Treatment method and system of extension telephone traffic in virtual switchboard as well as virtual switchboard server

The invention discloses a treatment method and system of extension telephone traffic in a virtual switchboard as well as a virtual switchboard server. The virtual switchboard server connected with an intelligent network comprises a user management unit, a calling control unit and a traffic control unit; when an incoming call calls a first extension telephone in a group, the traffic control unit controls the calling control unit to get through a talk channel between the incoming call and the first extension telephone; and when the incoming call needs to be forwarded to a second extension telephone in the group, the traffic control unit receives a forwarding command of the first extension telephone or the second extension telephone, acquires the information of the second extension telephone in the forwarding command through the user management unit and controls the calling control unit to forward the incoming call from the first extension telephone to the second extension telephone so as to realize the talk between the incoming call and the second extension telephone. The invention is more convenient and timely for the extension telephones in the group to forward and pick up without regional limitation.

Self-adaptive resonant frequency method and self-adaptive resonant frequency device

The invention discloses a self-adaptive resonant frequency method and a self-adaptive resonant frequency device. The self-adaptive resonant frequency method comprises the following steps: when a terminal receives a card search request from an upper computer, the terminal executes the following steps: step 1, the terminal carries out card search according to a yield value and obtains a card search result; step 2, the terminal judges whether card search is successful according to the card search result, if so, the terminal returns an operation result to the upper computer, if not, the terminal executes step 3; step 3, the terminal updates an error code according to the card search result; step 4, the terminal adjusts the yield value according to the error code; and step 5, the terminal judges whether the adjusted yield value is in a first default range, if so, the terminal executes the step 1, and if not, the terminal returns card search failure information to the upper computer to finish. By utilizing the self-adaptive resonant frequency method, the yield value of the smart card signal received by the terminal is automatically adjusted according to error type generated in card search process, and the communication efficiency of the terminal and a smart card is improved.
