Provision of cellular/wire-line service
First Claim
1. A method of providing telephone service to a telephone Main Station (MS) from and to an arbitrary land-based location not served by a home switch for said MS, comprising the steps of:
- if said MS detects a connection to land-line power from a jack not served by said home switch, calling a server;
transmitting to said server, a secret mobile identification number of said Main Station (MS);
transmitting to said server an incoming calling line identification (ICLID) of said jack serving said MS;
the server transmitting the directory number of said jack to said home switch serving said MS;
routing an incoming call for said MS to said home switch; and
automatically forwarding said incoming call to the MS from said home switch to said directory number;
wherein said home switch is a home land-line switch for providing service to said MS whenever said MS is plugged into a land-line jack for said MS connected to said home land-line switch.

Abstract
Apparatus and a method for providing roaming service to a telecommunications station which can act as a cellular station or if plugged into a jack connected to a land-line switch, can act like a land-line telephone. When such a Universal Main Station (UMS) is plugged into a jack connected to a land-line switch, the station calls a server system which obtains the directory number corresponding to the jack into which the UMS was plugged. The server notifies a home switch of said UMS to forward calls to that directory number. When the UMS subsequently unplugs from the jack, the UMS registers as a mobile station and the home switch is notified to forward calls to the UMS, acting as a mobile station and identified by a secret directory number, identified in the course of the registration. Advantageously, this arrangement allows a mobile station equipped with an arrangement for detecting the presence of land-line power and arranged to substitute signals received from a jack for radio signals to roam widely, and to receive a choice of cellular service or land-line service wherever the station roams.

5. The method of claim 1, wherein said MS has a land-line directory number served by said home switch, and a secret cellular directory number for calling said MS when said MS is powered-up and not connected to a land-line terminal.
- 2. If said server does not automatically receive said ICLID, transmitting an indication from said server to said MS requesting said MS to provide said directory number.
