Roaming communication method of multi-spectrum radio-television network based on ultra-narrowband internet of things

Abstract

The invention relates to a roaming communication method of a multi-spectrum radio-television network based on the ultra-narrowband internet of things. The method comprises the following steps: intercepting radio information on a control channel designated by a preset control channel parameter after a mobile terminal is turned on, receiving the broadcast information when intercepting the broadcast information, and sending an acknowledgement frame to a corresponding base station; judging whether the mobile terminal is an authentication terminal, when the mobile terminal is the authentication terminal, and sending poll information to the base station in an uplink way through the internet of things by the mobile terminal, reading corresponding data information in the database of a network server by the base station, and sending the read data information to the mobile terminal; receiving downlink data information by the mobile terminal. By use of the roaming communication method disclosed by the invention, the mobile terminal only needs to intercept the radio information on the established control channel, the data communication can be accomplished after the radio information passes the network ID authentication, the calibration on a terminal paging parameter is avoided, a network searching process of the terminal is simplified, and a success rate and a communication efficiency of the mobile terminal are improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a roaming communication method based on an ultra-narrowband Internet of Things multi-spectrum radio and television network. Background technique [0002] With the continuous development of communication technology, not only the connection between people can be realized, but also the connection between things has become more and more common. The current communication technologies used by the Internet of Things are mainly 2G, 3G, and 4G networks of mobile operators. The use of 2G, 3G, and 4G networks requires terminals and base stations to be connected at all times. This method is not suitable for the Internet of Things, because the Internet of Things The terminal does not need to be connected to the Internet all the time, nor does it need to be turned on regularly. The terminal only needs to be connected to the Internet for data transmission when it needs to send data. The ...

The current communication technologies used by the Internet of Things are mainly 2G, 3G, and 4G networks of mobile operators. The use of 2G, 3G, and 4G networks requires terminals and base stations to be connected at all times. This method is not suitable for the Internet of Things, because the Internet of Things The terminal does not need to be connected to the Internet all the time, nor does it need to be turned on regularly. The terminal only needs to be connected to the Internet for data transmission when it needs to send data. The use of 2G, 3G, and 4G networks will not only shorten the service life of the battery in the terminal, but also cause Waste of 2G and 3G network resources, low utilization rate

[0003] The existing roaming communication method requires that the paging parameter is consistent with the paging parameter stored in the terminal to complete the process of finding the network and then complete the communication. However, when the terminal is in the paging parameter saved under the corresponding control signal, it cannot find When the same parameter is consistent with the obtained operator code and country code, it is necessary to switch to the next designated control channel to continue searching for the network. This method is used under network conditions with two or more sets of parameters, such as At the junction, or under test network conditions, the terminal needs to constantly switch parameters to confirm whether the paging parameters are consistent with the corresponding parameters stored in itself, and may even fail to find the network, making the process of finding the network complicated and inefficient, thereby increasing the number of terminals The power consumption of the terminal affects the communication efficiency of the terminal
