Abstract

The invention discloses a multi-attribute vertical switching method based on a vehicle-mounted heterogeneous network, and the method comprises the steps: firstly setting a network service value and a network comparison value for a vehicle-mounted terminal; secondly employing the network attribute parameter values of a current service network and a candidate network through employing the TCP / IP protocol data package transmission technology, and generating a multi-attribute decision matrix through standardization processing; thirdly setting weights for all attributes through employing an analytic hierarchy process, and obtaining the performance values of the current service network and the candidate network through employing the multi-attribute distance weighted value calculation; finally judging the priority of the current service network, updating a network comparison value, and achieving the switching of the optimal networks, wherein a first priority network selects a service triggering method, and a second priority network selects a performance triggering method. The method solves problems of package loss and severe time delay of a conventional vehicle-mounted heterogeneous network system in a vertical switching process. The invention provides the method which can enable a vehicle to be able to accurately and quickly select a proper network under the condition of high-speed movement, and carries out the network switching.

Description

technical field [0001] The invention relates to a method in the field of wireless converged network technology, in particular to a multi-attribute vertical handover method based on a vehicle-mounted heterogeneous network. Background technique [0002] Intelligent Transportation Systems (Intelligent Transportation Systems, ITS) is a new type of transportation system with real-time, high efficiency and accuracy. In transportation systems, communication is the basis for performing services. However, the development of the current wireless communication system has prompted the simultaneous existence of multiple access technologies, overlapping and covering each other to form a heterogeneous network. The heterogeneous wireless environment can meet the communication needs of users in the transportation system, so that mobile terminals can connect to the network anytime and anywhere to obtain various services. In a heterogeneous network, the vertical handover technology is the ba...
