<p>The disclosure discloses a method and a system for processing prior services, the method includes that: an eNB and/or an MME carries a service priority indication in a message sent to a UE in mobile terminating call procedures for CSFB; and the UE sends a GERAN or a UTRAN a priority indication corresponding to a service when the GERAN or the UTRAN initiates the service. With the disclosure, a source network E-UTRAN can take full advantage of an existing message to carry service information to notify a UE, the UE forwards the information to a target network GERAN/UTRAN, so as to avoid failure of a high priority service in the target network.</p> |
