Method and apparatus for messaging between a client of an sip-based network and a client of a wireless village network

摘要

A method (and corresponding equipment) by which a first device (11a), operable in a first network (11) including an SIP type of network (such as an IMS network) to which the first device (11a) is subscribed, communicates with a second device (12a), operable in a second network (12) including a WV network to which the second device (12a) is subscribed, the method providing routing steps so that each SIP network entity, such as an I-CSCF (11f), that processes the message encounters an SIP addressing scheme, i.e. the addressing scheme native to the SIP type of network, and so that each WV server (12b) encounters only an addressing scheme native to the WV network, after possibly preliminary conversion (A0-D0) to the native addressing scheme. The first network (11) may also include components of a WV network, and the second network (12) may also include components of an SIP type of network.
