A method, terminal and server for controlling a domain transfer operation, are discussed. According to an embodiment, the method includes receiving, by a terminal, a domain transfer request message from a network server, the domain transfer request message including domain transfer related information; evaluating, by the terminal, the domain transfer related information and at least one of user preference information and operator policy information; determining, by the terminal, whether to initiate a domain transfer of an ongoing call based on the evaluation result; and selectively initiating, by the terminal, the domain transfer of the ongoing call based on the determination result.

A method, terminal and server for controlling a domain transfer operation, are discussed. According to an embodiment, the server includes a receiver to receive a domain transfer request; a controller to evaluate the domain transfer request based on criteria information, to determine whether or not to generate a domain transfer request message based on the evaluation result, and to generate the domain transfer request message based on the determination result; and a transmitter to transmit the domain transfer request message to at least one terminal so as to selectively initiate a domain transfer for a call.

A terminal, method and system for providing a CS service, a SIP-based service, or a CSI service, are provided. According to an embodiment, the terminal includes a controller to receive a terminal capability version of at least one target terminal, to compare the received terminal capability version with a previously stored terminal capability version of the at least one target terminal, and to determine whether to request for terminal capability information of the at least one target terminal based on the comparison result, wherein the terminal capability version identifies a version of capabilities of the at least one target terminal.
摘要:
Disclosed is a method for selecting and managing a mobility protocol between a network and a terminal in a mobile communication system. When the terminal is to setup an IP tunnel for data transmission/reception with the network supporting a plurality of mobility protocols, firstly, the terminal is configured to transmit a list of terminal-supported mobility protocols and/or its preference information (e.g., information about mobility protocol preferred by the terminal) to the network, and secondly, the network is configured to determine (select) a mobility protocol of an IP tunnel for data transmission/reception with the terminal based on the information, thereby enhancing an efficiency of the resource when the IP tunnel is setup between the terminal and the network.

A method, terminal and server for controlling a domain transfer operation, are discussed. According to an embodiment, the method includes receiving, by a terminal, a domain transfer request from a network server, the domain transfer request including domain transfer related information; evaluating, by the terminal, the domain transfer related information when deciding whether or not to initiate a domain transfer; determining, by the terminal, whether to initiate the domain transfer of an ongoing call based on the evaluation result; and initiating, by the terminal, the domain transfer of the ongoing call when the evaluated domain transfer related information indicates that the domain transfer of the ongoing call needs to be initiated, wherein the domain transfer is for voice call continuity that is capable of transferring voice calls between a circuit switched (CS) domain and an (IMS) domain.
