Abstract: The present invention provides a method for customizing application services of a data card. The system comprises a data card and an over-the-air server. The method comprises: the data card sending an application service customization request to the over-the-air server when an application service is required to be customized; and the over-the-air server receiving the application service customization request, and then returning a configuration command corresponding to configuration information to the data card if it is determined that an operation of the data card to request customization of the application service is valid according to the stored and managed configuration information of all application services supported by the data card.

Abstract: A system for implementing an access point name setting is disclosed, including: a mobile terminal and an access point name server, wherein, the mobile terminal is configured to: when access point name information is required to be set, send an access point name inquiry request to the access point name server; the access point name server is configured to: after receiving the access point name inquiry request of the mobile terminal, carry the access point name information corresponding to the mobile terminal in an access point name inquiry response to return to the mobile terminal. A mobile terminal and method for implementing the access point name setting are also disclosed. The mobile terminal is enabled to perform automatic setting for an APN conveniently, bringing great convenience to a mobile terminal user.

Abstract: A communication device based on a USB interface and a method for implementing service configuration are provided. The method is used for the communication device based on the USB interface, comprising: said communication device based on the USB interface reporting a device descriptor to a host, thus making said host complete loading of a host driver; said communication device based on the USB interface receiving a control instruction sent from the host side through the USB interface; and said communication device based on the USB interface configuring service attribute information according to said control instruction, so as to enable said service attribute information to indicate service attributes of said communication device based on the USB interface. The USB control information controls the service attribute information such that said device can implement support to service differentiation aiming at different operating systems.
