Problems solved by technology

However, within this 250ms, the buffer state of the UE may change greatly
The BSR information obtained by the eNB side is seriously outdated, and the scheduling result based on it does not match the amount of data that the UE currently needs to send, thus reducing the resource utilization and throughput of the system
[0012] 2. The existing packet scheduling algorithm of LTE usually makes a compromise between user fairness and system throughput, without considering the different services included in each user and the different service quality requirements between services, so that it cannot meet different service qualities Quality of service requirements such as delay and throughput of services of grade and service flow

Embodiment Construction

[0050] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0051] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, a kind of uplink resource scheduling method for 3G / 4G satellite mobile communication network of the present invention, its steps are:

[0052] S1: Cache amount prediction;

[0053] User equipment UE (User Equipment) pairs T in each scheduling period n Predict the cached amount of service data after a certain period of time, and report the predicted value of the buffered amount to the evolved Node B (evolved Node B) through the BSR (Buffer Status Report) in units of Logical Channel Group LCG (Logical Channel Group); among them, T n is the time from when the user equipment UE sends a scheduling request and BSR to the evolved base station eNB to when the UE receives the corresponding resource scheduling result;

[0054] S2: Calculate the priority of the user eq...

Abstract

The invention discloses an upstream resource dispatching method and an upstream resource dispatching device directed at a 3G (the 3rd generation telecommunication) / 4G (the fourth generation telecommunication) satellite mobile communication network. The upstream resource dispatching method directed at the 3G / 4G satellite mobile communication network includes steps: S1, forecasting caching amounts: using UE (user equipment) to forecast each caching amount of business data after Tn time in each dispatching cycle, and reporting predicted values of the caching amounts to an evolution base station eNB through a BSR (bottom simulating reflector) by setting a LGG (logic channel group) as a unit of the predicted values; S2: calculating the priority level of the UE: enabling an upstream resource dispatcher of the evolution base station eNB to receive a dispatching request sent by the UE i, and calculating the priority level of the UE i; S3, allocating upstream resources: using the upstream resource dispatcher of the evolution base station eNB to sequentially allocate the upstream resources for multiple sets of the UE according to the priority level of the multiple sets of the UE. The upstream resource dispatching device directed at the 3G / 4G satellite mobile communication network is used to implement the upstream resource dispatching method directed at the 3G / 4G satellite mobile communication network. The upstream resource dispatching method and the upstream resource dispatching device directed at the 3G / 4G satellite mobile communication network can improve resource utilization rate and handling capacity of a system, and can meet service quality of time delay, handling capacity and the like of different types of business well.

Description

technical field [0001] The present invention mainly relates to the field of mobile communication, in particular to an uplink resource scheduling method and device for 3G / 4G satellite mobile communication network. Background technique [0002] The LTE satellite mobile communication system introduces the 3rd Generation Partnership Project 3GPP (The 3rd Generation Partnership Project) Long Term Evolution LTE (Long Term Evolution) standard into satellite communication, and constructs a ground-like LTE network system in space. The system combines the characteristics of high data rate of LTE and wide coverage of satellite communication, and has unique advantages in realizing high-speed global coverage of mobile communication. [0003] 3GPP started the LTE project in 2005. Compared with the third-generation mobile communication system, LTE has the characteristics of high speed, low round-trip delay, high efficiency and variable bandwidth. In uplink scheduling transmission, LTE ad...
