Abstract
A method and apparatus for video call connection in a dual standby mobile communication system are provided. A method for video call connection in a dual standby mobile communication terminal including a dual Subscriber Identity Module (SIM) card includes, when a paging signal requesting a video call is received from a network, identifying a system in which a first SIM card corresponding to the video call is camping, and, when the first SIM card is camping in a 2nd Generation (2G) system, identifying a system in which a second SIM card is camping, and, when the second SIM card is camping in a 3rd Generation (3G) system, requesting the network to forward the video call to the second SIM card.
Claims18
A method for video call connection in a mobile communication terminal comprising a dual Subscriber Identity Module (SIM) card, the method comprising:
- when a paging signal requesting a video call is received from a network, identifying a system in which a first SIM card corresponding to the video call is camping;
- when the first SIM card is camping in a 2nd Generation (2G) system, identifying a system in which a second SIM card is camping;
- and
- when the second SIM card is camping in a 3rd Generation (3G) system, requesting the network to forward the video call to the second SIM card.
A method for connecting a video call in a network, the method comprising:
- receiving a request for a video call connection for a specific phone number;
- transmitting a paging signal requesting the video call generation, to a receive Mobile Station (MS) corresponding to the specific phone number;
- receiving a request for forwarding the video call to a different phone number, from the receive MS;
- and
- transmitting the paging signal requesting the video call, to the MS corresponding to the different phone number.
An apparatus for video call connection in a mobile communication terminal comprising a dual Subscriber Identity Module (SIM) card, the apparatus comprising:
- a communication module for receiving a paging signal requesting a video call, from a network;
- and
- a controller for, when a first SIM card corresponding to the video call is camping in a 2nd Generation (2G) system and a second SIM card is camping in a 3rd Generation (3G) system, requesting the network to forward the video call to the second SIM card.
A network apparatus for connecting a video call of a Mobile Station (MS),
- wherein, when there is a request for a video call connection for a specific phone number, the apparatus transmits a paging signal requesting the video call to a receive MS corresponding to the specific phone number, and
- when there is a request for forwarding the video call to a different phone number from the receive MS, the apparatus transmits the paging signal requesting the video call to the MS corresponding to the different phone number.
A wireless communication method, comprising:
- receiving a signal requesting an incoming communication requiring a first wireless communication system;
- determining whether one of at least two SIM cards installed in a mobile terminal to which the communication is directed is camping in the first wireless communication system;
- when none of the SIM cards installed in the mobile terminal is camping the first wireless communication system, informing a user that the communication cannot be completed;
- and
- when at least one of the SIM cards installed in the mobile terminal is camping in the first wireless communication system, requesting a forwarding of the communication to one of the SIM cards camping in the first wireless communication system.
A mobile terminal, comprising:
- a master Subscriber Identity Module (SIM) card;
- a slave SIM card;
- a communication module for transmitting and receiving signals with respect to the master SIM card and the slave SIM card;
- and
- a controller for, when the communication module receives a request for a communication that requires a first wireless communication system, determining whether the master SIM card and/or the slave SIM card are camping in the first wireless communication system, and controlling the communication module based on the result of the determination,
- wherein, when the controller determines that the master SIM card is camping in the first wireless communication system, the controller controls the communication module to receive the communication via the master SIM card, and when the controller determines that the slave SIM card is camping in the first wireless communication system and the master SIM card is not camping in the first wireless communication system, the controller controls the communication module to transmit a forwarding request to forward the communication to the slave SIM card.
