Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0019] like figure 1 As shown, this embodiment provides a technical solution suitable for allocation of uplink radio resources in an LTE network, mainly including two aspects of subcarrier allocation and transmission power control. According to the user's authority and the user's real-time transmission requirements, set the appropriate weight for the user's transmission rate, according to the user's location information, use the K-means clustering method to group the users, and use the group as the calculation unit for optimization. On the basis of analyzing the weight and grouping, the wireless resource management is mathematically modeled using the single-objective multi-constraint algorithm. Finally, the mathematical model is changed into a maximum flow problem, and the i...

Abstract

The invention provides a control method for uplink resources in an LTE (Long Term Evolution) network. The method comprises the following steps: determining the weight parameter of the transmission rate of each user according to a preset user permission and a transmission demand; grouping each user according to positions through a clustering algorithm to obtain a plurality of user groups; performing mathematic modeling according to the weight parameter of the transmission rate of each user and the user groups by using a single-target multi-constraint algorithm to obtain a mathematic model; solving the mathematic model by using a preset maximum flow algorithm, and performing uplink resource control on each user. The method provided by the invention is low in calculation complexity, and is more accurate to uplink resource control of the users.

Description

technical field [0001] The invention relates to the technical field of LTE network optimization, in particular to an uplink resource control method in an LTE network. Background technique [0002] In the 4G LTE network, user needs become diverse, and the wireless environment presents complex time-varying characteristics, so efficient wireless resource management is particularly important. LTE network wireless resource management refers to the reasonable allocation and effective management of limited wireless resources in the LTE network, to maximize the utilization of wireless spectrum, to ensure the normal operation of the network, and to meet the requirements of different wireless user terminals in the network. Quality of Service (QoS) requirements. Wireless resources include time, frequency, and transmit power. In uplink data transmission, radio resource management mainly includes two aspects: transmission power control and subcarrier (frequency) allocation. [0003] I...
