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.
