Abstract

The present invention provides a method and device for sending a short message, comprising: after the mobile management entity MME determines that the user equipment is reachable, it sends a keep-alive notification to the base station connected to the user equipment, or notifies the short message center to send the short message immediately without delay, and After receiving the short message sent by the mobile switching center, forward the short message to the base station for delivery. Thus, the successful sending of the short message is ensured, and the reliability of the system is improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for sending short messages. Background technique [0002] A short message (also called a short message, short message) is a function commonly used in a mobile communication system. In the 4th generation (4G) mobile communication system, the short message is sent from the short message center (SMC) to the mobile switching center (MSC), and the MSC forwards the short message to the mobile management entity MME (mobile management entity) , the MME then sends the short message to the base station at the current location of the user equipment, and finally sends it to the user equipment UE (user equipment). The user equipment can be a mobile phone, or other terminals that can receive short messages. [0003] In some cases, such as when the mobile phone is turned off, the user's device is unreachable, and the SMS cannot be sent to the user's device. When the user's equip...
