20100157953 | CONTINUOUS PACKET CONNECTIVITY (CPC) SCHEDULER - A base station establishes a data channel in an uplink between the base station and a user equipment, establishes a control channel in the uplink between the base station and the user equipment, and determines a gating configuration associated with the control channel. The base station also transmits the gating configuration to the user equipment, receives a gated control signal, via the control channel, based on the gating configuration, and synchronizes time slots for signal bursts associated with the gated control signal and time slots for data packets associated with the data channel. The base station further schedules transmissions of the data packets based on the synchronized time slots, generates an absolute grant based on the scheduled transmissions of the data packets, and transmits the absolute grant to the user equipment. | 06-24-2010 |
20110044305 | CHANNEL DEPENDENT GATING - Network element ( | 02-24-2011 |
20110076969 | Gating Control Loop - The present invention is about tuning the gating scheme according to the performance of the application used. This can mean that in some situations gating is not used at all while in other occasions gating is used where the cycle length, burst length, number of preambles and offset are adjusted. The performance is monitored and the gating is increased or decreased depending on the results of the monitoring and demands of the application. Furthermore, the gating scheme adapts to the current performance and is chosen to optimize performance in terms of system capacity. The monitoring also takes into account which of the gating cycles that needs to be changed. The algorithm is self tuning/configuring meaning that it will control the gating scheme to find and keep an optimal level for the used application. The method may be implemented both in a mobile terminal (UE) and in an infrastructure node (BS) and executed by instruction sets belonging to a computer program. | 03-31-2011 |

20110299485 | Apparatus and Method for Controlling User Equipment State Changes - The present invention relates to an apparatus and method for triggering change of a Radio Resource Control (RRC) state for a user equipment operating in a cellular network. According to the method a Radio Link Control (RLC) buffer threshold associated with a Radio Link Control buffer is set to an initial value upon the user equipment entering a CELL_FACH RRC state. The RLC buffer threshold is decreased as a function of time. A RRC state change for the user equipment between the CELL_FACH RRC state and a CELL_DCH RRC state is triggered according to a predetermined rule based on a current size of the RLC buffer and the RLC buffer threshold. The method facilitates achieving a desired RRC state transition behavior for some types of users. | 12-08-2011 |

20140082320 | STATE MEMORY MANAGEMENT - The present invention relates to management of a state memory in a communications unit. The state memory then stores states that are used in message-based communication with external units in a communications system. The data message communicated between the units are defined into multiple message classes. Furthermore, the state memory is divided into multiple memory portions, where each such memory portion is assigned to store states associated with a specific message class. This will prevent overwriting important states with less useful states. | 03-20-2014 |

20140235257 | Controlling Fast Dormancy - A user equipment, UE, in a radio communication network is given a threshold time value that the UE uses to decide whether it should trigger a fast dormancy request to a network node or not. The determination of the threshold time value can be adapted so that it minimizes UE battery consumption when the load in the network node is low and at other times minimizes the load on the network node. That is, if the UE estimates that a predicted time interval until reception of a data burst is less than threshold time value it will not trigger a fast dormancy request, and if the estimated time interval is larger than the threshold time value it will trigger a fast dormancy request. Since the network typically controls state switching, there is a large benefit for the UE to comply with the scheme, otherwise the network may not obey the UEs wish to be down switched by the fast dormancy request. | 08-21-2014 |
