Connection management method, terminal and network side equipment

Abstract

The invention discloses a connection management method. Via the method, when the state of a terminal is switched, it is not required to send a state switching signaling message to a core network of a base station, and instead, network side equipment determines that the terminal is in an idle state when there is no uplink and downlink data transmission and a first timer is overtime; and the realization complexity of a system is reduced, and time and communication resources are saved. The method comprises that when the terminal is in a power-saving state, the terminal determines whether the first timer exceeds a preset threshold, and if YES, the terminal is switched from the power-saving state to the idle state; the terminal does not sends a state change notification to the network side equipment, and according to change from the power-saving state to the idle state of the terminal, an update TAU message of a tracking position area is sent to the network side equipment; and the terminal receives downlink data from the network side equipment.

Description

technical field [0001] The present invention relates to the communication field, in particular to a connection management method, terminal and network side equipment. Background technique [0002] In the IoT communication system, the delay of downlink services and the reduction of power consumption of terminals are a pair of contradictions. Taking downlink control business as an example, upper-layer applications need to complete the control of equipment, such as switching valves, within a specified time. This usually requires the terminal to wake up periodically to detect whether there is its own downlink service. The shorter the periodic wake-up period, the smaller the delay of the downlink service, and the greater the power consumption of the terminal. Therefore, how to combine the characteristics of each system to achieve a balance between delay and power consumption is a key issue in system design. [0003] In an existing mobile communication system, downlink paging i...

Problems solved by technology

In this case, the complexity of the system implemented by the existing technology is relatively high. The reason is that in order to achieve a consistent understanding of "Paging Occasion", the core network and the terminal need to maintain the consistency of the "Connected" state and the "Idle" state. In this way, based on the timer, it can be estimated whether the terminal is in the PSM power-saving mode; the terminal needs to perform signaling interaction with the core network during the switching process between "Connected" and "Idle", and inform the core network of its own state; not only that , the core network and the base station may also need to be synchronized, so the implementation complexity of the core network and the base station is increased
