The invention discloses a link selecting method and a device, wherein a link condition that a terminal has is analyzed according to the terminal characteristics and geographic locations of the terminal; the service type is analyzed; and the quantity of the service data is analyzed; a satellite navigation link is used preferentially for the geographic location; if the condition is not met, a ground communication link is selected preferentially; if the ground communication link condition is not met, a satellite communication link is selected; the ground communication link is selected preferentially for the non-location information; if the ground communication link condition is not met and the data quantity is small, the satellite navigation link is used; if the conditions are all not met, the satellite communication link is used. With the adoption of the link selecting method and the device, different links can be selected according to different requirement conditions and system scales; the system resource is utilized effectively; the system capacity is improved; and the user service quality (QoS) can be met.
Description
technical field [0001] The invention relates to a link selection method and device based on the fusion of multiple networks. Background technique [0002] Today, the integration of different networks, the integration of wireless networks and fixed networks, and the integration of terrestrial networks and satellite networks has become a future development trend and has attracted more and more attention. With the continuous maturity of multi-network integration technology and market, multi-network integration solutions cover various fields such as personal communication, enterprise private network, military battlefield communication support, and emergency communication. The following takes logistics as an example to introduce the importance of link selection in multi-network convergence. [0003] The existing logistics and transportation information platform based on satellite navigation technology mainly provides services such as positioning monitoring, alarming, and standar...
