20140328319 | METHOD AND APPARATUS FOR ASSIGNING IP ADDRESS IN MOBILE COMMUNICATION NETWORK - When a Mobile Node (MN) is assigned IP addresses, the number of which is greater than or equal to the preset number of IP addresses that the MN is capable of being assigned with, the MN identifies information on the pre-emption vulnerability of each session associated with an IP address, and releases an IP address which enables a disconnection of a session. When there are multiple IP addresses associated with the pre-emptable sessions, a consideration is given to multiple conditions related to which IP address is to be selected, one IP address is selected, and the relevant IP address is released. When any IP address cannot be released, a new session is associated with an IP address which can give the smallest overhead to the MN and the network among the existing IP addresses, so that an IP address can be efficiently assigned. | 2014-11-06 |
20140328320 | DATA TRANSFER MANAGEMENT IN A RADIO COMMUNICATIONS NETWORK - A mobile communications system including a network with a source network node and a target network node that supports a handover procedure, and a mobile terminal that is allowed to access the source network node and access the target network node according to the handover procedure, in which information related to a reception status of user data is delivered between at least two among a group including the mobile terminal, the source network node, and the target network node such that the target network node may receive status information from the source network node and the target network node may receive a status report from the mobile terminal. | 2014-11-06 |
20140328321 | COMMUNICATION SYSTEM AND COMMUNICATION CONTROLLING METHOD - A communication method in LIPA/SIPTO architecture is provided which, when a user equipment (UE) is to connect from a serving area to an external network, allows re-selection of an optimal gateway. The communication method allows selecting a gateway apparatus physically or topologically close to a site, where the user equipment is attached. | 2014-11-06 |
20140328322 | HEADER COMPRESSION OPTISATION METHOD DURING AND AFTER HANDOVERS IN CELLULAR COMMUNICATION NETWORK - The present invention concerns a method for optimizing ROHC RTP (Robust Header Compression Real Time Protocol) compression applied to IP header of data packets stream so as to use more compact formats enable to remain in a steady state, to never discard received packet, and to serve radio resources without requiring to modify ROHC specification. In the method, when handover or mobility procedure is started, new reference values are normally added to a sliding compression window, but no reference value is removed from the window as long as the handover or mobility procedure is on going. After the handover or mobility procedure is complete, when the number of values transmitted on the new radio link are appropriate to cope against the error properties on the new link, all older values can be removed at once from the compression window, thereby reverting to normal window operation. | 2014-11-06 |
20140328323 | Method And System For Single Radio Voice Continuity Handover - A method and a system for single radio voice continuity handover. The method includes: performing communication based on a media codec type negotiated by calling and called parties in a process of handing over a voice service from a first network to a second network, wherein the negotiated media codec type is a media codec type supported by a media gateway. With the above technical solution, the problem of frequently transcoding in the prior art is avoided. | 2014-11-06 |
20140328324 | RADIO BASE STATION AND METHOD OF CONTROLLING TRANSITION BETWEEN RADIO SYSTEMS - A radio base station capable of communication in a first radio system and a second radio system includes a measurement unit arranged to measure a radio wave transmitted from a neighbor radio base station in the first radio system; a configuration unit arranged to configure a measurement criterion whether measurement of a radio wave is needed upon transition from the second radio system to the first radio system based on a measurement result by the measurement unit; and a determination unit arranged to determine whether to make transition accompanied by measurement of the radio wave based on the measurement criterion configured by the configuration unit, when transition from the second radio system to the first radio system is requested. | 2014-11-06 |
20140328325 | RANDOM ACCESS METHOD AND DEVICE IN COGNITIVE RADIO SYSTEM - Various examples of the present disclosure describe a random access method and device in a CR system. The method includes: generating, by a base station device, a spectrum handover command, wherein the spectrum handover command comprises random access backoff time parameter information; and sending, by the base station device, the spectrum handover command to a user equipment in a cell to instruct the UE to initiate, during a spectrum handover procedure, a random access procedure using the random access backoff time parameter information. According to the various examples of the present disclosure, the random access backoff time parameter information is carried in the spectrum handover command, so that a random access conflict is suppressed during the spectrum handover procedure of the CR system. A large number of UEs that intensively perform random access on a target working frequency are pre-dispersed in time. As such, the delay and the failure probability of the random access on the target working frequency during the spectrum handover procedure are reduced, and thus the failure probability of the spectrum handover and the service interruption time are reduced, so that the user experience of the CR system is improved. | 2014-11-06 |
