An apparatus for a switch in a communication network includes a controller configured to receive path information of a service flow between a first user equipment (UE) and a second UE from a controller, receive a packet forwarded through the flow from an evolved NodeB and forward the packet to a path determined by the path information. Other embodiments are also disclosed. | 11-20-2014 |
20140341199 | METHOD AND DEVICE FOR PROCESSING SERVICE IN SOFTWARE-DEFINED NETWORKING SYSTEM - A method and device for processing a service in a mobile communication system based on SDN technology are provided. The method of controlling access caches in a communication network includes receiving information about contents requested by a user equipment (UE) connected to a first base station. The method also includes transmitting a forwarding request that requests to control at least one switch in order for an access cache that has the contents and that interworks with a second eNB to transfer the contents to the first eNB. | 11-20-2014 |
20140357231 | METHOD AND APPARATUS FOR SUBSTITUTING FOR AUTHENTICATION AND PAYMENT FOR THIRD PARTY SITE IN A RADIO MOBILE COMMUNICATION SYSTEM - Disclosed is a method of substituting for authentication of subscriber terminals of a mobile communication network for a third party site in a radio mobile communication system, the method including: obtaining traffic information for each subscriber terminal from the mobile communication network to which the subscriber terminals connect; receiving an authentication request for a first subscriber terminal from the third party site that has received a service request of the first subscriber terminal from the mobile communication network; and authenticating, if an IP address of the first subscriber terminal is one of IP addresses of the subscriber terminals contained in the traffic information, the first subscriber terminal using traffic information of the first subscriber terminal, and providing an authentication result to the third party site. | 12-04-2014 |
