Problems solved by technology

[0003] Using the above-mentioned existing technologies, the two methods of performing network re-search through NB-IoT have disadvantages. For example, the current cell signal status is already very poor. In this case, still trying to initiate random access has a high probability of failure, which will lead to subsequent The off-network re-search delay is too long; and starting a new cell search directly means that the data sent in the original cell is invalid, because NB-IoT itself has no switching function
[0004] However, in related technologies, there is no effective solution to the above disadvantages

Embodiment Construction

[0038] The implementation of the technical solution will be further described in detail below in conjunction with the accompanying drawings.

[0039] A method for network re-searching in the embodiment of the present invention, such as figure 1 As shown, the method includes:

[0040] Step 101, when the network is in a bad state during the service operation of the NB-IOT terminal, extract the judgment threshold;

[0041] Step 102: Detect whether to initiate network random access in the original cell or to perform network search in the new cell according to the determination threshold.

[0042] In the embodiment of the present invention, when the NB-IOT terminal has a bad state in the network during service operation, it may be a state of link failure. In this state, the extracted judgment threshold may be the link state judgment threshold. Then it can be detected according to the link state determination threshold whether to initiate network random access in the original cell...

Abstract

The invention discloses a network re-searching method, a terminal and a computer storage medium. The method comprises the following steps: when a network is in a bad state in a service operation process for the terminal used for the NB-IOT, a judgment threshold value is extracted; and whether network random access is initiated in an original cell or not is detected according to the judgment threshold value or network searching is carried out in a new cell.

Description

technical field [0001] The invention relates to network search technology, in particular to a network re-search method, terminal and computer storage medium. Background technique [0002] Narrow Band Internet of Things based on cellular (NB-IoT, Narrow Band Internet of Things), as a new generation of Internet of Things, based on mature 4G technology, can organically unify the original fragmented Internet of Things, thus realizing the real "Internet of Everything". ". Currently, when a link failure occurs during an off-network re-search, NB-IoT either directly initiates a random access attempt to restore the link in the original cell, or directly starts the search for a new cell. [0003] Using the above-mentioned existing technologies, the two methods of performing network re-search through NB-IoT have disadvantages. For example, the current cell signal status is already very poor. In this case, still trying to initiate random access has a high probability of failure, which...
