Method and apparatus for detecting connection loss of terminal

Abstract

The invention discloses a method for detecting a connection loss of a terminal, and the parameters for detecting the connection loss are added to the subscription data of the terminal. The method comprises that a network-side device obtains the subscription data of the terminal after receiving an attach request from the terminal, performs a connection loss detection for the terminal and reports a connection loss when the connection loss of the terminal is detected. The invention also discloses a connection loss detection apparatus for realizing the above method. According to the invention, the detection of whether the connection of the terminal is lost is realized by configuring a loss detection timer and the terminal status is monitored at a cost of a relatively small change of the protocol. Therefore, the drawbacks in the management of the terminal in the prior art are eliminated, and the monitoring management of the terminal is greatly facilitated.

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
