Method and device for obtaining network

Abstract

The embodiment of the invention discloses a method for obtaining a network. The method comprises the steps of obtaining the signal strength of a communication network having an association relation with a terminal; judging a relation between the signal strength of the communication network and a first preset threshold; searching a Wi-Fi hotspot signal if the signal strength of the communication network is less than the first preset threshold; and determining an optimal communication network according to a relation between the Wi-Fi hotspot signal and a preset hotspot database by adopting preset rules, and registering to the optimal communication network. Meanwhile, the embodiment of the invention further discloses a device for obtaining a network.

Description

technical field [0001] The invention relates to network acquisition technology in the communication field, in particular to a network acquisition method and device. Background technique [0002] In the network search algorithm of the 3rd Generation Partnership Project (3GPP) standard, ideally, the base station of the telecommunication network transmits the wireless communication signal to the specified cell range, and cannot radiate to other cells to prevent Interference with wireless communication signals of other cells. In practical applications, wireless communication signals are attenuated by the square of the distance. In order to ensure that there must be enough wireless communication signals at the edge of the cell network, the base station will usually increase the transmission power of wireless communication signals to ensure the normal use of telecommunication services at the edge of the cell network. However, this will inevitably cause some wireless communication...
