Abstract

There is provided a media communication apparatus including an automatic selection unit which automatically selects a telecommunications carrier by preset criteria on the address of a speech terminal serving as a communication destination input at the time of call origination and a communication system which identifies the communication conventions of a server of the selected telecommunications carrier and communicates media in accordance with the communication conventions, wherein the communication system has an automatic identification unit which automatically identifies the communication protocol of the server of the selected telecommunications carrier, a session establishment unit which establishes a session according to the identified communication protocol, and a packet communication unit which communicates media in packets on the basis of the established session.

Claims14

Dependent claims

A media communication apparatus, connected to a calling speech terminal of a communication source which is capable of receiving communication connection services provided by telecommunications carriers, the media communication apparatus comprising:

an auto selection unit automatically selecting a telecommunications carrier on the basis of an address of a speech terminal inputted as a communication destination at a call origination by the calling speech terminal of the communication source, in accordance with a preset criterion;
and
a communication system communicating media between the calling speech terminal of the communication source and the calling speech terminal of the communication destination via a server of the telecommunication carriers selected by the auto selection unit,
wherein the communication system is operable to:
prior to establishing a session with the sever of the selected telecommunication carrier, transmit to the server a request message for establishing a session with the server;
analyze contents of a response message received from the server responsive to the transmission;
identify a type of a communication convention of the sip server used to communicate media on the basis of a result of analyzing the contents of the response message;
and
establish a session with the server in accordance with the identified communication sip convention of the server, and then, communicate media on the basis of the established session,
wherein the communication system identifies a communication convention of the server by analyzing contents of a response message received in response to transmission of a subscribe request for requesting a state of the server in a case where an error message is returned from the server in response to transmission of the request message to the server of the telecommunication carrier selected by the auto selection unit.

A media communication apparatus that is connected to servers of a plurality of communications carriers, a respective one of which adapted to set a communication charge system different from one another, according to a type of a communication terminal of a transmission source and a type of a communication terminal of a transmission destination, and that is set up between the communication terminal of the transmission source and the server, said apparatus comprising:

(i) an auto selection unit having a database which stores communication charge data different depending upon a type of the communication terminal set for a respective one of the plurality of communications carriers, and automatically selecting a server of one of the plurality of communications carriers by correlating an address of the communication terminal of the transmission destination input upon call origination by the communication terminal of the transmission source with the communication charge data stored in the database for a respective one of the plurality of communications carriers;
(ii) a transmission unit for, prior to establishing a session with the server of the communications carrier selected by the auto selection unit, transmitting a request message for establishing the session with the server to the server of the communications carrier selected by the auto selection unit;
(iii) an analysis unit for analyzing contents of a response message received from the server of the communications carrier selected by the auto selection unit responsive to the transmission of the transmission unit;
(iv) an identification unit for identifying a type of a communication convention of the server of the communications carrier selected by the auto selection unit used to communicate media, on the basis of a result of analyzing the contents of the response message by the analysis unit;
and
(v) a communication unit for establishing a session with the server of the communications carrier selected by the auto selection unit, in accordance with the communication convention of the server of the communications carrier selected by the auto selection unit, the communication convention being identified by the identification unit, and then, communicating media between the communication terminals of the transmission source and the transmission destination, via the server of the communications carrier selected by the auto selection unit on the basis of the established session.
