- the SIP REFER procedure is used to switch the session establishment entity and the media exchange entity from the transfer source terminal 100 to the transfer destination terminal. However, only the media exchange entity is used. May be switched to the transfer destination terminal. This can be realized, for example, when the transfer source terminal 100 executes a SIP re-INVITE procedure for the communication destination terminal 300 to change only the media reception destination to the transfer destination terminal. By performing such processing, a SIP session is established between the transfer source terminal 100 and the communication destination terminal 300, and only media exchange is performed between the transfer destination terminal and the communication destination terminal. Is possible.
- the transfer source terminal 100, the neighboring terminal 200, and the communication destination terminal 300 are connected via a plurality of networks, but all the terminals are the same.
- the terminal switching operation can be performed in the same way even when connected to the network.
- the user communication for switching the terminal is described as an example of a video conference, but the same processing is applied to other user communication such as voice call and data distribution. It is possible.
- a transfer destination candidate terminal is determined based on terminal information acquired by the transfer source terminal 100 searching for the neighboring terminal 200 using short-range radio.
- the difference from Embodiment 1 is that only the transfer destination candidate terminal is requested for connectivity information after terminal switching.
- FIG. 12 is a diagram showing a configuration of a transfer source terminal of the terminal switching system according to the second embodiment.
- the overall control unit 1206 includes a terminal information receiving unit 1206a and a transfer destination candidate terminal determining unit 1206b, which is different from the first embodiment.
- the terminal information receiving unit 1206a receives terminal information from the neighboring terminal 200.
- the transfer destination candidate terminal determination unit 1206b determines the current destination based on the terminal information of each neighboring terminal 200.
- the terminal that can determine that the existing communication can be continued is determined as the transfer destination candidate terminal.
- FIG. 13 is a diagram showing the configuration of neighboring terminals of the terminal switching system in the second embodiment.
- overall control unit 1306 is different from embodiment 1 in that terminal information transmission unit 1306a is provided.
- the terminal information transmission unit 1306a transmits a terminal information request notification to which the information acquired from the own terminal information 208 is added to the transfer source terminal 100.
- transfer source terminal 100 establishes a SIP session with communication destination terminal 300 in the same manner as in the first embodiment, and performs media exchange (step S201).
- the user power holding the transfer source terminal 100
- the short-range wireless transmission / reception unit 105 of the transfer source terminal 100 detects this and performs overall control. Section 1206 is notified (step S 202).
- the overall control unit 1206 Upon receiving the notification, the overall control unit 1206 sends a terminal information request for requesting terminal information related to the IP address, various capabilities, and functions to the detected neighboring terminal 200 via the short-range wireless transmission / reception unit 105. (Step S203).
- the terminal information transmission unit 1306a causes the short-range wireless transmission / reception unit 205 to Then, the terminal information request notification including the information acquired from the own terminal information 208 is transmitted to the transfer source terminal 100 (step S204).
- the usable codec is “MPEG 1, MPEG2”, the resolution is “1600 X 1200”, and the IP address is “202.xxx.xxx. xxx ”and! ⁇ ⁇ information is acquired from the own terminal information 208 and appended to the terminal information notification.
- terminal information reception section 1206a of transfer source terminal 100 receives terminal information notification from neighboring terminal 200 via short-range wireless transmission / reception section 105, it transmits the terminal information included in the terminal information notification to the vicinity. Stored in terminal information 110. Then, when the transfer source terminal 100 receives the terminal information notifications from all the neighboring terminals 200 or when the terminal information notification waiting time from the neighboring terminals 200 times out, the transfer destination candidate terminal of the transfer source terminal 100 is determined. Based on the terminal information of each neighboring terminal 200, unit 1206b determines a terminal that can determine that the current communication can be continued as a transfer destination candidate terminal (step S205).
- the transfer destination candidate terminal determination unit 1206b can also remove the transfer destination candidate terminal capability of the neighboring terminal 200 that cannot use the media and codec used in the current communication media exchange.
- the transfer destination candidate terminal determination unit 1206b determines whether the screen size is lower than a certain value or is connected to a pay network based on a switching policy set in advance by the user. It is also possible to remove it from the candidate terminal. Note that multiple transfer destination candidate terminals may be selected.
- transfer source terminal 100 performs the same processing as in steps S103 to S116 of the first embodiment, and switches the connectivity from the transfer destination candidate terminal.
- Information is acquired (step S206 to step S208), a transfer destination terminal is determined (step S209), and a session is transferred (step S210 to step S218).
- the session established between the transfer source terminal 100 and the communication destination terminal 300 is transferred to the transfer destination terminal determined by the transfer destination terminal determination unit, and the terminal is switched. . Thereafter, the neighboring terminal 200b, which is the transfer destination terminal, establishes a session with the communication destination terminal 300 and starts media exchange (step S219).
- the overall control unit 1206 of the transfer source terminal 100 may specify the terminal type and the necessary function in the terminal information request issued from the transfer source terminal 100 to the neighboring terminal 200.
- the neighboring terminal 200 has a terminal type that is different from the terminal type specified in the terminal information request, or does not have the necessary function specified in the terminal information request, the subsequent processing is performed. Do not, discard request.
- a codec such as MPEG2
- the neighboring terminal 200 that receives the codec is compliant with the designated codec
- the neighboring terminal 200 will receive this terminal information. Terminates processing for the request.
- the transfer source terminal 100 is close.
- a transfer destination candidate terminal is determined based on the terminal information acquired by searching for the neighboring terminal 200 using the distance radio, and only the transfer destination candidate terminal is requested for the connectivity information after the terminal switching.
- the terminal from which the transfer source terminal 100 collects connectivity information can be the only transfer destination destination terminal, the amount of communication processing performed to collect the connectivity information is reduced and less network traffic is collected. Can be switched to an appropriate terminal by using
- the present invention is useful for a communication terminal, and is suitable for switching a communication terminal to be used while a user continues communication.
