摘要:
Disclosed is a system and a method for communication using different IPs, i.e. a mobile IP supporting mobility and a simple IP, according to the service by a UE. The method includes network initiated IP allocation (i.e. the network allocates different IPs to the UE) and UE initiated IP allocation (i.e. the UE directly requests an IP corresponding to a specific service). As such, the IP is selected and used based on consideration of continuity of the service to be supported by the UE.

An apparatus and method are provided for changing network interfaces in a multiaccess mobile terminal in a wireless communication system including a server for providing high-capacity data transmission service to a mobile terminal, and the terminal for receiving data from the server and supporting various network interfaces. Upon detecting handoff based on current air information received, an interface module reports a change in interface to a new air interface to an upper layer, and manages the mobile terminal such that traffic is transmitted to the new air interface. Upon receiving information on the new air interface from the interface module, a service module determines a bandwidth of the new air interface, generates a message based on the determined bandwidth, and transmits the generated message.
摘要:
An apparatus and a method support Machine to Machine (M2M) communication in a communication system. A method for providing an M2M service includes determining at least one of identifier (ID) information of an M2M device, ID information of an M2M Service Provider (MSP), and service type information of the M2M device to provide the M2M service. The method also includes determining a profile of the M2M device using the at least one information determined. The method further includes transmitting the profile of the M2M device to an Authentication, Authorization and Accounting (AAA) server.
摘要:
An apparatus and method for performing local routing in a mobile communication system. In accordance with the method, if a flow between a first Mobile Station (MS) and a second MS is a local routing candidate, an Access Serving Network GateWay (ASN-GW) receives an AAA request message including information indicating start of local routing from an Authorization, Authentication and Accounting (AAA) server, and performs the local routing between the first MS and the second MS after transmitting to the AAA server an AAA response message including information indicating that the local routing will start in response to the AAA request message. The local routing is based on consent among entities involved in the local routing.
摘要:
In a communication system, second encryption information is generated using first encryption information when data to be transmitted is generated. The data is encrypted using the second encryption information and third encryption information. A signal including the encrypted data and the first encryption information is generated and transmitted.
摘要:
An authentication system and method in a communication system are provided. The authentication system includes an authenticator for receiving from a first Foreign Agent (FA) a location change notification notifying that an Mobile Station (MS) has moved to the service area of the first FA, after the MS completes initial access to a second FA using an authentication scheme with an Authorization, Authentication and Accounting (AAA) server in the service area of the second FA; and transmitting to the first FA a first key and a second key of the MS generated during the initial access of the MS in response to the location change notification.
摘要:
An authentication method and system in a communication system are provided. An MS, a BS and an AAA server acquire a first MSK by a first EAP authentication for the MS in an EAP-in-EAP scheme. After the first EAP authentication, they acquire a second MSK by a second EAP authentication for the MS in the EAP-in-EAP scheme.
摘要:
A method for providing Location Based Services (LBS) in a mobile communication system is provided. Upon receipt of a location trigger for requesting location information of a Mobile Station (MS) from a location client, a Location Server (LS) transmits an authentication request message for requesting an identifier (ID) of an anchor authenticator for the MS to an Authorization, Authentication and Accounting server (AAA). Upon receipt of the authentication request message, the AAA transmits an authentication response message including an ID of the anchor authenticator to the LS. Upon receipt of the authentication response message, the LS transmits a Location Controller Identifier (LCID) request message for requesting an LCID of a Location Controller (LC) for the MS to the anchor authenticator. Upon receipt of the LCID request message, the anchor authenticator transmits an LCID response message including an LCID of the serving LC to the LS. Upon receipt of the LCID response message, the LS transmits a location report request message for requesting a report on location information of the MS to the serving LC. Upon receipt of the location report request message, the serving LC transmits a location report response message including location information of the MS to the LS.
摘要:
An apparatus and method for supporting a location update registration process used for an idle mode operation of a Mobile Station (MS) in a Machine-to-Machine (M2M) communication are provided. The method includes determining whether a system global location update registration timer is applied to the MS, when it is determined that the global location update registration timer is not applied, determining a timer for updating a location when the MS operates in an idle mode, and transmitting a message including the timer to the MS.
摘要:
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.
