A method for network access control, communication system, and related device are disclosed. The method for network access control includes: generating a corresponding data request primitive data structure and sending the data request primitive data structure to a MAC layer in response to an association request command from a terminal device using a network layer, wherein the data request primitive data structure comprises information about a short address and an extended address of the terminal device; generating a corresponding pending data structure and storing the pending data structure in a preset pending queue in response to the data request primitive data structure using the MAC layer, wherein the pending data structure comprises a corresponding association response command frame and the information about the short address and the extended address of the terminal device; and acquiring a corresponding association response command from the pending data structure found in the pending queue and sending the association response command to the terminal device in response to a polling command from the terminal device, based on the information about the short address and the extended address carried in the polling command, using the MAC layer. The technical solution of the present disclosure can improve the network access success rate and speed of a terminal device.

A hybrid electro-optic modulator is described. The modulator comprises an electro-optic layer configured to support a hybrid mode propagating in a first direction, a pair of electrodes spaced apart in a second direction perpendicular to the first direction, the electrodes being positioned on the same side of the electro-optic layer and between the propagation path of the hybrid mode, wherein each electrode has a cross-sectional shape in a plane defined by the second direction and a third direction perpendicular to the first and second directions, the cross-sectional shape including a lower region joined to an elevated region via an angled region. The lower region is closer to the electro-optic layer than the elevated region in the third direction, the angled region extends towards the propagation path of the hybrid mode in the second direction, and the pair of elevated regions are closer than the pair of lower regions in the second direction.

A phase-locked loop circuit, a phase-locking method, and a frequency synthesizer are provided. The phase-locked loop circuit employs phase-rolling clock signal generator component to perform integer frequency division on multiple oscillation clock signals with uniformly varying phases to obtain multiple feedback clock signals with uniformly varying phases; and according to a preset clock cycle, select feedback clock signals with corresponding phase sequences from the multiple feedback clock signals with uniformly varying phases for concatenation, thereby generating the phase-rolling clock signal. This architecture enables fractional-N frequency division phase-locked loop operation. Compared with conventional fractional-N frequency division phase-locked loop implementations using sigma-delta modulator (SDM) circuits, the proposed solution reduces circuit area and power consumption while improving phase-locked loop performance.
