Abstract:
A method configured to set a communication environment of an electronic device is provided. The method includes detecting a user's input and selecting at least two pieces of information from among multiple pieces of user identification information comprised in a single SIM module, and determining communication environments corresponding to the at least two pieces of user identification information. The communication environments are loaded into the electronic device all together.
Abstract:
An apparatus and method for connecting with a network in a portable terminal includes performing measurement on a neighbor cell supporting a first network based on pre-stored neighbor cell information for the first network if neighbor cell information for the first network is not received over a second network when the portable terminal tries to access the first network while camping in the second network.
Abstract:
Disclosed is a communication method that prevents excess message transmission and improves the efficiency of a communication system. The method includes transmitting a first connection request message for a service connection to a network by an electronic device, receiving a first connection reject message for the first connection request from the network, abstaining from retransmission of the connection request to the network based on the first connection reject message, determining whether an operation configured in the electronic device belongs to a condition set by the electronic device based on at least a portion of the abstinence operation, and when determining that the operation belongs to the condition, transmitting a second connection request message to the network.
