The present invention relates to an efficient method and apparatus for remotely providing/downloading a profile for use in a communication service in a communication system, and the method for downloading the profile in the communication system, according to one embodiment of the present invention, comprises the steps of: transmitting, to a first server, first information for processing a request for downloading a profile; receiving, from the first server, address information of a second server processing the request for downloading the profile on the basis of the first information; transmitting, to the second server, second information for calling a function, of an application, related to the downloading of the profile; receiving, from the second server, the profile-related information as a response of the second information for calling the function; and connecting to a third server providing the profile on the basis of the profile-related information, and downloading the profile.

Method and apparatus for remotely providing profile in communication system

Disclosed are: a communication technique and a system therefor for fusing, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system. Provided is a method for installing a profile of a terminal having an embed universal integrated circuit card (eUICC) in a mobile communication system, the method comprising: requesting for an eUICC authentication certificate to an eUICC and receiving the eUICC authentication certificate; and transferring a profile package to the eUICC so as to install a profile, wherein the received eUICC authentication certificate further comprises an eUICC manufacturer (EUM) authentication certificate.

Technique for managing profile in communication system

The present disclosure relates to a communication technique for combining a 5G communication system for supporting a higher data transmission rate than a 4G system with an IoT technology, and a system therefor. The present disclosure can be applied to 5G communication and IoT related technology-based intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail business, security and safety related services, etc.). The present invention performs cross-certification of a universal integrated circuit card (UICC) with a subscription manager data preparation+ (SM-DP+) system in a wireless communication system, and receives a profile from the SM-DP+ system according to the cross-certification result, wherein the profile comprises one of a profile encrypted on the basis of a key set established according to the cross-certification result, and a profile transmitted through a session established according to the cross-certification result.

Method and apparatus for downloading profile in wireless communication system

Disclosed is a 5G or pre-5G communication system to be provided for supporting a data transmission rate higher than that of a 4G communication system such as LTE. Provided is a multilink-based data transmission method by which a data transmission device connected to a plurality of links transmits data, comprising the steps of: generating link state information including information on environments of the plurality of links; receiving link configuration information including information on available links; generating a weight for the plurality of links on the basis of the link state information and the link configuration information; selecting at least one link from among the plurality of links for which the weight is generated; and transmitting data to the selected at least one link.

Method and device for transmitting data over a selected link in multilink environment

The present invention relates to a method and device for efficiently transmitting and receiving a profile for providing a communication service in a mobile communication system. A method for supporting remote reception of a profile in a wireless communication system according to an embodiment of the present invention comprises the steps of: receiving a second message including a first message for downloading the profile from a server managing the profile; and transferring the second message including the first message to a plurality of UICCs on the basis of the second message, wherein the plurality of UICCs includes at least one eUICC.

Method and device for transmitting and receiving profile for providing communication service in wireless communication system

Provided are a method for authenticating a user terminal in an interface server, and an interface server and a user terminal using the same. The method includes receiving authentication request information from an application service providing server in order to request the interface server to authenticate the user terminal receiving an application service provided from the application service providing server, authenticating the user terminal according to the authenticating request information using an authentication method selected by the interface server or a user of the user terminal, and transmitting authentication response information including an authentication result of performing the authentication method to the application service providing server. The interface server provides an interface for a network to the application service providing server.

Method for user terminal authentication of interface server and interface server and user terminal thereof
