20090262685 | METHOD AND APPARATUS FOR MOBILE IP ROUTE OPTIMIZATION - The current application concerns a method, mobile node, home agent and system for route optimisation between a mobile node and at least one correspondent node in a packet switched network, wherein a route via a first home agent is redirected via a second home agent. The mobile node sends an extended home test initiation message comprising following information: authentication data, an address of the correspondent node, a first home address and a second home address. The first home agent receives the extended home test initiation message and sends an extended home test message to the second home agent, the extended home test message comprising the information from the extended home test initiation message. The second home agent receives the extended home test message and a communication is routed between the mobile node and the at least one correspondent node via the second home agent. | 10-22-2009 |
20100002652 | MOBILE COMMUNICATION METHOD AND ACCESS ROUTER - A technology is disclosed in which, when a normal mobile node (that does not newly provide a dedicated function) is used, signaling for reconfiguring a tunnel during a mobile node movement is reduced and, furthermore, packet loss is reduced. In the technology, when an MN moves from under the control of an AR | 01-07-2010 |
20120020343 | GATEWAY CONNECTION METHOD, GATEWAY CONNECTION CONTROL SYSTEM, AND USER EQUIPMENT - Disclosed is a technique in which when mobile terminal having multiple communication interfaces attaches to an access network, the mobile terminal can connect to a desired PGW quickly in a short time even if a PGW different from the desired PGW is allocated. According to the technique, when a mobile terminal (UE) | 01-26-2012 |
20130042011 | COMMUNICATION NODES AND NETWORK NODES - Disclosed is a technique for reducing the number of event report messages sent from many communication nodes (MTC devices). Upon detecting an event (smoke detection by a smoke sensor), an MTC device A | 02-14-2013 |

20140016614 | SHORT MESSAGE TRANSMISSION AND HANDOVER PROCEDURES - The present invention relates to an improved method for handover of a mobile node from E-UTRAN to UTRAN in a scenario where SMS is the only service of the mobile node. The improved handover method allows saving radio resources by establishing the signalling connection for SMS exchange in the target network, and avoiding the data connection in the target network, since it is not used. The MME takes the decision to establish or not the data connection in the target UTRAN, and accordingly instructs the SGSN and UE to set the corresponding PDP contexts for the data connection to a “preserved” state, so as to avoid the establishment of same. Embodiments further relate to improved SMS delivery for IDLE mode UEs that activate ISR so as to avoid the involvement of the MSC server. Instead, packet-switched domain nodes are to be involved only. | 01-16-2014 |
20140177583 | SERVER AND COMMUNICATION TERMINAL - Disclosed is a technique for reporting the IP address of a UE using a response message to a device trigger. A control message receiving unit receives, from a network, a control message generated based on a trigger request message transmitted from the predetermined communication device for requesting the transmission of the control message to a communication terminal. A determining unit determines whether to perform communication with the predetermined communication device using an IP packet. A connection management unit acquires an IP address allocated to an IP connection used in communication with the predetermined communication device when determining to perform the communication using the IP packet at the time of receiving the control message at the control message receiving unit. A response message transmitting unit transmits a response message to the control message to the network, where the response message includes the IP address acquired by the connection management unit. | 06-26-2014 |
20160112897 | METHOD FOR MANAGING OVERLOAD IN A MOBILE COMMUNICATION NETWORK - A mobile communication network (MCN) and method for managing (overload in) an MCN having a radio access network and core network connected to the radio access network, wherein a plurality of user devices in form of non-MTC user devices like mobile phones and MTC user devices is connected to base station(s) of the radio access network, includes: a) detecting a presence of a network overload in the MCN, b) generating an overload report according to the detected network overload comprising one or more resource identifiers of the resources of the MCN on which the overload was detected, e) identifying (WI) user device(s) (UD) and/or application(s) affected by the network overload (OL) based on the overload report, and d) informing one or more serving entities serving the resolved UD for temporarily suppressing communication requests, preferably in form of devices triggers (DT), for the resolved UD, preferably MTC UD. | 04-21-2016 |
