Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] In the embodiment of the present invention, taking advantage of the fact that the user's maximum rate is not equal to the guaranteed rate, several levels of rates are divided between the maximum rate and the guaranteed rate. When non-scheduled resources are allocated for service access, the user can try multiple rates, and the RNC can choose to try access from the maximum rate until it succeeds. During the duration of the service, the RNC dynamically adjusts its occupied resources according to the user's measurement value of the enhanced uplink physical channel E-DCH traffic. When the actual traffic of the user increases, the RNC increases the non-scheduled resources occupied by the user; on the contrary, when the actual traffi...

Abstract

The invention discloses a method for controlling a non-scheduled resource in a high-speed uplink packet access (HSUPA) service. The method comprises the steps of: dividing out one or more levels of rates between the maximum rate and the guaranteed rate, generating a rate list based on the maximum rate, the middle levels of rates and the guaranteed rate; selecting a rate from the rate list as an access rate; allocating non-scheduled resources according to the access rate, if the non-scheduled resources are allocated successfully, finishing; if the non-scheduled resources is failed to allocate, judging whether each rate in the rate list has been tried to be an access rate; if some rates in the rate list have not been tried to be an access rate, continuing to select these rates as an access rate; if each rate in the rate list has been tried to be an access rate, finishing. By the embodiment of the invention, non-scheduled resources are fully used under the condition that a user normally uses the non-scheduled resources, and connection rate is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, relates to a method for controlling non-scheduled resources of high-speed uplink packet (HSUPA) services based on Time Division Synchronous Code Division Multiple Access (TD-SCDMA). Background technique [0002] HSUPA is a technology for uplink performance enhancement launched by 3GPP in the latest R6 stage. It adopts fast scheduling controlled by the base station (Node B), hybrid automatic repeat request (H-ARQ), and shorter transmission time interval ( TTI), high-order modulation and other technologies, the performance has been greatly improved compared with the R4 stage. There are two transmission mechanisms in HSUPA, scheduled transmission and non-scheduled transmission. [0003] A. Scheduling transmission: [0004] When the scheduling method is used for transmission, if the user (UE) has uplink data to be transmitted, it first sends scheduling request i...
