Description
Technical field
The present invention relates to the descending access of high-speed packet (HSDPA) technology, refer to a kind of method that improves handover success rate especially.
Background technology
Soft handover is that Wideband Code Division Multiple Access (WCDMA) inserts the new handoff functionality of (WCDMA) system, is used for the migration of portable terminal (UE) between co-frequency cell, to improve handover success rate.The WCDMA standard is divided into a plurality of different versions such as version (Release) 99, Release 4, Release 5, Release 6 according to the time of releasing, hereinafter to be referred as R99, R4, R5, R6 version.
Wherein, the HSDPA technology appears in the R5 version, the sub-district of compatible R99 version of the cell forward of R5 version and R4 version.Here, will support the sub-district of R99 version to be called the R99 sub-district, support the sub-district of R4 version to be called the R4 sub-district, support the sub-district of HSDPA technology to be called the HSDPA sub-district.Accordingly, the business of supporting in the R99 sub-district is called the R99 business, and the business of the use HSDPA technology that the business of supporting in the R4 sub-district is called the R4 business, support in the HSDPA sub-district is called the HSDPA business.Simultaneously, the R99 business only can be supported in the base station in the R99 sub-district; The R4 business only can be supported in the base station in the R4 sub-district, all can not support the HSDPA business; But in the HSDPA sub-district, R99 business, R4 business can not only be supported in the base station, also can support the HSDPA business simultaneously.All support the soft handover function between HSDPA sub-district and the R99 sub-district and between HSDPA sub-district and the R4 sub-district.In this article, claim R99 sub-district and R4 sub-district to be referred to as conventional cell, R99 business and R4 business are referred to as traditional business.
In the prior art, though can support the soft handover of minizone between HSDPA sub-district and the R99 sub-district, but because when wireless network planning, each sub-district all is difficult to guarantee coverage in full accord of up-downgoing wireless signal, therefore cause owing to the R99 sub-district can't demodulation HSDPA business and reason such as up channel power control, and make the soft handover that can't carry out success between HSDPA sub-district and the R99 sub-district, so the call drop phenomenon in the soft switching process is of common occurrence.Below by two examples the problem that exists in the soft switching process between HSDPA sub-district and the R99 sub-district is elaborated.
Fig. 1 is the R99 business for the UE initial service, and UE from the R99 sub-district along track 11 schematic diagrames that move to the HSDPA sub-district.In Fig. 1, A point expression RNC represents that with Active Set, B point that the HSDPA sub-district adds UE the downlink signal quality of HSDPA sub-district is better than the R99 sub-district, the C point represents that UE has arrived the up coverage of HSDPA sub-district, D point expression RNC deletes the R99 sub-district from the Active Set of UE.RNC reshuffles the process of UE business and is in Fig. 1: when UE by the A point, when further leaving the R99 sub-district near HSDPA sub-district arrival B point, measurement by UE reports, RNC finds that the downlink signal quality of HSDPA sub-district is better than the downlink signal quality of R99 sub-district, therefore is changed to the HSDPA business at the B professional reprovision of UE of naming a person for a particular job.
As can be seen from Figure 1, at the B point, because the UE up coverage of no show HSDPA sub-district also, so the HSDPA sub-district can't receive the upward signal of UE, and can only rely on the R99 sub-district to receive the upward signal of UE; But, because RNC has been the HSDPA business with the business configuration of UE at the B point, though therefore the base station of R99 sub-district can receive that the upward signal of UE also can't demodulate the HSDPA Traffic Channel of UE, thereby the professional upward signal of the HSDPA that causes UE interrupts, and then make the interruption of the whole HSDPA business of UE, produce the call drop phenomenon.
Fig. 2 is the HSDPA business for the UE initial service, and UE from the HSDPA sub-district along track 21 schematic diagrames that move to the R99 sub-district.In Fig. 2, up coverage, C point expression RNC that A point expression UE has arrived the R99 sub-district represent that with Active Set sub-district, B point that the R99 sub-district adds UE the downlink signal quality of R99 sub-district is better than the HSDPA sub-district, D point expression RNC deletes the HSDPA sub-district from the Active Set of UE.RNC reshuffles the process of UE business and is in Fig. 2: when UE by A point and C point, when further leaving the HSDPA sub-district near R99 sub-district arrival B point, measurement by UE reports, RNC finds that the downlink signal quality of R99 sub-district is better than the downlink signal quality of HSDPA sub-district, therefore is changed to the R99 business at the B professional reprovision of UE of naming a person for a particular job.
As can be seen from Figure 2, when UE moved to C point on the track, increased thresholding because the downlink signal quality of R99 sub-district satisfies Active Set this moment, and RNC then adds the R99 sub-district Active Set of UE.As UE during at the C point, because the C point has been positioned within the up coverage of R99 sub-district, the R99 sub-district can obtain UE quality of uplink signal preferably, so the R99 sub-district can will cause the uplink signal strength of UE to reduce by the uplink transmission power of power control reduction UE like this.
Yet because the current use of UE is the HSDPA business, though UE is nearer and have a good up channel condition from the base station of R99 sub-district, the R99 sub-district can't demodulate the HSDPA business that UE uses all the time; Because at the C point, UE is far away from the base station of HSDPA sub-district again, and the R99 sub-district has reduced the uplink signal strength of UE, so the upward signal of UE can not reach the demodulation threshold of HSDPA sub-district, and normal demodulation can not be carried out to UE in the HSDPA sub-district.Can obtain by the above situation analysis that UE is ordered at C: though the professional reprovision of UE is not changed to the R99 business at C point RNC, but because R99 sub-district and HSDPA sub-district all can't demodulate the upward signal of UE, therefore causing UE upward signal will occur at the C point interrupts, and then make the interruption of the whole HSDPA business of UE, produce the call drop phenomenon.
Between HSDPA sub-district and R4 sub-district, there is the problem between above-mentioned HSDPA sub-district and the R99 sub-district equally.
Can obtain based on above analysis Fig. 1 and Fig. 2, though between HSDPA sub-district and conventional cell, can carry out soft handover, but owing to the call drop phenomenon takes place the UE that makes out of season of reconfiguration traffic in soft switching process, therefore seriously influence quality of services for users, reduced handover success rate.
