<P>PROBLEM TO BE SOLVED: To appropriately provide a PS (Packet Switch) service and a CS (Circuit Switch) service, without relying on a "UE (User Equipment) mode of operation" setting in each UE. <P>SOLUTION: The mobile communication method includes: a step in which the UE transmits an "Attach Request" to E-UTRAN (Evolved-Universal Terrestrial Radio Access Network); a step in which an MME transmits the "Attach Reject", where "#15" is set to the UE as a "Cause value", when the MME receives the "Attach Request", receives a notification indicating that the UE cannot be connected to a desired PDN (packet Data Network) from an authentication server 1, and determines that the UE can use CS communication; and a step in which the UE transmits the "Attach Request" to a UTRAN (Universal Terrestrial Radio Access Network)/GERAN (GSM Edge Radio Access Network) when the UE receives the "Attach Reject" where "#15" is set as the "Cause value." <P>COPYRIGHT: (C)2012,JPO&INPIT |
