Problems solved by technology

[0016] In the existing scheduling method, because the scheduling is performed every 2ms, the calculation of the cell load and the load currently occupied by each UE is performed every 2ms, so as to be able to calculate the number of cells that can be used for Serving E-DCH Noise rise (RoT, Rise Over Thermal), and then allocate the RoT resources of the cell among Serving UEs according to a specific scheduling algorithm, and then determine to send an appropriate scheduling command. All these operations must be within the specified time Complete, the scheduling algorithm is relatively complex

Embodiment Construction

[0043] The present invention will be described in detail below with reference to the accompanying drawings.

[0044] refer to image 3 , the scheduling method for high-speed uplink packet access according to the present invention includes the following two-level scheduling:

[0045] a first-level scheduling for assigning target noise lift for each user equipment; and

[0046] The second-level scheduling is used to track the allocated target noise rise by sending a relative grant command according to the current grant and channel quality of the user equipment.

[0047] The first-level scheduling may include a non-serving RG DOWN sending decision step and a serving UE target noise rise determination step, wherein the non-serving RG DOWN sending decision step includes determining that the RG needs to be sent when the cell is overloaded and the overload meets the conditions for sending RG DOWN. The non-serving user equipment of DOWN sends the determined information to the second...

Abstract

The invention discloses a dispatching method used for high speed upstream packet access and a system thereof. A first class dispatching, when a district is over-loaded and launching conditions are met, is used for determining UE required to launch non-service RG DOWN and sending information to a second class dispatcher, carrying out priority calculation and sorting to service UE, distributing the upstream load used for E-DCH between the service UE, determining target noise uplift resource to be distributed to each service UE, and sending information to a second class dispatcher. The second class dispatching, when non-service UE needs to launch RG DOWN, launches RG DOWN, estimates signal channel quality after the dispatching authorization comes into effect according to current information of the service UE and historical information, determines the specific authorization required to give to the service UE according to the target noise uplift distributed to the service UE, determines the authorization order demanded to launch, and launches dispatching order to the service UE. The dispatching method of the invention reduces complexity dispatcher and improves implementation efficiency of a dispatcher.

Description

technical field [0001] The present invention relates to service scheduling of wireless communication systems, in particular to a scheduling method and system for high-speed uplink packet access. Background technique [0002] 3G (third generation) wireless mobile communication is in constant evolution and changes, constantly introducing new requirements to achieve low cost and high performance, in the fifth (R5, Release 5) and sixth (R6, Release 6) ) respectively introduced High Speed ​​Downlink Packet Access (HSDPA, High Speed ​​Downlink Access) and High Speed ​​Uplink Packet Access (HSUPA, High Speed ​​Uplink Packet Access), the purpose is to make full use of limited wireless resources to improve the throughput rate and Single User Equipment (UE, User Equipment) peak rate, faster response to UE requests, and reduced delay. [0003] HSUPA is an enhancement technology for the uplink transmission capability of the Wideband Code Division Multiple Access (WCDMA, Wideband Code D...
