Short message service ability updating method, device and apparatus

Abstract

Disclosed in the present application are a short message service (SMS) ability updating method, device and apparatus. The method includes a mobility management function receives a triggering condition of an SMS function/a user data management function, and/or, the mobility management function determines that SMS over NAS ability update needs to be triggered, the mobility management function updates the SMS over NAS ability of a UE. By using the present application, when a mobility management function receives a triggering condition of an SMS function a user data management function, and/or, the mobility management function determines that SMS over NAS ability update needs to be triggered, the mobility management function updates the SMS over NAS ability of the UE. The SMS over NAS ability update can be triggered by means of a network side, preventing the UE from making an erroneous SMS transmission attempt.

         10 . The method of  claim 9 , wherein the indication of SMS over NAS carried in the short message sending procedure is carried in a response returned by a short message function; or is determined and returned directly by the mobility management function to the UE. 
     
     
         11 . The method of  claim 1 , wherein the mobility management function determines that the SMS capability update is triggered when one or a combination of following conditions occurs:
 a change in operator configuration causes a network to trigger a change in the SMS over NAS capability;   subscription data obtained from the user data management function changes;   policy information of the user changes;   a change in relevant information is obtained through the short message function; and   the UE performs currently a deregistration procedure of which an access type is non-3GPP.   
     
     
         12 . A method for updating short message capability, comprising:
 receiving, by a User Equipment, UE, SMS over NAS capability update triggered by a mobility management function, wherein the SMS over NAS capability update is triggered by the mobility management function when receiving a triggering condition of a short message function or user data management function and/or determining that the SMS over NAS capability update is triggered; and   updating, by the UE, SMS over NAS capability of the UE according to a requirement of the mobility management function.   
     
     
         13 . The method of  claim 12 , wherein the updating SMS over NAS capability of the UE according to the requirement of the mobility management function comprises one or a combination of:
 triggering, through a configuration update procedure, the UE to initiate a registration update procedure to update the SMS over NAS capability;   updating the SMS over NAS capability of the UE through a configuration update procedure; and   updating the SMS over NAS capability of the UE in a corresponding procedure.   
     
     
         14 . The method of  claim 13 , wherein the triggering, through the configuration update procedure, the UE to initiate the registration update procedure to update the SMS over NAS capability comprises:
