Method and device for configuring machine class communication terminal capacity

Abstract

The invention discloses a method and a device for configuring machine class communication terminal capacity. The method and the device for configuring machine class communication terminal capacity are used for promoting a (machine to machine) M2M service to progress from a global system for mobile communication (GSM) to a long term evolution (LTE) system. Capacity parameters of machine type communication (MTC) terminal equipment are configured according to a bandwidth and a highest modulation system supported by the MTC terminal equipment, and the capacity of a buffer of the MTC terminal equipment is configured according to a total buffering channel bit number parameter. By limiting the receiving bandwidth and sending bandwidth of the MTC terminal equipment, the largest modulation order and the supported largest hybrid automatic repeat request (HARQ) process number of the MTC terminal equipment are limited, a total buffering channel bit number of the MTC terminal equipment is largely lowered, the buffering requirement of the MTC terminal equipment is lowered, and therefore the cost of the MTC terminal equipment is largely lowered, and the MTC service is promoted to progress from the GSM to the LTE system.

Description

technical field [0001] The invention relates to the field of digital communication, in particular to a terminal capability configuration method and device supporting LTE (Long Term Evolution) low-cost terminals. Background technique [0002] Machine to Machine (M2M for short; also called MTC, Machine Type Communication) communication is a networked application and service centered on intelligent interaction between machine terminals. M2M is the main application form of the Internet of Things at this stage. Achieving machine-to-machine communication means that devices or appliances that are not connected to the Internet in the traditional sense, such as household appliances, security system equipment, factory equipment, medical instruments, etc., have the ability to network and communicate with each other. For example, if the Internet of Things is used for data collection, it can be applied in a variety of scenarios: power equipment operation monitoring, remote meter reading...

AI Technical Summary

Problems solved by technology

In order to avoid the need for mobile operators supporting MTC services to maintain both GSM and LTE systems at the same time, resulting in network maintenance costs, the existing M2M devices based on the GSM system need to evolve to M2M devices based on the LTE system
