Multi-service type self-adaptive switching judgment method combined with RSS (Received Signal Strength) prediction

Abstract

The invention discloses a multi-service type adaptive switching judgment method combined with RSS (Received Signal Strength) prediction. The multi-service type adaptive switching judgment method comprises the following steps of: 1, initializing a screening threshold; step 2, scanning surrounding networks; step 2.1, constructing a candidate network; 3, the MD obtains candidate network state information; step 4, the MD detects the service type; step 5, the service type weight information Wb is initialized; 6, the MD detects user preference information; 7, the collected information is uploaded; 8, weight information is updated, and data normalization processing is carried out; step 9, calculating and determining an optimal target network; step 10, executing switching; 11, storing the information; step 12, performing prediction; step 13, calculating a screening threshold RSSth in a screening mechanism; step 14, updating a screening threshold value; and step 15, repeating iteration until the end. According to the method, the MD can adaptively realize the selection and switching of the target network in the UD-HWN, and the signaling interaction between the MD and the BS can be reduced by predicting the RSS between the MD and the optimal target BS at the future moment, so that the energy consumption of the MD is reduced, the available bandwidth of the network is increased, the calculation amount of target network selection is reduced, the switching efficiency is improved, and adaptive switching is realized.
