Network access method and system in mobile terminal group moving process

Abstract

The invention discloses a network access method and system in a mobile terminal group moving process. The method includes the following steps that: the movement direction modes of mobile terminals in a mobile terminal group are obtained, and a dynamic weighting load evaluation model is established, and candidate access networks are selected according to evaluation results calculated by the evaluation model; the candidate access networks obtain evaluation indexes, and a normalized evaluation model is established according to the evaluation indexes; and an access network selection decision-making model of the mobile terminal group is established according to the normalized evaluation model, and the access network selection decision-making model is solved, and a solved result is an optimal access network, and the mobile terminal group performs network access through the optimal access network. With the network access method and system in the mobile terminal group moving process of the invention adopted, the mobile terminals in the mobile terminal group can access the optimal network, and the switching outage rate of the mobile terminals in the mobile terminal group can be decreased, and network throughput can be ensured.

Description

technical field [0001] The present invention relates to the field of network communication, in particular to a network access method and system during group movement of mobile terminals. Background technique [0002] In the actual mobile scenario, the heterogeneous network environment has multiple wireless network access technologies. How to select the most suitable network access for heterogeneous mobile terminals with multiple wireless interfaces in the heterogeneous network environment is to achieve seamless mobility and improve The key to mobile end-user service experience. [0003] At present, the representative ones in the existing technology are: the access network selection technology based on the cost function, which uses the cost function to measure the priority characteristics of the access network, but this method only considers part of the decision parameters, with the increase of the decision parameters , the design of the cost function cannot reasonably refle...

[0003] At present, the representative ones in the existing technology are: the access network selection technology based on the cost function, which uses the cost function to measure the priority characteristics of the access network, but this method only considers part of the decision parameters, with the increase of the decision parameters , the design of the cost function cannot reasonably reflect the performance of the access network; the access network selection technology based on the utility function obtains an optimized resource allocation scheme by maximizing the utility of each access network, but the defect is that the selected utility The function does not combine user preferences with the actual situation of the network, which affects the accuracy of the judgment

The network access in the prior art enables the mobile terminal to access the best network, and the switching interruption rate of the mobile terminal is relatively high
