Abstract: The present disclosure provides a discovery method, a device and a system for an application layer traffic optimization server, which relate to communication field, so as to reduce the cross-domain traffic and meet the network optimization demand of a network ISP as an internet access point. The method for an application layer traffic optimization server, related to a terminal side, comprising: obtaining a domain name of a proxy server for a terminal data layer to access internet; obtaining, according to a query name constructed using the domain name of the proxy server, an address of an application layer traffic optimization ALTO server related to the proxy server from a domain name server DNS; and communicating with the ALTO server according to the address of the ALTO server. Embodiments of the present disclosure are mainly applied to the communication between the terminal and the ALTO server.

Abstract: Embodiments of the present invention disclose a resource control method and apparatus. A client sends an authorization request message to a content provider. The content provider sends an authorization response message to the client according to a user identifier carried in the authorization request message, where the authorization response message carries an authorized access token. The client sends a content request message to a storage server corresponding to the content provider, where the content request message carries an identifier of content requested by the client and the authorized access token. The client receives the content sent by the storage server according to the authorized access token. The present invention is applied to the field of network resource management.

Abstract: A wireless network handover method and apparatus are provided, relating to the communications field, and capable of resolving a problem of a service packet loss during a handover of a terminal. The method includes: obtaining, by a handover device, a distance between a terminal and a current access point, to determine a change trend of the distance between the terminal and the current access point; and if the handover device determines, based on a correspondence between the change trend and a neighboring access point of the current access point, a target access point to which the terminal is to be handed over, handing over, by the handover device, the terminal from the current access point to the target access point. Embodiments of the present invention are applied to a scenario in which a terminal is handed over and roams between Wi-Fi networks on a highway.
