Machine type communication scheduling method, base station and user equipment

Abstract

Embodiments of the invention disclose a machine type communication scheduling method, a base station and user equipment. One embodiment of the method of in the embodiments comprises the following steps that a base station sends first downlink control information to user equipment in an air interface idle state in a cell, wherein the first downlink control information includes a first resource indication corresponding to a first identification of target user equipment, and the first identification is used to identify the target user equipment in the air interface idle state scheduled by the base station during resource scheduling; and the base station sends a first data packet to the target user equipment according to the first resource indication. On one hand, a problem that the base station can not schedule the user equipment and send a corresponding downlink data packet when the UE is in the air interface idle state is avoided; and on the other hand, a problem that under the condition that a Ready Timer maintained between the base station and a core network device exceeds a time limit, because the user equipment only monitors scheduling based on a fourth identification, downlink data which needs to be sent to the target UE by the core network device can not be sent to the target UE is avoided too.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a machine communication scheduling method, base station and user equipment. Background technique [0002] Machine Communication (MTC, Machine Type Communication) or Cellular Internet of Things (CIoT, Cellular Internet of Things) technology is the integration of wireless communication and information technology, used for two-way communication, suitable for security monitoring, vending machines, goods tracking, meter reading and other fields. According to the object of communication, MTC can be divided into three communication modes: machine-to-machine, machine-to-mobile terminal (such as user remote monitoring) and mobile terminal-to-machine (such as user remote control). MTC communication will be an important application in the future communication field. In the future, MTC communication may mainly cover smart meter reading, medical detection, logistics detection,...

AI Technical Summary

Problems solved by technology

[0004] Compared with traditional services, MTC services have some new features. For example, the transmission time of MTC services is usually very long, which causes the user equipment (English full name User Equipment, referred to as UE) to transmit on the air interface for a long time, which further causes the base station There may be a conflict between the Ready Timer between the core network device and the air interface connection timer between the base station and the terminal, so that the core network device cannot directly send the downlink data packet to the UE: one case is that the Ready Timer has not timed out, and at this time The core network equipment will directly send the downlink data to the base station, but at this time the air interface connection timer on the base station and the terminal has expired, the air interface of the user equipment has been released at this time, the user equipment is in the air interface idle state, the base station cannot schedule the UE, and sends Corresponding downlink data packets; Another situation is that the Ready Timer times out, but the air interface connection timer does not time out, and the Ready Timer times out. At this time, when the core network device has downlink data to be sent to the UE, it will not directly forward the data to the corresponding The base station will instead send a paging request, and the base station will send a paging message. Since the air interface connection timer has not expired, the UE is still in the connected state at this time. It only monitors the scheduling based on its own C-RNTI and cannot send downlink data sent to the UE via the base station
