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.

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: The present disclosure relates to a method and an apparatus for communication in a portable terminal using multiple Subscriber Identity Module (SIM) cards. The method includes: camping on a predetermined cell by each of the multiple SIM cards; determining whether paging collision occurs between a communication network supported by the predetermined cell on which the portable terminal has camped through a SIM card and another communication network supported by the predetermined cell on which the portable terminal has camped through another SIM card; identifying paging information through a predetermined SIM card among the multiple SIM cards after identifying camp-on information for each SIM card when a result of the determination shows that the paging collision occurs; and performing a paging standby for the communication network in the predetermined camped-on cell by the SIM card corresponding to the identified paging information based on a result of identifying the paging information.

Abstract: Disclosed is a device and a method for processing an emergency call in a portable terminal regardless of a SIM card activated by a user's selection. The device includes a plurality of SIM cards, and a controller to make a control so that a SIM card capable of performing a communication service is automatically switched and the emergency call is transmitted when an emergency call transmission is generated.

Abstract: A call control system and method for mobile video telephony that enables an automatic call setup between a mobile video telephony terminal and a mobile audio-dedicated terminal is disclosed. A call control method for communication between mobile terminals having different capabilities includes receiving, at a called party terminal, a call setup message, transmitting a disconnection message to a calling party terminal in response to the video call setup message and performing a call setup procedure triggered by the called part terminal.

Abstract: A device and method for managing information data in a mobile IP-based mobile telephone. The device and method employ an embedded web server for displaying a homepage of the mobile telephone on a web browser when linked to the mobile telephone through the web browser; and a program of server driven by the embedded web server to generate a command to enable communication between the mobile telephone and a telecommunication system using the web browser and to transmit a message confirming that data updated in the web browser has been updated in the mobile telephone to the web browser. The homepage of the mobile telephone is adapted to display information management menus of the mobile telephone and includes a language pack that stores at least one language so that the information management menus can be displayed in any selected language. The system and method further employ a memory for storing data of the information management menus.

Abstract: A network search method of a user equipment (UE) for a wireless communication system that improves network search speed for acquiring Public Land Mobile Network (PLMN) available list available where the user equipment is located. A network search method measures powers of all the frequency bands supported by a UE in response to a network search request, generates a scan list as a result of measurement of the powers, searches networks listed in the scan list for available channels; acquires neighbor cell information from a system information message of one of the available channels. In addition, the method skips the networks indicated by the neighbor cell information in search of networks by removing the networks from the scan list.

Abstract: An emergency message service method and apparatus for a mobile terminal in which the emergency message service can be effectively utilized even when call forwarding is active in the mobile terminal. The detection and deactivation of call forwarding for an emergency message permits an emergency call to be rapidly established. The emergency message service method may include: checking, upon detection of an emergency message request, the setting status of call forwarding; deactivating, when call forwarding is active, call forwarding; sending, after deactivation of call forwarding, a requested emergency message using a pre-enrolled subscriber number.

Abstract: An error correction system and method for a mobile terminal is provided that are capable of correcting transmission packet errors. The error correction method for a mobile communication system including at least one mobile terminal receiving ciphered text from a network includes generating an output by applying an input parameter containing an overflow counter calculated by the mobile terminal to a predetermined algorithm; deciphering the ciphered text using the output to recover a clear text; updating the overflow counter if the ciphered text is not successfully deciphered; regenerating the output using the updated overflow counter; and recovering the clear text using the regenerated output with the ciphered text.
