SERVICE PROCESSING METHOD BASEBAND PROCESSING CHIP AND TERMINAL

摘要

Disclosed are a service processing method a baseband processing chip and a terminal. The service processing method comprises: in response to that a terminal needs to process a CS domain service identifying whether PS domain data received or sent in a PS domain service currently processed by the terminal is key data for maintaining the quality of the PS domain service; in response to that the received or sent PS domain data is non key data suspending processing of the PS domain service and processing the CS domain service. Embodiments of the present invention enable the terminal of Class B to process the CS domain service during the receiving and sending processes of the PS domain data.
