Example Embodiment

[0015] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0016] The method of the present invention based on the ant colony algorithm multi-mode terminal to select the target network that guarantees the quality of service is that the base station first obtains the quality of service (QoS) of each multi-mode terminal in each target network that can be selected by the multi-mode terminal. Service) value, and then call the ant colony algorithm, that is, imitate the method of finding the forward path during the foraging process of ants, and select the optimized target network for each multi-mode terminal; the ant colony algorithm first uses natural numbers to separately determine the forward path of the ants The number of steps and the paths available for selection are sorted and numbered, and the total numbe...

Abstract

A method for a multi-mode terminal to select target networks with guaranteed quality of service on the basis of ant colony optimization is used for selecting optimized target networks for each multi-mode terminal by specifics that a base station acquires value of quality of service of each multi-mode terminal in each target network according to feedback of the multi-mode terminal and then simulates the ant colony optimization for searching advancing paths during foraging of ants, and includes steps of firstly, sequencing and numbering steps of ant advancing paths and selectable paths with natural numbers respectively and setting the total number of iterative algorithm; secondly, simulating the multi-mode terminals to select the target networks according to value of quality of service of different networks by the method selecting paths on the basis of different pheromone concentration and visibility in the ant advancing paths; calculating fitness of each path in the iterative algorithm after each section of advancing paths, updating the pheromone concentration of the paths according to the fitness, judging whether reaching the set times of the iterative algorithm or not so as to stop the ant colony iterative algorithm to output the optimal target networks selected by different multi-mode terminals.

Description

technical field [0001] The present invention relates to a method for selecting a target network by a multi-mode terminal based on an ant colony algorithm. Specifically, it relates to a method for a multi-mode terminal to select a target network that can guarantee service quality based on an ant colony algorithm, and belongs to the technical field of wireless communication . Background technique [0002] From the end of the 20th century to the 21st century, GSM, CDMA, WCDMA, TD-SCDMA, CDMA2000, LTE, IMT-advanced, WiMAX, 802.11a / b / g / n, UWB, Bluetooth, Zigbee and RFID etc. Various access transmission technologies are constantly emerging, and the multi-mode network is showing a more diverse and complex trend. Existing wireless access technologies and new wireless access technologies coexist and complement each other at the same time, forming an overlapping and covering multi-mode wireless network. The multi-mode network environment requires the support of multi-mode terminals....
