Problems solved by technology

[0027] According to the above description, UE requests information for Node B scheduling mainly through two methods, one is Happy Bit, and the other is SI information; since UE generates an important parameter of Happy Bit: Happy Bit Delay Condition, it is not transmitted Therefore, even if the Node B knows the SI information of the UE, it cannot determine the UE’s demand for scheduling authorization, which leads to unreasonable SGs allocated to the UE during scheduling, and may cause the SGs allocated to the UE to be too large, resulting in waste of resources. It may be too small, causing the UE to be dissatisfied with the SG. It can be adjusted through the following Happy Bit, but the response time to the UE request is lengthened, and eventually the scheduling performance of the Node B scheduler is affected to a certain extent. At the same time, resources will appear to a certain extent. waste, the service delay of the UE will also increase to a certain extent

Embodiment Construction

[0057] In order to facilitate a deep understanding of the technical content of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0058] The present invention instructs the UE to fill in the Happy BitDelay Condition information element (IE, Information Element) by introducing a new Happy BitDelay Condition information element (IE, Information Element) into the Enhanced Dedicated Physical Channel Information (E-DCH Infomation) of the Node B Application Part (NBAP: Node B Aplication Part) protocol. The Happy Bit Delay Condition information used in the Bit field provides a reference for the HSUPA scheduler of the Node B to calculate the UE's SG request and allocate the UE's SG. The HSUPA scheduler of the Node B can accurately calculate the UE's scheduling request through the above Happy Bit Delay Condition parameter and the SI information reported by the UE, and then reasonably al...

Abstract

Characters of the method are that when receiving authorizing request of dispatch from UE, HSUPA despatcher of Node B assigns dispatching authorities based on Happy Bit Delay Condition information in Node B. the information of Happy Bit Delay Condition is contained in enhanced dedicated physical channel in protocol of Node B application part. The invention also discloses method for enhancing dispatching performance of HSUPA. Estimating authorizing request of dispatch of UE, the method raises dispatching performance of despatcher of Node B.

Description

technical field [0001] The invention relates to the field of communication, in particular to the scheduling of High Speed ​​Uplink Packet Access (HSUPA, High Speed ​​Uplink Packet Access) services in a Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access) wireless communication system. Background technique [0002] The third generation (3G) wireless mobile communication is in constant evolution and change, constantly introducing new requirements to achieve low cost and high performance, in the fifth version (R5, Release 5) and sixth version (R6, Release6) High Speed ​​Downlink Access (HSDPA, High Speed ​​Downlink Access) and HSUPA are respectively introduced in the system, the purpose of which is mainly to improve the utilization rate of wireless spectrum and improve the overall performance of the system. [0003] HSUPA is an enhancement technology for uplink transmission capability of WCDMA system. It mainly introduces three technologies: ph...
