20090052453 | Method and apparatus for improving the performance of voice over IP (VoIP) speech communications systems which use robust header compression (RoHC) techniques - A method and apparatus for use in improving the performance of Voice over Internet Protocol (VoIP) communication systems which use Robust Header Compression (RoHC) techniques for reducing communications protocol overhead. Specifically, having recognized that in VoIP applications (unlike, for example, data services applications), severely late packets cannot be used, a “RoHC-Guard” filters out packets that are very late, making it impossible for RoHC to perform the costly and unnecessary re-sync. In accordance with one embodiment of the invention, a RoHC-Guard module, operating as a pre-filter to a RoHC module, saves, rather than merely discards, late packets. Then, if a predetermined number of such packets are consecutively received, they are provided to RoHC module. | 02-26-2009 |
20090175225 | Method of wireless data transmission - In one embodiment the method includes allocating, for a mobile, forward link resources for transmitting data over a shared forward link data channel without allocating reverse link resources for reverse link data transmission in association with the allocated forward link resources. At least a portion of the received data is repeatedly sent to the mobile on the shared forward link data channel over a time division multiple access air interface using the allocated forward link resources until an acknowledgement is received from the mobile or a number of transmissions have taken place. | 07-09-2009 |
20090190475 | METHOD OF PRIORITIZING USER THROUGHPUT AND USER THROUGHPUT LIMITS FOR BEST-EFFORT APPLICATION IN cdma2000 1xEV-DO WIRELESS COMMUNICATION SYSTEM - The present invention provides a method implemented in a mobile unit configured to communicate with at least one base station over an uplink. The method includes receiving, at the mobile unit and from the base station, a first attribute indicative of a traffic-to-pilot power ratio and a second attribute indicative of a resource provision limit. The first attribute is formed based on a priority weight associated with best effort communication with the mobile unit. The second attribute is formed based on a maximum throughput associated with best effort communication with the mobile unit. The method also includes modifying an uplink transmission power based upon the first attribute and information indicative of congestion at the base station. | 07-30-2009 |
20100008229 | Method and system for joint reverse link access and traffic channel radio frequency overload control - A system for joint reverse link access and traffic channel overload control in a cellular network includes relieving the reverse link total loading to optimize resource utilization and distribution among different types of mobile device users. The cellular network includes a plurality of mobile stations that wirelessly communicate with a base station over a reverse link, using a CDMA or similar communications protocol. A joint access and traffic overload control module creates an access channel load relief plan, a traffic channel load relief plan and then relieves the total loading of the reverse link based upon both the access channel load relief plan and the traffic channel load relief plan. | 01-14-2010 |

20100177706 | Method of handling transmission of data to a mobile device through multiple channels - Example embodiments provide methods of handling transmission of data to a mobile device through multiple channels. One example embodiment includes receiving carrier capacity values from each of a plurality of carrier controllers providing communication for a mobile device over corresponding channels, the carrier capacity values being an estimate of the number of bytes that the carrier controller can send to the mobile device on time; receiving data for the mobile device; and sending the data to the plurality of carrier controllers, the amount of the data sent to each of the carrier controllers being based on the carrier capacity value received from each of the plurality of carrier controllers. | 07-15-2010 |
20100309814 | ALLOCATING INTERLACE MULTIPLEX PAIRS FOR MULTICAST SERVICES - The present invention provides a method implemented in a control entity within a wireless communication system. The method includes selecting, at the control entity, a plurality of sectors in response to receiving requests for a multicast service from mobile units located within the plurality of sectors. The method also includes allocating, at the control entity, one or more interlace-multiplex pairs for providing the multicast service to the mobile units within the plurality of sectors. One or more of the interlace-multiplex pairs are allocated based on a priority list that ranks priorities of the plurality of interlace-multiplex pairs according to how many of the plurality of sectors provide the multicast service using the corresponding interlace-multiplex pair. The method also includes establishing a call flow over an air interface to the mobile units using the allocated interlace-multiplex pair(s). | 12-09-2010 |
20110124332 | System and method for load balancing among multiple base stations using network initiated handovers - The present invention relates to a system and method for load sharing among multiple base stations using Network Initiated Handover (NIHO). In one embodiment, the method includes computing scores for qualified pairs of candidate mobile station and target base station for potential network initiated handover (NIHO), and selecting a pair of candidate mobile station and target base station based on the computed scores to handover the candidate mobile station of the selected pair from the serving base station to the target base station of the selected pair. | 05-26-2011 |

The downlink SIR is determined based on a channel quality indication (CQI) index received from the user equipment. | 07-28-2011 |
20120208545 | Method For Reduced-Overhead Short Message Transmission - For applications with very small data activities, connection of a UE to a wireless network for sending or receiving such small data traffic increments via conventional connection set-up processes is quite inefficient in terms of spectral resource utilization. The invention provides a new connectionless methodology for transmission of such small data increments between a UE and a serving eNB. In particular, the invention methodology contemplates identifying a set of preamble sequences among the pool of preamble sequences provided for access requests from a UE to an eNB via the Random Access Channel as corresponding to a request from the UE for access to transmit an increment of data smaller than a predetermined threshold data size. When a UE has data traffic to transmit of a size smaller than the predetermined threshold size, it selects one of the preamble sequences in the identified set and sends an access request, using the selected preamble sequence, to a serving eNB via the Random Access Channel. Upon receipt of the access request from the UE, the eNB determines an appropriate RF resource for the data increment sought to be transmitted by the UE, based on the use of the selected preamble sequence sent by the UE, and schedules an uplink connection for the transmission of that data increment by the UE. | 08-16-2012 |
20130195049 | Radio Resource Control Connection Release For User Devices Out Of Up Link Time Alignment - An example wireless communication system includes a wireless access device and a wireless access point. The wireless access device is configured to receive a radio resource control connection release message while in a non-time aligned state, the non-time aligned state being characterized by a lack of up link channel control by the wireless access device. The wireless access point is configured to transmit the radio resource control connection release message when the wireless access point determines that a radio resource control connection to the wireless access device should be released and the wireless access device is in the non-time aligned state. | 08-01-2013 |
