Abstract: A network performance improvement method and an apparatus for user equipment. In the network performance improvement method, user equipment establishes a first PDN connection and transmits data of a first application program through the first PDN connection. Then, the user equipment starts a second application program and determines whether a current network status satisfies a quality of service requirement of the second application program. When determining that the current network status does not satisfy the quality of service requirement of the second application program, the user equipment starts to establish a second PDN connection, and transmits, after the second PDN connection is successfully established, at least a part of application data of the second application program through the second PDN connection.

Abstract: Embodiments of the present invention relate to the field of communications technologies and disclose a data processing method, apparatus, terminal, mobility management entity, and system, so as to reduce data transmission resources and avoid bringing an economic loss to a user. The method in the present invention includes: detecting a status of a data switch of a terminal, where the status includes a disabled state or an enabled state; and sending, by the terminal, a public data network PDN disconnection request to a mobility management entity MME after the status of the data switch is changed from the enabled state to the disabled state, where the PDN disconnection request carries information about a data bearer corresponding to a data domain access point name APN, and the PDN disconnection request is used to trigger the MME to delete the data bearer corresponding to the APN.
