Filed: 2007-07-30
Abstract: A method and a system for providing a supplemental service to a caller or callee's phone in the middle of a call connection attempt are provided to offer various supplemental services according to a user's selection during a call connection attempt by receiving a command from a caller or a receiver in the middle of a call connection attempt and providing a supplemental service equivalent to the received command. If a caller requests a call connection to a callee's phone through his phone, the connection request is delivered to an MSC(Mobile Switching Center) through a base station(S510). The MSC asks an HLR or a VLR whether the caller or the callee is a subscriber of a specific supplemental service which can be provided during a call connection attempt(S520). In case it is confirmed that the caller or the callee is a subscriber of the specific supplemental service, the MSC switches the caller's phone to an IP(Intelligent Peripheral) through an SSP(Service Switching Point)(S530). Then, as the MSC transmits a call connection request signal to the callee's phone(S540), a ringing sound is outputted from the callee's phone(S550). At this moment, the IP transmits an announcement for the supplemental service to the caller's phone(S561,S562). If the caller pushes a specific key after listening to the announcement, the DTMF equivalent to the pushed key is transmitted to the IP through the MSC(S571-S573). The IP provides the supplemental service to the caller's phone through the MSC according to a command equivalent to the inputted key(S581,S582).
