Abstract: Embodiments of this application relate to a cell access method and apparatus, and a device, and the method includes: obtaining a movement speed of a terminal; determining a signal strength offset value based on the movement speed; obtaining signal strength of a serving cell and signal strength of at least one neighboring cell, where the serving cell is a cell on which the terminal currently camps, and the neighboring cell is a cell in which the terminal can receive a signal; determining whether a sum of signal strength of a first neighboring cell in the at least one neighboring cell and the offset value is greater than or equal to a preset threshold; and if the sum of the signal strength of the first neighboring cell and the offset value is greater than or equal to the preset threshold, accessing, by the terminal, the first neighboring cell. The cell access method and apparatus and the device provided in the embodiments of this application can resolve a problem of frequent network disconnection of the terminal in a high-speed movement process, so that a call completion rate of the terminal can be improved.

Abstract: This application provides a service connection establishment method, a Bluetooth master device, and a chip. After scanning a device combination including at least two Bluetooth slave devices, the Bluetooth master device, if required to establish a service connection with each of Bluetooth slave devices in the device combination, needs to do as follows: in a pairing phase, the Bluetooth master device automatically pairs with another Bluetooth slave device in the device combination after completing pairing with one Bluetooth slave device in the device combination; in a service connection establishment phase, similarly, the Bluetooth master device automatically establishes a service connection with another Bluetooth slave device in the device combination after establishing a service connection with one Bluetooth slave device in the device combination. This is a simple process, and a speed of service connection establishment is high.

Abstract: The present disclosure discloses a method for determining transmit power and a user equipment, which relates to the field of information technologies, and can improve a success rate of establishing a connection between the user equipment and a base station. The method includes: determining, according to a preconfigured rule, a transmit power used for sending a random access message; and, sending the random access message to a base station by using the determined transmit power. The present disclosure is applicable to establishment of the connection between the user equipment and the base station.
