Abstract: A single-beam three-degree-of-freedom homodyne laser interferometer based on an array detector. A single-frequency laser beam is input to a Michelson interference structure, the measurement beam and the reference beam perform non-coaxial interference and form a single-beam homodyne interference signal by setting the angle of a reference plane mirror, the array detector is selected to effectively receive the single-beam homodyne interference signal, and finally, three-degree-of-freedom signal linear decoupling on the single-beam homodyne interference signal is achieved through a three-degree-of-freedom decoupling method based on Lissajous ellipse fitting.

Abstract: A trunking user based message transmission method and device. The method comprises: receiving a request message from a user equipment (UE) by the wireless access device, and allocating a connection resource for the UE by the wireless access device, wherein the request message carries information indicating whether the UE is a trunking user; when the UE is a trunking user, and if the UE does not receive or send data within a preset period, triggering the UE to enter a CELL_PCH state by the wireless access device; and when the UE is not a trunking user, and if the UE does not receive or send data within a preset period, releasing the connection resource of the UE by the wireless access device.

Abstract: Disclosed are an access method for a WiFi access point, a WiFi access point and a WiFi system, which relate to communications technology. The present application adds to a WiFi system the RAN and PSCN of a 3G network, and adds a 3G module to an AP, so that the AP can serve as a 3G terminal to access the 3G network, thereby connecting the AP and an AC/BRAS through the RAN and PSCN. Because the 3G network has broader coverage, implementing access point access through the 3G network reduces the complexity of an AP accessing the AC/BRAS.

Abstract: A cluster user based message transmission method and device. The method comprises: receiving a request message from a user equipment (UE) by the wireless access device, and allocating a connection resource for the UE by the wireless access device, wherein the request message carries information indicating whether the UE is a cluster user; when the UE is a cluster user, and if the UE does not receive or send data within a preset period, triggering the UE to enter a CELL_PCH state by the wireless access device; and when the UE is not a cluster user, and if the UE does not receive or send data within a preset period, releasing the connection resource of the UE by the wireless access device.
