20110013598 | PERFORMING PROCESSING WITH RESPECT TO AN OVERHEAD MESSAGE FOR A MOBILE STATION IN TUNNEL MODE - A mobile station determines whether the mobile station is receiving an overhead message in tunnel mode during a handover procedure of the mobile station from a source wireless access network to a target wireless network. The source and target wireless access networks are according to different technologies. In response to determining that the mobile station is in the tunnel mode, tunnel mode processing of the overhead message is performed. In response to determining that the mobile station is not in the tunnel mode, different processing of the overhead message is performed. | 01-20-2011 |
20110032904 | METHOD AND APPARATUS TO CONTROL HANDOFF BETWEEN DIFFERENT WIRELESS SYSTEMS - A wireless communications network includes a first base station system that performs wireless communications according to a first protocol (e.g., 1xEV-DO protocol) and a second base station system that performs wireless communications according to a second, different protocol (e.g., IS-2000). A link is provided between the first and second base station systems to enable a network-initiated handoff procedure. If a source base station system detects that a handoff of a mobile station to a target base station system is required, the source base station system exchanges messaging over the link with the target base station system to perform the handoff. In one example, the handoff is a hard handoff. | 02-10-2011 |
20110038308 | FORMING SPATIAL BEAMS WITHIN A CELL SEGMENT - To perform wireless communications in a wireless network, at least two spatial beams are formed within a cell segment, where the at least two spatial beams are associated with different power levels. The at least two spatial beams are swept across the cell segment according to a sweep pattern. In some implementations, multiple antenna assemblies can be used, where each antenna assembly has plural antenna elements. A lower one of the antenna assemblies can be used to form high and lower power beams, and an upper one of the antenna assemblies can be used to communicate backhaul information, for example. | 02-17-2011 |
20110286349 | Method and System for User Equipment Location Determination on a Wireless Transmission System - Neighbor cell hearability can be improved by including an additional reference signal that can be detected at a low sensitivity and a low signal-to-noise ratio, by introducing non-unity frequency reuse for the signals used for a time difference of arrival (TDOA) measurement, e.g., orthogonality of signals transmitted from the serving cell sites and the various neighbor cell sites. The new reference signal, called the TDOA-RS, is proposed to improve the hearability of neighbor cells in a cellular network that deploys 3GPP EU-TRAN (LTE) system, and the TDOA-RS can be transmitted in any resource blocks (RB) for POSCH and/or MBSFN subframe, regardless of whether the latter is on a carrier supporting both PMCH and POSCH or not. Besides the additional TDOA-RS reference signal, an additional synchronization signal (TDOA-sync) may also be included to improve the hearability of neighbor cells. | 11-24-2011 |
20140050103 | MOBILE PROXY FOR CLOUD RADIO ACCESS NETWORK - Embodiments of computer-implemented methods, systems, computing devices, and computer-readable media are described herein for monitoring, by a mobile proxy associated with a control system of a cloud radio access network (“C-RAN”), application layer data traffic between the control system and a wireless communication device. In various embodiments, the mobile proxy may, based on the monitoring, facilitate alteration of data plane or control plane processing by the wireless communication device or a remote radio head (“RRH”) associated with the C-RAN. | 02-20-2014 |
20140241315 | RADIO ACCESS NETWORK (RAN) FOR PEER-TO-PEER (P2P) COMMUNICATION - A serving gateway (S-GW) in a radio access network (RAN) server system for peer-to-peer (P2P) communication can include a P2P content manager. The P2P content manager can be configured for receiving P2P data content from other nodes in a P2P network, forwarding the P2P data content to other nodes in the P2P network, and transmitting the P2P data content to a mobile device associated with the S-GW in a downlink (DL) transmission. The serving gateway can be a node in the P2P network and coupled to a transmission station in the RAN. The P2P data content includes at least one P2P data packet. | 08-28-2014 |
20150016413 | APPARATUS, SYSTEM AND METHOD OF LAWFUL INTERCEPTION (LI) IN A CELLULAR NETWORK - Some demonstrative embodiments include devices, systems and/or methods of Lawful Interception (LI). For example, a device may communicate a message addressed to an Evolved Node B (eNB) over a cellular communication core network, the message including a Lawful Interception (LI) Information Element (IE) indicating that content corresponding to one or more User Equipment (UEs) connected to the eNB is to be subject to LI. | 01-15-2015 |
20150045057 | Method and System for User Equipment Location Determination on a Wireless Transmission System - Neighbor cell hearability can be improved by including an additional reference signal that can be detected at a low sensitivity and a low signal-to-noise ratio, by introducing non-unity frequency reuse for the signals used for a time difference of arrival (TDOA) measurement, e.g., orthogonality of signals transmitted from the serving cell sites and the various neighbor cell sites. The new reference signal, called the TDOA-RS, is proposed to improve the hearability of neighbor cells in a cellular network that deploys 3GPP EUTRAN (LTE) system, and the TDOA-RS can be transmitted in any resource blocks (RB) for PDSCH and/or MBSFN subframe, regardless of whether the latter is on a carrier supporting both PMCH and PDSCH or not. Besides the additional TDOA-RS reference signal, an additional synchronization signal (TDOA-sync) may also be included to improve the hearability of neighbor cells. | 02-12-2015 |
