A method for accessing an old network through a temporary ID of an evolved network includes these steps: a User Equipment (UE) adds Mobility Management Entity (MME) information for uniquely identifying an MME accessed by the UE on an evolved network to an access message sent to an old network when the UE accesses the old network through a temporary ID of the evolved network; and the old network selects a corresponding Serving GPRS Support Node (SGSN) for the UE according to the access message. After the MME information for uniquely identifying an MME is added to the access message sent to the old network, the old network can determine and find the MME that is accessed by the UE in the evolved network without changing a Radio Network Controller (RNC) and an SGSN on the old network. In addition, with the method for accessing the evolved network through a temporary ID of the old network, a combined SGSN/MME can be accessed to prevent unnecessary node relocation. |
