Specifically, the signal strength for obtaining current service cell, which can be by terminal, to be realized, i.e., in the embodiment of the present invention
The signal strength of terminal acquisition current service cell.Terminal in the present invention can be mobile terminal, and preferably can be has
The mobile intelligent terminal of operating system.
Mobile terminal refers to the equipment that can be used on the move, broad sense say including mobile phone, notebook, tablet computer,
POS machine, or even including vehicle-mounted computer.But refer to mobile phone or the intelligent hand with a variety of application functions in most cases
Machine and tablet computer.As network and technology are towards the development in more and more broadband direction, Mobile Communication Industry will trend
The real mobile message epoch.On the other hand, with the rapid development of integrated circuit technique, the processing capacity of mobile terminal is
Have powerful processing capacity, mobile terminal becomes an integrated information processing platform from simple call tool.This
Also more wide development space is increased to mobile terminal.Mobile terminal is as simple communication equipment with Mobile Communication Development
The history of existing decades.Mobile intelligent terminal is almost changed into the crucial entrance of Internet service between a flash and mainly creates
New platform, new media, e-commerce and information service platform, Internet resources, mobile network resource and environmental interaction resource
Most important hinge, operating system and processor chips even become the strategy system of current entire information and communication technology (ICT) industry
High point.Mobile intelligent terminal can be referred to as intelligent terminal, and mobile intelligent terminal possesses access the Internet capability, usually carry each
Kind operating system can customize various functions according to user demand.In life common intelligent terminal include mobile intelligent terminal,
Vehicle intelligent terminal, smart television, wearable device etc..
Specifically, after terminal selects certain cell as current service cell, the variation of various conditions less in the case where, eventually
End will reside in selected cell, and continue to monitor the information of the current service cell, i.e., terminal obtains current service cell
Signal strength.
Step 102, when the current service cell signal strength meet the first preset condition when, obtain adjacent cell
Reselecting parameters.
