DATA TRANSMISSION METHOD, MOBILITY MANAGEMENT ENTITY, AND MOBILE TERMINAL

摘要

Embodiments of the present invention disclose a data transmission method, a mobility management entity, and a mobile terminal. The method includes: receiving, by a mobility management entity, a small data transmission parameter that is sent by a home subscriber server HSS or a user equipment, where the small data transmission parameter includes an indication of whether the user equipment supports small data transmission; determining, by the mobility management entity, a small data transmission policy according to the small data transmission parameter; sending, by the mobility management entity, the determined small data transmission policy to the user equipment; and performing, by the mobility management entity, the small data transmission with the user equipment according to the small data transmission policy. The present invention proposes a relatively complete small data transmission solution, thereby implementing effective transmission of small data.

主权项

1. A mobility management entity, comprising:
a receiver, configured to receive a small data transmission parameter from a home subscriber server (HSS) or a user equipment, wherein the small data transmission parameter comprises an indication of whether the user equipment supports small data transmission; a processor, configured to determine a small data transmission policy according to the small data transmission parameter; a transmitter, configured to send the small data transmission policy to the user equipment; and wherein the processor is further configured to perform, via at least one of the receiver and the transmitter, the small data transmission with the user equipment according to the small data transmission policy.
