Embodiments of this application provide a CSFB method and apparatus. The method includes: learning, by a source access network device, that CSFB needs to be performed on a terminal, where performing the CSFB on the terminal includes moving the terminal from a first standard network to a second standard network; determining, by the source access network device before completing moving of the terminal from the first standard network to the second standard network, that a serving cell handover needs to be performed on the terminal in the first standard network; and performing, by the source access network device, the serving cell handover on the terminal, where the source access network device sends CSFB information to a target access network device in a process of the serving cell handover.

A communication device of the disclosure includes a phase synchronizer, a modulator, and a controller. The phase synchronizer generates a second signal on a basis of a first signal received from a communication partner by selectively performing one of a closed loop operation and an open loop operation. The modulator is able to modulate the first signal on a basis of the second signal. The controller controls operations of the phase synchronizer and the modulator.

A method of operating a smart lighting system comprising a first mobile device, a lighting control device and first through nth (n being a positive integer) lighting devices, includes establishing, by the first mobile device, a first wireless connection with the lighting control device; performing, by the lighting control device, a first time synchronization with the first mobile device; providing, by the first mobile device, the lighting control device with a scheduling information representing operation of each of the first through nth lighting devices according to lapse of time; and controlling, by the lighting control device, operation of each of the first through nth lighting devices based on a current time and the scheduling information, wherein the current time is determined based on the time synchronization.

Spectrum access allocation processes and systems are described in which multiple tiers of predetermined transmission powers are enforced, and where access is established by transmission at or below the lowest predetermined transmission power. The allocation processes include provisioning a wireless interface between a spectrum access system and a user equipment that is not registered with the spectrum access system. The wireless interface permits data transfer at or below a first predetermined power setting. A request to register the user equipment with the spectrum access system is transmitted to a spectrum access server. The spectrum access server receives a message from the spectrum access server indicating that the user equipment has been registered with the spectrum access system. The user equipment is controlled to transmit data at a second predetermined power setting that is greater than the first predetermined power setting.

In an embodiment, a bridge circuit is configured for connecting a desk phone (e.g., a VoIP phone) to a mobile device (e.g., a smart phone), while allowing the existing desk-phone VoIP/PSTN system (e.g., a PBX system) to be eliminated with significant savings in reduced telecommunication-infrastructure costs. The bridge circuit can be powered through traditional wall power, and can include a CAT 5 cable port with Power Over Ethernet (PoE), a PSTN port such as an RJ11 port, a set of electronics that provide wireless connectivity to the mobile device, a control circuit, and a set of software instructions for programming the desk phone to communicate with the bridge circuit and for providing other features such as conference calling, putting a call on hold, and transferring contact information from the mobile device to the desk phone or vice-versa.

An in-place imaging device, including: a housing and a support stand, the housing including: a camera; a wireless communication module; a touch sensitive screen configured for displaying content and receiving input; and a processing unit; wherein the imaging device is adapted to capture footage with the camera and transmitting the footage via the wireless communication module to a network access point. The footage is transmitted to a media server via a communications network to which the network access point is connected.

Various embodiments comprise systems, methods, and apparatus for allocating resources in a 5G network comprising Citizens Broadband Radio Service Device (CBSD) nodes configured for communicating via granted spectrum with customer premises equipment (CPE) supporting wireless access points (WAPs) and the like, wherein an initial small bandwidth part (BWP) is assigned to each CPE, a BWP update process provides to a policy control function a list of devices/capabilities consuming CPE bandwidth so that the PCF may calculate a new bandwidth requirement for the CPE, the new requirement being used by the CPE to generate a CPE UE capability information message for the CBSD node, the CBSD node assigning an appropriately sized BWP for the CPE.

In one embodiment of the present invention, a portable computing device for wireless communications comprises a first network interface for communicating with a public wireless wide area network (WWAN), a second network interface for communicating with a private wireless local area network (WLAN), and a processor executing under control of software instructions, the software instructions defining a gateway protocol, the gateway protocol establishing the portable computing device as an access point within the private WLAN after the wireless presence on the public WWAN is established.

Various techniques and systems are provided for determining a location of a target wireless device. Specifically, various techniques and systems are provided for determining a location of a wireless device using timestamps assigned to communications transmitted between the wireless device and one or more other wireless devices on a same WiFi channel as the wireless device. Implementations describe devices, computer-program products, and methods including transmitting a beacon frame by a network device on a channel of a radio frequency band, receiving a first frame that corresponds to the client device, assigning a first timestamp to the first frame, transmitting a second frame in response to the client device communication, assigning a second timestamp to the second frame, determining a time difference between the first timestamp and the second timestamp, receiving an alternative time difference corresponding to an alternative network device on the channel, and determining a location of the client device using the time difference and the alternative time difference.

Methods, systems, and computer readable media may be operable to facilitate the initiation of a wireless setup between a station and an access point upon the station receiving a predetermined input from a user. The status of a wireless connection between the station and an access point may be displayed to a user through one or more display interfaces or light indicators associated with the station. The methods, systems, and computer readable media described herein allow a user to initiate and monitor a wireless setup between a station and an access point without having to connect a display device to the station.
