Abstract
The disclosed method guarantees correctness of configuring E-DCH down going control channel. In the invention, Node B prevents scrambling codes of E-AGCH, E-RGCH, and E-HICH from informing to RNC. If requiring using scrambling codes of E-DCH down going control channel, RNC directly queries scrambling codes corresponding to reference channel of relevant wireless link stored locally so as to stop possibility of misusing scrambling codes transferred from Node B radically. The invention prevents error possible to be introduced by Node B in processing procedure, and in procedure of transferring scrambling codes from Node B to RNC. In addition, reducing information sending to RNC from Node B, the invention raises efficiency of transferring NBAP/RNSAP message correspondingly.
Description
Technical field
The present invention relates to moving communicating field, particularly the dedicated channel of enhancing (EnhancedDedicated Channel is called for short " E-DCH ") radio link configuration technology.
Background technology
Universal mobile telecommunications system (Universal Mobile Telecommunications System, be called for short " UMTS ") be (the European Standards Institute of ETSI European Telecommunications Standards Institute, abbreviation " ETSI ") solution that on global system for mobile communications (Global System for Mobile communication is called for short " GSM ") network foundation, is smoothly transitted into 3G (Third Generation) Moblie that proposes.It is exactly in fact 3-G (Generation Three mobile communication system).
UMTS can be compatible with existing traditional gsm system.Gsm system will be stage by stage to the UMTS transition.GPRS (the General Packet Radio Service that has now released, be called for short " GPRS ") provide connectionless service to the GSM network, the business function and the flexibility of gsm system have been expanded, improved transmission of packet data speed, " the 2.5 generation GSM " mobile communication of being known as.And progressively to 3-G (Generation Three mobile communication system) (UMTS) transition.
The major function of universal mobile telecommunications system grounding wireless access network (UMTS Terrestrial Radio AccessNetwork, be called for short " UTRAN ") comprises RRM, such as the wireless mobile management that continues, RAB, safety management, location service management etc. such as handover managements.
Below with reference to Fig. 1, the formation of UTRAN and the interface between the various piece thereof are illustrated.As shown in Figure 1, in UTRAN, comprise base-station node (Node Base Station is called for short " Node B ") and radio network controller (Radio Network Controller is called for short " RNC ").
Wherein, a Node B comprises one or more sub-districts.Interface between Node B and the RNC is an Iub interface, interface between each RNC is the Iur interface, the interface of RNC and core net is the Iu interface, the Node B that RNC and its are controlled constitutes RNS (Radio Network Subsystem, be called for short " RNS "), see shown in the frame of broken lines among Fig. 1.By Uu interface (not shown), promptly air interface connects for RNS and subscriber equipment (User Equipment is called for short " UE ").
Simply introduce SRNS Serving Radio Network Subsystem (Serving Radio NetworkSubsystem below, abbreviation " SRNS "), service wireless network controller (Serving Radio NetworkController, abbreviation " SRNC "), migration RNS (Drift Radio NetworkSubsystem, abbreviation " DRNS "), migration radio network controller (Drift Radio NetworkController is called for short " DRNC ").Be connected with one of UTRAN for UE, its RNS is called SRNS, and corresponding RNC is called SRNC.When because UE mobile when exceeding the cell coverage area of SRNS, UTRAN allows SRNS by Iur interface and the migration RNS that Radio Resource is provided for this UE (promptly, DRNS) link to each other to come for this UE provides access service, corresponding RNC is called migration DRNC (that is, DRNC).
The chain of command signaling of the Iub of UTRAN and Iur interface is respectively base-station node applying portion (Node-B Application Part, be called for short " NBAP ") and Radio Network Subsystem Application Part (RadioNetwork Sub-system Application Part is called for short " RNSAP ").Their major function is exactly the support of operations such as the foundation/increase/reprovision/deletion to Radio Link.
Wherein, control radio network controller (Controlling Radio Network Controller is called for short " CRNC ") is controlled its Node B that controls by the NBAP signaling, and SRNC then controls DRNS by the RNSAP signaling.
More than the formation of UMTS is illustrated, next the dedicated channel (EnhancedDedicated Channel is called for short " E-DCH ") that strengthens is carried out comparatively detailed description.
E-DCH is called high speed uplink packet again and inserts (High Speed Uplink Packet Access, be called for short " HSUPA "), be third generation partner program (3rd Generation Partnership Project, be called for short " 3GPP ") continue and in Release 5, introduce high speed downlink packet access (High Speed DownlinkPacket Access, be called for short " HSDPA ") afterwards, a kind of wireless enhanced technology of in Release 6, introducing.It supports 10ms TTI and two kinds of patterns of 2ms TTI.
Owing to adopted up fast packet scheduling and rapid mixing self adaptation repeat requests (Hybrid Automatic Repeat Request based on Node B, be called for short " HARQ ") etc. key technology, E-DCH has remarkable advantages such as spectrum efficiency height, uplink speed is fast, propagation delay time is little, thereby more effectively supports grouping data services such as real-time game business, file are uploaded, broadband multimedia services to use.
Introduce the relevant up and down physical channel of E-DCH below respectively.
The uplink physical channel that E-DCH is relevant comprises E-DCH Dedicated Physical Data Channel (the E-DCH Dedicated Physical Data Channel that is used for carrying user data, be called for short " E-DPDCH "), and the E-DCH Dedicated Physical Control Channel (E-DCH Dedicated Physical Control Channel is called for short " E-DPCCH ") that is used to carry the required control information of demodulate reception E-DPDCH.
The down physical channel that E-DCH is relevant is control channel, E-DCH absolute grant channel (the E-DCHAbsolute Grant Channel that comprises the absolute grant order of the E-DCH Serving cell that is used to carry the control uplink transmission resource, be called for short " E-AGCH "), be used to carry E-DCH relative authorization channel (the E-DCH Relative Grant Channel of the relative authorization command of controlling uplink transmission resource, be called for short " E-RGCH "), and be used to carry the E-DCH hybrid automatic repeat request indication channel of confirmation (ACK/NACK) (E-DCH Hybrid ARQ IndicatorChannel is called for short " E-HICH ") of the affirmation of Node B/not.Wherein, relative authorization comprises E-DCH service Radio Link collection (Radio Link Set, the RG order of relative authorization abbreviation " RLS ") (Relative Grant is called for short " RG ") order and the non-service Radio Link of E-DCH (Radio Link is called for short " RL ").
Below, with reference to Fig. 2, further specify the frame structure of above-mentioned 3 kinds of down physical channels.In the middle of them, E-AGCH is that the spreading factor (Spreading Factor is called for short " SF ") of fixed rate is 256 down public common.As shown in Figure 2, E-AGCH channel one frame comprises 15 time slots, per 3 time slots constitute a subframe, as mentioned above, E-DCH supports 10ms TTI and two kinds of patterns of 2ms TTI, wherein, to 2ms TTI pattern, E-DCH absolute grant order at a UE is transmitted by a subframe, to 10ms TTI pattern, is then transmitted by a frame at the E-DCH absolute grant order of a UE.
E-RGCH and E-HICH are DPCH, and speed is fixed (SF=128) and had identical frame structure, as shown in Figure 3.Because E-RGCH and the similitude of E-HICH on frame structure are therefore for the same down channel sign indicating number of these two channel sharings of a UE.
40 bits of E-RGCH and each slot transmission of E-HICH are replied the indication decision by specific signature sequence of UE (signature sequences) and the corresponding relative authorization command/HARQ of this UE, and the signature sequence of different UEs is mutually orthogonal.So although E-RGCH and E-HICH are DPCH, but in fact the E-RGCH of same channel code and E-HICH channel can distribute to a plurality of UE, and different UEs is then replied indication information according to relative authorization command/HARQ that different mutually orthogonal signature sequences is distinguished separately.
A HARQ on the E-HICH under 2ms TTI pattern and the 10ms TTI pattern replys indication and adopts 3 or 12 continuous time slot transmission respectively.
A relative authorization command on the E-RGCH adopts 3,12 or 15 continuous time slot transmission, wherein the RG to E-DCH service RLS orders, relative authorization command under 2ms TTI pattern and the 10ms TTI pattern adopts 3 and 12 continuous time slot transmission respectively, to the RG order of the non-service of E-DCH RL, 2ms TTI pattern and 10ms TTI pattern all adopt 15 continuous time slot transmission.
In the existing NBAP and RNSAP technology relevant with E-DCH, by processes such as Radio Link foundation, Radio Link increase, synchronised radio link reprovision, non-synchronous wireless links reconfiguration can realize the E-DCH Radio Link foundation, increase, reconfigure or operation such as deletion.
Among the NBAP and RNSAP message that above-mentioned these processes relate to, comprise the message of initiating by CRNC and SRNC, and by Node B and the DRNS of correspondence return success/response message gets nowhere.Specifically, the message of CRNC and SRNC initiation comprises:
" RADIO LINK SETUP REQUEST (Radio Link is set up request) " message,
" RADIO LINK ADDITION REQUEST (Radio Link increases request) " message,
" RADIO LINK RECONFIGURATION PREPARE (wireless link reconfigured preparation) " message,
" RADIO LINK RECONFIGURATION REQUEST (wireless link reconfigured request) " message,
The success response message of being returned by Node B and DRNS comprises:
" RADIO LINK SETUP RESPONSE (Radio Link is set up response) " message,
" RADIO LINK ADDITION RESPONSE (Radio Link increases response) " message,
" RADIO LINK RECONFIGURATION READY (wireless link reconfigured ready) " message,
" RADIO LINK RECONFIGURATION RESPONSE (wireless link reconfigured response) " message,
The unsuccessful response message that is returned by Node B and DRNS comprises:
" RADIO LINK SETUP FAILURE (Radio Link is set up failure) " message,
" RADIO LINK ADDITION FAILURE (Radio Link increases failure) " message,
With " RADIO LINK RECONFIGURATION FAILURE (wireless link reconfigured failure) " message.
It is pointed out that therefore relevant with the transmitting and scheduling control of E-DCH Control Parameter is distributed by RNC because Node B independently is responsible for the transmitting and scheduling control of E-DCH, these Control Parameter are controlled by Node B oneself.
For above-mentioned Control Parameter is controlled (RadioResource Control by the Radio Resource between RNC and the UE, abbreviation " RRC ") message sends to UE, except that " RADIO LINKRECONFIGURATION FAILURE " message, success that above-mentioned these Node B and DRNS return and unsuccessful response message have all comprised an information element (Information Element is called for short " IE "): " E-DCH FDD DL Control Channel Information " (being translated into " E-DCHFDD downlink control channel information ").Explanation to this IE is as shown in table 1.This IE is in order to returning the relevant control channel parameter of Node B or DRNS transmitting and scheduling control that distribute and E-DCH to CRNC, and finally returns SRNC, so that be transmitted to UE by SRNC by RRC.
As can be seen from Table 1, this IE comprised with E-AGCH, the E-RGCH of respective wireless link and
The IE of the channel parameter of E-HICH (comprising scrambler and channel code) " E-AGCH AndE-RGCH/E-HICH FDD Scrambling Code " (E-AGCH And E-RGCH/E-HICHFDD scrambler), " E-AGCH Channelisation Code " (E-AGCH channel code), " E-RGCH/E-HICH Channelisation Code " (E-RGCH/E-HICH channel code).

Protocol specification TS25.213 according to 3GPP, the scrambler of the E-RGCH of each sub-district, E-HICH and E-AGCH channel, with basic Common Pilot Channel (the PrimaryCommon Pilot Channel of respective phase reference, be called for short " P-CPICH ") or the scrambler of second Common Pilot Channel (SecondaryCommon Pilot Channel is called for short " S-CPICH ") identical.
Wherein, P-CPICH is the phase reference channel that common channel estimating is used, and S-CPICH then is mainly used in the support beam shaping.
Next S-CPICH beam shaping process is described.
In the prior art, in order to support beam shaping, the usage of phase reference S-CPICH as shown in Figure 4.At first, start back CRNC at Node B and set up the sub-district of this Node B by " CELLSETUP REQUEST " (request is set up in the sub-district) NBAP message according to ability information such as Node B resource situations, if Node B supports beam shaping, CRNC will set up corresponding S-CPICH channel by IE " Secondary CPICHInformaton " the indication Node B of message.
As shown in table 2, IE " Secondary CPICH Information " has comprised and has set up needed all information of S-CPICH channel, comprises channel id (channel number), scrambler, channel code, transmitting power and whether carries out diversity emission etc.
Table 2: the IE " Secondary CPICHInformation " that message " CELL SETUP REQUEST " is comprised
Simultaneously, also comprise " Cell Portion Information " (sub-district lobe information) in " CELL SETUP REQUEST " message, as shown in table 3, the effect of this IE is the ID of sub-district lobe and corresponding S-CPICH are associated, thereby is that each sub-district lobe assignment respective phase is with reference to S-CPICH.
Table 3: the IE " Cell PortionInformation " that message " CELL SETUP REQUEST " is comprised
| IE/Group Name (information element/group name claims) | Presence (attribute occurring) | Range (scope) | IE Type and Reference (information element and reference) | Semantics Description (semantic description) | Criticality (severity) | Assigned Criticality (severity of appointment) |

| ＞Maximum Transmission Power for Cell Portion (sub-district lobe maximum transmission power) | M (essential) | Maximum Transmission Power 9.2.1.40 (maximum transmission power 9.2.1.40) | - |
Still as shown in Figure 4, Node B is responsible for carrying out the measurement relevant with beam shaping, comprise reception total wideband power (Received total wide band power) as sub-district lobe (cell Portion), the emission carrier power of sub-district lobe public-measurements such as (Transmitted carrier power), and at signal-to-jamming ratio (the Signal to Interference Ratio of specific radio link, abbreviation " SIR ") measurement waits special measurement, and the measurement report that passes through NBAP is given CRNC with measurement report, in addition, Node B also will measure the SIR of UE at each sub-district lobe when UE initially inserts, and the id information of the sub-district lobe that SIR is the highest (being best sub-district lobe) is by Iub FP (Frame Protocol, Frame Protocol) Random Access Channel (Random Access CHannel, abbreviation " RACH ") Frame is reported to CRNC, wherein, the sub-district lobe is meant the specific geographical area in the sub-district of implementing to measure for beam shaping.
Therefore, CRNC utilizes the measurement of Node B can obtain the information of the best sub-district lobe of UE, thereby is the phase reference S-CPICH of this best cell lobe correspondence of the corresponding Radio Link assignment of this UE.
As seen, the phase reference S-CPICH that Radio Link adopted is CRNC according to the measurement of Node B and is definite, and as mentioned above, protocol specification TS25.213 according to 3GPP, the scrambler of the E-RGCH of each sub-district, E-HICH and E-AGCH channel is identical with reference to the scrambler of P-CPICH or S-CPICH with respective phase, therefore, in fact Node B can not independently select the scrambler of E-RGCH, E-HICH and E-AGCH channel, and the scrambler of E-RGCH, E-HICH and E-AGCH channel is determined by CRNC.
At present, among the IE " RLInformation " (wireless link information) of NBAP message " RADIO LINK SETUP REQUEST ", comprise following IE:
IE " Primary CPICH Usage For Channel Estimation " (P-CPICH channel estimating usage);
IE " Secondary CPICH Information " (S-CPICH information).
These two IE have clearly indicated the phase reference that this Radio Link adopted.
On the other hand, the IE " RL Information " (wireless link information) in the NBAP message " RADIO LINK RECONFIGURATION PREPARE " comprises following IE:
IE " Primary CPICH Usage For Channel Estimation " (P-CPICH channel estimating usage);
IE " Secondary CPICH Information Change " (change of S-CPICH information).
Thereby the phase reference that allows the reprovision Radio Link to be adopted.
On the other hand, for RNSAP, because SRNC is not the CRNC of UE and the Radio Resource of not responsible distribution DRNS, therefore the pairing phase reference of Radio Link of this UE that provides by DRNS is distributed by DRNC and returns SRNC.
In this case, RNSAP all comprises following IE in the IE " RLInformation Response " of return messages " RADIO LINKSETUP RESPONSE " that Radio Link is set up process and " RADIO LINK SETUP FAILURE ":
IE " Primary CPICH Usage For Channel Estimation " (P-CPICH channel estimating usage);
IE " Secondary CPICH Information " (S-CPICH information).
IE " RL Information Response " (wireless link information response) in the RNSAP synchronised radio link reprovision process return messages " RADIO LINKRECONFIGURATION READY " has also comprised following IE simultaneously:
IE " Primary CPICH Usage For Channel Estimation " (P-CPICH channel estimating usage);
IE " Secondary CPICH Information Change " (change of S-CPICH information).
In actual applications, there is following problem in above-mentioned technology.
In the IE " E-DCHFDD DL Control Channel Information " (E-DCH FDD downlink control channel information) of the response message of NBAP and RNSAP and wireless links operation related news, the scrambler that returns E-AGCH, E-RGCH and E-HICH by IE " E-AGCH And E-RGCH and E-HICH FDD Scrambling Code " is irrational.
Cause the main cause of this situation to be, on the one hand for NBAP, the scrambler Node B of E-AGCH, E-RGCH and E-HICH can not independently select and be distributed by RNC, then Node B returns the mistake that this IE may cause the scrambler distribution of E-AGCH, E-RGCH and E-HICH, also increased the useless message content of NBAP and RNSAP, the correctness of Radio Link down control channel configuration can't be protected, thereby produces potential problem.On the other hand for RNSAP, since the scrambler of E-AGCH, E-RGCH and E-HICH is identical with reference to the scrambler of P-CPICH or S-CPICH with respective phase, and the phase reference information of respective wireless link has offered SRNC with response message, and the scrambler that then returns E-AGCH, E-RGCH and E-HICH in response message simultaneously is fully unnecessary and unnecessary.
