摘要:
A method and system for supporting a handoff of an MS in a PMIP mobile communication system are provided. The method includes a target node transmitting a first registration request message to an HA in order to request registration of the MS, when the MS moves from the service area of a serving node to the service area of the target node; the serving node discarding a second registration request message without processing the second registration request message, when the serving node receives the second registration request message from the MS before the target node receives a first registration response message for the first registration request message from the HA; and the serving node requesting deregistration of the serving node to the HA, when the target node receives the first registration response message from the HA.

A retransmission method and apparatus in a multi-hop broadband wireless communication system are provided, in which if there is a failed data block among data blocks received from a source node, a Relay Station (RS) transmits a feedback message requesting retransmission of the failed data block to the source node, transmits a successfully received data block to a destination node, receives a retransmitted data block for the failed data block from the source node, transmits the received retransmitted data block to the destination node, receives from the destination node a feedback message about data blocks transmitted to the destination node, and transmits the feedback message to the source node.
摘要:
A handoff method between a source network to which a terminal is connected in order of a Base Station (BS) and an Access Service Network (ASN), and a target network to which the terminal is connected in order of a Packet Data Service Node (PDSN), a Packet Control Function (PCF) and an Access Network (AN). The terminal sends a handoff request message with AN information of the target network to the ASN via the BS. The ASN forwards the handoff request message to the PCF via the PDSN using the AN information. Upon receipt of the handoff request message, the PCF sends a request for session information to the ASN via the PDSN. The PDSN sends a request for context information to the ASN. Upon receipt of the session information request and the context information request, the ASN transfers the context information to the PDSN and transfers the session information to the AN via the PDSN and the PCF.
摘要:
A method and apparatus for performing device authentication and user authentication in a mobile communication network are provided. A connection is established between an MS and an SRNC that controls communications of the MS through a BS. The SRNC receives a D-MSK for device authentication of the MS from an AAA server that has completed an EAP negotiation with the MS and stores the D-MSK by the SRNC, when the BS triggers an EAP authentication after the connection establishment. The SRNC receives an R-MSK from an AG and stores the R-MSK after the connection establishment. The R-MSK is generated using a U-MSK for user authentication of the MS received from the AAA server by the AG. The SRNC generates a PMK for use during a session using at least one of the D-MSK and the R-MSK, and one of the BS and the SRNC generate a key set using the PMK, for use in at least one of data encryption, data integrity check, and session management during the session.
摘要:
A method and an apparatus for effective data sharing between users in a cloud computing system are provided. The cloud computing system includes a first cloud hub and a User Equipment (UE). The first cloud hub provides a cloud service to a UE connected by a public cloud access and provides a cloud service to a UE connected to a public personal cloud system installed by a service provider, and is installed by a user. The UE subscribes to the first cloud hub as a main cloud and inquires as to data stored in the first cloud hub.
摘要:
An apparatus and method for controlling a reverse data rate in a mobile station. The method includes determining whether the mobile station has sufficient power to transmit at an increased data rate compared to a current data rate, and transmitting a determination result to a base station.
摘要:
An apparatus and method for transmitting and receiving packet data in persistent resources in a wireless communication system using Hybrid Automatic Repeat reQuest (HARQ) are provided, in which a user buffer stores user data to be transmitted to a receiver, a controller allocates persistent resources to the receiver according to the data type of the user data and controls a Packet Start Indicator (PSI) to be included in an initial transmission subpacket, when the initial transmission subpacket is transmitted, and a transmission and reception processor transmits the user data and the PSI to the receiver and receives a response signal from the receiver.
摘要:
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.
摘要:
A method and apparatus for setting up an UpLink common bearer shared by a plurality of User Equipments (UEs) in a wireless communication network is provided. The apparatus includes a Serving GateWay (S-GW) for receiving a group identifier of a UE from a Mobility Management Entity (MME), sending a create bearer request message including the group identifier to a Packet Data Network (PDN) GateWay (P-GW), receiving a create bearer response message including UL common S5 bearer information (UL common S5 info) for a group corresponding to the group identifier from the P-GW, and sending a create bearer response message including UL common S1 bearer information (UL common S1 info) to the MME, and the P-GW for receiving the create bearer request message from the S-GW, and generating and sending the create bearer response message including the UL common S5 info.
