Embodiment Construction

[0030] The technical solution of the present invention will be described in detail below in conjunction with the embodiments and the drawings of the specification.

[0031] Such as figure 1 As shown, the LTE uplink radio resource scheduling method of the present invention includes the following steps:

[0032] In step 101, at each scheduling moment, the base station scheduler first traverses all users that have established connections, and classifies users with uplink data transmission requests into different user queues. The user queues are H2H and delay-sensitive M2M user queues. And delay-insensitive M2M user queues; the H2H and delay-sensitive M2M user queues are traditional human-to-human communication users and machine users with high real-time service requirements. The M2M service user queues, All M2M users except machine users with high business real-time requirements;

[0033] In step 102, the base station scheduler first schedules users in the H2H and delay-sensitive M2M u...

Abstract

The invention discloses an uplink resource allocation method in a human-to-human H2H and machine-to-machine M2M terminal coexisting scene and belongs to the technical field of mobile communication. The method comprises the steps of establishing an H2H and time delay sensitive M2M user queue and a time delay non-sensitive M2M user queue, at each scheduling moment; preferentially scheduling users in the H2H and time delay sensitive M2M user queue by a base station scheduler, comparing the maximum transmission rate of each user on each resource block, and preferentially allocating the resource blocks corresponding to the maximums to the corresponding users; and after the scheduling is finished, if the residual resources still exist, scheduling time delay non-sensitive M2M users. According to the method, when mass M2M terminals exist, the service quality of the H2H and time delay sensitive M2M communication service is ensured, moreover, the service feature of the time delay non-sensitive M2M is taken into full consideration, and the transmission performance of an LTE uplink link is improved.

Description

Technical field [0001] The invention belongs to the field of mobile communication technology, relates to a transmission resource allocation method of an LTE system, and can be used in a transmission resource allocation process when an M2M service is introduced into an LTE system. Background technique [0002] M2M is the abbreviation of Machine-to-Machine, which refers to a series of technologies and their combinations that apply communication technology to realize data communication and exchange between people and people, people and machines, and machines and machines. It is a kind of intelligent terminal-oriented Types of information exchange and communication. As the most important application form of the Internet of Things at this stage, M2M is an emerging communication type and a new business growth point in the field of mobile communication. The implementation of machine-type communication in cellular networks is valued and favored by mobile operators. With its wide coverag...
