Description
Technical field
The present invention relates to the communications field, and more particularly, relate to a kind of method of radio network controller to obtain minimum receiving power.
Background technology
The up flank speed that the R99 standard agreement of WCDMA mobile communication system offers the user is generally 384kbps, and hot zones can provide the speed of 2Mbps.From the supported performance that is used for the dedicated channel (dedicated channel:DCH) of transmitting grouped data of R99, for the user in general area, the function of the transmission Packet Service that the R99 standard agreement provides can satisfy user's demand, but along with Packet Service user's increase and to the demand of high speed packet service, the rate bandwidth that R99 provides can not satisfy hot zones user's demand; Therefore the R5 standard agreement has been introduced a kind of enhancing special uplink channel (Enhanced UL DCH:E-DCH), and this channel has adopted and mixed (HARQ) and Adaptive Modulation and Coding (AMC) technology of retransmitting automatically, makes peak rate can reach 5.76Mbps.Its final purpose is by providing high speed packet service to be inserted the capacity that increases system and reduces transmission delay to improve the requirement of user to service quality (Quality ofService:Qos).And Node B can receive bandwidth power according to the sub-district purpose data rate of the data that are scheduled is controlled.
The received power that the scheduling of Node B control E-DCH is based on maximum received bandwidth total power desired value (Maximum Target Received Total WideBand Power) that radio network controller disposes and current all non-data dispatchings decides in this sub-district all to have the E-DCH received power that the data user can use that is scheduled, and then each user is distributed score value.
But when E-DCH goes up the carrying real time business and has when guaranteeing rate requirement professional, and all have E-DCH and are scheduled the available received power of data division can not guarantee all users' Qos the time in this sub-district, Node B is helpless, because the available resource-constrained of the part that is scheduled.
Based on present existing public-measurement (comprising RSEPS), radio network controller can't be known this congestion situation, so just when the part that is scheduled on the E-DCH can not guarantee Qos, radio network controller can't trigger the load that congested control reduces non-scheduling part, to guarantee the having Qos that guarantees rate business on the E-DCH; Admit control also can't correctly admit refusal, insert again and cause online user's Qos to descend more thereby can accept new user to new user.
In order to remedy the defective that existing public-measurement exists, purpose of the present invention promptly is to provide to increase the E-DCH public-measurement that data division has the minimum received power that guarantees rate requirement that is scheduled, make radio network controller can obtain the E-DCH data division that is scheduled and have the minimum received power that guarantees rate requirement, foundation as Radio Resource is coordinated and guaranteed QoS of customer improves the user's communications quality.
Summary of the invention
Main purpose of the present invention is to provide a kind of radio network controller to obtain minimum receiving power (promptly, the system uplink load) method, by in the public-measurement control messages, increasing the E-DCH measurement request that data division has the minimum received power that guarantees rate requirement that is scheduled, make Node B can report the data division that is scheduled to have the needed minimum received power that guarantees rate requirement, be convenient to radio network controller and carry out allocation of radio resources and coordination, thereby guarantee power system capacity and quality of services for users according to this information.
To achieve these goals, the invention provides a kind of device of radio network controller to obtain minimum receiving power.
The device that obtains minimum received power according to the present invention comprises: the request of measuring of minimum received power issues module, is positioned at the radio network controller side, is used for issuing minimum received power to Node B and measures request; Measure statistical module, be positioned at the Node B side, measure request, the received power that is scheduled data division and have a business that guarantees rate requirement is measured statistics, and calculate minimum received power in response to minimum received power; And public-measurement report sending module, be positioned at the Node B side, send the public-measurement report to radio network controller, wherein, include minimum received power in the public-measurement report.
Wherein, minimum received power is to strengthen the special uplink channel data division that is scheduled to have the minimum received power that guarantees rate requirement.And the request of measuring of minimum received power issues module and issue minimum received power measurement request in the public-measurement control messages.
Wherein, comprise measuring amount, received bandwidth total power report indication, report rule in the public-measurement control messages.And the report rule comprises and reports mode to report rule, event mode report rule and cycle report rule immediately.
In addition, public-measurement report sending module sends the public-measurement report to radio network controller in the report of determining according to the report rule opportunity.When the report rule is reported rule for event mode, to have only when the measurement result of measuring statistical module satisfies the event report rule, public-measurement report sending module ability sends the public-measurement report to radio network controller; When the report rule is reported rule for the cycle, to have only when the measurement report cycle of measuring statistical module arrives, public-measurement report sending module ability sends the public-measurement report to radio network controller.
Wherein, comprise the report amount in the public-measurement report, described report amount has the minimum received power that guarantees rate requirement for strengthening the special uplink channel data division that is scheduled.Comprise received bandwidth total power in the public-measurement report.
