20100232606 | METHOD AND SYSTEM FOR AUTHENTICATING IN A COMMUNICATION SYSTEM - A method and system for authenticating in a communication system are provided. The method includes, in a first authenticator, sending an authenticator relocation request to a second authenticator transmitting a hash value for an authentication parameter of a Mobile Terminal (MT), a random parameter | 09-16-2010 |
20110076987 | METHOD AND SYSTEM FOR CHANGING ACCESS SERVICE NETWORK OF MOBILE STATION IN COMMUNICATION SYSTEM - A method and a system for relocating an Access Service Network (ASN) of a Mobile Station (MS) in a communication system are provided. In the method, when an MS that operates in an idle mode moves from a first ASN to a second ASN, the MS transmits a ranging request message to a base station of the second ASN in order to update a location. The base station transmits a location update request message to an ASN-GateWay (GW) of the second ASN according to the ranging request message. When the location update request message is received, the ASN-GW transmits a relocation notify message including type information for location update to the first ASN. The first ASN transmits a relocation notify response message including paging information to the ASN-GW according to the relocation notify message. | 03-31-2011 |
20110129088 | METHOD AND SYSTEM FOR AUTHENTICATING A MOBILE TERMINAL IN A WIRELESS COMMUNICATION SYSTEM - A method and system for authenticating in a wireless communication system. The system includes a Mobile Terminal (MT), an authenticator, and an Authentication, Authorization, Accounting (AAA) server. When the authenticator requests NAI information for authentication, the MT adds an authentication code to the NAI, and sends a response message including the NAI information to the authenticator. The authenticator relays the NAI to which the authentication code is added, to the AAA server. The AAA server extracts the authentication code from the NAI information, verifies the authentication of the MT, generates a new authentication key, and transmits the new authentication key to the authenticator. | 06-02-2011 |
20120159167 | METHOD AND APPARATUS FOR AUTHENTICATING PER M2M DEVICE BETWEEN SERVICE PROVIDER AND MOBILE NETWORK OPERATOR - A system is capable of authenticating a service per Machine to Machine (M2M) device between an M2M service provider and a mobile communication operator. The system includes an authentication server for generating an M2M device IDentifier (ID), a first authentication key, and an M2M service provider ID per M2M device, The authentication server also generates a second authentication key, a first hash function value, and a first random variable based on the M2M device ID, the first authentication key, and the M2M service provider ID. and transmitting the second authentication key, the first hash function, and the first random variable to an M2M agent to an M2M agent. | 06-21-2012 |
20120196566 | METHOD AND APPARATUS FOR PROVIDING QOS-BASED SERVICE IN WIRELESS COMMUNICATION SYSTEM - A method and an apparatus for providing a Quality of Service (QoS)-based service in a wireless communication system are provided. The method includes providing a Mobile Station (MS) with at least one QoS plan indicating a price policy for a QoS acceleration service having a higher QoS than a default QoS designated for a user of the MS in response to a request from the MS, providing the MS with an authorized token and a QoS quota based on a selected QoS plan in response to a purchase request of the MS, providing the MS with service contents selected by the user through a radio bearer for the QoS acceleration service, notifying the MS, if a usage of the QoS acceleration service reaches a threshold, of an impending expiration of the QoS acceleration service, and notifying the MS of the expiration of the QoS acceleration service. | 08-02-2012 |
20120204027 | AUTHENTICATION METHOD AND APPARATUS IN A COMMUNICATION SYSTEM - An authentication method and apparatus in a communication system are provided. In a method for authenticating a first node at a second authentication server in a communication system comprising the first node registered to a first authentication server and a second node registered to the second authentication server, an authentication request message requesting authentication of the first node is received from the second node, the authentication request message is transmitted to the first authentication server, and upon receipt of an authentication success message indicating successful authentication of the first node from the first authentication server, the authentication success message is transmitted to the second node. | 08-09-2012 |
20120265979 | MACHINE-TO-MACHINE NODE ERASE PROCEDURE - A method for erasing bootstrapping, at a device or a gateway in a Machine-to-Machine (M2M) service is provided. The method includes receiving an erase request containing a first M2M-Erase-Token from an M2M Authentication Server (MAS) or an M2M Service Bootstrapping Function (MSBF), processing the erase request based on the first M2M-Erase-Token or a local policy of the device or the gateway, and sending an erase response containing a second M2M-Erase-Token to the MAS or the MSBF. | 10-18-2012 |
20150032906 | APPARATUS AND METHOD FOR ASSIGNING IP ADDRESS IN COMMUNICATION SYSTEM - A method for selecting a source address in a host electronic device is provided. The method includes determining an address type to use in communication of an application which is being executed, selecting a source address based on the determined address type, and setting the selected source address as a source Internet Protocol (IP) address for a transmission packet of the application which is being executed. | 01-29-2015 |
