Problems solved by technology

This method takes into account the characteristics of user data, and adopts a hierarchical division method to alleviate the congestion problem when user data is uploaded at the same time. However, this method still has the disadvantage that a large number of access users in this method will occupy scarce authorized frequency band resources. , resulting in network congestion
This method uses clustering to increase the number of user access, and reduces redundancy through data compression, which effectively solves the congestion problem. However, this method still has the disadvantage that the power consumption of cluster head users in this method is large, and the survival time short

Embodiment 2

[0060] Embodiment 2 of the present invention concrete steps are as follows:

[0061] In the first step, the base station sorts the users.

[0062] The base station sorts all users carrying the same type according to the transmission level, and obtains three user sets, the user set Γ carrying the alarm type 1 , the user set Γ with the type of mobile media 2 , the user set Γ whose carrying type is routine monitoring 3 .

[0063] In the second step, the base station selects an orthogonal mode and allocates a channel for the user.

[0064] User set Γ carrying type alarm 1 All the users are in the orthogonal mode, and the base station allocates idle cellular channels to the users sequentially according to the order of the transmission levels of the users based on the principle of random matching.

[0065] In the third step, the base station selects multiplexing-unlicensed mode and allocates channels for the user.

[0066] The user set Γ carrying type is mobile media 2 All us...

Abstract

The invention discloses an MTC transmission method supporting hybrid licensed-unlicensed frequency bands. The method mainly solves the problem of network congestion caused by a large number of users accessing the authorized frequency band in the prior art, and the problem of large power consumption and short lifetime of cluster head users. The specific steps of the invention are as follows: (1) the base station sorts the users; (2) The base station selects orthogonality for the user Multiplexing mode and allocation channel; (3) The base station selects multiplexing for the user Unauthorized mode and allocated channel; (4) Upload user data. The invention can increase the number of access users, improve the frequency utilization rate, reduce the power consumption of users, and increase the survival time of users.

Description

technical field [0001] The invention belongs to the technical field of communication, and further relates to a machine type communication MTC (Machine Type Communication) transmission method in the technical field of machine type communication that supports mixed authorized-unauthorized frequency bands. The invention can be used for uploading user data in machine type communication. Background technique [0002] Machine-type communication (MTC) is a communication technology based on intelligent machine-type terminals that provides customers with information solutions such as data collection, data measurement, and monitoring and alarming through various communication methods. Driven by technological change and application requirements, infrared transmission Sensing, radio frequency identification, remote control, smart home, location tracking and other application forms have been widely used in people's daily life, which not only brings many conveniences to the lives of ordin...
