Problems solved by technology

[0004] In the future, the number of M2M communication terminals will be at least two orders of magnitude more than the number of H2H communication terminals. M2M terminals will access the network through the uplink of the 3GPP LTE access network (E-UTRAN), and connect to the network through the LTE core network. The central server of the M2M terminal or other M2M terminals communicate. There are many types of M2M services. Most of the service characteristics are completely different from traditional voice services and data services. The existing LTE uplink scheduling algorithms do not consider the existence of a large number of M2M terminals. If the existing LTE uplink scheduling algorithm is still used, it will seriously affect the transmission performance of the uplink and the QoS guarantee of H2H communication.

Embodiment 1

[0035] like figure 1 As shown, the LTE uplink radio resource scheduling method of the present invention generally includes the following steps:

[0036] Step 101, at each scheduling moment, the base station scheduler traverses all users with established connections, and classifies users with uplink data transmission requests into different user queues.

[0037] The user queue is an H2H user queue and an M2M user queue. The H2H user queue not only includes H2H users waiting to send data, but also includes M2M users who have high real-time data to be sent. In particular, such as real-time video surveillance services, M2M The user queue includes M2M users waiting to send data.

[0038] Step 102, the base station scheduler preferentially schedules the users in the H2H user queue, so as to ensure the priority and service quality of H2H user services.

[0039] Step 103: After the scheduling of the H2H user queue is completed, the users in the M2M user queue are scheduled when ther...

Abstract

The invention relates to a wireless resource scheduling method of an LTE (Long Term Evolution) uplink, belonging to the technical field of mobile communication. The method comprises the following steps of: 101 step, establishing a human-to-human (H2H) user queue and a machine-to-machine (M2M) user queue at each scheduling time; 102 step, scheduling users in the H2H user queue by a base station scheduler preferentially; and 103 step, if residual resource blocks (RBs) exist after the scheduling the users in the H2H user queue is finished, scheduling the users in the M2M user queue. The method provided by the invention aims to ensure the quality of service (Qos) of H2H communication businesses and the fairness of the users preferentially while a great amount of the M2M communication users exist in the future; meanwhile, by fully considering M2M business characteristics, two-dimensional resources such as time and frequency are used to greatest extent for providing services for the M2M users, therefore, the transmission property of the LTE uplink is improved.

Description

1. Technical field [0001] The present invention relates to the technical field of mobile communication, in particular, the present invention relates to a 3GPP Long Term Evolution (Long Term Evolution, LTE) uplink radio resource scheduling method. 2. Background technology [0002] M2M is the abbreviation of Machine-to-Machine, which is a type of information exchange and communication for intelligent terminals. In a broad sense, M2M includes Machine-to-Machine, Man-to-Machine, Machine-to-Man, Mobile-to-Machine ) between information exchange and communication, which covers all the technologies and means of information exchange between people, machines and systems that can be realized, that is, the Internet of Things in a broad sense, and will be widely used in all walks of life in the future and people's daily life. According to an estimate by authoritative organizations, the number of M2M communication terminals in the future will far exceed the number of terminals for human...
