Abstract:
The present invention discloses a method for processing USSD service. In this method, when an application server determines that a mobile terminal on a VoLTE network supports USSD operations over IMS, the application server sends an invite message to the mobile terminal, where the invite message includes an identifier of a USSD service; receives an invite response from the mobile terminal, where the invite response carries reply information entered by a subscriber and the identifier of the USSD service; generates, according to the reply information, a message that requests to execute the USSD service, where the message that requests to execute the USSD service carries the identifier of the USSD service; and sends, to a subscriber data server, the message that requests to execute the USSD service, so that the subscriber data server processes the USSD service.

Abstract:
Embodiments of the present invention provide a called recovery method, including: receiving, by a target mobile switching center MSC, a provide roaming number PRN message sent by a backup MSC corresponding to a faulty MSC, where the PRN message carries an instruction for initiating paging to a called terminal through a mobility management entity MME; and performing international mobile subscriber identity IMSI paging according to the instruction, so that an MME to which a called terminal is attached controls the called terminal to perform circuit switched fallback CSFB to complete a called connection. Correspondingly, the embodiments of the present invention further provide a mobile switching center and a called recovery system. This solves a problem that in an MSC pool architecture, called paging in a CS domain cannot be performed when a terminal corresponding to a faulty MSC is attached to an E-UTRAN, and improves paging reliability.
