Abstract
A method and an apparatus for attempting to access a network from among a plurality of networks by a mobile terminal is provided. The method includes attempting to access the network through at least one target channel determined by the mobile terminal, such that the at least one target channel has a measured signal quality value at least equal to a predetermined reference value among signal quality values measured for channels corresponding to network access provider identification information indicating a network having a highest priority among the plurality of networks.
Claims8
A method for attempting to access a network from among a plurality of networks by a mobile terminal, the method comprising:
- attempting to access the network through at least one target channel determined by the mobile terminal, such that the at least one target channel has a measured signal quality value at least equal to a predetermined reference value among signal quality values measured for channels corresponding to network access provider identification information indicating the network having a highest priority among the plurality of networks, wherein attempting to access the network comprises:
- sequentially selecting the signal quality values measured for the channels corresponding to the network access provider identification information indicating the network having the a highest priority among the plurality of networks, one-by-one, according to a descending order from a highest signal quality value;
- and
- attempting, when a selected signal quality value is at least equal to the a predetermined reference value, to access the network through a target channel having the selected signal quality value;
- updating a prior reference value based on a signal quality of the target channel having the selected signal quality value when the mobile terminal does not receive a response to an attempt to access the network through the target channel;
- and
- initializing, when the mobile terminal has moved a predetermined distance after the prior reference value is updated, the updated reference value.
An apparatus for attempting to access a network from among a plurality of networks by a mobile terminal, the apparatus comprising:
- a transceiver for transmitting or receiving a signal;
- and
- a controller for controlling the transceiver to attempt to access the network through at least one target channel determined by the mobile terminal, such that the at least one target channel has a measured signal quality value at least equal to a predetermined reference value among signal quality values measured for channels corresponding to network access provider identification information indicating the network having a highest priority among the plurality of networks, wherein the controller updates a prior reference value based on a signal quality of the target channel having the selected signal quality value when the mobile terminal does not receive a response to an attempt to access the network through the target channel,
- wherein the controller sequentially selects the signal quality values measured for the channels corresponding to the network access provider identification information indicating the network having a highest priority among the plurality of networks, one-by-one, according to a descending order from a highest signal quality value, and when a the selected signal quality value is at least equal to a predetermined reference value, attempt to access the network through a target channel having the selected signal quality value, and
- wherein when the mobile terminal has moved a predetermined distance after the prior reference value is updated, the controller initializes the updated reference value.
