Lead code distribution method of Internet of Things based on business blocking rate differentiation guarantee

Abstract

The invention discloses a lead code distribution method of the Internet of Things based on business blocking rate differentiation guarantee, which is mainly used for solving the problem that the traditional lead code distribution method easily results in blockage when being used for realizing the random access of lead codes in M2M and H2H business games. The lead code distribution method comprises the following steps of: classifying and respectively carrying out statistics on newly accessed and arrived businesses by using an evolved base station eNodeB to acquire a business statistic when a business statistics period is ended; calculating a business weighted average arrival rate, and carrying out differentiation lead code distribution on the two businesses by utilizing an H2H business blocking rate guarantee algorithm; broadcasting the number of the distributed lead codes to a terminal by using the evolved base station eNodeB, and then finishing the lead code period of the current period. By using the lead code distribution method, the high-priority H2H business can be kept to be prior distributed to a lead code resource to reduce the blockage of the H2H business, and meanwhile, the access of the M2M business is allowed to the maximum extent; and the lead code distribution method can be used for the lead code distribution of the Internet of Things in an LTE(Long Term Evolution) system.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and relates to a random access resource allocation method of an LTE system, in particular to an Internet of Things preamble allocation method based on a service blocking rate differentiation guarantee, which can be used for random access when introducing M2M services into an LTE system. Into the preamble allocation process. Background technique [0002] Machine-type communication (M2M), as the most important application form of the Internet of Things at the present stage, is an emerging communication type. As a new business growth point in the field of mobile communication, the implementation of machine-type communication in cellular networks has attracted the attention and attention of mobile operators. Moreover, the cellular network has the characteristics of wide coverage, low construction cost, and convenient deployment, which also provide favorable conditions for implementing ma...

Problems solved by technology

[0008] This preamble allocation method with the total throughput as the optimization goal, although the total throughput of the system is guaranteed, may lead to the result that many low-priority M2M services are allowed to access the system, while high-priority H2H services are not. Seriously blocked, so the high priority and low blocking rate characteristics of H2H services cannot be guaranteed, and it does not meet the ultimate goal of network optimization
