Abstract: Embodiments of the present invention provide an access point handover method and an apparatus. The method includes: sensing, by a terminal, that a currently connected access point cannot satisfy a transmission condition. The method includes finding, by the terminal, that at least one access point satisfying the transmission condition exists in access points having names partially the same as that of the currently connected access point. The method includes establishing, by the terminal, a connection to one of the at least one access point satisfying the transmission condition.

Abstract: The present disclosure describes a positioning method. In one example method, a target network identifier associated with a mobile terminal is obtained. A determination is made on whether positioning information of a region associated with the obtained target network identifier is stored locally at the mobile terminal. In response to determining that the positioning information of the region is not stored locally at the mobile terminal, the positioning information of the region is downloaded from a server to the mobile terminal and stored at the mobile terminal. In response to receiving a positioning request, geographical location information corresponding to the obtained target network identifier is obtained by the mobile terminal and from the locally stored positioning information of the region stored at the mobile terminal.

Abstract: The present disclosure relates to a transmit power control method and apparatus applied to a mobile terminal. One example method includes monitoring whether the mobile terminal has accessed a wireless access point AP. When the mobile terminal has accessed the AP, a received signal strength indicator (RSSI) of a signal that is sent by the AP and received by the mobile terminal is detected. A data sending rate at which the mobile terminal sends data to the AP is detected, and a transmit power relationship table is searched for a preset transmit power corresponding to both the RSSI and the data sending rate. A current transmit power of the mobile terminal to the first target transmit power is adjusted such that the mobile terminal sends data to the AP according to the first target transmit power. This method can reduce an unwanted power loss of the mobile terminal.

Abstract: A transmit power determining method and apparatus are disclosed. The method includes: calculating, channel state information of a channel between the wireless access point device and a station device within a particular time range; comparing, by the wireless access point device, the channel state information with pre-obtained reference channel state information, and adjusting, according to a result of the comparison, a transmit power currently used by the wireless access point device; and sending, by the wireless access point device to the station device by using a transmit power after the adjustment, a message carrying data. During implementation of the present disclosure, a transmit power for sending data can be adjusted according to channel state information corresponding to a channel between a wireless access point device and a station device, thereby avoiding unnecessary power overheads and a waste of energy.

Abstract: A frequency band switching method for a terminal includes: in response to determining that the terminal and a first access point (AP) transmit information by using a first frequency band, detecting a value of a channel quality parameter group, in response to determining that the value of the channel quality parameter group meets a preset condition, sending a connection request to a second AP, the connection request including a request for establishing a connection between the terminal and the second AP by using a second frequency band, and in response to determining that a success message fed back by the second AP according to the connection request is received, establishing, by the terminal, the connection with the second AP by using the second frequency band, and then sending a disconnection instruction to the first AP to break a connection between the terminal and the first AP.

Abstract: A method includes identifying, by a wireless communications module included in a communications device and when a Wireless Fidelity (Wi-Fi) mode of the communications device is already enabled, whether service data to be sent exists currently.

Abstract: A method and an apparatus for setting a working mode of power amplifier (PA) blanking are disclosed, which resolve a problem that, in the prior art, when a Global System for Mobile Communications (GSM) is working, because a PA blanking function cannot be configured flexibly to an enabled state or a disabled state, quality of a Global Positioning System (GPS) receiving signal is degraded. When a GPS is running, it is detected, at a preset interval, whether a GSM service is running. When the GSM service is running, a current quantity of timeslots occupied by the GSM service and a current power control level used by the GSM service are acquired.
