Abstract:
Disclosed are a method and system for querying for a call transfer state. The method comprises: entering a call transfer query interface and querying for a call transfer state; determining whether call transfer information of an SIM card is stored in the SIM card or a mobile terminal where the SIM card is located; if the call transfer information of the SIM card is stored in the SIM card or the mobile terminal, reading the call transfer information of the SIM card stored in the SIM card or the mobile terminal; and if the call transfer information of the SIM card is not stored in the SIM card or the mobile terminal, delivering a call transfer query instruction to a network side, and storing the query result in the SIM card or the mobile terminal, and returning the query result to a call transfer application of the mobile terminal. When call transfer states are queried, local query is carried out first, and therefore, the situation of network query required by call transfer query each time is avoided, and the problem of an excessively long waiting time caused by signal jump in call transfer query each time is resolved.
