Problems solved by technology

[0004] With the advancement of technology, a series of methods to solve this problem have been gradually produced. Since each switching algorithm has strong pertinence, in different environments, the methods adopted have their own advantages and disadvantages, and a single switching algorithm cannot adapt to multiple scenarios. Due to the changing cell environment, it is impossible to further reduce the power consumption of the mobile terminal
Based on the complexity and variability of the environment, using a single algorithm to detect signal strength cannot effectively solve the power consumption problem of mobile terminals

Embodiment 1

[0025] The present invention is based on the existing business switching algorithm of the DVB-H system, and on this basis, proposes a brand-new hybrid DVB-H system switching decision algorithm based on multiple algorithms, such as figure 1 shown, including the following steps:

[0026] 1) The DVB-H mobile terminal enters the cell in turn, and the DVB-H mobile terminal detects whether the environment of the current cell is a road environment according to the received DVB-H signal, and uses the Location Aided Handover Decision-making algorithm to judge whether the current cell environment is a road environment , after the DVB-H mobile terminal accesses a specific cell for the first time, if the current environment is a road environment, then directly use the Location Aided handover algorithm and skip to step 4. At this time, if figure 2 As shown, the DVB-H mobile terminal is in the road environment, the mobile terminal is regarded as a "service", the switching point is regarde...

Abstract

The invention relates to the field of mobile communication, and discloses a mixed type DVB-H system switching decision algorithm. The mixed type DVB-H system switching decision algorithm comprises the steps of (1) adopting a DVB-H mobile terminal to detect whether a current cell is a highway environment or not according to received DVB-H signals, using a LpcationAided switching algorithm if the current environment is the highway environment, skipping to a step (4), (2) adopting the DVB-H mobile terminal to judge whether the current cell is covered by an intelligent repeater, adopting the DVB-H mobile terminal to carry out a stochastic algorithm to select one switching algorithm from a ContextAware switching algorithm, a RepeaterAided switching algorithm, a UMTSAided switching algorithm and a HiddenMarkovModel switching algorithm if the current cell is covered by the intelligent repeater, skipping to the step (4), (3) adopting the DVB-H mobile terminal to carry out the stochastic algorithm to select one switching algorithm from the ContextAware switching algorithm, the UMTSAided switching algorithm and the HiddenMarkovModel switching algorithm, (4) calculating the efficiency of the switching algorithms selected in the step (2) and the step (3), and recording data information. The mixed type DVB-H system switching decision algorithm has the advantages of saving terminal power dissipation and having high application valve.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a hybrid DVB-H system switching decision algorithm. Background technique [0002] At present, DVB-H (Digital Video Broadcasting for Handhelds) mobile terminal is a mobile terminal device that receives multimedia services. During the working process of this device, in order to ensure the quality of service, DVB-H terminals must frequently detect the received signal strength , when the signal strength is lower than a certain threshold, the service will be switched. Under different standards and different systems, the decision-making methods for the mobile terminal to detect the signal strength to switch are different. [0003] The DVB-H system mainly serves digital multimedia broadcasting for mobile terminals. Mobile terminals are generally powered by batteries. In order to increase the battery life, the terminals need to turn off part of the receiving circuits periodically to ...
