Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] like figure 1 The illustrated embodiment is that the embodiment is a LTE scheduling method based on traffic measurement, including N users {u 1 , u 2 ,...,u N}, set u i is each user, u i ∈{u 1 , u 2 ,...,u N};

[0035] Step 1: Latency evaluation;

[0036] (1-1) Set multiple service types {j=1, 2, ... M}, for each user u i The waiting time for applying for business j is TW ij , the maximum delay is TM ij , to calculate its delay weight Among them, e (·) Represents an exponential function with base e;

[0037] (1-2) Calculate each user u i The multi-service comprehensive delay weight of

[0038] Step 2: business measurement;

[0039] (2-1) Set each user u i The arrival probability of application service j at time t is ρ ar_ij t , the blocking rate is α ij t , the application probability is ρ ap_ij t , calculate...

Abstract

The invention discloses an LTE scheduling method based on business measurement. In the method, N users {u1, u2, ..., uN} are included, ui is set to be the i-th user, and ui belongs to {u1, u2, ..., uN}. The method comprises the following steps of (1-1) delay estimation; (1-2) business measurement; (1-3) bandwidth accounting; and (1-4) user scheduling. The method provided by the invention has the characteristics as follows: balance between delay sensitivity of real-time business and fairness of the system is achieved, application of the user business can be dynamically tracked, occupancy of system resources is estimated, and thus reasonable distribution of resources is ensured, and service quality of business development is facilitated to ensure customer perception.

Description

technical field [0001] The invention relates to a dispatching method of an LTE system, in particular to a fairness dispatching method based on service measurement. Background technique [0002] The vigorous development of the mobile Internet makes LTE, as a wireless broadband communication technology capable of guaranteeing multi-service Quality of Service (QoS) and user fairness, more and more widely used. To improve system resource utilization, LTE adopts a shared channel mechanism to dynamically allocate physical resources between users in a timely manner according to factors such as rapidly changing propagation environment, external interference, and system load. Therefore, the scheduling mechanism is very important in the LTE system. Scheduling services include non-real-time services and real-time services. Non-real-time services are not highly sensitive to scheduling. Real-time services have higher requirements on packet loss rate, system throughput and service delay,...
