 As shown in the preceding figure, the telephony core service consists of the following:
 
 -   SimManager: provides services including SIM card initialization, file read/write, loading status notification, and single-SIM/dual-SIM control. These services implement functions such as SIM card status query, SIM card management, SIM card control, STK, contact storage, and SMS storage.
--   NetworkSearchManager: provides services including network registration and network status acquisition. These services offer functions such as network registration, network mode query, radio service status query, radio service management, signal strength query, cell management, registration status management, and time and time zone setting.
+-   NetworkSearchManager: provides services including network registration and network status acquisition. These services offer functions such as network registration, network mode query, IMS network status reporting, radio service status query, radio service management, signal strength query, cell management, registration status management, and time and time zone setting.
 -   TelRilManager: provides the proactive callback service and query result callback service.
