Description
Technical field
The present invention relates to moving communicating field, particularly the renewal technology of optimum subdistrict.
Background technology
Code division multiple access (Code Division Multiple Access is called for short " CDMA ") technology is a kind of mobile communication technology that designs for requirements such as the desired big capacity of present mobile communication net, high-quality, integrated service, soft handover, international roamings.
CDMA technology, is modulated much larger than the high speed pseudo noise code of signal bandwidth with a bandwidth by certain signal bandwidth information data that has that will need to transmit based on spread spectrum, and the bandwidth of former data-signal is expanded, again through carrier modulation and send.Receiving terminal uses identical pseudo noise code, makes relevant treatment with the broadband signal that receives, and broadband signal is converted to the narrow band signal of prime information data, promptly broadband signal is carried out despreading, thereby realizes information communication.
The cdma mobile communication net is by several technology be combined intos such as spread spectrum, multiple access access, beehive net and channelings, contain a kind of cooperation that frequency domain, time domain and sign indicating number territory three dimensional signal are handled, therefore it to have anti-interference good, the anti-multipath decline, the secret and safe height, same frequency can be reused in a plurality of sub-districts, can do attributes such as trade-off between capacity and the quality.
That is to say,, make that a plurality of users' user terminal (User Equipment is called for short " UE ") can a shared channel by CDMA technology.Network side distributes a sign indicating number sequence that differs from one another for each UE in advance, is called " pseudo-random code sequence ", utilizes the mutually non-interfering characteristic of this sign indicating number sequence, a shared frequency spectrum.Also just because of CDMA adopts spread spectrum, all signals are shared same frequency spectrum, and the signal energy of each UE is dispensed in the whole frequency band scope, and the signal of each UE just becomes noise concerning the UE of this sub-district and other sub-districts like this.Noise jamming is big more, and the user's communications quality is poor more.
In order to guarantee the user's communications quality, need reduce interference from other sub-district/users as far as possible.The soft handover notion has been proposed thus.
So-called soft handover is about to enter new sub-district as UE exactly, when needing with a new base station communication, does not interrupt earlier and the getting in touch of former base station, but sets up its link in new sub-district, waits for entering behind the new sub-district being connected of deletion again and former cell base station fully.Soft handover can only carry out between the CDMA Channel of same frequency.It has played the diversity effect of Traffic Channel at the intersection of two base station overlay areas.Can significantly reduce like this owing to switch the call drop that causes.Because toward the test statistics to analogue system, 90% call drop takes place in handoff procedure on the wireless channel according to this.Realize switching and causing that probability of call reduces greatly after the soft handover, guaranteed the reliability of communication.
Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access, be called for short " WCDMA ") be the cdma system that adopts direct sequence spread spectrum (DSSS) technology, belong to 3G (Third Generation) Moblie (The Third Generation, be called for short " 3G "), it expands to user bandwidth more than 1000 times by spreading code, expands channel width to 5MHz.According to information-theoretical theory, can under the situation of low signal-to-noise ratio very, transmit information reliably like this with same transmission rate, strengthen antijamming capability greatly, realized code division multiple access, can support various user data rate.
In the R5 of WCDMA version, introduced high speed downlink packet access (High SpeedDownlink Packet Access, be called for short " HSDPA "), HSDPA is 3G (Third Generation) Moblie collaborative project tissue (The Third Generation Partnership Project, be called for short " 3GPP ") a kind of new high speed data transfer technology announced, be on satisfying/the asymmetric demand of downstream data traffic and a kind of modulation and demodulation algorithm of proposing.
In order to reach the purpose that improves downlink grouped data speed and reduce time delay, HSDPA has mainly adopted adaptive modulation and coding (Adaptive Modulation and Coding, abbreviation " AMC "), mixed self-adapting repeat requests (Hybrid Automatic Repeat Request is called for short " HARQ ") and fast dispatch technology etc.
Wherein, the fast dispatch technology is being controlled shared resource allocation in the network, has determined the behavior of whole system to a great extent.Reasonably scheduling makes network can reach the highest user data rate and maximum data throughout in each moment, can take into account each user's grade and fairness simultaneously.
The fast dispatch technology generally only allows UE and a sub-district to communicate, and this sub-district is called Serving cell.In order to reduce the interference from other sub-districts as far as possible, Serving cell should be updated on the optimum subdistrict as early as possible, otherwise will be very big from the interference of optimum subdistrict, influences indexs such as the descending throughput of UE, time delay, seriously reduces user's impression, even call drop.
Network side is normally selected optimum subdistrict according to the down-run survey report of UE.Promptly detected the performance of peripheral cell by UE, and report the measured value of measured sub-district to network side, the measurement result that network side reports according to UE is according to certain criterion assessment optimum subdistrict.Wherein, the mode that reports of measurement report has two kinds, comprises periodic report and reporting events.
Periodic report is meant that UE detects the performance of peripheral cell, and according to the fixing cycle to the network side reporting measurement reports, according to the measurement report that receives, carry out the assessment of optimum subdistrict by network side.
Reporting events is meant that network side is issued to UE with the part assessment level, finishes the part evaluation work by UE, and when the sub-district of criterion was satisfied in existence, UE sent event measurement report to network side, according to the event measurement report of receiving, makes corresponding decision-making by network side.
Comparatively speaking, adopt periodic report, its advantage is that the processing of UE side is simple, and network side can be assessed in conjunction with practical application flexibly according to the measurement report that reports; But the data volume that periodic report makes UE report is excessive, takies the processing resource of a large amount of interface-free resources and network side.And the employing event report, the complexity that the UE side realizes has certain increase, but can obviously reduce the data volume of eating dishes without rice or wine and the processing burden of network side.
In the prior art, the main reporting events method that adopts is selected optimum subdistrict, in 3GPP 25.331 agreements, defined 1D incident (optimum subdistrict reported event), when active set cell of measuring as UE or the path loss of inspecting the collection sub-district satisfy formula 1, or the active set cell measured of UE or Common Pilot Channel (the Common Pilot Channel that inspects the collection sub-district, abbreviation " CPICH ") signal to noise ratio (Ec/No) or CPICHRSCP (letter of acceptance number power) are when satisfying formula 2, UE reports the 1D incident, upgrades the optimum subdistrict of UE side simultaneously.

In actual applications, there is following problem in such scheme: upgrade optimum subdistrict by existing 1D reporting events method, network side is determined independently, neatly and upgraded optimum subdistrict and cause restriction, and cause the inconsistent of network side and UE side optimum subdistrict easily, cause network side and can't correctly upgrade optimum subdistrict.
Cause the main cause of this situation to be, because in the prior art, only rely on UE by the sub-district is detected, and (when having found new optimum subdistrict) triggers the 1D incident when satisfying the evaluation criteria that presets, the informing network side is upgraded optimum subdistrict, the selection of optimum subdistrict is only determined according to the evaluation criteria that presets by UE that network side can't be determined optimum subdistrict independently, neatly according to the measurement report of UE.
And, in the prior art, UE upgrades UE side optimum subdistrict at once behind the 1D reporting events, network side then needs to wait for the report of reception from the UE side, upgrades optimum subdistrict according to measurement report, because the report of 1D Event triggered is at affirmation mode (Acknowledged Mode, abbreviation " AM ") reports under, the re-transmission situation may take place, cause network side to postpone to upgrade optimum subdistrict, cause the inconsistent of network side and UE side optimum subdistrict; Even and network side received measurement report, also may refuse to accept sub-district that UE reports as optimum subdistrict because local resource is not enough, this type of situation equally can cause network side and UE side optimum subdistrict inconsistent.May influence reporting of follow-up optimum subdistrict and optimum subdistrict is inconsistent, finally influence the selected of optimum subdistrict.For example, sub-district A is the current optimum subdistrict of UE, find that by detecting UE the signal of sub-district B is better than sub-district A, report the 1D incident, and sub-district B is updated to the optimum subdistrict of UE, and network side may be because sub-district B inadequate resource, do not have the optimum subdistrict of acceptance area B as network side, the optimum subdistrict of network side still is sub-district A, under the inconsistent situation of both sides' optimum subdistrict, it is poor that UE has found that again the signal of sub-district C cans be compared to sub-district B than sub-district A, at this moment, because UE side optimum subdistrict is sub-district B, and the signal of sub-district C is poorer than sub-district B, so UE can be for sub-district C report the 1D incident, network side may lose the chance of upgrading optimum subdistrict.
