Abstract

The present document discloses a method for reducing a number of access times of a multimode terminal. The method includes the following steps: judging a network state of the terminal; acquiring signal intensity of a base station, calculating network delay time according to the signal intensity of the base station, and setting a timer according to the network delay time; and switching a data service when the timer has timed out. The present document further discloses an apparatus for reducing a number of access times of a multimode terminal.

First claim

What is claimed is:

1. A method for reducing a number of access times of a multimode terminal, comprising the following steps:
judging a network state of the terminal;
acquiring signal intensity of a base station, calculating network delay time according to the signal intensity of the base station, and setting a timer according to the network delay time; and
switching a data service when the timer has timed out
wherein the network state comprises a service loss state and a service acquisition state; wherein the process of calculating network delay time comprises:
when the terminal is in the service loss state, the network delay time is a product of signal intensity of a base station of a low-speed network and a delay coefficient and
when the terminal is in the service acquisition state, the network delay time is a product of signal intensity of a base station of a high-speed network and a delay coefficient.

2. The method for reducing a number of access times of a multimode terminal according to claim 1 , wherein the process of switching a data service comprises:
when the terminal is in the service loss state and the timer has timed out, judging whether there is a service of the high-speed network, and when there is no service of the high-speed network, switching the data service to the low-speed network; and
when the terminal is in the service acquisition state and the timer has timed out, judging whether there is a service of the high-speed network, and when there is a service of the high-speed network, switching the data service to the high-speed network.

3. The method for reducing a number of access times of a multimode terminal according to claim 1 , wherein the signal intensity of the base station comprises a power signal and an ecio signal.

4. The method for reducing a number of access times of a multimode terminal according to claim 1 , wherein the delay coefficient is −0.25.

5. The method for reducing a number of access times of a multimode terminal according to claim 1 , wherein judging a network state of the terminal comprises:
sampling the signal intensity rssi of the current high-speed network at a fixed sampling interval T_do_div, and when the sampled rssi is less than a preset minimum threshold R_do_low for the signal intensity of the high-speed network, starting a low value timer T_do_low; and when rssi≥R_do_low, stopping the T_do_low;
recording the delay time T, wherein

when the service is lost, starting a service loss timer T_do_oos instead of reporting the service loss state, and when the service is recovered, stopping the T_do_oos; and
when the time recorded by the T_do_oos reaches the delay time T, reporting the service loss state and judging that the network state of the terminal is the service loss state.
