First Claim
Patent Images
1. A method of handling a Push-To (PT) session service in a wireless communication system supporting a session initiation protocol (SIP), the method comprising:
- receiving, from a terminal, a SIP invite message to initiate a session for at least one of many target terminals;
checking whether a PT service setting has been received from each of the target terminals;
checking PT box access condition information associated with one or more particular target terminals, if the PT service setting has not been received from those one or more particular target terminals; and
determining whether to forward the SIP invite message to the PT box or to transmit a failure message to the terminal based on the checking of the PT box access condition information.
