Embodiment one
The embodiment of the present invention provides a kind of residence reselecting, as it is shown on figure 3, described method may include that
Step 101, the signal intensity of acquisition current service cell.
Concrete, in the embodiment of the present invention, the signal intensity obtaining current service cell can be to be come by terminal
Realize, i.e. terminal obtains the signal intensity of current service cell.Terminal in the present invention can be mobile terminal,
It can be preferably the mobile intelligent terminal with operating system.
Mobile terminal refers to the equipment that can use in movement, and saying of broad sense includes mobile phone, notebook, puts down
Plate computer, POS, even include vehicle-mounted computer.But, refer to mobile phone in most cases or have
The smart mobile phone of multiple application function and panel computer.Along with network and technology are towards the most broadband
The development in direction, Mobile Communication Industry will move towards the real mobile message epoch.On the other hand, along with integrated
Developing rapidly of circuit engineering, the disposal ability of mobile terminal has had powerful disposal ability, mobile
Terminal becomes an integrated information processing platform from simple call instrument.This also increases to mobile terminal
Broader development space.Mobile terminal is existing several with Mobile Communication Development as simple communication equipment
The history of 10 years.Mobile intelligent terminal is almost changed into crucial entrance and the master of Internet service between a flash
Want innovation platform, new media, ecommerce and information service platform, Internet resources, mobile network's money
Source and the most important hinge of environmental interaction resource, its operating system and processor chips even become the most whole
The strategic high ground of information and communication technology (ICT) industry.Mobile intelligent terminal can be referred to as intelligent terminal, mobile
Intelligent terminal has access the Internet capability, generally carries various operating systems, can customize according to user's request
Change various function.Intelligent terminal common in life includes mobile intelligent terminal, vehicle intelligent terminal, intelligence
TV, wearable device etc..
Concrete, after terminal selects certain community to be current service cell, in the feelings that the change of various conditions is little
Under condition, terminal will reside in selected community, and continues to monitor the information of this current service cell, the most eventually
End obtains the signal intensity of current service cell.
Step 102, when the signal intensity of described current service cell meet first pre-conditioned time, obtain neighbour
The reselecting parameters of nearly community.
Concrete, when mobile terminal carries out cell reselection, mobile terminal meeting prioritizing selection signal quality is good
Community, so that the wireless network of mobile terminal is maintained at optimum state, the trigger condition of cell reselection is with letter
Number intensity is main, and the bearing capacity of each community is limited, if the best community of signal quality is stayed
The mobile terminal quantity stayed is too much, and this community is susceptible to congested, then the actual available quality of this community is
Poor.Therefore, when cell reselection, it should the community that selection cell signal quality is best, and community
Signal intensity be not the single factor determining cell quality, affect the factor of cell quality and also includes stably
Property, busy extent etc..
