<p>A system and method for configuring two different wireless multi-protocol communication networks so that a common telephone number may be shared between telephones communicating over the different networks. Telephone number transparency is provided so that at the subscriber level, both telephones appear to have the same number and can access common subscriber services associated with that number in a substantially identical fashion. An incoming call is first directed to the telephone designated as the "primary telephone", and then to the telephone designated as the "secondary telephone" if the primary telephone is not answered. Although the telephones are associated with the same number, they are able to simultaneously conduct independent communications and may establish a communication link between each other. This arrangement may be put to advantage by a service provider who wishes to migrate a subscriber base from one network technology to another, such as from a TDMA network to a GSM network.</p> |
