Method, equipment and terminal for establishing uplink synchronization in multi-cell long-term evolution system

The invention discloses a method, equipment and terminal for establishing uplink synchronization in a multi-cell long-term evolution system, wherein the method can be used for reducing the control channel spending of the system, increasing the resource utilization rate, shortening the waiting time required for performing uplink and downlink data transmission between the terminal and a base station and guaranteeing the service normal operation. The method for establishing the uplink synchronization in the multi-cell long-term evolution system, provided in the embodiment of the invention comprises the following steps: the base station sends an activating / deactivating command to the terminal so as to inform the terminal to initiate a random access process on an appointed secondary cell in activated secondary cells while activating one or more secondary cells in a terminal TA (Timing Advance) group, wherein an random access command is carried in the activating / deactivating command; and, after the appointed secondary cell is activated, the terminal instantly executes the random access process of the appointed secondary cell and the base station according to the received random access command so as to establish the uplink synchronization.

Event triggering mechanism-based fault detecting method for networked systems

The invention discloses an event triggering mechanism-based fault detecting method for networked systems and belongs to the field of the networked systems. The method comprises the steps of firstly, establishing a continuous time networked system model under the circumstances that sensor saturation, disturbance and fault exist, solving the problem of limited actual network bandwidth by introducingan effective event triggered communication transmission strategy, designing a fault detecting filter and introducing a residual evaluation mechanism to judge whether a system is faulty or not; obtaining sufficient conditions for the asymptotic stability of a filter error system and the existence of the fault detecting filter by adopting a Lyapunov stability theory and a linear matrix inequality analysis method; and solving an optimization problem by utilizing a Matlab LMI toolbox to obtain an optimal fault detecting filter parameter which is shown in the specification. The method disclosed bythe invention has the beneficial effects that the problems that the network bandwidth is limited, sensors are restrained by saturation and faults occur, which exist in the systems in actual situations, are considered; and the method is suitable for the general fault detection and has good universality.

Available bandwidth detecting method, system and device

The invention discloses a usable bandwidth measuring method which comprises the following steps: usable bandwidth measuring precision and usable bandwidth measuring range are received; when the usable bandwidth measuring range is greater than the usable bandwidth measuring precision, a numerical value within the usable bandwidth measuring range is used as detecting speed for sending a detection data packet, sending information is recorded; the detection data packet is received and receiving information is recorded; the sending information and receiving information of the detection data packet are obtained; according to the sending information and receiving information, whether the detecting speed is greater than the usable bandwidth is judged; if the detecting speed is greater than the usable bandwidth, the upper limit of the usable bandwidth measuring range is updated; if the detecting speed is less than or equal to the usable bandwidth, the lower limit of the usable bandwidth measuring range is updated till the usable bandwidth measuring range is less than or equal to the usable bandwidth measuring precision, then the numerical number within the usable bandwidth measuring range is used as the usable bandwidth. At the same time, the invention discloses a usable bandwidth measuring system and a device. The method, the system and the device can greatly improve the measuring speed of the usable bandwidth.

Method for connecting wireless signal dead zone to achieve meter reading

The invention provides a method for connecting a wireless signal dead zone node to achieve meter reading. A micro power wireless communication node in which communication fails in a wireless signal dead zone is replaced with a double-module communication module which has an electrical line carrier communication unit and a micro power wireless communication unit, after the double-module communication module receives data, a communication channel is selected for sending the data according to different conditions, and if the data is passively returned to be sent to the node, the data is returnedto a data frame through an original path according to the channel for receiving the data; if the data is sent to other nodes in a relaying mode or actively reported, a neighbor node table is utilizedto find out the successful communication frequencies of a target node and different communication modes of the double-module communication module to determine the sending channel, and which communication channel is adopted to send the data is determined by which communication channel has the largest successful communication frequency. When the node does not exist in the neighbor table or the successful communication frequencies of different communication channels are equal, a wireless communication channel is preferentially adopted to send the data, and therefore the sending and receiving success rate is increased.
