The policy may be locally stored within the CGW. Dynamic flow management, load balancing, offloading, PDF context establishment, prioritization, detection of devices, and the like may also be provided and/or implemented in the CG W and may be used to route flows and/or traffic associated with data. | 11-20-2014 |
20150044994 | SYSTEM AND METHOD FOR PROVIDING VARIABLE SECURITY LEVEL IN A WIRELESS COMMUNICATION SYSTEM - A system and method for providing variable security levels in a wireless communication network. The present invention optimizes the often conflicting demands of highly secure wireless communications and high speed wireless communications. According to a preferred embodiment of the present invention, various security sensors are scanned to determine the likely presence of an intruder within a predetermined trust zone. If an intruder is likely present, the security level is changed to the highest setting, and consequently a lower data rate, while the intruder is identified. If the identified intruder is in fact a trusted node, the security level is returned to a lower setting. If the identified intruder is not a trusted node, the security level is maintained at an elevated state while the intruder is within the trust zone. | 02-12-2015 |
20150045032 | METHOD AND APPARATUS FOR OFFLOADING BACKHAUL TRAFFIC - A method and apparatus for offloading backhaul traffic are disclosed. A first base station may detect a condition triggering backhaul traffic offloading for a wireless transmit/receive unit (WTRU). The first base station may establish a wireless connection with a second base station, and offload at least one bearer of the WTRU onto the second base station via the wireless connection. The first base station may be a macro-cell base station and the second base station may be a femto-cell base station having a wired connection to Internet and a mobile operator core network. The first or second base station may include a relay functionality and act as a relay between the WTRU and the other base station. The backhaul link may be established using a Uu, Un, X2 interface or any other interface over a licensed or license-exempt frequency, a TV white space frequency, etc. | 02-12-2015 |
20150074411 | ENHANCED SECURITY FOR DIRECT LINK COMMUNICATIONS - A method and apparatus for secure direct link communication between multiple wireless transmit/receive units (WTRUs) are disclosed. The WTRUs may exchange nonces that are used for generating a common nonce. Group identification information may be generated from at least the common nonce and is forwarded to an authentication server. The authentication server may generate a master key from the group identification information to match WTRUs as part of a key agreement group. The common nonce may be a session key and be refreshed during communication with the second WTRU. A group key encryption key (GKEK) and a group key confirmation key (GKCK) may also be generated based on the common nonce and used to encrypt and sign the master key so that base stations do not have access to the master key. A first WTRU may generate a group direct link temporal key (GDLTK) for communicating with the second WTRU. | 03-12-2015 |
20150085741 | METHOD AND APPARATUS FOR COOPERATIVE WIRELESS COMMUNICATIONS - A method and apparatus for cooperation in wireless communications. Cooperation is considered among a number of network elements, including at least one wireless transmit-receive unit, at least one relay station, and at least one base station. | 03-26-2015 |
