Abstract: A wireless local area network (WLAN) access method includes sending, by a terminal, a request for querying an available wireless access point to a server. The method further includes sending, by the server according to the query request, obtained information about the available wireless access point. The method further includes receiving, by the terminal, wireless access point information returned by the server, and determining a specific wireless access point from the received wireless access point information. The method further includes sending, by the terminal, an authentication information request of the specific wireless access point to the server. The method further includes when receiving the request, sending, by the server, authentication information corresponding to the specific wireless access point to the terminal, where the authentication information is used to connect the terminal to the specific wireless access point.

Abstract: Embodiments of the present disclosure provide a recharging method for a virtual identity module, and a device. A first recharge request that is sent by user equipment and carries user account information and recharge information is received; a to-be-recharged virtual identity module and a recharge amount are determined according to the recharge information; a second recharge request is sent to an operations support system of the to-be-recharged virtual identity module, where the second recharge request carries the recharge amount and the user account information, so that the operations support system of the to-be-recharged virtual identity module deducts the recharge amount from an account corresponding to the user account information, and recharges the to-be-recharged virtual identity module. Recharging manners are diversified, and a recharging process is more flexible and convenient.

Abstract: The present invention discloses an application distribution method, a terminal, and a server. The method includes: sending, by a first terminal, a distribution request to an application distribution server; when the distribution request satisfies a preset criterion of the application distribution server, receiving at least one propagation code sent by the application distribution server; and sending the propagation code to a second terminal, so that the second terminal completes registration, running, and tracking of an application according to the propagation code. The present invention can be applied to an intelligent terminal for acquiring and distributing an application, however, the present invention is not limited thereto.

Abstract: Embodiments of the present invention provide methods for sending and receiving user data and terminal devices, to resolve a problem that user data cannot be transferred together with SIM card data. The method includes: receiving, by a first terminal, an instruction for transferring a virtual subscriber identity module SIM card of the first terminal to a second terminal; acquiring, by the first terminal according to the instruction, user data associated with the virtual SIM card; and sending, by the first terminal, the user data to a server, or sending, by the first terminal, the user data to the second terminal.

Abstract: A distribution method is disclosed. A distribution device receives based on a near field communication protocol, a virtual user identification data acquiring request sent by a terminal device. The virtual user identification data acquiring request carries service selection information of virtual user identification data that needs to be acquired. According to the service selection information, subscription relationship data of virtual user identification data matching the service selection information is determined. The distribution device sends the subscription relationship data to the terminal device based on the near field communication protocol.
