflection method (NodeB assisted PDU bitmap) of NodeB (wireless base station of broadband CDMA system) to the method for the accepting state of PDU.In this method, the main plot is identified state according to each PDU in the PDU formation, generate a mapping, i.e. bitmap with PDU queue length, every affirmation state of representing a PDU in the PDU formation successively, report RNC with form of message from NodeB then, RNC is transmitted to this mapping message each non-main plot again.Because mapping message need be transmitted through RNC, therefore repeatedly pass through the signaling delay meeting of Iub/Iur (interface between the interface/RNC between RNC and the base station) interface and bring lagging influence synchronously for the sub-district.
For Active Set, if there is new sub-district to add, then new sub-district at first will obtain the PDU formation identical with the main plot, could equally with other sub-district carry out PDU simultaneous operation then.Because the new required PDU data of NodeB issue from RNC, simultaneously because RNC can not determine the PDU quene state in the current main plot, so must be to the information of main plot elder generation's request one " still unacknowledged PDU ".Then, RNC transmits these PDU through new sub-district.Even RNC has backed up the PDU data that are issued to NodeB in the PDU formation in RLC (Radio Link control), so also need to one of main plot request " bitmap of unacknowledged PDU still " information, from the RLC transmit queue, find out these PDU then, they are sent to new sub-district.There is said process as can be known, because the information exchange between the sub-district is all transmitted by RNC, make new cell data filling process need pass through more delay, because the influence of these delays and transmission level, make HARQ (mixing automatic repeat requests), AMC lower floor's transmission parameters such as (adaptive coding and modulating) pass to new sub-district by piggybacking RNC, limited the FCS performance of HSDPA.

Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
In the standard of 3GPP, at UTRAN (UTMS land radio access web, UTMS: introduce the IP transmission universal mobile telecommunications system), data flow is a sign with " UDP (User Datagram Protoco (UDP)) port numbers+IP address " on the Iub interface, promptly comes the data flow on the recognition interface by " purpose IP address ", " purpose udp port number ".Because after RAN (wireless access network) used IP network, each network element all directly hung on the edge router of IP network, for HSDPA, HSDPA FP (the high-speed downstream bag inserts Frame Protocol) agreement is adopted in the direct communication of user's face between the NodeB." the purpose udp port number+purpose IP address " of its data flow distributed by new NodeB, and tells former NodeB by NBAP (broadband CDMA system base station application part) signaling by RNC.NodeB direct communication based on IP transmission provides a more fast way for the information exchange between the NodeB, has brought new possible for solving problems such as the synchronous and new cell data filling of minizone PDU transmit status that above-mentioned HSDPA FCS faces.
For improving the performance of HSDPA FCS, the present invention has adopted following step: the first step, set up the transmission link between the base station under all sub-districts in radio network controller and the Active Set, and base station and all transmission links between the base station under the sub-district under the main plot.
Second step, after main plot and subscriber equipment carry out transfer of data and obtain confirming feedback, with PDU (protocol Data Unit) affirmation state by base station under the described main plot and under the sub-district transmission link between the base station be sent to from the sub-district, adjust the PDU formation of this sub-district from the sub-district according to described PDU affirmation state, and then finish the PDU state synchronized control of minizone.Above-mentioned PDU affirmation state is sent to from the sub-district and can finishes by the PDU quene state synchronization message between the base station.This step is with reference to figure 2, and shown in the figure, in the process of minizone PDU state synchronized, it is synchronous that RNC issues the PDU of NodeB, and the PDU formation that receives in each sub-district all is identical.After main plot and UE have carried out transfer of data and obtained the ACK feedback, the PDU that has been identified in its PDU formation is marked, and PDU is confirmed that state passes to other sub-district by the direct transmission path between the NodeB.
The 3rd step, when new sub-district adds Active Set, owing to there are not the affiliated base station of transmission link and main plot between the base station under radio network controller and the new sub-district and all transmission links between the base station under the sub-district, then at first to set up described transmission link, the main plot by base station under the described main plot and under the sub-district transmission link between the base station unacknowledged PDU is sent to new sub-district, radio network controller issues new PDU by all sub-districts in Active Set of the transmission link between the base station under all sub-districts in radio network controller and the Active Set simultaneously, new sub-district is organized into the two-way PDU that the main plot that receives and radio network controller transmit in the PDU formation of this sub-district, and then finishes the synchronizing process of PDU formation of new sub-district and the PDU formation of other sub-district.This step is with reference to figure 3.Shown in Figure 3, in new cell data filling process, suppose that sub-district 5 is the sub-districts that newly enter Active Set, obtain PDU formation and the state identical in order to make it with the main plot, the main plot still by the general of the path between the NodeB still unacknowledged PDU reach new sub-district.The new sub-district PDU formation that the PDU data that directly transmit from the main plot are formed has kept the synchronous regime of main plot PDU formation naturally, thereby does not need other synchronizing information.And in the main plot when the padding data of new sub-district, RNC can remain unchanged simultaneously that all sub-districts in Active Set issue new PDU.Like this, after new sub-district buffer memory was filled, PDU wherein is actual to be transmitted by two independent paths: 1) main plot, along the new transmission path between the NodeB; 2) RNC, along RNC to the conventional transmission path between the NodeB.
Transmission link described in above-mentioned second step and the 3rd step is IP (IP) link.
In above-mentioned the 3rd step, when new sub-district added Active Set, the described process of setting up transmission link is as described below: suppose that the NodeB under the main plot is NodeB-old, the affiliated NodeB in new sub-district was NodeB-new, and they all belong to same RNC.Like this, 1) when new sub-district enters Active Set, the link under RNC and the new sub-district between the NodeB, i.e. RNC → NodeB-new.2) main plot and under the sub-district direct link between the NodeB, i.e. NodeB-old → NodeB-new.
RNC sends the signaling of " request for building link " to NodeB-new, NodeB-new is RNC and sign of the link assignment between it, simultaneously, NodeB-new also is that (NodeB-old → NodeB-new) distributes a sign for link between itself and the NodeB-old.Then, NodeB-new returns to RNC by the signaling of " link establishment response " with these two signs.So far, the RNC link establishment that goes downwards to NodeB-new is finished.RNC is after receiving " link establishment response " signaling that NodeB-new returns, the chain line that wherein new NodeB is distributed for the link of setting up between the new and old NodeB sends to NodeB-old by the signaling of " request for building link ", NodeB-old also distributes a sign for it to the link between the NodeB-new then, sets up the direct transmission link between two NodeB.
For PDU state synchronized and the new sub-district two-way PDU filling process of controlling the minizone, the present invention also adds the module with " PDU state synchronized controlled function " in the MAC-hs of sub-district.The function that this module shows in the main plot is:
1) in the PDU status synchronizing process, generate " PDU confirms state " message, and to sending from the sub-district; 2) in new cell data filling process, generate " still unacknowledged PDU " message, and to sending from the sub-district;
This module in the function that shows from the sub-district is:
1) in the PDU status synchronizing process, receives " PDU confirms state " information that the main plot is transmitted, and adjust the PDU formation of this sub-district according to this information; 2) in new cell data filling process, receive the two-way PDU that transmits from main plot and RNC, and they are organized in the PDU formation of this sub-district.
The receiving course of above-mentioned two-way PDU is with reference to figure 4.As shown in Figure 4, for new sub-district, come autonomous cell and from the two-way PDU of the RNC arrival that may interlock, the two-way receiving function of PDU synchronization control module is sent in the PDU buffer queue of MAC-hs after with their orderings.In real process, because every road PDU was exactly orderly originally, so can adopt the method that two-way PDU is inserted into PDU formation diverse location, realize the ordering between them apace, that is: new sub-district PDU formation is provided with the position boundary sign of a two-way PDU, after PDU is received by the two-way receiving function one by one, be inserted in respectively before PDU tail of the queue and the position boundary sign, working as PDU like this receives, the PDU buffer queue of MAC-hs is exactly orderly, and is identical with the PDU formation of main plot.
The 4th step, when Active Set is withdrawed from the sub-district, remove with this sub-district under between the base station transmission link and and the main plot under transmission link between the affiliated base station in base station and this sub-district.Suppose that the NodeB under the main plot is NodeB-primary, NodeB is NodeB-secondary under the sub-district, they all belong to same RNC, when withdrawing from from Active Set from the sub-district, RNC will remove two links: the 1) link between NodeB-secondary and the NodeB-primary; 2) link between NodeB-secondary and the RNC.
Demolishing process is: RNC sends the signaling of " link discharges request " to NodeB-secondary, NodeB-secondary discharges the link between itself and the RNC, simultaneously the NodeB-secondary of its distribution and the chain line between the NodeB-primary are returned to RNC by signaling, RNC reinforms NodeB-primary, allows it stop to send " PDU the confirms state " message that keeps synchronous to NodeB-secondary.
In method of the present invention, when needs carry out the main plot replacement, send the sign of selected new main plot by UE all sub-districts in Active Set, this sign is listened in each sub-district, if finding selected sub-district is oneself, then start the down link that is suspended, beginning transmits the PDU data as the main plot.The down link of former main plot changes suspended state into.Because the PDU formation in each sub-district has kept synchronous regime, so the main plot substitutes the not influence of PDU content to being transmitted, UE receives is still continuous PDU data flow.
When substituting in above-mentioned main plot, all need rebulid from the link between sub-district and the new main plot.The NodeB that supposes to substitute under the preceding main plot is NodeB-old, substitutes that NodeB is NodeB-new under the new main plot, back, also has other NodeB-other under the sub-district in addition, and they all belong to same RNC.At first NodeB-old stops to send " PDU the confirms state " message that keeps synchronous to NodeB-other and NodeB-new.Then, for being about to reception, it distributes a new chain line from the information that NodeB-new transmits, after passing to NodeB-newNodeB-new and receive these chain line together with the chain line between itself and the NodeB-other then, discharge the chain line between its original and NodeB-old, can begin then to all " PDU confirms state " message that keep synchronous that send from the sub-district.
The method of the raising HSDPAFCS performance that issues based on NodeB direct communication and two-way PDU of the present invention both had been applicable to the sub-district Active Set in the same RNC, also was applicable to the sub-district Active Set that has covered different RNCs.For the sub-district under the different RNCs control, the efficiency of transmission gain that the direct communication between NodeB brings is bigger.And two-way PDU fills function more can make the PDU unconfirmed of main plot need not so very long path of process " NodeB → RNC → RNC → NodeB ", and directly arrives new sub-district.And, the transmission parameter of minizone HARQ, AMC be not subjected to synchronously yet RNC inner or between influence, this makes versatility of the present invention more obvious.
Be example of the present invention below:
With reference to figure 5.Supposing has a sub-district A (belonging to NodeB-1) in the current FCS process in the Active Set, another sub-district B (belonging to NodeB-2) is entering Active Set.Link between this moment RNC and the NodeB-1 is PATH-0, being designated of its transmission bearer: purpose udp port number (udp port number 1), purpose IP address (NodeB-1IP address).
The RLC PDU quene state of supposing RNC this moment is a state shown in Figure 6, and wherein sequence number is that 0~999 PDU is handed down to NodeB-1, and sequence number is that 1000 later PDU are positioned at send window, but the still following PDU that is handed down to NodeB-1.
Again hypothesis this moment the main plot the MAC-hs buffer memory in the PDU quene state as shown in Figure 7, wherein preceding 600 PDU have sent to UE, and have received that the sign of UE feedback receives successful ACK information.400 PDU in back do not obtain confirming as yet.
After new sub-district B entered Active Set, RNC set up new link a: PATH-1 with NodeB-2 immediately, being designated of its transmission bearer: purpose udp port number (udp port number 2), purpose IP address (NodeB-2 IP address).Simultaneously, NodeB-1 also and NodeB-2 set up direct transmission link between them: PATH-2, being designated of its transmission bearer: purpose udp port number (udp port number 3), purpose IP address (NodeB-2 IP address).
After setting up successfully with the transmission link of new sub-district, main plot A and RNC fill the PDU data to the buffer memory of new sub-district B simultaneously.Main plot A sends the 600th~No. 999 PDU data encapsulation in the formation to sub-district B by " transmitting PDU unconfirmed " function of its " PDU synchronization control function " in HSDPA FP frame; In this process, RNC also may issue new PDU in the window synchronously to sub-district A and sub-district B, and promptly sequence number is 1000~1499 PDU.
Sub-district B receives the PDU data that HSDPA-FP carries by " the two-way receiving function " of its " PDU synchronization control function " from PATH-1 and PATH-2 two paths.Suppose that two-way PDU boundary mark in its buffer queue refers to the position 100, then its PDU of receiving from PATH-1 inserts MAC-hs PDU rear of queue, and will be inserted in from the PDU that PATH-2 receives between the PDU of No. 99 PDU and No. 100 position the formation sub-district B data fill finish after, it with the PDU quene state of sub-district A fully synchronously.
In ensuing process, sub-district A continues to transmit data as the main plot to UE, at certain time intervals after, variation has taken place in its PDU quene state, as: the the 600th~700 and the 710th~750 two section PDU among the last figure successfully obtained the affirmation of UE, with reference to figure 8.This moment, it needed to cross PATH-2 to sub-district B issue " PDU confirms state synchronization ", and this information comprises a mapping (bitmap), total (750-600+1) position, and wherein the 102nd~109 value is 0, other value is 1.
The sub-district receives above-mentioned synchronizing information from PATH-2, confirms mark for the PDU of the relevant position in its PDU formation does, and the PDU formation of two sub-districts has at this moment kept synchronous again.
Suppose that at this moment its wishes sub-district B is replaced by in the main plot along with the moving of UE, then its sends a up signaling that contains sub-district B sign.This message is received simultaneously by sub-district A and sub-district B.Sub-district A finds that the sign of oneself is different with the cell ID that UE selectes, and promptly stops the data distributing to UE; Simultaneously, sub-district B finds own selected, and then the PDU formation head of the queue from it begins to transmit the PDU that is not identified, be in this example sequence number be 701~709 and sequence number greater than 750 PDU.In this process, the PDU data that UE receives are continuous and level and smooth.
