The invention discloses a method and a device for reading data, which belong to the technical field of computers. The method comprises the following steps: determining a head-pointer position and a tail-pointer position of a channel; comparing the height of the head-pointer position and the height of the tail-pointer position; and sequentially reading a data packet according to a comparison result. The device comprises a determining module, a comparing module and a reading module. According to the invention, through sequentially reading the data packet, the times for reading the data can be reduced; and in addition, since the times for reading the data is reduced, the efficiency for reading the data can be improved, and thus the probability that data overflow from the channel is reduced.

A cellular telecommunications network includes a method for messaging across a lossy interface. The method includes transmitting a control information entity having a control message (110, 130). The method also includes monitoring for reception of a data information entity of a certain type (120, 140). The method also includes, if a data information entity of a certain type is not received within a predetermined time period (140), retransmitting of the control information entity having a control message (150). In an embodiment, a capacity allocation message transmitted from a node B to an RNC is acknowledged with a data packet with empty payload or with an indication in the header indicating that the capacity allocation message was received.

The invention discloses a configurable dynamical time slice round-robin scheduling algorithm, which is applicable to the condition that a plurality of on-line tracking units in an on-line tracking system need to carry out data output through a single transmission interface. According to the algorithm, through configuring a corresponding threshold value, time slice length and priority, judgments in active states of the on-line tracking units are combined, and the data output request of each on-line tracking unit is arbitrated by adopting two inquiry ways. By using the configurable dynamical time slice round-robin scheduling algorithm, the synthesis on a plurality of ways of track data can be realized on premises of a low resource consumption, a low data overflow rate and a high expandability, so as to solve the scheduling problem of a plurality of data cache queues in the on-line tracking system.

The invention discloses a multi-channel power distribution method driven by a sustainable transmission demand in an energy collecting wireless network. The method comprises the following steps: 1) setting a data queue index ThetaD and an inversion energy queue index ThetaE according to the sustainable transmission demand, and initializing system parameters; 2) entering a transmission period, acquiring electric quantity information and limiting the total transmission power maximum value Mumax based on state information sequence of N channels; 3) solving the optimal total transmission power Mu*and like; 4) distributing the optimal transmission power as shown in description of each channel, and transmitting formula as shown in description paths of independent data flows to a receiver; 5) updating Lagrangian multiplier Lambda; and 6) entering the next transmission period, and repeating the steps 2) to 5) until the transmission is finished. The multi-channel power distribution method disclosed by the invention is suitable for cache capacity limited equipment in the energy collecting wireless communication system, and the cache capacity limitation of a transmitter and a battery interruption probability limitation under the energy collection are taken into consideration at the same, so that the power self-adaptive distribution scheme of the system capacity is maximized in the premiseof ensuring that the cache overflow probability and the battery interruption probability satisfy the sustainable transmission demand.
