A device receives available capacity and used capacity associated with a network, receives a connection request from a user device in the network, and receives a maximum capacity threshold associated with the network. The device calculates a minimum capacity threshold and a medium capacity threshold, associated with the network, based on the maximum capacity threshold. The device also determines whether to admit or deny the connection request based on the available capacity, the used capacity, the minimum capacity threshold, the medium capacity threshold, and the maximum capacity threshold. The device further allocates, when the connection request is to be admitted and based on resource availability associated with the network, a particular bit rate, for a particular quality of service (QoS) class, to the connection request.

Method of channel management for multiple component carrier in mobile communication system

Номер: US20120039200A1

Принадлежит: Electronics and Telecommunications Research Institute ETRI

Disclosed are channel management methods in a multicarrier structure in a mobile communication system. Uplink (UL) and downlink (DL) channel management methods in a carrier aggregation environment are used as the channel management methods. In DL, a base station determines a component carrier (CC) of an unstable radio channel state, stops data retransmission by the CC, and notifies a terminal of retransmission stop. In UL, the base station determines a CC of an unstable radio channel state and instructs the terminal to stop data retransmission by the CC, and the terminal stops the data retransmission and initializes a retransmission buffer. Using the channel management methods in the mobile communication system employing the multicarrier structure, an increase in the number of unnecessary retransmissions is prevented, so that unnecessary retransmission and power consumption of the terminal can be reduced and the waste of radio resources and the degradation of base station performance due to unnecessary retransmission can be prevented.

Mechanism to update a nav timer

In a 60 Hz WGA wireless network, not all frames with the duration field are received by a STA in a WGA network because of directional antennas. Therefore, a NAV Timer cannot account for the reserved duration of the channel by only updating with the longest duration field received. A STA can receive two frames each with a source and destination addresses and update the NAV Timer by comparing the received addresses to overcome such problem. Further, a STA can receive one frame with a source and destination addresses and update the NAV Timer by comparing the received addresses with the NAVSRC and NAVDST values.

A method and circuit for implementing lane shuffle for fault-tolerant communication links, and a design structure on which the subject circuit resides are provided. Shuffle hardware logic steers a set of virtual data lanes onto a set of physical optical lanes, steering around all lanes that are detected as bad during link initialization training. A mask status register is loaded with a mask of lane fail information during link training, which flags the bad lanes, if any. The shuffle hardware logic uses a shift template, where each position in the starting template is a value representing the corresponding lane position. The shift template is cascaded through a set of shifters controlled by the fail mask.

Messages transmitted between a receiver and a transmitter are used to maximize a communication data rate. In particular, a multicarrier modulation system uses messages that are sent from the receiver to the transmitter to exchange one or more sets of optimized communication parameters. The transmitter then stores these communication parameters and when transmitting to that particular receiver, the transmitter utilizes the stored parameters in an effort to maximize the data rate to that receiver. Likewise, when the receiver receives packets from that particular transmitter, the receiver can utilize the stored communication parameters for reception.

Link adaptation parameters for encoding of a source are selected to minimize distortion between the source and a reconstructed source induced by transmission of the source over a multiple input multiple output (MIMO) channel. Such distortion-awareness and associated joint source-channel coding ideas to support link adaptation over MIMO channels may affect system architectures for MIMO systems. CQI feedback mechanisms may ensure that these distortion-aware MIMO link adaptation techniques are applicable for downlink channels, under different forms of link adaptation, including MS-controlled vs. BS-controlled link adaptation, long-term vs. dynamic link adaptation, and presence vs. absence of distortion-awareness at the BS, for different kinds of video coding including single-layer compression and layered compression.

Methods and systems are described for providing a presence service that is useful for mobile telecommunications devices. A plurality of outgoing presence updates are sent to a presence client. The system monitors the level of network traffic and determines whether the client is in a region of high network load, and if so, the system throttles the outgoing presence updates during the condition of high network load. The level of throttling may depend at least in part on the amount of time that has elapsed since the presence client began a presence session, and/or the amount of time that has elapsed since an incoming presence update was received from the presence client. In determining the latter amount of elapsed time, the system may consider only the amount of time elapsed since an incoming non-automatic presence update was received from the presence client.

Принадлежит: Motorola Inc

A method is provided to determine optimal data rate and packet length in mobile networks. The method directly determines the optimal packet length (L) and data rate (D), which allows fast convergence in the mobile channel. The method automatically identifies and quantifies channel conditions, as well as adjusts parameters according to changes of channel conditions. A variable (Channel condition Index (CCI)) is abstracted from simulations and then used to describe and quantify the impact of three components of channel conditions: signal-to-noise ratio (SNR), multipath environment and velocity. Based on packet completion rate (PCR) status, the channel condition is identified in terms of CCI value. Once CCI is identified, the model of effective throughput G is directly optimized to locate the best packet length (L) and data rate (D).

A network module can determine the source destination, and a priority of a packet based on the packet's content. Using the source and destination information, along with a network topology data, the network module can determine if two packets need the same network resources to be delivered to their destination. When the two packets do not use the same resources, there is no conflict, and the packets can be transmitted concurrently regardless of whether one of the packets has a higher priority than another packet. If there is a conflict, the network module transmits the packets based on the packets' priorities.

The method comprises the steps of receiving ( 101 ) the mobile terminal information from the base station indicating available system carriers; detecting ( 102 ) at least one dynamic parameter indicative of the mobile terminal's current capability to handle non-contiguous system carriers; determining ( 103 ) from the dynamic parameter whether a situation has occurred where the mobile terminal's capability to handle non-contiguous system carriers has been reduced; modifying ( 104 ), in such case, feedback information to be transmitted to the base station; and transmitting ( 105 ) the modified feedback information to the base station. By modifying the feedback information in this way the mobile terminal reduces the likelihood that the base station allocates non-contiguous system carriers to the mobile terminal in situations where it has a reduced capability of handling such system carriers.
