The present invention discloses a data routing method, including: receiving, by an HSS, a route distinguisher of an MME serving UE sent by the MME; determining, by the HSS according to the route distinguisher of the MME, an information transmission manner supported by the MME, where the route distinguisher of the MME is in a one-to-one correspondence with the information transmission manner supported by the MME; receiving, by the HSS, a query message sent by an MTC-IWF, where the query message carries a user equipment UE identifier and an information transmission manner that needs to be used; determining, by the HSS according to the information transmission manner supported by the MME, the UE identifier, and the information transmission manner that needs to be used, that the MME serving the UE supports the information transmission manner that needs to be used; and sending, by the HSS, a route distinguisher of the MME that corresponds to the information transmission manner that needs to be used to the MTC-IWF, so that the MTC-IWF performs routing according to the route distinguisher. Therefore, a most effective transmission path is selected for information transmission, thereby improving service experience of a user. |
