摘要

A method, system and device for suspending the service and a method, system and device for resuming the service are provided. Thereinto, the method for suspending the service includes that: when the user equipment residing in the packet domain needs initiate the circuit domain service, the core network device of the packet domain keeps the packet domain network resource of the user equipment according to the received indication; when the user equipment is processing the service currently, the downlink service data transmitted to the user equipment is buffered and/or the transmission of the uplink data is terminated, and transforming to the circuit domain communication network to process the circuit domain service.
