Implementation method for improving service call completion ratio and radio network controller

An implementation method for improving a service call completion ratio, comprising:

• a serving radio network controller sending a radio bearer establishment message to a user equipment;
• the serving radio network controller judging that a radio bearer response message from the user equipment is not received within a first predetermined period, the serving radio network controller triggering the user equipment to report a cell update message;
• the serving radio network controller sending a radio link deactivation message or a radio link deletion message to a drift radio network controller;
• the serving radio network controller receiving the cell update message from the user equipment and determining a configuration status of the user equipment according to information carried in the cell update message and/or time when receiving the cell update message;
• and
• the serving radio network controller performing call reestablishment processing according to the configuration status of the user equipment.

A radio network controller, characterized by comprising:

• a sending module, configured to send a radio bearer establishment message to a user equipment;
• a first judging module, configured to judge whether a radio bearer response message from the user equipment is not received within a first predetermined period;
• a triggering module, configured to trigger, when a result of judgment of the first judging module is YES, the user equipment to report a cell update message;
• a receiving module, configured to receive the cell update message from the user equipment;
• and
• a second judging module, configured to determine a configuration status of the user equipment according to information carried in the cell update message and/or time when receiving the cell update message;
• a reestablishment processing module, configured to perform call reestablishment processing according to the configuration status of the user equipment determined by the second judging module;
• and
• a first hardware processor, configured to execute the sending module, the first judging module, the triggering module, the receiving module, the second judging module and the reestablishment processing module.

A radio network controller, comprising:

• a first sending module, configured to send a radio bearer establishment message to a user equipment;

• a second sending module, configured to send a radio link deactivation message or a radio link deletion message to a drift radio network controller;
• a receiving module, configured to receive the cell update message from the user equipment;
• a second judging module, configured to determine a configuration status of the user equipment according to information carried in the cell update message and/or time when receiving the cell update message;
• and
• a reestablishment processing module, configured to perform call reestablishment processing according to the configuration status of the user equipment determined by the second judging module;
• a second hardware processor, configured to execute the first sending module, the first judging module, the triggering module, the second sending module, the receiving module, the second judging module and the reestablishment processing module.
