Abstract
A call hold method includes receiving a call hold request sent from a peer end; returning a 200 OK message to the peer end; receiving a user instruction for sending a call hold request to the peer end; determining whether an acknowledgement message based on the call hold request of the peer end is received from the peer end; and processing, based on an acknowledgement message determining result, the user instruction for sending a call hold request to the peer end. Accordingly, when a user has a call hold request, a mobile terminal first determines whether a procedure based on the call hold request of the peer end is completed at the peer end, and then determines to process the call hold request of the user, thereby preventing a call drop.
Claims20
A call hold method for a mobile terminal, comprising:
- receiving a first call hold request from a peer end;
- returning an OK message in response to the peer end;
- receiving a user instruction for sending a second call hold request to the peer end;
- determining whether an acknowledgement message based on the first call hold request of the peer end is received from the peer end;
- and
- processing, based on an acknowledgement message determining result, the user instruction for sending the second call hold request to the peer end by sending the second call hold request to the peer end after the acknowledgment message based on the first call hold request of the peer end is received from the peer end.
A mobile terminal, comprising:
- a memory comprising instructions;
- and
- a computer processor coupled to the memory and configured to execute the instructions to configure the mobile terminal to:
- receive a first call hold request sent from a peer end;
- return an OK message to the peer end;
- receive a user instruction for sending a second call hold request to the peer end;
- determine whether an acknowledgement message based on the first call hold request of the peer end is received from the peer end;
- and
- process, based on an acknowledgement message determining result, the user instruction for sending the second call hold request to the peer end by sending the second call hold request to the peer end after the acknowledgement message based on the first call hold request of the peer end is received from the peer end.
A mobile terminal, comprising:
- a receiver configured to receive a first call hold request sent from a peer end;
- a transmitter configured to return an OK message to the peer end;
- a second receiver configured to receive a user instruction for sending the second call hold request to the peer end;
- and
- a processor configured to:
- determine whether an acknowledgement message based on the first call hold request of the peer end is received from the peer end;
- and
- process, based on an acknowledgement message determining result, the user instruction for sending the second call hold request to the peer end by sending the second call hold request to the peer end with a second transmitter after the acknowledgement message based on the first call hold request of the peer end is received from the peer end.
