Abstract: Management of capability information is disclosed. A server in a network acquires information about capability of a user equipment (or terminal) and manages the information in a centralized manner, to reduce signaling through a radio interface between user equipments to thus reduce a waste of radio resources.

Abstract: 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.

Abstract: A method, terminal and server for controlling a domain transfer operation, are discussed.

Abstract: A method and mobile terminal for controlling a voice call continuity (VCC) operation, are provided. According to an embodiment, the invention is directed to a method for controlling a voice call continuity (VCC) operation between a mobile terminal and a network, the method comprising: receiving operator policy via an OMA Device Management (DM) method during at least one call or session established between the mobile terminal and the network, the operator policy including domain transfer restriction information; evaluating the domain transfer restriction information of the operator policy; and selectively initiating a domain transfer according to the evaluated domain transfer restriction information of the operator policy, wherein the domain transfer restriction information indicates that a domain transfer from CS domain to IMS domain is restricted or not or a domain transfer from IMS domain to CS domain is restricted or not.

Abstract: A method for handling CS (Circuit Switching) calls in a VCC (Voice Call Continuity), a VCC application server and an apparatus thereof, wherein first, the VCC application identifies whether a called party number of CS domain calls routed thereto is in an international format, secondly, the VCC application may request to convert the format of the called party number into the international format (referred to as ‘routable number’) if the called party number is not in the international format, thirdly, a translation entity may convert the called party number into the routable number by adding an international prefix suitable for a current location of the originating terminal based on both the called party number and location information on the originating terminal, and then the calls may continue in an IMS domain or a CS domain by the routable number.

Abstract: A method and mobile terminal for controlling a voice call continuity (VCC) operation, are provided. According to an embodiment, the method includes receiving, by a terminal, a message from a network server, the message including domain transfer restriction information; checking, by the terminal, the domain transfer restriction information included in the received message; determining, by the terminal, whether or not to initiate a domain transfer based on at least the domain transfer restriction information; and selectively initiating, by the terminal, the domain transfer based on the determination result.

Abstract: There is provided a multiple network connection method through a first communication device constituting a multiple network together with one or more second communication device, comprises: transmitting a service request message to the second communication device by the first communication device; transmitting a response message including service connection information to the first communication device by the second communication device; transmitting the service request message including the service connection information to a network management server by the first communication device; transmitting a request message to set a new connection path with the second communication device to a service providing entity or an external communication device by the network management server; and generating a new connection path between the service providing entity or the external communication device and the second communication device, and transceiving data through the new connection path.

Abstract: A Session Initiation Protocol (SIP) based session setup method and an terminal thereof, wherein the SIP based session setup method, in a session setup process performed between terminals in a SIP based network which includes at least one or more of the terminals and at least one or more entities, comprises sending a SIP INVITE message from a first terminal to a second terminal, receiving and analyzing the SIP INVITE message by the second terminal, and including a certain service condition in a SIP RESPONSE message, by the second terminal, and sending the SIP RESPONSE message including the service condition to the first terminal.

Abstract: A method and terminal for controlling Voice Call Continuity (VCC) functions initiated by a network, are discussed. According to an embodiment, the method includes receiving, by a terminal, a VCC function notification message, the VCC function notification message including VCC enabling information indicating whether a VCC function of the terminal is to be enabled or disabled; and enabling or disabling the VCC function of the terminal based on the VCC function notification message.

Abstract: A method, server and terminal for providing a Voice Call Continuity (VCC) service, are discussed. According to an embodiment, the terminal includes a storage unit to store operator policy information and user preference information, the user preference information including domain selection information specifying a user-preferred domain to be used when originating the outgoing call from the terminal, the operator policy information including domain selection information specifying a network-preferred domain to be used when originating the outgoing call from the terminal; and a controller to perform a domain selection for the outgoing call based on the user preference information or the operator policy information.
