Provided is a flux regulation method for use in a power converter, wherein the method is carried out by a flux bias controller. The flux bias controller includes a current detector which is configured to detect the primary current of the transformer of the power converter in a predetermined switching cycle, a DC bias processor which is configured to obtain the duty ratio control signal according to the sampled primary current outputted from the current detector for a switching cycle later than the predetermined switching cycle, and a PWM controller which is configured to generate driving signals to control the on/off operations of the switching circuit of the power converter according to the duty ratio control signal, thereby suppressing the DC bias of the transformer by regulating the duty ratio of the switch circuit.

A method and device for monitoring paging signals are provided. A method of DRX cycle extension for a mobile terminal in an IDLE mode is provided. The method is used to extend the current DRX cycle. A longer paging cycle is designed by extending a UE-specific paging cycle or introducing a new coefficient in system information. A method for extending the SFN is proposed in the invention. A boundary and a serial number of the SFN in the longer wrap around are indicated by the SI. To avoid a situation in which the high paging load occurs in certain paging frames or subframes, the UE_ID is extended in the invention. The proposed mechanism can flexibly adjust the paging cycle and the SFN extension to meet the actual requirements. The long DRX cycle can save a lot of power consumption of the mobile terminals in the IDLE mode.

This invention proposes efficient data transmission methods in the mobile cellular network. A specific resource pool is divided into several resource groups to indicate the size level of the data available for transmission. The base station allocates a proper UL grant to the terminal. Based on the allocated UL grant, the terminal compares the granted Transport Block (TB) size with the size of data available for transmission. If the UL grant is large enough, the terminal transmits the data available for transmission in the allocated UL resource, otherwise, re-attempts the random access procedure. In another example, the terminal transmits a BSR message and as much of the data as is available for transmission. The base station may grant additional UL resources if there is remaining data to be transmitted. A timer is used for the terminal to decide whether waiting for the additional UL grant from the base station.

A method and system for service protection based on the Dual Node Interconnection (DNI) protection structure in the transport network are provided. When creating a DNI protection group, a plurality of services are configured in one direction, wherein one is a working service, and the others are protection services; the multiple services have the same add node and drop node, but not exactly the same passed interconnection nodes; on each interconnection node of the add ring, two services in the DNI protection group through the local node to the drop ring are adapted as two services in a 1+1 protection group; on the drop node, services in the DNI protection group are adapted as two services in a 1+1 protection group transmitted from two directions of the drop ring; when a fault occurs, said interconnection node and drop node execute switching according to the 1+1 protection protocol.
