Method and device for detecting terminal connection loss

Abstract

The invention discloses a method for detecting connection loss of a terminal, which adds detection parameters of connection loss in the subscription data of the terminal; the method includes: after receiving the attachment request of the terminal, the network side equipment acquires the subscription data of the terminal, and performing connection loss detection on the terminal, and reporting when the connection loss of the terminal is detected. The invention also discloses a device for detecting terminal connection loss which realizes the above method. The present invention realizes the monitoring of whether the terminal connection is lost by setting the loss detection timer, realizes the monitoring of the terminal state with a small protocol modification cost, makes up for the lack of terminal management in the prior art, and greatly facilitates Monitoring and management of terminals.

Description

technical field [0001] The present invention relates to a connection loss detection technology of Machine Type Communication (MTC, Machine Type Communication) equipment, in particular to a method and device for detecting terminal connection loss. Background technique [0002] figure 1 It is a schematic diagram of the structure of the cellular wireless communication system, such as figure 1 As shown, the cellular wireless communication system is mainly composed of a core network (CN, Core Network), an access network (RAN, Radio Access Network) and terminals. The core network is responsible for non-access layer affairs such as terminal location update, etc. The core network is also the anchor point of the user plane. The access network includes base stations, or base stations and base station controllers. The access network is responsible for access layer affairs such as management of wireless resources, etc. There may be physical or logical connections between base stations...

Problems solved by technology

[0006] However, the business of MTC equipment is different from that of ordinary terminals. For example, the data reporting cycle of logistics monitoring equipment is relatively long, while the data reporting time of digital medical monitoring equipment is relatively short. For different business applications, MTC users may need different detection cycles to obtain The state of the MTC device, the unified terminal reachable timer and the implicit detach timer are not enough to meet the needs of different MTC users
