Abstract: Methods and systems for facilitating access to a network (e.g., the Internet) are disclosed herein. A server with processor(s) and memory receives a request from a client device to download a network access configuration file, where the network access configuration file is configured to enable access to the Internet via a respective Internet access point. In accordance with the received request, the server identifies a first account in a social networking platform corresponding to a provider of the respective Internet access point. The server determines a relationship between the first account and a second account corresponding to a user of the client device in the social networking platform. In accordance with a first determination that the relationship satisfies one or more predetermined access criteria, the server provides the network access configuration file to the client device.

Abstract: A method is performed at a computer server for enabling voice communication between two terminals through IM service. Upon receiving a message from a remote computer, the message including an IM identifier of a callee terminal user and a mobile device identifier of the terminal, the computer system updates an entry for the callee terminal user in a database. Upon receiving a request from a caller terminal user at a caller terminal to start voice communication with the callee terminal user, the computer server identifies the entry that includes the IM identifier of the callee terminal user and sends a voice communication request to a service control point (SCP) in a switched telephone network. The SCP then returns an IP address and a port number of the callee terminal and launches a call request against the callee terminal. The computer server establishes a voice communication channel between the two terminals.
