Abstract

The embodiment of the invention provides a network link switching method and equipment for a trunking terminal. The method comprises the steps of detecting the network signal quality of a private network in a private network link mode, if it is detected that the network signal quality of the private network meets a first preset condition, starting a public network modem of the trunking terminal, and switching a current link mode from a private network link mode to a public and private network cooperative link mode, and if it is detected that the private network does not transmit the data packet of the current service within a first preset time, closing a private network modem of the trunking terminal, and switching a current link mode from a public and private network collaborative link mode to a public network link mode. According to the embodiment of the invention, service interruption or data loss in a network switching process can be avoided.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a network link switching method and device for cluster terminals. Background technique [0002] Private network refers to a professional network that provides safe and reliable wireless services for the government and public security, public utilities, and industrial and commercial fields. It has the characteristics of independent control and no external restrictions, and is more suitable for specific working environments. streamlined work communication. [0003] Due to the high cost and long construction period of the private network, the coverage area of ​​the private network is limited, and the standard public network is usually used to extend the coverage of the private network. When the private network signal is good, the cluster terminal is in the private network link mode, and in the area where the private network signal is poor or th...
